RESUMEN
OBJECTIVES: This study tested the association between neuroticism and six cognitive measures, and examined the potential mediating roles of social connection (social isolation and loneliness) among middle-aged and older adults. METHODS: This cross-sectional study was a secondary analysis of the Canadian Longitudinal Study on Aging (CLSA) Comprehensive Cohort, a sample of Canadians aged 45-85 years at baseline. Respondents with data collected at the first follow-up, between 2015 and 2018, were included (n = 27,765). Structural equation modelling was used to assess the association between neuroticism and six cognitive measures (Rey Auditory Verbal Learning Test immediate recall and delayed recall, Animal Fluency Test, Mental Alternation Test, Controlled Oral Word Association Test and Stroop Test interference ratio), with direct and indirect effects (through social isolation and loneliness). All analyses were stratified by sex, including females (n = 14,133) and males (n = 13,632). RESULTS: In unadjusted models, there was evidence of associations between neuroticism and all cognitive measures, except the Stroop Test interference ratio, suggesting higher neuroticism was associated with lower scores on memory and executive function tests. In the models of these other five outcomes, there was consistent evidence of indirect effects (through social isolation and loneliness) and, in some cases, direct effects. The results are discussed in context with limitations, including the use of cross-sectional design and alternative hypotheses to explain the association between personality and cognition. CONCLUSION: Among middle-aged and older adults, for both males and females, the findings suggest that the association between neuroticism and cognitive outcomes may be mediated by aspects of social connection.

BACKGROUND: As First Nations Peoples are a priority focus of Canada's commitment to eliminating hepatitis C virus (HCV) as a public health threat, understanding individuals' progression from diagnosis to cure can guide prioritization of elimination efforts. We sought to characterize and identify gaps in the HCV care cascade for Status First Nations peoples in Ontario. METHODS: In this retrospective cohort study, a partnership between the Ontario First Nations HIV/AIDS Education Circle and academic researchers, HCV testing records (1999-2018) for Status First Nations peoples in Ontario were linked to health administrative data. We defined the cascade of care as 6 stages, as follows: tested positive for HCV antibody, tested for HCV RNA, tested positive for HCV RNA, HCV genotyped, initiated treatment and achieved sustained viral response (SVR). We mapped the care cascade from 1999 to 2018, and estimated the number and proportion of people at each stage. We stratified analyses by sex, diagnosis date and location of residence. We used Cox regression to analyze the secondary outcomes, namely the associations between undergoing HCV RNA testing and initiating treatment, and demographic and clinical predictors. RESULTS: By Dec. 31, 2018, 4962 people tested positive for HCV antibody. Of those testing positive, 4118 (83.0%) were tested for HCV RNA, with 2480 (60.2%) testing positive. Genotyping was completed in 2374 (95.7%) of those who tested positive for HCV RNA, with 1002 (42.2%) initiating treatment. Nearly 80% (n = 801, 79.9%) of treated people achieved SVR, with 34 (4.2%) experiencing reinfection or relapse. Undergoing testing for HCV RNA was more likely among people in older age categories (within 1 yr of antibody test; adjusted hazard ratio [HR] 1.30, 95% confidence interval [CI] 1.19-1.41, among people aged 41-60 yr; adjusted HR 1.47, 95% CI 1.18-1.81, among people aged > 60 yr), those living in rural areas (adjusted HR 1.20, 95% CI 1.10-1.30), those with an index date after Dec. 31, 2013 (era of treatment with direct-acting antiviral regimens) (adjusted HR 1.99, 95% CI 1.85-2.15) and those with a record of substance use or addictive disorders (> 1 yr after antibody test; adjusted HR 1.38, 95% CI 1.18-1.60). Treatment initiation was more likely among people in older age categories at index date (adjusted HR 1.32, 95% CI 1.15-1.50, among people aged 41-60 yr; adjusted HR 2.62, 95% CI 1.80-3.82, among people aged > 60 yr) and those with a later diagnosis year (adjusted HR 2.71, 95% CI 2.29-3.22). INTERPRETATION: In comparison with HCV testing and diagnosis, a substantial gap in treatment initiation remains among Status First Nations populations in Ontario. Elimination efforts that prioritize linkage to care and integration with harm reduction and substance use services are needed to close gaps in HCV care among First Nations populations in Ontario.

