Purpose
Elevated blood lipids are considered a risk factor for atherosclerosis, which can lead to erectile dysfunction. This study aimed to explore the relationship between the atherogenic index of plasma (AIP), atherogenic coefficient (AC), Castelli’s risk index-I (CRI-I), Castelli’s risk index-II (CRI-II), and erectile dysfunction.
Methods
Based on the National Health and Nutrition Examination Survey (NHANES) data from 2001–2004, multivariable-adjusted logistic regression models were used to evaluate the association between AIP, AC, CRI-I, and CRI-II with ED. Smooth curve fitting was employed to assess the linear association.
Results
A total of 1806 male participants with complete data were enrolled in the study. In Model 1, those in the highest tertile of AIP had a 49% increased risk of ED compared to the lowest tertile (OR 1.49; 95% CI 1.15–1.91 p = 0.0021). After adjusting for the variables of age, race, education, body mass index, and poverty income ratio (PIR), significant positive correlations were found between ED and AIP, with each 1-unit increase in AIP associated with a 65% increase in the risk of developing ED (OR 1.65; 95% CI 1.03–2.64 p = 0.0361).
Conclusions
AIP is positively associated with the development of ED in US adults. More prospective cohort studies are needed to confirm the link between AIP and ED.
