Chemsex among gay, bisexual, and other men who have sex with men in Singapore and the challenges ahead: A qualitative study

Chemsex Among Men Who Have Sex With Men: A Systematic Scoping Review of Research Methods

Chemsex refers to the use of psychoactive substances with sex. We carried out a systematic scoping review of methodological characteristics of chemsex research among men who have sex with men (MSM), published between 2010 and 2020. For inclusion, chemsex had to be the main focus, and studies had to specify GHB/GBL, stimulant (amphetamine, crystal meth, ecstasy/MDMA, cathinones, cocaine) and/or ketamine use with sex as a variable. From 7055 titles/abstracts, 108 studies were included, mostly cross-sectional, and from Western countries. About one-third of studies recruited exclusively from clinical settings. A majority of these recruited from sexually transmitted infection (STI) clinics. The included quantitative studies analyzed possible associations between chemsex and STI health (40%), mental health (15%), drug health (12%), sexological health (10%), and post-diagnostic HIV health (7%). Most studies included GHB/GBL and crystal meth in their operationalization of chemsex. Definitions and operationalizations of chemsex vary greatly in the literature, and researchers of chemsex among MSM should consider ways in which this variation impacts the validity of their results. More studies are needed among MSM in non-high income and non-Western countries, and examination of possible links between chemsex and post-diagnostic HIV health, sexological health, and mental health.

Can platform use patterns be an indicator of HIV-related risk and sub-group heterogeneity among men who have sex with men in Singapore: a latent class analysis

Introduction

Low-level HIV epidemic settings like Singapore face the challenge of reaching men at-risk who have less contact with programmes. We investigated patterns of meeting platform use by men seeking male sexual partners (MSM) as potential marker of risk to differentiate sub-groups for interventions.

Methods

Latent Class Analysis (LCA) was applied to a survey sample of MSM recruited from bars/clubs, saunas and a smartphone application, using purposive sampling. The best-fit LCA model which identified homogeneous sub-groups with similar patterns of meeting platform was factored in multivariable regression to identify associations with risk behaviors on the pathway to HIV infection.

Results

Overall 1,141 MSM were recruited from bars/clubs (n = 426), saunas (n = 531), and online (n = 184). Five patterns emerged, reflecting salient platform use characteristics: Sauna-centric (SC; n = 413), App-centric (AC; n = 276), Multiple-platforms (MP; n = 123), Platform-inactive (PI; n = 257), and "Do not hook up" (DNH; n = 72) classes. Men in the SC and MP classes had high probabilities of using saunas to meet partners; SC were older and less likely to have disclosed their sexual orientation. The MP class had high probabilities of connecting across all platforms in addition to saunas and more likely to have disclosed their sexual orientation, than the PI class. Men in the SC and MP classes had twice the odds of reporting multiple sex partners (aORSC = 2.1; 95%CI: 1.33.2; aORMP = 2.2; 95%CI: 1.14.6). Single/non-partnered MSM and those using alcohol/drugs during sex had 1.7 (95%CI: 1.22.5) and 3.2 (95%CI: 2.05.1) the odds respectively, of reporting multiple sex partners. The SC and MP classes had higher odds of engaging in group sex while MSM using alcohol/drugs during sex had twice the odds of reporting group sex. Alcohol/drugs and group sex were independently associated with condomless sex (as was lower education). Group sex, alcohol/drugs during sex, disclosure of sexual orientation or being Singaporean/permanent resident were associated with recent testing for HIV.

Discussion

The five distinct risk profiles identified can help tailor differentiated HIV interventions-combined with field knowledge and other prevention-to expand HIV self-testing, Pre-Exposure Prophylaxis and other services (e.g., Mpox vaccination) to sub-groups at risk.

Navigating drug use, cessation, and recovery: a retrospective case notes review among sexual minority men at a community-based service in Singapore

BACKGROUND

In Singapore, where drug use is a highly stigmatized and criminalized issue, there is limited understanding of the challenges faced by individuals, particularly sexual minority men, in their journey towards recovery from substance dependence or addiction. This qualitative study aimed to investigate the driving forces behind drug use, the factors contributing to drug cessation, and the elements influencing the recovery process.

METHODS

Data were extracted from clinical records provided by  The Greenhouse Community Services Limited between January 2020 to May 2022. These records encompassed information from four distinct forms: the intake assessment, progress notes, case closing summary, and the care plan review. Thematic analysis was employed to identify and categorize recurring themes within the data.

RESULTS

Data from beneficiaries (n = 125) were analyzed and yielded a series of themes related to facilitators of drug use, motivations to cease drug use, and managing one's ongoing recovery. Within the facilitators of drug use, two sub-themes were identified: (a) addressing trauma and triggers and (b) managing emotions. Additionally, managing one's recovery was marked by four significant sub-themes: (a) uncovering personal identities, (b) losing motivation and drive, (c) overcoming obstacles, and (d) preparing for aftercare.

CONCLUSIONS

The study contributes valuable insights into the dynamics of ongoing recovery management, offering potential avenues for interventions that could enhance support for individuals in their journey to overcome substance dependence. Enhancing psychoeducation and fostering peer support have the potential to facilitate the recovery process. Clearly, a holistic approach is needed to address these complex issues that cuts across our societies.

An object-oriented analysis of social apps, syringes and ARTs within gay Taiwanese men's chemsex practices

Critical drug studies explore the discursive and material dimensions of sexualised drug use to overcome individualised and often pathologising notions such as risk, safety, responsibility and pleasure. This article uses an object-oriented approach-following the use and flow of social apps, syringes and antiretroviral therapy (ART)-to analyse gay and bisexual Taiwanese men's drug practices. Interview data from fourteen men are used to articulate how objects were brought into gay and bisexual men's chemsex repertoire in ways that shaped individuals' safe-sex communication, intimacy maintenance and stigma negotiation. An object-oriented approach scrutinises risk, pleasure and identities in assemblages of the human and nonhuman, and can help identify new opportunities for implementing health promotion interventions and policies.

Exploring practices to enhance benefits and reduce risks of chemsex among gay, bisexual, and other men who have sex with men: A meta-ethnography

BACKGROUND

Chemsex is the intentional combining of specific drugs with sex, primarily by gay, bisexual, and other men who have sex with men (GBMSM), to enhance intimacy, pleasure, and prolong sexual sessions. Practices vary across geographic and social settings. Participants report benefits and risks of chemsex. Studies have previously reviewed chemsex practices and harm reduction interventions separately. This review aims to examine both together by describing and understanding practices that men employ to navigate the perceived benefits and risks of chemsex.

METHODS

We conducted a systematic meta-ethnographic review of published qualitative literature, screening titles, abstracts, and full texts on defined inclusion and exclusion criteria. Using reciprocal and refutational translation techniques, we analysed study participants' (first-order) and researchers' (second-order) accounts of benefit-enhancing and risk-reducing chemsex practices. Finally, we employed line-of-argument synthesis techniques to develop our own higher-level interpretations (third-order constructs) of these chemsex practices.

