Military personnel's stress reactivity during pre-deployment in a war zone

Many studies have been conducted on the numerous negative post-deployment outcomes for military personnel. However, data on service members' pre-deployment stress reactivity are absent. This is a serious gap in existing research, as stress has an important regulatory role. This study aimed to determine possible manifestations of military personnel's stress reactivity during pre-deployment in a war zone in eastern Ukraine. The study involved 270 Ukrainian service members (all male, aged 18 to 58 years). Sample 1 (n = 108) were preparing to be deployed for the first time, sample 2 (n = 84) were preparing to be deployed and had previous experience of deployment, and sample 3 (n = 108) were not preparing to deploy and had no previous deployment experience. We used the Ukrainian adaptation of the Giessen Subjective Complaints List (GBB-24), the Symptom Checklist-90-Revised (SCL-90-R), the Short Screening Scale for DSM-IV posttraumatic stress disorder and the Combat Exposure Scale (CES). We found that indicators for physical complaints, psychological problems and psychopathological and posttraumatic symptoms among service members from samples 1 and 2 were significantly higher than those of sample 3 in 15 of 18 cases (p < 0.001-0.05). The indicators obtained for sample 2 were higher than those of sample 1 in six of nine cases (p < 0.001-0.05). Both our study hypotheses were confirmed. The present findings can be used to develop efficient psychological interventions for military personnel during pre-deployment in a war zone.

Do children separated from fathers have higher anxiety levels? A comparative analysis

Background

There is limited literature from India on effect of fathers' deployment on the mental health of children. This cross-sectional analytical study investigates the difference in anxiety levels of children whose fathers are deployed in a field location and compares it with children currently located with their fathers.

Method

Data were collected in an army school from 200 children aged 10-17 years with fathers deployed in field locations (n = 99) and fathers currently residing with the children (n = 105) via interviewer administered and self-completed Screen for Child Anxiety-Related Disorders (SCARED) questionnaire.

Results

Anxiety scores were on an average, minimally raised above the cut-off level for children who had fathers deployed. In addition, panic disorder scores were also above the cut-off levels for these children. While scores were normal in all other domain, they were higher than that for children residing with their fathers, although the difference was not significant. Girls with fathers deployed had scores higher than cut-off scores for domains such as panic, separation anxiety and school avoidance, while boys had scores higher than cut-off scores only for panic disorders. However, the girls had significantly higher scores than boys in all domains. Girls in both groups (with and without father deployed) had higher scores than cut-off scores for panic disorders.

Conclusion

Anxiety levels in children were not found to be unduly affected by the deployment of fathers. But girls were found to have clinically relevant panic disorder, school avoidance and separation anxiety scores as compared with boys in the similar situation of parental separation.

How Sleep Research in Extreme Environments Can Inform the Military: Advocating for a Transactional Model of Sleep Adaptation

PURPOSE OF REVIEW

We review the literature on sleep in extreme environments. Accordingly, we present a model that identifies the need for mitigating interventions to preserve sleep quality for military deployments.

RECENT FINDINGS

Situational factors that affect sleep in extreme environments include cold temperatures, isolated and confined areas, fluctuating seasonality, photoperiodicity, and extreme latitudes and altitudes. Results vary across studies, but general effects include decreased total sleep time, poor sleep efficiency, and non-specific phase delays or phase advances in sleep onset and sleep architecture. Considering habitability measures (e.g., light or temperature control) and individual differences such as variable stress responses or sleep need can mitigate these effects to improve mood, cognition, and operational performance. Although the situational demands during military missions inevitably reduce total sleep time and sleep efficiency, mitigating factors can attenuate sleep-related impairments, hence allowing for optimal mission success and personnel safety.

Examining bidirectional associations between perceived social support and psychological symptoms in the context of stressful event exposure: a prospective, longitudinal study

BACKGROUND

After stressful event exposure, higher perceived social support is a well-established correlate of decreased risk for psychological symptoms, including depressive, anxiety and posttraumatic stress (PTS) symptoms. However, longitudinal data on the direction of this association and the stability of perceived social support are scarce and have yielded mixed results, with a particular lack of prospective studies. We aimed to investigate changes in perceived social support and bidirectional associations between perceived social support and psychological symptoms in a prospective, longitudinal study.

METHODS

A sample of German soldiers was assessed before and after deployment to Afghanistan. Group-based trajectory modelling was used to investigate the stability of perceived social support and to identify possible distinguishable trajectories of perceived social support. Bidirectional associations between perceived social support (general and workplace) and psychological symptoms (depressive, anxiety and PTS) were examined using gamma regressions.

