Traumatic Brain Injury and Post-Deployment Binge Drinking among Male and Female Army Active Duty Service Members Returning from Operation Enduring Freedom/Operation Iraqi Freedom

Risk of Adverse Outcomes Among Veterans Who Screen Positive for Traumatic Brain Injury in the Veterans Health Administration But Do Not Complete a Comprehensive Evaluation: A LIMBIC-CENC Study

OBJECTIVE

To examine whether post-9/11 veterans who screened positive for mild traumatic brain injury (mTBI) but did not complete a Comprehensive TBI Evaluation (CTBIE) were at higher risk of subsequent adverse events compared with veterans who screened positive and completed a CTBIE. Upon CTBIE completion, information assessed by a trained TBI clinician indicates whether there is mTBI history (mTBI+) or not (mTBI-).

SETTING

Veterans Health Administration (VHA) outpatient services.

PARTICIPANTS

A total of 52 700 post-9/11 veterans who screened positive for TBI were included. The follow-up review period was between fiscal years 2008 and 2019. The 3 groups studied based on CTBIE completion and mTBI status were: (1) mTBI+ (48.6%), (2) mTBI- (17.8%), and (3) no CTBIE (33.7%).

DESIGN

This was a retrospective cohort study. Log binomial and Poisson regression models adjusting for demographic, military, pre-TBI screening health, and VHA covariates examined risk ratios of incident outcomes based on CTBIE completion and mTBI status.

MAIN MEASURES

Incident substance use disorders (SUDs), alcohol use disorder (AUD), opioid use disorder (OUD), overdose, and homelessness documented in VHA administrative records, and mortality as documented in the National Death Index, 3 years post-TBI screen. VHA outpatient utilization was also examined.

RESULTS

Compared with the no CTBIE group, the mTBI+ group had 1.28 to 1.31 times the risk of incident SUD, AUD, and overdose, but 0.73 times the risk of death 3 years following TBI screening. The mTBI- group had 0.70 times the risk of OUD compared with the no CTBIE group within the same period. The no CTBIE group also had the lowest VHA utilization.

CONCLUSIONS

There were mixed findings on risk of adverse events for the no CTBIE group relative to the mTBI+ and mTBI- groups. Future research is needed to explore the observed differences, including health conditions and healthcare utilization, documented outside VHA among veterans who screen positive for TBI.

Sex Differences in Postinjury Health Profiles Among U.S. Military Personnel Following Deployment-Related Concussion

Background: Women in the U.S. military are now authorized to serve in direct combat occupations. This may increase their risk of combat injuries, such as concussion, in future conflicts. Knowledge of sex differences in health profiles after concussion is paramount for military medical planning efforts. The purpose of this study was to assess sex-related differences in health profiles among U.S. military personnel following deployment-related concussion. Materials and Methods: We conducted a retrospective study of service members who sustained a concussion during combat deployment between 2004 and 2013. Postinjury diagnoses were abstracted from outpatient encounters in electronic health records for 24 months after concussion. We used hierarchical clustering to identify clusters, termed "health profiles," and logistic regression to determine whether sex predicted membership in the health profiles. Results: The study sample included 346 women and 4536 men with deployment-related concussion. Five postinjury health profiles were identified and classified as no morbidity, back pain, tinnitus/memory loss, posttraumatic stress disorder/postconcussion syndrome, and multimorbidity. Women relative to men had higher odds of membership in the back pain (odds ratio [OR] = 1.32; 95% confidence interval [CI] = 1.05-1.67) and multimorbidity profiles (OR = 1.44; 95% CI = 1.03-2.00) and lower odds than men in the tinnitus/memory loss profile (OR = 0.62; 95% CI = 0.42-0.91). Conclusions: Postinjury health profiles among U.S. service members differ by sex following deployment-related concussion, particularly with a higher burden of multimorbidity among women than men, which may require interdisciplinary care. Women also had higher odds of membership in the back pain profile and lower odds in the tinnitus/memory loss profile than men. To prepare for future military operations where women may have greater exposure to combat, continued research elucidating health-related sex differences after deployment-related concussion is imperative.

