【目的】 了解上海部分地区儿童肥胖流行现状, 研究人口学特征与儿童肥胖的关系,为制定预防儿童肥胖措施提供依据。 【方法】 利用整群抽样的方法,随机抽取上海市虹口区、普陀区、浦东新区3个区的10所幼儿园共计儿童1 320名。自行设计问卷调查儿童的身高、体重、生活习惯和父母的情况等。 被调查儿童的身高和体重数据来源于当年的“六一”体检资料, 使用χ²检验及多因素Logistic回归分析人口学特征与肥胖的关系。 【结果】 研究结果显示, 调查到的1 320名儿童中,肥胖及超重儿童分别占被调查人数的10.5%和14.0%;在不控制其他变量时,户籍、父母亲的体质指数(body mass index, BMI)、独生子女、家庭结构与儿童肥胖有关,在考虑其它变量的影响后,父亲BMI、母亲BMI、家庭结构3个因素与儿童肥胖有关。 【结论】 儿童肥胖和超重的检出率已接近发达国家,父母BMI高的和核心家庭是上海儿童肥胖的主要影响因素。

【Objective】 To examine the epidemic of children's obesity in some areas of Shanghai and the relationship between demographic characteristics and children's obesity so as to provide the clues for preventing the obesity. 【Methods】 1 350 children from ten kindergartens were selected randomly from Hongkou district, Putuo and Pudong in Shanghai. A self-designed questionnaire was used to investigate the children's weight, height, and parenting characteristics, and so on. Children's height and weight came from the data of physical check in June, 2009. The relationships between demographic characteristics and children's obesity were analyzed with χ² test and multivariable logistic regression. 【Results】 The data showed that the rates of obesity and over-weight were 10.5% and 14.0% respectively. The place of registered residence, father's BMI, mother's BMI, children from only child family, and family structure were associated with obesity when other variables were not controlled. The father's BMI, mother's BMI, and family structure were associated with obesity when other variables were considered. 【Conclusions】 The rate of obesity and overweight in Shanghai is similar to that in developed countries. The main influence factor of child obesity in Shanghai is highly parents' BMI and nuclear family.
