[Seroprevalence of various viruses and sociodemographic characteristics of women seeking HIV screening]. / Seroprevalencias a diversos virus y características sociodemográficas en mujeres que buscan detectarse VIH.

ABSTRACT

OBJECTIVES: To study the seroprevalence of syphilis, herpes simplex-2, hepatitis B and HIV, and main sociodemographic characteristics and sexual behavior in women seeking testing for human immunodeficiency virus (HIV) in Mexico City. METHODOLOGY: A self-applied questionnaire was used in 454 women; and a blood sample was taken for the detection of markers for syphilis, herpes simplex virus-2 (HSV-2)), antibodies against core and surface antigens for hepatitis B virus (HBV), and ELISA and Western blot for HIV. RESULTS: Seroprevalences for antibodies against T. pallidum, HSV-2, HBV and HIV were 4.6%, 29.3%, 3.5% and 4.0%, respectively. Forty-six percent of the women were 20 to 29 years old; 70% reported complete junior high school or higher education level; 75% were sexually active; 56% reported at least one stable male sexual partner, 17% reported at least one occasional male sexual partner in the last three months, and 60% had had at least one sexual relation in the last three months; of these, only 18% (n = 82) reported the use of a condom as a preventive measure. Almost 30% of the HIV positive women had a history of blood transfusion, while less than 10% of the HIV negative women had received a transfusion. In addition, 10.6% said that one of their sexual partners was infected with HIV or had AIDS. CONCLUSIONS: Risks of HIV/STD transmission for this group of self-selected women were linked to blood transfusion, low education and, most important, the risk from male sexual partners who were HIV seropositive. It is expected that these results will contribute to the improvement and development of strategies for the control and prevention of STD among this population group, as well as the general population in Mexico.
