This article presents the results of the study of the structure and dynamics of mental and behavio ral disorders among the soldiers of the National Guard of Ukraine (NGU) who undergo a stationary survey at the Communal Institution "Dnipropetrovs’k Clinical Psychiatric Hospital" of the Dnipropetrovs’k Regional Council in 2014—2017. The characteristics of the studied servicemen (201 persons) by age, years of recruitment and the type of staffi ng of units were presented. All surveyed military personnel of NGU registered mental and behavioral disorders. In the overall structure of the revealed mental illness in the NGU military personnel for 2014— 2017, neurotic stress-related and somatoform disorders (35.3 %), personality disorders and behavior (27.0 %), and psychological and behavioral disorders as a result of psychoactive abuse substances (17.4 %) prevailed. In military service mental and behavioral disorders were signifi cantly more frequent than those who contracted or partially mobilized, which may be due to low motivation for service. For 2014—2017 years, the growth of neurotic, stressrelated and somatoform disorders, schizophrenia, schizotypic, delusional disorders and mental retardation was observed in NGU's military personnel. It was concluded that the received data on the structure and dynamics of mental and behavioral disorders in the NGU military personnel should be taken into account at the development of psychoprophylaxis and treatment and rehabilitation measures for this contingent of persons.