First Nations in Ontario are building capacity to leverage health services data in Ontario to provide robust, First Nations-driven health evidence. Beyond providing evidence, population health research processes must involve diverse First Nations' perspectives, collective capacity building and translation of research findings into action through integrated and community engaged knowledge translation and exchange (KTE) approaches. Suggested ways include integrating stories and traditional knowledge, prioritizing gatherings and establishing an enduring commitment to action. To effectively support First Nations' self-determination and sovereignty, First Nations' principles of ownership, control, access and possession (OCAP®) in research could be expanded to include "action" (OCAPA).

BACKGROUND: Indigenous people worldwide are disproportionately affected by diabetes and its complications. We aimed to assess the monitoring, treatment and control of blood glucose and lipids in First Nations people in Ontario. METHODS: We conducted a longitudinal population-based study using administrative data for all people in Ontario with diabetes, stratified by First Nations status. We assessed age- and sex-specific rates of completion of recommended monitoring for low-density lipoprotein (LDL) and glycated hemoglobin (A1c) from 2001/02 to 2014/15. We used data from 2014/15 to conduct a cross-sectional analysis of rates of achievement of A1c and LDL targets and use of glucose-lowering medications. RESULTS: The study included 22 240 First Nations people and 1 319 503 other people in Ontario with diabetes. Rates of monitoring according to guidelines were 20%-50% for A1c and 30%-70% for lipids and were lowest for younger First Nations men. The mean age- and sex-adjusted A1c level was higher among First Nations people than other people (7.59 [95% confidence interval (CI) 7.57 to 7.61] v. 7.03 [95% CI 7.02 to 7.03]). An A1c level of 8.5% or higher was observed in 24.7% (95% CI 23.6 to 25.0) of First Nations people, compared to 12.8% (95% CI 12.1 to 13.5) of other people in Ontario. An LDL level of 2.0 mmol/L or less was observed in 60.3% (95% CI 59.7 to 61.6) of First Nations people, compared to 52.0% (95% CI 51.1 to 52.9) of other people in Ontario. Among those aged 65 or older, a higher proportion of First Nations people than other Ontarians were using insulin (28.1% v. 15.1%), and fewer were taking no medications (28.3% v. 40.1%). INTERPRETATION: As of 2014/15, monitoring and achievement of glycemic control in both First Nations people and other people in Ontario with diabetes remained suboptimal. Interventions to support First Nations patients to reach their treatment goals and reduce the risk of complications need further development and study.

BACKGROUND: Diabetes mellitus is an established health concern in First Nations communities and is associated with complex influences of colonization. This study, a partnership between First Nations and academic researchers, was undertaken to determine patterns of diabetes prevalence, incidence and mortality in Ontario. METHODS: Using health services and population data from Ontario for 1995 to 2014, linked with the federal Indian Register, we calculated age- and sex-adjusted annual estimates of diabetes prevalence, incidence and mortality for First Nations people (living within and outside First Nations communities) and other people in Ontario. We also examined age- and sex-specific crude diabetes prevalence. RESULTS: Between 1995 and 2014, the prevalence of diabetes increased and the incidence decreased somewhat in all populations. Both prevalence and incidence were substantially higher among First Nations people than among other people in Ontario. In particular, First Nations women had higher prevalence than other women (4.2% v. 1.6% for ages 20-34 yr and 17.6% v. 6.0% for ages 35-49 yr). The lifetime risk of diabetes was higher among First Nations people than among other people in Ontario (57.0%, 95% confidence interval [CI] 56.3%-57.6% v. 44.5%, 95% CI 44.4%-44.6%). Over time, all-cause mortality for those with diabetes declined but remained consistently higher for First Nations people than for other people in Ontario. INTERPRETATION: Diabetes is more common among First Nations people than among other people in Ontario, particularly at younger ages and in women. First Nations-led approaches to address the high prevalence of diabetes in younger First Nations women have the potential to improve metabolic health across generations.

