Exploring uptake of HIV/STI knowledge and safer sex-efficacy in an arts-based sexual health workshop among Northern and Indigenous adolescents in the Northwest Territories, Canada.

ABSTRACTLimited research has evaluated sexual health promotion projects with adolescents living in Arctic regions. The study objective was to examine changes in STI knowledge and safer sex efficacy among youth in the Northwest Territories (NWT), Canada who participated in arts-based sexual health workshops. We used a pre/post-test design with a convenience sample of students aged 13-18 years recruited from 17 NWT communities. We conducted summary statistics and comparisons between pre and post-test scores using paired t-tests. Among participants (n = 610), we found statistically significant increases in STI knowledge overall (mean difference = 3.9; p < 0.001) and across gender and age stratifications. There were statistically significant increases in safer sex efficacy overall (mean difference = 0.9, p < 0.001), across genders, and among participants: aged <15 years, in rural communities, reporting food insecurity, reporting dating violence, and Indigenous youth. No statistically significant differences in safer sex efficacy were observed among participants who were aged ≥15, sexually active, reporting consistent condom use, and using drugs/alcohol. Findings signal the promise of youth-targeted, arts-based sexual health workshops for improving STI knowledge and safer sex efficacy among adolescents in the NWT. Further research can explore how safer sex efficacy may be shaped by age, substance use, and sexual experience to inform tailored interventions.

Characterizing observed surface wind speed in the Hudson Bay and Labrador regions of Canada from an aviation perspective.

Wind speed analysis is important for informing airport operation and safety. Many communities in the Hudson Bay and Labrador regions (Canada) are remote communities that rely heavily on aircraft for passenger and freight movement. Historical trends in average daily wind speed and maximum daily wind speed from 1971 to 2010 were examined to identify patterns of change and determine how these changes may influence aviation in six northern communities across Hudson Bay and Labrador in Canada. Significant increases in average wind speed and maximum wind speed were found for some of the months and seasons of the year for the Hudson Bay region, along with a significant decrease in those variables for the Labrador communities. Average wind speeds at multiple locations are approaching the threshold (18.5 km/h or 10 knots) when take-off and landing would be restricted to one direction. The results of this study agree with previous research that examined historical patterns for wind speed in these regions but calls into question climate change impact assessments that suggest wind speeds will continue to increase under future climatic conditions for this study area. Future research is needed to further analyse shifts in prevailing wind directions and changes in the frequency of extreme wind conditions, to better understand the potential impacts of projected climate change on this climatic variable and the implications these changes may have on applied sectors, such as aviation.

Planning for social and community-engaged closure: A comparison of mine closure plans from Canada's territorial and provincial North.

The inevitable closure and remediation phase of a mine's lifecycle routinely causes negative socio-economic and environmental impacts for nearby communities. While closure planning is meant to ensure post-closure human and environmental safety, it tends to favour short-term technical fixes over longer-term socio-economic, cultural, and ecological considerations. For mines operating on Indigenous territories, where communities have complex and nuanced connections to land and varying levels of jurisdiction, these issues are further exacerbated by the exclusion of Indigenous voices from planning and decision-making. This research employed a qualitative document analysis of ten mine closure plans for mines in Northern Canada that are still operational to understand how the industry is actively planning for the closure and remediation of their sites. In particular, this work asks whether or not mine companies are incorporating Indigenous Knowledge into their mine closure plans, and how they are addressing the complex socio-economic aspects of closure. This analysis showed that mine closure plans across Northern Canada inconsistently apply Indigenous Knowledge and expertise, and the methods used for community consultation in mine closure planning are left vague. While differences in policy between Northern territories and regions account for some of these inconsistencies, a company's willingness to work beyond baseline requirements imposed by governments is also an important factor. Additionally, these closure plans further demonstrate that the industry prioritizes technical aspects of mine closure over the social, cultural, economic, and ecological. For mine closure to be successful in a Northern context it must incorporate community expertise, emerge from the values and priorities of the Indigenous peoples whose lands mines are operating on, and account for a wider scope of social, economic, and cultural impacts.

Locating the Boundaries of the Nuclear North: Arctic Biology, Contaminated Caribou, and the Problem of the Threshold.

