Understanding WHtR

Waist-to-Height Ratio (WHtR) is calculated by dividing waist circumference by height. It's a measure of central adiposity that helps assess cardiometabolic risk. A ratio of 0.5 or higher indicates increased health risks, with values below 0.5 considered healthy.

Clinical Considerations

According to the NIH, WHtR is more accurate than BMI for assessing health risks related to abdominal fat. It's particularly useful for identifying central adiposity across different ages and ethnic groups, providing a simple screening tool for cardiometabolic risk.

Formula

WHtR = Waist Circumference ÷ Height

NICE Guidelines (2022)

0.4 to 0.49: Healthy (OK) - No increased risk
0.5 to 0.59: Increased risk (Take Care)
0.6 or more: High risk (Take Action)

"Keep your waist to less than half your height"
