摘要

This research used bioelectricial-impedance analysis (BIA) to measure Taiwan young females'(average age 19.5±2.1) body fatness. By comparing three body fatness measurement equations (Womesley equation, Garrow equation and Black equation) using height, weight, age, sex and BMI as variables, the reasult indicated singnificant error from 5% to 55% in three equations. Although using Black equation produced high correlation with actual measurment (r=0.874, p＜0.0001), it showed significant error of 5%±18%. As a result, these three body fatness measurement equations can not properly caculate Taiwan young females' body fatness. Thus, the purpose of this study was to develop a suitable equation to develop a suitable equation to estimate Taiwan young females' body fatness. Bt using Regression Analysis comparing actual measurement and body mass index, this adapted formala is: BF% = 1.657 BMI -11.309 (error = 2 ± 18%).
Except above finding, the authors find that Taiwan young females' body mass index average is 21.0±2.8 kg/m^2 and body fatness average is 23.5±5.5%. From this finding, Taiwan young females' body mass index is fall within normal range (20-25 kg/rn^2). However, their body fatness is higher than normal range 14-18%) which shows fat tendency of Taiwan young females.
