Association of Trichomonas vaginalis with sociodemographic factors and other STDs among female inmates in Lisbon.
A study on STDs was conducted among 211 female inmates in a prison in Lisbon, Portugal, in order to establish possible associations between Trichomonas vaginalis infection, sociodemographic factors and other STDs. T. vaginalis was found in 31.2% of the women, from whom only 65.1% presented symptoms. It was more frequently isolated in the 20-40 year age group. On univariate analysis there was an association, although not statistically significant, between the existence of T. vaginalis, multiple sexual partners, drug addiction and no condom use. A statistically significant association was found between trichomoniasis, prostitution and other STDs. These were found in 87% of all women. T. vaginalis was detected alone in 23.8% (15/63) of all women with trichomoniasis, while 76.2% (48/63) of them had multiple infections with trichomonas and other STDs. A statistically significant association was present between trichomoniasis and Mycoplasma hominis and infection with Treponema pallidum. This study showed that the prevalence of T. vaginalis is as high as that of multiple infections with other STDs. Therefore, our findings seem to confirm that trichomoniasis serves as a marker for other STDs. Screening for STDs should then be offered to Portuguese inmates, or, at least, these women should be screened for T. vaginalis, as a marker for the other STDs.
