Abstract: (1) Background: Condomless anal sex and substance use are associated with STI risk among gay, bisexual, and other men who have sex with men (gbMSM). Our first study objective was to describe event-level sexual risk and substance use trends among gbMSM. Our second study objective was to describe substances associated with event-level sexual risk. (2) Methods: Data come from the Momentum Health Study in Vancouver, British Columbia and participants were recruited from 2012–2015, with follow-up until 2018. Stratified by self-reported HIV status, we used generalized estimating equations to assess trends of sexual event-level substance use and assessed interactions between substance use and time period on event-level higher risk sex defined as condomless anal sex with an HIV serodifferent or unknown status partner. (3) Results: Event-level higher risk anal sex increased across the study period among HIV-negative/unknown (baseline prevalence: 13% vs. study end prevalence: 29%) and HIV-positive gbMSM (baseline prevalence: 16% vs. study end prevalence: 38%). Among HIV-negative/unknown gbMSM, event-level erectile drug use increased, while alcohol use decreased over the study period. Overall, interactions between substance use and time on higher risk anal sex were not statistically significant, regardless of serostatus. However, we found a number of time-specific significant interactions for erectile drugs, poppers, Gamma-hydroxybutyrate (GHB), crystal meth hetamine and ecstasy/MDMA use among HIV-negative/unknown gbMSM. (4) Conclusion: Significant differences in substance use trends and associated risks exist and are varied among gbMSM by serostatus. These findings provide a more comprehensive understanding of the effects of event-level substance use on sexual risk through longitudinal follow-up of nearly six years.

Abstract: Quantitative studies of gay and bisexual men have often reduced relational experiences to single dimensions and explored linkages with sexual risk behaviours. We sought to document the intersection of multiple relationship dimensions among 218 HIV-positive and 556 HIV-negative gay and bisexual men, and estimate associations with love and affection as well as various health and social covariates. We performed latent class analysis of relationships, employing five indicators: relationship status, sexual agreement (monogamous/open), and number of recent sex partners, sex parties, and anonymous sex encounters. We assessed differences in love and affection, and identified covariates using multinomial logistic regression. Two latent classes involved single men: ‘single, less sex partners’ (45% of s le) and ‘single, more sex partners’ (17%), differentiated by number of partners (52% vs. 92% of each class had ≥5 partners, respectively), party sex (3% vs. 57%), and anonymous sex (2% vs. 58%). Three involved regular partners: ‘monogamish’ (15%) (78% were monogamous yet 50% reported ≥1 recent sex partner) ‘open, less sex partners’ (15%) (100% open, 43% ≥5 partners, 10% party sex, 4% anonymous sex) and ‘open, more sex partners’ (9%) (96% open, 92% ≥5 partners, 47% party sex, 69% anonymous sex). Love and affection were common across classes, although more prevalent among partnered (85–91%) versus single (48–51%) men. Relative to ‘single/less partners,’ the study demonstrated that higher sexual sensation seeking scores were associated with membership in every class except ‘monogamish’ erectile dysfunction drug use was associated with being in the ‘more partners’ (single and open) classes anxiety and older age were associated with the ‘open/less partners’ class and loneliness was associated with reduced odds of membership in all three partnered classes. We uncovered considerable relational ersity among gay and bisexual men and complex associations with love and wellbeing. Findings are relevant for sex researchers, educators, and therapists.
