Epidemiology of Fragility Fractures and Social Impact

Hip fracture is an important and debilitating condition in older people, especially in women. The epidemiological data vary between countries, but it is globally estimated that hip fractures currently affect around 18% of women and 6% of men. Although the age-standardised incidence is gradually decreasing in many countries, this is far outweighed by the ageing of the population. Thus, the global number of hip fractures is expected to increase. The direct costs associated with this condition are enormous since it requires a long period of hospitalisation and subsequent rehabilitation. Furthermore, hip fracture is associated with the development of other negative consequences, such as disability, depression, and cardiovascular diseases, with additional costs for society. At the same time, increasing attention is given to other osteoporotic fractures, such as vertebral ones, that are associated with negative health outcomes and enormous costs. In this chapter, we describe the most recent epidemiological data regarding hip and other osteoporotic fractures, with special attention to the well-known risk factors and conditions that seem relevant for determining fractures in older people. A specific part is dedicated to the social costs due to fractures. Although the costs of hip fracture are probably comparable to other common diseases with a high hospitalisation rate (e.g. cardiovascular disease), the other social costs (due to onset of new comorbidities, sarcopenia, poor quality of life, disability and mortality) are probably greater.
