초록

목 적 : 영아시기의 모유수유가 이후 소아기의 과체중이나 비만의 유병률에 영향을 줄 수 있는지를 알아보고자 하였다. 방 법 : 2004년도 마산 및 창원에 있는 4개의 초등학교 1학년과 2학년 1,275명을 대상으로 하여, 생활기록부로부터 키와 몸무게에 대한 정보를 바탕으로 BMI와 비만도를 구하였고 학부모를 대상으로 설문지를 보낸 후 수집하였다. 설문의 내용은 출생력(재태주수, 출생시 몸무게, 분만방식), 수유의 방법(모유 단독 수유, 분유 단독 수유, 혼합 수유, 모유수유 후 분유로의 전환) 및 그 기간에 대해서 표시하도록 하였다. 결 과 : 1) 과거 수유방식은 모유를 2개월 미만으로 먹고 이후 분유만 먹인 경우가 54.5%로 가장 많았고 모유를 2개월에서 6개월간 먹고 이후 분유 수유한 경우가 12.9% 7개월 이상 모유만 먹인 경우가 18.4%, 모유와 분유를 혼합해 먹인 경우가 14.3%였다. 2) BMI를 기준으로 과체중은 10.3%, 비만은 9.8%로 과체중 이상의 어린이는 전체 조사대상의 어린이 중 20.1%로 나타났다. 비만도를 기준으로 한 경우 경도 비만은 4.5%, 중등도 비만은 2.4%였고 고도비만은 없었다. 3) 수유방식에 따른 BMI를 적용한 과체중 및 비만의 유병률에 차이가 없었으며 이는 비만도를 적용한 경우에도 마찬가지였다. 4) 평균 체질량지수와 평균 비만도 역시 수유방식에 따른 차이가 없었다. 결 론 : 영아기 수유방식은 초기 학동기 어린이의 비만에 특이한 영향을 주지 않는 것으로 보아 모유의 비만예방에 대한 효과를 확인할 수 없었다. 그러나 어린이의 비만에 영향을 줄 수 있는 요인은 아주 많아 이를 고려하고 대상을 보다 광역화, 대량화한 연구가 추가적으로 진행되어야 할 것으로 사료된다.

Purpose : The aim of this study was to evaluate whether breast milk feeding at infancy has the effect of a programming agent preventing school-age obesity, or whether formula milk feeding is the cause of elementary school-age obesity. Methods : We randomly selected 4 elementary school in Masan and Changwon city. We calculated the BMI and obesity degree from height and weight data on the school record of 1,275 children of first and second grade. The parents of 1,275 children were asked to a questionnaire about their birth history and feeding modality during infancy. Based on these data, we categorized them into 4- different groups : breast fed for less than 2 months; breast fed for 2-6 months; breast fed more than 6 months; mixed fed. We compared the mean BMI, obesity degree and prevalence rates of obesity of each groups. Results : There was no statistical difference on the prevalence rates of overweight and obesity, which was defined by BMI, according to the duration of breast feeding. The same was true for mild obesity and moderate obesity, which was defined by obesity degree. The mean BMIs and the mean obesity degree were not different among different feeding types. Conclusion : There seems to be no protective effect of breast feeding during infancy on reducing the prevalence rates of overweight and obesity. However, even wider and larger studies considering confounding factor might be needed to reach a definite conclusion in the future.
