OBJECTIVE: To document socioepidemiological theories used to explain the relationship between socioeconomic disadvantage and multimorbidity. DESIGN: Scoping review. METHODS: A search strategy was developed and then applied to multiple electronic databases including Medline, Embase, PsychInfo, Web of Science, Scielo, Applied Social Sciences, ERIC, Humanities Index and Sociological Abstracts. After the selection of studies, data were extracted using a data charting plan. The last search was performed on the 28 September 2021. Extracted data included: study design, country, population subgroups, measures of socioeconomic inequality, assessment of multimorbidity and conclusion on the association between socioeconomic variables and multimorbidity. Included studies were further assessed on their use of theory, type of theories used and context of application. Finally, we conducted a meta-narrative synthesis to summarise the results. RESULTS: A total of 64 studies were included in the review. Of these, 33 papers included theories as explanations for the association between socioeconomic position and multimorbidity. Within this group, 16 explicitly stated those theories and five tested at least one theory. Behavioural theories (health behaviours) were the most frequently used, followed by materialist (access to health resources) and psychosocial (stress pathways) theories. Most studies used theories as post hoc explanations for their findings or for study rationale. Supportive evidence was found for the role of material, behavioural and life course theories in explaining the relationship between social inequalities and multimorbidity. CONCLUSION: Given the widely reported social inequalities in multimorbidity and its increasing public health burden, there is a critical gap in evidence on pathways from socioeconomic disadvantage to multimorbidity. Generating evidence of these pathways will guide the development of intervention and public policies to prevent multimorbidity am

BACKGROUND: Physical inactivity is a modifiable risk factor for dementia, but there remains a research translation gap in effective physical activity (PA) implementation, particularly in the longer-term. The INDIGO trial investigated the effectiveness of a six-month PA intervention for inactive older adults at risk of cognitive decline with subjective cognitive decline or mild cognitive impairment. OBJECTIVE: This follow-up study aimed to collect feedback from INDIGO participants about their experience of involvement in the trial, including barriers and enablers to longer-term maintenance of PA. METHODS: A qualitative study using semi-structured individual interviews was conducted and transcripts analyzed thematically. All INDIGO trial completers were invited, with 29 participating (follow-up period 27-66 months post-baseline). RESULTS: At long-term follow-up, participants described INDIGO trial participation as beneficial. The theme of "Motivation" (subthemes: structure and accountability, knowledge and expected benefits, preferences and motivation, tools) followed by "Situation" (subthemes: environment and time, social aspects, aging and physical health) appeared to be critical to PA "Action". Most participants had a positive view of goal-setting and peer mentoring/support, but there was some polarization of opinion. Key factors to longer-term "Maintenance" of PA were self-efficacy and perceived benefits, habit formation, and for some participants, enjoyment. CONCLUSION: PA interventions for older adults at risk of cognitive decline should include behavior change techniques tailored to the individual. Effective techniques should focus on "Motivation" (particularly structure and accountability) and "Situation" factors relevant to individuals with the aim of developing self-efficacy, habit formation, and enjoyment to increase the likelihood of longer-term PA maintenance.

Despite its well-known health benefits, most older adults do not commit to undertaking sufficient physical activity (PA). In this study we aimed to examine the perceived benefits of and barriers and enablers to PA from the perspectives of older Caucasian and Chinese adults living in Australia. Individual and group interviews with 17 Caucasian (mean age: 72.8 years) and 47 Chinese adults (mean age: 74.0 years) were conducted and analysed using thematic analysis. Overall, participants knew about the benefits of PA on physical health but had inconsistent views on its benefits on mental and cognitive health. Older Caucasian and Chinese adults reported similar barriers (e.g., health issues, costs, bad weather and lack of time) and enablers (e.g., improving health; environmental enablers such as adequate and walkable spaces and good natural environment; peer support; and self-motivation) to PA. In comparison, older Chinese adults reported barriers more often, and reported some unique barriers relating to language and culture issues. The findings contribute to developing targeted PA programs for older Caucasian and Chinese adults.

Objectives: Physical activity (PA) is beneficial for older adults' cognition. There is limited research investigating perspectives of support persons (SPs) of next-of-kins (NOKs) with cognitive impairment. This exploratory study aimed to investigate perspectives of SPs of older adults with Alzheimer's Dementia (AD) or Mild Cognitive Impairment (MCI). Methods: A telephone survey of 213 SPs of NOKs from the Australian Imaging, Biomarkers and Lifestyle Flagship Study of Ageing (AIBL) was undertaken to quantitatively assess SPs' beliefs and knowledge about PA benefits, current PA level of their NOK, and PA program preferences. The contribution of age, gender, diagnosis and mental health symptoms was assessed using multiple logistic regression analyses. Results: Many SPs were aware of PA benefits for memory (64%) and believed it would help their NOK (72%). Older SP age was associated with less awareness of benefits (p = 0.016). SPs caring for male NOKs were more likely to believe that PA would be helpful than those caring for female NOKs (p = 0.049). NOK AD diagnosis (rather than MCI) (p = 0.014), older age (p = 0.005) and female gender (p = 0.043) were associated with lower PA levels. SPs were mixed regarding preference for their NOKs to participate in individual (45%) or group (54%) PA. Many SPs wanted to participate in PA with their NOK (63%). Conclusions: The results highlight that SPs have high levels of awareness of the cognitive benefits of PA, and describe their preferences regarding PA programs. The findings provide new information to inform targeted public health messaging, PA prescribers and providers, and future research directions.

