Durnin & Womersley Method
PRO+A 4-site skinfold method that accounts for age-related changes in body composition using age-specific equations.
Method Overview
Developed by Durnin and Womersley in 1974, this method uses age-specific equations to account for changes in fat distribution patterns across different age groups.
- Accuracy: ±3.5-5% with proper technique
- Age-specific equations
- Accounts for age-related changes
Measurement Protocol
Measurement Sites
Required Sites:
- Biceps (front of upper arm)
- Triceps (back of upper arm)
- Subscapular (under shoulder blade)
- Suprailiac (above hip bone)
Measurement Tips:
- Take measurements on the right side
- Mark measurement sites before starting
- Use consistent caliper pressure
- Wait briefly before reading the caliper
- Record age accurately for equation selection
