Posttraumatic stress disorder and war-zone exposure as correlates of perceived health in female Vietnam War veterans

Association of War Zone-Related Stress With Alterations in Limbic Gray Matter Microstructure

IMPORTANCE

Military service members returning from theaters of war are at increased risk for mental illness, but despite high prevalence and substantial individual and societal burden, the underlying pathomechanisms remain largely unknown. Exposure to high levels of emotional stress in theaters of war and mild traumatic brain injury (mTBI) are presumed factors associated with risk for the development of mental disorders.

OBJECTIVE

To investigate (1) whether war zone-related stress is associated with microstructural alterations in limbic gray matter (GM) independent of mental disorders common in this population, (2) whether associations between war zone-related stress and limbic GM microstructure are modulated by a history of mTBI, and (3) whether alterations in limbic GM microstructure are associated with neuropsychological functioning.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was part of the TRACTS (Translational Research Center for TBI and Stress Disorders) study, which took place in 2010 to 2014 at the Veterans Affair Rehabilitation Research and Development TBI National Network Research Center. Participants included male veterans (aged 18-65 years) with available diffusion tensor imaging data enrolled in the TRACTS study. Data analysis was performed between December 2017 to September 2021.

EXPOSURES

The Deployment Risk and Resilience Inventory (DRRI) was used to measure exposure to war zone-related stress. The Boston Assessment of TBI-Lifetime was used to assess history of mTBI. Stroop Inhibition (Stroop-IN) and Inhibition/Switching (Stroop-IS) Total Error Scaled Scores were used to assess executive or attentional control functions.

MAIN OUTCOMES AND MEASURES

Diffusion characteristics (fractional anisotropy of tissue [FAT]) of 16 limbic and paralimbic GM regions and measures of functional outcome.

RESULTS

Among 384 male veterans recruited, 168 (mean [SD] age, 31.4 [7.4] years) were analyzed. Greater war zone-related stress was associated with lower FAT in the cingulate (DRRI-combat left: P = .002, partial r = -0.289; DRRI-combat right: P = .02, partial r = -0.216; DRRI-aftermath left: P = .004, partial r = -0.281; DRRI-aftermath right: P = .02, partial r = -0.219), orbitofrontal (DRRI-combat left medial orbitofrontal cortex: P = .02, partial r = -0.222; DRRI-combat right medial orbitofrontal cortex: P = .005, partial r = -0.256; DRRI-aftermath left medial orbitofrontal cortex: P = .02, partial r = -0.214; DRRI-aftermath right medial orbitofrontal cortex: P = .005, partial r = -0.260; DRRI-aftermath right lateral orbitofrontal cortex: P = .03, partial r = -0.196), and parahippocampal (DRRI-aftermath right: P = .03, partial r = -0.191) gyrus, as well as with higher FAT in the amygdala-hippocampus complex (DRRI-combat: P = .005, partial r = 0.254; DRRI-aftermath: P = .02, partial r = 0.223). Lower FAT in the cingulate-orbitofrontal gyri was associated with impaired response inhibition (Stroop-IS left cingulate: P < .001, partial r = -0.440; Stroop-IS right cingulate: P < .001, partial r = -0.372; Stroop-IS left medial orbitofrontal cortex: P < .001, partial r = -0.304; Stroop-IS right medial orbitofrontal cortex: P < .001, partial r = -0.340; Stroop-IN left cingulate: P < .001, partial r = -0.421; Stroop-IN right cingulate: P < .001, partial r = -0.300; Stroop-IN left medial orbitofrontal cortex: P = .01, partial r = -0.223; Stroop-IN right medial orbitofrontal cortex: P < .001, partial r = -0.343), whereas higher FAT in the mesial temporal regions was associated with improved short-term memory and processing speed (left amygdala-hippocampus complex: P < .001, partial r = -0.574; right amygdala-hippocampus complex: P < .001, partial r = 0.645; short-term memory left amygdala-hippocampus complex: P < .001, partial r = 0.570; short-term memory right amygdala-hippocampus complex: P < .001, partial r = 0.633). A history of mTBI did not modulate the association between war zone-related stress and GM diffusion.

CONCLUSIONS AND RELEVANCE

This study revealed an association between war zone-related stress and alteration of limbic GM microstructure, which was associated with cognitive functioning. These results suggest that altered limbic GM microstructure may underlie the deleterious outcomes of war zone-related stress on brain health. Military service members may benefit from early therapeutic interventions after deployment to a war zone.

Risk factors for stress among police officers: A systematic literature review

BACKGROUND

Stress is common among police personnel leading to several negative consequences.

OBJECTIVE

We performed a systematic literature review to identify risk factors for stress among police officers.

METHODS

We searched PubMed and Scopus electronic databases through to July 2018 and we conducted this review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The Newcastle-Ottawa scale was used for studies quality assessment.

RESULTS

After selection, 29 cross-sectional studies met the inclusion criteria and included in the review. The average quality of studies was low since no study was rated as having low risk of bias, three studies (10.3%) as moderate risk and 26 studies (89.7%) were rated as having high risk of bias. Stress risk factors were summarized in the following categories: demographic characteristics; job characteristics; lifestyle factors; negative coping strategies and negative personality traits.

CONCLUSIONS

Identification of stress risk factors is the first step to create and adopt the appropriate interventions to decrease stress among police personnel. The early identification of police officers at higher risk and the appropriate screening for mental health disorders is crucial to prevent disease and promote quality of life.

The relevance of psychological strength for physical and psychological well-being in trauma-exposed women

Traumatic experiences have consistently been linked to poor health and well-being, particularly in women. Psychological factors have been theorized to directly affect the reporting of physical symptoms and perceptions of general health. Posttraumatic stress disorder (PTSD) has been proposed as a major pathway through which trauma affects health and emotion dysregulation. Trauma is considered to be a key psychological variable in the pathogenesis of PTSD. Fortunately, not all women who have experienced trauma manifest adverse effects. Resilience acts as a psychological protective variable following trauma. The present study tested a hypothetical model of the contribution of resilience, emotional dysregulation, and PTSD symptoms to physical and psychological well-being in a large sample of trauma-exposed women. A transversal study with 753 female participants is used. Structural modeling was used to test linear associations between variables. After experiencing trauma, resilience was negatively and significantly associated with emotional dysregulation, which, in turn, was positively associated with PTSD symptoms. Both resilience and PTSD symptoms were associated with physical and psychological well-being. The results suggest that resilience and emotional dysregulation are relevant to the health and well-being of women with PTSD symptoms and may help guide the development of psychological treatment in this group. Therefore, these findings may be relevant in promoting health and well-being in such women, and may help to identify individuals who would receive the most benefit from interventions addressing emotional regulation and psychological resilience.

Post-traumatic Stress Disorder Among Health Care Providers Two Years Following the Israeli Attacks Against Gaza Strip in August 2014: Another Call for Policy Intervention

• We assessed the level of PTSD among 244 doctors & nurses after two years after the 2014 war against Gaza Strip. • Results showed a high level of PTSD among 89.3% of participants two years after the war. • Female health care providers and nurses participants have higher level of PTSD. • Highest level of PTSD subscales was Intrusion followed by Avoidance and Hyper-arousal. • Intervention programs to reduce stress and trauma among participants are recommended.

