Kim, H.S., Lee, K.J. Predictive accuracy of bioelectrical impedance and anthropometry methods in estimating body composition in elderly. Exercise Science, 14(3): 241-250, 2005. Bioimpedance (BI) and anthropometry (ANT) methods for assessing body composition have been used. The purpose of this investigation was to compare estimates of human body composition determined from foot-pad style BI and ANT methods. The human body composition was assessed by dual energy X-ray absorptiometry (DXA), BI method and ANT equation (svendsen, 1993). Twenty three men and 24 women, aged 60-82 years, served as subjects. The mean (SD) percentage of body fat (%BF) assessed by DXA, BI, and ANT methods were 28.4 (8.6)%, 28.1 (8.2)% and 25.7 (8.1)%, respectively. There were high validity coefficients (r=.91 and .95, for BI and ANT, respectively) with the %BF measured by DXA. However, compared to the criterion measures of %BF (DXA), the magnitude of agreement in the BI and ANT revealed a different pattern. The mean absolute difference between DXA and BI measurements was -0.5 (2.8) %BF and, between DXA and ANT it was 1.6 (2.5) %BF. Compared to the DXA method, the STF method was as much as a 9.5% underestimation of %BF. The results suggest that although the ANT provided high correlation with criterion value, use of the ANT may not suitable for assessing the %BF of the elderly in Korea. |
