Title Publication Date/Location
Deployment-Related Depression Screening Results, 2001-2008: Comparing Clinical vs. Research Surveys American Journal of Preventative Medicine 2014 Nov;47(5):531-540

Welsh MM, PhD, Federinko SP, Burnett DG, Gackstetter GD, Boyko EJ, Seelig AD, Wells TS, and Hooper TI

This study compared depression symptoms reported on military-linked surveys, post-deployment health assessments, with responses from confidential surveys of the Millennium Cohort Study and then evaluated whether any factors were associated with discrepant responses. Moderate agreement was observed between paired survey responses. A higher proportion of active duty members, unmarried participants, and new accessions into military service endorsed depression symptoms on the confidential survey but not the military-linked survey. This study identifies potential subgroups to target for improving follow-up care for optimal mental health.

Disordered Eating and Weight Changes After Deployment: Longitudinal Assessment of a Large US Military Cohort American Journal of Epidemiology 2009 Feb;169(4):415-27

Jacobson IG, Smith TC, Smith B, Keel PK, Amoroso PJ, Wells TS, Bathalon GP, Boyko EJ, Ryan MAK for the Millennium Cohort Study Team

Deployed women who reported combat exposures represent a subgroup at higher risk for developing eating problems and weight loss postdeployment compared with deployed women who did not report combat exposures.

Early Mortality Experience in a Large Military Cohort and a Comparison of Data Sources Used for Mortality Ascertainment Population Health Metrics 2010 May;8(1):15

Hooper TI, Gackstetter GD, LeardMann CA, Boyko EJ, Pearse LA, Smith B, Amoroso PA, Smith TC, for the Millennium Cohort Study Team

This study assessed the ability of four different mortality data sources to document the early mortality experience of the Cohort. The strengths and limitations of each data source are described and support continued use of multiple sources for future mortality assessment.

Epidemiology of Inflammatory Bowel Disease Among Participants of the Millennium Cohort: Incidence, Deployment-Related Risk Factors, and Antecedent Episodes of Infectious Gastroenteritis Alimentary Pharmacology & Therapeutics 2017 Apr;45(8):1115-1127

Porter CK, Welsh M, Riddle MS, Nieh C, BoykoEJ, Gackstetter GD, Hooper TI

This study describes the incidence of and risk factors for two pathotypes of inflammable bowel disease (IBD), Crohn’s Disease (CD) and ulcerative colitis (UC) among Millennium Cohort Study participants using survey responses as well as data from post-deployment health assessments and medical encounters in the Military Health System. We observed that CD risk predictors included current smoking, two life stressors (vs. none), and prior irritable bowel syndrome. For UC, a dose-response relationship between the risk of UC and an increasing number of life stressors was observed. Antecedent infectious gastroenteritis was associated with an almost three-fold increase in risk in UC, but was not associated with CD. Stressful conditions along with infectious gastroenteritis are usual features of any deployment operation and may play a role in the development of IBD. However, observed differences in risk factors for UC and CD warrant further investigation.

Evaluation of a Modified Version of the Posttraumatic Growth Inventory-Short Form BMC Research Methodology 2017 Apr;17(1):69

Kaur N, Porter B, LeardMann CA, Tobin TE, Lemus H, Luxton DD

This study sought to validate a modified measure of posttraumatic growth, personal growth, and change that may occur following trauma. Results indicate that this modified measure may be used to assess well-being at one time point or growth over two time points. Furthermore, the two items assessing spirituality had a strong relationship with each other and may be used alone in future studies.

Examination of Post-Service Health-Related Quality of Life Among Rural and Urban Military Members of the Millennium Cohort Study Journal of Rural Social Sciences 2011;26(3):32-56

Proctor SP, Wells TS, Jones KA, Boyko EJ, Smith TC, for the Millennium Cohort Study Team

In this large population-based sample of young US veterans recently separated from military service, health-related quality of life (HRQL) was not significantly different among rural and urban residents in the adjusted analyses and deployment experience did not alter the association between the outcome and rural or urban residence. These results suggest that rural status is not independently associated with HRQL among recent U.S. veterans.

Exploratory Factor Analysis of Self-Reported Symptoms in a Large, Population-Based Military Cohort BMC Medical Research Methodology 2010 Oct;10(1):94

Kelton ML, LeardMann CA, Smith B, Boyko EJ, Hooper TI, Gackstetter GD, Bliese PD, Hoge CW, Smith TC, for the Millennium Cohort Study Team

Using exploratory factor analysis, this study examined mental and physical health symptom covariance structure. A 14-factor model accounted for 60% of the variance indicating a reasonable amount of construct overlap and that the number and type of questions appropriately assess a spectrum of heterogeneous symptoms.

Factors Associated With Persistent Posttraumatic Stress Disorder Among U.S. Military Service Members and Veterans BMC Psychiatry 2018 Feb 17;18(1):48

Armenta RF, Rush T, LeardMann CA, Millegan J, Cooper AD, Hoge, CW

Among service members and veterans who screened positive for PTSD at baseline, 47% met the criteria for persistent PTSD. Combat experiences and PTSD severity were found to be the most salient factors associated with persistent PTSD; other associated factors included co-morbid conditions, sleep problems, and somatic symptoms. These findings corroborate the need for more comprehensive and accessible treatment to address both PTSD symptoms and comorbid conditions.

Headache Disorders in the Millennium Cohort: Epidemiology and Relations with Combat Deployment Headache 2011 Jul-Aug;51(7);1098-1111

Jankosky C, Hooper TI, Granado NS, Scher A, Gackstetter GD, Boyko EJ, Smith TC, for the Millennium Cohort Study Team

Deployed personnel with reported combat exposure appear to represent a higher risk group for new-onset headache disorders. The identification of populations at higher risk for development of headache provides support for targeted interventions.

Health Care Utilization Among Complementary and Alternative Medicine Users in a Large Military Cohort BMC Complementary and Alternative Medicine 2011 Apr;11:27

White MR, Jacobson IG, Smith B, Wells TS, Gackstetter GD, Boyko EJ, Smith TC, for the Millennium Cohort Study Team

Our findings provide evidence that CAM users are utilizing more physician-based medical services than users of conventional care. Those using CAM account for 45.1% of outpatient care and 44.8% of inpatient care, but make up only 39% of the study population. Whether CAM use is supplementing current conventional medical practice to meet the health care needs of these individuals is not fully understood.