Posttraumatic Stress Disorder and Somatic Complaints in a Deployed Cohort of Georgian Military Personnel: Mediating Effect of Depression and Anxiety

Several studies have shown the relationship between symptoms of posttraumatic stress disorder (PTSD), somatic symptoms, and the mediating effect of depression and anxiety. The following study was conducted to investigate the relationship between PTSD symptoms and somatic complaints through underlying symptoms of depression and anxiety. The participants of the study were 2,799 veterans who were examined after a 6-month deployment. They were assessed using the PTSD Checklist (PCL-5) and Patient Health Questionnaire (PHQ) for depression, anxiety, and somatic complaints. To check the indirect effect of PTSD on somatic complaints through depression and anxiety, mediation model 4 (parallel mediation) of the SPSS PROCESS macro was used. There was a significant total indirect effect of PTSD through depression and anxiety on somatic complaints, b = 0.14, 95% confidence interval (CI) [0.12, 0.16], from which an indirect effect of PTSD on somatic complaints through depression was b = 0.08, 95% CI [0.06, 0.10], and through anxiety it equaled b = 0.06, 95% CI [0.04, 0.07]. The ratio of indirect to total effect was 0.66, 95% CI [0.59, 0.75]. The present study helps us to understand the role of depression and anxiety symptoms when the symptoms of PTSD and somatic complaints are present. These new findings may have implications for the management as well as treatment of PTSD because they recognize the importance of symptoms of anxiety and depression when somatic complaints are present.

Pathways Between Combat Stress and Physical Health Among Portuguese War Veterans

In this study, I explored the experience of both physical and psychological chronic illnesses among a sample of Portuguese war veterans. Twenty suffered from chronic posttraumatic stress disorder (PTSD; unrecovered) and 20 had remission from PTSD (recovered), and all participants suffered from a chronic physician-diagnosed medical disorder. Two semistructured interviews were conducted. Analysis of the interviews was conducted using the Thematic and Categorical Analysis. Unrecovered participants reported higher moral injury, discrepancy between pre- and postwar identity, medication side effects, and lower repertoire of coping strategies, and verbalized that treatment care plan triggers posttraumatic symptoms. Recovered participants reported stronger moral repair, sense of continuity between pre- and postwar identity, and wider repertoire of coping strategies, well-being. Veterans' adjustment to chronic physician-diagnosed medical disorders is related to the accommodation of war traumatic experiences within existing self-schemas to restore a sense of continuity between veterans' pre- and postwar identity.

The many wounds of war: The association of service-related and clinical characteristics with problems with the law in Iraq and Afghanistan veterans

Previous research has demonstrated that veterans with posttraumatic stress disorder (PTSD) are at higher risk for aggression, hostility, and anger, potentially leading to problems with the law or disciplinary action while in the military. There have been calls for increased consideration of the unique aspects of the judicial system in legal matters with veterans involved. The bulk of the research so far has considered the link between PTSD, traumatic brain injury (TBI), and combat exposure, but little is known about the potential role of chronic pain and Military Sexual Trauma (MST) in a veteran's experience of anger, aggression, and discipline while in the military and legal concerns. The present study used retrospective cross-sectional health screening data in a sample of 1250 Iraq and Afghanistan veterans to examine the associations of demographic, service-related, and clinical characteristics with self-reported legal problems. A total of 440 veterans (34.6%) endorsed having experienced some type of problems with the law. Independent logistic regression analyses demonstrated that those who screened positive for PTSD, MST, TBI, and clinical levels of pain were more likely to report legal problems; only the associations with positive PTSD (p=0.001) and MST (p=0.007) screens remained significant in multivariate regression analyses. The findings underscore the need for a thorough psychological evaluation when veterans are involved in the legal system with a special emphasis on factors prevalent to Iraq and Afghanistan veterans.

Rates and consequences of posttraumatic distress among American Indian adults with type 2 diabetes

This study examined the prevalence of screened posttraumatic stress disorder (PTSD) and associated diabetes-related outcomes. A sample of American Indian adults with type 2 diabetes (n = 218) participated in interviewer-administered surveys. Using a cutoff of 3 on the Primary Care PTSD screener, 21.8 % of participants screened positive for PTSD. PTSD symptoms were negatively associated with self-rated health status and positively associated with past year hospitalization after controlling for several demographic factors, but not after controlling for depressive symptoms. Past month frequency of hyperglycemia symptoms was not related to PTSD symptoms. When grouped by mental health conditions (neither screened PTSD nor depressive symptoms, screened PTSD only, depressive symptoms only, and both), those with both screened PTSD and depressive symptoms reported the highest proportion of any past month hyperglycemia, past year hospitalization, and low self-rated health status. Screened PTSD, especially in those with comorbid depressive symptoms, is an important consideration in diabetes care.

Post-Traumatic Stress Disorder Among Health Care Providers Following the Israeli Attacks Against Gaza Strip in 2014: A Call for Immediate Policy Actions

PURPOSE

This study aimed to assess the level of posttraumatic stress disorder and to examine the relationship between exposure to war stress and posttraumatic symptoms among health care providers following Israeli offensives against Gaza Strip in 2014.

METHODOLOGY

A cross-sectional design was used for this study. We targeted all nurses and doctors working in three governmental hospitals in the Gaza Strip and worked with victims of the last war, more specifically, those who were working in emergency departments, intensive care units, operating rooms, surgical departments, and burn units. A demographic sheet and Impact Event Scale-Revised were used in this study. The Impact Event Scale-Revised has three sub-scales; intrusion, avoidance, and hyper-arousal.

RESULTS

The results showed that 291 (89.8%) of 324 participants had scores more than 35 (threshold cut-off point) on the Impact Event Scale-Revised. Scores ranged from zero to 80 with a mean of 52.13. Females had higher levels of stress (55.79) than males (51.63) and nurses (54.85) had more stress than physicians (47.38). The most frequent symptoms of trauma subscales was "avoidance" (mean=20.04), followed by "intrusion" (mean=17.83), and then "hyper-arousal" (mean=14.27). Levels of trauma symptoms were not affected by place of living, hospital of work, while level of education had impacted level of trauma.

CONCLUSION

The findings showed that health care providers suffered from severe posttraumatic symptoms after exposure to prolonged war stress. This level of trauma among health care providers warrants intervention programs to reduce stress and trauma among Gaza health care providers after the war.

Post-traumatic stress disorder and occupational characteristics of police officers in Republic of Korea: a cross-sectional study

OBJECTIVE

South Korean police officers have a greater workload compared to their counterparts in advanced countries. However, few studies have evaluated the occupational challenges that South Korean police officers face. Therefore, this study aimed to evaluate the police officer's job characteristics and risk of post-traumatic stress disorder (PTSD) among South Korean police officers.

DESIGN

Cross-sectional study.

