Deployment and Preterm Birth Among US Army Soldiers

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.

Maternal and Neonatal Outcomes of Adolescent Pregnancies in the Military Health System

OBJECTIVE

To determine if universal access to care for military beneficiaries improves timing of presentation to prenatal care (PNC) in adolescent and young adult (AYA) pregnancies, improving maternal and neonatal outcomes.

STUDY DESIGN

Retrospective descriptive cohort study, which assessed PNC initiation in eligible military beneficiaries: dependent daughters, active-duty women, and active-duty spouses aged 13 to 26 between January 2015 and December 2019, and subsequent adverse maternal and neonatal outcomes.

RESULTS

The cohort included 4,557 eligible pregnancies and 4,044 mothers aged 13 to 26. Late entry to PNC was not associated with gestational diabetes, prolonged rupture of membranes, pregnancy loss, elective abortion, substance use, or premature labor. Younger age was significantly associated with substance use, elective abortion, and sexually transmitted infection. There were 2,107 eligible newborns. There was no significant difference in gestational age at birth, incidence of prematurity, birthweight percentile, or occurrence of a neonatal intensive care unit admission based on maternal age. In comparison to published national outcomes, there was a significantly smaller occurrence of preterm (5.3% vs. 9.57-10.23%, 95% CI, 4.4-6.4%), small for gestational age (5.2% vs. 10-13%, 95% CI, 4.3-6.2%), and large for gestational age (4.8% vs. 9%, 95% CI, 4.0-5.8%) births, but a higher occurrence of neonatal intensive care unit admissions (16.9% vs. 7.8-14.4%, 95% CI, 15.4-18.6%) in infants born to military beneficiaries.

CONCLUSIONS

Our findings suggest that expanded universal access to health care may improve AYA pregnancy and delivery outcomes. Infants born to AYA military beneficiaries have improved neonatal outcomes compared to nationally published data. These results may correlate to improved maternal access within a free or low-cost healthcare system.

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.

Postpartum long-acting reversible contraceptive use among active-duty, female US Army soldiers

BACKGROUND

Postpartum use of long-acting reversible contraception has been found to be effective at increasing interpregnancy intervals, reducing unintended pregnancies, and optimizing health outcomes for mothers and babies. Among female active-duty military service members, reproductive planning may be particularly important, yet little is known about postpartum long-acting reversible contraceptive use among active-duty soldiers.

OBJECTIVE

This study aimed to (1) quantify postpartum uptake of long-acting reversible contraception among active-duty female US Army soldiers and (2) identify demographic and military-specific characteristics associated with use.

STUDY DESIGN

This retrospective cohort study used longitudinal data of all digitally recorded health encounters for active-duty US Army soldiers from 2014 to 2017. The servicewomen included in our analysis were aged 18 to 44 years with at least one delivery and a minimum of 4 months of total observed time postdelivery within the study period. We defined postpartum long-acting reversible contraception use as initiation of use within the delivery month or in the 3 calendar months following delivery and identified likely immediate postpartum initiation via the proxy of placement recorded during the same month as delivery. We then evaluated predictors of postpartum long-acting reversible contraception use with multivariable logistic regression.

RESULTS

The inclusion criteria were met by 15,843 soldiers. Of those, 3162 (19.96%) initiated the use of long-acting reversible contraception in the month of or within the 3 months following delivery. Fewer than 5% of these women used immediate postpartum long-acting reversible contraception. Among women who initiated postpartum long-acting reversible contraceptive use, 1803 (57.0%) received an intrauterine device, 1328 (42.0%) received an etonogestrel implant, and 31 received both (0.98%). Soldiers of younger age, self-reported White race, and those who were married or previously married were more likely to initiate long-acting reversible contraception in the postpartum period. Race-stratified analyses showed that self-reported White women had the highest use rates overall. When compared with these women, the adjusted odds of postpartum use among self-reported Black and Asian or Pacific Islander women were 18% and 30% lower, respectively (both P<.001). There was also a trend of decreasing postpartum use with increasing age within each race group. Differences observed between age groups and race identities could partially be attributed to differential use of permanent contraception (sterilization), which was found to be significantly more prevalent among both women aged 30 years or older and among women who identified as Black.

