Gender differences in disorders comorbid with posttraumatic stress disorder among U.S. Sailors and Marines

Emotional reactivity linking assaultive trauma and risky behavior: Evidence of differences between cisgender women and men

Accumulating evidence suggests that trauma exposure is positively associated with future engagement in risky behavior, such as substance misuse, aggression, risky sex, and self-harm. However, the psychological factors driving this association and their relevance across gender groups require further clarification. In a community sample of 375 adults with a high rate of trauma exposure (age range: 18-55 years, M = 32.98 years, SD = 10.64; 76.3% assaultive trauma exposure), we examined whether emotional reactivity linked lifetime assaultive trauma exposure with past-month risky behavior. We also explored whether this model differed for cisgender women (n = 178, 47.6%) and men (n = 197, 52.5%). As hypothesized, assaultive trauma was positively related to emotional reactivity, β = .20, SE = 0.03, t(369) = 3.65, p < .001, which, in turn, partially accounted for the association between assaultive trauma and past-month risky behavior, indirect effect: β = .03, SE = 0.01, 95% bootstrapped CI [0.01, 0.06]. Gender moderated this association such that assaultive trauma was indirectly associated with risky behavior via emotional reactivity for women but not for men, index moderation: B = -0.03, SE = 0.02, 95% bootstrapped CI [-0.07, -0.01]. Cross-sectional results suggest that emotional reactivity may be a proximal target for clinical intervention to aid in the reduction of risky behavior among women.

An overview of the differences in the pharmacological management of post-traumatic stress disorder between women and men

INTRODUCTION

Post-traumatic stress disorder (PTSD) is a disabling psychiatric condition with a worldwide prevalence between 6% and 9%, and more common in the female than in the male sex. The aim of this paper is to review and comment on the different factors that might explain the discrepancies in the pharmacological management of women and men.

AREAS COVERED

The available literature shows that there exists a vulnerability of women to develop PTSD that may depend on neurobiological as well as environmental/cultural factors. These variables might influence the clinical picture, the outcome and the response to specific treatments, given their consequences on the pharmacokinetics of commonly prescribed drugs. Women suffering from PTSD are more prone to consult and receive more prescriptions of psychotropic drugs than men. However, it is evident that the particular stages of a women's life such as pregnancy or breastfeeding might require a specific evaluation and care.

EXPERT OPINION

It is necessary to explore the pharmacokinetics of compounds highlighting sex-related differences, and their safety during pregnancy and lactation. Taking care of differences between women and men should represent a main focus of research, while being a primary target towards a really tailored pharmacological treatment of PTSD.

Male sex and hazardous alcohol use following military sexual assault increase suicide risk among US service members and veterans

Background: Higher alcohol use and military sexual assault (MSA) are associated with increased risk of death by suicide. Risk for death by suicide is rapidly increasing among females, who report higher rates of MSA, yet actual death by suicide and alcohol use are higher among males. It is not well understood whether higher alcohol use confers greater suicide risk in male or female service members and veterans who have experienced MSA.Objective: To determine whether the association between alcohol misuse and suicide risk was moderated by biological sex in a sample of male and female service members (N = 400, 50% female) who reported MSA.Method: Participants completed surveys of alcohol use and suicide risk as well as a demographic inventory. Linear regression with an interaction term was used to determine if suicide risk differed by sex and alcohol use severity after accounting for discharge status, sexual orientation, and age.Results: Average scores on the suicide risk measure were consistent with an inpatient psychiatric sample and scores on the AUDIT-C were indicative of a probable positive screen for alcohol misuse. Suicide risk was most pronounced among males who reported higher levels of hazardous alcohol use. A sensitivity analysis examining suicide risk by sex and screening results for alcohol misuse (positive/negative) showed that men with a probable positive screen had higher suicide risk.Discussion: The current study provides novel findings on suicide risk among survivors of military sexual violence by including both male and female survivors. Interventions to decrease suicide risk following MSA may consider alcohol reduction strategies, and optimizing these interventions in males. Engaging military culture at both the US Departments of Defense and Veterans Affairs to encourage more healthy alcohol consumption may mitigate this public health concern. Future research may consider how country of origin relates to these associations.

