The Australian Longitudinal Study of Ageing
The Australian Longitudinal Study of Ageing (ALSA) is the centrepiece research activity of the Flinders Centre for Ageing Studies. The ALSA commenced in 1992 with 2087 participants aged 65 years or more. At Baseline, a comprehensive personal interview and assessment of neuropsychological and physiological functions was undertaken at each person's home, supplemented by self-completed questionnaires, biochemistry, and additional clinical studies of physical function. The final wave (Wave 13) of data collection was carried out in 2014.
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
The breadth and scope of ALSA are unusual, even by comparison with longitudinal studies of ageing conducted in other countries. For instance, at Baseline, ALSA included both spouses of 565 married couples, who have been followed over the course of the study. The inclusion of both survey and clinical components makes it possible to link objective clinical measures with details of the lifestyle, attitudes and personal histories of respondents. With the added dimension of repeated observations over time, ALSA provides a richness of data not available in previous Australian studies, and promises to substantially increase our understanding of the quality of life of older South Australians.
Recent funding from the Australian Research Council's Discovery Projects Scheme has enabled a multidisciplinary team of researchers to study Adelaideans with an average age of 91 years. The project, Resilient ageing and the oldest-old in the Australian Longitudinal Study of Ageing, gathered data on the fastest growing sector of the Australian population. This data will be combined with ALSA data collected previously to enable the dynamics of ageing to be revealed, i.e. it will look prospectively at risk and protective factors associated with ageing well.
A qualitative study was also carried out during 2014 where a sub sample (20) of ALSA participants undertook in-depth interviews of life story narratives to explore how life course experiences may contribute to successful ageing. The ALSA data provide a rich source for secondary analysis.
The material collected during the ALSA comprises the most comprehensive longitudinal
data base yet assembled on ageing Australians and it complements in a unique way
those available internationally. The findings of the ALSA are directly relevant to policy
formulation and planning of health and social services for an ageing population.
Researchers have reported on the Australian Longitudinal Study of Ageing in over 200
publications including reports, book chapters, refereed journal articles, abstracts,
conference proceedings and theses. (See ALSA Bibliography.)
