Mathematical Formula & Scientific Methodology
Formula: Waist-to-Hip Ratio (WHR)
WHR = Waist Circumference / Hip CircumferenceWHO standard for identifying central android (abdominal) versus gynoid (hip/thigh) fat deposition.
Model Assumptions
- Proper measurement across widest gluteal plane
Variables & Standard Units
| Symbol | Physiological Meaning | Unit |
|---|---|---|
| Waist | Narrowest waist point or midpoint | cm |
| Hip | Widest circumference over buttocks | cm |
Scientific Limitations
- Pelvic skeletal width variation can influence ratio independent of fat mass
