Objective: To examine the prevalence of dementia and problems associated with ageing in the Torres Strait. Methods: The study was conducted across all 18 island and 5 mainland communities in the Torres Strait and Northern Peninsula Area of Far North Queensland.Participants underwent a comprehensive health assessment and a Geriatrician assessment, which were used to establish consensus diagnoses. Results: A total of 276 Torres Strait residents aged between 45 and 93 participated in the study. The prevalence of dementia in the sample was 14.2%, which was 2.87 times higher than the wider Australian population. Conclusion: Torres Strait Islander peoples share the increased risk of dementia seen

Objectives: This study examined relationships between home and community gardening and older adults’ self-reported psychosocial and physical well-being, attitudes to aging relative to gardening activities and benefits of membership to a gardening group. Methods: A survey addressing (a) demographic characteristics, (b) gardening interests and sentiments, (c) activities, (d) benefits, (e) self-rated health and quality of life and (f) attitudes to aging was administered online and via mail-out. Results: Participants, 331 gardeners aged 60–95 years from Australia, reported numerous benefits from leisure gardening. According to multiple regression analysis, Restoration and Physical benefits were the strongest explanatory variables of participants’ positive aging self-perceptions. Members of gardening groups reported significantly more social and physical benefits than non-members. Conclusion: The current study provides support for promoting positive aging through gardening. Regardless of ‘doing’ gardening or simply ‘being’ in the garden, having contact with nature was key to attaining positive therapeutic benefits for this sample.

Highlights Detailed protocol of the Prospective Imaging Study of Ageing (PISA) Study. Genetic risk prediction to identify those at differing risk of Alzheimer’s disease. Longitudinal cohort for the study of precursors and lifestyle risk factors. Use of online surveys and cognitive testing for large scale phenotyping. Functional, structural and molecular neuroimaging with neurocognitive testing.

Objectives. Assessing late-life anxiety using an instrument with sound psychometric properties including cross-cultural invariance is essential for cross-national aging research and clinical assessment. To date, no cross-national research studies have examined the psychometric properties of the frequently used Geriatric Anxiety Inventory (GAI) in depth. ), this study used bifactor modelling to analyze the dimensionality of the GAI. We evaluated the "fitness" of individual items based on the explained common variance for each item across all nations. In addition, a multigroup confirmatory factor analysis (MG-CFA) was applied, testing for measurement invariance across the samples.Results. Across samples, the presence of a strong G factor provides support that a general factor is of primary importance, rather than subfactors. That is, the data support a primarily unidimensional representation of the GAI, still acknowledging the presence of multidimensional factors. A GAI score in one of the countries would be directly comparable to a GAI score in any of the other countries tested, perhaps with the exception of Singapore. Discussion.Although several items demonstrated relatively weak common variance with the general factor, the unidimensional structure remained strong even with these items retained.Thus, it is recommended that the GAI be administered using all items.

Objective: Lifespace, the physical area in which someone conducts life activities, indicates lived community mobility. This study explored the feasibility of technology-based lifespace measurement for older people with dementia and mild cognitive impairment (MCI), including the generation of a range of lifespace metrics, and investigation of relationships with health and mobility status.
