    Physical activity for persons with obesity—a health project reported2008Inngår i: Forum on Public Policy Online, ISSN 1938-9809, Vol. 4, nr SpringArtikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In public health contexts, increased physical activity habits and fitness (aerobic and strength capacities) are positively related for promoting health and preventing  and treating common diseases/problems, including obesity and overweight. A strongly graded inverse association between physical activity and obesity has been shown both for adults and children. However, a lower mortality risk has been shown for those with greater weight but good aerobic capacity than for those of recommended weight but less fit. On the basis of a health project with physical activity for persons with or without obesity, the paper discusses evidence-based methods for promoting physical activity. General guidelines for the amount of physical activity for persons are described, as are the numerous physiological and medical advantages of physical activity. The economic benefits are also illustrated. The paper exemplifies methods of measuring physical activity habits and physical fitness. These two factors must be observed when showing improvements in public-health contexts, including groups with obesity.

    Improved Physical Capacity in a Project with Guided Physical Activity for Persons with Depression or Anxiety.2010Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Background: Higher physical capacity is correlated with increased health. Knowledge in this area regarding psychiatric diseases is sparse. 

    Purpose: The aim was to study aerobic and several strength capacities in a physical activity project for persons with depression or anxiety.

    Methods: Eighty-four persons (56 women and 28 men) with depression or anxiety were recruited from psychiatric out-patient clinics in Stockholm. Their mean age and BMI was 46 (21-80) years and 26 (17-41) kg/m2, respectively. 50% were sick-listed. 50% had BMI>25. Aerobic and strength tests were chosen by each subgroup´s project leaders. Directed physical activity was given, in groups 10-15, 1 hour twice/week during 8-12 weeks.

    Results: Significant changes (p<0.05, of all n=84) between pre- and post tests were seen in submaximal cycle test (11% enhanced values, n=56) and distance of 6 minutes walk test (16%, n=15) as well as in strength tests for the back for the back (i.e. time in static horizontal belly-back, 40%, n=44), abdominal and hip flexors (i.e. number of hip flexion sit-ups, 45%, n=38), leg (i.e. standing with 90O in hips and knees, 48%, n=56) and arm with shoulder muscles (i.e. number of raising weights alternately with the arms, 46%, n=32). Hand grip tests, BMI or blood pressure values did not change significantly.

    Conclusions: Directed 8-12 weeks physical activity programs can improve physical fitness in individuals with depression or anxiety.

    Reexamination of Accelerometer Calibration with Energy Expenditure as Criterion: VO2net Instead of MET for Age-Equivalent Physical Activity Intensity.2019Inngår i: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 19, nr 15, artikkel-id E3377Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Accelerometer calibration for physical activity (PA) intensity is commonly performed using Metabolic Equivalent of Task (MET) as criterion. However, MET is not an age-equivalent measure of PA intensity, which limits the use of MET-calibrated accelerometers for age-related PA investigations. We investigated calibration using VO2net (VO2gross - VO2stand; mL⋅min-1⋅kg-1) as criterion compared to MET (VO2gross/VO2rest) and the effect on assessment of free-living PA in children, adolescents and adults. Oxygen consumption and hip/thigh accelerometer data were collected during rest, stand and treadmill walk and run. Equivalent speed (Speedeq) was used as indicator of the absolute speed (Speedabs) performed with the same effort in individuals of different body size/age. The results showed that VO2net was higher in younger age-groups for Speedabs, but was similar in the three age-groups for Speedeq. MET was lower in younger age-groups for both Speedabs and Speedeq. The same VO2net-values respective MET-values were applied to all age-groups to develop accelerometer PA intensity cut-points. Free-living moderate-and-vigorous PA was 216, 115, 74 and 71 min/d in children, adolescents, younger and older adults with VO2net-calibration, but 140, 83, 74 and 41 min/d with MET-calibration, respectively. In conclusion, VO2net calibration of accelerometers may provide age-equivalent measures of PA intensity/effort for more accurate age-related investigations of PA in epidemiological research.

    Re-examination of accelerometer data processing and calibration for the assessment of physical activity intensity.2019Inngår i: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 29, nr 10, s. 1442-1452Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This review reexamines use of accelerometer and oxygen uptake data for assessment of activity intensity. Accelerometers capture mechanical work, while oxygen uptake captures the energy cost of this work. Frequency filtering needs to be considered when processing acceleration data. A too restrictive filter attenuates the acceleration signal for walking and, to a higher degree, for running. This measurement error affects shorter (children) more than taller (adults) individuals due to their higher movement frequency. Less restrictive filtering includes more movement related signals and provide measures that better capture mechanical work, but may include more noise. An optimal filter cut-point is determined where most relevant acceleration signals are included. Further, accelerometer placement affects what part of mechanical work being captured. While the waist placement captures total mechanical work and therefore contributes to measures of activity intensity equivalent by age and stature, the thigh and wrist placements capture more internal work and do not provide equivalent measures. Value calibration of accelerometer measures is usually performed using measured oxygen uptake with the metabolic equivalent of task (MET) as reference measure of activity intensity. However, the use of MET is not stringent and is not a measure of activity intensity equivalent by age and stature. A candidate measure is the mass-specific net oxygen uptake, VO2 net (VO2 tot - VO2 stand). To improve measurement of physical activity intensity using accelerometers, research developments are suggested concerning processing of accelerometer data, use of energy expenditure as reference for activity intensity, and calibration procedure with absolute versus relative intensity.

    Abstract [sv]

    Sammanfattning

    Fysisk aktivitet ger fysiska och mentala hälsovinster hos barn och ungdomar.

    Mognads- och tillväxtprocesserna hos barn och ungdomar påverkar en rad fysiska, mentala och sociala kapaciteter och förmågor. Vid rekommendation av fysisk aktivitet bör hänsyn tas till detta och individuella intressen.

    Alla barn och ungdomar mellan 6 och 17 år rekommenderas minst 60 minuters daglig fysisk aktivitet av främst aerob karaktär. Muskelstärkande och skelettstärkande aktiviteter bör ingå tre gånger i veckan. Hos barn från 0–5 år ska daglig fysisk aktivitet uppmuntras och underlättas.

