  1. Which A1C range meets the ADA criteria for prediabetes?

    Answer: 5.7–6.4%

    ADA defines prediabetes as an A1C of 5.7–6.4%. An A1C of 6.5% or higher on repeat testing meets the criteria for diabetes.

  2. A fasting plasma glucose of 112 mg/dL is classified as which of the following?

    Answer: Impaired fasting glucose

    Impaired fasting glucose is a fasting plasma glucose of 100–125 mg/dL. Impaired glucose tolerance refers to a 2-hour OGTT value of 140–199 mg/dL. A fasting value of 126 mg/dL or higher indicates diabetes.

  3. The Diabetes Prevention Program lifestyle intervention targeted which combination of goals?

    Answer: At least 7% weight loss and 150 minutes of moderate activity per week

    The DPP lifestyle program aimed for at least 7% body weight loss and at least 150 minutes per week of moderate-intensity physical activity, such as brisk walking.

  4. In the original Diabetes Prevention Program trial, by approximately how much did intensive lifestyle intervention reduce the progression to type 2 diabetes compared with placebo?

    Answer: About 58%

    Lifestyle intervention reduced the incidence of diabetes by 58% over about 3 years, compared with a 31% reduction with metformin. Lifestyle was therefore more effective than metformin overall.

  5. Metformin for diabetes prevention is most strongly considered in which person with prediabetes?

    Answer: A 45-year-old with a BMI of 36 and a history of gestational diabetes

    ADA suggests considering metformin for people with prediabetes who are younger than 60, have a BMI of 35 or higher, or have a history of GDM. These groups showed the greatest benefit in the DPP.

  6. Which patient should be screened for prediabetes and diabetes according to ADA risk-based criteria?

    Answer: An adult with overweight (BMI 25 or higher) and a first-degree relative with diabetes

    ADA recommends testing adults with overweight or obesity who have one or more risk factors, such as a first-degree relative with diabetes, physical inactivity, hypertension, or a history of GDM. Everyone should also be screened starting at age 35.
