【摘要】：目的分析廣州市城區(qū)學齡兒童家庭電子產(chǎn)品擁有情況及視屏時間與體質(zhì)量指數(shù)(body mass index,BMI)的關系,為減少兒童久坐行為的家庭策略提供科學依據(jù)。方法采用多階段分層隨機整群抽樣方法,抽取廣州市5個城區(qū)29所小學的9 260名一~五年級小學生進行體格檢查,對學生家長進行問卷調(diào)查。分析小學生家庭電子產(chǎn)品擁有率及平均每天視屏時間,采用Spearman相關分析家庭電子產(chǎn)品擁有率與兒童視屏時間、BMI的關系。結果廣州市7~12歲兒童超重肥胖率為18.84%,家庭電視、影像/DVD播放機、無網(wǎng)絡計算機、連接網(wǎng)絡計算機的擁有率分別為96.22%,69.21%,33.01%,76.19%,公辦學校學生家庭4類電子產(chǎn)品擁有率均高于民辦學校學生家庭(χ2值分別為174.280,312.444,53.918,644.181,P值均0.01)。兒童每天看電視、錄像和DVD時間中位數(shù)為1.60 h,玩計算機游戲時間為0.50 h。民辦學校兒童看電視等及玩計算機游戲的時間均高于公辦學校兒童(Z值分別為14.802,6.852,P值均0.01);男生每天看電視等及玩計算機游戲的時間均高于女生(Z值分別為-2.020,-6.782,P值均0.05);超重/肥胖組兒童每天玩計算機游戲時間高于非超重肥胖組兒童,差異有統(tǒng)計學意義(Z=3.074,P=0.002)。家庭擁有計算機(連接網(wǎng)絡)的兒童BMI-Z評分高于家庭無計算機(連接網(wǎng)絡)的兒童(Z=3.240,P=0.001)。隨著每天玩計算機游戲時間的增加,兒童BMI-Z評分升高(r=-0.048,P=0.002)。結論兒童BMI與家庭是否擁有連接網(wǎng)絡的計算機及每天玩計算機游戲時間有相關性。不同類型學校兒童及不同性別兒童電子產(chǎn)品使用時間有差異,在進行兒童健康生活方式干預工作時,應考慮到性別及學校類型特點。
[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.
