Results from the 2013–2014 National Health and Nutrition Examination Survey (NHANES), using measured heights and weights, indicate that an estimated 17.2% of U.S. children and adolescents aged 2–
19 years are obese and another 16.2% are overweight.
Body mass index (BMI), expressed as weight in kilograms divided by height in meters squared (kg/m2), is commonly used to classify obesity among adults and is also recommended for use with children and adolescents. Cutoff criteria are based on the sex-specific BMI-for-age 2000 CDC Growth Charts for the United States. Based on current recommendations from expert committees, children and adolescents with BMI values at or above the 95th percentile of the growth charts are categorized as obese. This differs from previous years in which children and adolescents above this cutoff were labeled overweight. This change in terminology reflects the labels used by organizations such as the Institute of Medicine and the American Academy of Pediatrics. For more information, see “Changes in Terminology for Childhood Overweight and Obesity”.
Table 1 shows the prevalence of overweight and obesity among youth aged 2–19 years from 1971–1974 through 2013–2014. The estimates for all children are shown by age in the figure.
Estimates of the prevalence of childhood obesity during the 1960s are available for certain age groups. Table 2 shows the prevalence of obesity among youth aged 2–5, 6–11, and 12–19 years since 1963–1965, by sex and age. The figure shows trends in obesity by age.
Table 3 shows the prevalence of obesity by race and Hispanic origin among youth aged 2–19 since 1988–1994.
Although BMI is widely used as a measure of body fat, at a given BMI level, body fat may vary by sex, age, and race and Hispanic origin. For example, some research suggests that Asian persons may have more body fat than white persons, especially at lower BMIs, and that health risks may begin at a lower BMI among Asian persons compared with others.
NHANES, conducted by the National Center for Health Statistics, is a stratified, multistage probability sample of the civilian noninstitutionalized population of the United States. A household interview and a physical examination are conducted for each survey participant. During the physical examination, conducted in a mobile examination center, height and weight are measured as part of a more comprehensive set of body measurements. These measurements are taken by trained health technicians, using standardized measuring procedures and equipment. Observations for persons missing a valid height or weight measurement and for pregnant females were not included in the data analysis.
