Asymptomatic patients with sustained (either treated or untreated) BP > 135/80 mm Hg should be screened for type 2 DM.

Testing for prediabetes and diabetes in asymptomatic adults is also indicated for patients who are overweight (body mass index [BMI] ≥ 25 kg/m2; may be lower in at-risk ethnic groups) and who have one or more of the following risk factors:

  • Physical inactivity

  • First-degree relative with diabetes

  • Member of a high-risk ethnic population (eg, African American, Latino, Native American, Asian American, Pacific Islander)

  • Delivered a baby weighing over 9 lb (4.08 kg) or was diagnosed with gestational DM

  • Hypertension (BP ≥ 140/90 mm Hg or on therapy for hypertension)

  • HDL-C level < 35 mg/dL (0.90 mmol/L) and/or a TG level > 250 mg/dL (2.82 mmol/L)

  • Polycystic ovary syndrome

  • IGT or IFG on previous testing

  • Other clinical conditions associated with insulin resistance (eg, severe obesity, acanthosis nigricans)

  • History of cardiovascular disease

Patients younger than age 30 years are not routinely screened for type 2 DM based solely on self-reported dietary concerns.

Patients with type 1 DM since childhood would not be screened for type 2 DM.
