Abstract

Background

Gay, bisexual, and other men who have sex with men (gbMSM) report a higher prevalence of drug use in comparison to the general male population. However, in Ireland, there is a paucity of literature regarding the prevalence of drug use and its determinants among gbMSM.

Aims/Objectives

To quantify the prevalence of (i) recreational drug use (RDU) and (ii) sexualised drug use (SDU) among gbMSM in Ireland, and to identify the factors associated with these drug use practices.

Methods

The European MSM Internet Survey (EMIS) 2017 was an online, anonymous, internationally-promoted questionnaire. Two binary outcomes were included in our analyses: (1) RDU and (2) SDU in the previous year. Multivariable-adjusted logistic regression explored factors associated with these outcomes, and all independent covariates were adjusted for one another.

Results

Among gbMSM without HIV (n = 1,898), 40.9% and 13.1% engaged in RDU and SDU in the previous year, respectively. Among diagnosed-positive gbMSM (n = 141), the past-year respective prevalence estimates were 51.8% and 26.2%. Increased odds of RDU were observed among gbMSM who were younger (vs. 40+ years) (18–24 years; AOR 2.96, 95% CI 2.05–4.28, 25–39 years; AOR 1.66, 95% CI 1.27–2.16), lived in Dublin (vs. elsewhere) (AOR 1.47, 95% CI 1.17–1.83), and engaged in condomless anal intercourse (CAI) in the previous year (vs. none) (1–2 partners; AOR 1.79, 95% CI 1.34–2.38, 6+ partners; AOR 1.79, 95% CI 1.18–2.71). Greater odds of SDU were identified among those who lived in Dublin (vs. elsewhere) (AOR 1.50, 95% CI 1.07–2.10), and engaged in CAI (vs. none) (1–2 partners; AOR 3.16, 95% CI 2.05–4.88, 3–5 partners; AOR 2.50, 95% CI 1.47–4.26, and 6+ partners; AOR 3.79, 95% CI 2.23–6.43).

Conclusion

GbMSM report a high prevalence of drug use in Ireland. Targeted interventions, including harm reduction campaigns, may be needed to support healthier drug use choices among this community.

Abstract

Background

Partner notification (PN) after a sexually transmitted infection (STI) diagnosis is being promoted as a means to interrupt transmission chains. We investigated whether Internalised Homonegativity (IH) is associated with PN among men having sex with men (MSM).

Methods

PN, defined as notifying at least one partner after diagnosis of syphilis and gonorrhoea, was queried in two internet-based self-completion surveys conducted between Oct 2017 and May 2018 in 68 countries in Europe, Latin America, Canada, and the Philippines. IH is defined by a man’s level of agreement or disagreement with negative social beliefs about male homosexuality. Covariates included in a multivariate regression model with a random intercept at country level were age, HIV diagnosis, partnership status, sexual self-efficacy, HIV serostatus communication during last sex with a non-steady partner, place where this partner was met, and PN-related socio-historical background of the country of residence. We grouped countries in three areas: North- and Central-Western European countries plus Canada, former socialist countries, and Latin-American/Mediterranean countries plus the Philippines. In each of the three areas individuals were assigned to 4 subgroups based on IH quartiles and PN rates were determined for each subgroup.

Results

PN rates were calculated for 49 countries (excluding countries with less than 10 diagnoses). Mean proportions of MSM notifying their partners were 68.1% and 72.9% after syphilis and gonorrhoea diagnoses, respectively. PN rates were lower in Latin American countries and the Philippines compared to European countries. Within Europe, a North–South divide with lower PN rates in Mediterranean countries was observed. In each of the three regions we mostly observed a stepwise increase of PN rates with decreasing IH.

Regression analysis showed lower IH scores associated with higher PN rates. Higher perceived self-efficacy, living in a partnership, and HIV status communication were positively associated with PN. Men who had met their last partner in a gay social venue were more likely to have notified their partners of a syphilis diagnosis compared to men who had met this partner online. Men with diagnosed HIV were less likely to report PN.

Conclusions

We could demonstrate that IH was associated with PN among MSM across all countries included in our analysis. Reducing cultural homophobia and ensuring inclusive policies may contribute to STI prevention and control.
