Which measurement tool divides waist circumference by hip circumference?

The correct answer is the measurement tool that divides waist circumference by hip circumference, known as the waist-to-hip ratio. This tool is valuable in assessing body fat distribution, particularly the relative amounts of fat stored in the waist compared to the hips. A higher waist-to-hip ratio indicates a greater proportion of central or abdominal fat, which is associated with an increased risk of cardiovascular diseases and metabolic disorders. Therefore, this ratio serves as an important indicator for evaluating health risks related to body composition.

In contrast, body mass index (BMI) is a different measurement that relates weight to height but does not specifically assess body fat distribution. The waist-to-height ratio considers the relationship between waist circumference and height, providing another perspective on health risk but not using hip circumference. Body fat percentage measures the actual amount of body fat in relation to overall body weight, rather than comparing the waist and hip measurements as the waist-to-hip ratio does.