This essay is a historical-geographical account of how scientists and public health officials conceptualized and assessed northern radioactive exposures in the late 1950s and 1960s. The detection of radionuclides in caribou bodies in northern Canada both demonstrated the global reach of nuclear fallout and revealed the unevenness of toxic relations and radioactive exposures. Following the documentation of the lichen-caribou-human pathway of exposure, Canadian public health officials became increasingly concerned about the possibility of heightened radioactive exposures among Indigenous northerners. Between 1963 and 1969, scientists and officials with Canada's Radiation Protection Division (RPD) coordinated an interdepartmental monitoring program through which they sought to determine whether the consumption of contaminated caribou meat had caused radioactive exposure levels in northern communities to exceed the officially recognized "safe limits." In 1969, the northern monitoring program was suspended after officials determined that radionuclide body burdens had not exceeded the threshold for radioactive exposures. While the RPD emphasized its development of a technoscientific approach to measuring radioactive body burdens, the legitimacy of the monitoring program was linked directly to interdepartmental relations within Canada's colonial northern administration. I situate the northern monitoring program within broader shifts in public health approaches to radiation protection and use Gabrielle Hecht's concept of nuclearity to demonstrate how RPD officials employed the logic of the threshold in their assessment of radioactive exposures.

Patient transportation in Canada's northern territories: patterns, costs and providers' perspectives.

INTRODUCTION: Canada's northern territories are characterized by small, scattered populations separated by long distances. A major challenge to healthcare delivery is the reliance on costly patient transportation, especially emergency air evacuations (medevacs). The purpose of this study was to describe the patterns, costs and providers' perspectives on patient transportation, and identify potential factors associated with utilization and performance. METHODS: Secondary analyses of medical travel databases and an online survey of nurses in the communities and physicians in regional centers were undertaken. RESULTS: The proportion of the population living within 100 km of a hospital was 83% in Yukon, 63% in Northwest Territories (NWT) and 21% in Nunavut. In Nunavut and NWT, road access to a hospital was limited to residents of the cities where the hospitals were located, with the rest relying exclusively on air travel. Medevac rates varied among the three territories: 0.9 trips/1000 residents/year in Yukon, 32/1000 in NWT and 53/1000 in Nunavut. In Yukon, all communities except one are road-accessible whereas in Nunavut no communities are connected by roads. The relative absence of roads is a major reason why the patient transportation costs are high in Nunavut and NWT. The rate of medevacs originating from the remote, air-accessible-only communities varied greatly, which cannot be explained by the air distance from the nearest hospital, population size or frequency of health center visits. Medical travel accounts for 5% of the health expenditures in NWT and 20% in Nunavut. A medevac on average costs $218 per person per year in NWT and $700 in Nunavut. The providers survey detected only 66% or less in support of statements that nurses in the communities received timely access to clinical advice, whereas only 50% of physicians agreed with statements that the clinical information provided by the nurses was clear. CONCLUSION: Patient transportation, especially emergency air evacuations, is an essential but costly component of the healthcare system serving Canada's north. It is the 'glue' that binds an extensive network of facilities staffed by different categories of health professionals. While system design is largely dictated by geography, addressing human factors such as interprofessional communication is important for improving the system's effectiveness. This study is primarily descriptive and it points to additional areas for improved understanding of the performance of the system.

"Everything Possible Is Being Done": Labour, Mobility, and the Organization of Health Services in Mid-20th Century Newfoundland.

This article is the Presidential Address to the 2018 meeting of the Canadian Society for the History of Medicine at the University of Regina. It examines the organization of the nursing service in Newfoundland during the 1950s and 1960s, as well as the recruitment and retention of nurses in cottage hospitals and nursing stations in outport communities. A number of interconnected strategies were used by the Newfoundland government to staff the nursing service, including recruiting internationally educated nurses, adjusting expectations with respect to registration standards, and using both trained and untrained workers to support nurses' labour. Although this article is intended more as a reconnaissance suggesting the possibilities of such research, it does analyze the interconnected issues of geography, funding and pay, the nursing shortage, and the renegotiation of nursing labour that characterized this period. Furthermore, although this is a case study of Newfoundland and Labrador, it is worth considering how, or whether, the linked strategies used in the province were transferable to other communities across rural, remote, or northern Canada.

The impacts of the Nutrition North Canada program on the accessibility and affordability of perishable, nutritious foods among eligible communities: a scoping review.

