Summary

This study follows 874 children aged 3 to 5 over one year to understand how using interactive devices like tablets and smartphones affects their thinking, social skills, and physical health. Parents will install an app to track device use, and researchers will measure development through games and questionnaires. The goal is to provide clearer guidance for families and policymakers.

What this could mean

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

What this could lead to
If successful, this could provide clear evidence to help parents and policymakers set better guidelines for young children's screen time.
What could go wrong
This is an observational study, not a treatment trial. It can show links but not prove cause and effect. Results may not apply to all children or families.