SETTING

Police officers in South Korea.

PARTICIPANTS

3817 police officers with a traumatic event over a 1-year period.

MAIN OUTCOME MEASURES

Officers with a response to the Impact of Event Scale (revised Korean version) score of ≥ 26 were classified as high risk, and we evaluated their age, sex, department and rank, as well as the frequency and type of traumatic events that they experienced.

RESULTS

Among the respondents, 41.11% were classified as having a high risk of PTSD. From the perspective of the rank, Inspector group (46.0%) and Assistant Inspector group (42.7%) show the highest frequencies of PTSD. From the perspective of their working division, Intelligence and National Security Division (43.6%) show the highest frequency, followed by the Police Precinct (43.5%) and the Traffic Affairs Management Department (43.3%). It is shown that working in different departments was associated with the prevalence of PTSD (p=0.004).

CONCLUSIONS

The high-risk classification was observed in 41.11% of all officers who had experienced traumatic events, and this frequency is greater than that for other specialised occupations (eg, firefighters). Therefore, we conclude that groups with an elevated proportion of high-risk respondents should be a priority for PTSD treatment, which may help increase its therapeutic effect and improve the awareness of PTSD among South Korean police officers.

How Do Aftermath of Battle Experiences Affect Returning OEF/OIF Veterans?

Aftermath of battle experiences (ABE) may contribute to adverse mental and physical health outcomes. This study examined ABE and their effect on health functioning and posttraumatic stress disorder (PTSD) in 66 OEF/OIF/OND Veterans. Bivariate correlations were conducted to investigate the contribution of ABE to PTSD and health functioning, after controlling for combat experiences. Additionally, a mediation analyses was conducted on Role Limitations due to Emotional Problems. Results suggested that the association between ABE and Role Limitations due to Emotional Problems was mediated by PTSD. These initials findings suggest the need for more research on differences in deployment experiences.

Longitudinal study of the impact of psychological distress symptoms on new-onset upper gastrointestinal symptoms in World Trade Center responders

OBJECTIVES

Research on the health of workers involved in the cleanup after the attack on the World Trade Center (WTC) on September 11, 2001, has documented high rates of psychological distress and upper gastrointestinal (GI) symptoms. The current article examines the concurrent and longitudinal associations of psychological distress with development of new-onset upper GI symptoms in a large sample of WTC responders.

METHODS

A cohort of 10,953 WTC responders monitored by the WTC Health Program participated in the study. Two occupational groups were examined, police and nontraditional responders. The cohort was free of upper GI symptoms or diagnoses at their first visit (3 years after September 11, 2001). Logistic regression was used to analyze the relationships between concurrent and preceding psychological distress symptoms of depression, generalized anxiety, panic, and probable posttraumatic stress disorder with the development of new-onset upper GI symptoms at 3-year follow-up (6 years after September 11, 2001).

RESULTS

Across both occupation groups, psychological distress symptoms at Visit 1 were significantly related to the development of GI symptoms by Visit 2 (odd ratios ranging from 1.9 to 5.4). The results for the concurrent relationships were similar. In addition, there were significant dose-response relationships between the number of co-occurring psychological distress symptoms at Visits 1 and 2, and increased new-onset upper GI symptoms at Visit 2.

CONCLUSIONS

In this large sample of WTC responders, psychological distress symptoms assessed at 3 years after 9/11 are related to reporting upper GI symptoms 6 years after 9/11.

HealthViEWS: mortality study of female US Vietnam era veterans, 1965-2010

We conducted a retrospective study among 4,734 women who served in the US military in Vietnam (Vietnam cohort), 2,062 women who served in countries near Vietnam (near-Vietnam cohort), and 5,313 nondeployed US military women (US cohort) to evaluate the associations of mortality outcomes with Vietnam War service. Veterans were identified from military records and followed for 40 years through December 31, 2010. Information on underlying causes of death was obtained from death certificates and the National Death Index. Based on 2,743 deaths, all 3 veteran cohorts had lower mortality risk from all causes combined and from several major causes, such as diabetes mellitus, heart disease, chronic obstructive pulmonary disease, and nervous system disease relative to comparable US women. However, excess deaths from motor vehicle accidents were observed in the Vietnam cohort (standardized mortality ratio = 3.67, 95% confidence interval (CI): 2.30, 5.56) and in the US cohort (standardized mortality ratio = 1.91, 95% CI: 1.02, 3.27). More than two-thirds of women in the study were military nurses. Nurses in the Vietnam cohort had a 2-fold higher risk of pancreatic cancer death (adjusted relative risk = 2.07, 95% CI: 1.00, 4.25) and an almost 5-fold higher risk of brain cancer death compared with nurses in the US cohort (adjusted relative risk = 4.61, 95% CI: 1.27, 16.83). Findings of all-cause and motor vehicle accident deaths among female Vietnam veterans were consistent with patterns of postwar mortality risk among other war veterans.

A randomized controlled dismantling trial of post-workshop consultation strategies to increase effectiveness and fidelity to an evidence-based psychotherapy for Posttraumatic Stress Disorder

Background

Posttraumatic Stress Disorder (PTSD) is a serious mental health condition with substantial costs to individuals and society. Among military veterans, the lifetime prevalence of PTSD has been estimated to be as high as 20%. Numerous research studies have demonstrated that short-term cognitive-behavioral psychotherapies, such as Cognitive Processing Therapy (CPT), lead to substantial and sustained improvements in PTSD symptoms. Despite known benefits, only a minority of clinicians provide these therapies. Transferring this research knowledge into clinical settings remains one of the largest hurdles to improving the health of veterans with PTSD. Attending a workshop alone is insufficient to promote adequate knowledge transfer and sustained skill; however, relatively little research has been conducted to identify effective post-training support strategies.

Methods

The current study investigates whether clinicians receiving post-workshop support (six-month duration) will deliver CPT with greater fidelity (i.e., psychotherapy adherence and competence) and have improved patient outcomes compared with clinicians receiving no formal post-workshop support. The study conditions are: technology-enhanced group tele-consultation; standard group tele-consultation; and fidelity assessment with no consultation. The primary outcome is independent assessment (via audio-recordings) of the clinicians’ adherence and competence in delivering CPT. The secondary outcome is observed changes in patient symptoms during and following treatment as a function of clinician fidelity. Post-consultation interviews with clinicians will help identify facilitators and barriers to psychotherapy skill acquisition. The study results will inform how best to implement and transfer evidence-based psychotherapy (e.g., CPT) to clinical settings to attain comparable outcomes to those observed in research settings.

Discussion

Findings will deepen our understanding of how much and what type of support is needed following a workshop to help clinicians become proficient in delivering a new protocol. Several influences on clinician learning and patient outcomes will be discussed. An evidence-based model of clinical consultation will be developed, with the ultimate goal of informing policy and influencing best practice in clinical consultation.

