研究目的：以前的研究对亚洲和西方国家儿童睡眠问题的差异进行了跨文化比较。然而，这种差异是否能在亚洲国家之间观察到，目前尚不清楚。本研究旨在调查日本和中国学龄前儿童睡眠问题模式的差异。方法：数据收集自日本1个城市和中国10个城市。本研究招募了438名日本和1020名中国4岁和5岁的学龄前儿童。睡眠问题和模式进行了评估的基础上，父母的报告，使用儿童的睡眠习惯问卷（CSHQ）。结果：协方差分析显示，日本和中国学龄前儿童之间的总CSHQ分数没有显着差异，从而表明，睡眠问题的总的严重程度并没有组间差异。日本学龄前儿童在CSHQ的就寝阻力分量表上的得分高于中国学龄前儿童。相反，中国学龄前儿童表现出较高的夜间觉醒和睡眠呼吸障碍的子量表得分。此外，日本学龄前儿童表现出较早的bedtimes和唤醒时间和较短的总睡眠时间比中国学龄前儿童.Conclusions：我们的研究结果表明，在日本和中国之间的学龄前儿童的睡眠问题的模式不同，这种差异可能是由于在cosleeping的做法，睡前例程，和/或环境条件的差异。因此，研究学龄前儿童睡眠的研究人员应该考虑睡眠问题模式的区域差异，即使是在亚洲国家。(C)2018 Elsevier B.

Study objectives: Previous studies have performed cross-cultural comparisons of differences in childhood sleep problems between Asian and Western countries. However, whether such differences can be observed among Asian countries remains unclear. The present study aimed to investigate differences in the pattern of sleep problems between Japanese and Chinese preschoolers.Methods: Data were collected from one city in Japan and 10 cities in China. The present study recruited 438 Japanese and 1020 Chinese preschoolers aged four and five years. Sleep problems and patterns were assessed on the basis of parental reports using the Children's Sleep Habits Questionnaire (CSHQ).Results: Analysis of covariance revealed no significant difference in total CSHQ scores between Japanese and Chinese preschoolers, thus indicating that the total severity of sleep problems did not differ between the groups. Japanese preschoolers exhibited higher scores on the bedtime resistance subscale of the CSHQ than Chinese preschoolers. Conversely, Chinese preschoolers exhibited higher subscale scores for night wakings and sleep-disordered breathing. In addition, Japanese preschoolers exhibited earlier bedtimes and wake times and shorter total sleep times than Chinese preschoolers.Conclusions: Our findings indicate that the patterns of sleep problems in preschoolers differ between Japan and China and that such differences may be due to differences in cosleeping practices, bedtime routines, and/or environmental conditions. Thus, investigators studying sleep in preschoolers should consider regional differences in the pattern of sleep problems, even among Asian countries. (C) 2018 Elsevier B.V. All rights reserved.
