Sleep disorder symptoms and suicidal urges among US Marines seeking suicide treatment: Findings from an intensive daily assessment study

BackgroundRates of suicide in United States Marines are among the highest in the military, and sleep disorder symptoms are a known risk factor for suicide in the military. Intensive ecological momentary assessments (EMA) might improve the ability to detect periods that are characterized by increased suicidal ideation. Marines who were at high risk for suicide were intensively assessed for one month on sleep, suicidal urges, posttraumatic stress disorder (PTSD) and depression symptoms. MethodsU.S. Marines (N = 40) who had a past month suicide attempt or suicidal urges with intent were sent EMA for 28 days. Mixed effects models explored associations among daily sleep, suicidal urges, PTSD, and depression symptoms. ResultsWorsened sleep indicators on a given night significantly predicted higher maximum values of suicide urges the following day. Worse sleep quality the prior night was moderately associated with more severe PTSD symptoms and depression symptoms. Greater severity of PTSD symptoms and depression symptoms were strongly associated with both the maximum value and the range of suicide urges. PTSD and depression symptoms mediated the relationship between sleep quality and suicidal urges. Participants reported that 0000–0300 had the greatest elevation in endorsement of highest suicide urges. LimitationsThis study had a small sample size may not generalize beyond active duty Marines. ConclusionsPoor sleep quality and other sleep markers were an important risk factor for suicidal urges among U.S. Marines. This relationship was mediated by exacerbations in PTSD and depression symptoms. Interventions are needed to interrupt suicide risk during and following nights with poor sleep.

Camp Lejeune Marine Cancer Risk Assessment for Exposure to Contaminated Drinking Water From 1955 to 1987

This study utilizes guidance from the United States Environmental Protection Agency (USEPA) and the Agency for Toxic Substances and Disease Registry (ATSDR) to calculate the cancer risk to United States Marines who were exposed to carcinogens in drinking water at Marine Corps Base Camp Lejeune. Camp Lejeune is a 233-square-mile Marine Corps training facility in North Carolina. From 1953 to 1987, nearby dry cleaners, landfills, and underground storage tanks contaminated drinking water systems that served Camp Lejeune (ATSDR, 2017). Some of the most toxic contaminants found in the drinking water modeled by ATSDR include benzene, tetrachloroethylene (PCE), trichloroethylene (TCE), trans-1,2-dichloroethylene (DCE), and vinyl chloride (VC). ATSDR utilized MODFLOW and EPANET modeling software to determine the level of contamination in the three main drinking water systems at Camp Lejeune: Tarawa Terrace, Holcomb Boulevard, and Hadnot Point. This paper presents an application of methodology to quantify cancer risk for the Marines who lived and served at Camp Lejeune from 1953 to 1987 using ATSDR’s health assessment, chemical contaminant modeling, and USEPA methodology. While VC and TCE were found to be the main risk drivers, benzene and PCE also contributed to the cumulative cancer risk. This analysis shows (1) That the cancer risk was greatest during the 1970s and 1980s and (2) that the inhalation exposure pathway had the greatest contribution to overall cancer risk followed by ingestion, with the smallest contribution from dermal absorption.

Don't Shoot Me: Potential Consequences of Force-on-Force Training Modulate the Human Stress Response.

Jensen, AE, Bernards, JR, Hamilton, JA, Markwald, RR, Kelly, KR, and Biggs, AT. Do not shoot me: potential consequences of force-on-force training modulate the human stress response. J Strength Cond Res 37(9): 1761-1769, 2023-Close-quarters combat (CQC) engagements trigger the "fight-or-flight" response, activating the sympathetic nervous system and hypothalamic-pituitary-adrenal axis in response to perceived threats. However, it has yet to be shown if a force-on-force (FoF) CQC training environment will lead to adaptations in the physiological stress response or performance. United States Marines and Army infantry personnel participated in a 15-day CQC training program. The CQC program focused heavily on FoF training with the use of nonlethal training ammunition (NLTA). Data collections occurred on training days 1 and 15, during a simulated FoF-hostage rescue (HR) scenario and photorealistic target drill. For the FoF-HR, subjects were instructed to clear the shoot house, rescue the hostage, and only shoot hostile threat(s) with NLTA. The photorealistic target drills were similar, but replaced the role players in the FoF-HR with paper targets. Salivary alpha-amylase (sAA) and salivary cortisol were obtained immediately before entering and exiting the shoot house. Time to completion significantly decreased, between days 1 and 15, for both the FoF-HR and the photorealistic drills by 67.7 and 54.4%, respectively ( p < 0.05). Analyses revealed that the change in sAA, nonsignificantly, doubled from day 1 to 15 during FoF-HR ( p > 0.05), whereas the change in sAA decreased during the photorealistic drills across days ( p < 0.05). Cortisol was significantly higher during the FoF-HR in comparison to the photorealistic drills ( p < 0.05). These data suggest that potential consequences of FoF training heighten the stress response in conjunction with enhanced performance.

