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
Fine Mapping Of The ADH Region For Alcohol Metabolism, Use And Dependence

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

It also aims to identify factors that predict the onset of depression in those who do not receive the intervention. The intervention focuses on the training of interpersonal problem solving skills and enhancement of optimistic thinking styles within a classroom-based curriculum. This project extends the current research program of the applicant. The intervention has already been developed and implemented with 1600 young people, with the support of local education authorities. The evaluation uses well-researched measures and includes a control group of adolescents who do not receive the intervention. Around 5% of adolescents experience clinical levels of depression and an even larger percentage show subclinical levels. Depression results in many debilitating consequences such as impaired school, work and social functioning and is also a risk factor in adolescent suicide. The prevention of mental health problems is a priority for Commonwealth and State governments and yet there is minimal research to demonstrate the effectiveness of preventive interventions, particularly in the area of depression. If the present study demonstrates a positive outcome, it will provide important guidelines as to preventive materials that should be included in the school curriculum. It is predicted that: a) the intervention will be associated with lower levels of depression over the 4 year follow-up, particularly for adolescents who are assessed as showing mild symptoms of depression, poor problem solving skills or pessimistic cognitive style prior to intervention b) risk factors for the development of depression in adolescents who do not receive the intervention will include initial mild symptoms of depression, poor problem solving skills and pessimistic attributional style.Read moreRead less
Identifying Endophenotypes For Eating Disorders And Their Relationship To Specific Genotypes And Environments

Summary
Around 15% of Australian women will have an eating disorder at some time in their life, and half of these will experience significant levels of depression and suicidality. The current project seeks to build better models of the initiation and maintenance of eating disorders that can inform development of effective treatments, with identification of genes and environments that predict the various components that define eating disorders (i.e., behaviours, temperaments and cognitive flexibility).
