Which statement best reflects USPSTF guidance on screening for prediabetes and type 2 diabetes?

• A. Screen all adults aged 18-34 regardless of weight status.
• B. Screen only if there are symptoms of diabetes.
• C. Screen only those with a family history of diabetes.
• D. Screen adults aged 35-70 who are overweight or obese; offer or refer patients with prediabetes to effective preventive interventions.

Answer: (D)

Screening focuses on people at higher risk for abnormal glucose: adults aged 35–70 who are overweight or obese. This approach recognizes that prediabetes and type 2 diabetes often develop silently, so targeted screening in this risk group helps identify those who can benefit from early intervention. When prediabetes is detected, offering or referring to effective preventive interventions—most notably intensive lifestyle changes that have been shown to prevent or delay diabetes onset—is recommended to reduce progression and improve health outcomes. The other statements don’t fit because screening all young adults regardless of weight ignores the risk pattern USPSTF targets, screening only with symptoms misses many asymptomatic cases, and screening based solely on family history would miss individuals without that history who are still at high risk.
