Abstract
Objectives: To examine whether severe Gulf War illness (SGWI) case status was associated with longitudinal multimorbidity patterns. Methods: Participants were users of the Veteran Health Administration Health Care System drawn from the Gulf War Era Cohort and Biorepository (n = 840). Longitudinal measures of multimorbidity were constructed using (1) electronic health records (Charlson Comorbidity Index; Elixhauser; and Veterans Affairs Frailty Index) from 10/1/1999 to 6/30/2023 and (2) self-reported medical conditions (Deficit Accumulation Index) since the war until the survey date. Accelerated failure time models examined SGWI case status as a predictor of time until threshold level of multimorbidity was reached, adjusted for age and sociodemographic and military characteristics. Results: Models, adjusted for covariates, revealed that (1) relative to the SWGI- group, the SGWI+ group was associated with an accelerated time for reaching each threshold and (2) the relationship between SGWI and each threshold was not moderated by age. Discussion: Findings suggest that veterans with SGWI experienced accelerated aging.

Social disparities and inequalities in healthcare access and expenditures among Iranians exposed to sulfur mustard: a national study using spatio-temporal analysis. BMC Health Serv Res 2023; 23:1406. [PMID: 38093322 PMCID: PMC10720241 DOI: 10.1186/s12913-023-10352-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Accepted: 11/20/2023] [Indexed: 12/17/2023] Open
Abstract
BACKGROUND Sulfur Mustard (SM) is a chemical warfare agent that has serious short-term and long-term effects on health. Thousands of Iranians were exposed to SM during the eight-year Iran-Iraq conflict and permanently injured while the socioeconomic imbalance in their healthcare utilization (HCU) and health expenditures remains. This study aims to describe the HCU of SM-exposed survivors in Iran from 2018 to 2021; identify high-risk areas; and apply an inequality analysis of utilization regarding the socioeconomic groups to reduce the gap by controlling crucial determinants. METHODS From Oct 2018 to June 2021, the Veterans and Martyrs Affairs Foundation (VMAF) recorded 58,888 living war survivors with eye, lung, and skin ailments. After cleaning the dataset and removing junk codes, we defined 11 HCU-related variables and predicted the HCU for the upcoming years using Bayesian spatio-temporal models. We explored the association of individual-level HCU and determinants using a Zero-inflated Poisson (ZIP) model and also investigated the provincial hotspots using Local Moran's I. RESULTS With ≥ 90% confidence, we discovered eleven HCU clusters in Iran. We discovered that the expected number of HCU 1) rises with increasing age, severity of complications in survivors' eyes and lungs, wealth index (WI), life expectancy (LE), and hospital beds ratio; and 2) decreases with growing skin complications, years of schooling (YOS), urbanization, number of hospital beds, length of stay (LOS) in bed, and bed occupancy rate (BOR). The concentration index (CInd) of HCU and associated costs in age and wealth groups were all positive, however, the signs of CInd values for HCU and total cost in YOS, urbanization, LOS, and Hospital beds ratio groups were not identical. CONCLUSIONS We observed a tendency of pro-rich inequity and also higher HCU and expenditures for the elderly population. Finally, health policies should tackle potential socioeconomic inequities to reduce HCU gaps in the SM-exposed population. Also, policymakers should allocate the resources according to the hotspots of HCU.

