Abstract
Considerable research has examined how involvement in gay-affiliated communities is associated with sexual health behaviours in sexual minority men (i.e., gay, bisexual, and other men who have sex with men), yet findings in this domain are often contradictory and inconclusive. This systematic review aimed to (a) synthesise the related empirical literature, and (b) identify potential factors driving inconsistent findings. Peer-reviewed publications were included if they contained quantitative data and at least one measure of the statistical association between gay community involvement and sexual health behaviour. The search strategy was implemented in six databases and returned 6,409 articles, of which 86 met the inclusion criteria. There was considerable heterogeneity in how gay community involvement was assessed across studies. Although gay community involvement was consistently associated with greater engagement in protective behaviours across studies, the association between gay community involvement and risk behaviours appeared to depend on how gay community involvement was conceptualised and measured (e.g., nightlife involvement vs. political activism). Findings emphasise a need for studies that employ validated measures that reflect the multidimensional nature of gay community involvement, as well as research designs better suited to address the causal effects of community involvement on HIV/STI transmission and prevention.

Insights from STI/HIV prevention research in European men who have sex with men. BMJ Glob Health 2024; 9:e013285.

Abstract
INTRODUCTION Although sexual health has been holistically defined to include sexual satisfaction, it has been largely absent in health services and sexual and reproductive health and rights programmes in many parts of the world. We propose sexual satisfaction as a useful indicator, as one of the proxy measures for sexual health and well-being and as a component of well-being in general. METHODS The Sialon II project is a multicentre biological and behavioural cross-sectional community-based survey implemented across 13 European cities during 2013-2014 among men who have sex with men. Sexual satisfaction was explored using one single item: 'How satisfied are you with your sex life?' A multivariable multilevel logistic random-intercept model was estimated to identify factors associated with reporting positive sexual satisfaction versus negative sexual satisfaction. RESULTS Age, the number of partners and self-reported HIV status were not significantly associated with sexual satisfaction in the multivariate model. Participants reporting an insertive role or reported both an insertive and receptive role during the last anal intercourse were more likely to be sexually satisfied, compared with a receptive role. Participants reporting anal intercourse with a condom were more likely to be satisfied than those declaring no anal intercourse in the last 6 months, but no significant association was found compared with anal intercourse without condom. Knowledge of HIV-serostatus concordance with the last sexual partner was positively correlated with sexual satisfaction. Having had sexual intercourse with non-steady partners only in the last 6 months was negatively correlated. The more positive participants perceived their work/school, parents and friends/acquaintances' attitudes towards gay or bisexual persons, the higher the odds they were satisfied with their sexual life. CONCLUSION Using a single item on sexual satisfaction in a bio-behavioural study, our analysis has shown that it is associated with individual, interpersonal and social/structural factors and has proven its usefulness as a sexual health indicator among men who have sex with men.

Interventions, Barriers, and Facilitators to Address the Sexual Problems of Gay, Bisexual and Other Men Who Have Sex with Men Living with HIV: A Rapid Scoping Review. AIDS Behav 2024; 28:450-472. [PMID: 38296920 DOI: 10.1007/s10461-023-04237-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/28/2023] [Indexed: 02/02/2024]
Abstract
Sexual problems are common among gay, bisexual, and other men who have sex with men (GBM) after diagnosis with HIV. However, these are often overlooked in care and research, where sexual risk reduction and biomedical aspects of sexual health tend to dominate. We conducted a rapid scoping review to investigate which sexual problems of GBM living with HIV are addressed by interventions, and the barriers and facilitators to their implementation. Literature from high-income countries published in English since 2010 was reviewed. Medline, Embase, PsycInfo, and Scopus databases were searched on July 4, 2022. Targeted sexual problems were categorized according to the ten dimensions of Robinson's Sexual Health Model, and barriers and facilitators, according to the five domains of the Consolidated Framework for Implementation Research (CFIR). Interventions focused solely on the dimension of Sexual Health Care/Safer Sex were excluded. Relevant information was extracted from the qualifying documents with NVivo 12 software for content analysis. Fifty-two documents were included, referring to 37 interventions which mainly took place in the United States (n = 29/37; 78%), were group-based (n = 16; 41%), and used counselling techniques (n = 23; 62%; e.g., motivational interviewing, cognitive-behavioral therapy). Their settings were mostly primary care (n = 15; 40%) or community-based (n = 16; 43%). On average, interventions addressed three sexual health dimensions (SD = 2; range: 1-10). The most targeted dimension was Sexual Health Care/Safer Sex (n = 26; 70%), which concerned sexual risk reduction. Next, Challenges (n = 23; 62%), included substance use (n = 7; 19%), sexual compulsivity (n = 6; 16%), sexual abuse (n = 6; 16%), and intimate partner violence (n = 4; 11%). Third was Talking About Sex (n = 22; 59%) which mostly concerned HIV disclosure. About a third of interventions addressed Culture/Sexual identity (n = 14; 38%), Intimacy/Relationships (n = 12; 33%), and Positive sexuality (n = 11; 30%). Finally, few targeted Body Image (n = 4; 11%), Spirituality (n = 3; 8%), Sexual Anatomy Functioning (n = 2; 5%) or Masturbation/Fantasy (n = 1; 3%). Forty-one documents (79%) mentioned implementation barriers or facilitators, particularly about the characteristics of the interventions (41% and 78%, respectively; e.g., cost, excessive duration, acceptability, feasibility) and of the individuals involved (37% and 46%; e.g., perceived stigmatization, provider expertise). The other three CFIR dimensions were less common (5%-17%). The search strategy of this review may not have captured all eligible documents, due to its limit to English-language publications. Overall, most interventions incorporated a focus on Sexual Health Care/Safer Sex, at the expenses of other prevalent sexual problems among GBM living with HIV, such as intimate partner violence (Challenges), erectile dysfunction (Sexual Anatomy Functioning), and Body Image dissatisfaction. These findings suggest they could receive more attention within clinical care and at the community level. They also highlight the importance of cost-effective and acceptable interventions conducted in non-stigmatizing environments, where patients' needs can be met by providers who are adequately trained on sexuality-related topics.

