About the project SmartCHANGE is a 4-year long H.E. RIA project (May 2023-May 2027) Research topic is “Trustworthy AI tools to predict the risk of chronic NCDs and/or their progression”, together with a cluster of other projects SmartCHANGE is developing a “health ecosystem” through the interaction between two applications (one for families of children/youth, one for HCPs) Currently, the project is deploying a multi-pilot site testing of the system, pairing it alongside a variety of different health infrastructures in different national and social contexts. These are the 5 Feasibility Studies. 4Webinar: Putting Health Tools into practice –11/11/2025

Personal Data Protection Treatment Child's personal data that we collect during our study: Sociodemographic data: name, surname, date of birth, gender, parents' names and emails (collected personally by the school's teacher) Body height and mass (obtained with a questionnaire in HappyPlant mobile app. and with measurements taken at meetings with the healthcare team –data recorded in SmartChange web app.) Physical activity, sleeping habits, sitting habits (automatically obtained by a wearable Garmin device) Eating habits, mindfulness (obtained with questionnaires in HappyPlant app. on multiple occasions) Physical fitness (imported data from external SLOfit app.) Other sociodemographic data: parents’ education, family's socioeconomic status (obtained with a questionnaire in HappyPlant app.) Pseudonymization: replacement of personal identifiers (e.g., child’s name and surname) with a fictitious number Data storage: a server located in Slovenia
Access to collected personal data Teachers at the schools (access to data from Garmin device) Healthcare team (all data, including those calculated by AI) Authorized researcher at Faculty of Sport University of Ljubljana (all data, including those calculated by AI)
Why did we choose 11 & 14 year olds to participate in Finland? Move! a national monitoring and feedback system for all Finnish 5th and 8th grade pupils’ to measure their fitness/ physical functional capacity 20 m shuttle run, push-ups, curl-ups, 5-leap, throwing-catching, flexibility –during Physical Education lessons Main purpose is to encourage pupils to take responsibility for their own physical fitness, and to promote an active lifestyle. Move! results will be taken in expanded health checks conducted by school nurses (guardians involved) Potential use of SmartCHANGE applications in this context in future…
Recruitment process Recruitment process involved multiple phases, to first recruit the school nurses before we could start recruitment of children and adolescents at the schools Children and adolescents were recruited a) from events held in classroom and b) directly by school nurses Collaboration with local welfare district to support school nurses’ opportunity/willingness to join the study and improve children & adolescents' adherence to study visits during the school day. Children and adolescents received the HappyPlant application well during the recruitments, 11-year-olds were keener to participate than 14-year-olds.
Next steps: Starting the feasibility study Starting events at each participating schools Deliver the Garmins for the participants and ensure everyone has Garmin and HappyPlant running correctly Provide instructions and information for participants and their parents Children and adolescents begin to use the Garmin and the HappyPlant application and attend the initial meeting with the school nurse
Opportunities and local topics related to feasibility study Opportunity to assist school nurse in their work evaluating children health Incorporating the device measured lifestyle data into the process Finnish legislation was changed recently to restrict mobile phone use in the schools for children and adolescents Some schools also restrict the use of Smartwatches - Permission from schools to use activity trackers during school days was granted for the feasibility study New guidelines are in process from Finnish institute for Health and Welfare which addresses the 0-13 years old children digital device use Recommends that younger than 11-year-olds should not have their own digital device

Purpose of the Feasibility Study Main goal: test the feasibility, usability, and acceptability of SmartCHANGE tools in real-world settings. Why Portugal: family-based healthcare context with paediatricians, early lifestyle intervention, and strong clinical infrastructure. Study design: non-randomised trial with experimental and control groups.
Study Context in Portugal Target group: families with at least one child aged 6–10 years. Participants: ~100 families (50 experimental, 50 control). Setting: CUF Hospital. Recruitment: via paediatric consultations and family doctors.
Recruitment and Procedures Families invited during regular check-ups. Information brochures and consent forms will be distributed during a general meeting at the Faculty. Follow-up via phone/email if no reply within 15 days. Children wear Garmin Vivosmart 5 for physical activity monitoring.
The SmartCHANGE Tools Web App (for professionals): Shows risk profiles and key behavioural factors. AI-driven risk prediction (low/medium/high). Enables professionals to define and adjust goals. Mobile App (HappyPlant): Used by parents/children. Gamified plant growth linked to healthy goals. Focus on fun, achievable, family-oriented activities.
Role of Healthcare Professionals Professionals interpret AI-generated risks. Define intervention areas (e.g., physical activity, diet). Set SMART goals with families. Monitor progress and adjust objectives through the app. ⚠️The app does not autonomously prescribe interventions. All behavioural goals must be validated by a healthcare professional.
Outcomes Feasibility: recruitment, adherence, technical functioning. Usability: satisfaction and engagement (families + professionals). Explainability: understanding and trust in AI predictions. Clinical: changes in behaviour, BMI, activity levels, etc.
Expected Impact Promote early health literacy and prevention. Strengthen collaboration between families and healthcare providers. Support clinical decision-making with explainable AI. Provide model for scalability to other EU countries.