RESULTS

Our search yielded 6356 records, from which, we included 23 articles in our review. Most studies were conducted in high-income Western countries. Across studies, participants acted at the individual, interpersonal, and community levels to enhance benefits and reduce risks, which made up our third-order constructs. Eight themes emerged from first- and second-order constructs to describe these practices, which included personal preparation, personal boundaries, biomedical measures, structured use of drugs, leaning on partners, injecting practices, group organising, watching out for others, and teaching and learning. Contextual factors like trust, agency, access, stigma, and setting moderated whether and how participants engaged in these practices, and if practices enhanced benefits or reduced risks.

CONCLUSION

Health promotion programmes and research focused on chemsex must account for the benefits and the risks that GBMSM associate with this type of sexualised drug use and target the moderating factors that shape the practices they employ to navigate these benefits and risks.

Racial/Ethnic Disparities in Club Drug Use, Situational Club Drug Use during Sex, and Sexual Risk Behaviors among Alcohol-Using Men Who Have Sex with Men (MSM) in San Francisco

BACKGROUND

Club drug use-including 3,4-Methylenedioxymethamphetamine, ketamine, crack/cocaine, hallucinogens, gamma hydroxybutyrate, volatile nitrites, and methamphetamine-has been linked to sexual risk behaviors among MSM. Few studies examine how the use of club drugs and the association between club drug use during sex and sexual risk may differ by race/ethnicity.

METHODS

Using data from a cross-sectional study among alcohol-using MSM in San Francisco (n = 252), we examined the associations between the interaction of race/ethnicity and club drug use during sex, and the following behavioral outcomes: any condomless anal intercourse (CAI), insertive CAI, receptive CAI, and any serodiscordant sex in the past six months. All models controlled for income, HIV status, relationship status, age, and current use of a biomedical HIV prevention tool (i.e., Pre-Exposure Prophylaxis [PrEP] or antiretroviral therapy).

RESULTS

There were significant racial differences in club drug use (p < 0.001) and club drug use during sex (p = 0.01). Asian/Pacific Islander (API) and Latino participants reported using club drugs the most at 78.8% and 79%, respectively. Among users of club drugs, club drug use during sex was most common among Black (100%), and Latino MSM (93%). Significant interactions between race/ethnicity and club drug use during sex were observed for CAI (p = 0.02), insertive CAI (p = 0.01), and receptive CAI (p = 0.01). API participants who used club drug during sex had higher odds of reporting CAI (aOR = 15.27, CI = 1.50-155.34), insertive CAI (aOR = 21.11, CI = 2.04-218.10), and receptive CAI (aOR = 21.11, CI = 2.04-218.10).

CONCLUSIONS

Given the differing rates of club drug use during sex by race/ethnicity and the role race/ethnicity plays in modifying the relationships between club drug use during sex and sexual risk behaviors, culturally-tailored interventions may be needed to address the needs of ethnically-diverse, club drug-using MSM.

Understanding and preventing the advertisement and sale of illicit drugs to young people through social media: A multidisciplinary scoping review

ISSUES

The sale of illicit drugs online has expanded to mainstream social media apps. These platforms provide access to a wide audience, especially children and adolescents. Research is in its infancy and scattered due to the multidisciplinary aspects of the phenomena.

APPROACH

We present a multidisciplinary systematic scoping review on the advertisement and sale of illicit drugs to young people. Peer-reviewed studies written in English, Spanish and French were searched for the period 2015 to 2022. We extracted data on users, drugs studied, rate of posts, terminology used and study methodology.

KEY FINDINGS

A total of 56 peer-reviewed papers were included. The analysis of these highlights the variety of drugs advertised and platforms used to do so. Various methodological designs were considered. Approaches to detecting illicit content were the focus of many studies as algorithms move from detecting drug-related keywords to drug selling behaviour. We found that on average, for the studies reviewed, 13 in 100 social media posts advertise illicit drugs. However, popular platforms used by adolescents are rarely studied.

IMPLICATIONS

Promotional content is increasing in sophistication to appeal to young people, shifting towards healthy, glamourous and seemingly legal depictions of drugs. Greater inter-disciplinary collaboration between computational and qualitative approaches are needed to comprehensively study the sale and advertisement of illegal drugs on social media across different platforms. This requires coordinated action from researchers, policy makers and service providers.

Lesbian, gay, bisexual, transgender, queer and intersex (LGBTQI+) healthcare in Singapore: perspectives of non-governmental organisations and clinical year medical students

PURPOSE

International studies document that lesbian, gay, bisexual, transgender, queer and intersex (LGBTQI+) patients face significant health disparities. Studies exploring the attitudes, knowledge, preparedness and comfort levels of healthcare students towards LGBTQI+ health have been conducted in the United States, United Kingdom and Malaysia. This study aims to investigate stigma in healthcare for LGBTQI+ patients in Singapore, and possible upstream factors within medical education.

METHODS

This mixed-methods study adopts a convergent parallel design. The Health Stigma and Discrimination Framework was referenced to devise in-depth interviews with representatives from 13 LGBTQI-affirming non-governmental organisations, analysed through thematic analysis. 320 clinical medical students were surveyed about attitudes, knowledge, comfort, preparedness, and perceived importance of/towards LGBTQI+ health, analysed via descriptive statistics and multivariate regression.

RESULTS

Prevailing stigma in Singaporean society against LGBTQI+ individuals is exacerbated in healthcare settings. Doctors were cited as unfamiliar or uncomfortable with LGBTQI+ health, possibly from lack of training. Among medical students surveyed, the median composite attitudes, comfort and preparedness index was 3.30 (Interquartile Range (IQR) = 0.50), 3.17 (IQR = 0.83), 2.50 (IQR = 1.00) respectively. Only 12.19% of students answered all 11 true-false questions about LGBTQI+ health correctly.

CONCLUSION

Medical students in Singapore have scored sub-optimally in their knowledge and preparedness towards LGBTQI+ health, while interpersonal and structural stigma in healthcare towards LGBTQI+ people in Singapore negatively affects health and wellbeing. These findings are an impetus to improve medical training in this area. High scores among medical students in attitudes, comfort and perceived importance of LGBTQI+ topics demonstrate that there is space for LGBTQI+ health in the local medical education curriculum. Curricular interventions can prioritise content knowledge, communication skills and sensitivity.

Hi-fun among men who have sex with men in Bangkok: A scoping study exploring key informants' perspectives on hi-fun contexts, harms and support strategies

The use of specific drugs (e.g. methamphetamine, GHB/GBL and other stimulants) to enhance sex among men who have sex with men (MSM), is the focus of global public health concern because of links to social harms, poor mental and sexual health. Often called 'chemsex' in Western settings or 'hi-fun' in Southeast Asia, this type of sexualised drug use is increasingly visible in Thailand where the unique sociocultural and legislative environments shape sexual cultures and harms. This study aimed to develop an understanding of key informants' perspectives on hi-fun contexts, harms and current responses in Bangkok. In-depth interviews were conducted with thirteen key informants from clinical, community, policy and development organisations. Four key informants had personal experience of hi-fun. Interviews covered hi-fun contexts, harms and support, were transcribed verbatim, translated to English (where necessary) and analysed using a thematic framework. MSM hi-fun 'influencers' shape norms and provide support online, primarily through Twitter. Hi-fun was linked to Westernisation and wealth; complex hierarchies emerged from asymmetries in social/financial capital. Police coercion towards MSM engaged in hi-fun was a concern. Given the nature of their funding, HIV/HCV/STI transmission was the most pressing focus for many organisations, however key informants were concerned especially about drug overdoses and mental health/well-being impacts. The political and economic context means funding for MSM health in Thailand focuses primarily on HIV prevention/treatment; restrictions on development aid constrain holistic hi-fun focused service development. Most hi-fun support was informally developed; successful strategies relied on partnership working and peer developed/delivered services, some of which were adapted from high-income settings. Despite substantial barriers, organisations developed services responding to the needs of MSM engaged in hi-fun. Given that many were informally developed or adapted from high-income settings, establishing a theoretical basis for further interventions that is grounded in this unique context is a priority.

