RESUMO
Archaeological studies of pre-historic Arctic cultures are often limited to artefacts and architecture; such records may be incomplete and often do not provide a continuous record of past occupation. Here, we used lake sediment archives to supplement archaeological evidence to explore the history of Thule and Dorset populations on Somerset Island, Nunavut (Canada). We examined biomarkers in dated sediment cores from two ponds adjacent to abandoned Thule settlements (PaJs-3 and PaJs-13) and compared these to sediment cores from two ponds without past human occupation. Coprostanol and epicoprostanol, δ15N measurements, sedimentary chlorophyll a and the ratio of diatom valves to chrysophyte cysts were elevated in the dated sediment profiles at both sites during Thule and Dorset occupations. Periods of pronounced human impact during the Thule occupation of the site were corroborated by 14C-dated caribou bones found at both sites that identified intense caribou hunting between ca 1185 and 1510 CE. Notably, these sediment core data show evidence of the Dorset occupation from ca 200 to 500 CE at sites where archaeological evidence was heretofore lacking. We highlight the utility of lake sediments in assisting archaeological studies to better establish the timings, peak occupations and even lifestyle practices of the Dorset and Thule Arctic peoples.

Haemophilus influenzae serotype a (Hia) has recently emerged as an important cause of invasive disease in the North American Arctic and Sub-Arctic regions, mainly affecting young Indigenous children. In this study, we addressed the question of whether the prevalence of Hia and all H. influenzae in the nasopharynx differed between paediatric populations from regions with high versus low incidence of invasive Hia disease. Nasopharyngeal specimens from children with acute respiratory tract infections (ARTI) collected for routine diagnostic detection of respiratory viruses were analysed with molecular-genetic methods to identify and serotype H. influenzae. In Nunavut, a region with a high incidence of invasive Hia disease, all H. influenzae and particularly Hia were found in the nasopharynx of 60.6% and 3.0% children. In Southern Ontario (Hamilton region), where Hia invasive disease is rare, the frequencies of all H. influenzae and Hia detection were 38.5% and 0.6%, respectively. In both cohorts, non-typeable H. influenzae was prevalent (57.0% and 37.9%, respectively). Considering that Hia is an important cause of severe invasive disease in Nunavut children, 3% prevalence of Hia among children with ARTI can reflect continuing circulation of the pathogen in the Northern communities that may result in invasive disease outbreaks.

