[Seasonal variations of vitamin sufficiency in pregnant women (Mzensk City)].

The investigation of sufficiency of vitamin C, A, E, B2, B6, carotenoids and iron dietary intake has been carried out in 61 pregnant women in spring and early autumn 1998. There were no women adequately supplied with all vitamins irrespective of season and residence. Most of them (70-80 per cent) had combined deficiency of 3-5 vitamins in spring. About 50 per cent of women had combined insufficiency of vitamins and iron. Intake of vitamins improved in autumn especially due to vitamins C, A, E and carotenoids. The frequency of 3-5 vitamins deficit decreased while occurrence of combined deficiency of vitamin B6 and carotenoids still often took place. Thus, normalization of vitamin status of pregnant women is necessary all year round.
