【摘要】 目的探讨中小学生睡眠时间与超重肥胖的关系,为制定干预措施提供依据。方法利用多阶段整群抽样方法,于2018年12月至2019年1月,对重庆沙坪坝8所中小学,共5306名在校学生,进行睡眠时间与超重肥胖的调查分析。结果该区中小学生平均睡眠时间为9.21h,不同性别、学段和区域的学生,睡眠时间差异均有统计学意义;学生睡眠时间在<8h,8～8.9h,9～9.9h和≥10h的构成,分别为13.47%,25.63%,29.95%和30.95%,差异有统计学意义。工作日平均入睡时间为21:00,周末节假日为22:00;工作日平均睡眠时间为8.87h小时,周末为10.05h,差异均有统计学意义。中小学生超重与肥胖检出率分别为15.49%和9.18%,超重肥胖检出率随睡眠时间的缩短而升高,差异有统计学意义。调整了性别、学段和区域等因素后,以睡眠时间≥10h作参照,发现周末节假日睡眠不足是肥胖的危险因素,睡眠时间<8h的OR值为1.81(1.09～2.86),<9h的OR值为1.58(1.12～2.19)。结论周末节假日睡眠不足是肥胖的危险因素,应重点改善学生周末节假日的睡眠状况,保证充足的睡眠时间。更多还原

【Abstract】 Objective To explore the relationship between sleep duration and overweight and obesity in primary andmiddle school students, and to provide basis for intervention measures. Methods A multistage cluster sampling method was used to investigate the sleep duration, overweight and obesity among 5306 students from8 primary and secondary schools in the district from December 2018 to January2019.Results The average sleep duration in primary and middle school students in this area was 9.21h, and there were significant differences among different sexes,sections and regions. Sleep duration in < 8 h, 8～8.9 h, 9～9.9 h and(> 10 h) was13.47%, 25.63%, 29.95% and 30.95% respectively, with significant difference in distribution. The median sleeping time of working day was 21:00, weekend holidays was 22:00, and the average sleeping time of working day was 8.87±1.24 hours, weekend was 10.05 ±1.35 hours, the difference was statistically significant.The detection rates of overweight and obesity in students were 15.49% and 9.18% respectively. The detection rates of overweight and obesity in students increased with the shortening of sleep time, and the difference was statistically significant. After adjusting for the factors such as sex, school segment and area,compared with sleeping for more than 10 hours,the OR value of sleep time less than 8 hours was 1.81(1.09～2.86),and the OR value of less than 9 hours was 1.58(1.12～2.19).Conclusion Insufficient sleep on weekends and holidays is a risk factor for obesity. We should focus on improving students’ sleeping conditions on weekends and holidays to ensure adequate sleep time.更多还原