Applying User-Centered Design to U.S. Military Acquisition Requests

This study presents the concept testing results of a low-fidelity user-centered design (UCD) tool applied to the U.S. military acquisition request process. A purposive, random, small-sampled population of United States Marines used a UCD-based Design Worksheet to aid their own design process as they prepared a simulated acquisition request for equipment modifications. The results indicated that Marines engaged in the robust discovery and design exploration while using the Design Worksheet. While Marines had some challenges with understanding how to navigate the Design Worksheet, they found it valuable as a prompt for a useful, more productive thinking process. Importantly, Marines indicated that they would adopt the Design Worksheet to complete a real acquisition design request. Considerations for how the Design Worksheet supported their equipment modification analysis, and whether similar HCI or UCD tools could be pursued and adopted in comparable design environments are discussed.

Tactical Masters Athletes: BMI Index Classifications.

Understanding the nexus between aging, physical activity, and obesity has been a source of ongoing investigation. A considerable amount of research has focused on Masters athletes in this regard, suggesting a beneficial relationship between Masters sport participation and a healthy body mass index (BMI). Some consider Active Duty military personnel as tactical athletes. As such, it is of interest to determine if aging Active Duty military personnel (or Masters Tactical Athletes) might have a similar BMI as other Masters athletes (MA). As such, this investigation examined previously recorded data of Active Duty Enlisted United States Marines (n = 402, male, 46–50 years old). The BMI of the Marines was stratified into categories of: underweight, normal, overweight, and obese. The Marines obesity prevalence was compared to US adult males (40–59 years) as well as male North American MA who competed at the 2009 Sydney World Masters Games. The Marines obesity prevalence was significantly lower than US adult males (p < 0.001) and those MA that competed in softball (p < 0.001); however, it was similar to MA that competed in football, track/field, swimming, and volleyball (p > 0.05). The average Marine BMI = 26.7 kg/m2 was similar to MA who competed in football, swimming, and volley ball (p > 0.05); however, it was higher than MA who competed in track/field (p < 0.05) and lower than MA who played softball (p < 0.05). It should be noted that the average BMI for the Marines and all MA sport categories were classified as being overweight. Within the parameters of this investigation, Tactical MA (i.e., aging US Marines) enjoy a similar beneficial BMI as other North American MA.

INFLUENCE OF LIMB DOMINANCE AND SHOULDER INJURY ON STRENGTH AND EXPLOSIVE FORCE IN US MARINES.

The specialized roles of many military personnel require specific skills and high physical demands, placing unique stresses on the shoulders and increasing risk of injury. As normal dominant/nondominant shoulder asymmetries have been established in military personnel, bilateral strength comparisons must be understood in context of daily physical demands to monitor patients' progress or readiness to return to duty. This study aims to assess bilateral differences in strength and explosive force in United States Marines with a history of dominant or nondominant shoulder pathology. Cross-Sectional. A total of 52 full-duty, male US Marines with a shoulder injury within the prior year participated. Bilateral isokinetic shoulder internal (IR) and external (ER) rotation strength, and peak force (Peak Force) and average rate of force production (Avg Rate) during an explosive push-up were collected. Dominant versus nondominant side data were independently examined within each group (DOM: dominant injury, NOND: nondominant injury). Comparison between DOM and NOND, as well as previously published CON (no history of shoulder injury) was also completed. NOND (n = 26) demonstrated significantly less IR (p < 0.001) and ER (p = 0.003) strength and Peak Force (p = 0.001) and Avg Rate (p = 0.047) on the injured side, while DOM (n = 26) demonstrated no bilateral differences in strength or push-up performance. Comparison between the three groups showed that NOND demonstrated significantly less ER strength than CON (p = 0.022). Military personnel demonstrate asymmetric strength patterns likely due to increased demand of the dominant shoulder. US Marines with a history of injury to the nondominant shoulder performed differently than those with a dominant side injury, presenting with both strength and push-up asymmetries. They also demonstrated significant ER strength deficits compared to CON. Common clinical practice and previous literature often compare injured and uninjured limbs or injured individuals to healthy controls, but further distinction of dominant or nondominant side may provide more accurate information needed to develop targeted treatment strategies. Recognizing unique occupational demands and how patients may present differently with dominant versus nondominant side shoulder injuries are important considerations for ensuring accurate assessment and effective individualized rehabilitation. 3.