Considerations and recommendations for mHealth interventions for substance use among Sexual and Gender Minority (SGM) individuals: A narrative review of the past 5 years

Purposeof Review

The prevalence of problematic substance use is disproportionately higher among sexual and gender minority (SGM) adults compared to adults in the general population. mHealth as a treatment modality could reduce barriers to accessing substance use treatments among SGM populations. Through a qualitative literature search, the current narrative review aimed to understand the lived experiences of SGM individuals who use substances and to synthesize recommendations made in the literature to inform future mHealth interventions.

Recent Findings

Positive and negative reinforcement motives were prominent reasons for substance use, which included SGM identity expression and conformity motives. Individual- and system-level treatment barriers included a lack of safe and nonjudgmental environment, shame and stigma, and limited knowledge about treatment options. Barriers were directly linked to the reported substance use treatment needs in this population.

Summary

On-demand app features, real-time intervention and assessment, and anonymity should be considered in future mHealth trials.

Utilization of mental health services in relation to the intention to reduce chemsex behavior among clients from an integrated sexual health services center in Taiwan

INTRODUCTION

The intention of chemsex-practicing gay and bisexual men and other men who have sex with men (GBMSM) to reduce their drug use is an important factor for the utilization of harm reduction services. This study aimed to examine data from an integrated sexual health services center to understand the relationship between the intention to reduce chemsex behavior and chemsex-related utilization of mental health services among GBMSM who engage in chemsex.

METHOD

We used data collected from Healing, Empowerment, Recovery of Chemsex (HERO), an integrated health center in Taiwan, between November 2017 and December 2021. As the baseline, clients were asked to rate the current and ideal proportions of their sexual activities that involved the use of MDMA, ketamine, methamphetamine, GHB/GBL, or mephedrone. Having the intention to reduce chemsex was defined as having a lower proportion of ideal engagement compared to actual engagement. The data on the use of the services provided at HERO were linked to the survey responses and compared to information gathered during regular follow-up visits. Univariable and multivariable logistic regression analyses and a Poisson regression analysis were performed on the data.

RESULTS

A total of 152 GBMSM reported engaging in chemsex, of whom 105 (69.1%) expressed the intention to reduce their chemsex behavior. Service utilization ranged from 23.0% for participating in meetings of a chemsex recovery group, 17.1% for visiting a mental health clinic, and 10.5% for using both of these services. The intention to reduce chemsex behavior significantly associated with visiting a mental health clinic (aOR = 4.68, p < 0.05), but its association with attending meetings of a chemsex recovery group was only marginally significant (aOR = 2.96, p < 0.1). Other factors that remained significantly associated with service use were a high frequency of substance use and living with HIV.

CONCLUSION

Comprehensive harm reduction strategies, which touch on mental health, drug use management and recovery, are needed for those who want to reduce their chemsex behavior. Public health practitioners should endeavor to raise awareness of resources that are available for people who engage in chemsex and to minimize the barriers blocking their access to the appropriate services.

Taking Flight: Narratives, Logistics, and Risks of Chemsex Scenes in the Philippines

Chemsex - the use of specific, illicit substances to facilitate and enhance sexual encounters - has been documented extensively across the Global North using qualitative methodologies. Elsewhere, however, little is known about the phenomenon. Our article addresses this gap in the scholarly literature by exploring how chemsex encounters transpire in the Philippines. Through semi-structured interviews, we demonstrate the spatiotemporal nature of chemsex scenes, showing how people move between physical and virtual domains across time as they find sexual partners, procure drugs, and organize and attend the actual encounter. Consequently, the risks faced by chemsex practitioners - to health and to security - are also spatiotemporally plotted within intersecting physical and virtual risk environments, and best mitigated by a form of experiential expertise that is likewise temporally determined. Ultimately, chemsex scenes in the Philippines are distinguished from the rest of the world by the state-led "war on drugs." We consider our findings in the context of this war, showing how its very real and often fatal threats have shaped the way people navigate chemsex scenes and mitigate the risks through "counterpublic health" measures, and how its prominent ideologies and discourses are reflected in the ways by which people make sense of their drug use.

Factors associated with sexually transmitted shigella in men who have sex with men: a systematic review

BACKGROUND

Outbreaks of sexually transmitted shigella have been reported in men who have sex with men (MSM) since the 1970s and present a major public health issue. Understanding the factors associated with the sexual transmission of shigella may inform future control strategies.

METHODS

We systematically searched four bibliographical databases (January 2000-February 2022) for manuscripts in English. We used a two-stage process to assess eligibility: the primary author conducted an initial screen and then three authors conducted independent full-text reviews to determine the final eligible manuscripts. We only included manuscripts that included MSM diagnosed with sexually transmitted shigella where specific factors associated with transmission were identified.

RESULTS

Thirteen manuscripts met the inclusion criteria that included 547 individuals. Sexually transmitted shigella in MSM was associated with: residing in a capital city/urban region, living with HIV (including engaging in seroadaptive sexual behaviour, having a low CD4 count, having a HIV viral load >100 000 and not engaging with HIV care), using HIV pre-exposure prophylaxis, use of geospatial mobile phone applications to meet sexual partners, visiting sex on premises venues, chemsex and recreational drug use, sexual behaviour (including multiple non-regular sexual partners and oral-anal sexual contact) and concomitant STIs.

CONCLUSION

We have highlighted some important risk behaviours and factors that are associated with sexually transmitted shigella in MSM that can be used to target future shigella control interventions.

Prevalence of sexualized drug use and risk of HIV among sexually active MSM in East and South Asian countries: systematic review and meta-analysis

INTRODUCTION

Sexualized drug use (SDU), the use of psychoactive drugs in the context of sexual intercourse, has been identified as a risk factor for HIV among men who have sex with men (MSM) in Asia. Given the distinct social and cultural context of same-sex relationships and drug-using practice in Asia, we aimed to describe the prevalence of SDU in East and South Asian countries and its associations with condomless anal sex (CAI) and HIV status. Synthesizing SDU research in this region, including SDU definitions, prevalence and outcomes, provides insights to inform future research and improved programme planning, resourcing and advocacy.

METHODS

We systematically searched OVID Medline, OVID EMBASE, OVID Global Health, CINAHL, PsycINFO and SCOPUS publication databases for scientific articles published from 1990 to 2022 measuring SDU among MSM in East and South Asian countries. A narrative synthesis was utilized to describe key study attributes and findings, and meta-analyses using random pooled effect models were used to estimate SDU prevalence and its associations with CAI and HIV status. Subgroup meta-analyses, sensitivity analysis and assessment of publication bias examined potential sources of heterogeneity for the pooled SDU prevalence estimates.

