Australian Ageing Research Agenda
Priorities and Challenges
David Le Couteur
Professor of Geriatric Medicine
Centre for Education and Research on Ageing
University of Sydney

Demographers note a demographic revolution, wherein
the proportions of the young and the old will undergo a
historic crossover...This portrait of change in the world's
population parallels the magnitude of the industrial
revolution - traditionally considered the most significant
social and economic breakthrough in the history of
humankind since the Neolithic period.
Old age is the main risk
factor for disease and
disability after 28 yrs
(Harman 2001)

Evidence for healthcare
– little evidence for efficacy
• >4% of RCT are older people
– efficacy often absent
– adverse outcomes greater
Future $$ predictions
• Baby boomers graduate to retirement in 2011
• Intergenerational Report, costs associated with
ageing will amount to $84 billion within 40 years
• Health care - $15.5 billion
• Pharmaceuticals - $46.5 billion
• Aged care and pensions - $22 billion
Evidence for health policy (AHR, Lowe & Kasap, 2002)
“New ways of doing things in health care are usually
introduced with little or no scientific evaluation …
Political and economic imperatives, often seeming to be
based on little other than the whim of State or
Commonwealth ministers results in management
directives to rationalize reformulate and change tried
and tested systems...”
Where is ageing research in Australia?
• NATIONAL RESEARCH PRIORITY AREAS
• 17 areas covering defence, environment, technology and health
• “Ageing well, ageing productively”
NHMRC Scoping Study(CERA, NARI consortium)
• designated ageing/geriatric research poorly funded
• minor NHMRC representation
• productive in terms of publications
• performed by “non-ageing” researchers

Survey of Australian ageing researchers
• N=79
• average age 45
• 42% research degree
• 49% hospitals, 25% university, 20% institute
• 61% medical, 25% science, 14% other
The conclusions of the report
• Ageing research
– primary focus on ageing
– multidisciplinary
– interface with health
care
• Infrastructure needs
– career development
– ageing animals
– longitudinal studies
Ageing research will succeed if
• targeted funding and seeding
– area of extraordinary need vs current orphan
status
• primary focus on ageing
– not disease, gene or methodology
• multidisciplinary
– ageing is complex therefore solutions will be
multifaceted
