Association of vitamin D deficiency with chronic non-communicable diseases, autoimmune diseases and general mortality necessitates correcting its deficiency in all age groups in order to improve the health of the population. School-aged children need to achieve optimal levels of vitamin D due to the high growth and developmental needs. It is necessary to understand the availability of vitamin D in this age group for the implementation of measures for the deficiency prevention and correction.

Purpose: to study the provision of school-age children in Arkhangelsk with vitamin D.

Material and methods. Children aged 6 to 15 years, living in Arkhangelsk, were surveyed. The concentration of the main metabolite 25(OH)D was determined in a cross-sectional study.

Results. The study included 502 children, the recommended values ​​of the level of 25(OH)D were found in 107 (21,3%) children and adolescents, the majority (45.2%) of both younger schoolchildren and adolescents showed vitamin D deficiency. Evaluation of the diet showed the extremely low frequency of children consuming fish as the main food source of vitamin D, the frequency of taking vitamin D was 8%. There are no significant differences in vitamin D provision in various seasons.

Conclusion. Measures are needed for year-round prevention and correction of vitamin D deficiency in children and adolescents in the city of Arkhangelsk based on the recommendations outlined in the National Program «Vitamin D Insufficiency in Children and Adolescents in the Russian Federation: Modern Approaches to Correction».

Keywords: children, adolescents, vitamin D, vitamin D deficiency, 25(OH)D.
