ABSTRACT
Objective@#To investigate the general situation of sleep duration, sleep quality and related risk factors among primary students in Shanghai and to provide evidence for the prevention and control of students sleep health.@*Methods@#By using stratified cluster random sampling method, 3 410 students from 16 primary schools in four urban areas and four suburb areas of Shanghai were selected to conduct sleep health questionnaire survey and physical examination Chi square test was used for group comparison while binary Logistic regression was used to assess possible factors related with sleep quality.@*Results@#The detection rate of sleep insufficiency (<10 h) among students was 93.0%. The detection rate of poor sleep quality was 66.8% with 67.1% in girls and 66.6% in boys. The top three sleep problems were daytime sleepiness(80.9%), irregular sleep duration (74.1%) and sleep anxiety(59.5%). Multivariate Logistic regression analysis showed that everyday moderate-intensity physical activity (OR=1.51, 95%CI=1.04-2.21) and daily walking activity (more than 10 minutes)(OR=1.27, 95%CI=1.08-1.50) were risk factors of poor sleep quality(P<0.05).@*Conclusion@#In Shanghai, the prevalence of sleep insufficiency and poor sleep quality among primary students are high. Sleep health was associated with moderate physical activity and walking activity. Increasing the duration of moderate physical activity and daily walking activity is the very important measures in prevention and control of the sleep problems.
