America's Children: Key National Indicators of Well-Being, 2017

Obesity

Children with obesity often become adults with obesity, with increased risks for a wide variety of poor health outcomes, including diabetes, stroke, heart disease, arthritis, and certain cancers.148, 149 The consequences of obesity for children and adolescents are often psychosocial, but also include high blood pressure, diabetes, early puberty, and asthma.149, 150 The prevalence of obesity among U.S. children changed relatively little from the early 1960s through 1980; however, after 1980 it increased sharply.151 In addition to individual factors, such as diet and physical activity, social, economic, and environmental forces (such as family, school, or community factors that promote more eating out and less physical activity) may have contributed to the increased prevalence of obesity.152

NOTE: Previously a body mass index (BMI) at or above the 95th percentile of the sex-specific BMI growth charts was termed overweight (http://www.cdc.gov/growthcharts). Beginning with America's Children, 2010, a BMI at or above the 95th percentile is termed obese to be consistent with other National Center for Health Statistics publications. Estimates of persons with obesity are comparable to estimates of overweight in past reports.153 From 1976 to 1994, the 1977 U.S. Office of Management and Budget (OMB) Standards for Data on Race and Ethnicity were used to classify persons into one of the following four racial groups: White, Black, American Indian or Alaskan Native, or Asian or Pacific Islander. For 1999–2014, the revised 1997 OMB standards were used. Persons could select one or more of five racial groups: White, Black or African American, American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander. Included in the total but not shown separately are American Indian or Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, and "Two or more races." Beginning in 1999, those in each racial category represent those reporting only one race. Data from 1999 onward are not directly comparable with data from earlier years. Data on race and Hispanic origin are collected separately but are combined for reporting. Persons of Mexican origin may be of any race. From 1976 to 2006, the National Health and Nutrition Examination Survey (NHANES) sample was designed to provide estimates specifically for persons of Mexican origin. Beginning in 2007, NHANES allows for reporting of both total Hispanics and Mexican Americans; however, estimates reported here are for Mexican Americans to be consistent with earlier years.

  • In 1976–1980, 6 percent of children ages 6–17 had obesity. This percentage rose to 11 percent in 1988–1994 then to 16 percent in 1999–2002.
  • From 1999–2002 through 2011–2014, the percentage of children ages 6–17 with obesity did not differ statistically, ranging from 16 to 20 percent.
  • In 2011–2014, about 18 percent of children ages 6–11 and 21 percent of adolescents ages 12–17 had obesity.
  • In 2011–2014, Mexican American (25 percent) and Black, non-Hispanic (23 percent) children ages 6–17 were more likely to have obesity than White, non-Hispanic (17 percent) or Asian, non-Hispanic (10 percent) children ages 6–17.
  • In 2011–2014, there was no statistical difference between the percentages of boys (19 percent) and girls (20 percent) ages 6–17 who had obesity.
