BACKGROUND: Addressing Indigenous food security and food sovereignty calls for community-driven strategies to improve access to and availability of traditional and local food. Participatory approaches that integrate Indigenous leadership have supported successful program implementation. Learning Circles: Local Healthy Food to School is a participatory program that convenes a range of stakeholders including food producers, educators and Knowledge Keepers to plan, implement and monitor local food system action. Pilot work (2014-2015) in Haida Gwaii, British Columbia (BC), showed promising results of the Learning Circles (LC) approach in enhancing local and traditional food access, knowledge and skills among youth and adolescents. The objective of the current evaluation was therefore to examine the process of scaling-up the LC vertically within the Haida Nation; and horizontally across three diverse First Nations contexts: Gitxsan Nation, Hazelton /Upper Skeena, BC; Ministikwan Lake Cree Nation, Saskatchewan; and Black River First Nation, Manitoba between 2016 and 2019.
METHODS: An implementation science framework, Foster-Fishman and Watson\'s (2012) ABLe Change Framework, was used to understand the LC as a participatory approach to facilitate community capacity building to strengthen local food systems. Interviews (n = 52), meeting summaries (n = 44) and tracking sheets (n = 39) were thematically analyzed.
RESULTS: The LC facilitated a collaborative process to: (1) build on strengths and explore ways to increase readiness and capacity to reclaim traditional and local food systems; (2) strengthen connections to land, traditional knowledge and ways of life; (3) foster community-level action and multi-sector partnerships; (4) drive actions towards decolonization through revitalization of traditional foods; (5) improve availability of and appreciation for local healthy and traditional foods in school communities; and (6) promote holistic wellness through steps towards food sovereignty and food security. Scale-up within Haida Gwaii supported a growing, robust local and traditional food system and enhanced Haida leadership. The approach worked well in other First Nations contexts, though baseline capacity and the presence of champions were enabling factors.
CONCLUSIONS: Findings highlight LC as a participatory approach to build capacity and support iterative planning-to-action in community food systems. Identified strengths and challenges support opportunities to expand, adopt and modify the LC approach in other Indigenous communities with diverse food systems.

The development and dissemination of health messaging is a critical component of reducing health disparities. Participants (n = 87) from a human biomonitoring study in six Dene communities responded to a survey about health communication regarding contaminants. The survey included questions on awareness of health messages and risk perceptions related to country foods and contaminants. The vast majority of participants reported eating country foods (99%) and heard that country foods had beneficial nutrients (90%). Seventy per cent of respondents had heard or seen messages about fish with high levels of mercury, and 60% had concerns about the safety or quality of country foods they consumed. Respondents who reported decreasing the number of fish they ate since hearing the messages about fish and mercury had lower (p = 0.04) mercury concentration in hair, compared to those who had not heard the messages. However, no differences in hair mercury were observed for respondents who reported to have changed their fishing location, chosen smaller fish or eaten less predatory fish since hearing the messages. Results indicate the need to examine reasons for self-reported behaviour changes, in addition to awareness. The conclusions of this study can inform the development of messaging and risk management decisions about contaminants within Indigenous populations.

In Canada, most people prefer to die at home. However, the proportion of deaths that occur in hospital has increased over time. This study examined mortality rates and proportionate mortality in Innu communities in Labrador, and compared patterns to other communities in Labrador and Newfoundland. We conducted a cross-sectional ecological study with mortality data from the vital statistics system. This included information about all deaths in Newfoundland and Labrador from 1993 to 2018. We used descriptive statistics and rates to examine patterns by age, sex, cause and location. During the 2003 to 2018 period the leading cause of death in the Innu communities (excluding external causes) was cancer, followed by circulatory disease and respiratory disease. Between 1993 and 2018, there was a lower percentage of hospital deaths and a higher percentage of at home deaths in Innu communities than in the rest of the province. The majority of deaths among Innu were due to cancer and chronic diseases. We found a higher percentage of at home deaths in Innu communities compared to the rest of the province.

