| Health Impact of US Military Service in a Large Population-Based Military Cohort: Findings of the Millennium Cohort Study, 2001-2008 | BMC Public Health | 2011 Jan;11(1):69 |
|
Smith TC, Jacobson IG, Hooper TI, LeardMann CA, Boyko EJ, Smith B, Gackstetter GD, Wells TS, Amoroso PJ, Gray GC, Riddle JR, Ryan MAK, for the Millennium Cohort Study Team This report summarizes findings from the Millennium Cohort Study through 2008 that have addressed health concerns related to military service. Conducting strategic studies aimed to identify, reduce, and prevent adverse health outcomes in military members have guided public health policy and will continue to affect policy for years to come. |

| Magnitude of Problematic Anger and its Predictors in the Millennium Cohort | BMC Public Health | 2020;20(1):1168 |
|
Adler AB, LeardMann CA, Roenfeldt KA, Jacobson IG, Forbes D Among sample of service members and Veterans (N= 90,266), 17% screened positive for problematic anger. Numerous independent factors were associated with an increased risk of problematic anger (e.g., PTSD, depression, financial problems, problem drinking) and decreased risk of problem anger (e.g., positive perspective, self-mastery). Developing interventions that target problematic anger in the military is critical given its high prevalence, distinction from other mental disorders, role in impeding effective PTSD treatment, and impact on vocational and interpersonal functioning. |

| Military service experiences and reasons for service separation among lesbian, gay, and bisexual individuals in a large military cohort | BMC Public Health | 2022 Jan 6;22(1):39 |
|
Carey FR, Jacobson IG, Lehavot K, LeardMann CA, Kolaja CA, Stander VA, Rull RP The goal of this study was to examine differences in military and service separation experiences by sexual orientation among a large representative sample of United States service members and veterans. Survey data from the 2016 Millennium Cohort Study follow-up questionnaire were used to assess sexual orientation (lesbian, gay, and bisexual [LGB] versus heterosexual) and military experiences and service separation experiences. Of the 99,599 participants, 3.4% identified as LGB. Those service members were more likely than their heterosexual peers to report feeling unimpressed by the quality of unit leadership, unsupported by the military, and negative about the military overall. LGB veterans were more likely than heterosexual peers of the same sex to separate from service for a variety of reasons (e.g., administrative, dissatisfaction with promotions/pay, disability/medical reasons, dissatisfaction with leadership and incompatibility with the military). Less positive military- and separation-specific experiences disproportionately affected LGB service members in this study. Promoting inclusion and increasing support for LGB service members may improve satisfaction with military service and retention. |

| 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. |

| 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 |

| New Onset and Persistent Symptoms of Posttraumatic Stress Disorder Self-Reported after Deployment and Combat Exposures: Prospective Population-Based US Military Cohort Study | British Medical Journal | 2008 Feb;336(7640):366-71 |
|
Smith TC, Ryan MAK, Wingard DL, Slymen DJ, Sallis JF, Kritz-Silverstein D, for the Millennium Cohort Study Team Findings define the importance of PTSD in this population and emphasize that specific combat exposures, rather than deployment itself, significantly affect the onset of PTSD symptoms postdeployment. |

| Baseline Self-Reported Functional Health Predicts Vulnerability to Posttraumatic Stress Disorder Following Combat Deployment: Prospective US Military Cohort Study | British Medical Journal | 2009 Apr;338:b1273 |
|
LeardMann CA, Smith TC, Smith B, Wells TS, Ryan MAK, for the Millennium Cohort Study Team Military service members who screen in the lowest 15% of health prior to combat exposure are more vulnerable to developing postdeployment PTSD. |

| Risk and Protective Factors for Cancer Mortality Among United States Service Members and Veterans (2001-2018) | Cancer Epidemiology, Biomarkers & Prevention | 2023 May 1 | doi: 10.1158/1055-9965.EPI-22-0943 |
|
Sharifian N, Carey FR, Seay JS, Castaneda SF, Boyko EJ, Rull RP This longitudinal study used data from the Millennium Cohort Study (2001-2018) to examine risk and protective factors for cancer mortality among service members and veterans. Compared with those who deployed without combat experiences, non-deployers were more likely to die from cancer, consistent with the healthy deployer effect. |

| Impact of Combat Deployment and Posttraumatic Stress Disorder on Newly Reported Coronary Heart Disease Among US Active Duty and Reserve Forces | Circulation | 2014;129:1813-1820 |
|
Crum-Cianflone NF, Bagnell ME, Schaller E, Boyko EJ, Smith B, Maynard C, Ulmer CS, Vernalis M and Smith TC This study evaluated the association of combat deployments and posttraumatic stress disorder (PTSD) on coronary heart disease among a young cohort of US service members. Experiencing combat deployment was associated with an increased odds of coronary heart disease by both self-report and medical record diagnosis after adjustment for demographic, military, and mental health characteristics. Screening positive for PTSD was not associated with CHD after adjustment. This study demonstrates that intense and acute stressful life experiences may increase the risk for coronary heart disease over a relatively short period among young adults. |

| A temporal analysis of mental health symptoms relative to separation from the military | Depression and Anxiety | 2022 Apr;39(4):334- 343 |
|
Porter B, Carey FR, Roenfeldt KA, Rull RP, Castro CA This paper examined mental health symptoms among 23,887 active duty Millennium Cohort Study participants who completed a survey within one year of their separation from the military. While significant, timing prior to or after separation did not have a practical impact on mental health among all study participants, accounting for less than 0.2% of variance in mental health symptoms. However, among participants with Other Than Honorable or General discharges, timing to separation accounted for 5.1% and 3.6% of the variance in posttraumatic stress disorder and depression symptoms, respectively; mental health symptoms increased among these participants around the time of separation and remained elevated in the period following separation. Increased outreach at the time of separation and post-separation is needed for service members with bad paper discharges. |
