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
A Prospective Study Of The Effects Of Early Life Growth On Adult Mammographic Density

Summary
It is now well-known that a woman's breast density, as measured by a breast scan, is a predictor of her future risk of breast cancer. It is also known that women who are heavier as babies and grow rapidly before age 7 are more likely to develop breast cancer in adult life. The effects were strongest in women who had early puberty. It has been suggested that there are critical points in early life growth that contribute to higher breast density in middle-age. Population-based surveys with early l ....It is now well-known that a woman's breast density, as measured by a breast scan, is a predictor of her future risk of breast cancer. It is also known that women who are heavier as babies and grow rapidly before age 7 are more likely to develop breast cancer in adult life. The effects were strongest in women who had early puberty. It has been suggested that there are critical points in early life growth that contribute to higher breast density in middle-age. Population-based surveys with early life growth data on large numbers of women that span birth to adulthood are necessary to estimate accurately the association between early life growth and breast density in middle age. Few such studies exist; Tasmanian Asthma Study is one of them. In 1968, all 4,194 female Tasmanian school children born in 1961 were surveyed and height and weight measured. Subsequently, weight and height measurements were carried out on samples of this cohort. We are currently conducting the 37-year follow-up of the TAS and to date have traced 87% and achieved a response rate of 77% (2,850) for a postal survey. This included self-reported weight and height measurements and detailed information reproductive history and the use of hormones. Weight, height and waist to hip ratio are currently measured on 600 of these respondents. We have access to school medical records of the full cohort, which have weight and height data measured at school medical inspections throughout school years, and maternal records so far for half of the total cohort, which have information on birth weight and length, and period of gestation. Hence, TAS now provides an ideal opportunity, unique within Australia, to investigate prospectively the association between early life growth and mammographic density in middle-age women. We will measure breast density in these women now they are in their late 40s, using the Australian Mammographic Density Research Facility at The University of Melbourne.Read moreRead less
The Ovarian Cancer Prognosis And Lifestyle (OPAL) Study: Long-term Outcomes

Summary
Ovarian cancer affects 1500 women each year in Australia and 5-year survival is <45%. Affected women thus face a poor prognosis and often ask what they can do to improve this. There is no direct evidence whether a woman’s lifestyle might influence her outcomes, although data from breast cancer suggest this is possible. The OPAL Study is following 960 women with ovarian cancer to identify whether lifestyle is associated with long-term survival to provide evidence for women with this disease.

Summary
Ovarian cancer affects 1300 women each year in Australia and 5-year survival is <45%. Women with this cancer thus face a poor prognosis and many ask what they can do to improve this. There is no direct evidence whether a woman’s lifestyle might influence her outcomes, although data from breast cancer suggest this is possible. The OPAL Study will follow 1200 women with ovarian cancer to identify whether lifestyle is associated with survival to provide guidance for women with this disease.
Ovarian and endometrial cancer affect >3,200 women each year in Australia and 3 or 4 women die from these cancers every day. The overall aim of my program of research is to reduce the burden of these cancers in future generations of Australian women by increasing our understanding of (i) what causes them, (ii) how we can optimise patient management to enhance patient outcomes and (ii) how lifestyle changes might improve quality and life and survival, for women who are diagnosed with them.
Changing Heat: Direct Impacts Of Temperature On Health And Productivity - Current Risks And Climate Change Projections

Summary
We know that heatwaves kill people - some 50,000 died in the 2003 European heatwave - but little is known of the details. This project will discover those details, in three important dimensions: WHO is at risk, and where do they live; HOW are people at risk, e.g. from kidney failure; and just WHAT is it about heat that is most dangerous? We will then build mathematical models of the future risks, and explore what public health measures will best protect Australians in a warming climate.
