Assessment of the actual dietary intake of micronutrients in fertile women living in the north of the Tumen region

Objective. To assess the dietary intake of vitamins А, Е, С, D and such bioelements as iron, manganese, calcium, magnesium, copper, zinc and selenium in fertile women living in the north of the Tyumen region.
Patients and methods. We examined 157 women of reproductive age (18–44 years), who had been living in the administrative centres of the north of the Tyumen region – the cities of Khanty-Mansiysk (n = 75) and Salekhard (n = 82) – for more than 5 years, and were not employed in the industrial sphere. The computer program «ASPON-nutrition» was used to analyse the dietary intake of micronutrients: vitamins А, Е, С, D and bioelements: Fe, Mn, Ca, Mg, Cu, Zn, Se. The results were compared with the recommended allowances (RA).
Results. We have found an inadequate dietary intake of vitamins Е (77 % RA), С (75 % RA), D (55 % RA) along with overconsumption of vitamin А (119%). The optimal levels of intake of Fe (102% RA) and Mn (100% RA) were combined with dietary deficiencies of Са (67% RA), Mg (87% RA), Cu (68% RA), Zn (88% RA) and, especially, Se (49% RA). 
Conclusion. We have found an inadequate dietary intake of antioxidant vitamins Е, С and bioelements that make part of antioxidant enzymes Se, Cu, Zn, closely linked with metabolism of fat-soluble antioxidant vitamins А and Е, and Са, vitamin D, and also bioelements Mg and Са, vital for the optimal functioning of the cardiovascular system. In order to prevent the development of diseases associated with the inadequate intake of micronutrients by the population of the North, it is necessary to optimise nutrition, include food supplements and use food products fortified with vitamins and bioelements.
