Indigenous health part 1: determinants and disease patterns

Sámi community perspectives on the COVID-19 pandemic: a mixed methods case study in Arctic Sweden

The COVID-19 pandemic posed a grave threat not only to Indigenous people's health and well-being, but also to Indigenous communities and societies. This applies also to the Indigenous peoples of the Arctic, where unintentional effects of public health actions to mitigate the spread of virus may have long-lasting effects on vulnerable communities. This study aim was to identify and describe Sámi perspectives on how the Sámi society in Sweden was specifically affected by the pandemic and associated public health actions during 2020-2021. A mixed-method qualitative case study approach was employed, including a media scoping review and stakeholder interviews. The media scoping review included 93 articles, published online or in print, from January 2020 to 1 September 2021, in Swedish or Norwegian, regarding the pandemic-related impacts on Sámi society in Sweden. The review informed a purposeful selection of 15 stakeholder qualitative interviews. Thematic analysis of the articles and interview transcripts generated five subthemes and two main themes: "weathering the storm" and "stressing Sámi culture and society". These reflect social dynamics which highlight stressors towards, and resilience within, the Sámi society during the pandemic. The results may be useful when evaluating and developing public health crisis response plans concerning or affecting the Sámi society in Sweden.

Countering stereotypes: Exploring the characteristics of Aboriginal Australians who do not drink alcohol in a community representative sample

INTRODUCTION

Contrary to stereotypes, Aboriginal and Torres Strait Islander Australians are more likely to abstain from drinking than other Australians. We explored characteristics and experiences of Aboriginal and Torres Strait Islander Australians who do not drink alcohol.

METHOD

We conducted a cross-sectional, representative survey of 775 Aboriginal and Torres Strait Islander Australians (16+ years) in remote and urban South Australia. We explore correlates of not drinking alcohol using multi-level logistic regression. We describe reasons for non-drinking and harms participants experienced in past 12 months from others' drinking.

RESULTS

Non-drinking participants were more likely to be older (OR 1.35 [95% CI 1.21, 1.50] per decade) and unemployed (OR 2.72 [95% CI 1.77, 4.20]). Participants who spoke Aboriginal Australian languages at home were three times more likely to be lifetime abstainers from drinking (OR 3.07 [95% CI 1.52, 6.21]). Common reasons for not drinking alcohol were health and family. Most did not report harms from others' alcohol consumption (79.6%, 76.9%, urban and remote respectively). Stress from others' alcohol consumption was the most reported harm by non-drinkers (14.5% and 23.1%, urban and remote, respectively).

DISCUSSION AND CONCLUSIONS

Culture such as speaking Aboriginal Australian languages might have protective effects that promote abstaining but was rarely explicitly cited as a reason for not drinking. A greater understanding of local values held by people who do not drink alcohol could help inform health messaging and other interventions to reduce alcohol-related harms. Understanding local reasons for abstaining can help tailor health messaging to suit local contexts.

No improvement in AUDIT-C screening and brief intervention rates among wait-list controls following support of Aboriginal Community Controlled Health Services: evidence from a cluster randomised trial

BACKGROUND

While Aboriginal and Torres Strait Islander Australians are less likely to drink any alcohol than other Australians, those who drink are more likely to experience adverse alcohol-related health consequences. In a previous study, providing Aboriginal Community Controlled Health Services (ACCHSs) with training and support increased the odds of clients receiving AUDIT-C alcohol screening. A follow-up study found that these results were maintained for at least two years, but there was large variability in the effectiveness of the intervention between services. In this study, we use services that previously received support as a comparison group to test whether training and support can improve alcohol screening and brief intervention rates among wait-list control ACCHSs.

METHODS

Design: Cluster randomised trial using routinely collected health data.

SETTING

Australia.

CASES

Twenty-two ACCHSs that see at least 1000 clients a year and use Communicare as their practice management software. Intervention and comparator: After initiating support, we compare changes in screening and brief intervention between wait-list control services and services that had previously received support.

MEASUREMENT

Records of AUDIT-C screening and brief intervention activity in routinely collected data.

RESULTS

During the reference period we observed 357,257 instances where one of 74,568 clients attended services at least once during a two-monthly data extraction period. Following the start of support, the odds of screening (OR = 0.94 [95% CI 0.67, 1.32], p = 0.74, [Formula: see text]≈ 0.002) and brief intervention (OR = 1.43 [95% CI 0.69, 2.95], p = 0.34, [Formula: see text]≈ 0.002) did not improve for the wait-list control group, relative to comparison services.

CONCLUSIONS

We did not replicate the finding that support and training improves AUDIT-C screening rates with wait-list control data. The benefits of support are likely context dependent. Coincidental policy changes may have sensitised services to the effects of support in the earlier phase of the study. Then the COVID-19 pandemic may have made services less open to change in this latest phase. Future efforts could include practice software prompts to alcohol screening and brief intervention, which are less reliant on individual staff time or resources.

Colorectal cancer screening participation in First Nations populations worldwide: a systematic review and data synthesis

Background

First Nations populations have poorer colorectal cancer (CRC) survival compared to non-First Nations populations. Whilst First Nations populations across the world are distinct, shared experiences of discrimination and oppression contribute to persistent health inequities. CRC screening improves survival, however screening rates in First Nations populations are poorly described. This study seeks to define participation rates in CRC screening in First Nations populations worldwide.

Methods

A systematic literature search was conducted of PubMed, Embase, Cochrane Library, CINAHL, MEDLINE, grey literature, national registries and ClinicalTrials.gov. All sources were searched from their inception date to 18 February 2024. Studies were included if they reported CRC screening rates in adult (≥18 years) First Nations populations. We aimed to undertake a meta-analysis if there were sufficient data. Quality of papers were assessed using the Joanna Briggs Institute (JBI) appraisal tool. The study was registered with PROSPERO, CRD42020210181.

Findings

The literature search identified 1723 potentially eligible published studies. After review, 57 studies were included, 50 from the United States (US), with the remaining studies from Australia, Aotearoa New Zealand (NZ), Canada, Dominica and Guatemala. Additionally, eleven non-indexed reports from national programs in Australia and NZ were included. There were insufficient data to undertake meta-analysis, therefore a systematic review and narrative synthesis were conducted. CRC screening definitions varied, and included stool-based screening, sigmoidoscopy and colonoscopy. US First Nations screening rates ranged between 4.0 and 79.2%, Australia reported 10.6-35.2%, NZ 18.4-49%, Canada 22.4-53.4%, Guatemala 2.2% and Dominica 4.2%. Fifty-five studies were assessed as moderate or high quality and two as low quality.

Interpretation

Our findings suggested that there is wide variation in CRC screening participation rates across First Nations populations. Screening data are lacking in direct comparator groups and longitudinal outcomes. Disaggregation of screening data are required to better understand and address First Nations CRC outcome inequities.

Funding

None.

Breastfeeding rates of Aboriginal and Torres Strait Islander women in Australia: A systematic review and narrative analysis

BACKGROUND

Australian Aboriginal and Torres Strait Islander (referred to hereafter as Aboriginal) women breastfeed at lower rates than non-Aboriginal women, and rates vary across and within Aboriginal populations.

AIM

To determine rates of breastfeeding initiation and maintenance and compare individually collected survey data with existing routinely collected state and national breastfeeding data for Aboriginal women.

METHODS

CINAHL, Medline, EMBASE, SCOPUS, PsycINFO, and the Cochrane library were searched for peer-reviewed literature published between 1995 and 2021. Quantitative studies written in English and reporting breastfeeding for Aboriginal women or women having an Aboriginal infant were included. Screening and quality assessment included co-screening 10 % of papers. Two reviewers completed data extraction. A proportional meta-analysis was undertaken for breastfeeding initiation and narrative data synthesis used to summarise breastfeeding maintenance.

FINDINGS

The initial search identified 12,091 records, with 31 full text studies retrieved, and 27 reports from 22 studies met inclusion criteria. Breastfeeding initiation was 79 % (95 % CI 0.73, 0.85), however, rates were lower than non-Aboriginal women. Maintenance ranged between one week and five years. Rates and definitions varied significantly between studies, with inconsistencies in government collection and reporting of breastfeeding.

CONCLUSION

Significant variation in definitions and reporting make comparisons difficult. Breastfeeding rates were below recommended targets. Future pattern and trend analyses require standardised measures and definitions. Current collection and reporting of breastfeeding data, particularly routinely collected state-based data, is inadequate to present an accurate picture of current breastfeeding in Australia for Aboriginal women and infants, and to effectively inform interventions and policies.

Alcohol screening in 22 Australian Aboriginal Community Controlled Health Organisations: Clinical context and who is screened

INTRODUCTION

Alcohol screening among Indigenous Australians is important to identify individuals needing support to reduce their drinking. Understanding clinical contexts in which clients are screened, and which clients are more or less likely to be screened, could help identify areas of services and communities that might benefit from increased screening.

METHODS

We analysed routinely collected data from 22 Aboriginal Community Controlled Health Organisations Australia-wide. Data collected between February 2016 and February 2021 were analysed using R, and aggregated to describe screening activity per client, within 2-monthly extraction periods. Descriptive analyses were performed to identify contexts in which clients received an Alcohol Use Disorders Identification Test consumption (AUDIT-C) screen. Multi-level logistic regression determined demographic factors associated with receiving an AUDIT-C screen. Three models are presented to examine if screening was predicted by: (i) age; (ii) age and gender; (iii) age, gender and service remoteness.

