Analysis of risk factors for vitamin D deficiency by results of the first stage of Russian non-interventional register study

Abstract

Introduction. In Russian Federation, there are no comprehensive studies assessing the quality of life and risk factors for vitamin D deficiency and insufficiency, taking into account its status in different geographic latitudes.Aim. To assess the quality of life and risk factors for 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 “cross-sectional” method was carried out from March 2020 to May 2020.Results and discussion. According to the results of the correlation analysis, qualitative and quantitative factors were identified, presumably being risk factors for vitamin D deficiency and deficiency. Qualitative risk factors include: education; alcohol consumption; being in direct sunlight for more than 30 minutes a day; visit to the solarium; using sunscreen; drinking coffee; taking medications (not vitamin-mineral complexes). Quantitative factors include: visits to specialists (total per year); smoking (duration, years); exercise for more than 30 minutes a day, once a week; being in direct sunlight for more than 30 minutes a day.Conclusion. A wide range of risk factors for vitamin D deficiency dictates the need for their further study to clarify the category of persons who are shown targeted biochemical screening with subsequent drug correction.
