The Increasingly Global Nature of Research in Aging

As the world's population ages and services for older persons occupy an increasing share of governmental resources, it has become increasingly urgent to understand and address the needs of this growing demographic.1 Of particular interest are older persons who require post-acute and long-term care, because they epitomize the challenges of caring for an aging society—functional loss, social isolation, geriatric syndromes, multimorbidity, most intense use of health services, highest risk of morbidity and mortality, and maximum likelihood of both benefit and harm from health care.
