Research has shown that where you live can affect your health, with poorer areas tending to have lower levels of health. Relationships have also been found between an individual's income and their health.

Relationships have also been found between an individual's income and their health. It is not clear, however, which has the greatest influence on health difference - characteristics of the areas themselves or the type of people living in the area. Recent research has suggested that the levels of social capital (that is, links between people, the amount of voluntary community activity, and the degree to which people trust others and civic institutions) has a significant impact on health. The nature of physical environments also has an impact on peoples' lives. The study will examine how the communities in which people live influence their health and will consider both aspects of the physical and social environments of areas, and their demographic composition. The research is in three stages. The first stage involves a telephone survey of residents of metropolitan Adelaide and includes questions about social capital, area of residence and health. Existing information about areas, such as crime rates, availability of services and air and water pollution, will be collected. The second stage involves detailed case studies of four suburbs in Adelaide, two of which are more affluent than average and two of which are poorer than average. These case studies will: catalogue the facilities available; survey a random sample of residents about their health, their participation in community activities and their perceptions of their area; talk about these issues in detail with residents in each area; and assess the quality of the physical environment. In the third stage, the findings of the research will be discussed with community members and key policy makers in state and local government to determine how communities can be best structured so that they support individuals' health status.Read moreRead less
Determinants Of Area-level Inequalities In Colorectal Cancer Survival: A Multilevel Study

Funding Amount

Summary
Survival times for people diagnosed with colorectal cancer depend on where people live; typically lower in rural and socio-economically disadvantaged areas. However we know very little about why these inequalities exist. This study, the first of its type in Australia, examines how much of the survival inequalities are due to the characteristics of individuals, and how much is due to the characteristics of the area itself. This will increase our capacity to intervene to reduce these inequalities
Supply, Demand And The Distribution Of Health Services In Australia

Summary
The distribution of medical services and its impact on access and equity is widely recognised as a key concern of the Australian community. Access and equity are key indicators to the public of the performance of a health system. These concerns have led to the adoption of major policy goals under Medicare relating to equitable access to medical services for the population as a whole. Furthermore, both the community and policy makers have expressed high levels of concern over the distribution of ....The distribution of medical services and its impact on access and equity is widely recognised as a key concern of the Australian community. Access and equity are key indicators to the public of the performance of a health system. These concerns have led to the adoption of major policy goals under Medicare relating to equitable access to medical services for the population as a whole. Furthermore, both the community and policy makers have expressed high levels of concern over the distribution of medical services between sub-markets and sub-populations, in particular, in the distribution of medical services between urban and rural-remote areas. This project, for the first time, comprehensively examines the performance of Medicare in terms of access to medical services over time. Australian data sets, largely untapped by economic modelling, will be used for analysis of the relationships between the distribution of, access to, and demand and fees for Australian medical services and their impact upon mortality over time. The study will result in the first comprehensive Australian description of access and supply of different medical services by social group and by geographic location over time. Furthermore it will provide evidence on the key determinants of distribution and changes in the distribution of medical services and estimates the likely effects of policy instruments designed to address the distribution of, and access to, medical services.Read moreRead less
Empirical Ethics: Quantification Of Social Preferences For Economic Evaluation In The Health Sector

Summary
Recent studies indicate that there are significant differences between the social 'preferences'-priorities of the population and the priorities implied by health policy and embodied in health economic evaluations of the health sector. For example, members of the public give higher priority to the severely ill even when little can be done for them. The studies suggest that the public would also take into account, inter alia, a number of other factors, including prognosis, health potential and the ....Recent studies indicate that there are significant differences between the social 'preferences'-priorities of the population and the priorities implied by health policy and embodied in health economic evaluations of the health sector. For example, members of the public give higher priority to the severely ill even when little can be done for them. The studies suggest that the public would also take into account, inter alia, a number of other factors, including prognosis, health potential and the social context of the problem. They would not treat program costs in the way economic theory and practice recommends. These issues have been dramatised in the WHO's Evaluation of Health Systems (World Health Report 2000). This assigns a weight of only 0.25 to health improvement and 0.75 to issues of fairness. The proposed study will carry out three tasks. The first is to measure the importance of Australian health-related social preferences which should, potentially, be included in economic evaluation studies. Key values - parameters - including the rate of time preference and the social willingness to pay for an additional year of life will be measured precisely for immediate use. Secondly, the importance of other issues including illness severity, adaptation and prognosis will be tested to determine how these factors should be included in the economic evaluation of health programs. Finally, some general issues related to public versus private funding, egalitarianism and choice will be investigated. Results from interviews and surveys will be integrated in the Assessment of Quality of Life (AQoL) instrument and its user manual.Read moreRead less
Molecular Mechanism And Novel Activators Of Amino Acid And Calcium-sensing Class 3 G-protein Coupled Receptors
Funder
National Health and Medical Research Council
Funding Amount
$519,715.00
Summary
When we eat protein-containing foods, our bodies extract twenty different amino acids for growth and tissue regeneration. Broad-spectrum amino acid sensing receptors detect the increases in blood amino acid levels and respond by triggering the release of biochemical signals. This project will establish the molecular rules by which these receptors work and identify novel activators with potential therapeutic application for the control of growth, tissue regeneration and calcium metabolism.
Allostatic Mediators Of Socioeconomic Inequalities In Periodontitis Among Australian Adults

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
