Summary
Evidence has been accumulating for some time indicates that an individual's life expectancy is affected by their socioeconomic circumstances. In general, it appears that people with higher incomes tend to live longer. More recently, some evidence has suggested that life expectancy is affected not only by a person's income level but also by their relative position in the income distribution. Some studies have found that, when income is more unequally distributed, mortality rates tend to be higher ....Evidence has been accumulating for some time indicates that an individual's life expectancy is affected by their socioeconomic circumstances. In general, it appears that people with higher incomes tend to live longer. More recently, some evidence has suggested that life expectancy is affected not only by a person's income level but also by their relative position in the income distribution. Some studies have found that, when income is more unequally distributed, mortality rates tend to be higher and life expectancy lower. Several explanations for this association have been advanced. One is that the association is a statistical artifact. Another is social-psychological, arguing that a sense of relative deprivation and social exclusion increases susceptibility to a variety of conditions. A third explanation is couched in terms of social capital, a term that refers to various forms of participation in voluntary organisations which strengthen community life. A fourth argues that it is material deprivation that is the underlying cause - income inequality is found in communities characterised by lower levels of provision of social infrastructure such as schools, libraries, and health services. The main purpose of this research project is to investigate the association between morbidity, mortality, income, and income inequality in Australia. The project will attempt to find which of the several explanations just discussed are supported by Australian evidence. The results of the project will enhance our understanding of the relationship between socioeconomic status and health, and will have implications for the design of different policies aimed at ameliorating the effects of income inequality on health.Read moreRead less

Summary
Socioeconomically disadvantaged groups have the highest rates of death and ill-health for diet-related diseases (eg. coronary heart disease, some cancers). Our understanding of the dietary practices which may contribute to these outcomes, however, is limited.

Our understanding of the dietary practices which may contribute to these outcomes, however, is limited. This project focuses on this issue by examining the relationship between socioeconomic status and food purchasing behaviour. Studies investigating this relationship have found that disadvantaged social groups are least likely to purchase foods which are important for long-term health. The reasons for this association, however, remain unclear. Research into the general determinants of food purchasing behaviour shows that food choices are influenced by the intra-personal characteristics of individuals (eg. knowledge and beliefs), interactions between individuals sharing the same context (eg. relations between parents and children), economic and material factors (eg. income, access to a car) and features of the wider physical environment (eg. availability of healthy food and public transport). What is clear from this evidence, is that food choice is influenced by factors which operate at multiple levels. This project aims to collect data simultaneously from each level, and determine whether (and to what extent) factors operating at each level differentially influence the food purchasing behaviours of socioeconomic groups. This study (i) will contribute to our understanding of why socioeconomic groups differ in their health status, (ii) is consistent with the goals and recommendations of numerous government reports, each of which calls for a a reduction in health inequalities, (iii) represents a methodological advance on previous research, and (iv) will generate the information necessary to develop innovative and appropriately targeted health promotion and health education campaigns.Read moreRead less

Summary
Regular physical activity offers many health benefits, whereas inadequate activity is a leading cause of premature death and disability and a major contributor to the increasing prevalence of overweight and obesity. Socioeconomically disadvantaged groups are least likely to be physically active, and they experience higher rates of death and morbidity for conditions directly linked to inactivity.

Socioeconomically disadvantaged groups are least likely to be physically active, and they experience higher rates of death and morbidity for conditions directly linked to inactivity. Currently, our understanding of why socioeconomic groups differ in their physical activity is limited, and very little research has investigated this issue. This study will investigate why socioeconomic groups differ in their physical activity, by examining the influence of neighbourhood and individual-level factors. Neighbourhood factors include people's access to recreational facilities such as swimming pools, tennis courts, golf clubs, gyms, local parks, walking and bicycle paths; prices for entry to recreational facilities and opening hours; physical characteristics of the neighbourhood including public transport, presence of footpaths and street lighting, speed limits on local streets, availability of local services such as shops and schools, and; aesthetic characteristics, such as the presence and size of parks and green spaces, and traffic density. Individual factors include personal enjoyment, knowledge, confidence, type of occupation and hours worked, family responsibilities, age, health status, and whether other family member or friends engage in physical activity. A major aim of the study is to determine whether environmental or individual factors are more important in influencing participation in physical activity. The study will produce new knowledge to inform future public health strategies directed at increasing physical activity among socioeconomically disadvantaged groups, and these will have the potential to reduce socioeconomic health inequalities, as well as contribute to an overall reduction of the disease burden attributable to chronic conditions.Read moreRead less
Pathways To Mental Health And Obesity In Young Adults: A Longitudinal Study

Summary
While the health of the population has been gradually improving, there are some health problems which are increasing. The mental health of young people is one such area. Based on data relating to youth suicide, substance abuse, cigarette smoking by females and behavioural or mental health problems in the young, there has been evidence of a marked increase in some important health problems faced by the young.

