Towards a Vision of Sustainable Health: Definitions, Related Concepts and Key Dimensions

Contemporary societies are facing converging crises, including environmental degradation, worsening social inequalities, aging populations, and increasingly costly healthcare systems, prompting sustainable health to be proposed as an integrative conceptual perspective for rethinking health, its determinants, and collective action. This narrative review aims to trace the historical evolution of the concept, clarify the vision it offers for public health, and identify its implications for research, policy, and intervention. A literature search (May 2025) was conducted in PubMed, Google Scholar, and Google, with no restrictions on language, time period, or document type. Of 40 relevant documents, 21 were selected for in-depth analysis by two independent reviewers, with duplicate data extraction. The results show that sustainable health broadens the World Health Organisation (WHO) definition of health by incorporating sustainability, intergenerational justice, ecological limits, and social equity. Close to, but distinct from Planetary Health, One Health, and EcoHealth, sustainable health is based on ecological, social and ethical, economic, behavioral, intergenerational, and systemic/intersectoral dimensions. Sustainable health thus emerges as a systemic and transdisciplinary conceptual approach for transforming health systems, living environments, and public policy, requiring further conceptual clarification, robust interdisciplinary research programs, and intersectoral initiatives involving communities.
