title: [Longitudinal study of fractures in institutionalized elderly].
abstract: OBJECTIVE
  Evaluation of fracture incidence in the institutionalized elderly and analysis of associated risk factors.
  
  
  METHODS
  Longitudinal and prospective study with 3-year follow-up.
  
  
  METHODS
  Old people's home in Turin for patients who are no longer self-sufficient.
  
  
  METHODS
  197 subjects (47 males and 150 females) aged between 61-98 years old, dependent in at least two basic daily activities.
  
  
  METHODS
  At the time of enrollment, the following parameters were evaluated: age, weight, height, degree of walking autonomy, bone mineral density at proximal and distal radius. The number of falls and fractures were recorded during follow-up.
  
  
  RESULTS
  A total of 46 fractures (22 femoral and 24 in other sites) were recorded with an annual incidence of 7.8%. Femoral fractures only occurred in females. The following risk factors were associated with femoral fractures: very old age (relative risk = 2.6; 95% confidence interval = 1.1-6.4), low body mass index levels (RR = 3.3; 95% CI = 1.3-8.7), low bone mineral density levels at the proximal radius (RR = 2.6; 95% CI = 1.1-6.3), autonomous walking capacity (RR = 3.7; 95% CI = 1.1-12.0) and recurrent falls (RR = 2.7; 95% CI = 1.2-6.2). The following risk factors were associated with non-femoral fractures: autonomous deambulation (RR = 5.7; 95% CI = 1.4-23.7) and recurrent falls (RR = 6.4; CI = 2.3-18.3).
  
  
  CONCLUSIONS
  Institutionalized elderly patients present numerous risk factors for femoral fractures. Fractures in other sites are only associated with risk factors that express a tendency to fall.