The Nutrition North Canada (NNC) program, introduced in April 2011 is a federal strategy to improve access to perishable, nutritious foods for remote and isolated communities in northern Canada by subsidising retailers to provide price reductions at the point of purchase. As of March 2023, 123 communities are eligible for the program. To evaluate existing evidence and research on the NNC program to inform policy decisions to improve the effectiveness of NNC. A scoping review of peer-reviewed articles was conducted in ten databases along with a supplemental grey literature search of government and non-government reports published between 2011 and 2022. The search yielded 172 publications for screening, of which 42 were included in the analysis. Narrative thematic evidence synthesis yielded 104 critiques and 341 recommendations of the NNC program across eight themes. The most-identified recommendations focus on transparency, communication, and support for harvesting, hunting, and community food initiatives. This review highlights recommendations informed by the literature to address critiques of the NNC program to improve food security, increase access to perishable and non-perishable items, and support community-based food initiatives among eligible communities. The review also identifies priority areas for future policy directions such as additional support for education initiatives, communication and transparency amidst program changes, and food price regulations.

The Yukon's experience with COVID-19: Travel restrictions, variants and spread among the unvaccinated.

The Yukon's experience with coronavirus disease 2019 (COVID-19) has been an interesting one; the territory successfully implemented travel restrictions to limit importing the virus and rolled out vaccines quickly compared to most Canadian jurisdictions. However, the Yukon's first wave of COVID-19 in June and July 2021 overwhelmed the healthcare system due to widespread transmission in unvaccinated children, youth and adults, despite high vaccination uptake overall and mandatory masking. This experience highlights the importance of continued support for public vaccination programs, widespread vaccine uptake in paediatric populations, and the judicious relaxation of non-pharmaceutical interventions in all Canadian jurisdictions as they reopen while more contagious variants emerge.

Ecology of Arctic rabies: 60 years of disease surveillance in the warming climate of northern Canada.

Rabies occurs throughout the Arctic, representing an ongoing public health concern for residents of northern communities. The Arctic fox (Vulpes lagopus) is the main reservoir of the Arctic rabies virus variant, yet little is known about the epidemiology of Arctic rabies, such as the ecological mechanisms driving where and when epizootics in fox populations occur. In this study, we provide the first portrait of the spatio-temporal spread of rabies across northern Canada. We also explore the impact of seasonal and multiannual dynamics in Arctic fox populations and climatic factors on rabies transmission dynamics. We analysed data on rabies cases collected through passive surveillance systems in the Yukon, Northwest Territories, Nunavut, Nunavik and Labrador from 1953 to 2014. In addition, we analysed a large and unique database of trapped foxes tested for rabies in the Northwest Territories and Nunavut from 1974 to 1984 as part of active surveillance studies. Rabies cases occurred in all Arctic regions of Canada and were relatively synchronous among foxes and dogs (Canis familiaris). This study highlights the spread of Arctic rabies virus variant across northern Canada, with contrasting rabies dynamics between different yet connected areas. Population fluctuations of Arctic fox populations could drive rabies transmission dynamics in a complex way across northern Canada. Furthermore, this study suggests different impacts of climate and sea ice cover on the onset of rabies epizootics in northern Canada. These results lay the groundwork for the development of epidemiological models to better predict the spatio-temporal dynamics of rabies occurrence in both wild and domestic carnivores, leading to better estimates of human exposure and transmission risk.

Preliminary clinical algorithm to optimise remote delivery of paediatric concussion care in Canada's North.

Concussion is a form of traumatic brain injury that affects thousands of children and adolescents across Canada annually. With timely access to comprehensive medical care, the majority of patients with acute concussion will recover within 1-4 weeks. Those who develop persistent post-concussion symptoms often benefit from early recognition and referral to multi-disciplinary concussion clinics that have the personnel and resources to meet their complex needs. Youth who live in remote and isolated communities within Canada's North, a significant proportion of whom are Indigenous, face unique barriers and obstacles to accessing primary and specialised concussion care. Although telemedicine has recently emerged as a tool that can help address these gaps in care, there are presently no clinical guidelines or tools available to assist multi-disciplinary concussion clinics in providing remote concussion care to these medically underserved patients. Here we incorporate literature from a scoping review and our early institutional experience to present an evidence-informed preliminary clinical algorithm and resources to help guide and optimise remote paediatric concussion care delivery in Canada's North. We also discuss how innovative technologies and partnerships can be leveraged to enhance the delivery of safe, equitable, cost-effective and culturally appropriate care to these communities.

