Criteria for testing for diabetes in asymptomatic adult individuals

1.Testing should be considered in all adults who are overweight (BMI ≥25 kg/m2*) 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.In the absence of the above criteria, testing for diabetes should begin at age 45 years.
3.If results are normal, testing should be repeated at least at 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.
  • * At-risk BMI may be lower in some ethnic groups.
