Texting program aims to help smokers with HIV kick the habit
NCT ID NCT05863923
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study tests whether personalized text messages can motivate people living with HIV in Vietnam to quit smoking. Participants receive motivational texts over six months and are encouraged to use a free government quitline that provides nicotine patches. The goal is to see if this approach increases smoking cessation rates compared to receiving only basic facts about smoking risks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- motivational text messages
- What this could lead to
- If it works, this could point toward a low-cost, scalable way to help people with HIV quit smoking, reducing their risk of tobacco-related diseases.
- What could go wrong
- This is a behavioral intervention, not a drug, so results depend on participants' engagement. The study is also specific to Vietnam, so findings may not apply elsewhere.
