This problem is especially relevant in young people, due to the failure to reach peak bone mass, which later determines the bone mineral density.</p> <p><bold>Aims</bold> — to determine the prevalence of deficiency and insufficient supply of 25(OH)D in blood serum in the spring, their impact on the indicators of physical development and bone mineral density among cadets of a military higher educational institutions.</p> <p><bold>Methods.</bold> We examined 198 cadets, studying in the first and fourth years of military higher educational institutions in St. Petersburg at the age of 17–25 years. As part of the study, a study of 25(OH)D in blood serum was performed, bone mineral density, muscle strength, anthropometric data, and body composition were additionally determined. The study was conducted in March–May 2023.</p> <p><bold>Results.</bold> The optimal content of 25(OH)D was found only in 22 (11.1%) cadets, while the most pronounced deficiency was registered in boys of fourth of study. It was established that the 25(OH)D level of first year cadets, who arrived from the southern regions of the Russian Federation (21.6 (18.1; 26.3) ng/ ml), was significantly different from the content of 25(OH)D in cadets who arrived from the middle zone (Me 18.7 (16.4; 21.4) ng/ml) (p = 0.017) and northern regions of the Russian Federation (Me 15.2 (13.6; 19.3) ng/ml) (p = 0.022). A decrease in the Z-criterion ≤ –2.0 SD was noted among cadets, mainly in the first year. It was revealed that muscle and fat mass were higher in fourth year boys, however, their muscle strength was not statistically significantly different from that of first year and muscle strength indicators did not depend on the availability of 25(OH)D. Increasing BMI was associated with higher muscle mass (p = 0.0004) and fat mass (p = 0.0006), with muscle strength (p = 0.026) and physical fitness performance (p = 0.012) among cadets with increasing BMI were significantly better compared to cadets who had an optimal BMI.</p> <p><bold>Conclusions. </bold>The results obtained indicate that cadets of a military higher educational institutions of St. Petersburg experience 25(OH)D deficiency and insufficiency, against the background of increased physical activity and prolonged stay in conditions of reduced insolation. This fact indicates the need to correct vitamin D hypovitaminosis in order to prevent osteopenic syndrome and improve physical performance.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>В условиях пониженной инсоляции, характерной для северных регионов Российской Федерации, проявления низкой обеспеченности витамином D зачастую протекают скрыто и длительно не распознаются. Особенно актуальна данная проблема у лиц молодого возраста в связи с недостижением пиковой костной массы, определяющей в дальнейшем минеральную плотность костной ткани (МПКТ).</p> <p><bold>Цели исследования</bold> — определить распространенность дефицита и недостаточной обеспеченности 25(OH)D в сыворотке крови в весенний период, их влияние на показатели физического развития и МПКТ у курсантов военных высших учебных заведений.</p> <p><bold>Методы.</bold> Обследовано 198 курсантов в возрасте 17–25 лет, проходящих обучение на I и IV курсах военных высших учебных заведений г. Санкт-Петербурга. Проведено исследование 25(OH)D в сыворотке крови, дополнительно определены МПКТ, мышечная сила, антропометрические данные, а также компонентный состав тела. Исследование проведено в марте–мае 2023 г.</p> <p><bold>Результаты.</bold> Оптимальное содержание 25(OH)D выявлено только у 22 (11,1%) курсантов, при этом наиболее выраженный дефицит зарегистрирован у юношей четвертого года обучения. Установлено, что уровень 25(OH)D у курсантов I курса, прибывших из южных регионов России (Ме 21,6 (18,1; 26,3) нг/мл), достоверно отличался от содержания 25(OH)D у курсантов, прибывших из средней полосы (Me 18,7 (16,4; 21,4) нг/мл) (р = 0,017) и северных регионов (Me 15,2 (13,6; 19,3) нг/мл) (р = 0,022). Снижение показателя Z-критерия ≤ –2,0 стандартного отклонения отмечено преимущественно у курсантов I курса. Выявлено, что мышечная и жировая массы были выше у юношей VI курса, однако мышечная сила у них статистически значимо не отличалась от показателя первокурсников и показатели мышечной силы не зависели от обеспеченности 25(OH)D. Повышение индекса массы тела (ИМТ) ассоциировалось с более высокими мышечной (p = 0,0004) и жировой (p = 0,0006) массами, при этом показатели мышечной силы (p = 0,026) и успеваемость по физической подготовке (p = 0,012) у курсантов с повышением ИМТ были достоверно лучше по сравнению с курсантами, имевшими оптимальный ИМТ.</p> <p><bold>Заключение. </bold>Полученные данные свидетельствуют о том, что курсанты военных высших учебных заведений г. Санкт-Петербурга испытывают дефицит и недостаточность 25(OH)D на фоне длительного пребывания в условиях пониженной инсоляции. Данный факт указывает на необходимость коррекции гиповитаминоза витамина D с целью профилактики остеопенического синдрома и повышения физической работоспособности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>25(OH)D</kwd><kwd>bone mineral density</kwd><kwd>body composition</kwd><kwd>cadets</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>25(OH)D</kwd><kwd>минеральная плотность костной ткани</kwd><kwd>компонентный состав тела</kwd><kwd>курсанты</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Amrein K, Scherkl M, Hoffmann M, et al.
