Healthy ageing is essential to strengthening health systems, supporting economic growth, and improving quality of life for older adults. It goes beyond longevity—focusing on maintaining physical, mental, and social well-being throughout the later stages of life.

This Resource Kit provides a comprehensive overview of the key concepts, determinants, and strategies that shape healthy ageing. It explores the foundational elements of functional ability and intrinsic capacity, the influence of biological, behavioral, social, environmental, economic, and policy factors on ageing outcomes, the challenges faced by ageing populations, and how to address inequalities in healthcare access and support services, and the importance of collaborative, cross-sector approaches to building sustainable, age-inclusive health systems around the world.
