Prevalence of Obesity

Prevalence of Obesity is the percentage of the population estimated to be obese, defined as having a body mass index (BMI) of 30.0 or higher. BMI is equal to your weight in pounds divided by your height in inches squared and then multiplied by 703.  CDC has a calculator for BMI at http://www.cdc.gov/nccdphp/dnpa/bmi/calc-bmi.htm and determines weight status per Table 13.  Obesity is known to contribute to a variety of diseases, including heart disease, diabetes and general poor health. The data are collected by each state as part of the Behavioral Risk Factor Surveillance System of the Centers for Disease Control and Prevention.

Table 22 displays the 2006 ranks, based on 2005 data (Behavioral Risk Factor Surveillance System, Centers for Disease Control and Prevention).  The average for the United States is 24.4 percent of the adult population, up from 23.1 percent of the population in 2005 and double the rate of 11.6 percent of the population in 1990. In the United States, this means that over 53 million adults are obese, that is they have a body mass index of 30.0 or higher.  If the population of the United States could return to the weight status of 1990, there would be over 25 million fewer obese individuals.

The prevalence of obesity ranges from 17.8 percent of the population in Colorado to over 30 percent of the population in Mississippi, Louisiana and West Virginia.  In the last year, only Hawaii, Ohio and Maine experienced a decline in the prevalence of obesity but each is only a slight decline.  In South Carolina, Louisiana, Alaska, Idaho, Wyoming and West Virginia, the prevalence of obesity in their populations increased by 3 percent or more.  Since 1990, the prevalence of obesity increased in all states.  It increased the least in Connecticut, Nevada, Delaware and Florida, where an additional one of 11 people are now obese. It increased the most in Louisiana, where an additional one of six people is now obese.