Protura in Arctic Regions, with Description of Mastodonentomon n. gen. (Acerentomidae, Nipponentominae) and a Key to Known Arctic Taxa.

Protura are widespread, but their presence in the Arctic was first noted only ca. 70 years ago and is still little acknowledged. This work compiles taxonomic information on proturans in the Arctic regions and adds unpublished data from Northern Siberia. Currently, this fauna is represented by 23 species in two orders and 14 genera. The large cosmopolitan genus Eosentomon is represented by only four species, whereas Acerentomidae is much more diverse, with 19 species in 13 genera (eight Nipponentominae, five Acerentominae). Most of the Arctic species possess a larger number of setae than species living in temperate regions. Based on several unique characters, a new genus, Mastodonentomon, is erected for Nipponentomon macleani, and the species is re-described with the original description supplemented with new characters, including head chaetotaxy, seta length, and porotaxy. Proturan occurrence in the Arctic is limited to Beringia, but the majority of species have restricted distributions and none have been found in both the American Arctic and Siberia. This implies relict origins and high levels of proturan endemism in the Arctic. This emerging view on biogeographical history is, however, hampered by the limited extent of available data, which highlights the need for considerably greater survey efforts. A key to Arctic proturans is provided to facilitate further studies.

Opportunities for improving patient experiences among medical travellers from Canada's far north: a mixed-methods study.

OBJECTIVES: This paper explores patient experiences and identifies barriers and opportunities for improving access to healthcare for patients from the Canadian north who travel to receive medical care in a Southern province. DESIGN: A mixed-methods, cross-sectional study involved one-on-one interviews, focus group discussions and key informant interviews. PARTICIPANTS: 52 one-on-one interviews with Northwest Territories (NWT) patients and patient escorts and two focus group discussions (n=10). Fourteen key informant interviews were conducted with health workers, programme managers and staff of community organisations providing services for out-of-province patients. A Community Advisory Board guided the development of the questionnaires and interpretation of results. RESULTS: Respondents were satisfied with the care received overall, but described unnecessary burdens and bureaucratic challenges throughout the travel process. Themes relating to access to healthcare included: plans and logistics for travel; level of communication between services; clarity around jurisdiction and responsibility for care; indirect costs of travel and direct costs of uninsured services; and having a patient escort or advocate available to assist with appointments and navigate the system. Three themes related to healthcare experiences included: cultural awareness, respect and caring, and medical translation. Respondents provided suggestions to improve access to care. CONCLUSIONS: Patients from NWT need more information and support before and during travel. Ensuring that medical travellers and escorts are prepared before departing, that healthcare providers engage in culturally appropriate communication and connecting travellers to support services on arrival have the potential to improve medical travel experiences.

The north is not all the same: comparing health system performance in 18 northern regions of Canada.

We investigated the availability of health system performance indicator data in Canada's 18 northern regions and the feasibility of using the performance framework developed by the Canadian Institute for Health Information [CIHI]. We examined the variation in 24 indicators across regions and factors that might explain such variation. The 18 regions vary in population size and various measures of socioeconomic status, health-care delivery, and health status. The worst performing health systems generally include Nunavut and the northern regions of Québec, Manitoba and Saskatchewan where indigenous people constitute the overwhelming majority of the population, ranging from 70% to 90%, and where they also fare worst in terms of adverse social determinants. All northern regions perform worse than Canada nationally in hospitalisations for ambulatory care sensitive conditions and potentially avoidable mortality. Population size, socioeconomic status, degree of urbanisation and proportion of Aboriginal people in the population are all associated with performance. The North is far from homogenous. Inter-regional variation demands further investigation. The more intermediate pathways, especially between health system inputs, outputs and outcomes, are largely unexplored. Improvement of health system performance for northern and remote regions will require the engagement of indigenous leadership, communities and patient representatives.

Far-Reaching Dispersal of Borrelia burgdorferi Sensu Lato-Infected Blacklegged Ticks by Migratory Songbirds in Canada.