Examining the relationship between head trauma and opioid use disorder: A systematic review

OBJECTIVE

To examine recent literature and determine common clinical risk factors between antecedent traumatic brain injury (TBI) and the following development of opioid misuse and provide a framework for clinical identification of at-risk subjects and evaluate potential treatment implications within this association.

DESIGN

A comprehensive systematic literature search of PubMed was conducted for articles between 2000 and December 2022. Studies were included if the human participant had any head trauma exposure and any chronic opioid use or dependence. After eligibility criteria were applied, 16 studies were assessed for thematic trends.

RESULTS

Opioid use disorder (OUD) risks are heightened in cohorts with head trauma exposed to opioids while in the hospital, specifically with tramadol and oxycodone. Chronic pain was the most common predictor of long-term OUD, and continuous somatic symptoms associated with the TBI can lead to long-term opioid usage. Individuals who present with coexisting psychiatric conditions pose significantly more risk associated with a higher risk of long-term opioid use.

CONCLUSION

Findings indicate that therapists and clinicians must consider a risk profile for persons with TBI and follow an integrated care approach to account for mental health, prior substance misuse, presenting somatic symptoms, and current medication regimen during evaluation.

Changes in Outpatient Healthcare Utilization and Costs Following Mild Traumatic Brain Injury Among Service Members in the Military Health System by Preexisting Behavioral Health Condition Status

OBJECTIVE

To evaluate changes in healthcare utilization and cost following an index mild traumatic brain injury (mTBI) diagnosis among service members (SMs). We hypothesized that differences in utilization and cost will be observed by preexisting behavioral health (BH) diagnosis status.

SETTING

Direct care outpatient healthcare facilities within the Military Health System.

PARTICIPANTS

A total of 21 984 active-duty SMs diagnosed with an index mTBI diagnosis between 2017 and 2018.

DESIGN

This retrospective study analyzed changes in healthcare utilization and cost in military treatment facilities among SMs with an index mTBI diagnosis. Encounter records 1 year before and after mTBI were assessed; preexisting BH conditions were identified in the year before mTBI.

MAIN MEASURES

Ordinary least squares regressions evaluated difference in the average change of total outpatient encounters and costs among SMs with and with no preexisting BH conditions (eg, posttraumatic stress disorder, adjustment disorder). Additional regressions explored changes in utilization and cost within clinic types (eg, mental health, physical rehabilitation).

RESULTS

There was a 39.5% increase in overall healthcare utilization during the following year, representing a 34.8% increase in total expenditures. Those with preexisting BH conditions exhibited smaller changes in overall utilization (β, -4.9; [95% confidence interval (CI), -6.1 to -3.8]) and cost (β, $-1873; [95% CI, $-2722 to $-1024]), compared with those with no BH condition. The greatest differences were observed in primary care clinics, in which those with prior BH conditions exhibited an average decreased change of 3.2 encounters (95% CI, -3.5 to -3) and reduced cost of $544 (95% CI, $-599 to $-490) compared with those with no prior BH conditions.

CONCLUSION

Despite being higher utilizers of healthcare services both pre- and post-mTBI diagnosis, those with preexisting BH conditions exhibited smaller changes in overall cost and utilization. This highlights the importance of considering prior utilization and cost when evaluating the impact of mTBI and other injury events on the Military Health System.

Fetal alcohol spectrum disorders prevention and clinical guidelines research-workshop report

