What this trial studies

This clinical trial evaluates a home-based mobile health intervention designed to improve adherence to the 24-Hour Movement Guidelines among preschool-aged children (3-4 years old) who currently meet few or none of these guidelines. The study involves a randomized controlled design with an intervention group using a mobile app that provides weekly lessons and behavior goals, while a waitlist control group will receive the app after the intervention period. Key measurements will assess changes in physical activity, sleep patterns, and other developmental outcomes over a 12-week period.

Who should consider this trial

Good fit: Ideal candidates are preschool-aged children (3-4 years old) who currently meet 0 or 1 of the 24-Hour Movement Guidelines for physical activity, sleep, and screen-time.

Not a fit: Children who have mobility limitations or who already meet two or more of the movement guidelines may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly enhance the physical activity, sleep quality, and overall health of preschool-aged children.

How similar studies have performed: While similar mobile health interventions have shown promise in promoting physical activity and healthy behaviors, this specific approach targeting preschoolers is relatively novel.
