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.
