Abstract: Objective To analyse the sleep time,the prevalence and the risk factors of sleep disorders in children with allergic diseases of 3~6 years old in Nanjing,and to provide evidence for the prevention and intervention of sleep disorders.

摘要： 目的 分析南京市3～6岁健康儿童及患过敏性疾病儿童睡眠时间、睡眠障碍发生状况及相互关系,为预防和干预儿童睡眠问题提供依据。方法 采用分层整群抽样方法,应用自制学龄前儿童睡眠状况调查问卷,对1 432名3～6岁儿童进行调查。结果 南京市学龄前儿童平均每天睡眠时间(10.74±0.85)h,明显低于国内外同年龄段儿童基本需求标准,患过敏性鼻炎及哮喘儿童睡眠时间明显比健康儿童短(P<0.05);儿童睡眠障碍总发生率为52.7%,患哮喘及过敏性鼻炎儿童睡眠障碍的发生率分别为68.3%和66.5%。结论 南京市学龄前儿童睡眠时间不足,睡眠质量差,睡眠问题的发生率较高,过敏性疾病可能是睡眠障碍发生的高危因素,应引起社会及家长的重视。
