【摘要】 目的探讨疫情期间居家限制对学龄前儿童活动行为的影响,为特殊时期指导儿童健康生活提供依据。方法采用整群随机法抽取2020年3月9—12日广州市内7家幼儿园受居家限制的学龄前儿童1 453人作为调查对象,采用自制调查问卷调查其平时及疫情期间睡眠状况、运动状况、静坐行为等活动行为。同时,将调查对象按性别、年龄、是否独生子女、主要照护人及其文化程度进行分组,比较各组活动行为指标变化幅度。结果本次共发放问卷1 453份,回收有效问卷1 449份,有效问卷回收率为99.72%。平时入睡时间、起床时间、睡眠时间、每天运动时间、每周运动时间、每天总静坐时间、非屏幕静坐时间及屏幕静坐时间与疫情期间比较,差异有统计学意义(P<0.05)。不同文化程度照护组儿童疫情期间起床时间、每天运动时间、每天静坐时间变化幅度比较,差异均有统计学意义(P<0.05);而入睡时间、夜间睡眠时间、每周运动时间变化幅度比较,差异均无统计学意义(P>0.05)。其余各组活动行为指标变化幅度比较,差异均无统计学意义(P>0.05)。结论疫情期间,受居家限制的学龄前儿童的睡眠、运动、静坐行为较平时都发生了变化,主要照护人文化程度可能影响儿童疫情期间起床时间、运动时间、静坐行为,因此应重视学龄前儿童活动行为的管理。更多还原
