Summary
Studies of the causes and consequences of health outcomes follow large cohorts of individuals for long time periods. A major challenge in analysing data from these studies is that information is often incomplete. Participants rarely complete all waves of data collection, or provide all requested information. Statistical research has led to increased use of a statistical method (multiple imputation) that recovers information from incomplete cases. This project will develop and improve this method
Measuring Changes In Fluids, Fat, Muscle Mass, Proteins & Other Body Components Non-invasively Through Course Of Illness

Summary
The course of non-cancer related disease is difficult to assess clinically making it hard for clinicians to accurately predict the end of life course of illness for patients. No matter what the end of life disease is, death will involve multi-system organ failure and changes in body composition. These changes, including fluid distribution, muscle mass and type and fat mass as well as measures of body mass index, basal metabolic rate and arm muscle circumference can be accurately followed with no ....The course of non-cancer related disease is difficult to assess clinically making it hard for clinicians to accurately predict the end of life course of illness for patients. No matter what the end of life disease is, death will involve multi-system organ failure and changes in body composition. These changes, including fluid distribution, muscle mass and type and fat mass as well as measures of body mass index, basal metabolic rate and arm muscle circumference can be accurately followed with non-invasive multi-frequency bio-impedance. This information will provide a basis to either confirm the clinical diagnosis or lead to recommendations for change.Read moreRead less
A Life Course Approach To Understanding Oral Health Inequalities

Summary
Preadolescent children in Australia have lower rates of dental decay than children in almost all other economically developed countries. This is not the case for Australian adults. In fact, Australian adults aged 35-44 years have higher rates of dental decay than adults of similar age in most other economically developed countries. Not only do Australian adults have comparatively poor oral health in the lead-up to midlife, but also socioeconomic inequalities in dental decay are more pronounced a ....Preadolescent children in Australia have lower rates of dental decay than children in almost all other economically developed countries. This is not the case for Australian adults. In fact, Australian adults aged 35-44 years have higher rates of dental decay than adults of similar age in most other economically developed countries. Not only do Australian adults have comparatively poor oral health in the lead-up to midlife, but also socioeconomic inequalities in dental decay are more pronounced at this stage of life than at any other stage before or after. This study proposes to look at how oral health in young adults in shaped by their experiences across childhood, adolescence and early adulthood. This approach is based on recent evidence that points to the importance to adult health of the early years of life. In this life course perspective, the poorer health of disadvantaged individuals is seen to result from ongoing and cumulative exposure to difficult and disadvantaged circumstances across their life course. This study will trace and follow up a cohort of almost 10, 000 South Australians for whom social, familial, economic and dental behavioural information was collected in 1991-92 when these individuals were aged from five to 15 years. Now aged from 19 to 29 years, these individuals will be invited to attend a dental examination and complete a survey that will provide information on health behaviours and life circumstances shown to be important determinants of general and oral health status. One purpose will be to explore reasons for the comparatively poorer oral health status of Australian adults. A second purpose will be to investigate the magnitude of socioeconomic inequalities in oral disease at different life stages. The findings will add to the knowledge of the etiology of oral disease and open up opportunities to develop new methods of oral health promotion based on the understanding of accumulated risk across the life course.Read moreRead less
Early School-Age Outcomes After Exposure To Repeat Prenatal Corticosteroids - A Randomised Controlled Trial

Summary
AIMS OF THE RESEARCH We have recently concluded a large clinical trial in Australia and New Zealand of repeat dose of antenatal corticosteroids given to women who were likely to deliver their baby too early (before 34 weeks of pregnancy). We have been able to show that repeat doses of corticosteroids before birth significantly reduces the risk of the baby developing respiratory difficulties after birth from 41.4% to 32.8%. However, we are not sure if this potentially important improvement will t ....AIMS OF THE RESEARCH We have recently concluded a large clinical trial in Australia and New Zealand of repeat dose of antenatal corticosteroids given to women who were likely to deliver their baby too early (before 34 weeks of pregnancy). We have been able to show that repeat doses of corticosteroids before birth significantly reduces the risk of the baby developing respiratory difficulties after birth from 41.4% to 32.8%. However, we are not sure if this potentially important improvement will translate into better outcomes for the children as they grow older and reach school-age. As there are many examples of treatments given around the time of birth that have been shown to have some short-term benefits, but substantial long-term harms, we must be as certain as we can be that any advance in one small area of health is not counterbalanced by disadvantages in other health areas. This is particularly important to find out for repeat antenatal corticosteroids given the earlier conflicting reports from non-randomised studies. We plan to assess the 1085 survivors from our earlier clinical trial of repeat dose of prenatal corticosteroids when they are of early school age. We will assess their movement and other important areas of their brain function, as well as their school progress, blood pressure, lung function and general health and growth. EXPECTED OUTCOMES OF THE RESEARCH If we find important improvements in health outcomes at school-age in children exposed to repeat corticosteroids, without any substantial couterbalancing adverse effects, repeat steroids will be recommended standard therapy in women who are likely to give birth to their baby very early. This will lead to a reduction in the burden of ill health.Read moreRead less
