To be eligible for referral to a CDC-recognized lifestyle change program, patients must meet the following requirements:
- Be at least 18 years old and
- Be overweight (body mass index =24; =22 if Asian) and
- Have no previous diagnosis of type 1 or type 2 diabetes and
- Have a blood test result in the prediabetes range within the past year:
- Hemoglobin A1C: 5.7%–6.4% or
- Fasting plasma glucose: 100–125 mg/dL or
- Two-hour plasma glucose (after a 75 gm glucose load): 140–199 mg/dL or
- Be previously diagnosed with gestational diabetes
Prediabetes can be diagnosed via oral glucose tolerance tests, fasting blood glucose tests, or an A1C test. Blood-based testing is the most accurate way to determine if a patient has prediabetes.
