Partying in Thailand: Never Testing Among Men Who Have Sex With Men Who Attend Sexualized (Drug) Parties.

BACKGROUND: Human immunodeficiency virus (HIV) testing for Thai men who have sex with men (MSM) is suboptimal, which undermines their linkage to care and subsequent HIV preexposure prophylaxis (PrEP) uptake. METHODS: We analyzed a cross-sectional survey conducted in 2021 among Thai MSM who attended any private sex parties or circuit parties in the past 3 years ("sexualized parties"). RESULTS: Of the 424 men included in our analysis, 47.6% had been recently tested for HIV in the past 1 year, 30.2% had not recently been tested, and 22.2% had never been tested. In our multivariable analysis, relative to participants who had recently tested for HIV, those who have never tested were more likely to have lower education or to live outside of Bangkok, and to have attended both circuit and private sex parties (vs. private sex party only) but were less likely to report any sexually transmitted infection diagnosis or to have heard of PrEP. Participants who had an HIV test more than a year ago were more likely to have attended both circuit and private sex parties (vs. private sex parties only) but were less likely to have any sexually transmitted infection diagnosis, meet sexual partners online, or have heard of PrEP. Rates of condomless anal sex and willingness to use PrEP were similar across groups. CONCLUSIONS: Despite the high rates of sexual risk-taking, sexualized party attendees reported suboptimal HIV testing uptake. The joint promotion of HIV testing and PrEP is warranted-especially on-premise HIV testing at circuit parties and outreach at online platforms to reach sexualized party attendees.

Sexual orientation disclosure and depression among Thai gay, bisexual, and other men who have sex with men: The roles of social support and intimate partner violence.

BACKGROUND: Among gay, bisexual, and other men who have sex with men (GBM), sexual orientation disclosure to social groups can act as a significant risk for depression. The primary goal of this research is to understand the association between disclosure and depression, the association of social support and intimate partner violence (IPV) experiences, depression, and disclosure. METHODS: This project uses a secondary dataset of Thailand from a larger cross-sectional study distributed in the Greater Mekong Sub-Region. This study utilized web-based answers from 1468 Thai GBM respondents between the ages of 15-24 years. RESULTS: Prevalence of depression was over 50%. Across the social groups of interest, those who disclosed to everyone had the lowest depression prevalence. This association was statistically significant for all groups (p<0.050) except for "Family members" (p = 0.052). There was a statistically significant association illustrated between full disclosure to social groups and increased social support. Most respondents (43.9%) had low social support, and additionally this group had the highest level of depression, compared to those with high social support. There was a statistically significant association for lowered depression outcomes and increased social support. IPV experiences that occurred within the last six months had a statistically significant relationship with depression (p = 0.002). There was a notable association between those with experiences of being a victim of IPV, alone and in conjunction with experience of being a perpetrator of IPV, which was associated with increased odds of depression. However, the type of IPV experiences an individual had did not differ based on disclosure status. DISCUSSION: This study provides strengthened evidence of the impact that differences in supportive networks can have on mental health outcomes. In addition, they provided a wider consideration for how people may have different IPV experiences, either as a perpetrator, victim, or both, and how those shapes health outcomes of depression. GBM communities still face adversity and challenges that affect their long-term health outcomes, even if they do live in what is considered an accepting country.

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.

Early maladaptive schemas and addictive behaviours: A systematic review and meta-analysis.

BACKGROUND: Recently, early maladaptive schemas have been increasingly focused as the underlying factor of several psychopathologies. The primary objective is to systematically review and meta-analytically analyse the evidence on the relationship between early maladaptive schemas and types of addictive behaviours. Additionally, the secondary objective was to examine potential moderators of the effect sizes. METHODS: The systematic search was conducted on three databases including 'Scopus', 'Web of Science' and 'PubMed'. They were searched for quantitative studies investigating the relationship between early maladaptive schemas and addictive behaviours. The studies that were non-English and had insufficient information to calculate effect sizes were excluded. The random-effect model was utilized to estimate the pool effect sizes, and the meta-regression was used for moderation analysis. RESULTS: Thirty-three studies with 12,577 participants were included for analyses. Most of included studies were conducted in the United States (k = 12, 36.36%). The mean ages of participants varied from 13.32 to 46.09 years. The findings indicated that all of early maladaptive schemas and schema domains positively correlated with addictive behaviours. The disconnection and rejection, impaired limits and impaired autonomy were the domains with the highest association with substance addictions (pool r = 0.338, 3.26 and 3.16, respectively). Furthermore, disconnection and rejection and impaired autonomy were the schema domains with the highest association with behavioural addictions (0.310 and 0.304, respectively). The moderation analysis demonstrated that study design was the factor affecting the effect sizes between schema domain and addictive behaviours. LIMITATION: All included studies were from peer-reviewed journals in English. Moreover, the number of research examining the relationship between early maladaptive schemas and behavioural addictions was limited. CONCLUSION: The findings provide evidence supporting the idea that substance addictions and behavioural addictions have shared risk factors, supporting the validity of the schema model, which can be applied for targeting and preventing addictive behaviours.

