【摘要】：目的分析广州市城区学龄儿童家庭电子产品拥有情况及视屏时间与体质量指数(body mass index,BMI)的关系,为减少儿童久坐行为的家庭策略提供科学依据。方法采用多阶段分层随机整群抽样方法,抽取广州市5个城区29所小学的9 260名一~五年级小学生进行体格检查,对学生家长进行问卷调查。分析小学生家庭电子产品拥有率及平均每天视屏时间,采用Spearman相关分析家庭电子产品拥有率与儿童视屏时间、BMI的关系。结果广州市7~12岁儿童超重肥胖率为18.84%,家庭电视、影像/DVD播放机、无网络计算机、连接网络计算机的拥有率分别为96.22%,69.21%,33.01%,76.19%,公办学校学生家庭4类电子产品拥有率均高于民办学校学生家庭(χ2值分别为174.280,312.444,53.918,644.181,P值均0.01)。儿童每天看电视、录像和DVD时间中位数为1.60 h,玩计算机游戏时间为0.50 h。民办学校儿童看电视等及玩计算机游戏的时间均高于公办学校儿童(Z值分别为14.802,6.852,P值均0.01);男生每天看电视等及玩计算机游戏的时间均高于女生(Z值分别为-2.020,-6.782,P值均0.05);超重/肥胖组儿童每天玩计算机游戏时间高于非超重肥胖组儿童,差异有统计学意义(Z=3.074,P=0.002)。家庭拥有计算机(连接网络)的儿童BMI-Z评分高于家庭无计算机(连接网络)的儿童(Z=3.240,P=0.001)。随着每天玩计算机游戏时间的增加,儿童BMI-Z评分升高(r=-0.048,P=0.002)。结论儿童BMI与家庭是否拥有连接网络的计算机及每天玩计算机游戏时间有相关性。不同类型学校儿童及不同性别儿童电子产品使用时间有差异,在进行儿童健康生活方式干预工作时,应考虑到性别及学校类型特点。
[Abstract]:Objective to analyze the relationship between family electronic product ownership, video time and body mass index (mass) of school-aged children in Guangzhou, so as to provide scientific basis for reducing children's sedentary behavior. Methods the method of multi-stage stratified random cluster sampling was used to select 9 260 primary school students from 29 primary schools in 5 urban areas of Guangzhou for physical examination, and a questionnaire survey was carried out to the parents of the students. The Spearman correlation was used to analyze the relationship between home electronic product ownership and children's video time. Results the overweight and obesity rate of children aged 7 to 12 in Guangzhou was 18.84. Home TV, video / DVD player, no network computer, The ownership rate of computer connected to network was 96.22 / 69.21 / 33.01 and 76.19, respectively. The ownership rate of electronic products in public school students' families was higher than that in private school students' families (蠂 ~ 2 = 174.280312.444 / 53.918644.181, P = 0.01respectively). The median time of watching TV, video and DVD was 1.60 h and playing computer games was 0.50 h. The time of watching TV and playing computer games in private schools was higher than that of children in public schools (14.802 / 6.852, P = 0.01), and the time of watching TV and playing computer games in boys was higher than that of girls (-2.020 / -6.782P, 0.05, respectively). Children in the overweight / obese group played computer games more often than those in the non-overweight group. The difference was statistically significant. The BMI-Z score of children with a home computer (connected network) was higher than that of children without a computer (connected network). With the increase of the time of playing computer games every day, the BMI-Z score of children increased r-0.048 P0. 002. Conclusion there is a correlation between children's BMI and whether their family has a computer connected to the network and how long they play computer games every day. There are differences in the time of use of electronic products among different types of school children and children of different genders. The characteristics of gender and school types should be taken into account in the intervention of children's healthy lifestyle.