Traumatic stress-enhanced alcohol drinking: Sex differences and animal model perspectives

Purpose of review

Stress is associated with alcohol drinking, and epidemiological studies document the comorbidity of alcohol use disorder (AUD) and post-traumatic stress disorder (PTSD), with higher comorbid prevalence in females than in males. The aim of this paper is to highlight information related to sex differences in stress-enhanced alcohol drinking from clinical studies and from preclinical studies utilizing an animal model of traumatic stress.

Recent findings

Stress is associated with alcohol drinking and relapse in males and females, but there are sex differences in the alcohol-related adaptation of stress pathways and in the association of different prefrontal regions with stress-induced anxiety. The predator stress model of traumatic stress produced enhanced alcohol drinking in a subgroup of stress-sensitive male and female animals, which could be associated with sex and subgroup differences in stress axis responsivity, behavioral responses to predator odors, and epigenetic mechanisms engaged by traumatic experiences.

Summary

While additional studies in females are necessary, existing clinical and preclinical evidence suggests that biological mechanisms underlying stress-enhanced drinking likely differ between males and females. Thus, effective treatment strategies may differ between the sexes.

Effects of sex and gender on the etiologies and presentation of select internalizing psychopathologies

The internalizing spectrum encompasses a subset of psychopathologies characterized by emotional liability, anhedonia, anxiousness, distress, and fear, and includes, among others, diagnoses of major depressive disorder (MDD), generalized anxiety disorder (GAD), and posttraumatic stress disorder (PTSD). In this review, we describe the vast body of work highlighting a role for sex and gender in the environment, symptom onset, genetic liability, and disorder progression and comorbidities of MDD, GAD, and PTSD. We also point the reader to different language used in diverse fields to describe sexual and gender minorities that may complicate the interpretation of emerging literature from the social sciences, psychiatric and psychological sciences, and genetics. Finally, we identify several gaps in knowledge that we hope serve as launch-points for expanding the scope of psychiatric studies beyond binarized sex-stratification. Despite being under-represented in genomics studies, placing emphasis on inclusion of sexual and gender diverse participants in these works will hopefully improve our understanding of disorder etiology using genetics as one tool to inform how biology (e.g., hormone concentration) and environmental variables (e.g., exposure to traumatic events) contribute to differences in symptom onset, pattern, and long-term trajectory.

Associations between DSM-5 posttraumatic stress disorder Criterion E2 endorsement and selected self-destructive behaviors in recent-era veterans: A focus on disordered eating

Revisions to the posttraumatic stress disorder (PTSD) criteria in the DSM-5 included a new criterion in the alterations in arousal and reactivity cluster (i.e., engagement in reckless and self-destructive behaviors; Criterion E2). Despite its clinical significance, little is known about how this symptom corresponds to engagement in specific direct and indirect self-harm behaviors. We examined associations between E2 and self-reported recent engagement in direct and indirect self-harm behaviors, including disordered eating, which is not included in the prototypical E2 symptom scope, in a trauma-exposed sample of 1,010 recent-era veterans (61.5% self-identified women, 38.5% self-identified men). We also tested whether gender moderated these associations. We repeated analyses in a subsample of participants with clinically elevated PTSD symptoms. Participants self-reported past-month PTSD symptoms (PCL-5) as well as past-month nonsuicidal self-injury, suicidal ideation, suicide planning, fasting, purging, binge eating, compulsive exercise, and problematic alcohol and drug use. We found no evidence for moderation by gender for any of the behaviors examined in the main sample. However, after controlling for gender and demographic covariates, weighted logistic regressions showed small, significant associations between E2 score and direct self-harm behaviors, substance use, purging, and binge eating, aORs = 1.30-1.91. Criterion E2 was linked to behaviors included in the typical symptom scope (self-directed violence, substance use) and those that are not (disordered eating behaviors). Comprehensive screening for self-destructive behaviors, including disordered eating, among veteran men and women who endorse Criterion E2 is indicated.

