More than one in five young adults are obese. Obesity in adults is associated with increased risk for a wide variety of poor health outcomes, including diabetes, stroke, heart disease, arthritis, and certain cancers.52 Eating habits and physical activity patterns that contribute to obesity are often established during adolescence and young adulthood.53 In addition to individual factors, such as diet and physical activity, social, economic, and environmental forces may contribute to the high prevalence of obesity.54
NOTE: Obesity is defined as body mass index ≥ 30 kilograms per meter squared (kg/m2). From 1988 to 1994, the 1977 Office of Management and Budget (OMB) standards were used to classify persons into one of four racial groups: White, Black, American Indian or Alaskan Native, or Asian or Pacific Islander. For 1999–2010, 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 are racial groups not shown separately. Beginning in 1999, racial categories represent persons reporting only one race. Data from 1999 onward are not directly comparable with data from earlier years. Persons of Mexican origin may be of any race.
