Highest Rates of Obesity, Diabetes in the South, Appalachia, and Some Tribal Lands

Posted Nov 19 2009 10:03pm

Wide sections of the Southeast, Appalachia, and some tribal lands in the West and Northern Plains have the nation's highest rates of obesity and diabetes, according to estimates released today by the Centers for Disease Control and Prevention. In many counties in those regions, rates of diagnosed diabetes exceed 10 percent and obesity prevalence is more than 30 percent.

The estimates, in this week's Morbidity and Mortality Weekly Report, are the first to provide county-level snapshots of obesity across the United States. They also update diabetes county-level estimates released in 2008.

Eighty-one percent of counties in the Appalachian region that includes Kentucky, Tennessee, and West Virginia have high rates of diabetes and obesity. So do three-quarters of counties in the southern region that includes Alabama, Georgia, Louisiana, Mississippi, and South Carolina.

"Diabetes is costly in human and economic terms, and it's urgent that we take action to prevent and control this serious disease," said Dr. Ann Albright, director of CDC's Division of Diabetes Translation. "The study shows strong regional patterns of diabetes and can help focus prevention efforts where they are most needed."

The estimates come from the agency's Behavioral Risk Factor Surveillance System (BRFSS), which uses self-reported data from state-based adult telephone surveys, and 2007 census information. The information may help public health workers, health care providers, community organizations, and policymakers focus on high-risk regions to prevent type 2 diabetes and its complications as well as other chronic diseases linked to obesity, including heart disease, stroke, and some cancers.

The proportion of U.S. adults who are obese was 26.1 percent in 2008, according to BRFSS data. CDC estimates that nearly 8 percent of the population, or about 24 million people, have diabetes. Of these, 5.7 million are undiagnosed.

"The small-area estimates for obesity will be an important tool to help communities better understand and battle this serious public health problem. Communities are in the best position to prevent and reduce obesity among their citizens through innovative programs," said Dr. William H. Dietz, director of CDC's Division of Nutrition, Physical Activity and Obesity.

The medical costs of obesity reached an estimated $147 billion in 2008, and the medical costs of diabetes were $116 billion. People with diagnosed diabetes have medical costs that are 2.3 times higher than those without the disease.

Obesity is one of several factors linked to type 2 diabetes. Where people live, how much money they earn, their culture and their family history also play a role. An unhealthy diet, lack of physical activity, and socioeconomic factors contribute to both obesity and type 2 diabetes as well as to complications of diabetes. Some population groups also are at higher risk, including a number of racial and ethnic minorities.

CDC and its partners are working on a variety of initiatives to prevent type 2 diabetes and to reduce obesity. CDC has recommended 24 community strategies to prevent obesity, from providing greater access to healthy foods to redesigning communities to encourage more physical activity. The agency is also in a new partnership with state, federal, and nonprofit agencies targeting health disparities in Mississippi, which has the nation's highest obesity rate and one of the highest rates of diabetes. CDC's national diabetes prevention and control program provides resources and technical assistance to state health departments, national organizations, and communities.
