    Explicit and implicit weight bias among health care students: a cross-sectional study of 39 Australian universities.2023Inngår i: eClinicalMedicine, E-ISSN 2589-5370, Vol. 58, artikkel-id 101894Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Weight bias exhibited by health care students may continue into their future practice, compromising the provision of care that people living with overweight or obesity receive. This highlights the need to comprehensively examine the extent to which weight bias is present among health care students and the factors that may be associated with students' weight bias.

    METHODS: In this cross-sectional study, Australian university students enrolled in health care courses were invited via social media advertisements, snowball and convenience sampling, and by making direct contact with universities to complete an online survey. Students provided demographic information including discipline of study, perceived weight status, and state of residence. Students then completed several measures which assessed their explicit and implicit weight bias, and empathy. Descriptive statistics established the presence of explicit and implicit weight bias, and ANCOVAs, ANOVA, and multiple regression analyses were conducted to examine the potential factors associated with students' exhibited weight bias.

    FINDINGS: Between March 08, 2022, and March 15, 2022, 900 eligible health care students attending 39 Australian universities participated in the study. Students reported varying levels of explicit and implicit weight bias, with minimal differences between disciplines on most outcome measures. Students who identified as men (vs. women) exhibited higher of both explicit and implicit bias (Beliefs About Obese Persons (BAOP): p = 0.0002, Antifat Attitudes Questionnaire (AFA)-Dislike: p = 0.019, AFA Willpower p < 0.0001, Empathy for Obese Patients: p = 0.0011, Implicit Association Test: p = 0.022), and students who displayed greater (vs. less) empathic concern exhibited lower levels of explicit bias (BAOP, AFA Dislike and Willpower, and Empathy for Obese Patients: p < 0.0001). Having witnessed the enactment of weight stigma sporadically (vs. regularly) by role models was associated with greater attribution of the causes of obesity to willpower (a few times a month vs. daily: p = 0.020, a few times a year vs. daily: p = 0.022), and less time spent with people living with overweight or obesity outside of study was associated with more dislike (a few times a month vs. daily: p = 0.0048, once a month vs. daily: p = 0.0002) and less fear of fat (once a month vs. daily: p = 0.036, and once a month vs. a few times a week: p = 0.0028).

    INTERPRETATION: Results demonstrate the presence of both explicit and implicit weight bias among Australian health care students. Several characteristics and experiences of students were associated with their weight bias. Validity of the exhibited weight bias should be established in practical interactions with people living with overweight or obesity and novel interventions should be developed to ameliorate weight bias.

    Acute effects of physical exercise of different intensities on working memory: Masters thesis2023Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Aim: The purpose of this study was to investigate acute effects of physical exercise of different intensities on working memory.

    Method: Twelve young adults, 20-40 years, 8 males and 4 females passed the screening and participated in a randomized experimental crossover within-subject design study with three experimental conditions. Working memory was measured with n-back consisting of three difficulty levels. 

    Results: No significant interaction effect within subjects between the three different exercise intensity conditions for accuracy or response time was found. A significant main effect of time was detected for n-back response time, F(1,11)=40.2, p=<.001, reflecting an overall shorter response time after exercise compared to before, independent of exercise intensity condition. A two-way interaction effect on accuracy was found between n-back session 1 and 2 in the low fitness group. 

    Conclusions: The exercise intensity does not seem to matter for the improvement of working memory performance. However, participants response time was shown to be faster following any given exercise intensity.

    The influence of initial selection age, relative age effect and country long-term performance on the re-selection process in European basketball youth national teams2021Inngår i: Journal of Sports Sciences, ISSN 0264-0414, E-ISSN 1466-447X, Vol. 39, nr 4, s. 388-394Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aims of the study were to: (a) analyse the re-selection patterns in European youth basketball national teams, and (b) investigate how the chance of re-selection is influenced by the initial selection age and relative age of the players, as well as the long-term performance of the country at the youth level. The sample consisted of 8362 basketball players (5038 men, 3324 women) born 1988-1997 who have participated in at least one U16, U18 or U20 European youth basketball championship between 2004 and 2017. The results from the survival analysis showed that around 75% of male and 80% of female players participating in a championship were re-selected the following year. Also, initial selection age, relative age effect, and the country long-term performance influenced the re-selection rates, with relationships being different between men and women. To conclude, the results of the present study show that the re-selection process by which players progress in European youth national basketball teams is complex and influenced by several different factors.

    Workplace sitting is associated with self-reported general health and back/neck pain: a cross-sectional analysis in 44,978 employees.2021Inngår i: BMC Public Health, E-ISSN 1471-2458, Vol. 21, nr 1, artikkel-id 875Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Total sitting time is associated with a higher risk for cardio metabolic disease and mortality, while breaks in prolonged sitting attenuate these effects. However, less is known about associations of different specific domains and breaks of sitting on general health, back/neck pain and if physical activity could influence these associations. The aim was to investigate how workplace sitting and frequency of breaking up workplace sitting is associated with self-reported general health and self-reported back/neck pain.

    METHODS: 44,978 participants (42% women) from the Swedish working population, who participated in a nationwide occupational health service screening 2014-2019, were included in this cross-sectional study. Self-reported sitting duration and frequency of breaks from sitting at work, general health, back/neck pain, exercise, leisure time sitting, diet, smoking, stress and body mass index were assessed. Occupation was classified as requiring higher education qualifications or not. Logistic regression modelling was used to assess the association between workplace sitting/frequency of breaks in workplace sitting and poor general health and back/neck pain, respectively.

    RESULTS: Compared to sitting all the time at work, sitting ≤75% of the time showed significantly lower risks for poor general health (OR range 0.50-0.65), and sitting between 25 and 75% of the time showed significantly lower risks (OR 0.82-0.87) for often reported back/neck pain. For participants reporting sitting half of their working time or more, breaking up workplace sitting occasionally or more often showed significantly lower OR than seldom breaking up workplace sitting; OR ranged 0.40-0.50 for poor health and 0.74-0.81 for back/neck pain.

    CONCLUSIONS: Sitting almost all the time at work and not taking breaks is associated with an increased risk for self-reported poor general health and back/neck pain. People sitting almost all their time at work are recommended to take breaks from prolonged sitting, exercise regularly and decrease their leisure time sitting to reduce the risk for poor health.

    The role of domain-specific and domain-general cognitive functions and skills in sports performance: A meta-analysis2021Inngår i: Psychological bulletin, ISSN 0033-2909, E-ISSN 1939-1455, Vol. 147, nr 12, s. 1290-1308Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Cognition plays a key role in sports performance. This meta-analytic review synthesizes research that examined the relationship between cognitive functions, skills, and sports performance. We identified literature by searching Cochrane Library, APA PsycINFO, PubMed, and Web of Science. We included studies conducted on competitive athletes, assessed cognitive prerequisites, and included performance measures related to the sport. Of the 9,433 screened records, 136 reports were included, containing 142 studies, 1,227 effect sizes, and 8,860 participants. Only 11 studies used a prospective study design. The risk of bias was assessed using the Risk of Bias Assessment Tool for Nonrandomized Studies. The multilevel meta-analysis showed a medium effect size for the overall difference in cognitive functions and skills, with higher skilled athletes scoring better than lower skilled athletes (Hedges' g = 0.59, 95% CI [0.49, 0.69]). The moderator analysis showed larger effect size for tests of cognitive decision-making skills (g = 0.77, 95% CI [0.6, 0.94]) compared to basic (g = 0.39, 95% CI [0.21, 0.56]) and higher cognitive functions (g = 0.44, 95% CI [0.26, 0.62]), as well as larger effect for sport-specific task stimuli compared to general ones. We report that higher skilled athletes perform better on cognitive function tests than lower skilled athletes. There was insufficient evidence to determine whether cognitive functions and skills can predict future sport performance. We found no evidence to support claims that tests of general cognitive functions, such as executive functioning, should be used by practitioners for talent identification or player selection.

    Public Significance Statement This meta-analysis indicates that testing cognitive functions or skills using sport-specific stimuli has the potential to differentiate between elite and nonelite athletes. There is, however, no evidence for the usefulness of using general, non-sport-specific cognitive function tests to predict future sport performance.

    Force Generation Profiles of Para-Nordic Sit-Skiers Representing Different Physical Impairments2021Inngår i: Journal of Science in Sport and Exercise, ISSN 2662-1371, Vol. 3, s. 281-291Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose

    To biomechanically profile force generation connected to the complex role of the trunk in double poling in a representative sample of Para-Nordic sit-skiers.

    Methods

    Twelve male World Cup Para-Nordic sit-skiers (sport classes: LW10–12) were skiing on flat snow terrain at submaximal speed of 4.5 m/s (~ 73% maximum speed). 2D video (50 Hz) and pole force analyses (1000 Hz) were performed synchronously, examining angle, force and cycle characteristics to analyse the role of the trunk in generating propulsion.

    Results

    LW10–11.5 skiers lost between 21% and 4% propulsive force versus LW12 athletes only due to different geometrics of the trunk and pole angle at an equal axial pole force. While LW10–11 skiers indicated trunk extension or position maintenance during pole thrust, LW11.5–12 skiers showed strong trunk flexion combined with smaller pole angles to the ground. Hence, LW11.5–12 skiers could create larger propulsive forces and therefore greater cycle lengths at lower cycle rates at the same speed. Maximum speed increased from LW10 to LW12 and was significantly correlated to trunk flexion range of motion (r = 0.63) and cycle length (r = 0.59). Trunk flexion ROM showed a significant relationship to the impulse of propulsive force (r = 0.63) and pole angle to the ground (r = − 0.76) (all P < 0.05).

    Conclusion

    The impact of impairment on the force production profiles and its physiological-biomechanical consequences need further investigation also in other terrains and at wider spectrums of skiing speeds. The evident problem of low numbers of LW10–11 skiers in World Cup needs creative future solutions for research.

