摘要:
目的 了解土家族聚居区儿童青少年体力活动状况,为少数民族地区儿童青少年体力活动干预模式提供参考。 方法 对湖北省恩施土家族苗族自治州利川市2所小学的2 466名土家族小学生进行整群抽样,调查小学生体力活动状况,采用χ2检验进行组间比较。 结果 土家族儿童青少年一周内中高等强度活动时长中位数为49.9 min/d,总体达标率为47.93%,其中走读生达标率高于住校生(χ2=80.47,P < 0.01);一周内久坐时长中位数为396.1 min/d,视屏时长合格率为78.99%,且走读生与住校生合格率差异有统计学意义(χ2=35.12,P < 0.01)。 结论 土家族聚居区儿童青少年缺乏体力活动,需采取有效的干预措施,重视儿童青少年体力活动。 Abstract:Objective To understand physical activity status of children and adolescents in Tujia inhabited areas, and to provide reference for the intervention model of physical activity of children and adolescents in minority areas. Methods A cluster sample of 2 466 Tujia pupils from two primary schools in Lichuan City, Enshi Tujia and Miao Autonomous Prefecture of Hubei Province was selected to investigate physical activity status of Tujia pupils. The univariate χ2 test was used to analyze the physical activity status of Tujia children and adolescents and its influencing factors. Results The median duration of high intensity activity was 49.9 minutes/day in the last week, and 47.93% of participants met the physical activity standard(χ2=80.47, P < 0.01), the median duration of sitting was 396.1 minutes/day in the last week, and the qualified rate of screen time was 78.99%, and the differences of qualified rate between day-students and residential students were of statistical differences(χ2=35.12, P < 0.01)). Conclusion The children and adolescents in the Tujia community are lack of physical activity. Therefore, it is necessary to take effective intervention measures to pay attention to the children and adolescents physical activity. -
