Waist-to-Hip Ratio

WHO health risk assessment from WHR

📏Waist-to-Hip Ratio

Waist-to-hip ratio (WHR) compares the circumference of the waist to the hips. High WHR indicates central (abdominal/visceral) obesity, which is more strongly associated with cardiovascular disease and metabolic syndrome than peripheral fat.

  1. 1WHR = Waist circumference / Hip circumference
  2. 2Measure waist at narrowest point (navel level)
  3. 3Measure hips at widest point of buttocks
  4. 4WHO thresholds: men > 0.90 = high risk; women > 0.85 = high risk
Male: waist 92cm · hip 100cm=WHR = 0.92 → high riskAbove 0.90 threshold for men
SexLow riskModerate riskHigh risk
Male< 0.900.90–0.95> 0.95
Female< 0.800.80–0.85> 0.85

Fun Fact

WHR is a stronger predictor of heart attack risk than BMI. A landmark INTERHEART study (52 countries, 27,000 people) found WHR predicted 20% of heart attack risk independently of all other factors.