    Barn och ungdomar som inte kan nå upp till rekommendationerna på grund av sjukdom eller funktionsnedsättning bör vara så aktiva som tillståndet medger.

    Individuella råd för anpassad regelbunden fysisk aktivitet bör ges.

    Barn och ungdomar med övervikt och fetma kan uppnå positiva hälsoeffekter av fysisk aktivitet avseende till exempel blodfetter och insulinkänslighet även om vikten är oförändrad. Konditionshöjande fysisk aktivitet har tydligast effekt, och i kombination med kostförändringar är effekterna större.

    Hos barn och ungdomar med astma bör en noggrann analys av ansträngningsutlösta besvär göras. Astman ska vara välreglerad och anpassad information och kunskap ska ges för att trygga den unge och främja fysisk aktivitet.

    Fysisk aktivitet utgör en del av behandlingen vid depression hos barn och ungdomar.

    Barn och ungdomars hälsa tycks kunna påverkas negativt av långvarigt stillasittande. För närvarande finns dock inte tillräckligt med vetenskapligt stöd för att ge en evidensbaserad rekommendation angående begränsning av stillasittande i den här åldersgruppen.

    Rekommendationer om fysisk aktivitet för barn och ungdomar2015Inngår i: FYSS 2015, Stockholm: Yrkesföreningar för Fysisk Aktivitet (YFA) , 2015Kapittel i bok, del av antologi (Annet (populærvitenskap, debatt, mm))
    Abstract [sv]

    En rimlig fråga är varför barn och unga är speciella när det gäller hälsoeffekter av fysisk aktivitet. Många av de påvisade och kända effekterna av fysisk aktivitet är likartade oavsett ålder, men i vissa fall finns det anledning att lyfta fram vad som är specifikt för barn och unga.

    Mognads- och tillväxtprocesserna, som i princip pågår fram till cirka 18–20 års ålder, är ofta orsaken till de skillnader som finns. En rad kapaciteter och förmågor, till exempel syreupptagningsförmåga, muskelstyrka, koordination och motorik samt mentala aspekter utvecklas över tid. En konsekvens av detta är att det är svårt att med precision utvärdera effekter av träning hos en ung individ, och att på ett korrekt och meningsfullt sätt särskilja dessa från mognad och tillväxt. En annan faktor är ökande kroppsstorlek, vilken medför att gränser för övervikt och fetma varierar mellan könen och med ålder upp till cirka 18 år. Att på ett korrekt sätt värdera effekter av insatser mot övervikt hos en växande individ kräver särskilda överväganden.

    Validity of the revised Ekblom Bak cycle ergometer test in adults.2016Inngår i: European Journal of Applied Physiology, ISSN 1439-6319, E-ISSN 1439-6327, Vol. 116, nr 9, s. 1627-1638Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: To further develop the Ekblom Bak-test prediction equation for estimation of VO2max from submaximal cycle ergometry.

    METHODS: The model group (117 men and 100 women, aged 48.3 ± 15.7 and 46.1 ± 16.8 years, VO2max 46.6 ± 11.1 and 40.4 ± 9.6 mL kg(-1) min(-1), respectively) and the cross-validation group (60 men and 55 women, aged 40.6 ± 17.1 and 41.6 ± 16.7 years, VO2max 49.0 ± 12.1 and 43.2 ± 8.9 mL min(-1) kg(-1), respectively) performed 4 min of cycling on a standard work rate (30 W) directly followed by 4 min on a higher work rate. Heart rate (HR) at each work rate was recorded. Thereafter, participants completed a graded maximal treadmill test for direct measurement of oxygen uptake. The new prediction equation was cross-validated and accuracy compared with the original Ekblom Bak equation as well as by the Åstrand test method.

    RESULTS: The final sex-specific regression models included age, change in HR per-unit change in power (ΔHR/ΔPO), the difference in work rates (ΔPO), and HR at standard work rate as independent variables. The adjusted R (2) for the final models were 0.86 in men and 0.83 in women. The coefficient of variation (CV) was 8.7 % and SEE 0.28 L min(-1). The corresponding CV and SEE values for the EB-test2012 and the Åstrand tests were 10.9 and 18.1 % and 0.35 and 0.48 L min(-1), respectively.

    CONCLUSION: The new EB-test prediction equation provides an easy administered and valid estimation of VO2max for a wide variety of ages (20-86 years) and fitness levels (19-76 mL kg(-1) min(-1)).

    Hälsoprojekt med ledarledd fysisk aktivitet för äldre2012Konferansepaper (Annet vitenskapelig)
    Abstract [sv]

    Bakgrund och syfte. Syftet med hälsoprojektet under 8-12 veckor för äldre är att ge ledarledd fysisk aktivitet 2 gånger/vecka samt att utvärdera upplevd hälsa, förändring av livsstilssvanor samt fysisk kapacitet. Hälsoprojektet är ett fortlöpande samarbete mellan Solna stad och Gymnastik- och idrottshögskolan (GIH) och utförs under vårterminerna sedan ett flertal år.

    Metod. Individerna anmäler sitt deltagande själva. Det kostnadsfria hälsoprojektet utförs inom undervisningen i Folkhälsa i regi av GIH-studenter under handledning av verksamhetschefen i Solna stad och lärare/läkare på GIH. Den ledarledda fysiska aktiviteten utgörs primärt av stavgång, motionsgymnastik, vattengymnastik samt styrketräning. Initialt och i slutet av perioden besvarar deltagarna en hälsoenkät angående upplevd hälsa och livsstilsvanor om fysisk aktivitet, kost, sömn, rökning och alkohol samt utför några olika fysiologiska tester i samband med ett hälsosamtal.

    Resultat. Exempel på sammanställda resultat ges här för de 117 äldre som fullföljde hela projektet under en vårtermin (för kvinnorna var antalet samt medelvärden för ålder och BMI 99, 74år och 26 respektive för männen 18, 73år och 25). Efter avslutat projekt sågs för gruppen som helhet generellt en signifikant förbättrad upplevd fysisk och mental hälsa, kondition och styrka i buk-, ben- och armmuskulatur. För kvinnorna observerades även en ökad balansförmåga och uthållighet i ryggmusklerna. Enkätfrågorna angående fysiska aktivitetsvanor och stillasittande visade på, efter avslutat projekt, en förändring till en mer aktiv livsstil.

