Samenvatting

Background Encouraging healthy eating behavior and increasing physical activity can improve health, vitality, and quality of life. Individuals and health professionals have specific needs and wishes. Creative technology allows personalization of blended lifestyle programs that support behavior change by presenting persuasive elements and self-regulation. However, the development of such personalized digital tools are time consuming and expensive. New research projects with regard to physical activity and/or nutrition that apply creative technology often start from scratch, while many of the core components are generic. Therefore, we aim to develop a modular platform that serves as a foundation to build several lifestyle applications for various populations, while taking into account the specific needs of the end users. To demonstrate how we can use the platform for a blended lifestyle program regarding physical activity and nutrition, the SONUTS application was developed. SONUTS helps older adults to maintain or lose weight while preserving muscle mass and function. Description of the application Our Modular E-health platform supports three end users: clients, health professionals, and researchers. It enables the use of various behavior change techniques such as goalsetting and action planning. The SO-NUTS application, that has been built on the platform, offers clients to track their dietary intake and physical activity, goal setting, evaluation, communication with health professional and in the future with members of the community. The health professional can track progress and can adjust goals when necessary. Data from both clients and health professionals can be retrieved by researchers, clients and professionals to determine effectiveness of the intervention. Practical description of demo We will present a clickable demo version of the SO-NUTS application that was built on the modular platform. Moreover, we will show various options of the modular platform to demonstrate its use in the development of new applications for future research projects.
