Diabetes is the percentage of adults who have been told by a health professional that they have diabetes, excluding pre-diabetes and gestational diabetes. The 2014 ranks are based on self-report data from CDC’s 2013 Behavioral Risk Factor Surveillance System (BRFSS). Because of the 2011 change in BRFSS methodology, diabetes prevalence from the 2012 Edition onward cannot be directly compared to estimates from previous years (see Methodology).
The prevalence of diabetes ranges from 6.5% of adults in Colorado to 13% of adults or more in Alabama and West Virginia. In the United States, 9.6% of adults have diabetes, about double the rate in the mid 1990s.
Diabetes is the seventh leading cause of death in the United States and contributes to the first and fourth leading causes of death, heart disease and stroke, respectively. There are 3 major types of diabetes: type 1, type 2, and gestational. Of these, type 2 diabetes is the most common and accounts for 90 to 95 percent of all diabetes cases. Type 2 diabetes is a largely preventable progressive disease that is managed through lifestyle modifications and health care interventions. It is a major cause of heart disease and stroke as well as the leading cause of kidney failure, non-traumatic lower-limb amputations, and blindness in adults. Direct medical costs for type 2 diabetes exceed $100 billion and account for $1 of every $10 spent on medical care in the United States. Costs of all types of diabetes, type one, type two, undiagnosised, gestational and prediabetes, exceeded $322 billion in 2012.
Studies have shown that the onset of type 2 diabetes can be largely prevented through losing weight, increasing physical activity, and improving dietary choices.- Type 2 diabetes is associated with numerous modifiable behaviors such as smoking, obesity, physical inactivity, and poor diet which make it an ideal target for prevention. The National Diabetes Prevention Program was created to bring evidence-based interventions to prevent diabetes to communities across the country. CDC has more information on diabetes and strategies for prevention. Additional diabetes information is available at the National Center for Chronic Disease Prevention and Health Promotion and the American Diabetes Association.
Healthy People 2020 has 16 diabetes-related objectives, which include reducing the annual number of new cases of diagnosed diabetes in the population and increasing prevention behaviors in persons at high risk for diabetes or with prediabetes. For a table of diabetes prevalence by state and education level, see Health Disparities.
