The project has two parts. One is concerned with checking that changes in medical and surgical treatment of coronary artery disease have been followed by improvements in survival of affected patients. The second will use data on changes in the Australian population, changes in the frequency of heart disease and changes in treatments for heart disease to predict how many coronary operations will be needed in Australia over the next decade. This is a vital step in planning hospital services for patients with coronary disease.Read moreRead less

Summary
Chronic diseases such as coronary heart disease, breast cancer, prostate cancer and non-insulin dependent diabetes are responsible for a significant burden of ill-health in society. Studies of familial aggregation are important in determining the relative magnitude of genetic and lifestyle-environment factors associated with chronic diseases, and in identifying individuals and families at high risk, even in the absence of conventional risk factors.

Studies of familial aggregation are important in determining the relative magnitude of genetic and lifestyle-environment factors associated with chronic diseases, and in identifying individuals and families at high risk, even in the absence of conventional risk factors. The findings have implications for health promotion in the general population and disease prevention in those identified to be at high risk. An outstanding characteristics of these studies is that many participants had an event at some unknown time before the entry. This project aims at adapting current methods to properly account for events before entry and to provide estimates of familial aggregation between parents, between children and between parents and children in the same model. Furthermore, it provides freely available software for proper familial analyses which have not had any feasible numerical methods (or software). In addition, it provides estimates of familial aggregation of coronary heart disease in Busselton families which has longer follow-up than most other studies. This project is very cost effective as the Busselton Health Study consists of a series of cross-sectional surveys since 1968 and currently has hospital morbidity and death follow-up from medical record linkage until the end of 1997.Read moreRead less

Summary
Cardiovascular diseases account for about half of all deaths and for considerable use of health care resources. While several risk factors for cardiovascular disease, such as smoking, high blood pressure, high cholesterol, overweight and diabetes, are well-established, these do not fully explain all cardiovascular disease. In recent years, some new potential risk factors for cardiovascular disease have been identified.

While several risk factors for cardiovascular disease, such as smoking, high blood pressure, high cholesterol, overweight and diabetes, are well-established, these do not fully explain all cardiovascular disease. In recent years, some new potential risk factors for cardiovascular disease have been identified. This study aims to examine these new risk factors in an Australian population. Using information collected by the Busselton Health Surveys over the last 20 years, we aim to determine whether people who had these risk factors in 1978 were more likely to develop cardiovascular disease over the following years. Since all the information needed has already been collected in the course of earlier health surveys, this study will be particularly cost-effective. We expect that results from this study will increase our understanding of the causes of cardiovascular disease, and may suggest some simple tests to help identify those people who may be at higher risk of heart disease and most likely to benefit from intervention.Read moreRead less

Throughout Asia and the Pacific, cardiovascular diseases are now a leading cause of death and disability.

However, most information about the causes of these diseases comes from studies conducted in North America and Europe, and there are few data available from the Asia Pacific region. Because patterns of cardiovascular diseases and levels of risk factors are very different in the West and East, it is possible that important differences exist in the relative contribution of different factors to disease occurrence in different regions. For example, an earlier project, from which the current study evolved, demonstrated that the association of blood pressure with stroke was about two times steeper in China and Japan than in the West. The present project has been initiated to further investigate the causes of common cardiovascular diseases in populations of the Asia Pacific region. It will involve more than 40 studies conducted in at least 9 countries from the region. These studies include more than 500,000 individuals followed for an average of 8-9 years. Data from 30 studies involving 450,000 individuals has already been provided to the applicants. Analyses will be conducted to provide region-, age-and sex-specific estimates of the effects various risk factors on several types of cardiovascular diseases. The risk factors of interest include: blood pressure, total cholesterol and its subfractions, triglycerides, diabetes, obesity, alcohol consumption, occupation and education. In addition to providing more precise estimates of the effects of established risk factors such as blood pressure, this project will, provide new data on several other risk factors not well investigated in this region. The results should be of importance in determining priorities for cardiovascular disease prevention. They should also be of relevance for predicting changes in the extent of the cardiovascular disease epidemics facing countries in the region.Read moreRead less