Abstract
PURPOSE Our objectives were to 1) understand the scope of the current mortality literature on U.S. women Vietnam War-era veterans and 2) identify major themes and knowledge gaps that might guide future research. METHODS A systematic scoping review was conducted. Electronic bibliographic databases were searched for studies published on women Vietnam War-era veterans' mortality between 1973 and 2020. Inclusion and exclusion criteria were applied, study information was charted using pre-established design parameters, and studies deemed eligible were retained for a more in-depth review. FINDINGS One hundred nineteen studies were initially identified. Of these, six were ultimately retained for critical review. External cause, all-cause, cancer, and cardiovascular mortality were prominent outcomes across studies. Although both methodology and outcomes varied by study, unifying themes emerged. Prominent themes included a) historic barriers to accurately identifying and classifying this veteran cohort, b) historic barriers to comprehensive assessment of their health and mortality risk, and c) the healthy soldier effect and its limitations. Research gaps identified in this review reflect a need to pay more attention to sex differences in mortality risk and military occupational and sex-specific health risk confounders in mortality models. CONCLUSIONS The research literature examining mortality among women Vietnam War-era veterans is circumscribed in size and scope. Questions about the roles of salient military occupational exposures and health risk factors on mortality risks and trends in this cohort remain unaddressed. These questions should be areas of focus in next steps research.

Abstract
INTRODUCTION Service members endure a number of musculoskeletal injuries (MSIs) during service (e.g., ankle sprains and chronic back pain). Musculoskeletal injuries can reduce engagement in physical activity after military service and contribute to a sedentary lifestyle that diminishes physical health and elevates the risk for psychological distress including suicide-related behaviors. Yet, little is known about barriers and facilitators to accessing care in veterans with co-occurring MSI and mental health conditions. The purpose of this study was to pilot two brief measures of barriers and facilitators to rehabilitation and mental health services in military veterans with musculoskeletal and mental health conditions. Self-report tools vary in their response formats in ways that can impact usability, data quality, and completeness. We examine two response styles (i.e., checklist vs. thermometer) for two health services (mental health and rehabilitation) to determine usability, patterns in item endorsement, and veteran preference. MATERIALS AND METHODS Barriers and facilitators informed by the Fortney Veterans Healthcare Access model were assessed by veterans (n = 31) on the newly developed 22-item, paper-and-pencil scale with separate ratings for mental health and rehabilitation services. All participants completed scales with both response styles and the order of administration was randomized (i.e., either the checklist first or the thermometer-style response first). Data also included self-reported demographics, musculoskeletal and mental health diagnoses, health-related quality of life, physical activity levels, mental health symptoms, suicide risk, and coronavirus disease of 2019 pandemic-related stress. RESULTS Veterans reported no differences in ease of use across response formats; however, 83.9% (n = 26) preferred the checklist style, with only 3.22% (n = 1) preferring the thermometer format. Checklist items also resulted in less missing data (i.e., range 0.00%-6.45%) than the thermometer-style option (i.e., range 6.45%-61.30%). On the checklist, total number of perceived barriers was low for mental health and rehabilitation services (i.e., M = 1.58 and M = 1.61, respectively). Distance to care and problems related to symptoms were the most frequently identified barriers for both services. Facilitators outnumbered barriers for mental and rehabilitation services, and nearness of the clinic/hospital was the top-rated facilitator for both. On the thermometer, the perceived strength of each mental health (M = 39.37) and rehabilitation (M = 39.81) service barrier was moderate (0-100 scale), while the average perceived strength of each mental health (M = 61.66) and rehabilitation service (M = 61.84) facilitator was higher. Associations between barrier and facilitator scores with mental and physical health indicators were small with exceptions. For instance, suicide attempt likelihood was positively correlated with rehabilitation services barriers; mental health burden was positively associated with both barriers and facilitators. CONCLUSIONS Results of this pilot comparing two measurement approaches identified actionable next steps. Brief barriers and facilitators checklists were viable for veteran ratings across type of health. The thermometer-based tool captured the perceived strength of barriers and facilitators but yielded problematic rates of missing data in its current form and was not preferred by veterans.

