Prevent Type 2 Diabetes

The Issue

About 84 million Americans age 18 years or older have prediabetes, and 30.3 million individuals have diabetes.  Among those with diabetes, approximately 95 percent have type 2 diabetes — a condition that can be prevented or delayed with lifestyle changes. People with diabetes and prediabetes are at higher risk for developing other serious health problems, including heart disease and stroke.

Total direct and indirect costs for diabetes in the United States in 2017 were estimated at $327 billion.


Plan an Evidence-Based Intervention

Following is the intervention to prevent type 2 diabetes identified by the CDC as having a proven evidence base for improving health outcomes and controlling health care costs:

  • Expand access to the National Diabetes Prevention Program (the National DPP), which supports a year-long lifestyle change program to prevent or delay onset of type 2 diabetes in people with prediabetes or at high risk for type 2 diabetes.
