Sexualized alcohol and drug use among men who have sex with men and the PrEP retention in Thailand.
Sexualized alcohol and drug use among men who have sex with men and the PrEP retention in Thailand.
Sexualized substance use among Thai men who have sex with men was associated with reduced PrEP retention in a clinic-based cohort study.
This study demonstrates that substance use specifically in sexual contexts creates distinct barriers to HIV prevention adherence beyond general substance use patterns. The syndemic framework linking substance use, mental health symptoms, and trauma experiences provides a useful clinical lens for understanding multiple co-occurring health risks in this population.
PrEP retention is critical for HIV prevention effectiveness, and this study identifies a specific behavioral pattern that clinicians should screen for when prescribing PrEP to MSM patients. Understanding that sexualized substance use creates unique adherence challenges can inform targeted retention strategies and counseling approaches.
| Study Type | Mixed-methods cohort study |
| Population | 100 Thai men who have sex with men recruited from community clinic |
| Intervention | Assessment of sexualized alcohol use (SAU) and sexualized drug use (SDU) |
| Comparator | MSM without sexualized substance use |
| Primary Outcome | PrEP retention rates |
| Key Finding | Sexualized substance use associated with reduced PrEP retention |
| Journal | Drug and Alcohol Dependence Reports |
| Year | 2024 |
Clinicians prescribing PrEP to MSM should specifically assess for substance use in sexual contexts, not just general substance use patterns. Patients reporting sexualized alcohol or drug use may benefit from enhanced retention support and monitoring.
The study does not establish causation between sexualized substance use and PrEP discontinuation, nor does it demonstrate that addressing substance use improves retention. The mechanisms linking sexualized substance use to poor retention remain unclear from this analysis.
The study is limited to one clinic setting in Thailand, potentially limiting generalizability to other populations or healthcare systems. Self-reported substance use and sexual behaviors may be subject to recall bias or social desirability bias, and the cross-sectional design limits causal inference.
Sexualized substance use represents a distinct clinical pattern that warrants specific attention in PrEP care. While this study identifies an important association, clinicians should focus on enhanced monitoring and support for these patients while awaiting evidence on effective intervention strategies.

FAQ
What is sexualized substance use and how does it affect PrEP adherence?
Sexualized substance use involves using alcohol or drugs in sexual contexts, which can impair judgment and decision-making around safe sex practices. This study found that sexualized substance use among Thai MSM was associated with reduced PrEP retention, potentially compromising HIV prevention effectiveness.
Should clinicians screen for substance use when prescribing PrEP to MSM patients?
Yes, routine screening for both alcohol and drug use in sexual contexts should be part of comprehensive PrEP care. Early identification allows for targeted interventions and closer monitoring of PrEP adherence in high-risk patients.
A psychosocial syndemic refers to co-occurring conditions like substance use, depression, anxiety, and trauma that interact synergistically to worsen health outcomes. Understanding these interconnected factors helps clinicians provide more comprehensive care and identify patients at higher risk for poor PrEP retention.
How can mobile health interventions help MSM patients on PrEP who use substances?
Mobile health interventions can provide accessible, discreet support for medication adherence, substance use monitoring, and mental health resources. The study explored acceptability of these digital tools as adjuncts to traditional clinical care for improving PrEP retention.
What additional support should be offered to MSM patients who report sexualized substance use?
Patients should receive integrated care addressing both substance use and HIV prevention, including counseling on harm reduction strategies and more frequent follow-up visits. Referral to substance abuse treatment and mental health services may be necessary for comprehensive care.
