Comparison of occupational diseases development during one decade in the Slovak and Czech Republic

Objectives: An occupational disease (OD) is a disorder or health condition which arises due to work related activities and tasks or is caused by work environment. The impact of ODs on medical and social system may be considered as a very important in relation to mortality, morbidity, and invalidity. The most common ODs in the European Union are musculoskeletal disorders (58% of all ODs in 2015). The aim of the study was to determine the differences in the incidence of occupational diseases between the Slovak Republic (SK) and the Czech Republic (CZ).

Methods: Data were obtained from the Health Statistics Yearbooks of the National Health Information Centre of the Slovak Republic and in CZ from the Institute of Health Information and Statistics of the Czech Republic. We worked with records from 2009 to 2019. The average incidence rates (aIR) per 100,000 labourers were calculated based on the number of workers in a given year. All data were calculated separately for SK and CZ, and for males and females. P < 0.05 was considered a significant value.

Results: In SK, the number of ODs diagnosed from 2009 to 2019 amounted to 2,351 cases in males and 1,605 cases in females. In CZ, the amount of ODs diagnosed from 2009 to 2019 reached 6,616 cases in males and 5,513 cases in females. In SK, from 2009 to 2019, the incidence of ODs decreased significantly from 7.3 to 4.8 cases per 100,000 labourers (rs = -0.76; p = 0.006). Diseases from one-sided excessive load were the most common ODs in SK (aIR = 7.6 ± 2.2) and in CZ (aIR = 8.2 ± 3.5), followed by ODs caused by vibration. Occupational diseases due to noise, vibrations and SiO₂ inhalation were considerably more common among males. Diseases due to long-term excessive one-sided load, skin and infectious diseases were more prevalent in females. Occupational hearing damage due to noise was more frequent in SK and silicosis, asthma bronchiale, respiratory allergies, dermatoses, and infectious diseases were remarkably more frequent in CZ.

Conclusion: Regarding the main goal, we found a significantly higher aIR of ODs caused by noise in SK than in CZ. In CZ, there was a markedly higher presence of ODs caused by SiO₂ inhalation, asthma and respiratory allergy, ODs of skin and infectious and parasitic ODs when compared to SK. In both countries different principles for discontinuance in work are applied when a risk factor occurs. It is necessary to enhance surveillance data and reporting of ODs and increase investments in occupational safety, health education and research for the future.
