Summary
Over the last 25 years, the prevalence of overweight and obesity increased over 9 times among Chinese children and adolescents. The aims of this project are to assess the trends of blood pressure levels in children during the period of obesity epidemic, and to estimate the effects of obesity and other factors on the trends of blood pressure levels. In this repeated cross-sectional study, we will analyse the data of six surveys collected over a period of 25 years with over 1.4 million participant ....Over the last 25 years, the prevalence of overweight and obesity increased over 9 times among Chinese children and adolescents.

Family Study Of Ear Health And Metabolic Diseases In A Western Australian Aboriginal Community

Summary
A family-based study of diseases in a Western Australian Aboriginal community is planned. Patterns in DNA within families will be related to patterns of disease in two areas of health that are of major concern to this Aboriginal community, ear health in children (e.g. runny ears; perforated eardrums) and type 2 diabetes. Finding genetic determinants of disease provides information that can complement clinical, epidemiological and public health understanding of disease.
The Role Of Sarcopenia And Undernutrition In Disability After Hip Fracture

Summary
Hip fracture is one of the most costly and devastating medical events which can befall an elderly individual, and is expected to affect 40,000 Australians per year by the year 2040. It often results in permanent loss of walking abilities and independence, as well as a severely diminished quality of life. For example, 80% of elderly Australians who fracture their hip will not regain their previous level of walking ability, 20% will have died, and up to 25% will be in permanent nursing home reside ....Hip fracture is one of the most costly and devastating medical events which can befall an elderly individual, and is expected to affect 40,000 Australians per year by the year 2040. It often results in permanent loss of walking abilities and independence, as well as a severely diminished quality of life. For example, 80% of elderly Australians who fracture their hip will not regain their previous level of walking ability, 20% will have died, and up to 25% will be in permanent nursing home residence 12 months later. Although hip fracture has been thought of as a problem primarily related to osteoporosis (age-related loss of bone), it is now increasingly clear that other factors such as muscle wasting and weakness, gait and balance problems and poor dietary intake are also risk factors for this condition. Although surgical techniques have advanced to the point that most operations to repair hip fracture are now successful, the rehabilitation outcomes are disappointingly poor compared to other orthopaedic injuries. We believe that this is because recovery after hip fracture is in fact not primarily related to the bone disease itself, but to inadequate muscle bulk and strength. It is likely that already frail patients with a new hip fracture will experience further muscle wasting over time, because of their very low levels of physical activity, poor nutritional intake, depression, social isolation, and impaired memory in some cases. Their poor diet may be related in part to their difficulty in getting out of the home, preparing meals, reduced appetite and poor morale in the post-fracture period. If our theory is correct, then we will be able to prove that disability after hip fracture is closely related to muscle mass, and many common clinical problems contribute to this underlying mechanism of dysfunction. We will test these ideas by following patients who have had a hip fracture for 12 months with periodic detailed assessmentsRead moreRead less
Dietary Protein Effects In Elderly Women: Musculoskeletal, Renal, Cardiovascular And Body Composition Endpoints

Summary
Fractures and falls of the elderly are major health problems in our community in terms of disability and cost. It is critical to the future health of our aging population to develop non-pharmaceutical interventions to maintain health into old age. Epidemiologic studies have shown that relatively high protein intake is associated with increased bone mineral mass and reduced incidence of osteoporotic fracture in elderly people. Low protein intakes can lead to loss of muscle mass. To date there hav ....Fractures and falls of the elderly are major health problems in our community in terms of disability and cost. It is critical to the future health of our aging population to develop non-pharmaceutical interventions to maintain health into old age. Epidemiologic studies have shown that relatively high protein intake is associated with increased bone mineral mass and reduced incidence of osteoporotic fracture in elderly people. Low protein intakes can lead to loss of muscle mass. To date there have been no randomised trials of sufficient duration to examine the effects of increased dietary protein intake on bone and muscle health of the elderly. The aim of this study is to examine the effectiveness of protein supplementation for the prevention of osteoporosis and muscle wasting in elderly women, and the safety of such an intervention through monitoring renal function and risk factors for cardiovascular disease. Two hundred and twenty women will be recruited to this study and be assigned to protein group or placebo group. Women in the protein group will received 250 ml high protein drink (containing 30 g protein) per day and women in the placebo group will receive placebo drink containing the same amount of energy, calcium but no additional protein. Bone structure, muscle mass, body composition, renal function and risk factors for cardiovascular disease will be monitored during the 2 year study period. The results of this randomised, controlled study will clarify the role of protein on bone mass and structure, muscle mass and body composition in the elderly. At the same time, the safety of such intervention on renal and cardiovascular endpoints will also be evaluated. It is envisaged that the results of this study if positive will translate into both immediately applicable intervention strategies that are relevant at a program and an individual level.Read moreRead less
