Association between breastfeeding and types of obesity in children and adolescents

Abstract

Objective To explore the association between breastfeeding and the type of obesity in children and adolescents, and to provide a theoretical basis for the identification and intervention of influential factors of different types of childhood obesity. Methods Using stratified cluster sampling method, 93 primary and secondary schools in 7 provinces and cities in China were selected for physical examination and questionnaire surveys. Totally, 30 437 primary and middle school students aged 7-17, with completed information, were selected. A multivariable Logistic regression model was used to analyze the association between breastfeeding and different types of obesity. Results The breastfeeding rate of students was 69.8%. The rates of general obesity, simple abdominal obesity, and combined obesity in the breastfeeding group were 7.1%, 3.9%, and 18.7%, the non-breastfeeding group were 7.0%, 4.7%, and 19.5%. The differences were statistically significant (χ 2 = 14.04, P <0.01). Univariate analysis found that breastfeeding significantly reduced the risk of simple abdominal obesity in children and adolescents ( OR = 0.81, 95% CI = 0.72-0.92, P <0.01) with normal (BMI non-overweight and obesity and waist

母乳喂养与儿童和青少年肥胖类型之间的关系

目的探讨母乳喂养与儿童青少年肥胖类型的关系，为识别和干预不同类型儿童肥胖的影响因素提供理论依据。方法采用分层整群抽样的方法，选取全国7个省市的93所中小学进行体检和问卷调查。共选取7-17岁的中小学生30 437人，资料完整。采用多变量Logistic回归模型分析母乳喂养与不同类型肥胖之间的关系。结果学生母乳喂养率为69.8%。母乳喂养组一般肥胖、单纯性腹部肥胖和合并肥胖的发生率分别为7.1%、3.9%和18.7%，非母乳喂养组分别为7.0%、4.7%和19.5%。差异有统计学意义(χ 2 = 14.04, P <0.01)。单因素分析发现，母乳喂养显著降低儿童和青少年单纯性腹部肥胖的风险(OR = 0.81, 95% CI = 0.72-0.92, P <0.01)，对照组为正常(BMI非超重、肥胖和腰围