Prevalence and risk factors for transactional sex among Swedish-born and foreign-born MSM in Sweden. BMC Public Health 2022; 22:2412. [PMID: 36550432 PMCID: PMC9774071 DOI: 10.1186/s12889-022-14764-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Accepted: 11/28/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Little is known about transactional sex (TS) (selling and buying sex) among men who have sex with men (MSM) in Sweden, especially among foreign-born MSM. This study aims to assess the prevalence and risk factors of TS (ever and in the previous five years) among MSM living in Sweden and to determine if there is a difference between Swedish-born MSM and foreign-born MSM. METHODS Swedish data from a multicountry online banner survey (EMIS-2017) was used (n = 4443). Multivariable regression analysis was applied to analyse the data. RESULTS The prevalence of ever-selling sex among all MSM participants was 13.2% and 5.9% in the previous five years. Selling sex ever and in the previous five years was higher among foreign-born MSM (16% and 8.4%, respectively) than Swedish-born MSM (12.7% and 5.4%, respectively). Among all participants, younger age (aOR:3.19, 95% CI:1.57-6.45) and really struggling to live on current income (aOR:3.37, 95% CI:2.29-4.96) increased the odds of selling sex. Being foreign-born MSM (aOR:1.33, 95% CI:1.02-1.73) and having had sex with a woman in the previous 12 months increased the odds of selling sex (aOR:1.44, 95% CI:1.00-2.07). The prevalence of ever buying sex among MSM participants in Sweden was 10.8% and 6.7% in the previous five years, with the same trend among foreign-born MSM (11.6% and 6.9%, respectively) and Swedish-born MSM (10.7% and 6.6%, respectively). Higher education and not having a current partner increased the odds of buying sex. Younger age was protective for buying sex (aOR:0.05, 95% CI:0.02-0.14). Among the foreign-born MSM, the length of stay in Sweden decreased the odds of buying sex (aOR: 0.98, 95% CI: 0.96-0.99). CONCLUSIONS The comparatively high prevalence of TS among MSM participants in Sweden, where buying sex is illegal, with a higher prevalence among foreign-born MSM participants, calls for sexual and reproductive health and rights interventions in this population. Increased attention, including HIV prevention programming and education, should be aimed at younger MSM, MSM struggling with their current income, and foreign-born MSM, as they are more likely to report selling sex.

Abstract
BACKGROUND Disclosure of sexual orientation to others (outness) might be associated with sexual and mental health among gay and bisexual men (GBM) attending university. We aimed to characterise outness and investigate factors correlated with outness among GBM attending university in China. METHODS Between September 2018 and March 2019, GBM attending university were recruited in six cities in China. Information on sociodemographic characteristics, outness and sexual behaviours were collected using a self-administered questionnaire. Each participant was tested for HIV/STIs. Correlates of outness were assessed using multivariable logistic regression. RESULTS A total of 400 GBM attending university were recruited, of whom 251 (62.8%) had disclosed their sexual orientation. Men who served as student leaders (adjusted odds ratio [AOR]=2.28, 95% CI: 1.46-3.54) and donated blood (AOR 1.85, 95% CI: 1.05-3.24) were more likely to disclose their sexual orientation, whereas men who had sex with a female (AOR 0.19, 95% CI: 0.05-0.74) and had group sex (AOR 0.52, 95% CI: 0.30-0.89) were less likely to disclose their sexual orientation. Mental health status, HIV/STI infections were not associated with outness. CONCLUSIONS GBM attending university who disclosed their sexual orientation were more likely to be involved with student work and less likely to engage in high-risk sexual behaviours. More attention and education could focus on non-disclosing GBM men attending university through peer education or other ways.

