Eating Disorders in U.S. Active Duty Military Members and Veterans: A Systematic Review

Abstract

Introduction: Feeding and eating disorders can be difficult to treat and frequently co-occur with other mental health conditions. The last systematic review of eating disorders in a military and veteran population was published in 2015. An updated review is warranted to re-examine the current literature on eating disorders in the active duty and veteran populations.

Materials and methods: A systematic review that described the prevalence, co-occurrence of other disorders and/or events, and health care utilization of U.S. active duty members and veterans was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Databases and Medical Subject Headings (MeSH) terms used are listed in Appendix A. Each category of the literature was extracted and graded using the Oxford Centre for Evidence-Based Medicine Levels of Evidence.

Results: Twenty-one studies revealed prevalence estimates with varying rates based on demographic information. Trauma exposure is consistently associated with eating disorder development. Individuals diagnosed with eating disorders had greater health care utilization.

Conclusions: Research on eating disorders in the military and veteran populations has expanded in recent years. Limitations of the evidence included in this review stem from the use of self-reported questionnaires, changes to medical record systems, and limited generalizability to the overall population of patients with eating disorders. Further research should investigate the impact of demographic factors and trauma exposure on the development of an eating disorder within the military and veteran populations.
