Sexual Health Problems among Service Men: The Influence of Posttraumatic Stress Disorder Journal of Sex Research 2021 Jan 11:1-13

Kolaja CA, Roenfeldt K, Armenta RF, Schuyler AC, Orman JA, Stander VA, LeardMann CA

Among service men, numerous factors (e.g. older age, lower education, enlisted paygrade, disabling injury, BMI) were associated with sexual health problems. PTSD mediated the associations between stressors (combat deployment and sexual assault) and sexual health outcomes. These findings indicate that sexual health is negatively affected by military-related stressors and comprehensive treatment options are warranted.

Multiple imputation validation study: Addressing unmeasured survey data in a longitudinal design BMC Medical Research Methodology 2021 Jan 6;21(1):5

Kolaja CA, Porter B, Powell TM, Rull RP, Millennium Cohort Study Team

This study examined the efficiency and feasibility of multiple imputation (MI) to recover data from a question completely missing at a follow-up survey assessment. Specifically, the suicidal ideation item on the depression module of the Patient Health Questionnaire was set to missing on a follow-up survey and then filled in using different MI models. Imputed and self-reported suicidal ideation were similarly associated with the related constructs of sleep duration and smoking status, suggesting that MI allowed for the inclusion of an otherwise missing item as a covariate in statistical models.

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.

Longitudinal Investigation of Military-Specific Factors Associated with Continued Unhealthy Alcohol Use Among a Large US Military Cohort Journal of Addiction Medicine 2020 Jul-Aug; 14(4): e53–e63

Jacobson IG, Williams EC, Seelig AD, Littman AJ, Maynard CC, Bricker JB, Rull RR, Boyko EJ, for the Millennium Cohort Study Team

This study examined military-specific risk factors for continued unhealthy alcohol use (e.g. heavy weekly, heavy episodic, and problem drinking) among service members screening positive on two consecutive surveys. Service members in the Reserve/Guard (compared with Active Duty) and those who separated from military service during follow-up (compared with those remaining on active service) had an elevated risk for continuing unhealthy drinking across all three dimensions of unhealthy alcohol use.

Hypertension in Military Veterans Is Associated With Combat Exposure and Combat Injury Journal of Hypertension 2020 Jul;38(7):1293-1301

Howard JT, Stewart IJ, Kolaja C, Sosnov JA, Rull R, Torres I, Janak JC, Walker LE, Trone DW, Armenta RF

This study examined the association between combat injury and incident hypertension. We found that those who were injured during combat were more likely to develop hypertension. Further, inadequate sleep, having PTSD, and being overweight or obese were associated with developing hypertension. Results highlight the importance of hypertension prevention among those who are injured during their time in service.

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.

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.

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.

Mental Health, Physical Health, and Health-Related Behaviors of U.S. Army Special Forces PLOS One 2020 Jun 3;15(6):e023356

Cooper AD, Warner SG, Rivera AC, Rull RP, Adler AB, Faix DJ, Neff RR, Deagle EA, Caserta RJ, LeardMann CA, for the Millennium Cohort Study Team

Using prospective data, Army Special Forces personnel and Ranger Qualified infantrymen reported fewer mental health problems, multiple somatic symptoms, and unhealthy behaviors than General Purpose Forces infantrymen. Findings indicate that the adoption of healthy behaviors, such as adequate sleep and physical activity, may be an efficient and cost-effective approach for preventing adverse health outcomes, regardless of occupational specialization or prior health status.
