Chumlea et al reported equations for predicting the total body water of adults. The authors are from Wright State University, University of New Mexico and Columbia University.
Patient selection: ages from 18 to 64 years of age
Parameters:
(1) race as Black or White
(2) sex
(3) weight in kilograms
(4) stature in centimeters
(5) body mass index in kg per square meter
total body water in liters for a Black female =
= (0.22 * (weight)) + (0.24 * (stature)) - (0.05 * (age)) - 16.71
total body water in liters for a Black male =
= (0.34 * (weight)) + (0.25 * (stature)) - (0.09 * (age)) - 18.37
total body water in liters for a White female =
= (0.18 * (weight)) + (0.20 * (stature)) - (0.01 * (age)) - 10.50
total body water in liters for a White male =
= (0.50 * (weight)) - (0.62 * (BMI)) - (0.03 * (age)) + 23.04
