title: [Rates of frailty among older people ascribed to Chilean primary care clinics].
abstract: BACKGROUND
  Frailty is not universal among older people but increases the risk of dependence.
  
  
  OBJECTIVE
  To assess frailty among older people and its relationship with biological, psychological and social factors.
  
  
  METHODS
  Seven hundred fifty four older people aged 73 ± 6 years (61% females), attending a public primary care were assessed. Frailty was defined according to Fried criteria that considers inexplicable weight loss, tiredness, muscle weakness and lack of physical activity.
  
  
  RESULTS
  Absence of frailty, pre-frailty and frailty was found in 26, 69 and 5% of participants, respectively. Significant differences between frailty groups were observed for age, gender, years of studies, minimental and self-efficacy scores. Among participants defined as being in a pre-frail condition, 59% were non-disabled without risk and 41% non-disabled in risk, according to the functional assessment for older people used in Chilean primary care clinics.
  
  
  CONCLUSIONS
  Frailty among older people is associated with increasing age, education, cognitive status and self-efficacy.
