Evaluation of vitamin status of the population of the russian arctic according to the data on vitamin consumption and serum level

Aim. To compare the calculated data of A, B2, D vitamins and beta-carotene consumption with diets and biomarkers of vitamin status of 178 residents of Tazovsky and Gyda settlements of Yamal-Nenets Autonomous Area. 
Materials and Methods. The actual nutrition was studied by frequency (according to the frequency of food consumption for the previous month) and 24-hour (daily) reproduction methods. Vitamin status was assessed by serum vitamin concentration. 
Results. A statistically significant relationship between serum beta-carotene level and its consumption with rations was established. There was no significant relationship between the level of fish consumption and vitamin D sufficiency. 
Conclusion. Vitamin intake data provide a framework to reveal deviations from optimal nutrition and to identify risk groups with vitamin deficiency, but they do not always make it possible to carry out an objective assessment of individual vitamin sufficiency. Thus, in individuals with a clear lack of vitamin A in the diet on the previous day before taking blood, blood retinol level was in the normal range.
