Criteria for testing for diabetes in asymptomatic adult individuals

1. Testing for diabetes should be considered in all individuals at age 45 years and above, particularly in those with a BMI 25 kg/m2*, and, if normal, should be repeated at 3-year intervals. 
2. Testing should be considered at a younger age or be carried out more frequently in individuals who are overweight (BMI 25 kg/m2*) and have additional risk factors:
  • are habitually physically inactive

  • have a first-degree relative with diabetes

  • are members of a high-risk ethnic population (e.g., African American, Latino, Native American, Asian American, Pacific Islander)

  • have delivered a baby weighing >9 lb or have been diagnosed with GDM

  • are hypertensive (140/90 mmHg)

  • have an HDL cholesterol level 35 mg/dl (0.90 mmol/l) and/or a triglyceride level 250 mg/dl (2.82 mmol/l)

  • have PCOS

  • on previous testing, had IGT or IFG

  • have other clinical conditions associated with insulin resistance (e.g. PCOS or acanthosis nigricans)

  • have a history of vascular disease