The Moderating Role of Social Support and HIV Stigma on the Association Between Depression and ART Adherence Among Young Thai Men Who Have Sex with Men.

In Thailand, antiretroviral therapy (ART) programs still have difficulties reaching and promoting adherence among a key population - young men who have sex with men (YMSM) living with HIV. As such, we sought to examine potential psychosocial barriers that may contribute to suboptimal levels of ART adherence for this population. Data were drawn from a study of 214 YMSM living with HIV from Bangkok, Thailand. Linear regression models tested the association between depression and ART adherence, and whether social support and HIV-related stigma moderated that relationship. Multivariable models demonstrated social support was significantly associated with higher levels of ART adherence, and that there was a three-way interaction between depression, social support, and HIV-related stigma on ART adherence. These results further our understanding of the role of depression, stigma, and social support in ART adherence among Thai YMSM living with HIV, and that additional supports for YMSM with depression and HIV-related stigma are needed.

Chemsex and chemsex associated substance use among men who have sex with men in Asia: A systematic review and meta-analysis.

BACKGROUND: The prevalence of chemsex has been reported by multiple systematic reviews among men who have sex with men (MSM) focussing predominantly on the Global North. An Asian perspective with meta-analytical evidence is missing. This meta-analysis summarised the prevalence of substance use associated with chemsex, and chemsex activity among MSM and MSM sub-populations in Asia, as well as the likelihood for chemsex among MSM living with or without HIV. METHODS: We utilized PubMed, Web of Science and medRxiv to search for literature describing chemsex and its associated substance use among MSM and MSM sub-populations in Asia from January 1, 2010 to November 1, 2021 to conduct three meta-analyses with both frequentist and Bayesian approaches. RESULTS: We identified 219 studies and included 23 in the meta-analysis. Based on the frequentist models, methamphetamine was the default substance associated with chemsex among MSM in Asia (prevalence = 0.16, 95 %CI:0.09-0.22), followed by GHB/GBL (prevalence = 0.15, 95 %CI:0.03-0.27) and ketamine (prevalence = 0.08, 95 %CI:0.04-0.12), but hardly any cocaine (prevalence = 0.01, 95 %CI:0.00-0.03). Compared to a general MSM population (prevalence = 0.19, 95 %CI:0.15-0.23), MSM engaging in transactional sex showed a higher prevalence of chemsex (MSM sex work clients [prevalence = 0.28, 95 %CI:0.11-0.45]; MSM sex worker [prevalence = 0.28, 95 %CI:0.17-0.26]). MSM living with HIV also showed higher odds of chemsex activity (OR = 3.35, 95 %CI:1.57-7.10), compared to MSM living without HIV. Both meta-analytic models converged, indicating robust evidence. CONCLUSIONS: Our meta-analyses showed that chemsex is not uncommon among MSM, and MSM engaging in transactional sex in Asia. We confirmed that MSM living with HIV have a higher likelihood of engaging in chemsex, too. Chemsex prevention and management strategies in Asia should be adjusted accordingly.

Effects of intimate partner violence and homophobic bullying on ART adherence among young Thai men who have sex with men: a causal mediation analysis.

