D.adtrubetskov@gmail.comZhyrovK. S.-Saratov Medical Scientific Center of Hygiene of the Federal budget institution of science «Federal Scientific Center of Medical and Preventive Technologies of Public Health Risk Management»1512202129225425901062021Copyright © 2021,2021The article considers “the effect of healthy worker” as a source of systematic errors that makes epidemiological studies in occupational medicine less reliable and this is a significant problem. It is very important to analyze the professions and work conditions under which the phenomenon of self-selection and artificial «health improvement» of working population is to be expected.The scientific publications from open databases and other sources, discussing effect of self-selection under various work conditions and in various professions were analyzed. The data related to effect of healthy worker during labor activity in conditions of contact with industrial dust, allergens, radiation, physical load is discussed. In development of self-selection, psycho-emotional intense work is of greatest importance. In many specialties, this effect plays an essential role in the formation of rate of arterial hypertension. The substantial staff turnover and self-selection are associated with shift and night work, disorders of sleep-wake rhythm in various specialties.The underestimation of the effect of healthy worker may result in underestimation of the degree of harmfulness of work. On the contrary, its analysis will permit to obtain more accurate data on the impact of occupational work conditions on human organism and to develop methods of professional selection and recommendations on diseases prevention.healthy worker effectself-selectionoccupational medicinereviewэффект здорового рабочегосамоотбормедицина трудаобзор1.Максимов С.
