Diseases of the 21st century are complex with environmental and genetic causes. At the interface of these is Epigenetics - factors not specified by DNA sequence that control genes. Recent data show much of the risk associated with disease is set early in life, even during the time in the womb. The MCRI CDDE laboratory has assembled teams of researchers of diverse expertise investigating epigenetics of human development and complex disease to hopefully prevent or reverse them early in life.

Improving The Management Of Diabetes In Pregnancy In Remote Australia
Funder
National Health and Medical Research Council
Funding Amount
$2,117,449.00
Summary
This study aims to optimise the management of diabetes in pregnancy (both gestational diabetes and pre-existing type 2 diabetes) and post-partum follow-up of these high risk women in order to reduce the risk of future chronic disease among women and their children. The proposal involves scale-up of successful initiatives that we have developed as part of the NT DIP Partnership, scale-up within the Northern Territory (NT) and to Far North Queensland (FNQ).
Turning Points: Breaking Intergenerational Cycles Of Intimate Partner Abuse And Social Adversity

Summary
Intimate partner abuse (IPA) is estimated to affect one in four women at some stage in their lives, and to impact on the lives of at least one million Australian children annually. This study will investigate the extent to which exposure to intimate partner abuse during pregnancy and in the first 12 months postpartum predicts child outcomes in middle childhood.

Aboriginal Families Study: 5-6 Year Follow-up Of An Intergenerational Birth Cohort
Funder
National Health and Medical Research Council
Funding Amount
$1,676,056.00
Summary
This study will extend follow-up mothers and children in an existing cohort of 344 women who gave birth to an Aboriginal baby in South Australia between July 2011 and June 2013. The study will investigate the health of mothers and children, as the children in the study start school. The study will provide important information about the contribution of early life experiences to health and developmental trajectories of children, and the complex interplay of maternal and child health.
WOmen's Action For Mums And Bubs (WOMB): A Pragmatic Trial Of Participatory Women's Groups To Improve Indigenous Maternal And Child Health
Funder
National Health and Medical Research Council
Funding Amount
$1,766,216.00
Summary
There is strong evidence elsewhere that involving community women in decision-making about strategies to improve the health of mothers and babies is a cheap and effective way of improving health. The WOMB study tests whether community women's groups improve the quality of maternal and child health care and outcomes in Aboriginal and Torres Strait Islander communities, the cost-effectiveness and how it works.
Bridging The Gap: Addressing Refugee Inequalities Through Primary Health Care Service Reform
Funder
National Health and Medical Research Council
Funding Amount
$690,568.00
Summary
This proposal will develop and test interventions to reform maternity and maternal & child health systems to tackle known inequalities in health and health care for vulnerable families, particularly clients of refugee backgrounds. Innovation in system redesign and service delivery will result in sustainable improvements in access to and quality of care and measurable improvements in maternal, newborn and child health.
Impact Of An Infant Sleep Intervention On Infant Sleep And Maternal Wellbeing: A Cluster Controlled Trial

Summary
Infant sleep problems and postnatal depression are common in the Australian community. Over a third of Australians report a problem with their infant's sleep in the second six months of life whilst 10-15% of Australian women will experience an episode of depression in the first year after their child is born. Both infant sleep problems and postnatal depression have been associated with serious outcomes including child abuse, child behaviour problems, maternal physical and emotional problems, fam ....Infant sleep problems and postnatal depression are common in the Australian community. Over a third of Australians report a problem with their infant's sleep in the second six months of life whilst 10-15% of Australian women will experience an episode of depression in the first year after their child is born. Both infant sleep problems and postnatal depression have been associated with serious outcomes including child abuse, child behaviour problems, maternal physical and emotional problems, family stress and family breakdown. This study builds on previous work conducted by researchers at the Centre for Community Child Health, Royal Children's Hospital, Melbourne. In this work, a brief behavioural intervention significantly decreased infant sleep problems and symptoms of maternal depression, particularly for depressed mothers. The intervention consisted of controlled crying and removal of sleep associations such as a dummy which the infant had become dependent upon to fall asleep. Mothers who received the intervention reported 20% fewer sleep problems and a 45% reduction in depression symptoms compared with mothers who did not receive the intervention. The interention also improved maternal sleep quality and quantity and reduced the need for professional sleep services. It was acceptable to mothers, of low cost and was minimally disruptive to families - in contrast to many current strategies directed primarily at postnatal depression. This trial aims to determine whther a similar intervention delivered by Victorian Maternal and Child health nurses within their usual practice settings can replicate these important benefits.Read moreRead less
Early Nutrition, Epigenetics And Developmental Outcomes In Children.
Funder
National Health and Medical Research Council
Funding Amount
$550,093.00
Summary
Increasing evidence demonstrates that early nutrition, including in pregnancy, has long lasting programming effects on later health of children. Evidence implicates epigenetics (literally ‘above DNA’) in mediating these effects. The most convincing data exists for obesity and related disorders such as metabolic syndrome, diabetes, and heart disease. The focus of this project is on understanding how ‘epigenetic’ mechanisms are influencing the way our genes function to cause these disorders.
Endocrine And Molecular Regulation Of Placental CRH Expression

Summary
Approximately 70% of infant death is associated with premature birth. Preterm birth occurs in 6-10% of pregnancies, and there has been no reduction in the rates of premature birth in the last 30 years. This is largely because we remain ignorant of how normal and abnormal birth is controlled. Understanding the physiology of human pregnancy is a critical step in the development of ways to detect and prevent preterm birth.

Preterm birth occurs in 6-10% of pregnancies, and there has been no reduction in the rates of premature birth in the last 30 years. This is largely because we remain ignorant of how normal and abnormal birth is controlled. Understanding the physiology of human pregnancy is a critical step in the development of ways to detect and prevent preterm birth. Our group has demonstrated a link between production of a hormone (corticotrophin releasing hormone, CRH) in the placenta and the length of time the baby is carried in the mother. In women who will deliver prematurely a rise in CRH occurs earlier in the pregnancy and more rapidly, while in women who deliver late the rise occurs more slowly. This work has given rise to the concept of a biological clock that determines the length of time the fetus will be carried by the mother before birth, and in which production of CRH in the placenta plays a central role. We have been studying how the CRH gene is controlled in placental cells. We have discovered some regions in the DNA of the CRH gene which have important roles in controlling how much CRH is made by the placenta. The experiments described in this research project will determine the molecular mechanisms that control the production of CRH in the human placenta. This will be done in two ways: (1) by examining the DNA sequences involved in controlling expression of the CRH gene and (2) by identifying the proteins that actually perform the regulating functions that result in either increased or decreased amounts of CRH being produced by the placenta. This important information will help us better understand how normal and abnormal birth is controlled, and from that knowledge new ways to detect and prevent premature birth can be invented.Read moreRead less
