关于中国广州城市儿童睡眠时间与肥胖之间关系的信息有限。本研究旨在研究6-18岁儿童睡眠时间与肥胖之间的关系。样本包括11,830名6-18岁的儿童。这些孩子是从广州三个城区的13所学校中随机抽取的。该研究于2013年9月至11月进行。测量了孩子们的身高和体重。根据体质指数和中国标准的切点估计肥胖状况。在结构化问卷中，儿童报告了每日睡眠时间（少于7小时、7 - 9小时和超过9小时）、每周食物摄入量（包括蔬菜、水果、含糖饮料和肉类）、身体活动和久坐时间。看护人将代表九岁以下的孩子回答问卷。共有8760名儿童（49.0%为男孩）完成了这项研究。肥胖患病率为8.4%（男孩9.8%，女孩5.7%）。调整年龄、饮食和身体活动/久坐行为后，男孩中睡眠<7小时（短睡眠时间，SSD）与≥9小时（长睡眠时间，LSD）的肥胖比值比（OR）为0.70 (95% CI: 0.69-0.72)，女孩中为1.73 （95% CI: 1.71-1.74）。按年龄分层，6-12岁男孩SSD与LSD的OR为0.60 (95% CI: 0.55-0.66)；相比之下，13-18岁男孩的OR为1.33 （95% CI: 1.30-1.37）。在女孩和13- 18岁的男孩中，睡眠时间短与肥胖的几率增加有关，但在6- 12岁的男孩中，肥胖的几率会降低。短睡眠对肥胖的影响应视年龄和性别为具体特征。
Information on the relationship between sleep duration and obesity among children in urban Guangzhou, China is limited. This study aims to examine the relationship between sleep duration and obesity in children aged 6–18 years. The sample consisted of 11,830 children aged 6–18 years. The children were randomly selected from 13 schools in three urban districts of Guangzhou. The study was conducted from September to November 2013. The height and weight of the children were measured. Adiposity status was estimated using body mass index and according to the cut point in China criteria. In the structured questionnaire, children reported daily sleep hours (less than 7 h, 7–9 h and more than 9 h), weekly food intake amount (including vegetables, fruit, sugar beverages and meat), physical activity and sedentary time. A caretaker would answer the questionnaire on behalf of a child aged below nine. A total of 8,760 children (49.0 % boys) completed the study. The prevalence of obesity was 8.4 % (9.8 % in boys and 5.7 % in girls). Adjusted for age, diet and physical activity/sedentary behaviour, the odds ratio (OR) for obesity comparing sleeping <7 h (short sleep duration, SSD) with ≥9 h (long sleep duration, LSD) was 0.70 (95 % CI: 0.69–0.72) among boys and 1.73 (95 % CI: 1.71–1.74) among girls. Stratified by age, OR for boys aged 6–12 years comparing SSD with LSD was 0.60 (95 % CI: 0.55–0.66); by contrast, OR was 1.33 (95 % CI: 1.30–1.37) for boys aged 13–18 years. Short sleep duration is associated with increased chances of obesity among girls and 13- to 18-year-old boys, but the chances of obesity are decreased among 6- to 12-year-old boys. Age and gender should be regarded as specific characteristics for the effects of short sleep on obesity.
