Type 1 schools were not involved in the program of school nutrition improvement, whereas type 2 schools took part in the WFP UN program on the supply of fortified products, as well as the governmental program on improvement of infrastructure and provision of hot meals. </italic></p><p><italic><bold>Results and discussion.</bold> Iron, iodine, and zinc content in fortified wheat flour supplied by WFP UN exceeded the respective values of the local product by a factor of 2.3, 14, and 4.7. Iodized salt (WFP UN) was characterized by an 11-fold increase in iodine content as compared to the locally used salt. The use of fortified wheat flour and iodized salt in type 2 schools for the preparation of school dinners should provide an increased dietary intake of iron, iodine, and zinc by a factor of 2.5, 12, and 4, when compared to type 1 schools, respectively. </italic></p><p><italic><bold>Conclusion.</bold> Therefore, WFP UN along with governmental efforts aimed at improvement of school meals provided from 50% to 100% of the recommended dietary allowance for iron and zinc, whereas in the case of iodine even exceeded recommended values, being indicative of the efficiency of the efforts. At the same time, such programs should be supported by trace element monitoring in the organism for assessment of both efficiency and safety.</italic></p></abstract><trans-abstract xml:lang="ru"><p><italic><bold>Введение.</bold> Целью исследования явилось определение содержания железа, йода и цинка в рационах обедов школьников Республики Таджикистан, а также влияния включения в рацион продуктов, предоставляемых Всемирной продовольственной программой (ВПП) ООН.</italic></p><p><italic><bold>Материал и методы.</bold> Исследование проведено в 2 типах школ, расположенных в Пенджикентском и Айнинском районах Республики Таджикистан. Школы 1-го типа не участвовали в программах по улучшению школьного питания, тогда как школы 2-го типа участвовали в программе ВПП ООН по предоставлению обогащённых микроэлементами продуктов и в государственной программе по улучшению инфраструктуры и предоставлению горячего питания. Анализ содержания железа, йода и цинка проводили методом масс-спектрометрии с индуктивно-связанной плазмой.</italic></p><p><italic><bold>Результаты.</bold> Содержание железа, йода и цинка в обогащённой микроэлементами пшеничной муке, предоставляемой ВПП ООН, превышало соответствующие значения у пшеничной муки местного производства в 2,3; 14 и 4,7 раза соответственно. Йодированная соль ВПП ООН характеризовалась 11-кратным превышением уровня йода по сравнению с образцами местной соли. Использование обогащённой железом и цинком пшеничной муки, а также йодированной соли в школах 2-го типа приводило к достоверному повышению потребления железа, йода и цинка в 2,5; 12, а также 4 раза относительно показателей школ 1-го типа соответственно.</italic></p><p><italic><bold>Заключение.</bold> Таким образом, программа ВПП ООН наряду с организационными мероприятиями по улучшению школьного питания обеспечивала до 50 и 100% суточной потребности детей в железе и цинке, тогда как в случае йода даже превышала данные нормы, что свидетельствует об эффективности проводимых мероприятий. В то же время осуществление подобных мероприятий должно проводиться под контролем мониторинга уровня микроэлементов в организме как с целью оценки эффективности, так и безопасности программ.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>fortification</kwd><kwd>iron</kwd><kwd>zinc</kwd><kwd>iodine</kwd><kwd>arrangements for feeding</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>обогащение</kwd><kwd>железо</kwd><kwd>цинк</kwd><kwd>йод</kwd><kwd>организация питания</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Oberlis D., Kharland B.F., Skal’nyy A.V.