CONCLUSION

Among active-duty US Army servicewomen, 1 in 5 used postpartum long-acting reversible contraception, and fewer than 5% of these women used an immediate postpartum method. Within this population with universal healthcare coverage, we observed relatively low rates of use and significant differences in the uptake of effective postpartum long-acting contraceptive methods across self-reported race categories.

Considerations for the provision of PTSD treatment among pregnant women with substance use histories: A clinical conceptual model based on case consultation field notes

OBJECTIVE

Increasing prevalence of substance use in pregnancy presents a public health crisis that is compounded by posttraumatic stress disorder (PTSD) comorbidity. We aimed to detail the clinical complexities of PTSD treatment provision among pregnant women with substance use histories.

METHODS

We conducted a qualitative study using clinical case consultation field notes (N = 47 meetings) which were gathered during a hybrid effectiveness-implementation pilot study of Written Exposure Therapy (WET) for PTSD among pregnant women seen in an obstetrics-SUD clinic [2019-2021]. Patient baseline survey data (N = 25) were used to characterize the sample and contextualize engagement.

RESULTS

Participants were exposed to a high number of trauma/adversity event types. There was no association between number of trauma/adversity event types and treatment response or dropout. Qualitative findings revealed clinical features relevant to PTSD treatment, including multi-system involvement; parental trauma and substance use; relevance of substance use to trauma context and posttraumatic cognitions, emotions, and behaviors; impact of trauma on experiences of pregnancy, attachment, and child rearing; limited social networks placing women at risk of ongoing violence; and experiences of substance use discrimination.

CONCLUSION

PTSD treatment among pregnant women with substance use histories is highly important to maternal-child health.

Physical Fitness in Relationship to Depression and Post-Traumatic Stress Disorder During Pregnancy Among U.S. Army Soldiers

Background: Depression and post-traumatic stress disorder (PTSD) are prevalent in pregnancy, especially among military members. These conditions can lead to adverse birth outcomes, yet, there's a paucity of evidence for prevention strategies. Optimizing physical fitness is one understudied potential intervention. We explored associations between prepregnancy physical fitness and antenatal depression and PTSD in soldiers. Materials and Methods: This was a retrospective cohort study of active-duty U.S. Army soldiers with live births between 2011 and 2014, identified with diagnosis codes from inpatient and outpatient care. The exposure was each individual's mean Army physical fitness score from 10 to 24 months before childbirth. The primary outcome was a composite of active depression or PTSD during pregnancy, defined using the presence of a code within 10 months before childbirth. Demographic variables were compared across four quartiles of fitness scores. Multivariable logistic regression models were conducted adjusting for potential confounders selected a priori. A stratified analysis was conducted for depression and PTSD separately. Results: Among 4,583 eligible live births, 352 (7.7%) had active depression or PTSD during pregnancy. Soldiers with the highest fitness scores (Quartile 4) were less likely to have active depression or PTSD in pregnancy (Quartile 4 vs. Quartile 1 adjusted odds ratio 0.55, 95% confidence interval 0.39-0.79). Findings were similar in stratified analyses. Conclusion: In this cohort, the odds of active depression or PTSD during pregnancy were significantly reduced among soldiers with higher prepregnancy fitness scores. Optimizing physical fitness may be a useful tool to reduce mental health burden on pregnancy.

An exploratory analysis of factors associated with spontaneous preterm birth among pregnant veterans with post-traumatic stress disorder

BACKGROUND

Pregnant veterans with post-traumatic stress disorder (PTSD) are at increased risk for spontaneous preterm birth, yet the underlying reasons are unclear. We examined factors associated with spontaneous preterm birth among pregnant veterans with active PTSD.

