To analyze the relationship between insufficient sleep and obesity or central obesity in Chinese Han children and adolescents aged 9-18 years. A total of 172 710 students who participated in the 2014 Chinese National Survey on Students Constitution and Health with complete data of sleep duration and physical examination, were selected as study subjects. Insufficient sleep was defined, according to the amount of sleep for pediatric populations recommended by the American Academy of Sleep Medicine. Obesity and central obesity of children and adolescents were judged by experts from the Group of China Obesity Task Force and Health Industry Standards in China. Differences between groups were compared by using the t test or (2) test. Logistic regression method was applied to assess the relationship between insufficient sleep and obesity or central obesity. In 2014, numbers of students with insufficient sleep, obesity and central obesity among Chinese Han children and adolescents aged 9-18 years appeared as 133 410 (77.2), 11 145 (6.5), and 12 603 (17.8), respectively. Among the students with insufficient sleep, 8 358 (6.3) were with obesity and 12 244 (17.9) were with central obesity. The prevalence of obesity and central obesity among boys with insufficient sleep was higher than that in girls. Pupils with insufficient sleep showed the highest prevalence of obesity and central obesity. After controlling for potential confounders, the risk of obesity appeared an increase of 14.5 (=1.145, 95: 1.092-1.200) and the risk of central obesity increased by 12.7 (=1.127, 95: 1.078-1.178) in students with insufficient sleep, when compared with those with adequate sleep. Compared with those whose daily sleep duration was less than 6 hours, the ones who slept 7-10 hours per day showed significantly reduction on the risk of obesity and central obesity in students. Insufficient sleep significantly increase the risk of obesity and central obesity in children and adolescents while adequate sleep of 7-10 hours per day would reduce the risk of obesity and central obesity in students.
分析9至18岁中国汉族儿童及青少年睡眠不足与肥胖或中心性肥胖之间的关系。选取2014年中国学生体质与健康调研中172710名睡眠时长和体检数据完整的学生作为研究对象。根据美国睡眠医学会推荐的儿童群体睡眠时间来定义睡眠不足。中国肥胖问题工作组及中国卫生行业标准的专家对儿童及青少年的肥胖和中心性肥胖进行判定。采用t检验或卡方检验比较组间差异。应用逻辑回归方法评估睡眠不足与肥胖或中心性肥胖之间的关系。2014年，9至18岁中国汉族儿童及青少年中睡眠不足、肥胖和中心性肥胖的学生人数分别为133410名（77.2%）、11145名（6.5%）和12603名（17.8%）。在睡眠不足的学生中，8358名（6.3%）患有肥胖，12244名（17.9%）患有中心性肥胖。睡眠不足的男生中肥胖和中心性肥胖的患病率高于女生。睡眠不足的小学生肥胖和中心性肥胖的患病率最高。在控制潜在混杂因素后，与睡眠充足的学生相比，睡眠不足的学生肥胖风险增加14.5%（比值比=1.145，95%置信区间：1.092至1.200），中心性肥胖风险增加12.7%（比值比=1.127，95%置信区间：1.078至1.178）。与每天睡眠时间少于6小时的学生相比，每天睡眠7至10小时的学生肥胖和中心性肥胖风险显著降低。睡眠不足会显著增加儿童及青少年肥胖和中心性肥胖的风险，而每天7至10小时的充足睡眠会降低学生肥胖和中心性肥胖的风险。