RESULTS AND DISCUSSION

Of the 1788 publications screened, 49 publications met the selection criteria and 18 were suitable for meta-analyses. Findings highlight SDU definitions distinct from other regions but inconsistencies in the definition of SDU between studies that have been highlighted in research elsewhere. The pooled prevalence of recent SDU (past 12 months) was 13% (95% CI = 10-16%; I2 = 97.6) but higher when studies utilized self-administered surveys (15%; 95% CI = 12-19%; p<0.05). SDU was associated with greater odds of CAI (pooled odds ratio [OR] = 3.21; 95% CI = 1.82-5.66) and living with diagnosed HIV (OR = 4.73; 95% CI = 2.27-8.21).

CONCLUSIONS

SDU is common among MSM in East and South Asian countries, but varying SDU definitions limit between-study comparisons. Responses to SDU-related harms should consider local contexts, including specific drug types used and their relative risks.

Using Intervention Mapping to Develop an mHealth Intervention to Support Men Who Have Sex With Men Engaging in Chemsex (Budd): Development and Usability Study

BACKGROUND

Chemsex refers to the intentional use of drugs before or during sex among men who have sex with men (MSM). Engaging in chemsex has been linked to significant negative impacts on physical, psychological, and social well-being. However, no evidence-based support tools have addressed either these harms or the care needs of MSM who engage in chemsex.

OBJECTIVE

The purpose of this paper was to describe the development of a mobile health intervention (named Budd) using the intervention mapping protocol (IMP). Budd aims to support and inform MSM who participate in chemsex, reduce the negative impacts associated with chemsex, and encourage more reasoned participation.

METHODS

The IMP consists of 6 steps to develop, implement, and evaluate evidence-based health interventions. A needs assessment was carried out between September 2, 2019, and March 31, 2020, by conducting a literature study and in-depth interviews. Change objectives were selected based on these findings, after which theory-based intervention methods were selected. The first version of the intervention was developed in December 2020 and pilot-tested between February 1, 2021, and April 30, 2021. Adjustments were made based on the findings from this study. A separate article will be dedicated to the effectiveness study, conducted between October 15, 2021, and February 24, 2022, and implementation of the intervention. The Budd app went live in April 2022.

RESULTS

Budd aims to address individual factors and support chemsex participants in applying harm reduction measures when taking drugs (drug information, drug combination tool, and notebook), preparing for participation in a chemsex session (articles on chemsex, preparation tool, and event-specific checklist), planning sufficient time after a chemsex session to recover (planning tool), seeking support for their chemsex participation (overview of existing local health care and peer support services, reflection, personal statistics, and user testimonials), taking HIV medication or pre-exposure prophylaxis in a timely manner during a chemsex session (preparation tool), and contacting emergency services in case of an emergency and giving first aid to others (emergency information and personal buddy).

CONCLUSIONS

The IMP proved to be a valuable tool in the planning and development of the Budd app. This study provides researchers and practitioners with valuable information that may help them to set up their own health interventions.

The World Federation of Societies of Biological Psychiatry guidelines on the assessment and pharmacological treatment of compulsive sexual behaviour disorder

OBJECTIVES

The current guidelines aim to evaluate the role of pharmacological agents in the treatment of patients with compulsive sexual behaviour disorder (CSBD). They are intended for use in clinical practice by clinicians who treat patients with CSBD.

METHODS

An extensive literature search was conducted using the English-language-literature indexed on PubMed and Google Scholar without time limit, supplemented by other sources, including published reviews.

RESULTS

Each treatment recommendation was evaluated with respect to the strength of evidence for its efficacy, safety, tolerability, and feasibility. Psychoeducation and psychotherapy are first-choice treatments and should always be conducted. The type of medication recommended depended mainly on the intensity of CSBD and comorbid sexual and psychiatric disorders. There are few randomised controlled trials. Although no medications carry formal indications for CSBD, selective-serotonin-reuptake-inhibitors and naltrexone currently constitute the most relevant pharmacological treatments for the treatment of CSBD. In cases of CSBD with comorbid paraphilic disorders, hormonal agents may be indicated, and one should refer to previously published guidelines on the treatment of adults with paraphilic disorders. Specific recommendations are also proposed in case of chemsex behaviour associated with CSBD.

CONCLUSIONS

An algorithm is proposed with different levels of treatment for different categories of patients with CSBD.

HIV, chemsex, and the need for harm-reduction interventions to support gay, bisexual, and other men who have sex with men

Numerous studies have identified an association between the use of drugs in sexual contexts (chemsex) and HIV among gay, bisexual, and other men who have sex with men (GBMSM), although whether a causal relationship exists is contentious. An intricate relationship exists between chemsex, HIV treatment and prevention, harm reduction, and the provision of community-grounded health services. Furthermore, potential harms exist beyond HIV, such as intoxication and overdose. Community-engaged responses to chemsex involve social and cultural strategies of harm reduction and sexual health promotion before, during, and after a chemsex session. Ultimately, this Review calls for actions and collaborations aimed at developing a greater understanding of chemsex as a practice within different GBMSM subpopulations and to develop tailored harm-reduction models that can accommodate GBMSM who engage in chemsex in various ways and with varied effects.

Perceptions of hepatitis C treatment and reinfection risk among HIV-positive men who have sex with men and engage in high risk behaviours for hepatitis C transmission: The CEASE qualitative study

BACKGROUND

Globally, treatment uptake for hepatitis C virus (HCV) infection among HIV-HCV coinfected men who have sex with men (MSM) has substantially increased since the advent of interferon-free direct-acting antivirals (DAA). However, HIV-positive MSM who engage in high risk behaviours are at an increased risk of HCV reinfection post-treatment. The aim of this study was to investigate perceptions of HCV diagnosis, treatment and reinfection risk among HCV-HIV coinfected MSM who engage in drug use and/or high risk sexual behavior in Sydney, Australia.

METHODS

Participants were recruited from the Control and Elimination within AuStralia of HEpatitis C from people living with HIV (CEASE) cohort (n=402) who reported engaging in drug use and/or high risk sexual behavior for transmission of HCV infection. Participants were interviewed about their perceptions of HCV diagnosis, treatment, and reinfection risk. Interview data were transcribed, coded, and analyzed thematically.

RESULTS

Of 33 participants interviewed (mean age 49 years), many participants were 'shocked' by their HCV diagnosis. Participants who believed they acquired HCV infection through sexual exposure felt it was important that their healthcare practitioner agreed with their perspective to mitigate stigmatizing experiences. Overall, participants expressed high satisfaction with their treatment experience due to long-standing therapeutic relationships with their HIV physician. Many participants expressed knowledge of how to prevent HCV reinfection from injection drug use, yet other than condom usage, most were unsure how to reduce high risk sexual activity with such discussions occurring less frequently with healthcare practitioners.

CONCLUSION

Findings indicate that MSM who engage in drug use and high risk sexual activity would benefit from additional education on reducing reinfection risk through sexual activity and services to reduce substance use, if requested.

