ABSTRACT

Objectives/Background

Correlational studies show that short sleep is associated with negative daytime outcomes in school-aged children, but there are few experimental sleep manipulation studies to assess whether this is a causal relation. The aim of this study was to determine the impact of mild, cumulative sleep restriction on daytime functioning of typically developing (TD) children and children with attention-deficit/hyperactivity disorder (ADHD).

Participants

A total of 36 school-aged children (n = 18 TD; n = 18 ADHD), aged 6–11 years participated.

Methods

Children participated in two sleep conditions (order counter-balanced). The Restricted condition required a 1 h reduction of time in bed for one week, and the Controlled Typical condition was based on participant’s average baseline sleep. At the end of each condition, participants attended the sleep lab for overnight polysomnography and daytime functioning assessments.

Results

Children successfully reduced time in bed by ~1 h. Due to compensatory changes, total sleep time (TST) was reduced by only ~20 min, as children fell asleep faster and spent less time awake after sleep onset during the Restricted compared to Controlled Typical condition. Many daytime functions were not affected by this very mild sleep restriction, however, both groups showed significant changes in performance on an objective attention task and on a parent-rated emotional lability measure after six nights of minimal reductions in TST. There were no significant differences between groups.

Conclusions

Results suggest that a very mild sleep restriction can affect children’s attention and emotional regulation, even with evidence of compensatory sleep mechanisms.

即使是轻微的睡眠限制也会影响多动症儿童及其正常发育的同龄人的日间功能

摘要

目标/背景

相关研究表明,短睡眠与学龄儿童的负面白天结果相关,但很少有实验性睡眠操纵研究来评估这是否是因果关系。本研究的目的是确定轻度、累积睡眠限制对正常发育 (TD) 儿童和注意力缺陷/多动障碍 (ADHD) 儿童日间功能的影响。

参与者

共有 36 名年龄在 6-11 岁的学龄儿童(n = 18 TD;n = 18 ADHD)参加了此次活动。

方法

儿童参与了两种睡眠条件(顺序平衡)。受限条件需要在一周内减少 1 小时的卧床时间,而受控典型条件基于参与者的平均基线睡眠。在每个条件结束时,参与者参加睡眠实验室进行夜间多导睡眠图和白天功能评估。

结果

儿童成功地将卧床时间减少了约 1 小时。由于代偿性变化,总睡眠时间 (TST) 仅减少了约 20 分钟,因为与受控典型条件相比,在受限条件下,儿童入睡更快,入睡后清醒时间更少。许多白天的功能并未受到这种非常轻微的睡眠限制的影响,但是,在 TST 最小减少六晚后,两组在客观注意力任务和父母评定的情绪不稳定性测量中表现出显着变化。组间没有显着差异。

结论

结果表明,即使有补偿性睡眠机制的证据,非常轻微的睡眠限制也会影响儿童的注意力和情绪调节。
