Who could benefit from this research
✓Could help
Adults (21 years and older) living with HIV in Cambodia who currently smoke cigarettes and are receiving antiretroviral therapy are the ideal candidates.
✕Less likely to help
People who do not smoke, are younger than 21, are not located in Cambodia, lack smartphone access, or decline medications or messaging support are unlikely to benefit from participation.
What this research studies
You would receive interactive, tailored messages on your smartphone designed to support quitting, along with pharmacologic treatment when appropriate. The program combines behavioral messaging and medication and is delivered automatically through an mHealth platform that the team already piloted in Cambodia. People will be randomly assigned to the messaging-plus-medication approach or a comparison group so researchers can see which helps more people quit. Study staff will follow participants over time while they continue their HIV care to track smoking and health outcomes.
Why it matters
Potential benefit: If successful, this approach could help more people with HIV in Cambodia quit smoking and improve their long-term health and survival.
How similar studies have gone: Similar smartphone and text-message programs have shown promise for helping smokers quit in higher-income countries and a small Cambodian pilot demonstrated feasibility, but larger trials are needed to confirm effectiveness.
