BACKGROUND: Studies have revealed high prevalence rates of Trichomonas vaginalis in men and women worldwide. In Brazil, where reporting is not mandatory, the true prevalence rate is unknown. This study determined the prevalence of the parasite in women attending public health units in the city of Uberlândia, Minas Gerais, Brazil, identifying possible risk factors for infection, and also compared three diagnostic techniques for detecting the parasite. METHODS: Samples of vaginal secretions collected from 742 women attending public health units were analyzed by direct wet mount examination, culture and smear test. Epidemiological questionnaires were administered. RESULTS: Of the total of 742 samples analyzed, 19 (2.6%) tested positive for T. vaginalis. The variables significantly associated with infection were: being of black ethnicity, smoking, having knowledge about sexually transmitted diseases and presenting clinical signs. The culture method was considered the gold standard test. CONCLUSIONS: Although there are programs to control other sexually transmitted diseases, there are none for trichomoniasis. The results of this study indicate the presence of T. vaginalis in the female population, and points to the need for more research in Brazil to gain a better understanding of the profile and epidemiology of the parasite.
