Abstract

BACKGROUND

Several environmental factors affect sleep. We investigated the sleep and sleep-related habits of preschool children living in Tibet and conducted an international comparison with those in Japan.

METHODS

We conducted a community-based cross-sectional study using the Chinese version of the Japanese Sleep Questionnaire for Preschoolers (JSQ-P-C) and compared the results with previous data on Japanese children.

RESULTS

The sleep status of 3113 children aged 3-6 years old in Qinghai province was evaluated. The average wake time and bedtime of the Tibetan children were 7:20 ± 0:31 and 21:16 ± 0:43, respectively. Their mean nocturnal sleep duration was 10.0 ± 0.7 h. In comparing 3-year-old children, the time for which they viewed TV in Tibet was shorter (65.5 ± 44.6 min) than that in Japan (149.7 ± 76.6 min), and the mother's bedtime was earlier in Tibet (21:28 ± 2:14) than in Japan (23:20 ± 1:05). However, the bedtime and sleep duration of the Tibetan children (21:17 ± 0:37 and 10.0 ± 0.7 h) were fairly similar to those of the Japanese children (21:24 ± 1:57 and 9.8 ± 0.8 h).

CONCLUSIONS

The late bedtime and short nocturnal sleep duration of Tibetan toddlers were the same as those of Japanese toddlers despite considerable differences in their lifestyle and environment.

摘要

背景

多种环境因素会影响睡眠。我们调查了居住在西藏的学龄前儿童的睡眠及与睡眠相关的习惯，并与日本的学龄前儿童进行了国际比较。

方法

我们使用日语版学龄前儿童睡眠问卷的中文版（JSQ-P-C）进行了一项基于社区的横断面研究，并将结果与日本儿童的先前数据进行了比较。

结果

对青海省3113名3至6岁儿童的睡眠状况进行了评估。藏族儿童的平均起床时间和就寝时间分别为7:20 ± 0:31和21:16 ± 0:43。他们的平均夜间睡眠时间为10.0 ± 0.7小时。在比较3岁儿童时，他们在西藏看电视的时间（65.5 ± 44.6分钟）比在日本（149.7 ± 76.6分钟）短，而且在西藏母亲的就寝时间（21:28 ± 2:14）比在日本（23:20 ± 1:05）早。然而，藏族儿童的就寝时间和睡眠时间（21:17 ± 0:37和10.0 ± 0.7小时）与日本儿童（21:24 ± 1:57和9.8 ± 0.8小时）相当相似。
