Background: This research is part of the second generation surveillance studies on HIV being carried out in Colombia to establish the characteristics and vulnerability factors of the most affected populations and to guide the policies that will respond to the epidemic.

Methods: This cross sectional prevalence study used the methodology of Respondent Driven Sampling (RDS). A total of 2562 MSM were enrolled from seven cities in the country (average of 300 per city except Bogota with approximately 500 participants). A behavioral survey was linked to HIV presumptive and confirmatory tests. Informed consent was taken to each participant. Men with an HIV positive result were referred for health care to public/ private health services.

Results: HIV Prevalence per city was: Cali 24%; Bogotá 15%; Barranquilla 13.6%; Cucuta 10,9% ; Cartagena 10%; Medellin 9.1% and Pereira 5,6%. Age ranged between 18 and 34 years for 70% of participants in all cities. In four of the seven cities 33,7% to 49,9% MSM consider themselves as bisexuals. 53% to 73% of all the interviewed had their first sexual encounter below the age of 14, mainly with older men. Condom use in the last sexual relation was between 37,5% and 53,8%. 32% to 45% paid for sexual encounters in the last 12 months and 14% to 30% of all participants had an HIV test in the last 12 months. 11% to 32% had ever had an STI, being gonorrhea, condylomas, syphilis and herpes the most reported. 23% to 43% indicated to have perceived discrimination attitudes in the last year.

Conclusions: Common vulnerability factors for HIV infection were: age older than 25 years, low socio-economic level, previous STIs and poor condom use. These results highlight the need to strengthen prevention activities tailored to the characteristics of these groups, increasing condom provision and better access to VCT and sexual health services.