Abstract
The US Department of Veterans Affairs (VA) Gulf War Era Cohort and Biorepository (GWECB) is a nationally representative longitudinal cohort of US veterans who served during the 1990-1991 Gulf War era. The GWECB combines survey data, such as demographic, health behavior, and environmental exposure data; medical records; and a linked biorepository of blood specimens that can support a broad range of future research regarding health concerns unique to veterans of this era. To build this resource, the VA Cooperative Studies Program initiated a pilot study (2014-2016) to establish the GWECB and evaluate the processes required to build and maintain the resource. Participants (n = 1,275) consented to future sharing of their data and biospecimens for research purposes. Here we describe the pilot study, including recruitment and enrollment procedures, data collection and management, quality control, and challenges experienced. The GWECB data available to investigators under approved sharing mechanisms and the procedures for accessing them are extensively detailed. The study's consenting documents and a website link for the research survey are provided. Our hope is that new research drawing on the GWECB data and biospecimens will result in effective treatments and improved approaches to address the health concerns of Gulf War-era veterans.

Abstract
To understand the role of symptom attribution in treatment-seeking behaviours, survey results of 1356 veterans (age = 38-72 years) were analysed. Controlling for symptom frequency, significant relationships were found for specialist and psychological-related consultations. Those who favoured psychological explanations for symptoms were more likely to attend specialist and psychology-related consultations and filled significantly more prescriptions than people who predominantly explained symptoms by situational factors (normalisers). Veterans who favoured somatic explanations attended more general practitioner consultations than normalisers. Attributional style should be considered part of the constellation of factors influencing healthcare usage. Normalisers, the predominant group, used fewest health services and filled fewest prescriptions; this may have important implications for healthcare considering their tendency to minimise or downplay symptoms.

Abstract
BACKGROUND Amyotrophic lateral sclerosis (ALS) is considered a multifactorial, multisystem neurodegenerative disease due to an interaction between environmental and genetic factors. This systematic review aims at gathering all available evidence on the association between physical activity (PA) and the risk of ALS. METHODS Relevant literature published up to January 2015 was gathered through structured searches on Medline, The Cochrane Library, and the ISI Web of Science databases. Studies considering any type of PA as the main exposure and a diagnosis of ALS or motor neuron disease were selected. Data were extracted in standardized forms, and the quality of included studies was assessed using the Newcastle-Ottawa Scale (NOS). RESULTS Bibliographic searches yielded 3168 records. Nineteen case control studies and 7 cohort studies met the inclusion criteria, and were included in the analysis. Evidence on cumulative measures of PA as a risk factor for ALS remain inconclusive. However, cohort studies report a significantly higher number of cases of ALS in professional soccer and American football players, and a slightly increased risk of ALS in varsity athletes.

Abstract
A substantial amount of research has been conducted into the mental health of the UK military in recent years. This article summarises the results of the various studies and offers possible explanations for differences in findings between the UK and other allied nations. Post-traumatic stress disorder (PTSD) rates are perhaps surprisingly low amongst British forces, with prevalence rates of around 4% in personnel who have deployed, rising to 6% in combat troops, despite the high tempo of operations in recent years. The rates in personnel currently on operations are consistently lower than these. Explanations for the lower PTSD prevalence in British troops include variations in combat exposures, demographic differences, higher leader to enlisted soldier ratios, shorter operational tour lengths and differences in access to long-term health care between countries. Delayed-onset PTSD was recently found to be more common than previously supposed, accounting for nearly half of all PTSD cases; however, many of these had sub-syndromal PTSD predating the onset of the full disorder. Rates of common mental health disorders in UK troops are similar or higher to those of the general population, and overall operational deployments are not associated with an increase in mental health problems in UK regular forces. However, there does appear to be a correlation between both deployment and increased alcohol misuse and post-deployment violence in combat troops. Unlike for regular forces, there is an overall association between deployment and mental health problems in Reservists. There have been growing concerns regarding mild traumatic brain injury, though this appears to be low in British troops with an overall prevalence of 4.4% in comparison with 15% in the US military. The current strategies for detection and treatment of mental health problems in British forces are also described. The stance of the UK military is that psychological welfare of troops is primarily a chain of command responsibility, aided by medical advice when necessary, and to this end uses third location decompression, stress briefings, and Trauma Risk Management approaches. Outpatient treatment is provided by Field Mental Health Teams and military Departments of Community Mental Health, whilst inpatient care is given in specific NHS hospitals.

