Типология циркадных (суточных) ритмов человека активно изучается в медицине труда с точки зрения возможностей адаптации к разным условиям работы, в том числе со сменным графиком. В последние годы описан бимодальный хронотип (БХ), который характеризуется одновременным присутствием признаков экстремально утреннего и экстремально вечернего типов без доминирования какого-либо из них. У работающих с ночными сменами БХ не изучен.</p><p>Цель работы — оценка выявляемости БХ у работающих с ночными сменами в сравнении с дневным графиком работы.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Определение хронотипа (ХТ) проведено у 95 работников, разбитых на две группы: 1-я — 55 работающих с ночными сменами, 2-я — 40 работающих только по дневному графику. Для определения БХ использовался алгоритм на основе опросника Morningness Eveningness Questionnaire (MEQ) по B.J. Martynhak и соавторам.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлено, что 7,3% работающих с ночными сменами и 5,0% с дневным графиком работы имеют БХ. Пере-классификация ХТ приводит к уменьшению доли работников с промежуточным ХТ, в то время как представленность утреннего и вечернего ХТ не изменяется. Возможность наличия БХ нужно учитывать при обследованиях работающих, проводимых для формирования программ здоровья с учетом особенностей хронотип-ассоциированной патологии, а также для повышения работоспособности за счет рациональной организации рабочего времени.</p></sec><sec><title>Выводы</title><p>Выводы: Определение индивидуального ХТ является серьезной составляющей при формировании программ здоровья у лиц трудоспособного возраста. Знание ХТ позволяет минимизировать вероятность снижения и потери работоспособности за счет рациональной организации рабочего времени и профилактических программ, нацеленных на определенные хронотип-ассоциированные нарушения здоровья.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Typology of diurnal (circadian) human rhythms is actively studied in occupational medicine, from the viewpoint of adaptation to various work conditions including those with shift working schedule. In recent years, evidences outline bimodal chronotype characterized by simultaneously present signs of extreme morning and extreme evening types without dominating one of them. Studies did not cover bimodal chronotype in night-shift workers.</p><p>Objective is to evaluate presence of bimodal chronotype in night-shift workers if compared to day-shift schedule.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Chronotype outlining covered 95 workers divided into 2 groups: first — 55 night-shift workers, second — 40 workers on day schedule. Bimodal chronotype was diagnosed via algorithm based on questionnaire Morningness Eveningness Questionnaire (MEQ) by B.J. Martynhak et al.</p></sec><sec><title>Results</title><p>Results. Findings are that 7.3% of night-shift workers and 5.0% of workers with day schedule demonstrate bimodal chronotype. Changed chronotype classification leads to smaller share of workers with intermediate chronotype, but quota of morning and evening chronotypes does not change. Possibility of bimodal chronotype should be respected in examination of workers for designing health programs with consideration of chronotype-associated diseases and for better performance due to rational management of working time.</p></sec><sec><title>Conclusions</title><p>Conclusions. Diagnosis of individual chronotype is a serious part in health programs formation in able-bodied population. Chronotype knowledge helps to minimize possible decrease and losses of performance due to rational working time management and preventive programs aimed to diagnose chronotype-associated health disorders.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хронотип</kwd><kwd>бимодальность</kwd><kwd>ночные смены</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronotype</kwd><kwd>bimodality</kwd><kwd>night-shift work</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">Цфасман А.З.
