Summary

This study tests whether mobile health support (text messages and chat-based coaching) and financial incentives (up to HK$500) can help 1200 older, low-income smokers in Hong Kong quit. Participants are aged 60+ and smoke daily. The main goal is to see if these approaches lead to verified smoking abstinence after 6 months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
mobile health support and financial incentives
What this could lead to
If successful, this could provide an effective, scalable way to help older, disadvantaged smokers quit for good, reducing smoking-related diseases.
What could go wrong
This is a behavioral intervention trial, not a drug. Results may not apply to other populations, and long-term abstinence rates could be modest.