Abstract
INTRODUCTION After Operation Desert Storm which took place in Iraq from August 1990 to July 1991 involving a coalition of 35 countries and a 700,000 strong contingent of mainly American men, some associations of war veterans, the media and researchers described a new diagnostic entity: the Gulf War Syndrome (GWS). LITERATURE FINDINGS GWS seems to be a new disorder which associates a litany of functional symptoms integrating the musculoskeletal, digestive, tegumentary and neurosensory systems. The symptoms presented do not allow a syndrome already known to be considered and the aetiology of the clinical picture remains unexplained, an increasing cause for concern resulting from the extent of the phenomenon and its media coverage. It quickly appears that there is no consensus amongst the scientific community concerning a nosographic description of GWS: where can all these functional complaints arise from? Different aetiopathogenic hypotheses have been studied by the American administration who is attempting to incriminate exposure to multiple risks such as vaccines and their adjuvants, organophosphorous compounds, pyridostigmine (given to the troops for the preventive treatment of the former), impoverished uranium, and the toxic emanations from oil well fires. But despite extremely in-depth scientific investigations, 10 years after the end of the war, no objective marker of physical suffering has been retained to account for the disorders presented. It would appear that the former soldiers are in even better objective health than the civil population whereas their subjective level of health remains low. Within this symptomatic population, some authors have begun to notice that the psychological disorders appear and persist associating: asthenia, fatigability, mood decline, sleep disorders, cognitive disorders and post-traumatic stress disorder (PTSD). Within the nosological framework, does GWS cause functional disorders or somatisation? Finally, 20 years after the end of the fighting, only PTSD has been causally attributed to military deployment. CLINICAL FINDINGS Certain functional symptoms of GWS occur during the latent phase of a future reexperiencing syndrome, latent phase which is the locus of nonspecific symptoms. The psychotraumatised subject does not express himself spontaneously and waits to be invited to do so: if the social context does not allow this expression, the suffering can remain lodged in a few parts of the body. How can the inexpressible part of the trauma be recounted, particularly if the social context does not allow it? For civil society, calling into question "the somatic word" of veterans is difficult: why were they sent to face these hardships? What could we learn from these soldiers we do not wish to listen to: the horror of the war, the aggressive impulse of men, and the confrontation with death? Another obstacle to this reflection is the reference to stress as a prevalent aetiopathogenic model of the psychological trauma. A model like this, considering that PTSD is a normal reaction to an abnormal situation, finally discredits the subject and society and disempowers them by freezing them in a passive status of victim. DISCUSSION However, as GWS affects approximately a quarter of subjects deployed, it is not very likely that all these symptoms are caused by a psychotraumatic reaction. Many veterans suffering from GWS have themselves rejected the diagnosis of PTSD, arguing that they do not suffer repetition nightmares. What the veterans rightly tell us here is that the notions of stress and trauma cannot strictly be superimposed. A subject may have been intensely stressed without ever establishing traumatic flashbacks and likewise; a psychological trauma can be experienced without stress and without fear but in a moment of terror. This clarification is in line with the first criterion of the DSM-IV-TR which necessarily integrates the objective and subjective dimensions as determinants of PTSD. Yet, scientific studies relating to GWS are struggling to establish opposition or continuity links between the objective external exposure (smoke from petrol wells, impoverished uranium, biological agents, chemicals) and the share of inner emotion albeit reactive and characterised by a subjective stress. There were no lack of stress factors for the troops deployed: repeated alerts of chemical attacks, hostility of the environment with its sandstorms and venomous animals, climatic conditions making long hours of backup and static observation difficult, collecting bodies, lack of knowledge of the precise geography of their movements and uncertainty of the duration of the conflict. The military anti-nuclear-bacteriological-chemical uniform admittedly provided protective confinement, shutting out the hostile world from which the threat would come but, at the same time, this isolation increases the fear of a hypothetical risk whilst the internal perceptions are increased and can open the way to future somatisations. In a context like this, the somatic manifestations of anxiety (palpitations, sweating, paresthesia…) are willingly associated with somatised functional disorders to which can also be assigned over-interpretations of bodily feelings according to a hypochondriacal mechanism. The selective attention to somatic perceptions in the absence of mentalisations, the request for reassurance reiterated and the excessive use of the treatment system will be diagnostic indices of these symptoms caused by the stress. Rather than toxic exposure to such and such a substance, the non-specific syndrome called "Gulf War Syndrome" is the result of exposure to the eponymous operational theatre. But if the psychological and psychosomatic suffering occurring in veterans is immutable throughout history, the expression of these difficulties has specificities according to the past cultural, political and scientific context. In the example of GWS, the diffusion of the fear of a pathology resulting from chemical weapons has promoted this phenomenon. In the end, biochemical and biological weapons have not been used on a large scale but the mediatisation of this possibility has led to a deleterious… To spare the bother of a group psychological reflection, the scientific and political authorities chose to investigate the implication of environmental factors in the genesis of the disorder. At individual as well as social level, rather than accept a psychogenic origin, a common defence mechanism is to assign the suffering to an external cause. With the perspective of preventing the risk of diffusion of other unexplained syndromes, which could occur following future armed conflicts, new epidemiological diagnostic models must be defined. The media also has considerable responsibility for the diffusion of epidemic psychological reactions but at the same time, they can inform the population about certain individual or group psychopathological mechanisms. CONCLUSION The GWS exists: it is not an "imaginary illness" but a serious public health issue which has led to tens of thousands of complaints and swallowed up millions of dollars. To reply to human suffering, a new nosographic entity can spread through society taking the epidemic expression of a somatised disorder via identification, imitation and suggestion mechanisms. This possibility questions not only mental health but also the sociology and politics. It is necessary to inform the leaders and the general population of the possibility of this type of mass reaction, which can take the shape of a highly contagious complex functional syndrome.

