Abstract

Pre-exposure prophylaxis (PrEP) is an efficacious strategy for reducing the incidence of HIV infection. It has been available in Spain since 2019. We aim to report on awareness, knowledge of, intention to use, and eligibility for PrEP and related factors among participants in the European Men-Who-Have-Sex-With-Men Internet Survey (EMIS-2017) in Spain. We used Spanish data from EMIS-2017, a cross-sectional study performed among gay, bisexual, and other men who have sex with mean (GBMSM) from 50 countries. We found that 65.3% of the 10,634 participants were aware of PrEP, some 30.1% of those HIV-negative and ≥ 18 years were eligible and 52.7% of those eligible intended to use it. Regarding knowledge about PrEP, only 15.4% of the participants knew 3 statement with true information about that PrEP meant. Older age, being born in Western Europe (WE) and greater outness were associated with greater awareness. Older age, being born in Latin America or Caribbean or WE, sex work, and living in a large city were associated with greater eligibility. A greater degree of outness was associated with reduced intention to use. Our study point to possible barriers in the implementation of PrEP in Spain and similar countries.

Factors associated with low levels of HIV testing among young men who have sex with men (MSM) participating in EMIS-2017 in Spain

Sex Transm Infect 2022; 98(7):518-524. doi: 10.1136/sextrans-2021-055193.

Authors: Nuria Gallego, Asuncion Diaz, Cinta Folch, Sebastian Meyer, Maria Vazquez, Jordi Casabona, Victoria Hernando 

Abstract

Purpose: The European Men who have sex with men Internet Survey looked over the characteristics and needs of men who have sex with men (MSM) across Europe. Our objective was to estimate the prevalence of HIV testing and its associated factors among MSM younger than 25 years old participating in the EMIS-2017 in Spain.

Methods: Multivariable regression model was used to compare those who had been tested for HIV within the last 12 months and those that had not.

Results: Of 2313 participants, 1070 (46.3%) had been tested for HIV in the past 12 months. Increased age (age 19-21 years, aOR=3.38 (95% CI 2.57 to 4.44); age 22-24 years, aOR=5.26 (4.06 to 6.92) compared with age 16-18 years); being migrant (Latin America: aOR=1.34 (0.98 to 1.84); Europe, North America and Mediterranean countries (aOR=1.56 (0.98 to 2.51) compared with those from Spain); living more openly with one’s sexuality (out to some people (aOR=1.53 (1.19 to 1.96)); out to all or almost all people (aOR=2.24 (1.75 to 2.87) compared with those out to none or a few people); having had one condomless steady partners in the las year ((aOR=1.59 (1.26 to 2.02)); having had condomless non-steady partners in the last year (one: aOR=1.76 (1.35 to 2.29)); two or more partners: aOR=2.37 (1.84 to 3.04)); and having practised sex work in the past year (aOR=1.52 (1.07 to 2.13)) were associated with increased odds of HIV testing. Living in a smaller city was associated with less likelihood of HIV testing (<1 00 000 inhabitants: aOR=0.51 (95% CI 0.41 to 0.64); 100 000-500 000: aOR=0.68 (95% CI 0.54 to 0.86) compared with more than 500 000).

Conclusion: Young MSM showed low HIV testing rate. Future programming specifically targeting this population, especially those middle adolescents, living in a medium-small city and having less ‘outness’, can help increase HIV testing and prevent access barriers.

Influence of Internalised Homonegativity on sexual risk behaviour of men who have sex with men in Spain

Sexuality & Culture, published online first 27 November 2021 (doi: 10.1007/s12119-021-09925-7).

Authors: İbrahim Sönmez, Cinta Folch, Nicolas Lorente, Rigmor C. Berg, Natalie Thurlby & Axel J. Schmidt

Abstract

In a sample of men who have sex with men (MSM) (N = 3436) in Spain who bear intrinsic HIV risk, we investigated how internalised homonegativity (IH) is associated with the number of non-steady male partners with condomless intercourse (as a proxy of sexual risk behaviour). Using structural equation modelling (SEM), we examined the relationship between IH and sexual risk behaviour, and mediating effects of HIV/PrEP knowledge and substance use during sex on this relationship. We found no direct association between IH and sexual risk behaviour, nor did IH influence substance use during sex. In line with our hypothesis, association between IH and sexual risk behaviour was significant when mediated by HIV/PrEP knowledge. We found that as IH increased, sexual risk behaviour decreased, because higher IH was associated with lower HIV/PrEP knowledge while higher HIV/PrEP knowledge was associated with increased non-condom use with non-steady partners. Substance use during sex was significantly associated with sexual risk behaviour. Our results emphasize the continuing importance of prevention strategies focused on behavioural changes and community level interventions, especially targeting substance use.

