新冠肺炎疫情居家隔离期托幼儿童睡眠习惯研究——以南京市区为例

On Sleeping Habit of Preschool Children during Home Quarantine Period of COVID-19 Epidemic——Taking Nanjing as an Example

目的以南京市区为例,比较托幼儿童新冠肺炎疫情居家隔离期前后睡眠变化情况,为特殊时期托幼儿童睡眠指导提供依据,也为幼儿园复学准备提供支持。方法采用分层整群抽样法,抽取南京市区4所幼儿园共1743名在园儿童家长进行网络问卷调查,比较疫情居家隔离期托幼儿童睡眠习惯及时间变化情况。结果疫情居家隔离期托幼儿童睡眠习惯较疫情前有所改变,居家隔离期夜间睡觉时间及早晨起床时间均有所延后,夜间睡眠时长改变呈"两头分布",即睡眠不足8小时和超过10小时儿童较疫情前增多,午睡时长不足1小时儿童较疫情前也有明显增加,其差异具有统计学意义;各年级儿童夜间睡觉时间段虽无明显差异,但早晨起床时间、夜间睡眠时长、午睡时长差异显著。结论南京市区学龄期儿童在疫情居家隔离期间,睡眠习惯较疫情前有所改变,不同年级儿童睡眠习惯也有不同。

Objective Comparing changes of sleeping habits before and after the COVID-19 epidemic among pre⁃school children in Nanjing,we provide guidance for children to sleep in special period as well as support for the school resumption.Methods By means of stratified cluster sampling,a total of 1743 parents of children in 4 kin⁃dergartens were sampled to compare the changes of sleep habits and time of children in quarantine period.Result The sleeping habits of children in the quarantine period were changed compared with those before the epidemic.To be more specific,the time of going to bed at night and getting up in the morning were delayed during the pe⁃riod of home isolation.The variance of sleep time at night showed a“distribution at both ends”.More children slept less than 8 hours and more than 10 hours than before the outbreak,and more children were taking naps of less than an hour than before the outbreak,which was statistically significant.There was no significant difference in the time of sleeping at night among children in different grades,while there were significant differences in the time of getting up in the morning,night sleep duration and nap duration.Conclusion The sleeping habits of school-age children in Nanjing were different from those before the epidemic,and the sleeping habits of chil⁃dren in different grades were different.