Background: Adherence to antiretroviral therapy is crucial in determining health outcomes and secondary HIV transmission for people living with HIV/AIDS. Young men who have sex with men (YMSM) living with HIV are often challenged by the prevailing experiences of psychosocial stressors, such as intimate partner violence and homophobic bullying, which may negatively affect their HIV care engagement. Methods: This study is the first to utilize a prospective cohort design (N= 185) involving YMSM living with HIV in Thailand. We examined the effects of intimate partner violence and homophobic bullying on ART adherence. We also tested the mediating effect of depression on the relationship between intimate partner violence and homophobic bullying on ART adherence. Results: We found that intimate partner violence (AOR: 2.58, 95% CI: 1.13, 5.42) and homophobic bullying (AOR: 2.40, 95% CI: 1.26, 4.48) were associated with subsequent ART nonadherence. Moreover, depression partially mediated 17.4% (95% CI: 0.75%, 56%) of the effect of homophobic bullying on ART nonadherence. Conclusions: The results suggest that tailored interventions to optimize ART adherence should address the impacts of intimate partner violence and homophobic bullying for HIV+ YMSM. The screening and subsequent treatment of depression alone may not be sufficient to address the effects of intimate partner violence, homophobic bullying, and possibly other MSM-specific psychosocial stressors on ART adherence.

Pride-based violence, intoxicated sex and poly-drug use: a vocational school-based study of heterosexual and LGBT students in Bangkok.

BACKGROUND: In Thailand, drug use is widely observed, especially among vocational-school students, who are more inclined to use various types of drugs and to experience pride-based violence (violence based on institutional pride, honor, or on seniority status) than any other groups of students. Drug use contexts differ based on sexual orientation and gender identity (e.g., clubs). This study aims to examine the prevalence and correlates of poly-drug use (the use of at least three types of drugs) among vocational-school students, with a focus on sexual orientation and gender identity. METHODS: In this study, 638 vocational school students living in Bangkok metropolitan area participated in a three-year longitudinal survey of four vocational schools. Experiences of violence, sexual behaviours, and poly-drug use were assessed and analyzed using multivariable logistic regression. RESULTS: About one tenth of all students (11.3%) reported poly-drug use, a fifth among Lesbian, Gay, Bisexual and Transgender (LGBT) students (20.2%) and almost a tenth of heterosexual students (9.8%). In the multivariable logistic model of LGBT students, GPA, pride-based violence, intoxicated sex, and counseling needs were significantly associated with poly-drug use (AOR = 4.62; 95% CI 1.17-18.29, AOR = 6.01; 95% CI 1.31-27.32, AOR = 5.17; 95% CI 1.10-24.28, AOR = 4.64; 95% CI 1.16-18.54, respectively). Likewise, among heterosexual students, GPA and intoxicated sex were significantly associated with poly-drug use (AOR = 2.02; 95% CI 1.09-3.75, AOR = 5.31; 95% CI 2.81-10.04, respectively). CONCLUSIONS: LGBT vocational-school students have significantly higher prevalence of poly-drug use than their heterosexual peers. Correlates include lower GPA, having experienced pride-based violence and intoxicated sex. School-based intervention programs should also address pride-based violence and intoxicated sex in their harm reduction programs.

HIV prevalence and incidence among men who have sex with men and transgender women in Bangkok, 2014-2018: Outcomes of a consensus development initiative.

To reach its goal of ending AIDS by 2030, Thailand has adopted antiretroviral treatment as prevention and HIV pre-exposure prophylaxis for men who have sex with men (MSM) and transgender women (TGW) as its core HIV control strategy. However, in the absence of reliable epidemiologic indicators, the impact of these policies on the course of the HIV epidemic in these groups remains unknown. To help answer this question, we formulated an HIV epidemic consensus initiative for Bangkok, Thailand, to analyze epidemiologic and program data and reach agreement between experts and stakeholders on the evolving state of the HIV epidemic among MSM and TGW. A customized Delphi process was used to consult and consolidate viewpoints of experts and stakeholders. Experts presented and discussed HIV prevalence and incidence data from recent and ongoing studies among MSM and TGW in Bangkok (2014 to 2018) during a meeting with stakeholders representing government, donors, and civil society. Agreement about the course of the HIV epidemic among MSM and TGW was attained by voting consensus. Based on presented data, meeting participants agreed that HIV prevalence and incidence had decreased among Bangkok MSM from 2014 to 2018. Despite these declines, HIV prevalence and incidence were found to remain high. This was particularly the case among younger MSM. Participants agreed that there was no evidence for a decrease in HIV prevalence and incidence among Bangkok TGW. Introduction of antiretroviral treatment as prevention and HIV pre-exposure prophylaxis may have contributed to these declines. However, HIV prevalence and incidence remained high, and no signs of a decrease were reported among Bangkok TGW. At the current rate of new HIV infections in MSM and TGW, Thailand will not reach its goal of ending AIDS by 2030. This HIV consensus initiative may serve as a model for building agreement and advocacy on epidemiologic and program data and their implications for a large metropolitan city.

