LEVELS OF MAGNESIUM AND CALCIUM IN THE BLOOD SERUM OF RESIDENTS IN ONE OF RUSSIA'S REGIONS
In order to establish the level of magnesium and calcium supply in Chuvashia residents, we analyzed their serum concentrations, which were obtained during blood donation during routine medical examination or by a doctor's referral. 2152 serum samples were analyzed for magnesium (1429 women and 723 men) and 1324 (908 and 416 women and men, respectively) - for calcium. There were no differences in the levels of chemical elements in blood serum neither between males and females, nor between people of different ages (the following age intervals were taken into account: 20-39 years, 40-59 and 60-79). The highest percentage of test results with a magnesium content of less than 0,70 mmol / l is observed in the group of people with diseases of the digestive system. Moreover, this feature was typical for both women and men (7,19 and 13,58%, respectively). The smallest number of magnesium and calcium samples with results below the reference values in our study was found in the group of examined women with circulatory system diseases, and in the group of men - with endocrine system diseases. These results, expressed as a percentage, were significantly lower than the same indicator obtained when evaluating the elemental composition of blood serum in the total sample, taking gender into account. It is concluded that it is necessary to monitor and correct the nutrient imbalance with preparations containing magnesium and calcium, especially in persons with diseases of the digestive system.
