HIV seroprevalence and associated risk factors in men who have sex with men in the Villavicencio city, Colombia, 2005
Background: Given the characteristics of men who have sex with men (MSM), this is considered one of the most vulnerable groups in Colombia. This transversal descriptive study was designed with the objective to establish the seroprevalence and associated risk factors to HIV-1, Syphilis and VHB in MSM in Villavicencio City, Colombia, following national guidelines on second generation public health surveillance for HIV and STIs.
Methods: A, specific, validated, behaviour surveillance survey was applied to MSM. Test for HIV (ELISA), VHB (HBAsg) and Syphilis (RPR) and their respective confirmatory tests (W.B., Anti - core y FTA-abs) were taken. Sample sizes were calculated using Statcalc and the information processing was analyzed using Epiinfo.
Results: 52 MSM participated; the media age was 27.9 years old. The seroprevalence found was VIH (25%) (IC:95%: 14-38,9%), Sífilis (7,7%) (IC:95%: 2,1-18,5%) and VHB (1,9%) (IC:95%: 0,0-10,3%); From an epidemiological perspective the prevalence and its associated risks are described for this group. Socio-cultural and political vulnerability, discrimination, machismo, unprotected sex, bisexual behaviour, un-sustained condom use, frequent alcohol use and history of sexual abuse were identified as HIV/STIs associated risk factors.
Conclusions: These results contribute to determine the health needs and more specifically sexual health needs of MSM and their vulnerability to HIV, VHB and Syphilis. This information should be used in the promotion, prevention and care strategies for this population.