Bridging the serodivide: attitudes of PrEP users towards sex partners living with HIV.

The introduction of biomedical HIV prevention methods, such as pre-exposure prophylaxis (PrEP), holds the potential to overcome the serodivide. We investigated the attitudes of PrEP users towards having sex with partners living with HIV. PrEP users in the Netherlands were recruited online and completed three questionnaires over a period of six months. We investigated changes over time in feelings of fear of HIV, comfort, and attitudes towards condom use when having sex with men living with HIV (MLHIV). A majority of PrEP users in our sample (up to 71.6%) had sex with MLHIV. Feeling comfortable to have sex with MLHIV did not change over time, but was already at a high level at T1. Most importantly, feeling safe not to use condoms with HIV-positive partners significantly increased, and did so in a rather short period of time after the onset of PrEP use (3-6 months). Taken together, the findings suggest that that PrEP may contribute to decreasing the serodivide between MSM rather quickly after the onset of PrEP use.

Quality of Sex Life and Perceived Sexual Pleasure of PrEP Users in the Netherlands.

Next to its benefits for HIV prevention, PrEP may have psychosocial benefits relating to improved quality of sex life. The aim of the current study was to investigate the onset of changes in the quality of sex life and sexual pleasure of PrEP users in the first months of commencing PrEP use. Moreover, we investigated what factors were related to the quality of sex life of PrEP users. We recruited 145 participants via the Dutch PrEP-advocacy website PrEPnu.nl, and they received follow-up questionnaires after three and six months. We found that PrEP users reported an increase in the quality of their sex life, which was related to reduced fear of HIV since they started using PrEP but not to decreased condom use. PrEP users were more interested in experimenting with sex practices, but they did not always feel more desirable as a sex partner because of PrEP use. Health-care providers and health promotion campaigns could emphasize the positive effects of PrEP on the quality of sex life, in addition to the HIV-preventive effects of PrEP, to decrease PrEP stigma and increase PrEP uptake.

"Kids these days pretend to be grownups" (dekkaedaet): sexual control and negotiation among young Thai female students.

BACKGROUND: Young Thai women are growing up amidst conflicting influences of globalization and traditional Thai culture. They experience confusion about which aspects of their sexuality they can express and must hide. This study examined forms of sexual control and sexual negotiation among young Thai women in secondary and vocational schools. METHODS: Semi-structured interviews and focus group discussions were conducted among 13-to 18-year-old female students attending secondary and vocational schools in six regions of Thailand. Additional semi-structured interviews were conducted with instructors of sex education, school administrators, and parents of students. NVIVO 10 was used to manage, code and assist with data analysis. RESULTS: Socio-cultural control on young women's sexualities was found from members of their families, schools, communities, and other students. Young women expressing their sexualities openly through verbal expressions, clothing, and behaviors were deemed negatively and stigmatized as dekkaedaet or "kids pretending to be grownups" as it is believed that they are too young and too immature to be responsible for their own decisions on their bodies and sexuality. This dominant discourse subsequently stigmatize and embarrass sexually active women. However, some young women try to negotiate and create options, by utilizing strategies that ensure secrecy. CONCLUSION: Comprehensive sexuality education is needed and should be based on the respect for human dignity and sexual and reproductive rights.

Correlates of newly diagnosed HIV infection among cisgender women sex workers and transgender women sex workers in Greater Kuala Lumpur, Malaysia.

