Abstract
Objectives
Evening-chronotype is associated with increased socioemotional problems among school-aged children. Inadequate sleep and increased sleep problems are also prevalent among evening-chronotype children and may underlie the relationship between chronotype and socioemotional problems. However, it is unclear whether the association between chronotype and socioemotional problems at school-age may be mediated by poorer sleep during late preschool.
Methods
Our study utilized cross-sectional data to examine the relations between chronotype, sleep duration, sleep problems and socioemotional problems in preschoolers. We subsequently performed longitudinal mediation analyses to examine how the association between chronotype at preschool-age and later socioemotional problems at school-age may be mediated by sleep problems and sleep duration during late preschool. 399 children from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) birth cohort study were included for analyses. Children's chronotype were identified with the Children's Chronotype Questionnaire at 4.5 years old. Sleep duration and problems were measured with the Children's Sleep Habits Questionnaire at 4.5 and 6 years old. Socioemotional problems were evaluated using the Child Behavioral Checklist at 4 and 7 years of age. All questionnaires were caregiver-reported.
Results
Linear regressions demonstrated that eveningness was associated with concurrent sleep problems and internalizing, externalizing and total behavioral problems at 4–4.5 years old, but not sleep duration. Mediation analyses supported that sleep problems (and not sleep duration) at 6 years old mediated the relationship between chronotype and socioemotional problems at 7 years old.
Conclusions
Our findings suggest addressing sleep problems during early development may reduce socioemotional problems at school-age, especially among evening-chronotype children.
期刊介绍：
Sleep Medicine aims to be a journal no one involved in clinical sleep medicine can do without.
A journal primarily focussing on the human aspects of sleep, integrating the various disciplines that are involved in sleep medicine: neurology, clinical neurophysiology, internal medicine (particularly pulmonology and cardiology), psychology, psychiatry, sleep technology, pediatrics, neurosurgery, otorhinolaryngology, and dentistry.
The journal publishes the following types of articles: Reviews (also intended as a way to bridge the gap between basic sleep research and clinical relevance); Original Research Articles; Full-length articles; Brief communications; Controversies; Case reports; Letters to the Editor; Journal search and commentaries; Book reviews; Meeting announcements; Listing of relevant organisations plus web sites.
