BackgroundDespite a well knowledge about links between urban planning and health, practices’ analyze highlights the difficulty to upgrade health into urban planning decisions. To overcome this issue, the EHESP has initiated a specific research dedicated to the development of tools for a better integration of health & wellbeing at different decision-making-level (urban planning & urban development project). The objective of this presentation is to focus on one dedicated research, Isadora project, and to share how the project was carried out to enable the production of an operational tool dedicated to urban planners to better integrate health issues into their practices.MethodsThe scientific management team mixed various skills from public health, environment and urban planning sectors which makes easier the implementation of two key-principles of research: (i) to adopt a systemic approach to health determinants, (ii) to address urban settings through an integrated approach to public health, environment and sustainable development issues. The implementation of this interdisciplinary and intersectorial project is based on a close collaboration with a national working group composed of various professionals and academics (urban planning, environment, and health). The Isadora project deliverables results from an iterative process between all the stakeholders involved in the project.Results and conclusionsFirst, we will present how we facilitated the working group throughout the deliverables development process and how we overcame the challenges of implementing intersectorality. Then, we will present the operational tool structured around of 15 key sheets with health focus to help professionals to integrate health at each step of an urban development project.
