Waist indices WHR, WHtR and VAI
WHR = waist / hips; WHtR = waist / height. Measure waist midway between the lowest rib and top of the pelvis after a natural exhalation, and hips at the widest point. VAI additionally uses weight, triglycerides and HDL in mmol/L following Amato (2010).

- Waist-to-Height Ratio (WHtR)
- 0.47
- Waist-to-Hip Ratio (WHR)

No index directly measures visceral fat. Low WHtR does not establish underweight; universal WHR and VAI categories are not assigned. NICE WHtR recommendations apply to adults with BMI < 35.

How it is calculated
WHR = waist / hips; WHtR = waist / height. Measure waist midway between the lowest rib and top of the pelvis after a natural exhalation, and hips at the widest point. VAI additionally uses weight, triglycerides and HDL in mmol/L following Amato (2010).
Formula
WHtR = Waist / Height; WHR = Waist / Hip; VAI (Men) = (Waist/(39.68+1.88×BMI)) × (TG/1.03) × (1.31/HDL); VAI (Women) = (Waist/(35.58+1.89×BMI)) × (TG/0.81) × (1.52/HDL).
Limits of the method
No index directly measures visceral fat. Low WHtR does not establish underweight; universal WHR and VAI categories are not assigned. NICE WHtR recommendations apply to adults with BMI < 35.
