How do you calculate lean body mass in children using Peter Formula?
Lean body mass in children is the amount of weight carried by the children on their body which is not fat. The lean body mass (LBM) in children is calculated to prescribe certain drug dosage. LBM in children is estimated from the height and weight using the Peter Formula. This is a short tutorial that explains you on how to calculate the lean body mass (LBM) in children using the Peter Formula.
The Peters Formula:
The author suggested that this formula fit for children of 13-14 years old or younger.
eLBM = 3.8 x 0.0215 x weight(in kg)0.6469 x height(in cm)0.7236
Let us consider an example to find the lean body mass (LBM) of a children aged 13 years, whose weight is 40kg and Height is 153cm.
Step 1: Given,
Weight = 40Kg
Height = 153 cm
Step 2: Applying the values in the formula,
LBM = 3.8 x 0.0215 x weight(in kg)0.6469 x height(in cm)0.7236
LBM = 3.8 x 0.0215 x (40)0.6469 x (153)0.7236
LBM = 3.8 x 0.0215 x 10.8735 x 38.0927
LBM = 33.8405
