Background: The present study investigates the role of different sources of social support in the relationship of BMI and PA in an international sample of children and adolescents. Methods: Data included 170,211 adolescents (51.5% female), aged 10–16 (M = 13.6, SD = 1.64) from 37 European countries/regions and were retrieved from the 2013/14 Health Behaviour in School-aged Children (HBSC) international database. Results: PA levels in adolescents are lower for girls, decrease with age, and are lower for overweight and obese adolescents compared to underweight and normal-weight adolescents. Peer support and teacher support significantly predict PA (ORpeer = 1.11; ORteacher = 0.97) and vigorous PA frequency (ORpeer = 1.13; ORteacher = 0.94). Family support only affected vigorous PA frequency (OR = 1.03). Family support had a moderating effect on PA in overweight (ORfamily*BMI(overweight) = 0.94) and obese (ORfamily*BMI(obese) = 0.90) adolescents. Peer support had a moderating effect on vigorous PA frequency in obese (ORpeer*BMI(obese) = 1.08) adolescents. Teacher support had a moderating effect on PA (ORteacher*BMI(normal) = 1.05; ORteacher*BMI(overweight) = 1.09) and vigorous PA frequency (ORteacher*BMI(normal) = 1.07; ORteacher*BMI(overweight) = 1.08) in normal-weight and overweight adolescents. Conclusion: Social support helps adolescents to be active. Especially for obese adolescents, support by and relations with peers are important to reach a significant amount of PA.

Zusammenfassung Die Förderung eines aktiven und gesunden Lebensstils ist eine wichtige Aufgabe der Schule und des Sportunterrichts. Interventionsprogramme in diesem Setting besitzen zudem einen hohen Stellenwert zur Förderung körperlicher Aktivität von Kindern und Jugendlichen. Um die Wirksamkeit dieser Interventionsprogramme zu erfassen, ist eine umfangreiche Evaluation notwendig. Ziel der vorliegenden Untersuchung ist die qualitative Bewertung der Implementierungsqualität des CReActivity-Interventionsprogrammes, welches, basierend auf der Selbstbestimmungstheorie, die Förderung der körperlichen Aktivität von Schülerinnen durch den Sportunterricht zum Ziel hat. Zu diesem Zweck wurden leitfadenorientierte Interviews mit Lehrerinnen und Schülerinnen der Interventionsklassen des Projekts durchgeführt. Anschließend wurden die Interviews mithilfe der thematischen Analyse deduktiv-induktiv untersucht, um Erkenntnisse zu gewinnen, wie die Teilnehmerinnen die Intervention erleben und deuten. Die Analyse der Interviews der Lehrerinnen ergab insgesamt acht Themen, in denen die Einhaltung der Programmvorgaben, die Häufigkeit der Implementierung, die Qualität der Programmweitergabe, das Sich-Involvieren der Teilnehmer, die Anwendbarkeit der Intervention und die Akzeptanz aufgegriffen werden. Aus den Interviews mit den Schülerinnen konnten Informationen hinsichtlich der Qualität der Programmweitergabe und des Sich-Involvierens der Teilnehmer gewonnen werden. Insgesamt lassen die Ergebnisse eine von den Lehrerinnen wahrgenommene Wirksamkeit der Maßnahme erkennen, die auf eine hohe Implementierungsqualität verweist. Dennoch lassen die Ergebnisse eine schwankende Implementierungsqualität der einzelnen Lehrerinnen erkennen.

The purpose of this study was to evaluate the efficacy of need-supportive teaching in physical education on girls' daily moderate-to-vigorous physical activity using a mixed method evaluation. 507 sixth-grade girls aged 9–14 years of 33 single-sex physical education classes participated in the cluster randomized control trial. During the 16-week intervention period, trained teachers conducted enhanced physical education lessons which were designed based on self-determination theory. In a randomized process, independent researchers using a computer-based algorithm allocated classes to the trial groups (IG n = 19 classes, CG n = 14). These lessons were subject to repeated systematic observations. The students' perceptions of basic psychological need support and satisfaction in physical education were measured using repeated self-report questionnaires. Students' daily moderate-to-vigorous physical activity (MVPA) was assessed by accelerometry. Semi-structured interviews provided a deeper understanding of how purposively sampled focus groups perceived teacher behavior in physical education. After a separate analysis of qualitative and quantitative data, results were merged to investigate the intervention's efficacy and treatment fidelity. Throughout the school year, the girls' MVPA levels decreased in both groups. Girls who reported their complete physical activity data had a lower body mass index than girls who reported no, or only one or two sets of physical activity data. Results of mixed measures converge on the finding that the teachers in the intervention group provided slightly stronger need support than the control teachers, however, intervention components were not delivered consistently. Therefore, a significant intervention effect on daily MVPA could not be quantified. Autonomy satisfaction significantly predicted MVPA. Qualitative insights of teaching behavior in PE underlined the importance of need support and revealed structural barriers, which compromised the implementation quality.
