Which statement is true regarding BMI calculation guidelines for athletes?

• A. Height should be measured without shoes; the athlete should wear minimal clothing; a regularly calibrated scale should be used; BMI < 18.5 kg/m2 indicates underweight
• B. Height should be measured with shoes on; the athlete should wear heavy clothing; an uncalibrated scale should be used
• C. There are no BMI cutoff points for under 18-year-olds
• D. Preadolescent athletes should have BMI evaluated routinely

Answer: (B)

Accurate BMI calculation depends on precise, standardized measurements and clear interpretation. Height should be measured with shoes off and in light clothing, using a properly calibrated scale or stadiometer, and weight should be taken with minimal clothing on a regularly calibrated scale. Following these procedures ensures the BMI value truly reflects body mass relative to height; measuring height with shoes on, wearing heavy clothing, and using an uncalibrated scale would introduce systematic errors and distort the BMI. For interpretation, a BMI below 18.5 kg/m2 is commonly used to indicate underweight in adults. For younger individuals, BMI assessment uses age- and sex-specific percentiles rather than a single cutoff. Routine BMI evaluation in preadolescents can be discussed within the broader context of growth monitoring, but it isn’t a blanket requirement in all athletic settings.