RESULTS

We observed 83,931 occasions where AUDIT-C was performed at least once during a 2-monthly extraction period. Most common contexts were adult health check (55.0%), followed by pre-consult examination (18.4%) and standalone item (9.9%). For every 10 years' increase in client age, odds of being screened with AUDIT-C slightly decreased (odds ratio 0.98; 95% confidence interval [CI] 0.98, 0.99). Women were less likely to be screened with AUDIT-C (odds ratio 0.95; 95% CI 0.93, 0.96) than men.

DISCUSSION AND CONCLUSIONS

This study identified areas where alcohol screening can be increased (e.g., among women). Increasing AUDIT-C screening across entire communities could help reduce or prevent alcohol-related harms. Future Indigenous-led research could help identify strategies to increase screening rates.

A rural teledentistry care experience: a geriatric approach to assessing oral health status and treatment needs in older adults from a Mapuche community in Chile

Background

Limited attention has been given to oral health challenges faced by older Indigenous populations, especially in rural settings, where disparities exist. This study aims to assess oral health in a rural Mapuche community in southern Chile, utilizing geriatric technology support, and exploring the connection between geriatric health and oral well-being to fill a gap in this context.

Methods

A cross-sectional study was conducted involving 76 independent older adults from a rural Mapuche community who required dental care. Assessments were in a remote care setting gathering extensive data including comprehensive geriatric assessments, medical and dental conditions using a geriatric teledentistry platform (TEGO®). Statistical analysis involved descriptive analysis, logistic regression, and both multiple correspondence analysis and k-means cluster analysis.

Results

The sample comprised individuals with limited formal education and a high degree of vulnerability. Geriatric assessments unveiled cognitive deterioration, frailty, depression risk, and multimorbidity. A distribution of the DMFT index, number of remaining teeth, number of occluding pairs, number of teeth with restorative needs and other relevant clinical findings was conducted based on sociodemographic, and medical-geriatric-dental characteristics, and additionally, a Multinomial Logistic Regression Analysis of Dentition Variables in Relation to Geriatric Assessments was performed. The dental burden was substantial, with an average DMFT index of 25.96 (SD 4.38), high prevalence of non-functional dentition (89.3%), periodontal disease (83%), xerostomia (63.2%) and oral mucosal lesions (31.5%). Age, lower education, depression, daily medication number and sugary consumption frequency were associated with a decreased average number of teeth (p < 0.05). Multiple correspondence analysis and k-means cluster analysis identified 4 clusters, with the edentulous and functional dentition groups being the most distinct.

Conclusion

This study uncovers a substantial dental burden and intricate medical-geriatric conditions interlinked among Indigenous older adults in a rural Chilean Mapuche community. The implementation of a geriatric technological ecosystem in the community enabled the resolution of less complex oral health issues and facilitated remote consultations with specialists, reducing the necessity for travel to health centers. This underscores the need for innovative dental public health initiatives to address health disparities and improve the overall well-being of older Indigenous adults.

Inequalities in dental caries among Indigenous and non-Indigenous children in Australia: A literature review

Dental caries constitutes one of the most ubiquitous diseases in Australia, with Indigenous children presenting a notably higher prevalence than their non-Indigenous peers. This literature review aims to update the knowledge base developed by Christian and Blinkhorn in 2012, with a particular focus on the contemporary disparities in dental caries between Indigenous and non-Indigenous children. Our research strategy involved a thorough exploration of the Medline, PubMed, and Scopus databases to identify pertinent studies published between 2009 and 2022. Supplementary resources included various government websites and citation searches. We prioritised studies that focused on children aged 5-6 or 12 years-reflecting the World Health Organization's index ages for oral health-and that reported dental caries prevalence and experience indicators. Our review methodology was guided by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. The updated search, spanning 2009 to 2023, retrieved studies that reported caries estimates exclusively from 2009 to 2014. Within this period, the prevalence of dental caries in Indigenous children's primary teeth ranged between 52% and 77%, while the prevalence in permanent teeth varied from 36% to 60%. This updated review indicated that Indigenous children continue to experience caries at an approximately twice higher rate than non-Indigenous children, sustaining the persisting disparity in caries estimates. The findings from this review show that no discernible improvement in dental caries rates among Australian Indigenous children has been observed in comparison to the previous review; and that Indigenous children continue to experience both higher prevalence and severity of dental caries compared to non-Indigenous children.

Access to and Health Outcomes of Pediatric Solid Organ Transplantation for Indigenous Children in 4 Settler-colonial Countries: A Scoping Review

Solid organ transplantation (SOT) is considered the optimal treatment for children with end-stage organ failure; however, increased efforts are needed to understand the gap surrounding equitable access to and health outcomes of SOT for Indigenous children. This scoping review summarizes the literature on the characteristics of access to and health outcomes of pediatric SOT among Indigenous children in the settler-colonial states of Canada, Aotearoa New Zealand, Australia, and the United States. A search was performed on MEDLINE, EMBASE, PsycINFO, and CINAHL for studies matching preestablished eligibility criteria from inception to November 2021. A preliminary gray literature search was also conducted. Twenty-four studies published between 1996 and 2021 were included. Studies addressed Indigenous pediatric populations within the United States (n = 7), Canada (n = 6), Aotearoa New Zealand (n = 5), Australia (n = 5), and Aotearoa New Zealand and Australia combined (n = 1). Findings showed that Indigenous children experienced longer time on dialysis, lower rates of preemptive and living donor kidney transplantation, and disparities in patient and graft outcomes after kidney transplantation. There were mixed findings about access to liver transplantation for Indigenous children and comparable findings for graft and patient outcomes after liver transplantation. Social determinants of health, such as geographic remoteness, lack of living donors, and traditional spiritual beliefs, may affect SOT access and outcomes for Indigenous children. Evidence gaps emphasize the need for action-based initiatives within SOT that prioritize research with and for Indigenous pediatric populations. Future research should include community-engaged methodologies, situated within local community contexts, to inform culturally safe care for Indigenous children.

Health and well-being needs of Indigenous adolescents: a protocol for a scoping review of qualitative studies

INTRODUCTION

Improving the health of Indigenous adolescents is central to addressing the health inequities faced by Indigenous peoples. To achieve this, it is critical to understand what is needed from the perspectives of Indigenous adolescents themselves. There have been many qualitative studies that capture the perspectives of Indigenous young people, but synthesis of these has been limited to date.

METHODS AND ANALYSIS

This scoping review seeks to understand the specific health needs and priorities of Indigenous adolescents aged 10-24 years captured via qualitative studies conducted across Australia, Aotearoa New Zealand, Canada, the USA, Greenland and Sami populations (Norway and Sweden). A team of Indigenous and non-Indigenous researchers from these nations will systematically search PubMed (including the MEDLINE, PubMed Central and Bookshelf databases), CINAHL, Embase, Scopus, the Informit Indigenous and Health Collections, Google Scholar, Arctic Health, the Circumpolar Health Bibliographic Database, Native Health Database, iPortal and NZresearch.org, as well as specific websites and clearinghouses within each nation for qualitative studies. We will limit our search to articles published in any language during the preceding 5 years given that needs may have changed significantly over time. Two independent reviewers will identify relevant articles using a two-step process, with disagreements resolved by a third reviewer and the wider research group. Data will then be extracted from included articles using a standardised form, with descriptive synthesis focussing on key needs and priorities. This scoping review will be conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines.

ETHICS AND DISSEMINATION

Ethics approval was not required for this review. Findings will be disseminated via a peer-reviewed journal article and will inform a broader international collaboration for Indigenous adolescent health to develop evidence-based actions and solutions.

The TransFORmation of IndiGEnous PrimAry HEAlthcare Delivery (FORGE AHEAD): economic analysis

BACKGROUND

Indigenous populations have increased risk of developing diabetes and experience poorer treatment outcomes than the general population. The FORGE AHEAD program partnered with First Nations communities across Canada to improve access to resources by developing community-driven primary healthcare models.

METHODS

This was an economic assessment of FORGE AHEAD using a payer perspective. Costs of diabetes management and complications during the 18-month intervention were compared to the costs prior to intervention implementation. Cost-effectiveness of the program assessed incremental differences in cost and number of resources utilization events (pre and post). Primary outcome was all-cause hospitalizations. Secondary outcomes were specialist visits, clinic visits and community resource use. Data were obtained from a diabetes registry and published literature. Costs are expressed in 2023 Can$.

RESULTS

Study population was ~ 60.5 years old; 57.2% female; median duration of diabetes of 8 years; 87.5% residing in non-isolated communities; 75% residing in communities < 5000 members. Total cost of implementation was $1,221,413.60 and cost/person $27.89. There was increase in the number and cost of hospitalizations visits from 8/$68,765.85 (pre period) to 243/$2,735,612.37. Specialist visits, clinic visits and community resource use followed this trend.

CONCLUSION

Considering the low cost of intervention and increased care access, FORGE AHEAD represents a successful community-driven partnership resulting in improved access to resources.

