The impact of military sexual trauma and warfare exposure on women veterans' perinatal outcomes

Development of the Ready to Care Survey for VA Women's Health Primary Care Provider

INTRODUCTION

Women Veterans are at increased risk for poor pregnancy outcomes and are increasingly using Veteran Affairs (VA) for maternity benefits. VA Women's Health Primary Care Providers (WH-PCPs) are well positioned to improve maternal outcomes for women Veterans, yet little is understood about their experience and comfort with perinatal care. The objective of this study was to develop and validate a survey that could be utilized to assess WH-PCPs' experience, comfort, and attitudes towards perinatal care.

METHODS

After a review of the literature, we adapted a previously published survey to address four content areas including clinical experience, comfort level, and attitudes towards perinatal care and knowledge of VA specific maternity services. This survey was piloted with five WH-PCPs before undergoing two rounds of content validation with content experts. Content validity indexes (CVI) were calculated based on the content experts' ratings. Qualitative feedback from the content experts were summarized and reviewed by the research team. The CVI and qualitative responses were utilized to guide the decision to revise, refine, or delete survey questions.

RESULTS

After the first round of content validation, we deleted three questions, revised three questions, and add three questions to the content areas of clinical experience and comfort. In the domain of attitudes towards perinatal care, we deleted one question and revised two questions and three questions were added to the knowledge of VA specific maternity services domain. After the second round of content validation, only one question was deleted from the attitudes domain.

DISCUSSION

We developed and validated the Ready to Care Survey for VA WH-PCP using two rounds of content validation. The final survey had face and content validity. This survey tool can be used to assess VA WH-PCP's knowledge and readiness in caring for Veterans of child-bearing age for operational and research needs.

Effect of active-duty military service on neonatal birth outcomes: a systematic review

INTRODUCTION

Increasing numbers of women serve in the armed forces in countries worldwide. Stress experienced during pregnancy is associated with adverse birth outcomes including preterm delivery (PTD) and low birth weight (LBW). Several characteristics of military employment and lifestyle can increase stress acting on active-duty servicewomen (ADSW) and hence may increase the risk of adverse neonatal outcomes. This paper reviews the prevalence of PTD, preterm labour (PTL), LBW and stillbirth in babies born to ADSW in the armed forces.

METHODS

This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. Medline, EMBASE, Web of Science, Global Health and CINAHL Plus databases were searched from inception to July 2021 (November 2023, EMBASE) using subject heading and keyword searches for English language journal articles on babies born to ADSW in any military branch and any country. The Joanna Briggs Institute prevalence critical appraisal tool assessed risk of bias in included papers. Studies were paired with a comparator non-active-duty population to generate a prevalence ratio as the effect measure. A narrative synthesis was conducted.

RESULTS

21 observational studies fulfilled the eligibility criteria. They were all conducted in the US military, involved a total of 650 628 participants, and were published between 1979 and 2023. Their results indicate increased LBW in ADSW compared with non-service women. There was insufficient evidence to conclude or rule out whether ADSW have increased rates of PTD or PTL.

CONCLUSIONS

ADSW may be at increased risk of having an LBW baby. However, caution is needed if seeking to generalise the findings beyond the US context. This review highlights a growing need for female-specific research in other armed forces and, specifically, into reproductive health. Such research is necessary to inform military maternity pathways and policies in ways that safeguard mothers and their babies while enhancing military readiness.

Ethnoracial Disparities in Perinatal Outcomes among Women Veterans

Objective: Non-Hispanic Black women have increased rates of preterm birth and low infant birth weight. However, we do not know if these disparities replicate in women veterans, a population that may be at further risk for poor perinatal outcomes. This study sought to examine ethnoracial differences in preterm birth and low infant birth weight in veterans. Methods: A national sample of randomly chosen women veterans (i.e., oversampled for residency in high crime neighborhoods) reported information about all pregnancies they have had in their life, demographic characteristics, and history of childhood trauma exposures. The analytic sample was limited to individuals who identified as Hispanic/Latinx, Black, or White (n = 972). Mixed-effects regression models were used to examine ethnoracial differences in gestational age at delivery and infant birth weight, controlling for age at pregnancy, childhood trauma exposure, pregnancy during military service, income, and education. Results: Both Black and Hispanic/Latinx veterans were significantly more likely to have an infant born at lower gestational age (B = -1.04 and B = -1.11, respectively) and lower infant birth weight (B = -195.83 and B = -144.27, respectively) as compared with White veterans in covariate-adjusted models. Black (odds ratio = 3.24, confidence interval = 1.16, 9.09) veterans were more likely to meet the clinical definition of preterm birth as compared with White veterans. Conclusions: Results align with what is seen in the general population regarding ethnoracial disparities in gestational age at delivery and infant birth weight. Findings highlight the critical need for more research on mechanisms and prevention efforts for ethnoracial disparities in perinatal outcomes.

