Changing trends in the epidemiology of hip fracture in Spain

Summary Temporal trends in hip fracture incidence have recently been reported in some developed countries. Such data in Spain has previously been incomplete; this study reports the stratified incidence of hip fractures in people over 65 in Spain during the last 14 years. Introduction The main objective is to establish whether temporal trends in hip fracture incidence in Spain exist. Methods Ecological study with data from hospital discharges nationwide. The study includes patients aged ≥65 years during a 14-year period (1997–2010). The analysis compares two periods of four years: 1997–2000 (P1) and 2007–2010 (P2). Results There were 119,857 fractures in men and 415,421 in women. Comparing periods (P1 vs P2) over 10 years, the crude incidence rate/100,000 inhabitant/year increased an average of 2.3 %/year in men and 1.4 % in women. After adjustment, the rate increased an average of 0.4 %/year in men ( p
