Resum
Objective: To determine the prevalence of ED and associated risk factors among young Mexicans between 18 and 40 years of age. Methods: An observational, cross-sectional, descriptive and analytic study was conducted. Data collection was achieved through a questionnaire. Participants completed the Urologic Health Survey for Men and the International Index of Erectile Function (IIEF-5) questionnaire. The study also included sociodemographic, clinical, and sexual behavior variables. Results: Of the 373 questionnaires filled out, only 160 were answered completely and used for the analysis. The mean age was 25.59 ± 5.45 years. The prevalence of ED was 33.7% (mild 17.5%, mild-to-moderate 8.1%, moderate 6.3%, and severe 1.9%). The mean score for non-ED males was 24.38 ± 0.94 versus 15.41 ± 4.81 in the ED group. Univariate analysis showed a significant difference in the items of age (p < 0.01), having a stable sexual partner (p < 0.01), sleeping with the sexual partner (p < 0.01), sexual orientation (p = 0.04), and the number of sexual intercourse episodes per week (p < 0.01). In the multivariate analysis ‘‘Not having a stable sexual partner’’ remained a significant risk factor (p = 0.027, OR = 2.60 [CI 1.11---6.08]). Conclusions: In our study, young Mexican adults had an ED prevalence of 33.7% and most of the cases were mild (17.5%). Partner availability was important. No organic variables were related to ED.
