Summary
Periodontal (gum) disease is a significant cause of tooth loss among adults in Australia. Bacteria (germs) that stick to teeth in dental plaque are the primary cause of gum disease. However, the amount of damage caused to the gums depends heavily on the body's immune system which fights infection throughout the body. Like many other health conditions, gum disease occurs at a higher rate in people in a relatively low socioeconomic-position (SEP) compared to people from high SEP. Studies of other ....Periodontal (gum) disease is a significant cause of tooth loss among adults in Australia. Bacteria (germs) that stick to teeth in dental plaque are the primary cause of gum disease. However, the amount of damage caused to the gums depends heavily on the body's immune system which fights infection throughout the body. Like many other health conditions, gum disease occurs at a higher rate in people in a relatively low socioeconomic-position (SEP) compared to people from high SEP. Studies of other health conditions have shown that psychosocial stress (eg. job strain, financial stress) disproportionately affects people in low SEP groups. Stress, in turn, is known to alter the body's defense mechanisms, including the immune system, contributing to higher rates of conditions such as heart disease. Researchers have used the term allostatic load to describe this failure of the body's defense system under stress. Stress has also been suggested as a contributing factor in gum disease. This study will investigate whether this sequence of events producing allostatic load also plays a role in gum disease. We will study a random sample of 610 Australian adults from the full range of SEP backgrounds. We will ask them about their experience of daily stress, and measure their levels of gum disease and dental plaque. We will also collect samples of fluid from around their gums to measure quantities of two chemicals that indicate the activity of immune defense mechanisms in the gums. We will analyze these results to determine whether stress affects the body's responses to dental plaque, and whether that response accounts for differences in levels of gum disease between SEP groups. Results from this study will pinpoint the role of common bodily defense mechanisms in the development of gum disease. These results may help to identify sources of stress that, if controlled, could reduce rates of gum disease and other conditions affected by allostatic load.Read moreRead less
A Life Course Approach To Understanding Oral Health Inequalities

Summary
Preadolescent children in Australia have lower rates of dental decay than children in almost all other economically developed countries. This is not the case for Australian adults. In fact, Australian adults aged 35-44 years have higher rates of dental decay than adults of similar age in most other economically developed countries. Not only do Australian adults have comparatively poor oral health in the lead-up to midlife, but also socioeconomic inequalities in dental decay are more pronounced a ....Preadolescent children in Australia have lower rates of dental decay than children in almost all other economically developed countries. This is not the case for Australian adults. In fact, Australian adults aged 35-44 years have higher rates of dental decay than adults of similar age in most other economically developed countries. Not only do Australian adults have comparatively poor oral health in the lead-up to midlife, but also socioeconomic inequalities in dental decay are more pronounced at this stage of life than at any other stage before or after. This study proposes to look at how oral health in young adults in shaped by their experiences across childhood, adolescence and early adulthood. This approach is based on recent evidence that points to the importance to adult health of the early years of life. In this life course perspective, the poorer health of disadvantaged individuals is seen to result from ongoing and cumulative exposure to difficult and disadvantaged circumstances across their life course. This study will trace and follow up a cohort of almost 10, 000 South Australians for whom social, familial, economic and dental behavioural information was collected in 1991-92 when these individuals were aged from five to 15 years. Now aged from 19 to 29 years, these individuals will be invited to attend a dental examination and complete a survey that will provide information on health behaviours and life circumstances shown to be important determinants of general and oral health status. One purpose will be to explore reasons for the comparatively poorer oral health status of Australian adults. A second purpose will be to investigate the magnitude of socioeconomic inequalities in oral disease at different life stages. The findings will add to the knowledge of the etiology of oral disease and open up opportunities to develop new methods of oral health promotion based on the understanding of accumulated risk across the life course.Read moreRead less
Graves’ disease is the most common cause of hyperthyroidism. It leads to long-term impairments in quality of life and has a 40% higher mortality rate compared with the general population. We know surprisingly little about the causes of Graves’ disease. One possible trigger is stressful life events; however, the relationship is yet to be proven. This study will assess whether stressful life events, specifically military deployment, are associated with Graves’ disease.

Summary
This study will track 11,000 Australian adults over 12 years to determine how many develop diabetes, obesity, kidney and heart disease. The study will develop ways to best predict those who are going to develop these conditions before they have arisen, and will explore a range of novel risk factors to better understand these conditions.
Optimising Large-scale Public Health Interventions To Control Neglected Tropical Diseases

Summary
Neglected tropical diseases (NTD) are a group of health conditions that affect the poorest of the poor, particularly in remote and rural areas. They affect the most vulnerable communities and cause substantial, chronic health harms impairing personal and social development. Several debilitating NTD are common in remote indigenous communities and Pacific islands. I propose a series of studies to investigate new strategies to control NTD in large populations where these diseases are endemic.
Development Of Early Warning Systems For Dengue Fever Based On Socio-ecological Factors

Summary
Global climate change has potentially serious effects on the transmission of dengue. An early warning system (EWS) based on socio-ecological factors will be developed to examine where and when outbreaks of dengue are likely to occur and how the future dengue control strategies and prevention efforts need to be applied and strengthened in Australia. This project will provide a platform for future research on developing and implementing an EWS for dengue in the Asia-Pacific region.
Exploiting Existing Data Sources To Improve The Prevention And Treatment Of Cardiovascular Disease

Summary
My program of research exploits several large databases to answer important issues in the prevention and treatment of cardiovascular disease (CVD), which makes a huge contribution to the burden of illness and premature mortality in Australia. An underlying aim is to provide the evidence base to facilitate improvement of the existing CVD risk assessment guidelines in Australia, for better targeting of clinical advice and treatment.
Although the major risk factors for cardiovascular diseases have been known for decades, and modern-day treatment is much advanced, the importance of these diseases persists, such that they remain the number one killer in Australia. This suggests that more can be done to correctly identify those at high and moderate risk of future disease, so as to optimize advice and medical treatment. This project will use the best evidence available to develop new methods of risk prediction and prevention.
Predicting The Impact Of Current Obesity And Diabetes Trends On Future Prevalence Of Cardiovascular Disease In Australia

Summary
Obesity and diabetes are both strong risk factors for cardiovascular disease. As their prevalence has more than doubled over the past decades we need to know the likely effect on future rates of cardiovascular disease. Here we propose to create projection models for cardiovascular disease in Australia to estimate the future impact of trends in obesity and diabetes.