Lyme disease has been documented in northern areas of Canada, but the source of the etiological bacterium, Borrelia burgdorferi sensu lato (Bbsl) has been in doubt. We collected 87 ticks from 44 songbirds during 2017, and 24 (39%) of 62 nymphs of the blacklegged tick, Ixodes scapularis, were positive for Bbsl. We provide the first report of Bbsl-infected, songbird-transported I. scapularis in Cape Breton, Nova Scotia; Newfoundland and Labrador; north-central Manitoba, and Alberta. Notably, we report the northernmost account of Bbsl-infected ticks parasitizing a bird in Canada. DNA extraction, PCR amplification, and DNA sequencing reveal that these Bbsl amplicons belong to Borrelia burgdorferi sensu stricto (Bbss), which is pathogenic to humans. Based on our findings, health-care providers should be aware that migratory songbirds widely disperse B. burgdorferi-infected I. scapularis in Canada's North, and local residents do not have to visit an endemic area to contract Lyme disease.

Retail food environments, shopping experiences, First Nations and the provincial Norths. / Environnement alimentaire de la vente au détail et expériences de magasinage dans les collectivités des Premières nations du nord des provinces.

INTRODUCTION: This paper looks at the market food environments of First Nations communities located in the provincial Norths by examining the potential retail competition faced by the North West Company (NWC) and by reporting on the grocery shopping experiences of people living in northern Canada. METHODS: We employed two methodological approaches to assess northern retail food environments. First, we mapped food retailers in the North to examine the breadth of retail competition in the provincial Norths, focussing specifically on those communities without year-round road access. Second, we surveyed people living in communities in northern Canada about their retail and shopping experiences. RESULTS: Fifty-four percent of communities in the provincial Norths and Far North without year-round road access did not have a grocery store that competed with the NWC. The provinces with the highest percentage of northern communities without retail competition were Ontario (87%), Saskatchewan (83%) and Manitoba (72%). Respondents to the survey (n = 92) expressed concern about their shopping experiences in three main areas: the cost of food, food quality and freshness, and availability of specific foods. CONCLUSION: There is limited retail competition in the provincial Norths. In Manitoba, Saskatchewan and Ontario, the NWC has no store competition in at least 70% of northern communities. Consumers living in northern Canada find it difficult to afford nutritious foods and would like access to a wider selection of perishable foods in good condition.

INTRODUCTION: Cet article porte sur l'environnement de la vente d'aliments dans les collectivités des Premières nations du nord des provinces, en particulier sur la concurrence éventuelle dans la vente au détail de la North West Company (NWC) ainsi que sur les expériences d'achats alimentaires de la population vivant dans le Nord canadien. MÉTHODOLOGIE: Nous avons utilisé deux méthodologies pour évaluer l'environnement alimentaire de la vente au détail dans le Nord. D'abord, nous avons cartographié les détaillants en alimentation du Nord afin d'examiner le degré de concurrence au détail dans les régions nordiques, en prêtant une attention particulière aux collectivités qui ne sont pas accessibles à l'année par la route. Ensuite, nous avons enquêté auprès des personnes vivant dans les collectivités du Nord canadien à propos de leurs expériences d'achat au détail et de magasinage. RÉSULTATS: Cinquante-quatre pour cent des collectivités du nord des provinces et du Grand Nord n'avaient aucune épicerie en concurrence avec la NWC. Les provinces comptant les plus fortes proportions de collectivités nordiques sans concurrence dans la vente au détail étaient l'Ontario (87 %), la Saskatchewan (83 %) et le Manitoba (72 %). Les participants au sondage (n = 92) ont fait état de leurs préoccupations quant à leurs expériences d'achat dans trois grands secteurs : le coût des aliments, la qualité et la fraîcheur des aliments et la disponibilité de certains aliments. CONCLUSION: La concurrence dans la vente au détail est limitée dans le nord des provinces. Au Manitoba, en Saskatchewan et en Ontario, la NWC ne fait face à aucune concurrence dans au moins 70 % des collectivités nordiques. Les consommateurs du Nord canadien considèrent que les aliments nutritifs sont peu abordables, et ils souhaitent avoir accès à un plus grand choix d'aliments périssables en bon état.