UNASSIGNED: Dementia disproportionately affects First Nations populations. Biomarkers collected in primary care may assist with determining dementia risk. Our previous underpowered study showed some suggestive associations between baseline biomarkers with follow-up dementia or cognitive impairment. The current study extended this work with a larger linked dataset.
UNASSIGNED: Probabilistic data linkage was used to combine four baseline datasets with one follow-up assessment of dementia status 0-20 years later in a First Nations population in Australia. Mixed Effects Generalized Linear Regression models were used to test associations between baseline measures and follow-up status, accounting for repeated measures within individuals.
UNASSIGNED: Linked data were available for 88 individuals, with 101-279 baseline observations, depending on the type of measure. Higher urinary albumin to creatine ratio was associated with greater risk of cognitive impairment/dementia, whereas body weight and key lipid markers were negatively associated. There was no clear trend when these associations were examined by timing of measurement (i.e., ≤10 years or >10 years before a dementia assessment).
UNASSIGNED: The results of this study support findings from our previous work and indicate that microalbuminuria can be an early indicator of dementia risk in this population. The weight and lipid profile findings reflect the mixed results in the published literature and require further investigation and interpretation.

BACKGROUND: This paper describes how First Nations Kidney Warriors (Aboriginal and Torres Strait Islander people living with kidney disease), dental hygienists, kidney health care professionals, an Aboriginal hostel accommodation manager and researchers co-designed an approach to improve oral health in South Australia. Kidney Warriors have strong connection to Country, Community and family that underpins health, wellbeing and approaches to research. However, significant colonisation, racism and marginalisation have impacted Kidney Warriors\' social, cultural and financial determinants of health, leading to increased chronic conditions including kidney disease. Access to culturally safe, affordable and responsive oral health care is vital but challenging for First Nations Peoples undergoing dialysis and kidney transplantation; Australian oral health care is generally provided privately, in metropolitan centres, by professionals who may hold unconscious bias about First Nations Peoples and incorrect assumptions regarding equal access to care.
METHODS: The AKction - Aboriginal Kidney Care Together Improving Outcomes Now kidney care oral health working group codesigned strategies to address disparities and gaps in care, and co-create more accessible, responsive, culturally safe and sustainable models of care. A decolonising and collaborative participatory action research was informed by Dadirri Deep Listening and Ganma Knowledge Sharing with repeated cycles of Look and Listen, Think and Discuss, Take Action Together. A small pilot evaluation survey of clinical placement in an Aboriginal setting was undertaken.
RESULTS: Four phases of collaboration were undertaken. Community and health professional consultations identified key gaps and priorities. Clinical yarning and cultural safety training and an interprofessional skills day was co-facilitated. Dental hygienist student clinical placement at Kanggawodli Aboriginal Hostel was initiated and evaluated. First Nations Kidney Warriors were positioned as educators and experts of their own lives and health care needs. A new framework for kidney health-oral health cultural safety and clinical education was developed.
CONCLUSIONS: This codesigned approach involving inter-professional collaboration and joint decision making with community members has significantly informed improvements in oral health care information, services and referral with and for First Nations Peoples with kidney disease. This project provides a working example of how to decolonise health service and education programs from the ground up.

Lung cancer is one of the most commonly diagnosed cancers in Canada and a leading cause of cancer mortality. Lung cancer also affects First Nations, Inuit and Métis peoples significantly in Canada, which deserves further investigation as there is a literature gap on this topic. We sought to develop a deeper understanding of lung cancer diagnosis, incidence, mortality, and survival in First Nations, Inuit, and Métis peoples in Canada. A systematic search was conducted in bibliographic databases to identify relevant studies published between January 2000 and March 2023. Articles were screened and assessed for relevance using the Population/ Concept/ Context (PCC) framework. A total of 22 articles were included in the final analysis, of which 13 were Inuit-specific, 7 were First Nations-specific, and 2 were Métis-specific. The literature suggests that comparative incidence, mortality, and relative risk of lung cancer is higher and survival is poorer in First Nations, Inuit and Métis peoples. Lung cancer also has varying impact on these population depending on sex, age, location and other factors. This review illustrates that more comprehensive quantitative and qualitative lung cancer research is essential to further identify the structural causes for the high incidence of the disease.