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.

Abstract
CONTEXT Men generally seek healthcare less often than women and, other than traditional gender norms, less is known about the explanation. The aim was to identify knowledge gaps and factors influencing men regarding sexual and reproductive healthcare (SRHC) in the Nordic countries. METHODS We searched PubMed and SveMed+ for peer-reviewed articles published between January 2010 and May 2020. The analyses identified factors influencing men's experiences of and access to SRHC. RESULTS The majority of the 68 articles included focused on pregnancy, birth, infertility and sexually transmitted infections including HIV. During pregnancy and childbirth, men were treated as accompanying partners rather than individuals with their own needs. The knowledge and attitudes of healthcare providers were crucial for their ability to provide SRHC and for the experiences of men. Organisational obstacles, such as women-centred SRHC and no assigned healthcare profession for men's sexual and reproductive health issues, hindered men's access to SRHC. Lastly, the literature rarely discussed the impact of health policies on men's access to SRHC. CONCLUSIONS The literature lacked the perspectives of specific groups of men such as migrants, men who have sex with men and transmen, as well as the experiences of men in SRHC related to sexual function, contraceptive use and gender-based violence. These knowledge gaps, taken together with the lack of a clear entry point for men into SRHC, indicate the necessity of an improved health and medical education of healthcare providers, as well as of health system interventions.

Molecular Epidemiology of the HIV-1 Subtype B Sub-Epidemic in Bulgaria. Viruses 2020; 12:v12040441.

Abstract
HIV-1 subtype B is the predominant strain in Bulgaria, yet little is known about the molecular epidemiology of these infections, including its origin and transmissibility. We used a phylodynamics approach by combining and analyzing 663 HIV-1 polymerase (pol) sequences collected from persons diagnosed with HIV/AIDS between 1988-2018 and associated epidemiologic data to better understand this sub-epidemic in Bulgaria. Using network analyses at a 1.5% genetic distance threshold (d) we found several large phylogenetic clusters composed mostly of men who have sex with men (MSM) and male heterosexuals (HET). However, at d = 0.5%, used to identify more recent transmission, the largest clusters dissociated to become smaller in size. The majority of female HET and persons with other transmission risks were singletons or pairs in the network. Phylogenetic analysis of the Bulgarian pol sequences with publicly available global sequences showed that subtype B was likely introduced into Bulgaria from multiple countries, including Israel and several European countries. Our findings indicate that subtype B was introduced into Bulgaria multiple times since 1988 and then infections rapidly spread among MSM and non-disclosed MSM. These high-risk behaviors continue to spread subtype B infection in Bulgaria as evidenced by the large clusters at d = 0.5%. Relatively low levels of antiretroviral drug resistance were observed in our study. Prevention strategies should continue to include increased testing and linkage to care and treatment, as well as expanded outreach to the MSM communities.

Abstract
INTRODUCTION Human papillomavirus (HPV) infection is transmitted through skin-to-skin contact, and vaginal and anal sex are the most common transmission routes. Sex workers and men who have sex with men (MSM) are more exposed to the virus, and therefore, a higher frequency of this infection would be expected. The prevalence of HPV infection types and the forms and factors of transmission must be investigated to control infection-related outcomes. This protocol study will be the first nationwide study with a uniform methodology to evaluate HPV prevalence of and infection types among sex workers and MSM in Brazil. METHODS AND ANALYSIS This multicentre cross-sectional study will be conducted with a respondent-driven sampling method to recruit 1174 sex workers and 1198 MSM from all regions of Brazil. The study will consist of preliminary interviews to verify the eligibility criteria and characterise the network size as well as a second questionnaire to obtain sociodemographic, behavioural and sexual information. Specimens from the oral cavity and anal and cervical or penile/scrotal sites will be collected. All HPV samples will be processed in a certified central laboratory. Other sexually transmitted infections will be evaluated by interview and by rapid testing for HIV and syphilis. Strict quality control will be conducted using different procedures, including the training and certification of the health professionals responsible for acquiring data and monitoring visits. ETHICS AND DISSEMINATION The project was approved by the research ethics committee of the main institution and the corresponding ethics committees of the recruitment sites. Due to the literature gap on the sexual health of sex workers and MSM and the intense stigma surrounding these populations, a critical analysis of the study results will contribute to epidemiological knowledge and will be useful for the development of strategies against virus morbidities.
