Waist-Hip Ratio: A Better Health Indicator Than BMI for Asian Adults
Why WHR Matters More Than BMI
Waist-hip ratio (WHR) measures the ratio of waist circumference to hip circumference and is a more direct measure of abdominal fat distribution than BMI. Abdominal obesity, specifically the accumulation of visceral fat around the organs, is more strongly associated with metabolic disease risk than overall body weight or BMI.
For Asian adults, where the relationship between BMI and body fat percentage is less predictive than in European populations, WHR provides additional and often more useful information about metabolic health risk. For the BMI side of this picture, see our guide to Asian BMI thresholds.
How to Measure WHR Correctly
Waist measurement: measure at the narrowest point of your torso, typically just above your belly button. Stand relaxed, exhale normally, and do not suck in. Take the measurement at the end of a normal exhale.
Hip measurement: measure at the widest point of your hips and buttocks. Keep the tape parallel to the floor and measure without compressing the skin.
WHR is your waist circumference divided by your hip circumference. Use consistent units (both in centimetres or both in inches).

Calculate Your WHRWhat Your WHR Means
WHO thresholds for health risk by sex are as follows.
For women: WHR below 0.80 is low risk. 0.80 to 0.85 is moderate risk. Above 0.85 is high risk.
For men: WHR below 0.90 is low risk. 0.90 to 0.95 is moderate risk. Above 0.95 is high risk.
Research on Asian populations suggests these thresholds may need to be adjusted downward for Asian adults in a similar way to BMI thresholds. Some studies suggest high risk thresholds of 0.80 for Asian men and 0.75 for Asian women more accurately reflect metabolic risk in Asian populations.
WHR vs BMI: Which Is Better?
Research comparing WHR and BMI as predictors of metabolic disease risk consistently shows WHR is a stronger predictor of cardiovascular disease, type 2 diabetes, and hypertension than BMI, particularly in Asian populations. A 2012 meta-analysis published in the European Heart Journal found WHR was a stronger predictor of cardiovascular risk than BMI across all populations studied.
The most accurate picture of metabolic health risk comes from using both measures together alongside blood tests (glucose, lipids) and blood pressure rather than relying on either alone.

Frequently Asked Questions
What is a good waist-hip ratio for women?
WHO guidelines classify WHR below 0.80 as low risk, 0.80 to 0.85 as moderate risk, and above 0.85 as high risk for women. Some research suggests these thresholds should be lower for Asian women (high risk above 0.75 to 0.80).
What is a good waist-hip ratio for men?
WHO guidelines classify WHR below 0.90 as low risk, 0.90 to 0.95 as moderate risk, and above 0.95 as high risk for men. Some research suggests lower thresholds for Asian men (high risk above 0.80 to 0.85).
Is WHR better than BMI?
Research consistently shows WHR is a stronger predictor of cardiovascular and metabolic disease risk than BMI. For Asian adults in particular, where BMI is a less accurate predictor of body fat percentage, WHR provides additional and more useful health risk information.
How do I measure my waist for WHR?
Measure at the narrowest point of your torso, just above the belly button. Stand relaxed, exhale normally, and measure at the end of a normal exhale. Do not suck in your stomach or compress the tape into your skin.
What does a high waist-hip ratio mean?
A high WHR indicates greater abdominal fat accumulation relative to hip size. Abdominal fat, particularly visceral fat around the organs, is associated with higher risk of type 2 diabetes, cardiovascular disease, and metabolic syndrome.
