Physical activity among senior primary school students on weekends in Beijing

Abstract

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%) (χ ²= 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.

【摘要】 目的分析北京市四至六年级小学生周末中髙强度运动(moderate and vigorous physical activity, MVPA)时间及 影响因素, 为制定健康教育与促进相关措施提供参考。 方法采用多阶段分层整群抽样方法在北京市随机抽取14所小学 四至六年级共2 515名学生, 采用自编问卷对其周末MVPA时间、社会人口学特征、其他健康相关行为和健康知识等进行 调査。利用多因素Logistic回归分析探索周末运动时间的影响因素。 结果北京市四至六年级小学生周末MVPA不足率 为63.54%, 女生运动不足率(69.92%)髙于男生(57.81%)(χ ² = 39.65, P<0.01);多因素Logistic回归分析显示, 女生( OR = 1.74)、远郊区学校( OR =1.41)、普通校( OR =1.34)、单亲家庭( OR =1.46)和累计睡眠时间不足( OR =1.50)与周末MVPA 时间不足正性相关( P值均<0.05)。 结论北京市四至六年级小学生周末MVPA时间不足较普遍, 其中远郊区和教学资 源相对薄弱校是需要关注的重点地区, 女生是需要关注的重点人群。