The Syndemic of Substance Use, High-Risk Sexual Behavior, and Violence: A Qualitative Exploration of the Intersections and Implications for HIV/STI Prevention Among Key Populations in Lagos, Nigeria

Background

Key populations (KP) are defined groups with an increased risk of HIV due to specific higher risk behaviours. KP who use substances engage in risky behaviors that may play a co-active role in HIV transmission and acquisition in Nigeria. This qualitative study explored the 'syndemics' of substance use, sexual risk behavior, violence and HIV infection among KP who use substances.

Methods

Nineteen sexually active men who have sex with men [MSM] and 18 female sex workers [FSW] aged 16 years and older who use substances were purposively selected to participate in sixteen in-depth interviews and two focus groups. We utilized a syndemic framework to explore the interaction of socio-economic factors, substance use and high-risk sexual practices. The interviews were audio-recorded, transcribed, organized in NVIVO 11 and analyzed using thematic analysis.

Results

Majority (95%) were non-injection substance users (primarily alcohol and marijuana); a few KP also used cocaine and heroin. Sixty percent of participants were between 16-24 years. Substance use utilities and trajectories were heavily influenced by KP social networks. They used substances as a coping strategy for both physical and emotional issues as well as to enhance sex work and sexual activities. Key HIV/STI risk drivers in the settings of substance use during sexual intercourse that emerged from this study include multiple sexual partnerships, condom-less sex, transactional sex, intergenerational sex, double penetration, rimming, and sexual violence. Poverty and adverse socio-economic conditions were identified as drivers of high-risk sexual practices as higher sexual risks attracted higher financial rewards.

Conclusions and Recommendations

Findings indicate that KP were more inclined to engage in high-risk sexual practices after the use of substances, potentially increasing HIV risk. The syndemic of substance use, high-risk sexual behavior, adverse socio-economic situations, and violence intersect to limit HIV prevention efforts among KP. The behavioural disinhibition effects of substances as well as social and structural drivers should be considered in the design of targeted KP HIV prevention programs. HIV intervention programs in Nigeria may yield better outcomes if they address the nexus of sexual risk behavior and substance use as well as knowledge and appropriate use of HIV prophylaxis.

"White, Tall, Top, Masculine, Muscular": Narratives of Intracommunity Stigma in Young Sexual Minority Men's Experience on Mobile Apps

What forms of intracommunity stigma do young sexual minority men narrate as they participate in communities through mobile apps? In a content analysis of 32 interviews with a racially diverse sample of young sexual minority men (ages 19-25; 84.4% non-White) from four regions of the USA, a majority of men (62.5%) spontaneously discussed mobile apps (e.g., Grindr, Scruff) when asked about their experience of community more broadly. Men's narratives revealed engagement with intracommunity stigma related to body size, race/ethnicity, gender expression, and sexual position (e.g., bottom). Stigma related to HIV status, substance use, and social class were not spontaneously narrated in response to questions about men's experience in communities. Expressions of stigma were frequently experienced intersectionally, particularly regarding racialized stereotype expectations (e.g., "Asian men are twinks, effeminate"). We discuss the ways in which sexual minority men reproduce dominant ideologies related to racism, misogyny, and masculine body ideals as they engage with one another on mobile apps. To the extent that many young men rely on mobile apps for community connection, their experiences of community might serve to exacerbate, rather than ameliorate, the deleterious impact of stigma.

Risky Sexual Practices, Sexually Transmitted Infections, Motivations, and Mental Health among Heterosexual Women and Men Who Practice Sexualized Drug Use in Spain

Sexualized drug use (SDU) has been poorly studied among heterosexuals. The purpose of the present study was to analyze the prevalence of and gender differences in types of substances, risky sexual practices, sexually transmitted infections (STIs), motivations, and psychological adjustment among heterosexual women and men who engage in SDU. The study sample consisted of 1181 heterosexuals (795 women) between 18 and 78 years old (mean age = 24.4, SD = 7.4). Approximately 12% of the participants had engaged in SDU. No differences were found in the prevalence of SDU between men and women. Alcohol, cannabis, and 3,4-methylenedioxy-methamphetamine (MDMA) were the substances most frequently used for sexual purposes. Men were significantly more likely to use MDMA, ecstasy, cocaine, and erectile dysfunction (ED) drugs, and they tended to have more sexual partners than women. Likewise, SDU was related to have more sexual partners, penetrative sex without a condom, practice a fetish, be diagnosed with syphilis, chlamydia, and others STIs, and present more depression symptoms (but not with more anxiety). In conclusion, SDU was associated with poorer physical and mental health. It is, therefore, necessary to design programs aimed at reducing the incidence of the consequences of SDU on the physical and mental health of both men and women. Moreover, programs that seek to understand why these individuals engage in SDU should be undertaken.

Harm Minimisation Drug Policy Implementation Qualities: Their Efficacy with Australian Needle and Syringe Program Providers and People Who Inject Drugs

(1) Background: Policies and laws in several jurisdictions across the globe have aimed to promote harm minimisation or reduction, through the implementation of Needle and Syringe Programs (NSP) for people who inject drugs (PWID), for whom abstinence may not be possible or desired. While NSPs hold great promise, their implementation qualities are understudied. (2) Aim: We aimed to examine the implementation quality priorities of NSP providers and PWID consumers in an Australian setting. (3) Method: This study utilised a Quantitative-qualitative (QUAN-qual) mixed methods approach. Survey participants included both PWID (n = 70) and NSP providers (n = 26) in Australia. (4) Results: Results following non-parametric data analysis indicate NSP providers prioritised NSP implementation qualities in the following order: compatibility, observability, relative advantage, resourcing and trialability. Contrary to which, PWID prioritised resourcing, compatibility, relative advantage and trialability, respectively. Findings demonstrate that efficacy of implementation qualities is dependent on the juxtaposition of service provision and utilisation whereby implementation quality priorities are balanced. (5) Conclusions: This research presents novel findings guiding NSP harm reduction programmes for sustainability framed on provider and consumer implementation quality priorities. We envisage future studies on boundary conditions of NSP harm reduction implementation in other jurisdictions.

Sex in Chemsex: Sexual Response, Motivations, and Sober Sex in a Group of Italian Men Who Have Sex With Men With Sexualized Drug Use

BACKGROUND

Most studies on chemsex focus on the health risks associated with the practice, whereas less attention has been paid to the perception of sexual gratification in men who have sex with men (MSM) who use these substances.

AIM

The purpose of this study was to explore the effects of chemsex substances on sexual response, motivations to engage in chemsex and the relationship with sober sex.

METHODS

Thirty-one Italian cisgender MSM involved in sexualized drug use were interviewed and transcripts were thematically analyzed.

OUTCOMES

An ad hoc grid exploring sociodemographic data, chemsex sexual experience, motives, and relationships with sober sex was used during telephone-based interviews.

RESULTS

Participants showed significant individual differences in how chems may affect their sexual experience. The most reported effects were an increase in sexual desire and subjective arousal, access to higher disinhibition, possible erection and ejaculation difficulties, significant extension of the sexual experience duration, and an intensified perception of intimacy and pleasure. All the positive outcomes of substances on sex creates a great curiosity around chemsex, which is among the primary motives to engage in chemsex for the first time. Over time, other motives may emerge, also connected to substance abuse and craving. Some men reported to be motivated by their partners and friends and to use chemsex to cope with depressive mood/anxiety symptoms, stress and sexual problems. Many differences were reported between chemsex and sober sex. Chemsex seems to embody the idea of transgressive and exciting sex, while sober sex is outlined as a more intimate encounter, that can be significantly affected by performance anxiety.