BACKGROUND: Aboriginal and Torres Strait Islander peoples are disproportionately impacted by type 2 diabetes. Continuous glucose monitoring (CGM) technology (such as Abbott Freestyle Libre 2, previously referred to as Flash Glucose Monitoring) offers real-time glucose monitoring that is convenient and easy to use compared to self-monitoring of blood glucose (SMBG). However, this technology\'s use is neither widespread nor subsidised for Aboriginal and Torres Strait Islander peoples with type 2 diabetes. Building on existing collaborations with a national network of Aboriginal and Torres Strait Islander communities, this randomised controlled trial aims to assess the effect of CGM compared to SMBG on (i) haemoglobin A1c (HbA1c), (ii) achieving blood glucose targets, (iii) reducing hypoglycaemic episodes and (iv) cost-effective healthcare in an Aboriginal and Torres Strait Islander people health setting.
METHODS: This is a non-masked, parallel-group, two-arm, individually randomised, controlled trial (ACTRN12621000753853). Aboriginal and Torres Strait Islander adults with type 2 diabetes on injectable therapy and HbA1c ≥ 7.5% (n = 350) will be randomised (1:1) to CGM or SMBG for 6 months. The primary outcome is change in HbA1c level from baseline to 6 months. Secondary outcomes include (i) CGM-derived metrics, (ii) frequency of hypoglycaemic episodes, (iii) health-related quality of life and (iv) incremental cost per quality-adjusted life year gained associated with the CGM compared to SMBG. Clinical trial sites include Aboriginal Community Controlled Organisations, Aboriginal Medical Services, primary care centres and tertiary hospitals across urban, rural, regional and remote Australia.
CONCLUSIONS: The trial will assess the effect of CGM compared to SMBG on HbA1c for Aboriginal and Torres Strait Islander people with type 2 diabetes in Australia. This trial could have long-term benefits in improving diabetes management and providing evidence for funding of CGM in this population.

UNASSIGNED: Indigenous Australians have higher rates of traumatic brain injury, with 74-90% of such injuries being concussion. This study explores concussion awareness and knowledge in Aboriginal Western Australians with high health literacy.
UNASSIGNED: Participants, aged 18-65 years, engaged in research topic yarning, and thematic analysis of the qualitative data then undertaken.
UNASSIGNED: There was awareness that direct head trauma can result in concussion, but a lack of differentiation between concussion and other head injuries. Knowledge was gained from sport, media or lived-experience. Symptom minimization and diversity of concussion symptoms prevented participants from seeking medical treatment. This was exacerbated by a mistrust of the medical system.
UNASSIGNED: Research findings highlight knowledge and service gaps where co-designed strategies can be targeted.
Despite higher injury rates in Indigenous Australians, literature relating to brain injuries such as concussion in these populations is lacking. This article provides information regarding awareness and knowledge of concussion in Aboriginal peoples with health or first responder experience. Through the process of yarning, 25 Aboriginal participants shared their awareness and knowledge of concussion. While there was good understanding of how concussion injury can occur, it was found that identification of concussion as a diagnosis is complex, and it is hard to differentiate from other conditions. Minimization of concussion symptoms was commonly reported, and multiple barriers to seeking healthcare after a potential concussion occurs were identified. Despite having health or first responder experience, participants reported their concussion knowledge was gained from community and televised sport, other aspects of media, and word of mouth. These results support the need for Indigenous Australian led and co-designed concussion education. They also support the need for further research in this space, targeting Indigenous Australian populations without high health literacy.

