SmartCHANGE is an innovative project funded by Horizon Europe, focusing on promoting healthy lifestyles among children and teens. It aims to tackle chronic diseases using AI tools and is currently conducting feasibility studies in countries like Finland, the Netherlands, Portugal, Slovenia, and Taiwan.
The project involves about 25-35 healthcare professionals and 500 families. Participants wear activity trackers and use a dedicated app to track health data. This setup allows healthcare providers to see a comprehensive picture of a child’s health, combining clinical information with lifestyle factors. Gregor Jurak, head of the SLOfit research team at the University of Ljubljana, explains that traditional health metrics like body mass index (BMI) can be misleading. “BMI may not reflect true fitness, especially for those genetically predisposed to higher weight but who are otherwise healthy,” he states.
By focusing on more detailed data, SmartCHANGE can better identify at-risk children who might miss detection through BMI alone. The app also enables healthcare professionals to suggest lifestyle changes and monitor progress. Privacy is ensured, as only authorized caregivers can access a child’s data.
Tuija Tammelin, a principal researcher at Jamk University of Applied Sciences, emphasizes the novelty of this approach. “While there are models for adults, this is the first tailored for children,” she points out. The project aims to engage families not just by warning them about future health risks but by inspiring healthy choices today.
A fun twist comes with the Happy Plant app, which gamifies the experience. Children and families can care for a virtual plant that thrives as they adopt healthier habits. This game-like element encourages regular participation and learning, making health feel engaging rather than daunting.
In Slovenia, early trials have focused on refining features like the plant-watering mechanic. Coordinated efforts include collaboration with school healthcare providers, such as pediatricians and dietitians. Meanwhile, in Finland, studies are school-based and involve training school nurses to connect with the 11 to 14 age group.
The feasibility studies will continue until 2025-2026, gathering data to see how effective these solutions are in altering behaviors and assessing health risks. The hope is that by integrating technology and community involvement, SmartCHANGE can help shape a healthier future for young generations.