ANTHRAX IN THE MACKENZIE WOOD BISON (BISON BISON ATHABASCAE) POPULATION: 2012 ANTHRAX OUTBREAK AND HISTORICAL EXPOSURE IN NONOUTBREAK YEARS.

Anthrax, caused by the spore-forming bacterium Bacillus anthracis, poses a threat to wood bison (Bison bison athabascae) conservation. We used descriptive epidemiology to characterize a large outbreak of anthrax in the Mackenzie bison population in the Northwest Territories, Canada, in 2012 and investigated historical serologic exposure of the bison to the bacterium in nonoutbreak years. Between late June and early August 2012, 451 bison carcasses were detected; mortality peaked from 13-19 July. A substantial number of calves, yearlings, and adult females died in the 2012 outbreak, unlike in two previous anthrax outbreaks in this population that killed mostly mature males. On the basis of the difference in estimates of population size prior to the outbreak (2012) and after the outbreak (2013), it is possible that not all dead bison were found during the outbreak. We assessed serologic history of exposure to B. anthracis by using samples from the Mackenzie wood bison population collected between 1986 and 2009. Overall, 87 of 278 samples were positive (31%). Seroprevalence was lower in females (18%, 10/55) than males (36%, 72/203). The highest proportion of positive submissions (90%) was from 1994, the year following the only anthrax outbreak within the historical data set. Both adult males and females had a higher likelihood of being seropositive than the younger age categories. There was a trend toward declining antibody levels between the 1993 and 2012 outbreak years.

Assessing clinical support and inter-professional interactions among front-line primary care providers in remote communities in northern Canada: a pilot study.

BACKGROUND: Primary care in remote communities in northern Canada is delivered primarily by nurses who receive clinical support from physicians in regional centres and the patient transportation system. To improve continuity, quality and access to care in remote northern communities, it is important to understand the perspectives of front-line providers and the complex challenges they face. OBJECTIVE: To design and implement a survey of primary care providers to identify issues relating to inter-professional communication, clinical support and patient evacuation. METHODS: In collaboration with the territorial government and regional health authority partners, we developed a 21-item self-administered questionnaire survey, which could be completed online. The survey was sent to 218 physicians and nurses who were employed in the Northwest Territories (NWT) at the time of the survey and were involved in sending patients out of the community and/or receiving patients. The survey also contained an open-ended question at the end seeking comments regarding primary health care. RESULTS: The overall low response rate of 39% among nurses and 19% among physicians threatens the validity of the quantitative results. The majority of providers were satisfied with their ability to communicate with other providers in a timely manner, their freedom to make clinical decisions and their overall experience practicing in the NWT. The patient transfer system appears to work from both the sender and receiver perspectives. However, a common theme reported by nurses was that physicians providing clinical advice, especially short-term locums, were not familiar with the local situation, whilst physicians at the receiving end remarked that the clinical information provided to them often lacked clarity. CONCLUSIONS: Important lessons were learnt from the pilot study, especially in better engagement of providers in planning and dissemination. The questionnaire design and the online method of delivery were acceptable. Although important issues were identified, a larger definitive survey is needed to investigate them in the future.

The relationship between quality of work life and location of cross-training among obstetric nurses in urban northeastern Ontario, Canada: A population-based cross sectional study.

OBJECTIVES: The purpose of this mixed methods study was to examine the quality of work life of registered nurses working in obstetrics at 4 hospitals in northeastern Ontario and explore demographic and occupational factors related to nurses' quality of work life (QWL). MATERIAL AND METHODS: A stratified random sample of registered nurses (N = 111) selected from the 138 eligible registered nurses (80.4%) of staff in the labor, delivery, recovery, and postpartum areas at the 4 hospitals participated. Logistic regression analyses were used to consider QWL in relation to the following: 1) demographic factors, and 2) stress, employment status and educational attainment. RESULTS: In the logistic regression model, the odds of a higher quality of work life for nurses who were cross trained (nurses who can work across all areas of obstetrical care) were estimated to be 3.82 (odds ratio = 3.82, 95% confidence interval: 1.01-14.5) times the odds of a higher quality of work life for nurses who were not cross trained. CONCLUSIONS: This study highlights a relationship between quality of work life and associated factors including location of cross-training among obstetrical nurses in northeastern Ontario. These findings are supported by the qualitative interviews that examine in depth their relationship to QWL. Given the limited number of employment opportunities in the rural and remote regions, it is paramount that employers and employees work closely together in creating positive environments that promote nurses' QWL.

