Equations of Larsson et al for Estimating Body Fat in Adults Based on Height, Weight and Waist Circumference

Purpose: To estimate the body fat of an adult using height, weight and waist circumference in the equations of Larsson et al.

Description

Larsson et al correlated a patient's age, height and weight with body fat in adults determined by dual X-ray absorptiometry (DEXA). The authors are from Goteborg University and University Hospital Orebro in Sweden.


Patient selection: adults from 30 to 62 years of age, almost entirely White

 

Parameters:

(1) gender of the patient

(2) body height in meters

(3) body weight in kilograms

(4) waist circumference in cm

 

body fat for a male in kg =

= (0.4567 * (waist circumference)) + (0.2572 * (weight)) - (13.49 * (height)) + 18.38

 

body fat for a female in kg =

= (0.1069 * (waist circumference)) + (0.6276 * (weight)) - (25.69 * (height)) + 15.20

 

NOTE: The equation for females give a result comparable to that given by 02.03.30. However, the equation for males gave results about twice the expected value. Using 0.04567 for the waist circumference factor gave a closer value.
