RESUMO
UNLABELLED: We determined the incidence, epidemiology and type of erectile dysfunction, as well as risk factors related to erectile function in a Mexican population. MATERIAL AND METHODS: 452 surveys were applied in direct form, integrated by 38 questions with open answers, dichotomics and multiple to men that accompanied patients that requested medical attention in our clinic and to workers of the Hospital Juárez de México, 18 years or older, with active sexual life, that knew how to read and write. An analytic, prospective and transverse study was performed; obtaining the incidence, frequency of presentation (organic or psychological) of erectile dysfunction and the odds ratio of risk factors observed in the study. RESULTS: The incidence of erectile dysfunction in the population studied was 26.1% (n = 118); 67.8% probably of psychological origin and 32.2% organic. People younger than 40 years had a presentation of 16.45% and for those > or = 40 years was 50%. Factors of risk: > or = 40 years (OR-5.08), Obesity (OR-1.48), started sexual life > or = 18 years (OR-1.17), intercourse < or = 3/week (OR-1.86), monthly income < or = 250 american dollars (OR-4.81), married (OR-1.39) and in free union (OR-1.44), peasants (OR-3.43), bricklayers (OR-2.96), merchants (OR-2.34), using antihypertensive medication (OR-6.18), with diabetes mellitus (OR-4.09). DISCUSSION: The incidence of erectile dysfunction and its psychological origin was higher than that referred in the literature revised; the higher risk factors associated to erectile dysfunction were: age, diabetes mellitus, obesity, and the use of antihypertensive drugs.
