Summary
It is widely known that alcohol use and alcohol dependence can cause many social problems and morbidity. We know that social and and cultural factors can affect the possibility of becoming alcohol dependent. We also know that inheritance plays a major role in the risk of becoming dependent upon alcohol. Two inherited causes or genes have already been identified as causing some people to avoid alcohol and so have less chance of becoming dependent upon it.

We know that social and and cultural factors can affect the possibility of becoming alcohol dependent. We also know that inheritance plays a major role in the risk of becoming dependent upon alcohol. Two inherited causes or genes have already been identified as causing some people to avoid alcohol and so have less chance of becoming dependent upon it. Clues as to why this happens come from what happens to alcohol following a drink. The body detoxifies itself of alcohol in the liver. There it is converted to very highly toxic acetaldehyde and this is normally rapidly removed by a protein called aldehyde dehydrogenase. Some people do not have a normally functioning form of this protein and cannot remove the acetaldehyde from their bodies. They suffer unpleasant side effects such as nausea, facial flushing and sickness. Consequently they learn by experience to avoid alcohol use and are less likely to develop dependence. We now know that even people with a normally inherited form of aldehyde dehydrogenase can have a lowered risk of dependence. The rate at which our livers convert alcohol to actetaldehyde is also a key factor. Those who are inherently quick at this process again learn to avoid alcohol, others are more at risk. The hypothesis will be tested with a unique set of twins who have provided us with detailed information on how quickly they detoxify alcohol and of their drinking habits for over 20 years. Collectively they will enable us to determine if there is a major genetic influence on alcohol use and dependence that is caused by inter-individual differences in a gene for alcohol metabolism. The DNA of these twins will be used to locate mutations that we predict have a common effect upon our measures of alcohol detoxification, drinking habits and risk of alcoholism.Read moreRead less
Prenatal Alcohol Exposure: A Molecular Mechanism For Memory Deficits Involving The Zinc-binding Protein, Metallothionein

Summary
Damage to the developing brain is the major social and economic consequence of prenatal alcohol exposure but it is unclear the mechanism by which this occurs. This study will assess whether the maternal zinc-binding protein, metallothionein, causes: 1) alcohol-related cognitive deficits, 2) changes in the expression of alcohol-sensitive cognitive genes. We will further assess whether dietary zinc supplementation throughout pregnancy can prevent alcohol-related anomalies in neurodevelopment.
Adolescent Alcohol And Tobacco Use/abuse: The Efficacy Of A Brief Motivational Interviewing And Skills Training Program

Summary
Alcohol abuse (regular and episodic heavy drinking) and tobacco use are common and increasing amongst young Australians. Around 49% of adolescents are regular drinkers, and 15.5% of females and 33% of males are occasional binge drinkers. Between 17.5% and 35.5% of adolescents smoke and this has increased from 1987. While the majority of young Australians moderate their drinking and smoking over time, about 5% will become heavy drinkers and 20% will become regular smokers.

Around 49% of adolescents are regular drinkers, and 15.5% of females and 33% of males are occasional binge drinkers. Between 17.5% and 35.5% of adolescents smoke and this has increased from 1987. While the majority of young Australians moderate their drinking and smoking over time, about 5% will become heavy drinkers and 20% will become regular smokers. The public health consequences of heavy drinking and smoking are now well documented. There are many studies exploring the effectiveness of universal prevention programs designed to reduce the chance of alcohol and tobacco problems in high school students. These are associated with short term reductions in the chance of smoking and heavy drinking, however it is unclear whether these programs work for adolescents who are at high risk of alcohol problems and sustained smoking. We know a lot about the sorts of risk factors associated with these problems. They include early onset of use, parental involvement and use, particular personality traits, poor marks, peer use, and poor social skills. There is no research that clearly evaluates prevention programs for adolescents who show these risk factors. In this research, a program tailored for high-risk adolescents will be compared to an educational program similar to what is often received in Australian high schools. It is expected that high-risk students will not show changes in the educational program, but will show long-term improvements after completing the enhanced program. If these results hold, the research will have very important implications for detecting high-risk students and modifying the ways in which these adolescents are treated so that we minimise the chance of further development of alcohol and tobacco problems. This could result in large health cost savings in the future.Read moreRead less
SOLUTIONS For Present And Future Emerging Pollutants In Land And Water Resources Management

Funding Amount
$259,784.00
Summary
The European Union project SOLUTIONS will develop a novel conceptual framework to prioritise chemical contaminants for ecological and human health risk assessment of water resources and fish for human consumption. The Australian partner will implement health-relevant bioanalytical endpoints to inform cumulative risk assessment. The developed concepts and tools will be validated using European river case studies, with the knowledge generated to be transferred to the Australian context.
Food And Water For Life: Co-creation And Evaluation Of Sustainable Innovations To Strengthen Food And Water Security

Summary
Aboriginal and Torres Strait Islander peoples suffer a disproportionate burden of non-communicable diseases. Poor diets, exacerbated by low quality water supplies, are one of the biggest contributors to this. Through our existing long-standing partnership, his project will establish a framework and use regulatory analysis to support the Aboriginal community in Walgett to develop a transformative community-led food and water security action plan to improve the long-term health and well-being.