    Rörelseglädje på ett kravlöst och prestationsfritt sätt: En kvalitativ studie om hur elever med problematisk skolfrånvaro upplever fysisk aktivitet under skoltid2023Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syfte och frågeställning

    Syftet med denna studie var att få kunskap om hur elever med problematisk skolfrånvaro, i årskurs 7-9, upplevde fysisk aktivitet under skoltid och hur man kan främja mer fysisk aktivitet under skoltid framöver för dessa elever. För att uppnå syftet och svara på våra frågeställningar genomfördes en fysisk aktivitets intervention. Frågeställningar: 1) Hur upplever elever med problematisk skolfrånvaro fysisk aktivitet under skoltid (skolidrott och en fysisk aktivitets intervention)? 2) Vad finns det för upplevda framgångsfaktorer till att elever med problematisk skolfrånvaro deltar på skolidrotten och interventionen och vad finns det för upplevda hinder till att de väljer att inte delta? 3) Hur kan man främja mer fysisk aktivitet under skoltid framöver för elever med problematisk skolfrånvaro?

    Metod

    För att besvara studiens syfte och frågeställningar användes en kvalitativ induktiv metod med fokus på semistrukturerade intervjuer. Före intervjuerna genomfördes en fysisk aktivitets intervention. Deltagarna var 13 högstadieelever med problematisk skolfrånvaro från en skola i ett socioekonomiskt utsatt område i Stockholm. Intervjuerna spelades in, transkriberades och analyserades utifrån en manifest innehållsanalys. Studiens teoretiska ramverk var Self-Determination Theory (SDT).

    Resultat

    Analysen mynnade ut i följande fyra huvudteman: Upplevda framgångsfaktorer och upplevda hinder till fysisk aktivitet under skoltid, upplevelse av interventionen samt främja fysisk aktivitet under skoltid framöver. Huvudresultaten visar att vänner är en viktig framgångs-faktor till att delta i fysisk aktivitet under skoltid och det finns indikationer på att inter-ventionen ledde till att respondenterna upplevde en förbättrad fysisk och psykisk hälsa, bättre sammanhållning och ökad studiemotivation. Närvaron under interventionen var hög och majoriteten av respondenterna var mer motiverade att komma till skolan de dagar interventionen pågick.

    Slutsats

    Studiens resultat är inte generaliserbart, däremot har resultatet lett till en ökad kunskap och större förståelse för hur 13 elever med problematisk skolfrånvaro upplever fysisk aktivitet under skoltid. Forskning kring problematisk skolfrånvaro i kombination med fysisk aktivitet är i nuläget bristfällig och denna utforskande studie kan därför vara en bra grund för kommande kvantitativa studier på området.

    Going web or staying paper? The use of web-surveys among older people.2020Inngår i: BMC Medical Research Methodology, E-ISSN 1471-2288, Vol. 20, nr 1, artikkel-id 252Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Web-surveys are increasingly used in population studies. Yet, web-surveys targeting older individuals are still uncommon for various reasons. However, with younger cohorts approaching older age, the potentials for web-surveys among older people might be improved. In this study, we investigated response patterns in a web-survey targeting older adults and the potential importance of offering a paper-questionnaire as an alternative to the web-questionnaire.

    METHODS: We analyzed data from three waves of a retirement study, in which a web-push methodology was used and a paper questionnaire was offered as an alternative to the web questionnaire in the last reminder. We mapped the response patterns, compared web- and paper respondents and compared different key outcomes resulting from the sample with and without the paper respondents, both at baseline and after two follow-ups.

    RESULTS: Paper-respondents, that is, those that did not answer until they got a paper questionnaire with the last reminder, were more likely to be female, retired, single, and to report a lower level of education, higher levels of depression and lower self-reported health, compared to web-respondents. The association between retirement status and depression was only present among web-respondents. The differences between web and paper respondents were stronger in the longitudinal sample (after two follow-ups) than at baseline.

    CONCLUSIONS: We conclude that a web-survey might be a feasible and good alternative in surveys targeting people in the retirement age range. However, without offering a paper-questionnaire, a small but important group will likely be missing with potential biased estimates as the result.

    Förekomsten av amenorré och energitillgänglighet hos kvinnor som tränar CrossFit2021Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syfte och frågeställningar

    Syftet med studien var att undersöka om amenorré samt låg energitillgång förekommer bland kvinnliga CrossFitutövare. Fyra frågeställningar besvaras i studien: 1) Hur ser förekomsten av amenorré ut bland kvinnor som utövar CrossFit? 2) Finns det ett samband mellan träningsfrekvens/intensitet och förekomst av amenorré? 3) Finns det ett samband mellan kaloriintag och förekomst av amenorré? 4) Finns det ett samband mellan restriktiv kost och förekomst av amenorré?

    Metod

    Studien är en kvantitativ tvärsnittsstudie och genomfördes med hjälp av en enkätundersökning för att identifiera nivåer av träningsvanor, kostintag samt frånvaro av menstruation. Studien involverade 188 kvinnor med en medelålder på 31 år (SD ± 7.3).

    Resultat

    En högre procent av deltagarna (56,4%) har haft förekomst av amenorré. Ett signifikant samband hittades mellan energiintag och förekomsten av amenorré (p=0.004). Oddsen att drabbas av amenorré för de som tränar 5–7 pass i veckan är nästan dubbelt så högt jämfört med de som tränar 0–4 pass i veckan (p=0.04). De som äter >2400 kalorier per dag har 70% lägre odds att drabbas av amenorré jämfört med de som äter 1900–2300 kalorier per dag.

    Slutsats

    Detta är den första studien som har undersökt amenorré och energitillgång hos kvinnliga CrossFitutövare genom en tvärsnittsstudie. Utifrån deltagarnas svar finns det en förekomst av amenorré bland kvinnliga CrossFitutövare. En stor del inom gruppen verkar inte nå upp till en god energitillgänglighet. Resultatet bör tolkas med försiktighet då ett flertal uppgifter baseras på uppskattningar.

    Cross-sectional associations between physical activity pattern, sports participation, screen time and mental health in Swedish adolescents.2022Inngår i: BMJ Open, E-ISSN 2044-6055, Vol. 12, nr 8, artikkel-id e061929Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: To investigate the associations between physical activity pattern, sports participation, screen time and mental health in Swedish adolescents.

    DESIGN, SETTING AND PARTICIPANTS: A total of 1139 Swedish adolescents (mean age 13.4) from 34 schools participated in the cross-sectional study 'Physical Activity for Healthy Brain Functions in School Youth' in 2019.

    METHODS: Time spent sedentary and in moderate-to-vigorous physical activity (MVPA) was measured using accelerometers for seven consecutive days. Screen time and sports participation were self-reported. Anxiety and health-related quality of life (HRQoL) were assessed using a Short version of the Spence Children's Anxiety Scale and Kidscreen-10.

    RESULTS: MVPA was positively associated (95% CI 0.01 to 0.05 in girls and 0.02 to 0.07 in boys) whereas screen time on weekdays was inversely associated with HRQoL (-4.79 to -2.22 in girls and -2.66 to -0.41 in boys). The largest effect sizes were observed between the high/low MVPA group in boys (Cohen's d=0.51) and screen time groups in girls (Cohen's d=0.59 on weekdays). With regards to anxiety, high compared with lower time spent in MVPA during leisure time on weekdays was associated with lower anxiety scores (95% CI -0.13 to -0.05 in girls and -0.07 to -0.01 in boys). Gender differences were observed, boys who participated in organised sports had low anxiety scores (95% CI -3.49 to -0.13) whereas girls who reported 5 hours or more of screen time had high scores (95% CI 1.94 to 6.18 on weekdays and 1.39 to 5.29 on weekend days).

    CONCLUSIONS: This study showed that MVPA was associated with better mental health, whereas the opposite was seen for screen time. These associations were not consistently significant throughout all time domains, between the genders and mental health outcomes. Our results could create a paradigm for future studies to decide which types of PA patterns and time domains to target in intervention studies with the aim improve mental health among adolescents.

    Associations between Physical Activity Patterns, Screen Time and Cardiovascular Fitness Levels in Swedish Adolescents2021Inngår i: Children, E-ISSN 2227-9067, Vol. 8, nr 11, artikkel-id 998Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Cardiovascular fitness (CVF) has been associated with cardiovascular risk factors in adolescents. CVF levels are determined by non-modifiable and modifiable factors; one modifiable factor is physical activity (PA). There is a lack of studies investigating the associations between PA patterns and CVF and how gender, parental education, BMI status and country of birth are associated with CVF. The aim of this study was to explore the cross-sectional associations between PA patterns and CVF in Swedish 13–14-year-old adolescents. CVF was estimated using the Ekblom-Bak submaximal test, data on PA patterns were collected using hip-worn accelerometers and a questionnaire. The mean CVF was 44.8 mL/kg/min in girls (n = 569) and 55.5 mL/kg/min in boys (n = 451) p < 0.01. The results showed a significant association between participation in organised sports (β = 3.32 CI: 2.14, 4.51, β = 4.38, CI: 2.80, 5.96), MVPA (β = 0.07, CI: 0.04, 0.11, β = 0.07, CI: 0.03, 0.11), a high proportion of SED (β = −0.47, CI: −0.70, −0.25, β = −0.41, CI: −0.64, −0.18) and CVF in girls and boys, respectively. More than five hours of screen time on weekdays was associated with lower CVF (β = −2.32 CI: −3.92, −0.71 in girls and boys β = −2.82, CI: −5.14, −0.50). While causal relations remain unknown, these findings could be relevant when designing future interventions with the aim to improve CVF.

