(1) The majority of Canadian youth are not meeting physical activity guidelines, and more female than male youth are falling short of these recommendations. School programs and policies are a viable strategy to improve youth physical activity. However, they may differentially affect female and male activity. This study aimed to examine school-level differences in physical activity outcomes among male and female students and to explore how school programs and policies associate with school-level physical activity outcomes among females. (2) This study used data from 136 schools participating in year 7 (Y7 2018-2019) of the COMPASS study. Data on school programs and policies and on student physical activity were collected. School-level means and percentages for outcomes were calculated and compared between males and females and the impact of physical activity programs and policies on female physical activity outcomes were examined. (3) More males met the guidelines, achieved more strength training days and physical activity minutes compared to females. The number of female varsity sports, community partnerships and fitness ambassadors were all positively and significantly associated with female physical activity. (4) Supportive physical activity environments fostered by offering varsity sports, establishing community partnerships and positive role models may promote physical activity among female youth.
(1) 大多数加拿大青少年不符合身体活动指南，而且女性青少年比男性青少年更不符合这些建议。学校计划和政策是提高青少年身体活动的可行策略。然而，它们可能会对女性和男性的活动产生不同的影响。本研究旨在检查男女生在学校层面上的身体活动结果的差异，并探讨学校计划和政策如何与女性的学校层面的身体活动结果相关联。 (2) 本研究使用了参与 COMPASS 研究第 7 年（2018-2019 年 Y7）的 136 所学校的数据。收集了关于学校计划和政策以及学生身体活动的数据。计算了学校层面的结果平均值和百分比，并在男性和女性之间进行了比较，还检查了身体活动计划和政策对女性身体活动结果的影响。 (3) 与女性相比，更多的男性符合指南，实现了更多的力量训练天数和身体活动分钟数。女子大学运动、社区伙伴关系和健身大使的数量均与女性身体活动呈正相关且显著相关。 (4) 通过提供大学运动、建立社区伙伴关系和积极的榜样来营造支持身体活动的环境，可能会促进女性青少年的身体活动。
