Summary

This study looks at how to best bring MINISTOP 3.0, a mobile app for parents, into Swedish primary child healthcare. The app aims to help parents of 2.5- to 3-year-olds encourage healthy eating, physical activity, and less screen time. Researchers will compare two ways of rolling out the app to see which is more acceptable, feasible, and cost-effective for nurses and clinics. The goal is to find the best approach to prevent childhood obesity on a large scale.

What this could mean

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

Active substance
MINISTOP 3.0, a mobile health app for parents that provides information, monitoring, and feedback on diet, physical activity, and screen time for young children
What this could lead to
If successful, this could show how to best integrate a digital obesity prevention tool into routine child healthcare, potentially reducing childhood obesity at a population level.
What could go wrong
This trial focuses on how well the program is adopted by nurses and clinics, not directly on child weight outcomes, so its impact on obesity remains uncertain. The app's effectiveness may also vary across different healthcare settings.
