Childhood obesity is becoming one of the 21st century’s most important public health problems. Nowadays, the main treatment of childhood obesity is behavior intervention that aims at improve children’s lifestyle to arrest the disease. Information and communication technologies (ICTs) have not been widely employed in this intervention, and most of existing ICTs systems are not having a long-term effect. The purpose of this work is to define a system to support family-based intervention through a state of the art analysis of family-based interventions and related technological solutions first, and then using the Analytic Hierarchy Process (AHP) to derive a childhood obesity family-based behavior intervention model, and finally to provide a prototype of a system called “OB CITY”. The system makes use of applied behavior analysis, affective computing technologies, as well as serious game and gamification techniques, to offer long term services in all care dimensions of the family-based behavioral intervention aiming to provide positive effects to the treatment of childhood obesity.
