Abstract

PrEP uptake in the Netherlands is growing but remains at suboptimal levels. Hence, the analysis of hurdles is paramount. Given the initial focus of PrEP provision among men-who-have-sex-with-men (MSM) via a demonstration project that was launched in June 2015, AmPrEP in Amsterdam, and pharmacies in the main urban areas (so called “Randstad”, entailing Amsterdam, Utrecht, Leiden, The Hague and Rotterdam), investigating regional differences is necessary. This study seeks to unravel regional differences jointly with the psycho-social determinants of PrEP uptake. This cross-sectional study included 3232 HIV-negative MSM recruited via the Dutch subsample of the European-MSM-Internet-Survey in late 2017 (EMIS-2017), which aimed to inform interventions for MSM who are highly affected by infections with HIV and other sexually transmitted infections. Prevalence and the standardised prevalence ratio (SPR) of PrEP awareness, intention and uptake were measured on a regional level (Randstad vs. the rest of the country). Multi-level logistic modelling was conducted to identify the association of PrEP uptake with PrEP awareness and intention, socio-demographic, psycho-social determinants and random effects from regional differences. MSM from the Randstad used more PrEP (SPR = 1.4 vs. 0.7) compared to the rest of the country, but there were minor differences for awareness and intention. The regional distinction was estimated to explain 4.6% of the PrEP use variance. We observed a greater influence from PrEP intention (aOR = 4.5, 95% CI 2.0-10.1), while there was limited influence from the awareness of PrEP (aOR = 0.4, 95% CI 0.04-4.4). Lower education (aOR = 0.4, 95% CI 0.2-0.9) was negatively associated with PrEP uptake; however, no significant difference was found between middle (aOR = 1.2, 95% CI 0.7-2.0) and high education. We showed that regional differences-MSM in non-urban regions-and other psycho-social determinants account for lower PrEP uptake. Based on these findings, more fine-tuned PrEP access with a focus on non-urban regions can be implemented, and tailored campaigns increasing intention/use can be conducted among target populations.

Chemsex users in Czechia: EMIS survey

Cent Eur J Public Health. 2022 Jun;30(2):86-92. doi: 10.21101/cejph.a6923.

Authors: Xenie Uholyeva, Michal Pitoňák

Abstract

Objectives: Chemsex is a phenomenon highly relevant to public health concerns. Our primary aim is to describe the Czech chemsex scene regarding substances used, sexual behaviour, mental health, sexual life satisfaction, internalization of homonegative attitudes, and prevalent chemsex patterns.

Methods: The data from the European Men Who Have Sex With Men Internet Survey (EMIS) 2017 were used. The mental health of chemsex users was assessed by the Patient Health Questionnaire 4 (PHQ4), internalized homonegativity was measured using the Short Internalized Homonegativity Scale. A sample of 87 men who have sex with men (MSM) chemsex users and a comparison group of 261 MSM were selected from the total sample of 1,688 respondents. Mann-Whitney and χ2 tests were used to compare groups.

Results: Active chemsex users made up 5% of the sample (87 of 1,688), with an average age of 37 years. Chemsex users were more likely to engage in condomless sex with non-steady partners (χ2 = 46.8, p < 0.001), and had dramatically more STIs, such as HIV (χ2 = 52.9, p < 0.001), HCV (χ2 = 25.9, p < 0.001), and syphilis (χ2 = 41.5, p < 0.001). Chemsex users frequently injected drugs (n = 19, 20%). More than half (n = 48; 55%) of chemsex users had sober sex in the last 4 weeks. Chemsex culture was associated with riskier substance use, both in terms of mode and frequency. The mental health of chemsex users in our sample did not differ significantly from the comparison group (χ2 = 0.2, p < 0.7). Chemsex users did not conceal their sexual identity more often than the comparison group, on the contrary, 69% (n = 59) of them were out to most significant others, compared to 53% (n = 134) in the comparison group (χ2 = 8.8, p < 0.05). In addition, we did not find differences in the degree of internalized homonegativity (χ2 = 0.9, p < 0.4). Chemsex users were clearly and significantly more satisfied with their sex life than the comparison group (Mann-Whitney U test, p < 0.001).

Conclusions: In our sample, chemsex use was not associated with a negative impact on health or wellbeing. Our results suggest that chemsex is not a homogeneous phenomenon. Many different patterns and subcultures exist, some of them are riskier, some safer than others.

Salud psicosocial de la población de gais, bisexuales y otros hombres que tienen sexo con hombres (HSH) en Colombia.

Revista Colombiana de Psiquiatría, S0034745022000592. https://doi.org/10.1016/j.rcp.2022.04.010

Author: Restrepo Pineda, J. E.

Introduction

Psychosocial health is fundamental to the well-being of the human being. In the case of the gay, bisexual and other men who have sex with men (MSM) population, it is affected by discrimination, homophobia, marginalisation and social exclusion.

Methods

A quantitative investigation was designed, which used a virtual survey. Kruskal Wallis tests were performed for the difference in medians between the internalised Index of Homphobia (IH) and various variables; this same test was used for the comorbidity between anxiety and depression.

Results

A sample of 8,208 individuals was obtained, with ages between 18 and 75 years. Between the IH indices and the educational level variable, statistically significant differences are observed in the medians of the different categories. On the other hand, 8.0% of the population presents with moderate levels of comorbidity between anxiety and depression and 4.0%, a severe level.

Discussion

IH decreases as the subjects prepare academically, while the severity of anxiety and depression is greater in those who report complicated affective relationships. People with a diagnosis of HIV present with a greater severity of depressive symptoms.

Conclusions

IH, depression, and anxiety are linked to intersectional discrimination, leading to greater individual and social vulnerability for people who are gay, people who are bisexual, and other men who have sex with men that directly affects their psychosocial health.

