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

Next Steps in Use of the Eating Disorder Examination and Related Eating Disorder Assessments: A Call for Consensus

OBJECTIVE

Since its publication almost 35 years ago, the Eating Disorder Examination (EDE) and its companion paper-and-pencil self-report-the Eating Disorder Examination-Questionnaire (EDE-Q)-have remained some of the most widely used and studied tools for the assessment of eating disorder symptoms. Widespread use of the EDE has persisted despite notable limitations of the measure, while other assessment tools developed in the decades since have been inconsistently adopted, both of which may have consequences for accumulation and replication of knowledge within the field.

METHOD

In the current forum, we propose that common critiques of the EDE are representative of larger issues that face the subfield of ED assessment. Therefore, we propose that larger efforts focused on (a) developing decision-making frameworks for assessment evaluation and selection, (b) alignment in flexibly adapting measurements for use in different contexts, and (c) consensus in reporting on assessment implementation and alteration should be paired with and could effectively inform more pragmatic revision of tools like the EDE.

RESULTS

We outline a range of recommendations through which the field can address issues related to lack of consensus in assessment-related decision-making, inconsistency in measure administration and scoring, and inadequate reporting on assessment practices in peer-reviewed journals.

DISCUSSION

In sum, we propose that undertaking planful research regarding current use of the EDE and facilitating field-wide discussion regarding innovation in measure selection and administration can facilitate needed improvement in assessment rigor, data sharing, and inclusiveness within the field.

The Association Between Disordered Eating and Musculoskeletal Injury Among Marine Officers Upon Entry to the Basic School

INTRODUCTION

Active duty service members (ADSMs) may be at heightened risk for eating disorders (EDs) and sub-clinical disordered eating (DE). ADSMs are also at a high risk for musculoskeletal injury (MSK-I). Given the risk for EDs/DE among ADSMs as well as robust physical requirements of military training, additional research is needed to elucidate links between DE and risk for MSK-I among ADSMs. The aim of the present study was to assess the prevalence of DE and associations with MSK-I among Marine Corps officers entering a 6 month leadership course.

MATERIALS AND METHODS

The current cross-sectional study is part of a large, prospective study, the Initiation of Marine Physiological Assessment of Combat Training (IMPACT) study. Participants completed the Eating Disorder Examination-Questionnaire Short (EDE-QS) and self-reported the presence of a recent (≤6 months) MSK-I upon entry to an officer training course. A logistic regression was used to assess the association between elevated DE (EDE-QS ≥15) and recent MSK-I, adjusting for age, race, sex, and commissioning source.

RESULTS

N = 1,382 officers (11.6% female, MAge: 24.8 ± 2.9 years, 26.6% racial/ethnic minority) completed the questionnaires. Seven percent had elevated DE (EDE-QS score ≥15) (female: 10.6%, male: 6.9%, P = .10); 18.3% self-reported recent MSK-I (female: 26.3%, male: 17.3%; P = .009). Females had 17% greater odds of MSK-I compared to males (aOR: 1.17, 95% CI: 1.03-1.33, P = .02). Moreover, females with elevated DE had greater odds of MSK-I than males with elevated DE (aOR= 1.38); among females, odds of MSK-I were greatest among those with elevated DE (aOR= 1.35).

CONCLUSIONS

In this sample of Marine officers, DE was associated with greater odds of a recent MSK-I among women only. Results align with previously reported relationships between DE and skeletal health in female athletes. Prospective research is needed to elucidate the temporal nature of these relationships.

Examining Longitudinal Relations Between Eating Disorder Symptoms and Negative Emotion Variability in Military Members

Up to a third of service members and Veterans experience disordered eating. Disordered eating can be maintained through negative reinforcement of painful and unpleasant emotions such as guilt, shame, sadness, and hostility. Hostility is a negative emotion that may be particularly relevant for service members and Veterans, yet hostility's relation to disordered eating remains understudied. Further, variability in emotions may be particularly relevant, given that variability in emotions is often a stronger predictor of psychopathology than mean levels. Thus, the goal of the present study was to assess a potential bidirectional relationship between disordered eating symptoms and individuals' variability of hostility, stress, anxiety, sadness, and shame. Participants (N = 94, Mage = 32.2, 75.8% men; 81.8% White) completed 30 days of ecological momentary assessment (EMA) with four assessments per day along with baseline and follow-up measures including the Eating Pathology Symptom Interview (EPSI), which assessed eight disordered eating symptom domains. Hierarchical regressions revealed that higher baseline levels of Binge Eating and Excessive Exercise predicted greater intraindividual hostility variability. Further, more hostility variability predicted higher Cognitive Restraint at 1-month follow-up. Baseline disordered eating symptoms were not associated with intraindividual variability in stress, anxiety, sadness, or shame. However, greater intraindividual variability in shame predicted higher Muscle Building at 1-month follow-up. Hostility variability was the only emotion that was predicted by, and predictive of, disordered eating symptoms. These findings suggest that hostility may be a relevant treatment target for service members with disordered eating.

