Supply of mineral substances to the adult population of the Western Siberia region

Aim. Hygienic assessment of mineral deficiencies among the adult population of Western Siberia. Materials and methods. The supply of minerals to the adult population of the Omsk region was assessed in a cross-sectional descriptive observational study based on the content of 24 elements in human hair in a random quota sample that included 333 people (151 men and 182 women). Results. In 69.7 ± 2.5 % of the adult population of the Omsk region, disturbances in the supply of mineral substances were noted. Among the most common deficiencies were zinc (32.4 ± 2.6 %), selenium (29.7 ± 2.5 %), copper (26.8 ± 2.4 %), magnesium (26.2 ± 2.4 %), iron (23.9 ± 2.3 %), silicon (16.8 ± 2.1 %), calcium (15.9 ± 2.0 %), potassium (15.9 ± 2.0 %), and molybdenum (11.4 ± 1.7 %). An increased content of toxic and potentially toxic mineral substances in the body was noted for such substances as aluminum (32.8 ± 2.6 %), cadmium (31.2 ± 2.5 %), and lead (10.1 ± 2.5 %). The elemental status in men and women, as well as in the age groups of 18–29 years, 30–44 years, 45–64 years, 65 and more years was determined. The frequency of mineral deficiencies increased with age for such elements as magnesium, iron, and selenium. Conclusion. In comparison with 2007–2010, a tendency towards a decrease in the frequency of mineral deficiency in the adult population of the region was observed. In 69.7 ± 2.5 % of the adult population of the Omsk region, disturbances in the supply of mineral substances were noted, with their frequency increasing with age and being more common in men.