It is estimated that up to 1 in 20 people in the United States are affected by fetal alcohol spectrum disorders (FASD), an array of cognitive, emotional, physical and social disorders caused by exposure to alcohol during prenatal development. Common diagnoses encompassed within FASD include mood and behavioral disorders, memory and central nervous system deficits, attention-deficit/hyperactivity disorder (ADHD), slow growth and low body weight. While this condition affects a broad range of individuals and families, it is of particular concern in the military community, where cultural factors including an increased prevalence of alcohol misuse pose a unique set of challenges. To shed light on these issues and provide an overview of the existing research, programs, and clinical practice guidelines surrounding FASD, the Uniformed Services University of the Health Sciences (USUHS), in conjunction with FASD United, hosted the Workshop on Fetal Alcohol Spectrum Disorders Prevention and Clinical Guidelines Research on 21 September 2022 in Washington, DC. More than 50 attendees from academia, healthcare, federal agencies, and consumer advocacy organizations gathered to share research findings, lived experiences, and strategies for improving FASD prevention, diagnosis, interventions, and support.The workshop began with a series of presentations on FASD risk factors and causes, strategies for diagnosis and interventions, and impacts and lived experiences. Individuals and families affected by FASD spoke about the ways FASD, its symptoms, and the social stigma associated with it influences their daily lives, experiences at school and work, and access to healthcare. Several speakers highlighted the work of non-profit organizations and advocacy groups in supporting families affected by FASD and other challenges faced by military families more broadly. The workshop closed with a discussion of federal agency perspectives highlighting initiatives aimed at advancing research and access to care for women and families at-risk and those currently affected by FASD.

Calibrating the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) for detecting alcohol-related problems among Canadian, UK and US soldiers: cross-sectional pre-deployment and post-deployment survey results

OBJECTIVES

Excessive alcohol use can bring about adverse health and work-related consequences in civilian and military populations. Screening for excessive drinking can help identify individuals at risk for alcohol-related problems who may require clinical interventions. The brief validated measures of alcohol use such as the Alcohol Use Disorders Identification Test (AUDIT), or abbreviated AUDIT-Consumption (AUDIT-C), are often included in military deployment screening and epidemiologic surveys, but appropriate cut-points must be used to effectively identify individuals at risk. Although the conventional AUDIT-C cut-points ≥4 for men and ≥3 for women are commonly used, recent validation studies of veterans and civilians recommend higher cut-points to minimise misclassification and overestimation of alcohol-related problems. This study aims to ascertain optimal AUDIT-C cut-points for detecting alcohol-related problems among serving Canadian, UK and US soldiers.

DESIGN

Cross-sectional pre/post-deployment survey data were used.

SETTINGS

Comprised Army locations in Canada and UK, and selected US Army units.

PARTICIPANTS

Included soldiers in each of the above-mentioned settings.

OUTCOME MEASURES

Soldiers' AUDIT scores for hazardous and harmful alcohol use or high levels of alcohol problems served as a benchmark against which optimal sex-specific AUDIT-C cut-points were assessed.

RESULTS

Across the three-nation samples, AUDIT-C cut-points of ≥6/7 for men and ≥5/6 for women performed well in detecting hazardous and harmful alcohol use and provided comparable prevalence estimates to AUDIT scores ≥8 for men and ≥7 for women. The AUDIT-C cut-point ≥8/9 for both men and women performed fair-to-good when benchmarked against AUDIT ≥16, although inflated AUDIT-C-derived prevalence estimates and low positive predictive values were observed.

CONCLUSION

This multi-national study provides valuable information regarding appropriate AUDIT-C cut-points for detecting hazardous and harmful alcohol use, and high levels of alcohol problems among soldiers. Such information can be useful for population surveillance, pre-deployment/post-deployment screening of military personnel, and clinical practice.

Racial and Ethnic Differences in Deaths by Suicide, Drug Overdose, and Opioid-Related Overdose in a National Sample of Military Members With Mild Traumatic Brain Injury, 1999-2019

OBJECTIVE

To examine racial and ethnic differences in suicide and drug and opioid-related overdose deaths among a population-based cohort of military service members who were diagnosed with a mild traumatic brain injury (mTBI) during military service.

DESIGN

Retrospective cohort.

SETTING

Military personnel receiving care within the Military Health System between 1999 and 2019.

PARTICIPANTS

In total, 356 514 military members aged 18 to 64 years, who received an mTBI diagnosis as their index TBI between 1999 and 2019, while on active duty or activated.

MAIN MEASURES

Death by suicide, death by drug overdose, and death by opioid overdose were identified using International Classification of Diseases, Tenth Revision (ICD-10) codes within the National Death Index. Race and ethnicity were captured from the Military Health System Data Repository.

