Takeaway

  • Screening for erectile dysfunction (ED) can be used to improve the accuracy of type 2 diabetes (T2D) screening.

Why this matters

  • "[T2D] has been extensively associated with erectile dysfunction, with a global prevalence of 50% in men with [T2D]," say researchers. "[H]owever, there have been few studies on how this seemingly important associated factor can be used to improve [T2D] screening."

Study design

  • Researchers screened patients (n=799; mean age, 48.6±10.7 years) for ED by asking the question, "Have you had difficulties obtaining an erection in the last 6 months?"
  • They determined T2D risk scores for each patient, using the Finnish Diabetes Risk Score (FINDRISC), Latin American (LA)-FINDRISC, American Diabetes Association (ADA) score, and Peruvian Risk Score.
  • They then assessed patient diabetes status based on an oral glucose tolerance test and self-reported physician diagnosis.
  • Funding: Wellcome Trust.

Key results

  • ED was strongly associated with T2D in regression models, whether unadjusted (prevalence ratio, 3.82) or adjusted (prevalence ratio, 2.71).
  • All risk scores except ADA had better diagnostic accuracy when applied to patients with ED.

Limitations

  • The study assessed ED status based on 1 question instead of a validated questionnaire.