Posttraumatic stress symptomatology as a mediator of the relationship between warzone exposure and physical health symptoms in men and women

The mediating role of posttraumatic stress symptomatology (PSS) on the association between warzone exposure and physical health symptoms in 7 bodily systems (cardiovascular, dermatological, gastrointestinal, genitourinary, musculoskeletal, neurological, and pulmonary) was examined. We also examined if mediation effects varied as a function of sex. A sample of 317 U.S. Gulf war veterans was assessed for warzone exposure, PSS, and physical health symptoms 10 years after deployment. PSS was significantly associated with postdeployment physical health in all symptom categories when accounting for predeployment health (with effect sizes ranging from a 1.27-1.64 increase in the likelihood of postdeployment physical health symptoms with a 1 standard deviation increase in the PSS symptoms). PSS severity mediated the relationship between warzone exposure and postdeployment symptoms in all physical health domains (with percent mediation ranging 44%-75%). A significant Warzone Exposure × PSS interaction emerged for 5 outcomes such that the effect of PSS on physical health was stronger for veterans reporting lower warzone exposure. No significant interactions with sex emerged. These findings suggest the important influence of PSS on physical health symptoms for both men and women.

Similarities in specific physical health disorder prevalence among formerly deployed Canadian forces veterans with full and subsyndromal PTSD

BACKGROUND

The link between posttraumatic stress disorder (PTSD) and deleterious physical health consequences among previously deployed military veterans has been well documented. Research has focused primarily on investigating prevalence rates of physical health disorders among individuals with PTSD. Far less research has compared prevalence rates of specific physical health disorders among individuals with full and subsyndromal PTSD. The current study investigated differences in the prevalence of seven specific categories of physical health disorders (i.e. musculoskeletal, circulatory, endocrine, respiratory, gastrointestinal, neurological, and other physical health disorders) among individuals with full PTSD, subsyndromal PTSD, and no PTSD (i.e. controls).

METHODS

Participants were from a sample of Canadian Forces Veteran's Affairs clients (n = 990; 96.7% men) who were previously deployed to an overseas combat theatre.

RESULTS

Logistic regressions indicated four categories of physical health conditions (musculoskeletal, neurological, gastrointestinal, and other physical health disorders) were more likely to be present among those with full PTSD compared to those in the control group. Further, five physical health disorder categories (musculoskeletal, neurological, respiratory, gastrointestinal, and other physical health disorders) were more likely to be present among those with subsyndromal PTSD when compared to those in the control group. There were no observed significant differences between full and subsyndromal PTSD.

CONCLUSIONS

Current results suggest similar patterns of specific physical health disorder prevalence among those with full and subsyndromal PTSD, which differ consistently from patterns of specific physical health disorders among those in the control group. Comprehensive results, implications, and directions for future research will be discussed.

Women Vietnam Veterans: Do PTSD Symptoms Mediate Effects of Warzone Service on Health?

We assessed the impact of warzone stress on the physical and mental health functioning and well-being of 975 female nurse veterans who had been deployed to Vietnam, and examined whether PTSD symptoms at the time of the survey mediated these relations. A questionnaire was mailed to the Women's Vietnam Memorial Project members, approximately 25 - 30 years after their wartime service. We examined current physical and mental health functioning in relation to several measures of warzone stress and PTSD symptoms, adjusting for age, length of military service, and current physical health problems. Using regression models, we evaluated whether current PTSD symptoms mediated the effects of warzone stress on mental and physical health. Findings suggested that PTSD symptoms did mediate the relationship between warzone stress and mental, but not physical, health functioning in later life. These findings suggest that among women nurses deployed to Vietnam, the effects of warzone stress many years earlier on current functioning and well-being are both direct and indirect, mediated by PTSD symptoms. The legacy of wartime deployment remains, although muted in its expression, in military nurses nearly 30 years after their return.

Health indicators for military, veteran, and civilian women

BACKGROUND

Women who have served in the military are a rapidly growing population. No previous studies have compared directly their health status to that of civilians.

PURPOSE

To provide estimates of several leading U.S. health indicators by military service status among women.

METHODS

Data were obtained from the 2010 Behavioral Risk Factor Surveillance Survey, a U.S. population-based study. Health outcomes were compared by military status using multivariable logistic regression among the female participants (274,399 civilians, 4221 veterans, 661 active duty, and 995 National Guard or Reserves [NG/R]). Data were analyzed in August 2011.

RESULTS

Veterans reported poorer general health and greater incidence of health risk behaviors, mental health conditions, and chronic health conditions than civilian women. Active duty women reported better access to health care, better physical health, less engagement in health risk behaviors, and greater likelihood of having had a recent Pap than civilian women. Women from the NG/R were comparable to civilians across most health domains, although they had a greater likelihood of being overweight or obese and reporting a depressive and anxiety disorder.

CONCLUSIONS

Compared with civilian women, NG/R women rated their health and access to health care similarly and active duty women rated theirs better on several domains, but veterans consistently reported poorer health.

Gender differences in health service utilization among Iraq and Afghanistan veterans with posttraumatic stress disorder

BACKGROUND

Little is known about gender differences in healthcare use among newly returning veterans with posttraumatic stress disorder (PTSD). We investigated gender differences in Veterans Affairs (VA) medical center health service use among Iraq and Afghanistan veterans with PTSD with and without comorbid depression and alcohol use disorders (AUD).

METHODS

Using VA administrative data, bivariate and multivariate statistics were used to examine gender differences in health service use among 159,705 Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans with PTSD seeking VA healthcare from October 7, 2001, to December 31, 2010.

RESULTS

Female veterans with PTSD were more likely to be black and single and to have higher mental health, primary care, and emergency care use compared to men with PTSD. Men were more likely to have higher mental health inpatient use compared to women. Women and men with comorbid PTSD and depression or comorbid PTSD and AUD were more likely to have higher use in all domains compared to their counterparts with PTSD without these comorbid disorders. Women with comorbid PTSD and depression were 12.5 times more likely to have a mental health inpatient hospitalization compared to their female counterparts without depression and twice as likely to have a mental health hospitalization compared to men with comorbid PTSD and depression.

CONCLUSIONS

Women with PTSD had higher use than men in almost all areas, as did all veterans with comorbid PTSD and depression and comorbid PTSD and AUD, regardless of gender. Better understanding these health service use differences will allow for targeted evaluation and integrated treatment interventions in veterans with PTSD.

Medical care needs of returning veterans with PTSD: their other burden

BACKGROUND

There has been considerable focus on the burden of mental illness (including post-traumatic stress disorder, PTSD) in returning Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans, but little attention to the burden of medical illness in those with PTSD.

OBJECTIVES

(1) Determine whether the burden of medical illness is higher in women and men OEF/OIF veterans with PTSD than in those with No Mental Health Conditions (MHC). (2) Identify conditions common in those with PTSD.

DESIGN

Cross-sectional study using existing databases (Fiscal Year 2006-2007).

SETTING

Veterans Health Administration (VHA) patients nationally.

PATIENTS

All 90,558 OEF/OIF veterans using VHA outpatient care nationally, categorized into strata: PTSD, Stress-Related Disorders, Other MHCs, and No MHC.