RESULTS

Overall crude rates were 38.67 per 100 000 person-years for suicide; 31.01 per 100 000 person-years for drug overdose death; and 20.82 per 100 000 person-years for opioid overdose death. Crude and age-specific rates for military members who self-identified as Other were higher than all other racial/ethnic groups for all 3 mortality outcomes. Adjusting for age, suicide rates for those classified as Other were up to 5 times that of other racial/ethnic groups for suicide, and up to 11 and 3.5 times that of other race/ethnicity groups for drug and opioid overdose death, respectively.

CONCLUSION

Findings extend previous knowledge regarding risk for suicide and deaths by drug overdose among those with mTBI and highlight new important areas for understanding the impact of race and ethnicity on mortality. Methodological limitations regarding classification of race and ethnicity must be addressed to ensure that future research provides a better understanding of racial and ethnic disparities in suicide and drug overdose mortality among military members with TBI.

Traumatic Brain Injury Classification Variability During the Afghanistan/Iraq Conflicts: Surveillance, Clinical, Research, and Policy Implications

OBJECTIVE

Challenges associated with case ascertainment of traumatic brain injuries (TBIs) sustained during the Afghanistan/Iraq military operations have been widespread. This study was designed to examine how the prevalence and severity of TBI among military members who served during the conflicts were impacted when a more precise classification of TBI diagnosis codes was compared with the Department of Defense Standard Surveillance Case-Definition (DoD-Case-Definition).

SETTING

Identification of TBI diagnoses in the Department of Defense's Military Health System from October 7, 2001, until December 31, 2019.

PARTICIPANTS

Military members with a TBI diagnosis on an encounter record during the study window.

DESIGN

Descriptive observational study to evaluate the prevalence and severity of TBI with regard to each code set (ie, the DoD-Case-Definition and the more precise set of TBI diagnosis codes). The frequencies of index TBI severity were compared over time and further evaluated against policy changes.

MAIN MEASURES

The more precise TBI diagnosis code set excludes the following: (1) DoD-only extender codes, which are not used in other healthcare settings; and (2) nonprecise TBI codes, which include injuries that do not necessarily meet TBI diagnostic criteria.

RESULTS

When comparing the 2 TBI classifications, the DoD-Case-Definition captured a higher prevalence of TBIs; 38.5% were classified by the DoD-Case-Definition only (>164 000 military members). 73% of those identified by the DoD-Case-Definition only were diagnosed with nonprecise TBI codes only, with questionable specificity as to whether a TBI occurred.

CONCLUSION

We encourage the field to reflect on decisions made pertaining to TBI case ascertainment during the height of the conflicts. Efforts focused on achieving consensus regarding TBI case ascertainment are recommended. Doing so will allow the field to be better prepared for future conflicts, and improve surveillance, screening, and diagnosis in noncombat settings, as well as our ability to understand the long-term effects of TBI.

Traumatic Brain Injury and Treatment of Behavioral Health Conditions

Traumatic brain injury (TBI) is a common neurological condition that results from an external force altering normal brain function, whether temporarily or permanently. A concussion is one type of TBI. TBIs vary greatly in severity, which concomitantly creates tremendous variability in their manifestation. The fingerprint of TBI is damage to the frontal areas of the brain, which, with sufficient magnitude, results in impairment of a person's ability to regulate cognition, emotion, and behavior. These consequences of TBI make recognition in the context of treating behavioral health conditions of utmost importance. TBI not only causes behavioral health problems but also produces associated deficits that can undermine the effectiveness of treatment for a behavioral health condition. This overview delineates key characteristics of TBI and describes its association with behavioral health conditions. Mechanisms underlying the relationship between TBI and behavioral health are presented, and a series of recommendations for professionals are proposed. This article is intended to raise awareness about TBI and simultaneously introduce key concepts for accommodating the effects of TBI in behavioral health care.

