What does waist-to-hip ratio assess?

The waist-to-hip ratio is a measurement that evaluates the distribution of body fat in relation to the circumference of the waist and hips. This ratio is particularly significant because it provides insight into how fat is distributed throughout the body, which is a key indicator of health risks associated with obesity.

A higher waist-to-hip ratio suggests a greater concentration of fat around the abdomen, which has been linked to a higher risk of cardiovascular diseases, type 2 diabetes, and other health-related issues. Conversely, a lower ratio indicates a healthier distribution of body fat, typically associated with lower risks for these conditions.

This measurement is especially useful because it goes beyond just assessing overall body mass. While weight can indicate whether someone is overweight or obese, understanding where that weight is distributed offers a more comprehensive view of an individual's health profile. Therefore, the waist-to-hip ratio serves as a valuable tool in identifying individuals who may be at increased risk due to their body fat distribution, making option B the most accurate answer.