Comparison Of United States Marine Corps Physical Fitness Test And Combat Fitness Test Results

For active duty United States Marines physical and combat fitness is essential to be battle-ready and is necessary for day-to-day effectiveness. To help instill habits of self-discipline and maintain physical and combat fitness the United States Marines Corps (USMC) have installed a Physical Fitness Test (PFT) to measure physical fitness levels and a Combat Fitness Test (CFT) to asses a Marine’s functional fitness as it relates to the demands and rigors of combat operations. The USMC PFT involves three events; pull-ups/push-ups (PU), two-minute timed abdominal crunches/sit-ups (AC), and a timed three-mile run (RUN). The USMC CFT also involves three events; Movement to Contact (MTC), two-minute timed Ammunition Lift (AL), and Maneuver-Under-Fire (MANUF). PURPOSE: The purpose of this study was to investigate relationships between PFT (PU, AC, and RUN) and CFT (MTC, AL, and MANUF) scores assessed by active duty Marines. METHODS: The PFT and CFT scores from 19,678 active duty enlisted USMC males (age 22.5±1.3 years, height 1.77±0.07 m, body mass 79.4±10.3 kg) were analyzed. Pearson correlation coefficients (r) were calculated between the PFT and CFT total scores as well as individual events. RESULTS: The PFT mean±sd scores were as follows: PU=18.0±5.0 (pull-ups), AC=111.2±9.0 (repetitions), RUN=1377.0±131.4 sec, PFT total=249.6±29.6. The CFT mean±sd scores were as follows: MTC=172.5±16.3 sec, AL=113.2±10.4 repetitions, MANUF=138.3±17.2 sec, CFT total=271.6±25.6. Moderate significant (p<0.01) correlations were found between: the PFT total and MTC (r=-0.47), PFT total and MANUF (r=-0.42), PFT total and CFT total (r=0.50), RUN and MTC (r=0.46), RUN and CFT total (r=-0.43), & PU and CFT total (r=0.41). All other correlations between variables yielded “no to low” association. CONCLUSION: Within the parameters of this study, PFT and CFT event scores ranged from "no" to "moderate" correlations suggesting that different fitness aspects are being assessed and supports the need for both the PFT and CFT assessments.

Self-Reported Concussion Symptomology during Deployment: Differences as a Function of Injury Mechanism and Low-Level Blast Exposure.

Traumatic brain injury (TBI), which can result from either direct impact to the head or blast exposure, has been the leading cause of morbidity and mortality in recent military conflicts. However, little research has compared mTBIs by mechanism of injury. The present research addressed two research questions: (1) Are blast-related mTBIs (mbTBIs) associated with significantly more symptoms than impact-related mTBIs (miTBIs), and (2) are mTBIs associated with more self-reported symptoms among service members with higher (vs. lower) risk of low-level blast (LLB) exposure. We obtained data from 181,423 active duty enlisted United States Marines deployed between 2003 and 2012, who completed the Post-Deployment Health Assessment. We examined the self-reported symptoms of Marines who completed an mTBI screen and could be classified as at high or low risk for LLB exposure, using their military occupation as a proxy (n = 12,013). Symptoms were compared as a function of blast exposure (blast vs. impact), probable mTBI (yes vs. no), occupational risk of LLB (high vs. low), and symptom type (neurological vs. musculoskeletal vs. immunological). Overall, musculoskeletal symptoms were reported more frequently than neurological and immunological symptoms. However, Marines with probable mTBIs (regardless of mechanism of injury) and those with probable mbTBIs specifically reported more neurological symptoms, which rose to the level of musculoskeletal symptom reporting. Among Marines with probable mTBI, those with high risk of LLB exposure also reported significantly more neurological symptoms. Our results indicate that mbTBIs and miTBIs may be fundamentally different, and that LLB may increase susceptibility to injury.

