Introduction: Exercising and &[Prime]eating better&[Prime] are often associated with a myriad of health benefits such as weight loss and increased energy. Numerous studies have examined the potential advantages of low fat and Mediterranean diets, however, the effects of these dietary regimens on erectile function are unknown. We sought to determine the relationship between popular diets and erectile function.
Methods: The National Health and Nutrition Examination Survey (NHANES) database was queried between the years of 2001 and 2004. Men ages 18-80 years who answered the prostate questionnaire and completed the two-day dietary history were included. Diets were categorized as Mediterranean, American Heart Association low fat, AtkinsÂ® (low carbohydrate), or non-restrictive. Multivariate modeling was then used to determine the relationship between each diet and erectile function.
Results: Among the 4941 men who met inclusion criteria, 784 (15.9%) met criteria for a low-fat diet, 1286 (26.0%) Mediterranean diet, and 2( < 0.1%) Atkins diet. Of the entire cohort, 1999 men (48.6%) had some degree of erectile dysfunction. Univariate analysis showed that men with non-restrictive diets were more likely to endorse normal erectile function compared to those adhering to a low-fat or Mediterranean diet (both p < 0.05). Multivariate analysis controlling for age, body mass index (BMI), activity level, diabetes, comorbidities, prostate cancer and testosterone levels demonstrated that men adhering to a Mediterranean or low-fat diet were equally likely to endorse normal erectile function compared to men without dietary restrictions.
Conclusions: In a nationally representative sample, while increasing age and diabetes were negatively associated with erectile function, there was no association between diet and erectile function. Future prospective research is required to corroborate these findings.
