Mathematical Formula & Scientific Methodology

Formula: Waist-to-Height Ratio (WHtR)

WHtR = Waist Circumference / Stature

Cardiovascular meta-analyses show WHtR is superior to BMI in predicting visceral adiposity and type 2 diabetes risk.

Model Assumptions

  • Measurement taken at the end of normal expiration

Scientific Limitations

  • Does not distinguish subcutaneous abdominal fat from deep visceral fat

Key Finding: Body Roundness Index (BRI) models human body as an ellipse using waist and height, outperforming BMI in estimating visceral adiposity and all-cause mortality risk.
