Trichomonas vaginalis infection: risk indicators among women attending for routine gynecologic examination.

Objectives: Trichomonas vaginalis is one of the most common agents of sexually transmitted disease, but trichomoniasis is still considered as an infection of minor importance. The aim of this study was to investigate the risk indicators for trichomoniasis in women attending for routine gynecologic examination.

Methods: The study was conducted comparing demographic and behavioral characteristics in two groups of 122 women with T. vaginalis infection and 853 uninfected women.

Results: Univariate analysis showed a significant increase of T. vaginalis infection among women with older age and multiple sexual partners. In multiple logistic regression analysis, the higher number of lifetime partners and older age remained significantly associated with T. vaginalis infection.

Conclusions: This study suggests that T. vaginalis infection might be mainly related to lifestyle risk factors. Therefore, in our opinion, the diagnosis and treatment of this disease should be encouraged on routine gynecologic examination.
