Age-dependent changes in body fat can often be observed in normal population. A series of indirect body fat estimates, such as hydrodensitometry, Bioelectrical Impedance Analysis(BIA), and anthropometry equation for body fat, have been developed. The BIA made it possible to analyze body fat mass more related to hydrodensitometry than anthropometry. This study is to compare the body composition analysis between bioelectrical impedance analysis(BIA) and anthropometric measurements of women. The subjects were a group of Daejeon residents including 32 young-aged women($21.50{\pm}1.44$), 30 middle-aged women($50.33{\pm}5.27$), and 40 old-aged women($69.22{\pm}5.74$). We used BIA(inbody 3.0, Biospace Korea) to determine body fat and other body composition. We also measured weight, height, circumference for 12 parts, and skinfold thickness for 9 parts of all subjects' body. The results are as follows: The subjects' height by the age group were $161.74{\pm}0.94cm$ in the young-aged women, $154.16{\pm}1.09cm$ in the middle-aged, and $148.60{\pm}0.78cm$ in the old-aged respectively. BMI were, in order, $21.68{\pm}0.49,\;22.87{\pm}0.89,\;and\;23.85{\pm}0.55$. Relative body fat determined by BIA was, also in order, $29.06{\pm}0.92%,\;26.35{\pm}1.02%,and\;29.35{\pm}1.07%$. Circumference and skinfold that showed the highest correlation with body fat by BIA was waist in the young-aged(r=0.738) and bast in the middle- and old-aged(r=0.844, r=0.804), and triceps in the young-and old-aged(r=0.538, r=0.798), and subcostal in the middle-aged(r=0.872). Body fat Estimations by BIA were the highest correlation with Caucasian women's equation(r=0.588) in young-aged women, Siri's equation with Durnin & Womesley's body density measurement(r=0.875) in middle aged women and Caucasian women' equation(r=0.872) in old aged women. We need to develop specific anthropometric equations based on sex and age to determine body fat.

Body fat proportion is a major issue in health. The prevalence of obesity in childhood has been increasing on thesedays. A series of indirect estimates of body fat have been developed. There are hydrodensitometry, BIA and anthropometry equation for body fat. Hydrodensitometry has been regarded as a common criterion method. BIA made it possible to analyze body fat mass more related to hydrodensitometry than anthropometry. The purpose of this unvestigation were to compare body fat and other body composition between boys & girls and to know which anthropometry equation for body fat was most closely associated with BIA in boys & girls respectively. The subjects were 148 4th grade elementary school students(male:70, female:78). They underwent BIA(InBody 3.0, Biospace Korea)to determine body fat and other body composition. Anthropometric measurements were taken of height, weight, skinfolds and circumferences. The results obtained are summarized as follow: 1) Weight, BMI and Rohrer index were $39.9{\pm}7.2kg$, $20.5{\pm}8.0$, $138.2{\pm}17.0$ for boys and $35.9{\pm}6.7kg$, $18.2{\pm}2.6$, $96.6{\pm}13.6$ for girls. 2) Total body fat and percent body fat determined by BIA were $10.3{\pm}4.3kg$, $25.4{\pm}6.6%$ for the boys group and $9.3{\pm}3.8kg$, $25.1{\pm}6.0%$ for girls. 3) Mean triceps skinfold thickness was $20.5{\pm}6.1mm$ in boys, $17.0{\pm}5.1mm$ in girls and mean WHR was $0.88{\pm}0.4$ in bodys, $0.82{\pm}0.4$ in female and the values were significantly different by sex. 4) Correlational nanlyses showed that estimation of body fat by BIA measurement seemed to be closely associated with Rohere index(boys r=0.854, girls r=0.909). Kim's equation was highly correlated with the body fat in girls(r=0.910) but less correlated in boys(r=0.710). We need to develop specific anthropometric equations based on age and sex to determine body fat for children.

목 적 : 소아 비만은 체중을 감소시키려는 노력에 불구하고도 계속적으로 증가하는 추세이며, 6세 이전에 나타나는 경우가 1/3 이상을 차지한다. 생체 전기 저항법(BIA)은 장치가 간단하고 특별한 기술을 필요로 하지 않으며, 측정치가 객관적이고 정확하다는 장점이 있다. 그러나 7세 미만의 소아에서 BIA를 이용한 체성분 분석에 대한 자료가 없는 실정이다. 이에 저자들은 7세 미만의 정상 아동을 대상으로, BIA를 이용하여 체성분과 체지방량, 체지방율을 비교 분석하였고, 비만의 판정이나 추적 관찰에 있어서 BIA의 유용성을 알아보기 위해 본 연구를 시행하였다. 방 법 : 3-6세 사이의 남자 688명, 여자 688명의 1,376명 소아를 대상으로 신장과 체중, 체질량지수(body mass index)를 구하였고, BIA를 이용하여 체성분 분석을 하였고, 체지방량, 체지방율과 신체 계측치와의 상과관계를 연구하였다. 결 과 : 체지방량, 체지방율, 세포내액, 세포외액, 단백질, 무기질이 비만군에서 정상군에 비해 유의하게 높았다. 체지방량과 체질량지수($R^2=0.69$, P <0.05), 체중($R^2=0.62$, P <0.05)과 상관성이 유의하게 높았다. 체지방율과 체질량지수($R^2=0.56$, P <0.05), 체중($R^2=0.19$, P <0.05)과도 상관성이 유의하게 높았다. 결 론 : BIA에 의한 체성분 분석은 소아 비만의 진단에 매우 유용한 진단 방법이라 생각된다. 그러나 아직 6세 이하의 어린 소아에서 국내 자료가 없으므로 광범위한 역학 조사가 필요하리라 생각한다.
