Title [sv]
Hjärnhälsa i skolan - Fysisk aktivitet för hälsosamma hjärnfunktioner bland skolungdomar
Title [en]
Physical Activity for Healthy Brain Functions in School Youth
Abstract [sv]
Forskningsprojektet ”Fysisk aktivitet för hälsosamma hjärnfunktioner bland skolungdomar”, förkortat ”Hjärnhälsa i skolan”, syftar till att undersöka förhållanden mellan vanemässig fysisk aktivitet och hälsosamma hjärnfunktioner (dvs goda tankemässiga funktioner och god psykisk hälsa), de akuta neurofysiologiska effekterna av fysisk aktivitet, stillasittande och kost, samt hur skolor kan bedriva fysisk aktivitet för främjande av hälsosamma hjärnfunktioner.

Kärnfrågan i projektet lyder: Vilket är förhållandet mellan fysisk aktivitet, stillasittande, kost och hälsosamma hjärnfunktioner bland skolungdomar, och hur kan fysisk aktivitet för främjande av hjärnhälsa på att långsiktigt hållbart sätt genomföras i skolor?

Bakgrunden till forskningsfrågan står att finna i den växande psykiska ohälsan och sänkta skolresultat bland barn och ungdomar i Sverige och de flesta andra länder i västvärlden. Psykisk ohälsa betyder inte bara ökat lidande utan också sämre förmåga att studera och arbeta och en högre risk för framtida sjukdomar. Nedsatta kognitiva förmågor kan påverka möjligheten att klara akademisk utbildning och utgör därför ett hot mot svensk konkurrenskraft i ett globalt perspektiv. Projektet ”Hjärnhälsa i skolan” fångar upp flera av de globala målen för hållbar utveckling i Agenda 2030 och bidrar till att förvandla målen till affärsmöjligheter.

Med finansiering från Kunskaps- och kompetensstiftelsen (KK-stiftelsen) samarbetar forskare från GIH i projektet med företagen Coop, IKEA, Skandia, Skanska samt med de enskilda organisationerna Konsumentföreningen Stockholm (KFS) och Kronprinsessparets stiftelse, Generation PEP, i ett försök att motverka trenden med psykisk ohälsa bland skolungdomar.

Det finns en akut brist på kunskap om förhållandet mellan fysisk aktivitet, stillasittande samt kost och hälsosamma hjärnfunktioner, vilket förhindrar utveckling av verksamheter såväl som varor och tjänster. Vidare finns det kunskapsluckor när det gäller hur skolor kan arrangera regelbunden och meningsfull fysisk aktivitet för skolbarn under skoldagen.

Kärnfrågan undersöktes i tre delprojekt. Forskning inom delprojekt 1 tog fram ny kunskap om de övergripande relationerna mellan fysiska aktivitetsmönster, kost och hälsosamma hjärnfunktioner bland skolungdomar. Denna kunskap fungerade som underlag för studier inom delprojekt 2 av akuta neurofysiologiska och psykologiska effekter av viss fysisk aktivitet samt frukost på fysiologiska mekanismer av betydelse för hälsosamma hjärnfunktioner. I delprojekt 3 genomfördes kvalitativa undersökningar kring hur fysisk aktivitet bland ungdomar sker under en vanlig skoldag och hur skolan jobbar med uppdraget att erbjuda fysisk aktivitet inom ramen av skoldagen.

Två ytterligare projekt togs fram utifrån de första tre delprojekten. Under våren 2021 kontaktades deltagarna i delprojekt 1 igen för att undersöka hur COVID-19 pandemin som bröt ut under början av år 2020 hade påverkat deras fysisk aktivitet, livsstil och hälsa. Resultat från delprojekten användes även som utgångspunkt för insatser i skolor, där skolpersonal i samarbete med forskare, affärspartners och enskilda organisationer, samverkar för att finna vägar till regelbunden och meningsfull fysisk aktivitet under skoldagen i syfte att främja hälsosamma hjärnfunktioner, se mer om det projektet här.

Abstract [en]

Introduction

The family is assumed to be fundamental in youth socialization processes and development, connected to social and cultural practices such as healthy lifestyles and physical activity. However, gender patterns in physical activity among adolescents and the structural drivers of gender inequality (e.g., parentage and siblingship) are poorly understood. The aim of this study was to explore further how gender structures relate to adolescents' time spent being sedentary and physically active, using contemporary gender theory.

