Criteria for testing for diabetes or prediabetes in asymptomatic adults
| 1. Testing should be considered in all adults who are overweight (BMI ≥25 kg/m2 or ≥23 kg/m2 in Asian Americans) and have additional risk factors: |
| • physical inactivity |
| • first-degree relative with diabetes |
| • high-risk race/ethnicity (e.g., African American, Latino, Native American, Asian American, Pacific Islander) |
| • women who delivered a baby weighing >9 lb or were diagnosed with GDM |
| • hypertension (≥140/90 mmHg or on therapy for hypertension) |
| • HDL cholesterol level <35 mg/dL (0.90 mmol/L) and/or a triglyceride level >250 mg/dL (2.82 mmol/L) |
| • women with polycystic ovary syndrome |
| • A1C ≥5.7%, IGT, or IFG on previous testing |
| • other clinical conditions associated with insulin resistance (e.g., severe obesity, acanthosis nigricans) |
| • history of CVD |
| 2. For all patients, particularly those who are overweight or obese, testing should begin at age 45 years. |
| 3. If results are normal, testing should be repeated at a minimum of 3-year intervals, with consideration of more frequent testing depending on initial results (e.g., those with prediabetes should be tested yearly) and risk status. |