    Slutsats/Diskussion. Således kan utvärderade 8-12 veckors hälsoprojekt med ledarledd fysisk aktivitet för äldre bidra till förbättrad upplevd hälsa, ökade fysiska aktivitetsvanor, minskat stillasittande och bättre fysiska kapaciteter såsom kondition, styrka och balans som är positivt korrelerade till ökad livslängd och minskad förekomst av en mängd olika folksjukdomar och skador. Fler projekt och studier behövs framöver med ytterligare uppföljningar, jämförelser och för att vidareutveckla olika fysiologiska tester och andra hälsoparametrar som kan ha positiva samband med ökad hälsa.

    Response of severely obese children and adolescents to behavioral treatment.2012Inngår i: Archives of Pediatrics & Adolescent Medicine, ISSN 1072-4710, E-ISSN 1538-3628, Vol. 166, nr 12, s. 1103-1108Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES:

    To investigate whether the degree of obesity predicts the efficacy of long-term behavioral treatment and to explore any interaction with age.

    DESIGN:

    A 3-year longitudinal observational study. Obese children were divided into 3 age groups (6-9, 10-13, and 14-16 years) and also into 2 groups (moderately obese, with a body mass index [BMI]-standard deviation [SD] score [or z score] of 1.6 to <3.5, and severely obese, with a BMI-SD score of ≥3.5).

    SETTING:

    National Childhood Obesity Center, Stockholm, Sweden.

    PARTICIPANTS:

    Children 6 to 16 years of age who started treatment between 1998 and 2006.

    INTERVENTION:

    Behavioral treatment of obesity.

    MAIN OUTCOME MEASURE:

    Change in BMI-SD score during 3 years of treatment; a reduction in BMI-SD score of 0.5 units or more was defined as clinically significant.

    RESULTS:

    A total of 643 children (49% female children) met the inclusion criteria. Among the youngest moderately obese children, 44% had a clinically significant reduction in BMI-SD score (mean reduction, -0.4 [95% CI, -0.55 to -0.32]). Treatment was less effective for the older moderately obese children. Twenty percent of children who were 10 to 13 years of age and 8% of children who were 14 to 16 years of age had a reduction in BMI-SD score of 0.5 units or more; 58% of the severely obese young children showed a clinically significant reduction in BMI-SD score (mean reduction, -0.7 [95% CI, -0.80 to -0.54]). The severely obese adolescents showed no change in mean BMI-SD score after 3 years, and 2% experienced clinically significant weight loss. Age was found to be a predictor of a reduction in BMI-SD score (odds ratio, 0.68 units per year [95% CI, 0.60-0.77 units per year]).

    CONCLUSIONS:

    Behavioral treatment was successful for severely obese children but had almost no effect on severely obese adolescents.

    Importance of age for 3-year continuous behavioral obesity treatment success and dropout rate.2012Inngår i: Obesity Facts, ISSN 1662-4025, E-ISSN 1662-4033, Vol. 5, nr 1, s. 34-44Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Abstract

    Objective: To assess whether first year weight loss, age, and socioeconomic background correlate with the success rate of continuous long-term behavioral obesity treatment. Methods: In a 3-year longitudinal study, obese children (n = 684) were divided into three groups based on age at the start of treatment, age 6-9 years, 10-13 years, and 14-16 years. Results: The mean BMI standard deviation score (BMI-SDS) decline was age-dependent (p = 0.001), independently of adjustment for missing data: -1.8 BMI-SDS units in the youngest, -1.3 in the middle age group, and -0.5 in the oldest age group. SES and parental BMI status did not affect the results. 30% of the adolescents remained in treatment at year 3. There was only a weak correlation between BMI-SDS change after 1 and 3 years: r = 0.51 (p < 0.001). Among children with no BMI-SDS reduction during year 1 (n = 46), 40% had a clinically significantly reduced BMI-SDS after year 3. Conclusion: Behavioral treatment should be initiated at an early age to increase the chance for good results. Childhood obesity treatment should be continued for at least 3 years, regardless of the initial change in BMI-SDS. Copyright © 2012 S. Karger GmbH, Freiburg.

    Physical inactivity and smoking after myocardial infarction as predictors for readmission and survival: results from the SWEDEHEART-registry.2019Inngår i: Clinical Research in Cardiology, ISSN 1861-0684, E-ISSN 1861-0692, Vol. 108, nr 3, s. 324-332Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Physical activity (PA) and smoking cessation are included in the secondary prevention guidelines after myocardial infarction (MI), but they are still underutilised. This study aims to explore how PA level and smoking status (6-10 weeks post-MI) were associated with 1-year readmission and mortality during full follow-up time, and with the cumulative 5-year mortality.

    METHODS: A population-based cohort of all hospitals providing MI-care in Sweden (SWEDEHEART-registry) in 2004-2014. PA was expressed as the number of exercise sessions of ≥ 30 min in the last 7 days: 0-1 (low), 2-4 (medium) and 5-7 (high) sessions/week. Individuals were categorised as smokers, former smokers or never-smokers. The associations were analysed by unadjusted and adjusted logistic and Cox regressions.

    RESULTS: During follow-up (M = 3.58 years), a total of 1702 deaths occurred among 30 644 individuals (14.1 cases per 1000 person-years). For medium and high PA, the hazard ratios (HRs) for mortality were 0.39 and 0.36, respectively, compared with low PA. For never-smokers, the HR was 0.45 and former smokers 0.56 compared with smokers. Compared with low PA, the odds ratios (ORs) for readmission in medium PA were 0.65 and 0.59 for CVD and non-CVD causes, respectively. For high PA, the corresponding ORs were 0.63 and 0.55. The association remained in adjusted models. There were no associations between smoking status and readmission.

    CONCLUSIONS: The PA level and smoking status are strong predictors of mortality post-MI and the PA level also predicts readmission, highlighting the importance of adherence to the secondary prevention guidelines.

