What is a key reason predictive value may be better than BMI for identifying central adiposity?

The correct choice highlights a significant limitation of BMI in assessing body composition, particularly concerning central adiposity. High subcutaneous fat in the hips can obscure abdominal fat, leading to misleading BMI results. While BMI provides a general indicator of body weight relative to height, it does not differentiate between fat distribution types.

Individuals with excessive fat stored in the hips might have a normal or even low BMI, despite having higher levels of central (abdominal) fat, which is a known risk factor for various metabolic disorders and cardiovascular diseases. Predictive value methods that take into account fat distribution more accurately assess health risks associated with central adiposity.

Other choices mention factors like muscle mass affecting BMI or potential misclassification of underweight individuals, but these do not specifically address the localization of fat and its health implications as clearly as the correct answer. Factors related to age differences can play a role in body composition, yet they do not specifically differentiate between fat distribution types like central versus peripheral fat as effectively.
