How it's calculated

Waist-to-hip ratio = waist ÷ hip circumference
WHO (2008): substantially increased risk at ≥ 0.90 (men), ≥ 0.85 (women)
Waist-to-height ratio = waist ÷ height (aim under 0.5)

Fat carried around the middle is more closely linked with heart disease and type 2 diabetes than fat on the hips, which is why this ratio adds something BMI misses. The WHO cut-offs are for adults; the moderate band is a common guide 0.05 below them, not part of the WHO definition. Use the same tape and the same points each time.
