Abstract

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.

목 적 : 모유수유아와 분유수유아의 생후 첫 일년간의 성장 패턴을 비교하기 위함이다. 방 법 : 의무 기록지를 통해 출생시, 1, 3, 6, 9 그리고 12개월의 신체 계측치(체중, 신장, 두위)가 수집되었고, 설문 조사를 통해 대상의 특징들이 모아졌다. 358명의 소아들 중 모유수유아는 161명(남아 84명, 여아 77명)이었고, 분유수유아는 90명(남아 42명, 여아 48명)이었다. 두 군 모두에서 4개월 이전에는 이유식을 공급하지 않았다. 각 연령별 체중, 신장, 두위가 계산되었다. 모유수유군은 다시 두 군(4-11개월간 모유수유를 한 군과 12개월 이상 모유수유를 한 군)으로 세분되었다. 결 과 : 엄마의 연령을 제외하면 대상의 특징들은 두 군에서 유사하였다. 모유수유군의 평균 체중은 12개월에만 분유수유군 보다 낮게 측정되었다(male : P=0.004, female : P=0.004). 하지만, 12개월 이상 모유수유만 한 군의 평균 체중은 9개월과 12개월에 분유수유군 보다 낮았다(P<0.05). 평균 신장과 두위는 두 군에서 유사하였다. 결 론 : 모유수유아와 분유수유아의 성장 지표들은 출생시에는 유사하나 생후 첫 일년간 두 군의 체중 곡선이 다르게 나타난다.
