The health of UK military personnel who deployed to the 2003 Iraq war: a cohort study.

BACKGROUND Concerns have been raised about the mental and physical health of UK military personnel who deployed to the 2003 war in Iraq and subsequent tours of duty in the country. METHODS We compared health outcomes in a random sample of UK armed forces personnel who were deployed to the 2003 Iraq war with those in personnel who were not deployed. Participants completed a questionnaire covering the nature of the deployment and health outcomes, which included symptoms of post-traumatic stress disorder, common mental disorders, general wellbeing, alcohol consumption, physical symptoms, and fatigue. FINDINGS The participation rate was 62.3% (n=4722) in the deployed sample, and 56.3% (n=5550) in the non-deployed sample. Differences in health outcomes between groups were slight. There was a modest increase in the number of individuals with multiple physical symptoms (odds ratio 1.33; 95% CI 1.15-1.54). No other differences between groups were noted. The effect of deployment was different for reservists compared with regulars. In regulars, only presence of multiple physical symptoms was weakly associated with deployment (1.32; 1.14-1.53), whereas for reservists deployment was associated with common mental disorders (2.47, 1.35-4.52) and fatigue (1.78; 1.09-2.91). There was no evidence that later deployments, which were associated with escalating insurgency and UK casualties, were associated with poorer mental health outcomes. INTERPRETATION For regular personnel in the UK armed forces, deployment to the Iraq war has not, so far, been associated with significantly worse health outcomes, apart from a modest effect on multiple physical symptoms. There is evidence of a clinically and statistically significant effect on health in reservists.

Mental health screening in armed forces before the Iraq war and prevention of subsequent psychological morbidity: follow-up study

Objective To assess whether screening for mental disorder before the start of the 2003 Iraq war would have predicted subsequent mental disorders. Design Longitudinal cohort study of the United Kingdom armed forces. Participants 2820 of 2873 personnel of the three services who completed an initial questionnaire in 2002 were asked to complete a second questionnaire between June 2004 and 2 March 2006. Setting Regiments, air stations, bases, ships, and homes for those who had left the services. Main outcome measures Positive and negative likelihood ratios, and positive and negative predictive value of first assessment compared with assessment two to three years later of post-traumatic stress disorder, general health questionnaire, physical symptoms, self perception of health, and alcohol misuse for the entire group and for those deployed to the Iraq war. Results The response rate to the follow-up questionnaire was 69%, adjusted for return to senders. The positive likelihood ratio of post-traumatic stress disorder was high (13.1, 95% confidence interval 7.2 to 23.8), but the negative likelihood ratio was close to 1 (0.78, 0.67 to 0.91). The positive predictive values were low because of the low prevalence of post-traumatic stress disorder in the period before the Iraq war. The positive likelihood ratios for the other psychological assessments varied between 2.7 and 5.6, and the negative likelihood ratios were slightly lower than for post-traumatic stress disorder, indicating that these were not good candidates for screening. Results were the same for the analyses restricted to those who were deployed. Conclusions Screening for common mental disorders before deployment in this cohort would not have reduced subsequent morbidity or predicted post-traumatic stress disorder, but this may change if there is a considerable increase in the prevalence of the disorder.

How do experiences in Iraq affect alcohol use among male UK armed forces personnel

Objectives: This paper reports on a statistically significant association between alcohol use and deployment to the 2003 Iraq War. It assesses the occupational factors and deployment experiences associated with heavy drinking in regular UK servicemen deployed to Iraq in the first phase of the 2003 Iraq War (Operation TELIC 1, the military codename for the conflict in Iraq). Methods: A random representative sample of 3578 regular male UK Armed Forces personnel who were deployed to Iraq during Operation TELIC 1 participated in a cross-sectional postal questionnaire study (response rate 61%). Participants completed a questionnaire, between June 2004 and March 2006 (ie, after deployment), about their health, including a measure of alcohol use (Alcohol Use Disorders Identification Test, AUDIT) and questions about their experiences on deployment to Iraq. Heavy drinkers were identified as those scoring 16 or above on the AUDIT. Results: After adjustment for sociodemographic and military factors, and the presence of psychological distress, heavy drinkers were more likely to have had major problems at home during (odds ratio (OR) 1.33, 95% confidence interval (CI) 1.04 to 1.70) and following their deployment (OR 1.68, 95% CI 1.32 to 2.14). Being deployed with their parent unit (OR 1.28, 95% CI 1.02 to 1.61), medium to high in-theatre unit comradeship (medium: OR 1.35, 95% CI 1.04 to 1.77; high: OR 1.35, 95% CI 1.02 to 1.79) and poor unit leadership (OR 1.78, 95% CI 1.37 to 2.31) were also associated with heavy drinking. Conclusions: Deployment experiences and problems at home during and following deployment, as well as the occupational milieu of the unit, influence personnel’s risk of heavy drinking.

