Prediabetes is a serious health condition in which blood sugar levels are higher than normal, but not high enough yet to be diagnosed as type 2 diabetes. A person with prediabetes is at high risk of type 2 diabetes, heart disease, and stroke. An estimated 96 million US adults—more than 1 in 3—have prediabetes, and more than 8 in 10 of them don’t know they have it.
CDC’s Division of Diabetes Translation supports programs and policies that help people prevent type 2 diabetes and improve the health of everyone living with diabetes. The CDC-led National Diabetes Prevention Program (National DPP) is a public-private partnership working to build a nationwide system to deliver an affordable, evidence-based lifestyle change program proven to prevent or delay type 2 diabetes. Participants in the program learn to make healthy food choices, be more physically active, and find ways to cope with problems and stress. These lifestyle changes can cut their risk of developing type 2 diabetes by as much as 58% (71% for those 60 or older).
In April 2018, the lifestyle change program became a covered service for Medicare beneficiaries with prediabetes. This is the first preventive service model from the Center for Medicare & Medicaid Innovation that has been expanded into the Medicare program—a landmark for public health.
CDC funds all 50 states, the District of Columbia, national organizations, and several large city health departments to:
- Improve awareness of prediabetes among health care providers and people at risk.
- Increase access to and enrollment in the National DPP lifestyle change program.
- Increase coverage for the lifestyle change program among public and private payers and employers.
- Improve screening and testing for prediabetes and refer people who are eligible to the lifestyle change program.
In partnership with the American Medical Association and the Ad Council, CDC leads the award-winning Do I Have Prediabetes? campaign. The campaign is the first ever to raise awareness across the nation about prediabetes. The campaign reaches millions of people and encourages them to take a 1-minute test at DoIHavePrediabetes.org. The campaign website also links to organizations delivering the National DPP lifestyle change program.
