Abstract

Participants (42% women, 52% with diabetes, 40% African Americans, and 38% Hispanics) were aged 49.4 ± 11.5 (mean ± SD) years, and had undergone dialysis therapy for 41.1 ± 32.9 months. Body mass index was 27.0 ± 6.0 kg/m2. Using DEXA as the reference test, the bioelectrical impedance analysis–Kushner equation, triceps skinfold, and near-infrared interactance were most accurate of the index tests in estimating total-body fat percentage, whereas bioelectrical impedance analysis–Segal equation and bioelectrical impedance analysis–Lukaski equation overestimated total body fat percentage. Bland-Altman analyses and difference plots showed that bioelectrical impedance analysis–Kushner and near-infrared interactance were most similar to the reference test. Bioelectrical impedance analysis–Kushner, triceps skinfold, and near-infrared interactance had the smallest mean differences from DEXA, especially in women (1.6%, 0.7%, and 1.2%, respectively). Similar results were observed in African American participants (n = 47).
