RESUMO
BACKGROUND: Rates of dementia for Aboriginal and Torres Strait Islander peoples are three to five times greater compared to non-Indigenous Australians, with earlier age of onset. However, the risk and protective factors that drive these higher rates vary across existing cohort studies, with minimal findings on the role of vascular risk factors beyond stroke. Harmonisation of data across studies may offer greater insights through enhanced diversity and strengthened statistical capabilities. This study aims to combine three landmark cohort studies of Aboriginal and Torres Strait Islander participants to better understand the determinants of cognitive health and dementia. METHODS/DESIGN: Three cohort studies - the Kimberley Healthy Adults Project (KHAP, N = 363), Koori Growing Old Well Study (KGOWS, N = 336) and Torres Strait Dementia Prevalence Study (TSDPS, N = 274) - share a similar research methodology with demographic, medical history, psychosocial factors, cognitive tests and consensus clinical diagnoses of cognitive impairment and dementia. Associations between risk and protective factors of interest and the presence of dementia and/or cognitive impairment diagnoses will be evaluated by univariable and multivariable logistic regression in a harmonised cross-sectional cohort of 898 participants. Factors associated with incident dementia and/or cognitive impairment will be assessed in a subset of KHAP (n = 189) and KGOWS participants (n = 165) who were available in longitudinal follow-up, after exclusion of those with baseline dementia or cognitive impairment. Analyses in relation to outcome measure of death or dementia will be conducted to account for the competing risk of death. Logistic regression will be used to evaluate the association between the individual components of the 16-component Kimberley Indigenous Cognitive Assessment (KICA) tool and the presence of dementia and cognitive impairment determined by independent consensus diagnoses. Multivariable binary logistic regression will be used to adjust for the effect of confounding variables. Results will be reported as odds ratios (OR) with 95% confidence intervals (95% CI). DISCUSSION: Greater understanding of risk and protective factors of dementia and cognitive impairment relevant to Aboriginal and Torres Strait Islander peoples may improve approaches across the life course to delay cognitive decline and reduce dementia risk.

OBJECTIVES: To determine the prevalence and demographic, social and health characteristics associated with co-occurring psychological distress symptoms, risky alcohol and/or substance use among a national sample of Aboriginal and Torres Strait Islander people aged 15 years or older. METHODS: This study uses secondary cross-sectional data from the 2018-19 National Aboriginal and Torres Strait Islander Health Survey (NATSIHS). Data were collected via face-to-face interviews with those living in private dwellings across Australia. Participants were Aboriginal and Torres Strait Islander people (n = 10,579) aged 15 years or older. Data pertaining to psychological distress, alcohol and substance use were obtained and weighted to represent the total population of Aboriginal and Torres Strait Islander people in Australia. RESULTS: A total of 20.3% participants were found to have co-occurring psychological distress, risky alcohol use and/or substance use, and 4.0% reported co-occurrence of all three conditions. Female participants in a registered marriage and fully engaged in study or employment had lower rates of co-occurring conditions. Poorer self-rated health, one or more chronic conditions and increased experiences of unfair treatment and physical harm in the past 12 months were associated with increased rates of co-occurring conditions. CONCLUSION: A range of potential risk and protective factors were identified for co-occurring psychological distress, risky alcohol and/or substance use among Aboriginal and Torres Strait Islander people. This information is critical for planning effective holistic strategies to decrease the burden of suffering imposed upon the individual, family and community members impacted by co-occurring conditions.

RESUMEN Este estudio etnográfico fue diseñado para explorar las condiciones de vida de un grupo de familias aborígenes residentes en un contexto urbano, beneficiarias de un programa sociorecreativo en Sídney, Australia. El objetivo fue explorar la satisfacción vital mediante el análisis de sus condiciones de vida y del capital cultural inscrito en sus actitudes, percepciones y conocimientos establecidos. El trabajo de campo se estructuró en dos fases complementarias: en la fase 1, entre mayo de 2008 y diciembre de 2010, se inició con el ingreso del primer autor como voluntario en la asociación responsable del programa y, en la fase 2, entre enero de 2011 y febrero de 2013 se intensificó el proceso de observación participante y las entrevistas semiestructuradas. Los resultados muestran que el proceso de desarraigo cultural está en la base de las experiencias vitales de desigualdad social experimentadas y apunta a un efecto de cohorte que llega hasta nuestros días. Dicho proceso de (des)consonancia cultural debe ser tenido en cuenta como un factor clave a la hora de analizar las condiciones de vida y bienestar de estas minorías étnicas, así como a la hora de desarrollar programas e intervenciones.
ABSTRACT This ethnographic study was designed to explore living conditions among a group of aboriginal families residing in an urban context, who participated in a recreational social program. The aim of the study was to explore life satisfaction by analyzing their living conditions and cultural capital inscribed in established attitudes, perceptions, and lay knowledge. Fieldwork was carried out in two complementary phases: phase 1, between May 2008 and December 2010, began when the first listed author initiated volunteer work with the organization responsible for the program; in phase 2, which extended from January 2011 to February 2013, participant observation was intensified and semi-structured interviews were carried out. The results indicate that the process of cultural uprooting underscores the experience of social inequality, and suggest a cohort effect that continues to this day. This process of cultural (in)consonance must be taken into account as a key factor when analyzing the living conditions and well-being of ethnic minorities, as well as when developing programs and interventions.