The Impact of Military Trauma Exposures on Servicewomen's Pregnancy Outcomes: A Scoping Review

INTRODUCTION

Active-duty servicewomen and veterans make up nearly 20% of the United States military and may experience trauma specific to military service. Military-specific trauma includes combat deployment and military sexual trauma, exposure to which may result in posttraumatic stress disorder (PTSD). The purpose of this scoping review is to examine the extent to which military trauma exposures impact the pregnancy outcomes of active-duty servicewomen and women veterans.

METHODS

A systematic search of OVID MEDLINE, OVID Embase, and OVID PsycINFO from inception to September 25, 2023, identified studies examining associations between military trauma exposures and perinatal outcomes. Of the 614 studies identified, 464 were reviewed for relevance, with 16 meeting inclusion criteria.

RESULTS

Of the 16 included studies, 14 found associations between military trauma exposure and adverse pregnancy outcomes including preterm birth, gestational diabetes, hypertensive disorders of pregnancy, low birth weight, and perinatal mood and anxiety disorders. The risks of adverse pregnancy outcomes increased with the severity of PTSD, the recency of combat deployment, and repetitive deployment.

DISCUSSION

This scoping review strengthens the link between trauma exposures and adverse pregnancy outcomes for current and former military servicewomen. A gap in the literature persists regarding trauma exposure among active-duty servicewomen, which differs significantly from women veterans. As mental health conditions are the leading underlying cause of maternal mortality, standardized screening during the perinatal period for military-specific trauma exposures and PTSD is recommended for this population. Black servicewomen of junior enlisted rank carry disproportionate burdens of PTSD diagnosis and adverse pregnancy outcomes. Comprehensive prenatal and postpartum management may improve perinatal and neonatal outcomes for military servicewomen and provide an innovative approach to reducing existing racial disparities.

Nonsuicidal self-injury methods among U.S. Veterans: Latent class analysis and associations with psychosocial outcomes

Nonsuicidal self-injury (NSSI) is a debilitating concern among U.S. veterans, with wall/object-punching commonly endorsed as an NSSI method. We examined how this behavior relates to other NSSI methods and psychosocial outcomes. We conducted a latent class analysis (LCA) of NSSI methods among 1,138 Gulf War Era veterans, (77.9% male), 21.7% of whom endorsed lifetime NSSI. We categorized classes based on their associations with age, sex, combat and military sexual assault exposure, then examined the association of class membership with psychosocial indicators. LCA results supported four classes: 1) High punching/banging NSSI (2.5%); 2) Multimethod NSSI methods (6.3%); 3) High-risk, multimethod NSSI (3.1%); and 4) Low-risk NSSI (88.1%). Psychosocial indicators (suicide attempt, ideation, possible depressive or posttraumatic stress disorders, poor psychosocial functioning) were worse for members of the NSSI classes versus those in the low-risk group. A subset of U.S. veterans may engage in NSSI primarily via punching/banging methods. All patterns of NSSI engagement were associated with negative psychosocial outcomes relative to those in the low-risk class of the behavior.

Understanding the Mental Health Impact of Previous Pregnancy Loss Among Currently Pregnant Veterans

BACKGROUND

Pregnancy loss, including miscarriage and stillbirth, is common and associated with an increased risk for prenatal and postnatal depression, as well as posttraumatic stress disorder (PTSD). Racial disparities have been observed in pregnancy loss, with Black women having higher rates of pregnancy loss and postnatal depression. However, no research to date has examined the mental health and demographic correlates of pregnancy loss within a veteran population.

METHOD

The current study examined associations between pregnancy loss and mental health and demographic correlates among 1,324 pregnant veterans, of which 368 had a history of at least one stillbirth and/or miscarriage.