Globally, cisgender women sex workers (CWSWs) and transgender women sex workers (TWSWs) experience increased vulnerabilities to HIV infection. Unfortunately, there is limited data on the drivers of HIV infection in these two understudied populations, particularly in Southeast Asia. To better understand factors associated with HIV infection, we evaluated correlates of newly diagnosed HIV infection in these two populations in Greater Kuala Lumpur, Malaysia. A total of 469 women (CWSW: n = 283; TWSW: n = 186) were included in this study. Most participants who tested HIV+ were unaware of their infection (59.6%; n = 34/57). Separate binary and multivariable logistic regressions were conducted to identify correlates of newly diagnosed HIV in CWSWs and TWSWs. Among CWSWs, Chlamydia trachomatis (aOR = 5.66; p = 0.007) and lifetime use of ecstasy/MDMA (aOR = 5.34; p = 0.03) were associated with newly diagnosed HIV, while condomless vaginal sex with clients was associated with lower likelihood of HIV infection (aOR = 0.98; p = 0.01). Among TWSWs, being single (aOR = 6.76; p = 0.03), using mobile application to solicit clients (aOR = 25.33; p = 0.006), and having C. trachomatis infection (aOR = 88.22, p = 0.02) were associated with newly diagnosed HIV. Expansion of HIV/sexually transmitted infection screening is needed to increase detection of HIV and linkage to care for sex workers. Interventions to reduce HIV infection among CWSWs and TWSWs should be tailored to these populations' unique vulnerabilities.

Slow Uptake of PrEP: Behavioral Predictors and the Influence of Price on PrEP Uptake Among MSM with a High Interest in PrEP.

Despite the improved availability and affordability of PrEP in the Netherlands, PrEP uptake is low among men who have sex with men (MSM). To optimize uptake, it is important to identify facilitators and barriers of PrEP use. During our study period, the price of PrEP dropped significantly after generic PrEP was introduced. We investigated whether the price drop predicts PrEP uptake, alongside behavioral and demographic characteristics. Participants (N = 349) were recruited online and completed three questionnaires over a period of 6 months, between February 2017 and March 2019. After 6 months, 159 (45.6%) participants were using PrEP. PrEP uptake was greater among MSM who ever had postexposure prophylaxis (PEP) treatment, among MSM with a better perceived financial situation, and when the price of PrEP dropped. MSM in a tighter perceived financial situation may use PrEP more when it would be free or fully reimbursed.

RESUMEN: A pesar de la disponibilidad y asequibilidad a PrEP en Los Paises Bajos, el consumo de PrEP es bajo entre hombres que tienen sexo con hombres (HSH). Para optimizar su consumo, es importante identificar los factores facilitadores y las barreras del uso de PrEP. Durante nuestro estudio, el precio de PrEP se redujo significativamente, después de que se introdujo la PrEP genérica al mercado. Investigamos las características demograficas y de conducta y si la caída en el precio predice el consumo de PrEP. Participantes (N = 349) fueron reclutados en linea y completaron tres cuestionarios en un periodo de seis meses, entre Febrero de 2017 y Marzo de 2019. Despues de seis meses, 159 participantes (45.6%) estaban usando PrEP. El consumo de PrEP fue mayor cuando el precio de PrEP bajó y entre HSH que se sometieron a un tratamiento de profilaxis posexposición (PEP) y que tenían una buena situación financiera. HSH con una percibida situacion finaciera más precaria podrían usar PrEP más cuando sea gratis o reembolsada totalmente.

Willingness to Use HIV Self-Testing With Online Supervision Among App-Using Young Men Who Have Sex With Men in Bangkok.

ABSTRACT: An online assessment among social media-using young men who have sex with men found that 87% were willing to use HIV self-testing with online supervision. Correlates included never tested, having higher numbers of sexual partners, and seeking partners online. HIV self-testing with online supervision may be appropriate for young men who have sex with men who have high risks and may not access venue-based settings.

Socio-Sexual Experiences and Access to Healthcare Among Informal PrEP Users in the Netherlands.

The aim of this qualitative study was to explore the experiences of informal PrEP users regarding access to PrEP and PrEP-related healthcare, community responses, sexual behavior and well-being. We interviewed 30 men who have sex with men (MSM) in semi-structured online interviews between March and August 2018. Interviews were analyzed using interpretive description. Informal PrEP users were well informed about the use of PrEP, but sometimes did not make use of renal testing. Participants reported a lack of PrEP knowledge among healthcare providers, which limited their access to PrEP and put them at risk, as they received incorrect information. Although some participants reported negative reactions from potential sex partners, most received positive reactions and were sometimes seen as more desirable sex partners. PrEP healthcare services should not only be accessible to formal PrEP users, but also to PrEP users who procure PrEP informally.

