Indigenous identity identification in administrative health care data globally: A scoping review.

OBJECTIVE: Both Indigenous and non-Indigenous governments and organizations have increasingly called for improved Indigenous health data in order to improve health equity among Indigenous peoples. This scoping review identifies best practices, potential consequences and barriers for advancing Indigenous health data and Indigenous data sovereignty globally. METHODS: A scoping review was conducted to capture the breadth and nature of the academic and grey literature. We searched academic databases for academic records published between 2000 and 2021. We used Google to conduct a review of the grey literature. We applied Harfield's Aboriginal and Torres Strait Islander Quality Appraisal Tool (QAT) to all original research articles included in the review to assess the quality of health information from an Indigenous perspective. RESULTS: In total, 77 academic articles and 49 grey literature records were included. Much of the academic literature was published in the last 12 years, demonstrating a more recent interest in Indigenous health data. Overall, we identified two ways for Indigenous health data to be retrieved. The first approach is health care organizations asking clients to voluntarily self-identify as Indigenous. The other approach is through data linkage. Both approaches to improving Indigenous health data require awareness of the intergenerational consequences of settler colonialism along with a general mistrust in health care systems among Indigenous peoples. This context also presents special considerations for health care systems that wish to engage with Indigenous communities around the intention, purpose, and uses of the identification of Indigenous status in administrative databases and in health care settings. Partnerships with local Indigenous nations should be developed prior to the systematic collection of Indigenous identifiers in health administrative data. The QAT revealed that many research articles do not include adequate information to describe how Indigenous communities and stakeholders have been involved in this research. CONCLUSION: There is consensus within the academic literature that improving Indigenous health should be of high priority for health care systems globally. To address data disparities, governments and health organizations are encouraged to work in collaboration with local Indigenous nations and stakeholders at every step from conceptualization, data collection, analysis, to ownership. This finding highlights the need for future research to provide transparent explanation of how meaningful Indigenous collaboration is achieved in their research.

Incidence and outcomes of critical illness in indigenous peoples: a systematic review and meta-analysis.

BACKGROUND: Indigenous Peoples experience health inequities and racism across the continuum of health services. We performed a systematic review and meta-analysis of the incidence and outcomes of critical illness among Indigenous Peoples. METHODS: We searched Ovid MEDLINE/PubMed, Ovid EMBASE, Google Scholar, and Cochrane Central Register of Controlled Trials (inception to October 2022). Observational studies, case series of > 100 patients, clinical trial arms, and grey literature reports of Indigenous adults were eligible. We assessed risk of bias using the Newcastle-Ottawa Scale and appraised research quality from an Indigenous perspective using the Aboriginal and Torres Strait Islander Quality Assessment Tool. ICU mortality, ICU length of stay, and invasive mechanical ventilation (IMV) were compared using risk ratios and mean difference (MD) for dichotomous and continuous outcomes, respectively. ICU admission was synthesized descriptively. RESULTS: Fifteen studies (Australia and/or New Zealand [n = 12] and Canada [n = 3]) were included. Risk of bias was low in 10 studies and moderate in 5, and included studies had minimal incorporation of Indigenous perspectives or consultation. There was no difference in ICU mortality between Indigenous and non-Indigenous (RR 1.14, 95%CI 0.98 to 1.34, I2 = 87%). We observed a shorter ICU length of stay among Indigenous (MD - 0.25; 95%CI, - 0.49 to - 0.00; I2 = 95%) and a higher use for IMV among non-Indigenous (RR 1.10; 95%CI, 1.06 to 1.15; I2 = 81%). CONCLUSION: Research on Indigenous Peoples experience with critical care is poorly characterized and has rarely included Indigenous perspectives. ICU mortality between Indigenous and non-Indigenous populations was similar, while there was a shorter ICU length of stay and less mechanical ventilation use among Indigenous patients.

Action, Accountability and Transparency for Indigenous Health Systems Safety.

Anti-Indigenous racism is prevalent in Canada, especially within healthcare systems. Consequences are catastrophic, including deaths of Indigenous patients. Systems change and critical education guided by the Indigenous Peoples and research into how racism operates within healthcare settings are needed. In Alberta, promising initiatives are under way, including a First Nations-led initiative identifying racism and colonialism as key health determinants, novel experiential education, transformative education for senior health leaders and reframing health system measures to reflect Indigenous Peoples' perspectives. The time is now for comprehensive action toward eliminating racism within healthcare systems and fostering Indigenous health systems safety. Indigenous lives depend on it.

