Sexual patterns and practices among men who have sex with men and transgender women in Thailand: A qualitative assessment

Evaluating the Determinants of Substance Use in LGBTQIA+ Adolescents: A Scoping Review

Background: Research has consistently shown increased drug use among lesbian, gay, bisexual, transgender, intersex, queer/questioning, and asexual (LGBTQIA+) individuals. This is particularly the case among LGBTQIA+ adolescents. Substance use within this vulnerable community can propagate mental health issues, leading to psychiatric disorders, self-harm, and even suicide. Therefore, the objective of this scoping review was to evaluate the determinants of drug use among LGBTQIA+ adolescents. Methods: A comprehensive search of mainly primary research was conducted, using several databases. Peer-reviewed articles published between 2018 and 2023 were included. The scoping review was conducted using the framework outlined by Joanna Briggs Institute (JBI) and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Extension for Scoping Reviews (PRISMA-ScR) statement. Results: A total of 29 articles (including 400,194 participants) were included in the analysis. The articles reported that the main determinants of drug use among LGBTQIA+ adolescents include homelessness, peer-peer interactions, mental health, and protective factors. The articles reported that mental health issues, which were mainly triggered by rejection, were the main determinants of drug use among LGBTQIA+ adolescents. Conclusions: Findings from this scoping review provide relatively reliable evidence that homelessness, mental health, peer-peer interactions, and protective factors are the main determinants of illicit drug use among LGBTQ+ adolescents. Rigorous studies including large sample sizes and systematic reviews are needed to further confirm these findings and assist in developing interventions to combat the unusually high level of drug use among this group.

Perceived Feasibility and Acceptability of HIV Prevention Research With Daily Oral PrEP Among Young Transgender Women (YTGW) Who Sell or Trade Sex in Bangkok and Pattaya, Thailand

Young transgender women (YTGW) who sell or trade sex have among the highest HIV incidence rates in Thailand. Using qualitative methods, we assessed perceived acceptability, feasibility, and optimal design of a combination HIV prevention intervention including PrEP for YTGW. Key informant interviews were conducted during July 2016-July 2018 with 21 YTGW, aged 18-26 years, who sold sex and resided in Bangkok or Pattaya, Thailand. Grounded theory and content analysis were used for data analysis. Most YTGW interviewed reported high interest in HIV prevention research and believed participation in it supported sexual health. However, participants perceived HIV studies as complicated and time-consuming. Regarding PrEP, participants suggested more PrEP options beyond daily oral PrEP and expressed concerns related to perceived side effects of PrEP, including interaction with gender-affirming hormone therapy. Improving PrEP knowledge, being able to self-assess HIV risk, and reducing HIV/PrEP stigma could increase interest in research and PrEP uptake among YTGW.

'You Can Get That Person on ART but You Can't Give Them Back Their Social System': A Qualitative Analysis of Voluntary Assisted Partner Notification for HIV for Marginalised and Vulnerable Populations

Little is known about Voluntary Assisted Partner Notification (VAPN) in groups in sub-Saharan Africa that experience marginalisation, and whether its use is suitable for referral to HIV care pathways. We conducted semi-structured in-depth interviews with purposively selected medical and health professionals (N = 15) regarding their perspectives and experiences with VAPN policy and its implementation. Data were analysed following a Reflexive Thematic Analysis approach. Respondents highlighted the flexibility in VAPN policy implementation and described adjustments made by health workers. Women were seen as vulnerable and lacked access to support against gender-based violence. Men who have sex with men could face exclusion from important social networks. Age-appropriate VAPN assistance was also considered unavailable for sexually active children. Embedding understandings of identity, belonging, and safety into VAPN could address individual priorities and needs. Community support networks, tailored care for children, and family-orientated approaches to HIV notification may overcome issues relating to vulnerability and marginalisation.

Unique HIV Risk Factors and Prevention Needs for Transgender Women and Cisgender Men Who Have Sex with Men in Bangkok, Thailand

Background

Transgender women (TGW) and cisgender men who have sex with men (cis-MSM) are often grouped together as key populations. We evaluated behavioral and other characteristics that may distinguish TGW from cis-MSM in Bangkok, Thailand.

Methods

We enrolled into an 18-month cohort cis-MSM and TGW 18-35 years of age without HIV, who reported anal intercourse plus condomless anal intercourse, multiple partners, transactional sex, and/or sexually transmitted infection. Robust multivariable Poisson regression was used to estimate adjusted prevalence ratios (aPRs) and confidence intervals (95% CIs) for associations with being a TGW. Among TGW, logistic regression with generalized estimating equations was used to estimate adjusted odds ratios (aORs) and 95% CIs for associations with taking hormones and having undergone gender affirmation surgery (GAS).

