What this trial studies

This study evaluates the effectiveness of a digital program called Healthy Together ('Juntos') aimed at preventing obesity among Hispanic adolescents aged 12-15. The program focuses on improving physical activity levels, diet quality, and body composition through family involvement and digital engagement. Participants will use web and mobile platforms to access resources and support for healthier lifestyle choices. The study targets adolescents who do not meet physical activity and dietary recommendations and live with a participating parent or guardian.
