The incidence of military servicemen under contract in the rank of rank-and-file sergeant for 10 years (2007-2016) was studied by analyzing 60% of the annual reports on the health status of personnel and medical service activities in the form 3/MED military of randomly selected units. The average annual incidence rate was 982±33‰, the primary level was 483±13, the need for dispensary observation was 72±5, the total hospitalization was 239±8, the days of work loss were 3913±115, the dismissal for health reasons was 4.1±0.5‰, mortality - 102.7±8.1 per 100 thousand military personnel under the contract. An increase in the rates of general and primary morbidity and a decrease in the rest have been established. Compared to officers, the contracted servicemen had significantly lower levels of overall morbidity, need for dispensary dynamic follow-up, labor losses and layoffs, higher hospitalizations, almost identical - primary morbidity and mortality. The pathology XIX (trauma, poisoning and some other consequences of external causes), X (diseases of the respiratory system), IX (diseases of the circulatory system), XIII (diseases of the musculoskeletal system and connective tissue), XI (diseases of the digestive system), XII (diseases of the skin and subcutaneous tissue) and V (mental and behavioral disorders) classes.
