Abstract
Abstract Aims: The present study is a review focused on analyzing the physical, psychological, and demographic factors that lead recruits to be dismissed or to request their dismissal during basic military training periods. Methods: This study is a systematic review of cohort studies. The following databases were searched in June 2019 and updated in July 2020: Embase, LILACS, CINAHL, Cochrane, MEDLINE, SCOPUS, SPORTDiscus, Web of Science, and Science Direct databases. The MeSH descriptors military personnel, risk factors, and discharge were used to elaborate the search equations. Reference lists were explored to find studies that examined the association between physical, psychological, and demographic factors that lead recruits to be discharged. The following data were extracted from the studies: profile of the participants, sample size, type of risk factors, the duration of follow-up, and the results of the statistical analysis carried out in the studies included. The risk of bias was analyzed with the Newcastle-Ottawa Scale for cohort studies. Results: A total of 531 titles were retrieved from the databases, and eight articles met the eligibility criteria. The results showed the factors associated with discharge, in descending order: musculoskeletal injuries and other medical questions, depressive and behavioural disorders, performance in physical fitness tests, and others. Factors such as educational level, alcohol use, history of suicide attempt, and imprisonments were not associated with an increased risk of being discharged. Conclusion: Musculoskeletal injuries, depression, running performance, previous physical exercise practice, and demographic factors were associated with an increased risk of being discharged.
Highlights
Discharge is the term used when referring to training military when a withdrawal is requested by recruits for various reasons, resulting in the military personnel being disconnected from the basic training period before it is completed[1]
Statistics of this recruitment center indicate that during the fiscal year of 1998, 15% of recruits were discharged before the basic period was complete, 18% of trained soldiers left the army before completing six months on active duty, and 36% did not see through the service period in the contracts signed with the Army[2]
Due to the high degree of physical overload and the low level of fitness of the recruits, there is a high incidence of injuries in the initial training, that are associated with an elevated number of recruits who are discharged from military service[3]
Summary
Discharge is the term used when referring to training military when a withdrawal is requested by recruits for various reasons, resulting in the military personnel being disconnected from the basic training period before it is completed[1].Being prematurely discharged from the Army Basic Training of the United States of America (ABT) is a concern, as it generates a loss of resources for the recruits and their training, as well as the reduction of readiness and institutional workforce. Statistics of this recruitment center indicate that during the fiscal year of 1998, 15% of recruits were discharged before the basic period was complete, 18% of trained soldiers left the army before completing six months on active duty, and 36% did not see through the service period in the contracts signed with the Army[2]. The basic training of the United States Marine Corps (USMC) involves physical and varied demanding challenges created to train the recruits to successfully develop activities useful for military service. Due to the high degree of physical overload and the low level of fitness of the recruits, there is a high incidence of injuries in the initial training, that are associated with an elevated number of recruits who are discharged from military service[3]
