Purpose: The purpose of this study is to compare the growth pattern of breast fed and formula fed infants in the first 1 year of life.
Methods: Anthropometric data(weight, length, head circumference) of at birth, 1, 3, 6, 9 and 12 months were collected by chart review and characteristics of subjects were collected by questionnaires. Among 358 infants, breast fed infants were 161(84 males, 77 females) and formula fed infants were 90(42 males, 48 females). Neither group was given solid foods before 4 months. The weight for age, length for age and head circumference for age were calculated. Breast fed infants were separated into 2 groups(breast fed for 4-11 months and breast fed for more than 12 months).
Results: Characteristics of infants and mothers were similar in both groups except for maternal age. Mean weight of breast fed group was lower than that of formula fed group at 12 months of age(male:P=0.004, female:P=0.004). However, mean weight of 12 months breast fed group was below formula fed groups weight at 9 and 12 months(P<0.05). Mean length and head circumference were similar between groups.
Conclusion: The growth indices of breast fed and formula fed infants are similar at birth, but weight curves of two groups differ in the first 1 year.
