目的探究学龄前儿童睡眠与生活质量的相关性。方法采用分层整群抽样的方法,在上海市虹口区随机抽取11所幼儿园,对其5~7岁儿童进行调查。采用个人及家庭社会环境问卷,中文版儿童睡眠习惯问卷(Children’Sleep Habits Questionnaire,CSHQ)、儿童生存质量测定量表系列中普适性核心量表(4.0)(The Pediatric Quality of Life Inventory Measurement Models,PedsQL)评估儿童个人基本信息、睡眠情况及儿童生活质量。结果入组儿童共836名,男生占49.9%。相比睡眠时间短(<-1s)的儿童,睡眠时间长(>+1s)的儿童有较高的总体生活质量、生理功能及情感功能。而睡眠节律模式较早(<-1s)的儿童也比睡眠节律较晚(>+1s)的儿童有较好的总体生活质量、生理功能、情感功能及在幼儿园的表现。结论学龄前儿童睡眠时间及睡眠节律模式与生活质量均显著相关。家长及教师应更加关注儿童的睡眠健康。 Objective To explore the correlation between preschool children’s sleep and quality of life.
