Southern obesity rates are highest
CDC survey finds West has lowest
ATLANTA - The first county-by-county survey of obesity reflects past studies that show the rate of obesity is highest in the Southeast and Appalachia.
High rates of obesity and diabetes were reported in more than 80 percent of counties in the Appalachian region that includes Kentucky, Tennessee, and West Virginia, according to the new research from the US Centers for Disease Control and Prevention.
The same problem was seen in about 75 percent of counties in Alabama, Mississippi, Louisiana, Georgia, and South Carolina.
The five counties with the highest rates were Greene and Dallas counties in Alabama and Holmes, Humphreys, and Jefferson counties in Mississippi. All are small, rural counties, and each reported obesity rates of around 44 percent or 43 percent. The national adult obesity rate is roughly 26 percent.
The statistics are estimates for 2007 - based on surveys, census figures, and other information - and include a margin of error. The obesity rates in many counties were about the same, so it is difficult to say any county or counties was the single most obese, CDC officials said.
The CDC also released yesterday county-specific data for diabetes - Type 2 is closely tied to obesity. Counties with the lowest rates of both obesity and diabetes were out West - Boulder County, Colo., Santa Fe County, N.M., and Summit County, Utah, were at the top of each list.
Just under 13 percent of people in those counties were obese, and only about 4 percent reported diabetes, the CDC found.
There are a range of possible explanations for counties in the South and Appalachia having the highest rates of obesity and diabetes, specialists said. A culture that embraces fatty, unhealthy foods and shuns exercise may be one. Genetics may be another. Income and education probably have a lot to do with it, too; people living in poor communities may not have the money to eat healthier, more expensive foods or may not have access to gyms or safe jogging trails, they said.
The Alabama counties at the top of the list are low-income, mostly African-American communities that probably ended up high on the list because the estimates assumed higher rates of obesity and diabetes in counties with those demographics, said Dr. Jim McVay, director of health promotion and chronic disease for the Alabama Department of Public Health.
