Abstract
Law enforcement officers with different levels of combat stress (men, residents of the Komi Republic, n=33, 35,0 (32,0-39,0) years old) were examined before (November) and after (March) trips to the combat zone. The control group included agents of the Ministry of emergency situations with a low level of stress (men, residents of the Komi Republic, 32.0 (30.0-35.0) years old). In total, law enforcement officers were shown to have a wide prevalence of vitamin deficiency: about 50% of persons had hypovitaminosis for vitamins A, E, about 35% - for vitamins B1, B2 and 24% - for vitamin C. A parallel study of the control group and law enforcement officers in November showed that initially there were more persons with reduced vitamin status in law enforcement officers, especially in the level of vitamins B1 and E. In March, after the arrival of law enforcement officers from the combat zone, they found a significant decrease in the percentage of persons with hypovitaminosis for vitamins A, E, C and an increase vitamin B1 deficiency. Changes vitamin status in the control group from November to March were not so significant.
