Prolonged reception of cholecalcipherol – the basis of effective prevention of hypovitaminosis d in young years

Introduction. Vitamin D plays a fundamental role in the regulation of calcium and phosphorus homeostasis, and in recent decades its non-calcemic effects have been intensively studied. The aim of the work was to analyze the patterns of vitamin D availability in young children against the background of prolonged use of an aqueous solution of cholecalciferol in preventive doses. Materials and methods: 192 children of the first three years of life were examined (Arkhangelsk – 77 (40.1%), Moscow – 38 (19.8%), Stavropol – 77 (40.1%) children). Assessment of vitamin D availability was carried out by the level of serum calcidiol (25(OH)D). Based on the initial vitamin D supply, patients were divided into groups, and participants used cholecalciferol preparations for 30 days. Results. The baseline vitamin D supply was 26.0 (19.5–35.4) ng/ml. Median 25(OH)D in children in the Moscow region is higher than in Arkhangelsk and Stavropol (
