Работа посвящена изучению статуса витамина D у девочек-подростков и подбору адекватных доз для коррекции. Цель работы. Исследовать динамику концентрации кальцидиола в сыворотке крови на фоне приема витамина D3 и оценить эффективность корригирующих доз витамина у девочек-подростков г. Москвы.</p></sec><sec><title>Дизайн исследования</title><p>Дизайн исследования. Двойное слепое плацебо-контролируемое проспективное рандомизированное клиническое исследование.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследовании участвовали девочки-подростки 11-17 лет (n = 218) 1-2-й групп здоровья, у которых произведено определение сывороточного уровня 25(OH)D, после чего участницы рандомизированы случайным образом в основную и контрольную группы. Девочки-подростки основной группы получали витамин D3 в форме таблеток, а контрольной группы - плацебо. Длительность исследования составила 6 мес. Доза витамина D3 зависела от исходного сывороточного уровня кальцидиола и составляла от 800 до 2000 МЕ. После окончания курса приема у девочек, завершивших исследование (n = 192), повторно определен статус витамина D.</p></sec><sec><title>Результаты</title><p>Результаты. Исходно у 96,4% девочек выявлен низкий статус витамина D, при этом наблюдалась недостаточность витамина у 26,6%, дефицит - у 57,8%, глубокий дефицит - у 12%. Медиана уровня 25(OH)D в основной группе до приема витамина составляла 16,25 нг/мл, после приема - 24,1 нг/мл, в контрольной группе - 17,9 и 11,4 нг/мл соответственно (р &lt; 0,001). В основной группе увеличение содержания метаболита наблюдалось у 94,9% обследуемых, исходно выявленный глубокий дефицит полностью отсутствовал.</p></sec><sec><title>Выводы</title><p>Выводы. Дифференцированный подход к назначению различных доз холекальциферола, в зависимости от исходного уровня 25(OH)D, ИМТ и возраста, является эффективным методом восполнения дефицита витамина D в организме подростков. Высокая вероятность нормализации статуса витамина D в отдельных возрастных группах, в основном при назначении невысоких корригирующих доз холекальциферола, обосновывает возможность их применения в течение 6 мес. и более у подростков в период пубертата.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The work is devoted to the study of vitamin D status in adolescent girls and the selection of adequate doses for its correction.</p></sec><sec><title>Study objective</title><p>Study objective. To study the dynamics of calcidiol concentration in the blood serum against vitamin D3 intake and evaluate the effectiveness of correcting doses of vitamin in adolescent girls from Moscow.</p></sec><sec><title>Study design</title><p>Study design. A double-blind, placebo-controlled, prospective, randomized clinical study.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study involved adolescent girls aged from 11 to 17 years (n = 218) from I-II health groups, with determined serum level of 25(OH)D. Participants were randomly assigned to the main and control groups. The adolescent girls in the study group received vitamin D3 tablets, and the control group received a placebo. Study duration was 6 months. The dose of vitamin D3 was dependent on baseline serum caLcidioL levels and ranged from 800 IU to 2000 IU. Vitamin D status was redetermined in the girls who completed the treatment (n = 192).</p></sec><sec><title>Results</title><p>Results. Initially, 96.4% of girls had a low vitamin D status, while vitamin D insufficiency was observed in 26.6%, deficiency in 57.8%, deep deficiency in 12%. The median level of 25(OH)D in the main group before taking the vitamin was 16.25 ng/ml, after taking - 24.1            ng/ml, in the control group - 17.9 and 11.4 ng/ml, respectively (p &lt; 0.001). In the main group, an increase in the content of the metabolite was observed in 94.9% of the subjects, the initially identified pronounced deficit was completely absent.</p></sec><sec><title>Conclusions</title><p>Conclusions. A differentiated approach to prescribing different doses of cholecalciferon, depending on the baseline level of 25(OH)D, BMI and age, is an effective method for replenishing vitamin D deficiency in adolescents. The high probability of normalization of vitamin D status in certain age groups, mainly with the appointment of low corrective doses of cholecalciferol justifies the possibility of their use for 6 months or more in adolescents during puberty period.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>витамин D</kwd><kwd>кальцидиол</kwd><kwd>25(OH)D</kwd><kwd>недостаточность</kwd><kwd>глубокий дефицит</kwd><kwd>коррекция</kwd><kwd>эффективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vitamin D</kwd><kwd>calcidiol</kwd><kwd>25(OH)D</kwd><kwd>insufficiency</kwd><kwd>deep deficiency</kwd><kwd>correction</kwd><kwd>effectiveness</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">CedieL G., Pacheco-Acosta J., CastiUo-Duran C.