Awareness of, willingness to take PrEP and its actual use among Belgian MSM at high risk of HIV infection: secondary analysis of the Belgian European MSM internet survey

AIDS and Behavior, published online first 24 November 2021 (doi: 10.1007/s10461-021-03526-z).

Authors: Veerle Buffel, Thijs Reyniers, Caroline Masquillier, Estrelle Thunissen, Christiana Nöstlinger, Marie Laga, Edwin Wouters, Wim Vanden Berghe, Jessika Deblonde, Bea Vuylsteke

Abstract

We examined PrEP awareness, willingness to take it and early PrEP use among men who have sex with men (MSM) at increased risk of HIV acquisition in Belgium. This analysis of the Belgian EMIS online data of 2017–2018 adopts a cascade approach, with the following steps quantified as conditional probabilities: being eligible for, aware of, willing to take PrEP, and PrEP use. One out of three MSM was eligible to use PrEP according to the operationalized Belgian reimbursement criteria. PrEP awareness was lower among socioeconomically vulnerable MSM, MSM living outside large cities, MSM who were less open about their sexuality and those who did not identify as gay or homosexual. A lack of PrEP knowledge, a higher self-efficacy regarding safe sex, having a steady partner and reporting more symptoms of depression were related to unwillingness to use PrEP. Among those willing to take PrEP, less than one third were actually using PrEP. Not using PrEP was associated with living in small cities and experiencing financial problems.

Changes in the prevalence of self-reported sexually transmitted bacterial infections from 2010 and 2017 in two large European samples of men having sex with men – is it time to re-evaluate STI-screening as a control strategy?

PLoS ONE, 2021; 16(3): e0248582 (doi: 10.1371/journal.pone.0248582).

Authors: Ulrich Marcus, Massimo Mirandola, Susanne B Schink, Lorenzo Gios, Axel J Schmidt

Abstract

Background/Objectives: Many European countries reported increased numbers of syphilis, gonorrhoea and chlamydia diagnoses among men who have sex with men (MSM) in recent years. Behaviour changes and increased testing are thought to drive these increases.

Methods: In 2010 and 2017, two large online surveys for MSM in Europe (EMIS-2010, EMIS-2017) collected self-reported data on STI diagnoses in the previous 12 months, diagnostic procedures, STI symptoms when testing, number of sexual partners, and sexual behaviours such as condom use during the last intercourse with a non-steady partner in 46 European countries. Multivariate regression models were used to analyse factors associated with diagnoses of syphilis, gonorrhoea/chlamydia, and respective diagnoses classified as symptomatic and asymptomatic. If applicable, they included country-level screening rates.

Results: Questions on STI diagnoses and sexual behaviours were answered by 156,018 (2010) and 125,837 (2017) participants. Between 2010 and 2017, overall diagnoses with gonorrhoea/chlamydia and syphilis increased by 76% and 83% across countries. Increases were more pronounced for asymptomatic compared to symptomatic infections. The proportion of respondents screened and the frequency of screening grew considerably. Condomless anal intercourse with the last non-steady partner rose by 62%; self-reported partner numbers grew. Increased syphilis diagnoses were largely explained by behavioural changes (including more frequent screening). Gonorrhoea/chlamydia increases were mainly explained by more screening and a change in testing performance. A country variable representing the proportion of men screened for asymptomatic infection was positively associated with reporting symptomatic gonorrhoea/chlamydia, but not syphilis.

Discussion/Conclusion: The positive association of country-level screening rates with the proportion of symptomatic infections with gonorrhoea/chlamydia may indicate a paradoxical effect of screening on incidence of symptomatic infections. Treatment of asymptomatic men might render them more susceptible to new infections, while spontaneous clearance may result in reduced susceptibility. Before expanding screening programmes, evidence of the effects of screening and treatment is warranted.

Chemsex and diagnoses of syphilis, gonorrhoea and chlamydia among men who have sex with men in the UK: a multivariable prediction model using causal inference methodology

Sexually Transmitted Infections, 2021; 97:282-289. (doi: 10.1136/sextrans-2020-054629).