Results

From 2017 to 2019, 660 cis-MSM and 348 TGW were enrolled. Compared to cis-MSM, TGW were more likely to be attracted to mostly/only men (aPR: 3.79, 95% CI: 1.57-9.13), have a higher monthly income (aPR: 1.25, 95% CI: 1.04-1.50), have lived in their current residence for <1 year (aPR: 1.21, 95% CI: 1.01-1.46), have engaged in sex work (aPR: 1.48, 95% CI: 1.23-1.77), and be less likely to have ever undergone HIV testing (aPR: 0.83, 95% CI: 0.70-0.98). Among TGW, 149 (42.8%) were taking hormones and 33 (9.5%) had undergone GAS. GAS was more common among TGW who ever used methamphetamines (aOR: 1.55, 95% CI: 1.00-2.41) and those >23 years (18-20-year olds aOR: 0.17, 95% CI: 0.05-0.55; 21-23-year olds aOR: 0.36, 95% CI: 0.20-0.65).

Conclusions

TGW and cis-MSM are unique populations; tailored, gender-affirming, differentiated models of HIV prevention and care are necessary to address vulnerabilities specific to each key population.

Assessment of U=U understanding, PrEP awareness, HIV risk behaviours and factors associated with low HIV knowledge among users of Hornet, an online dating application for LGBTQ, in Thailand

BACKGROUND

Over 50% of HIV infections in Thailand annually occur among men who have sex with men (MSM) and transgender women who use online applications to meet their sexual partners. We conducted a cross-sectional study assessing undetectable=untransmittable (U=U) understanding, pre-exposure prophylaxis (PrEP) awareness, sexual behaviours and factors associated with HIV knowledge among users of Hornet in Thailand.

METHODS

From November 2019 to January 2020, a survey was conducted using convenience sampling on Hornet in Thailand. HIV literacy was assessed via 22 questions, and multivariable linear regression was performed.

RESULTS

960 responses were assessed; median age was 34 years, the majority were MSM (80.4%), Thai (83.8%), had at least bachelor's degree (74.9%). Regarding the risk profiles, 39.1% reported inconsistent condom use, 15.0% used amphetamine-type stimulants, 56.9% had not taken PrEP in the last six months and 20.5% never had an HIV test. Only 22.8% thought that U=U was completely accurate. Lower HIV knowledge was associated with being from Africa (β -8.13, 95% CI -14.39 to -1.87), age of 25 years or younger (β -2.6, 95% CI -4.37 to -0.82), education less than bachelor's degree (β -2.58, 95% CI -3.98 to -1.19), having more than one sexual partners (β -2.41, 95% CI -4.13 to -0.69), paying three or more people to have intercourse (β -2.5, 95% CI -4.26 to -0.74), not knowing one's HIV status (β -3.56, 95% CI -5.45 to -1.68) and not answering about previous PrEP use (β -4.11, 95% CI -7.86 to -0.36). Higher HIV knowledge was associated with being from Europe (β 2.54, 95% CI 0.46 to 4.61), the Americas (β 3.37, 95% CI 0.44 to 6.30) and previous PrEP use (β 2.37, 95% CI 0.94 to 3.81).

CONCLUSION

Among Hornet users in Thailand, the U=U message was unclear, and PrEP use was suboptimal. Large HIV knowledge gaps and high-risk behaviours were concerning. Educational campaigns in online spaces are needed to promote awareness and HIV prevention strategies.

Differing Correlates of Incident Bacterial Sexually Transmitted Infections Among a Cohort of Black Cisgender Men Who Have Sex With Men and Transgender Women Recruited in 6 US Cities (HIV Prevention Trials Network 061)

ABSTRACT

Compared with Black cisgender men who have sex with men (MSM), Black transgender women had a higher incidence of bacterial sexually transmitted infections (25.9 [11.1-46.3] vs. 9.6 [8.10-11.3] per 100 person-years), higher rates of income and housing insecurity, and condomless receptive anal intercourse. Further investigation of unique risk pathways among transgender women is critical.

Oral sex practices among men who have sex with men and transgender women at risk for and living with HIV in Nigeria

Background

Men who have sex with men (MSM) and transgender women (TGW) are at risk for sexually transmitted infections (STIs), including those of the oropharynx. We estimated the prevalence and factors associated with oral sex practices and characterized oropharyngeal STIs among a cohort of MSM and TGW in Nigeria.

Methods

From 2013 to 2018, TRUST/RV368 recruited MSM and TGW into HIV/STI diagnosis and treatment at community-based clinics in Nigeria. Participants who completed HIV testing and oral sex questions at enrollment were selected. Cross-sectional analyses with bivariate and multivariable logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs). Oropharyngeal swab testing for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) began in 2014 and for those with diagnostic results at enrollment, the unadjusted association of oral sex practices with oropharyngeal STIs was conducted.

