New Cases of Diagnosed Diabetes on the Rise

State-specific data provide glimpse into geographical differences

The rate of new cases of diagnosed diabetes rose by more than 90 percent among adults over the last 10 years, according to a study by the Centers for Disease Control and Prevention (CDC).

The data, published in CDC's Morbidity and Mortality Weekly Report, show that in the past decade, the incidence (new cases) of diagnosed diabetes has increased from 4.8 per 1,000 people during 1995-1997 to 9.1 per 1,000 in 2005-2007 in 33 states.

"This dramatic increase in the number of people with diabetes highlights the increasing burden of diabetes across the country," says lead author Karen Kirtland, Ph.D., a data analyst with CDC's Division of Diabetes Translation. "This study demonstrates that we must continue to promote effective diabetes prevention efforts that include lifestyle interventions for people at risk for diabetes. Changes such as weight loss combined with moderate physical activity are important steps that individuals can take to reduce their risk for developing diabetes."

The study used data from CDC's Behavioral Risk Factor Surveillance System, and provides incidence rates of diabetes for 43 states and two U.S. territories. Only 33 states had data for both time periods, but 43 states collected data in 2005-2007.

State-specific, age-adjusted estimates of new cases of diabetes ranged from 5 per 1,000 people in Minnesota to 12.7 per 1,000 in West Virginia. The number of news cases was highest in Puerto Rico at 12.8 per 1,000. States with the highest age-adjusted incidence were predominately Southern states: Alabama, Florida, Georgia, Kentucky, Louisiana, South Carolina, Tennessee, Texas and West Virginia.

"This report documents the geographic distribution of new cases of diabetes and is consistent with previous studies showing an increase in new diabetes cases," said Kirland. "We must step up efforts to prevent and control diabetes, particularly in the Southern U.S. region where we see higher rates of diabetes, obesity and physical inactivity."

CDC, through its Division of Diabetes Translation, funds diabetes prevention and control programs in all 50 states, including the District of Columbia, and seven U.S. territories and island jurisdictions. The National Diabetes Education Program, co-sponsored by CDC and the National Institutes of Health, provides diabetes education to improve treatment for people with diabetes, promote early diagnosis and prevent or delay the onset of diabetes.