CLINICAL TRANSLATION

These results offer some new perspectives that may add interesting information to the literature and be fundamental for future prevention and harm-reduction projects.

STRENGTHS & LIMITATIONS

Although this study is based on a small group of Italian MSM and the interviews were not audio-recorded, transcripts were consistent with scientific literature that considers it important to pay attention to the positive links between sex and substance use.

CONCLUSION

The promotion of safer sexual behavior should contemplate an in-depth discussion and recognition of both pleasurable and distressing aspects of chemsex sexual experience, its motivations over time and perceived differences with sober sex.

Exploring the role of trauma in underpinning sexualised drug use ('chemsex') among gay, bisexual and other men who have sex with men in Singapore

BACKGROUND

Sexualised drug use (SDU) has been identified as a major risk factor for HIV, as well as other mental health comorbidities among gay, bisexual and other men who have sex with men (GBMSM). While multiple studies have been conducted on the topic, few have explored the role of trauma in underpinning experiences of SDU among substance use treatment-experienced GBMSM. This qualitative study investigates life histories of trauma, and proposes a framework to better situate the factors driving SDU among treatment-experienced GBMSM.

METHODS

We conducted semi-structured in-depth interviews with 33 purposively-sampled GBMSM with a history of SDU, and seeking treatment for it in Singapore. Interview topics included participants' experiences and life histories of SDU, substance use, incarceration, trauma, as well as stories of resilience and ongoing recovery from SDU. Interviews were audio-recorded, transcribed, coded, and analysed using inductive thematic analysis, from which a trauma-informed framework was developed.

RESULTS

Participants firstly articulated the positive and desired aspects of SDU, such as its utility in allowing them to achieve positive emotional states, sexual enhancement, and feelings of connectedness and intimacy. Participants also described how SDU, in contrast, was used as a coping mechanism to deal with emotional and situational 'precipitants', including dealing with loneliness and a low self-esteem, sexual shame and social anxiety, as well as general stressful situations. Participants also articulated how such precipitants were underpinned by experiences of trauma, including those relating to HIV-related stigma, racism, sexual violence, death and loss, neglect, as well as internalised homophobia. Next, participants illustrated how such trauma were in turn reinforced by several 'preconditions', including the accessibility of substances, emphasis on sexual capital, and lack of access to mainstream support structures in the gay male community, alongside general sociolegal barriers to accessing care.

CONCLUSIONS

This study proposes the role of trauma and the preconditions underpinning them in motivating SDU among a sample of largely substance use treatment-experienced GBMSM in Singapore. Interventions that provide support for GBMSM seeking treatment for SDU should provide trauma-informed care to address the complex barriers to treatment effectiveness.

Delineating patterns of sexualized substance use and its association with sexual and mental health outcomes among young gay, bisexual and other men who have sex with men in Singapore: a latent class analysis

BACKGROUND

Young gay, bisexual, and other men who have sex with men (YMSM) are vulnerable to the risks associated with sexualized substance use. This is a novel study in Singapore that aims to classify patterns of sexualized substance use among YMSM, and investigate its association with sexual and mental health outcomes.

METHODS

In this cross-sectional study among 570 YMSM aged 18 to 25 years old, latent class analysis (LCA) conducted to identify classes with similar patterns of sexualized substance use, across which measures of inconsistent condom use, recent STI diagnoses, past suicide ideation and depression severity were compared.

RESULTS

LCA revealed three classes of YMSM based on types of substances ever used in sexualized contexts, which we labelled as 'substance-naive', 'substance-novice', and 'chemsex'. Substance-naive participants (n = 404) had only ever used alcohol, while substance-novice participants (n = 143) were primarily amyl nitrite users with a small proportion who reported using chemsex-related drugs. Chemsex participants (n = 23) comprised individuals who had mostly used such drugs. Those in the chemsex group were more likely to report recent unprotected anal sex with casual partners (aPR = 3.28, 95%CI [1.85, 5.79]), depression severity (aβ = 3.69, 95%CI [0.87, 6.51]) and a history of suicide ideation (aPR = 1.64, 95%CI [1.33, 2.03]).

CONCLUSIONS

Findings of this study highlight how the use of varying substances in sexualized contexts may be classified and characterized by different sexual and mental health outcomes. Health promotion efforts should be differentiated accordingly to address the risks associated with sexualized substance use among YMSM.

Social capital and chemsex initiation in young gay, bisexual, and other men who have sex with men: the pink carpet Y cohort study

Background

Young gay, bisexual, and other men who have sex with men (YMSM) are especially vulnerable to the risks associated with sexualized substance use, or ‘chemsex’. Engaging in chemsex established as a major risk factor for Human Immunodeficiency Virus (HIV) acquisition, and is thus a public health issue of increasing urgency. This paper attempts to explore the association between measures of social capital and patterns of sexualized substance use among a sample of YMSM in Singapore.

Methods

Results of this study were derived from baseline data of the Pink Carpet Y Cohort Study in Singapore, comprising a sample of 570 HIV-negative YMSM aged 18 to 25 years old. Latent class analysis was employed to identify classes with similar patterns of sexualized substance use, and multinomial logistic regression was employed to examine associations between class membership and proxy measures of social capital, including age of sexual debut, bonding and bridging social capital, connectedness to the lesbian, gay, bisexual and transgender community, and outness.

Results

Latent class analysis revealed three classes of YMSM based on their histories of sexualized substance use, which we labelled as ‘alcohol’, ‘poppers’, and ‘chemsex’. Multivariable analyses revealed that participants who were older (aOR = 1.19, p = 0.002) and who identified as gay (aOR = 2.43, p = 0.002) were more likely to be in the poppers class compared to the alcohol class. Participants with a later age of sexual debut were increasingly less likely to be in the poppers (aOR = 0.93, p = 0.039) and chemsex classes (aOR = 0.85, p = 0.018), compared to the alcohol class.

Conclusions

Varying measures of social capital such as an earlier age of exposure to sexual networks may predispose YMSM to greater opportunities for sexualized substance use. Future interventions should target YMSM who become sexually active at an earlier age to reduce the risks associated with sexualized substance use.

The Chemsex ‘Consent Ladder’ in Male Sex Work: Perspectives of Health Providers on Derailment and Empowerment

Sexualized substance use or ‘chemsex’ is a key element in the syndemic of violence and infection in gay, bisexual, and other men who have sex with men. Chemsex is more prolific amongst men who have sex with men but is also associated with high risk behaviours that can negatively impact on health and wellbeing in heterosexual, bisexual men and women, and in homosexual women too. This qualitative study investigated perceptions and experiences of chemsex, motivations, cisgender male sex work, consent, economic exploitation, and ways to address and reduce harms. We conducted semi-structured interviews with health care providers and their clients—including sex workers and their customers (n = 14) between the ages of 28 and 46 years following a purposive sampling strategy. Interview topics included perceptions and experiences of chemsex use, reasons for drug use and chemsex, and proposals to address harms associated with chemsex in the UK. Interviews were audio-recorded, transcribed, coded, and analysed using Grounded Theory. The findings revealed a stepwise process of chemsex use in a ‘ladder of consent’, whereby the process starts with willing participation that is both highly pleasurable and controllable. Sexual polydrug activity often descended in rungs so that lines of consent became blurred, and even broken, resulting in physical detriment and financial exploitation. Strategies for elevation back up the consent ladder also emerged. The findings clarify the conditions of willing participation, the stepwise relationship to exploitation, and the support strategies that help re-empower individuals whose lives get taken over by chemsex, including peer-to-peer support, poly-centres, and smartphone apps to climb back up the consent ladder to improve the health, safety, and social rights of sex workers.