A scoping review of Indigenous community-specific physical activity measures developed with and for Indigenous Peoples in Canada, Australia, and New Zealand

Historical factors including colonization and ongoing socioeconomic inequities impact Indigenous Peoples' ability to mitigate chronic disease risks such as achieving recommended physical activity (PA) levels. Reliably assessing, reflecting, and promoting PA participation among Indigenous Peoples may be impacted by a lack of culturally appropriate assessment methods and meaningful engagement with Indigenous communities throughout the research process. The objectives of this scoping review were to examine: (1) How PA research with Indigenous Peoples used community-specific PA measures developed with and/or for Indigenous Peoples in Canada, Australia, and New Zealand; and (2) How the studies utilized community-based participatory research (CBPR) principles to engage communities. A systematic search was conducted in four electronic databases (Web of Science, Medline, University of Saskatchewan Indigenous Portal, and ProQuest Dissertations and Theses Global). Thirty-one (n = 31) articles were identified and data extracted for narrative synthesis. Studies using community-specific PA measures have been increasing over time. Adapting questionnaires to traditional Indigenous activities such as cultural dances, ceremonies, and food-gathering activities were the most frequent adjustments undertaken to use community-specific measures. There are, however, gaps in research partnering with communities with only 6% of studies including all eight CBPR principles. Practical ways researchers can engage Indigenous communities and build capacity such as training and employing community members were highlighted. More needs to be done to facilitate community self-determination and develop long-term sustainable initiatives. Using culturally appropriate and relevant methodologies including partnering with Indigenous communities may help identification and implementation of culturally relevant and sustainable health-promoting initiatives.

Biocultural and social determinants of ill health and early mortality in a New Mexican paediatric autopsy sample

RESULTS.

Hispanic children have higher odds of growth stunting than non-Hispanic White children. Native American children die younger and have higher odds of respiratory diseases and porous lesions than Hispanic and non-Hispanic Whites. Rural/urban location does not significantly impact age at death, but housing type does. Individuals who lived in trailers/mobile homes had earlier ages at death. When intersections between housing type and housing location are considered, children who were poor and from impoverished areas lived longer than those who were poor from relatively well-off areas.

CONCLUSIONS.

Children's health is shaped by factors outside their control. The children included in this study embodied experiences of social and ELS and did not survive to adulthood. They provide the most sobering example of the harm that social factors (structural racism/discrimination, socioeconomic, and political structures) can inflict.

Peer and land-based approaches for fostering empowering and healthy relationships with Indigenous and northern young people in the Northwest Territories

Indigenous and Northern women in Canada experience high rates of intimate partner violence (IPV), and this is particularly true in the Northwest Territories (NWT). Adolescents are also at increased risk of IPV, which has far-reaching, lifelong effects. Indigenous youth are particularly vulnerable to IPV due to ongoing effects of intergenerational trauma caused by colonialism, racism and residential school legacies. We explored attitudes towards IPV and the healthy relationship knowledge, skills, and experiences among participants of Fostering Open eXpression among Youth (FOXY) and Strength, Masculinities, and Sexual Health (SMASH) Peer Leader Retreats in the NWT. Multi-method approaches included quantitative surveys youth completed before and immediately following retreats. Quantitative analysis from retreats (2018-2021) included 240 participants aged 12-19 (mean age 14.5) who reported ever having an intimate partner. Most were from the FOXY program (64.2%), Indigenous (69.6%) and heterosexual (66.4%). Qualitative methods included Focus Group Discussions (FGD) (n = 69) conducted with peer leaders and apprentices (n = 311) and youth and adult staff (n = 14 FGDs, n = 165 participants). We thematically analysed FGDs to explore healthy relationship knowledge and skills, alongside paired t-tests to examine pre/post retreat changes in attitudes towards IPV. Qualitative findings suggest that leadership and embodied learning were effective in equipping youth with violence prevention and healthy relationship skills. While young women were committed to sharing knowledge and skills about healthy relationships in their communities, young men resonated with values of respect and appreciated support to identify and express emotions. Participants across programmes demonstrated their belief that healthy intimate relationships have communal, relational and intergenerational benefits. Quantitatively, we found a statistically significant reduction in attitudes accepting of IPV among young women, but no changes were noted among young men. Findings contribute to emergent evidence on strengths-based, culturally-responsive IPV prevention programming. Components of effective IPV prevention programming with young men merit further exploration.

Variation in diurnal cortisol patterns among the Indigenous Shuar of Amazonian Ecuador

OBJECTIVES

The hypothalamic-pituitary-adrenal (HPA) axis and its primary end product, the glucocorticoid cortisol, are major components of the evolved human stress response. However, most studies have examined these systems among populations in high-income settings, which differ from the high pathogen and limited resource contexts in which the HPA axis functioned for most of human evolution.

METHODS

We investigated variability in diurnal salivary cortisol patterns among 298 Indigenous Shuar from Amazonian Ecuador (147 males, 151 females; age 2-86 years), focusing on the effects of age, biological sex, and body mass index (BMI) in shaping differences in diurnal cortisol production. Saliva samples were collected three times daily (waking, 30 minutes post-waking, evening) for three consecutive days to measure key cortisol parameters: levels at waking, the cortisol awakening response, the diurnal slope, and total daily output.

RESULTS

Age was positively associated with waking levels and total daily output, with Shuar juveniles and adolescents displaying significantly lower levels than adults (p < .05). Sex was not a significant predictor of cortisol levels (p > .05), as Shuar males and females displayed similar patterns of diurnal cortisol production across the life course. Moreover, age, sex, and BMI significantly interacted to moderate the rate of diurnal cortisol decline (p = .027). Overall, Shuar demonstrated relatively lower cortisol concentrations than high-income populations.

CONCLUSIONS

This study expands the documented range of global variation in HPA axis activity and diurnal cortisol production and provides important insights into the plasticity of human stress physiology across diverse developmental and socioecological settings.

Incidence of Stroke in Indigenous Populations of Countries With a Very High Human Development Index: A Systematic Review

BACKGROUND AND OBJECTIVES

Cardiovascular disease contributes significantly to disease burden among many Indigenous populations. However, data on stroke incidence in Indigenous populations are sparse. We aimed to investigate what is known of stroke incidence in Indigenous populations of countries with a very high Human Development Index (HDI), locating the research in the broader context of Indigenous health.

METHODS

We identified population-based stroke incidence studies published between 1990 and 2022 among Indigenous adult populations of developed countries using PubMed, Embase, and Global Health databases, without language restriction. We excluded non-peer-reviewed sources, studies with fewer than 10 Indigenous people, or not covering a 35- to 64-year minimum age range. Two reviewers independently screened titles, abstracts, and full-text articles and extracted data. We assessed quality using "gold standard" criteria for population-based stroke incidence studies, the Newcastle-Ottawa Scale for risk of bias, and CONSIDER criteria for reporting of Indigenous health research. An Indigenous Advisory Board provided oversight for the study.

RESULTS

From 13,041 publications screened, 24 studies (19 full-text articles, 5 abstracts) from 7 countries met the inclusion criteria. Age-standardized stroke incidence rate ratios were greater in Aboriginal and Torres Strait Islander Australians (1.7-3.2), American Indians (1.2), Sámi of Sweden/Norway (1.08-2.14), and Singaporean Malay (1.7-1.9), compared with respective non-Indigenous populations. Studies had substantial heterogeneity in design and risk of bias. Attack rates, male-female rate ratios, and time trends are reported where available. Few investigators reported Indigenous stakeholder involvement, with few studies meeting any of the CONSIDER criteria for research among Indigenous populations.

DISCUSSION

In countries with a very high HDI, there are notable, albeit varying, disparities in stroke incidence between Indigenous and non-Indigenous populations, although there are gaps in data availability and quality. A greater understanding of stroke incidence is imperative for informing effective societal responses to socioeconomic and health disparities in these populations. Future studies into stroke incidence in Indigenous populations should be designed and conducted with Indigenous oversight and governance to facilitate improved outcomes and capacity building.

Lip, oral and oropharyngeal cancer incidence among Aboriginal and Torres Strait Islander Peoples: First report from Australian population-based cancer registry, 1999-2018

BACKGROUND

The Australian Burden of Disease Study has shown that cancer is the single most important entity responsible for the greatest cause of health burden in Australia. Unfortunately, Aboriginal and Torres Strait Islander peoples experience a greater burden of this disease, with cancer of the lung, breast, bowel and prostrate being the most common. Lip, oral cavity and pharyngeal cancer incidence is rapidly rising globally and is now the sixth most common cancer in Australia. This paper aims to summarize, for the first time, the incidence and prevalence trends of lip, oral cavity and pharyngeal cancers in Aboriginal and Torres Strait Islander Australians.

METHODS

Data were obtained from the Australian Cancer Database (ACD), which is compiled at the Australian Institute of Health and Welfare (AIHW) from 1999 to 2018 to estimate the incidence and prevalence of certain head and neck cancers (ICD-10 codes C00-C10, C14). The other variables requested were age groups and sex.

RESULTS

Results were stratified by ICD-10 code, sex and age group at diagnosis and time period (i.e. grouped years of diagnosis). The total incidence of lip, oral cavity and pharyngeal cancers increased by 1.3 times from 1999 to 2008 (107/100 000) to 2009-2018 (135/100 000). The overall 5-year prevalence of lip, oral cavity and pharyngeal cancers was 0.17% (0.24% for men and 0.09% for women).

