Who could benefit from this research
✓Could help
Cambodian adults living with HIV who currently smoke cigarettes, are receiving HIV care (ART), and have access to a smartphone are ideal candidates.
✕Less likely to help
People who do not smoke, are not living with HIV, lack access to a smartphone, or do not want to use mobile-based support are unlikely to benefit from this program.
What this research studies
This project offers people living with HIV in Cambodia a combined quitting program that includes medicine, counseling, and an automated interactive smartphone messaging system. Participants will be enrolled through local HIV clinics and randomly assigned to the intervention or usual care so researchers can compare outcomes. The messaging app is tailored to each person's smoking patterns and readiness to quit and provides real-time tips and motivation without needing frequent clinic visits. The team has already built the mobile platform and completed a small pilot with 50 participants, and this larger trial will follow people over time to track smoking and health outcomes.
Why it matters
Potential benefit: If successful, the program could help people with HIV in Cambodia stop smoking, improve their overall health, and extend life expectancy.
How similar studies have gone: Combined medication-plus-behavior interventions and mHealth programs have helped smokers in other countries, and the team completed a small pilot with Cambodian PLWH showing feasibility.
