Many children have periods when they sleep too little, with widely recognized detrimental effects. Less is known about persistent short sleep during childhood. Therefore, the present study aimed to investigate the prevalence of persistent short sleep in school-aged children and identify a set of child, parent, and peer predictors thereof.
Objectively measured sleep duration (hip-held accelerometer) was biennially assessed in a community sample followed from 6 to 14 years (n=801). A latent profile analysis was applied to assess whether a subgroup of children slept consistently short across time and predictors of persistent short sleep were determined through regression analysis.
A subgroup of children (n=160; 20.2%) was identified as having persistent short sleep across time. Temperamental negative affectivity (β=0.08; 95% CI=0.01, 0.15; p=0.03) and low observer-assessed parental emotional availability (β=-.09; 95% CI=-.18, -.01; p=0.04) predicted membership to that group. Teacher ratings of victimization from bullying were not associated with persistent short sleep (β=0.01; 95% CI: -.10, 11; p=0.88).
High child temperamental negative affectivity and low parental emotional availability may be involved in the development of persistent short sleep through childhood.
许多儿童都有睡眠过少的时期，其不良影响已广为人知。关于儿童期持续短睡眠的情况，人们了解得较少。因此，本研究旨在调查学龄儿童中持续短睡眠的患病率，并确定一系列与之相关的儿童、父母及同伴预测因素。
对一个从6岁到14岁的社区样本（n = 801）每两年进行一次客观测量的睡眠时间（髋部佩戴式加速度计）评估。应用潜在剖面分析来评估是否有一组儿童在不同时间持续睡眠短，并通过回归分析确定持续短睡眠的预测因素。
确定了一组儿童（n = 160；20.2%）在不同时间持续睡眠短。气质性消极情绪（β = 0.08；95%置信区间 = 0.01，0.15；p = 0.03）和观察者评估的父母情感可用性低（β = -0.09；95%置信区间 = -0.18，-0.01；p = 0.04）可预测该组的成员身份。教师对受欺凌受害情况的评分与持续短睡眠无关（β = 0.01；95%置信区间：-0.10，0.11；p = 0.88）。
儿童气质性消极情绪高和父母情感可用性低可能在儿童期持续短睡眠的发展中起作用。
