Unveiling binge drinking trends and triggers among army personnel: A cross sectional study

Abstract: BACKGROUND: Military populations are known to have higher prevalence and heavier alcohol use compared to the general population globally. This has serious negative implications to the military. The objective of this study was to describe the prevalence, patterns and associated factors of binge drinking among male military personnel in the Sri Lanka Army. METHODS: A cross sectional study was conducted among 1337 male Army personnel in active service using multistage sampling. A self-administered questionnaire and the interviewer-administered Alcohol Use Disorders Identification Test which is a 10-item screening tool were used. Prevalence of binge drinking was summarised as a proportion with 95% Confidence Intervals (CI). Age specific prevalence rates and the age standardized prevalence rate of binge drinking were calculated. The standard measure of one unit of alcohol being equivalent to 10 g of pure alcohol was used as a reference to calculate the units of alcohol consumption. Binary logistic regression analysis was used to determine the factors associated with binge drinking. RESULTS: The overall prevalence of binge drinking was 51.2% (95% CI 48.5%-54.0%). The age standardized prevalence of binge drinking was 28.3%. The majority binge drank once a month (50.4%). Those engaged in binge drinking used 5.6 median units of alcohol on a typical day, 84% consumed arrack, 69.3% have ever thought or attempted to quit and median age of first alcohol consumption was 18 years. When controlled for confounding, those who had mental distress (AOR 2.46, 95% CI=1.72-3.53), had sex with a commercial sex worker (AOR 1.92, 95% CI=1.21-3.06), ever smoking (AOR 1.69, 95% CI=1.27-2.25), had serious consequences (AOR 1.58, 95% CI=1.13-2.20), currently used cannabis (AOR 1.39, 95% CI=1.02-1.89) and had combat exposure (AOR 1.37, 95% CI 1.00-1.87) had a higher likelihood of binge drinking. CONCLUSIONS: The high prevalence of binge drinking warrants immediate advocacy to the highest level of command of the Sri Lanka Army for support to implement sustainable evidence-based alcohol prevention programmes.

    It's better to run towards the fire: The experience of reserve duty for reservists with PTSD prior to re-enlistment

    Abstract: Background: Little research exists delineating the experience of serving in the military with PTSD despite longitudinal studies indicating that a small percentage of deployed combat soldiers have PTSD prior to deployment. Following a mass re-enlistment of reserves, during the Iron Swords war, the current qualitative study aimed to describe the experience of fifteen reservists with pre-existing PTSD and explore the clinical difficulty or utility of their service. Methods: Reservists were interviewed by trained clinicians and interviews were transcribed and analyzed using a grounded descriptive phenomenological approach. Results: Findings demonstrated a key theme of a reparative experience in addition to the differentiation between functioning on the domestic and military front and the differentiation between the fantasy of success versus the reality of re-enlistment with PTSD. The experience of re-enlistment as a reservist compared to the original PTSDinducing service was described in terms of enhanced capability, a greater awareness of emotional needs by seniors and the establishment in general, enhanced choice (including that to re-enlist) and the utility of PTSD symptoms such as hyperawareness, on the battlefield compared to the futility at home. Conclusions: The study highlighted the unknown nature of repeated duty and the potential for increased difficulty of transition between military and domestic spheres while acknowledging the potential for a positive experience of re-enlistment with PTSD. The findings reinforced the need for clear clinical guidelines within the military and importance of monitoring for risk of deterioration of symptoms both on the battlefield and following discharge when enlisting those with PTSD.