    Short, frequent physical activity breaks improve working memory in adolescents during prolonged sitting (AbbaH teen study)2023Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Purpose: Physical activity breaks in schools have been suggested as a promising strategy to acutely improve cognitive performance in children and adolescents. Most previous studies have explored the effects of single physical activity bouts, but they are infeasible in a school setting (e.g. long duration/high-intensity or requiring equipment/space). Further, studies investigating the underlying physiological mechanisms in adolescents arel acking. Therefore, the aim of this study was to investigate the effects of short, frequent physical activity breaks of different intensities on adolescents’ working memory (WM) and cerebral blood flow (CBF) during prolonged sitting.

    Methods: This randomized crossover study was performed in adolescents (13-15 years of age). In 80-minute sessions, one of the following types of breaks was performed four times in three minutes durations on three different days: simple resistance training (SRA), step-up at a pre-determined pace (STEP), or remaining seated (SOCIAL). Before and after each session, WM (accuracy and reaction time during the 1,2,3-back test) were measured, with simultaneous measurement of task-related CBF (assessed by prefrontal oxygenation using functional near-infrared spectroscopy). Analysis of CBF is ongoing and will be presented at the conference.

    Results: A total of 17 students participated (mean age 13.6 years, 11 girls). In the most demanding task (3-back) the following results were seen: improvement in reaction time following SRA (-30.1, p=0.04) and STEP (-34.3 ms, p=0.05) and no improvement following prolonged sitting. We also found a moderating effect (p <0.01) of WM performance at baseline (using a mean split), such that students with poor WM significantly improved their accuracy and reaction time following the higher-intensity breaks (STEP) while students with high performance did not.

    Conclusion: We found that implementing physical activity breaks of both moderate and high intensities was beneficial for WM performance. For students with low WM performance, high-intensity breaks were more beneficial. Implementing physical activity breaks during periods of prolonged sitting, such as long school classes could improve the students’ cognitive performance. However, future studies should investigate if these breaks are feasible, acceptable, and beneficial to implement in the school setting.

    Har man mer ångest om man sover dåligt?: Samband mellan sömn och ångest hos tonåringar i årskurs 72022Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syfte och frågeställningar | Syftet med studien var att undersöka om det fanns samband mellan sömn och ångestsymptom hos 13–14 åringar. Syftet var även att studera hur sambandet såg ut när pojkar och flickor analyserades separat och med hänsyn taget till föräldrautbildning och fysisk aktivitet. Frågeställningar: 1) Finns det samband mellan sömnlängd och ångestsymptom? 2) Finns det samband mellan sömnkvalitet och ångestsymptom? 3) Hur är sambandet mellan sömnlängd och ångestsymptom, sömnkvalitet och ångestsymptom hos flickor och pojkar? 4) Hur är sambandet mellan sömnlängd och ångestsymptom, sömnkvalitet och ångestsymptom hos deltagare med hög och låg föräldrautbildning? 5) Hur är sambandet mellan sömnlängd och ångestsymptom, sömnkvalitet och ångestsymptom hos deltagare som uppnår rekommenderad fysisk aktivitet och inte?

    Metod | Studien är en kvantitativ tvärsnittsstudie med data från projektet “Physical Activityfor Healthy Brain Functions in School Youth”. I studien deltog 1139 tonåringar varav 580 flickor, 558 pojkar och 1 annat kön. Medelåldern (SD) för deltagarna var 13.4 ± 0.3 år.

    Resultat | Studien visade svagt negativt signifikant samband mellan ångestsymptom och sömnlängd på vardag hos hela studiepopulationen (r=-0.068, p=0.027), hos flickor (r=-0.098,p=0.022), hos tonåringar med hög föräldrautbildning (r=-0.094, p=0.014) och hos deltagare som inte uppnådde rekommendationerna för fysisk aktivitet (<60 min/dag) (r=-0.115, p<0.002). Ytterligare fynd visade svagt signifikant negativt samband mellan ångestsymptom och sömnkvalitet hos hela gruppen (r=-0.242, p=0.001), hos flickor (r=-0.221, p=0.001), hos pojkar (r=-0.226, p=0.001), hos båda utbildningsgrupperna (≤12 år och >12 år) (r=-0.212,p=0.001 och r=-0.238, p=0.001), samt hos båda grupperna för fysisk aktivitet (<60 min/dagoch >60 min/dag) (r=-0.217, p<0.01 och r=-0.225, p<0.01).

    Slutsats | Resultaten visar svaga negativa samband mellan ångestsymptom och sömnlängd på vardag, och sömnkvalitet hos tonåringar. Flickor rapporterade mindre sömnlängd, fysisk aktivitet och mer ångestsymptom jämfört med pojkar. Denna studie stödjer inte ett orsakssamband, vidare forskning med annan studiedesign krävs.

    Eveningness is associated with coronary artery calcification in a middle-aged Swedish population2024Inngår i: Sleep Medicine, ISSN 1389-9457, E-ISSN 1878-5506, Vol. 113, s. 370-377Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Coronary artery calcification (CAC) is an established imaging biomarker of subclinical atherosclerosis, but its relationship to diurnal preference is not well studied. We investigated the association between chronotype and CAC in the Swedish CArdioPulmonary bioImage Study (SCAPIS) pilot cohort. Participants aged 50–64 years were randomly recruited and underwent extensive examination including imaging and accelerometry-assessed physical activity. 771 participants (47.3 % male, 57.6 ± 4.4 years) were included in this cross-sectional analysis. CAC was assessed by non-contrast computed tomography, and a CAC score > 10 was considered significant calcification. Self-assessed chronotype was classified as extreme morning, moderate morning, intermediate, moderate evening, or extreme evening. 10-year risk of first-onset cardiovascular disease was estimated by the Systemic Coronary Risk Evaluation 2 (SCORE2). Significant CAC was present in 29 % of the cohort. CAC prevalence increased from extreme morning to extreme evening type (22 %, 28 %, 29 %, 27 %, 41 % respectively, p = 0.018). In a multivariate logistic regression model controlling for confounders, extreme evening chronotype was independently associated with increased CAC prevalence compared to extreme morning type (OR 1.90, [95%CI 1.04–3.46], p = 0.037). When stratified by SCORE2 risk category (low: <5 %; moderate: 5 to <10 %; high: ≥10 %), significant CAC was most prevalent among extreme evening chronotypes in the low and moderate-risk groups, while chronotype seemed less important in the high-risk group (p = 0.011, p = 0.023, p = 0.86, respectively). Our findings suggest circadian factors may play an important role in atherosclerosis and should be considered in early cardiovascular prevention.

    Eveningness is associated with sedentary behavior and increased 10-year risk of cardiovascular disease: the SCAPIS pilot cohort.2022Inngår i: Scientific Reports, E-ISSN 2045-2322, Vol. 12, nr 1, artikkel-id 8203Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Chronotype reflects individual preferences for timing activities throughout the day, determined by the circadian system, environment and behavior. The relationship between chronotype, physical activity, and cardiovascular health has not been established. We studied the association between chronotype, physical activity patterns, and an estimated 10-year risk of first-onset cardiovascular disease (CVD) in the Swedish CArdioPulmonary bioImage Study (SCAPIS) pilot cohort. A cross-sectional analysis was performed in a middle-aged population (n = 812, 48% male). Self-assessed chronotype was classified as extreme morning, moderate morning, intermediate, moderate evening, or extreme evening. Time spent sedentary (SED) and in moderate to vigorous physical activity (MVPA) were derived from hip accelerometer. The newly introduced Systematic COronary Risk Evaluation 2 (SCORE2) model was used to estimate CVD risk based on gender, age, smoking status, systolic blood pressure, and non-HDL cholesterol. Extreme evening chronotypes exhibited the most sedentary lifestyle and least MVPA (55.3 ± 10.2 and 5.3 ± 2.9% of wear-time, respectively), with a dose-dependent relationship between chronotype and SED/MVPA (p < 0.001 and p = 0.001, respectively). In a multivariate generalized linear regression model, extreme evening chronotype was associated with increased SCORE2 risk compared to extreme morning type independent of confounders (β = 0.45, SE = 0.21, p = 0.031). Mediation analysis indicated SED was a significant mediator of the relationship between chronotype and SCORE2. Evening chronotype is associated with unhealthier physical activity patterns and poorer cardiovascular health compared to morning chronotype. Chronotype should be considered in lifestyle counseling and primary prevention programs as a potential modifiable risk factor.

    Distance-based delivery of exercise for people treated for breast, prostate or colorectal cancer: a study protocol for a randomised controlled trial of EX-MED Cancer Sweden.2023Inngår i: Trials, E-ISSN 1745-6215, Vol. 24, nr 1, s. 116-, artikkel-id 116Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Regular exercise has been shown to have beneficial health effects in cancer survivors, including improving quality of life and other important health outcomes. However, providing people with cancer with easily accessible, high-quality exercise support and programs is a challenge. Therefore, there is a need to develop easily accessible exercise programs that draw upon the current evidence. Supervised, distance-based exercise programs have the benefit of reaching out to many people whilst providing the support of an exercise professional. The aim of the EX-MED Cancer Sweden trial is to examine the effectiveness of a supervised, distance-based exercise program, in people previously treated for breast, prostate, or colorectal cancer, on health-related quality of life (HRQoL), as well as other physiological and patient-reported health outcomes.

    METHODS: The EX-MED Cancer Sweden trial is a prospective randomised controlled trial including 200 people that have completed curative treatment for breast, prostate, or colorectal cancer. Participants are randomly allocated to an exercise group or a routine care control group. The exercise group will participate in a supervised, distanced-based exercise program delivered by a personal trainer who has undertaken specialised exercise oncology education modules. The intervention consists of a combination of resistance and aerobic exercises with participants completing two 60-min sessions per week for 12 weeks. The primary outcome is HRQoL (EORTC QLQ-C30) assessed at baseline, 3- (end of intervention and primary endpoint) and 6-months post-baseline. Secondary outcomes are physiological (cardiorespiratory fitness, muscle strength, physical function, body composition) and patient-reported outcomes (cancer-related symptoms, fatigue, self-reported physical activity), and self-efficacy of exercise. Furthermore, the trial will explore and describe the experiences of participation in the exercise intervention.

