The article is devoted to the approbation of the modification of the method of the presentation of indices of medical and social losses of the population on an example of environmentally unfavorable Aral Sea region in Kazakhstan. The first step in improvement of the system ofpublic health care is the identification of the most important problems related with the assessment of the disease burden and the adjustment of data of such type in accordance national aims on the decline of medical and social losses in this problem area. So far according to the criteria for the determination of the boundary of ecological catastrophe area one of the indices is the steady gain in the mortality rate. Using the index “Years of Life Lost” (YLL) in medical statistics as a relatively new approach that continues to be improved and its development supposes the improvement in the quality of health statistics. We modified this method consisting in the determination of the coefficient of loss of years. In the given work after comprehensive analysis of the loss of years due to morbidity and mortality on the base of life tables the potential of lost years for the population was determined with bearing in mind of module tables and compared with the loss in years due to the health loss. So far there was declined the dimension of the comprehensive index, there was elevated its comparability with other indices, and the data interpretation has been optimized. Suggested modification can be used for a comprehensive assessment of health state in the execution of epidemiological studies and monitoring of medical and social situation in ecologically unfavorable regions.

Summary: The working conditions of medical staff in the offices of magnetic resonance imaging (MRI) are associated with high levels of stationary magnetic fields (SMF) and electromagnetic fields (EMF) of various frequencies and increased work intensity. It can affect cognitive, psychological and hemodynamic changes of the body with health disorders. It requires not only high professional training, but also compliance with safety measures, as well as monitoring of working conditions, health status and carrying out of medical and preventive measures.

Our research project was aimed at studying the effects of an electromagnetic field of industrial frequency (EMF-IF) on employees of an energy company in Kazakhstan. Material and Methods — The object of our study was the health status of electricians (morbidity with temporary disability – MTD), engaged in the maintenance of power lines, relay protection systems and substations (220 and 500 kV) at an energy enterprise in Kazakhstan. The interrelation and dependence of the intensive MTD indicators on the hygienic factors at the workplace were determined, and the risks were calculated from the obtained data. Results — Unfavorable workplace conditions caused an increase in disorders of the musculoskeletal system (up to 77%), blood circulation (up to 65%), nervous system (up to 52%), skin diseases (up to 46.4%), as well as the manifold rise of the likelihood of neoplasm growth and respiratory diseases. For electricians, the relationships between the nervous system disorders (r=0.792), the circulatory system diseases (r=0.573), the musculoskeletal system ailments (r=0.672) and the EMF-IF parameters were discovered. At the same time, the dependence of the incidence rates of various diseases in workers on EMF, as well as moderate to high computed relative risks, implied the occupational genesis of worklace ailments: for nervous system – R2=0.628, cardiovascular system – R2=0.709, skin – R2=0.729, and musculoskeletal system – R2=0.413. Conclusion — As preventive measures for electricians, we recommended to wear individual exposure meters, to limit work in contact with EMF, to include an oncologist in the medical commission, and for trainees, to screen for oxidative stress proteins and chaperone proteins to exclude a predisposition to oncogenesis.

The state of health of healthcare practitioners with occupational exposure to a complex of hazards may differ from the state of health of general population and justify the need to develop a number of preventive measures for healthcare practitioners. The purpose of the study was assessment of the prevalence of morbidity among medical specialists (MRI and ultrasound diagnostics). Design: retrospective (2018-2021), nonrandomized. Participants: MRI and ultrasound diagnostics specialists, ophthalmologists (as control). An analysis of data on healthcare practitioners seeking for medical care was done (diagnosis by ICD-10). Morbidity was also compared with general population of the RK. Higher morbidity of healthcare practitioners of the listed above specialties with genitourinary and musculoskeletal systems diseases, eye diseases and oncopathology was revealed. Comparing with ophthalmologists, ultrasound diagnostic specialists had higher morbidity with malignant and benign neoplasms (RR 2.74 and RR 9.58, respectively), MRI specialists had higher morbidity with malignant neoplasms and blood diseases (RR 4.73 and RR 1.89, respectively). The incidence rates of SARS-COV-2 in MRI and ultrasound diagnostic specialists and ophthalmologists exceeded those in the general population of the RK. Identified features of the morbidity of healthcare practitioners should be taken into account in labor ergonomics and organization of preventive and screening measures for diagnosing diseases.

The analysis of the loss of years by YLL (Years of Life Lost) from the mortality of the population in the age and sex aspect of nosology class of diseases of the circulatory system in industrial regions of East Kazakhstan and Karaganda regions of the Republic of Kazakhstan (RK). In the dynamics for 2011–2014, a decrease in mortality was established, which is associated with an increase in the quality of medical care.
