An observational non-interventional cross-sectional, cohort, prospective phase IV clinical study included office workers (151 people, age 18–44 years), who were prescribed an aqueous solution of vitamin D. The concentration of 25(OH)D in the blood of patients was measured before and after undergoing treatment. The duration of therapy, depending on the degree of deficiency, was 4 or 8 weeks. The SF-36 scale was used to assess the physiological and psychological status.</p></sec><sec><title>Results</title><p>Results. In 75.5% of the study participants, a insufficiency or deficiency of vitamin D was detected. Differences in the average content of 25(OH)D in blood serum before and after treatment with vitamin D were statistically significant. The level of vitamin D in blood serum, measured by the content of its metabolite 25(OH)D &lt;30 ng/ml, is regarded as suboptimal, i.e. its insufficiency occurs, and &lt;20 ng/ml – as vitamin D deficiency (p&lt;0.0001). The SF-36 score showed significant statistically significant improvements in overall health, physical functioning, and pain in individuals with vitamin D deficiency after vitamin D supplementation. The use of multiple linear regression demonstrated an association of serum 25(OH)D levels with vitamin D-rich foods taken less than once a week.</p></sec><sec><title>Conclusions</title><p>Conclusions. Vitamin D deficiency is very common among office workers: 75.5% had D 25(OH)D levels below 30 ng/ml. Vitamin D deficiency is corrected by taking this vitamin. Vitamin D supplementation helps to improve physical and mental health indicators. Serum 25(ОН)D levels are associated with intake of vitamin D-rich foods and duration of vitamin D treatment.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: изучение распространенности дефицита витамина D и анализ результатов терапии у офисных работников, включая оценку качества жизни.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В наблюдательное неинтервенционное кросс-секционное когортное проспективное клиническое исследование IV фазы вошли офисные работники (151 человек, возраст 18–44 года), которым был назначен водный раствор витамина D. Концентрация 25(ОН)D в крови пациентов была измерена до и после прохождения лечения. Продолжительность терапии в зависимости от степени дефицита составила 4 или 8 нед. Для оценки физиологического и психологического статуса использовали шкалу SF-36.</p></sec><sec><title>Результаты</title><p>Результаты. У 75,5% участников исследования была выявлена недостаточность или дефицит витамина D. Различия в среднем содержании 25(ОН)D в сыворотке крови до лечения витамином D и после него были статистически достоверны. Уровень витамина D в сыворотке крови, измеряемый по содержанию его метаболита 25(OH)D, меньше 30 нг/мл расценивался как субоптимальный, т.е. имела место его недостаточность, а меньше 20 нг/мл – как дефицит витамина D (p&lt;0,0001). Оценка по шкале SF-36 показала значительное статистически достоверное улучшение параметров общего здоровья, физического функционирования и болевых ощущений у лиц с дефицитом витамина D после его восполнения. Применение множественной линейной регрессии продемонстрировало ассоциацию уровня 25(ОН)D в сыворотке крови с приемом продуктов, богатых витамином D, реже 1 раза в неделю.</p></sec><sec><title>Заключение</title><p>Заключение. Недостаточность витамина D весьма распространена среди офисных работников: у 75,5% уровень 25(ОН)D был ниже 30 нг/мл. Недостаточность витамина D корригируется за счет приема данного витамина, который способствует улучшению показателей физического и ментального здоровья. Уровень 25(ОН)D в сыворотке крови ассоциирован с приемом богатых витамином D продуктов и длительностью лечения витамином D.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Витамин D</kwd><kwd>холекальциферол</kwd><kwd>дефицит 25(OH)D</kwd><kwd>SF-36</kwd><kwd>показатели физического и ментального здоровья</kwd><kwd>офисные работники</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Vitamin D</kwd><kwd>cholecalciferol</kwd><kwd>25(OH)D deficiency</kwd><kwd>SF-36</kwd><kwd>physical and mental health indicators</kwd><kwd>office workers</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Holick M.F.