Stress, hardiness and eating disorder symptoms in military academy cadets

Eating disorders are a persistent and debilitating problem, especially among college age men and women. This problem is exacerbated in occupations such as the military, where maintenance of strict standards regarding weight, fitness and appearance is important for job retention and promotion. Also, previous research confirms that stress is a contributing element to eating disorders. It is thus important to identify factors that may assist individuals to remain resilient and avoid stress-related health and eating difficulties. The present study utilizes historical data to examine the impact of stress on health and eating disorder symptoms in a representative sample of West Point military academy cadets, while testing the role of gender and hardiness as stress moderators in this relation. A survey containing measures of stress, hardiness and eating disorders symptoms was completed by 387 cadets in the fall and spring of 2000-2001. Moderation effects were tested with advanced conditional process analysis procedures developed recently by Hayes (2022). Results show that hardiness was a significant moderator, with cadets low in hardiness showing increased eating disorder symptoms and more general health symptoms. While gender was not a significant moderator with respect to eating disorder symptoms, it was significant for general health symptoms; female cadets showed more stress-related health symptoms than their male counterparts. These results suggest that eating disorder symptoms in military academy cadets and college students more generally may be reduced through programs aimed at developing hardiness attitudes and stress coping approaches.

Posttraumatic Stress Disorder and Weight Loss in Male and Female Active-duty Service Members: A Weight Management Study

BACKGROUND

Overweight and obesity are critical public health concerns with relevance to U.S. military personnel, as active duty service members must meet physical fitness and body composition standards. Biological sex and posttraumatic stress disorder (PTSD) diagnosis may affect service members' weight management efforts, but it is unclear what contribution each of these factors independently or in combination have on weight loss.

METHOD

Addressing this gap in knowledge, the current study used multilevel models to examine the effects of sex and self-reported PTSD diagnosis on change in weight of active duty Navy service members (n = 178, 61% female, 24% PTSD) over the course of and after a behavioral weight management intervention.

RESULTS

On average, participants' weights decreased significantly during the intervention (P < .001), and there was a significant sex-by-PTSD interaction effect such that male participants without a self-reported PTSD diagnosis and female participants with a self-reported PTSD diagnosis lost significantly more weight during the intervention than their counterparts (P = .015). The main effects of sex and self-reported PTSD diagnosis on weight change during the intervention were nonsignificant (P's ≥ .24). While weight remained stable on average during the follow-up period (P = .28), female sex marginally predicted weight loss during the follow-up period (P = .07), whereas self-reported PTSD diagnosis and the sex-by-PTSD interaction were not significant (P's ≥ .16).

CONCLUSIONS

These results highlight the importance of considering both sex and PTSD diagnosis as factors that together may influence the efficacy of behavioral weight management programs for active duty service members.

Eating- and Weight-Related Disorders in the Armed Forces

BACKGROUND/OBJECTIVES

Like in the general population, the prevalences of eating- and weight-related health issues in the armed forces are increasing. Relevant medical conditions include the eating disorders (EDs) anorexia nervosa, bulimia nervosa, binge eating disorder, and avoidant restrictive food intake disorder (ARFID), as well as body dysmorphic disorder, muscle dysmorphia, and the relative energy deficiency in sport (RED-S) syndrome.

METHODS

We performed a narrative literature review on eating- and weight-related disorders in the armed forces.

RESULTS

Entry standards might exclude people with obesity, with EDs, or at high risk for EDs from entering the armed forces for military reasons and to protect the individual's health. Relevant potential risk factors of eating- and weight-related disorders in the military are the emphasis on appearance and fitness in the military, high levels of stress, military sexual trauma, post-traumatic stress disorder, deployment, relocation, long commutes, consumption of ultra-processed foods and beverages, limitations on food selection and physical exercise, and intensive combat training and field exercises. Eating- and weight-related disorders negatively impact professional military appearance and lead to problems with cardiorespiratory and neuromuscular fitness; daytime sleepiness; and a higher risk of musculoskeletal injuries, and other physical and mental health problems. Current and potential future therapeutic options include occupational health measures, psychosocial therapies, neuromodulation, and drug treatments.

CONCLUSIONS

Even though randomized controlled trials (RCTs) have been performed to test treatments for obesity in the armed forces, RCTs for the treatment of EDs, body dysmorphic disorder, muscle dysmorphia, and RED-S syndrome are lacking in the military context.

