В Российской Федерации отсутствуют широкомасштабные одномоментные многоцентровые эпидемиологические исследования, оценивающие распространенность дефицита и недостаточности витамина D в различных географических широтах. Недостаточный уровень солнечной инсоляции и неадекватное содержание витамина D в продуктах питания диктуют необходимость изучения эпидемиологической структуры низкого статуса витамина D в России.ЦЕЛЬ. Оценить частоту дефицита и недостаточности витамина D среди населения, проживающего в регионах Российской Федерации, расположенных в широтах от 45° до 70°.МАТЕРИАЛЫ И МЕТОДЫ. Проведен первый этап российского многоцентрового неинтервенционного регистрового исследования по методу «поперечных срезов» с марта 2020 по май 2020 гг.РЕЗУЛЬТАТЫ. В регионах РФ, которые представляют собой репрезентативную с географической точки зрения выборку с высоким риском развития низкого уровня витамина D, его дефицит отмечен в 55,96%, а уровень дефицита и недостаточности регистрируется в 84,01%.ЗАКЛЮЧЕНИЕ. Пристальное внимание к широкому масштабу проблемы дефицита и недостаточности витамина D в РФ будет способствовать прогрессивному формированию различных образовательных и профилактических программ, необходимых для укрепления здоровья и улучшения качества жизни населения.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>витамин D</kwd><kwd>распространенность</kwd><kwd>эпидемиология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vitamin D</kwd><kwd>prevalence</kwd><kwd>epidemiology</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовом обеспечении компании АО «АКРИХИН» № AQ-01/20, версия 2.0 от 25 февраля 2020 г.</funding-statement></funding-group></article-meta></front><back><ref-list><ref id="cit1"><element-citation><name><surname>Gaksch</surname> <given-names>Martin</given-names> </name> <name><surname>Jorde</surname> <given-names>Rolf</given-names> </name> <name><surname>Grimnes</surname> <given-names>Guri</given-names> </name> <name><surname>Joakimsen</surname> <given-names>Ragnar</given-names> </name> <name><surname>Schirmer</surname> <given-names>Henrik</given-names> </name> <name><surname>Wilsgaard</surname> <given-names>Tom</given-names> </name> <name><surname>Mathiesen</surname> <given-names>Ellisiv B.</given-names> </name> <name><surname>Njølstad</surname> <given-names>Inger</given-names> </name> <name><surname>Løchen</surname> <given-names>Maja-Lisa</given-names> </name> <name><surname>März</surname> <given-names>Winfried</given-names> </name> <name><surname>Kleber</surname> <given-names>Marcus E.</given-names> </name> <name><surname>Tomaschitz</surname> <given-names>Andreas</given-names> </name> <name><surname>Grübler</surname> <given-names>Martin</given-names> </name> <name><surname>Eiriksdottir</surname> <given-names>Gudny</given-names> </name> <name><surname>Gudmundsson</surname> <given-names>Elias F.</given-names> </name> <name><surname>Harris</surname> <given-names>Tamara B.</given-names> </name> <name><surname>Cotch</surname> <given-names>Mary F.</given-names> </name> <name><surname>Aspelund</surname> <given-names>Thor</given-names> </name> <name><surname>Gudnason</surname> <given-names>Vilmundur</given-names> </name> <name><surname>Rutters</surname> <given-names>Femke</given-names> </name> <name><surname>Beulens</surname> <given-names>Joline W.