BACKGROUND: Indigenous people continue to experience high rates of multiple chronic conditions (MCC) at younger ages than other populations, resulting in an increase in health and social care needs. Those who provide services designed to address MCC for Indigenous communities require synthesized information to develop interventions that meet the needs of their older adult population. This review seeks to answer the research question: What are the health and social care needs, priorities and preferences of Indigenous older adults (living outside of long-term care settings) with MCC and their caregivers? METHODS: A scoping review, guided by a refinement of the Arksey & O'Malley framework, was conducted. Articles were included if the authors reported on health and social care needs and priorities of older Indigenous adults. We also included articles that focused on Indigenous conceptions of wellness, resilience, well-being, and/or balance within the context of aging, and articles where authors drew from Indigenous specific worldviews, ways of knowing, cultural safety, cultural competence, cultural appropriateness, cultural relevance and community needs. RESULTS: This scoping review included 9 articles that were examined using an Indigenous determinants of health (IDH) theoretical framework to analyze the needs of older adults and CGs. Five areas of needs were identified: accessible health services; building community capacity; improved social support networks; preservation of cultural values in health care; and wellness-based approaches. CONCLUSION: The review highlights key determinants of health that influenced older adults' needs: education and literacy, ethnicity, and social support/network (proximal); health promotion and health care (intermediate); and a combination of historical and contemporary structures (distal). The findings highlight the importance of local Indigenous knowledge and perspectives to improve accessibility of culturally relevant health and social services.

Indigenous data governance principles assert that Indigenous communities have a right to data that identifies their people or communities, and a right to determine the use of that data in ways that support Indigenous health and self-determination. Indigenous-driven use of the databases held at the Institute for Clinical Evaluative Sciences (ICES) has resulted in ongoing partnerships between ICES and diverse Indigenous organizations and communities. To respond to this emerging and complex landscape, ICES has established a team whose goal is to support the infrastructure for responding to community-initiated research priorities. ICES works closely with Indigenous partners to develop unique data governance agreements and supports processes, which ensure that ICES scientists must work with Indigenous organizations when conducting research that involves Indigenous peoples.

OBJECTIVE: Late cancellation of surgery cases imposes significant emotional distress on the patient and their family and results in wasted resources, including loss of operating room and personnel time. This study was designed to determine the causes of cancellation, preventability, total operating room time, and postoperative destination. DESIGN: This study was a retrospective review of the 43 cardiac surgical cases that were cancelled while the patient was in the operating room (OR) but prior to surgical incision. SETTING: The cases were performed at the Massachusetts General Hospital, a teaching hospital of Harvard Medical School. PARTICIPANTS: Forty-three out of 5,110 scheduled cardiac cases were identified that were cancelled after the patient had entered the operating room between January 1, 2010 and December 31, 2013. INTERVENTIONS: No interventions were made. This was a retrospective study. MEASUREMENTS AND MAIN RESULTS: The most common causes of cancellation included a change in the patient's health status (44%), problems associated with central catheter placement (18.6%), and unsatisfactory donor organs for planned transplantation (12%). The majority were inpatients (65%) prior to the procedure. The cumulative OR time for all cancelled cases was 5,374 minutes (89 hours and 34 minutes). CONCLUSIONS: The reason for cancellation, preventability, total operating room time, and postoperative destination were determined. The information can be utilized to decrease the number of future cancellations.

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.

Indigenous Peoples' right to sovereignty forms the foundation for advocacy and actions toward greater Indigenous self-determination and control across a range of domains that impact Indigenous Peoples' communities and cultures. Declarations for sovereignty are rising throughout Indigenous communities and across diverse fields, including Network Sovereignty, Food Sovereignty, Energy Sovereignty, and Data Sovereignty. Indigenous Research Sovereignty draws in the sovereignty discourse of these initiatives to consider their applications to the broader research ecosystem. Our exploration of Indigenous Research Sovereignty, or Indigenous self-determination in the context of research activities, has been focused on the relationship between Indigenous Data Sovereignty and efforts to describe Indigenous Peoples' Rights in data.
RESUMEN
INTRODUCTION: The aim of our study was to assess the initial impact of COVID-19 on total publicly-funded direct healthcare costs and health services use in two Canadian provinces, Ontario and British Columbia (BC). METHODS: This retrospective repeated cross-sectional study used population-based administrative datasets, linked within each province, from January 1, 2018 to December 27, 2020. Interrupted time series analysis was used to estimate changes in the level and trends of weekly resource use and costs, with March 16-22, 2020 as the first pandemic week. Also, in each week of 2020, we identified cases with their first positive SARS-CoV-2 test and estimated their healthcare costs until death or December 27, 2020. RESULTS: The resources with the largest level declines (95% confidence interval) in use in the first pandemic week compared to the previous week were physician services [Ontario: -43% (-49%,-37%); BC: -24% (-30%,-19%) (both p<0.001)] and emergency department visits [Ontario: -41% (-47%,-35%); BC: -29% (-35%,-23%) (both p<0.001)]. Hospital admissions declined by 27% (-32%,-23%) in Ontario and 21% (-26%,-16%) in BC (both p<0.001). Resource use subsequently rose but did not return to pre-pandemic levels. Only home care and dialysis clinic visits did not significantly decrease compared to pre-pandemic. Costs for COVID-19 cases represented 1.3% and 0.7% of total direct healthcare costs in 2020 in Ontario and BC, respectively. CONCLUSIONS: Reduced utilization of healthcare services in the overall population outweighed utilization by COVID-19 patients in 2020. Meeting the needs of all patients across all services is essential to maintain resilient healthcare systems.