Methods

This cross-sectional study involved 1,139 adolescents aged 13-14 and their parents, including 815 mothers and 572 fathers. Physical activity and time spent sedentary were assessed through accelerometry among adolescents and through a self-report questionnaire for parents validated against accelerometry.

Results

The results showed significant relationships between mothers' moderate-to-vigorous physical activity (MVPA) and girls' MVPA on weekdays and weekends, and fathers' MVPA was significantly related to girls' MVPA on weekdays. Our results imply that the relationship between Swedish parents' and adolescent girls' physical activity in higher intensities are to some extent gendered practices. However, time spent sedentary does not seem to show any patterns of being performed according to binary ideas of gender. Further, our exploratory analyses suggest that these results somewhat intersect with parents' educational level and relate to intra-categorical aspects of doing gender. The results also indicate slight gendered patterns in the “doing” of brotherhood for time spent sedentary, however, for boys only on weekends.

Discussion 

The study contributes to the understanding of gender norms as constraints and enablers for adolescents' participation in physical activity. The results can spur public health and physical activity research to apply a contemporary gender theory approach, and to expand the research agenda connected to what relates to gender inequalities in physical activity practices.

Abstract [en]

Purpose: Beneficial acute effects of dietary nitrate have been demonstrated on working memory in adults, with changes in cerebral blood flow (CBF) being a potential mechanism. However, these effects have not been studied in adolescents. Moreover, having breakfast compared to skipping may also exhibit positive effects on working memory. Therefore, this randomized crossover trial investigated the acute effects of nitrate and breakfast on working memory and changes in task-related CBF in adolescents.  Methods: This trial will recruit at least 43 adolescents (13–15 years old). There were three experimental breakfast conditions: (1) none, (2) regular, and (3) regular breakfast with high nitrate in the form of concentrated beetroot juice. Working memory (1-, 2-, 3-back tests) and task-related CBF (prefrontal cortex oxygenated and deoxygenated-hemoglobin changes estimated using functional near-infrared spectroscopy) were measured immediately after breakfast and 130 min later. The data collection for this study is ongoing, thus results for 35 adolescents are presented here and due to blinding of the researcher we are unable to report at this time in which condition these effects occurred, but will be revealed by the time of the conference, as well as for the results on changes in CBF.  Results: Preliminary results from the ongoing study showed that from pretest to posttest there was a statistically significant improvement in reaction time in all three conditions for all three n-back tests, but no intervention effects. Accuracy, however, improved from pretest to posttest in only one condition, for all three nback tests (β [95% confidence interval] from linear mixed-effects models with subject as random effect: 1-back 2.8[1.2-4.3], 2-back 2.6[0.9-4.2], 3-back 3.6[2.2-5.0]), and there was a tendency towards an intervention effect between this breakfast condition and another on the accuracy of the 3-back test (P for time-by-condition interaction 0.07).   Conclusions: The results from this study will increase our understanding into the effects of breakfast and its composition (i.e., nitrate-rich) on acutely improving working memory in adolescents and the potential mechanisms. In turn, the results will inform on whether policies on providing breakfast in schools should be considered to improve students' cognitive performance.

Abstract [en]

BACKGROUND: Inorganic nitrate has been shown to acutely improve working memory in adults, potentially by altering cerebral and peripheral vasculature. However, this remains unknown in adolescents. Furthermore, breakfast is important for overall health and psychological well-being. Therefore, this study will investigate the acute effects of nitrate and breakfast on working memory performance, task-related cerebral blood flow (CBF), arterial stiffness, and psychological outcomes in Swedish adolescents.

METHODS: This randomised crossover trial will recruit at least 43 adolescents (13-15 years old). There will be three experimental breakfast conditions: (1) none, (2) low-nitrate (normal breakfast), and (3) high-nitrate (concentrated beetroot juice with normal breakfast). Working memory (n-back tests), CBF (task-related changes in oxygenated and deoxygenated haemoglobin in the prefrontal cortex), and arterial stiffness (pulse wave velocity and augmentation index) will be measured twice, immediately after breakfast and 130 min later. Measures of psychological factors and salivary nitrate/nitrite will be assessed once before the conditions and at two-time points after the conditions.

