学龄前儿童运动与睡眠质量的关联研究

Study on the association between exercise and sleep quality in preschool children

目的分析学龄前儿童运动与睡眠质量的关系,探讨影响学龄前儿童睡眠质量的生命早期因素。方法 2018年3-6月以上海市登记注册的4所幼儿园833名3~6岁学龄前儿童为研究对象,对750名有效样本运动及睡眠状况进行分析。采用多因素非条件Logistic回归模型分析运动时间和运动项目与学龄前儿童睡眠质量的关系。结果学龄前儿童学习日、休息日运动时间较少比例分别占72.7%(545/750)、27.2%(204/750),参与散步者占73.5%(551/750)。睡眠质量好、中等、差分别占23.9%(179/750)、65.2%(489/750)、10.9%(82/750),调整是否独立睡眠、睡前是否接接触电子产品、是否定时睡觉起床、学习日运动时间、运动项目参与率等因素的相互影响后,学习日运动时间较少(OR=0.430,95%CI:0.205~0.904,P=0.026)、未参与散步(OR=0.399,95%CI:0.175~0.908,P=0.028)与学龄前儿童睡眠质量差成正向关联。结论学习日运动时间较少与学龄前儿童睡眠质量差的发生有关。

Objective To analyze the relationship between exercise and sleep quality of preschoolers,and to explore the early life factors affecting sleep quality of preschoolers. Methods A total of 833 preschoolers aged 3-6 years in 4 kindergartens registered in Shanghai were selected as participants from March to June 2018,and 750 valid samples were analyzed.Multivariate non-conditional Logistic regression model was used to analyze the relationship between exercise time,items and sleep quality of preschool children. Results The proportion of less time for exercise on school day and rest day for preschool children was 72.7%(545/750) and 27.2%(204/750),respectively.And the walking participation rate was 73.5%(551/750).Children with good,moderate and poor sleep quality accounted for 23.9%(179/750),65.2%(489/750) and 10.9%(82/750),respectively.After adjusting some interacting factors,it was found that less exercise time on study days(OR=0.430,95%CI:0.205-0.904,P=0.026) and non-participation in walking(OR=0.399,95% CI:0.175-0.908,P=0.028) were positively related to preschool children′s poor sleep quality. Conclusion Less exercise time on study day is associated with poor sleep quality in preschool children.
