Equations of Leman et al for Total Body Water (TBW) in Nigerians Using Bioelectrical Impedance Analysis (BIA)

Description

Leman et al reported equations for estimating the total body water composition in Nigerians. The authors are from Loyola University, University of Wisconsin, and University of Ibadan in Nigeria.

Patient selection: patients from south-western Nigeria with ages from 5 to 65 years of age

Parameters:

(1) height in centimeters

(2) weight in kilograms

(3) gender

Gender	Points
male	0
female	1

total body water in kilograms for pediatric patients from 5 to 18 years =

= (0.35 * ((height)^2) / (resistance)) + (0.24 * (weight)) - (0.74 * (points for gender)) + 1.67

total body water in kilograms for patients from 5 to 65 years =

= (0.47 * ((height)^2) / (resistance)) + (0.13 * (weight)) - (1.2 * (points for gender)) + 1.93
