A service-based system for malnutrition prevention and self-management

Malnutrition is considered one of the root causes of the occurrence of other diseases. It is particularly common in the aging population, where it requires more efficient handling and management to enable longer home independent living. However, to achieve a number of related challenges need to be overcome, especially those related to management of health and disease let alone other social and logistical barriers. This paper presents the design of a distributed system that enables homecare management in the context of selffeeding and malnutrition prevention through balanced nutritional intake. The design employs a service-based system that incorporates a number of services including monitoring of activities, nutritional reasoning for assessing feeding habits, diet recommending for food planning, and marketplace invocation for automating food shopping to meet dietary requirements. The solution is deployed in a small pilot in 12 elder adult houses that, in early results, demonstrates its holistic user-centred scalable approach for malnutrition selfmanagement.
