杭州市学龄前儿童的日间功能及其与睡眠质量的相关性研究

目的：了解杭州市学龄前儿童的日间功能、睡眠质量及其相关性。方法采取整群抽样的方法抽取杭州市5所幼儿园儿童共930例，采用一般情况问卷、儿童睡眠习惯问卷（CSHQ）及幼儿日间功能问卷收集资料，分析不同年龄、性别儿童的睡眠质量，及不同睡眠质量的儿童的日间功能表现。结果共914例3-6岁儿童纳入分析。42.0%（384/914）儿童存在睡眠质量不良，其中3-岁组儿童睡眠不良发生率明显高于其他年龄组（P＜0.05），无性别差异（P＞0.05）。日间功能总得分随年龄增长逐渐下降，不同年龄组之间差异有统计学意义（P＜0.01）。白天倦怠、难以完成工作情况在不同年龄组之间差异有统计学意义（P＜0.01），负性情绪及明显多动情况在各年龄组之间差异无统计学意义（P＞0.05）。睡眠质量良好组日间功能总得分及各分项得分均低于睡眠质量不良组，两组在总得分及完成工作上差异有统计学意义（均P＜0.05）。结论睡眠质量不良的学龄前儿童的日间功能较差，主要表现为白天难以完成工作。
