Equation of Ben Jemaa et al for Estimating Fat-Free Mass in a Child Based on Impedance and Body Measurements

Description

Ben Jemaa et al developed an equation for estimating fat-free mass of a child based on impedance and body measurements. The authors are from the University of Tunis El Manar, National Institute of Nutrition and Food Technology of Tunis, Institute of Public Health in Tunis and CNESTEN-Ibn Tofail University Morocco.

Patient: child 8 to 11 years old

Parameters =

(1) height in cm

(2) resistance in ohms

(3) age in years

(4) weight in kilograms

(5) gender (0 if female, 1 if male)

resistance index =

= (((height)^2)/(resistance))

fat-free mass in kg =

= (0.110 * (((height)^2)/(resistance)) + (0.451 * (age in years)) + (1.097 * (points for gender)) + (0.403 * (weight)) + 2.188
