Summary
This study will follow-up injecting drug users that participated in research in the 1990s and 2000s to examine mortality rates in these groups over time. Identifying information from these studies will be cross-referenced with National Death Index data to determine participants that died and the dates of their death. This study will be the first in Australia to determine mortality rates over time in a defined cohort of injecting drug users outside drug treatment settings.

Identifying information from these studies will be cross-referenced with National Death Index data to determine participants that died and the dates of their death. This study will be the first in Australia to determine mortality rates over time in a defined cohort of injecting drug users outside drug treatment settings. Studying a defined group overcomes some of the problems associated with mortality rate estimates based simply on the number of injecting drug-related deaths. Although the number of deaths can be found, the number of people at risk of injecting drug-related death is unclear because of the hidden nature of drug use and the dynamic characteristics of drug use and drug markets. The examination of mortality trends among injecting drug users over time can provide insights regarding changes in drug use patterns and markets. For example, this study will examine changes in injecting drug use mortality across periods of high heroin availability in the late '90s and periods of interrupted heroin supply - the heroin 'drought' - from 2000 onwards. In addition, factors related to injecting drug-related mortality can be explored by comparing the characteristics of injecting drug users that died and those that survived, such as drug use and drug treatment histories, co-morbidities such as mental illness and socio-demographic backgrounds. This information can inform overdose prevention and harm reduction strategies by identifying individuals most at risk of injecting drug-related mortality. This study will also draw attention to the significant public health burden of injecting drug use. In addition, by comparing the results from this study with other similar studies from overseas, we can more reliably compare mortality among groups of Australian injecting drug users with their peers in other countries.Read moreRead less
Understanding Gene-environment Interactions In Relation To Risk Of Age-related Cataract

Summary
Age-related cataract is the clouding of the lens, a leading cause of visual impairment among older persons. The burden of this common eye disease will only increase as the population ages. Besides age, other environmental and genetic risk factors that increase the risk of cataract have been identified. The aim of this research is to examine how the interplay of genes and environment contributes to age-related cataract formation, using population-based data of established studies.
Genetic And Environmental Risk Factors On Lifetime Risk Of Obstructive Lung Disease

Summary
Classification of lifetime phenotypes of obstructive lung disease allows investigation of the effect of environmental and genetic influences on specific phenotypes along with the interactions between them. Through improved phenotyping ,the currently inconsistent relationships between asthma and COPD and their associations with genetic and environmental factors may become clearer.
Investigating The Relationships Between Cannabis And Other Drug Use, Mental Health, Early-life Factors And Life-course Outcomes: Integrative Analyses Of Data From Four Australasian Cohort Studies

Funding Amount
$292,097.00
Summary
The current study will be the first of its kind to use integrative data analyses _ a highly innovative approach _ to pool data from four large and long-running Australasian cohort studies to better understand the link between cannabis use and later-life outcomes. Dramatically improved knowledge of these relationships will create a clearer picture of the interventions required to reduce the harms associated with cannabis use.
Do Breast Cancer Risk Factors Differ According To Underlying Genetic Susceptibility? A Pooled Analysis Of Prospective Studies From The NCI Cancer Cohort Consortium
Funder

Funding Amount
$418,581.00
Summary
We propose to use data from 23 international prospective cohort studies in the Cancer Cohort Consortium organised by the US National Cancer Institute to evaluate gene environment interactions for women who are at increased genetic risk of breast cancer. Our ultimate goal is to enhance the performance of clinical prediction tools and to develop targeted evidence-based strategies to mitigate the high absolute risk of breast cancer for women at increased genetic risk of the disease.
