Sex and educational level differences in physical activity and motivations to exercise among Spanish children and adolescents. Eur J Pediatr. 2023 Feb;182(2):533-542. doi: 10.1007/s00431-022-04742-y.0340-61991432-1076https://hdl.handle.net/10115/37091Children and adolescents worldwide, especially girls, do not meet moderate to vigorous physical activity (MVPA) guide lines, a situation which is related to obesity and other comorbidities. Sex/gender diferences in the practice of MVPA and motivations to engage in physical activity have not been previously examined among Spanish students considering diferent educational levels. Therefore, the purpose of this study was to explore these diferences and analyse if motivations mediate the relationship between educational levels and MVPA in a large sample of students. From diferent schools in the Madrid region (primary: 11,122; lower secondary: 12,379; upper secondary: 3228) 26,729 students (13,491 boys and 13,238 girls; 9–19 years old) were recruited to participate in this study. The short form of the International Physical Activity Questionnaire and the third version of the Behavioural Regulation in Exercise Questionnaire were used to evaluate, MVPA and motiva tions to exercise, respectively. Two-way ANCOVA and a mediation analysis were performed. Female students were found to be less active than males (43.4±38.7 and 58.6±45.9 min of MVPA; p<0.001; ηp2=0.023) and showed lower intrinsic (ηp2=0.003), and integrated (ηp2=0.007) motivations than their male counterparts (p<0.001). Primary school students were more active than lower and upper secondary students (53.3±44.2, 49.9±42.3 and 48.0±42.8 min of MVPA; p<0.001; ηp2=0.002) and also presented higher intrinsic (ηp2=0.011) and integrated (ηp2=0.010) motivation than secondary school students (p<0.001). Conclusion: Among Spanish children and adolescents, females showed lower levels of MVPA and intrinsic and integrated motivation across all the educational levels, and among primary school students in comparison to secondary school. This suggests that inner motivation is more determinant of increased engagement in MVPA and thus, there is need to reinforce it before the transition to secondary school and with special focus on females’ preferences.engsportenablershigh-schooladolescencekidsinfo:eu-repo/semantics/article10.1007/s00431-022-04742-yinfo:eu-repo/semantics/closedAccess
