Most youth in the United States do not meet the recommended 60 minutes of daily physical activity (PA). The school environment offers an opportunity to engage students in PA. The purpose of this study was to evaluate the impact of a comprehensive school-based physical activity program on student PA across student-level and school-level characteristics.
PA levels from 3294 fourth grade students in 24 intervention schools and 7 control schools in metropolitan Atlanta, Georgia were measured during the 2015-2016 academic year. PA measures included daily steps in school, steps taken in physical education class (PE), and percent of PE class time spent in moderate-to-vigorous physical activity (MVPA). Intervention effectiveness was assessed using generalized estimating equations adjusting for sex and school-level socioeconomic status (SES).
After adjusting for sex and school-level SES, intervention students had significantly higher increases in average daily steps (p < .05), steps taken in PE (p < .01), and percent of PE class spent in MVPA (p < .01) than control students.
Our findings demonstrate the effectiveness of CSPAPs in increasing PA. Further research using randomized controlled trials of large-scale implementations, longer follow-up periods, and more diverse student sample is warranted.
美国大多数青少年未达到每日建议的60分钟体育活动量。学校环境为促使学生参与体育活动提供了契机。本研究旨在评估一项全面的校本体育活动计划对不同学生水平和学校水平特征的学生体育活动的影响。
在2015 - 2016学年期间，对佐治亚州亚特兰大市24所干预学校和7所对照学校的3294名四年级学生的体育活动水平进行了测量。体育活动测量指标包括在校每日步数、体育课步数以及体育课中用于中等到剧烈体育活动（MVPA）的时间百分比。使用广义估计方程对性别和学校层面的社会经济地位（SES）进行调整后，评估干预效果。
在对性别和学校层面SES进行调整后，干预组学生在平均每日步数（p < 0.05）、体育课步数（p < 0.01）以及体育课中用于MVPA的时间百分比（p < 0.01）方面的增加幅度均显著高于对照组学生。
我们的研究结果证明了全面校本体育活动计划在增加体育活动方面的有效性。有必要进一步开展大规模实施的随机对照试验、延长随访期并采用更多样化的学生样本进行研究。
