AB130. The relationship between dietary intake and endothelial function among vasculogenic erectile dysfunction population

Objective: The aim of present study was to evaluate the association between dietary intake and endothelial function among the erectile dysfunction males attending for clinics.

Methods: We performed a prospective study between March 2014 and June 2014 at the urology OPD in Tri-Service General Hospital. Forty-four patients were enrolled and filled out the IIEF (the international index of erectile function) questionnaire. The 24-hour dietary recall and peripheral arterial tonometry (PAT) were conducted. Augmentation index (AI%) and reactive hyperemia index (RHI%) were represented systematic arterial stiffness and endothelial-dependent vasodilation respectively.

Results: Our final results showed that vegetable intake which portions adjusted by 1,000 kcal of, were negatively related to IIEF score. A negative correlation was noted between AI% and IIEF score, and the association between AI% and exchange of whole grain intake was also observed. In addition, RHI% was marked associated with intake of poly-unsaturated fatty acid.

Conclusions: Dietary intakes were related to endothelial function among ED patients, especially whole grain products and the vegetables. Detailed the mechanism of pathogenesis should be examined in future larger study.
