Abstract

Objective: To compare measurements of percentage body fat obtained using bioelectrical impedance and near infra-red interactance assessments to those obtained using dual energy x-ray absorptiometry, a reference technique. Design: Cross-sectional, cross-validation study. Percentage body fat was assessed using bioelectrical impedance analysis (Bodystat 1500, Tanita TBF-622 foot-to-foot analysers with proprietary equations and the equation of Kotler and colleagues) and near infra-red interactance (Futrex 1000). Results were compared with a Norland XR-26 dual energy x-ray absorptiometry scanner.