Nehiyawak (Cree) women's strategies for aging well: community-based participatory research in Maskwacîs, Alberta, Canada, by the Sohkitehew (Strong Heart) group.

BACKGROUND: The Sohkitehew (Strong Heart) Research Group, which included an Elders Advisory Committee of seven Nehiyawak (Cree) women, set out to bring Maskwacîs community members together to understand Nehiyawak women's experiences of "aging well". The goals of this research were to generate information honouring Indigenous ways of knowing, and gather strengths-based knowledge about aging well, to help Maskwacîs, women maintain wellness as they age. METHODS: We facilitated qualitative Sharing Circles in three different settings in Maskwacîs. Discussions were prompted using the four aspects of the self, guided by Medicine Wheel teachings: Physical, Mental, Emotional, Spiritual. Detailed notes were recorded on flip charts during the discussions of each Sharing Circle. Data were analysed using descriptive content analysis to identify practical strategies for aging well. RESULTS: Thirty-six community members attended one or more Sharing Circle. Strategies included: Physical-keeping active to remain well; Mental-learning new skills to nourish your mind; Emotional-laughing, crying, and being happy; Spiritual-practicing Nehiyawak traditional ways. Participants commented that balancing these four aspects of the self is necessary to achieve wellness. Following the analysis of the Sharing Circle comments, three community feedback sessions were held to discuss the results in the wider community. These strategies were formatted into a draft booklet which incorporated Cree language, and archive photographs of Maskwacîs women and families. CONCLUSIONS: The Nehiyawak Sharing Circles identified practical strategies that help women to remain well as they age. This positive approach to aging could be adopted in other Indigenous and non-Indigenous communities.

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.

Mâmawihitowin (bringing the camps together): Perinatal healthcare provider and staff participation in an Indigenous-led experiential intervention for enhancing culturally informed care-a mixed methods study.

BACKGROUND: In partnership with a Nehiyawak (Plains Cree) community of Maskwacîs,central Alberta (Canada), we implemented an Indigenous-led intervention to provide experiential learning opportunities for perinatal health care providers (HCPs) and staff. Our objective was to capture the impact of participating in cultural safety learning opportunities on perceived self-awareness for HCPs and staff to provide enhanced culturally informed care. METHODS: Perinatal HCPs and staff who work regularly with Indigenous women from our partnering community took part in a series of experiential learning activities designed by a Community Advisory Committee. We used an explanatory sequential mixed methods approach informed by community-based participatory research. We compared Cultural Intelligence Scale (CQS) and Maskwacîs-Specific Cultural Scale (MSCS) scores pre- and post-intervention using non-parametrical statistical analysis (Wilcoxon signed rank test). Post-intervention, we conducted a qualitative description study using semi-structured interviews. Qualitative data was analyzed using thematic analysis. RESULTS: A total of 17 participants completed pre- and post-intervention questionnaires. Responses indicated a shift in perceived cultural and community knowledge and comfort levels, with positive gains in overall mean scores for both the CQS (p = 0.01) and MSCS (p = 0.01). Nine participants completed qualitative interviews. Overall, participants felt better equipped to provide more culturally informed care to their patients post-intervention. CONCLUSION: An Indigenous-led experiential learning intervention was effective in enhancing overall perceived cultural awareness and preparedness to provide culturally informed care for perinatal HCPs and staff. This study provides evidence for fostering relationships between Indigenous communities and health systems toward enhanced perinatal care.

Commentary: Developing Relationships through Trust in Indigenous Health Research.

Developing strong relationships between researchers and Indigenous partners and communities is crucial for mutually beneficial and appropriate Indigenous health research. However, explanations on the need for strong relationships and how they may be achieved are not often found within the research literature. Given the history of mistrust, exploitation and even unethical research practices with Indigenous populations, collaborative research partnerships necessitate good relationships. For our long-standing community-based participatory research partnership, trust in our relationships has been foundational. Several key elements are central to developing this trust, including coming together in ceremony, practising humility and becoming personally and emotionally invested in each other's lives. We also prioritize time, effort and flexibility to actively work on our relationships. To make effective and beneficial change within Indigenous health research compels reframing western perspectives and overcoming long-standing institutional barriers, such that enduring and trusting relationships are the focus and not a means to an end.

Healthy food prescription incentive programme for adults with type 2 diabetes who are experiencing food insecurity: protocol for a randomised controlled trial, modelling and implementation studies.

