A.1.

Prevalence of Overweight/Obesity in U.S. Children

  • a. Number and percentage of children (ages 6 to 11 years) and adolescents (ages 12 to 17 years) who were overweight, by gender and race/ethnicity— United States, Third National Health and Nutrition Examination Survey (NHANES III), 1988-1994. 

    b. Prevalence of overweight (BMI greater than or equal to 85th percentile) in Native American school-age children by gender and age, 1990-1991.

    c. Selected studies describing the prevalence of overweight in Native Americans, 1981-1993.

1Overweight is defined as a BMI (kg/m2) at or above gender- and age-specific 95th-percentile BMI cutoff points calculated at 6-month age intervals, derived respectively from National Health Examination Survey, cycles 2 and 3.
2Numbers for other racial/ethnic groups were too small for meaningful analysis.
3Confidence interval
4Excludes pregnant females and one person with an outlier sample weight.
5Total estimates include racial/ethnic groups not shown.
