This study considers policy alternatives aimed at reducing sexual risk-taking among men who have sex with men (MSM) in Vancouver. Using both quantitative data and qualitative research, the study identifies factors that influence sexual risk-taking and the relevant policy instruments for intervention. Using data collected in the 2007 Sex Now Survey, a statistical analysis demonstrates that MSM under 30, those with more than five sexual partners and those who believe that antiretroviral treatment has made sex less worrisome have a higher probability of risk-taking, on average. Epidemic knowledge is found to decrease the probability of risktaking, on average. Findings are used to determine the effectiveness of four policy alternatives, which are then ranked according to cost, equity and ease of implementation. Policy recommendations include: (i) the creation of a Research and Health Promotion Centre and (ii) the formation of an inter-agency working group
