Children's Cooperation Denmark: a 3-year System Dynamics Trial

First, local health profiles of children will be collected and used to engage key leaders and stakeholders from intervention communities and municipal administrations in participatory processes. These will be used to develop a systems map of drivers of PA behaviour in schoolchildren aged 6-12 years in the local communities. Second, based on the systems map, stakeholders from the civic and private sectors will be involved in developing and implementing actions to promote healthy PA behaviour through system changes.
