This single-center cross-sectional trial involved comparing the FM of 60 HD patients estimated BHD and AHD by BIA (multifrequential; 29 women, 31 men) and by SKF with those estimated by the reference method, ADP. Body fat-free mass (FFM) was also obtained by subtracting the total body fat from the individual total weight.
Mean estimated FM (kg [ % ]) observed by ADP BHD was 17.95 ¡À 0.99 kg (30.11 % ¡À 1.30 % ), with a 95 % confidence interval (CI) of 16.00 to 19.90 (27.56 to 32.66); mean estimated FM observed AHD was 17.92 ¡À 1.11 kg (30.04 % ¡À 1.40 % ), with a 95 % CI of 15.74 to 20.10 (27.28 to 32.79). Neither study period showed a difference in FM and FFM (for both kg and % ) estimates by the SKF method when compared with ADP; however, the BIA underestimated the FM and overestimated the FFM (for both kg and % ) when compared with ADP.
The SKF, but not the BIA, method showed results similar to ADP and can be considered adequate for FM evaluation in HD patients.