RESULTS

Average levels of perceived general social support did not change, while perceived workplace social support increased slightly (t(344) = 5.51, p < .001). There were no distinguishable trajectories of perceived social support. Higher perceived general (Mean ratio (MR) = 0.84, 95% CI = [0.74, 0.95]) and workplace social support (MR = 0.82, 95% CI = [0.72, 0.92]) predicted lower depressive symptoms, but not anxiety or PTS symptoms. Only higher PTS (MR = 0.95, 95% CI = [0.91, 0.99]) and higher depressive symptoms (MR = 0.96, 95% CI = [0.93, 0.99]) predicted lower perceived general social support.

CONCLUSIONS

Perceived social support can remain relatively stable under exposure to environmental stressors such as military deployment. Higher perceived social support could protect against depressive symptoms via a stress-buffering mechanism, while support may need to be more tailored to individual needs for a protection against PTS symptoms. Individuals with elevated depressive and PTS symptoms might have impaired abilities or opportunities to access social support after stressful event exposure. Future studies could investigate distressing social emotions and associated maladaptive social cognitions as possible mechanisms in the association between symptoms and lower perceived social support. Especially with respect to PTS symptoms, future studies could focus on conditions that enable individuals to benefit from social support.

Quantitative imaging analysis detects subtle airway abnormalities in symptomatic military deployers

Background

Exposure to inhalational hazards during post-9/11 deployment to Southwest Asia and Afghanistan puts military personnel at risk for respiratory symptoms and disease. Pulmonary function and qualitative chest high resolution computed tomography (HRCT) are often normal in “deployers” with persistent respiratory symptoms. We explored the utility of quantitative HRCT imaging markers of large and small airways abnormalities, including airway wall thickness, emphysema, and air trapping, in symptomatic deployers with clinically-confirmed lung disease compared to controls.

Methods

Chest HRCT images from 45 healthy controls and 82 symptomatic deployers with asthma, distal lung disease or both were analyzed using Thirona Lung quantification software to calculate airway wall thickness (by Pi10), emphysema (by percentage of lung volume with attenuation < -950 Hounsfield units [LAA%-950]), and three parameters of air trapping (expiratory/inspiratory total lung volume and mean lung density ratios, and LAA%-856). SAS v.9.4 was used to compare demographic and clinical characteristics between deployers and controls using Chi-Square, Fisher Exact or t-tests. Linear regression was used to assess relationships between pulmonary function and quantitative imaging findings.

Results

Gender and smoking status were not statistically significantly different between groups, but deployers were significantly younger than controls (42 vs 58 years, p < 0.0001), had higher body mass index (31 vs 28 kg/m², p = 0.01), and had fewer total smoking pack-years (8 vs. 26, p = 0.007). Spirometric measures were not statistically significantly different between groups. Pi10 and LAA%-950 were significantly elevated in deployers compared to controls in unadjusted analyses, with the emphysema measure remaining significantly higher in deployers after adjustment for age, sex, smoking, BMI, and expiratory total lung volume. Air trapping parameters were more common in control images, likely due to differences in age and smoking between groups. Among deployers, LAA%-950 and Pi10 were significantly correlated with spirometric markers of obstruction based on ratio of forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) and/or percent predicted FEV1.

Conclusions

Quantitative chest HRCT imaging analysis identifies emphysema in deployers with asthma and distal lung disease, and may be useful in detecting and monitoring deployment-related lung disease in a population where spirometry is typically normal.

Multiple breath washout: A noninvasive tool for identifying lung disease in symptomatic military deployers

RATIONALE

Military deployments to austere environments since November 9, 2001 may put "deployers" at risk for respiratory disease. Sensitive, noninvasive tools for detecting large and small airways injury are needed to identify early disease and help inform management for this at-risk population.

OBJECTIVES

We examined multiple breath washout (MBW) as a tool for identifying deployment-related airways disease and assessed host and exposure risk factors compared to healthy controls.

METHODS

Between March 2015 and March 2020, 103 healthy controls and 71 symptomatic deployers with asthma and/or distal lung disease completed a questionnaire, spirometry and MBW testing. SAS v. 9.4 was used to compare MBW parameters between deployers and controls via univariate analyses and adjusted for demographic factors using multiple linear regression.

MEASUREMENTS AND MAIN RESULTS

Deployers were significantly more likely than controls to have an abnormal lung clearance index (LCI) score indicating global ventilation inhomogeneity. Adjusting for sex, smoking status, smoking pack-years and body mass index, LCI scores were significantly more abnormal among those with deployment-related asthma and distal lung disease compared to controls. The unadjusted variable Sacin (a marker of ventilation inhomogeneity in the acinar airways) was higher and thus more abnormal in those with both proximal and distal airways disease. Deployers who reported more frequent exposure to explosive blasts had significantly higher LCI scores.

