Behavioural Science Interventions to Improve Health Equity

The goal of the HealthyW8 study (an intervention study) is: To assess the usefulness and effects of a digital-based healthy lifestyle recommender system (HRLS) on the prevention of obesity in the following propulations: schoolchildren (5-10 y) and their parents, young adults (18-25 y) and elders (\>65 y). The main questions it aims to answer are: Outcome 1: To select and validate a tool-assisted 3-mo intervention (mostly digital) by iteratively testing the HLRS on reducing risk of overweight/obesity among the described age groups. Outcome 2: To assess the effect of 1-y interventions (mostly digital) with the HLRS described and further iteratively improved previously (outcome 1) on reducing risk of overweight/obesity at described ages. Researchers will compare the intervention group before the intervention (baseline) and after it (3-mo intervention trial), or control group (standard care) vs. Intervention group (1-y intervention) to see changes on changes in overweight/obesity, and related parameters (body composition and biomarkers). Participants will follow the HLRS recommendations (meal plans, physical activity and sleep pattern measures and recommendations, assessment of behavioural/psychological aspects, and motivational features through digital devices), which will be assessed by means of measurement of body weight, body composition, and biomarkers.
