Trace Element Levels in Children and Adolescents from Selected Regions of Slovakia
Essential trace elements, zinc, copper and selenium, are important for optimal function of specific biochemical reactions. They influence the immune system and as a component of enzymes, they are involved in redox reactions. They may be important in development of cardio-vascular diseases and cancer. This hypothesis is supported by results of epidemiological and ecological studies. Increased levels of zinc and copper were observed in women with breast cancer (1,2), in lung cancer and in and stomach cancer (3). Increased levels of copper increase the risk of cardio-vascular diseases (CVD) (4,5). Similarly, decreased values of selenium under 0.57 μmol/L represent a risk for development of cancer and or CVD (6–9). Aim of this study was to obtain serum levels of zinc, copper and selenium in our children and adolescent population, and to assess the possible risk.
