A Mobile App to Improve 24-Hour Movement Guideline Adherence in Preschoolers

Summary

The goal of this clinical trial is to evaluate whether a home-based mHealth intervention can improve adherence to the 24-Hour Movement Guidelines in preschool-aged children (3-4 years old) who currently meet 0 or 1 of the guidelines for physical activity, sedentary behavior, and sleep. The main questions it aims to answer are:

* Can the intervention increase the proportion of children meeting all three 24-Hour Movement Guidelines (physical activity, screen-time, and sleep)?
* Is the intervention feasible for parents to implement, as measured by a parent feedback survey?

Researchers will compare an intervention group to a waitlist control group to assess whether the intervention leads to increased guideline adherence.

Parents and Participants:

* Children will wear an accelerometer to track physical activity and sleep patterns.
* Parents will use a mobile app that delivers weekly lessons and behavior-related goals to encourage healthy movement behaviors in their children.
* Parents will complete questionnaires on their child's movement behaviors and development at baseline, 6 weeks, and 12 weeks.
* Additionally, children will undergo motor skills assessments, and parents will provide feedback on cognitive development and behavioral changes.

Shining Star mHealth App

The Shining Star mHealth App Intervention is a 12-week mobile health program designed to improve adherence to the 24-Hour Movement Guidelines (physical activity, screen time, and sleep) among preschool-aged children (3-4 years old). The intervention delivers weekly behavior-related goals and educational lessons to parents through a mobile app, including concise messages (\<500 characters) and links to additional resources. The app also includes gamification features, behavior trackers, and a \"Kids Corner\" for child-friendly content. Parents receive reminders and can engage with other participants through an optional chat forum.