Abstract
Over the past two decades, 12 large epidemiologic studies and 2 registries have focused on U.S. veterans of the 1990-1991 Gulf War Era. We conducted a review of these studies' research tools to identify existing gaps and overlaps of efforts to date, and to advance development of the next generation of Gulf War Era survey tools. Overall, we found that many of the studies used similar instruments. Questions regarding exposures were more similar across studies than other domains, while neurocognitive and psychological tools were the most variable. Many studies focused on self-reported survey results, with a range of validation practices. However, physical exams, biomedical assessments, and specimen storage were not common. This review suggests that while research may be able to pool data from past surveys, future surveys need to consider how their design can yield data comparable with previous surveys. Additionally, data that incorporate recent technologies in specimen and genetic analyses would greatly enhance such survey data. When combined with existing data on deployment-related exposures and post-deployment health conditions, longitudinal follow-up of existing studies within this collaborative framework could represent an important step toward improving the health of veterans.

Abstract
Suicide is an important public health problem in the demographic group that forms the bulk of military populations, namely young and middle-aged men. Suicide in the military also has special significance: certain aspects of military service can lead to serious mental disorders that increase the risk of suicidal behaviour. Moreover, military organizations have control over a broad range of factors (notably the direct delivery of mental health care) that could mitigate suicide risk. This article will review the literature on suicide risk in military organizations to answer the important question: Are military personnel at increased risk for suicide? Next, Mann et al.'s (2005) model for specific suicide preventive interventions in civilian settings will be reviewed and then expanded, with an emphasis on identifying special opportunities for suicide prevention in military organizations, including: 1) organizational interventions to mitigate work stress; 2) selection, resilience training, and risk factor reduction; 3) interventions to overcome barriers to care; and 4) systematic quality improvement efforts in mental health care. Finally, the evidence behind comprehensive suicide prevention programmes will be reviewed, with a special focus on the US Air Force's benchmark programme.

