Adult Obesity Facts

Obesity is common, serious and costly

  • More than one-third (or 78.6 million) of U.S. adults are obese. [Read abstract Journal of American Medicine (JAMA)External Web Site Icon]
  • Obesity-related conditions include heart disease, stroke, type 2 diabetes and certain types of cancer, some of the leading causes of preventable death. [Read guidelinesExternal Web Site Icon]
  • The estimated annual medical cost of obesity in the U.S. was $147 billion in 2008 U.S. dollars; the medical costs for people who are obese were $1,429 higher than those of normal weight. [Read summaryExternal Web Site Icon]

Obesity affects some groups more than others

  • Non-Hispanic blacks have the highest age-adjusted rates of obesity (47.8%) followed by Hispanics (42.5%), non-Hispanic whites (32.6%), and non-Hispanic Asians (10.8%)
  • Obesity is higher among middle age adults, 40-59 years old (39.5%) than among younger adults, age 20-39 (30.3%) or adults over 60 or above (35.4%) adults.

Obesity and socioeconomic status

  • Among non-Hispanic black and Mexican-American men, those with higher incomes are more likely to be obese than those with low income.
  • Higher income women are less likely to be obese than low-income women.
  • There is no significant relationship between obesity and education among men. Among women, however, there is a trend—those with college degrees are less likely to be obese compared with less educated women.

Obesity prevalence in 2012 varies across states and regions

  • By state, obesity prevalence ranged from 20.5% in Colorado to 34.7% in Louisiana in 2012. No state had a prevalence of obesity less than 20%. Nine states and the District of Columbia had prevalence between 20-25%. Thirteen states (Alabama, Arkansas, Indiana, Iowa, Kentucky, Louisiana, Michigan, Mississippi, Ohio, Oklahoma, South Carolina, Tennessee, and West Virginia) had a prevalence equal to or greater than 30%.
  • Higher prevalence of adult obesity was found in the Midwest (29.5%) and the South (29.4%). Lower prevalence was observed in the Northeast (25.3%) and the West (25.1%).

The U.S. map has been color coded to indicate the range of obesity prevalence in each state in 2012. No state had an obesity prevalence between 15% to less than 20%. States that had an obesity prevalence between 20% to less than 25% are: Colorado, District of Columbia, Hawaii, Massachusetts, Montana, New Jersey, New York, Utah, Vermont, and Wyoming. States that had an obesity prevalence between 25% to less than 30% are: Alaska, Arizona, California, Connecticut, Delaware, Florida, Georgia, Idaho, Illinois, Kansas, Maine, Maryland, Minnesota, Missouri, Nebraska, Nevada, New Hampshire, New Mexico, North Carolina, North Dakota, Oregon, Pennsylvania, Rhode Island, South Dakota, Texas, Virginia, Washington, and Wisconsin. States that had an obesity prevalence between 30% to less than 35% are: Alabama, Arkansas, Indiana, Iowa, Kentucky, Louisiana, Michigan, Mississippi, Ohio, Oklahoma, South Carolina, Tennessee, and West Virginia. No state had an obesity prevalence equal to or greater than 35%.

The History of State Obesity Prevalence

  • There was a dramatic increase in obesity in the United States from 1990 through 2010.
  • State prevalences prior to 2011 is provided for historical information only.  Historical rates should not be compared to rates from 2011 and forward due to changes in survey methods.
  • No state met the nation's Healthy People 2010External Web Site Icon goal to lower obesity prevalence to 15%. Rather, in 2010, there were 12 states with an obesity prevalence of 30%. In 2000, no state had an obesity prevalence of 30% or more. [Read article]
