Overweight children are more prone to become overweight or obese adults. The most effective prevention is intervention in early childhood. We analyzed the association between early weight gain and overweight/obesity in 1,056 children under 11 years of age. Data were collected on lifestyle, sanitation, socioeconomic status, birth weight, and breastfeeding. Weight gain from birth until different age brackets (< 12, > 12 to 18, > 18 to 24, and > 24 to 60 months) was considered a continuous variable in z-scores. Overweight was defined as body mass index (BMI) > +1 z-score, based on 2006 and 2007 World Health Organization (WHO) guidelines. Poisson regression and linear regression were used in the multivariate statistical analysis. Weight gain rate was associated with BMI, and overweight or obesity in the 5-11-year age bracket increased twofold for each unit increase in the weight gain standard deviation between 24 and 60 months of age (RR = 2.08; 95%CI: 1.87-2.32). For all early childhood age brackets, there was an association between rapid weight gain and subsequent overweight or obesity.
超重儿童更易成为超重或肥胖的成年人。最有效的预防措施是在儿童早期进行干预。我们分析了1056名11岁以下儿童早期体重增加与超重/肥胖之间的关联。收集了生活方式、卫生条件、社会经济地位、出生体重和母乳喂养等方面的数据。从出生到不同年龄段（<12个月、>12至18个月、>18至24个月以及>24至60个月）的体重增加被视为z分数中的连续变量。根据2006年和2007年世界卫生组织（WHO）的指南，超重被定义为体重指数（BMI）>+1 z分数。多变量统计分析采用泊松回归和线性回归。体重增加率与BMI相关，在5至11岁年龄组中，24至60个月龄之间体重增加标准差每增加一个单位，超重或肥胖的风险就增加两倍（相对风险=2.08；95%置信区间：1.87-2.32）。对于所有儿童早期年龄段，快速体重增加与随后的超重或肥胖之间均存在关联。
