- Original description
This project aims to compare the effectiveness of Wellnuts, an evidence-based, algorithm-driven self-health assessment mobile application, in empowering asymptomatic young-to-midlife adults in Hong Kong, promoting health awareness, and improving health-seeking behaviour and linkage-to-care, compared with conventional web-based health resources. Participants will be randomly allocated to the mobile health intervention group (Wellnuts app with self-health assessment and health information) and the conventional web-based resources control group (health information from Centre for Health Protection website). Hopefully, population health will be improved with the general health promotion impact from the app.Read full original descriptionShow less