The mental health of young people is one such area. Based on data relating to youth suicide, substance abuse, cigarette smoking by females and behavioural or mental health problems in the young, there has been evidence of a marked increase in some important health problems faced by the young. Little is known about the causes of these problems and even less is known about the reasons for the increase. Based on the available evidence, 20-25% of young persons manifest a mental health problem. A second area of marked health deterioration concerns youth (and adult) obesity. Existing research points to the accumulation of cardiovascular risk factors associated with obesity from a very early age. Over 10% of youth are obese and a substantially higher proportion are overweight. There is evidence that the rate of obesity has been substantially increasing. Again little is known about the factors that contribute to obesity or the causes of the increase in the rates of obesity in the population. This proposal is for a 21-year follow-up of a sample of youth first enrolled when their mothers attended for their first obstetrical visit. Using a substantial body of existing data, we propose to examine the changes in levels of mental health and obesity and to identify the factors which contribute to these changes. This study involves the largest Australian cohort ever assembled for such research. The main questions asked in this study concern the impact of the mother's social and economic circumstances, her physical health and well-being, her use of addictive substances (including alcohol, cigarettes, illicit drugs) on the youth's health. We will also examine the association between early indicators of mental health and well-being and subsequent youth health and development.Read moreRead less

While previous studies have documented socioeconomic gradients in oral health, few have sought to explain the reasons underlying those inequalities. By taking advantage of two existing datasets of child oral health in Australia, collected in 1992 and 2002, we will be able to quantify change in socioeconomic inequalities in oral health, and identify population-wide exposures to preventive practices and social circumstances that may have contributed to that change.Read moreRead less
SES And Injury In Children: A Cohort Study To Identify And Measure The Effects Of Preventable Mediating Factors

Funding Amount

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.

The first objective will involve establishing teams of clinicians and researchers who will work together to develop and validate lists of MBS and PBS item numbers that are indicative of specified chronic diseases. This information will then be used to identify patients with these conditions from the MBS and PBS databases during the period 1990-2003 and this method of case ascertainment will be compared with the use of the Hospital morbidity data system alone. Once groups of patients have been identified, their utilisation rates of MBS, PBS and hospital services will be calculated. The effect of social and geographical indices on the occurrence of disease and the utilisation of services will also be studied. Trends over time in health status and health service utilisation are vital to the evidence-based planning and evaluation of health services and to the provision of an equitable and accessible health service which is based on the needs of the community. The work will represent the first time that the utilisation of Australian MBS and PBS itemised services is measured in diagnostically defined groups of patients with chronic diseases.Read moreRead less

The number of women incarcerated within Australian prisons has doubled over the last ten years. Prisons contain large numbers of women from Indigenous backgrounds, women with a mental illness, women with violent partners and women with substance abuse problems. As such they constitute one of the most disadvantaged groups within Australian society and their children are unlikely to experience a healthy start to life.

Prisons contain large numbers of women from Indigenous backgrounds, women with a mental illness, women with violent partners and women with substance abuse problems. As such they constitute one of the most disadvantaged groups within Australian society and their children are unlikely to experience a healthy start to life. At any one time around 5-10% of women inside Australian prisons are pregnant. There has been no Australian research into the effect incarceration has upon pregnant women or their babies. Some believe that women who are incarcerated during their pregnancy may have better outcomes as they are outside their normal milieu with restricted access to alcohol and illicit drugs and separated from abusive partners. Others argue that the stress of incarceration and separation from family and friends could result in poorer pregnancy outcomes. This study will investigate whether being imprisoned while pregnant results in better or worse pregnancy and birth outcomes for Australian women and their babies.Read moreRead less
