Description

Clasey et al used bioelectic impedance analysis (BIA) to estimate fat-free mass (FFM) in children. This can help to identify a child who may benefit from interventions to reduce body fat. The authors are from the University of Kentucky and University of Toledo.


 

Patient selection: healthy child, white non-Hispanic, 5 to 11 years of age

 

BIA: tetra-polar device (Bodystat 1500), using the average of 2 consecutive readings

 

Parameters:

(1) weight (body mass) in kilograms

(2) standing height in cm

(3) impedance in ohms

(4) age in years

 

predicted fat-free mass in kg =

= ((297 * (height)) + (125 * (weight)) - (17.4 * (impedance)) - 7655) / 1000 =

= (0.297 * (height)) + (0.125 * (weight)) - (0.0174 * (impedance)) - 7.655

 

Performance:

• R-squared vs DEXA FFM was 0.952.