Willingness to Use HIV Self-Testing and Associated Factors Among Transgender Women in Malaysia.

Background: While global research on the implementation of HIV self-testing (HIVST) has increased exponentially, few studies have assessed information on HIVST uptake factors (i.e., willingness, preferences) in transgender women (TW) and none in the Malaysian context. We therefore sought to assess willingness to use HIVST among this understudied key population. Methods: A cross-sectional survey was conducted among 361 HIV-negative Malaysian TW in 2017. Participants were recruited using flyers, announcements through social media, and direct referral from staff members of the community-based organizations serving the TW communities. Multivariable logistic regression was used to identify correlates of willingness to use HIVST. Results: Nearly half of the participants (47.6%) reported that they would be willing to use HIVST. Multivariable analysis showed that willingness to use HIVST was positively associated with having experienced sexual assault in childhood (adjusted odds ratio [aOR]=3.239, p<0.001), having ever used mobile phone or apps to find sex work clients (aOR=1.677, p=0.040), and having engaged in condomless sex in the past 6 months (aOR=1.886, p=0.018). In contrast, living in Kuala Lumpur (aOR=0.559, p=0.032), having higher number of sex work clients per day (aOR=0.927, p=0.004), and current depressive symptoms (aOR=0.576, p=0.026) were negatively associated with willingness to use HIVST. Conclusions: Findings in this study suggest that TW in our sample were moderately willing to use HIVST. Especially important here is the increased interest in HIVST among TW who are at higher risk for HIV infection. Overall, our findings underscore the need for additional research on how to most effectively implement HIVST for key populations, including TW, such that uptake and retention in regular HIV screening is sustained.

Social violence among Thai gender role conforming and non-conforming secondary school students: Types, prevalence and correlates.

BACKGROUND: Gender role non-conforming behaviors are a significant risk factor for school-related violence. The objective of this study is to describe the types, prevalence and correlates of social violence among Thai secondary school students, with a focus on gender role non-conformity. METHODS: This article uses secondary data from a national study of 2070 secondary school students aged 13-20 years representing Bangkok and all four regions of Thailand. Students were asked about their gender/sexual identity, self-perception of their masculinity or femininity, and experiences of social violence. Correlates of social violence were examined using multivariable logistic regression models. RESULTS: Prevalence of social violence victimization was high (57%). Most students considered themselves to be as masculine or as feminine as other members of their sex (82.6%), while 9.1% thought that they were less masculine/less feminine, and 8.3% thought they were more masculine/more feminine. Students who considered themselves less masculine or less feminine than others of their sex (AOR = 1.59, 95% CI: 1.13, 2.25) were more likely to experience social violence, compared to students who considered themselves equally masculine/feminine. Students who self-identified as lesbian, gay, bisexual or transgender (LGBT) (AOR = 1.37, 95% CI: 1.01, 1.86) were also more likely to experience social violence, compared to students who did not identify as LGBT. However, students who considered themselves more masculine or feminine than other students of their sex (AOR = 0.62, 95% CI: 0.44, 0.88) were less likely to experience social violence. DISCUSSION: Students who identified as LGBT, or considered themselves to be less masculine or less feminine than other students of their sex, had higher odds of social violence victimization. Anti-bullying campaigns need to emphasize that perpetrating social violence is not tolerated, and gender-based violence needs to be included in comprehensive sexuality education curricula.

Peer victimisation and depression among gender conforming and non-conforming Thai adolescents.

Like most low- and middle-income countries, Thailand is facing an increasing burden of depressive disorders among adolescents, but research and services for them are largely neglected. This study explored the association between types of peer victimisation, gender non-conformity, health risk behaviours, and depressive symptoms among Thai students aged 13-18 years. Overall, prevalence of depressive symptoms was 14.7% (95% CI: 12.6-15.6), 12.2% (95% CI: 9.5-13.9) among male students and 16.5% (95% CI: 13.8-18.0) among female students. Among both sexes, social and sexual victimisation in the past month were strongly associated with depressive symptoms in the past week. Gender non-conforming female adolescents, as well as male and female adolescents who had experienced sexual and social victimisation, had a high burden of depressive symptoms. Mental health professionals and educators working with young people in Thailand should consider assessment for clinically significant depressive disorders.
