ABSTRACTBackground: There is little empirical research into lay definitions of frailty.
Objectives: (1) To explore the definitions of frailty among older men, and (2) to explore if these definitions match commonly used clinical definitions of frailty.
Methods: Analysis of open-ended questions to survey data from a prospective cohort study of older airmen. The definitions of frailty were elicited, and grouped according to themes.
Results: 147 men responded (mean age: 93). There was considerable heterogeneity in older men's' definitions of frailty, and no theme of frailty was predominant. The most common theme was impairment in activities of daily living. Older men's' definition of frailty was not consistent with any commonly used medical theory of frailty.
Conclusions: Most older men think frailty is important, but their definitions are not consistent. Frailty may be a heterogeneous experience, which different people experience differently.