    Sex- and age-specific associations between cardiorespiratory fitness, CVD morbidity and all-cause mortality in 266.109 adults.2019Inngår i: Preventive Medicine, ISSN 0091-7435, E-ISSN 1096-0260, Vol. 127, artikkel-id 105799Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim was to investigate sex- and age-specific associations between cardiorespiratory fitness, all-cause and cause-specific mortality, and cardiovascular disease (CVD) morbidity. 266.109 participants (47% women, 18-74 years) free from CVD, participating in occupational health service screenings in 1995-2015 were included. CRF was assessed as estimated maximal oxygen consumption (estVO2max) using a submaximal cycle test. Incident cases of first-time CVD event and death from any cause were ascertained through national registers. There were 4244 CVD events and 2750 cases of all-cause mortality during mean 7.6 years follow-up. Male gender, higher age and lower estVO2max were associated with higher all-cause mortality and CVD morbidity incidence rates. Risk reductions with increasing estVO2max were present in all age-groups of men and women. No obvious levelling off in risk was identified in the total cohort. However, women and older age-groups showed no further reduction in higher aggregated estVO2max levels. CVD specific mortality was more associated with estVO2max compared to tumor specific mortality. The risk for all-cause mortality and CVD morbidity decreased by 2.3% and 2.6% per increase in 1 ml·min-1·kg-1 with no significant sex-differences but more pronounced in the three lower estVO2max categories for all-cause mortality (9.1%, 3.8% and 3.3%, respectively). High compared to lower levels of estVO2max was not related to a significantly elevated mortality or morbidity. In this large cohort study, CVD morbidity and all-cause mortality were inversely related to estVO2max in both men and women of all age-groups. Increasing cardiorespiratory fitness is a clear public health priority.

    Stillasittandets effekter på barns hälsa är underbeforskat: Svårt att definiera säker gräns för ökad risk för ohälsa2015Inngår i: Läkartidningen, ISSN 0023-7205, E-ISSN 1652-7518, Vol. 112, nr 25-26Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [sv]

    Sammanfattat:

    De få studier som gjorts om stillasittande hos barn har fokuserat på övervikt och metabola risker.

    Den svaga kopplingen mellan stillasittande och metabola effekter kan bero på att dessa tillstånd inte har hunnit manifesteras hos barn.

    Fler longitudinella studier med upprepade mätpunkter och objektiv mätmetodik behövs.

    Andra utfall, t ex kognition, bör studeras.

    Physical Education and Leisure-Time Physical Activity in Youth Are Both Important for Adulthood Activity, Physical Performance, and Health.2018Inngår i: Journal of Physical Activity and Health, ISSN 1543-3080, E-ISSN 1543-5474, Vol. 15, nr 9, s. 661-670Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The importance of youth physical activity (PA) for adulthood PA, performance, and health was retrospectively evaluated. Methods: A total of 258,146 participants (49% women), aged 19–70, with a first-time health-profile assessment between 1982 and 2015, provided self-reported data on current perceived health, PA, lifestyle, and physical education class participation, and PA outside school hours before age 20. Data on anthropometrics, blood pressure, and estimated maximal oxygen consumption (VO2max) were obtained. Results: Women participating in physical education class, compared with those who did not, had significantly lower OR (range: 0.81–0.87) for perceiving poor overall health, general obesity, and high diastolic blood pressure after adjustment for potential confounders, and increased OR (range: 1.17–1.23) for exercising regularly and a normal/high VO2max in adulthood. For men, the ORs were significantly lower (range: 0.66–0.86) for poor perceived overall health, general, and abdominal obesity. These associations were seen for participants up to 70 years. Increased PA outside school hours revealed even stronger beneficial associations. In joint analyses, both youth and current PA were important for lower OR of poor health and being obese in adulthood. Conclusions: Physical education class participation and additional PA after school hours were both important for perceived health, PA, VO2max, and metabolic health in adulthood up to 70 years.

    Decline in cardiorespiratory fitness in the Swedish working force between 1995 and 2017.2019Inngår i: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 29, nr 2, s. 232-239Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Long-term trend analyses of cardiorespiratory fitness (VO2 max) in the general population are limited.

    OBJECTIVES: To describe trends in VO2 max from 1995 to 2017 in the Swedish working force and to study developments across categories of sex, age, education, and geographic regions.

    METHODS: 354.277 participants (44% women, 18-74 years) who participated in a nationwide occupational health service screening between 1995 and 2017 were included. Changes in standardized mean values of absolute (L·min-1 ) and relative (ml·min-1 ·kg-1 ) VO2 max, and the proportion with low (<32) relative VO2 max are reported. VO2 max was estimated using a submaximal cycle test.

    RESULTS: Absolute VO2 max decreased by -6.7% (-0.19 L·min-1 ) in the total population. Relative VO2 max decreased by -10.8% (-4.2 ml·min-1 ·kg-1 ) with approximately one-third explained by a simultaneous increase in body mass. Decreases in absolute fitness were more pronounced in men vs. women (8.7% vs. 5.3%), in younger vs. older (6.5% vs 2.3%), in short (11.4%) vs. long (4.5%) education, and in rural vs. urban regions (6.5% vs 3.5%), all p<0.001. The proportions with low VO2 max increased from 27% to 46% (p<0.001).

    CONCLUSION: Between 1995 and 2017, there was a steady and pronounced decline in mean cardiorespiratory fitness in Swedish adults. Male gender, young age, short education and living in a rural area were predictive of greater reductions. The proportion with low cardiorespiratory fitness almost doubled. Given the strong associations between cardiorespiratory fitness and multiple morbidities and mortality, preventing further decreases is a clear public health priority, especially for vulnerable groups.

