Waist to hip ratio
theory/evidence
Research has indicated that body shape may be related to an increased risk of certain diseases, such as cardiovascular disease, diabetes, and high cholesterol. An "apple-shape" (weight carried primarily around the waist) seems to have a higher risk of these diseases than a "pear-shape" (weight carried primarily around the hips.) These shapes can be defined by comparing waist circumference to hip circumference, or waist-hip ration (WHR).
According to the American Heart Association, WHR is less accurate than body mass index (BMI) or waist circumference and is no longer recommended.
