Abstract:Objective To describe the status of sleep duration in Chinese schoolchildren and explore its association with overweight and obesity.Methods A cross-sectional study of 1308 students from six primary schools in Beijing Municipality and Ningxia Autonomous Region was conducted in 2012, using a self-administered questionnaire. After adjusting the covariates including gender, age, region, breakfast and healthy diet score, a logistic regression was used to analyze the association between sleep duration and overweight and obesity.Results The sleep duration was 9.5±0.6h, 9.4±0.6h, or 9.9±0.8h on total average, workdays only or weekends only, respectively. A longer sleep duration on weekdays (OR= 0.794,95% confidence intervals:0.636~0.991,P=0.042) was associated with a lower risk of overweight and obesity among children.Conclusion Reduction in sleep duration may increase the risk of overweight and obesity among schoolchildren aged 6-10.