OBJECTIVES: First Nations people report high levels of wellness despite high rates of chronic illness. Our goal was to understand the factors associated with wellness among First Nations adults in Ontario who were considered frail. METHODS: Using the First Nations Regional Health Survey, we created a profile of First Nations adults (aged 45+) who were categorized as "frail" (weighted sample size = 8121). We used multivariate logistic regression to determine associations between wellness (as measured by self-reported physical, emotional, mental, and spiritual balance) and determinants of health. RESULTS: Rates of reported wellness were high among those who were frail, ranging from 56.7% reporting physical balance to 71.6% reporting mental balance. Three key elements were associated with wellness: the availability of resources, individual lifestyle factors, and cultural connection and identity. DISCUSSION: Our findings provide a profile of strength and wellness among older First Nations adults living with frailty.

BACKGROUND: COVID-19 imposed substantial health and economic burdens. Comprehensive population-based estimates of health care costs for COVID-19 are essential for planning and policy evaluation. We estimated publicly funded health care costs in 2 Canadian provinces during the pandemic's first wave. METHODS: In this historical cohort study, we linked patients with their first positive SARS-CoV-2 test result by June 30, 2020, in 2 Canadian provinces (British Columbia and Ontario) to health care administrative databases and matched to negative or untested controls. We stratified patients by highest level of initial care: community, long-term care, hospital (without admission to the intensive care unit [ICU]) and ICU. Mean publicly funded health care costs for patients and controls, mean net (attributable to COVID-19) costs and total costs were estimated from 30 days before to 120 days after the index date, or to July 31, 2020, in 30-day periods for patients still being followed by the start of each period. RESULTS: We identified 2465 matched people with a positive test result for SARS-CoV-2 in BC and 28 893 in Ontario. Mean age was 53.4 (standard deviation [SD] 21.8) years (BC) and 53.7 (SD 22.7) years (Ontario); 55.7% (BC) and 56.1% (Ontario) were female. Net costs in the first 30 days after the index date were $22 010 (95% confidence interval [CI] 19 512 to 24 509) and $15 750 (95% CI 15 354 to 16 147) for patients admitted to hospital, and $65 828 (95% CI 58 535 to 73 122) and $56 088 (95% CI 53 721 to 58 455) for ICU patients in BC and Ontario, respectively. In the community and long-term care settings, net costs were near 0. Total costs for all people, from 30 days before to 30 days after the index date, were $22 128 330 (BC) and $175 778 210 (Ontario). INTERPRETATION: During the first wave, we found that mean costs attributable to COVID-19 were highest for patients with ICU admission and higher in BC than Ontario. Reducing the number of people who acquire COVID-19 and severity of illness are required to mitigate the economic impact of COVID-19.

Protein kinase CK1alpha regulates several fundamental cellular processes including proliferation and differentiation. Up to four forms of this kinase are expressed in vertebrates resulting from alternative splicing of exons; these exons encode either the L-insert located within the catalytic domain or the S-insert located at the C terminus of the protein. Whereas the L-insert is known to target the kinase to the nucleus, the functional significance of nuclear CK1alphaLS has been unclear. Here we demonstrate that selective L-insert-targeted short hairpin small interfering RNA-mediated knockdown of CK1alphaLS in human vascular endothelial cells and vascular smooth muscle cells impairs proliferation and abolishes hydrogen peroxide-stimulated proliferation of vascular smooth muscle cells, with the cells accumulating in G(0)/G(1). In addition, selective knockdown of CK1alphaLS in cultured human arteries inhibits vascular activation, preventing smooth muscle cell proliferation, intimal hyperplasia, and proteoglycan deposition. Knockdown of CK1alphaLS results in the harmonious down-regulation of its target substrate heterogeneous nuclear ribonucleoprotein C and results in the altered expression or alternative splicing of key genes involved in cellular activation including CXCR4, MMP3, CSF2, and SMURF1. Our results indicate that the nuclear form of CK1alpha in humans, CK1alphaLS, plays a critical role in vascular cell proliferation, cellular activation, and hydrogen peroxide-mediated mitogenic signal transduction.

