This study is a cluster randomized trial carried out in schools of secondary cities of four low- and middle income countries. Baseline surveys in 30 randomly selected schools will assess the health behaviours of 13-17 year old students as well as school policies and practices. The intervention arm (15 schools) will use the baseline information to develop a package of actions in collaboration with students, teachers, and local authorities that will subsequently be implemented an monitored over two years. Follow-up surveys to evaluate the effectiveness of the implemented actions will be conducted after two years in all 30 previously selected schools.
