Cancer and frailty in older adults: a nested case-control study of the Mexican Health and Aging Study.

ABSTRACT:

Understanding how the convergence between chronic and complex diseases-such as cancer-and emerging conditions of older adults-such as frailty-takes place would help in halting the path that leads to disability in this age group. The objective of this manuscript is to describe the association between a past medical history of cancer and frailty in Mexican older adults.

Frailty was categorized by developing a 55-item frailty index that was also used to define cases in two ways: incident frailty (incident >0.25 frailty index score) and worsening frailty (negative residuals from a regression between 2001 and 2012 frailty index scores). Exposition was defined as self-report of can
