The effects of school-based physical activity (PA) programs on different cardiometabolic risk factors and the most appropriate features of PA programs to achieve maximum effectiveness are unclear.
To provide a comprehensive synthesis of the effectiveness of school-based PA interventions on cardiometabolic risk factors in children.
We identified studies from database inception to February 22, 2018.
We selected studies that were focused on examining the effect of school-based PA interventions on cardiometabolic risk factors in children.
Random-effects models were used to calculate the pooled effect size (ES) for the included cardiometabolic risk factors (waist circumference [WC], triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, systolic blood pressure and diastolic blood pressure (DBP), and fasting insulin and glucose).
Nineteen randomized controlled trials (which included 11 988 children aged 3-12 years) were included in the meta-analysis. School-based PA programs were associated with a significant small improvement in WC (ES = -0.14; 95% confidence interval [CI]: -0.22 to -0.07; < .001), DBP (ES = -0.21; 95% CI: -0.42 to -0.01; = .040), and fasting insulin (ES = -0.12; 95% CI: -0.20 to -0.04; = .003).
Authors of few studies described the implementation conditions of their interventions in detail, and compliance rates were lacking in most studies. In addition, results by sex were provided in a small number of studies.

以学校为基础的身体活动（PA）计划对不同的心血管代谢风险因素的影响，以及实现最大效果的最适宜 PA 计划特征尚不清楚。
全面综合以学校为基础的 PA 干预对儿童心血管代谢风险因素的有效性。
我们从数据库建立之初到 2018 年 2 月 22 日确定了研究。
我们选择了专注于检查以学校为基础的 PA 干预对儿童心血管代谢风险因素影响的研究。
使用随机效应模型计算纳入的心血管代谢风险因素（腰围 [WC]、甘油三酯、总胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、收缩压和舒张压 [DBP]、空腹胰岛素和葡萄糖）的汇总效应大小（ES）。
19 项随机对照试验（包括 11988 名 3-12 岁儿童）被纳入荟萃分析。以学校为基础的 PA 计划与 WC（ES = -0.14；95%置信区间 [CI]：-0.22 至 -0.07；<0.001）、DBP（ES = -0.21；95% CI：-0.42 至 -0.01；=0.040）和空腹胰岛素（ES = -0.12；95% CI：-0.20 至 -0.04；=0.003）的显著小改善相关。
少数研究的作者详细描述了其干预措施的实施条件，大多数研究缺乏依从率。此外，少数研究提供了按性别划分的结果。