    Infectious episodes before and after a marathon race.2006Inngår i: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 16, nr 4, s. 287-93Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of this study was to investigate the incidence of self-reported infectious episodes (IE) during 3 weeks before (pre-IE) and 3 weeks after (post-IE) a marathon race and relate these figures to training status, running time, socioeconomic and demographic factors. Two questionnaires, including questions about important factors for IE incidence, were given to a representative cohort of 1694 runners (17% of all finishers) in the Stockholm Marathon 2000. Pre-IE incidence in the cohort was 17% with no difference between women and men. Post-IE incidence in the whole cohort was 19% with no significant (P>0.05) difference between women and men. The post-IE incidence in runners without a pre-IE was 16% (P>0.05 to pre-IE incidence). In the group of runners with pre-IE, 33% experienced an IE after the race also (P<0.05 to Pre-IE incidence). A logistic regression analysis showed that younger age and pre race health status and, for men only, experienced nausea during and after the race were depended factors explaining post-IE incidence. Younger runners were more prone to experience IE both before and after the race. There was no relation between training volume 6 months before the race, finishing time and socioeconomic and demographic factors and pre-IE or post-IE. This study does not support the theory of increased infection rate after exhaustive long-distance running ("The Open Window Theory") in recreational runners, but suggests that the sometimes experienced increased rate of infections among athletes can be caused by strenuous exercise too soon after an infection.

    Secular trends of physical fitness in Swedish adults.2007Inngår i: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 17, nr 3, s. 267-73Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of the present study was to study differences in fitness (maximal aerobic power (VO(2max)), balance control, abdominal strength and endurance) and anthropometric data in Swedish women and men (20-65 years of age) between two national cross-sectional samples, studied in 1990/1991 and 2000/2001, respectively. The absolute and relative VO(2max) (aerobic fitness), estimated from a submaximal test, declined with increasing age in both genders. The submaximal test was validated against running VO(2max). Furthermore, the relative aerobic fitness (mL/min/kg) was lower in the 2000/2001 sample in men but not in women. Overall physical activity level was unchanged in both genders. An unexpected finding was that in both samples there were no major differences in relative VO(2max) between men and women of the same age. Combined overweight and obesity (body mass index> or =25) is becoming more prevalent in men, but not in women with prevalence in 2000/2001 of 61% and 38% for men and women, respectively. Balance control and abdominal strength and endurance decrease with increasing age with no differences between the two samples. Thus, the near future health situation for men may be worse, while for women it may be less or no differences compared with today.

    Abstract [sv]

    Psykisk ohälsa är den vanligaste orsaken till sjukskrivning. Fysisk aktivitet kan förebygga många former av ohälsa, men vilka fysiska aktivitetsmönster som gynnar psykisk hälsa och kognitiva förmågor är fortfarande okänt. Denna typ av forskning är komplex och kräver samarbete med många olika aktörer i samhället.

    Physical fitness and overweight in Swedish youths2005Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The aim of the present thesis was to describe the level of physical fitness and prevalence of overweight and obesity in Swedish youths, and their trends over 14 years. Additionally, the relation between fitness and overweight on the one hand and physical activity on the other was examined. In 2001, a total of 2118 children, aged 10, 13 and 16 years, were invited from 48 randomly selected schools in Sweden. Out of these, 1732 or 81.8 % participated in the testing. For trend analyses, data collected in 1987 from a sample of 516 children were used. When subjects in the 2001 sample were analysed according to proposed cut-off values, 15.7% (95% CI: 14.1% to 17.6%) of all subjects were found to be overweight and 4.3% (95% CI: 3.4% to 5.4%) were obese. The total prevalence accordingly being 20.1% (95% CI: 18.3% to 22.0%). This sample proved to be heterogeneous concerning overweight status. When obesity and overweight were combined the highest prevalence (26.6%, 95% CI: 21.2 to 32.7) was found in 10-year-old girls and the lowest (17.5%, 95% CI: 13.6 to 22.2) in 16-year-old girls. The prevalence in 2001 was nearly 2.5 times higher, compared to the 1987-sample. Girls attending schools in smaller towns or on the countryside had a nearly two-fold prevalence of overweight and obesity, compared to girls living in the major cities. The difference was less pronounced in boys. The prevalence of overweight and obesity was related to level of physical activity in 10 and 13 years old children but not in 16 years old. Results from the performance tests in the 1987 and 2001 samples were compared. Concerning cardio-respiratory performance, girls aged 16 years showed only small differences, whereas boys in the 2001 sample performed worse compared to boys in the 1987-sample (46 ml x kg-1 x min-1 vs. 41 ml x kg-1 x min-1 for 1987 and 2001, respectively, and median difference 9.2 %, 95% CI: -16.7 to -2.2). Concerning neuro-muscular performance, the comparisons of results between the 1987 and 2001 samples showed varying results. Generally, performance on the upper body and trunk muscles strength and endurance tests was lower in 2001 compared to 1987. Neuromuscular performance in the lower body differed less. For both boys and girls, differences in neuro-muscular performance between subjects in different activity strata increased with age. Results showed only small differences in neuro-muscular performance between active and less active strata at age 10, but larger at age 13 and 16 years in both boys and girls. And at age 13 and 16 years, neuro-muscular performance differed widely between active and less active girls. At age 10, only small differences were found in cardio-respiratory performance between active and less active subjects (both girls and boys). At age 13 and 16 years both girls and boys showed large differences in cardio-respiratory performance between activity levels, with better performance in more active children.

    Testing the validity of three submaximal ergometer tests for estimating maximal aerobic capacity in children.2014Inngår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 103, nr 5, s. 559-563Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    AIM:

    Aerobic capacity in children has been linked to health-related outcomes, but the validity of existing assessment methods is largely unknown. This study evaluated the validity of the Åstrand-Rhyming, Woynarowska and Olgun Binyildiz methods.

    METHODS:

    Aerobic capacity was estimated from the heart rate response to submaximal ergometer cycling in 62 children aged 11-12 years. Direct measurement of peak oxygen consumption during a graded maximal treadmill test was used as the criterion method.

    RESULTS:

    We found low mean bias for age-adjusted Åstrand-Rhyming data and Woynarowska data, (-14 and 23 mL/min, respectively), low correlation to criterion values (0.81 and 0.74, respectively) and high standard error of estimate (SEE) (340 and 395 mL/min). The Olgun Binyildiz method gave high correlation (0.87) and low SEE (298 mL/min), but large bias (-660 mL/min). All methods underestimated capacity in well-trained children.

    CONCLUSION:

    The Olgun Binyildiz method is recommended for following an individual over time, due to its low random error. But for comparing individual data with those obtained using direct measurements, the Woynarowska or Åstrand-Rhyming method may be the first choice. However, they all underestimated aerobic capacity in well-trained children.

