Summary
We all began life with a set of genes inherited from our parents. However, it's now known that from the time we were in the womb onwards that genes can be turned off and on by the environment or even completely lost or gained. Even what your mother ate or how she behaved while she was pregnant could have influenced your future health. Because people are so different, we are studying the subtle differences between twins to tease out the factors that may influence our genes and our health.

Summary
The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells ....The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells use epigenetic changes to help control how they grow and develop. Evidence suggests a direct link between diet and environmental influences on our epigenetic profile. Recent research has traced the origins of many of the health problems of adult life back to the earliest periods of development _ to the time spent in the womb and the first few years of life. If we are born with a low birth weight, we are more likely to get sick later in life. Overwhelming evidence exists that the environment in the womb is critical for a healthy birth weight (and health in later life) and it is thought that epigenetics may be the missing link between this environment, low birth weight, and therefore health in later life. In addition, mounting evidence supports a general link between epigenetic de-regulation and predisposition to disease. However, the timing and the overall contribution of environmental- genetic influences to the establishment of faulty epigenetic markings remain largely unknown. Twins are the best model to study this link as they share similar (but not identical environments) and some share identical genetic makeup. Using twins, Dr Jeffrey Craig and his team will investigate the factors in the prenatal environment that modify specific cells, leading to low birth weight and increase disease risk later in life. They predict that this occurs via specific changes in gene activity caused by epigenetic disruption.Read moreRead less
Epigenetic Programming Of Immune Development In Utero: Role Of The Maternal Environment In The Allergy Epidemic

Summary
This study will provide new insights into the development of allergic disease. Specifically, we will explore the hypothesis that allergic disease and other disorders or immune dysregulation occur as a result of gene-environmental interactions in early life, and that these events begin in pregnancy when the developing fetus is still developing and most susceptible to these effects.
Screening and responding to domestic violence experienced by refugee women. We will adapt and test an evidence-based intervention to identify and address domestic violence with newly arrived refugee women, partnering with Settlement Services International, one of Australia’s largest providers of settlement programs. Domestic violence is the lead contributor to premature death among Australian women, and costs $22 b each year, with refugee women at heightened risk.

We will adapt and test an evidence-based intervention to identify and address domestic violence with newly arrived refugee women, partnering with Settlement Services International, one of Australia’s largest providers of settlement programs. Domestic violence is the lead contributor to premature death among Australian women, and costs $22 b each year, with refugee women at heightened risk. This study will compare outcomes for women who receive the intervention to controls and culturally sensitive, scaleable tested tools. This intervention should reduce the human and financial cost of domestic violence among refugee and other vulnerable migrant women, providing tools to settlement services to address this complex, hidden problem.

This project will yield new and important perspectives from citizens on preventive health and health promotion, which can be used to develop better targeted and more effective prevention and promotion policies and strategies. Citizens views will be investigated in relation to vexed issues such as: new approaches to financing and program delivery, reorienting the health insurance sector, reorienting the health system to focus more on prevention and health promotion, improving current approaches of consumer participation in prevention and chronic disease management, tackling broader issues in public policy trade-offs between health and non-health, diversifying workforce roles and involving health professionals in prevention and promotion.Read moreRead less
Intercultural understanding in primary and secondary schools. What facilitates or impedes intercultural understanding in children, adolescents and schools? How can this be addressed? How can we know what makes a difference? This project answers these questions at the individual, school and national level using a novel cultural systems approach and methodological and technological innovations.
The digitisation of school health and physical education. While there is growing enthusiasm for using digital technology in school health and physical education (HPE), this is happening in the absence of systematic empirical research. This project aims to describe the forms digital HPE is taking, analyse the commercial and ideological forces shaping it, and discuss its impacts.

While there is growing enthusiasm for using digital technology in school health and physical education (HPE), this is happening in the absence of systematic empirical research. This project aims to describe the forms digital HPE is taking, analyse the commercial and ideological forces shaping it, and discuss its impacts. It aims to provide educational stakeholders with a knowledge base on which to anchor debate, policy and further research concerning the complex ethical and philosophical issues raised by the digitisation of HPE. As the first HPE research grounded in theories of digital culture, the project also aims to challenge the intellectual foundations of HPE teacher training as well as widely held views about the public health role of schools.Read moreRead less
