Testing a Game-Based Health Program to Help Children Develop Healthy Habits

This study is testing whether turning health education into a game makes it more effective for helping primary school children develop healthier habits. The program lasts 6 months and involves fun, gamified activities that encourage children to improve their diet, physical activity, and screen time — with support from both teachers and families. Different groups will receive different combinations of weekly lessons and reward systems to see what works best.

Childhood obesity is a major health problem affecting about 4 in 10 children in Spain, and it often starts with unhealthy eating, too little physical activity, and too much screen time. This trial exists because researchers want to find out if making health education into a game — with achievements and rewards — helps children stay motivated to build better habits and prevent obesity before it becomes a lifelong problem.
