Kourkoumelis et al reported an equation for fat-free mass (FFM) in a pediatric patient. The authors are from multiple institutions in Europe and Australia.
Analysis: deuterium dilution technique, bioelectrical impedance analysis (BIA)
Parameters:
(1) height in centimeters
(2) resistance in ohms at 50 kHz
(3) weight in kilograms
(4) sex (0 female, 1 male)
fat-free mass in kilograms =
= (0.59 * ((cm)^2) / (resistance)) + (0.16 * (weight)) * (0.71 * (points for sex)) + 1.4
