Heavy drinking and risky sex: a text-based intervention aims to cut HIV risk
NCT ID NCT05729256
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This study looks at how heavy drinking affects sexual decision-making in men who have sex with men (MSM) and whether a brief intervention can reduce risky behavior. Participants receive either a single motivational session plus text messages or basic information about drinking and safe sex. The goal is to lower rates of condomless anal intercourse and heavy drinking, ultimately helping to prevent HIV.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a brief motivational intervention and text messages to reduce heavy drinking and sexual risk behavior
- What this could lead to
- If successful, this could point toward a simple, scalable way to reduce HIV transmission among men who have sex with men who drink heavily.
- What could go wrong
- This is a behavioral study, not a drug trial, so results may be modest and depend on participants' honesty and engagement. The intervention may not work for everyone.
