Summary

This study tests a mobile app called 'Applícate por tu salud' that sends parents tips, recipes, and videos to encourage healthy eating and physical activity for their school-aged children. About 743 children from 4 primary schools in Mexico City will take part, with some schools using the app and others serving as a control group. The goal is to see if the app can help prevent overweight and obesity by improving breakfast and lunch habits over 12 months.

What this could mean

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

Active substance
mobile health application (Applícate por tu salud) with educational content
What this could lead to
If it works, this could provide an effective, low-cost tool for parents to help prevent childhood obesity at a community level.
What could go wrong
This is a behavioral intervention, not a drug, so results depend heavily on parent engagement. The study is early-stage and may not show significant changes in BMI.