INTRODUCTION: The high cost of many healthy foods poses a challenge to maintaining optimal blood glucose levels for adults with type 2 diabetes mellitus who are experiencing food insecurity, leading to diabetes complications and excess acute care usage and costs. Healthy food prescription programmes may reduce food insecurity and support patients to improve their diet quality, prevent diabetes complications and avoid acute care use. We will use a type 2 hybrid-effectiveness design to examine the reach, effectiveness, adoption, implementation and maintenance (RE-AIM) of a healthy food prescription incentive programme for adults experiencing food insecurity and persistent hyperglycaemia. A randomised controlled trial (RCT) will investigate programme effectiveness via impact on glycosylated haemoglobin (primary outcome), food insecurity, diet quality and other clinical and patient-reported outcomes. A modelling study will estimate longer-term programme effectiveness in reducing diabetes-related complications, resource use and costs. An implementation study will examine all RE-AIM domains to understand determinants of effective implementation and reasons behind programme successes and failures. METHODS AND ANALYSIS: 594 adults who are experiencing food insecurity and persistent hyperglycaemia will be randomised to a healthy food prescription incentive (n=297) or a healthy food prescription comparison group (n=297). Both groups will receive a healthy food prescription. The incentive group will additionally receive a weekly incentive (CDN$10.50/household member) to purchase healthy foods in supermarkets for 6 months. Outcomes will be assessed at baseline and follow-up (6 months) in the RCT and analysed using mixed-effects regression. Longer-term outcomes will be modelled using the UK Prospective Diabetes Study outcomes simulation model-2. Implementation processes and outcomes will be continuously measured via quantitative and qualitative data. ETHICS AND DISSEMINATION: Ethical approval was obtained from the University of Calgary and the University of Alberta. Findings will be disseminated through reports, lay summaries, policy briefs, academic publications and conference presentations. TRIAL REGISTRATION NUMBER: NCT04725630. PROTOCOL VERSION: Version 1.1; February 2022.

Wîcohkamakew ("S/he Helps Someone"): A Qualitative Description of Experiences with a Community-derived Elders Mentoring Program for Indigenous Parents-to-be.

BACKGROUND: Responding to concerns about perinatal health risks and adverse outcomes, we established a community-based participatory research (CBPR) partnership between a Nêhiyawi (Cree) community and university-based researchers. We designed and implemented a community-derived Elders Mentoring Program (EMP) to provide additional support for pregnant women and their partners. Our objective was to understand the collective experiences of those involved in the Program. METHODS: We conducted a qualitative description with the principles of CBPR as an overarching framework. We carried out 14 qualitative interviews with parents, perinatal clinic staff, and mentor Elders involved in the Program. We also used detailed notes from Community Advisory Committee (CAC) meetings as data. All qualitative data were analyzed with content analysis. RESULTS: The Program helped pregnant women and their partners by fostering enhanced and multi-generational support networks. It also improved cultural security within the clinical environment and learning among health care staff. A sense of intergenerational fulfillment and enjoyment among those involved was common and was underpinned by genuine, collaborative relationships. CONCLUSIONS: A community-derived prenatal EMP, designed in partnership with those who have intimate knowledge of the community, is a major step toward ensuring multi-generational and culturally secure care in pregnancy for women and families.

Menopause experience in First Nations women and initiatives for menopause symptom awareness; a community-based participatory research approach.

BACKGROUND: Little research has been conducted about menopause in First Nations women. In response to the wishes of Cree women living in Maskwacis, Alberta, to start a dialogue on menopause, we undertook community-based participatory research (CBPR) to explore menopause experience and raise awareness of menopause symptoms in the community. METHODS: The research adhered to the principles of Ownership, Control, Access and Possession (OCAP™) and was guided by the interest of the participating women. Local women (target age 40-65 years) were invited to participate in workshops using word-of-mouth and community posters in health centers. Five research workshops were held in community settings, attended by experienced women's health researchers and consenting women. The participants guided the informal discussions. They also completed questionnaires which included menopause-related quality of life. The researchers used extensive hand-written field notes to record data; qualitative content analysis was applied to identify themes. Simple descriptive analysis was used for the questionnaire results. The findings were discussed at a community feedback session and laid the basis for further knowledge translation initiatives. RESULTS: The five workshops included a total of 37, mostly post-menopausal women with 6-11 women/workshop. The main discussion themes were: "experiences of menopause symptoms" including their impact on quality of life; "menopause knowledge prior to their own experience" with most women feeling that they had insufficient information before menopause; "menopause symptom management" which mainly included practical strategies; "impact of menopause on family members" which was of prime concern with uncontrollable mood changes affecting the whole family and sometimes causing matrimonial disharmony. Questionnaire responses corroborated the workshop discussions. Knowledge translation of the research findings produced two information pamphlets specifically for the Maskwacis community: one for husband/partner, the other for women and family members. These pamphlets have been distributed in all areas of the community. CONCLUSION: This CBPR project addressed a topic identified by the community as being important. Community members developed informative pamphlets in response to the women's concern of lack of understanding for menopause symptoms among families. This simple solution has been widely accepted by community members, opening the possibility of wider discussion about menopause.