The Association of Lifetime and Deployment-Acquired Traumatic Brain Injury With Postdeployment Binge and Heavy Drinking

OBJECTIVE

To investigate associations of lifetime traumatic brain injury (LT-TBI) prior to an index deployment, and/or deployment-acquired TBI (DA-TBI), with postdeployment binge and heavy drinking.

SETTING

Soldiers from 3 Brigade Combat Teams deployed to Afghanistan in 2012.

PARTICIPANTS

A total of 4645 soldiers who participated in the Army STARRS Pre/Post Deployment Study and completed 4 assessments: T0 (1-2 months predeployment), T1 (upon return to United States), T2 (3 months postdeployment), and T3 (9 months postdeployment).

DESIGN

Prospective, longitudinal study controlling for baseline binge drinking.

MAIN MEASURES

Self-reported past month binge drinking (5+ alcoholic beverages on the same day) and past month heavy drinking (binge drinking at least weekly) at T2 and T3.

RESULTS

In total, 34.3% screened positive for LT-TBI, and 19.2% screened positive for DA-TBI. At T2 only, LT-TBI, but not DA-TBI, was associated with increased odds of binge drinking (adjusted odds ratio [AOR] = 1.39, 95% confidence interval [CI]: 1.20-1.60, P < .001) and heavy drinking (AOR = 1.28, 95% CI: 1.09-1.49, P = .007). Among the subgroup with LT-TBI, also having DA-TBI was associated with increased risk of heavy drinking at T3 (AOR = 1.42, 95% CI: 1.03-1.95, P = .047).

CONCLUSION

Routine screening for LT-TBI may help target efforts to prevent alcohol misuse among military members.

TBI as a Risk Factor for Substance Use Behaviors: A Meta-analysis

OBJECTIVE

To quantify the relationship between substance use behaviors before and after traumatic brain injury (TBI), to identify populations that may benefit more from targeted interventions to reduce the effect of substance use on TBI recovery, and to establish areas for further study.

DATA SOURCES

Studies were identified via literature searches using MEDLINE, PsychInfo, PsychArticles, PubMed, and GoogleScholar (published before January 2019), as well as reference section reviews and forward searches. Searches were conducted using search terms for TBI and substance use behaviors.

STUDY SELECTION

Studies were included if they (1) contained both a measure of TBI and a measure of substance use behaviors; (2) reported an effect size representing the relationship between substance use behaviors before and after TBI, compared TBI vs non-TBI groups on substance use behaviors controlling for pre-TBI substance use, or compared groups with differing TBI severity on subsequent substance use behaviors controlling for pre-TBI substance use; (3) were written in English; and (4) were human subjects research. Studies examining effects of substance use intervention for people sustaining TBI were excluded from this study.

DATA EXTRACTION

Study variables included substance use behaviors, TBI severity, time since TBI, military status, age, race, and sex.

DATA SYNTHESIS

Substance use behaviors had a small but statistically significant decrease after moderate-severe TBI. After moderate-severe TBI, there was a statistically significant decline in both substance use (d=-0.29, P<.01) and negative substance use consequences (d=-0.67, P=.01). There was no significant change in substance use behaviors after mild TBI.

CONCLUSIONS

Substance use behaviors had a small decrease after moderate to severe TBI and no significant change after mild TBI. Study findings suggest the need for accurate assessment to identify those at greatest risk for problematic substance use behaviors after TBI.

Postdeployment Polytrauma Diagnoses Among Soldiers and Veterans Using the Veterans Health Affairs Polytrauma System of Care and Receipt of Opioids, Nonpharmacologic, and Mental Health Treatments

OBJECTIVES

To determine the proportion of Army soldiers who utilized care in the Veterans Health Administration (VHA) Polytrauma System of Care (PSC) within the postdeployment year and to describe prevalence of polytrauma diagnoses, and receipt of opioids, nonpharmacologic treatments (NPTs), and mental health treatments in the VHA during the year following first PSC utilization.

SETTING

VHA's 4-tiered integrated PSC network of specialized rehabilitation services for military members and veterans with polytrauma.

