Abstract Objective To investigate the prevalence of sleep problems and executive function difficulties in Shanghai preschoolers, and explore the relationship between them. Methods Based on the Shanghai Children’s Health, Education and Lifestyle Evaluation-Preschool （SCHEDULE-P） large population cohort study, 991 preschoolers were included in the analysis. Their parents finished children’s sleep habits questionnaire （CSHQ） and behavior rating scale of executive function-preschool （BRIEF-P）. Results The average age of the 991 preschoolers was （6.18±0.29） years, and boys accounted for 52.1%. The prevalence of total sleep problems was 48.6%, mainly containing delayed sleep onset and insufficient sleep duration. The prevalence of general executive function difficulties was 8.7%, which mainly included shift and emotional control problems. Children with general executive function difficulties were more likely to have total sleep problems （χ2=7.61, P<0.01） with 2.06 times higher than those of the normal children （95%CI: 1.22-3.48）. Different dimensions of executive function difficulties were associated with different sleep problems. Conclusion Sleep problems in preschoolers are closely related to executive function difficulties, which suggests that targeted comprehensive intervention should be carried out.
