摘　　要：目的系统评价应用加速度计测量的中国学龄前儿童体力活动和久坐行为。方法检索PubMed、Web of Science、中国知网、万方数据库,搜集测量学龄前儿童体力活动和久坐行为的相关横断面研究,检索时限为1998年至2022年4月。由2名评审者独立进行文献筛选、资料提取及质量评价工作后,采用Stata 16.0软件进行Meta分析。结果共纳入23项研究,涵盖中国16个市区4449名学龄前儿童。Meta分析结果显示:中国学龄前儿童日总体力活动时间占比24.4%(190.3min/d,95%CI:158.9~221.6),日中高强度体力活动时间占比8.2%(63.6min/d,95%CI:53.6~73.6),日久坐时间占比67.2%(523.9min/d,95%CI:478.6~569.2)。亚组分析结果表明,女童总体力活动及中高强度体力活动时间均低于男童,而久坐时间高于男童;随年龄增长,儿童中高强度体力活动及久坐时间明显增加,总体力活动时间无变化。结论中国学龄前儿童体力活动水平总体满足现有指南标准,但久坐行为仍然严重。女童体力活动水平尚未达到指南推荐量。ObjectiveTo systematically review the physicalactivity and sedentary behavior in Chinese preschool children using accelerometry.Methods PubMed,Web of Science,CNKI,and Wanfang databases were searched for terms related to preschoolers’physical activity and sedentary behavior from 1998 to April,2022.Twore searcher sindependently screened the literature,extracted the data and assessed the quality of eligible studies.Then meta-analysis was performed by Stata16.0 software.Results Twenty-three studies covering 4449 preschoolers of sixteen urban areas in China were included.The results of meta-analysis showed that the Chinese preschoolers’total physical activity was accounting for 24.4%(190.3 min/d,95%CI:158.9~221.6),moderate-to-vigorous physical activity was accounting for 8.2%(63.6 min/d,95%CI:53.6~73.6),and sedentary behavior was accounting for 67.2%(523.9min/d,95%CI:478.6~569.2).Subgroup analysis showed that girls spent less time on total physical activity and moderate-to-vigorous physical activity than boys,while they were more sedentary than boys.With increasing age,the moderate-to-vigorous physical activity and sedentary behavior increased significantly,but the total physical activity did not change.Conclusion The physical activity of Chinese preschoolers generally meets the existing guidelines,however,they still engage in substantial sedentary behavior.Girls’physical activity levels have not yet reached the guidelines recommendations.