Uptake of screening for breast cancer in patients with mental health problems

Objectives: Mental illness is associated with physical illness and mortality from a variety of causes including cancer. There is little information on screening attendance among the mentally ill population. An audit was conducted of a breast screening service in inner London to determine uptake rates in women with mental illness. Design: Cross sectional data linkage study of the local screening register and patients of the local psychiatric units. Screening uptake rates in all patients, those with a history of multiple detentions in hospital, and those with psychosis were compared with the local reference population. Setting: Women in three inner London boroughs. Participants: Screening records for 933 psychiatric patients and 44 195 women without mental health problems aged 50 to 64 years. Main results: Overall, psychiatric patients were as likely as the reference group to attend breast screening. Patients with a history of multiple detention were significantly less likely to attend (OR = 0.40, 0.29 to 0.55; p<0.001), as were patients with a diagnosis of psychosis (OR = 0.33, 0.18 to 0.61; p<0.01). Increasing age, a history of detention in hospital, and social deprivation remained independent predictors for non-attendance. Conclusion: Women with severe mental health problems may be less likely to attend national screening programmes such as breast screening, and action should be taken to overcome the barriers to attendance.

Is there an Iraq war syndrome? Comparison of the health of UK service personnel after the Gulf and Iraq wars

BACKGROUND UK armed forces personnel who took part in the 1991 Gulf war experienced an increase in symptomatic ill health, colloquially known as Gulf war syndrome. Speculation about an Iraq war syndrome has already started. METHODS We compared the health of male regular UK armed forces personnel deployed to Iraq during the 2003 war (n=3642) with that of their colleagues who were not deployed (n=4295), and compared these findings with those from our previous survey after the 1991 war. Data were obtained by questionnaire. FINDINGS Graphs comparing frequencies of 50 non-specific symptoms in the past month in deployed and non-deployed groups did not show an increase in prevalence of symptoms equivalent to that observed after the Gulf war. For the Iraq war survey, odds ratios (ORs) for self-reported symptoms ranged from 0.8 to 1.3. Five symptoms were significantly increased, and two decreased, in deployed individuals, whereas prevalence greatly increased for all symptoms in the Gulf war study (ORs 1.9-3.9). Fatigue was not increased after the 2003 Iraq war (OR 1.08; 95% CI 0.98-1.19) but was greatly increased after the 1991 Gulf war (3.39; 3.00-3.83). Personnel deployed to the Gulf war were more likely (2.00, 1.70-2.35) than those not deployed to report their health as fair or poor; no such effect was found for the Iraq war (0.94, 0.82-1.09). INTERPRETATION Increases in common symptoms in the 2003 Iraq war group were slight, and no pattern suggestive of a new syndrome was present. We consider several explanations for these differences.

Smoking among males in the UK Armed Forces: changes over a seven year period.

OBJECTIVES We assessed socio-demographic and military factors associated with smoking among males in the UK Armed Forces; made comparisons with the general population; and, tested the hypothesis that smoking has declined in the Armed Forces. METHODS Using data from two cross-sectional studies (conducted in 1998 and 2004), we examined the patterns of smoking among regular male UK Service personnel aged 20-49 years and made comparisons with general population data from England, Scotland and Wales. RESULTS In 2004, the prevalence of smoking among military males aged 20-49 years was 30% (n=2276), compared to 33% within the general population. Among current smokers, the mean number of cigarettes smoked per day was 15 for the military and 14 for the general population. The prevalence of smoking has decreased in lower ranks between 1998 and 2004 by 5.1% in 20-24 year olds to 6.3% in 35-49 year olds. These decreases are similar to those seen within those in the routine, manual or intermediate socio-economic group. CONCLUSIONS Smoking among males in the UK military is associated with similar factors to those in the general population. As these factors are clustered in younger personnel, policies to decrease smoking should be targeted at younger recruits.
