Moving Toward a Global Age-Friendly Ecosystem.

The designation of "age friendly" has clearly engaged the attention of scholars and leading experts in the field of aging. A search of PubMed references citing the term produced 15 results in the 5-year period from 2006 to 2011; that number increased to 572 in the period from 2015 to 2019. The work, notably led by the World Health Organization with the initiation of age-friendly cities and age-friendly communities, has now sparked a movement for the creation of age-friendly health systems and age-friendly public health systems.
