Emotional problems such as anxiety and low mood have been associated with sleep problems in children. The study's objectives were to 1) assess the association between sleep duration and internalizing symptoms (anxiety and low mood) in children aged 5-12 years (y), and 2) evaluate whether insufficient sleep according to the National Sleep Foundation (NSF) guidelines is associated with internalizing symptoms.
A cross-sectional study of N =796 children aged 5-12y, recruited from primary care physicians' offices in Toronto, Canada was conducted through the TARGet Kids! research network. Using linear regression, we investigated 1) the cross-sectional association between parent reported 24-hour sleep duration (hours) and parent reported symptoms using the Strengths and Difficulties Questionnaire (SDQ), controlling for child age, sex, family income, maternal education, family composition, and standardized body-mass index (zBMI). The analysis was repeated using insufficient sleep per NSF guideline as the independent variable.
Sleep duration was inversely associated with internalizing symptoms, B estimate = -0.33 (95%CI -0.57, -0.07), p=0.012. Twenty-eight (14%) children aged 5 y, and 36 (6%) of those aged 6-12y, experienced insufficient sleep. There was a trend toward association between insufficient sleep and internalizing symptoms, B estimate = 0.64 (-0.09, 1.38), p=0.086.
The relationship between insufficient sleep and internalizing symptoms among children requires further elucidation. Children who show internalizing symptoms may benefit from interventions supporting sleep.
焦虑和情绪低落等情绪问题与儿童睡眠问题有关。本研究的目的是：1）评估5至12岁儿童的睡眠时间与内化症状（焦虑和情绪低落）之间的关联；2）评估根据美国国家睡眠基金会（NSF）指南确定的睡眠不足是否与内化症状有关。
通过TARGet Kids!研究网络，对从加拿大多伦多的初级保健医生办公室招募的796名5至12岁儿童进行了一项横断面研究。我们使用线性回归，1）研究了父母报告的24小时睡眠时间（小时）与父母使用优势与困难问卷（SDQ）报告的症状之间的横断面关联，同时控制儿童年龄、性别、家庭收入、母亲教育程度、家庭构成和标准化体重指数（zBMI）。以NSF指南定义的睡眠不足作为自变量重复进行该分析。
睡眠时间与内化症状呈负相关，B估计值=-0.33（95%CI -0.57，-0.07），p=0.012。28名（14%）5岁儿童和36名（6%）6至12岁儿童存在睡眠不足。睡眠不足与内化症状之间存在关联趋势，B估计值=−0.64（−0.09，1.38），p=0.086。
儿童睡眠不足与内化症状之间的关系需要进一步阐明。表现出内化症状的儿童可能会从支持睡眠的干预措施中受益。
