Global vitamin D status problems: causes, pathogenetic mechanisms, treatment, prevention measures

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. The diet of adolescents is an important factor in their future health. The diet is formed under the influence of biological, personal, family, socio-economic, environmental, and cultural factors.The aim: to study the diet of adolescents in rural areas of Buryatia and compare the dietary intake of the Russian and Buryat ethnic groups.Materials and methods. The study included 92 rural adolescents 11–17 years old (44 boys, 48 girls); 49 of them were Buryats, 43 – Russians. Dietary intake was assessed by the food record method. The intake of energy, macronutrients (proteins, fats and carbohydrates) and micronutrients (major groups of vitamins and trace elements) of the diet was determined. The values obtained were compared with references to daily energy and nutrient intake, and between groups of adolescents of different ethnicity.Results. The diets of rural adolescents were not balanced. Only 7.6 % of adolescents include fish in their diet. Milk and dairy products are consumed by 38 % of the respondents. Daily energy intake was significantly lower the recommended guidelines. The diet is characterized by a deficiency of vitamins of groups A, C, and D, group B (with the exception of cobalamin), niacin, biotin, essential trace elements (calcium, phosphorus, iodine), high sodium intake. A significant deficiency of dietary fiber has been noted. The Buryats showed a shift in the ratio of proteins, fats and carbohydrates in the diet towards carbohydrates (1 : 1.2 : 5.3).Conclusion. The results indicate significant disturbances in the composition of the diet in rural adolescents in Buryatia, more pronounced in the Asian subgroup. This can be a rationale for the development of targeted nutrition monitoring programs aimed at preserving the health of the youth.