Abstract
INTRODUCTION An apparent increased risk for developing Amyotrophic Lateral Sclerosis (ALS), a multifactorial neurodegenerative disease, is considered to exist in the military population. PATIENTS AND METHODS ALS military and veteran patients were retrospectively recruited in April 2008 by searching medical data (Hippocrate) and repayment data (Erasme) of the French National Military Health Care Fund (Caisse nationale militaire de sécurité sociale, CNMSS) from de January 1991 to December 2007. RESULTS We report a series of 73 patients, 69 male and four female, average age of 52.5 years (range 27 to 72 years) with a peak of patients in the 50-59 year age class. The branch of military service was Army (n=26 patients), Air force (n=14), Navy (n=10) and State Police Force (n=22). The incidence among male active duty military personnel was stable from 2002 to 2007; it was less than the general population (1.7/100,000 per year in 2007), but higher in the 40-44 and 50-54 year age classes (1.90 and 5.07/100,000 per year in 2007 respectively). Duration of active duty was on average 31 years. CONCLUSION The retrospective nature of the data and the incomplete population with loss of retired military personnel without CNMSS affiliation are limitations of our study. Another means of collecting all cases of ALS among French military personnel and veterans would be to conduct a search in the 17 ALS centers in France with analysis by occupational activity for entire career.

Abstract
BACKGROUND This paper reports on a systematic review of the literature on the post-conflict injury-related mortality of service members who deployed to conflict zones. METHODS Literature databases, reference lists of articles, agencies, investigators, and other sources were examined to find studies comparing injury-related mortality of military veterans who had served in conflict zones with that of contemporary veterans who had not served in conflict zones. Injury-related mortality was defined as a cause of death indicated by International Classification of Diseases E-codes E800 to E999 (external causes) or subgroupings within this range of codes. RESULTS Twenty studies met the review criteria; all involved veterans serving during either the Vietnam or Persian Gulf conflict. Meta-analysis indicated that, compared with non-conflict-zone veterans, injury-related mortality was elevated for veterans serving in Vietnam (summary mortality rate ratio (SMRR) = 1.26, 95% confidence interval (95%CI) = 1.08-1.46) during 9 to 18 years of follow-up. Similarly, injury-related mortality was elevated for veterans serving in the Persian Gulf War (SMRR = 1.26, 95%CI = 1.16-1.37) during 3 to 8 years of follow-up. Much of the excess mortality among conflict-zone veterans was associated with motor vehicle events. The excess mortality decreased over time. Hypotheses to account for the excess mortality in conflict-zone veterans included post-traumatic stress, coping behaviors such as substance abuse, ill-defined diseases and symptoms, lower survivability in injury events due to conflict-zone comorbidities, altered perceptions of risk, and/or selection processes leading to the deployment of individuals who were risk-takers. CONCLUSION Further research on the etiology of the excess mortality in conflict-zone veterans is warranted to develop appropriate interventions.

Abstract
Following the 1991 Gulf War, a number of soldiers who fought there began to complain of various symptoms and disorders, the collection of which came to be known as Gulf War syndrome (GWS). A debate has raged about the nature and cause of this illness, with many suggesting that it is a psychiatric condition. GWS continues to be a contested illness, yet there is no disputing that many Gulf veterans are ill. This article considers the way in which GWS sufferers understand their illness to be physical in nature and the way in which they negotiate and resist psychological theories of their illness. Based on 14 months of ethnographic fieldwork in the United Kingdom, data for this article were collected mainly by in-depth, semistructured interviews with GWS sufferers, their family members, doctors, and scientists, as well as healthy Gulf veterans. A total of 93 informants were interviewed, including 67 UK Gulf veterans, most of whom were ill. The paper argues that despite the increasing presence of psychiatry in military discourse, GWS reveals the way that people are able to transform, negotiate and even negate its power and assumptions.

The long-term hospitalization experience following military service in the 1991 Gulf War among veterans remaining on active duty, 1994-2004. BMC Public Health 2008; 8:60.

