【目的】 研究母亲孕期增重及婴儿喂养方式对儿童肥胖的影响,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2个社区的4所二级幼儿园共计儿童949名。自行设计问卷调查儿童的身高、体重、家庭基本状况、母亲孕期、喂养早期状况等。使用χ²检验及多因素Logistic回归模型分析母亲孕期及喂养早期状况与儿童肥胖的关系。 【结果】 研究结果显示, 调查到的949名儿童中,超重及肥胖检出率分别为13.2%和10.1%; 在控制儿童年龄、性别、户口属性、家庭结构、家庭收入后,孕期增重≥15 kg、6月龄内纯母乳喂养2个因素与儿童肥胖有关。 【结论】 母亲孕期增重显著可能为儿童肥胖的危险因素;而6月龄内纯母乳喂养则可能减少儿童肥胖的发生,为保护性因素。

【Objective】 To study the association of mothers' weight gain during pregnancy and infants' early feeding mode on children' obesity so as to provide the clues for preventing the children's obesity. 【Methods】 A total of 949 children from four second-level kindergartens were selected randomly from two communities in Hongkou district in Shanghai. A self-designed questionnaire was used to investigate the children's weight, height, family conditions, the mothers'weight gain during pregnancy and infants' feeding mode,and so on. The relationship between the mothers' weihgt during the pregnancy, infants's feeding mode and children's obesity were analyzed with χ² test and binary logistic regression. 【Results】 Resulst of the study showed that the rates of obesity and over-weight was 10.1% and 13.2% respectively. Pregnancy weight gain ≥ 15 kg, children exclusively breastfed within 6 months were associated with obesity when age, gender, the characteristic of registered residence,family structure and family income were considered. 【Conclusions】 Mother's weight gain more than 15 kg during pregnancy may be a risk factor for childhood obesity; And exclusive breastfeeding within 6 months may be a protective factor on children's obesity which may reduce the incidence of obesity in children.
