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.

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

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.

Summary
Why many people with diabetes mellitus are afflicted by gastrointestinal (GI) symptoms remains uncertain. Irreversible damage to the nerves controlling the gut (autonomic neuropathy) is often considered to be important. An alternative cause of increased GI symptomatology in diabetics is poor glucose control. Some studies have shown that acute shifts in glucose levels induce changes in the gut relevant to the onset of GI symptoms.

Irreversible damage to the nerves controlling the gut (autonomic neuropathy) is often considered to be important. An alternative cause of increased GI symptomatology in diabetics is poor glucose control. Some studies have shown that acute shifts in glucose levels induce changes in the gut relevant to the onset of GI symptoms. For example, high glucose levels acutely cause slower stomach emptying times, leading to feelings of fullness. Though the effects of chronic glucose levels are yet to be properly explored, population data show that poor control in the long-term is related to an increase in symptoms. The aim of this prospective study is to determine the roles played by both autonomic neuropathy and glucose control in the development of GI symptoms among diabetics. All past research has been cross-sectional, and so cannot tell us if one or both of these factors cause GI problems in diabetes. For example, it is possible that autonomic neuropathy causes an increase in GI symptoms such as nausea and fullness, which in turn induces poor glucose control though lack of appetite or inadequate stomach emptying. Upon study inclusion, all study participants will undergo a series of autonomic tests. At 3 month intervals for a period of 30 months, they will be asked to complete a 2-week diary card detailing their GI symptoms and glucose readings, and also supply blood and urine samples for analysis twice each year. Two years from the study outset, participants will again complete the autonomic test series. Psychiatric co-morbidity will be investigated using the Composite Diagnostic Interview (CIDI-Auto) at the autonomic testing time points. The study will be undertaken at the Gastroenterology Research Unit at Nepean Hospital, in collaboration with the Royal Adelaide Hospital, centres with proven track records in diabetes investigation.Read moreRead less

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.

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

Out of the 2,862 Indigenous participants, 2,503 (87.5%) agreed to have another Check in a few years time. A follow-up study is proposed for the consenting WPHC participants (any any other adults who wish to participate). This study will have 5 main objectives: 1. Estimate the incidence rate of chronic disease conditions (diabetes, renal disease, CVD) and the main determinants of these in the north Queensland cohort (It is expected that Torres Strait Islanders will have different patterns to Aborigines), 2. Estimate the change over a 5 year period in risk factors and complications (including hospitalisations) of those with existing chronic conditions 3. At a community level, evaluate the effectiveness of local interventions aimed at health improvement (e.g. one community has drastically changed rules about alcohol availability, other communities have significantly improved the supply of fresh fruit and vegetables, still others have commenced family savings programs which improve the availability of money over the week and enable savings to buy fridges etc). 4. Estimate whether the early detection of chlamydia and gonorrhoea (using routine urine PCR testing) has lowered the community prevalence of bacterial STIs, and 5. Evaluate the effectiveness of local health promotion programs (e.g. tobacco control initiatives, healthy weight programs). The study will be undertaken in collaboration with Apunipima Cape York Health Council, the Torres Strait Health Council and relevant local community organisations. It will involve skills development for local Indigenous researchers and practitioners. Results will be given back to communities and individuals, with opportunities for further planning.Read moreRead less

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.
