Summary
Hepatitis C virus (HCV) is usually transmitted by blood-to-blood contact. The risk of transmission by sexual contact has been thought to be low. However, in recent years increasing hepatitis C infection has been documented among HIV-positive gay men, with sexual contact the most most likely means of infection in the majority of cases. This grant will use established cohorts to define levels of hepatitis C risk through sexual contact among homosexual men to inform public health strategies.

Summary
Two hundred million people are infected with the Hepatitis C virus. There is no vaccine and the rate at which new strains of the virus arise enable it to evade the human immune system. This study aims to decipher how new viral strains are generated and transmitted, thereby enabling the development of new vaccines.

Summary
Recent research internationally has revealed that development of the fetus during pregnancy is related to later risk of hypertension and diabetes. Low birth weight infants have higher risk. While research has shown that this can't entirely be explained by genes, it is possible that some genes amplify the effect of low birth weight. This project seeks to identify such genes by examining a set of likely candidates. The targeting of these genes has been based on the knowledge that hypertension and ....Recent research internationally has revealed that development of the fetus during pregnancy is related to later risk of hypertension and diabetes. Low birth weight infants have higher risk. While research has shown that this can't entirely be explained by genes, it is possible that some genes amplify the effect of low birth weight. This project seeks to identify such genes by examining a set of likely candidates. The targeting of these genes has been based on the knowledge that hypertension and diabetes are generally more common in populations that have evolved in the tropics and have more melanin pigment in their skin. The focus in this study, therefore, is on genes that are known to be more common in these populations and also appear to affect risk of blood pressure and diabetes.Read moreRead less
A Five Year Follow-up Of People With Type 2 Diabetes & Other States Of Glucose Intolerance And Associated Risk Factors

Summary
The Australian Prospective Diabetes Study (APDS) is a 5 year follow-up study established to examine the natural history of diabetes and its complications, as well as heart disease and kidney disease. It is a follow-up to the recently completed AusDiab study and addresses some of the important gaps that exist nationally and internationally in the understanding of the burden of Type 2 diabetes and related problems. AusDiab found that 1 in 4 Australians aged 25 years and over has either diabetes or ....The Australian Prospective Diabetes Study (APDS) is a 5 year follow-up study established to examine the natural history of diabetes and its complications, as well as heart disease and kidney disease. It is a follow-up to the recently completed AusDiab study and addresses some of the important gaps that exist nationally and internationally in the understanding of the burden of Type 2 diabetes and related problems. AusDiab found that 1 in 4 Australians aged 25 years and over has either diabetes or a condition of impaired glucose metabolism (this condition is associated with substantially increased immediate risk of heart disease as well as increased risk of diabetes in the future). This new study-APDS, will be the first Australian and indeed international study of its type. We intend to invite 7000 out of the original 11,247 AusDiab sample to participate. Participants who agree to take part in the follow-up study will be involved in 2 ways: 1. A 6-12 monthly contact with participants by telephone or mail to allow reporting of changes in health and utilisation of health services. 2. A 5 year biomedical follow-up survey. This will involve a survey team travelling around Australia to test the participants for diabetes, heart and kidney disease and cardiovascular risk factors (e.g. blood pressure and cholesterol). It will accurately define how many Australians are likely to develop diabetes (as well as kidney and heart disease) in the future, and who is at highest risk. It is expected that outcomes from this study will provide crucial information for both planning and testing public health policy and for the appropriate allocation of resources including specific treatments of individuals and specific groups with or at risk of Type 2 diabetes and its complications within the Australian population.Read moreRead less
Injecting Drug Users: Social Networks And Molecular Epidemiology Of The Hepatitis C Virus

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
Inter-relationships Between Life-stage Transitions, Depression And Cardio-metabolic Health In Young Adults

Summary
This study will investigate how social transitions and depression in young Australian adults affect the development of obesity and the adoption or persistence of behaviours that are associated with the risk of heart disease and diabetes. These behaviours include smoking, poor diet, physical inactivity and alcohol consumption. A better understanding of how psychosocial factors influence risk factors for heart disease and diabetes is needed to improve prevention strategies.
Investigating Low Sun Exposure And Other Possible Early Life Determinants Of Type 1 Diabtes Mellitus

Summary
Type 1 diabetes mellitus is becoming more common among Australian children. The project explores aspects of the modern child's environment that may increase the risk of type 1 diabetes. In particular it aims to assess whether very low sun exposure in early life is adverse. Low sun exposure may be adverse because sun exposure -derived vitamin D is vital for the developing child's immune system. We need to know what level of sunlight and vitamin D children need to prevent disease.