Stigmatizing Policies Interact with Mental Health and Sexual Behaviours to Structurally Induce HIV Diagnoses Among European Men Who Have Sex with Men

AIDS Behav 2022; 26(10):3400-3410. doi: 10.1007/s10461-022-03683-9

Authors: Kristefer Stojanovski, Elizabeth J King, K Rivet Amico, Marisa C Eisenberg, Arline T Geronimus, Sladjana Baros, Axel J Schmidt

Abstract

Structural stigma shapes men who have sex with men’s (MSM’s) mental health and sexual behaviours. The aim of this study was to examine how stigmatizing policies interact with downstream anxiety/depression and sexual behaviours to structurally pattern HIV disparities among European MSM. We conducted a secondary data analysis of the European Men-who-have-sex-with-men Internet Survey (EMIS) from 2017. We included a total of 98,600 participants living in 39 European countries. We used the Rainbow Index, a score given to countries based on their sexual and gender minority policies as the predictor of HIV diagnosis. We conducted adjusted random intercept and slope multi-level logistic regressions. In adjusted models, higher Rainbow Index scores was associated with lower predictive probabilities of diagnosed HIV, regardless of the number of condomless intercourse partners. The predictive probability of HIV diagnosis was also lower, regardless of severity of anxiety/depression, where the Rainbow Index score was better. Country-level policies interact with downstream sexual behaviours and anxiety/depression to structurally influence HIV diagnosis among MSM in Europe.

Abstract

Background: To provide empirically based guidance for substituting partner number categories in large MSM surveys with mean numbers of sexual and condomless anal intercourse (CAI) partners in a secondary analysis of survey data.

Methods: We collated data on numbers of sexual and CAI partners reported in a continuous scale (write-in number) in thirteen MSM surveys on sexual health and behaviour across 17 countries. Pooled descriptive statistics for the number of sexual and CAI partners during the last twelve (N = 55,180) and 6 months (N = 31,759) were calculated for two sets of categories commonly used in reporting numbers of sexual partners in sexual behaviour surveys.

Results: The pooled mean number of partners in the previous 12 months for the total sample was 15.8 partners (SD = 36.6), while the median number of partners was 5 (IQR = 2–15). Means for number of partners in the previous 12 months for the first set of categories were: 16.4 for 11–20 partners (SD = 3.3); 27.8 for 21–30 (SD = 2.8); 38.6 for 31–40 (SD = 2.4); 49.6 for 41–50 (SD = 1.5); and 128.2 for ‘more than 50’ (SD = 98.1). Alternative upper cut-offs: 43.4 for ‘more than 10’ (SD = 57.7); 65.3 for ‘more than 20’ (SD = 70.3). Self-reported partner numbers for both time frames consistently exceeded 200 or 300. While there was substantial variation of overall means across surveys, the means for all chosen categories were very similar. Partner numbers above nine mainly clustered at multiples of tens, regardless of the selected time frame. The overall means for CAI partners were lower than those for sexual partners; however, such difference was completely absent from all categories beyond ten sexual and CAI partners.

Conclusions: Clustering of reported partner numbers confirm common MSM sexual behaviour surveys’ questionnaire piloting feedback indicating that responses to numbers of sexual partners beyond 10 are best guesses rather than precise counts, but large partner numbers above typical upper cut-offs are common.

Would eligible gay, bisexual and other men who have sex with men use PrEP? Awareness, knowledge, eligibility and intention to use PrEP among EMIS-2017 participants in Spain

Prev Med 2022; 156:106962. doi: 10.1016/j.ypmed.2022.106962.

Authors: Carlos Iniesta, Cinta Folch, Sebastian Meyer, María Vázquez, Jordi Casabona, Asunción Díaz

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.

Predictors of knowledge of and access to biomedical prevention among MSM and transgender men in Latin America: Results from the Latin American internet survey.

HIV Medicine; 23(7):764–773. doi: 10.1111/hiv.13238

Authors: Avelino-Silva, V. I., Vasconcelos, R., Cerqueira, N. B., Marcus, U., Schmidt, A. J., & Veras, M. A.

Abstract

Introduction

HIV is still a central public health issue in Latin America, disproportionally affecting key populations. Knowledge and access to biomedical prevention strategies, including treatment as prevention (TASP) or undetectable = untransmissible (U=U), pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP), are the first steps to increasing uptake. We used data from the Latin American MSM Internet Survey (LAMIS) to describe knowledge and access to biomedical HIV prevention strategies among gay, bisexual, transgender and other men who have sex with men (MSM) living in 18 Latin American countries.

Methods

We compared LAMIS data across countries and according to age categories using frequencies and percentages. We also used multivariable models to explore whether age, gender identity, sexual identity, steady partnership, HIV status and education were independently associated with outcomes.

Results

In all, 55 924 participants were included. Most were cisgender (99%) and identified as gay/homosexual (77%) or bisexual (17%). Schooling levels were very high, with 89% reporting highest attained education as tertiary level, university or post-graduation. In total, 16% had been previously diagnosed with HIV; of those, rates of undetectable viral load varied from 60% in Venezuela to 83% in Brazil. Overall, 54%, 54% and 52% of participants already knew about PEP, PrEP and U=U, respectively. Participants from Brazil and those aged between 26 and 55 years, living with diagnosed HIV and having a gay/homosexual identity had greater levels of awareness about biomedical prevention strategies.

Conclusions

Our study highlights gaps in HIV prevention campaigns directed to MSM in Latin America resulting in low uptake of biomedical prevention methods.

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.

Keywords: Awareness of and willingness to use PrEP; Cascade approach; Eligibility criteria; Men who have sex with men (MSM); Pre-exposure prophylaxis (PrEP) use.
