摘要

在人口统计学和临床研究中，脆弱被理解为一种多维状态，与同龄的其他人相比，脆弱性增加。在许多关于虚弱的理论定义中，有两种是常用的:身体虚弱/表型方法和缺陷积累方法。本章的目的是讨论基于这两种方法的脆弱性是如何概念化和操作化的。

Operationalizing Frailty Using the Frailty Phenotype and Deficit Accumulation Approaches.

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.
