Physical activity among senior primary school students on weekends in Beijing

  Objective  To analyze the duration and influencing factors of moderate and vigorous physical activity(MVPA) on weekends for primary school students in grades 4 to 6 in Beijing, and to provide a reference for formulating health education and promotion measures.  Methods  Multi-stage stratified cluster sampling method was used to randomly select 2 515 students from grades 4-6 in 14 primary schools in Beijing, and a self-administered questionnaire was used to record MVPA on weekend, social demographic characteristics, other related health behaviors and knowledge. Multivariate Logistic regression analysis was used to explore the influencing factors of MVPA on weekends.  Results  The prevalence of insufficient MVPA on weekends in Beijing was 63.54%, and the prevalence was higher among girls (69.92%) than boys (57.81%) (χ2=39.65, P<0.01). Multiple Logistic regression analysis revealed that girls (OR=1.74), living in rural areas (OR=1.41), participants attending general schools (OR=1.34), from divorced family (OR=1.46), and short sleep duration (OR=1.50) were more likely to fail to meet the MVPA recommendations(P<0.05).  Conclusion  It is quite common that no sufficient weekend MVPA among senior primary school students, among them, the outer suburbs and schools with relatively weak teaching resources are the key places that need attention, and girls are the key groups that need attention.
