Summary

This study tested two mobile apps for parents of children aged 2 to 5. One app focused on nutrition, physical activity, and sleep; the other on reading. Researchers wanted to see if the apps could help parents encourage healthier habits and lower obesity risk. Over 200 parents in the U.S. took part, using the apps to set goals and track their child's behaviors.

What this could mean

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

Active substance
Children Eating Well (CHEW) mobile app
What this could lead to
If effective, these apps could offer a simple, scalable way for parents to help their young children build healthier eating, activity, and sleep habits.
What could go wrong
This is a completed study, but results may not apply to all families. The apps rely on self-reported behaviors, and long-term impact on obesity is not yet proven.