BACKGROUND: This protocol describes an ongoing study of the impact of befriending on depression, anxiety and loneliness in older people living in residential aged care facilities in Australia. While systematic reviews of befriending have indicated positive benefits of befriending for people in a range of ages and settings, there have been no randomised controlled trials (RCTs) of befriending for older people living in residential aged care with depression and no studies of the cost effectiveness of befriending in residential aged care facilities (RACFs) in Australia. METHODS AND ANALYSIS: We are conducting a single blind pragmatic RCT comparing two groups of older people living in RACFs, one receiving an intervention consisting of weekly befriending for 4 months from a trained volunteer and the other receiving treatment as usual. Participants undergo eligibility screening for depression (GDS-15 ≥ 4) and cognitive impairment (GPCog ≥ 4) and assessments at three measurement time points: baseline prior to randomisation, 2 months post-baseline and 4 months post-baseline. The primary outcome measure is depression, and secondary outcome measures are anxiety, loneliness, social isolation and quality of life. The economic evaluation will take the form of a cost-utility analysis based on the outcome of quality of life. The primary and secondary outcomes will be analysed using negative binomial and logistic regressions utilizing the Generalised Estimating Equations approach. DISCUSSION: To our knowledge, this is the first RCT evaluating the effectiveness of befriending on older people with depression living in residential aged care. It is expected that the befriending intervention will reduce the severity of depression symptoms experienced by older people living in residential aged care. If the intervention proves effective it may be incorporated into volunteer training programs and adopted as a way of supporting older people's mental health. TRIAL REGISTRATION: Trial registe

Objectives: This review informed development of the first national Physical Activity (PA) Guidelines for Older Australians with Mild Cognitive Impairment (MCI) or Subjective Cognitive Decline (SCD) (http://www.dementiaresearch.org.au/images/dcrc/output-files/1567-pa_guidelines_for_mci_or_scd_full_report_final.pdf). These guidelines are directed at healthcare professionals and aim to encourage older adults with SCD/MCI to engage in PA to enhance cognitive, mental and physical health. Design: A narrative review was undertaken to inform the guideline adaptation process. Methods: A systematic search of existing PA guidelines for older adults was performed and evaluated using the Appraisal of Guidelines for Research and Evaluation II Instrument. The guideline assessed as most appropriate was adapted to the population with SCD/MCI using the Guideline Adaptation Resource Toolkit, supported by the narrative review. Results: The search for existing PA guidelines for older adults yielded 22 guidelines, none of which specifically considered older adults with SCD/MCI. The Canadian Physical Activity Guidelines for Older Adults were selected for adaptation to the population with SCD/MCI. The narrative review found 24 high-quality randomised controlled trials and 17 observational studies. These supported the four guideline recommendations that address aerobic PA, progressive resistance training, balance exercises and consultation with healthcare professionals to tailor PA to the individual. Conclusions: This review found evidence to support the four guideline recommendations. These recommendations provide specific guidance for older adults with SCD/MCI, their families, health professionals, community organisations and government to obtain benefits from undertaking PA. The review also highlights important future research directions, including the need for targeted translation and implementation research for diverse consumers.

AIMS AND OBJECTIVES: To understand the attitudes and perceptions of older people with limited English proficiency (LEP) and healthcare workers to using mobile translation technology for overcoming language barriers in the healthcare setting. BACKGROUND: Australia's cohort of people aged 65 and over has a sizeable population with LEP. In healthcare settings, difficulties with communication may potentially result in inadequate care. Mobile language translation applications have been identified as a potential way to improve communication between patients and healthcare staff when used as an adjunct to professional interpreters in low-risk scenarios; however, the perceptions of the use of mobile translation applications for such communication is unknown. METHODS: A multi-method design was used. Focus group discussions were conducted with older people from culturally and linguistically diverse (CALD) backgrounds and nursing and allied health professionals to understand their perceptions of translation technology. Qualitative data were analysed using inductive content analysis. Qualitative findings were reported using the Standards for Reporting of Qualitative Research (SRQR) checklist. Participants also appraised three existing translation apps via survey and results were analysed using descriptive statistics. RESULTS: Overall, older people from CALD backgrounds (n = 12) and healthcare staff (n = 17) agreed that translation technology could play a role in reducing communication barriers. There was enthusiasm amongst older people to learn and use the technology, while healthcare staff saw the potential to address communication barriers in their own work. Barriers identified by older people and healthcare staff included: accuracy of translation and phrases, possible technological learning curves, risk of mistranslation in high-risk conversation and inability to check accuracy of translation. Fixed-phrase translation apps were seen as more favourable than real-time voice-to
