[Providing with vitamins of different population groups in Sverdlovsk].

The investigation on providing with vitamins of varying population groups: preschool children, schoolchildren, students of trade schools and higher schools, workers and employees was conducted in Sverdlovsk. Low levels of vitamin C were detected in the blood of 40-92%, folic acid--in 10-76%, vitamin A--in 4-28%, carotene--in 8-60%, tocopherol--in 4-50% of the examinees. Vitamin B1 deficiency was noted in 36-68%, vitamin B2--in 17-71%. The highest deficiency of ascorbic acid was recorded in workers and students of trade schools and higher schools, of folic acid--in workers and adolescents of 15-18 years, of vitamins B1, E, A and carotene--in children and adolescents, vitamin B1--in employees. The mass character of vitamin deficiencies and their negative effects on the health of the population have necessitated broad-scale prophylactic measures: production of vitamin-enriched foods, regular use of multivitamins.