MEASUREMENTS

(1) Count of medical conditions; (2) specific medical conditions (from ICD9 codes, using Agency for Health Research and Quality's Clinical Classifications software framework).

MAIN RESULTS

The median number of medical conditions for women was 7.0 versus 4.5 for those with PTSD versus No MHC (p<0.001), and for men was 5.0 versus 4.0 (p<0.001). For PTSD patients, the most frequent conditions among women were lumbosacral spine disorders, headache, and lower extremity joint disorders, and among men were lumbosacral spine disorders, lower extremity joint disorders, and hearing problems. These high frequency conditions were more common in those with PTSD than in those with No MHC.

CONCLUSIONS

Burden of medical illness is greater in women and men OEF/OIF veteran VHA users with PTSD than in those with No MHC. Health delivery systems serving them should align clinical program development with their medical care needs.

Trends of elevated PTSD risk in firefighters exposed to the World Trade Center disaster: 2001-2005

OBJECTIVES

We identified trends in the prevalence of elevated posttraumatic stress disorder (PTSD) risk as determined by the Fire Department of the City of New York (FDNY)-modified PTSD Checklist in World Trade Center (WTC)-exposed firefighters. We also examined trends in relation to WTC exposure, social support, change in recreational activities, and functional health.

METHODS

We analyzed 16,826 questionnaires from 10,074 firefighters in yearly intervals, from September 12, 2001, to September 11, 2005.

RESULTS

The prevalence of elevated PTSD risk increased over time, from 9.8% in year 1 to 10.6% in year 4 (p < 0.0001). Earliest arrival at the WTC site (odds ratio [OR] = 6.0; 95% confidence interval [CI] 4.4, 8.3), prolonged work at the site (OR = 2.0; 95% CI 1.8, 2.3), providing supervision without previous supervisory experience (OR = 4.1; 95% CI 2.8, 6.1), and retirement due to a WTC-related disability (OR=1.3; 95% CI 1.1, 1.5) were associated with ever having elevated PTSD risk. Difficulty functioning at home was strongly associated with elevated PTSD risk (ORs ranged from 17.0 [95% CI 14.5, 20.0] in year 1 to 26.7 [95% CI 20.3, 35.2] in year 3), as was difficulty functioning at work (ORs ranged from 12.1 [95% CI 10.2, 14.2] in year 1 to 23.0 [95% CI 14.6, 36.3] in year 2).

CONCLUSIONS

Elevated PTSD risk was associated with exposure to the WTC site as well as functional impairment, and remained largely unabated during the first four years of the study. Screening for elevated PTSD risk may be useful in identifying those who could benefit from interventions during long-term follow-up, as well as in the immediate aftermath of disasters.

The relationship between posttraumatic stress disorder, psychiatric comorbidity, and personality traits among patients with chronic idiopathic urticaria

BACKGROUND

Several studies have highlighted the link between posttraumatic stress disorder (PTSD) and physical illnesses. No empirical studies, however, have investigated the relationship between PTSD and chronic idiopathic urticaria (CIU). The role of personality traits in this relationship was also unknown.

OBJECTIVES

This study aimed to investigate (1) the extent to which patients with CIU fulfilled the PTSD diagnosis resulting from past traumas and (2) whether they developed psychiatric comorbidity, and (3) the relationship between CIU patients' personality traits, PTSD diagnosis, severity of CIU, and psychiatric comorbidity.

METHODS

One hundred patients with CIU and 60 patients with allergy (control) participated in the study. Patients' CIU severity was assessed. Both groups completed the Posttraumatic Stress Diagnostic Scale, the General Health Questionnaire-28, the Social Readjustment Rating Scale, the Perceived Stress Scale, and the NEO-Five Factor Inventory.

RESULTS

Thirty-four percent of patients with CIU and 18% of allergy patients met the diagnostic criteria for PTSD. Patients with CIU were 1.89 times more likely to have a current diagnosis of PTSD than the control group. Controlling for life event stress and perceived stress, significant differences were found between groups (CIU PTSD, CIU no PTSD, allergy PTSD, allergy no PTSD) in somatic problems, anxiety, and social dysfunction. Controlling for life event stress and perceived stress, regression analyses showed no significant associations between personality traits, PTSD diagnosis, and the severity of CIU. Posttraumatic stress disorder diagnosis and neuroticism were, however, associated with psychiatric comorbidity.

CONCLUSIONS

Patients with CIU have been shown to have concurrent PTSD resulting from past traumas and developed psychiatric comorbidity. Chronic idiopathic urticaria patients' comorbidity was related to the patients' PTSD diagnosis and their neurotic personality trait.

War-related exposure and psychological distress as predictors of health and sleep: a longitudinal study of Kuwaiti children

OBJECTIVES

To determine whether exposure to war-related trauma during childhood predicted posttraumatic stress, self-reported health, sleep, and obesity in adulthood, and whether psychological distress mediated the relationships.

METHODS

We assessed 151 Kuwaiti boys and girls aged 9 to 12 years in 1993 to determine their level of exposure to war-related trauma during the Iraqi occupation and Gulf war, health complaints, and psychological distress. In 2003, 120 (79%) of the initial participants reported on their posttraumatic stress, general health, body mass index (BMI), and sleep quality. We tested a structural model where exposure to war-related trauma predicted psychological distress and health complaints 2 years after the war, and posttraumatic stress, self-reported health, BMI, and sleep quality and duration 10 years later, controlling for intermediary life events. We also tested effects of exposure to war-related trauma on self-reported health and sleep factors mediated by psychological distress.

RESULTS

Results indicated a direct effect of exposure on poor sleep quality and BMI. Exposure also predicted poor sleep quality through its association with concurrent posttraumatic stress. The effect of exposure on self-reported health was mediated by health complaints and psychological distress, which included symptoms of depression, anxiety, and posttraumatic stress.

CONCLUSION

Exposure to war-related events during childhood is associated with posttraumatic stress, poor sleep quality, high BMI, and poor self-reported health in adulthood.

The physical and mental health of Australian Vietnam veterans 3 decades after the war and its relation to military service, combat, and post-traumatic stress disorder

The long-term health consequences of war service remain unclear, despite burgeoning scientific interest. A longitudinal cohort study of a random sample of Australian Vietnam veterans was designed to assess veterans' postwar physical and mental health 36 years after the war (2005-2006) and to examine its relation to Army service, combat, and post-traumatic stress disorder (PTSD) assessed 14 years previously (1990-1993). Prevalences in veterans (n = 450) were compared with those in the Australian general population. Veterans' Army service and data from the first assessments were evaluated using multivariate logistic regression prediction modeling. Veterans' general health and some health risk factors were poorer and medical consultation rates were higher than Australian population expectations. Of 67 long-term conditions, the prevalences of 47 were higher and the prevalences of 4 were lower when compared with population expectations. Half of all veterans took some form of medication for mental well-being. The prevalence of psychiatric diagnoses exceeded Australian population expectations. Military and war service characteristics and age were the most frequent predictors of physical health endpoints, while PTSD was most strongly associated with psychiatric diagnoses. Draftees had better physical health than regular enlistees but no better mental health. Army service and war-related PTSD are associated with risk of illness in later life among Australian Vietnam veterans.