METHODS

This was an observational study of births from administrative databases reimbursed by the Veterans Health Association (VA) between 2005 and 2015. Singleton livebirths among veterans with active PTSD within 12 months prior to childbirth were included. The primary outcome was spontaneous preterm birth. Maternal demographics, psychiatric history, and pregnancy complications were evaluated as exposures. Covariates significant on bivariate analysis, as well as age and race/ethnicity as a social construct, were included in multivariable logistic regression to identify factors associated with spontaneous preterm birth. Additional analyses stratified significant covariates by the presence of active concurrent depression and explored interactions between antidepressant use and preeclampsia.

RESULTS

Of 3,242 eligible births to veterans with active PTSD, 249 (7.7%) were spontaneous preterm births. The majority of veterans with active PTSD (79.1%) received some type of mental health treatment, and active concurrent depression was prevalent (61.4%). Preeclampsia/eclampsia (adjusted odds ratio [aOR] 3.30, 95% confidence interval [CI] 1.67-6.54) and ≥6 antidepressant medication dispensations within 12 months prior to childbirth (aOR 1.89, 95% CI 1.29-2.77) were associated with spontaneous preterm birth. No evidence of interaction was seen between antidepressant use and preeclampsia on spontaneous preterm birth (p=0.39). Findings were similar when stratified by active concurrent depression.

CONCLUSION

Among veterans with active PTSD, preeclampsia/eclampsia and ≥6 antidepressant dispensations were associated with spontaneous preterm birth. While the results do not imply that people should discontinue needed antidepressants during pregnancy in veterans with PTSD, research into these factors might inform preterm birth prevention strategies for this high-risk population.

Sufficiency of Health Information During Pregnancy: What's Missing and for Whom? A Cross-Sectional Analysis Among Veterans

Background: Women Veterans often experience trauma and physical and mental health conditions that increase risk of adverse pregnancy outcomes. Information provision during pregnancy may facilitate improved outcomes. However, little evidence exists about information women Veterans receive during pregnancy, and their perceptions of it. Materials and Methods: We recruited pregnant Veterans from 15 Veterans Affairs medical centers. Through telephone surveys, women (N = 851) provided information about sociodemographic characteristics, military service, health, and pregnancy experiences. We asked postpartum women whether, during pregnancy, they received sufficient information about nine health topics. We calculated a composite score (range: 0-9) that reflected sufficiency of information received. Multivariable logistic regression models identified determinants of perceived sufficiency of information. Results: Mean age was 32.1 years. Most reported being White (56.3%), non-Hispanic (80.3%), married/living with a partner (85.1%), and employed (54.4%). Most (54.6%) had been diagnosed with depression (54.6%); one-quarter reported current depressive symptoms. Mean sufficiency of information score was 6.9. Topics that women most reported they did not receive sufficient information on included, what to expect during delivery (32.3%) and how their spouse/partner might support them during labor (40.3%). History of depression (β = -0.35, p = 0.03), current depressive symptoms (β = -0.66, p = 0.001), military sexual trauma (β = 0.37, p = 0.03), and experience of violence (β = 0.66, p = 0.03) were associated with lower sufficiency of information scores. Conclusion: Results indicate need for enhanced and tailored provision of information for Veterans during pregnancy, particularly among those with experience of trauma, past depression diagnoses, and current depressive symptoms. This may include optimizing care coordination and increasing access to childbirth education classes and doula support.

Prenatal maternal posttraumatic stress disorder as a risk factor for adverse birth weight and gestational age outcomes: A systematic review and meta-analysis

BACKGROUND

Although not routinely assessed, prenatal posttraumatic stress disorder (PTSD) is associated with poor maternal mental health and mother-infant bonding. Prenatal PTSD may also be associated with birth weight and gestational age outcomes, but this remains unclear. This systematic review and meta-analysis investigated the association of prenatal PTSD with risk of low birth weight (LBW) or preterm birth (PTB) (dichotomous medically-defined cut-offs) or with birth weight (BW) or gestational age (GA) (continuous variables).

METHODS

A comprehensive literature search was conducted in Web of Science, MedLine, PubMed, and PsychInfo. Data were collected and processed according to Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. Study quality was assessed with the Newcastle-Ottowa Quality Assessment Scale. Pooled effect sizes were estimated with random-effects models (correlation for continuous and odds ratios for dichotomous outcomes).