Authors: Louis MacGregor, Manik Kohli, Katharine J Looker, Ford Hickson, Peter Weatherburn, Axel J Schmidt, Katy M Turner

Abstract

Introduction: In the last decade diagnoses of most STIs have risen among men who have sex with men (MSM). Although a significant proportion of this is likely due to increased STI screening, understanding the role of behavioural drivers remains critical. We measure the associations between stimulant use to enhance and prolong sexual experiences (chemsex) and bacterial STI diagnoses in UK MSM, individually considering HIV-diagnosed MSM, pre-exposure prophylaxis (PrEP) users and other MSM.

Methods: We used the UK 2017-2018 European MSM Internet Survey data (n=9375). We constructed causal inference models using multivariable logistic regression, calculating adjusted OR (aOR) and 95% CI of the associations between participation in recent (≤12 months) exclusively dyadic or multipartner chemsex versus no chemsex and recent self-reported diagnoses of syphilis, gonorrhoea and chlamydia.

Results: Among MSM with an HIV diagnosis, 25% of users indicated recent multipartner chemsex, vs 28% of PrEP users and 5% of other MSM. Adjusting for age, ethnicity, UK birth, cis-trans status, sexual identity, education, settlement size and relationship status, participation in recent multipartner chemsex versus no chemsex was associated with greater odds of recent syphilis, gonorrhoea and chlamydia diagnosis. aORs for recent syphilis, gonorrhoea and chlamydia diagnoses were 2.6 (95% CI 1.7 to 4.1), 3.9 (95% CI 2.6 to 5.8) and 2.9 (95% CI 1.9 to 4.3), respectively, in HIV-diagnosed MSM; 1.9 (95% CI 1.1 to 3.3), 2.9 (95% CI 2.0 to 4.2) and 1.9 (95% CI 1.3 to 2.8), respectively, in PrEP users; and 4.0 (95% CI 2.3 to 6.9), 2.7 (95% CI 1.9 to 3.8) and 2.3 (95% CI 1.6 to 3.4), respectively, in other MSM. Conversely, exclusively dyadic chemsex had no significant associations with bacterial STI diagnoses among HIV-diagnosed MSM, only gonorrhoea (aOR 2.4, 95% CI 1.2 to 4.7) among PrEP users and syphilis (aOR 2.8, 95% CI 1.4 to 5.6) among other MSM.

Discussion: Multipartner chemsex may drive the association between chemsex and bacterial STI diagnoses and thus should be the focus of future tailored chemsex interventions. Additionally, PrEP acceptability among MSM and particularly chemsex participants has generated an emergent group suitable for such interventions.

An update on the performance of STI services for gay and bisexual men across European cities: results from the 2017 European MSM Internet Survey

Sexually Transmitted Infections, 2021; 97: 201-208 (doi: 10.1136/sextrans-2020-054681).

Abstract

Objectives: Rectal STIs compromise health and are common in men who have sex with men (MSM). However, the European-MSM-Internet-Survey (EMIS-2010) showed that in 2010, the prevalence of anal swabbing during STI screening by MSM varied widely across 40 European cities. In this paper, we replicate a variety of measures of STI testing performance using 2017-18 data and extending the geographic spread of the analysis.

Methods: Data were analysed from the EMIS-2017, a 33-language online sexual health survey accessible from 18 October 2017 to 31 January 2018. We focus on a subsample of 38 439 respondents living in the same 40 European cities we reported on in 2010. For a broader perspective, we also included an additional 65 cities in the analysis (combined n=56 661). We compared the prevalence of STI screening in MSM and disclosure of same-sex sexual contacts to the healthcare provider. We applied multivariable logistic regression models to compare the odds of MSM receiving each of four diagnostic procedures, including anal swabbing in the previous 12 months, controlling for age, HIV diagnosis, pre-exposure prophylaxis use and number of sexual partners.

Results: In 2017, across 40 European cities, the proportion of respondents screened for STIs ranged from under 19% in Belgrade to over 59% in London. At an individual level, in comparison to London, the adjusted OR (AOR) of having received anal swabbing ranged from 0.03 in Belgrade, Bucharest and Istanbul to 0.80 in Oslo, with little evidence for a difference in Amsterdam and Dublin. Since 2010, most cities in West and South-west Europe have substantially narrowed their performance gap with London, but some in East and South-east Europe have seen the gap increase.

Conclusions: Although comprehensive STI screening in MSM has expanded across many European cities, the low prevalence of anal swabbing indicates that rectal STIs continue to be underdiagnosed, particularly in East/South-east Europe.

