OBJECTIVE: Our objective was to analyze the prevalence and risk factors for erectile dysfunction (ED) in men with diabetes in Italy in a cross-sectional study. RESEARCH DESIGN AND METHODS: Eligible for the study were men aged 20-69 years with a diagnosis of IDDM or NIDDM who were observed on randomly selected days in 178 diabetes centers in Italy. ED was defined as a failure to achieve and maintain an erection sufficient for satisfactory sexual performance. RESULTS: Of the 9,868 diabetic men interviewed, 3,534 (35.8%) reported ED. The prevalence increased with age, from 4.6% in men aged 20-29 to 45.5% in those aged > or =60 years (test for trend, P = 0.0001). After taking into account the confounding role of age, men with NIDDM reported ED less frequently than did men with IDDM (odds ratio OR, 0.7; 95% CI 0.6-0.8). In comparison with men reporting diabetes lasting or =30 cigarettes day. CONCLUSIONS: The study offers a quantitative estimate of the prevalence of ED and of its main risk factors in Italian men with diabetes.
