Abstract

Objective

Although sleep habits are associated with the development of toddlers, factors affecting social development and brain function remain unclear. We aimed to elucidate the relationship between sleep habits and social development as well as brain coherence in toddlers.

Methods

We used the data set at 1.5–2 years old, in the longitudinal study until 6 years old. We evaluated sleep parameters, such as average wake-up time, bedtime, nighttime sleep duration, total sleep duration, and the standard deviation (SD) of sleep habits. We also examined the development, including the social stimuli fixation percentage using Gazefinder® and electroencephalography (EEG) coherence between brain regions.

Results

Seventy-two children (37 boys and 35 girls) were included. The fixation percentage for the human face was negatively correlated with the SD of the total sleep duration, nighttime sleep duration, nap duration, and bedtime (r = −0.516, p = 0.000; r = −0.331, p = 0.005; r = −0.330, p = 0.005; and r = −0.324, p = 0.005, respectively). The EEG analysis indicated that α-band coherence in the right centro-parietal area was negatively correlated with the total sleep duration (r = −0.283, p = 0.016). The path diagram demonstrated a direct significant effect of sleep duration irregularity on development including social communication and fixation percentage for human faces. Additionally, total sleep duration exhibited a direct effect on α cortical coherence in the right centro-parietal area.

Conclusions

In this study, we found an association between sleep irregularity and the development of social communication, preference for humans, and brain coherence in toddlers. We suggest that regular sleep plays an important role in promoting the development of social communication.

幼儿有规律的睡眠习惯与社交发展和大脑协调性有关。

目的：虽然睡眠习惯与幼儿的发育有关，但影响幼儿社会性发育和大脑功能的因素仍不清楚。我们旨在阐明幼儿的睡眠习惯与社会性发展以及大脑连贯性之间的关系：方法：我们在纵向研究中使用了幼儿 1.5-2 岁时的数据集，直至幼儿 6 岁。我们评估了睡眠参数，如平均起床时间、就寝时间、夜间睡眠时间、总睡眠时间以及睡眠习惯的标准偏差（SD）。我们还研究了儿童的发育情况，包括使用 Gazefinder® 测定社交刺激物的固定百分比和脑区之间的脑电图（EEG）连贯性：结果：72 名儿童（37 名男孩和 35 名女孩）参加了此次研究。人脸的固定百分比与总睡眠时间、夜间睡眠时间、午睡时间和就寝时间的 SD 值呈负相关（r = -0.516，p = 0.000；r = -0.331，p = 0.005；r = -0.330，p = 0.005；r = -0.324，p = 0.005）。脑电图分析表明，右侧中央顶叶区的α波段相干性与总睡眠时间呈负相关（r = -0.283，p = 0.016）。路径图显示，睡眠时间不规律对社交沟通和人脸固定百分比等发育有直接显著影响。此外，总睡眠时间对右侧中央顶叶区的α皮质连贯性也有直接影响：在这项研究中，我们发现睡眠不规律与幼儿的社会交流发展、对人类的偏好和大脑连贯性之间存在关联。我们认为，规律的睡眠在促进幼儿社会交往能力的发展方面发挥着重要作用。

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.
