Can an app boost healthy habits in at-risk teens? new study aims to find out.

This study tests an online platform designed to help teenagers from low-income backgrounds eat healthier, be more active, and sit less. About 1000 students aged 11-16 from six schools in Central Catalonia will take part. Half will use the platform right away, while the other half will start later. Researchers will measure changes in physical activity, diet, and well-being to see if the program works.