    Cross-sectional trends in cardiovascular fitness in Swedish 16-year-olds between 1987 and 2007.2011Inngår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 100, nr 4, s. 565-9Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    AIM: We sought to investigate the temporal trends in estimated maximal aerobic capacity in adolescents (mean age 16.1).

    METHODS: Analyses were based on data from three population-based samples, collected in 1987 (n=221), 2001 (n=537) and 2007 (n=265). Subjects underwent sub-maximal ergometer testing. Absolute and relative aerobic capacities were estimated using the Åstrand-Ryhming nomogram.

    RESULTS: Compared to 1987, values for estimated relative and absolute maximal aerobic capacities were lower in 2001 and 2007, and values in 2007 were lower compared to 2001, in both boys and girls, except for absolute capacity between 1987 and 2001 in girls. The differences over time did not differ between genders. Absolute values changed from 3.0 and 2.5 L/min in 1987 to 2.5 and 2.2 L/min in 2007, for boys and girls, respectively. Relative values changed from 46.5 and 45.9 mL/min/kg in 1987 to 35.0 and 36.6 mL/min/kg, in 2007, for boys and girls, respectively.

    CONCLUSION: Based on earlier reports on the relationship between aerobic capacity and metabolic risk, the results from the present study provide argument that future public health will be affected negatively.

    Increased Physical Activity Post-Myocardial Infarction Is Related to Reduced Mortality; Results From the SWEDEHEART Registry2018Inngår i: Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, ISSN 2047-9980, E-ISSN 2047-9980, Vol. 7, nr 24, artikkel-id e010108Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background

    With increasing survival rates among patients with myocardial infarction (MI), more demands are placed on secondary prevention. While physical activity (PA) efforts to obtain a sufficient PA level are part of secondary preventive recommendations, it is still underutilized. Importantly, the effect of changes in PA after MI is largely unknown. Therefore, we sought to investigate the effect on survival from changes in PA level, post‐MI.

    Methods and Results

    Data from Swedish national registries were combined, totaling 22 227 patients with MI. PA level was self‐reported at 6 to 10 weeks post‐MI and 10 to 12 months post‐MI. Patients were classified as constantly inactive, increased activity, reduced activity, and constantly active. Proportional hazard ratios were calculated. During 100 502 person‐years of follow‐up (mean follow‐up time 4.2 years), a total of 1087 deaths were recorded. Controlling for important confounders (including left ventricular function, type of MI, medication, smoking, participation in cardiac rehabilitation program, quality of life, and estimated kidney function), we found lower mortality rates among constantly active (hazard ratio: 0.29, 95% confidence interval: 0.21–0.41), those with increased activity (0.41, 95% confidence interval: 0.31–0.55), and those with reduced activity (hazard ratio: 0.56, 95% confidence interval: 0.45–0.69) during the first year post‐MI, compared with those being constantly inactive. Stratified analyses indicated strong effect of PA level among both sexes, across age, MI type, kidney function, medication, and smoking status.

    Conclusions

    The present article shows that increasing the PA level, compared with staying inactive the first year post‐MI, was related to reduced mortality.

    Trends in body mass in Swedish adolescents between 2001 and 2007.2009Inngår i: Acta paediatrica (Oslo, Norway : 1992), ISSN 1651-2227, Vol. 98, nr 3, s. 519-22Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    AIM: (1) Compare BMI standard deviation scores (BMIsds) in 16-year olds in 2001 and 2007 to assess trends. (2) Describe tracking of BMIsds between ages 10 and 16 years, in a longitudinal 6-year follow-up. (3) Identify possible predictors in 2001 for high BMIsds in 2007 and increase in BMIsds between 2001 and 2007. METHODS: A six-year follow-up study on 296 subjects, aged 10 years at baseline and a panel study among 16-year olds. BMIsds was used as the main outcome. RESULTS. No difference in BMIsds in 16-year-old adolescents was found between 2001 and 2007. Strong tracking (r = 0.80, 95% CI: 0.75-0.84) was found for BMIsds between ages 10 and 16 years. Low aerobic capacity and high BMIsds at age 10 years predicted overweight at age 16 years. High BMIsds in 2001 predicted a decline in BMIsds (OR: 0.58, 95% CI: 0.43-0.76) and high level of self-reported moderate-to-vigorous physical activity predicted an increased BMIsds (OR: 1.38, 95% CI: 1.13-1.67). CONCLUSION: There was no difference in prevalence of overweight plus obesity between the 2001 and 2007 samples. Normal weight and good aerobic fitness in 10-year-old children seems to decrease the risk of elevated relative BMI in 16-year olds.

    Cardiorespiratory Fitness, Sedentary Behaviour and Physical Activity Are Independently Associated with the Metabolic Syndrome, Results from the SCAPIS Pilot Study.2015Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, nr 6, artikkel-id e0131586Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: 

    Previous studies on the relation between lifestyle and the metabolic syndrome lack one or several aspects of the physical activity pattern in the analyses or cardiorespiratory fitness. Likewise, both uni- and triaxial accelerometry have been used, though, the predictive validity of these two modes has not been compared.

    OBJECTIVES: 

    The aims of the present study were firstly to investigate the independent relation between cardiorespiratory fitness and physical activity pattern to the metabolic syndrome (MetS) and secondly to examine the predictive validity of uni- and triaxial accelerometry, respectively.

    METHODS: 

    Data was extracted from the SCAPIS pilot study (n=930, mean age 57.7 yrs). Physical activity pattern was assessed by accelerometry. Cardiorespiratory fitness was estimated using cycle ergometry. MetS was defined per the Adult Treatment Panel III from the National Cholesterol Education Program definition.

    RESULTS: 

    Time spent sedentary (OR: 2.38, 95% CI: 1.54-4.24 for T3 vs T1), in light intensity (OR: 0.50, 95% CI: 0.28-0.90) and in moderate-to-vigorous activity (OR: 0.33, 95% CI: 0.18-0.61), as well as cardiorespiratory fitness (OR: 0.24, 95% CI:0.12-0.48), were all independently related to the prevalence of MetS after adjustment for potential confounders, fitness and/or the other aspects of the physical activity pattern. In addition, we found that triaxial analyses were more discriminant, with ORs farther away from the reference group and additional significant ORs.

