Exploring the association between consumption of different types of beverages and erectile dysfunction in US men: evidence from NHANES 2003-2004 data.

Background: The aim of this study was to examine the relationship between the type/frequency of consuming beverages and ED among men in America.

Methods: We used data on erectile function and the frequency of beverage consumption from the National Health and Nutrition Examination Survey (NHANES) 2003-2004. Associations between ED and beverage consumption were analyzed using univariate and multivariate logistic regression. We also stratified by age and adjusted for potential confounders using propensity score matching (PSM).

Results: After fully adjusting for covariates, logistic regression showed that regular grape juice consumption (≥ 5 times/week) was related to a lower prevalence of ED (OR = 0.21, 95% CI: 0.08-0.54, p = 0.001). Subgroup analyses found that this correlation remained significant for those over 40 years of age (all p < 0.05). After PSM adjustment, the association between grape juice consumption and ED remained statistically significant (OR = 0.12, 95% CI: 0.03-0.44, p = 0.001). Various beverage types, encompassing tomato, orange, apple, pineapple, and lemonade juices, as well as soft drinks, exhibited a correlation with ED in the initial univariate regression analysis.

Conclusions: In men, regular intake of grape juice (≥ 5 times/week) was associated with a lower prevalence of ED, which was particularly significant in men over 40 years of age.
