RESUMO
This study examined the efficacy of an enhanced intervention to reduce sexual risk of HIV/STI and harmful alcohol use among female sex workers in Mongolia. Women (n = 166) were recruited and randomized to either (1) a relationship-based HIV sexual risk reduction intervention; (2) the same sexual risk reduction intervention plus motivational interviewing; or (3) a control condition focused on wellness promotion. At three and six month follow-up, both treatment interventions and the wellness promotion condition were effective in reducing the percentage and the number of unprotected acts of vaginal sex with paying partners in the past 90 days. All three conditions demonstrated efficacy in reducing harmful alcohol use. No significant differences in effects were observed between conditions. Findings suggest that even low impact behavioral interventions can achieve considerable reductions of HIV/STI risk and harmful alcohol use with a highly vulnerable population in a low resourced setting.