Harm Reduction Practices and Needs in a Belgian Chemsex Context: Findings from a Qualitative Study

Chemsex is a growing public health concern, with little evidence-based care and support available. The aim of this study is to understand current risk reduction practices, and the information and care needs of gay, bisexual, and other men who have sex with men (GBMSM) who engage in chemsex. Between January and March 2020, semi structured in-depth interviews with drug-using GBMSM (n = 20) were conducted. Data were analyzed thematically. The reported preparatory measures were: deliberately scheduling chemsex sessions, and discussing preferences regarding setting and attendees. During the event, a logbook is kept to monitor drugs taken by each participant. People try to take care of each other, but this is often counteracted. Respondents highlighted needs: reliable and easily-accessible information, anonymous medical and psychological healthcare, chemsex-specific care, and a value-neutral safe space to talk about chemsex experiences. Results imply two types of users: planned and impulsive users. Adherence to intended harm reduction practices are complicated by drug effects, peer pressure, and feelings of distrust among users.

Getting Indonesia's HIV epidemic to zero? One size does not fit all

Indonesia has one of the fastest growing HIV epidemics in the world. AIDS related deaths in Indonesia have not fallen and have increased significantly since 2010. HIV infection rates remain high and rising in key affected populations. We provide an on the ground, evidence-based perspective of the challenges Indonesia faces. We discuss what is required to adopt tailored public health approaches that address context specific challenges, confront structural barriers and the heterogeneity of the current evolving HIV epidemic.

Chemsex practice among men who have sex with men (MSM) during social isolation from COVID-19: multicentric online survey

The aim of this study was to investigate factors associated with sex practice under the effect of drugs (chemsex) among men who have sex with men (MSM) during the period of social isolation in the context of the COVID-19 pandemic. A multicenter online survey was applied to Brazil and Portugal in April 2020 when the two countries were under restrictive health measures due to the pandemic. Participants were recruited with an adaptation of the respondent driven sampling (RDS) method in the online environment. Data were collected using social networks and dating apps for MSM. We used bivariate and multivariate logistic regression to produce crude (OR) and adjusted odds ratios (aOR). In a universe of 2,361 subjects, 920 (38.9%) reported engaging in chemsex practice, which involved casual partners in 95% of the cases. Higher OR of engaging in chemsex were associated with Brazil (aOR = 15.4; 95%CI: 10.7-22.1), not being in social isolation (aOR = 4.9; 95%CI: 2.2-10.9), engaging in casual sex during social distancing (aOR = 52.4; 95%CI: 33.8-81.4), group sex (aOR = 2.9; 95%CI: 2.0-4.4), not presenting any symptom of COVID-19 (aOR = 1.3; 95%CI: 1.1-1.8), not living with the sex partner (aOR = 1.8; 95%CI: 1.2-2.6), and using pre-exposure prophylaxis (aOR = 2.6; 95%CI: 1.8-3.7). The occurrence of chemsex was high, especially in Brazil, where the proposed social distancing did not gain adherence by MSM.

Digital chemsex support and care: The potential of just-in-time adaptive interventions

Chemsex among gay, bisexual and other men who have sex with men (GBMSM) has received increasing attention as a public health concern in recent years. Chemsex can affect a variety of aspects of the lives of GBMSM and contribute to physical, social and emotional health burden. Starting from a continuum perspective of chemsex, rather than a binary view of problematic vs. non-problematic use, we argue that men engaging in chemsex at different points in their chemsex journey may benefit from tailored and personalized support to cope with the various and evolving challenges and concerns that may be related to their chemsex behavior. To date, interactive digital communication technologies are not much used to provide support and care for GBMSM engaging in chemsex, neither for community-based support and care nor by health services. This suggests potential for missed opportunities, as GBMSM are generally avid users of these technologies for social connections and hookups, including in relation to chemsex. Recent research has provided emerging evidence of the potential effects of so-called just in time adaptive interventions (JITAI) to provide effective support and care for a variety of health issues. JITAI hold much promise for the provision of appropriate, tailored support and care for GBMSM at different points in the chemsex journey. Co-designing JITAI with potential users and other stakeholders (co-design) is key to success. At the Institute for Tropical Medicine, in Antwerp (Belgium), we initiated the Chemified project to develop an innovative digital chemsex support and care tool for GBMSM. This project illustrates how current understanding of chemsex as a journey can be integrated with a JITAI approach and make use of co-design principles to advance the available support and care for GBMSM engaging in chemsex.

Influence of Social Media on Sexualized Drug Use and Chemsex Among Chinese Men Who Have Sex With Men: Observational Prospective Cohort Study

Background

Sexualized drug use (SDU; the use of any psychoactive substance before or during sexual intercourse) is prevalent among men who have sex with men (MSM) and may aggravate the worsening HIV epidemic in this key population.

Objective

This observational prospective cohort study investigated factors predicting the occurrence of SDU within a 6-month follow-up period among a sample of MSM in Hong Kong. We hypothesized that perceptions related to SDU would mediate the association between the influence of social media/gay social networking apps and SDU during the follow-up period.

Methods

Participants were Chinese-speaking men in Hong Kong, China who had anal intercourse with at least one man in the past year. Among 600 participants who completed the baseline telephone survey, 407 (67.8%) completed another telephone survey 6 months later. Logistic regression models and path analysis were fitted.

Results

At Month 6, 6.9% (28/407) and 4.4% (18/407) of participants reported SDU and chemsex during the follow-up period. After adjustment for significant baseline background variables (use of pre-exposure prophylaxis; history of HIV and other sexually transmitted infections; anal intercourse with nonregular male sex partners, condomless anal intercourse with men, multiple male sex partnerships, and SDU at baseline), three constructs of the Theory of Planned Behavior (TPB) were significantly associated with SDU during the follow-up period: (1) positive attitudes toward SDU (adjusted odds ratio [AOR] 1.19, 95% CI 1.05-1.36), (2) perceived support for SDU from significant others (AOR 1.15, 95% CI 1.01-1.30), and (3) perceived behavioral control of refraining from SDU (AOR 0.76, 95% CI 0.59-0.98). Exposure to information supporting SDU on social media and gay social networking apps was also significantly associated with SDU (AOR 1.11, 95% CI 1.01-1.22). Bootstrapping analyses indicated that social media influence was indirectly associated with SDU through TPB-related perceptions of SDU (β=.04; B=.002, 95% CI 0.001-0.01).

Conclusions

Social media and gay social networking apps may be a major source of influence on MSM’s perceptions and actual behaviors related to SDU.

