What best describes BMI limitations in health assessment?

• A. It is an indirect measure and does not account for race, ethnicity, gender, or structural differences
• B. It directly measures body fat
• C. It measures resting metabolic rate
• D. It reflects bone density accurately

Answer: (C)

BMI uses height and weight to estimate body fat, but it doesn’t measure fat directly and has notable limitations. It cannot distinguish between muscle and fat, so muscular individuals may have a high BMI despite low body fat. It also doesn’t reveal where fat is distributed, which matters for health risk. In addition, BMI doesn’t account for differences due to age, sex, race or ethnicity, or body frame, so its interpretation can vary across populations. It does not measure resting metabolic rate or bone density. Therefore, describing BMI as an indirect measure that does not account for race, ethnicity, gender, or structural differences captures its main limitation.
