Abstract: 【Objective】 To understand sleep time and the prevalence of sleep disorders about migrant preschool children in Changning district, and to explore the influencing factors of sleep disorders. 【Methods】 550 migrant preschool children were selected with multi-phase sampling. Their parents or fosters were interviewed with general and sleep health questionnaire. 【Results】 The mean sleep time was (11.19±1.22) hours usually and only (10.87±1.37) hours on weekend about migrant preschool children. The sleep time of 3~4 years old children was shorter than foreign children,and the sleep time of 5 years old children on weekend was less than the standard. The difference of sleep time between boys and girls was not significant. The sleep time was different among different age groups. The prevalence of sleep disorders was 50.30%, in which the prevalence of boys was 50.88%, and the girls was 49.53%, the difference between them was not statistically significant (χ²= 0.089,P>0.05). The factors affecting sleep time and the prevalence of children were violent activities in the bedtime, sleeping habits of parents and other factors. 【Conclusions】 Sleep time of migrant preschool children in Changning district is relatively less and the prevalence of sleep disorders is higher compared to the existing data, which should be paid to a good attention.

摘要： 【目的】 了解长宁区非户籍学龄前儿童睡眠时间及睡眠障碍检出率,探讨非户籍学龄前儿童睡眠时间和睡眠障碍的影响因素。 【方法】 采用多阶段抽样方法纳入研究对象,使用自编的一般情况问卷、参考上海儿童医学中心编制的“儿童睡眠健康问卷”进行现场问卷调查。 【结果】 长宁区非户籍学龄前儿童平时睡眠总时间(11.19±1.22) h,周末睡眠总时间(10.87±1.37) h,3~4岁儿童睡眠时间及5岁儿童周末睡眠时间均少于国外标准,不同性别之间睡眠时间差异无统计学意义。不同年龄儿童睡眠时间差异有统计学意义(P<0.05)。495名非户籍学龄前儿童睡眠障碍检出率达50.30%,其中男童为50.88%,女童为 49.53%,两者差异无统计学意义(χ²= 0.089,P>0.05 )。儿童睡眠时间和睡眠障碍阳性检出率受到儿童睡前是否有剧烈活动、父母亲及抚养人睡眠习惯等诸多因素的影响。 【结论】 长宁区非户籍学龄前儿童睡眠时间不足,睡眠障碍阳性检出率高,睡眠质量应引起关注。
