The impact of selected metallic elements in the environment on the occurrence of osteoporosis in the voivodeship of Silesia.

Background. The existence of toxic metallic elements in the environment is one of the most important factors influencing the metabolism of calcium. The aim of our study was to compare the incidence of osteoporosis in Upper Silesia to the level of environmental pollution with lead, cadmium, zinc, and copper. Material and methods. An epidemiological data base gathered by the Silesian Branch of the National Health Fund was used to gather data concerning the incidence and treatment of osteoporosis in Silesia, with and without pathological fractures. Results. The results of our analysis suggest that the frequency of osteoporosis, with or without pathological fractures both, correlates with increased concentrations of lead, cadmium, copper and zinc in the environment. This relation can be noticed especially in the Upper Silesian Industrial District. Conclusions. In regions with increased risk due to the occurrence of significant amounts of heavy, osteotropic elements, programs should be implemented to intensify screening for osteoporosis.
