Initiatives -
The general purpose of the ALSA study is to gain further understanding of how social, biomedical and environmental factors are associated with age related changes in health and well-being of persons aged 70 years and over. Emphasis is given in the overall study to defining and exploring the concept of healthy, active ageing, particularly in a South Australian context. The research has a number of specific objectives. These include: - determination of levels of health and functional status of an older population and to track the changes in these characteristics over time - identification of factors which promote and maintain health and well-being in an ageing population - identification of risk factors for major morbid conditions and social, behavioural and other problems among an ageing population - analysis of the effects on transitions in health and functional status of age, gender, different patterns of co-morbidity, availability and nature of informal and formal support arrangements, social and economic circumstances, health care provision and utilisation and other variables of interest - assessment of the effects of disease processes on functional status and the demand for health care services and both informal and formal long term care - examination of the patterns of, the need for, and the utilisation of informal and formal sources of long-term care as they relate to social support networks, economic and housing conditions, care giving arrangements and the availability of appropriate services and - examination of mortality outcomes in the light of changes in health and functional status, medical interventions, self-assessed health, social networks, and individual psychological characteristics **General contact: fcas@flinders.edu.au **

Timeline

Population

The primary sample of the older old adults (70 and older) was randomly drawn from the database of the South Australian Electoral Roll. Persons in the older age groups as well as males were deliberately over sampled to compensate for the higher mortality that could be expected over the study period. In addition, spouses of primary respondents (aged 65 and over) and other household members aged 70 and over were asked to participate.
