Summary
Osteoporosis (OP) prevalence is greater for disadvantaged groups, as are less healthy lifestyles. Whilst reasons for this social gradient of OP are unknown, some biological phenomena are influenced by lifestyle factors. I will provide novel evidence about biological mechanisms underlying the social gradient of OP (epigenetics), and, using that information, engage disadvantaged communities in multidisciplinary discussions to inform effective public health interventions (community engagement).
Young Adult Social Transitions - Course Of Mental And Behavioural Disorders:The Victorian Adolescent Health Cohort Study

Summary
The paths young people follow into adulthood have changed markedly in the past three decades. Traditionally the adoption of a role as marital partner, parent and fulltime employee in the late teens and early twenties was accompanied by a diminution or 'maturing out' of health risk behaviours and emotional problems arising in adolescence.

Traditionally the adoption of a role as marital partner, parent and fulltime employee in the late teens and early twenties was accompanied by a diminution or 'maturing out' of health risk behaviours and emotional problems arising in adolescence. The social transitions into adulthood are now both delayed and in many instances changed with higher rates of cohabitation, extended teriary educational participation and part-time employment. The effect of these social changes on health risk behaviours, behavioural and mental disorders is uncertain. This proposal will undertake a further follow-up in the late twenties of a group of just under 2000 young Victorians, already studied from the age of 14 years through to the age of 24 years. This study will assess the persistence of behavioural problems such as smoking and nicotine dependence, excessive alcohol consumption and dependence, cannabis dependence, illicit drug use, risk sexual behaviour, depression and anxiety disorders. The extent to which these may be associated with successful negotiation of transitions in education, employment, relationships, parenthood and establishing an independent home will be evaluated. Alternative explanations including the severity of dependence syndrome, personality, social background and genetic risk factors will also be explored.Read moreRead less
Environmental Exposure, Human Behaviour And Respiratory Health For Children With Asthma

Funding Amount
$344,644.00
Summary
This research program will examine whether environment and behaviour work together on asthma for Australian children. Calculation on satellite-derived data will establish updated knowledge base for assessing childhood asthma in relation to residential green spaces and local climate. Significance of the research lies in the high prevalence of asthma in Australian children. Findings will help health workers allocate resources for preventing asthma attacks and provide evidence for urban planning.
Predicting The Individual Risk Of Prostate Cancer In Australian Men

Summary
Prostate cancer is a major cause of disability and death in Australian men. A number of factors, particularly age and family history, influence the risk of prostate cancer but, in contrast to breast cancer, we don't know what is the risk of developing prostate cancer over a period of time for a man with a specific set of risk factors. In fact, while a number of statistical models have been developed that use a woman's risk factor profile to estimate her risk of breast cancer, none is currently a ....Prostate cancer is a major cause of disability and death in Australian men. A number of factors, particularly age and family history, influence the risk of prostate cancer but, in contrast to breast cancer, we don't know what is the risk of developing prostate cancer over a period of time for a man with a specific set of risk factors. In fact, while a number of statistical models have been developed that use a woman's risk factor profile to estimate her risk of breast cancer, none is currently available for prostate cancer. We will apply standard statistical methods to existing data from the Australian Risk Factors for Prostate Cancer study and from the Australian Institute of Health and Welfare to develop a prostate cancer risk prediction model. We will test how factor like age, detailed family history, diet, baldness status and possibly previous PSA tests and prostate biopsies predict the risk. After developing the model, we will test the accuracy of the predictions in three ways. First, using existing data from the Australian Prostate Cancer Family Study, we will see whether the number of cases in a group of men is close to the number predicted by the model (calibration). Second, to test whether the model discriminate well men who develop prostate cancer from those who do not, we will collect family trees in a sample from the Melbourne Collaborative Cohort Study. We will use these data also to estimate the optimal cut point: men above this level of risk will be considered at high risk. Third, we will apply the model to existing data from the Dutch Prostate Cancer Family Study (DPCFS) to test whether the optimal cut point identify high-risk men and to validate the model in a non-Australian population. Finally, we will prepare a computer package that health professionals will use as decision-making tool in different scenarios including individual cancer risk assessment, design of prevention trials and targeting prevention programs to high-risk men.Read moreRead less
Heritable And Environmental Determinants Of Hospitalisation For Common Childhood Illnesses

Summary
This study will combine the unique and powerful resources of the Western Australian (WA) Data Linkage System and the WA Twin Register to disentangle the effects of genetics and the environment on the most common infectious causes of hospital admissions in children. It will highlight appropriate pathways to prevent such admissions in the future.
Do Breast Cancer Risk Factors Differ According To Underlying Genetic Susceptibility? A Pooled Analysis Of Prospective Studies From The NCI Cancer Cohort Consortium

Funding Amount
$418,581.00
Summary
We propose to use data from 23 international prospective cohort studies in the Cancer Cohort Consortium organised by the US National Cancer Institute to evaluate gene environment interactions for women who are at increased genetic risk of breast cancer. Our ultimate goal is to enhance the performance of clinical prediction tools and to develop targeted evidence-based strategies to mitigate the high absolute risk of breast cancer for women at increased genetic risk of the disease.
