This report presents information about the prevalence and impact of osteoporosis in Australians aged 50 and over. A broad range of data sources show that osteoporosis prevalence markedly increases with age and is more common in women than in men. Osteoporosis is one of several risk factors for minimal trauma fracture, with minimal trauma fracture of the hip being one of the most serious possible outcomes of osteoporosis. Although the rate of minimal trauma hip fracture for people aged 50 and over has decreased over the last ten years, the number of hip fractures continues to increase due to the increasing number of older adults in Australia.