Dynamic changes in marines' reports of PTSD symptoms and problem alcohol use across the deployment cycle.

Posttraumatic stress disorder (PTSD) and alcohol misuse are commonly co-occurring problems in active-duty service members (SMs) and veterans. Unfortunately, relatively little is known about the temporal associations between these problems in the acute period following exposure to combat stressors. Discerning the temporal associations between these problems across the deployment cycle could inform prevention and treatment efforts. In this study, we examined the association between PTSD symptom severity and problem alcohol use in a large cohort of United States Marines (n = 758) evaluated prior to deployment and approximately 1, 5, and 8 months postdeployment. Results indicate that problem alcohol use was associated with a subsequent exacerbation of PTSD symptoms between the 1st and 2nd and 2nd and 3rd postdeployment assessments. PTSD symptom severity was associated with increased problem alcohol use between the 1st and 2nd postdeployment assessments. These findings suggest that problem drinking may lead to new onset or worsening of PTSD symptoms over time and that SMs with greater PTSD symptom severity upon returning from deployment may increase alcohol use in the weeks immediately following homecoming.

Impact of TBI, PTSD, and Hearing Loss on Tinnitus Progression in a US Marine Cohort.

Mild TBI (TBI) is associated with up to a 75.7% incidence of tinnitus, and 33.0% of tinnitus patients at the US Veterans Administration carry a diagnosis of post-traumatic stress syndrome (PTSD). Yet factors contributing to new onset or exacerbation of tinnitus remain unclear. Here we measure intermittent and constant tinnitus at two time points to ascertain whether pre-existing or co-occurring traumatic brain injury (TBI), hearing loss, or post-traumatic stress disorder (PTSD) predicts new onset, lack of recovery and/or worsening of tinnitus in 2,600 United States Marines who were assessed before and after a combat deployment. Ordinal regression revealed that constant tinnitus before deployment was likely to continue after deployment (odds ratio [OR] = 28.62, 95% confidence interval [CI]: 9.84,83.26). Prior intermittent tinnitus increased risk of post-deployment constant tinnitus (OR = 4.95, CI: 2.97,8.27). Likelihood of tinnitus progression increased with partial PTSD (OR = 2.39, CI: 1.50,3.80) and TBI (OR = 1.59, CI: 1.13,2.23), particularly for blast TBI (OR = 2.01, CI: 1.27,3.12) and moderate to severe TBI (OR = 2.57, CI: 1.46,4.51). Tinnitus progression also increased with low frequency hearing loss (OR = 1.94, CI: 1.05,3.59), high frequency loss (OR = 3.01, CI: 1.91,4.76) and loss across both low and high frequency ranges (OR = 5.73, CI: 2.67,12.30). Screening for pre-existing or individual symptoms of PTSD, TBI, and hearing loss may allow for more focused treatment programs of comorbid disorders. Identification of those personnel vulnerable to tinnitus or its progression may direct increased acoustic protection for those at risk.

From Vietnam, VA, to Iraq, CA: The Spectrality of Violence in An-My Lê’s Small Wars and 29 Palms

This paper focuses on two of the three photographic projects included in An-My Le’s Small Wars (2005). The first one, Small Wars (1999–2002) represents Vietnam War reenactors staging combat in the Virginian forest. In the second project, 29 Palms (2003–2004), Le turns her camera on United States Marines preparing for deployment in Iraq in the California desert. In the series, warfare is either reenacted or rehearsed without the violent outcome of combat being tangibly represented. However, the spectrality of past and impending violence permeates the photographs and confirms the haunting legacy of war iconography. We will examine how Le uses the American landscape and creates images haunted by the invisible visibility of violence.

‘Protection against the Lust of Men’: Progressivism, Prostitution and Rape in the Dominican Republic under US Occupation, 1916–24

This article explains the disparity between the United States (US) military government's efforts to defend and empower local women during the first occupation of the Dominican Republic (1916–24) and its reputation for tolerating sexual assault. It argues that US officials, inspired by a progressive ideology that linked the social, economic and political spheres, set out to reshape Dominican sexual and gender norms as a means to ensure political stability. Yet, these efforts fell victim to both Dominican and US Marines’ conceptions of gender and normative sexuality. Building upon a thriving body of scholarship that addresses the significance of US efforts to redefine Dominican gender norms, this article analyses the military government's policies towards women and provost courts’ responses to sexual assault. It concludes that, combined with an aggressive anti‐prostitution campaign, the military government's reforms succeeded only in creating an atmosphere favourable to crimes against women. Moreover, rape and the way it was prosecuted revitalised the patriarchal norms that US officials had set out to transform, thus setting the stage for the regime of Rafael Leonidas Trujillo, whose thirty‐year dictatorship depended on the conspicuous control of women. Thus, US policies and attitudes not only ensured the failure of progressive reform but also contributed to the ongoing subjugation of the very women the military government had pledged to empower.

