A total of 61 male and 64 female subjects aged over 60 years were recruited from middle Taiwan. The R and Xc were measured using Bodystat Quadscan 4000 at a frequency of 50 kHz. BMD at the whole body, L2–L4 spine, and dual femur neck (DFN), denoted as BMDTotal, BMDL2–L4, and BMDDFN, were calculated using a Hologic DXA scanner. The R-Xc graph was used to assess vector shift among diferent levels of BMD. BMD was positively correlated with Xc/H and negatively correlated with R/H (p< 0.001). The General Linear Model (GLM) regression results were as follows: BMDTotal = 1.473–0.002 R/H+ 0.007 Xc/H, r = 0.684; BMDL2–L4 = 1.526–0.002 R/H+ 0.012 Xc/H, r = 0.655; BMDDFN = 1.304–0.002 R/H+Xc/H, r = 0.680; p < 0.0001. Distribution of vector in the R-Xc graph was signifcantly diferent for diferent levels of BMDTotal, BMDL2–L4 and BMDDFN. R/H and Xc/H were correlated with BMD in the elderly. The linear combination of R/H and Xc/H can efectively predict the BMD of the whole body, spine and proximal femur, indicating that BIVA may be used in clinical and home-use monitoring tool for screening BMD in the elderly in the future.1317587 bytesapplication/pdfarticle