    DISCUSSION: The EX-MED Cancer Sweden trial will provide evidence regarding the effectiveness of a supervised, distance-based exercise program for survivors of breast, prostate, and colorectal cancer. If successful, it will contribute to the implementation of flexible and effective exercise programs as part of the standard of care for people following cancer treatment, which is likely to contribute to a reduction in the burden of cancer on the individual, health care system and society.

    Steering Does Affect Biophysical Responses in Asynchronous, but Not Synchronous Submaximal Handcycle Ergometry in Able-Bodied Men.2021Inngår i: Frontiers in Sports and Active Living, E-ISSN 2624-9367, Vol. 3, artikkel-id 741258Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Real-life daily handcycling requires combined propulsion and steering to control the front wheel. Today, the handcycle cranks are mostly mounted synchronously unlike the early handcycle generations. Alternatively, arm cycle ergometers do not require steering and the cranks are mostly positioned asynchronously. The current study aims to evaluate the effects of combining propulsion and steering requirements on synchronous and asynchronous submaximal handcycle ergometry. We hypothesize that asynchronous handcycling with steering results in the mechanically least efficient condition, due to compensation for unwanted rotations that are not seen in synchronous handcycling, regardless of steering. Sixteen able-bodied male novices volunteered in this lab-based experiment. The set-up consisted of a handcycle ergometer with 3D force sensors at each crank that also allows "natural" steering. Four submaximal steady-state (60 rpm, ~35 W) exercise conditions were presented in a counterbalanced order: synchronous with a fixed steering axis, synchronous with steering, asynchronous with a fixed axis and asynchronous with steering. All participants practiced 3 × 4 mins with 30 mins rest in between every condition. Finally, they did handcycle for 4 mins in each of the four conditions, interspaced with 10 mins rest, while metabolic outcomes, kinetics and kinematics of the ergometer were recorded. The additional steering component did not influence velocity, torque and power production during synchronous handcycling and therefore resulted in an equal metabolically efficient handcycling configuration compared to the fixed condition. Contrarily, asynchronous handcycling with steering requirements showed a reduced mechanical efficiency, as velocity around the steering axis increased and torque and power production were less effective. Based on the torque production around the crank and steering axes, neuromuscular compensation strategies seem necessary to prevent steering movements in the asynchronous mode. To practice or test real-life daily synchronous handcycling, a synchronous crank set-up of the ergometer is advised, as exercise performance in terms of mechanical efficiency, metabolic strain, and torque production is independent of steering requirements in that mode. Asynchronous handcycling or arm ergometry demands a different handcycle technique in terms of torque production and results in higher metabolic responses than synchronous handcycling, making it unsuitable for testing.

    How Accurate and Precise Can We Measure the Posture and the Energy Expenditure Component of Sedentary Behaviour with One Sensor?2021Inngår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 18, nr 11, artikkel-id 5782Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Sedentary behaviour is an emergent public health topic, but there is still no method to simultaneously measure both components of sedentary behaviour-posture and energy expenditure-with one sensor. This study investigated the accuracy and precision of measuring sedentary time when combining the proprietary processing of a posture sensor (activPAL) with a new energy expenditure algorithm and the proprietary processing of a movement sensor (ActiGraph) with a published posture algorithm. One hundred office workers wore both sensors for an average of 7 days. The activPAL algorithm development used 38 and the subsequent independent method comparison 62 participants. The single sensor sedentary estimates were compared with Bland-Atman statistics to the Posture and Physical Activity Index, a combined measurement with both sensors. All single-sensor methods overestimated sedentary time. However, adding the algorithms reduced the overestimation from 129 to 21 (activPAL) and from 84 to 7 min a day (ActiGraph), with far narrower 95% limits of agreements. Thus, combining the proprietary data with the algorithms is an easy way to increase the accuracy and precision of the single sensor sedentary estimates and leads to sedentary estimates that are more precise at the individual level than those of the proprietary processing are at the group level.

    Is Sitting Always Inactive and Standing Always Active? A Simultaneous Free-Living activPal and ActiGraph Analysis.2020Inngår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 17, nr 23, artikkel-id E8864Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Sedentary Behavior (SB), defined as sitting with minimal physical activity, is an emergent public health topic. However, the measurement of SB considers either posture (e.g., activPal) or physical activity (e.g., ActiGraph), and thus neglects either active sitting or inactive standing. The aim of this study was to determine the true amount of active sitting and inactive standing in daily life, and to analyze by how much these behaviors falsify the single sensors' sedentary estimates. Sedentary time of 100 office workers estimated with activPal and ActiGraph was therefore compared with Bland-Altman statistics to a combined sensor analysis, the posture and physical activity index (POPAI). POPAI classified each activPal sitting and standing event into inactive or active using the ActiGraph counts. Participants spent 45.0% [32.2%-59.1%] of the waking hours inactive sitting (equal to SB), 13.7% [7.8%-21.6%] active sitting, and 12.0% [5.7%-24.1%] inactive standing (mean [5th-95th percentile]). The activPal overestimated sedentary time by 30.3% [12.3%-48.4%] and the ActiGraph by 22.5% [3.2%-41.8%] (bias [95% limit-of-agreement]). The results showed that sitting is not always inactive, and standing is not always active. Caution should therefore be paid when interpreting the activPal (ignoring active sitting) and ActiGraph (ignoring inactive standing) measured time as SB.

    Från burpee till bebis: En kvantitativ enkätstudie om gravida kvinnors fysiska aktivitetsnivå samt stödet från barnmorskan2023Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syfte och frågeställningar: Syftet med studien var att undersöka hur den fysiska aktivitetsnivån förändrades hos kvinnor vid graviditet, gravida kvinnors åsikter och upplevelser om stöd kring fysisk aktivitet hos barnmorskemottagningen samt om den fysiska aktivitetsnivån skiljde sig mellan olika subgrupper. Frågeställningarna var följande: Hur förändras den fysiska aktivitetsnivån hos kvinnor när de är gravida? Hur informeras gravida kvinnor om fysisk aktivitet och anser de att de får ett tillräckligt stöd av sin barnmorska? Finns det skillnader i fysisk aktivitetsnivå hos gravida kvinnor beroende på trimester, BMI innan graviditet, upplevelse av tillräckligt stöd från barnmorska och att på eget initiativ tagit upp frågan om fysisk aktivitet med sin barnmorska?

    Metod: För att undersöka gravida kvinnors beteenden gällande fysisk aktivitet samt deras upplevelser och åsikter kring stöd inom mödravården, valdes en kvantitativ metod med tvärsnittsdesign. Studiens inklusionskriterier var att vara gravid samt inskriven på en barnmorskemottagning. Datan samlades in genom en webbenkät. Enkäten bestod av bakgrundsfrågor gällande om kvinnorna var inskrivna hos en barnmorskemottagning, ålder, graviditetsvecka, om de hade barn sedan tidigare och i så fall hur många, vikt och längd samt beteende- och åsiktsfrågor kring fysisk aktivitet, information samt stöd från barnmorskor. Datainsamlingen pågick från åttonde januari till tjugoandra januari år 2023.

    Resultat: Resultatet från 393 gravida kvinnor visade att den fysiska aktivitetsnivån minskade hos 81% av deltagarna jämfört med innan graviditeten. 317 respondenter fick information om fysisk aktivitet från sin barnmorska samtidigt som många upplevde att de delvis (n= 176) eller inte alls (n= 54) fått ett tillräckligt stöd kring fysisk aktivitet. Signifikanta skillnader i den fysiska aktivitetsnivån vad gäller fysisk- och muskelstärkande träning sågs beroende på trimester, BMI före graviditet, upplevelse av ett tillräckligt stöd från barnmorskan samt att självmant tagit upp frågan om fysisk aktivitet med barnmorskan (p< 0,05). En signifikant skillnad på högre vardagsmotion sågs hos de kvinnor som självmant hade tagit upp frågan kring fysisk aktivitet med sin barnmorska (p= 0,010).

    Slutsats: För en stor andel gravida kvinnor verkar den fysiska aktivitetsnivån minska under graviditeten. Många gravida kvinnor får information kring fysisk aktivitet av sin barnmorska men upplever samtidigt en brist på ett tillräckligt stöd angående fysisk aktivitet samt en önskan efter ett bättre sådant. För en högre fysisk aktivitetsnivå verkar det vara gynnsamt med ett tillräckligt stöd från barnmorskan samt att den gravida kvinnan har ett eget intresse för fysisk aktivitet.

    Frisk- och riskfaktorer för sjukfrånvaro i arbetslivet: En kvantitativ tvärsnittsstudie på arbetande vuxna2022Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syfte & Frågeställningar: Syftet med denna studie var att undersöka förhållandet mellan parametrarna: Träning ochvardagsmotion, Psykisk hälsa och Arbetsmiljö i relation till sjukfrånvaro. Utöver detta fannsett sekundärt syfte i att kunna ge en grov riktning för organisationer om prioriteringen avinsatser för att minska sjukfrånvaro.

    1. Skiljer sig sjukfrånvaro mellan grupper med olika nivåer av rapporterad mängd träningoch vardagsmotion?

    2. Skiljer sig sjukfrånvaro mellan grupper med olika nivåer rapporteradstress och psykisk hälsa?

    3. Skiljer sig sjukfrånvaro mellan grupper med olika nivåerrapporterad kvalité på arbetsmiljö?

    Metod: Studien baserades på data insamlat från 312 personer genom en enkätundersökning somomfattade frågor om mängd styrketräning, konditionsträning och vardagsmotion samtfrågebatterier för att undersöka den psykiska hälsan och den upplevda arbetsmiljön. Även sjukfrånvaro efterfrågades i “antal dagar det senaste året” och “antal tillfällen det senaste året”. Analyser har genomförts genom binomial logistisk regression genom dikotomiseringar avrespektive beroende variabel. Dikotomiseringarna har gjorts på flera index som omfattar deolika exponeringarna och utfallen. Resultaten beskrevs genom oddskvoter (OR) med ensignifikansnivå på 95%.

