Retrospective studies of military personnel and survivors of community disasters suggest a link between traumatic exposure and substance use. This is the first study to investigate this association prospectively in a military population. A representative cohort of members of the UK Armed Forces was recruited into a longitudinal study, with 1382 people surveyed at baseline, and 941 followed up around three years later. Alcohol and cigarette use were assessed on both occasions, and combat exposures during this time were assessed at follow-up. Alcohol consumption and the prevalence of binge-drinking increased over the course of the study. The increase in alcohol consumption was greater in those subjects who had been deployed, in particular in those who thought they might be killed (p=.010), or who experienced hostility from civilians while on deployment (p=.010). The effects of these combat exposures were strongest in those most recently deployed. In contrast, cigarette smoking declined during the three years of the study.
"Australian researchers have found however that alcohol disorders are significantly lower in their armed forces than for the general community (Mental Health in the Australian Defence Force, 2010). It is possible that, at least in part, the excessive drinking post-tour is related to time elapsing from exiting theatre, as excessive drinking was more common soon after returning from deployment (Hooper et al., 2008). "
[Show abstract][Hide abstract] 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.

"Data from the Millennium Cohort study shows military deployment is associated with smoking initiation and smoking recidivism, particularly among those with prolonged deployments, multiple deployments, or combat exposure . However the UK armed forces study which evaluated combat exposure using the same questions as the current study, did not find a relationship between the number of cigarettes smoked and combat exposure . "
[Show abstract][Hide abstract] ABSTRACT: Among military personnel alcohol consumption and binge-drinking have increased but cigarette smoking has declined in the recent past. Although there is a strong association between smoking and PTSD the association between combat exposure and smoking is not clear.
This cross sectional study was carried out among representative samples of SLN Special Forces and regular forces deployed in combat areas. Both Special Forces and regular forces were selected using simple random sampling. Only personnel who had served continuously in combat areas during the one year period prior to end of combat operations were included in the study. Females were not included in the sample. The study assessed several mental health outcomes as well as alcohol use, smoking and cannabis use. Sample was classified according to smoking habits as never smokers, past smokers (those who had smoked in the past but not within the past year) and current smokers (those smoking at least one cigarette within the past 12 months).
Sample consisted of 259 Special Forces and 412 regular navy personnel. Prevalence of current smoking was 17.9% (95% CI 14.9-20.8). Of the sample 58.4% had never smoked and 23.7% were past smokers. Prevalence of current smoking was significantly higher among Special Forces personnel compared to regular forces. (OR 1.90 (95% CI 1.20-3.02). Personnel aged ≥35 years had the lowest prevalence of smoking (14.0%). Commissioned officers had a lower prevalence (12.1%) than non commissioned officers or other ranks. After adjustment for demographic variables and service type there was significant association between smoking and combat experiences of seeing dead or wounded [OR 1.79 (95%CI 1.08-2.9)], handling dead bodies [OR 2.47(95%CI 1.6-3.81)], coming under small arms fire [OR 2.01(95%CI 1.28-3.15)] and coming under mortar, missile and artillery fire [OR 2.02(95%CI 1.29-3.17)]. There was significant association between the number of risk events and current smoking [OR 1.22 (95%CI1.11-1.35)].
There was significant association between current smoking and combat experiences. Current smoking was strongly associated with current alcohol use. Prevalence of current smoking was less among military personnel than in the general population. Prevalence of smoking was significantly higher among Special Forces personnel.
"Additionally, some literature suggests that underlying genetic vulnerability modifies the risk of comorbid psychiatric disorders after exposure to traumatic events, including combat (Kilpatrick et al., 2007; Koenen et al., 2003). Although recent studies have begun to elucidate how specific combat experiences increase the risk of both mental illness and alcohol abuse following deployment (Browne et al., 2008; Hoge et al., 2006; Hooper et al., 2008; Wilk et al., 2010), more research is required to determine whether these exposures constitute a common etiologic pathway that drives both substance use and psychiatric conditions in soldiers of the National Guard. There are several other possible explanations for the observed associations between peri-/post-deployment alcohol abuse and coincident psychiatric problems. "
[Show abstract][Hide abstract] ABSTRACT: Although alcohol problems are common in military personnel, data examining the relationship between psychiatric conditions and alcohol abuse occurring de novo peri-/post-deployment are limited. We examined whether pre-existing or coincident depression and post-traumatic stress disorder (PTSD) predicted new onset peri-/post-deployment alcohol abuse among Ohio Army National Guard (OHARNG) soldiers.
We analyzed data from a sample of OHARNG who enlisted between June 2008 and February 2009. Participants who had ever been deployed and who did not report an alcohol abuse disorder prior to deployment were eligible. Participants completed interviews assessing alcohol abuse, depression, PTSD, and the timing of onset of these conditions. Logistic regression was used to determine the correlates of peri-/post-deployment alcohol abuse.
Of 963 participants, 113 (11.7%) screened positive for peri-/post-deployment alcohol abuse, of whom 35 (34.0%) and 23 (32.9%) also reported peri-/post-deployment depression and PTSD, respectively. Soldiers with coincident depression (adjusted odds ratio [AOR]=3.9, 95%CI: 2.0-7.2, p<0.01) and PTSD (AOR=2.7, 95%CI: 1.3-5.4, p<0.01) were significantly more likely to screen positive for peri-/post-deployment alcohol abuse; in contrast, soldiers reporting pre-deployment depression or PTSD were at no greater risk for this outcome. The conditional probability of peri-/post-deployment alcohol abuse was 7.0%, 16.7%, 22.6%, and 43.8% among those with no peri-/post-deployment depression or PTSD, PTSD only, depression only, and both PTSD and depression, respectively.
Coincident depression and PTSD were predictive of developing peri-/post-deployment alcohol abuse, and thus may constitute an etiologic pathway through which deployment-related exposures increase the risk of alcohol-related problems.
