La fragilidad como predictora de mortalidad en una cohorte de edad avanzada

Abstract

Objective: To determine the association between frailty in older persons and mortality in the city of Lleida (Spain) between 2009 and 2012. Methods: We conducted a prospective longitudinal study based on persons living in the city of Lleida aged 75 years and older, covered by the public health system and living in single-family households. The cross-sectional study was performed between 2009 and 2010 and longitudinal study was carried out 3 years later (median 25 months). Results: Survival was lower in frail individuals than in pre-frail and non-frail individuals (log rank. =. 10.56; p. =. 0.005). In addition to frailty (HR. =. 4.95; 95%. CI: 1.71-14.31). Age was also a significant predictor (HR. =. 2.87; 95%CI: 1.02-8.26). Conclusion: A higher level of frailty was associated with an increased risk of death at 2 years in a prospective cohort of elderly persons older than 75 years living in their own homes in the city of Lleida.