    Resultat: Minskad risk för sjukdagar men inte för tillfällen sågs för Index för Träning & Vardagsmotionmed 41,3% (p=0,046). Minskad risk för sjukdomstillfällen men inte för dagar sågs förStyrketräning med 45,4% (p=0,013). Minskad risk för både dagar och tillfällen såg förKonditionsträning med 47,3% lägre (p=0,016) /39,3% (p=0,037, Arbetsmiljö med 41,4 %(p=0,047/ 51,6% (p=0,003) och Psykisk hälsa med 48,6% (p=0,015) / 38,1% (p=0,046). För Vardagsmotion sågs ingen minskad risk för vare sig dagar eller tillfällen.

    Slutsats: Arbetsmiljö, psykisk hälsa och konditionsträning har betydelse för mängden sjukfrånvaro isamtliga utfall, medan styrketräning endast har en signifikant oddskvot på antal tillfällen(frekvens) sjukfrånvaro uppstått. Vardagsmotion verkar inte ha någon skyddande effekt motsjukfrånvaro.

    Movement behavior and mental health in office workers: Associations and intervention effects2023Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Mental disorders pose a significant global health challenge. To effectively address this challenge, mental health promotion must be included in various sectors, including workplaces. Various strategies for promoting mental health in the workplace have been suggested, including interventions aimed at improving movement behavior, i.e., sitting less and moving more. Physical activity (PA) and sedentary behavior (SED) are established determinants of mental health. However, there are aspects of the relationship between movement behavior and mental health that are not well understood, for example, the combined effects of all movement behaviors occurring throughout the daily 24-hour cycle, i.e., time in bed, SED, light-intensity physical activity, and moderate to vigorous physical activity (MVPA), on mental health. In addition, only a few well-designed workplace interventions for improving movement and mental health outcomes have been tested. Office workers often spend extensive amounts of time being sedentary and might particularly benefit from such interventions. The aims of this thesis were (1) to investigate cross-sectional associations between 24-hour movement behavior and mental health among office workers and (2) to evaluate the efficacy, acceptability, feasibility, and fidelity of two cluster randomized controlled trial (RCT) interventions for improving movement behavior and mental health using quantitative and qualitative methods.

    In Paper I, we investigated cross-sectional associations between 24-hour movement behavior and mental health outcomes (symptoms of depression and anxiety, burnout, mental wellbeing, and stress) among office workers (N=345-370). Movement behavior was measured using accelerometers and sleep diaries. Mental health outcomes were assessed using validated questionnaires. Only the proportion of time spent in MVPA, relative to all other behaviors, was positively associated with mental wellbeing. 

    Papers II-IV were based on a three-armed cluster RCT among office workers (N=263). During the 6-month intervention period, the iSED intervention group focused on reducing SED, and the iPA intervention group focused on increasing MVPA compared to a wait-list control group. The multi-level interventions were designed based on ecological models of health behavior, addressing the individual office workers as well as their physical, social, and organizational work environment. Paper II investigated intervention effects on accelerometer-measured 24-hour movement behavior and cardiorespiratory fitness. We considered overall 24-hour movement behavior and movement behavior during work versus non-work time. No intervention effects were found. Paper III was based on a qualitative study that was embedded in the RCT. It investigated the acceptability, feasibility, and fidelity of intervention components that addressed the individual, environmental and organizational level. Interviews and focus group discussions were performed with 38 key stakeholders after the 6-month intervention period. The study included office workers who received the interventions, health coaches who delivered counseling sessions, team leaders who were responsible for implementing group activities, and human resource and higher management staff who provided support at the organizational level. In general, the interventions were well appreciated, and components seemed to work as intended when delivered as intended. Many office workers experienced improvements in movement behavior and wellbeing and ascribed those to the interventions. Acceptability, feasibility, and fidelity of individual-level components were high but reduced for components depending on team leaders, mainly due to challenges associated with recruiting managers as team leaders and forming teams. Manager and team support were considered crucial for promoting more PA and less SED, yet many participants reported a lack of such support. Thus, identified challenges with these components might have reduced overall intervention efficacy. Paper IV investigated intervention effects on mental health outcomes (symptoms of depression or anxiety, mental wellbeing, and stress). In addition, we explored whether changes in mean PA intensity mediated or moderated intervention effects. The interventions improved mental wellbeing for the combined intervention groups and the iSED group but not for the iPA group compared to the control group. The interventions improved mean PA intensity, but mean PA intensity did not mediate intervention effects on any outcome. Mean PA intensity moderated intervention effects on mental wellbeing. Participants who reduced mean PA intensity reduced mental wellbeing compared to participants who did not change mean PA intensity. This highlights the importance of maintaining high levels of PA for mental wellbeing.

    This thesis contributes to existing knowledge by applying a rigorous investigation of cross-sectional associations between 24-h movement behavior and mental health among office workers and by conducting a comprehensive analysis of intervention effects. It offers valuable insights and considerations that may inform occupational health practitioners, employers, policy makers, and researchers and may contribute to developing future effective interventions.

    Improving movement behavior in office workers: effects of two multi-level cluster-RCT interventions on mental health2024Inngår i: BMC Public Health, E-ISSN 1471-2458, Vol. 24, nr 1, artikkel-id 127Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: We have previously reported on the design and efficacy of two cluster-randomized multi-level workplace interventions, attempting to decrease sedentary behavior (SED) or increase moderate to vigorous physical activity (MVPA) among office workers to improve mental health outcomes. The aim of this study was to investigate intervention effects on mental health outcomes, i.e., mental wellbeing, depression or anxiety symptoms, and stress immediately after the 6-month intervention period.

    Methods: Teams of 263 office workers were cluster-randomized to one of two interventions or a waitlist control group. The PA intervention (iPA) focused on increasing MVPA and the SED intervention (iSED) on reducing SED. Both multi-level interventions targeted individual office workers and their social, physical, and organizational work environment, incorporating counseling based on cognitive behavioral therapy and motivational interviewing. Mental health outcomes were assessed using validated questionnaires before and immediately after the intervention. Intervention effects were analyzed using linear mixed effects models.

    Results: Participants were mostly female and highly educated, with a mean age of 42 years and had favorable levels of mental health at baseline. Mental wellbeing improved for the iSED group (β = 8, 95% CI 1 to 15, p = 0.030) but not for the iPA group (β = 6, 95% CI -1 to 12, p = 0.072) compared to the control group. No effects were found for depression or anxiety symptoms or stress.

    Conclusions: The multi-level interventions improved mental wellbeing among this population of office workers, reaching statistical significance in the iSED group. The size of the effect can be regarded meaningful, considering favorable mental health and high PA level at baseline. Thus, workplace interventions that provide support on multiple levels appear to have potential for improving mental wellbeing, but not reducing ill-health variables, among healthy office workers. More research is needed to understand the mechanisms through which such improvements can be achieved and to identify the most effective intervention components.

    Effectiveness of two randomized and controlled multi-component interventions on 24-h movement behavior and mental health outcomes among office workers2022Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Background: To date it is unknown whether movement behavior change interventions among office workers are effective for improving mental health. Therefore, we designed a multi-component cluster RCT among office workers (N=263). One intervention group focused on reducing sedentary behavior (SED), the other on increasing moderate to vigorous physical activity (MVPA) compared to a wait-list control group. Based on ecological models of health behavior, intervention components addressed the individual (counseling using cognitive behavioral therapy (CBT) and motivational interviewing (MI)), the environmental (group activities such as lunch walks), and the organizational level (companies promoting the interventions internally). Primary outcomes were changes in accelerometer-measured and self-reported SED and MVPA, secondary outcomes were depression and anxiety symptoms, burnout, stress and mental well-being, assessed via validated, web- based questionnaires. Previous analyses using a compositional data analysis (CoDA) approach did not find intervention effects on 24-h movement behavior, i.e., SED, light intensity, moderate or vigorous physical activity. 

    Purpose: This study aims at investigating intervention effects on mental health, i.e., depression and anxiety symptoms, burnout, stress and mental well-being. Secondary aims are to describe those participants that achieved a significant change in accelerometer- and device-measured SED and MVPA in comparison to those that did not, and to investigate whether changes in movement behavior were associated with changes in mental well-being. 

    Methods: Linear mixed model analysis will be performed to analyze effects on mental health, according to the published study protocol. 

    Performing exploratory analyses, quartiles of participants, based on changes in MVPA and SED, will be described on demographic characteristics and compared across quartiles. Change change analyses will investigate whether changes in SED or MVPA are associated with changes in mental well-being. CoDA will be applied, taking the co-dependence of 24-h movement behaviors into account. 

    Implications: High sedentariness and sick-leave due to mental illness are challenges associated with office work. This RCT is the first among office workers that applies a multi-component approach to address several levels of health behavior, and that includes CBT and MI techniques. Results may inform occupational health and researcher efforts aiming at addressing the burden of sedentariness and its related consequences on mental health.

    Changing movement behavior for improving mental health among office workers: A qualitative study on acceptability, feasibility and fidelity of two RCT interventions2022Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Background: Behavior change research suggests that interventions addressing not only the individual, but also the environmental and organizational level might be more effective than those addressing only one. However, few RCTs have tried to change movement behavior among office workers with the aim of improving mental health outcomes, using multi-component interventions that address several levels. Above that, researchers seldomly assess acceptability, feasibility and fidelity of such complex interventions, even though they are considered important moderators of study outcomes. 

    Purpose: This study aims at determining aspects of intervention acceptability, feasibility and fidelity of two multi-component cluster RCT interventions among office workers (N=263). Specifically, we want to answer: 

    1. How did participants experience specific intervention components as facilitating or hindering a movement behavior change? 