A Systematic Review of Quantitative and Qualitative Results of Randomized Controlled Trials Assessing the Effect of Yoga in Adult Women With Post-traumatic Stress Disorder: What Is Known So Far

Yoga has been increasingly practiced in recent years, with many of its practitioners being female. Adults may seek a complementary and alternative medicine (CAM) modality, such as yoga, to attempt to alleviate symptoms related to mental health conditions such as post-traumatic stress disorder (PTSD). Our goal for this systematic review was to collect and analyze all available data from quantitative and qualitative reports of randomized controlled trials (RCTs) conducted over the past 10 years on the impact of yoga on women diagnosed with PTSD. We included RCTs with the adult female population in which yoga was practiced for more than one week. We searched the databases PubMed, PubMed Central (PMC), and MEDLINE on June 11, 2022, Embase on June 12, 2022, and Science Direct on June 13, 2022, to find relevant articles. With the Cochrane RoB2 tool and Critical Appraisal Skills Programme (CASP) criteria, we checked for their quality, after which we selected 13 high-quality reports comprising seven original study designs and a total of 496 women. Of the 13 reports, nine evaluated effectiveness, four assessed feasibility, three explored acceptability, and four identified qualitative themes. We compared the results based on the assessed themes. Our results found yoga effective, feasible, acceptable, and a viable interoceptive pathway for emotional and personal growth. Limitations in our study include insufficient papers with large sample sizes and not including papers other than RCTs. With our research, we hope to present healthcare providers with research-based data on the effects of yoga so that they may better navigate its role in therapy as the trend of seeing more patients taking an interest in such alternative approaches rises.

The impact of adversities across the lifespan on psychological symptom profiles in late adulthood: a latent profile analysis

People commonly face adverse circumstances throughout life, which increases risk for psychiatric disorders, such as anxiety, depression, psychosis, and posttraumatic stress disorder (PTSD). Adversities may occur during different periods in life. Especially adversity during early periods has been suggested to put individuals at risk for adverse mental health outcomes. Here, we investigated whether timing of adversity during the prenatal period, childhood, or mid-to-late adulthood differentially impacted classification into late adulthood symptom profiles. We performed sex-stratified Latent Profile Analysis to identify latent profiles regarding anxious, depressive, psychotic, and PTSD symptoms in n = 568 Dutch famine birth cohort members (n = 294 women, n = 274 men, mean age(SD) = 72.9(0.8)). Cross-sectional late adulthood symptomatology, childhood traumatic maltreatment, and adulthood trauma were based on self-report questionnaires. Prenatal adversity was considered present when individuals were prenatally exposed to the 1944-45 Dutch famine. In both men and women we identified one anxious/depressive profile and three profiles with approximately equal severity of all symptom types within each profile, yet differentiating in overall severity (low, mild, high) between profiles. We additionally found a PTSD symptom profile in women. In men, logistic regression models showed significant associations between prenatal, childhood and adulthood adversity, and profile classification, with differential effects depending on timing and most profound effects of child maltreatment. In women, childhood and adulthood adversity significantly increased classification probability into almost all profiles, with no significant effect of prenatal adversity. These findings support a time-dependent and sex-specific impact of adversity during different periods across the lifespan on psychological health, with consequences into late adulthood.

