The body of evidence on structural prevention is scarce and needs further development. This study contributes to international research by analysing 10-year outcomes of a multicomponent programme promoting a healthy sports setting in Switzerland. Data were collected in 2007, 2011 and 2015, enabling a longitudinal perspective on outcomes. Telephone interviews, case studies, online-surveys and analysis of key documents and data were conducted. The programme «cool and clean» is well known and accepted by key partners. Partnering between the health and the sports sector has improved visibly and cantonal ambassadors are well established.