    2. Which factors in the work and non-work context did participants experience as facilitating or hindering a movement behavior change? 

    3. Were intervention components implemented and perceived as intended? 

    Methods The interventions addressed the individual level (counseling sessions based on cognitive behavior therapy and motivational interviewing), the environmental level (e.g. walking meetings or lunch walks organized by team leaders) and the organizational level (participation during work time, employers encouraging participation). One intervention focused on reducing sedentary behavior, the other on increasing physical activity, compared to a wait-list control group. After completion of the 6-month intervention period, audio-recorded interviews and focus group discussions were performed with participants, health coaches delivering the counseling sessions, team leaders and Human Resource staff). Verbatim transcribed data will be analyzed using thematic analysis (Braun&Clarke 2006). An initial codebook based on a-priori themes of interest will be created. Two researchers will apply it to a subset of transcripts, in an inductive fashion whilst allowing for new themes to emerge. Once agreement on a final version of the codebook will be achieved, remaining transcripts will be analyzed accordingly. 

    Implications: We expect that the results of this study may help to understand and interpret the results of the quantitative effectiveness evaluations. This study may generate valuable knowledge that can inform future similar studies or workplace health promotion efforts and make their conduct more efficient.

    Effects of Two Randomized and Controlled Multi-Component Interventions Focusing On 24-Hour Movement Behavior among Office Workers: A Compositional Data Analysis.2021Inngår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 18, nr 8, artikkel-id 4191Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Intervention studies aiming at changing movement behavior have usually not accounted for the compositional nature of time-use data. Compositional data analysis (CoDA) has been suggested as a useful strategy for analyzing such data. The aim of this study was to examine the effects of two multi-component interventions on 24-h movement behavior (using CoDA) and on cardiorespiratory fitness among office workers; one focusing on reducing sedentariness and the other on increasing physical activity. Office workers (n = 263) were cluster randomized into one of two 6-month intervention groups, or a control group. Time spent in sedentary behavior, light-intensity, moderate and vigorous physical activity, and time in bed were assessed using accelerometers and diaries, both for 24 h in total, and for work and leisure time separately. Cardiorespiratory fitness was estimated using a sub-maximal cycle ergometer test. Intervention effects were analyzed using linear mixed models. No intervention effects were found, either for 24-h behaviors in total, or for work and leisure time behaviors separately. Cardiorespiratory fitness did not change significantly. Despite a thorough analysis of 24-h behaviors using CoDA, no intervention effects were found, neither for behaviors in total, nor for work and leisure time behaviors separately. Cardiorespiratory fitness did not change significantly. Although the design of the multi-component interventions was based on theoretical frameworks, and included cognitive behavioral therapy counselling, which has been proven effective in other populations, issues related to implementation of and compliance with some intervention components may have led to the observed lack of intervention effect.

    Associations between 24 h Movement Behavior and Mental Health in Office Workers.2020Inngår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 17, nr 17, artikkel-id E6214Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The associations between 24 h movement behavior, i.e., the way people distribute their time in different movement-related behaviors, on mental health are not well understood. This study applied a compositional data analysis approach to explore cross-sectional associations between device-measured moderate to vigorous physical activity (MVPA), light intensity physical activity (LIPA), sedentary behavior (SED), self-reported time in bed and mental health outcomes, i.e., depression or anxiety symptoms, burnout, mental wellbeing and stress, in office workers. ActiGraph accelerometers were worn for 24 h for at least 4 days to assess MVPA, LIPA, and SED. Sleep diaries were used in addition to identify time in bed. Analytic sample sizes for the different outcomes ranged from N = 345-370 participants. In this population of office workers with high levels of MVPA, the entire movement behavior composition was not associated to any of the mental health outcomes, but MVPA relative to all other behaviors was positively associated with mental wellbeing. This confirms the importance of MVPA for health relative to other movement-related behaviors.

    “It depends on the boss”: A qualitative study of multi-level interventions aiming at office workers’ movement behavior and mental health2023Inngår i: International Journal of Qualitative Studies on Health and Well-being, ISSN 1748-2623, E-ISSN 1748-2631, Vol. 18, nr 1, artikkel-id 2258564Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [en]

    Purpose: This embedded qualitative study explored the acceptability, feasibility, and fidelity of two multi-level RCT interventions among office workers, aiming at improving movement behaviour to enhance mental health and cognition. The interventions addressed the organizational, environmental, and individual level.

    Methods: Semi-structured interviews and focus group discussions were conducted with 38 stakeholders after completion of the interventions. Data were analysed using reflexive thematic analysis.

    Results: The interventions were well appreciated, and office workers attributed improvements in movement behaviour and wellbeing to the interventions. Especially the cognitive behavioural therapy (CBT) based counselling and free gym access were appreciated, feasible and delivered as planned. Participants described existing workplace norms as barriers to more activity, particularly for reducing sitting. Support from managers and team support were considered crucial components. However, delivering these components was difficult.

    Conclusions: The findings support the design of the multi-level interventions for changing movement behaviour. Results highlight the potential of CBT for this target group and the importance of manager and team support. Desired effects of similar multi-level interventions, including CBT, might be achieved in future studies that carefully address the issues with feasibility and acceptability and the resulting low fidelity of some intervention components that were identified in this study.

    Association of Sarcopenia and Its Defining Components with the Degree of Cognitive Impairment in a Memory Clinic Population.2023Inngår i: Journal of Alzheimer's Disease, ISSN 1387-2877, E-ISSN 1875-8908, Vol. 96, nr 2, s. 777-788Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Sarcopenia and cognitive impairment are two leading causes of disabilities.

    OBJECTIVE: The objective was to examine the prevalence of sarcopenia and investigate the association between sarcopenia diagnostic components (muscle strength, muscle mass, and physical performance) and cognitive impairment in memory clinic patients.

    METHODS: 368 patients were included (age 59.0±7.25 years, women: 58.7%), displaying three clinical phenotypes of cognitive impairments, i.e., subjective cognitive impairment (SCI, 57%), mild cognitive impairment (MCI, 26%), and Alzheimer's disease (AD, 17%). Sarcopenia was defined according to diagnostic algorithm recommended by the European Working Group on Sarcopenia in Older People. Components of sarcopenia were grip strength, bioelectrical impedance analysis, and gait speed. They were further aggregated into a score (0-3 points) by counting the numbers of limited components. Multi-nominal logistic regression was applied.

    RESULTS: Probable sarcopenia (i.e., reduced grip strength) was observed in 9.6% of the patients, and 3.5% were diagnosed with sarcopenia. Patients with faster gait speed showed less likelihood of MCI (odds ratio [OR]: 0.24, 95% confidence interval [CI]: 0.06-0.90) and AD (OR: 0.12, 95% CI: 0.03-0.60). One or more limited sarcopenia components was associated with worse cognitive function. After adjusting for potential confounders, the association remained significant only for AD (OR 4.29, 95% CI 1.45-11.92).

    CONCLUSION: The results indicate a connection between the sarcopenia components and cognitive impairments. Limitations in the sarcopenia measures, especially slow walking speed, were related to poorer cognitive outcomes. More investigationsare required to further verify the causal relationship between sarcopenia and cognitive outcomes.

    Har man inte motivation till träning eller tror man att man inte kan?: Sambandet mellan motivation och tilltro till förmåga till fysisk aktivitet2021Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Motivation och tilltro till förmåga har visat sig vara bra indikatorer vid främjandet av träning och vore av intresse att studera hos stillasittande, kontorsarbetande individer.

    Syfte

    Syftet med denna studie var att se sambandet mellan motivation och tron på den egna förmågan att utföra fysisk aktivitet i form av motion och träning. Utöver detta studerades även om eventuella skillnader existerar mellan könen.

    Metod

    Data som använts för denna studie kommer från den tre-delade randomiserad kontrollerad studien kallad ”Fysisk aktivitet och hjärnhälsa”. Totalt antal deltagare var 207 st kontorsarbetare i ålder 42±20 år varav 73,1% kvinnor. Utöver demografiska variabler användes datainsamlingen från enkäterna svensk version av Exercise Self-Efficacy Scale samt kort, svensk version av Behavioural Regulation in Exercise Questionnaire, fjärde utgåvan. 48 outliers med felaktiga värden togs bort samt 19 multivariata outliers med hjälp av Mahalanobis Distance. De statistiska analyser som användes för att besvara syftet varmultipel regressionsanalys samt MANOVA. För bearbetning av data användes IBM SPSS Statistics 27 med signifikansnivå p = 0,05. 

    Resultat

    Den multipla regressionsanalysen inkluderande samtliga motivationsvariabler visade sig statistiskt signifikant relaterad till utfallsvariabeln tilltro till förmåga, F(7,177) = 11,128, p < .001 och den förklarade variansen var 31 % (R² =.306). Signifikanta samband med tilltro till förmåga visades framför allt för inre och integrerad reglering med kontrollvariabler inkluderade (ß=.23 respektive ß=.26). MANOVA visade att skillnaden mellan könen inte var signifikant (F=2,19, p >.05; Wilk’s Λ = .948, partial η² = .052). 

