title: [Frailty as a predictor of mortality in a cohort of people aged 75 years and older].
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).
  
  
  CONCLUSIONS
  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.
