FERNANDEZ-GARCIA, M. et al. Secular trend in the incidence of hip fractures in the world. Rev Osteoporos Metab Miner [online]. 2015, vol.7, n.4, pp.121-132. ISSN 2173-2345.  https://dx.doi.org/10.4321/S1889-836X2015000400008.

Osteoporosis is the most common metabolic bone disease and the main effector of the development of fractures in people over 50 years. When analyzing the evolution of the incidence of hip fracture it is important to consider the effects of the implementation of the strategies undertaken to prevent and treat early forms of disease and falls. In most chronic diseases with an environmental etiological component, identified or not, an interval of several decades occurs between initial exposure to the main causative agent and the clinical onset of the disease. The systematic study of the secular trend of a disease shows different phenomena that help to understand its pathogenesis. At the same time, it constitutes an activity of surveillance that allows warn about its future relevance. The evolution of the incidence rate of hip fractures has not been uniform over time in different countries. It is a matter of great interest to identify whether the observed temporal changes in rates are associated with an aging population or the result of a large number of circumstances of the same population over time. In this paper we review the main studies published around the world that explore, in greater or lesser extent, in the analysis of the secular trend in the incidence of hip fracture in order to bring this concept to the reader and offer an overview on the evolution of the incidence of hip fracture and the causes of this evolution.
