Sexualized substance use or "chemsex" may contribute to the HIV epidemic among men who have sex with men (MSM) in Thailand. Specific patterns of chemsex use may be associated with different HIV/STI transmission risks. We examined typologies and correlates of sexualized substance use among a sample of high-risk MSM (n = 532) who had attended a private sex party or circuit party in the past three years using latent class analysis. Multinomial regression was used to adjust for variables associated with the 3-class latent class model. We identified a 3-class model as the best fitting model, which included: (1) "negligible sexualized substance users" (36.7%), who had never engaged in chemsex in the past six months; (2) "sexualized substance users" (13.9%), who had a high level of sexualized alcohol use and a wide range of other substances before or during sex in the past six months; and (3) "exclusive chemsex users" (49.4%), who predominantly used crystal methamphetamine, amyl nitrite, and erectile dysfunctional drugs before or during sex in the past six months. Compared to negligible sexualized substance users, exclusive chemsex users were more likely to be HIV-positive, more likely to have six or more sexual partners in the past six months, less likely to have condom use at last anal intercourse, and more likely to have provided sex work. Relative to negligible sexualized substance users, sexualized substance users reported more frequent online sex-seeking behaviors. These subgroups of Thai MSM have unique substance use patterns and HIV-related risk profiles, underscoring the importance of targeted HIV prevention strategies. [ABSTRACT FROM AUTHOR]

This qualitative study focuses on youth perceptions of cyberbullying (definition, causes, consequences, and management). We also articulate how perceptions of cyberbullying among Thai youth are influenced by Thai culture, including Thai youth culture. Data were collected from 15 to 24 year-olds in Central Thailand through 22 focus group discussions (FGDs) with 4-6 participants each, as well as 26 in-depth interviews (IDIs), totaling 136 participants. These youth defined cyberbullying as harming others through mobile phones and the Internet. To count as cyberbullying, actions had to cause real harm or annoyance and be committed with malicious intent. The relationship between the parties involved also mattered: close friends were unlikely to be considered cyberbullies. Participants thought that the anonymity of cyberspace is a key cause of cyberbullying but also that cyberbullying often results from previous offline incidents of violence. In their view, cyberbullying impacts individuals and their social interactions. Participants tended to manage the problem by themselves and not consult their parents. Alarmingly, participants viewed cyberbullying as 'an ordinary matter'. To raise awareness that cyberbullying is a societal problem with serious consequences, state agencies and educational institutions need to play active roles in preventing it and responding to it constructively when it occurs.

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., Competing Interests: Conflict of Interest and Sources of Funding: The authors declare that they have no conflict of interest.

The term "Pre-exposure prophylaxis (PrEP) tourists" refers to individuals who obtain PrEP in other countries and use it in their home countries. A prospective observational cohort study was conducted among a group of men who have sex with men (MSM) who obtained PrEP in private clinics in Thailand and used it in Hong Kong. Participants completed two web-based self-administered surveys when obtaining PrEP in Thailand and three months afterwards. Out of 110 participants at baseline, 67 completed the follow-up. The prevalence of sexually transmitted infection (STI) testing was 47.8% during the follow-up period. Eleven participants received an STI diagnosis, and seven of them were incident infections in the past three months. Participants who perceived a higher chance for STI infection (adjusted odds ratios (AOR): 1.90, 95% CI: 1.00, 3.75) and reported higher intention to take up STI testing at baseline (AOR: 1.62, 95% CI: 1.05, 2.50) were more likely to receive STI testing during the follow-up period. Baseline perceptions that service providers would think they were having risky behaviors because of PrEP use was negatively associated with the dependent variable (AOR: 0.51, 95% CI: 0.31, 0.86). Service planning and health promotion related to STI testing is needed for MSM "PrEP tourists".

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., Competing Interests: Conflict of Interest and Sources of Funding: The authors do not have any conflict of interest.

HIV-related factors and suicide-risk status were assessed among YMSM aged 18-24 years recruited through various MSM-related online social apps in Bangkok ( N  = 1394). The online survey assessed demographic characteristics, sexual behaviours and suicide-risk status. Measure of suicide risk was taken from the Suicidal Behaviors Questionnaire-Revised (cut-off score of seven or higher). Among participants, 249 (17.9%) reported suicide-risk. In multivariable logistic regression, correlates of suicide-risk status included having sometimes or often ever participated in group sex (AOR=1.58, 95% CI: 1.17-2.14), having received money or opportunities for sex (AOR=1.54, 95% CI: 1.09-2.17), often seeking partners online (AOR=1.59, 95% CI: 1.05-2.39), inconsistent condom use (AOR=1.67, 95% CI: 1.26-2.21), and self-assessed as having "medium" or "high" HIV risk (AOR=2.53, 95% CI: 1.61-3.98 and AOR=3.35, 95% CI: 1.92-5.82, respectively). Findings suggest that HIV risk behaviours shown by YMSM are significantly associated with higher risk of suicide.
