Data for white and black males and females are for non-Hispanics. Overweight and obesity in adults is body mass index ≥25 kg/m2. Obesity in adults is ≥ body mass index 30 kg/m2. In children, overweight and obesity are based on body mass index -for-age values ≥85th percentile of the 2000 Centers for Disease Control and Prevention growth charts. In children, obesity is based on body mass index -for-age values ≥95th percentile of the Centers for Disease Control and Prevention growth charts.
In January 2007, the American Medical Association’s Expert Task Force on Childhood Obesity recommended new definitions for overweight and obesity in children and adolescents (available at http://www.ama-assn.org/ama1/pub/upload/mm/433/ped_obesity_recs.pdf). However, statistics based on this new definition are not yet available.

Estimates from National Health and Nutrition Examination Survey 2005–2008 (National Center for Health Statistics) were applied to 2008 population estimates. In children, age-adjusted National Health and Nutrition Examination Survey 2007–2008 data were applied to 2006 population estimates (JAMA. 2010;303:235–241; and JAMA. 2010;303:242–249).