Pathways linking intimate partner violence and posttraumatic disorder

Intimate partner violence (IPV), which includes physical violence, sexual violence, and psychological or emotional abuse, is a significant public health threat. The Centers for Disease Control and Prevention (CDC) estimate that each year 1.5 million women are physically assaulted and/or raped by an intimate partner. However, because many victims of IPV are repeatedly abused, a more accurate accounting of the extent of violence suggests that approximately 4.8 million intimate partner physical assaults and rapes are perpetrated annually against women in the United States. The article discusses a survey involving 3,429 English-speaking women enrolled in a health maintenance organization (HMO) for 3 or more years. The findings are 46% of participants who were screened reported a lifetime history of any IPV and 14.7% reported a history within the past 5 years, including physical, sexual, and nonphysical types.

Post-traumatic stress disorder and health problems among medically ill Canadian peacekeeping veterans

OBJECTIVE

The aim of the present study was to examine the relationship between post-traumatic stress disorder (PTSD) symptom severity and four significant health conditions (gastrointestinal disorders, musculoskeletal problems, headaches, and cardiovascular problems).

METHOD

Participants included 707 Canadian peacekeeping veterans with service-related disabilities, from a random, national Canadian survey, who had been deployed overseas.

RESULTS

PTSD severity was significantly related to gastrointestinal disorders, musculoskeletal problems, and headaches, but not to cardiovascular problems. Controlling for demographic factors did not affect PTSD's relationships with the three significant health conditions.

CONCLUSIONS

The present study supports previous work in finding consistent relations between PTSD severity and specific types of medical problems.

Trajectories of self-rated health among veterans: a latent growth curve analysis of the impact of posttraumatic symptoms

OBJECTIVES

To examine the effects of combat stress reaction (CSR) and posttraumatic stress symptoms (PTS) on the level and trajectories of self-rated health (SRH) over 20 years after war exposure.

METHODS

A total of 675 veterans comprising two groups, a CSR group (n = 369) and a matched control group without CSR (n = 306), were assessed in a prospective longitudinal design, 1, 2, 3, and 20 years after their participation in the 1982 Lebanon War. SRH and PTS were assessed repeatedly, at each point of measurement.

RESULTS

The CSR participants showed more impaired initial SRH than the controls. Although the CSR group showed an improvement in SRH over time, its SRH level remained lower than that of the control group in all 4 points in time. Initial levels of PTS were associated with more impaired SRH and lower improvement over time. In addition, increased levels of PTS in the first follow-up period were related to poorer SRH, in comparison to the predicted trajectory on the basis of CSR and initial PTS.

CONCLUSIONS

Stress reaction to war trauma affected the trajectory of SRH over a 20-year period. Although the differences between veterans who had shown acute stress reaction and those who had not persisted over the entire period, there was slow improvement in SRH over time among the more impaired CSR group. PTS in the first years after the war slowed this improvement and thus played a key role in the relationship between war trauma and physical health.

Posttraumatic stress disorder and depression negatively impact general health status after hand injury

PURPOSE

To estimate the prevalence of posttraumatic stress disorder (PTSD) and depression among hand-injured patients and assess the impact of these disorders on general health status.

METHODS

A total of 106 adult hand-injured patients (40 women, 66 men) with a mean age of 42 years (range, 18-79 years) participated. Patients with a chronic mental illness or cognitive impairment were excluded. Psychological status was assessed using the Revised Civilian Mississippi Scale for PTSD and the Beck Depression Inventory. General health status was evaluated with the Short Form-36 health survey (SF-36). We obtained demographics and injury characteristics from the patient medical records.

RESULTS

Prominent mechanisms of injury included a fall (n = 38), traffic-related injuries (n = 14), machine versus operator (n = 8), gunshot wounds (n = 6), and assault (n = 6). Using the screening questionnaires, 32 persons qualified for PTSD and 19 for depression. Sixteen patients met the criteria for both PTSD and depression. The association between PTSD and depression was significant (p < .01). Patients with PTSD had significantly lower scores than those who did not endorse items consistent with PTSD or depression on the SF-36 subscales of role-emotional (p < .01), body pain (p = .013), social function (p = .028), and mental health (p < .01). We found no significant differences between groups for the subscales of role-physical (p = .289), general health (p = .147), vitality (p = .496), and physical functioning (p = .476). Patients who had concurrent PTSD and depression had significantly lower scores than patients who had neither PTSD nor depression on all subscales (p < .05 for all) except role-physical (p = .135). We found significant negative correlations between Beck Depression Inventory scores and all of the SF-36 subscales (p < .05 for all).

CONCLUSIONS

In this study, nearly one third of hand-injured patients met diagnostic criteria for PTSD, depression, or both, according to the thresholds of the instruments used to measure these psychological aspects of illness. PTSD and depression had a negative effect on general health status after hand injury. It may be important to consider psychological status when caring for patients with hand injuries.

Sexual harassment in the Marines, posttraumatic stress symptoms, and perceived health: evidence for sex differences

Sex differences and pretrauma functioning have been understudied in examinations of posttraumatic stress symptoms (PSS) and health. This study examined relationships between sexual harassment and assault in the military (MST), PSS, and perceived physical health when accounting for pre-MST PSS, pre-MST health, and current depression. Relationships were examined separately in 226 female and 91 male Marines endorsing recent MST (past 6 months). MST predicted increased PSS for women and especially men. For men, higher levels of MST were associated with worse perceived physical health, whereas for women, lower levels of MST were associated with worse perceived health. For men with MST, there was some evidence for the association being partially mediated by PSS, but no mediation was found in women.

Deployment stressors of the Iraq War: insights from the mainstream media

A comprehensive understanding of the stressors of the Iraq War is needed to ensure appropriate postdeployment assessments and to inform empirical inquiries. Yet we are unaware of any published studies that address the range of stressors experienced by this cohort. Thus, in the present study, we report the results of an interpretive literature review of mainstream media reports published from the beginning of the Iraq War in March 2003 to March 2005. This literature revealed a combination of stressors associated with traditional combat, insurgency warfare, and peacekeeping operations. The increasing deployment of National Guard/Reservist personnel, older soldiers, and women highlights additional stressors associated with sexual harassment and assault, preparedness and training, and life and family disruptions. This is a cause for concern as war-zone stressors have been implicated in postdeployment health outcomes, including intimate partner violence and child maltreatment, immediate physical and mental health, and long-term adjustment.

Posttraumatic stress symptoms as a mediator between sexual assault and adverse health outcomes in undergraduate women

This study investigated the links between sexual assault experiences, posttraumatic stress symptoms, and adverse physical health outcomes among undergraduate women. Existing research has demonstrated that posttraumatic stress disorder mediates the relationship between trauma exposure and physical health in general, but this has yet to be tested for sexual assault specifically. Using structural equation modeling, support was found for a model in which posttraumatic stress symptom severity partially mediates the association between sexual assault severity and self-reported health outcomes. An alternative model using depression symptoms did not meet the criteria for mediation. Implications for the physical health of sexual assault survivors are discussed.