Abstract
BACKGROUND Despite more than a decade of extensive, international efforts to characterize and understand the increased symptom and illness-reporting among veterans of the 1991 Gulf War, concern over possible long-term health effects related to this deployment continue. The purpose of this study was to describe the long-term hospitalization experience of the subset of U.S. Gulf War veterans still on active duty between 1994 and 2004. METHODS Gulf War veterans on active duty rosters as of October 1, 1994, were identified (n = 211 642) and compared with veterans who had separated from military service and then assessed for attrition at three-year intervals during a 10-year follow-up period, examining demographic and military service characteristics, Gulf War exposure variables, and hospitalization data. Cox proportional hazard modeling was used to evaluate independent predictors of all-cause hospitalization among those still on active duty and to estimate cumulative probability of hospitalization, 1994-2004, by service branch. RESULTS Members of our 1994 active duty cohort were more likely to be officers, somewhat older, and married compared with those who had separated from the military after serving in the 1991 Gulf War. Selected war-related exposures or experiences did not appear to influence separation with the exception of in-theater presence during the brief ground combat phase. Overall the top three diagnostic categories for hospitalizations were musculo-skeletal, injury and poisoning, and digestive disorders. Diseases of the circulatory system and symptoms, signs, and ill-defined conditions increased proportionately over time. In-theater hospitalization was the only significant independent predictor of long-term hospitalization risk among selected war-related exposures or experiences examined. The cumulative probability of hospitalization was highest for Army and lowest for Marines. CONCLUSION Our results were generally consistent with a previous hospitalization study of US Gulf War veterans for the period August 1991 to July 1999. Although lack of a comparison group for our study limits interpretation of overall findings, intra-cohort analyses showed no significant associations between long-term hospitalization and war-related exposures or experiences, with the exception of in-theater hospitalization, within our active duty subset of 1991 Gulf War veterans.

Abstract
After the 1991 Gulf War, veterans of the conflict from the United States, United Kingdom, Canada, Australia and other nations described chronic idiopathic symptoms that became popularly known as 'Gulf War Syndrome'. Nearly 15 years later, some 250 million dollars in United States medical research has failed to confirm a novel war-related syndrome and controversy over the existence and causes of idiopathic physical symptoms has persisted. Wartime exposures implicated as possible causes of subsequent symptoms include oil well fire smoke, infectious diseases, vaccines, chemical and biological warfare agents, depleted uranium munitions and post-traumatic stress disorder. Recent historical analyses have identified controversial idiopathic symptom syndromes associated with nearly every modern war, suggesting that war typically sets into motion interrelated physical, emotional and fiscal consequences for veterans and for society. We anticipate future controversial war syndromes and maintain that a population-based approach to care can mitigate their impact. This paper delineates essential features of the model, describes its public health and scientific underpinnings and details how several countries are trying to implement it. With troops returning from combat in Afghanistan, Iraq and elsewhere, the model is already getting put to the test.

Abstract
Explanatory models for the increased prevalence of ill health in Gulf veterans compared to those not deployed to the Gulf War 1990-1991 remain elusive. This article addresses whether multi-symptom reporting in Gulf veterans are types of medically unexplained symptoms and whether the alleged Gulf War Syndrome is best understood as a medically unexplained syndrome. A review of the epidemiological studies, overwhelmingly cross-sectional, describing ill health was conducted including those that used factor analysis to search for underlying or latent clinical constructs. The overwhelming evidence was that symptoms in Gulf veterans were either in keeping with currently defined psychiatric disorders such as depression and anxiety or were medically unexplained. The application of factor analysis methods had varied widely with a risk of over interpretation in some studies and limiting the validity of their findings. We concluded that ill health in Gulf veterans and the alleged Gulf War Syndrome is best understood within the medically unexplained symptoms and syndromes constructs. The cause of increased reporting in Gulf veterans are still not clear and requires further inquiry into the interaction between sociological factors and symptomatic distress.