CONCLUSIONS

The significantly increased incidence of lip, oral cavity and pharyngeal cancers in Aboriginal and Torres Strait Islander peoples in Australia is concerning and should be explored. A targeted, comprehensive and culturally safe model of care for Aboriginal and Torres Strait Islander peoples with lip, oral cavity and pharyngeal cancers is imperative.

Risk Factors and Inequities in Transportation Injury and Mortality in the Canadian Census Health and Environment Cohorts (CanCHECs)

BACKGROUND

Road traffic injury contributes substantially to morbidity and mortality. Canada stands out among developed countries in not conducting a national household travel survey, leading to a dearth of national transportation mode data and risk calculations that have appropriate denominators. Since traffic injuries are specific to the mode of travel used, these risk calculations should consider travel mode.

METHODS

Census data on mode of commute is one of the few sources of these data for persons aged 15 and over. This study leveraged a national data linkage cohort, the Canadian Census Health and Environment Cohorts, that connects census sociodemographic and commute mode data with records of deaths and hospitalizations, enabling assessment of road traffic injury associations by indicators of mode of travel (commuter mode). We examined longitudinal (1996-2019) bicyclist, pedestrian, and motor vehicle occupant injury and fatality risk in the Canadian Census Health and Environment Cohorts by commuter mode and sociodemographic characteristics using Cox proportional hazards models within the working adult population.

RESULTS

We estimated positive associations between commute mode and same mode injury and fatality, particularly for bicycle commuters (hazard ratios for bicycling injury was 9.1 and for bicycling fatality was 11). Low-income populations and Indigenous people had increased injury risk across all modes.

CONCLUSIONS

This study shows inequities in transportation injury risk in Canada and underscores the importance of adjusting for mode of travel when examining differences between population groups.

Indigenous approaches to health assessment: a scoping review protocol

BACKGROUND

Health assessment tools developed using mainstream or Western concepts have been widely used in clinical practice worldwide. However, even culturally adapted or culturally based tools may not be relevant in other social contexts if they are grounded in Western beliefs and perspectives. The application of mainstream assessment tools, when used in Indigenous populations, can lead to the inappropriate application of normative data and inaccurate or biased diagnosis of conditions as Indigenous concepts of health differ from Western biomedical concepts of health. Thus, considering the need for culturally meaningful, sensitive, safe, and unbiased health assessment approaches and instruments over recent years, tools have been developed or adapted by and with Indigenous populations in Australia, Aotearoa/New Zealand, Canada, and the United States. However, there is no existing systematic or scoping review to identify the methods and approaches used in adapting or developing health assessment tools for use with the Indigenous population in Australia, Aotearoa/New Zealand, Canada, and the United States.

METHODS

In response to these gaps, we are working with a First Nations Community Advisory Group in Northern Ontario, Canada, to undertake a scoping review following the 2020 JBI methodology for scoping reviews. A systematic search will be conducted in PubMed, APA PsychINFO, CINAHL, MEDLINE, Web of Science, Bibliography of Native North Americans, Australian Indigenous Health info data set, and Indigenous Health Portal. Two reviewers will independently screen all abstracts and full-text articles for inclusion using criteria co-developed with an advisory group. We will chart the extracted information and summarize and synthesize the data. The summarized findings will be presented to a Community Advisory Group, including First Nations community partners, an Elder, and community members, and their feedback will be incorporated into the discussion section of the scoping review.

DISCUSSION

This scoping review involves iterative consultation with the Indigenous and non-Indigenous scholars, First Nations Community Advisory Group, and community partners throughout the research process. This review aims to summarize the evidence on standard ethical approaches and practices used in Indigenous research while adapting or developing health assessment tools. It will inform the larger study focused on developing an Indigenous Functional Assessment tool. Further, it will seek whether the Indigenous ways of knowing and equitable participation of Indigenous people and communities are incorporated in the Indigenous research process.

"'You Just Want to Give me Some Medicine and be on my Way': Preferences, Beliefs, and Experiences Related to Western Medication among Members of a State-Recognized Tribe"

Background: Native American/American Indian (NA/AI) people have higher rates of chronic disease, including substance use and mental health disorders, compared to White Americans. Though pharmaceuticals can be helpful in addressing many chronic healthcare conditions, many people do not take medications as prescribed. NA/AI identity has been found to be associated with lower rates of medication adherence compared to White Americans. Purpose: The purpose of this study is to better understand NA/AI women's perceptions, beliefs, and experiences related to medication. Methods: Thirty-one semi-structured interviews were conducted with NA/AI women from a state-recognized tribe located in the Gulf South. Interviews were transcribed and analyzed using a qualitative description approach. Results: Eighteen women discussed their experiences using medications when asked about their healthcare experiences. Participants identified the following themes in their discussion of medication: (a) Cost of Medication as a Barrier; (b) Negative Side Effects of Western Medication; (c) Fear of Resistance and Dependence; (d) Preference for Traditional Medicine or None; and (e) Lack of Communication around Medications from Providers. Conclusion: Our findings support the growing call for cultural safety within medical settings and integrating NA/AI conceptualizations of health and well-being and traditional practices into western healthcare settings to better support NA/AI people.

Redefining global cardiac surgery through an intersectionality lens

Although cardiovascular diseases are the leading cause of morbidity and mortality worldwide, six billion people lack access to safe, timely and affordable cardiac surgical care when needed. The burden of cardiovascular disease and disparities in access to care vary widely based on sociodemographic characteristics, including but not limited to geography, sex, gender, race, ethnicity, indigeneity, socioeconomic status and age. To date, the majority of cardiovascular, global health and global surgical research has lacked intersectionality lenses and methodologies to better understand access to care at the intersection of multiple identities and traditions. As such, global (cardiac) surgical definitions and health system interventions have been rooted in reductionism, focusing, at most, on singular sociodemographic characteristics. In this article, we evaluate barriers in global access to cardiac surgery based on existing intersectionality themes and literature. We further examine intersectionality methodologies to study access to cardiovascular care and cardiac surgery and seek to redefine the definition of 'global cardiac surgery' through an intersectionality lens.

Effectiveness of RADAR on diabetes processes of care for First Nations communities in Alberta, Canada

The epidemic of type-2 diabetes in First Nations communities is tragic. Culturally-appropriate approaches addressing multiple components, focusing beyond glycemic control, are urgently needed. Using an intention-to-treat framework, 13 processes of care indicators were assessed to compare proportions of patients who received care at baseline relative to 2-year follow-up. Clinical improvements were demonstrated across major process of care indicators (e.g. screening, education, and vaccination activities). We found RADAR improved reporting for most diabetes processes of care across seven FN communities and was effective in supporting diabetes care for FN communities, in Alberta Canada.

Experiences of Indigenous Patients Receiving Dialysis: Systematic Review of Qualitative Studies

RATIONALE & OBJECTIVE

Indigenous People suffer a high burden of kidney disease. Those receiving maintenance dialysis have worse outcomes compared with similarly treated non-Indigenous patients. We characterized the experiences of Indigenous patients receiving dialysis in British-colonized countries to gain insights into which aspects of kidney care may benefit from improvement.

STUDY DESIGN

A systematic review of published qualitative interview studies.

SETTING & STUDY POPULATIONS

Indigenous Peoples aged 18 years and over, receiving hemodialysis or peritoneal dialysis in British-colonized countries.

SELECTION CRITERIA FOR STUDIES

Search terms for Indigenous Peoples, dialysis, and qualitative research were entered into Medline, Embase, PsycINFO, and CINAHL and searched from inception to January 5, 2023.

DATA EXTRACTION

Characteristics of each study were extracted into Microsoft Excel for quality assessment.

ANALYTICAL APPROACH

Data were analyzed using thematic synthesis.

RESULTS

The analysis included 28 studies involving 471 participants from Australia, New Zealand, Canada, and the United States. We identified four themes: centrality of family and culture (continuing dialysis for family, gaining autonomy through shared involvement, balancing primary responsibility to care for family); marginalization due to structural and social inequities (falling through gaps in primary care intensifying shock, discriminated against and judged by specialists, alienated and fearful of hospitals, overwhelmed by travel, financial and regimental burdens); vulnerability in accessing health care (need for culturally responsive care, lack of language interpreters, without agency in decision-making, comorbidities compounding complexity of self-management); and distress from separation from community (disenfranchisement and sorrow when away for dialysis, inability to perpetuate cultural continuity, seeking a kidney transplant).

LIMITATIONS

We only included articles published in English.

CONCLUSIONS

Indigenous patients receiving dialysis experience inequities in health care that compound existing accessibility issues caused by colonization. Improving the accessibility and cultural responsiveness of dialysis and kidney transplant services in collaboration with Indigenous stakeholders holds promise to enhance the experience of Indigenous patients receiving dialysis.

PLAIN-LANGUAGE SUMMARY

Worldwide Indigenous populations suffer a high incidence of chronic disease leading to lower life expectancy, particularly for kidney disease, an insidious condition requiring long-term dialysis treatment. By listening to Indigenous dialysis patients' stories, we hoped to understand how to improve their experience. We gathered 28 qualitative research studies from four countries reporting Indigenous adults' experiences of dialysis. They described lacking awareness of kidney disease, poor access to health services, systemic racism, inadequate cultural safety, and being dislocated from family, community, and culture. These findings indicate that respectful collaboration with Indigenous Peoples to craft and implement policy changes holds promise to improve prevention, integrate culturally responsive health care practices, and provide better access to local dialysis services and opportunities for kidney transplants.