PARTICIPANTS

Soldiers and veterans who used the PSC during the postdeployment year after an Afghanistan or Iraq deployment ending in fiscal years 2008-2011.

DESIGN

Population-based cohort study.

MAIN MEASURES

Prevalence of polytrauma diagnoses (ie, traumatic brain injury [TBI], posttraumatic stress disorder [PTSD], and chronic pain [CP]), VHA utilization rates of opioid prescriptions, NPT, and specialty mental health treatment within 1 year of PSC utilization.

RESULTS

In total, 2.6% of the sample (n = 16 590) used the PSC during the postdeployment year. Among PSC users, CP (76.5%), PTSD (53.1%), and TBI (48.6%) were common and more frequently found together than in isolation; 26.6% filled an opioid prescription, 35.5% received at least 1 NPT, and 83.8% received specialty mental health treatment in the VHA within 1 year of PSC utilization.

CONCLUSION

CP was the most common polytrauma condition among PSC users, highlighting the importance of incorporating interdisciplinary pain management approaches within the PSC, with an effort to reduce reliance on long-term opioid therapy and improve rehabilitation.

Exploration of the association of selected pain diagnoses with risky alcohol use among active duty soldiers

BACKGROUND

Pain and its consequences remain of concern, particularly in high-risk occupations such as the military. Alcohol is a legal and accessible means of self-medication, and risky alcohol use is associated with potentially serious consequences. This exploratory analysis aimed to better understand the association of selected pain diagnoses with risky alcohol use among soldiers returning from deployment. Methods: Analysis of data from active duty soldiers returning from Afghanistan or Iraq deployments in fiscal years 2008-2011 who completed Department of Defense health questionnaires after deployment (n = 267,100). Each questionnaire included self-reported alcohol consumption and items yielding AUDIT-C screening scores. Military Health System data were used to identify diagnoses of pain-related conditions. Results: About 70% of soldiers had none of the selected pain diagnoses either pre- or post-deployment. 10% had incident pain diagnoses (only post-deployment), 7% had persistent pain diagnoses (both pre- and post-deployment), and 13% had remitted pain diagnoses (only pre-deployment). On the AUDIT-C, 39% screened positive for at-risk drinking and 6% were likely to have severe alcohol problems. Half of the respondents reported any binge drinking; 20% at least monthly binge drinking. Logistic regression analyses found reduced odds of risky alcohol use post-deployment in association with incident and persistent pain diagnoses, compared to no pain diagnoses pre- or post-deployment. Conclusions: Pain diagnoses, binge drinking, and risky alcohol use were prevalent among this sample of Army soldiers. An inverse relationship was found between pain diagnosis (incident, persistent) and risky alcohol use post-deployment. Attention should continue to be paid to risky alcohol use in this population, yet these exploratory findings do not suggest that soldiers with the pain diagnoses used in this study are at greater risk. Combat exposure, traumatic brain injury, and psychological health were more important predictors, and should continue to warrant enhanced alcohol screening.

Gender Differences in Outcomes after Traumatic Brain Injury among Service Members and Veterans

This scoping study describes the range of outcomes in traumatic brain injury (TBI) studies of military service members and veterans addressing gender differences. A secondary purpose is to identify differences in outcomes between male and female participants in such studies. We searched PubMed, CiNAHL, and PsycInfo databases for relevant articles. Two reviewers independently screened results. Of 822 unique titles and abstracts screened for eligibility, 55 full articles were reviewed, with 29 studies meeting full inclusion criteria. Twenty of the 29 included studies used retrospective designs and all but two used data collected from Veterans Affairs or Department of Defense health care settings. TBI was diagnosed by self-report, screening, and evaluation procedures, and medical record documentation. Ten different outcome categories were identified among the included studies. In general, female service members and veterans have not been well represented in TBI outcomes research. Evidence suggests that female veterans with mild TBI (mTBI) report more neurobehavioral symptoms and use more outpatient services than male veterans. Studies also indicate that female veterans with TBI are more frequently diagnosed with depression. Additional research is essential to support precision treatment recommendations for female veterans with TBI, as women represent a growing proportion of the patients served by the Veterans Health Administration. LEVEL OF EVIDENCE: IV.

