About Waist-Height Ratio

Waist to height ratio is the ratio of waist circumference to standing height. Waist to height ratio is a measure of fat distribution.
A larger waist to height ratio can be associated with higher levels of abdominal fat in the form of visceral adipose tissue which is linked to increased risks of chronic disease and mortality. 
It is recommended to keep your waist circumference to less than half your height for improved health.
