Equation of Aglago et al for Estimating Total Body Water (TBW) in North African Adults

Patient selection: age from 18 to 64 years

Methods of analysis for body water: D2O (deuterium oxide)

Parameters:

(1) height in centimeters

(2) resistance in Ohms from bioelectric impedance analysis (BIA)

(3) sex (male 1, female 0)

(4) weight in kilograms

(5) age in years

total body water in liters =

= (0.267 * ((height)^2) / (resistance)) + (4.42 * (points for sex)) + (0.225 * (weight)) - (0.052 * (age)) + 5.68