State of Cancer Control in South America: Challenges and Advancement Strategies

Cancer is a major public health problem in South America. The cancer mortality burden is increasing in the region due to its presentation at later stages, which is related to limited access to cancer care. This results in a noticeable inequity in provisions of cancer care including specialized screening programs, as well as cancer-related treatments such as personalized medicine, radiation therapy, palliative care, and survivorship services. Consequently, South America faces many challenges for cancer control, most of them deriving from a lack of funding and unequal distribution of resources and cancer services, affecting mostly the underserved populations in the region.

Ethnic differences in disability-free life expectancy and disabled life expectancy in older adults in Chile

BACKGROUND

Although about 10% of the Latin American population is indigenous, ethnic differences in disability-free life expectancy (DFLE) and life expectancy with disability (DLE) are unknown.

OBJECTIVE

To estimate disability-free life expectancy and disabled life expectancy among Mapuche (the largest indigenous group) and non-indigenous older adults aged 60 years or more in Chile.

METHOD

Disability was measured following a methodology that combines limitations of daily living, cognitive impairment and dependence previously validated in Chile. Finally, the DFLE was estimated using Sullivan's method combining life tables by ethnicity and disability proportions from the EDES survey designed for the study of ethnic differentials in health and longevity in Chile.

RESULTS

Non-Indigenous people have a higher total and Disability-free life expectancy compared to Mapuche people at all ages. While at age 60 a Mapuche expects to live 18.9 years, of which 9.4 are disability-free, a non-Indigenous expects to live 26.4 years, of which 14 are disability-free. In addition, although the length of life with disability increases with age for both populations, Mapuche who survive to age 80 or 90 expect to live 84% and 91% of their remaining life with disability, higher proportions compared to non-indigenous people (62.9% and 75%, respectively).

CONCLUSIONS

This is the first study addressing inequities in DFLE between the Mapuche and non-Indigenous population, reflected in lower total life expectancy, lower DFLE and higher DLE in Mapuche compared to the non-Indigenous population. Our results underscore the need for increased capacity to monitor mortality risks among older people, considering ethnic differences.

Ethnic differences in eating patterns and their associations with obesity among adults in West China

Despite observed ethnic differences in eating patterns and obesity, evidence in China is limited. This study examined ethnic differences in eating patterns and their associations with weight outcomes among multi-ethnic adults in West China. A cross-sectional survey collected self-reported data on demographics, eating behaviours, weight and height in 2021. Principal component analysis and multivariate regression were conducted to identify eating patterns and examine their associations with weight outcomes. In total, 4407 subjects aged ≥ 18 years were recruited across seven provinces in West China. Four eating patterns were identified: 'meat-lover' - characterised by frequent consumption of meat and dairy products, 'indulgent' - by frequent intakes of added salt, sugar, alcohol and pickled food, 'diversified-eating' - by frequently consuming food with diversified cooking methods and eating out and 'nutri-health-concerned' - by good food hygiene behaviours and reading food labels. Ethnic differences in eating patterns were observed. Compared with Han, Hui were less likely to exhibit meat-lover or diversified-eating patterns; Tibetans were less likely to have meat-lover or nutri-health-concerned patterns; Mongolians were more likely to have indulgent pattern. BMI was positively associated with meat-lover pattern in both genders (exp(β): 1·029; 95 % CI: 1·001, 1·058 for men; 1·018; 1·000, 1·036 for women) and negatively associated with nutri-health-concerned pattern in women (0·983; 0·966, 1·000). Mongolians were two times more likely to be overweight/obese than Han (OR: 3·126; 1·688, 5·790). Considerable ethnic differences existed in eating patterns in West China. Mongolians were more likely to be overweight/obese, which was associated with their indulgent eating patterns. Ethnic-specific healthy eating intervention programs are needed.

Measuring Mental Health Service Accessibility for Indigenous Populations: a Systematic Review

Indigenous populations have experienced inequality of accessing mental health services compared with their non-Indigenous counterparts, although the way of measuring mental health service accessibility for Indigenous populations is unclear. This systematic review examines measures of mental health service accessibility for Indigenous people, including the diversity of mental health services that are available to them and the barriers to accessing mental healthcare. Using a systematic search procedure, we identified 27 studies that explored Indigenous populations' mental health service access. Our review shows that 18 studies used interview-based methods to explore how Indigenous people use mental health services, and only nine studies used quantitative methods to measure the uptake of mental health services. While advanced methods for quantifying geographical access to healthcare services are widely available, these methods have not been applied in the current literature to explore the potential access to mental health services by Indigenous populations. This is partially due to limited understanding of how Indigenous populations seek mental healthcare, barriers that prevent Indigenous people from accessing diverse types of mental health services, and scarcity of data that are available to researchers. Future research could focus on developing methods to support spatially explicit measuring of accessibility to mental health services for Indigenous populations.

Climate change, biodiversity loss, and Indigenous Peoples' health and wellbeing: a systematic umbrella review protocol

BACKGROUND

Research that examines the intersections of Indigenous Peoples' health and wellbeing with climate change and biodiversity loss is abundant in the global scholarship. A synthesis of this evidence base is crucial in order to map current pathways of impact, as well as to identify responses across the global literature that advance Indigenous health and wellbeing, all while centering Indigenous voices and perspectives. This protocol details our proposed methodology to systematically conduct an umbrella review (or review of reviews) of the synthesized literature on climate change, biodiversity loss, and the health and wellbeing of Indigenous Peoples globally.

METHODS

A multidisciplinary team of Indigenous and non-Indigenous scholars will conduct the review, guided by an engagement process with an Indigenous Experts group. A search hedge will be used to search PubMed®, Scopus®, Web of Science™, CINAHL (via EBSCOHost®), and Campbell Collaboration databases and adapted for use in grey literature sources. Two independent reviewers will conduct level one (title/abstract) and level two (full-text) eligibility screening using inclusion/exclusion criteria. Data will be extracted from included records and analyzed using quantitative (e.g., basic descriptive statistics) and qualitative methods (e.g., thematic analysis, using a constant comparative method).

DISCUSSION

This protocol outlines our approach to systematically and transparently review synthesized literature that examines the intersections of climate change, biodiversity loss, and Indigenous Peoples' health and wellbeing globally.

SYSTEMATIC REVIEW REGISTRATION

This protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) on April 24, 2023 (registration number: CRD42023417060).

Sociodemographic patterning of dietary profiles among Inuit youth and adults in Nunavik, Canada: a cross-sectional study

OBJECTIVES

Country (traditional) foods are integral to Inuit culture, but market food consumption is increasing. The Qanuilirpitaa? 2017 Nunavik Health Survey (Q2017) reported similar country food consumption frequency compared to that in 2004; however, examining food items individually does not account for diet patterns, food accessibility, and correlations between food items. Our objective was to identify underlying dietary profiles and compare them across sex, age, ecological region, and food insecurity markers, given the links among diet, health, and sociocultural determinants.

METHODS

Food frequency and sociodemographic data were derived from the Q2017 survey (N = 1176). Latent profile analysis identified dietary profiles using variables for the relative frequencies of country and market food consumption first, followed by an analysis with those for country food variables only. Multinomial logistic regression examined the associations among dietary profiles, sociodemographic factors, and food insecurity markers (to disassociate between food preferences and food access).

RESULTS

Four overall dietary profiles and four country food dietary profiles were identified characterized by the relative frequency of country and market food in the diet. The patterns were stable across several sensitivity analyses and in line with our Inuit partners' local knowledge. For the overall profiles, women and adults aged 30-49 years were more likely to have a market food-dominant profile, whereas men and individuals aged 16-29 and 50+ years more often consumed a country food-dominant profile. In the country food profiles, Inuit aged 16-29 years were more likely to have a moderate country food profile whereas Inuit aged 50+ were more likely to have a high country food-consumption profile. A low country and market food-consumption profile was linked to higher prevalence of food insecurity markers.

CONCLUSION

We were able to identify distinct dietary profiles with strong social patterning. The profiles elucidated in this study are aligned with the impact of colonial influence on diet and subsequent country food promotion programs for Inuit youth. These profiles will be used for further study of nutritional status, contaminant exposure, and health to provide context for future public health programs.

Addressing experiences of trauma within Indigenous-focused substance use residential treatment: a systematic review and environmental scan

Indigenous individuals in Canada disproportionally experience higher rates of substance use concerns. This study examined clinical practices currently implemented with Indigenous-led residential treatment facilities to simultaneously address substance use and post-traumatic stress. A systematic review of relevant literature retrieved published approaches to address these concurrent disorders with Indigenous individuals. This review retrieved 35 sources related to trauma and substance use treatment among Indigenous individuals or communities. Among these sources, all leveraged cultural approaches as a dual treatment for trauma symptoms and substance use. Inconsistent results were reported among those sources (n = 3) who analyzed comparisons with wait-list controls or used randomized-controlled designs. Using culture-as-treatment was elaborated upon in the second goal of this study: an environmental scan of Indigenous-led treatment programs and qualitative interviews with 10 treatment center staff to understand how programs may address both substance use and traumatic symptoms among Indigenous-led substance use treatment centers across Canada. When we searched the websites of these centers, we found that approximately 38% (16 of 43) of treatment centers discussed implementing some form of treatment that addressed trauma symptoms in conjunction with primary substance use. Among the 10 staff participants, all discussed how trauma can impede client success in treatment, and ACE-specific programming is useful within their respective treatment programs. Results showed that when manualized treatments are used, they must be adapted to meet the specific needs of Indigenous communities, and culture-as-treatment is a popular approach among Indigenous-led treatment centers, particularly for addressing trauma symptoms.

