title: [Incidence of hip fracture in Spain (1997-2010)].
abstract: OBJECTIVE
  To analyse differences in the incidence of hip fracture in people older than 65 years in the 17 autonomous communities (AA. CC.) (regions) of the Spanish state in the 1997-2010 period.
  
  
  METHODS
  Ecological, observational and retrospective study that includes people≥65 year old who have suffered a hip fracture in Spain over 14 years. These records are taken from the minimum basic data set of patients treated in all hospitals of Spain.
  
  
  RESULTS
  The analysis include 534,043 hip fractures in≥65 year olds (414,518 women and 119,525 men). A percentage of 85.4 of hip fractures occurred in people≥75 years (86.7% women; 80.7% men). The adjusted hip fracture rate/100,000/year was 722.6 in women and 284.8 in men. AA. CC. with women above the average of the country were 7, including Catalonia, Comunidad Valenciana and Castilla-La Mancha. Six AA. CC. had patients below the average, including Canary Islands and Galicia. In AA. CC. with highest and lowest adjusted hip fracture rate/100,000/year, the difference was 44% lower in women (Canary vs. Castilla-La Mancha) and 50% lower in men (Galicia vs. Catalonia).
  
  
  CONCLUSIONS
  The analysis of the incidence of hip fracture in Spain in people≥65 year old shows a significant variability between AA. CC. Except in Canary Islands, this variability is difficult to explain only by factors such as population age, sun exposure or north-south gradient. Additional studies are needed to analyse the causes of these important differences between Spanish AA. CC.
