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.

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
The Risk Factors For Ecstasy And Related Drug Overdose: A Case-crossover Study

Summary
Our ability to respond to the emergent harms of Ecstasy and Related Drug (ERD) use is hampered by our lack of understanding of the practices users engage in that place them at risk of harm. This study will examine the risk factors for non-fatal ERD Emergency Department (ED) admission in a sample of non-fatal ERD overdose victims recruited through two hospital EDs in Melbourne.

This study will examine the risk factors for non-fatal ERD Emergency Department (ED) admission in a sample of non-fatal ERD overdose victims recruited through two hospital EDs in Melbourne. The research involves a case-crossover study of the risk factors for ERD-related ED admission, as well as a detailed case series of ERD-related ED admissions. The case-crossover investigation will involve a comparison between behaviours occurring prior to the critical drug use episode with typical drug use behaviours and more specifically those occurring prior to a control use episode (another occasion on which ERDs were used). Data will be collected by Researchers positioned in the ED, with information collected on the specifics of the critical and control use episodes through interviews with participants following stabilisation and a return to consciousness. The case series will be established from all ERD-related ED admissions flagged as such by triage nurses. Potential risk factors under study will include the environmental conditions in which the drug was used (eg time of day, physical location), other drug taking behaviour, personal factors (eg asthma, depression) and other dose-related issues (eg amount purchased, source of purchase). Statistical analysis will establish the major differences between the critical, typical and control use episodes. The proposed research will examine risk factors for ERD-related harms within the context of an understanding of the usual practices and behaviour of users of these drugs. Identifying transient change in risk behaviours will provide a foundation for developing contextually-sensitive strategies for harm minimisation. The development of a detailed case series will impact upon the treatment and management of acute ERD-related harms.Read moreRead less

Summary
New knowledge required to address infectious diseases and mental illness among two disadvantaged and overlapping groups -people who inject drugs (PWID) and prisoners – will be produced: Cross sectional and longitudinal studies will examine HIV risk in specific populations; A system to track the emergence of injecting will be developed; The global scale of mental illness and TB among PWID will be determined; and how to improve coverage and delivery of TB prevention and treatment will be explored.
Opioid Dependent Persons In Pharmacotherapy: Blood Borne Viruses And Cancer Risk

Summary
Opioid dependent persons in pharmacotherapy in NSW are at increased risk of death from cancer. We will examine the occurrence of infection with hepatitis and HIV among this high-risk population using data linkage. We will define the relationship between infection, the duration, frequency and type of pharmacotherapy, and cancer risk. The findings will guide effective strategies that will reduce cancer incidence and mortality among this group, and minimise the associated health care costs.
Occupational Exposure To Lead Compounds And Human Cancer

Summary
This study aims to investigate whether there is a link between cancer (in particular cancer of the stomach, lung, kidney and central nervous system) and occupational exposure to lead compounds. There are only a few published cohort studies available on occupational exposures in use and applications of lead compounds, despite the widespread use of these compounds in the past 50 years.

There are only a few published cohort studies available on occupational exposures in use and applications of lead compounds, despite the widespread use of these compounds in the past 50 years. Since the late 1980s the use of lead compounds in Australia has decreased, but Australian and world lead production has increased. Australia is the world's biggest producer of lead. The precise number of lead workers worldwide is unknown but there are likely to be more than 2 million workers of which many are in developing countries where control of lead exposure is unsatisfactory and occupational exposure limits are considerably higher than in developed countries. Evidence for or against cancer risk with exposure to lead compounds , in particular inorganic lead, will therefore have implications for many Australian and international workers. This is also important for health risk assessment for environmental contamination in the Australian community. In our study we will review the state government archived records of about 8,000 lead workers in New South Wales, Victoria and South Australia, who took part in lead compound exposure surveys and had blood tests in the 1970s, 1980s and 1990s, as part of government lead regulations in force at the time. We will then match the details of these workers against the National Cancer and Death registry data to calculate cancer rates. This should involve a sufficient number of workers to enable us to undertake a comprehensive health evaluation of cancer risk and exposure to lead compounds.Read moreRead less
Our aim is to develop appropriate infrastructures necessary to facilitate access by researchers to the accumulated data, including questionnaires, direct physical measurements, blood, DNA and other tissues collected on over 40,000 people in the Health 2020 Cohort Study (Health 2020) and, subject to proposals being judged sufficiently meritorious by an approved peer review process and gaining HREC approval, to facilitate supervised access to participants as required.

This project adopts novel statistical modelling and machine learning approaches to understand the development of lifestyle behaviours in early childhood. Despite the pivotal role of lifestyle behaviours in influencing health and quality of life, little research exists on lifestyle behaviours in early childhood. This project will establish a comprehensive understanding of lifestyle behaviours in early childhood by identifying key developmental time points, mechanisms of behavioural change, and children at risk of developing poor lifestyle behaviours. The project will inform strategies and policies to optimise lifestyle behaviours from the start of life and showcase the capabilities of novel methods in advancing behavioural epidemiology.Read moreRead less
