Eating Disorders in Military and Veteran Men and Women: A Systematic Review
Abstract: Objective: Eating disorders (EDs) have serious consequences for psychological and physical health. They have high mortality rates and are among the most costly disorders to treat. However, EDs remain understudied in military and veteran populations. The aim of this review was to examine prevalence estimates and associated symptomatology of EDs among military and veteran men and women and to identify factors that may put these individuals at risk for the development of an ED for the purposes of improving detection, intervention, and treatment. Method: A thorough literature review was conducted using the databases PsycINFO and PubMed. All articles with a focus on EDs in military/veteran samples were considered. Results: Studies reveal high prevalence estimates of EDs among military/veteran men and women. Unique features of military life may increase the risk for development of an ED, including: military sexual trauma, strict weight and physical fitness requirements, and combat exposure. A history of trauma was common in individuals diagnosed with an ED in military and veteran samples. Discussion: The high rates of EDs among military and veteran samples underscore the importance of further research, as well as the importance of screening and intervention efforts, in these understudied populations.
Abstract: Disordered eating is a prevalent and relevant health concern that remains understudied among U.S. military veterans. Avoidant/restrictive food intake disorder (ARFID) is a newly recognized feeding and eating disorder characterized by overly restrictive eating due to (a) picky eating, (b) lack of appetite, and (c) fear of aversive consequences related to eating. The Nine-Item ARFID Screen (NIAS) is a recently developed ARFID screening tool with initial validation studies demonstrating psychometric support. However, the psychometric properties of the NIAS have not been investigated in a veteran sample. To advance our understanding of ARFID screening tools that may be appropriate for use in veterans, the present study examined the factor structure of the NIAS using survey data from a large national sample of recently separated veterans (N = 1,486). Measurement invariance across key subgroups was tested in addition to exploring differential associations between the NIAS and related constructs. Results suggested that a three-factor model provided an excellent fit of the data and demonstrated scalar invariance across self-identified men and women, race and ethnicity, and sexual and gender minority (SGM) identity. Some subgroups had higher latent means on the picky eating (women, SGM, non-Hispanic Black), appetite (women, SGM), and fear (women) factors. The NIAS had some overlap with another measure of disordered eating and was moderately correlated with psychosocial impairment and mental health. Overall, the NIAS may be a useful screening tool for ARFID in veterans, given support for the three proposed subscales and equivalence across diverse identities.
