This systematic evaluation and meta-analysis [PROSPERO CRD42024598218] was conducted in order to summarise the effectiveness of a body of school-based behavioural interventions on physical activity (PA) and sedentary behaviour in children and adolescents.
We conducted a systematic search of the literature up to November 2024 using PubMed, Web of Science and SCOPUS. The methodological quality of the included literature was assessed using the Cochrane Risk Assessment Tool.
Of the 6,071 search records initially identified, 26 studies were considered eligible for systematic evaluation and meta-analysis. School-based behavioural interventions were effective in increasing moderate-intensity physical activity [standardised mean difference (SMD), 0.18 (95% CI, 0.04-0.31), = 0.01]. School-based behavioural interventions failed to reduce ST (sedentary time) [-0.04 (95% CI, -0.08 to -0.01), = 0.12] and failed to improve low-intensity PA (LPA) [0.18 (95% CI, -0.07-0.44), = 0.16]. Subgroup analyses showed that school-based behavioural interventions were more effective in improving moderate-intensity PA in children and adolescents who were in school [0.46 (95% CI, 0.20-0.72), = 0.02]. School-based behavioral interventions do not differentiate moderate-intensity physical activity among children and adolescents of different ages, [0.18 (95% CI, 0.05-0.31), = 0.1], nor do they make a difference in moderate-intensity physical activity among children and adolescents in different regions [0.18 (95% CI, 0.04-0.31), = 0.12].
School-based behavioural interventions are effective in increasing moderate-intensity PA among children and adolescents, particularly those who were in school.

本系统评价和荟萃分析[PROSPERO CRD42024598218]旨在总结一系列基于学校的行为干预措施对儿童和青少年身体活动（PA）及久坐行为的有效性。
我们截至2024年11月使用PubMed、科学网和Scopus对文献进行了系统检索。使用Cochrane风险评估工具评估纳入文献的方法学质量。
在最初识别的6071条检索记录中，26项研究被认为符合系统评价和荟萃分析的条件。基于学校的行为干预措施在增加中等强度身体活动方面有效[标准化均数差（SMD），0.18（95%置信区间，0.04 - 0.31），P = 0.01]。基于学校的行为干预措施未能减少久坐时间[-0.04（95%置信区间，-0.08至-0.01），P = 0.12]，也未能改善低强度身体活动[0.18（95%置信区间，-0.07 - 0.44），P = 0.16]。亚组分析表明，基于学校的行为干预措施在改善在校儿童和青少年的中等强度身体活动方面更有效[0.46（95%置信区间，0.20 - 0.72），P = 0.02]。基于学校的行为干预措施在不同年龄的儿童和青少年中对中等强度身体活动没有差异[0.18（95%置信区间，0.05 - 0.31），P = 0.1]，在不同地区的儿童和青少年中对中等强度身体活动也没有差异[0.18（95%置信区间，0.04 - 0.31），P = 0.12]。
基于学校的行为干预措施在增加儿童和青少年，特别是在校儿童和青少年的中等强度身体活动方面有效。
