Hygiene assessment and dietary correction of vitamin D level in residents of the southern region of Ukraine

For most people, the best way to prevent vitamin D deficiency is to optimize your diet by using foods high in vitamin D. Adding foods high in vitamin D that are available in your area to your diet is a physiological way to prevent vitamin D insufficiency and deficiency. Which in turn, is an effective way to prevent the development of pathological conditions associated with a low level of vitamin D. Objective: To determine the level of prevalence of vitamin-D deficient states among residents of the southern regions of Ukraine. To assess the relationship between deficiency and insufficiency of vitamin D with actual nutrition and to develop recommendations for the prevention of such conditions. Materials and methods. 928 residents of the Southern region of Ukraine, aged from 19 to 82, were examined. The study consisted of two stages: assessment of the diet and determination of the level of 25(OH)D in the blood serum and dietary correction of the diet in patients with vitamin D < 30 ng/ml, by enriching the diet with products with a high content of vitamin D. The results of the study and their discussion: The level of 25(OH)D among the study participants was 4.31 – 89.19 ng/ml. Vitamin D was deficient in 312 patients, insufficient in 290 patients, and sufficient in 326 patients. 114 patients took part in the second stage of the study: The main group (n=63) – correction of vitamin D by enriching the diet with products containing vitamin D equivalent to 4000 IU/day. Control group (n=51) - correction of 25(OH)D level was not carried out. Conclusions. Vitamin-D deficient conditions are common among residents of Southern Ukraine. Correction of the diet due to products with a high content of vitamin D in an equivalent dose of 4000 IU/day is able to ensure a sufficient level of 25(OH)D in the blood serum.
