摘要:
目的 探讨在新冠肺炎疫情居家上网课期间某市一至六年级学生睡眠与运动情况的关系,为政府及相关部门制定学生健康促进有关政策提供参考依据。 方法 于2020年4月22日至5月14日,采用分层整群随机抽样法选取某市24 452名小学生进行网络问卷调查,调查内容包括一般情况、睡眠时间、运动情况等。 结果 小学生每天低强度运动参与率为21.6%,中强度运动参与率为9.4%,高强度运动参与率为5.8%;每次参与各类强度运动的时间>30 min的学生比例不足10%;一至六年级小学生睡眠不足报告率分别为22.5%,25.5%,28.9%,31.3%,35.0%,39.9%(χ2=350.75,P < 0.05);多因素Logistic回归分析显示,在调整性别、年级、是否独生等因素以后,进行高强度运动与睡眠不足呈负相关(OR=0.91,95%CI=0.86~0.97)。 结论 各年级小学生睡眠不足较为普遍,小学生进行适量的高强度运动是保证充足睡眠时间的有利因素。 Abstract:Objective To explore the relationship between sleep and exercise among grade 1-6 students in a certain city during the period of home-based online courses in the epidemic, and to provide reference basis for the government and relevant departments to make relevant policies on student health promotion. Methods From April 22 to May 14 in 2020, 24 452 primary school students were selected by stratified cluster random sampling method to network questionnaire survey, which included general situation, sleep time, and exercise. Results Totally 21.6% of primary school students participated in low-intensity exercise, 9.4% in moderate-intensity exercise and 5.8% in high-intensity exercise every day. Less than 10% of the students participated in all types of intense sports for more than 30 minutes each time. The report rate of sleep deprivation among students in grades 1 to 6 was 22.5%, 25.5%, 28.9%, 31.3%, 35.0%, 39.9%, respectively(χ2=350.75, P < 0.05). Multivariate Logistic regression analysis showed that after adjusting for gender, grade, oneness and other factors, high-intensity exercise was negatively correlated with sleep deprivation(OR=0.91, 95%CI=0.86-0.97). Conclusion Insufficient sleep is common among primary students, and appropriate amount of high intensity exercise is a favorable factor to ensure adequate sleep time in primary school students. -