Determinación social de la obesidad, la diabetes y la hipertensión arterial desde las narrativas de mujeres de una comunidad indígena en el sur de Morelos, México

OBJETIVO

comprender los procesos críticos (PC) de determinación social de la obesidad, la diabetes y la hipertensión (ODH) en una comunidad nahua de México.

METODOLOGÍA

estudio cualitativo de registros de un taller de fotovoz, donde las participantes fotografiaron su entorno y analizaron las causas y posibles soluciones a la ODH. Para analizar los PC de la ODH utilizamos como método la investigación narrativa y, como referente teórico, la epidemiología crítica.

RESULTADOS

la ODH se reproduce social e históricamente a través de PC destructivos vinculados con las relaciones de producción global y de género. Estas determinan modos de vida deteriorantes que limitan la atención a la salud, comprometen la salud mental, producen contaminación y diferenciación de uso de espacios, y reducen oportunidades para alimentarse nutritivamente y realizar actividad física. Todo ello se expresa como ODH y problemas de salud mental. Los PC protectores ante estas expresiones incluyen la atención estatal, las oportunidades de trabajo, y la promoción de dispositivos culturales y comunitarios.

CONCLUSIONES

nuestros resultados aportan a la discusión global sobre cómo las condiciones históricas de vida son parte de la determinación social de la ODH. Comprender los PC y sus expresiones locales puede orientarnos hacia la descolonización de la forma de pensar y hacer promoción de la salud.

Connecting the Dots of Care: A pilot study linking Aboriginal and/or Torres Strait Islander peoples with diabetes care in hospital, using hospital pharmacists

Background

Diabetes is common among Aboriginal and/or Torres Strait Islander peoples, yet often undetected in hospital.

Objective

To identify how urban hospital pharmacists can detect if Aboriginal and/or Torres Strait Islander patients have diabetes or a higher chance of getting diabetes.

Methods

A multi-methods study used data from patients, and researcher field notes. Aboriginal and/or Torres Strait Islander peoples admitted to hospital over 12-weeks (July-October 2021) were prospectively identified from admissions lists. A hospital pharmacist-researcher visited eligible patients. Consenting participants had their blood glucose and HbA1c checked. Participants with HbA1c > 6.5% (no known diabetes) or 7% (known diabetes) were referred for endocrinology review during their stay. Test results and resultant diabetes plan were shared with their general practitioner. Two days after discharge, participants were called to gauge views on their hospital-based diabetes care. Barcode technology recorded pharmacist time. Voice-recorded field notes were thematically analysed. Ethics approval was obtained.

Results

Seventy-two patients were eligible for inclusion, 67/72 (93%) consented to take part. Sixty-one (91%) patients returned a HbA1c < 6.5, of which, 4/61 (6.5%) returned a HbA1c, 6-6.4. They were contacted to yarn about diabetes prevention. Six of the 67 (9%) qualified for endocrine review, 5 had known diabetes, one newly diagnosed. None were known to endocrinology. All participants telephoned were satisfied with their hospital-based diabetes care. Pharmacist time for initial introductory yarn, consenting process, organisation of HbA1c and results discussion was 20 min or 40 min if referred for endocrine review. Field notes guided understanding of service implementation.

Conclusion

This novel pharmacist-led diabetes screening service for Aboriginal and/or Torres Strait Islander peoples appeared to provide a unique opportunity for screening and referral links in a holistic way. Future research is required to test this model by upscaling to include more pharmacists and other chronic disease screening and referral pathways.

Indigenous gender and wellness: a scoping review of Canadian research

This scoping review examined research publications related to health and/or wellness along with gender among Canadian Indigenous populations. The intent was to explore the range of articles on this topic and to identify methods for improving gender-related health and wellness research among Indigenous peoples. Six research databases were searched up to 1 February 2021. The final selection of 155 publications represented empirical research conducted in Canada, included Indigenous populations, investigated health and/or wellness topics and focused on gender. Among the diverse range of health and wellness topics, most publications focused on physical health issues, primarily regarding perinatal care and HIV- and HPV-related issues. Gender diverse people were seldom included in the reviewed publications. Sex and gender were typically used interchangeably. Most authors recommended that Indigenous knowledge and culture be integrated into health programmes and further research. More health research with Indigenous peoples must be conducted in ways that discern sex from gender, uplift the strengths of Indigenous peoples and communities, privilege community perspectives, and attend to gender diversity; using methods that avoid replicating colonialism, promote action, change stories of deficit, and build on what we already know about gender as a critical social determinant of health.

Mapping the knowledge structure and trends in Australian Indigenous health and wellbeing research from 2003 to 2022: a scientometric analysis

The health and wellbeing of Australian Indigenous peoples is a nationally sanctioned priority, but despite this, few studies have comprehensively analyzed the features and characteristics of the research in the field. In this regard, a comprehensive scientometric analysis and knowledge mapping to systematically summarize and discuss the current state of research, research trends, and emerging areas of research were conducted. Original articles and reviews published between 2003 and 2022 were obtained from the Web of Science Core Collection. CiteSpace and VOSviewer software were used to perform scientometric analysis and knowledge mapping. An examination of document and citation trends, authors, institutions, countries/regions, journals, and keywords was untaken, while co-citation, co-occurrence, and burst analysis provide insights and future development in this area. A total of 2,468 documents in this field were retrieved. A gradual increase in the number of documents over the past two decades is observed, with the number of documents doubling every ~7.5 years. Author Thompson SC and Charles Darwin University published the most documents, and 85.6% were affiliated with only Australian-based researchers. The Australian and New Zealand Journal of Public Health is the most prominent journal publishing in the field. The most commonly co-occurring keyword was "health," and the keyword "risk" had the longest citation burst. Five keyword clusters were identified; "cultural safety" was the largest. This study articulates the knowledge structure of the research, revealing a shift from population-level and data-driven studies to more applied research that informs Indigenous peoples health and wellbeing. Based on this review, we anticipate emergent research areas to (1) reflect a more comprehensive understanding of the multidimensional factors that shape Indigenous health and wellbeing; (2) move beyond a deficit-based perspective; (3) respect cultural protocols and protect the rights and privacy of Indigenous participants; (4) address racism and discrimination within the healthcare system; (5) foster respectful, equitable, and collaborative research practices with Indigenous peoples; (6) provide culturally appropriate and effective interventions for prevention, early intervention, and treatment; and (7) ensure equitable change in systems to enhance access, quality, and outcomes in health and wellbeing.

Financial burden of prostate cancer in the Iranian population: a cost of illness and financial risk protection analysis

BACKGROUND

Prostate cancer is the second most common cancer in males worldwide and the third most common among Iran's male population. However, there is a lack of evidence regarding its direct and indirect costs in low and middle-income countries. This study intends to bridge the gap using a cost of illness approach, assessing the costs of prostate cancer from the perspectives of patients, society, and the insurance system.

METHODS

Two hundred ninety seven patients were included in the study. Data for a 2-month period were obtained from patients registered at two hospitals (Tabriz, Tehran) in Iran in 2017. We applied a prevalence-based, bottom-up approach to assess the costs of the illness. We used the World Health Organization methods to measure the prevalence and investigate the determinants of catastrophic and impoverishing health expenditures.

RESULTS

We determined the total costs of the disease for the patients to be IRR 68 million (PPP $ 5,244.44). Total costs of the disease from the perspective of the society amounted to IRR 700,000 million (PPP $ 54 million). Insurance companies expended IRR 20 million (PPP $ 1,558.80) per patient. Our findings show that 31% of the patients incurred catastrophic health expenditure due to the disease. Five point forty-four percent (5.44%) of the patients were impoverished due to the costs of this cancer.

CONCLUSION

We found an alarmingly high prevalence of catastrophic health expenditures among prostate cancer patients. In addition, prostate cancer puts a substantial burden on both the patients and society.

Unintended consequences: Alcohol screening at urban Aboriginal Community Controlled Health Services was suppressed during COVID-19 lockdowns

INTRODUCTION

Regular screening for risky drinking is important to improve the health of Aboriginal and Torres Strait Islander Australians. We explored whether the rate of screening for risky drinking using the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) questions was disrupted at Aboriginal Community Controlled Health Services (ACCHS) during state-wide and territory-wide COVID-19 lockdowns in 2020.

METHODS

Retrospective analysis of screening data from 22 ACCHSs located in New South Wales, the Northern Territory, Queensland, South Australia, Victoria and Western Australia. These services provide holistic and culturally appropriate primary care. A multi-level Poisson regression, including AR(1) autocorrelation, was used to predict counts of AUDIT-C screening at ACCHSs.

RESULTS

AUDIT-C screening was suppressed during state-wide and territory-wide lockdowns in 2020 (incident rate ratio [IRR] 0.42 [0.29, 0.61]). The effect of lockdowns differed by service remoteness. While there was a substantial reduction in AUDIT-C screening for urban and inner regional services (IRR 0.25 [95% confidence interval (CI) 0.15, 0.42]), there was not a statistically significant change in screening at outer regional and remote (IRR 0.60 [95% CI 0.33, 1.09]) or very remote services (IRR 0.67 [95% CI 0.40, 1.11]).

