Long-term self-implemented school interventions for increased physical activity among older youth : A systematic review and meta-analysis (English)
Abstract [sv]

Bakgrund: Fysisk aktivitet korrelerar med både fysiska och psykiska hälsomarkörer. Vid ökad ålder minskar den fysiska aktiviteten och färre når de gällande rekommendationerna. Skolinterventioner kan vara relevanta åtgärder för att öka ungas fysiska aktivitet då mycket av unga individers tid spenderas på skolor. Tidigare forskning indikerar att det är svårt att uppnå varaktiga effekter genom skolinterventioner. Det kan krävas långvariga interventioner för att en ökad fysisk aktivitet ska kunna bibehållas bland skoleleverna. För att interventionerna ska kunna pågå under långa perioder är det nödvändigt att de är egenimplementerade vilket innebär att samhällsaktörerna själva håller i interventionerna. Syfte: Att undersöka effekten på fysisk aktivitet hos långvariga, egenimplementerade skolinterventioner med målet att öka fysisk aktivitet hos äldre unga. Metod: En systematisk översikt och metaanalys genomfördes. SPORTDiscus, PsycINFO, MEDLINE, CINAHL, SCOPUS, ERIC och Web of Science granskades efter RCT-studier som avslutades med minst 6 månaders egenimplementerad intervention. Endast studier som använde objektiva mätmetoder inkluderades. Subgruppsanalyser genomfördes för att hitta samband mellan särskilt framtagna faktorer och förbättrad interventionseffekt. De utfall som undersöktes var daglig måttlig- till högintensiv fysisk aktivitet (eller ”moderate to vigorous physical activity”, MVPA) i minuter, daglig procentuell MVPA och daglig fysisk aktivitet på lätt, måttlig eller hög intensitet. Resultat: Totalt nio studier inkluderades och sju av dem visade positiva effekter. Positiva effekter noterades för alla utfall utom daglig procentuell MVPA. Bland studierna som ingick i metaanalysen fanns det en positiv effekt för daglig MVPA i minuter med 2.04 (95% CI, 0.02, 4.05; P=0.05). Subgruppsanalysen visade att föräldrainvolvering och involvering av båda könen ledde till bäst interventionseffekter. Konklusion: Denna studie visar att långvariga egenimplementerade skolinterventioner har en liten effekt på fysisk aktivitet på samtliga intensitetsnivåer. Evidensen har dock sina begränsningar och mer framtida forskning krävs.

Abstract [en]

Background: Physical activity correlates with both physical and psychological health markers. With increased age the physical activity levels decrease and less people reach the recommendations. School interventions can be relevant solutions to improve physical activity among youth since they spend a lot of time in school. Earlier research indicate that it is hard to obtain maintainable effects from school interventions. What might be needed are long-lasting interventions to maintain the improved physical activity levels among the students. For the interventions to last in the long-term it is necessary for them to be self-implemented, meaning that the social actors implement the interventions. Purpose: To investigate the effects on physical activity in long-term, self-implemented school interventions with the aim to increase physical activity among older youth. Methods: A systematic review and meta-analysis was conducted. SPORTDiscus, PsycINFO, MEDLINE, CINAHL, SCOPUS, ERIC and Web of Science were searched for RCT studies ending with at least 6 months of self-implemented intervention. Only studies using objective measurement methods were included. Sub-group analyses were performed to find correlations between certain composed factors and an improved intervention effect. The measures which were investigated were daily moderate to vigorous physical activity (or MVPA) in minutes, daily percentage of MVPA and daily physical activity on light, moderate or vigorous intensity. Results: A total of nine studies were included and seven of them showed positive effects. Positive effects were found for all measures except daily percentage of MVPA. Among the studies included in the meta-analysis there was a positive effect for daily MVPA in minutes with 2.04 (95% CI, 0.02, 4.05; P=0.05). The sub-group analysis showed that parental involvement and an involvement of both genders led to the best intervention effects. Conclusion: This study shows that long-term self-implemented school interventions have a small effect on physical activity in all intensities. The evidence has its limits though and more future research is needed.