Physical health and posttraumatic stress disorder symptoms in women experiencing intimate partner violence

This correlational-predictive study addresses the associations between intimate partner violence (IPV) and physical health and posttraumatic stress disorder (PTSD) symptoms, including: 1) detailed physical health symptoms reported and health care sought by women in intimate abusive relationships, 2) relationships between physical health symptoms, IPV, and PTSD, and 3) unique predictors of physical health symptoms. An ethnically diverse sample of 157 abused women was recruited from crisis shelters and the community. The women averaged almost 34 years of age and had been in the abusive relationship for slightly more than 5 years. The women experienced physical health symptoms falling into 4 groups: neuromuscular, stress, sleep, and gynecologic symptoms. Women experiencing more severe IPV reported more physical health and PTSD symptomatology. PTSD avoidance and threats of violence or risk of homicide uniquely predicted physical health. More than 75% of the women had sought treatment from a health care professional in the previous 9 months. Implications for practice are discussed.

Evaluation of physical activity habits in patients with posttraumatic stress disorder

OBJECTIVE

In this study, we present data from a survey that aimed to assess the physical activity habits of adult Brazilian patients with Posttraumatic Stress Disorder.

METHOD

Fifty male and female patients with Posttraumatic Stress Disorder participated in this study. The mean age at onset was 37+/-12 years, and the mean time between diagnosis and follow-up was 3.6+/-4.2 years.

RESULTS

Substantial changes in physical activity habits were observed following the onset of PTSD. While more than half of the patients participated in physical activities prior to Posttraumatic Stress Disorder onset, there was a significant reduction in their participation afterwards. The justifications for stopping physical activities or sport participation were lack of time and lack of motivation.

DISCUSSION

Several studies have shown that physical exercise decreases reverts symptoms of psychiatric disorders such as depression, anxiety and social isolation. We could therefore hypothesize that patients with Posttraumatic Stress Disorder who exercise should experience the same benefits.

CONCLUSION

Our findings demonstrated that patients with Posttraumatic Stress Disorder have low levels of participation in sports or physical activities.

Does number of lifetime traumas explain the relationship between PTSD and chronic medical conditions? Answers from the National Comorbidity Survey-Replication (NCS-R)

The present study sought to extend prior research by using data from the National Comorbidity Survey-Replication (NCS-R) to examine the relationship between number of lifetime traumas, posttraumatic stress disorder (PTSD) and 15 self-reported chronic medical conditions. The goal was to determine whether the commonly found relationship between PTSD symptomatology and physical health were better explained by the number of lifetime traumas experienced. The NCS-R is a representative US household survey that assessed lifetime experience of a variety of traumas, lifetime diagnosis of PTSD and 15 chronic medical conditions (e.g. pain conditions, cardiovascular disorders, etc.). Two major findings emerged: (1) there was a graded relationship between trauma exposure, PTSD, and the majority of chronic medical conditions where individuals with PTSD had the highest likelihood of chronic medical condition and non-traumatized individuals had the lowest risk and; (2) with the exception of headaches, the relationship between PTSD and chronic medical conditions was explained by the number of lifetime traumas experienced when analyses were subset to traumatized individuals. The present study supports prior research suggesting that multiple traumas have a cumulative effect on physical health. The impact of trauma on health may be independent of PTSD symptomatology.

Identifying PTSD in primary care: comparison of the Primary Care-PTSD screen (PC-PTSD) and the General Health Questionnaire-12 (GHQ)

The aim of this study was to compare the PC-PTSD and GHQ-12 in detecting new cases of PTSD among primary care patients. Data on the PC-PTSD, GHQ-12 and psychiatric diagnoses was extracted from clinical databases for 11,230 VA primary care patients. Signal detection analyses and likelihood ratios were used to compare screens. Logistic regression analysis was used to examine the prediction of PTSD by the PC-PTSD after controlling for the GHQ. The PC-PTSD had a higher positive predictive value than the GHQ (41 percent vs. 31 percent). Combining positive results on the two screens in predicting PTSD yielded the highest likelihood ratio (LR=17.3) compared to a positive result on the PC-PTSD only (LR=8.3) or the GHQ only (LR=4.6). The PC-PTSD performed slightly better than the GHQ and provided unique information in identifying PTSD, suggesting that disorder specific screens are important to use in primary care settings.

Posttraumatic stress disorder, alcohol use, and physical health concerns

PTSD is a risk factor for alcohol problems and both in turn have been independently associated with increased health problems. However, it is unclear whether alcohol use moderates the relationship between PTSD and health. Participants were battered women (N = 336) recruited from local domestic violence shelters and non-shelter victim-assistance agencies. A 2 (PTSD diagnosis) x 3 (abstainer, infrequent/light, regular/heavy drinking) ANCOVA was conducted, with injuries and length of abuse as covariates and health concerns as the dependent variable. Main effects for PTSD and alcohol use were significant but not the interaction. Women with PTSD reported the greatest number of health concerns. Women who abstained from drinking and those who drank regularly/heavily reported more health concerns than the infrequent/light drinkers. Health concerns associated with PTSD do not appear to be due to problem drinking. In addition, infrequent/light drinking, even for women with PTSD, may be associated with fewer health concerns.

The role of cumulative sexual trauma and difficulties identifying feelings in understanding female veterans' physical health outcomes

OBJECTIVE

To examine the role of alexithymia (difficulties identifying one's emotions) in understanding the link between PTSD symptoms and negative health outcomes in sexually victimized female veterans. We hypothesized that having experienced multiple types of sexual trauma across the lifespan, experiencing greater severity of PTSD symptoms, and reporting difficulties in identifying emotions would be associated with increased negative health outcomes.

METHOD

Anonymous cross-sectional survey of a convenience sample of 456 female veterans enrolled in a VA clinic within the prior year. Data collected included demographics, lifetime trauma exposure, psychological and medical symptoms, emotion recognition problems (alexithymia), health-risk behaviors, and health care utilization.

RESULTS

A total of 57.5% of participants reported a lifetime history of sexual trauma. After controlling for sexual trauma history, PTSD symptoms, and other well-established predictors of health care utilization in the VA medical system such as pre-disposing, enabling and need-based factors, hierarchical regression analyses showed that alexithymia independently explained unique variance in participants' physical health complaints and in their odds of reporting at least one outpatient urgent care visit in the past year.

CONCLUSIONS

These data suggest that emotion recognition problems may contribute to poorer health outcomes in sexually traumatized women veterans beyond what is explained by sexual trauma exposure, health risk behaviors and PTSD. Psychological interventions that enhance emotion identification skills for women who have experienced sexual trauma could improve health perceptions and reduce need for acute health care.

Trauma, PTSD, and physical health: an epidemiological study of Australian Vietnam veterans

OBJECTIVE

This study aimed to examine the relative contributions to physical health of combat trauma exposure and posttraumatic stress disorder (PTSD), which have both been implicated separately in poorer physical health but whose unconfounded effects have not been teased out.

