REAL INTAKE AND PROVISION WITH VITAMINS AND CALCIUM IN OSTEOPOROSIS: ASSESSMENT BY MEASURING INTAKE AND PLASMA CONCENTRATIONS

Abstract

Aim: To assess the providing an organism with vitamins (А, В2, С, Е), β-carotene, and calcium in osteoporosis patients by measuring their intake and plasma concentrations. Materials and methods: 108 pairs “osteoporosis patient – healthy volunteer” aged 64.29±9.73 years were formed using a “case-control” method. Real intake of vitamins and calcium was studied defining the frequency of food taking for a month using questionnaire method. Daily intake of vitamins А, В2, С, Е, β-carotene, and calcium was calculated based on the analysis of the frequency of food taking. Among the basic group, using randomized method, 60% of osteoporosis patients were selected who underwent definition of plasma levels of vitamins А, В2, С, and Е. The same study was performed in 60 control volunteers. Results: Correlation of the intake of vitamins A, C, and β-carotene with their plasma levels wasn’t noted. It may reveal an increased need in these nutrients in osteoporosis. According to the calcium intake, every osteoporosis patient can be attributed to a population category with deep insufficiency of calcium intake (less than 500 mg a day). Conclusion: The data obtained need further investigation and, first of all, in clinical and biochemical fields (enzymatic non-provision for calcium uptake, clinical manifestations of insufficient provision with nutrients). Solution of these problems would enable regulation of food intake concerning calcium uptake in osteoporosis.
