Study name	The SI! Program for Secondary Schools
Methods	Study design: cluster‐randomised controlled intervention
Participants	School type: secondary schools. Adolescents aged 12–16 years in grades 1–4 Region: Barcelona and Madrid
Interventions	Number of experimental conditions: 3 (1 long intervention, 1 short intervention, 1 control) Policies, practices or programmes targeted by the intervention The intervention consists of teacher‐led computer‐based simulations and games (virtual trip) targeting the different age groups (grades 1–2 or 1–4). The minimum intervention load is 18 hours per year in the short‐term intervention group and 12 hours per year in the long‐term intervention group. The health challenge topics (healthy eating, physical activity and substance abuse avoidance) are integrated into the regular curricular subjects (science, PE, etc.) and are designed to stimulate a range of motivational pathways related to the diverse content through a shared methodology. Implementation strategies EPOC: audit and feedback ‐ Annual report EPOC: educational materials ‐ Newsletters EPOC: educational meetings ‐ Meetings between a co‐ordinator from the SHE Foundation and the designated health co‐ordinator, together with the other participating teachers at the school. ‐ A health day will be held in each academic year and will include participation of teachers, adolescents and families. ‐ Receive training in the promotion of cardiovascular health in the school setting. ‐ Health fair.
Outcomes	Outcome relating to the implementation of childcare service policies, practices or programmes School principal will complete a survey containing questions related to recommendations made by the SI! Program. These questions will deal with the type of foods permitted on the school premises (including products offered in the cafeteria or vending machines), measures to promote active commuting to and from school (walking or cycling) and physical activity during recess, and conflict resolution.
