Intramurals in schools may encourage physical activity among youth. Schools are continuously making changes to these intramurals, yet it is not well understood how these changes impact youth physical activity. The main objective of this research was to examine if changes in the number of intramurals were associated with youth physical activity over time with a secondary objective to explore the association between sport participation and physical activity among youth over time.
This study used three years of linked longitudinal school- and student-level data from Ontario schools in year 5 (Y5: 2016-2017), year 6 (Y6: 2017-2018) and year 7 (Y7: 2018-2019) of the COMPASS study. Data on intramurals from 55 schools were collected from the School Programs and Policies questionnaire to determine intramural changes that were made from Y5 to Y6. Using the COMPASS Student Questionnaire, baseline demographics were collected and data on physical activity and sport participation were measured at Y5, Y6 and Y7 on 4417 students. Hierarchical linear mixed regression models were used to estimate how changes in intramurals were associated with youth physical activity over time.
Changes in school-specific intramurals were not significantly associated with physical activity over time. Intramural, varsity and community sport participation were all positively and significantly associated with youth physical activity among female and males.
Intramural, varsity and community sport participation are important opportunities for youth physical activity. Schools should offer a variety of intramural and varsity sports to encourage physical activity. Although adding intramurals may not be effective at increasing youth physical activity, they may be effective when used in combination with other strategies to increase physical activity.
学校校内体育活动可能会促进青少年的身体活动。学校不断对这些校内体育活动做出改变，但这些变化如何影响青少年的身体活动，目前还没有得到很好的理解。本研究的主要目的是检验随着时间推移校内体育活动数量的变化是否与青少年身体活动相关，次要目的是探讨随着时间推移青少年体育参与和身体活动之间的关联。
本研究使用了来自安大略省学校的三年纵向关联数据，这些数据来自COMPASS研究的五年级（Y5：2016 - 2017年）、六年级（Y6：2017 - 2018年）和七年级（Y7：2018 - 2019年）。从55所学校的学校项目和政策问卷中收集校内体育活动数据，以确定从Y5到Y6所做的校内体育活动变化。使用COMPASS学生问卷收集基线人口统计学数据，并在Y5、Y6和Y7对4417名学生测量身体活动和体育参与数据。使用分层线性混合回归模型来估计随着时间推移校内体育活动的变化与青少年身体活动之间的关联。
特定学校校内体育活动的变化与随着时间推移的身体活动没有显著关联。校内、校队和社区体育参与在男性和女性中均与青少年身体活动呈正相关且显著相关。
校内、校队和社区体育参与是青少年身体活动的重要机会。学校应提供各种校内和校队体育项目以鼓励身体活动。虽然增加校内体育活动可能在增加青少年身体活动方面无效，但当与其他增加身体活动的策略结合使用时可能有效。
