Authors' objectives:

This aim of this report was to assess whether in patients with chronic obstructive airways disease (COPD), bioelectric impedance analysis (BIA) is a valid measure of fat free mass (FFM).

Authors' recommendations: The study appraised was appropriate to answer the question posed. In this study, compared to DEXA, BIA had a sensitivity of 86% and a specificity of 88% in detecting nutritional depletion (defined as FFMI2 <=15 for females or <=16 for males). These values imply BIA will detect 86% of patients who are nutritionally depleted, and correctly identify 88% of those patients who are not nutritionally depleted. There were significant differences between BIA and skin fold arthropometry (SFA). Further, there were differences in the accuracy of both tests between sexes. Insufficient information was provided to enable calculation of sensitivity and specificity for men and women separately.
