According to the feeding types before 4 months old, they were classified into breast feeding group and bottle feeding group. The prevalence of overweight and obesity in different months were compared between the two groups. 【Results】 The prevalence of obesity and overweight in bottle feeding group were elevated with age increased and reached peak in 12 months old, then decreased gradually, while they were gradually declined with age increased in breast feeding group. In 18 months old, obesity was more prevalent in the infants with bottle feeding than that with breast feeding(P<0.05). In 12 and 24 months old, the rates of overweight and obesity were significantly higher in bottle feeding group than that with breast feeding(P<0.05). Furthermore, in both groups, the prevalence of obesity and overweight were both declined with age increased in 3 months old obesity and overweight children, especially in breast feeding group(P<0.05). 【Conclusion】 Early breast feeding may have a potential benefit in preventing the occurrence and aggravation of infant obesity and overweight within 2 yeas old. %U https://manu41.magtech.com.cn/Jwk_zgetbjzz/EN/abstract/article_1088.shtml
