摘　　要：目的了解高中生在居家网课期间身体活动、焦虑症状状况及其相关性,为高中生的身心健康干预提供科学依据。方法2020年4月,某校高中生以问卷星形式完成在线调查,内容包括:一般资料、生活作息、身体活动、焦虑自评量表。采用成分等时替代模型分析高中生24 h行为活动(包括身体活动、静坐行为和睡眠)与焦虑症状的相关性。结果共调查1324人,高中生焦虑症状患病率为23.34%。10 min中高强度身体活动(MVPA)替代久坐行为(SB)、低强度身体活动(LPA)与焦虑得分减少相关有统计学意义(平均变化量分别为-0.25(95%CI:-0.47~-0.04)、-0.24(95%CI:-0.46~-0.02))。随着MVPA替代LPA、SB和睡眠(SLP)的时间增加,焦虑得分预测值减少量增加。结论高中生居家网课期间焦虑情绪不容忽视,进行中高强度身体活动能有效预防焦虑症状发生。Objective To investigate the correlation between physical activity and anxiety of high school students during the COVID-19 epidemic,and to provide scientific basis for the psychological intervention of high school students.Methods In April 2020,high school students in a school completed an online survey using the Questionnaire Star.General information,daily routine,physical activity,and anxiety self-assessment scale were collected.A component isochronous substitution model was used to analyze the correlation between 24-hour behavioral activities including physical activity,sedentary behavior,and sleep and anxiety symptoms in high school students.Results A total of 1324 individuals were investigated,and the prevalence of anxiety symptoms among high school students was 23.34%.Ten minutes medium-to high-intensity physical activity(MVPA)instead of sedentary behavior(SB)and low-intensity physical activity(LPA)were associated with the reduction in anxiety scores[mean changes of-0.25(95%CI:-0.47 to-0.04),-0.24(95%CI:-0.46 to-0.02)].The decrease in predicted anxiety scores increased as the duration of MVPA substitution for LPA,SB and(sleep)SLP increased.Conclusion High school students’anxiety during home-based online classes should not be neglected,and doing moderateto-vigorous physical activity can effectively prevent anxiety symptoms.
