Association between statin use and erectile dysfunction: Results from the National Health and Nutrition Examination...

This study aimed to examine the association between statin use and the prevalence of erectile dysfunction (ED) among a diverse cohort of American men aged 20 years and older, utilizing data from the National Health and Nutrition Examination Survey for the years 2001 to 2004. The analysis employed Logistic regression was used to assess the relationship between self-reported statin use and ED, adjusting for potential confounders, including age, ethnicity, educational level, smoking habits, diabetes mellitus, body mass index, alcohol consumption, hypertension, and hyperlipidemia. The initial participant pool consisted of 21,161 individuals, which was narrowed down to 3767 eligible subjects after applying the exclusion criteria. ED was evaluated based on the participants' self-assessment of their ability to obtain and maintain an erection sufficient for satisfactory sexual performance. The study identified a statistically significant association between statin use and an increased prevalence of ED, with an odds ratio of 4.66 (95% confidence interval [CI]: 3.74-5.81) in the crude model. After adjustments for demographic, lifestyle, and health factors, the association remained significant, albeit reduced (odds ratio: 1.77, 95% CI: 1.34-2.35). Subgroup analysis highlighted variable correlation levels among different demographic and health-related groups, with age and body mass index identified as potential modifiers of the relationship between statin use and ED. Our findings indicate a positive correlation between statin use and ED prevalence in a representative sample of the American male population. This association, persistent across various subgroups and after adjusting for multiple confounding factors, underscores the need for further research to elucidate the underlying biological mechanisms and inform clinical decision making. The implications of this study suggest the necessity for a balanced approach in prescribing statin, particularly among populations at risk of ED, highlighting the importance of considering potential side effects in managing cardiovascular risk factors.
