HIV prevalence, sociodemographic characteristics, and sexual behaviors among transwomen in Mexico City.

Objective: To present results from HIV testing, knowledge of HIV status and socioeconomic factors associated with the probability of having a HIV positive result among transwomen (TW) in Mexico.

Materials And Methods: In 2012, we conducted an HIV seroprevalence survey to 585 TW in Mexico City in three strata: gathering places, the Condesa HIV Clinic and in four detention centers. We estimated the prevalence of HIV in each strata and applied a probit model to the overall sample to analyze factors associated with the probability of a HIV positive result.

Results: The prevalence of HIV was 19.8% in meeting places; 31.9% in detention centers and 64% among the participants of the clinic. Age, low education and number of sexual partners was positively associated with HIV.

Conclusions: Results from the study provide relevant information to design HIV prevention interventions tailored to the needs of the TW population.
