摘要
目的了解新冠肺炎疫情初期上海市学龄儿童网课相关电子屏幕使用时长和类型,为加强相关健康教育提供依据。方法采用随机整群抽样,于2020年4月抽取上海市嘉定区、浦东新区和宝山区国家近视调查学校库中的8所中小学5591名学生家长作为研究对象,采用电子问卷对家长开展疫情期间学生网课行为相关调查。结果学生个人每周网课相关电子屏幕使用总时长中位数为13.33 h,每周课程和课外网课相关电子屏幕使用时长分别为10(8.75,16.67)和0(0,3.33)h,29.44%的学生仅使用小屏幕设备上网课。高年级、近视学生以及父母均不近视学生网课相关电子屏幕使用时间更长(P值均<0.05);小学高年级以及父母均不近视学生仅使用小屏幕作为网课设备的概率更高(P值均<0.05)。结论新冠肺炎疫情初期,上海市学龄儿童网课相关电子屏幕使用负担过重,出现不良网课相关电子屏幕使用行为。应加强学龄儿童父母有关网课相关电子屏幕使用健康教育,正确引导儿童使用电子屏幕开展网课。
Objective To understand the online learning-related screen use duration and screen types in school-aged children in Shanghai during the COVID-19 epidemic.Methods Random clustering sampling was used to select 5591 parents of students from 8 primary and junior schools that are in the sampling pool of the national myopia survey in districts of Jiading,Pudong and Baoshan in Shanghai in April 2020.Electronic questionnaire was administered to parents regarding their child’s online learning-related screen use.Results On average,the median weekly duration of online learning-related screen use was 13.33 hours,the curricular and extracurricular parts of which were 10(8.75,16.67)and 0(0,3.33)hours,respectively.About 29.44%of investigated school-aged children only used small-size screen for online learning.Children in higher grades,being myopic and parents neither being myopic were associated with reporting higher weekly duration(P<0.05);children in higher grades of primary school and parents neither being myopic were associated with a higher likelihood of using small-size screen for online learning(P<0.05).Conclusion At the early stage of the COVID-19 epidemic,the burden associated with online-learning-related screen use was high in school-aged children in Shanghai.Health education regarding online learning-related screen use should be addressed in parents to guide their children to use screen appropriately.