The Posttraumatic Cognitions Inventory (PTCI): Psychometric evaluation in veteran men and women with trauma exposure

The Posttraumatic Cognitions Inventory (PTCI) is a self-report measure of negative posttraumatic cognitions, which is an important construct in the development and maintenance of posttraumatic stress disorder (PTSD). Evidence for the most appropriate PTCI item and factor structure is mixed, and this measure has not been extensively studied in veterans. The present study examined the psychometric properties of the PTCI in two national samples of veteran men and women. Participants in Sample 1 (veterans from all service eras) and Sample 2 (recently separated veterans) completed the PTCI and additional measures of mental health symptoms. Confirmatory factor analyses indicated that a brief version of the PTCI (PTCI-9; 3-factor, nine-item) was a superior fit relative to other examined factor structures. Consistent with the original conceptualization of the measure, these factors were labeled: Negative cognitions about self, negative cognitions about the world, and self-blame. Scores on the PTCI-9 were differentially associated with the PTSD symptom clusters and with scores on self-report measures of external comorbidities. PTCI-9 scores were higher among individuals with trauma exposure and with a probable PTSD diagnosis. There was evidence of full (Sample 1) and partial (Sample 2) scalar invariance across men and women. Overall, the present study supports the use of the PTCI-9 as a measure of negative cognitions; however, scores may not be specific to PTSD and may represent a global negative thinking style. Even so, the PTCI-9 appears to be a suitable and abbreviated measure that could be used with veterans in research and clinical practice. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Gender differences in medication prescribing patterns for veterans with posttraumatic stress disorder: A 10-year follow-up study

Women veterans with posttraumatic stress disorder (PTSD) have historically received more psychiatric medications than men. The current analysis identified prescribing trends of medications recommended for (i.e., select antidepressants) and against (i.e., benzodiazepines, select antidepressants, antipsychotics, and select anticonvulsants) use in PTSD treatment among women and men in 2010-2019. All veterans receiving care for PTSD in 2019 were identified using national U.S. Department of Veterans Affairs (VA) administrative data. Multivariable logistic regression analyses, adjusted for demographic characteristics and psychiatric comorbidities, were used to contrast the likelihood of receiving a medication class across genders. Sensitivity analyses using identical selection methods were conducted for the calendar years 2010, 2013, and 2016. In 2019, 877,785 veterans received treatment for PTSD within the VA, 13.5% of whom were women. Across medication classes and years, women were more likely to receive all psychiatric medications of interest. Relative to men, women were slightly more likely to receive antidepressants recommended for PTSD in 2019, adjusted odds ratio (aOR) = 1.07, 95% CI [1.06, 1.09]. However, gender differences for medications recommended against use for PTSD were notably larger, including benzodiazepines, aOR = 1.62, 95% CI [1.59, 1.65]; anticonvulsants. aOR = 1.41, 95% CI [1.38, 1.44]; and antidepressants recommended against use for PTSD, aOR = 1.26, 95% CI [1.19, 1.33]. To inform tailored intervention strategies, future work is needed to fully understand why women receive more medications recommended against use for PTSD.

Pharmacological strategies for post-traumatic stress disorder (PTSD): From animal to clinical studies

Post-traumatic stress disorder (PTSD) is a disabling psychiatric condition with a critical familiar, personal, and social impact. Patients diagnosed with PTSD show various symptoms, including anxiety, depression, psychotic episodes, and sleep disturbances, complicating their therapeutic management. Only sertraline and paroxetine, two selective serotonin reuptake inhibitors, are approved by different international agencies to treat PTSD. In addition, these drugs are generally combined with psychotherapy to achieve positive results. However, these pharmacological strategies present limited efficacy. Nearly half of the PTSD patients do not experience remission of symptoms, possibly due to the high prevalence of psychiatric comorbidities. Therefore, in clinical practice, other off-label medications are common, even though the effectiveness of these drugs needs to be further investigated. In this line, antipsychotics, antiepileptics, adrenergic blockers, benzodiazepines, and other emerging pharmacological agents have aroused interest as potential therapeutic tools to improve some specific symptoms of PTSD. Thus, this review is focused on the most widely used drugs for the pharmacological treatment of PTSD with a translational approach, including clinical and preclinical studies, to emphasize the need to develop safer and more effective medications.
