[Effectiveness of use in preventive nutrition the food ptoducts with contents of pectin and vitamins].

Daily inclusion in the diet of Pskov GRES workers the drinks or kissels containing 2 g pectin per daily serving (cup) during 6 months was accompanied by a statistically significant decline of their supply with vitamins C, B2, A and beta-carotene. This is reflected both in reducing the average vitamin concentration in blood serum and in the increase of the quota of people with deficiency of several vitamins. Additional inclusion of 13 vitamins in these drinks and kissels, in a dose about 80% of the RDA, has prevented the deterioration of vitamin status.

[Effect of vitamin beverages on vitamin sufficiency of the workers of Pskov Hydroelectric Power-Plant].

The research of influence of vitamin complexes in the form of a drink or kissel on vitamin sufficiency of working persons has been carried out. Long inclusion (6,5 months) in a diet of vitamin drinks containing about 80% from recommended daily consumption of vitamins, was accompanied by trustworthy improvement of vitamins C and B6 sufficiency and prevention of seasonal deterioration of beta-carotene status. As initially surveyed have been well provided with vitamins A and E, their blood serum level increase had not occurred.

[The influence of age and sex on fat- and water-soluble vitamins sufficiency of adulthood].

Serum concentrations of vitamins A, B2, B6, C, E and beta-carotene were determined in 174 healthy individuals ages 22-59 years. It was been shown that only 11% of examined men and 24% of women were well provided with all vitamins-antioxidants and beta-carotene. 38% cent of women and 67% cent of men had the combined insufficiency of 2-3 antioxidants (more often of vitamin C, B2 and beta-carotene). Men presented significantly higher serum retinol concentrations and lower concentrations of vitamin C and beta-carotene--than women. Serum concentrations of retinol for women and tocopherols for both men and women increased by 0.3% and 0.4% per year, respectively.

[Analysis of vitamin and mineral sufficiency in children using data of consumption with food and urinary excretion]. / Otsenka obespechennosti detei vitaminami i mineral'nymi veshchestvami po dannym o postuplenii ikh s pishchei i ékskretsii s mochoi.

It has been shown that vitamin C and B2, calcium and phosphorus daily intake strongly correlated with their urinary excretion in children 5-8 years old (Moscow) from the decreased bone mineral density risk group. Hour urinary calcium, phosphorus, creatinine excretion values for adequately supplied children has been determined. Vitamin and mineral status evaluation by means of estimation of vitamins and minerals consumption and urinary level (except vitamin B2) give relatively coincided results. Difference between these methods of nutritive status assessment attains 8-25 per cent. Thus these methods are substituted for group nutritive status evaluation.

[Vitamin sufficiency to preschool and young school age children from a group at risk for emergence of bone mineralization disorders]. / Obespechennost' vitaminami detei doshkol'nogo i mladshego shkol'nogo vozrasta iz gruppy riska po vozniknoveniiu narushenii mineralizatsii kostnoi tkani.

Vitamin status of 36 children 5-8 years old (Moscow) from the decreased bone mineral density risk group has been evaluated. Only 6-14 per cent of children had deep vitamin deficit. Vitamin B1 and B2 insufficiency has been observed 1.6 fold rarely among children additionally receiving vitamin supplement. The relation between urinary calcium and vitamins B1, B2 and B6 excretion has been shown. No difference was found in calcium excretion rate irrespective of additional vitamin intake. Although no correlation between urinary calcium/creatinine excretion and urinary vitamins C, B1, B2 and B6 excretion has been found children with increased calcium/creatinine index are insufficiently supplied with four vitamins more often. The data obtained could not be regarded as negation of the vitamin sufficiency importance for calcium metabolism and osteogenesis disturbance prevention.

[The vitamin C, B12 and folate allowances of pregnant women in Moscow]. / Obespechennost' beremennykh zhenshchin Moskvy vitaminami C, B12 i folatom.

A dietary supply of vitamins was studied in 212 pregnant women for 11 months. Mean blood levels of vitamins were found subnormal, the percentage of the women with vitamin deficiency increased. Especially inadequate was supply of folate followed by vitamin C. Intake of 1 dragee a day of polyvitamins "Gendevitum" improved the vitamin status of the examinees with the best results obtained in the first trimester. Folate and B12 levels decreased with advance of pregnancy irrespective of polyvitamins administration. Vitamin C supply was better in summer and autumn, folate levels were higher in winter and spring. It is suggested that vitamins C, B12 and folate deficiency observed in pregnancy should be corrected.
