RESUMEN
It has been shown that there is an association between air pollution and cardiovascular mortality. In bone pathology, studies show that air pollution is associated with a risk of developing osteoporosis and osteoporotic fracture associated with MP2.5 and nitrogen dioxide (NO2 ). The aim of our study was to determine whether or not there is an association between air pollution and osteoporotic disease, associating the incidence of femoral neck fracture in individuals aged 50 years or more and the contamination present in the several cities. Our results showed no statistically significant association between air pollution, evaluated using PM10 and PM2.5 as indicators, and the average annual incidence of osteoporotic hip fracture, comparing the most polluted cities and the less polluted cities of Chile
