Osteoporosis, fractures, and mortality – individual and social determinants

Are Norwegians more fragile than other populations? Why is one of four hip fracture patients dead one year after the incident? These are among our study questions in this project.

About the project

Hip fracture is the most serious consequence of osteoporosis, both on an individual and social level, and associated with substantial excess morbidity and mortality.  Norway has among the highest rates of hip fracture in the world, but the impact of this condition on society has been given little attention.  Over the next 30 years, the population above 65 years in Norway is expected to double. As osteoporotic fracture risk increases steeply with age, an increased fracture burden is likely.


The objective is to explore possible causes and consequences of osteoporotic fractures on an individual, regional and social level.


The high hip fracture incidence in Norway combined with good registers enable novel studies of this serious condition. Information on hip fractures treated in Norwegian hospitals between 1994 and 2008 is available together with information on socio-economy, cause of death, Person Register status, and information from health surveys in subgroups. Data on the total Norwegian population is available from Statistics Norway. Moreover, in collaboration with the University of Aalborg we are planning comparative and/or combined data analyses of Norwegian and Danish hip fracture data.

By linking the different data sources and employing statistical models we can explore a number of possible causes and consequences of hip fracture.
