The Military's Role in the Rising Tide of Eating Disorders
Decision brief
Answer first · skim in under a minute
Military service members and veterans exhibit higher rates of eating disorders compared to the general population, a trend linked to specific psychological and environmental factors within the armed forces. These conditions carry significant mortality risks and have implications for veteran healthcare and disability.
Eating disorders among U.S. service members and veterans are not rare edge cases. Peer-reviewed military cohorts show a measurable clinical burden, with survey screens detecting far more bulimia and binge eating than electronic medical records alone.

Key Takeaways
- A 2024 International Journal of Eating Disorders analysis quantified incidence and prevalence of eating disorders among U.S. military service members for 2016–2021.
- Millennium Cohort data put survey prevalence of bulimia nervosa and binge eating disorder at roughly 0.80%–4.80%, versus about 0.04%–0.14% in medical records.
- Combat deployment, PTSD screens, low social support, and branch of service track with higher disorder risk in longitudinal models.
- Diagnostic gaps mean pharma and VA care planners who rely only on coded diagnoses will undercount need for evidence-based treatments.
How common are eating disorders in U.S. military populations?
Bauman and colleagues reported incidence and prevalence of eating disorders among U.S. military service members for 2016–2021 in the International Journal of Eating Disorders (PubMed 38779988).
That paper sits alongside a broader systematic review of active-duty and veteran literature by Touma and colleagues in Military Medicine, indexed as PubMed 35788384, which found trauma exposure consistently associated with eating disorder development and higher health-care utilization among diagnosed patients.
NIMH’s public overview of eating disorders stresses that anorexia nervosa, bulimia nervosa, and binge eating disorder are serious illnesses with medical complications — framing why underdiagnosis in high-stress occupational groups matters for readiness and long-term care cost.
Why do survey rates exceed medical-record diagnoses?
The Millennium Cohort Study analysis of bulimia nervosa and binge eating disorder followed participants for up to 15 years and compared survey ascertainment with electronic medical records.
According to the American Journal of Epidemiology paper summarized at doi.org/10.1093/aje/kwae204, weighted survey prevalence estimates ranged from 0.80% to 4.80%, while medical-record prevalence was only 0.04% to 0.14%.
That gap implies many service members with probable disorders never receive a coded diagnosis, which shrinks measured prevalence and can delay referral to specialty care.
Which military and psychosocial factors raise risk?
The same Millennium Cohort models linked higher odds of developing bulimia nervosa or binge eating disorder to:
- Active-duty component versus Reserve/Guard
- Army, Marine Corps, or Navy/Coast Guard service versus Air Force
- Combat deployment versus deployment without combat
- Lack of social support, at least one life stressor, PTSD screen positivity, or problem drinking
Touma’s review likewise emphasizes co-occurrence with depression, PTSD, obsessive-compulsive disorder, and substance use disorders — comorbidities that complicate both military retention decisions and civilian veteran care pathways.
What does this mean for pharma and care delivery?
For manufacturers of approved binge-eating pharmacotherapies and developers of anorexia or bulimia candidates, the military and veteran channel is a distinct demand segment with trauma-informed screening needs.
Health systems that only track ICD-coded eating disorders will miss the larger survey-positive population. Screening tools validated in veteran samples, plus integrated PTSD and substance-use pathways, are more aligned with the epidemiologic signal than stand-alone weight-management clinics.
None of the cited papers claim a single causal pathway from body-composition standards to clinical anorexia. Those cultural hypotheses remain discussion points, not measured endpoints in the cohort models above.
What remains unproven?
Published military epidemiology does not yet deliver a definitive, population-wide DSM-5 prevalence that is identical across active duty, Guard/Reserve, and era-specific veteran cohorts.
Claims about exact civilian multiples (for example, “three times the civilian bulimia rate”) should be treated as study-specific comparisons, not universal constants, unless the comparator methodology is stated in the same paper.

Frequently Asked Questions
Are eating disorders more common in the military than in civilians?
Peer-reviewed military cohorts report clinically meaningful eating disorder burden. Survey-based estimates of bulimia nervosa and binge eating disorder are higher than rates captured in medical records, and trauma exposure is repeatedly linked to disorder risk.
What did the Millennium Cohort Study find on bulimia and binge eating?
In a large U.S. military cohort followed up to 15 years, weighted survey prevalence for bulimia nervosa and binge eating disorder ranged from about 0.80% to 4.80%, while medical-record prevalence was far lower at about 0.04% to 0.14%.
Which military factors raise eating disorder risk?
Published models associate higher risk with active-duty status, Army or Marine Corps or Navy/Coast Guard service versus Air Force, combat deployment, low social support, life stressors, PTSD screens, and problem drinking.
