NCT ID NCT06337708
First seen Jul 17, 2026 · Last updated Jul 17, 2026
Summary
This study tests a smartphone program called Smart Walk, designed specifically for African American women who are not very active. The program includes an app, virtual coaching, and text messages to encourage more physical activity. Researchers want to see if it helps women exercise more and lowers their risk for heart disease and type 2 diabetes. Participants will use the program for several months and have their activity and health measured.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a culturally tailored smartphone-delivered physical activity intervention called Smart Walk, which includes an app, virtual coaching, and text messages
- What this could lead to
- If effective, this approach could offer a scalable, culturally relevant way to increase physical activity and reduce heart disease and diabetes risk in African American women.
- What could go wrong
- This is a mid-stage trial with 210 participants, so results may not apply broadly. The intervention relies on smartphone access and motivation, which may limit its impact for some.