DISCUSSION: This study will provide insight into the acute effects of nitrate and breakfast on working memory in adolescents and to what extent any such effects can be explained by changes in CBF. This study will also shed light upon whether oral intake of nitrate may acutely improve arterial stiffness and psychological well-being, in adolescents. Consequently, results will indicate if nitrate intake from beetroot juice or if breakfast itself could acutely improve cognitive, vascular, and psychological health in adolescents, which can affect academic performance and have implications for policies regarding school meals.

TRIAL REGISTRATION: The trial has been prospectively registered on 21/02/2022 at https://doi.org/10.1186/ISRCTN16596056. Trial number: ISRCTN16596056.

Abstract [en]

AIM: Physical activity patterns in adolescents have been associated with general health. Stress, screen-time and sleep are other factors associated with physical activity that influence health in adolescents. Physical activity accounts for several health benefits; however, the impact of organised sports participation to achieve the same health benefits are less explored. This study explored the associations of organised sports participation with general health, stress, screen-time and sleep-duration in adolescents.

METHODS: For this cross-sectional study, data from 1139 adolescents (age 13-14 years) from 34 schools were analysed. Data were collected during autumn 2019. Data collection consisted of self-reported questionnaires and standard methods for height and weight measurements.

RESULTS: Adolescents with organised sports participation ≥3 times/week were twice as likely to report better general health (OR: 2.11, CI: 1.45-3.07) and lower screen-time (OR: 1.98, CI: 1.43-2.74). Adolescents with organised sports participation ≥3 times/week were less likely to meet the recommended sleep-duration on weekdays (OR: 0.43, 95% CI: 0.29-0.65).

CONCLUSIONS: Adolescents with frequent organised sports participation had better general health, lower amounts of screen-time and shorter sleep-duration on weekdays than those with no participation. Although the causal relationships remain unknown, these results can be relevant when developing strategies promoting physical activity and health in adolescents.

Abstract [en]

BACKGROUND: The COVID-19 pandemic has had major impact on the daily lives of adolescents. This study examined whether mental health outcomes had changed over the pandemic, and if such changes were related to changes in physical activity (PA), sedentary time, sleep, screen time, and participation in organized sports.

MATERIALS AND METHODS: In this longitudinal study, data were collected in autumn 2019 with follow-up measurements in spring 2021. In total, 558 schools were invited and 34 schools around Stockholm with a variation in socioeconomic background were included. Physical activity and sedentary time were measured for seven consecutive days by accelerometry (Actigraph). Anxiety, health-related quality of life (HRQoL), psychosomatic health, stress, sleep duration, screen time, and organized sports participation were self-reported in questionnaires. Linear models were applied to estimate associations between changes in mental health outcomes and exposures.

RESULTS: From the baseline sample of 1,139 participants, 585 (55% girls), mean (SD) age 14.9 (0.3) years, participated in the follow-up. Between 2019 and 2021, there was a decrease in HRQoL [mean difference -1.7 (-2.3, -1.2), p < 0.001], increase in psychosomatic health problems [mean difference 1.8 (1.3, 2.3), p < 0.001], and an increase in the number of participants with high stress [from 94 (28%) to 139 (42%), p < 0.001]. Weekly light PA and sleep duration decreased and weekly sedentary time and screen time increased unrelated to changes in mental health outcomes. An increase in sleep duration during weekdays was significantly related to both a decrease in anxiety (B = -0.71, CI: -1.36, -0.06) and an increase in HRQoL (B = 1.00, CI: 0.51, 1.49).

CONCLUSION: During the COVID-19 pandemic, mental health appears to have been impaired in Swedish adolescents, but unrelated to changes in PA, sedentary time, screen time, or participation in organized sports. However, increased sleep duration on weekdays was related to less anxiety and better HRQoL. The results may help policy makers and other stakeholders comprehend the differential effects of the COVID-19 pandemic on mental health outcomes and help guiding the planning of policy actions.

Abstract [en]

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic had a huge impact on daily life, even in countries such as Sweden where the restrictions were relatively mild. This paper assesses the effects of the COVID-19 pandemic restrictions on physical activity (PA) patterns, screen time, and sleep among Swedish adolescents. The exposures explored include gender, parental education, anthropometrics, and cardiovascular fitness (CVF).

