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
Do Exposures Before Conception Influence The Risk Of Asthma In Offspring?

Summary
Asthma and poor lung function are major causes of public health issues. Emerging evidence suggests adverse exposures even before the conception of a child may cause these conditions. The proposed project is part of an international study across generations to identify these factors. This study will provide novel evidence to guide interventions and identify studies to advance this area further. These original findings will be of great importance both nationally and internationally.
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
Environmental Risk Factors And Genetic Modifiers For Lung Health And Lung Function In A High Risk Cohort

Funding Amount
$95,348.00
Summary
Asthma is an important determinant of respiratory health and longevity. While early life exposures are thought to be important, the evidence linking them with asthma and lung function is inconclusive. There is a scarcity of longitudinal studies and few investigate genes and environment. This study will determine whether environmental exposures along with their relevant genetic modifiers are related to increased risk of asthma and impaired lung function in a high allergy risk birth cohort.
The Predictors Of Asthma And Lung Function Deficits In The Third Decade: Longitudinal Study Of MACS Sibships

Funding Amount
$1,176,908.00
Summary
This will be the world’s first birth cohort study to use substantial prospective data to investigate how biological, psychosocial, and environmental markers from birth will predict asthma and lung function in the third decade of life. Our findings will be crucial to the development of new policy and practice for the prevention and management of these conditions and uncover crucial risk factors for young adult asthma.
Defining An Ethical And Evidence-based Approach To Clinical Research In Children And Adolescents With Chronic Kidney Disease (CKD)

Funding Amount
$84,800.00
Summary
Chronic kidney disease (CKD) in children and adolescents is a serious health condition, which impacts patients' academic abilities and achievement as well as their social wellbeing and their physical and mental health. This study will investigate the range of impacts that CKD has on patients and families, and explore the ways that these problems should best be addressed in future research from the perspective of patients and their families.
The Second Australian Study Of Health And Relationships

Summary
The present proposal is for the Second Australian Study of Health and Relationships, a survey of 20,000 Australians aged 16–69, in 2011–12 in order to understand and document the changes in Australian sexual behaviour over the past decade. It is essential that policy and practice in the arena of sexual and reproductive health be evidence-based and that the evidence base be as current as is practicable.
