Long-term morbidity rates of contract servicemen Russian Navy (2003–2021)

OBJECTIVE. To study the medical and statistical indicators of military personnel’s morbidity undergoing military service under contract, which will enable to clarify the necessary forces and means of the medical service, and focus on prevention of leading classes of diseases and injuries.

MATERIALS AND METHODS. We studied the morbidity rates of contract servicemen in the reports on the health status of personnel and the activities of the medical service in the form 3/MED of military units in which at least 70 % of the total number of Russian Navy servicemen served. Nosology was aligned with the chapters of the International Classification of Diseases and Related Health Disorders, 10th revision (ICD-10). The morbidity rate was calculated per 1000 servicemen or in ppm (‰), mortality – per 100 thousand people or 10^-5. We calculated the morbidity and its share in the categories of servicemen serving under contract: officers and warrant officers, sailors and petty officers, female servicemen.

RESULTS. The average long-term level of primary morbidity of contract servicemen in the Russian Navy for 19 years (2003– 2021) was 389.4 ‰ with a share of 44.2 % of the structure of the entire cohort morbidity in the Russian Navy, hospitalizations – 228.7 ‰ and 32.1 %, days of work loss – 4734.7 ‰ and 41.2 %, dismissals – 11.81 ‰ and 42.1 %, mortality – 93.74 ×10^–5 and 87.6 %, respectively. The dynamics show a level decrease in almost all accounting types of morbidity in the last observation period, with the exception of a slight increase in the level of primary morbidity. In the Russian Navy contract servicemen, in comparison with the Russian Navy cohort, there is an increase in the proportion of cases for all types of morbidity, with the exception of dismissal, which has decreased in the last observation period. The most pronounced levels of morbidity (except for mortality) were recorded in female servicemen with a low proportion in the structure. There are large unrealized opportunities in the implementation of medical and preventive measures for female servicemen. In the dynamics of the structure for all types of morbidity, an increase in the proportion was revealed among sailors and petty officers, with a decrease in the proportion of other categories of contract servicemen.

CONCLUSION. Focusing on prevention, early detection of diseases in the leading classes, their treatment and rehabilitation can significantly reduce morbidity and improve the health of military personnel. The presented medical and statistical indicators will allow calculating the forces and resources for planning the organization of medical support for military personnel serving under contract in the Russian Navy.
