Design, implementation and evaluation of a serious game for obesity prevention among preschool children

This paper presents the design, implementation and evaluation of a kindergarten based prevention on childhood obesity among preschool children. The prevention applies motivational game-based learning and behaviour change theories during design. Preschool children are the main target group for this study because preschool childhood obesity has been found correlated to obesity in later years of childhood, thus preventing and treating preschool obesity are particularly important. There have been few preventionand interventions that have targeted game based strategies in the kindergarten to promote health outcomes in preschool children and especially in Asian countries. To our knowledge,Fight Obesity 2.0is the first mobile application in Southeast Asia. In this study, it shows a positive way for the content experts and subject experts to collaborate with each other to design and develop digital mobile games for preschool children, we discuss in detail the challenges faced while designing and implementing this trial. Finally, we present the evaluation results from the three-scope validation strategy
