Mobility problems, falls and dementia are among the major problems affecting older Australians with significant consequent disability. Treatment of such disorders carries an estimated annual cost of around 4 billion dollars.

Summary
Childhood brain tumours are the second most common childhood cancer (~20%) after leukaemia (~35%) and are the leading cause of cancer death among children. Children who survive a brain tumour are often left with physical and mental problems as a result of treatment. This can have a significant impact on the child, family and community. Greater understanding of the causes of childhood brain tumours may lead to preventative measures.

Children who survive a brain tumour are often left with physical and mental problems as a result of treatment. This can have a significant impact on the child, family and community. Greater understanding of the causes of childhood brain tumours may lead to preventative measures. Most children with brain tumours are very young, suggesting that factors to which parents are exposed may affect future children. For this reason, it is important to study the parents as well as the child. This study will investigate environmental exposures known to be harmful, such as parental cigarette smoking and exposure to pesticides and other chemicals. Such exposures are also thought to increase the risk of other childhood cancers like Acute Lymphoblastic Leukaemia. We will also investigate whether dietary factors - including vitamin supplements - in the parents or the child can reduce the risk of a child developing a brain tumour. This study also examines genetic factors which can influence the body's ability to deal with toxins. Some genetic variations, combined with diet and lifestyle factors, may alter the risk of developing some cancers. These interactions need to be examined in greater detail for childhood brain tumours. This national study will examine specific genes and analyse them in conjunction with rigorous assessment of exposures throught to be related to the development of childhood brain tumours. Results obtained from children with brain tumours and their parents will be compared with those from healthy 'control' children and their parents. This is the first study to assess gene-environment interactions in relation to the risk of childhood brain tumours.Read moreRead less
Early Life Stress, Adolescent Brain Development And Risk For Adverse Cognitive And Psychosocial Outcomes

Summary
This project aims to study pre and postnatal childhood factors and examine their association with HPA-functioning, cognition, and mental health during adolescence in the Western Australian Pregnancy Cohort Study (Raine Study). Childhood exposures include not only trajectories of stressful life events, family functioning and mental health status during childhood, but also effects of intrauterine and postnatal growth patterns, and a comprehensive range of psychosocial, familial and environmental f ....This project aims to study pre and postnatal childhood factors and examine their association with HPA-functioning, cognition, and mental health during adolescence in the Western Australian Pregnancy Cohort Study (Raine Study). Childhood exposures include not only trajectories of stressful life events, family functioning and mental health status during childhood, but also effects of intrauterine and postnatal growth patterns, and a comprehensive range of psychosocial, familial and environmental factors. It is our objective to characterise functional polymorphisms for genes related to stress regulation and examine their interactions with early life exposures and their neurobiological consequences. We will also test 16 year old Raine subjects for cognitive ability, and in some we will image their brain activity while performing these tests. We anticipate to enhance the already comprehensive phenotypic Raine Study data base with neurobiological information for future neuroscience studies as the Raine cohort matures. We hypothesise that increased and sustained trajectories of early life stress, family dysfunction or poor mental health during childhood will increase the risk of Raine Study adolescents experiencing: (i) - increased stress sensitivity with higher baseline cortisol levels during adolescence; (ii) - increased adolescent stress sensitivity, if they are carriers of specific haplotypes of the glucocorticoid and mineralocorticoid receptor genes.;(iii) - depression during adolescence, if they are homozygous or heterozygous for the short allele of the serotonin transporter (5-HTT) gene; (iv) - poorer cognitive performance and increased atypical non-prefrontal cortex (PFC) brain activity during cognitive testing as measured by fMRI; and (v) -more mental health problems during adolescence.Read moreRead less
Drivers of ageing and adaptive ageing in middle-aged and older adults. This project aims to answer crucial questions about how our early years influence our health and wellbeing in middle and later life. Drawing on one of Australia’s longest running studies of social and emotional development, we link decades of developmental data collected since 1983 to social, emotional, cognitive and physical wellbeing in participants turning 40 (midlife) and 70 (later life). It will provide insight into impo ....Drivers of ageing and adaptive ageing in middle-aged and older adults. This project aims to answer crucial questions about how our early years influence our health and wellbeing in middle and later life. Drawing on one of Australia’s longest running studies of social and emotional development, we link decades of developmental data collected since 1983 to social, emotional, cognitive and physical wellbeing in participants turning 40 (midlife) and 70 (later life). It will provide insight into important and largely unanswered questions about the way social factors in the first half of life shape our later selves. This study will inform government and health policy targeting ageing populations.

LIFEPATH: Life-course Biological Pathways Underlying Social Differences In Healthy Ageing

Funding Amount
$470,466.00
Summary
Healthy ageing varies across society due to environmental, behavioural and social circumstances that affect peoples’ lives. To improve our ability to change this we will investigate suspected biological mechanisms over the life course. Using repeated blood samples collected during a large prospective study, we will measure a very large number of biological markers and analyse these combined with lifestyle and behavioural information to identify the modifiable predictors of healthy ageing.
A Study Of Mechanisms Of Cognitive Decline In Type 2 Diabetes Mellitus

Summary
Diabetes mellitus and dementia are major public health problems. Diabetes may increase the risk of dementia. This study aims to uncover the mechanism by which diabetes may increase dementia risk. This may lead to finding new ways to prevent or treat diabetes-related dementia and thus reduce the public health burden of dementia.

Summary
Large-scale cohort studies, that follow the health of a large proportion of the general population over time, have enormous potential to inform disease prevention and the optimal use of health services. The planned research will use large scale cohort study data, linked to data on health outcomes and use of health services to provide much needed evidence on Indigenous health, safety of medicines and healthy ageing.

Risk Factors For Long-term Chronic Disease Events In HIV-positive Persons: The D:A:D Cohort Study

Summary
The D:A:D Study is a large, international study assessing risk factors for chronic disease events in HIV-positive patients. We know these events, such as heart attacks and cancers, increase with age. And we also know that these events are more common in HIV-positive people. Over the next five years, D:A:D will assess risk factors for chronic disease events in HIV-positive people as they age, and help optimise patient monitoring and management.

Funding Amount

Summary
Although a late event for most Australians, chronic diseases present a crippling burden for Australia. This project explores their early roots, before overt disease emerges, in 3500 parents and their children in the Longitudinal Study of Australian Children. We will measure how accumulated stress and buffering characteristics play out in the biology of cell ageing and inflammation, in developing heart, lung, kidney and bone health, and in quality of life and health costs to the population.