Sex Differences in Traumatic Brain Injury: What We Know and What We Should Know

There is growing recognition of the problem of male bias in neuroscience research, including in the field of traumatic brain injury (TBI) where fewer women than men are recruited to clinical trials and male rodents have predominantly been used as an experimental injury model. Despite TBI being a leading cause of mortality and disability worldwide, sex differences in pathophysiology and recovery are poorly understood, limiting clinical care and successful drug development. Given growing interest in sex as a biological variable affecting injury outcomes and treatment efficacy, there is a clear need to summarize sex differences in TBI. This scoping review presents an overview of current knowledge of sex differences in TBI and a comparison of human and animal studies. We found that overall, human studies report worse outcomes in women than men, whereas animal studies report better outcomes in females than males. However, closer examination shows that multiple factors including injury severity, sample size, and experimental injury model may differentially interact with sex to affect TBI outcomes. Additionally, we explore how sex differences in mitochondrial structure and function might contribute to possible sex differences in TBI outcomes. We propose recommendations for future investigations of sex differences in TBI, which we hope will lead to improved patient management, prognosis, and translation of therapies from bench to bedside.

Traumatic Brain Injury and Psychiatric Co-Morbidity in the United States

The objective of the present study was to provide a nationally representative psychiatric epidemiologic investigation of traumatic brain injury (TBI) and its co-morbid conditions. Data from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC-III) collected between 2012 and 2013 was used. Results indicated that TBI was significantly associated with any lifetime mental health (AOR = 2.32, 95% CI = 1.65-3.70), substance use disorder (AOR = 1.57-1.01-2.42), and violent (AOR = 1.65, 95% CI = 1.03-2.65) and nonviolent (AOR = 1.84, 95% CI = 1.25-2.70) criminal behaviors. In our study, TBI was highly comorbid with psychiatric disorders and especially antisocial behaviors, both violent and non-violent.

Alcohol Use Among Never-Deployed U.S. Army Reserve and National Guard Soldiers: The Effects of Nondeployment Emotions and Sex

BACKGROUND

Limited research shows that mental health problems are prevalent among never-deployed soldiers and many experience negative emotions related to their nondeployment. U.S. Army Reserve/National Guard (USAR/NG) soldiers are also at high risk for alcohol misuse. However, it is not known if nondeployment emotions contribute to an increased risk of alcohol misuse among never-deployed USAR/NG soldiers.

METHODS

Data are from Operation: SAFETY (Soldiers and Families Excelling Through the Years), an ongoing study of USAR/NG soldiers. We used regression models to examine the relations between nondeployment emotions, assessed by the Non-Deployment Emotions (NDE) Questionnaire, and a range of alcohol use outcomes, assessed by the Alcohol Use Disorders Identification Test and standard quantity and frequency questions, among a sample of never-deployed soldiers who were partnered at baseline (N = 174). Final models controlled for years of military service, current number of close military friends in the social network, marital satisfaction, and depression. We also tested for potential differences in these associations by sex.

RESULTS

Nondeployment emotions were associated with frequency of getting drunk (adjusted risk ratio [aRR] = 1.02, 95% CI: 1.01, 1.04; p < 0.05) and typical number of drinks consumed during a drinking episode (aRR = 1.03, 95% CI: 1.01, 1.04; p < 0.01). Nondeployment emotions had a trend-level association with percent of days drinking (adjusted odds ratio = 1.05, 95% CI: 1.00, 1.11; p = 0.055). Nondeployment emotions had a significant interaction with sex (p < 0.05) on the likelihood of alcohol problems, such that only male soldiers experienced a greater likelihood of alcohol problems when they had highly negative nondeployment emotions. There was no relation between nondeployment emotions and alcohol problems among female soldiers.

CONCLUSIONS

Findings demonstrate that greater nondeployment emotions are associated with increased alcohol use among never-deployed USAR/NG soldiers. The NDE Questionnaire may assist in identifying those at highest risk for alcohol problems.