“To Start Something to Help These People”: African American Women and the Occupation of Haiti, 1915–1934

In 1915, United States marines arrived in Haiti. Their landing signaled the beginning of an occupation that would cripple Haiti long after it ended in 1934. Scholars have offered compelling insights into African American opposition to the erosion of Haitian sovereignty. But this scholarship has prioritized the activism of Black men and male-dominated institutions while deemphasizing the complex reaction of Black women to the occupation. This article highlights that overlooked reaction. It shows that some leading Black women continued to speak of the need to civilize Haiti. Others constructed organizations that emerged from imperialist discourses and sometimes relied upon imperialist structures. By demonstrating how middle-class and elite Black women navigated a transitional moment in Black intellectual history—adhering to traditional notions of racial uplift, civilization, and respectability even as they presented radical calls for Haitian liberation—my paper contributes to the literature on the US occupation of Haiti while establishing new lines of inquiry into Black political culture, women’s organizing, and US imperialism.

The impact of multiple concussions on emotional distress, post-concussive symptoms, and neurocognitive functioning in active duty United States marines independent of combat exposure or emotional distress.

Controversy exists as to whether the lingering effects of concussion on emotional, physical, and cognitive symptoms is because of the effects of brain trauma or purely to emotional factors such as post-traumatic stress disorder or depression. This study examines the independent effects of concussion on persistent symptoms. The Defense Automated Neurobehavioral Assessment, a clinical decision support tool, was used to assess neurobehavioral functioning in 646 United States Marines, all of whom were fit for duty. Marines were assessed for concussion history, post-concussive symptoms, emotional distress, neurocognitive functioning, and deployment history. Results showed that a recent concussion or ever having experienced a concussion was associated with an increase in emotional distress, but not with persistent post-concussive symptoms (PPCS) or neurocognitive functioning. Having had multiple lifetime concussions, however, was associated with greater emotional distress, PPCS, and reduced neurocognitive functioning that needs attention and rapid discrimination, but not for memory-based tasks. These results are independent of deployment history, combat exposure, and symptoms of post-traumatic stress disorder and depression. Results supported earlier findings that a previous concussion is not generally associated with post-concussive symptoms independent of covariates. In contrast with other studies that failed to find a unique contribution for concussion to PPCS, however, evidence of recent and multiple concussion was seen across a range of emotional distress, post-concussive symptoms, and neurocognitive functioning in this study population. Results are discussed in terms of implications for assessing concussion on return from combat.

Of Tablecloths and Soviet Relics: A Study of the Banner of Victory (Znamia Pobedy)

The Second World War produced many iconic photographs. Among these were two famous photographs of flag-raisings. Americans are most familiar with Joe Rosenthal’s photo of United States Marines raising the Stars and Stripes over Mount Sarabachi on the Japanese island of Iwo Jima. In the Soviet Union and modern Russia, the best known flag-raising photo from the war is Evgennyi Khaldei’s photo of Soviet soldiers raising the red banner with the hammer, sickle and star over the Reichstag in Berlin. When this photo is published it is usually labeled in Russian as “Znamia Pobedy nad Reikhstagom”, or “Banner of Victory over the Reichstag”. It is not only used to illustrate the end of the war, but has also become a powerful symbol of the Soviet victory over Fascist Germany. In some written accounts about the photograph it is linked to the “Znamia Pobedy”, or Victory Banner – a historical flag, museum artifact, and Soviet relic that is still treasured in post-Soviet Russia. This banner (and reproductions of it) have become a regular feature of the Victory Day parades held annually on May 9 since the end of the war. Some discussions of the Znamia Pobedy suggest that the flag in Khaldei’s photo and the flag in the museum are one in the same. Others, however, suggest that these are two different flags and that they are just a few of the many red banners raised over the Reichstag building during the final battle for Berlin. Further confusing the issue, the term “Znamia Pobedy” also refers to replicas of the museum artifact flag that are used on Victory Day. In early post-Soviet Russia a proposal was made to change the design of the Victory Banner to eliminate Soviet symbolism. However, changing a relic is not easy to do, so today the Znamia Pobedy retains its hammer, sickle, and star. This paper will examine the many aspects of the Victory Banner including the Khaldei photo, the museum relic, and the role of the banner in Russia and elsewhere today.

