To describe the situation of insufficient sleep and the association between insufficient sleep and physical exercise, among Chinese Han students aged 9-18 years. We selected 172 197 Chinese Han students aged 9-18 years from the project 2014 Chinese National Survey on Students Constitution and Health. The average sleep duration per day of less than 9 h for children aged 9-12 years and of less than 8 h for adolescents aged 13-18 years, were defined as insufficient sleep. We described the distribution of sleep duration and the prevalence rates of insufficient sleep for each subgroup. Logistic regression models were established to assess the association between insufficient sleep and physical exercise. In 2014, 6.6%, 30.8%, 26.3%, 20.8%, 13.8% and 1.8% of the Chinese Han students self-reported sleep duration were <6, 6-, 7-, 8- and ≥10 h, respectively. The overall prevalence rate of insufficient sleep was 77.2%, with 75.8% for boys and 78.6% for girls. No gender disparity was found at each 9-11 age groups. However, in the 12-18 age groups, the prevalence rates for girls were significantly higher than that for boys. The prevalence rates of insufficient sleep for primary school, middle school and high school students were66.6%, 74.1% and 93.8%, respectively. Rates were increasing with age for children aged 9-12 years and adolescents aged 13-18 years respectively. The three provinces with the lowest prevalence rates of insufficient sleep were Zhejiang (68.8%), Jiangsu (66.7%) and Shaanxi (65.2%). Data from the logistic regression models revealed that, when comparing to those students with only exercise of <0.5 h per day, the exercise hours of 0.5-1 h (=0.72, 95: 0.69-0.74) or ≥1 h (=0.46, 95: 0.44-0.47) per day seemed as protective factors for insufficient sleep. When compared with physical exercise frequency <2 times per week, the 2 times (=0.82, 95: 0.78-0.86) or >2 times (=0.65, 95: 0.62-0.68) frequencies also appeared as protective. The prevalence rate of insufficient sleep prevailing among students aged 9-18 years was high, in China. Our data called for setting up effective measures to deal with this situation.
描述9至18岁中国汉族学生睡眠不足的状况以及睡眠不足与体育锻炼之间的关联。我们从“2014年中国学生体质与健康调研”项目中选取了172197名9至18岁的中国汉族学生。将9至12岁儿童每日平均睡眠时间少于9小时、13至18岁青少年每日平均睡眠时间少于8小时定义为睡眠不足。我们描述了各亚组的睡眠时间分布及睡眠不足患病率。建立逻辑回归模型以评估睡眠不足与体育锻炼之间的关联。2014年，分别有6.6%、30.8%、26.3%、20.8%、13.8%和1.8%的中国汉族学生自我报告睡眠时间<6、6 - 、7 - 、8 - 和≥10小时。睡眠不足的总体患病率为77.2%，其中男生为75.8%，女生为78.6%。在9至11岁的各年龄组中未发现性别差异。然而，在12至18岁年龄组中，女生的患病率显著高于男生。小学生、中学生和高中生的睡眠不足患病率分别为66.6%、74.1%和93.8%。9至12岁儿童和13至18岁青少年的患病率均随年龄增长。睡眠不足患病率最低的三个省份是浙江（68.8%）、江苏（66.7%）和陕西（65.2%）。逻辑回归模型的数据显示，与那些每天体育锻炼时间<0.5小时的学生相比，每天锻炼0.5 - 1小时（=0.72，95%置信区间：0.69 - 0.74）或≥1小时（=0.46，95%置信区间：0.44 - 0.47）似乎是睡眠不足的保护因素。与每周体育锻炼频率<2次相比，每周锻炼2次（=0.82，95%置信区间：0.78 - 0.86）或>2次（=0.65，95%置信区间：0.62 - 0.68）的频率也表现出保护作用。在中国，9至18岁学生中睡眠不足的患病率很高。我们的数据呼吁采取有效措施来应对这种情况。
