Intervention for Preventing Myopia and Multimorbidity in Children

This study aims to develop and evaluate a scalable, hybrid intervention model for the co-prevention of myopia, obesity, and mental health issues among children. By integrating cognitive behavioral therapy principles, the model targets key modifiable lifestyle factors-including dietary nutrition, physical activity, screen time, sleep hygiene, light exposure, and psychological adaptation-through coordinated family-school engagement and online-to-offline delivery. Using a cluster randomized controlled trial design in grades 3-4 primary school students, the research will assess the effectiveness of this multi-component strategy in reducing the incidence and burden of these co-occurring conditions.
