ABSTRACT
Objeetive@#To learn the sleep behaviors of preschool children and their association with behavioral problems,so as to provide reference for improving sleep quality and behaviors in preschool children.@*Methods@#By stratified random sampling method,the children aged 3-6 years were selected from 11 counties in 5 cities of Zhejiang Province. A self-designed questionnaire was used to investigate 19 items of sleep behaviors, and Achenbach children's behavior Scale（CBCL）was used to evaluate behavior problems. Spearman rank correlation was conducted to analyze the relationship between sleep behaviors and behavioral problems in preschool children. @*Results @#Totally 1 865 preschool children were enrolled,1 732 valid questionnaires were collected,with a response rate of 92.86%. The total score of sleep behaviors in preschool children was 5.87±3.38. The prevalence rates of 19 sleep behaviors ranged from 0.69% to 82.85%;the common behaviors were rejecting quilt cover（82.85%）,grinding teeth（53.35%）,sleep-talking（53.23%）,drooling（52.66%）and snoring（43.07%）. The total score of CBCL was 20.01±14.39. There were 229 children with behavioral problems,accounting for 13.22%. The results of Spearman rank correlation showed that except for sleeping posture and apnea,all the other 17 items of sleep behaviors were correlated with the total score of CBCL（P < 0.05）. @*Conclusion@#Preschool children generally have problems in sleep, their sleep behaviors are correlated with behavioral problems.
