Background This presentation has 2 primary objectives. First, to describe sociodemographic, psychosocial, sociosexual, environnemental and health predictors of a HIV seroconversion risk behaviour, unprotected anal intercourse with HIV-positive or HIV-unknown casual partners (UAI(+/?)), among HIV-negative MSM who live in Quebec and use Internet to find sexual partners. Second, to analyse factors associated to those predictors.
Method We use data from Net Gay Baromètre 2008, a online quantitative survey which took place on Quebec’ dating websites from December 2007 to May 2008. 3718 MSM participated in this survey of whom 1794 were HIV-negative. Bivariate analysis (χ2; t test) and hierarchical regression were performed with SPSS v0.16.0 for Macintosch.
Results 14.7% of HIV-negative respondents have declared an UAI(+/?) in the past 12 months. Multivariate analysis show that homosexual identity, number of casual partners, marginal sexual practices, drug use, engagement in a couple relationship and history of a STI in the past 12 months were significant predictors associated with UAI(+/?) among those respondents. Bivariate analysis show that those predictors were more often declared among respondents who live in Montreal region, are seeking sensations, are seeking partners in sex venues and are regularly seeking partners on dating websites.
Conclusions This group of predictors and associated factors shows various sexual scenarios. Those sexual scenarios seem to be more frequent in certain spaces like Internet, which influence the management of sexual risks. Initiatives to prevent HIV seroconversion adapted to the reality of MSM who live in Quebec and use Internet to find sexual partners are proposed.
