Background: Trans population had been considered historically included in the MSM group (part of them), specially for epidemiological and behavioral research. There is evidence that trans population have higher risk of HIV infection and faces more inequity situations than general MSM population. Considering UNAIDS and other international recommendations about trans population data disaggregation, CENSIDA promoted this survey.
Methods: In 2012, a cross-sectional survey linked to HIV serology rapid test among trans population (transgender, transexual and traviesti), was implemented in meeting places of 7 urban areas from Jalisco, Veracruz and Estado de México. The collected data included general socio-demographic characteristics, risk factors and sexual behaviors. Tested trans population received pre and post counseling, and when the result of the two rapid tests were reactive, the person was considered as HIV sero-reactive.
Results: In total, 420 trans persons were interviewed, of these, 410 accepted the application of two HIV rapid tests. HIV sero-prevalence in trans population of this study was 15.21% (IC95% 7.56% - 28.24%). Self report results indicates that of those non-reactive, 30.4% (27.2-33.7) were not aware of their status, 68.0% (64.6-71.3) self-reported being no reactive, and 1.6% (0.8-3.0) assumed that they were living with HIV. Of those that were sero-reactive 37.7% (17.7-63.0) assumed they were not living with HIV, 23.0% (12.1-39.2) were not aware of their status and 30.9% (19.5-45.3) reported that they were living with HIV.
Conclusions: Observed sero-prevalence of HIV in trans population of meeting places in this study resulted higher than the observed in a sample of 1,110 MSM who accepted two rapid tests in the same cities, 15.21% in trans (IC95% 7.56% - 28.24%) vs 12.16% (IC95% 6.61% - 17.69%) in MSM respectively. These results could support the hypothesis that trans population could be more affected than MSM by the HIV epidemic in Mexico as well as in other regions. Self report results about HIV infection status, shows that trans population testing initiatives must be improved and implemented in order to detect those living with HIV and refer them to health services. Studies in this population must be prioritized and developed in a continuous and permanent way.
