Body composition in 18‐ to 88‐year‐old adults—comparison of multifrequency bioimpedance and dual‐energy X‐ray absorptiometry

Abstract

Compared to DXA, BIA provided systematically different body composition estimates throughout the adult age span with considerable amount of intraindividual variation. The differences between estimates may be related to the BIAs' algorithm or body geometry or composition of the population used in this study. Knowledge about the methodological limitations and device comparability is essential for researchers, clinicians, and persons working in rehabilitation and sport centers.
