Which measurement is better for predicting mortality compared to BMI?

Waist to Hip Ratio is a superior measurement for predicting mortality compared to Body Mass Index (BMI) because it provides a better indication of body fat distribution, which is a critical factor in assessing health risks. While BMI gives a general overview of body weight relative to height, it does not differentiate between muscle and fat, nor does it specify where fat is distributed in the body.

Research shows that excess abdominal fat, which can be effectively measured by waist circumference and the waist-to-hip ratio, is associated with a higher risk of cardiovascular disease, diabetes, and other metabolic conditions. This central fat distribution can indicate a more significant risk to health compared to overall body weight alone.

The waist-to-hip ratio specifically takes into account the proportion of fat around the abdomen compared to the hips, making it a more relevant indicator of obesity-related health issues. Therefore, it is a more nuanced approach to evaluating risk factors for mortality associated with obesity.