Results

A total of 1342 participants had a median age of 25 years (interquartile range: 22–29), 58% were living with HIV, and 69% reported oral sex practices. Factors associated with increased odds of engaging in oral sex included living with HIV (adjusted [a]OR: 1.4, 95% CI: 1.1–1.8), self-identifying as a woman (aOR:1.8, 95% CI: 1.1–2.8), mobile phone ownership (aOR:2.3, 95% CI: 1.3–3.9), receptive anal sex (aOR:1.7, 95% CI:1.3–2.3) and multiple male sexual partners (2 to 4 vs. ≤1, aOR:1.5, 95% CI: 1.0–2.2; 5+ vs ≤1, aOR:2.9, 95% CI:1.9–4.3). Oropharyngeal STI prevalence was 7% (52/752) and higher among those who engaged in oral sex compared to those who did not (unadjusted OR: 2.5, 95% CI:1.2–5.3).

Conclusions

Oral sex was common and associated with an increased odds of oropharyngeal STIs among MSM and TGW from Nigeria. In the absence of screening and treatment guidelines, condoms continue to be the mainstay for oral STI prevention. A pre-exposure prophylaxis for bacterial STIs would complement current prevention strategies to curb transmission.

Combined effects of gender affirmation and economic hardship on vulnerability to HIV: a qualitative analysis among U.S. adult transgender women

Background

Transgender women (“trans women”), particularly African-American and Latina trans women, have disproportionately high prevalence of HIV in the United States (U.S.). In order to decrease gender dysphoria and overcome discrimination, trans women affirm their gender through social and medical transition, often in contexts of economic hardship and sexual risk. This study qualitatively examined how gender-affirming behaviors enhance or diminish vulnerability to HIV in light of structural and economic barriers to gender transition.

Methods

We conducted individual interviews with 19 adult trans women in two U.S. cities (Richmond, VA and St. Louis, MO) who reported one or more sexual risk behaviors and recent economic hardship related to employment/income, housing, or food security. Interviews were recorded, transcribed, and analyzed using thematic content analysis.

Results

The majority (74%) of trans women were racial/ethnic minorities with mean age of 26.3 years. Gender-affirming behaviors varied with 58% of trans women having legally changed their name and gender marker; 79% having initiated hormone therapy; and 11% having not initiated any medical or legal changes. None had undertaken surgical changes. Findings suggested that the process of gender transitioning resulted in both increasing and decreasing HIV risk. The high need for gender affirmation by male sex partners contributed to trans women’s exposure to sexual objectification, sexual risk behaviors, and conflicting interests in HIV prevention messaging. Loss of housing and employment due to transition along with the high costs of transition products and medical visits increased reliance on sex work and created new obstacles in accessing HIV services. Trans women experienced lower HIV risk as they acquired legal and medical transition services, reshaped interactions with sex partners, and received gender-affirming support by others, including health providers, employers, peers, and housing professionals. Sexual abstinence was viewed as a negative consequence of incomplete transition, although characterized as a period of low HIV risk.

Conclusions

Structural and policy initiatives that promote safe gender transition and economic stability in trans women may play a critical role in reducing HIV in this population. Addressing the harmful pressures for U.S. trans women to conform to perceived feminine stereotypes may also serve an important role.

Discordance between self-perceived and actual risk of HIV infection among men who have sex with men and transgender women in Thailand: a cross-sectional assessment

INTRODUCTION

Low uptake of HIV testing and services, including pre-exposure prophylaxis (PrEP), in Thai men who have sex with men (MSM) and transgender women (TGW) may be due to the inaccuracy in self-risk assessment. This study investigated the discordance between self-perceived HIV risk and actual risk.

METHODS

Data were obtained between May 2015 and October 2016 from MSM and TGW enrolled in key population-led Test and Treat study in six community health centres in Thailand. Eligible participants were at least 18 years old, Thai national, had sex with men, had unprotected sex with a man in the past six months or had at least three male sex partners in the past six months, and were not known to be HIV positive. Baseline demographic behavioural characteristics questionnaires, including self-perceived HIV risk, were self-administered. Participants received HIV/STI (syphilis/gonorrhoea/chlamydia) testing at baseline. Participants who self-perceived to have low risk, but engaged in HIV-susceptible practices were categorized as having risk discordance (RD). Regression was conducted to assess factors associated with RD among MSM and TGW separately.

RESULTS

Of the 882 MSM and 406 TGW participants who perceived themselves as having low HIV risk, over 80% reported at least one of the following: tested HIV positive, engaged in condomless sex, tested positive for a sexually transmitted infection sexually transmitted infection (STI; or used amphetamine-type stimulants. Logistic regression found that living with a male partner (p = 0.005), having never tested for HIV (p = 0.045), and living in Bangkok (p = 0.01) and Chiang Mai (p < 0.001) were associated with increased risk discordance among MSM. Living with a male partner (p = 0.002), being less than 17 years old at sexual debut (p = 0.001), and having a low knowledge score about HIV transmission (p < 0.001) were associated with increased risk discordance among TGW. However, for TGW, being a sex worker decreased the chance of risk discordance (p = 0.034).

CONCLUSIONS

Future HIV prevention messages need to fill in the gap between self-perceived risk and actual risk in order to help HIV-vulnerable populations understand their risk better and proactively seek HIV prevention services.