A community-friendly summary was written by Roger Pebody and published on 3 Dec 2020 in nam/aidsmap: Rectal STIs are still not being diagnosed in many European cities, due to inadequate screening

Potential alcohol use disorder among MSM in Ireland – Findings from the European MSM internet survey (EMIS 2017)

Drug and Alcohol Dependence, 2021; 223: 108698 (doi: 10.1016/j.drugalcdep.2021.108698).

Authors: Fionn P. Daly, Kate O’Donnell, Martin P. Davoren, Chris Noone, Peter Weatherburn, Mick Quinlan, Bill Foley, Derval Igoe, Peter M. Barrett

Abstract

Background: Alcohol consumption is a major public health concern in Ireland. Alcohol use disorder (AUD) disproportionately affects men who have sex with men (MSM). However, little is known about the prevalence of AUD in this group in Ireland specifically, and the characteristics of MSM who may struggle with this.

Methods: The European MSM Internet Survey 2017 was an online, self-completed, anonymous questionnaire among MSM in Ireland. Standardised questions were used to explore a variety of topics. The validated CAGE-4 questionnaire was used to screen for potential AUD, defined as a CAGE-4 score of ≥2 out of 4. Multivariable-adjusted logistic regression analysis was used to identify factors associated with potential AUD.

Results: In total, 1793 MSM met inclusion criteria. 31 % screened positive for AUD. We observed higher odds of possible AUD among MSM who were bisexual (vs. gay/homosexual) (aOR 1.48 95 %CI 1.01–2.18), native to Ireland (vs. non-native) (aOR 1.49 95 %CI 1.12–1.96), unemployed (vs. employed) (aOR 1.80 95 %CI 1.02–3.16), had used illicit drugs in the previous year (vs. none) (cannabis only, aOR 1.74 95 %CI 1.14–2.63) (other illicit drugs, aOR 2.28 95 %CI 1.67–3.09), reported anxiety/depression (vs. none) (aOR 1.73 95 %CI 1.12–2.66), and MSM who experienced homophobic abuse (vs. never) (aOR 1.55 95 %CI 1.09–2.22). Student MSM were less likely to screen positive for AUD (vs. employed) (aOR 0.65 95 %CI 0.46−0.93).

Conclusions: The prevalence of AUD appears to be higher in the MSM population compared to the general male population in Ireland. Targeted interventions may be warranted to reduce the burden of AUD among MSM.

Structural stigma and sexual minority men’s depression and suicidality: A multilevel examination of mechanisms and mobility across 48 countries

Journal of Abnormal Psychology, 2021; 130(7):713-726 (doi: 10.1037/abn0000693)

Authors: John E Pachankis, Mark L Hatzenbuehler, Richard Bränström, Axel J Schmidt, Rigmor C Berg, Kai Jonas, Michal Pitoňák, Sladjana Baros, Peter Weatherburn

Abstract

Sexual minority men are at greater risk of depression and suicidality than heterosexuals. Stigma, the most frequently hypothesized risk factor for this disparity, operates across socioecological levels-structural (eg. laws), interpersonal (eg. discrimination), and individual (eg. self-stigma). Although the literature on stigma and mental health has focused on interpersonal and individual forms of stigma, emerging research has shown that structural stigma is also associated with adverse mental health outcomes. However, there is limited data on whether changes in structural stigma, such as when a stigmatized person moves to a lower stigma context, affect mental health, and on the mechanisms underlying this association. To address these questions, we use data from the 2017/18 European Men-who-have-sex-with-men Internet Survey (n = 123,428), which assessed mental health (ie. Patient Health Questionnaire) and psychosocial mediators (ie. sexual orientation concealment, internalized homonegativity, and social isolation). We linked these data to an objective indicator of structural stigma related to sexual orientation-including 15 laws and policies as well as aggregated social attitudes-in respondents’ countries of origin (N = 178) and receiving countries (N = 48). Among respondents who still live in their country of birth (N = 106,883), structural stigma was related to depression and suicidality via internalized homonegativity and social isolation. Among respondents who moved from higher-to-lower structural stigma countries (n = 11,831), longer exposure to the lower structural stigma environments of their receiving countries was associated with a significantly: 1) lower risk of depression and suicidality; 2) lower odds of concealment, internalized homonegativity, and social isolation; and 3) smaller indirect effect of structural stigma on mental health through these mediators. This study provides additional evidence that stigma is a sociocultural determinant of mental health.
