The operational tempo of the Australian Defence Force has increased over the last two decades. We examine the relationship between health of personnel and the frequency and duration of their deployment. Self-reported health measures (number of symptoms, Kessler Psychological Distress Scale, and Post Traumatic Stress Disorder Checklist) were compared for(More)
Until the mid-20th century, mortality rates were often very high during measles epidemics, particularly among previously isolated populations (e.g., islanders), refugees/internees who were forcibly crowded into camps, and military recruits. Searching for insights regarding measles mortality rates, we reviewed historical records of measles epidemics on the(More)
BACKGROUND This study assessed the extent to which alcohol consumption in a military group differed from the general population, and how alcohol affected the military group's health and social functioning. METHODS A cross sectional survey of military personnel (n = 5311) collected self-reported data on alcohol use (AUDIT scale) and general health, role(More)
PURPOSE The healthy soldier effect denotes the proposition that military populations are likely to be healthier than other populations. A systematic review was conducted which aimed to quantify the magnitude of the healthy soldier effect. METHODS Studies containing mortality rates of military personnel were identified from multiple electronic databases.(More)
The objectives of this study were to determine the prevalence of smoking, identify the effects of deployment on smoking behavior and risk factors for smoking, and determine the short-term health outcomes associated with smoking in Australian Defence Force (ADF) personnel. Participants were randomly sampled from ADF members who deployed to the Solomon(More)
BACKGROUND Understanding the risk of mortality during the 1918-1919 influenza pandemic could inform preparations for a future pandemic. METHODS Prospectively collected demographic, hospitalization, and death data from all individuals who served in the Australian Imperial Force from 1914 through 1919 in Europe and the Middle East were abstracted from(More)
BACKGROUND Death rates in military populations outside of combat are often lower than those in the general population. This study considers how this "healthy soldier effect" changes over time. METHODS Standardized mortality ratios were used to compare changes in death rates relative to the Australian population in two large studies of Australian(More)
There were multiple waves of influenza-like illness in 1918, the last of which resulted in a highly lethal pandemic killing 50 million people. It is difficult to study the initial waves of influenza-like illness in early 1918 because few deaths resulted and few morbidity records exist. Using extant military mortality records, we constructed mortality maps(More)
This paper draws on the mortality records of the French, US and UK Royal navies to reconstruct the spatiotemporal evolution of the 1918–1919 influenza pandemic in global Allied naval forces. For a total of 7658 deaths attributed to respiratory diseases (French and US navies) and all diseases (UK Royal Navy) at 514 locations worldwide, techniques of spatial(More)
