There is emerging evidence that sleep problems in childhood may have enduring consequences. Studies using parental and objective sleep measurement suggest that sleep difficulties in children may be associated with behavioural problems. However, the findings using objective sleep measures are inconsistent and it is not clear what aspects of sleep quality are associated with daytime behavioural difficulties. The aim of this paper is to identify which behavioural symptoms are best predicted by actigraphic sleep measures in a general population sample of school-aged children aged 6-11 years.
Actigraphy was used to measure sleep in 91 typically developing children aged 6-11 years for 6 days. Parents completed the Strengths and Difficulties Questionnaire (SDQ). A series of multivariate linear regression models were computed to analyse the effects of sleep on SDQ subscales.
Sleep did not predict emotional symptoms or hyperactivity. After controlling for age and gender, sleep accounted for 18% of the variance in conduct problems. Only actual sleep time in minutes made a significant contribution to the model.
A child who sleeps 1 h less than the average child may be at risk of conduct problems. Clinicians should consider routinely screening for sleep difficulties when assessing children with conduct problems.
越来越多的证据表明，儿童期睡眠问题可能会产生持久影响。使用父母报告和客观睡眠测量方法的研究表明，儿童睡眠困难可能与行为问题有关。然而，使用客观睡眠测量方法得出的结果并不一致，目前尚不清楚睡眠质量的哪些方面与日间行为困难相关。本文旨在确定在6至11岁学龄儿童的一般人群样本中，哪些行为症状能通过活动记录仪测量的睡眠指标得到最佳预测。
采用活动记录仪对91名6至11岁发育正常的儿童进行为期6天的睡眠测量。父母完成优势与困难问卷（SDQ）。计算一系列多元线性回归模型，以分析睡眠对SDQ分量表的影响。
睡眠不能预测情绪症状或多动。在控制年龄和性别后，睡眠占品行问题方差的18%。只有以分钟为单位的实际睡眠时间对模型有显著贡献。
睡眠时间比平均水平少1小时的儿童可能存在品行问题风险。临床医生在评估有品行问题的儿童时，应考虑常规筛查睡眠困难情况。
