The Prevalence of Erectile Dysfunction in Type 2 Diabetic and Non-Diabetic Men : A Comparative case control study

Objective: The aim of our study was to estimate the prevalence of erectile dysfunction among Kuwaiti and non-Kuwaiti type 2 diabetic and non-diabetic men attending "Qurain" special clinic and "Surra" family clinic" in the Ahmadi and the capital area, Kuwait. Subjects and Method: Three hundred and fifty men aged 21 - 85 years who visited "Qurain" special clinic in Ahmadi area and "Surra "clinic in the capital area in Kuwait during a period from 18/4/2007 to 5/9/2008 were included in this study. This was an age matched case control study including 175 (50%) type 2DM and 175 (50%) non-diabetic men. The questionnaire (including the International Index of erectile function-5) was administered to all patients. The average score of each item and the total score of 5 items were calculated and compared in each group. x2-test was used for statistical analysis; p-value < 0.05 was considered significant. Results: The mean age for Type 2 DM patient was 48.9 years in "Qurain" clinic and 52.24 years in "Surra" clinic and non-diabetic men with age 49.05 in "Qurain" clinic and 52.8 in "Surra" clinic. There was a statistically significant difference between diabetic and non-diabetic men in respect to the 5 domains of severity (with a P value < 0.001). There was a statistically significant difference between type2DM and non diabetic men with respect to tadalafil intake (p < 0001). Conclusion: The prevalence of erectile dysfunction is high among Kuwaiti and non-Kuwaiti males attending primary health care. It is significantly higher in type 2 DM patient in "Qurain' and "Surra" clinic than in non-diabetic men. The IIEF-5 is helpful in an initial evaluation of male patients with erectile dysfunction.