    CONCLUSION: 

    The finding that several aspects of the physical activity pattern reveal independent relations to the MetS makes new possible targets for behaviour change of interest, focusing on both exercise and everyday life. When assessing the risk status of a patient, it is advised that triaxial accelerometry is used.

    Concurrent and predictive validity of physical activity measurement items commonly used in clinical settings- data from SCAPIS pilot study.2015Inngår i: BMC Public Health, ISSN 1471-2458, E-ISSN 1471-2458, Vol. 15, artikkel-id 978Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND:

    As the understanding of how different aspects of the physical activity (PA) pattern relate to health and disease, proper assessment is increasingly important. In clinical care, self-reports are the most commonly used assessment technique. However, systematic comparisons between questions regarding concurrent or criterion validity are rare, as are measures of predictive validity. The aim of the study was to examine the concurrent (using accelerometry as reference) and predictive validity (for metabolic syndrome) of five PA questions.

    METHODS:

    A sample of 948 middle-aged Swedish men and women reported their PA patterns via five different questions and wore an accelerometer (Actigraph GT3X) for a minimum of 4 days. Concurrent validity was assessed as correlations and ROC-analyses. Predictive validity was assessed using logistic regression, controlling for potential confounders.

    RESULTS:

    Concurrent validity was low-to-moderate (r <0.35 and ROC AUC <0.7) with large misclassifications regarding time spent sitting/sedentary and in moderate-to vigorous PA. The predictive validity of the questions was good, and one question (PHAS) showed an 80 % decreased odds-ratio of having metabolic syndrome, after taking potential confounders into consideration.

    DISCUSSION:

    In this mixed sample of adults, both concurrent and predictive validity vaired between items and between measures of the physical activity pattern. The PHAS and WALK items are proposed for assessment of adherence to PA recommendations.

    CONCLUSION:

    Assessing PA patterns using self-report measures results in methodological problems when trying to predict individual risk for the metabolic syndrome, as the concurrent validity generally was low. However, several of the investigated questions may be useful for assessing risk at a group level, showing better predictive validity.

    Predictors of adolescent fitness levels among Swedish adolescents, a longitudinal study2012Inngår i: Journal of Science and Medicine in Sport, 2012, Vol. 15, nr Supplement 1, s. S185-Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Introduction: It has been consistently demonstrated that low aerobic fitness is causally linked to increased cardio-metabolic risk. Aerobic fitness has also been causally related to cognitive function. From adolescence and onwards, the inter-individual stability ("tracking") in fitness is fairly high. An individual's fitness level in adolescence is therefore a central determinant for future health. However, childhood predictors of adolescent fitness levels are largely unknown. The present study aimed at identifying personal, school-specific and structural determinants in childhood (age 10 yrs) for adolescent aerobic fitness (at age 16 yrs).

    Methods: Body mass index-based overweight status (normal weight vs overweight/obese, according to Cole et al.) and gross motor skills (based on the Tidén-Nyberg test) were measured at baseline in 209 Swedish children (mean [SD] age 9.8 [0.60] yrs) from randomly selected schools on Sweden. Immigration status (self-report) and average household income in quartiles on community level (register obtained) were used as possible structural confounders. Data on educational status of the PE teacher and lesson structure (gender-separated vs mixed classes) was obtained from the PE teacher. At the reexamination (at age 15.8 [0.33] yrs), aerobic fitness was estimated using the Åstrand-Ryhming nomogram. Low aerobic fitness was defined as below the first quartile (29.7 mL x min-1 x kg-1). Risk for low aerobic fitness was assessed using logistic regression

    Results: Risk for low aerobic fitness at follow-up was lower in children who were normal weight (OR: 0.23.95% CI: 0.10 to 0.49) and in children with trained PE-teachers (OR: 0.40, 95% CI: 0.17 to 0.93), but higher among children with poor gross motor skills (OR:1.84, 95% CI 1.08 to 3.13) at baseline. Gender, immigration history, neighborhood economical status and lesson structure were all non-significant predictors of low adolescent fitness.

    Discussion: The results stress the importance for early overweight prevention and treatment and for professional identification and treatment of children with impaired gross motor skills at young ages. In Sweden, a lagre proportion of PE-teachers in lower grades lack formal PE-teacher education, which according to the present study poses a threat to children's future health. Early screening and treatment of children with limited motor proficiencies seems may help children adapting a physically active lifestyle and avoiding low fitness levels in adolescence and young adulthood.

    Predictors of perceived competence in physical activities (PCPA) among Swedish adolescents, a longitudinal study2012Inngår i: Journal of Science and Medicine in Sport, 2012, Vol. 15, nr Supplement 1, s. S113-Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Introduction: An individual's perceived competence in physical activities (PCPA) has been proven a powerful predictor for future physical activity. However, the perception of one¥s competence may differ over time, especially during childhood and adolescence but also between types of physical activities or tasks. Further, the predictors for PCPA are largely unknown, but overweight status and gross motor skills have been proposed as candidates. We sought to identify predictors for general PCPA in Swedish adolescents, and PCPA in three highly prevalent forms of physical activities in Swedish physical education (PE), namely swimming, aerobics and soccer.

    Methods: Body mass index-based overweight status (normal weight vs overweight/obese, according to Cole et al.) and gross motor skills (based on the TidÈn-Nyberg test) were measured in 352 Swedish children (160 girls and 192 boys) at baseline (age 10). Immigration status (self-report) and average community household income level (quartiles, register obtained) at 10 yrs were used as possible socio-cultural confounders. Data on educational status of the PE teacher responsible for education at age 10 yrs was obtained by self-report from the teachers. Self reported data on general PCPA and PCPA in soccer, swimming and aerobics at 16 yrs was obtained at follow-up and predictors for PCPA was identified using logistic regression.