RESULTS

Sixteen studies with 51,470 participants (prenatal PTSD 8%) were included in 4 meta-analyses. Maternal prenatal PTSD was associated with higher risks of LBW (OR = 1.96; 95% CI, 1.26, 3.03; P = .003), PTB (OR = 1.42; 95% CI, 1.16, 1.73; P = .001), and reduced GA (r = -0.04; 95% CI, -0.06, -0.01; P = .002).

LIMITATIONS

Different designs across studies, variety of PTSD assessment practices, and a small pool of studies were noted.

CONCLUSIONS

Findings suggest prenatal PTSD presents increased risks of LBW, PTB, and reduced GA. Evidence of physical harm to neonates from prenatal PTSD provides a powerful rationale to increase prenatal PTSD screening and identify effective prenatal interventions to improve maternal and child outcomes.

A Scoping Review of Pregnancy, Childbirth, and the Postpartum Period in Active Duty U.S. Military Women

PURPOSE

Women in the U.S. military encounter unique challenges during the perinatal period that are driven by military requirements for mission readiness. The purpose of this scoping review was to systematically examine the extent, range, and nature of the literature on pregnancy, childbirth, and the postpartum period of active duty military women. A secondary aim was to identify leverage points for changes to improve perinatal health of servicewomen.

METHODS

We used a PRISMA-ScR protocol to guide this scoping review of research and non-research articles germane to the perinatal health of servicewomen. In the protocol, we identified the rationale, objectives, eligibility criteria, search strategy, sources of evidence, and data charting processes for the review. We used the social ecological model for military women's health framework to guide the synthesis of results.

FINDINGS

Eighty-four articles on the topics of pregnancy, childbirth, and the postpartum period of servicewomen published from 2000 to 2018 were identified. The articles were mainly research studies (n = 76), of which 49 had observational designs. Leverage points to promote workplace safety and support of pregnant women, perinatal screening, recognition of pregnancy and postpartum depression, and maintaining physical fitness during pregnancy and the postpartum period were identified in multiple levels of the social ecological model for military women's health.

CONCLUSIONS

Literature published from 2000 to 2018 is broad in scope, yet generally lacks a robust body of evidence on any one topic. Implementing strategies and military policies that are directed at the identified leverage points could enhance the health of childbearing servicewomen.

The impact of disasters on contraception in OECD member countries: a scoping review

OBJECTIVES

Review evidence is lacking about how contraception is affected by severe social disruption, such as that caused by the COVID-19 pandemic. The purpose of this scoping review was to explore the impact of natural and man-made disasters on contraception in OECD member countries.

METHODS

Manual searches and systematic searches in six electronic databases were conducted with no language restrictions. All articles were screened by at least two researchers. The data were analysed thematically.

RESULTS

108 articles were included. Most focussed on the Zika virus outbreak (n = 50) and the COVID-19 pandemic (n = 28). Four key themes were identified: importance of contraception during disasters, impact of disasters on contraceptive behaviour, barriers to contraception during disasters and ways of improving use of contraception during disasters. Despite efforts to increase access to contraception including by transforming ways of delivery, barriers to use meant that unmet need persisted.

CONCLUSIONS

To prevent adverse health outcomes and reduce health costs as a result of failure to have access to contraception during disasters, there is a need to intensify efforts to remove barriers to use. This should include increasing access and information on methods of contraception and their side effects (e.g., menstrual suppression) and making contraception freely available.

