Body Density Equations: Durnin & Womersley

These formula developed by Durnin and Womersley (1974) can be used to estimate body fat percentage using skinfold test results. The Durnin and Womersley formula is a general equation with limited population specificity since it was developed from a heterogeneous group of varying ages.

The calculation of body fat % involves measuring four skinfold sites, triceps, biceps, subscapular and suprailiac, and substitute the log of their sum into one of the following equations, Where D = predicted density of the body (g/ml), and L = log of the total of the 4 skinfolds (mm). The density value can then converted to Percent bodyfat (%BF) using the Siri Equation. There are more body density equations and other equations for measuring body fat using skinfold measures.
