Summary
Osteoporotic fractures are associated with increased morbidity and mortality. Anti-osteoporosis medications reduce re-fracture and possibly morality, yet osteoporosis is poorly treated. This study will link information from >260,000 people (45&Up study) with hospital admissions, medications and deaths to create the largest, detailed dataset of its kind. We will be able to determine cause of any fracture-associated mortality and the effect of medication to improve osteoporosis management.

Summary
Osteoporotic fractures are a common and increasing problem as the population ages. They are associated with increased risk of re-fracture and early death yet most patients remain untreated. This proposal will identify which fracture patients are at highest risk of re-fracture and premature death (b) identify whether osteoporosis treatment decreases this risk and (c) increase osteoporosis awareness and treatment uptake by general practitioners with an integrated fracture risk prediction tool.

Summary
Osteoporosis is a condition characterised by excessive bone loss and impaired bone quality, which ultimately results in fracture with minimal trauma. Osteoporosis affects 27% of women and 11% of men aged 60 years or above in the community, and costs Australia around $7 billion each year. Individuals with low bone mineral density (BMD) have a significantly higher risk of fracture than those with normal BMD. In the long-term (14-year) Dubbo Osteoporosis Epidemiology Study, more than half of indivi ....Osteoporosis is a condition characterised by excessive bone loss and impaired bone quality, which ultimately results in fracture with minimal trauma. Osteoporosis affects 27% of women and 11% of men aged 60 years or above in the community, and costs Australia around $7 billion each year. Individuals with low bone mineral density (BMD) have a significantly higher risk of fracture than those with normal BMD. In the long-term (14-year) Dubbo Osteoporosis Epidemiology Study, more than half of individuals with osteoporosis (e.g., low BMD) did not sustain a fracture, while approximately 60% of fracture cases had BMD above the high risk levels. Thus, BMD alone is not a good discriminant of fracture versus non-fracture cases. It is widely known that the liability to fracture is determined in part by genes. Previous studies, including from our group, have suggested a number of candidate genes that are associated with fracture risk. The fundamental issue that this study is concerned is that how and whether genetic markers could be used to facilitate case finding. It is proposed that common variations of certain genes are associated with fracture risk independent of BMD. That is, they can identify individuals at relatively high and low fracture risk after stratification for BMD. Hence, some markers may identify those individuals likely (and unlikely) to fracture even with low (osteoporotic) BMD. Similarly, some, possibly the same, markers may identify individuals at high risk of fracture despite relatively good (ie non-osteoporotic) BMD. It is further proposed that no single gene will achieve this outcome, but rather a small set of such gene polymorphisms will provide clinically useful risk information. This effect is entirely analogous to the use of clinical risk indicators (eg, age, weight, sex, family history, etc) to assess the risk of future fracture.Read moreRead less
The overall aim is to improve treatments and outcomes for people with osteoporosis. This will be achieved by better predicting those who are likely to fracture and subsequently those who do well post fracture from those who do poorly. Following an osteoporotic fracture there is an increased risk of re- fracture and of premature death. This research will define those risk factors for fracture, re-fracture and early death in a large group of men and women followed for over 20 years.
