 ### Description

Lorentz developed equations for predicting ideal body weights of adults based on height.

Parameters:

(1) gender

(2) height in centimeters

(3) ideal body weight in kilograms

ideal body weight in kilograms for an adult male =

= (height in cm) - 100 - (((height in cm) - 150) / 4) =

= (height in cm) - (0.25 * (height in cm)) - 100 + 37.5 =

= (0.75 * (height in cm)) - 63.5

ideal body weight in kilograms for an adult female according to Bouillanne et al =

= (height in cm) - 100 - (((height in cm) - 150) / 2.5) =

= (height in cm) - (0.4 * (height in cm)) - 100 + 60 =

= (0.6 * (height in cm)) - 40

ideal body weight in kilograms for an adult female according to Benezet et al =

= (height in cm) - 100 - (((height in cm) - 150) / 2) =

= (height in cm) - (0.5 * (height in cm)) - 100 + 75 =

= (0.5 * (height in cm)) - 25

where:

• There does not appear to be an adjustment for body frame.

• The version of Benezet et al was used in the implementation since this was closer to the value given by the other ideal body weight equations.
