DATA SOURCE
19-3c National Health and Nutrition Examination Survey (NHANES), CDC, NCHS.

Additional Information

Numerator: Number of persons aged 6 to 19 years with a BMI at or above the gender-and age-specific 95th percentile from the CDC Growth Charts; United States.

Denominator: Number of persons aged 6 to 19 years.

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 children and adolescents until a better measure is developed. There is a prepubertal increase in subcutaneous fat that is lost during adolescence in boys, while in girls, fat deposition continues. There also is a differential increase in muscle (or lean body mass) by gender during puberty. Thus, without measures of sexual maturity, measures of body fat and body weight are equally difficult to interpret in preadolescents and adolescents.

In 2000, the 1977 NCHS Growth Charts were revised to consider additional large, nationally representative samples of children aged 2 to 20 years from the 1976-80 NHANES and the 1988-94 NHANES and to provide BMI for age in lieu of weight for age. When extrapolated to age 20 years, the gender- and age-specific 95th percentile of BMI from the Revised CDC Growth Charts approximates a BMI of 30. Thus, the 95th percentiles of BMI for children aged 6 to 11 years and for adolescents aged 12 to 19 years were chosen to estimate the prevalence of overweight and obesity for this objective.
