Australians are living longer and expected to work for longer than ever before. It is critical that additional years of life are at least matched by the increase in the years lived in good health, and that gains in healthy ageing are experienced across all sectors of society. There is also a great need to balance older adults’ capacity and opportunity to work with societal pressures to delay retirement.
The objective of this three-year project is to better understand individual and societal determinants that underlie variation in healthy ageing. We will identify characteristics that are tied to the years that older adults are able to engage in productive activities and live independently in good health. To achieve this, advanced health expectancy estimation methods are being used to analyse newly available mortality records that have been linked to national longitudinal survey data. These analyses will produce new, refined, estimates for Australia of ‘healthy life expectancy’ with ‘working life expectancy’. We will examine how these differ across sociodemographic strata, change over time, and compare internationally.
The project is funded by an Australian Research Council (ARC) Discovery Project (DP190100459).

With increasing age, nearly all adults experience progressive, irreversible, and bilateral declines in hearing ability. As a result, hearing loss is one of the most common chronic health conditions affecting older adults and if unmanaged its impacts are wide ranging and long lasting.
There is good evidence indicating that older adults with significant hearing difficulties are more likely to experience cognitive decline and dementia, but reasons for this association are unknown.
This project will investigate how hearing loss is related to cognitive impairment. Firstly, it will compare levels of hearing function and use of hearing services by cognitive status. Second, it will examine if the relationship between poor hearing and impaired cognitive functioning is explained by lower levels of participation in activities that are good for brain health. Third, it will investigate if hearing rehabilitation services and hearing aids protect against poorer levels of cognitive function.
The project is funded by a Dementia Australia Research Foundation (DARF) Project Grant
This is a trial designed to test a new intervention to support people with early stage dementia and their care partners. The research will combine three existing interventions based on self-management, health promotion and e-learning into one extended educational program. We hope to improve well-being and support people to live in their own homes for as long as possible by providing the relevant knowledge, information and skills directly to the people with dementia.
The Personality and Total Health (PATH) Through Life Project has been led by Professor Anstey since 2006 and has been based at ANU since 1999. It is a large on-going population-based longitudinal cohort study comprising approximately 7500 participants. The study includes three cohorts including a younger (aged 20–24 at baseline), midlife (aged 40–44 at baseline) and older (aged 60–64 at baseline) adults randomly sampled from the electoral roll of the ACT and the nearby city of Queanbeyan. Additional waves of data collection have occurred in 4-year increments, with wave 5 of data collection being completed for the younger cohort and soon to commence for the midlife cohort. The study involves many national and international collaborations.
The broad aims of the PATH study relate to clinical outcomes that constitute the major burden of disease within the Australian community.
Primary PATH Objectives:
Several design features of the PATH project contribute to its unique standing among population-based longitudinal cohort studies.
This project has been funded primarily by the National Health and Medical Research Council. Wave 5 40s and 60s follow-ups are funded by the ARC Centre of Research Excellence in Population Ageing.

The General Practice Knowledge Translation (GP-KT) project is an online survey designed to help us understand what people already know about dementia risk and dementia risk reduction in frontline healthcare settings.
In particular we are keen to understand the barriers that might delay or prevent dementia risk reduction activities so that we can work to reduce these over time.
At the moment we are recruiting Australian General practitioners and their teams. International versions are the survey are also in development.
Older adults represent a growing sector of the driving population in Australia, and while driving can be important for maintaining social engagement in late life, age-related changes such as cognitive and visual impairment can impact on driving safety.
The Driving, Ageing, Safety and Health (DASH) project is designed to develop and validate screening measures for older drivers to support determinations of driving safety. The DASH project is a collaboration with Joanne Wood and the Queensland University of Technology.
Over 550 older drivers, across three groups, were followed for two years to evaluate how well laboratory assessments and an on-road test predict driving outcomes. The three groups included a) older drivers referred for assessment by GPs and Road Safety Authorities, b) older drivers with eye disease and c) older drivers drawn from the community.
Findings from this research project will enable health professionals and licensing authorities to assist in their decision-making regarding the fitness to drive of older adults.
DASH is funded by the National Health and Medical Research Council.
Current road safety policy for at-risk older drivers involves ‘fitness to drive’ assessment and either license restriction or revocation. However, research indicates that there is no clear evidence that mandatory testing lowers crash rates amongst older drivers, and that driving cessation in older adults is associated with increased rates of depression, social isolation, and general health decline.
The Better Drive program includes a series of studies evaluating interventions to improve driver skill. Two trials have been completed to date.
Trial 1 used a two-arm randomised controlled trial (RCT) approach to investigate the efficacy of individually tailored driving refresher lessons against a group-based refresher course on on-road driving performance, safety and crash risk in older adults. Findings indicate that although classroom based road rules workshops for seniors can lead to improvements in on-road driving skill, the inclusion of tailored driving instruction can significantly enhance safety and reduce crash-causing on-road errors relative to classroom based workshops alone.
Trial 2 used a two group (training, no-contact control) non-randomised design to examine the transfer of computerised speed of processing (SOP) training gains to cognitive measures that are known predictors of driving safety in older adults. Findings indicate that SOP training effects can be achieved with self-administered, online training at home, with some transfer to other known cognitive predictors of driving safety. However, differential effects of training may be observed for tasks requiring goal-directed search strategies rather than diffuse attention.
A third trial is currently underway. This trial uses a three-arm randomised controlled trial approach to assess the effectiveness of computerised cognitive training and tailored on-road skills training on driver safety in older adults. Data collection for this trial will be completed in 2019.
The Better Drive program has been funded by the NRMA Road Safety Trust.
A growing number of modifiable risk and preventative factors for dementia have been identified. Primary care offers a natural setting for the identification of those who may be at particular risk and who may subsequently benefit most from risk reduction interventions.
The Body, Brain, Life – General Practice (BBL-GP) project – a continuation of the original Body Brain Life study – evaluates the efficacy of lifestyle management programs for reducing risk profiles for dementia in adults recruited from primary care. The project compares three different interventions: a BBL-GP intervention designed to reduce the risk of cognitive decline, a Lifestyle Modification Program (LMP) designed to enhance general wellbeing and improve lifestyle to reduce risk of chronic disease, and an Active Control condition. A total of 120 adults participated in the trial.
The BBL-GP intervention group completed eight online e-learning modules designed to improve dementia literacy, knowledge of risk factors, physical activity, nutrition, health, cognitive activity, social activity and mood. This group also received tailored face-to-face physical activity and nutrition sessions. Participants in the LMP group participated in group sessions on basic nutrition, meal planning, physical activity, health conditions, motivation and goals, medications and sleep. The Active Control group received weekly emails with links to information regarding lifestyle risk factors and disease management.
Outcomes were assessed immediately following the intervention, 18-weeks post-intervention, and 36-weeks post-intervention. The final follow-up at 62-weeks post-intervention is due to be completed in mid-2018. A cost evaluation of the two interventions will also be completed.

