摘要
Sleep is vital for children's early socio-emotional development, particularly empathy. This study aimed to explore the associations between sleep and empathy in young preschoolers. A sample of 23,259 preschoolers (4.3 +/- 0.3 years) at the entry year of preschool was recruited as part of the Shanghai Children's Health, Education and Lifestyle Evaluation-Preschool (SCHEDULE-P) study. Caregivers reported on child sleep, affective empathy, and cognitive empathy through the Children's Sleep Habits Questionnaire and the Griffith Empathy Measure. Ordinary least-square regression and quantile regression were performed for the associations between sleep and empathy. Sex differences were also investigated. Night sleep duration was negatively associated with affective empathy (beta = -0.35, p < 0.001), and positively associated with cognitive empathy (beta = 0.41, p < 0.001). Longer nap duration was associated with higher affective empathy (beta = 0.28, p < 0.001). Sleep disturbances were positively associated with affective empathy (beta = 0.04, p < 0.001) and negatively associated with cognitive empathy (beta = -0.09, p < 0.001). These associations were generally stronger in children at higher empathy quantiles and also those at the 10(th) cognitive empathy quantile. The associations between sleep and affective empathy were mainly contributed by girls, and were more common in boys in terms of cognitive empathy, particularly at the 10(th) and the 30(th) quantiles. In conclusion, longer night sleep duration and fewer sleep disturbances are associated with a more mature empathy pattern in young preschoolers. The associations are more prominent in children at the higher end of the empathy spectrum, and vary by sex. These findings highlight the importance to promote sleep health in young children for optimal socio-emotional development.