Chronic disease and chronic disease risk factors among First Nations, Inuit and Métis populations of northern Canada.

INTRODUCTION: Aboriginal populations in northern Canada are experiencing rapid changes in their environments, which may negatively impact on health status. The purpose of our study was to compare chronic conditions and risk factors in northern Aboriginal populations, including First Nations (FN), Inuit and Métis populations, and northern non-Aboriginal populations. METHODS: Data were from the Canadian Community Health Survey for the period from 2005 to 2008. Weighted multiple logistic regression models tested the association between ethnic groups and health outcomes. Model covariates were age, sex, territory of residence, education and income. Odds ratios (ORs) are reported and a bootstrap method calculated 95% confidence intervals (CIs) and p values. RESULTS: Odds of having at least one chronic condition was significantly lower for the Inuit (OR = 0.59; 95% CI: 0.43-0.81) than for non-Aboriginal population, but similar among FN, Métis and non-Aboriginal populations. Prevalence of many risk factors was significantly different for Inuit, FN and Métis populations. CONCLUSION: Aboriginal populations in Canada's north have heterogeneous health status. Continued chronic disease and risk factor surveillance will be important to monitor changes over time and to evaluate the impact of public health interventions.

TITRE: Maladies chroniques et facteurs de risque chez les membres des Premières Nations, les Inuits et les Métis du Nord canadien. INTRODUCTION: Les populations autochtones du Nord canadien subissent des changements rapides dans leur environnement, ce qui peut avoir des effets nuisibles sur leur état de santé. Nous avons voulu comparer les maladies chroniques et les facteurs de risque des populations autochtones du Nord canadien, à savoir les Premières nations, les Inuits et les Métis, avec les populations non autochtones de la même zone. MÉTHODOLOGIE: Les données sont tirées de l'Enquête sur la santé dans les collectivités canadiennes de 2005 à 2008. Des modèles de régression logistique multiple pondérée ont servi à analyser l'association entre les groupes ethniques et les résultats de santé. Les covariables du modèle étaient l'âge, le sexe, le territoire de résidence, le niveau de scolarité et le revenu. Nous présentons les rapports de cotes (RC) et nous avons utilisé la méthode d'échantillonnage bootstrap pour calculer les intervalles de confiance (IC) à 95% et les valeurs p. RÉSULTATS: La probabilité d'avoir au moins une maladie chronique était significativement plus faible chez les Inuits (RC = 0,59; IC à 95 % : 0,43 à 0,81) que chez les non-Autochtones, mais elle était similaire chez les Premières nations, les Métis et les non-Autochtones. La prévalence de nombreux facteurs de risque était significativement différente chez les Inuits, les membres des Premières nations et les Métis. CONCLUSION: Les Autochtones du Nord canadien ont des états de santé hétérogènes. Le maintien d'une surveillance continue des maladies chroniques et des facteurs de risque va jouer un rôle important dans la mesure des évolutions et dans l'évaluation de l'impact des interventions en santé publique les concernant.

Access and benefits sharing of genetic resources and associated traditional knowledge in northern Canada: understanding the legal environment and creating effective research agreements.

BACKGROUND: Research in northern Canada focused on Aboriginal peoples has historically benefited academia with little consideration for the people being researched or their traditional knowledge (TK). Although this attitude is changing, the complexity of TK makes it difficult to develop mechanisms to preserve and protect it. Protecting TK becomes even more important when outside groups become interested in using TK or materials with associated TK. In the latter category are genetic resources, which may have commercial value and are the focus of this article. OBJECTIVE: This article addresses access to and use of genetic resources and associated TK in the context of the historical power-imbalances in research relationships in Canadian north. DESIGN: Review. RESULTS: Research involving genetic resources and TK is becoming increasingly relevant in northern Canada. The legal framework related to genetic resources and the cultural shift of universities towards commercial goals in research influence the environment for negotiating research agreements. Current guidelines for research agreements do not offer appropriate guidelines to achieve mutual benefit, reflect unequal bargaining power or take the relationship between parties into account. CONCLUSIONS: Relational contract theory may be a useful framework to address the social, cultural and legal hurdles inherent in creating research agreements.
