Abstract: Objective To investigate the association between sleep and life quality among preschool children. Methods A stratified, clustered sampling design was used to select subjects aged 5~7 years old from 11 kindergartens in Hongkou district, Shanghai, China.The Socio-demographic questionnaire, Children Sleep Habits Questionnaire (CSHQ)and Pediatric Quality of Life Inventory Measurement Models (PedsQL4.0) were used to assess children's basic information, sleep as well as life quality. Results The final sample consisted of 836 children, boys accounted for 49.9%.Compared to short sleepers (<-1s), children with longer sleep duration (>+1s) had better overall life quality, physical and emotional function, and those who had earlier chronotype(<-1s) showed better overall life quality, physical function, emotional function and performance in the kindergarten than later chronotype (>+1s).
