Risk Factors for Homelessness Among Post-9/11 Era Veterans Armed Forces & Society 2024 July 25 | doi: 10.1177/0095327X241259080 | Online ahead of print

Metraux S, Kolaja CA, Crone B, Byrne T, Rull RP, Porter B

Between 2001 and 2016, approximately 2% of 49,323 post-9/11 era Veterans experienced homelessness after military separation.

All-Cause Mortality Among United States Military Personnel: Findings From the Millennium Cohort Study Annals of Epidemiology 2024 Aug 28 | doi: 10.1016/j.annepidem.2024.08.006 | Online ahead of print

Carey FR, Harbertson J, Sharifian N, Boyko EJ, Rull RP

Previous history of deployment, female sex, and Hispanic ethnicity were protective for mortality, while combat exposure, enlisted rank, being in the Army, and health factors (e.g., stressful life events, smoking, alcohol use) were risk factors for mortality among OEF/OIF/OND service members and veterans over a 20 year period.

Risk of Traumatic Brain Injury in Deployment and Nondeployment Settings Among Members of the Millennium Cohort Study Journal of Head Trauma Rehabilitation 2024 Jun 27 | doi: 10.1097/HTR.0000000000000970 | Online ahead of print

Jannace KC, Pompeii L, de Porras DGR, Perkison WB, Yamal JM, Trone DW, Rull RP

The risk of traumatic brain injury (TBI) was higher among service members in deployment settings compared to those in nondeployment settings. Risk reduction strategies and education are needed to reduce the occurrence of TBI based on deployment status and history.

Prospective Comparison of Risk Factors for Firearm Suicide and Non-Firearm Suicide in a Large Population-Based Cohort of Current and Former US Service Members: Findings from the Millennium Cohort Study The Lancet Regional Health Americas 2024 August | doi: 10.1016/j.lana.2024.100802

LeardMann CA, Sharifian N, Warner S, Boyko EJ, Boparai SK, Powell TM, Rull RP, Reger MA, Hoge CW, for the Millennium Cohort Study Team

In this prospective study of over 200,000 US current and former service members, risk factors were similar between firearm and non-firearm suicides. Suicide prevention and intervention strategies may benefit those at risk and may not need to be differentiated by specific demographic, military, or health factors.

Sleep Health Among US Navy Afloat Versus Ashore Personnel in the Millennium Cohort Study Journal of Sleep Research 2024 May 19 | doi:10.1111/jsr.14207 | Online ahead of print

Jacobson IG, Harbertson J, Sharifian N, Rull RP, Steele CT, Russell DW

Among 4,953 active-duty naval personnel who completed the 2014-2016 Millennium Cohort survey, sleep metrics (e.g., fatigue, short sleep duration) and sleep-related health outcomes (e.g., PTSD, depression) were similar between sailors with recent sea and shore duty, while sailors with recent shore duty had poorer physical health (e.g., type 2 diabetes, bodily pain) compared with those with recent sea duty.

Lifetime Traumatic Brain Injury and Risk of Post-Concussive Symptoms in the Millennium Cohort Study Journal of Neurotrauma 2024 March | doi: 10.1089/neu.2022.0213

Jannace K, Pompeii L, Gimeno Ruiz de Porras D, Perkison WB, Yamal JM, Trone DW, Rull RP

TBI was associated with greater risk of post-concussive symptoms (e.g., fatigue, poor concentration, memory loss) among active-duty service members with risk being greater as number of lifetime TBIs increased.

Posttraumatic Stress Disorder, Veterans Health Administration Use, and Care-Seeking Among Recent-Era U.S. Veterans Journal of Traumatic Stress 2024 June | doi: 10.1002/jts.23019

Porter B, Dozier ME, Seelig A, Zhu Y, Patoilo M, Boyko EJ, Rull RP

Veterans with probable PTSD were more likely to use Veterans Health Administration (VHA) services than veterans without probable PTSD. Among these veterans with probable PTSD, those with recent VHA use were more likely to have reported seeking care for PTSD compared to those who did not use VHA services in the past year.

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.

Racial, Ethnic, and Sex Disparities in Mental Health Among U.S. Service Members and Veterans: Findings from the Millennium Cohort Study American Journal of Epidemiology 2024 Feb 5 | doi: 10.1093/aje/kwad221

Sharifian N, Kolaja CA, LeardMann CA, Castañeda SF, Carey FR, Seay JS, Carlton KN, Rull RP, Millennium Cohort Study Team

Racial, ethnic, and sex disparities in mental health among service members and veterans persist, even after accounting for sociodemographic, military, health-related and social support factors. Despite increased availability to care among military populations, culturally relevant and targeted outreach are still needed to address these disparities.
