Разработчики систем управления риском утомления на рабочих местах отмечают, что не существует универсального определения и согласованного способа измерения рабочей нагрузки, и что взаимосвязь между рабочей нагрузкой и усталостью изучена недостаточно.</p><p>Цель исследования — анализ влияния рабочей нагрузки, оцениваемой по продолжительности состояния производственно обусловленной усталости работников, на их субъективное здоровье и риск хронических заболеваний.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследовании принимали участие работники трёх сфер занятости: здравоохранение (697 работников), промышленность (751), образование (687). Определялись 4 показателя риска нарушения субъективного здоровья работников в течение года: наличие синдрома хронического утомления (Рсху), ухудшения здоровья работника в течение года (Руз), длительные болезни в течение года (Рдб), кумуляции усталости в течение года (Рку). Анализировались заболевания, выявленные при периодическом медицинском осмотре. Рассчитывался показатель ЧУнед — продолжительность состояния усталости — «часов усталости за рабочую неделю»: ЧУнед (час) = ПРН (час) × Ксу × Кчу, где: ПРН (час) — фактическая продолжительность рабочей недели; Ксу и Кчу — коэффициенты, учитывающие степень и частоту усталости. Рассчитывался относительный риск (RR).</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что при ЧУнед более 25 часов в неделю в 108 выборочных группах работников в 25 случаях RR превышал контрольный уровень более, чем в 5 раз; в 44 группах сравнения в 2,1–5 раз и в 35-х группах в 1,1–2,0 раза. При ЧУнед более 25 часов наблюдается годовая кумуляции утомления (Рку), схожая у работников всех сфер занятости. При ЧУнед&gt;15 час RR хронических заболеваний костно-мышечной, дыхательной, нервной систем и кожи был в диапазоне 1,31–1,83. RR заболеваний мочеполовой системы (женщины) и эндокринной системы возрастал в 1,13 раза; заболеваний гипертонией, болезней органов пищеварения, зрительной системы RR÷1,05–1,07.</p></sec><sec><title>Заключение</title><p>Заключение. Показатель ЧУнед является физиологическим эквивалентом профессиональной нагрузки работников различных сфер занятости. При ЧУнед&gt;/25 часов наблюдается резкое увеличение рисков здоровью.</p></sec><sec><title>Участие авторов</title><p>Участие авторов:Сорокин Г.А. — концепция и дизайн исследования, ответственность за целостность всех частей статьи, сбор данных литературы, статистическая обработка, написание текста;Чистяков Н.Д. — сбор материалов наблюдений.</p></sec><sec><title>Финансирование</title><p>Финансирование.

The developers of fatigue risk management systems in the workplace note that there is no universal definition and a consistent way to measure workload, and that scientists have not sufficiently studied the relationship between workload and fatigue.</p><p>The study aims to analyze the impact of the workload, estimated by the duration of the state of production-related fatigue of workers, on their subjective health and the risk of chronic diseases.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study involved employees in three areas of employment: healthcare (697 employees), industry (751), education (687). Experts have determined four indicators of the risk of violation of the subjective health of employees during the year: the presence of chronic fatigue syndrome (Rcfs), deterioration of employee health during the year (Rdh), long-term illnesses during the year (Rli), fatigue accumulation during the year (Rfa). We have analyzed the diseases detected during periodic medical examination. The researchers have calculated the HFweek indicator — the duration of the fatigue state — "hours of fatigue per working week": HFweek (hour) = PRN (hour) × Kdf × Kff, where: PRN (hour) is the actual duration of the working week; Kdf and Kff are coefficients that take into account the degree and frequency of fatigue. We also have calculated the relative risk (RR).</p></sec><sec><title>Results</title><p>Results. The researchers have found that with more than 25 hours per week in 108 sample groups of workers in 25 cases, RR exceeded the control level by more than 5 times; in 44 comparison groups by 2.1–5 times and in 35 groups by 1.1–2.0 times. </p><p>With a HFweek of more than 25 hours, there is an annual accumulation of fatigue (Rfa), similar in workers of all spheres of employment. At HFweek&gt;15 hours, the RR of chronic diseases of the musculoskeletal, respiratory, nervous systems and skin was in the range of 1.31–1.83. The RR of diseases of the genitourinary system (women) and endocrine system increased by 1.13 times; diseases of hypertension, diseases of the digestive system, visual system RR÷1,05–1,07.</p></sec><sec><title>Conclusion</title><p>Conclusion. The HFweek indicator is the physiological equivalent of the professional workload of employees in various fields of employment. With HFweek&gt;25 hours, there is a sharp increase in health risks.</p></sec><sec><title>Contribution</title><p>Contribution:Sorokin G.A. — concept and design of the study, responsibility for the integrity of all parts of the article, collection of literature data, statistical processing, writing the text;Chistyakov N.D. — collection of observation materials.</p></sec><sec><title>Funding</title><p>Funding.