Strategies for Promoting Healthy Nutrition and Physical Activity Among Young Children: Priorities of Two Indigenous Communities in Canada.

BACKGROUND: Indigenous people in Canada carry a disproportionate burden of obesity and obesity-related diseases compared with non-Indigenous Canadians, which could be related to intergenerational trauma exposures. Implementing effective health promotion strategies to improve nutrition and physical activity behaviors during early childhood could be a strategy to mitigate the burden of intergenerational trauma exposures that have the potential to impact the trajectory to obesity and related complications throughout the lifecycle. OBJECTIVES: The aim of this study was to support 2 Indigenous communities in identifying priorities and strategies for promoting healthy nutrition and physical activity for young children. METHODS: Using a formative approach, we conducted a 2-phase study that started with 2 community engagement workshops (n = 37 participants), followed by a qualitative descriptive study. In this latter study, in-depth interviews were conducted with a purposeful sample of 23 community parents, health care providers, and traditional knowledge holders. Data from both study phases were analyzed and synthesized using conventional content analysis. RESULTS: To promote healthy nutrition and physical activity among young children living in Indigenous communities, it was identified that the primary pathway to health and well-being must prioritize the integration of knowledge about Indigenous ways of life including traditional Indigenous foods and physical activities. Participants also identified individual/family and community/contextual factors that ultimately influence the nutrition and physical activity of children in their communities. CONCLUSIONS: Informed by this formative study conducted to better understand community members' strategies for healthy eating and physical activity for young children, we argue for the continued recognition of the unique Indigenous context, incorporating the history of inequity and injustice and looking toward Indigenous-led interventions that incorporate this history and ways of life as solutions in the future.

Explaining the variability in cardiovascular risk factors among First Nations communities in Canada: a population-based study.

BACKGROUND: Historical, colonial, and racist policies continue to influence the health of Indigenous people, and they continue to have higher rates of chronic diseases and reduced life expectancy compared with non-Indigenous people. We determined factors accounting for variations in cardiovascular risk factors among First Nations communities in Canada. METHODS: Men and women (n=1302) aged 18 years or older from eight First Nations communities participated in a population-based study. Questionnaires, physical measures, blood samples, MRI of preclinical vascular disease, and community audits were collected. In this cross-sectional analysis, the main outcome was the INTERHEART risk score, a measure of cardiovascular risk factor burden. A multivariable model was developed to explain the variations in INTERHEART risk score among communities. The secondary outcome was MRI-detected carotid wall volume, a measure of subclinical atherosclerosis. FINDINGS: The mean INTERHEART risk score of all communities was 17·2 (SE 0·2), and more than 85% of individuals had a risk score in the moderate to high risk range. Subclinical atherosclerosis increased significantly across risk score categories (p<0·0001). Socioeconomic advantage (-1·4 score, 95% CI -2·5 to -0·3; p=0·01), trust between neighbours (-0·7, -1·2 to -0·3; p=0·003), higher education level (-1·9, -2·9 to -0·8, p<0·001), and higher social support (-1·1, -2·0 to -0·2; p=0·02) were independently associated with a lower INTERHEART risk score; difficulty accessing routine health care (2·2, 0·3 to 4·1, p=0·02), taking prescription medication (3·5, 2·8 to 4·3; p<0·001), and inability to afford prescription medications (1·5, 0·5 to 2·6; p=0·003) were associated with a higher INTERHEART risk score. Collectively, these factors explained 28% variation in the cardiac risk score among communities. Communities with higher socioeconomic advantage and greater trust, and individuals with higher education and social support, had a lower INTERHEART risk score. Communities with difficulty accessing health care, and individuals taking or unable to afford prescription medications, had a higher INTERHEART risk score. INTERPRETATION: Cardiac risk factors are lower in communities with high socioeconomic advantage, greater trust, social support and educational opportunities, and higher where it is difficult to access health care or afford prescription medications. Strategies to optimise the protective factors and reduce barriers to health care in First Nations communities might contribute to improved health and wellbeing.

