The waist-to-height ratio (WHtR, [a] or WSR: waist-to-stature ratio) is the waist circumference divided by body height, both measured in the same units. WHtR is a measure of the distribution of body fat. Higher values of WHtR indicate higher risk of obesity-related cardiovascular diseases, which are correlated with abdominal obesity. [1]
The degree of circularity of an ellipse is quantified by eccentricity, with values between 0 to 1, where 0 is a perfect circle (waist circumference same as height) and 1 is a vertical line. [1] To accommodate human shape data in a greater range, Thomas and colleagues mapped eccentricity in a range of 1 to 20 by using the equation: [1]
A study published in JAHA: Journal of the American Heart Association analyzed BRI measurements (calculated using a standard formula factoring in waist circumference and height) for more than 9,935 ...
A better measure was found to be the waist-to-height ratio. [48] A 2011 study that followed 60,000 participants for up to 13 years found that waist–hip ratio was a better predictor of ischaemic heart disease mortality. [49]

However, waist measurements are not as accurate as BMI measurements. Waist measurement (e.g., for BFP standard) is more prone to errors than measuring height and weight (e.g., for BMI standard). BMI will illustrate the best estimate of one's total body fatness, while waist measurement gives an estimate of visceral fat and risk of obesity ...
By Lisa Rapaport While obesity is associated with an increased risk for heart attacks, a new study suggests that hip and waist size may play a bigger role, particularly for women. After an average ...
New research suggests that apple-shaped women have the highest risk of developing heart disease, while hourglass-shaped women have the lowest. [52] Diabetes professionals advise that a waist measurement for a woman of over 80 cm (31 in) increases the risk of heart disease, but that ethnic background also plays a factor. [53]
