【目的】调查研究国内体检儿童少年的电子媒体使用状况。【方法】采用整群抽样的方法,自行设计问卷,对在温州医学院附属育英儿童医院进行体检的6～16岁儿童少年及其家长,共305例进行电子媒体使用情况回顾性访问及家庭环境调查。【结果】46.23%(141/305)的儿童少年平均每天使用电子媒体工具时间超过2h;各年龄组在每周使用电子媒体工具时间(Time/week,以下简称T/w,以h为单位)上差异无统计学意义(F=1.294,P=0.272);T/w与家长有无限制、家庭中有无早晨开电视习惯、有无以媒体工具打发时间的习惯差异有高度统计学意义(t=-4.848、-2.814、-6.174,P均<0.01);睡前看电视不会影响睡眠的儿童与有此影响的儿童相比,T/w更容易超过14h(χ2=4.424,P=0.038)。【结论】温州市儿童少年有大量时间在使用电子媒体工具,家庭中儿童看电视的习惯、爱好至少在儿童6岁左右已经基本形成;家庭在对儿童电子媒体使用中的影响起重要作用;看电视对儿童睡眠的影响不在于看电视的总和时间。
【Objective】 To investigate the use of electronic media in children’s physical examination in China. 【Methods】 A cluster sampling method was used to design a questionnaire. A total of 305 children and adolescents aged 6-16 years who were physically examined at Yuying Children’s Hospital of Wenzhou Medical College were enrolled. A total of 305 children were interviewed for retrospective electronic home use and family environment survey. 【Results】 46.23% (141/305) of children and adolescents spent more than 2 hours per day on average using electronic media tools. Each age group used weekly electronic media tools (Time / week, referred to as T / w, in h) (F = 1.294, P = 0.272); There was no difference between T / w and parents, whether the family had TV habits in the morning or not, and there was a significant difference in the habits of using media tools to pass the time t = -4.848, -2.814, -6.174, P <0.01). T / w was more likely to exceed 14h in children who did not affect sleep before bedtime (χ2 = 4.424, P = 0.038). 【Conclusion】 Children and adolescents in Wenzhou have a lot of time using electronic media tools. The habits and preferences of children watching TV in their families have basically taken shape at least around 6 years old. The family plays an important role in the children’s use of electronic media. The impact of television on children’s sleep does not lie in the total time it takes to watch television.
