目的：评估旨在改善教师实施学校体育活动（PA）政策对学生PA水平的多策略干预的影响。方法：采用整群随机对照试验，在12所小学进行。政策的实施要求学校每周通过体育课、运动或以班级为基础的活动（如能量器）为学生提供150分钟有组织的PA。学校获得了利用理论领域框架设计的实施支持，以帮助它们实施现行政策。结果：共有1，502名幼儿园至六年级的儿童参加。在随访中，与对照组相比，通过加速度计测量，参加干预学校的学生每分钟上学天数的增加显著更大（97.5; 95%置信区间[CI]，64.5至130.4; P
Aim: To assess the impact of a multistrategy intervention designed to improve teachers' implementation of a school physical activity (PA) policy on student PA levels. Methods: A cluster-randomized controlled trial was conducted in 12 elementary schools. Policy implementation required schools to deliver 150 minutes of organized PA for students each week via physical education, sport, or class-based activities such as energizers. Schools received implementation support designed using the theoretical domains framework to help them implement the current policy. Results: A total of 1,502 children in kindergarten to grade 6 participated. At follow-up compared with control, students attending intervention schools had, measured via accelerometer, significantly greater increases in school day counts per minute (97.5; 95% confidence interval [CI], 64.5 to 130.4; P
