BACKGROUND
This systematic review determines the levels of physical activity (PA) during school hours in children and adolescents.
METHODS
Studies carried out from January 1987 to December 2019 were retrieved from four databases (Web of Science, Pubmed, Scopus and SportDiscus). The 29 selected studies were cross-sectional, long-term and case studies.
RESULTS
Most of them used accelerometers and showed that male and female children accumulated a mean of between 14 and 68 min of moderate-to-vigorous PA (MVPA) during school hours (3%-22% of this daily segment), and male and female adolescents accumulated a mean of between 13 and 28 min of MVPA during this daily segment (3%-8% of the school hours). Less than a quarter of children and adolescents reached the recommended 30 min of MVPA during school hours, with notable differences between sexes.
CONCLUSIONS
These results suggest that the levels of PA during school hours are not enough, and consequently, schools should develop strategies for helping children and adolescents reach the school PA recommendation.
背景
本系统评价旨在确定儿童和青少年在校期间的身体活动（PA）水平。
方法
从 1987 年 1 月至 2019 年 12 月，我们从四个数据库（Web of Science、Pubmed、Scopus 和 SportDiscus）中检索了研究。29 项选定的研究为横断面研究、长期研究和病例研究。
结果
它们中的大多数使用加速度计，结果表明，在校期间，男女儿童平均积累了 14 至 68 分钟的中等到剧烈的 PA（MVPA）（这一日段的 3%-22%），而男女青少年在这一日段平均积累了 13 至 28 分钟的 MVPA（这一日段的 3%-8%）。在校期间，不到四分之一的儿童和青少年达到了推荐的 30 分钟 MVPA，男女之间存在显著差异。
结论
这些结果表明，在校期间的 PA 水平不足，因此，学校应制定策略，帮助儿童和青少年达到学校 PA 推荐量。
