Attrition in longitudinal studies: advancing and evaluating statistical methods. Longitudinal studies are a vital tool for monitoring the health and well-being of Australians. They are uniquely placed to examine changes in diseases over time and prospectively collect data on exposure and disease onset. There have been many successful longitudinal studies in Australia that have lead to significant breakthroughs in evidence-based health (e.g. the Nambour Skin Cancer Prevention Trial). Unfortunatel ....Attrition in longitudinal studies: advancing and evaluating statistical methods. Longitudinal studies are a vital tool for monitoring the health and well-being of Australians. They are uniquely placed to examine changes in diseases over time and prospectively collect data on exposure and disease onset. There have been many successful longitudinal studies in Australia that have lead to significant breakthroughs in evidence-based health (e.g. the Nambour Skin Cancer Prevention Trial). Unfortunately all longitudinal studies suffer from attrition, or loss of participants, which leads to questions concerning their validity and generalisability. This project will investigate the causes of attrition, and the effect attrition has on longitudinal studies, in order to improve their design and analysis.Read moreRead less
I am investigating several areas relating to Paediatric surgery in particular the quality and coverage of paediatric surgical trials. The context for this study is to evaluate the current state of paediatric surgical research for methodological rigour, aiming to establish an evidence base and agenda for future trials to improve outcomes in paediatric surgery. The project will involve epidemiological methodology studies and systematic reviews, data linkage and analysis of existing study datasets.
Modelling The Possible Effects Of Low-dose Irradiation In Young Australians Exposed To CT Scans

Funding Amount
$130,877.00
Summary
Radiation from CT (computerised tomographic X-ray) scans of children may cause a later increase in cancer risk. However, any risk for an individual will be small, so we are using de-identified records to study the average risk of cancer in 600,000 young Australians exposed to CT scans between 1985-2005. Our project has the capacity to detect an increase of 10% in the risk of exposed compared with non-exposed. Results will be available by Dec 2012.
Eliminating HCV: Statistical Modelling And Health Economic Evaluation In The New DAA Era

Funding Amount
$318,768.00
Summary
While new generation hepatitis C virus (HCV) treatments are highly efficacious, their high cost means multi-pronged approaches will be needed to reach elimination targets. This project will use statistical and mathematical modelling to inform real world health economic evaluations determine the most cost-effective response. This will inform health policy in Australia and globally.
We will conduct a study of more than 500 Australian female twin pairs in which one or both have had breast cancer. We will also study measured and unmeasured genetic and environmental causes of risk factors.
The Impact Of Infections, Anaemia, And Micronutrient Deficiencies On Infant Birth Weight And Growth
Funder
National Health and Medical Research Council
Funding Amount
$83,613.00
Summary
This research aims to determine the impact of infectious diseases, anemia and nutritional deficiencies on low birth weight and infant growth in rural Papua New Guinea. The health of pregnant women and their babies will be assessed during pregnancy and up to 12 months post birth. We will determine which health indicators cause low birth weight and poor infant growth to enable development of interventions to improve health and pregnancy outcomes.
Statistical Analysis Of An International 10 Year Prospective Family Study Of Gene-environment Interactions On Risk Of Female Breast Cancer.
Funder

Funding Amount
$450,198.00
Summary
This study will provide new and credible information on how the effects of environmental and lifestyle factors on breast cancer risk depend on a woman's underlying genetic susceptibility using a large, international 10 year prospective family study.

Globally tuberculosis infects over 9 million people yearly. In low incidence countries TB is re-emerging, with HIV, drug resistance and migration driving this. Australia needs to examine the transmission of TB within our country and The Asia-Pacific region. This proposal will quantify the risk for importation of highly drug resistant TB into Australia and assess the factors that lead to outbreaks. Models will be informative for Australian TB policy development and contribute to regional and glob ....Globally tuberculosis infects over 9 million people yearly.

Min/Max Autocorrelation Factors in Time Series Studies of the Adverse Health Effects of Ozone. The annual health costs associated with exposure to air pollution in Australia have been estimated at between $3 and 5.3 billion. Given these costs, it is vital to conduct research that ensures public health officials and policy makers stay fully informed of Australia’s air pollution problem.

The annual health costs associated with exposure to air pollution in Australia have been estimated at between $3 and 5.3 billion. Given these costs, it is vital to conduct research that ensures public health officials and policy makers stay fully informed of Australia’s air pollution problem. The project proposes to address this need by developing methodology to detect trends in air pollution concentrations and reduce measurement error in recorded air pollution concentrations. This will enable relevant authorities to produce more accurate estimates of air pollution health costs and implement more appropriate pollution regulations and health warnings.Read moreRead less
Understanding spatial trends in HIV/AIDS infections in South Africa and Australia. This project will develop quantitative methods that will be used to inform public health officials in understanding past and current HIV/AIDS epidemics as well as planning for the future of these epidemics.

This project will develop quantitative methods that will be used to inform public health officials in understanding past and current HIV/AIDS epidemics as well as planning for the future of these epidemics. It will understand not only the behavioural and demographic characteristics of importance as risk factors for HIV infection in South Africa, the epicentre of the global HIV pandemic, but also the geographical spatial locations in which HIV cases are likely to emerge in the future. This project will also forecast the future geographical trends in Australia's changing HIV epidemic in order to plan for intervention strategies and prepare clinical practice appropriately.Read moreRead less