RESULTS

Veterans with a history of pregnancy loss, compared with those without, were more likely to have a diagnosis of anxiety (52.7% vs. 46.4%, p = .04), depression (62.5% vs. 50.8%, p = .0001), or PTSD (46.5% vs. 37.6%, p = .003); were more likely to report receiving mental health care during pregnancy (23.1% vs. 16.8%, p = .01); and were more likely to have experienced military sexual trauma (harassment: 56.5% vs. 49.9%, p = .04; rape: 38.9% vs. 29.3%, p = .0004). Results also indicated that Black veterans were more likely to report a history of pregnancy loss (32.1% vs. 25.3%, p = .01). Further, Black veterans were more likely to experience clinically meaningful prenatal depression symptoms (adjusted odds ratio: 1.90; 95% confidence interval: 1.42-2.54) after accounting for past loss and age in logistic regression models.

DISCUSSION

Taken together, findings from the present investigation corroborate previous research highlighting the deleterious impact of pregnancy loss and extend prior work by examining these associations among a diverse sample of pregnant veterans.

PTSD and Depression Symptoms Increase Women's Risk for Experiencing Future Intimate Partner Violence

Psychological distress may impact women's risk for future intimate partner violence (IPV). Yet, limited research has utilized longitudinal research designs and there is a scarcity of research looking at the three most commonly implicated mental health factors-posttraumatic stress disorder (PTSD), depression, and alcohol use-within the same study. Research is especially scarce for women veterans, who experience substantial risk for these mental health concerns and experiencing IPV. This study examined the role of PTSD symptoms, depression symptoms, and alcohol use in increasing risk for experiencing future IPV while simultaneously accounting for the impact of recent IPV experience on subsequent mental health. This study included a sample of 1921 women veterans (M_age = 36.5), who were asked to complete three mail surveys over the course of 8 months as part of a larger longitudinal survey study of US veterans' health and well-being. The survey assessed experiences of IPV, PTSD symptoms (PCL-5), depression symptoms (PHQ-9), and alcohol use (AUDIT-C) at each of the three time points. Results from separate path analysis models provided support for the role of PTSD symptoms and depression symptoms (but not alcohol use) in increasing risk for IPV experience over time. However, the path analysis models provided little support, with the exception of PTSD, for the impact of IPV experience on subsequent mental health symptoms. Findings point to the importance of better understanding the mechanisms by which PTSD and depression symptoms can increase risk for IPV to inform theory and prevention and treatment efforts. Detection and treatment of PTSD and depression symptoms among women may help reduce risk for future violence in intimate relationships.

State of the Knowledge of VA Military Sexual Trauma Research

Despite substantial efforts to counter sexual assault and harassment in the military, both remain persistent in the Armed Services. In February 2021, President Biden directed the U.S. Department of Defense to establish a 90-day Independent Review Commission on Sexual Assault in the Military (IRC) to assess the department's efforts and make actionable recommendations. As servicemembers discharge from the military, effects of military sexual trauma (MST) are often seen in the Veterans Health Administration (VA). In response to an IRC inquiry about VA MST research, we organized an overview on prevalence, adverse consequences, and evidence-based treatments targeting the sequelae of MST. Women are significantly more likely to experience MST than their male counterparts. Other groups with low societal and institutional power (e.g., lower rank) are also at increased risk. Although not all MST survivors experience long-term adverse consequences, for many, they can be significant, chronic, and enduring and span mental and physical health outcomes, as well as cumulative impairments in functioning. Adverse consequences of MST come with commonalities shared with sexual trauma in other settings (e.g., interpersonal betrayal, victim-blaming) as well as unique aspects of the military context, where experiences of interpersonal betrayal may be compounded by perceptions of institutional betrayal (e.g., fear of reprisal or ostracism, having to work/live alongside a perpetrator). MST's most common mental health impact is posttraumatic stress disorder, which rarely occurs in isolation, and may coincide with major depression, anxiety, eating disorders, substance use disorders, and increased suicidality. Physical health impacts include greater chronic disease burden (e.g., hypertension), and impaired reproductive health and sexual functioning. Advances in treatment include evidence-based psychotherapies and novel approaches relying on mind-body interventions and peer support. Nonetheless, much work is needed to enhance detection, access, care, and support or even the best interventions will not be effective.
