ATLANTA (AP) — The South tips the scales again as the nation's fattest region, according to a new government survey. Georgia and South Carolina rank in the top 10 of states listed.

More than 30 percent of adults in Mississippi, Alabama and Tennessee are considered obese. In part, experts blame Southern eating habits, poverty and demographic groups that have higher obesity rates.

Colorado was the least obese, with about 19 percent fitting that category in a random telephone survey done last year by the Centers for Disease Control and Prevention.

The South has had high death rates from heart disease and stroke, health risks that have been linked to obesity, some experts noted. The CDC study only surveyed adults, but results for kids are similar, said Dr. Miriam Vos, assistant professor of pediatrics at Atlanta's Emory School of Medicine.

"Most of the studies of obesity and children show the South has the highest rates as well," Vos said.

Why is the South so heavy? The traditional Southern diet — high in fat and fried food — may be part of the answer, said Dr. William Dietz, who heads CDC's nutrition, physical activity and obesity division.
The South also has a large concentration of rural residents and black women — two groups that tend to have higher obesity rates, he said.
High poverty rates in the South probably are another factor, said Naa Oyo Kwate, assistant professor of sociomedical sciences at Columbia University's Mailman School of Public Health.

Obesity is based on the body mass index, a calculation using height and weight. A 5-foot, 9-inch adult who weighs 203 pounds would have a BMI of 30, which is considered the threshold for obesity.
