This systematic review of systematic reviews addresses a current gap in evidence by synthesizing findings relating to weight management interventions set entirely in primary/elementary schools targeting, diet, and/or physical activity as key strategies. Eight databases were searched for systematic reviews of trials of school‐based interventions targeting children aged 4 to 12 years that looked at biometric and behavioral outcomes. From the 10 selected systematic reviews, we found that interventions designed to promote physical activity or reduce sedentary behavior were most effective for weight loss. Interventions designed to improve diet and nutrition had a small effect on behavioral and cognitive outcomes, and these outcomes could be enhanced through the use of experiential learning. The most effective interventions involved a range of stakeholders in the development process and included parents and families in implementation. This systematic review of systematic reviews offers evidence‐based guidance for the development and implementation of multistrategy weight‐management interventions in primary/elementary schools.

以小学/小学为基础的干预措施是否有效预防/减轻了体重增加？对系统评价的系统评价。

这项系统的系统评价是通过综合与体重控制干预措施相关的研究结果，从而解决当前证据方面的不足，这些干预措施完全设置在针对小学/小学的目标，饮食和/或体育锻炼中，这是关键策略。搜索了八个数据库，以针对针对4至12岁儿童的以学校为基础的干预试验的系统评价，这些试验研究了生物识别和行为结果。从10篇系统评价中，我们发现旨在促进体育锻炼或减少久坐行为的干预措施最有效地减轻了体重。旨在改善饮食和营养的干预措施对行为和认知结果的影响很小，可以通过使用体验式学习来增强这些结果。最有效的干预措施包括发展过程中的一系列利益相关者，并在实施过程中包括父母和家庭。对系统评价的系统评价为小学/小学多策略体重管理干预措施的制定和实施提供了循证指导。