Posttraumatic Stress Disorder in a Cohort of Pregnant Active Duty U.S. Military Servicewomen

The present study aimed to describe the demographic and occupational characteristics, comorbidities, and psychotropic medication receipt associated with posttraumatic stress disorder (PTSD) diagnosis during pregnancy among a sample of active duty U.S. military servicewomen. Data from the U.S. Department of Defense Birth and Infant Health Research program were used to identify pregnancies in active duty servicewomen from 2007 through 2014. Demographic and occupational data were linked with electronic medical and pharmacy records to capture mental health diagnoses and medication receipt dates. Cases of PTSD were identified by the presence of ICD-9-CM Diagnostic Code 309.81 on maternal records from 1 year before the date of the last menstrual period through the end of pregnancy. Of 134,244 identified pregnancies among active duty servicewomen, 2,240 (1.7%) met the case criteria for PTSD. Women with a PTSD diagnosis compared to those without a PTSD diagnosis were more likely to be White non-Hispanic (51.3% vs. 47.4%), unmarried (33.3% vs. 28.2%), in the Army (49.6% vs. 35.8%) or Marine Corps (10.9% vs. 8.0%), in a service and supply occupation (18.2% vs. 13.6%), and to have a junior enlisted rank (56.3% vs. 50.1%) and have been previously deployed (51.2% vs. 39.6%), RRs = 1.15-1.75. Among PTSD cases, the most common mental health comorbidities were depressive disorder (60.9%), adjustment disorder (43.4%), and anxiety disorder (39.3%). During pregnancy, 44.2% of PTSD cases and 7.2% of noncases received psychotropic medications. Demographic and occupational characteristics, comorbidities, and psychotropic medication use differed substantially among PTSD cases and noncases in this large records-based study.

Obstetric Outcomes in Military Servicewomen: Emerging Knowledge, Considerations, and Gaps

The number of women in the U.S. military is dramatically increasing. Similarly, the roles of active-duty women are greatly expanding, thus exposing them to new occupational risks. Determining the impact of pregnancy outcomes for women while in the military is difficult due to changing exposures over time, difficulty in utilizing appropriate comparison groups, and the lack of prospective investigations. Despite these limitations, it was concerning that the available data suggest that servicewomen delivering within 6 months of their first deployment have an increased preterm birth risk (adjusted odds ratio [aOR]: 2.1), and those with three prior deployments have an even greater risk (aOR: 3.8). Servicewomen also have an increased risk of hypertensive disorders with a rate of 13% compared with 5% in the general obstetric population. Furthermore, depression is higher for women who deploy after childbirth and are exposed to combat when compared with those who have not deployed since the birth of their child (aOR: 2.01). Due to the importance of this issue, prospective research designs are necessary to better understand and address the unique health care needs of this population.

The Impact of Posttraumatic Stress Disorder and Moral Injury on Women Veterans' Perinatal Outcomes Following Separation From Military Service

Posttraumatic stress disorder (PTSD) has been found to lead to several adverse perinatal outcomes in the general population. Preliminary research has found that women veterans with PTSD have an increased prevalence of preterm birth, gestational diabetes, and preeclampsia. Less research has examined the role of moral injury (MI) in perinatal outcomes. This longitudinal survey study examined the impact of PTSD symptoms and MI on prospectively assessed adverse perinatal outcomes among women who became pregnant in the first 3 years after separating from U.S. military service (N = 318). The Moral Injury Events Scale was used to assess the degree to which individuals experienced distress related to transgressions of deeply held moral beliefs, and the Primary Care PTSD Screen for DSM-5 (PC-PTSD) was used to assess PTSD symptoms. Perinatal outcomes included experiencing an adverse pregnancy outcome (e.g., preterm birth, gestational diabetes), postpartum depression and/or anxiety, and perceived difficult pregnancy. Although both PTSD symptoms, adjusted odds ratio (aOR) = 1.16, 95% CI [1.00, 1.35]; and MI, aOR = 1.27, 95% CI [1.06, 1.41], emerged as significant predictors of adverse pregnancy outcomes, only PTSD symptoms were a significant predictor of postpartum depression and/or anxiety, aOR = 1.43, 95% CI [1.22, 1.68], and perception of a difficult pregnancy, β = .31, when controlling for lifetime trauma exposure, age, socioeconomic status, and ethnic/racial minority status. The results indicate that both PTSD symptoms and MI are associated with adverse perinatal outcomes, supporting the potential need to screen for both PTSD and MI during the perinatal period.

