Vitamin status of adult population of the Russian Federation: 1987-2017

Abstract

In a review in order to characterize the dynamics of vitamin status for the period from 1987 to the present, the results of 16 surveys (conducted in 2015-2017) of the sufficiency with vitamins C, A, E, B2 and B6 of adult men and women of working age (about 1200 peo­ple) living in different regions of the Russian Federation, were compared with the frequen -cy of vitamin insufficiency among the population in the previous period. The statistically significant improvement in the population's supply with vitamin C in the previous decade continued in 2015-2017. The deficit of this vitamin practically ceased to occur. Reduced blood serum levels of vitamin A were rare (except for patients with tuberculosis, the indigenous inhabitants of an inaccessible village beyond the Arctic region, and pregnant women, especially in the third trimester). In comparison with the previous period, a fairly rare occurrence of vitamin E deficiency persisted. Vitamin B2 deficiency was still detected in a significant number of subjects (25-75th percentile was at the level of 30-50%) and was encountered approximately at the same frequency as in the previous period. The lack of B vitamins in the adult population was still much more common than the deficiency of vitamins A, E and C. The incidence of the combined deficiency of three or more vita­mins (including, in addition to vitamins C, A, E, B2 and β-carotene, vitamins D, В6, В12, folates) currently ranged from 5 to 39%. In this same range was the frequency of obser­vation of persons sufficiently supplied with all studied vitamins. To improve the vitamin supply of the population, the urgent need for legislative consolidation and/or adoption of normative acts regulating compulsory enrichment of food products of mass consump­tion (bread and milk) with vitamins D and B group has arisen.
