App and coach team up to help women kick the habit
NCT ID NCT04865276
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a program that combines community health worker visits with a smartphone app to help low-income women stop smoking. About 344 women in Brazil will either get the app plus health worker support or just a referral to a standard quit-smoking clinic. The goal is to see if more women stay smoke-free for at least 7 days 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
- Community health worker visits plus a smartphone app to support quitting smoking
- What this could lead to
- If it works, this could provide an effective, low-cost way to help women quit smoking in underserved communities.
- What could go wrong
- This is a mid-stage trial with 431 participants, so results may not apply to all smokers. The program relies on smartphone access and community health workers, which may limit use in some areas.
