목적: 본 연구는 학동전기 어린이에서 과체중과 비만을 찾기 위한 체지방률 백분위수를 규정하기 위해 설계되었다.
방법: 3~6세 어린이 1301명의 키와 몸무게를 측정하였다. 또한 생체전기저항 분석법(BIA)로 체지방률을 측정하였다.
결과: 남아에서 체지방률 85백분위수는 22.3%(3세), 23.4%(3.5세), 23.9%(4세), 24.8%(4.5세), 22.8%(5세), 24.6%(5.5세), 23.8%(6세)였고 체지방률 95백분위수는 24.9%(3세), 27.5%(3.5세), 27.3%(4세), 28.6%(4.5세), 28.1%(5세), 33.3%(5.5세), 32.7%(6세)였다. 여아에서 체지방률 85백분위수는 23.3%(3세), 24.4%(3.5세), 23.6%(4세), 23.7%(4.5세), 24.7%(5세), 26.0%(5.5세), 28.1%(6세)였고 체지방률 95백분위수는 28.6%(3세), 27.3%(3.5세), 25.4%(4세), 28.0%(4.5세), 31.7%(5세), 33.5%(5.5세), 36.4%(6세)였다.
결론: 체지방률 85분위수로 분류한 과체중군, 체지방률 95분위수로 분류한 비만군과 2007년 한국 소아과학회에서 제시한 체질량지수(BMI)의 분류에 의해서 나눈 과체중군, 비만군은 중등도의 일치도를 보였다.
Objectives: This study was designed to regulate the percentile of body fat percentage by Bioelectrical Impedence Analysis (BIA) in order to detect overweight and obesity in preschool children.
Methods: 1301 three to six year old children’s height, weight, and body fat percentage using BIA was measured.
Results: The percent of the boys with 85th percentiles of the body fat percentage were 22.3%(3years), 23.4%(3.5years), 23.9%(4years), 24.8%(4.5years), 22.8%(5years), 24.6%(5.5years) and 23.8%(6years). The percent of the girls with 95th percentiles of the body fat percentage were 24.9%(3years), 27.5%(3.5years), 27.3%(4years), 28.6%(4.5years), 28.1%(5years), 33.3%(5.5years) and 32.7%(6years).
For the girls, the percent of girls with 85th percentiles of body fat percentage were 23.3%(3years), 24.4%(3.5years), 23.6%(4years), 23.7%(4.5years), 24.7%(5years), 26.0%(5.5years) and 28.1%(6years). And the 95th percentiles of the body fat percentage were 28.6%(3years), 27.3%(3.5years), 25.4%(4years), 28.0%(4.5years), 31.7%(5years), 33.5%(5.5years) and 36.4%(6years).
Conclusions: The 85th percentiles of body fat percentage to classify as overweight and the 95th percentiles of body fat percentage to classify as obesity were accord with the Body Mass Index (BMI) criteria by the Korean pediatrics society in 2007.