DISCUSSION AND CONCLUSIONS

The COVID-19 lockdowns in Australia likely suppressed rates of screening for risky drinking in urban and inner regional regions. As harm from alcohol consumption may have increased during lockdowns, policymakers should consider implementing measures to enable screening for risky drinking to continue during future lockdowns.

Low rates of prescribing alcohol relapse prevention medicines in Australian Aboriginal Community Controlled Health Services

INTRODUCTION

Alcohol dependence is a chronic condition impacting millions of individuals worldwide. Safe and effective medicines to reduce relapse can be prescribed by general practitioners but are underutilised in the general Australian population. Prescription rates of these medicines to Aboriginal and Torres Strait Islander (First Nations) Australians in primary care are unknown. We assess these medicines in Aboriginal Community Controlled Health Services and identify factors associated with prescription.

METHODS

Baseline data (spanning 12 months) were used from a cluster randomised trial involving 22 Aboriginal Community Controlled Health Services. We describe the proportion of First Nations patients aged 15+ who were prescribed a relapse prevention medicine: naltrexone, acamprosate or disulfiram. We explore associations between receiving a prescription, a patient AUDIT-C score and demographics (gender, age, service remoteness) using logistic regression.

RESULTS

During the 12-month period, 52,678 patients attended the 22 services. Prescriptions were issued for 118 (0.2%) patients (acamprosate n = 62; naltrexone n = 58; disulfiram n = 2; combinations n = 4). Of the total patients, 1.6% were 'likely dependent' (AUDIT-C ≥ 9), of whom only 3.4% received prescriptions for these medicines. In contrast, 60.2% of those who received a prescription had no AUDIT-C score. In multivariate analysis, receiving a script (OR = 3.29, 95% CI 2.25-4.77) was predicted by AUDIT-C screening, male gender (OR = 2.24, 95% CI 1.55-3.29), middle age (35-54 years; OR = 14.41, 95% CI 5.99-47.31) and urban service (OR = 2.87, 95% CI 1.61-5.60).

DISCUSSION AND CONCLUSIONS

Work is needed to increase the prescription of relapse prevention medicines when dependence is detected. Potential barriers to prescription and appropriate ways to overcome these need to be identified.

Amplifying Older Aboriginal and Torres Strait Islander Women's Perspectives to Promote Digital Health Equity: Co-Designed Qualitative Study

BACKGROUND

Digital health is becoming ubiquitous, and we must ensure equity in access. Indigenous people across most high-income countries typically have not benefited as much as other citizens from usual health care systems and technologies. Despite Aboriginal and Torres Strait Islander people's clear interest in, and enthusiastic use of, new technologies, little research has examined the needs or interests of older Aboriginal and Torres Strait Islander women.

OBJECTIVE

This study prioritizes the perspectives of older Aboriginal and Torres Strait Islander women, tapping into their expertise associated with Indigenous ways of knowing, being, and doing, as well as their unique position within their families and communities, to design a model for using digital technologies to improve health for themselves and their families as well as their communities.

METHODS

Older Aboriginal and Torres Strait Islander women from 4 partner organizations were recruited for this study. This co-designed qualitative research included citizen scientists in shaping the protocol as well as collecting, analyzing, and interpreting data. We used yarning, an Indigenous research method validated for use in health research with Indigenous people and seen as respectful and culturally safe, as a primary research tool. The use of Indigenous methodologies and our iterative process enabled us to deeply explore and incorporate perspectives from all participants and ensure that the perspectives of Indigenous citizen scientists with lived experience were privileged. The data-checking methods also used a yarning methodology, which ensured that the findings and translational model derived from the findings were validated by the participants.

RESULTS

Participants comprised 24 Aboriginal and Torres Strait Islander women aged ≥41 years and including 3 generations that did not grow up with the internet: seniors, baby boomers, and Generation X. The key findings in this research were that older women use various digital technologies to improve health and well-being for themselves and their families as well as their communities. Older Aboriginal women want a culturally sensitive cyberspace that caters specifically to their needs and includes relevant content and functionality that are accessible and efficient. Our translational model highlights the conditions necessary for anyone to use digital health technologies, summarizes the essential elements needed to promote equity in digital health, and illuminates the unmet needs and requirements for older Aboriginal and Torres Strait Islander women to fully benefit from digital health technologies.

CONCLUSIONS

Health is a fundamental right. As we move toward greater reliance on digital health solutions, we must recognize and address the concerns of the smaller populations of people who differ in their needs. We must urgently address the financial, connectivity, and other limiting factors highlighted by older Aboriginal and Torres Strait Islander women in this study that limit equitable access to digital health tools.

Mental Health Challenges Among First Nations Adolescents Living Off-Reserve in Ontario, Canada

Limited data exist on the mental health challenges facing First Nations adolescents and the factors that modify these difficulties. The current study compared levels of common mental health challenges among 112 off-reserve First Nations and 3334 non-First Nations adolescents (12-17 years old) and examined the impact of maternal psychological distress on these mental health challenges. First Nations adolescents self-reported higher symptoms of conduct, oppositional-defiant, attention-deficit hyperactivity, major depressive, social phobia, generalized anxiety, and separation anxiety disorders and all associations remained statistically significant after adjusting for covariates. Moderation analyses found that increasing levels of maternal distress were associated more strongly with symptoms of oppositional defiant, attention-deficit hyperactivity, major depressive, and generalized anxiety disorders in First Nations adolescents. Future work aimed at improving the mental health of First Nations youth that focus on supporting these adolescents, and their mothers in particular, could result in substantial benefits.

Barriers and opportunities for improving dog bite prevention and dog management practices in northern Indigenous communities

Globally, people living in northern Indigenous communities are at higher risk of dog bites than the rest of the population living in North America, with annual incidence ranging from 0.61 to 59.6/10,000 inhabitants. Considering that rabies is endemic in wild canid populations in certain regions of the Arctic, the prevention of dog bites and the management of dog populations are of crucial importance for public health in these contexts. Most northern communities lack access to veterinary services, mainly due to their remote geographical location and to limited financial resources. Currently, northern Indigenous communities are using different approaches and strategies to prevent dog bites and manage dog populations, but the effectiveness of these approaches sometimes lacks evidence, and their low acceptability may affect their implementation. This study aims to describe (1) the current access and uses of veterinary services, and (2) the perceived barriers and opportunities related to dog population management practices currently implemented, or that could be implemented, in a Naskapi community and an Innu community located in northern Quebec (Canada). Quantitative data were collected through a survey to inhabitants on veterinary services (n = 122). Qualitative data were collected using individual interviews to inhabitants and health professionals to describe how dog population management measures were perceived, and to identify barriers and opportunities related to their implementation (n = 37). Descriptive and inferential analysis (quantitative data) and thematic analysis (qualitative data) were performed. Results show that the two main measures implemented at the time of the study - dog culling and short-duration veterinary clinics - were not perceived as fully acceptable and sustainable. Reinforcing access to veterinary services and other dog-related services, such as shelters and training programs on dogs, was identified as a need to improve dog bites prevention and dog population management in remote Indigenous communities. The implementation of animal health measures should be decided by concerned Indigenous communities to follow decolonial practices. It includes ensuring informed consent of dog owners, improving communication before, during and after interventions, separating veterinary services from rehoming and, most importantly giving back to Indigenous communities the complete leadership over animal health in their communities.

A systematic review of ageing in place among Indigenous People in Canada, USA, México, Chile and New Zealand

The ageing in place (AIP) model enjoys widespread recognition in gerontology and has been strongly encouraged through social policy. However, progress remains to be made in terms of analysing AIP for minority groups and groups with diverse life pathways in old age. This systematic review aims to identify studies that address the AIP model in indigenous communities, answering the following questions: In which geographical contexts and for which Indigenous Peoples have AIP been researched? Which physical dimensions are considered in the assessment of AIP? Which social dimensions are considered in the assessment of AIP? This systematic review applied the SALSA (Search, Appraisal, Synthesis and Analysis) method to AIP among Indigenous older adults on the Web of Science, PsycINFO, MEDLINE and Scopus digital platforms for publications from 2011 to 2021. We identified 12 studies conducted in five countries in North and South America and Oceania. The results show that the following elements of the physical environment are assessed: household, neighbourhood, local surroundings or reserve and native territories. Meanwhile, assessed elements of the social environment are as follows: personal characteristics, attachment to place, social networks, social participation and social policies. There is discussion of the need to develop AIP in order to promote successful ageing among Indigenous older adults.

What Kinds of Support are Alaska Native Youth and Young Adults Reporting? An Examination of Types, Quantities, Sources, and Frequencies of Support

American Indian and Alaska Native (AI/AN) youth, particularly males, experience disproportionately high rates of suicide compared to other young people in the United States. Therefore, enacting suicide prevention efforts for AI/AN youth is especially important. Since research shows that strengthening social, cultural, and emotional support can reduce suicide risk, many recent prevention efforts focus on these strategies. Yet, to reinforce and to extend the positive impact of these strategies for suicide risk reduction, we argue it is useful to identify baseline levels and other features of already-existing support. Toward this end, we describe the types (i.e., category), quantities (i.e., distribution and average number), sources (i.e., from whom), and frequencies (i.e., how often) of social support that AN young people report receiving, and we examine if these "support profiles" differ by age and sex. We use survey data from 165 ANs under age 30, collected as part of a participatory intervention study focused on Promoting Community Conversations About Research to End Suicide (PC CARES). We find that: 1) most ANs reported receiving nearly all supports, 2) compared with females, males reported receiving fewer supports on average, 3) family was the most selected support source, followed by close friends and service providers, and 4) family (e.g., parents, siblings, and grandparents) provided support regularly (i.e., monthly or more). Though our findings may suggest fruitful avenues for interventions targeted toward AN males, we discuss these findings in relation to the gendered nature of suicide prevention and assessment.

