AbstractThis research was carried out to validate a framework of game-based childhood
obesity prevention. A mobile game titled Fight Obesity 2.0 was produced through a
five-step gamification approach as an instance of the prevention framework. The
game incorporated constructive alignment of intended prevention outcomes and
structural game elements. The lean production strategy was deployed to produce a
viable serious game with its paratextual materials. The design of the game was
validated by 38 game designers through a playtesting session, while the content
knowledge was validated by two pediatricians, one from China and another in
Malaysia. The game also passed the age rating test under the International Age Rating

investigated through a non-equivalent control group pre-test / post-test quasiexperiment.
Edumetric tests were conducted with 60 children at the kindergarten in
the National Child Development .....
