Summary
Ageing and the growing obesity epidemic are two contributing factors to cognitive decline. This research will identify dietary patterns that are associated with better cognitive function using data from individuals in Australia, the United States and Europe, and be used to guide dietary strategies to prevent or slow cognitive decline in at-risk individuals. Delaying or preventing the onset of dementia will save the Australian health care system billions of dollars.
Metabolically Healthy Obesity: An Investigation Of Its Predictors And Outcomes Across The Lifecourse

Summary
Obesity is a major health problem with 30% of Australian adults being obese. Despite attention on the health impact of obesity and programs to reduce weight, maintaining weight loss is difficult. However, not all obese individuals are at higher risk of disease. This research will examine the behavioural and genetic factors of these individuals and their risk of disease. The findings may inform new treatments for obesity that focus less on weight loss and more on health.

Summary
Schistosomiasis and soil-transmitted helminths are major parasitic infections in Asia, causing anaemia, poor growth and poor school performance and death in some chronic schistosomiasis cases. We will use maps to demonstrate the geographic distribution of these parasites in the Philippines. We will estimate the impact and costs and benefits of parasite control programmes. This research will help plan more efficient parasite control and reduce the impact of these infections in the Philippines.

Summary
This research will develop a spatial simulation model to predict the spread of pandemic influenza within Australia. The resulting software program will be readily usable by disease managers, both during and prior to an outbreak, to predict the effect of various containment measures on the size, rate and location of disease spread, through a city, state or the nation.

The resulting software program will be readily usable by disease managers, both during and prior to an outbreak, to predict the effect of various containment measures on the size, rate and location of disease spread, through a city, state or the nation. Deployed in _real time� after an outbreak has started in Australia, it will be used to predict infection spread and the containment effect of a range of interventions. The model would use data obtained during initial stages of the outbreak to refine the model, so allowing accuracy in daily spread prediction; similar use of spatial models occurred during the 2001 Foot and Mouth Disease (FMD) outbreak in the UK. In a pre-pandemic period the simulation model will be available to predict the containment effect of a range of response measures, such as travel restrictions, workplace and school closures, vaccination and antiviral usage. Specifically, this project will apply the simulation model to determine optimal use of limited resources such as the _when and where� targeting of antiviral drugs and initial supplies of vaccine.Read moreRead less
Case-Control Study Of Genetic And Environmental Risk Factors For Pancreatic Carcinoma

Summary
Pancreatic carcinoma is the fourth most common cause of cancer death in developed countries, and is approximately sixty percent more common in men than in women. In Australia approximately 1800 people are diagnosed with pancreatic cancer each year and there are a similar number of deaths. The five-year survival is less than five percent, and the majority of patients die within the first year. Surgery is frequently not possible due to the advanced stage of disease at diagnosis, and chemotherapy i ....Pancreatic carcinoma is the fourth most common cause of cancer death in developed countries, and is approximately sixty percent more common in men than in women. In Australia approximately 1800 people are diagnosed with pancreatic cancer each year and there are a similar number of deaths. The five-year survival is less than five percent, and the majority of patients die within the first year. Surgery is frequently not possible due to the advanced stage of disease at diagnosis, and chemotherapy is largely ineffective. A better understanding of the causes of pancreatic cancer is essential in order to develop strategies to prevent this lethal cancer. Currently the causes of pancreatic cancer are poorly understood. Family history and smoking probably account for approximately 30% of cases, but for the remainder the cause is unknown. This study will assess a new hypothesis, namely that too much acid in the stomach possibly caused by infection with a bacterial organism, could increase the risk of pancreatic cancer. We will include people who are diagnosed with cancer of the pancreas (cases), and match these to people selected from the electoral roll who have not ever been diagnosed with pancreatic cancer (controls). Participants will be asked a series of detailed questions about their diet, smoking, occupation and medical history. We will collect blood to look for antibodies to the bacteria and to examine specific genes, and we will compare all these factors in cases and controls. This is one of the first large studies of pancreatic cancer in Australia and we will take an integrated approach to examining interactions between genetics and exposure to environmental factors.Read moreRead less

With increasing population levels of overweight, governments are increasingly advocating public health measures aimed at increasing physical activity levels or otherwise decreasing weight. There has been much research concerning which of these factors is the key prognostic factor for adverse health outcomes, but an ongoing lack of clarity of research findings has led to uncertainty as to the direction of recommendations for preventive health strategies and population lifestyle changes. In addition, the risks of overweight, in particular, have been accused of being exaggerated in both the scientific and lay literature. This is often due to the difficulty of dealing appropriately with time varying confounders which are also intermediate factors (such as hypertension). To date, no studies have performed careful longitudinal modelling of the joint effects of physical inactivity and overweight on cardiovascular events and diabetes while taking into account the effects of factors, such as hypertension or atherosclerosis, that influence both physical activity and overweight as well as disease, and simultaneously are consequences of these risk factors. Standard statistical methods are known to produce biased estimates in these situations but we will apply more recently developed statistical techniques to provide much improved estimation of these effects. After the statistical modelling stage, we will model the burden of diabetes, cardiovascular disease and mortality associated with given levels of overweight and physical inactivity. These will be combined with population levels of overweight and inactivity to identify the fraction of the current and future burden of disease attributable to these risk factors.Read moreRead less
Implications Of The Increasing Duration Of Life Spent With Obesity For Population Health

Summary
As the prevalence of obesity at younger ages increases, people are living longer with obesity. We have recently shown that this has an increased risk of mortality and diabetes. In this project we will look at the extent to which an increasing length of time lived with obesity is also associated with increased risks of hypertension, heart disease, cancer, arthritis and disability. We will also look at the effect of this increasing duration on the overall health of Australian adults.

Summary
Infectious disease outbreaks are driven by complex interactions between humans, animals, vectors, and the environment. Globally, outbreaks have been increasing in frequency and magnitude, e.g. Ebola and SARS. There is an urgent need to improve public health intelligence by accurately identifying the causes, timing, and hotspots. This project will develop advanced modelling strategies for improving our understanding of outbreaks, and optimise public health interventions to protect human health.
