Additional Information

Numerator: Number of persons aged 20 years and older with a BMI equal to or greater than 30.0

Denominator: Number of persons aged 20 years and older.

Population Targeted: U.S. civilian, noninstitutionalized population.

The NHANES obtains measured weights and heights without shoes. BMI is calculated by dividing weight in kilograms by the square of height in meters.

BMI will be used as a proxy for overweight and obesity in adults until a better measure of body fat is developed. In 1997, a Consultation on Obesity convened by the World Health Organization recommended standardizing the classification of overweight and obesity. Overweight was defined as a BMI of 25.0 or greater and obesity was defined as a BMI of 30.0 or greater. Further classification of obesity was made as follows: 30.0-34.9 was defined as Class I obesity, 35.0-39.9 as Class II, and 40.0 or greater as Class III.

The Expert Panel on the Identification, Evaluation, and Treatment of Overweight and Obesity in Adults, convened by NIH, recently adopted general concepts of the World Health Organization classification system1, 2 and it has now been endorsed by more than 50 professional medical societies, consumer groups, and government agencies. For this objective, therefore, a BMI cutoff point of 30.0 was chosen for adults aged 20 years and older. Since 1960, essentially all of the increased prevalence of overweight and obesity in adults in the United States has occurred at a BMI greater than or equal to 30.0.

Pregnant women are excluded from the numerator and denominator.

Data (except those for people with chronic conditions) are age adjusted to the 2000 standard population using the age groups 20-39, 40-59, and 60 years and over. Age-adjusted rates are weighted sums of age-specific rates.
