To explore the associations of (1) the frailty phenotype or frailty index transition with cause-specific mortality, and (2) different combinations of transition in frailty phenotype and frailty index with all-cause mortality.
Frailty renders older individuals more prone to adverse health outcomes. Little has been reported about the transitions between the different frailty states. We attempted to examine the rate of these transitions and their associated factors.
Aging researchers have been studying frailty for decades. Experts agree that frailty is a medical syndrome marked by reduced physiologic function, which increases the risk of vulnerability and short-term mortality, particularly in the face of a stressor. Frailty has been shown to predict poor outcomes incl...
