Abbreviation: BMI, body mass index (calculated as weight in kilograms divided by height in meters squared).

^aData from the National Health and Nutrition Examination Survey estimates are weighted.

^bSee Table 1 for unweighted sample sizes and eTable 1 in the Supplement for unweighted No. of persons with obesity or severe obesity by age, sex, education of household head, and race and Hispanic origin.

^cIncludes other race and Hispanic origin groups not shown separately.

^dObesity was defined as at or above the sex-specific 95th percentile of US Centers for Disease Control and Prevention (CDC) BMI-for-age growth charts.

^eEstimate potentially unreliable, CI >5 percentage points and relative CI width >130%.

^fStandard error degrees of freedom <8.

^gSevere obesity was defined as ≥120% of the sex-specific 95th percentile of CDC BMI-for-age growth charts.

^hLower limit of CI could not be calculated.