Peyakohewamak-Needs of Involved Nehiyaw (Cree) Fathers Supporting Their Partners During Pregnancy: Findings From the ENRICH Study.

We sought to understand the needs of involved Nehiyaw (Cree) fathers who supported their partners during pregnancy. We used qualitative description and a community-based participatory research approach. We carried out in-depth semi-structured interviews with six Nehiyaw fathers. Four also participated in photovoice and follow-up interviews. All data were content analyzed qualitatively. Fathers felt they had to support their partners and overcome challenges resulting from intergenerational colonial impacts (residential schools particularly) by reclaiming their roles and acknowledging the pregnancy as a positive change. Providing support was possible through their own strong support system stemming from family, faith, culture, and a stable upbringing with positive male role models and intact Nehiyaw kinships. Perinatal programming did little to include fathers. Attempts to improve perinatal care and outcomes should allow more inclusion of and support for Indigenous fathers through genuinely incorporating into care traditional culture and Elders, families, flexibility, cultural understanding, and reconciliation.

Canadian Alliance for Healthy Hearts and Minds: First Nations Cohort Study Rationale and Design.

BACKGROUND: This is the first national indigenous cohort study in which a common, in-depth protocol with a common set of objectives has been adopted by several indigenous communities across Canada. OBJECTIVES: The overarching objective of the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort is to investigate how the community-level environment is associated with individual health behaviors and the presence and progression of chronic disease risk factors and chronic diseases such as cardiovascular disease (CVD) and cancer. METHODS: CAHHM aims to recruit approximately 2,000 First Nations indigenous individuals from up to nine communities across Canada and have participants complete questionnaires, blood collection, physical measurements, cognitive assessments, and magnetic resonance imaging (MRI). RESULTS: Through individual- and community-level data collection, we will develop an understanding of the specific role of the socioenvironmental, biological, and contextual factors have on the development of chronic disease risk factors and chronic diseases. CONCLUSIONS: Information collected in the indigenous cohort will be used to assist communities to develop local management strategies for chronic disease, and can be used collectively to understand the contextual, environmental, socioeconomic, and biological determinants of differences in health status in harmony with First Nations beliefs and reality.

Kikiskawâwasow - prenatal healthcare provider perceptions of effective care for First Nations women: an ethnographic community-based participatory research study.

BACKGROUND: Pregnant Indigenous women suffer a disproportionate burden of risk and adverse outcomes relative to non-Indigenous women. Although there has been a call for improved prenatal care, examples are scarce. Therefore, we explored the characteristics of effective care with First Nations women from the perspective of prenatal healthcare providers (HCPs). METHODS: We conducted an ethnographic community-based participatory research study in collaboration with a large Cree First Nations community in Alberta, Canada. We carried out semi-structured interviews with 12 prenatal healthcare providers (HCPs) that were recorded, transcribed, and subjected to qualitative content analysis. RESULTS: According to the participants, relationships and trust, cultural understanding, and context-specific care were key features of effective prenatal care and challenge the typical healthcare model. HCPs that are able to foster sincere, non-judgmental, and enjoyable interactions with patients may be more effective in treating pregnant First Nations women, and better able to express empathy and understanding. Ongoing HCP cultural understanding specific to the community served is crucial to trusting relationships, and arises from real experiences and learning from patients over and above relying only on formal cultural sensitivity training. Consequently, HCPs report being better able to adapt a more flexible, all-inclusive, and accessible approach that meets specific needs of patients. CONCLUSIONS: Aligned with the recommendations of the Truth and Reconciliation Commission of Canada, improving prenatal care for First Nations women needs to allow for genuine relationship building with patients, with enhanced and authentic cultural understanding by HCPs, and care approaches tailored to women's needs, culture, and context.

High Frequency of Pre-Existing Type 2 Diabetes in a Series of Pregnant Women Referred for "Gestational Diabetes" in a Large Canadian Indigenous Community.

