Chronic multisymptom illness among female Veterans deployed to Iraq and Afghanistan.
Mohanty, April F, Muthukutty, Anusha, Carter, Marjorie E et al. · Medical care · 2015 · DOI
Quick Summary
This study looked at how common chronic multisymptom illnesses—including chronic fatigue syndrome, fibromyalgia, and irritable bowel syndrome—are among female veterans who deployed to Iraq and Afghanistan. Researchers found that these conditions were more than twice as common in this group compared to other female veterans. The study suggests that deployment experiences may play a role in developing these illnesses.
Why It Matters
This work demonstrates that female combat veterans experience substantially elevated rates of ME/CFS and related multisymptom illnesses compared to general female veteran populations, highlighting a vulnerable subgroup requiring enhanced clinical recognition. Understanding deployment-related factors contributing to CMI prevalence may inform screening protocols and targeted interventions for this population.
Observed Findings
CMI-related diagnoses (CFS, fibromyalgia, IBS) were present in 8.2% of female OEF/OIF/OND Veterans (n=6,397) versus 3.9% in all female VHA users—more than twice the prevalence.
Statistically significant differences existed in age, education, marital status, military component, and service branch between females with and without CMI diagnoses.
Females with CMI diagnoses had higher proportions of depression and/or PTSD diagnoses compared to those without CMI.
CMI diagnoses were primarily identified in primary care, women's health, and physical medicine and rehabilitation clinical settings.
Inferred Conclusions
Female OEF/OIF/OND deployed Veterans experience disproportionately high rates of chronic multisymptom illness compared to the general female Veteran population.
Deployment-related experiences may contribute to CMI development, though the mechanisms remain unclear.
Mental health comorbidities are associated with CMI diagnosis in this population, warranting investigation of their role as confounders or mediators.
Enhanced screening protocols for CMI in female Veterans and evaluation of deployment-specific care models are needed.
Remaining Questions
Does deployment exposure directly cause CMI, or do deployment-related factors (trauma, stress, environmental exposures) act through mental health pathology?
What This Study Does Not Prove
This study does not prove that deployment causes CMI, only that these conditions occur more frequently in deployed veterans—causality cannot be established from cross-sectional data. The role of mental health diagnoses (depression, PTSD) as confounders versus mediators of the deployment-CMI relationship remains unclear. The study also cannot determine whether coding practices or true disease prevalence differences account for the observed differences.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
What specific deployment experiences or military exposures are most strongly associated with CMI development in female Veterans?
How do diagnostic coding practices and healthcare-seeking behavior differ between deployed and non-deployed female Veterans, and to what extent do these explain the prevalence difference?
What models of integrated care most effectively manage CMI in this population, and how should clinical screening protocols be adapted?