The NHMRC Dementia Centre for Research Collaboration (DCRC) was established in 2006 under the Australian Government’s Dementia Initiative. DCRC projects are diverse and map onto the priorities of the NHMRC National Network for Dementia Research (NNIDR). A key focus is applied research on topics meaningful to people with dementia and their family carers.
There are three DCRC hubs located at UNSW, NeuRA and QUT, respectively. The three-hub framework aims to grow partnerships and strengthen ties with consumers and service providers, Dementia Training Australia and Dementia Support Australia in order to progress prevention, assessment, care and translation of knowledge into everyday practice, as well as building the next generation of dementia researchers.
The primary focus of the DCRC NeuRA hub is risk reduction and prevention including individual, community and population-based interventions targeting lifestyle risk factors for dementia.
The flagship project of the DCRC NeuRA hub is the International Research Network on Dementia Prevention (IRNDP). Founded in 2017, the IRNDP is a multinational network bringing together researchers who are working to reduce the risk of dementia across the world. For more information on the network, visit the IRNDP website, including news and updates, an evidence hub on cohort studies, an evidence synthesis on clinical trials, and information on how to join.
The DCRC is funded by the National Health and Medical Research Council.
The Centre of Research Excellence in Cognitive Health focuses on the integrally linked areas of optimising cognitive health and the prevention of cognitive decline.

Globally, dementia cases are increasing at a rate of 21 per cent annually, and most of these are occurring in low to middle-income countries. With no cure for neurodegeneration or the diseases that cause dementia, there is an urgent need to link both knowledge translation and researchers more closely together in a global effort to tackle prevention more effectively.
Founded in 2017, the International Research Network on Dementia Prevention (IRNDP) is a multinational network bringing together researchers who are working to reduce the risk of dementia across the world.
IRNDP aims to:
The goals of the IRNDP have particular relevance in low- to middle-income (LMIC) countries as exposure to lifestyle and clinical risk factors becomes more common as LMIC economies grow.
While there are many current overlapping public health, patient, research, policy and practice initiatives aimed at prevention or treatment of dementia, IRNDP is the first single collaborative network of researchers to focus attention on prevention that is truly global.
IRNDP is chaired by Professor Kaarin Anstey and is a project of the Dementia Centre for Research Collaboration funded by the NHMRC National Institute for Dementia Research (NNIDR).
The Dementia Risk Factors and Assessment (DemRisk) program involves over ten years of research performed by the Anstey group on the identification and assessment of risk factors for Dementia.

In addition to being highly prevalent, hearing and vision impairment affect older adults for substantial periods of their remaining life. Given their broad ranging impacts on health and well-being, sensory impairments are ideal targets for strategies to compress morbidity in late life.
Our largely theory-based findings suggest a strong case for greater investment in risk factor reduction programmes that target modifiable lifestyle factors, particularly increased engagement in physical activity. However, further data on risk factor treatment and dementia risk reduction from population-based studies are needed to investigate whether our estimates of potential dementia prevention are indeed realistic.