INTRODUCTION: Globally, the ways that Indigenous data are collected, used, stored, shared, and analyzed are advancing through Indigenous data governance movements. However, these discussions do not always include the increasingly sensitive nature of linking Indigenous population health (IPH) data. During the International Population Data Linkage Network Conference in September of 2018, Indigenous people from three countries (Canada, New Zealand, and the United States) gathered and set the tone for discussions around Indigenous-driven IPH data linkage. OBJECTIVES: Centering IPH data linkage and research priorities at the conference led to budding discussions from diverse Indigenous populations to share and build on current IPH data linkage themes. This paper provides a braided summary of those discussions which resulted in the SEEDS principles for use when linking IPH data. METHODS: During the Conference, two sessions and a keynote were Indigenous-led and hosted by international collaborators that focused on regional perspectives on IPH data linkage. A retrospective document analysis of notes, discussions, and artistic contributions gathered from the conference resulted in a summary of shared common approaches to the linkage of IPH data. RESULTS: The SEEDS Principles emerge as collective report that outlines a living and expanding set of guiding principles that: 1) prioritizes Indigenous Peoples' right to Self-determination; 2) makes space for Indigenous Peoples to Exercise sovereignty; 3) adheres to Ethical protocols; 4) acknowledges and respects Data stewardship and governance, and; 5) works to Support reconciliation between Indigenous nations and settler states. CONCLUSION: Each of the elements of SEEDS need to be enacted together to create a positive data linkage environment. When implemented together, the SEEDS Principles can lead to more meaningful research and improved Indigenous data governance. The mindful implementation of SEEDS could lead to better measurements of health progress through linkages that are critical to enhancing health care policy and improving health and wellness outcomes for Indigenous nations.

INTRODUCTION: Despite increasing dementia rates, few culturally informed cognitive assessment tools exist for Indigenous populations. The Canadian Indigenous Cognitive Assessment (CICA) was adapted with First Nations on Manitoulin Island, Canada, and provides a brief, multi-domain cognitive assessment in English and Anishinaabemowin. METHODS: Using community-based participatory research (CBPR) methods, we assessed the CICA for inter-rater and test-retest reliability in 15 individuals. We subsequently evaluated validity and established meaningful CICA cut-off scores in 55 individuals assessed by a geriatrician. RESULTS: The CICA demonstrated strong reliability (intra-class coefficient = 0.95 [0.85,0.98]). The area under the curve (AUC) was 0.98 (0.94, 1.00), and the ideal cut-point to identify likely cases of dementia was a score of less than or equal to 34 with sensitivity of 100% and specificity of 85%. DISCUSSION: When used with older First Nations men and women living in First Nations communities, the CICA offers a culturally safe, reliable, and valid assessment to support dementia case-finding.
RESUMEN
BACKGROUND: Colonization and marginalization have affected the risk for and experience of hepatitis C virus (HCV) infection for First Nations people in Canada. In partnership with the Ontario First Nations HIV/AIDS Education Circle, we estimated the publicly borne health care costs associated with HCV infection among Status First Nations people in Ontario. METHODS: In this retrospective matched cohort study, we used linked health administrative databases to identify Status First Nations people in Ontario who tested positive for HCV antibodies or RNA between 2004 and 2014, and Status First Nations people who had no HCV testing records or only a negative test result (control group, matched 2:1 to case participants). We estimated total and net costs (difference between case and control participants) for 4 phases of care: prediagnosis (6 mo before HCV infection diagnosis), initial (after diagnosis), late (liver disease) and terminal (6 mo before death), until death or Dec. 31, 2017, whichever occurred first. We stratified costs by sex and residence within or outside of First Nations communities. All costs were measured in 2018 Canadian dollars. RESULTS: From 2004 to 2014, 2197 people were diagnosed with HCV infection. The mean net total costs per 30 days of HCV infection were $348 (95% confidence interval [CI] $277 to $427) for the prediagnosis phase, $377 (95% CI $288 to $470) for the initial phase, $1768 (95% CI $1153 to $2427) for the late phase and $893 (95% CI -$1114 to $3149) for the terminal phase. After diagnosis of HCV infection, net costs varied considerably among those who resided within compared to outside of First Nations communities. Net costs were higher for females than for males except in the terminal phase. INTERPRETATION: The costs per 30 days of HCV infection among Status First Nations people in Ontario increased substantially with progression to advanced liver disease and finally to death. These estimates will allow for planning and evaluation of provincial and territorial population-specific hepatitis C control efforts.