    Results: Being overweight or obese (OR: 2.27, 95% CI: 1.18–4.38) and attending PE classes with unqualified teachers (OR: 2.41, 95% CI: 1.36–4.27) at age 10 yrs were both risk factors for low general PCPA a age 16 yrs. Concerning the selected activities, being overweight or obese at age 10 yrs predicted low PCPA in swimming (OR: 2.67, 95% CI:1.31–5.46) but not in the other activities at age 16 yrs. Poor gross motor skills at age 10 yrs predicted low PCPA at 16 yrs only in soccer (OR:1.48, 95% CI: 1.02–2.13). Female gender (OR: 0.21, 95% CI: 0.13–0.38), and higher socioeconomic status (OR: 0.71 per quartile, 95% CI: 0.55–0.92)at age 10 yrs were both found to be associated to lower risk for low PCPA in aerobics.

    Discussion: Overweight status and educational status of the PE teacher both affect the risk of having low general PCPA. The effect of gender, overweight status, gross motor skill and socio-economy seem to differ between specific activities, indicating that PCPA may be task specific in adolescents. These results may serve as background when planning physical activity interventions. Further, they stress the need for professional PE teachers to teach in younger classes.

    Validity and comparability of a wrist-worn accelerometer in children.2012Inngår i: Journal of Physical Activity and Health, ISSN 1543-3080, E-ISSN 1543-5474, Vol. 9, nr 3, s. 389-393Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND:

    Wrist-worn accelerometers may provide an alternative to hip-worn monitors for assessing physical activity as they are easier to wear and may thus facilitate long-term recordings. The current study aimed at a) assessing the validity of the Actiwatch (wrist-worn) for estimating energy expenditure, b) determining cut-off values for light, moderate, and vigorous activities, c) studying the comparability between the Actiwatch and the Actigraph (hip-worn), and d) assessing reliability.

    METHODS:

    For validity, indirect calorimetry was used as criterion measure. ROC-analyses were applied to identify cut-off values. Comparability was tested by simultaneously wearing of the 2 accelerometers during free-living condition. Reliability was tested in a mechanical shaker.

    RESULTS:

    All-over correlation between accelerometer output and energy expenditure were found to be 0.80 (P < .001).Based on ROC-analysis, cut-off values for 1.5, 3, and 6 METs were found to be 80, 262, and 406 counts per 15 s, respectively. Energy expenditure estimates differed between the Actiwatch and the Actigraph (P < .05). The intra- and interinstrument coefficient of variation of the Actiwatch ranged between 0.72% and 8.4%.

    CONCLUSION:

    The wrist-worn Actiwatch appears to be valid and reliable for estimating energy expenditure and physical activity intensity in children aged 8 to 10 years.

    Health-related fitness in Swedish adolescents between 1987 and 2001.2004Inngår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 93, nr 5, s. 681-6Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    AIM: To assess trends in neuro-muscular and cardio-respiratory fitness and morphological fitness in Swedish adolescents between 1987 and 2001. METHODS: Comparison of data from two samples, one from 1987 (n = 479) and one from 2001 (n = 1470). Subjects underwent functional tests of muscular strength in the lower limbs, trunk and upper body, sub-maximal ergometrics, and measurement of body mass and height. RESULTS: Cardio-respiratory fitness showed only small changes between 1987 and 2001 among boys, with no changes in girls. Neuro-muscular fitness, as measured by three functional tests, was lower in 2001 compared to 1987. The most pronounced changes in these functional tests were found in the arm-hang test, while changes in lower body and trunk strength tests were less. Our results indicate that the difference in the prevalence of overweight in adolescents between 1987 and 2001 is mainly due to a large change in the most unfit group. The fittest group showed only marginal changes. CONCLUSION: We suggest that the differences in neuro-muscular fitness are at least partly due to differences in the amount and nature of physical activity, and that this might lead to consequences for health later in life.

    Physical performance and body mass index in Swedish children and adolescents2005Inngår i: Scandinavian Journal of Nutrition/Næringsforskning, ISSN 1102-6480, E-ISSN 1651-2359, Vol. 49, nr 4, s. 172-179Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Physical fitness and overweight are both important health-related parameters. Reference data from a population are important for comparisons with children with impairments, different diseases, in habilitation or rehabilitation after injuries. Objective: The aim of the survey was to obtain reference data on physical performance in Swedish children and adolescents aged 10, 13 and 16 years. In addition, height and body mass were assessed and body mass index (BMI) was calculated. Design: In total, 2118 children and adolescents in 48 randomly selected schools in Sweden were invited and 1737 subjects participated. Testing procedures were similar to the Eurofit tests, but with some modifications. Results : Results show generally better performance in boys than in girls and increasing performance with age. BMI increased with age with only small differences between genders. Large variations were found within age and gender groups. Conclusions: The present studyprovides reference data on physical performance and body size in Swedish children and adolescents. The results from the present study may be used to compare performance and anthropometric data over time or between countries, to evaluate performance in different patient groups or to set goals for athletes.

    Prevalence and regional differences in overweight in 2001 and trends in BMI distribution in Swedish children from 1987 to 2001.2004Inngår i: Scandinavian Journal of Public Health, ISSN 1403-4948, E-ISSN 1651-1905, Vol. 32, nr 4, s. 257-63Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    AIMS: This study was undertaken to assess current prevalence and regional differences of overweight in 2001 and changes in body mass index (BMI) distribution between 1987 and 2001 in Swedish adolescents. METHODS: Comparison was made of two independent samples. For assessment of prevalence and regional differences in 2001, a total of 1732 subjects were used. For trend analyses a total of 1,949 children (516 and 1,470 in 1987 and 2001, respectively), aged 10, 13, and 16 years. RESULTS: The prevalence of overweight in 2001 was between 21.7% and 13.3% for boys and girls aged 10 to 16 years and the prevalence of obesity was between 2.9% and 6.2%. Mean BMI as well as prevalence of overweight and obesity was higher in subjects from schools in smaller towns or from the countryside. Median BMI among adolescents changed from 1987 to 2001, most notably in 13- and 16-year-old children. The prevalence of overweight and obesity combined has changed more than 2.5-fold in children aged 10 to 16 years. In this study, the most pronounced elevation in BMI is found in the upper part of the BMI spectrum. This change is especially apparent in girls. CONCLUSION: The change in mean BMI and prevalence of overweight and obesity in children in this study is mainly due to the pronounced change in BMI at the upper end of the spectrum, indicating that the factors leading to overweight or obesity have changed in only a subgroup of the child population.
