【目的】 基于5-2-1-0模式研究儿童超重、肥胖影响因素,为制定预防儿童肥胖措施提供依据。【方法】 利用分层随机整群抽样的方法,在山东省济南市、淄博市和临沂市抽取3所小学共计1 584名学龄儿童。自行设计调查问卷调查儿童身高、体重以及儿童的日常活动和饮食习惯情况等。采用χ²检验和多因素Logistic回归分析5-2-1-0模式与儿童超重、肥胖的关系。【结果】 研究结果显示,1 584名学龄儿童超重、肥胖检出率分别为13.8%和13.3%;5-2-1-0模式中日均看电视玩电脑时间、日均户外运动时间、一周喝甜饮料频率与儿童超重、肥胖有关。【结论】 我国城市儿童肥胖问题已接近发达国家水平;可以借鉴5-2-1-0模式中有意义的因素,提出一套预防我国儿童肥胖的健康促进模式。

【Objectives】 To study influencing factors of childhood overweight and obesity based on 5-2-1-0 model and to provide the basis for preventing childhood obesity. 【Methods】 Using stratified random cluster sampling method,a total of 1 584 school-age children were selected from three primary schools in Shandong Province.A self-designed questionnaire was used to survey children's height,weight,daily activities,eating habits and so on.The relationship between 5-2-1-0 model and childhood obesity was analyzed with χ² test and binary logistic regression. 【Results】 The research showed that the rates of the overweight and obesity were 13.8% and 13.3%,respectively.Daily TV watching and computer playing time,daily outdoor exercise time and weekly sugary drinks drinking frequency in 5-2-1-0 model were associated with childhood overweight and obesity. 【Conclusions】 The rates of urban childhood overweight and obesity in China are close to that in developed countries;Meaningful factors can be learned from 5-2-1-0 model and put forward a suitable health promotion model to prevent childhood overweight and obesity in China.
