본 연구는 서울시와 경기도 성남시에 소매하고 있는 중·고등학교 남녀 총 1,237명을 대상으로 신체조성 발달경향 특성을 분석하는데 목적이 있다. 신체조성은 다주파수 생체전기분석기인 InBody 2.0을 이용하여 체수분량, 체지방량, 제지방량, 체지방율, 복부지방율, 체질량지수, 기초대사량, 단백질을 측정하였으며, 자료분석은 WINDOWS용 SPSS Version 10.0과 MINITAB 통계프로그램을 이용하여 독립 t-검증(independent t-test)과 경향분석(trend analysis)법으로 분석하여 다음과 각은 결론을 얻었다. 1. 신체조성 특성 중 체수분량, 제지방량, 복부지방율, 기초대사량, 단백질은 남학생이 유의하게 높게 나타났고 체지방량, 체지방율은 여학생이 유의하게 높게 나타났으나, 체질량지수는 유의한 차이가 없었다. 2. 여학생의 신체조성(체지방율, 체지방량, 제지방량, 기초대사량, 체질량지수, 총수분량, 복부지방을, 단백질)은 연령이 올라감에 따라 정적발달경향을 나타내고 있으며, 남학생은 체수분량, 제지방량, 체질량지수, 기초대사량, 단백질은 정적발달경향이 있는 것으로 나타났으며 체지방량, 체지방율, 복부지방율은 부적발달경향을 나타냈다.

The purpose of this study was to analyze body composition development trend of youth. The subjects were 1,237 male and female in middle/high schools located in Seoul city and Kyungkido. Body composition was measured by InBody 2.0 of a segmental multifrequency impedance analyzer. The measured items were total body water, fat mass, fat free mass, %body fat, waist hip ratio, body mass index, protein mass and basal metabolic rate. The data were analyzed with independent t- test, trend analysis using SPSS Version 10.0 and MINITAB. The results were as follows: 1. Body composition of male subjects was dramatically higher in total body water, fat free mass, waist hip ratio, body mass index and protein mass and that of female subjects was significantly higher in fat mass and %body fat, however, body mass index had no significant difference in female and male subjects. 2. Body composition(total body water, fat mass, fat free mass, %body fat, waist hip ratio, body mass index, protein mass and basal metabolic rate) of female subjects, it shown that positive development depending on their growth. Male subjects had positive development in total body water, fat free mass, body mass index, basal metabolic rate and protein mass but fat mass, %body fat, and waist hip ratio had negative development