Attitude and beliefs about the social environment associated with chemsex among MSM visiting STI clinics in the Netherlands: An observational study

BACKGROUND

Drug use during sex, 'chemsex', is common among men who have sex with men (MSM) and related to sexual and mental health harms. This study assessed associations between chemsex and a wide range of determinants among MSM visiting STI clinics to increase understanding of characteristics and beliefs of MSM practicing chemsex.

METHODS

In 2018, 785 MSM were recruited at nine Dutch STI clinics; 368 (47%) fully completed the online questionnaire. All participants reported to have had sex in the past six months. Chemsex was defined as using cocaine, crystal meth, designer drugs, GHB/GBL, ketamine, speed or XTC/MDMA during sex in the past six months. Associations between chemsex and psychosocial determinants, socio-demographics, sexual behaviour and using tobacco or alcohol were assessed by multivariable logistic regression analyses.

RESULTS

Chemsex was reported by 44% of MSM (161/368) and was not associated with socio-demographics. Independent determinants were 'believing that the majority of friends/sex partners use drugs during sex' (descriptive norm) (aOR: 1.95, 95%CI: 1.43-2.65), 'believing that sex is more fun when using drugs' (attitude) (aOR: 2.06, 95%CI: 1.50-2.84), using tobacco (aOR: 2.65, 95%CI: 1.32-5.32), multiple sex partners (aOR: 2.69, 95%CI: 1.21-6.00), group sex (aOR: 4.65, 95%CI: 1.54-14.05) and using online dating platforms (aOR: 2.73, 95%CI: 1.13-6.62).

CONCLUSION

MSM are likely to find themselves in distinct social networks where it is the norm to use drugs when having sex and pleasure is linked to chemsex. Health services should acknowledge the social influence and pleasurable experiences to increase acceptability of strategies aimed at minimizing the possible harms of chemsex.

Chemsex in Moscow: investigation of the phenomenon in a cohort of men who have sex with men hospitalized due to addictive disorders

The present study was designed to investigate the phenomenon of chemsex among Moscow men who have sex with men (MSM) patients who were hospitalized due to various addictive disorders. It was an observational cohort study which included a total of 30 male patients who underwent inpatient treatment at the Moscow Research and Practical Centre on Addictions of the Moscow Department of Healthcare due to various addictive disorders. Data on sociodemographic, sexuality-, sexually transmitted infection- (STI-), and drug use-related characteristics obtained in face-to-face interviews were recorded in all patients. Mean (SD) age of the patients was 24.3 (3.5) years. Mephedrone was the drug most commonly reported as being used for chemsex (over half of cases); it was consumed by 16 patients. Gamma-hydroxybutyric acid/gamma-butyrolactone use was reported by 6.7% of patients; 16.7% of patients preferred cocaine; ketamine use was present only in one patient. Five participants (16.7%) reported the use of other stimulants. Overall, 20% of patients reported their HIV serostatus as positive. Self-reported other STI status was positive in 12 patients (40.0%). Our findings revealed that practicing chemsex among MSM can be considered a trend in Moscow. Our study emphasizes the role of collaborative work of sexologists and addictologists in order to develop and evaluate the interventions.

Destabilising the 'problem' of chemsex: Diversity in settings, relations and practices revealed in Australian gay and bisexual men's crystal methamphetamine use

In Australia, the crystalline form of methamphetamine ("crystal") is a commonly used illicit substance associated with sexual activity among gay and bisexual men. Attention to psychoactive substance use among this population is the subject of increasing global concern regarding the intentional and simultaneous combination of sex and drugs, often referred to as "chemsex". While not all gay and bisexual men who use psychoactive substances report problematic use, those who do often become representative of chemsex practices more generally, and the harms they experience become attributable to all men who use drugs for sex. The way in which these practices have been framed over the past few decades contributes to the rise of a narrow set of understandings of chemsex defined by the circumstances and behaviours presumed of drug-enhanced sexual activity. In effect, these understandings now align recognisable combinations of sexual and drug-using practices with assumed correlates of risk. The Crystal, Pleasures and Sex between Men study conducted 88 interviews with gay and bisexual men in four Australian cities between 2017 and 2018. Findings from the project revealed that men used crystal in a variety of settings and relations, which mediated their sexual practices and patterns of use. In looking at the wider context in which practices were associated with the combination of sex and drugs, we identified experiences that the contemporary discourse of chemsex-in its rhetorical proposition of at-risk behaviours and circumstances-may leave out of consideration. Our findings indicate that researchers should remain open to the variability and contingency of settings, relations and practices in gay and bisexual men's different networks when recommending public health responses to their engagement in drug-enhanced sexual activity. Accordingly, we seek to destabilise the definition of chemsex that precludes consideration of the influence of experiences beyond pre-determined risk parameters.

Incorporation of information diffusion model for enhancing analyses in HIV molecular surveillance

Molecular surveillance of infections is essential in monitoring their transmission in the population. In this study, newly diagnosed HIV patients' phylogenetic, clinical and behavioural data were integrated, and an information diffusion model was incorporated in analysing transmission dynamics. A genetic network was constructed from HIV sequences, from which transmission cascades were extracted. From the transmission cascades, CRF01_AE had higher values of information diffusion metrics, including scale, speed and range, than that of B, signifying the distinct transmission patterns of two circulating subtypes in Hong Kong. Patients connected in the network, were more likely male, younger, of main circulating subtypes, to have acquired HIV infection locally, and a higher CD4 level at diagnosis. Genetic connections varied among men who have sex with men (MSM) who used different channels of sex networking and varied in their engagement in risk behaviours. MSM using recreational drugs for sex held positions of greater importance within the network. Significant differences in network metrics were observed among MSM as differentiated by their mobile apps usage patterns, evidencing the impact of social network on transmission networks. The applied model in the presence of consistently collected longitudinal data could enhance HIV molecular epidemiologic surveillance for informing future intervention planning.

Understanding the reasons for using methamphetamine by sexual minority people in Dhaka, Bangladesh

BACKGROUND

Internationally, methamphetamine use is prevalent among males who have sex with males (MSM) and transgender women (hijra), with studies showing its association with risky sexual behaviours leading to HIV transmission. This study aimed to explore the underlying reasons for methamphetamine use among MSM and hijra in Bangladesh.

METHODS

We conducted 30 in-depth interviews with MSM and hijra and six focus groups with MSM, hijra and service providers. Data were thematically analysed using manual data analysis procedures.

FINDING

Reasons cited for using methamphetamine varied across feminized MSM (i.e. kothis), masculine MSM (i.e. panthis), male sex workers and hijra. For sex workers, increased sexual pleasure and consequent ability to take more clients increased their income. For panthis, methamphetamine enhanced feelings of masculinity and sexual prowess. Kothis were able to feel more feminine due to their ability to receive multiple partners each night. For all participants, methamphetamine restored self-esteem and relieved the stress resulting from stigma.

CONCLUSIONS

Findings indicate that reasons for using methamphetamine are not only rooted in the individual's psyche but also grounded in the socio-cultural expectations about masculinities and femininities in Bangladeshi society. Limited knowledge about the complexities concerning methamphetamine use mean that appropriate counselling and treatment services are non-existent in Bangladesh. The study findings can be used to refine national and international harm reduction policies so as to incorporate and address methamphetamine use.