METHODS: Cohort data were collected from September 26th to December 6th, 2019, and from April 12th to June 9th, 2021. Participants were 13-14 years-old (7th graders) at baseline with 585 participating at both baseline and follow-up. At both baseline and follow-up PA and sedentary time were measured with accelerometers, and sleep and screen time with questionnaires. The exposure variables (gender, parental education, anthropometrics and CVF) were collected at baseline. Multilevel linear regression analyses were performed.

RESULTS: Moderate-to-vigorous-physical activity (MVPA) remained unchanged while light physical activity (LiPA) decreased and sedentary time increased. Sleep duration decreased and screen time increased. Girls, adolescents with overweight/obesity (BMI and percent body fat), and those with lower CVF at baseline had less favourable changes in PA patterns, sleep and screen time.

CONCLUSIONS: Although no significant (α = 0.05) changes were seen in MVPA, both LiPA and sedentary time as well as sleep and screen time changed in unfavourable ways. More intense activities are often organised and seem to have withstood the pandemic, while less intense activities decreased. Some groups were more vulnerable and will need directed intervention in the post-pandemic period as well as when future pandemics hit.

Abstract [en]

Aim

In adults, prolonged periods of sitting have been linked to acute negative effects on vascular structure and function. The aim of this study was to evaluate the acute effects of physical activity (PA) breaks during prolonged sitting on arterial stiffness, cortisol and psychological factors in adolescents.

Methods

Adolescents underwent different short (3-min) breaks starting every 20 min, during 80 min of sitting on three separate days. Breaks were (A) social seated breaks (SOC), (B) low-intensity simple resistance activity PA breaks (SRA) and (C) moderate-intensity step-up PA breaks (STEP). The arterial stiffness measures were augmentation index (AIx), AIx@75 and pulse wave velocity (PWV). Cortisol was measured from saliva. Psychological factors were self-reported.

Results

Eleven girls and six boys (average age 13.6 ± 0.7 years) participated, with average baseline heart rates of 72 ± 11 bpm, systolic/diastolic blood pressure 111 ± 7/64 ± 6 mmHg and cortisol 10.9 ± 5.8 nmoL/L. PWV, cortisol and psychological factors did not change after any of the conditions. AIx@75 increased significantly (4.9 ± 8.7–9.2 ± 13.2) after the STEP intervention compared with SOC and SRA (time × condition p < 0.05).

Conclusion

Arterial stiffness increased after prolonged sitting with frequent, short step-up activity breaks. The results indicate potential important intensity-dependent effects of physical activity on vascular regulation in youth.

Abstract [en]

Purpose: The COVID-19 pandemic has had an impact on daily life around the world though in Sweden the restrictions have been rather mild. The aim is to explore whether the pandemic has led to changes in physical activity (PA) patterns, including sedentary time, Light Physical Activity (LiPA) and Moderate-to-Vigorous-Physical Activity (MVPA) during weekdays and weekends, as well as screen time and sleep. The potential predictors explored include gender, parental education, anthropometrics, and cardiovascular fitness (CVF).

Methods: Data were collected in the fall of 2019 and the spring of 2021. The participants were 13-14 years-old at baseline and lived in the Stockholm area. In total 585 participated at both baseline and follow-up. PA and sedentary time were measured with accelerometers and sleep and screen time with questionnaires at baseline and follow-up. The exposure variables were collected at baseline: gender and parental education via questionnaire, anthropometrics (BMI and body fat percentage measured with standard methods by researchers) and CVF with a submaximal test. Multilevel linear regression analyses were performed.

Results: MVPA remained unchanged while LiPA decreased by 25.5 minutes on weekdays and 10.3 minutes on weekends (both p<0.001) and sedentary time increased by 9.4 minutes on weekdays (p=0.023). Sleep duration decreased by 27.4 minutes on weekdays and 19.1 minutes on weekends (both p<0.001) and screentime increased by around 45 minutes both on weekdays and weekends (p<0.001). Girls, adolescents with overweight/obesity (BMI and percent body fat), and those with lower CVF at baseline had less favourable changes in PA patterns, sleep and screen time.

Conclusions: Previous self-reported data seems to suggest a decrease in physical activity due to the pandemic; this study only found such changes to be present in the lower intensity levels of physical activity but not in the MVPA. It is possible that more strenuous physical activity is more often part of organized sport which seems to have prevailed in Sweden despite the pandemic while habitual less intense activity decreased. Some groups were found to be more vulnerable and might need more support to maintain their physical activity levels, both now in the post-pandemic periods and during future pandemics.
