Trends by State 1985–2008
Obesity is defined as a body mass index (BMI) of 30 or greater. BMI is calculated from a person’s weight and height and provides a reasonable indicator of body fatness and weight categories that may lead to health problems.
Obesity is a major risk factor for cardiovascular disease, certain types of cancer, and type 2 diabetes.
During the past 20 years there has been a dramatic increase in obesity in the United States.
In 2008, only one state (Colorado) had a prevalence of obesity less than 20%.
Thirty-two states had a prevalence equal to or greater than 25%; six of these states (Alabama, Mississippi, Oklahoma, South Carolina, Tennessee, and West Virginia ) had a prevalence of obesity equal to or greater than 30%.

New Obesity Data Shows Blacks Have the Highest Rates of Obesity.
- Blacks had 51 percent higher prevalence of obesity, and Hispanics had 21 percent higher obesity prevalence compared with whites.
- Greater prevalences of obesity for blacks and whites were found in the South and Midwest than in the West and Northeast.
