Aim: To assess the incidence of vitamin D deficiency and insufficiency among the adult population living in the regions of the Russian Federation located at latitudes from 45 to 70., Materials and Methods: Russian multicenter non-interventional registry study using the "cross-sectional" method., Results: In this study, 72.1% of the examined have the status of vitamin D deficiency and insufficiency, while an adequate level was diagnosed in 27.8% of cases. When assessing the degree of vitamin D deficiency depending on the season, statistically significant differences (p0.00001) were found between the periods: vitamin D deficiency or insufficiency was observed in 84.2% of autumn and in 62.4% of spring. The highest incidence of vitamin D deficiency and insufficiency was recorded in males compared with females (p=0.013, 79 and 70.3% respectively). Vitamin D deficiency is observed in young people in the age subgroup of 1825 years (p0.001, 54% in the study as a whole) much more often than in older people Conclusion. The widespread high prevalence of vitamin D deficiency in the Russian Federation is not related to geographic region of residence, but to some extent depends on the season. The high-risk group for vitamin D deficiency and insufficiency is young men. The significant role of vitamin D in the human body justifies the need to supplement and clarify a single concept for the prevention, diagnosis and treatment of conditions associated with deficiency, so higher implementation of National Clinical Guidelines is needed.

Background: In Russian Federation, there are no large-scale cross-sectional multicenter epidemiological studies assessing the prevalence of vitamin D deficiency and insufficiency in different geographical latitudes. Insufficient solar insolation and inadequate vitamin D content in food dictate the need to study the epidemiological structure of low vitamin D status in Russia., Aim: To assess the incidence of vitamin D deficiency and insufficiency among the population living in the regions of the Russian Federation located at latitudes from 45 ° to 70 °., Materials and Methods: The first stage of the Russian multicenter non-interventional registry study using the «crosssectional» method was carried out from March 2020 to May 2020., Results: In regions that represent a geographically representative sample of regions of the Russian Federation with a high risk of developing low levels of vitamin D, it's deficiency was noted in 55.96%, and the level of deficiency and insufficiency was recorded in 84.01%., Conclusion: Close attention to the wide scale of the problem of vitamin D deficiency and insufficiency in the Russian Federation will contribute to the progressive formation of various educational and preventive programs necessary to strengthen health and improve the quality of life of the population.

Calcium and vitamin D are essential micronutrients, whose deficiency adversely affects not only bone health, but also the functioning of the whole organism. The aim of this study was to explore the level of calcium and vitamin D intake in the adult population of the Tyumen region, in order to optimize the nutritional program. Material and methods . The study included 440 people living in Tyumen and Tyumen region. Inclusion in the study was conducted on the principle of random sampling using a random number program. The questionnaire was used to estimate the consumption of calcium and vitamin D with food. Serum level of 25(OH)D was determined in all participants of the study, the analysis was carried out by ELISA using Sunrise Euroimmin 25-OH Vitamin D ELISA test systems. Results and discussion . The results of our own data led to the conclusion that there were a lack of consumption of foods rich in vitamin D among all ages and inadequate intake of calcium, especially in the older age groups. Approximately half of the respondents rarely ate sea fish, which was interrelated with plasma levels of 25(OH)D - vitamin D deficiency was detected in 70.7%, and its insufficiency was recorded in 22.0% of those examined. Only 45.5% of respondents consumed dairy products daily, while in general there was deficit of calcium intake in all age groups compared with the average age norm. Conclusion . Adequate compensation of chronic calcium and vitamin D deficiency, which is widespread in both the Russian Federation and the Tyumen region, is an extremely important preventive direction of modern medicine., Competing Interests: The authors declare no overt and potential conflict of interest related to the publication of this article., (Copyright© GEOTAR-Media Publishing Group.)
