Data and Trends

National, state and county level diabetes data from the Centers for Disease Control and Prevention

Prevalence of Diabetes in South Dakota Adults

In 2010, 41,821 or 6.9% of South Dakotans over the age of 17 had been told they have type 1 or type 2 diabetes (Source: Behavioral Risk Factor Surveillance System BRFSS). Analysis from the Centers for Disease Control and Prevention indicates approximately 25% of people with diabetes do not know they have it (Source: National Diabetes Fact Sheet, 2007), therefore an additional 13,940 South Dakota adults have undiagnosed diabetes.

Prevalence of Diabetes in South Dakotans Under 18

In 2008, BRFSS showed a prevalence of 0.2% of children and adolescents ages 0-17 with type 1 or type 2 diabetes. Using the U.S. Census Bureau's State and County QuickFacts calculations showing SD with 200,659 residents under 18, about 401 South Dakotans under 18 have type 1 or type 2 diabetes.

Prevalence of Pre-diabetes in South Dakota

According to analysis by the Centers for Disease Control and Prevention, 35% of U.S. adults aged 20 years or older, 59 million Americans, have pre-diabetes (National Diabetes Fact Sheet, 2011).  Applying this analysis to South Dakota would mean more than 200,000 South Dakotans have pre-diabetes. 

County Level Diabetes Data

The Centers for Disease Control & Prevention has released estimates of diagnosed diabetes for all counties in the United States. Derived from the agency's Behavioral Risk Factor Surveillance Survey (BRFSS) and census data, the estimates provide a clearer picture of areas within states that have higher diabetes rates. Nationally, the data indicate increased diabetes rates in areas of the Southeast and Appalachia that have traditionally been recognized as being at higher risk for many chronic diseases, including heart disease and stroke.

"These data are an important step in identifying the places in a state that have the greatest number of people affected by diabetes," said Dr. Albright. "If states know which communities or areas have more people with diabetes, they can use that information to target their efforts or tailor them to meet the needs of specific communities." CDC, through its Division of Diabetes Translation, funds Diabetes Prevention and Control Programs in all 50 states, as well as the District of Columbia and eight U.S. territories and island jurisdictions. The National Diabetes Education Program, co-sponsored by CDC and the National Institutes of Health (NIH), provides diabetes education to improve the treatment and outcomes for people with diabetes, promote early diagnosis, and prevent or delay the onset of diabetes.
