11.D. Scientific session: Participatory approaches and co-creation in complex interventions to reduce inequity in health

Abstract The escalating challenges posed by climate change and rapid urbanization demand an integrated understanding of how our natural and built environments influence health outcomes. This workshop aims to dissect the complex associations between the environment-both natural and constructed-and physical and mental health. The urgency and breadth of these issues necessitate a multidisciplinary approach, leveraging insights from environmental science, public health, and urban planning. The primary objective of this workshop is to elucidate the multifaceted relationships between environmental conditions and health, identifying actionable strategies to mitigate adverse health outcomes and enhance well-being. Specific goals include: i) to assess the current scientific evidence linking various environmental factors with health, highlighting the role of climate change; ii) to explore innovative methodologies for studying environmental impacts on health; and iii) to foster collaboration among researchers, policymakers, and practitioners for integrated health and environmental planning. Organizing this workshop presents several unique added values. First, it serves as a platform for experts from diverse fields to share findings and refine research methodologies. Second, by synthesizing current knowledge, the workshop will inform more coherent and science-based public health and urban policy. Lastly, it could facilitate networking among stakeholders, fostering collaborations that bridge gaps between research and policy implementation. The workshop is structured to ensure thematic coherence and maximally beneficial interactions among participants. Presentations will be grouped into four thematic blocks: 1. effects of climate change on health; 2. healthy design and public mental health; 3. Planetary health challenges to human health; 4. Climate change perception and mental health. During the workshop, each speech will be built on the previous one in a sequential way. At the end of the workshop, audience members could join the discussion offering their point of view and directly interacting with the speakers. This workshop stands as a crucial endeavor to integrate diverse perspectives on how environmental conditions impact health and to catalyze significant strides in public health and urban planning. It promises to not only advance scientific understanding but also to translate this knowledge into practical, scalable solutions for health resilience in our communities. Key messages • Urban health is foundational for sustainable cities, integrating health into all policies ensures inclusive, safe, resilient communities as outlined in SDG 11. • Public health influenced by environmental and local government strategies highlights the need for multidisciplinary approaches to adapt urban planning and health policies.
