In our society, children are particularly vulnerable to physical inactivity and excessive sedentary time (ST). The aim of this study was to evaluate the effectiveness of a school-based intervention designed to promote physical activity (PA) and reduce ST in 6- to 10-years-old children from a disadvantaged neighborhood.
The first intervention of this randomized trial was carried out in School 1 in 2017/2018 and 2018/2019, School 2 benefited from the same intervention in 2018/2019. Baseline assessments were realized using accelerometers prior to the intervention (T1-T2), after the first intervention (T3) and after the second intervention (T4). School-based actions targeted children, parents, teachers, physical, and organizational environment of school and politics. The chi-square test of independence was used to analyze the evolution of the moderate and vigorous physical activity (MVPA) and ST.
For School 1, an increase in the percentage of very active children (over 40 minutes MVPA/day) and of having a very low ST (less 240 minutes/day) (p = .00) was found. No further evolution was revealed during the intervention (T2-T3) and 1 year after (T3-T4). For School 2, similar effects on PA and ST were found at T3 (p < .05).
Positive effects occurred before the intervention in each school and then remained stable.
在我们的社会中，儿童特别容易受到身体活动不足和过度久坐时间（ST）的影响。本研究旨在评估一项针对弱势社区 6 至 10 岁儿童的基于学校的干预措施，以促进身体活动（PA）和减少 ST 的效果。
这项随机试验的第一次干预是在 2017/2018 年和 2018/2019 年在学校 1 进行的，学校 2 在 2018/2019 年受益于相同的干预措施。在干预之前（T1-T2）、第一次干预之后（T3）和第二次干预之后（T4）使用加速度计进行基线评估。以儿童、家长、教师、学校的身体和组织环境以及政治为目标的学校行动。独立性卡方检验用于分析中等到剧烈体力活动（MVPA）和 ST 的演变。
对于学校 1，发现非常活跃的儿童（每天进行超过 40 分钟的 MVPA）和久坐时间非常低（每天少于 240 分钟）的百分比增加（p = 0.00）。在干预期间（T2-T3）和干预后 1 年（T3-T4）没有进一步的演变。对于学校 2，在 T3 时也发现了类似的 PA 和 ST 影响（p < 0.05）。
在每所学校，干预前都出现了积极的影响，然后保持稳定。
