요약1 The bioelectrical impedance analysis (BIA) has been proposed as a convenient, valid approach to estimate body composition in normal, healthy people. BIA prediction equations are based on either population-specific or generalized models. The aims of this study were to develop a convenient, useful equation that would sufficiently predict fat free mass (FFM) and to determine the validity of predict equation in Korean women. The participants were 220 Korean women aged 18~59 years (height 159.2±5.2 cm, body weight 58.5±7.3 kg; means±sd). FFM based on underwater weighing (UW) was used as the criterion for validity. To construct prediction equations for FFM, we used multiple regression analysis, whereby all possible combinations were examined. The linear multiple regression equation constructed for predicting the FFM was, for instance, FFM = 22.444 + 0.00444*(BW H2/R) - 0.0944*age - 0.257*T, where, BW = body weight (kg), H: body height (cm), R = impedance (ohms), T = triceps skinfold thickness (mm). Four equations developed in the present study were then cross-validated in different sample (n = 27) of women. The results indicate that the above equation had the lowest SEE (2.38 kg). The FFM calculated using the new equations did not differ from that based on the UW method. In conclusion, the prediction equations in this study afford accurate and inexpensive means of estimating FFM in Korean adult women without having them remove their clothing.