Health Care Experience Among Women Who Completed Group Prenatal Care (CenteringPregnancy) Compared to Individual Prenatal Care Within Military Treatment Facilities

This study compared TRICARE, the health care program of the United States Department of Defense Military Health System, beneficiaries in CenteringPregnancy, an enhanced prenatal care model, to women in individual prenatal care within the same military treatment facility. Maternity patient experience ratings from May 2014 to February 2016 were compiled from the TRICARE Outpatient Satisfaction Survey. Centering patients had 1.91 higher odds of being satisfied with access to care (p < .01, 95% CI = 1.2-3.1) than women in individual care. Specifically, the saw provider within 15 minutes of appointment measure found Centering patients to have 2.00 higher odds of being satisfied than women in individual care (p < .01, 95% CI = 1.2-3.3). There were no other statistically significant differences between cohorts. Qualitative responses indicate most Centering patients surveyed had good experiences, appreciated the structure and communication with others, and would recommend the program. Providers identified command/leadership support, dedicated space, and buy-in from all staff as important factors for successful implementation. Enhanced prenatal care models may improve access to and experiences with care. Program evaluation will be important as the military health system continues to implement such programs.

Post-traumatic stress disorder and hypertensive disorders of pregnancy among military women

BACKGROUND

Women are more likely to develop post-traumatic stress disorder (PTSD) than men. Limited research exists evaluating the risk of hypertensive disorders of pregnancy (HDP) among military women with PTSD.

METHODS

We conducted a retrospective cohort study using US Department of Defense (DoD) data comprised of all active-duty women giving birth to their first, liveborn singleton infant using DoD-sponsored health insurance from 1 January 2004 to 31 December 2008 (n = 34 176). Birth hospitalisation records, maternal mental health visits, and Post-Deployment Health Assessment (PDHA) and Reassessment (PDHRA) screenings were included. The HDP outcome (yes vs no) was defined using ICD-9-CM codes in the maternal birth hospitalisation record. Women fit into one of four PTSD exposure categories (confirmed, probable, possible, none). Confirmed cases had a PTSD ICD-9-CM diagnosis code. Probable/possible cases were classified using PDHA screening items. We used multiple log-linear regression to assess PTSD (confirmed, any vs none) and the risk of HDP overall, and then explored effect modification by military service and demographic variables. We assessed the risk of HDP among deployed mothers with PTSD (confirmed, probable/possible vs none) who completed a PDHA, and explored effect modification by race/ethnicity. We also assessed risk of HDP with differing PTSD lead times.

RESULTS

Overall, PTSD was not associated with HDP except among mothers whose PTSD was diagnosed ≥1 year prior to conception (RR 1.42, 95% CI 1.06, 1.90).

CONCLUSIONS

Post-traumatic stress disorder preceding conception by at least a year appeared to confer an increased risk of HDP, but further research is needed using more thorough PTSD assessment.

Impact of Deployment on Reproductive Health in U.S. Active-Duty Servicewomen and Veterans

Reproductive-age women are a fast-growing component of active-duty military personnel who experience deployment and combat more frequently than previous service-era women Veterans. With the expansion of the number of women and their roles, the United States Departments of Defense and Veterans Affairs have prioritized development and integration of reproductive services into their health systems. Thus, understanding associations between deployments or combat exposures and short- or long-term adverse reproductive health outcomes is imperative for policy and programmatic development. Servicewomen and women Veterans may access reproductive services across civilian and military or Veteran systems and providers, increasing the need for awareness and communication regarding deployment experiences with a broad array of providers. An example is the high prevalence of military sexual trauma reported by women Veterans and the associated mental health diagnoses that may lead to a lifetime of high risk-coping behaviors that increase reproductive health risks, such as sexually transmitted infections, unintended pregnancies, and others. Care coordination models that integrate reproductive healthcare needs, especially during vulnerable times such as at the time of military separation and in the immediate postdeployment phase, may identify risk factors for early intervention with the potential to mitigate lifelong risks.