CONCLUSIONS

This study demonstrates the utility of MBW in evaluating exposure-related airways disease in symptomatic military personnel following deployment to austere environments, and is the first to link exposure to explosive blasts to measurable small airways injury.

Occupational Bronchiolitis: An Update

Occupational bronchiolitis is characterized by inflammation of the small airways, and represents a heterogeneous set of lung conditions that can occur following a range of inhalation exposures related to work. The most common clinical presentation includes insidious onset of exertional dyspnea and cough. Multiple reports in recent years have drawn attention to previously unrecognized risk factors for occupational bronchiolitis following exposures in several settings. Both current and past occupational exposures, including prior military deployment-related exposures, should be considered in patients undergoing evaluation for unexplained dyspnea. Diagnostic testing for potential bronchiolitis should include a thorough assessment of the small airways.

[Orofacial dysfunction and posttraumatic stress disorder : A context analysis of soldiers after military deployment]

BACKGROUND

In studies on posttraumatic stress disorder (PTSD, ICD 10: F43.1) and in clinical observation, the high proportion of soldiers with painful craniomandibular dysfunction (CMD) is conspicuous.

AIM

This study aimed to clarify if there is a connection between orofacial dysfunction, pain in this region, stress and PTSD.

MATERIAL AND METHODS

A total of 36 inpatients (PTSD group) with specialist psychiatrically confirmed PTSD after up to 17 foreign deployments and 36 control subjects with 2-40 foreign deployments underwent a functional dental examination. All participants filled out a form for the gradation of chronic pain (GCP, degrees 0-4) as well as the depression, fear and stress scale (DFSS).

RESULTS

Soldiers with PTSD had significantly worse orofacial functional diagnoses and higher pain scores, although on average they had less combat deployments (PTSD: maximum mouth opening 31.4 ± 8.0 mm vs. 57 ± 6 mm, GCP 3.5 ± 1.0 vs. 0.5 ± 0.5).The PTSD group showed a depression score of 14.9 ± 4.2 vs. the control group 1.4 ± 2.1, a fear score of 13.7 ± 3.9 vs. 1.0 ± 1.5 and a stress score of 16.1 ± 3.4 vs. 3.3 ± 2.9.

CONCLUSION

The data from this pilot study show an obvious connection between PTSD and orofacial dysfunctions. Through further prospective studies it should be evaluated if there is a general vulnerability of those afflicted for pathological orofacial stress. This could be used for screening before combat deployment.

Non-oncologic Indications for Male Fertility Preservation

PURPOSE OF REVIEW

To explore non-oncologic indications for male fertility preservation.

RECENT FINDINGS

Common scenarios in which male fertility could be irreversibly compromised include autoimmune conditions requiring treatment with cyclophosphamide, gender dysphoria prior to starting hormone therapy, military deployment, and critical illness. Fertility preservation should be considered with particular attention to the timing and logistics specific to each scenario. Recognition and familiarity with such situations will help physicians provide better counseling to patients and their families, improve the quality of decision-making, and ultimately reduce missed opportunities and regret.

Parental military deployment as risk factor for children's mental health: a meta-analytical review

There is evidence that military service increases the risk of psychosocial burden for not only service members but also their spouses and children. This meta-analysis aimed to systematically assess the association between military deployment of (at least one) parent and impact on children's mental health. For this meta-analytic review, publications were systematically searched and assessed for eligibility based on predefined inclusion criteria (studies between 2001 until 2017 involving children with at least one parent working in military services). Measurements were determined by total problem scores of the children as well as symptoms of anxiety/depression, hyperactivity/inattention, and aggressive behavior. Meta-analyses aggregated the effect sizes in random-effect models and were calculated separately for the relation between parental deployment and civilian/normative data and for the relation between parental deployment and non-deployment. Age of the children was used as moderator variable to explore any potential source of heterogeneity between studies. Parental military deployment was associated with problems in children and adolescents compared to civilian/normative samples. Significant effect sizes reached from small to moderate values; the largest effect sizes were found for overall problems and specifically for anxious/depressive symptoms and aggressive behavior. Within the military group, children of deployed parents showed more problem behavior than children of non-deployed parents, but effect sizes were small. Age of the children had no moderating effect. The results emphasize that children of military members, especially with a deployed parent, should be assessed for emotional and behavioral problems.