METHODS

Data from an epidemiological study of Australian Vietnam veterans, which used personal interviews and standardized physical and psychiatric health assessments, provided the means to assess the independent and joint effects of psychological trauma exposure and PTSD on a wide range of self-reported measures of physical health. Trauma exposure was measured by published scales of combat exposure and peritraumatic dissociation. Logistic regression modeling was used to assess the relative importance of trauma exposure and PTSD to health while controlling for a set of potential confounders including standardized psychiatric diagnoses.

RESULTS

Greater health service usage and more recent health actions were associated more strongly with PTSD, which was also associated with a range of illness conditions coded by the World Health Organization International Classification of Diseases, 9th Edition (asthma, eczema, arthritis, back and other musculoskeletal disorders, and hypertension) both before and after controlling for potential confounders. In contrast, combat exposure and peritraumatic dissociation were more weakly associated with a limited number of unconfounded physical health outcomes.

CONCLUSIONS

This study provided evidence that PTSD, rather than combat exposure and peritraumatic dissociation, is associated with a pattern of physical health outcomes that is consistent with altered inflammatory responsiveness.

Direct and indirect links between childhood maltreatment, posttraumatic stress disorder, and women's health

The authors evaluated the relationships among childhood maltreatment, sexual trauma in adulthood, posttraumatic stress disorder (PTSD), and health functioning in women. Female Veterans' Affairs (VA) primary care patients (N = 200) completed self-report measures of childhood maltreatment, adult sexual trauma, PTSD symptoms, and current health functioning. The authors used structural equation modeling to test models of the relationship among these variables. Childhood nonsexual maltreatment and adult sexual assault were positively associated with PTSD. Childhood nonsexual maltreatment (beta = -.20) and PTSD (beta = -.75) were significantly associated with poorer physical and mental health functioning. Adult sexual assault negatively affected health functioning through its association with PTSD. Thus, poor health outcomes associated with childhood maltreatment in women may be conveyed through PTSD. These findings should strengthen efforts directed at identifying and treating PTSD in female victims of childhood maltreatment with the aim of preventing or attenuating poor health outcomes.

Relationships among childhood maltreatment, PTSD, and health in female veterans in primary care

OBJECTIVE

Women with histories of childhood maltreatment (CM) have higher rates of physical health problems and greater medical utilization compared to women without abuse histories. This study examined whether current post-traumatic stress disorder (PTSD) symptoms mediate the relationship between CM and indicators of physical health and medical utilization in female veterans.

METHOD

Respondents were 221 female veterans (56% of the potential sample), who received medical care from the San Diego VA Healthcare System during a 12-month period. Respondents provided self-report information about CM, PTSD symptoms, use of pain medication, and physical symptoms and functioning. Additional information about medical utilization was extracted from respondents' medical charts. Regression-based models were conducted to test whether PTSD symptoms mediate the relationships between CM and physical symptoms and between CM and medical utilization.

RESULTS

Emotional abuse was associated with poorer role-physical functioning, increased bodily pain and greater odds of using pain medication in the past 6 months. Physical abuse was associated with poorer general health. Contrary to prediction, emotional neglect was associated with better role-physical functioning, and CM was not associated with increased healthcare utilization. PTSD was shown to mediate the relationship between emotional and physical abuse and health outcomes.

CONCLUSIONS

PTSD, or psychopathology more generally, appears to be an important factor in the negative health impact of CM. Given that several empirically supported interventions are available for PTSD, there may be physical health benefits in early identification and treatment of psychopathology related to CM.

Enhanced cortisol suppression to dexamethasone associated with Gulf War deployment

OBJECTIVE

To examine whether PTSD or post-deployment health symptoms in veterans of the first Gulf War (Operation Desert Shield/Storm) are associated with enhanced suppression of the pituitary-adrenal axis to low-dose dexamethasone (DEX).

METHOD

Plasma cortisol and lymphocyte glucocorticoid receptor (GR) number were measured at 08:00 h on two consecutive days, before and after administration of 0.5mg of DEX at 23:00 h in 42 male Gulf War veterans (14 without psychiatric illness, 16 with PTSD only, and 12 with both PTSD and MDD) and 12 healthy male veterans not deployed to the Gulf War or another war zone.

RESULTS

In the absence of group differences in basal cortisol levels or GR number, Gulf War veterans without psychiatric illness and Gulf War veterans with PTSD only had significantly greater cortisol suppression to DEX than non-deployed veterans and Gulf War veterans with both PTSD and MDD. Gulf War deployment was associated with significantly greater cortisol suppression to DEX controlling for weight, smoking status, PTSD, and MDD; PTSD was not associated with response to DEX. Among Gulf War veterans musculoskeletal symptoms were significantly associated with cortisol suppression and those who reported taking anti-nerve gas pills (i.e., pyridostigmine bromide) during the war had significantly greater DEX-induced cortisol suppression than those who did not.

CONCLUSIONS

The data demonstrate that alterations in neuroendocrine function are associated with deployment to the Gulf War and post-deployment musculoskeletal symptoms, but not PTSD. Additional studies are needed to examine the relationship of enhanced glucocorticoid responsivity to deployment exposures and chronic unexplained medical symptoms in Gulf War veterans.

Immune function in PTSD

Disturbed regulation of both the hypothalamic-pituitary-adrenal (HPA) axis and sympathoadrenomedullary system in posttraumatic stress disorder (PTSD) suggests that immune function, which is modulated by these systems, may also be dysregulated. Two dermatologic, in vivo measures of immune function, delayed-type hypersensitivity (DTH) and skin barrier function recovery, were examined in female subjects with PTSD and compared to measures in healthy female comparison subjects. In addition, at the time of DTH test placement, circulating numbers of lymphocyte subtypes were assessed. In separate studies, the effects of acute psychological stress on DTH and skin barrier function recovery were examined in healthy volunteer subjects. Both DTH and barrier function recovery were enhanced in women with PTSD. These findings contrast with the effects of acute stress in healthy control subjects, which was associated with suppression of DTH responses and skin barrier function recovery. There was no difference between subjects with PTSD and healthy control subjects in proportions of circulating lymphocyte subsets or in expression of the lymphocyte markers CD62, CD25, and CD45RO/CD45RA. These results suggest that cell-mediated immune function is enhanced in individuals with PTSD, a condition that imposes chronic physiologic and mental stress on sufferers. These findings contrast with suppression of DTH and skin barrier function recovery in healthy volunteers in response to acute psychological stress.

Psychiatric and physical health ramifications of traumatic events in women

All individuals are at some risk of experiencing a traumatic event and developing posttraumatic stress disorder (PTSD); however some individuals are at higher risk due to individual and environmental factors. This critical literature review focuses on women, as they are twice as likely as men to develop PTSD in their lifetimes. Should a woman develop PTSD, she is then at risk of developing psychiatric and physical health comorbidities that can further impact her quality of life. The strengths and limitations of current studies regarding this topic are discussed as are directions for future research and issues for nurses treating traumatized individuals.
