RESUMEN
Introduction: Based on the ICAPS approach, funded by the Regional Health Agency of Île-de-France and the Mutualité Française Île-de-France, a programme to promote the health benefits of physical activity has been conducted since 2012 in Clichy-sous-Bois, a town with major health inequalities. The objective was to implement intersectoral local projects designed to encourage physical activity among young people.Method: An initial assessment identified the lack of collaboration between sport, social, education and health stakeholders. Seven priority work areas were highlighted: creation of municipal synergy, training of local actors in the implementation of "Physical Activity and Health" joint projects, creation of local courses to identify / inform / advise and guide residents towards adapted physical activities, implementation of programmes combining physical activity and a balanced diet in primary and secondary schools, community centres and municipal school sports.Results: Regular meetings between local partners/actors facilitate the implementation of many projects that meet the expectations/needs of residents and professionals. For example, in a community centre, women and children learned to ride a bike, mediators passed a diploma to supervise groups, outings were organized and the planning authority/department decided to study the feasibility of building cycle paths.Conclusion: The sharing of ideas and local resources constitutes a lever to encourage physical activity and reduces social inequalities in health. A partnership culture between sport, social, education and health structures must be developed in order to integrate physical activity as one of the Local Health Contract's priorities.