BACKGROUND: Hepatitis C virus (HCV) infection causes substantial morbidity and mortality in Canada and is of concern among First Nations communities. In partnership with the Ontario First Nations HIV/AIDS Education Circle, we described trends in HCV testing and epidemiologic features among Status First Nations people in Ontario. METHODS: In this retrospective study, we used health administrative databases for 2006-2014 in Ontario with 3 cohorts of Status First Nations people: those tested for HCV for the first time, those who tested positive for HCV antibodies or RNA, and those with no HCV laboratory or testing records. We examined cohort characteristics, and the annual prevalence and incidence of testing and diagnosis of HCV infection. Outcomes were stratified by region, sex and residence within or outside of First Nations communities. RESULTS: During the study period, 2423 Status First Nations people were diagnosed with HCV infection, 20 481 received their first test, and 135 185 had no test record. The point prevalence of ever having been tested increased from 6.3 (95% confidence interval [CI] 6.2-6.5) per 100 people in 2006 to 16.2 (95% CI 16.0-16.4) per 100 people in 2014. The point prevalence of diagnosed HCV infection increased from 0.9 (95% CI 0.9-1.0) to 2.0 (95% CI 1.9-2.0) per 100 people. The incidence of first test and of diagnosis increased from 12.1 (95% CI 11.5-12.6) to 21.3 (95% CI 20.5-22.1) per 1000 person-years and from 1.3 (95% CI 1.1-1.5) to 2.3 (95% CI 2.1-2.6) per 1000 person-years, respectively. Testing, diagnosis and prevalence of HCV infection were consistently higher among people living outside of versus within First Nations communities, but larger increases over time were observed among those living within First Nations communities. INTERPRETATION: Testing and diagnosis of HCV infection increased from 2006 to 2014 among Status First Nations people in Ontario. Our findings indicate the need for population-level efforts to eliminate hepatitis C in First Nations communities.

This study, the first published overview of aging in a nationally representative sample of First Nations seniors, used data from the First Nations Regional Health Survey Phase 2 (FNRHS 2). It is also the first application of a validated frailty index to describe aging experiences in First Nations communities. Responding to the survey were 11,043 First Nations adults. Of the 1,820 First Nations seniors who responded, 52.7 per cent (95% CI [49.4-56.1]) were not frail. The maintenance of non-frail status in First Nations adults appeared to decrease in each middle-adult age group (from 87.9% in ages 35-44 through to 63.1% in ages 55-64) and to plateau after age 65. The findings are a key step in documenting the experiences of First Nations seniors nationally from a First Nations perspective. They also highlight the key need for supportive health services and chronic disease management at younger ages.
Cette étude est le premier aperçu publié sur le vieillissement utilisant dans un échantillon représentatif au plan national de personnes âgées vivant dans des communautés des Premières Nations, à partir des données générées par la Phase 2 de l'Enquête régionale sur la santé des Premières Nations (ERSPN-2). Il s'agit également de la première application de l'indice de fragilité validé pour décrire les expériences de vieillissement dans les communautés des Premières Nations. Il y avait 11 043 adultes des Premières Nations qui ont répondu à l'ERSPN-2. Sur les 1 820 aînés des Premières Nations qui ont répondu à l'ERSPN-2, 52,7% (IC 95%: 49,4 à 56,1) n'étaient pas fragiles. Le maintien d'un statut non fragile chez les adultes des Premières Nations semble diminuer dans chaque groupe d'adultes d'âge moyen (de 87,9% chez les 35-44 ans à 63,1% chez les 55-64 ans) et se stabiliser en plateau après 65 ans. Les résultats contribueront à documenter l'expérience du vieillissement chez les membres plus âgés des Premières Nations au plan national, du point de vue des Premières Nations. Ils mettent également en évidence les besoins importants en services de soutien en santé et en gestion des maladies chroniques à un jeune âge dans les communautés des Premières Nations.
