Abstract
The paper gives an update on the biological role of vitamin D in the human body, its metabolic pathways, and potential abnormalities resulting in reduced provision.
Objective: to determine vitamin D provision in the children of Kazan during the winter season.
Examinations were made in 309 children, including 171 infants aged 1 month to 3 years and 138 children 6 to 18 years of age. Serum 25(OH)D levels were determined by chemiluminescence immunoassay at the EFiS Research Center (Moscow). In infants under 3 years of age, the mean 25(OH)D values were 18,2±1,0 ng/ml, while only 14,8% of the patients were found to have normal 25(OH) D values of (more than 30 ng/ml) and the rest had vitamin D metabolite insufficiency or deficiency. The winter vitamin D level was consistent with the normal ones in 11,2% of the schoolers, lower in 122 (88,8%) children; the provision of vitamin D was at its deficiency level (less than 10 ng/ml) in 33 (24%) children. The findings suggest that it is necessary to prescribe vitamin D for all children under the age of 18 during winter and autumn. It is best to determine the initial level of the metabolite and to use its dose corresponding to that of vitamin D.
