Summary
Despite dental fear being one of the most common fears experienced by Australians, the etiology of this serious condition is still not well understood and both the prevention and treatment of dental fear are not widely or effectively implemented. This project aims to better understand the psychological processes at work in determining dental fear through further research as well as by gaining first hand experience at one of only a handful of dental fear research clinics in the world.

Summary
This study will explore what happens in the community when a medicine is withdrawn from the market or discredited due to safety concerns. It will examine the impacts of two recent cases of medicine withdrawal or serious long-term safety concern, on a large cohort of women with high utilisation rates who were monitored during the time the medicines were discredited. The study will be an important guide to future regulatory, media and provider responses when medicines are discredited.

Summary
Much earlier work in adults has pointed to the teens as a common point at which many of the important causes of chronic disease and disability in adults begin. These include problems such as tobacco use, depression and anxiety disorders, obesity, alcohol abuse and illicit drug use. However, only a prospective study is able to clarify to what extent common health risk behaviours of teenagers pose a threat to later health and well-being and what characteristics indicate those most likely to go on ....Much earlier work in adults has pointed to the teens as a common point at which many of the important causes of chronic disease and disability in adults begin. These include problems such as tobacco use, depression and anxiety disorders, obesity, alcohol abuse and illicit drug use. However, only a prospective study is able to clarify to what extent common health risk behaviours of teenagers pose a threat to later health and well-being and what characteristics indicate those most likely to go on to problems such as nicotine dependence, recurrent depression and illicit drug abuse. The proposal deals with the follow-up ten years on of a representative sample of 2000 Victorian teenagers. Seven earlier waves of data collections have ascertained levels and risk factors for common behavioural and mental health problems in the teens and early twenties. These problems included depression and anxiety, smoking, heavy alcohol consumption, illicit drug use, deliberate self-harm, obesity, eating disorder, sexually risky behaviour, intravenous drug use, antisocial behaviours and accidental injury. This follow-up of participants at the age of 24 to 25 years will ascertain persisting rates of these problems including levels of substance dependence and mental disorder. Social outcomes such as educational achievement, employment, relationships, parenthood and friendships will be ascertained. In addition mouth washes will be used to collect DNA to allow investigation of genes that may make a contribution to more severe mental disorder and substance dependency. This study will give a clear picture of the outcome and consquences of common adolescent health problems. It will also clarify further psychosocial factors that contribute to their onset or outcome. Together with an analysis of candidate genes the study should make a great contribution to the information necessary for planning effective preventive intervention.Read moreRead less

Summary
Mental health and alcohol disorders are major public health problems which cause long-term disabilities, poor health and early mortality. Addressing these problems requires a better understanding of the early factors leading to these disorders. This research program represents a unique opportunity to increase our knowledge of the origins of these disorders and significantly contribute to improved mental health and alcohol prevention policies and programs.
The Natural History Of Injecting Drug Use Among IDU In Melbourne: A Prospective Cohort Study

Funding Amount
$760,869.00
Summary
Our response to the emergent epidemic of methamphetamine injection is hampered by our lack of understanding of injecting drug use (IDU) natural history that place users at risk of harm and the effectiveness of interventions. This study will examine typical trajectories of IDU and provide a framework for service evaluation. The study will focus on untreated methamphetamine and heroin users, providing the first clear indication of the comparative harms associated with these different types of IDU.

Summary
The hepatitis C virus (HCV) continues to spread among injecting drug users (IDUs) in Australia at a very high rate, despite success in preventing the spread of HIV in the same groups; the complete reasons for this remain unclear. There is an urgent need for the HCV epidemic among IDUs to be contained. To do so, we must better understand the ways in which it is spreading among IDUs.

There is an urgent need for the HCV epidemic among IDUs to be contained. To do so, we must better understand the ways in which it is spreading among IDUs. Much is known about risk behaviours of individual IDUs and how they contribute to HCV transmission; much less is known about how these behaviours are modified by the influence of the IDUs peer group, especially their immediate and intimate social networks. Despite its importance in influencing attitudes and behaviours, and therefore HCV transmission, this has never been studied in Australia, nor, in relation to HCV, in the world. We hope that by studying social and risk networks of IDUs we shall discover new ways in which control of the HCV epidemic can be achieved in Australia. We intend to do this among two groups of young IDUs, one of Vietnamese ethnicity, located in the one suburb of Melbourne. By using field techniques for gathering information (ethnography), and sophisticated analytic techniques to understand how these networks are formed and influence behaviours, we hope to be able to identify interventions which work at the level of the social group rather than the individual in bringing about the behaviour change necessary to prevent HCV transmission. To ensure that the risk networks we describe are as influential as they appear, and to discover more about the variability of HCV, we will also be investigating the relationship between the various strains of HCV in members of the IDU networks, particularly as another measure of the connectedness of networks and network members. This will be done using sophisticated genetic analysis of the HCV obtained from network members by blood test.Read moreRead less
Australian Vietnam Veterans Health Study: Cohort Wave 2

Summary
Military records show that Australia has committed troops to war since the time of the Boer War, continuing commitments through World Wars I and II, the Korean War, the Malaya Emergency, the Vietnam Conflict, the Gulf War, and numerous peacekeeping operations across the world, yet there has never been an epidemiological cohort study that tracked the path of their health and their lives after their return.

This study will provide an approximate 10-year followup of an established cohort of Australian Vietnam veterans, which was the first such study ever conducted of returned Australian servicemen. It will test diagnostic stability and chart the trajectory of health and welfare over time in the men and relate this to possible causal determinants including military service, combat deployment and trauma exposure, post traumatic stress disorder and alcohol disorders. It will also allow us to examine the role of their previous health state, determined 10 years ago, in relation to their current health state. Data and methodology from the Australian Bureau of Statistics national surveys on physical and mental health will be incorporated so that comparisons can be made with Australian population data for the study group. Significantly, wave 1 preceded automatic compensation for veterans for cancer and PTSD; provoked the DVA's national survey that led to a $32M government program response; fed into the DVA mental health policy; fed into the Army selection guidelines for overseas service via the Psychology Corps; fed into DVA policy re Vietnam Veterans Counselling Service. Wave 2 will continue this informative process as the cohort ages. This study will provide a firmer basis for treatment of war veterans and others whose lives are visited by trauma, physical ill-health, alcohol disorders, or mental health problems in adulthood.Read moreRead less