The Navajo Nation Healthy Diné Nation Act: Community Support of a 2% Tax on Unhealthy Foods

CONTEXT

The Healthy Diné Nation Act (HDNA) of 2014 included a 2% tax on foods of little-to-no-nutritious value ("junk foods") on the Navajo Nation. The law was the first ever in the United States and any Indigenous nation worldwide with a population at a high risk for common nutrition-related conditions. To date, research on community support for food tax legislation among Indigenous nations is entirely lacking.

OBJECTIVE

To assess the extent of support for the HDNA and factors associated with support including sociodemographic variables, knowledge of the HDNA, nutrition intake, and pricing preferences.

DESIGN

Cross-sectional survey.

SETTING

The Navajo Nation.

PARTICIPANTS

A total of 234 Navajo Nation community members across 21 communities.

OUTCOME MEASURES

The percentage of participants who were supportive of the HDNA.

RESULTS

Participants were 97% Navajo, on average middle-aged, 67% reported an income below $25 000 annually, and 69.7% were female. Half of the respondents said they "support" (37.4%) or "strongly support" (13.0%) the tax, while another 35% of people said they were neutral or somewhat supportive; 15% did not support the tax. Participants with higher income ( P = .025) and education ( P = .026) and understanding of the legislation ( P < .001 for "very well" vs "not at all") had increased odds of greater support, as did people who believed that the HDNA would make Navajo people healthier (vs not, P < .001). Age, gender, language, and reported nutrition intake (healthy or unhealthy) were not associated with HDNA support, but participants willing to pay 5% or 12%-15% higher prices for fast food and soda had increased odds of greater support ( P values range from .023 to <.001).

CONCLUSIONS

The majority of Navajo community members surveyed were moderately supportive of the Navajo Nation tax on unhealthy foods. Higher income and education and understanding of the law were associated with greater support, but nutrition intake was not.

Indigenous communities and influenza: protocol for a systematic review and meta-analysis

BACKGROUND

Several studies have documented that specific Indigenous groups have been disproportionately affected by previous pandemics. The objective of this paper is to describe the protocol to be used in a review and meta-analysis of the literature on Indigenous groups and influenza. Using this protocol as a guide, a future study will provide a comprehensive historical overview of pre-COVID impact of influenza on Indigenous groups by combining data from the last five influenza pandemics and seasonal influenza up to date.

METHODS/PRINCIPLE FINDINGS

The review will include peer-reviewed original studies published in English, Spanish, Portuguese, Swedish, Danish, and Norwegian. Records will be identified through systematic literature search in eight databases: Embase, MEDLINE, CINAHL, Web of Science, Academic Search Ultimate, SocINDEX, ASSIA, and Google Scholar. Results will be summarized narratively and using meta-analytic strategies.

DISCUSSION

To our knowledge, there is no systematic review combining historical data on the impact of both seasonal and pandemic influenza on Indigenous populations. By summarizing results within and across Indigenous groups, different countries, and historical periods, as well as research in six different languages, we aim to provide information on how strong the risk for influenza is among Indigenous groups and how consistent this risk is across groups, regions, time, and seasonal versus the specific pandemic influenza strains.

What Is Wellbeing, and What Is Important for Wellbeing? Indigenous Voices from across Canada

Indigenous peoples' perceptions of wellbeing differ from non-Indigenous constructs. Thus, it is imperative to recognize that Indigenous peoples will conceptualize wellbeing from their perspectives and set their own wellbeing priorities. In keeping with this viewpoint, the aims of the present study were to conceptualize wellbeing and determine what was (and is) important for wellbeing from Canadian Indigenous peoples' perspectives. In this paper, we take a partnership approach based on the elements of respect, equity, and empowerment. One primary data source and two existing data sources were examined and analyzed thematically utilizing a combination approach of deductive and inductive coding. Indigenous leadership and organizations viewed wellbeing holistically and conceptualized wellbeing multidimensionally. From across Canada, wellbeing was communicated as physical, economic, political, social, and cultural. The scaling of wellbeing represented a collectivist perspective, and land was the connecting thread between all types of wellbeing, being a place to practice cultural traditions, reassert one's Indigenous identity, find solace, and pass on Indigenous knowledge and languages. Although wellbeing was discussed in the context of the individual, family, community, and nation, wellbeing was most often discussed at the cultural level by regional and national Indigenous leadership and organizations. Even in acknowledging the great cultural diversity among Canadian Indigenous nations, four concordant themes were identified regionally and nationally, with respect to what was important for cultural wellbeing: land and water, sustainability, and inherent obligations; being on the land, and indigenous languages and knowledge systems; sustainable development; and meaningful involvement in decision-making, and free, prior, and informed consent. Taking into account these themes is foundational for any interaction with Indigenous peoples, especially in the context of land, culture, and development. There needs to be a new beginning on the journey to reconciliation with land and cultural wellbeing at the forefront.

Incremental effectiveness of 23-valent pneumococcal polysaccharide vaccine against pneumonia hospitalisation among Australian Indigenous children: A record linkage study

BACKGROUND

The impact of pneumococcal conjugate vaccines (PCVs) on pneumonia in children is well-documented but data on 23-valent pneumococcal polysaccharide vaccine (PPV23) are lacking. Between 2001 and 2011, Indigenous children in Western Australia (WA) were recommended to receive PPV23 at 18-24 months of age following 3 doses of 7-valent PCV. We evaluated the incremental effectiveness of PPV23 against pneumonia hospitalisation.

METHODS

Indigenous children born in WA between 2001 and 2012 who received PCV dose 3 by 12 months of age were followed from 18 to 60 months of age for the first episode of pneumonia hospitalisation (all-cause and 3 subgroups: presumptive pneumococcal, other specified causes, and unspecified). We used Cox regression modelling to estimate hazard ratios (HRs) for pneumonia hospitalisation among children who had, versus had not, received PPV23 between 18 and 30 months of age after adjustment for confounders.

RESULTS

11,120 children had 327 first episodes of all-cause pneumonia hospitalisation, with 15 (4.6%) coded as presumptive pneumococcal, 46 (14.1%) as other specified causes and 266 (81.3%) unspecified. No statistically significant reduction in all-cause pneumonia was seen with PPV23 (HR 1.11; 95% CI: 0.87-1.43), but the direction of the association differed for presumptive pneumococcal (HR 0.47; 95% CI: 0.16-1.35) and specified (HR 0.89; 95% CI: 0.49-1.62) from unspecified causes (HR 1.13; 95% CI: 0.86-1.49). During the baseline period before PPV23 vaccination (12-18 months), all-cause pneumonia risk was higher among PPV23-vaccinated than unvaccinated children (RR: 1.73; 95% CI: 1.30-2.28).

CONCLUSION

In this high-risk population, no statistically significant incremental effect of a PPV23 booster at 18-30 months was observed against hospitalised all-cause pneumonia or the more specific outcome of presumptive pneumococcal pneumonia. Confounding by indication may explain the slight trend towards an increased risk against all-cause pneumonia. Larger studies with better control of confounding are needed to further inform PPV23 vaccination.

Water Insecurity and Maternal Health Among Haudenosaunee Women in Canada

Water is central to Haudenosaunee knowledge, philosophy, and culture. The health of Haudenosaunee mothers is tied to that of water. Today, the lack of access to reliable drinking water for Six Nations is a significant health concern. Technical measurement of water advisories in Canada fails to understand the interwoven relationship that Haudenosaunee women have with water. Highlighting the voices of 55 Haudenosaunee women, we provide expanded definitions of water insecurity and maternal health to include more-than-human beings. This comprehensive understanding of water insecurity and health shapes SN mothers' experiences with water in a settler colonial state, affecting their holistic wellbeing.

Exploring barriers to accessing healthcare services for older indigenous people in the Chittagong Hill Tract, Bangladesh

We aim to investigate the obstacles faced by elderly indigenous individuals in the Chittagong Hill Tracts, Bangladesh when accessing healthcare services. A qualitative research approach was utilized, and data collection was carried out in three distinct regions of the aforementioned area. A total of 30 in-depth, semi-structured interviews and participant observations were conducted to achieve the research objectives. Thematic analysis utilizing both a deductive and inductive approach was employed to analyze the data. The Granheim method and Nvivo-12 software were utilized to process, analyze and code the data. The study's findings indicate that a lack of knowledge about healthcare needs, geographical barriers, poor financial conditions, higher cost of medical services, scarcity of hospitals nearby and communication barriers all contribute to inadequate access to healthcare services. By recognizing the factors that impede access to healthcare services in this region, this study offers valuable insight for policymakers and healthcare providers on how to enhance healthcare services for the indigenous population, especially the elderly. Furthermore, the government can adopt a more efficient approach to include these elderly individuals in various social safety net programs.