    Slutsats

    Inre reglerade motivationsformer verkar ha ett positivt samband med tilltro till förmåga för träning hos kontorsarbetande, stillasittande svenskar. Mer yttre reglerade motivationsformer visar inte signifikanta värden på att en korrelation existerar med tilltro till förmåga. Inga signifikanta skillnader existerade mellan könen för både motivation och tilltro till förmåga till träning

    Working Memory and Reasoning Benefit from Different Modes of Large-scale Brain Dynamics in Healthy Older Adults.2018Inngår i: Journal of cognitive neuroscience, ISSN 0898-929X, E-ISSN 1530-8898, Vol. 30, nr 7, s. 1033-1046Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Researchers have proposed that solving complex reasoning problems, a key indicator of fluid intelligence, involves the same cognitive processes as solving working memory tasks. This proposal is supported by an overlap of the functional brain activations associated with the two types of tasks and by high correlations between interindividual differences in performance. We replicated these findings in 53 older participants but also showed that solving reasoning and working memory problems benefits from different configurations of the functional connectome and that this dissimilarity increases with a higher difficulty load. Specifically, superior performance in a typical working memory paradigm ( n-back) was associated with upregulation of modularity (increased between-network segregation), whereas performance in the reasoning task was associated with effective downregulation of modularity. We also showed that working memory training promotes task-invariant increases in modularity. Because superior reasoning performance is associated with downregulation of modular dynamics, training may thus have fostered an inefficient way of solving the reasoning tasks. This could help explain why working memory training does little to promote complex reasoning performance. The study concludes that complex reasoning abilities cannot be reduced to working memory and suggests the need to reconsider the feasibility of using working memory training interventions to attempt to achieve effects that transfer to broader cognition.

    Migraine, Cognitive Decline, and Dementia in Older Adults: A Population-Based Study.2022Inngår i: Journal of Alzheimer's Disease, ISSN 1387-2877, E-ISSN 1875-8908, Vol. 88, nr 1, s. 263-271Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: The potential impact of migraine on cognitive aging among older adults remains controversial.

    OBJECTIVE: To examine the relationship of migraine and subtypes with cognitive decline and dementia in an older Swedish population.

    METHODS: This population-based study included 3069 participants (age≥60) from the Swedish National study on Aging and Care in Kungsholmen, Stockholm. Baseline examination was conducted in 2001-2004, and participants were followed every 3 or 6 years until 2013-2016. Data were collected through face-to-face interviews, clinical examinations, laboratory tests, and linkage with registers. Global cognitive function was measured with the Mini-Mental State Examination (MMSE). Dementia was diagnosed according to the DSM-IV criteria. Migraine and subtypes were defined following the international classification system. Data were analyzed using logistic regression, Cox regression, and linear mixed-effects models.

    RESULTS: At baseline, 305 participants were defined with non-migraine headache and 352 with migraine. The cross-sectional analysis showed that the multivariable-adjusted odds ratio (95% confidence interval) of prevalent dementia was 0.49 (0.20-1.21) for migraine and 0.66 (0.26-1.66) for migraine without aura. The longitudinal analysis showed that the multivariable-adjusted hazard ratios of incident dementia associated with migraine and subtypes ranged 0.68-0.89 (p > 0.05). Furthermore, migraine and subtypes were not significantly associated with either baseline MMSE score or MMSE changes during follow-ups (p > 0.05). The nonsignificant associations did not vary substantially by age, APOEɛ4 allele, cerebrovascular disease, and antimigraine treatment (p for interactions > 0.05).

    CONCLUSION: This study shows no evidence supporting the associations of migraine and its subtypes with cognitive decline and dementia among older adults.

    Effects of Structured Lifestyle Education Program for Individuals With Increased Cardiovascular Risk Associated With Educational Level and Socioeconomic Area2021Inngår i: American Journal of Lifestyle Medicine, ISSN 1559-8276, E-ISSN 1559-8284, Vol. 15, nr 1, s. 28-38Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background.

    Differences in socioeconomic status contribute to inequalities in lifestyle habits and burden of noncommunicable diseases. We aimed to examine how the effects of a 1-year structured lifestyle education program associate with the participant's educational level and socioeconomic area (SEA) of residence.

    Methods.

    One hundred individuals (64% women) with high cardiovascular risk were included. Education level (nonuniversity vs university degree) was self-reported and SEA (low vs high) defined by living in different SEAs. Lifestyle habits and quality of life were self-reported, cardiovascular risk factors and Framingham 10-year cardiovascular disease risk were measured at baseline and after 1 year.

    Results.

    Sedentary behavior decreased in both nonuniversity degree and low SEA group over 1 year, with a significantly greater improvement in daily activity behavior in low- compared with high-SEA group. Abdominal obesity decreased significantly more in the nonuniversity compared with the university degree group. Cardiovascular risk and quality of life improved in all groups, however, with greater discrimination when using educational level as the dichotomization variable.

    Conclusion.

    The results are clinically and significantly relevant, suggesting that low socioeconomic status measured both as educational level and SEA are no barriers for changing unhealthy lifestyle habits and decreasing cardiovascular risk after participation in a lifestyle program.

    Test-retest reliability of a newly developed instrument for measurement of force production and speed in closed kinetic chain for upper extremity: Measurements on a group of athletes with cerebral palsy and a reference group2022Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Aim and research questions: The aim of this master thesis was to test for test-retest reliability for a newly developed force instrument (FI) and determine if a combined effect of trial, speed and resistance exist on the variable fraction effective force (FEF) for a group of athletes with cerebral palsy (CP-group) and a reference group (AB-group). 

    1. What is the intraclass correlation coefficient on maximum velocity measured on two occasions with the FI for a CP-group and an AB-group?

    2. What is the intraclass correlation coefficient on FEF for a flexion movement measured on two occasions for an AB-group?

    3. Is there an interaction effect of; a) trial and group, b) trial, speed and group, c) trial, resistance and group and d) trial, speed, resistance and group, on the variable FEF for a flexion movement for a CP-group and an AB-group?

     

    Method: This master thesis was an experimental cross-sectional study with a test-retest design. Data collection took place in Stockholm and in Elche (Spain), 2022. Participants visited the BMC laboratory at two occasions. Participants completed tasks with their least impaired arm (CP-group) or dominant arm (AB-group) in a horizonal movement at different resistances and speeds on the FI. Maximum velocity together with force in 3 directions was registered. FEF was calculated from the three forces. ICC on Vmax for both groups and FEF for the AB-group was conducted together with a mixed-design ANOVA on de independent variables trial, group, speed and resistance on the dependent variable FEF. 

     

    Results: 18 participants in the CP-group and 20 participants in the AB-group was included for statistical analysis. The ICC on Vmax was .944 for the CP-group and .804 for the AB-group. The mean ICC for FEF was .644 for the AB-group. Using a mixed-design ANOVA concluded that there was no significant interaction effect on trial, group, speed and resistance, F(4) =2.069, p=.088, nor in any of the other combinations. 

     

    Conclusion: The newly developed FI shows good test-retest reliability for both groups and could be used for measurements of arm coordination. Further studies are needed to further evaluate reliability of the instrument.

    Samband mellan stillasittande, fysisk aktivitet och förlossningsdepression.: en tvärsnittsstudie2023Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syfte och frågeställningar

    Syftet med studien var att undersöka om det fanns ett samband mellan stillasittande beteenden och högre indikationer på förlossningsdepression. Syftet med studien var även att se om det fanns ett samband mellan fysisk aktivitet på måttlig- eller hög intensitet och lägre indikationer på förlossningsdepression.

    Finns det ett samband mellan stillasittande beteende under postpartumtiden och högre indikation på förlossningsdepression? 

    Visar fysisk aktivitet på måttlig intensitet under postpartumtiden samband med lägre indikation på förlossningsdepression? 

    Visar fysisk aktivitet på hög intensitet under postpartumtiden samband med lägre indikation på förlossningsdepression? 

    Metod

    Studien är en icke-experimentell kvantitativ tvärsnittsstudie. Studiens deltagare fick uppskatta tiden för stillasittande och fysisk aktivitet på måttlig- och hög intensitet via en enkätundersökning. Deltagarna fick även fylla i Edinburgh Postnatal Depression Scale (EPDS) för att mäta indikationer på förlossningsdepression. Deltagarna i studien var enbart kvinnor som var över arton år och fött sitt första barn för 6–8 veckor sedan vaginalt. Data från enkäterna (N=117) analyserades i IBM® SPSS® Statistics 29 (SPSS). Enkel linjär regression användes för att analysera sambandet mellan indikationer på förlossningsdepression och stillasittande samt fysisk aktivitet på måttlig- och hög intensitet.

    Resultat

    Signifikant (0,027) samband fanns mellan fysisk aktivitet på måttlig intensitet under postpartumtiden och indikationer på förlossningsdepression. Samband mellan stillasittande och fysisk aktivitet på hög intensitet under postpartumtiden visade inget signifikant samband.

    Slutsats

    Vidare forskning behövs för att verifiera sambandet mellan fysisk aktivitet på måttlig intensitet och indikationer på förlossningsdepression. Samband mellan indikationer på förlossningsdepression och stillasittande beteende samt fysisk aktivitet på hög intensitet behöver studeras vidare för att se eventuellt signifikant samband.

    "We are all the same": En kvalitativ studie om hälsa bland ungdomar med rörelsehinder i Kenya och Sverige2024Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syfte och frågeställning

    Syftet med denna studie är att undersöka eventuella skillnader av hur ungdomar medrörelsehinder upplevs, hur de anser att de blir behandlade och hur de blir påverkade av sitt rörelsehinder beroende på om de är födda i Sverige eller Kenya.

    - Hur blir ungdomar med rörelsehinder påverkade av sitt handikapp?

    - Hur upplever ungdomar med rörelsehinder att de blir behandlade?

    - Hur ser omgivningen på ungdomar med rörelsehinder?

    Metod

    Studien har använt sig av intervjuer för att dyka på djupet och undersöka upplevelser av attleva med ett rörelsehinder. Totalt har 5 ungdomar intervjuats och tre vuxna som jobbar medungdomar som har rörelsehinder i olika utsträckningar. Intervjuerna har utförts i landet somungdomarna och de vuxna befunnit sig i, de har skett enskilt och i Kenya var en tolknärvarande för att underlätta intervjun. Det har skapats en intervjuguide (bilaga 1 och 2) utifrån frågeställningarna som följts genom intervjuerna, följdfrågor har förekommit i de måndet varit intressant och lämpligt för att ge utrymme till utvecklade svar.

