OBJECTIVE: The article deals with occupational health protection and identification of health risks in the work environment of the Ministry of Defence (MoD) of the Czech Republic (CR). It focuses on the assessment of the incidence of occupational diseases (OD) in high-risk and risk-free occupational categories in the years 2010-2019 and compares them with data from the civilian sector. It identifies the differences between military staff and civilian employees of the MoD. METHODS: From the records of OD at the Department of Occupational Diseases of the Central Military Hospital in Prague, the data on acknowledged OD from the years 2010 to 2019 were obtained and then a retrospective analysis focusing on the classification of work at risk was performed. The obtained data were compared with the data from the Czech National Registry of Occupational Diseases (NROD), which are published annually by the National Institute of Public Health. RESULTS: In the years under review, 191 OD were confirmed at the area of MoD, 26% of all OD occurred in employees classified in the occupational risk category. Compared with the data in the NROD, where 50% of OD were found to have been caused by high-risk work, the incidence of OD caused by high-risk work in professional soldiers is lower. Only 1.6% of all OD occurred in professional soldiers whose work was classified as high-risk one. In civilian employees of MoD 24.6% of all OD were connected with high-risk work. On the contrary, the proportion of OD occurring in professional soldiers working in risk-free categories was 57.6%, in civilian employees of MoD was the ratio much lower - 16.2%. CONCLUSION: Work at the Ministry of Defence was not adequately categorized, therefore, in 2020 a new categorization of work was introduced, which together with preventive measures could contribute to reducing the incidence of OD at the Ministry of Defence.
