Juntos Santiago: Gamification Strategy to Reduce Childhood Obesity in Schools in Santiago de Chile

"The intervention is a gamification strategy, including game elements such as points, levels and rewards. Points are scored by completion of healthy challenges, i.e. a healthy snacks challenge, a steps challenge and activity challenge. Intervention takes place for 8 months from Mar to Nov. There will be three levels. Level 1 at baseline, level 2 expected at month 4 by 100% of participants and level 3 expected in month 8 by 70% of participants. A new cycle will start in 2019.~Rewards include an initial reward (Starting Kit), a structural reward and an activity reward. The Starting Kit is a box with souvenirs, information for students and teachers. A structural reward, at level 2, will be achieved collectively by all participating classes in one school. It consists of school infrastructure improvements to promote a healthy nutrition and PA (eg. climbing wall, shared bicycles, sports equipment). An activity reward (AR), when reaching level 3, consists of a fun and healthy activity."
