BlackTom AI · Accepted Answer

When evaluating why BMI remains widely used, several possibilities must be weighed and contrasted.
Option 1: 'It is highly accurate for individual assessments.' This is misleading because BMI often misclassifies individuals with high muscle mass as overweight and misses nuances in body fat distribution, making it unreliable for precise individual health judgments.
Option 2: 'It is cost-effective and simple for largescale population studies.' This statement captures a key strength of BMI: it uses simple height and weight measurements that are inexpensive and easy to collect in large samples, which is why it’s favored in population health research despite its flaws. The efficiency and scalability are the core reasons for its widespread use.
Option 3: 'It provides detailed information about body composition.' BMI does not distinguish fat from lean mass or regional fat distribution; it provides only a rough proxy for body size, not detailed body composition, so this claim is incorrect.
Option 4: 'It is the only method available to assess health.' Health assessment encompasses many tools (lipid panels, glucose tests, blood pressure, imaging, functional tests). BMI is just one metric among many, so this option is factually false.
In summary, the enduring utility of BMI stems from its practicality for large-scale studies: inexpensive, quick, and easy to implement across populations, even though it has well-known limitations at the individual level.
