Abstract: Objective To examine the association between mental health problems and sleep habits among Chinese adolescents,including sleep duration,bed time,wake time on weekdays and weekends,and sleep stability,in order to provide reference for prevention and improving mental health of adolescents. Methods A method of stratified,cluster random sample was conducted,and totally 4 966 adolescents aged 11~20 years were enrolled in this cross-sectional survey.The Modified Adolescent Sleep Hygiene Scale (M-ASHS) was used to assess sleep habits.The Strengths and Difficulties Questionnaire (SDQ) was used to evaluate mental health problems. Results Among adolescents involved in the survey,of whom 46.4% had a sleep duration less than 8 hours on weekdays,7.6% had a sleep duration less than 8 hours on weekends,47.5% had bed time later than 22:00 on weekdays,39.8% had bed time later than 22:30 on weekends,45.2% had awakening time later than 8:00 on weekends,22.55% had irregular sleep schedule;8.7% of the sampled adolescents had mental health problems.After controlling for confounders,five sleep variables were found to be associated with adolescents' mental health.The five factors covered three sleep domains:sleep duration less than 8 hours on weekdays and weekends (OR=1.77,1.65,95%CI:1.13~2.76,1.12~2.43,P=0.012,0.011),bed time later on weekdays and weekends (OR=1.73,1.37,95%CI:1.30~2.31,1.07~1.77,P<0.001,P=0.014),and irregular sleep schedule (OR=1.48,95%CI:1.08~2.02,P=0.014). Conclusion It is suggested that sleep hygiene education should be strengthened to help adolescents develop good sleep habits,including enough sleep duration,early to bed and wake up earlier,and regular sleep schedule,in order to promote prevention and intervention of mental health problems.
