Summary

This study tests a web application called VA|PREVENTION that uses a virtual coach to help adults at high risk for type 2 diabetes make healthier choices. 180 participants will either use the app or receive a standard guidebook. Researchers will measure changes in waist circumference and diabetes risk over 10 months.

What this could mean

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

Active substance
VA|PREVENTION web application (digital intervention with virtual coach)
What this could lead to
If successful, this could provide an effective, scalable digital tool to help prevent type 2 diabetes in at-risk adults.
What could go wrong
This is a relatively small trial (180 people) testing a behavioral intervention, so results may not be generalizable. The app may not be more effective than standard educational materials.
