Diabetes Standards of Care and Resources for Clinicians and Educators
Diabetes Prevention
People may have prediabetes for many years and not be aware of it. Of the individuals who have prediabetes, many will progress to type 2 diabetes over time. Identifying prediabetes gives the patient and health care provider an opportunity to engage in an effort to prevent or delay the onset of diabetes. This can be done by implementing lifestyle change interventions, such as reducing weight and increasing physical activity, and/or taking medication.

Clinical Practice Recommendations
Recommendations for Diabetes Prevention
Screening methods for prediabetes are described in the Diabetes Screening and Prevention Algorithm [PDF – 157 KB]. The diagnosis of prediabetes can be made based on any of the following test results:
- A1C level of 5.7% to 6.4%
- Fasting plasma glucose level of 100 mg/dL to 125 mg/dL
- 2-hour plasma glucose value of 140 mg/dL to 199 mg/dL during a 75-gm oral glucose tolerance test
People with values in the upper ends of these test ranges have a greater risk of developing diabetes than people with values at the lower ends.
Lifestyle Interventions
The National Institutes of Health Diabetes Prevention Program (DPP) clinical trial found that an intensive lifestyle intervention (ILI) lowered diabetes incidence by 58% in individuals at high risk for diabetes.1 The 16-session ILI program established a weight loss goal of 7% from baseline and a physical activity goal of 150 minutes per week. The reduction in diabetes incidence with the ILI was similar in all racial subgroups, including American Indian people.
The Special Diabetes Program for Indians Diabetes Prevention demonstration project showed that a Native Lifestyle Balance Curriculum (modified 16-session, 6-month DPP ILI curriculum) could be successfully implemented in American Indian/Alaska Native (AI/AN) communities.2
Resources on lifestyle intervention programs for diabetes prevention:
- The Centers for Disease Control and Prevention (CDC) offers curricula and formal recognition of lifestyle change programs through the National DPP. Exit Disclaimer: You Are Leaving www.ihs.gov
- The Medicare Diabetes Prevention Program Expanded Model Exit Disclaimer: You Are Leaving www.ihs.gov offers reimbursement for Medicare beneficiaries participating in CDC-recognized diabetes prevention programs.
Metformin
Medications can prevent or delay the progression to diabetes. Metformin, an anti-hyperglycemic agent, reduced diabetes incidence by 31% in the National Institutes of Health DPP trial.1 Metformin is most effective for diabetes prevention in adults with prediabetes and any of the following characteristics:
- Body mass index of at least 35 kg/m2
- Age less than 60 years
- History of gestational diabetes mellitus
Note: Metformin is U.S. Food and Drug Administration (FDA)-approved for hyperglycemia treatment in people with type 2 diabetes, but not for diabetes prevention.
Other Medications
Several other medications have been shown to prevent or delay diabetes in people with prediabetes. Weight loss drugs, such as orlistat and topiramate-phentermine, and anti-diabetes agents, including GLP-1 receptor agonists, dual GIP/GLP-1 receptor agonists, acarbose, and pioglitazone reduce the rate of diabetes development in people at-risk for diabetes. However, there are currently no FDA-approved medications for diabetes prevention. Providers should discuss the risks and benefits of these agents with patients before prescribing them for diabetes prevention.
