Analysis on influencing factors of insufficient sleep time among middle school students in Suzhou

目的 分析中学生睡眠时间不足影响因素,以期为改善中学生睡眠时间不足状况提供线索。方法 随机抽取苏州市1 734名中学生,收集性别、学段、住校情况、≥60 min/d中高强度运动的天数(d/w)和白天户外活动时长(h/d)等信息;采用logistic回归模型分析中学生睡眠时间不足的影响因素。结果 1 734名中学生睡眠时间不足率为64.764%。多因素logistic回归分析发现:女生较男生发生睡眠时间不足的风险性高(OR=1.470,95%CI:1.153~1.873);高中生较初中生发生睡眠时间不足的风险性高(OR=17.378,95%CI:12.028~25.107);白天户外活动时长1~<2、2~<3、≥3 h/d的中学生均较活动时长<1 h/d中学生发生睡眠时间不足的风险性低(OR值分别为0.617、0.663、0.652,95%CI分别为0.452~0.841、0.449~0.978、0.442~0.962)。结论 苏州市中学生睡眠时间不足相当普遍,应引起家庭、学校和社会高度重视。

Objective To analyze the influencing factors of insufficient sleep time among middle school students in Suzhou;to provide clues for the prevention and control of insufficient sleep time among middle school students. Methods A total of 1 734 middle school students in Suzhou were randomly selected and whose information such as gender, school section, residence status, days of moderate and high intensity exercise ≥60 min/d(d/w) and time of outdoor activities(h/d) were collected by student′s health status and influencing factors questionnaire.The logistic regression model was used to analyze the influencing factors of insufficient sleep time among middle school students. Results The rate of insufficient sleep time of 1 734 middle school students was 64.764%. Multivariate logistic regression analysis showed that girls had higher risk of insufficient sleep time than boys(OR=1.470,95%CI:1.153-1.873) while high school students had higher risk than middle school students(OR=17.378,95%CI:12.028-25.107). The risks of insufficient sleep time for outdoor activity duration of 1-2 h/d, 2-3 h/d and ≥3 h/d were lower than that of <1 h/d(OR values were 0.617,0.663 and 0.652;95%CI values were 0.452-0.841,0.449-0.978 and 0.442-0.962;respectively).
