RESUMEN
This study describes HIV and syphilis bio-behavioral survey conducted among 200 men who have sex with men (MSM) recruited via respondent-driven sampling (RDS) between January 4 and February 1, 2012 in Ulaanbaatar, Mongolia. Participants were administered a structured questionnaire and data were analyzed with RDS-network program in STATA. Of 196 participants who agreed to be tested for HIV and syphilis, 21 (10.7 %; weighted 7.5; 95 % CI: 4.9, 11.4) and 8 (4.1 %; weighted 3.4; 95 % CI: 1.7, 6.7) were positive for HIV and syphilis, respectively. Exposure to HIV prevention programs in the last 12 months was reported by 51.8 % (weighted 33.6; 95 % CI: 27.6, 40.1) of participants. This study found high HIV prevalence and limited uptake of HIV prevention services among MSM in Mongolia. Given the concentrated HIV epidemic among MSM in Mongolia, HIV prevention, treatment and care services should focus on MSM as the population group most affected by HIV.

BACKGROUND: Surveillance studies among female sex workers (FSWs) in Mongolia have found no HIV but high rates of syphilis, ranging from 10.7% in 2002 to 20.8% in 2007. OBJECTIVES: To determine the current prevalence of HIV and syphilis among FSWs, and to identify syphilis risk factors. METHODS: 761 FSWs were recruited by time-location sampling between 2 January and 29 March 2012 in Ulaanbaatar city, Darkhan-Uul, Orkhon, Khuvsgul and Dornod provinces in Mongolia. Participants were administered an anonymous structured survey. Blood samples were tested for HIV and syphilis. Bivariate and multivariate logistic regression analyses were performed to identify factors associated with syphilis. RESULTS: The mean age of participants was 31 (median 30, interquartile range 24-38). HIV knowledge was modest: 41.3% correctly answered all questions. Consistent condom use with clients was reported by 49.1% of participants and exposure to HIV prevention programmes by 50.1%. Although no cases of HIV were found, syphilis prevalence was -27.8% (95% CI 24.3% to 31.7%). In multivariate analyses, variables associated with syphilis were younger age (age >30 years, OR=0.96, 95% CI 0.92 to 0.99) and occurrence of genital ulcer (OR=2.24, 95% CI 1.17 to 4.28). CONCLUSIONS: A syphilis epidemic continues to grow among FSWs in Mongolia. These women are at high risk of HIV transmission if introduced into their sexual networks. With the increase in migration of mining workers in Mongolia, introduction of HIV may be imminent. Efforts to intensify treatment and prevention programmes among FSWs are needed.
