The waist-to-height ratio of a person ( WHtR ), also called waist-to-stature ratio ( WSR ), is defined as the circumference Their waist is divided by their height, both measured in the same unit. WHtR is a measure of the distribution of body fat. A higher WHTR score indicates a higher risk of cardiovascular disease associated with obesity; it correlates with abdominal obesity.
A 2010 study that followed 11,000 subjects for up to eight years concluded that WHTR is a much better measure of risk of heart attack, stroke or death than the more widely used body mass index. However, a study in 2011 that followed 60,000 participants up to 13 years found that waist-to-hip ratio (when adjusted for BMI) was a better predictor of death of ischemic heart disease than WHTR.
In contrast, WHTR is not a predictor of new-onset diabetes mellitus in at least one study.
A WHtR of more than 0.5 is very important and signifies an increased risk; the 2010 systematic review of published studies concludes that "WHtR may be beneficial because it avoids the necessity of certain age, gender and ethnic restrictions". For people under 40 the critical value is 0.5, for people aged 40-50 the critical value is between 0.5 and 0.6, and for those above 50 critical values ​​starting at 0.6.
