Noori et al reported equations for estimating lean body mass for a patient receiving maintenance hemodialysis. The authors are from Harbor-UCLA Medical Center, Salem Veterans Affairs Medical Center, University of Alberta and UCLA.
Patient selection: maintenance hemodialysis
Parameters:
(1) serum creatinine in mg/dL
(2) sex
(3) weight in kilograms
(4) height in inches
(5) urea reduction ratio (URR)
(6) handgrip strength of dominant hand (type of dynamometer and units not stated; most studies use kilograms but the equation below requires low values)
(7) mid-arm muscle circumference in cm (MAMC, mid-arm circumference minus term for triceps skinfold thickness)
LBM in kg using creatinine and URR =
= (0.34 * (creatinine)) + (5.58 if female, else 0) + (0.30 * (weight)) + (0.67 * (height)) - (0.23 * (URR)) - 5.75
LBM in kg using handgrip strength =
= (9.09 * (handgrip)) + (5.15 if female, else 0) + (0.33 * (weight)) + (0.74 * (height)) - 29.06
LBM in kg using MAMC =
= (0.28 * (MAMC)) + (5.52 if female, else 0) + (0.28 * (weight)) + (0.82 * (height)) - 35.3
