Abstract
In both demographic and clinical studies, frailty is understood as a multidimensional state of increased vulnerability compared with the status of others of the same age. Of the many theoretical definitions of frailty, two are commonly employed: the physical frailty/phenotypic approach and the deficit accumulation approach. The purpose of this chapter is to discuss how frailty is conceptualized and operationalized based on these two approaches.
期刊介绍：
At a time when interest in the process of aging is driving more and more research, ''Interdisciplinary Topics in Gerontology and Geriatrics'' offers investigators a way to stay at the forefront of developments. This series represents a comprehensive and integrated approach to the problems of aging and presents pertinent data from studies in animal and human gerontology. In order to provide a forum for a unified concept of gerontology, both the biological foundations and the clinical and sociological consequences of aging in humans are presented. Individual volumes are characterized by an analytic overall view of the aging process, novel ideas, and original approaches to healthy aging as well as age-related functional decline.