The outlook for these patients varies dramatically with the depth of invasion of melanoma ....AIMS This study will assess how melanoma is diagnosed in Queensland, and if improvements can be made. It will assess if skin screening gives earlier diagnosis of some melanomas, and also if it leads to the diagnosis of some thin melanomas which would not progress if left alone. SIGNIFICANCE Melanoma is the most common invasive cancer in Queensland, with some 1,963 people diagnosed annually with the disease. The outlook for these patients varies dramatically with the depth of invasion of melanoma. Melanoma diagnosed and treated when very thin has an excellent long-term outcome, whereas the outcome for deeply invasive melanoma is much less favourable. Improvements to diagnosis are currently our best hope of reducing deaths and serious distress from this disease. This will be the largest study in the world of the process of diagnosis of melanoma: information on how melanoma presents, and the time between presentation and diagnosis will be compared between thin and deeply invasive melanoma. Results may indicate areas for improvement in education or health services. The use of screening, either by individuals themselves or by health professionals, has the potential to achieve early diagnosis. However, there is currently no good information on whether screening is actually effective. This study will assess the impact of self-screening and doctor screening on the depth of invasion of melanoma at presentation, and ultimately on the likelihood of dying from melanoma. The study will also assess the potential impact of screening on the over-diagnosis of lesions which while labeled as melanoma, may in fact be biologically non-progressive. This is an important issue of current concern internationally. This study will be one of only two studies in the world currently addressing this issue. This project is directly relevant to the early detection and optimum management of the most common invasive cancer in Queensland, and will have relevance internationally.Read moreRead less

Summary
This project investigates whether the air pollution that was caused by the 2006-2007 Victorian bushfires, had an effect on the health of people living in Melbourne. Cardiovascular effects will be studied by looking at hospital admissions, out-of-hospital heart attacks and the associated death toll. As it is the expectation that bushfires will increase in the future it is important to determine the impact this may have. This research will inform appropriate public health strategies.

Summary
Maternal depression following childbirth is a significant public health issue. Previous Victorian research has found that 15-17% of women experience depression 6-9 months after birth, and of those depressed then, 30% are likely still to be depressed or depressed again two years after the birth. In 1998 16 Victorian municipalities began participating in the first ever community randomised trial of prevention and early intervention in depression - PRISM (Program of Resources, Information and Suppo ....Maternal depression following childbirth is a significant public health issue. Previous Victorian research has found that 15-17% of women experience depression 6-9 months after birth, and of those depressed then, 30% are likely still to be depressed or depressed again two years after the birth. In 1998 16 Victorian municipalities began participating in the first ever community randomised trial of prevention and early intervention in depression - PRISM (Program of Resources, Information and Support for Mothers). PRISM involves eight areas participating in a range of primary care and community based strategies designed to mobilise appropriate community support for mothers and children with a view to reducing maternal depression and improving maternal physical health and recovery after birth. The other eight areas are participating as comparison communities. Evaluation in PRISM is assessing major health outcomes for mothers and wider community benefits (flow-on effects) of the intervention program. Process and impact evaluation has also been undertaken to document and assess the different program elements and enhance the reproducibility of the program if successful. All women giving birth in the 16 areas are currently being surveyed six months after birth (from August 2000-February 2002). Within PRISM it is now proposed to follow-up women again two years after birth, to assess the impact of the intervention program on: *recovery from depression among the group of mothers in both intervention and comparison areas who were depressed six months after birth; and *the overall prevalence of depression and physical ill-health in all mothers. This follow-up study has the capacity to provide infromation on the poorly documented natural history of maternal depression from birth through the next two years in a large sample, including both urban and rural residents.Read moreRead less
SES And Injury In Children: A Cohort Study To Identify And Measure The Effects Of Preventable Mediating Factors

Funding Amount
$360,505.00
Summary
While changing an individual or group SES is at best a long term and challenging social objective, proximal risk factors for injury can be more readily modified. Once the proximal risk factor differential across SES groups has been adequately delineated, then the possibility arises for targeted public health intervention to redress the SES differential in the incidence of injury. The sophistication of the proposed modeling will result in a good assessment of the best point to target.
