Patient selection: from 15 to 90 years of age (races not defined)
Parameters:
(1) age in years
(2) gender
(3) body weight in kilograms
(4) total body water in liters
The equations were reported as (total body water) * 100 / (body weight).
(total body water for an adult male) * (100 percent) / (body weight) =
= 79.45 – (0.24 * (body weight)) – (0.15 * (age))
(total body water for an adult male) * (100 percent) / (body weight) =
= 69.81 – (0.26 * (body weight)) – (0.12 * (age))
The following equations have been rewritten to express total body water.
total body water for an adult male =
= (0.7945 * (body weight)) – (0.0024 * ((body weight)^2)) – (0.0015 * (age) * (body weight))
total body water for an adult female =
= (0.6981 * (body weight)) – (0.0026 * ((body weight)^2)) – (0.0012 * (age) * (body weight))
