PROVISION OF FAT-SOLUBLE VITAMINS IN THE BODY OF THE ADULT POPULATION OF RESIDENTS OF SAINT PETERSBURG
Abstract
Introduction. Nutrition makes the greatest contribution to ensuring human health and performance from the sum of all factors affecting lifestyle. The aim of the study is to assess the provision of fat-soluble vitamins in the body of adult residents of St. Petersburg of different genders and ages. Materials and methods. The objects of the study were 816 residents of St. Petersburg of different genders and ages, in whom, from 2018 to 2023, fat-soluble vitamins were determined in blood plasma on the basis of the chromato-mass-spectrometry laboratory of the Department of Bioindication of Center for Emergency and Radiation Medicine named after A.M. Nikiforov. The following age and sex groups were identified: men and women 18–29 years old, 30–44 years old, 45–64 years old. Chromatography-mass spectrometric determination of the concentration of fat-soluble vitamins (A, E, D3) in blood plasma was performed. Results. In women, compared with men, there was a statistically significant decrease in vitamin E levels by 29 %, vitamin A by 17 % and an increase in vitamin 25-OH-D3 levels by 18 %. The greatest deficiency in the body of residents of St. Petersburg of different genders and ages was revealed in the content of vitamin 25-OH-D3 (48 %) and vitamin E (27 %). At the same time, women had a greater deficiency of vitamin E (44%) and vitamin A (14 %) compared to men, and men had a greater deficiency of vitamin 25-OH-D3 (53 %). Conclusions. The data obtained indicate a pronounced deficiency of vitamin 25-OH-D3 and a moderate deficiency of vitamin E in the body of residents of St. Petersburg of different genders and ages. At the same time, women had a greater deficiency of vitamin E and A compared to men, and men had a greater deficiency of vitamin 25-OH-D3. The replenishment of fat-soluble vitamins, especially vitamin 25-OH-D3, can become an important additional method of disease prevention in residents of St. Petersburg.
