Back to Derived Variables and Risk Factors.

*Body mass index is computed as weight in kilograms divided by height in meters squared:(kg/ m2).
BMI is an intermediate variable used in defining overweight and obesity.
Underweight=BMI less than 18.5, Recommended Range=BMI 18.5 to 24.9, Overweight=BMI 25.0 to 29.9 and Obese=BMI 30 or greater.

PLEASE NOTE: Due to changes in the weighting methodology and other factors, results from 2021 are NOT comparable to 2010
and earlier years.

***The estimate was suppressed because it did not meet statistical reliability standards. See BRFSS 2021 Annual Results Technical Notes for more details.