We examined the referral processes and true diagnostic classifications for diabetes complicating pregnancy in a series of 62 pregnant women consecutively referred to a diabetes education and treatment centre in a large Indigenous community in Alberta, Canada. The referrals were made over a 5-year period (2010 to 2015). The main findings of this analysis were the high frequency (38.7%) of pre-existing type 2 diabetes and previously undiagnosed or unrecognized overt diabetes and the deficiencies in early testing and recognition.

Longitudinal Rates and Risk Factors for Adverse Birth Weight Among First Nations Pregnancies in Alberta.

OBJECTIVE: We wished to identify the prevalence, longitudinal trends, and associated risk factors for various birth weight categories by First Nations ethnicity in the province of Alberta. METHODS: We performed a retrospective analysis of administrative data for the years 2000 to 2009 inclusive. Age-adjusted prevalence trends for high birth weight (HBW; > 4000g), very HBW (> 4500g), low birth weight (LBW; < 2500g), and very LBW (< 1500g) were compared via average annual percent change analyses. Logistic regression analysis was used to determine risk factors. RESULTS: First Nations ethnicity was a significant independent predictor of HBW (OR 1.82 [95% CI 1.75, 1.89]), very HBW (OR 2.35 [95% CI 2.18, 2.52]), and very LBW (OR 1.35 [95% CI 1.23, 1.48]), but not of LBW (OR 0.98 [95% CI 0.93, 1.03]). However, HBW prevalence decreased and other birth weight categories remained stable over time in First Nations populations. Gestational diabetes and maternal weight ≥ 91 kg were potentially manageable risk factors for HBW. Potentially manageable risk factors for LBW included pre-gestational renal disease, hypertension, and maternal weight ≤ 45 kg, as well as smoking, illicit drug dependence, and alcohol consumption. CONCLUSION: Although HBW, very HBW, and very LBW remain more common in Alberta First Nations populations than in the general population, their prevalence is not increasing.

A retrospective analysis of stillbirth epidemiology and risk factors among First Nations and non-First Nations pregnancies in Alberta from 2000 to 2009.

OBJECTIVE: Using a large administrative dataset we examined stillbirth epidemiology in First Nations and non-First Nations pregnancies in Alberta, focusing on previously unexplored longitudinal trends. METHODS: We undertook a retrospective analysis of de-identified data from 426 945 delivery records for the years 2000 to 2009. Age-adjusted prevalence of antepartum and intrapartum stillbirth were calculated and compared by ethnicity, as were longitudinal changes via average annual percent change analyses. Risk factors were explored via multivariable logistic regression analysis. RESULTS: Overall age-adjusted prevalence of antepartum and intrapartum stillbirth was significantly higher (P < 0.001) in First Nations pregnancies than in non-First Nations pregnancies, and prevalence remained stable over time in both groups. Pre-existing diabetes was a strong predictor of stillbirth. CONCLUSION: Stillbirth prevalence remains higher in First Nations pregnancies than in non-First Nations. Improved awareness of pre-existing diabetes and effective interventions are needed in First Nations women to decrease stillbirth risk.

Objectif : En utilisant un important ensemble de données administratives, nous nous sommes penchés sur l'épidémiologie de la mortinaissance dans le cas des grossesses chez des femmes issues ou non des Premières Nations en Alberta; nous nous sommes alors centrés sur des tendances longitudinales qui n'avaient pas déjà été explorées. Méthodes : Nous avons mené une analyse rétrospective de données anonymisées issues de 426 945 dossiers d'accouchement pour la période 2000-2009. La prévalence (corrigée en fonction de l'âge) de la mortinaissance antepartum et intrapartum a été calculée et comparée en fonction de l'origine ethnique, tout comme les modifications longitudinales l'ont été par l'intermédiaire d'analyses des modifications annuelles moyennes en pourcentage. Les facteurs de risque ont été explorés par analyse de régression logistique multivariée. Résultats : La prévalence (corrigée en fonction de l'âge) globale de la mortinaissance antepartum et intrapartum était considérablement plus élevée (P < 0,001) dans le cadre des grossesses chez des femmes issues des Premières Nations que dans celui des grossesses chez des femmes n'étant pas issues des Premières Nations; cette prévalence est demeurée stable avec le temps au sein des deux groupes. Le diabète préexistant constituait un important facteur prédictif pour ce qui est de la mortinaissance. Conclusion : La prévalence de la mortinaissance demeure plus élevée chez les femmes des Premières Nations. Pour en venir à abaisser le risque de mortinaissance chez celles-ci, nous devons nous efforcer d'améliorer la détection du diabète préexistant et de mettre en œuvre des interventions efficaces.