BACKGROUND: Indigenous people in Australia experience far poorer health than non-Indigenous Australians. A growing body of research suggests that Indigenous people who are strong in their cultural identity experience better health than those who are not. Yet little is known about how Indigenous people create and maintain strong cultural identities in the contemporary context. This paper explores how Indigenous people in south-eastern Australia create and maintain strong cultural identities to support their health and wellbeing.
METHODS: Data were collected from 44 Indigenous people living in the south-eastern Australian state of Victoria via yarning. Yarning is a cultural mode of conversation that privileges Indigenous ways of knowing, doing and being. Yarning participants were selected for their prominence within Victorian Indigenous health services and/or their prominence within the Victorian Indigenous community services sector more broadly. Due to the restrictions of COVID-19, yarns were conducted individually online via Zoom. Data were analysed employing constructivist grounded theory, which was the overarching qualitative research methodology.
RESULTS: All yarning participants considered maintaining a strong cultural identity as vital to maintaining their health and wellbeing. They did this via four main ways: knowing one\'s Mob and knowing one\'s Country; connecting with one\'s own Mob and with one\'s own Country; connecting with Community and Country more broadly; and connecting with the more creative and/or expressive elements of Culture. Importantly, these practices are listed in order of priority. Indigenous people who either do not know their Mob or Country, or for whom the connections with their own Mob and their own Country are weak, may therefore be most vulnerable. This includes Stolen Generations survivors, their descendants, and others impacted by historical and contemporary child removal practices.
CONCLUSIONS: The yarns reveal some of the myriad practical ways that Indigenous people maintain a strong cultural identity in contemporary south-eastern Australia. While programs designed to foster connections to Community, Country and/or Culture may benefit all Indigenous participants, those most disconnected from their Ancestral roots may benefit most. Further research is required to determine how best to support Indigenous Victorians whose connections to their own Mob and their own Country are unable to be (re)built.

UNASSIGNED: Congenital Long QT Syndrome (LQTS) is common in a First Nations community in Northern British Columbia due to the founder variant KCNQ1 p.V205M. Although well characterized molecularly and clinically in adults, no data have been previously reported on the pediatric population. The phenotype in adults has been shown to be modified by a splice site variant in KCNQ1 (p.L353L). The CPT1A p.P479L metabolic variant, also common in Northern Indigenous populations, is associated with hypoglycemia and infant death. Since hypoglycemia can affect the corrected QT interval (QTc) and may confer risk for seizures (also associated with LQTS), we sought to determine the effect of all three variants on the LQTS phenotype in children within our First Nations cohort.
UNASSIGNED: As part of a larger study assessing those with LQTS and their relatives in a Northern BC First Nation, we assessed those entering the study from birth to age 18 years. We compared the corrected peak QTc and potential cardiac events (syncope/seizures) of 186 children from birth to 18 years, with and without the KCNQ1 (p.V205M and p.L353L) and CPT1A variants, alone and in combination. Linear and logistic regression and student t-tests were applied as appropriate.
UNASSIGNED: Only the KCNQ1 p.V205M variant conferred a significant increase in peak QTc 23.8 ms (p < 0.001) above baseline, with females increased by 30.1 ms (p < 0.001) and males by 18.9 ms (p < 0.01). There was no evidence of interaction effects with the other two variants studied. Although the p.V205M variant was not significantly associated with syncope/seizures, the odds of having a seizure/syncope were significantly increased for those homozygous for CPT1A p.P479L compared to homozygous wild type (Odds Ratio [OR]3.0 [95% confidence interval (CI) 1.2-7.7]; p = 0.019).
UNASSIGNED: While the KCNQ1 p.V205M variant prolongs the peak QTc, especially in females, the CPT1A p.P479L variant is more strongly associated with loss of consciousness events. These findings suggest that effect of the KCNQ1 p.V205M variant is mild in this cohort, which may have implications for standard management. Our findings also suggest the CPT1A p.P479L variant is a risk factor for seizures and possibly syncope, which may mimic a long QT phenotype.
