Abstract: Objective To investigate sleep problems and the associated factors among preschool children during home quarantine, so as to provide scientific basis for minimizing the impact of restricted activities and home isolation resulting from public health emergency on children's health. Methods An online survey was conducted from March 15th to 28th, 2020 among 16 094 children aged 3 to 6 years.The parents of children completed the Children's Sleep Habits Questionnaire (CSHQ), the Children Strengths and Difficulties Questionnaire (SDQ) (edition for parents).The data together with their demographic information were collected and analyzed. Results The prevalence of sleep problems (CSHQ score>41) was 76.8%, which was significantly correlated with socio-demographic factors including age, parents' education level, family structure and so on (χ²=66.98, 36.51, 11.01, P<0.05).After controlling for socio-demographic factors, children with more severe emotional/behavioral problems were at higher risk of sleep disturbance. Conclusions Sleep problems among preschoolers are common during home quarantine caused by public health emergency, and are associated with emotional/behavioral problems.Targeted interventions are needed to minimize the impact of restricted activities and home quarantine on children's health.

摘要： 目的 分析学龄前儿童居家隔离期间的睡眠问题及影响因素,为降低因突发性公共卫生事件而居家隔离和限制活动对儿童健康的影响提供科学依据。方法 2020年3月15-28日对16 094名3~6岁儿童进行在线调查。由家长填写一般资料、标准中文版儿童睡眠习惯问卷(CSHQ)以及长处和困难问卷(SDQ),收集儿童睡眠及情绪/行为相关数据。结果 学龄前儿童睡眠问题的发生率为76.8%(CSHQ总分＞41),与年龄、家长受教育程度及家庭类型等人口社会学因素显著相关(χ²=66.98、36.51、11.01, P＜0.05)。控制人口社会学因素后,情绪/行为问题越严重的儿童,睡眠问题的发生风险越高。结论 疫情期间学龄前儿童睡眠问题普遍存在,与儿童情绪/行为问题相关,应当进行综合干预,从而将因疫情而居家隔离和限制活动对儿童健康的影响降至最低。
