UNLABELLED: Hip fracture incidence rates in Austria over a period of 20 years (1989-2008) were assessed. Age-standardized incidence rates increased until 2005 but decreased thereafter. This change in the secular trend was primarily driven by a decrease in hip fracture incidence in women. INTRODUCTION: The aim of the prevailing study was to assess the incidence rates of hip fractures including changes in trend in the Austrian population over a period of 20 years (1989-2008). METHODS: The number of hip fractures was obtained from the Austrian Hospital Discharge Register for the entire population ≥ 50 years of age. A correction factor for multiple registrations of the same diagnosis was determined. Incidence rates (cases per 100,000) of hip fracture were calculated in 5-year age intervals. To analyze the overall change in hip fracture for the period, average annual change expressed as incidence rate ratios (IRRs) was calculated. RESULTS: The age-standardized incidence in women increased until 2005, from 493 to 642, and decreased thereafter. In men, it increased at a measured pace until 2006, from 192 to 280, and decreased thereafter with a slight rebound in 2008. The age-standardized incidence in the entire population increased until 2005, from 376 to 496, and decreased thereafter. The IRR for the last 3 years (2006-2008) was significantly below the IRR for the first 17 years (0.94, ρ < 0.01), driven by a lower IRR in women (0.91, ρ < 0.01) and to a lesser extent by a lower IRR (not statistically significant) in men (0.96, ρ < 0.15). CONCLUSION: The present study indicates that since 2006, age-standardized incidence of hip fractures has been declining in the Austrian population aged 50 years and above. This reversal in the secular trend has primarily been driven by a decrease in hip fracture incidence in women.
