Abstract

Background

Sexualized drug use (SDU) to enhance and extend sexual relations may involve risks of substances abuse (intoxication, interactions and overdose) and higher exposure to HIV and other sexually transmitted infections. There are inconsistencies in the methodology and find- ings of previous research on SDU in Latin America (LA), and more studies are required. The purpose of this research was to characterize SDU in gay men and other men who have sex with men from 18 LA countries, and describe the aspects by comparing people who practice and do not practice SDU, at the general and country levels.

Material and methods

Cross-sectional study based on the data collected by LAMIS-2018. Dependent variable was SDU (last 12 months), and the independent variables were: drug use (in any context/in sex- ual context), sociodemographic, socioepidemiological, and psychosocial aspects. A descriptive analysis was carried out, comparing those who practiced and did not practice SDU.

Results

LAMIS-2018 included 64,655 participants, averaging 30 years of age. 13.6% declared hav- ing practiced SDU (6.6% with multiple partners). In the last sexual encounter the most com- monly used drugs were cannabis (9.3%), poppers (6%), and Viagra (5.4%), and in the last encounter with multiple partners, poppers (19.7%), cannabis (17%), and Viagra (13.2%). HIV diagnosis was reported by 27% of people practicing SDU, vs. 14.3% in the other group. Severe anxiety-depression symptoms were more common among people practicing SDU (9.2% vs. 7%), as were the episodes of homophobic intimidation (52.6% vs. 48.2%), insults (34.4% vs. 28.6%), and aggression (4.1% vs. 3.0%).

Conclusion

SDU was reported by a high percentage of people, with a predominance of the use of drugs related to sexual practice, and others for recreational use. Aspects described as the higher proportion of self-reported HIV diagnosis and severe symptoms of anxiety-depression among those who practiced SDU, show that is necessary to implement preventive strate- gies to reduce the harmful impacts that can sometimes result from this practice, including harm reduction policies, promote access to mental health services and support in situations of homophobia and stigma.

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.

Abstract

Despite men-who-have-sex-with-men (MSM) from Latin America (LA) are still a vulnerable population for known health-related conditions and social problems, availability of comparable data across LA countries for assessment and monitoring purposes is limited. The objective of this article is to present the study design and the questionnaire of LAMIS-2018 (Latin America MSM Internet Survey), its recruitment strategy, rates and sources by country, and the lessons learned from its implementation. LAMIS-2018 was a cross-sectional, internet-based survey targeting MSM living in 18 LA countries (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname, Uruguay, and Venezuela) that gathered data about sexual behaviors, HIV/STI and viral hepatitis knowledge, prophylactic use of antiretrovirals, psychosocial health, and access to sexual health services. The survey went online for four months and was available in three languages (Spanish, Portuguese, and Dutch). Promotion was carried out using dating apps, websites, social networks, and by community-based and academic organizations of each participating country directly in gay venues and in their own premises. Overall, 64,655 MSM participated in LAMIS-2018. Dating apps and websites were the most important recruitment source in most countries, except for Honduras, Nicaragua, and Suriname, where community-based organizations recruited most of the participants. Beyond the LAMIS-2018 implementation description, we highlight the feasibility of such a study in this context, based on the collaboration between community-based and academic organizations to obtain a large sample of MSM in the region. LAMIS-2018 data will contribute to identify determinants of risk behaviors and prevention needs of vulnerable MSM populations in each country of the region.
