Measuring Aggregated and Specific Combat Exposures: Associations Between Combat Exposure Measures and Posttraumatic Stress Disorder, Depression, and Alcohol-Related Problems Journal of Traumatic Stress 2018 Apr;31:296-306

Porter B, Hoge CW, Tobin LE, Donoho CJ, Castro CA, Luxton DD, Faix D

This study compared two measures of combat exposure and showed that both measures were similarly predictive of poor mental health. The unique contributions of specific exposures to poor mental health were also examined. While all combat exposure items were related to poor mental health, relatively stronger independent associations were observed for certain exposures (e.g., witnessing instances of physical abuse).

Posttraumatic Stress Disorder Symptom Clusters in Service Members Predict New-Onset Depression Among Military Spouses Journal of Traumatic Stress 2020 Sep 3. doi: 10.1002/jts.22575

Walter KH, LeardMann CA, Carballo CE, McMaster HM, Donoho CJ, & Stander VA

Among spouses of service members with probable posttraumatic stress disorder (PTSD), 14% met criteria for new-onset depression over a 3-year period. The service member’s PTSD symptom cluster of effortful avoidance was associated with an increased risk of new-onset depression in spouses, underscoring the impact of service member psychological symptoms on the spouse.

A Comparison of Mental Health Outcomes in Persons Entering US Military Service Before and After September 11, 2001 Journal of Traumatic Stress 2012 Feb;25: 17-24

Wells TS, Ryan MAK, Jones KA, Hooper TI, Boyko EJ, Jacobson IG, Smith TC, Gackstetter GD, for the Millennium Cohort Study Team

It is hypothesized that those who entered military service prior to September 11, 2001 might have had expectations of experiencing a regular operational tempo and less combat compared with those entering service after this date, therefore an increased risk for mental disorders. Although measuring the direct reason for entering the military was not possible for this study, the findings showed that those entering pre-September 11 did not have a higher odds of mental disorders, suggesting that mental disorders resulting from the experience of war are common across the pre- and post-September 11 accession eras.

Posttraumatic Stress Disorder and Depression Among US Military Health Care Professionals Deployed in Support of the Operations in Iraq and Afghanistan Journal of Traumatic Stress 2012 Dec;25(6):616-23

Jacobson IG, Horton JL, LeardMann CA, Ryan MAK, Boyko EJ, Wells TS, Smith B, Smith TC, for the Millennium Cohort Study Team

Among military personnel deployed with combat experience, health care professionals did not have increased odds for new-onset PTSD or depression over time compared to individuals in other occupations. Combat experience significantly increased the odds for new-onset PTSD or depression among deployed health care professionals, suggesting that combat experience, not features specific to being a health care professional, was the key exposure explaining development of these outcomes.

Posttraumatic Stress Disorder, Veteran Health Administration, Use and Care Seeking Among Post 9/11 U.S. Veterans Journal of Traumatic Stress 2024 Feb 29 | doi: 10.1002/jts.23019 | Online ahead of print

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.

Is Military Deployment a Risk Factor for Maternal Depression? Journal of Women's Health 2013 Jan; 22(1):9-18

Nguyen S, LeardMann CA, Smith B, Conlin AMS, Slymen DJ, Hooper TI, Ryan MAK, Smith TC, for the Millennium Cohort Study Team

This study found that military women who recently gave birth and then deployed with combat experience had an increased risk for depression. Combat experience primarily increased the risk for depression, rather than childbirth itself. In addition, deployment without combat experience was not significantly associated with maternal depression among women who recently gave birth.

US Naval and Marine Corps Occupations, PTSD and Depression Risk and Absenteeism Journal of Workplace Behavioral Health 2014;29(2):91–112

Wells TS, Bagnell ME, Miller SC, Smith TC, Gackstetter GD and Boyko EJ for the Millennium Cohort Study Team

This study investigated whether military occupation was associated with PTSD or depression, and if PTSD or depression was associated with lost workdays among US Navy and US Marine personnel. Navy personnel in service and supply occupations were 85% more likely to screen positive for new-onset PTSD, while those serving in health care were 58% more likely to screen positive for new-onset depression compared to other occupations. In addition, those with new-onset and persistent PTSD were twice as likely to miss one or more days of work. This suggests that early identification and management of these conditions may improve force readiness.

Surveillance Snapshot: Cervical Screening among U.S. Military Servicewomen in the Millennium Cohort Study, 2003–2015 Medical Surveillance Monthly Report 2020 Jul;27(7):15

Matsuno RK, Porter B, Warner SG, Wells N for the Millennium Cohort Study Team

Across a 13 year period (2003-2015), the percentage of U.S. service women who were up-to-date with cervical cancer screening peaked in 2010, then declined. Screening was generally highest among Air Force personnel and lowest among Navy personnel. Being up-to-date was higher for servicewomen who had initiated the HPV vaccine than for women who had not.

Surveillance Snapshot: Human Papillomavirus Vaccination Among U.S. Active Component Service Members in the Millennium Cohort Study, 2006–2017 Medical Surveillance Monthly Report 2019 Jun;26(6):18

Matsuno RK, Porter B, Warner SG, Wells N

Among a sample of active component members under the age of 26, (22,387 service women and 31,705 service men), service more women (37.8%) were more likely than service men (3.9%) to initiate receiving the HPV vaccine. Among those who initiated the vaccine, 40.2% of women and 23.1% of men were adherent to receiving all 3 doses within 1 year. Members of the Air Force and those in healthcare occupations had higher percentages of HPV vaccine initiation and adherence.

Brief Report: Menstrual Suppression Among U.S. Female Service Members in the Millennium Cohort Study Medical Surveillance Monthly Report 2022 Sept 29(9), 19-22

Zhu Y, Kolaja CA, Stamas N, Matsuno RK, Rull RP; Millennium Cohort Study Team

This study examined the prevalence of self-reported menstrual suppression among U.S. female active duty personnel (N=22,920) at two time points (2008, 2013) by demographic and military characteristics. Menstrual suppression increased significantly overall from 2008 (2.5%) to 2013 (3.8%) and among younger age groups (aged 18-34), non-Hispanic White individuals, Army, Navy, or Air Force personnel. The highest prevalence of menstrual suppression was reported in 2013 among those who deployed in the past year (4.7%) or worked in health care (5.1%) or combat specialties (4.7%). Increased health education is needed to support the health care needs and readiness of female service members.
