School-based interventions have shown mixed results. Most studies have lacked enough statistical power and have been carried out in North America and Europe.
The Juntos Santiago is a cluster-randomized trial based on a gamification strategy conducted in Santiago de Chile. The trial uses elements of a game such as points, levels and rewards along with a strong community participation component.
Children voted their enrollment and collectively chose the rewards (two per year, one activity and another structural) they are playing for. The intervention consists of a healthy snacks challenge, a steps challenge and an activity challenge. The primary outcome is change in z-BMI and waist circumference.

Gamification strategy. In 2018, the intervention group are 15 schools from Municipality of Santiago. In 2019, the intervention will cover all eligible schools in the Municipality of Santiago.
Behavioral: Gamification strategy
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.
No Intervention: Control
In 2018, the control group will be 5 randomly selected schools from Municipality of Santiago and 4 schools from Municipality of Estación Central. In 2019, the control group will be 4000 participants chosen from neighboring municipalities
- Change in zBMI [ Time Frame: Measured at baseline and 8 months ]Change in zscore of body mass index at 8 months
- Change in waist circumference [ Time Frame: Measured at baseline and 8 months ]Change in waist circumference measured using standard protocols at 8 months
- Change in BMI [ Time Frame: Measured at baseline and 8 months ]Change in body mass index (weight/height squared) at 8 months. Weight and height will be combined to report BMI in kg/m^2
- Change in SBP [ Time Frame: Measured at baseline and 8 months ]Change in systolic blood pressure at 8 months
- Change in DBP [ Time Frame: Measured at baseline and 8 months ]Change in diastolic blood pressure at 8 months