Changes in Urine Parameters After Desert Exposure: Assessment of Stone Risk in United States Marines Transiently Exposed to a Desert Environment

Living in a desert environment has been associated with a higher incidence of kidney stone formation, likely because of concentrated urine output, higher production of vitamin D and genetic predisposition. We determined the changes in urinary parameters after a group of United States Marines temporarily transitioned from a temperate environment to a desert environment. A total of 50 Marines completed a questionnaire and performed 3, 24-hour urine collections before mobilization to the desert, after 30 days in the desert and 2 weeks after returning from the desert. Daily urine output decreased 68% to 0.52 L despite marked increased fluid intake (17 L per day). Total daily urinary excretion of calcium, uric acid, sodium, magnesium and potassium in the desert decreased by 70%, 41%, 53%, 22% and 36%, respectively. Urinary pH decreased from 6.1 to 5.6 while in the desert, and citrate and oxalate had minimal changes. After their return from the desert, apart from a decrease of 22% in oxalate, there were no statistically significant differences from baseline. While in the desert, relative supersaturation risks of uric acid and sodium urate were increased 153% and 56%, respectively. Brushite relative supersaturation decreased 24%. After their return there was no statistical difference from baseline. Our findings suggest that the kidneys preserved water and electrolytes while the Marines were subjected to the desert environment. Despite this conservation, relative saturations indicate increased risk of stones in healthy men exposed to a desert environment with rapid resolution upon return.

Cost-Effectiveness of Primary Prevention Strategies for Nephrolithiasis

Stone disease is a highly prevalent condition associated with substantial cost and morbidity. We evaluated the cost-effectiveness of a primary prevention strategy. A decision analysis model was constructed to compare the cost of ad hoc management of symptomatic stones vs the cost of primary prevention. A literature search was performed to determine the incidence of stone disease, the effectiveness of nonmedical prevention strategies and cost associated with stone management. One and 2-way sensitivity analyses were performed to determine conditions under which a strategy of primary prevention might be cost-effective. Assuming a 1% incidence of stones, a 50% risk reduction and a $100 cost per individual per year for primary prevention, the model was used to calculate the overall costs per individual per year without and with a primary prevention strategy of $46 and $123, respectively. One-way sensitivity analyses indicated that primary prevention was cost-effective if the incidence of stones exceeded 4.3% yearly or the cost of prevention was less than $23 per person yearly. Varying other factors (risk reduction, probability of requiring surgery, hours of lost work, emergency room cost) failed to reach cost equivalence under any circumstances or required unrealistic assumptions. Preventive strategies were more costly than no prevention unless the incidence of stone disease was at least 1%, the cost did not exceed $20 per person per year and the prevention strategy was at least 50% effective in preventing stones. Primary prevention strategies for stone disease have not been sufficiently evaluated but can theoretically be cost-effective if the population has a sufficiently high incidence of stone disease and the strategy is of low cost and moderately effective.

Emotional distress and health risk behaviours of mothers of United States marines*

The aim was to explore emotional distress and health risk behaviours of mothers of servicemen. The study was inspired by the first author's clinical practice in primary care among women who reported significant emotional distress surrounding impending deployment of their sons. Thousands of US service members have been deployed in the current wars. The potentially profound effects of deployment on emotional distress of military spouses and children have been documented; however, mothers of servicemen have not been studied. This was an exploratory descriptive study to determine self-reported levels of emotional distress and health risk behaviours in the mothers of deployed male US Marines compared with mothers of male Marines not currently deployed. Mothers were accessed via a voluntary online support organization. Mothers of deployed sons reported significantly higher levels of emotional distress and more health risk behaviours compared with mothers of sons not deployed. Many of the mothers in both groups reported high levels of emotional distress. As primary care providers, nurses should be alert to the high levels of emotional distress and health risk behaviours among all patients. This exploratory study highlights these dimensions in mothers of servicemen. This study is the first of mothers of sons serving in the military. While the focus is on mothers of sons serving in the US military, their experience is likely not unique. Mothers of military service members all over the world send their children off to war and wait for their safe return.