Distinguishing probable atypical anorexia nervosa from weight loss alone in a national sample of U.S. Military Veterans: Disentangling the roles of weight suppression and cognitive concerns

OBJECTIVE

Veterans are at high risk for eating disorders (EDs), and specifically for atypical anorexia nervosa (atypical AN). The current study aimed to better understand this under-studied disorder and how it differs from weight loss without ED cognitive features.

METHOD

Secondary analyses were conducted with data from a national study of Veterans (N = 882, 49.4% women). Participants were categorized into four mutually exclusive groups using the Eating Disorder Diagnostic Scale 5: probable atypical AN, a cognitive concerns group (Cog Only), a weight suppressed group (WS Only), and a no ED control group. Adjusted regression models were used to compare groups on measures of eating pathology and mental health. Three weight suppression thresholds (5%, 10%, and 15%) for probable atypical AN were also tested.

RESULTS

The sample was comprised of 12% probable atypical AN, 23.6% Cog Only, 16.3% WS Only, and 48.1% Control. The probable atypical AN group was most like the Cog Only group except for higher levels of dietary restraint. Atypical AN fared worse and was least like the Control group followed by the WS Only group. All weight suppression thresholds significantly predicted dietary restraint, with 5% being the best predictor.

DISCUSSION

Results found that probable atypical AN is a distinct clinical entity and that the exact weight suppression threshold associated with atypical AN is less important than having any weight suppression. Findings highlight the clinical significance of atypical AN and the importance of gaining a better understanding of how to address this clinical entity.

PUBLIC SIGNIFICANCE

Atypical anorexia nervosa is a relatively underexamined but highly prevalent eating disorder in the Veteran population. Results show that ED cognitive features are more closely linked to clinically significant eating pathology and poor mental health than weight suppression alone suggesting that negative thinking about weight gain and appearance, regardless of the presence or severity of weight loss, may signal the need for specialized intervention.

The Risk of Orthorexia and the Prevalence of Emotional Eating Behaviours among Polish Military Flying Personnel in Relation to Body Mass Index (BMI) and Sociodemographic Factors

BACKGROUND

Proper nutrition has a positive impact on health. Paradoxically, excessive preoccupation with healthy eating may lead to the emergence of abnormal eating behaviours and increase the risk of developing disorders. The aim of this study was to assess the risk of orthorexia (ON) and the prevalence of emotional eating (EE) in military flying personnel of the Polish Air Force in relation to BMI and sociodemographic factors.

METHODS

This study included 760 soldiers (including 60 females) taking part in the National Health Programme 2021-2025. The ORTO-15 questionnaire and EEQ were used to assess the risk of ON and EE.

RESULTS

The risk of ON occurred in 28.9% of military flying personnel and was significantly more frequent in soldiers with a normal weight (46.4%), under 40 years of age (42.7%), and with higher education (42.7%). The prevalence of EE was found in approximately 12.3% of the respondents and was significantly more common in soldiers with diagnosed obesity (17.5%), women (21.7%), and soldiers with higher education (13.6). Other sociodemographic variables did not differentiate the results of the ORTO-15 questionnaire and EEQ.

CONCLUSIONS

The obtained results indicate that the problem of eating disorders also occurs in military populations. The necessity of continuing research in this area is discussed.

Association between body composition standards and eating disorder medical claims among active-duty service women

INTRODUCTION

Eating disorders are a worldwide public health concern with the United States having a particularly high prevalence. Eating disorders are of particular concern to the Department of Defense and Military Health System (MHS) because body composition standards are in place for active-duty service members.

METHODS

We conducted a cross-sectional study of active-duty service women (ADSW) ages 18 and older in the U.S. Army, Air Force, Navy, and Marine Corps during fiscal years (FY) 2018-2019. Utilizing claims data from the MHS Data Repository (MDR), we identified ADSW with a Body Mass Index (BMI) measure during the study period and compared their BMI to Service-specific requirements and diagnosis of an eating disorder.

RESULTS

We identified a total of 161,209 ADSW from the MDR in FYs 2018-2019 with a recorded BMI, of whom 61,711 (38.3%) had a BMI exceeding the maximum BMI Service-specific standards during the study period and 0.5% had an eating disorder diagnosis. Increased risk of an eating disorder was found in ADSW with an Underweight BMI. Further, we found that there was no association of disordered eating diagnoses among ADSW who were near the maximum height/weight standard set by their Service.

CONCLUSION

There appears to be no association between body composition standards of the Services and eating disorder diagnoses in ADSW. We were not able to investigate unhealthy habits around diet or exercise directly related to body composition standards.
