Рекуррентные респираторные инфекции в детском возрасте являются актуальной медико-социальной проблемой. Питание имеет важное значение для функционирования и развития иммунной системы ребенка.</p></sec><sec><title>Цель</title><p>Цель. Оценить рацион питания и обеспеченность детей с рекуррентными респираторными инфекциями витаминами (А, Е, D, С, В6, В12, фолиевая кислота) и минеральными веществами (Zn, Fe, Mg, Ca, P).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование было включено 65 детей в возрасте от 3 до 8 лет, из них 50 детей с рекуррентными респираторными инфекциями, 15 детей – контрольная группа.</p></sec><sec><title>Результаты</title><p>Результаты. Проведенное исследование среди детей с рекуррентными респираторными инфекциями в возрасте 3–8 лет выявило высокую частоту дефицита витаминов D (69%), А (40%), Е (35%) и минералов Zn (70%) и Fe (44%). Причем наиболее выраженным был дефицит витаминов D, А и Zn у детей основной группы по сравнению с контрольной группой (р &lt; 0,05). По результатам проведенного анкетирования родителей показано, что дети с рекуррентными респираторными инфекциями часто (82%) имеют низкий и избирательный аппетит. При оценке фактического питания в структуре рациона отмечалась низкая частота потребления рыбы, мясных и молочных продуктов, овощей. У большинства детей основной группы имелись нарушения в режиме питания, такие как отсутствие завтрака, избыток углеводов и частое употребление продуктов фастфуда.</p></sec><sec><title>Заключение</title><p>Заключение. Установленные нами особенности рациона питания способны негативно влиять на витаминно-минеральный статус детей с рекуррентными респираторными инфекциями. По итогам исследования уровней витаминов и минералов у детей с рекуррентными респираторными заболеваниями наиболее частые нарушения были установлены для цинка, витаминов D, А и железа.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Recurrent respiratory infections in childhood are a pressing medical and social problem. Nutrition is important for the functioning and development of the child’s immune system.</p></sec><sec><title>Aim</title><p>Aim. To assess the diet and provision of children with recurrent respiratory infections with vitamins (A, E, D, C, B6, B12, folic acid) and minerals (Zn, Fe, Mg, Ca, P).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 65 children aged 3 to 8 years, including 50 children with recurrent respiratory infections, 15 children – the control group.</p></sec><sec><title>Results</title><p>Results. The study among children with recurrent respiratory infections aged 3–8 years revealed a high frequency of deficiency of vitamins D (69%), A (40%), E (35%) and minerals Zn (70%) and Fe (44%). Moreover, the deficiency of vitamins D, A and Zn was most pronounced in children of the main group, compared with the control group (p &lt; 0.05). The results of the survey of parents showed that children with recurrent respiratory infections often (82%) have a low and selective appetite. When assessing the actual nutrition in the structure of the diet, a low frequency of consumption of fish, meat and dairy products, vegetables was noted. Most children of the main group had violations in the diet, such as lack of breakfast, excess carbohydrates and fast food.</p></sec><sec><title>Conclusion</title><p>Conclusion. The dietary features we have established can negatively affect the vitamin and mineral status of children with recurrent respiratory infections. According to the results of the study of the levels of vitamins and minerals in children with recurrent respiratory diseases, the most frequent violations were found for zinc, vitamin D, A and iron.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рецидивирующие респираторные инфекции</kwd><kwd>иммунитет</kwd><kwd>дефицит витаминов</kwd><kwd>дефицит минеральных веществ</kwd><kwd>питание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>recurrent respiratory infections</kwd><kwd>immunity</kwd><kwd>vitamin deficiency</kwd><kwd>mineral deficiency</kwd><kwd>nutrition</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">Chiappini E, Santamaria F, Marseglia GL, Marchisio P, Galli L, Cutrera R et al.
