Zorluk: OrtaPreventive Care and Screening

An asymptomatic 37-year-old man presents to the outpatient clinic to establish primary care. He feels well and reports no fatigue, polyuria, or changes in vision. His medical history is unremarkable, and he takes no prescription medications. He works as a software engineer and describes his lifestyle as sedentary. He does not smoke or use illicit drugs and consumes alcohol socially. His father was diagnosed with type 2 diabetes mellitus at age 50.

Records indicate he had a normal fasting lipid panel at age 32 and a negative hepatitis C antibody test three years ago.

Vital signs show a blood pressure of 126/80 mm Hg and a heart rate of 72/min. His body mass index is 29 kg/m^2. Physical examination is unremarkable, with no acanthosis nigricans or peripheral edema.

In accordance with current preventive care guidelines, which of the following is the most appropriate screening test to perform today?

  1. Hemoglobin A1cCevap
  2. B
    Serum thyroid-stimulating hormone
  3. C
    Resting electrocardiography
  4. D
    Fecal immunochemical testing
  5. E
    Routine urinalysis

Cevap

Hemoglobin A1c testing should be performed because the patient is between the ages of 35 and 70 and has a BMI classified as overweight, which meets the current USPSTF criteria for diabetes screening.
This patient is a 37-year-old man with a BMI of 29 kg/m^2, which classifies him as overweight. According to the United States Preventive Services Task Force (USPSTF) guidelines (updated in 2021), clinicians should screen for prediabetes and type 2 diabetes in adults aged 35 to 70 years who are overweight or obese. Hemoglobin A1c, fasting plasma glucose, or an oral glucose tolerance test are all acceptable screening modalities. Given his age and BMI, screening is strongly indicated to identify early dysglycemia and initiate appropriate lifestyle or pharmacologic interventions. His family history of diabetes further compounds his risk, though his age and BMI alone are sufficient to trigger the recommendation.

Adım Adım Çözüm

1
Analyze the patient's demographic and clinical risk profile.
The patient is a 37-year-old male with a BMI of 29 kg/m^2, indicating he is overweight.
Identifying age and BMI is critical for accurately applying metabolic screening guidelines.
2
Evaluate the need for type 2 diabetes screening.
The patient qualifies for diabetes screening because he falls within the 35 to 70 age range and has a BMI >= 25 kg/m^2.
The USPSTF recently updated its guidelines to lower the starting age for diabetes screening from 40 to 35 for overweight and obese adults.
3
Rule out other routine screening modalities based on age and lack of symptoms.
Tests such as FIT, TSH, urinalysis, and ECG do not meet the criteria for routine screening in this asymptomatic 37-year-old.
Adhering to evidence-based guidelines prevents overdiagnosis, unnecessary healthcare costs, and potential harms from false positives.
