Weight Change Following US Military Service Int J Obes (Lond) 2013 Feb;37(2):244-53

Littman AJ, Jacobson IG, Boyko EJ, Powell TM, Smith TC, for the Millennium Cohort Study Team

This study provides the first prospectively collected evidence for an increased rate of weight gain around the time of military discharge that may explain previously reported higher rates of obesity in veterans, and identifies characteristics of higher-risk groups. Discharge from military service presents a window of risk and opportunity to prevent unhealthy weight gain in military personnel and veterans.

Utilizing Machine Learning To Predict Participant Response To Follow-Up Health Surveys in the Millennium Cohort Study Scientific Reports 2024 Oct 28 | doi: 10.1038/s41598-024-77563-8

Barkho W, Carnes NC, Kolaja CA, Tu XM, Boparai SK, Castañeda SF, Sheppard BD, Walstrom JL, Belding JN, Rull RP

Using various machine learning algorithms, patterns in response to prior surveys among Millennium Cohort Study participants improved the ability to predict future response to a follow-up survey.

US Military Deployment During 2001-2006: Comparison of Subjective and Objective Data Sources in a Large Prospective Health Study Annals of Epidemiology 2007 Dec;17(12):976-82

Smith B, Wingard DL, Ryan MAK, Macera CA, Patterson TL, Slymen DJ, for the Millennium Cohort Study Team

Defining military deployments using multiple data sources is examined. Deployment timing and duration metrics, critical for epidemiological studies, are valid in the Millennium Cohort Study.

Trajectories of Trauma Symptoms and Resilience in Deployed US Military Service Members: A Prospective Cohort Study British Journal of Psychiatry 2012 Apr;200(4):317-23

Bonanno GA, Mancini AD, Horton JL, Powell TM, LeardMann CA, Boyko EJ, Wells TS, Hooper TI, Gackstetter GD, Smith TC, for the Millennium Cohort Study Team

Symptoms of posttraumatic stress (PTS) were examined over time in relation to deployment. Four classes of PTS trajectories were identified for both single and multiple deployers, with over 80% of the deployers exhibiting a stable trajectory of low symptoms (i.e., resilience) pre- to post-deployment. Several factors predicting PTS trajectories were identified, which may direct future research aimed at decreasing the risk of posttraumatic stress disorder among deployers

Three-Item Dimensions of Anger Reactions Scale JAMA Network Open 2024 Feb 5 | doi: 10.1001/jamanetworkopen.2023.54741

Forbes D, LeardMann CA, Lawrence-Wood E, Villalobos J, Madden K, Gutierrez IA, Cowlishaw S, Baur J, Adler AB

Given the prevalence of problematic anger and its association with adverse outcomes, it is vital to develop a very brief measure that can be easily included in research and clinical contexts. Using data from two large military samples with current and former service members in Australia and the US, this study reported on a newly developed 3-item Dimensions of Anger Reactions (DAR-3) scale. The DAR-3 assesses anger intensity, frequency, and duration. Results were consistent across the samples in terms of the scales reliability, validity, and cut-off score. The DAR-3 has practical utility for military and veteran populations.

The US Department of Defense Millennium Cohort Study: Career Span and Beyond Longitudinal Follow-Up Journal of Occupational and Environmental Medicine 2009 Oct;51(10):1193-1201

Smith TS, for the Millennium Cohort Study Team

Describes the Millennium Cohort Study, a large longitudinal occupational health study designed and initiated prior to the combat deployments in Iraq and Afghanistan specifically to assess any short or long-term health outcomes during and after military service and career.

The Role of Posttraumatic Stress Symptoms and Negative Affect in Predicting Substantiated Intimate Partner Violence Incidents Among Military Personnel Military Behavioral Health 2021;9(4):442–462

Stander, VA, Woodall KA, Richardson SM, Thomsen CJ, Milner JS, McCarroll JE, Riggs DS, Cozza SJ, for the Millennium Cohort Study Team

Increasing rates of posttraumatic stress disorder (PTSD) in military populations may indicate heightened risk for aggression, including aggression among domestic partners. Using longitudinal data from the Millennium Cohort Study, we evaluated the association of PTSD symptom clusters and comorbid conditions as predictors of incidents of met criteria incidents of domestic abuse (physical and psychological) from DoD Family Advocacy Program (FAP) Central Registry data. Among 54,667 active-duty personnel who responded to the 2011 survey, FAP records documented 501 participants (1%) with incidents of emotional or physical met criteria incidents of aggression in the data collection period. Results showed that certain aspects of PTSD and behavioral health problems predicted incidents. In particular, general PTSD symptoms (e.g., anger/irritability, sleep disruption) and comorbid alcohol dependence were stronger predictors than trauma-specific PTSD symptomology (e.g., reexperiencing, hypervigilance). These results indicate that clinicians should consider the interpersonal consequences of PTSD and related behavioral problems.

The relative impact of injury and deployment on mental and physical quality of life among military service members PLoS One 2022 Sep 29 | doi: 10.1371/journal.pone.0274973

Kolaja CA, Castañeda SF, Woodruff SI, Rull RP, Armenta RF

Deployment and injury status was associated with poorer mental and physical quality of life (QOL) with clinically significant decreases in physical QOL observed for those who deployed and were injured, either in battle or nonbattle settings, compared with uninjured deployers.