Improving Child Peer Adjustment in Military Families through Parent Training: The Mediational Role of Parental Locus of Control

The current study investigated the mechanisms through which a parenting intervention for military families fosters positive peer adjustment in children. A sample of 336 families with a history of parental deployment enrolled in a randomized controlled trial of the After Deployment Adaptive Parenting Tools (ADAPT) preventive intervention. ADAPT is a 14-week preventive intervention designed to strengthen parenting in military families. The intervention was associated with improvements in mother's and father's parental locus of control (i.e., a more internal locus of control) at a 6-month follow-up assessment while controlling for baseline levels. Mothers' parental locus of control was positively associated with improvements in children's peer adjustment 12 months following the intervention while controlling for baseline peer adjustment. A significant indirect effect revealed that participation in ADAPT resulted in improved 12-month peer adjustment by improving mothers' parental locus of control. Implications for supporting youth resilience to stressors associated with deployment are discussed.

Pre-deployment Year Mental Health Diagnoses and Treatment in Deployed Army Women

We estimated the prevalence of select mental health diagnoses (MHDX) and mental health treatment (MHT), and identified characteristics associated with MHT during the pre-deployment year (365 days before deployment) in active duty Army women (N = 14,633) who returned from Iraq or Afghanistan deployments in FY2010. Pre-deployment year prevalence estimates were: 26.2 % for any select MHDX and 18.1 % for any MHT. Army women who had physical injuries since FY2002 or any behavioral health treatment between FY2002 and the pre-deployment year had increased odds of pre-deployment year MHT. During the pre-deployment year, a substantial percentage of Army women had MHDX and at least one MHT encounter or stay. Future research should determine if pre-deployment MHDX among Army women reflect vulnerability to future MHDX, or if pre-deployment MHT results in protection from chronic symptoms.

Caring for children and youth from Canadian military families: Special considerations

Military families experience a number of life stressors, such as frequent geographical moves, long periods of separation within the family, geographic isolation from extended family support systems and deployments to high-risk areas of the world. While children and youth in military families experience all the same developmental and motivational trajectories as their civilian counterparts, they must also contend with more unusual developmental pressures and stressors placed on them by the unique demands of military life. The effects of the military life on families and children are beginning to be recognized and characterized more fully. Understanding the unique concerns of children and youth from military families and mobilizing specific resources to support them are critical for meeting the health care needs of this population.

The long-term burden of military deployment on the health care system

Health care providers need to be aware that stress complaints that result from deployment can emerge even after many years. This has important implications for health care policies. The main aim of this study is to investigate the relation between the development of posttraumatic stress and other mental health complaints and the burden on (mental) health care after a deployment. For this study we used data from a large prospective cohort study on stress-factors related to deployment in 1007 Dutch soldiers, who were deployed to Afghanistan. Participants were assessed at six follow up times up until five years after deployment. In a Generalized Estimated Equations model we estimated the relation between mental health complaints and the utilization of psychological treatment and a general practitioner, respectively. Moreover, we studied the relation between mental health complaints and health care costs using bootstrap techniques. The results showed that higher scores for PTSD, depression and fatigue relate to increased use of a psychologist. And lower PTSD scores and higher depression, anxiety and somatization scores relate to increased odds to visit a GP. Furthermore, mental health complaints relate to higher costs. In conclusion, monitoring soldiers is important in order to be informed on the current demand for (mental) health care to satisfy the health care need of veterans. Early treatment, which is enabled by lowering barriers to care, relates to positive results and therefore, lower health care costs.

Gender differences in substance use treatment utilization in the year prior to deployment in Army service members

Although military men have heavier drinking patterns, military women experience equal or higher rates of dependence symptoms and similar rates of alcohol-related problems as men at lower levels of consumption. Thus, gender may be important for understanding substance use treatment (SUT) utilization before deployment. Military health system data were analyzed to examine gender differences in both substance use diagnosis (SUDX) and SUT in 152,447 Army service members returning from deployments in FY2010. Propensity score analysis of probability of SUDX indicated that women had lower odds (AOR: 0.91, 95% CI: 0.86-0.96) of military lifetime SUDX. After adjusting for lifetime SUDX using propensity score analysis, multivariate regression found women had substantially lower odds (AOR: 0.61; 95% CI: 0.54-0.70) of using SUT the year prior to deployment. Findings suggest gender disparities in military-provided SUT and a need to consider whether military substance use assessment protocols are sensitive to gender differences.

Psychiatric effects of military deployment on children and families: the use of play therapy for assessment and treatment

Deployments in the United States military have increased greatly in the past 10 years. Families and children are psychiatrically affected by these deployments, and recent studies are clarifying these effects. This article focuses on the psychiatric effects of deployment on children and uses a composite case example to review the use of play therapy to treat children who are having psychiatric issues related to the deployment of one or both parents.