    Resultat

    Studien har visat på skillnader i upplevelser och stigmatisering i de olika länderna.Ungdomarna i de båda länder har liknande upplevelser men de vuxnas upplevelser skiljer sig åt. I Kenya finns en tydlig stigmatisering och landet har inte kommit lika långt i sitt arbete förfunktionsnedsatta. Sverige är ett mer välutrustat land men har problem inom välfärd och det finns även en stigmatisering om att rörelsehindrade är mindre intellektuella än personer utanr örelsehinder.

    Slutsats

    I helhet visar studien på skillnader mellan länderna men även likheter. Båda länder harsvårigheter när det kommer till funktion av rörelsehjälpmedel i form av väder och infrastruktur. Båda grupper visar på stigmatisering i respektive länder trots att denna stigmatisering skiljer sig åt. Den största skillnaden ses i ungdomarnas syn på sin omgivning och sitt eget rörelsehinder. Ungdomarna i Kenya berättade att de inte ansåg att deras rörelsehinder påverkade ungdomarna mycket, de berättade även att omgivningen både på barnhemmet och i respektive byar inte såg ungdomarna som annorlunda. Detta skiljer sig från de vuxnas intervjuer om hur personer med rörelsehinder blir behandlade och kan bero på deras omgivning och förutsättningar de får från barnhemmet.

    Finns det samband mellan stress och fysisk aktivitet under olika perioder hos högskole- och universitetsstudenter?: en tvärsnittsstudie2022Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syfte. Syftet med studien var att undersöka om det fanns något samband samt skillnad mellan högskolestudenters och universitetsstudenters fysiska aktivitet och stress mellan vanliga studieperioder (period 1) och studieperioder med tentor (period 2). Studien granskade även om det förelåg ett samband mellan stress och fysisk aktivitet för kvinnor och om det fanns samband mellan stress och fysisk aktivitet hos män. Hypotesen var att högre upplevd stress  skulle leda till lägre fysisk aktivitet och att deltagarna skattade högre stressnivå under period 2 som resulterade i lägre fysisk aktivitet. Hypotesen var också att det förekom en skillnad i upplevd stress mellan könen.   

    Metod. I studien så användes en subjektiv, kvantitativ metod med elektroniska enkäter som skickades ut till 20 stycken olika högskolor och universitet samt delades vidare via sociala medier, vänner och bekanta. Enkäten var konstruerad i tre olika delar. Första delen innehöll allmänna frågor om studiepopulationen. De andra två delarna (period 1 och period 2) bestod av frågor om fysiska aktivitetsvanor och upplevd stress. Fysisk aktivitet skattades genom fem frågor från enkäten GIH:s-hälsotest. För att mäta stress användes Perceived Stress Scale (PSS-10). Frågorna var utformade med skalor från lägst till högst. Frågorna som användes upprepades för period 1 och period 2 i enkäten, så att en jämförelse kunde analyseras mellan perioderna. Det vill säga att samma frågor besvarades två gånger men vid ett tillfälle. 

    Resultat. Totalt utförde 54 deltagare enkäten varav 43 var kvinnor och 11 var män. Genomsnittsåldern var ≈ 30 år. Analyserna visade inget signifikant samband mellan stress och fysisk aktivitet för varken P1 eller P2 eller uppdelat mellan kvinnor och män. Däremot fanns en indikation på ett icke-signifikant negativt samband vilket visade på en riktning att när stressen ökade så minskade den fysiska aktiviteten och nivån av stillasittandet steg. Det var signifikanta skillnader mellan de två perioderna, där det visades att medelvärdena i stress (p= <0.001) och stillasittande (p= <0.001) ökade och fysisk aktivitet minskade (p= 0.002 - 0.017) under period 2 (närliggande tenta). Under period 1 visade ett signifikant värde (p =0.021) att kvinnorna (17,5土7,1) skattade högre stress än männen (11,7土7,5) och att kvinnorna (5.3土2.5) skattade lägre måttlig FA än männen (5.4土2.9).

    Slutsats. Inga signifikanta samband kunde urskiljas. Däremot visade resultatet en ökad stressnivå hos studenterna under period 2 (närliggande tenta) jämfört med period 1. Förslagsvis bör skolor påbörja med insatser som kan minska stressnivån hos studenter vid närliggande tenta. Högskolor och universitet kan även undervisa i fysisk aktivitet och dess hälsofördelar.

    Röster från en stängd idrottsvärld: En kvalitativ studie om Coronakrisens effekter på föreningsidrotten i två Stockholmskommuner2021Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syfte & frågeställningar Syftet med denna studie var att undersöka hur Coronakrisens effekter påverkat föreningsaktiva ungdomar i olika socioekonomiska områden. Vi har arbetat utifrån två frågeställningar. Vad händer när föreningsidrotten tas bort från barn och unga? Finns det skillnader i hur individer från olika so- cioekonomiska områden hanterat Coronakrisen?

    Metod I syfte att få en ökad förståelse om hur föreningsaktiva människor hanterat en kris använde vi oss av en kvalitativ studiemetod med en induktiv ansats. Datainsamlingen skedde via semistrukturerade intervjuer. Urvalet var föreningsaktiva barn och ungdomar från två olika socioekonomiskt starka områden. Totalt intervjuades sex personer, tre bosatta i Danderyd kommun och tre i Södertälje kommun. Intervjuerna transkriberades och analyserades genom en innehållsanalys där tre teman identifierades.

    Resultat Bortfallet av föreningsidrotten upplevs ha haft en fysiskt och psykisk inverkan på barn och unga, med färre träningstillfällen och minskad motivation. Däremot verkar föreningsaktiva vara tränings medvetna och har en bra förståelse för tränings substitut. Dock uppfattas det som att idrottsföre- ningen har en vital roll i barn och ungas sätt att hitta dessa alternativa träningsmetoder. Vi kunde inte identifiera socioekonomiska skillnader som en faktor till huruvida dessa ungdomar hanterat omställningen p.g.a. pandemin på olika sätt. Däremot uppfattades det som att idrottsföreningarna i Södertälje har erbjudit sina utövare ett större stöd i form av alternativa föreningsaktiviteter genom digitala träningspass, uteträning och träningsscheman.

    Slutsats Det behöver göras mer insatser och forskning för att förstå komplexiteten i bortfallet av ungdomsid- rotten och dess påverkan i olika socioekonomiska områden. Det är ett högaktuellt ämne som kräver mer forskning. En enkätundersökning i större omfattning gällande hur pandemin och dess restrik- tioner påverkat idrottsföreningar för ungdomar och hur föreningarna tvingats ställa om, minska eller justera antalet träningstillfällen hade varit bra för att få en tydligare inblick i just denna fråga.

    Är svenska tävlingsryttare passionerade?: En kvantitativ enkätstudie om passion och medveten närvaro hos svenska tävlingsryttare2023Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Aim and research questions: The aim of this survey study was to increase the understanding of motivational factors in Swedish competition riders by investigating passion, mindfulness, and age. Three research questions were central for this study:1. To which extent do Swedish competition riders exhibit harmonious passion and obsessive passion? 2. To which extent do Swedish competition riders exhibit mindfulness? 3. Are there any correlations between harmonious passion, obsessive passion, age, and mindfulness in Swedish competition riders? Method: This study used a quantitative approach with a cross-sectional study design and survey as data collection method. The study had 236 participants who were Swedish riders competing in either dressage or jumping at no lower than 2* (regional) level. Participation was voluntary, and the survey was answered anonymously. The data was collected during a period of six weeks. The data was processed using descriptive statistics, correlation analysis and multiple linear regression analysis. Results: Participants showing higher levels of harmonious passion also showed higher levels of obsessive passion and were more able to refocus. Participants showing higher levels of obsessive passion were loss able to refocus. Riders exhibiting higher levels of harmonious passion also felt more aware regardless of age and level of obsessive passion. Conclusion: The conclusion for this study was that according to passion theory, Swedish competition riders can be described as motivated athletes. The results indicate that harmoniously passionate riders are more mindful and accepting, while obsessively passionate riders are more self-judgmental.

    Attityder till och upplevelser av en hälsokampanj2022Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Syfte och frågeställning

    Denna studie har till syfte att undersöka attityder till och upplevelser av hälsokampanjer hos boende i ett mångkulturellt område med låg socioekonomisk status. Frågeställningarna var: 

    -       Vilka attityder har de boende i ett mångkulturellt bostadsområde till en hälsokampanj med motiverande budskap för fysisk aktivitet?

    -       Hur upplever de boende en hälsokampanj i deras bostadsmiljö? 

    Metod

    För att besvara syftet och frågeställningarna har en kvalitativ metod med semistrukturerade intervjuer använts. 15 personer rekryterades genom bekvämlighets- och snöbollsurval i ett område med låg socioekonomisk status. Deltagarna var mellan 18–77 år. Intervjuerna transkriberades och analyserades därefter genom induktiv innehållsanalys enligt Graneheim och Lundman (2004).

    Resultat

    Innehållsanalysen resulterade i fyra huvudkategorier; positiva attityder, negativa attityder, behov samt hinder. Huvudresultaten var att 1) Hälsokampanjer med motiverande budskap ses som uppmuntran och en bra påminnelse till fysisk aktivitet. 2) Lågt förtroende för avsändaren skapar negativ attityd. 3) Hälsokampanjen behöver vara begriplig, valfri och meningsfull för deltagaren. 4) Både inre och yttre hinder försvårar möjligheten till att delta. 

    Slutsats

    Den här studien fann både positiva och negativa attityder samt olika upplevelser av behov och hinder till deltagande vid en hälsokampanj med motiverande budskap för fysisk aktivitet bland boende i ett mångkulturellt område med låg socioekonomisk status. Vidare visar resultatet att det fanns behov av att göra hälsokampanjen begriplig samt kunskap om varför och meningen med att delta hos deltagarna. Detta kan behöva prioriteras vid utformandet och genomförandet av en liknande hälsokampanj.