OBJECTIVE: The Cannabis Policy Study in the Territories (CPST) is an annual repeat cross-sectional study aiming to evaluate the impacts of cannabis legalization in the Canadian territories (Yukon, Northwest Territories, and Nunavut), where there is a paucity of data on cannabis use. This current study's objective was to describe the 2022 CPST, including methods, population prevalence estimates of cannabis use, and legal cannabis sources and perceptions in the territories. METHODS: The 2022 CPST includes 2462 respondents (aged 16 +) residing in the territories who either use or do not use cannabis. Respondents were recruited through mail-push-to-web invitations sent via licensed mailing lists, sampling from a near census of households in the territories. Population-weighted indicators of cannabis use are described. RESULTS: Past 12-month cannabis use was self-reported by 46.1%, and 21.8% self-reported daily/almost daily use. The most commonly used product types among past 12-month consumers were dried flower (73.4%), edibles (59.0%), and vape oils (35.7%). On average, 74.8% of cannabis products used in the past 12 months were from legal sources, though legal sourcing varied by product type (54.4â92.2%). Cannabis consumers reported favourable perceptions of legal compared to illegal cannabis products regarding quality, convenience, and safety, but a lesser extent for price. CONCLUSION: Cannabis use is highly prevalent in the territories, particularly daily/almost daily use, and legal market penetration is high despite region remoteness. Following cannabis legalization, monitoring cannabis use prevalence and patterns in remote regions is important for informing the development of harm reduction and prevention initiatives that consider the unique needs of these regions.
RéSUMé: OBJECTIF: L'Étude sur les politiques relatives au cannabis dans les territoires (Cannabis Policy Study in the Territories â CPST) est une étude transversale annuelle qui a pour but d'évaluer les répercussions de la légalisation du cannabis dans les territoires canadiens (Yukon, Territoires du Nord-Ouest et Nunavut), où il existe peu de données sur la consommation de cannabis. L'objectif de la présente étude était de décrire l'étude CPST de 2022, y compris la méthodologie, les estimations de la prévalence de la consommation de cannabis au sein de la population, ainsi que les sources et les perceptions du cannabis vendu légalement dans les territoires. MéTHODES: L'étude CPST menée en 2022 a consisté à interroger 2 462 personnes âgées de 16 ans et plus qui résident dans les territoires. Les répondants incluent des personnes qui consomment du cannabis et d'autres qui n'en consomment pas. Les répondants ont été recrutés au moyen d'invitations envoyées par la poste à partir de listes d'envoi autorisées. Les échantillons ont été effectués à partir d'un quasi-recensement des ménages qui résident dans les territoires. Les indicateurs pondérés en population de la consommation de cannabis sont décrits. RéSULTATS: Au cours des 12 derniers mois, le pourcentage d'autodéclarations de consommation de cannabis était de 46,1 %, et 21,8 % des répondants ont déclaré consommer quotidiennement ou presque. Les produits les plus couramment utilisés par les consommateurs au cours des 12 derniers mois étaient les fleurs séchées (73,4 %), les produits comestibles (59,0 %) et les huiles de vapotage (35,7 %). En moyenne, 74,8 % des produits de cannabis consommés au cours des 12 derniers mois provenaient de sources légales, bien que l'approvisionnement légal varie selon le type de produit (de 54,4 % à 92,2 %). Les consommateurs de cannabis ont déclaré percevoir favorablement les produits de cannabis vendus légalement comparativement aux produits vendus illégalement en ce qui a trait à la qualité, à la commodité et à la sécurité, mais dans une moindre mesure en matière de prix. CONCLUSION: La consommation de cannabis est très répandue dans les territoires, en particulier la consommation quotidienne ou presque quotidienne. De plus, la pénétration du marché des produits vendus légalement est élevée malgré l'éloignement des régions. À la suite de la légalisation du cannabis, la surveillance de la prévalence et des tendances de consommation du cannabis dans les régions éloignées fournit des renseignements importants pour l'élaboration d'initiatives de réduction des méfaits et de prévention qui tiennent compte des besoins uniques de ces régions.

In the recent monitoring guidelines released by the Arctic Monitoring and Assessment Program's Litter and Microplastic Expert Group, Arctic salmonids were recommended as an important species for monitoring plastics in Arctic ecosystems, with an emphasis on aligning microplastic sampling and analysis methods in Arctic fishes. This recommendation was based on the minimal documentation of microplastics in Northern fishes, especially Arctic salmonids. In response, we worked collaboratively with local partners to quantify and characterize microplastics in Arctic char, Salvelinus alpinus, and their habitats in a commercial fishery near Iqaluktuuttiaq (Cambridge Bay), Nunavut. We sampled Arctic char, surface water, and benthic sediments within their summer foraging habitat at Palik (Byron Bay). We found microplastics in 95 % of char with an average of 26 (SD ± 19) particles per individual. On average, surface water samples had 23 (SD ± 12) particles/L and benthic sediment <1 particles/gww. This is the first documentation of plastic pollution in Arctic char and their coastal habitats. Future work should evaluate seasonal, temporal and spatial trends for long-term monitoring of microplastics in Arctic fishes and their habitats.

The goal of this study was to examine and address critical knowledge gaps and develop an understanding of both the positive and negative societal outcomes resulting from the public health measures associated with the COVID-19 pandemic in Nunavut and the interventions being undertaken to promote positive well-being. Data collection for this study included narrative, in-person interviews in Iqaluit, Rankin Inlet, Baker Lake, and Cambridge Bay between September 2022 and January 2023. A total of 70 participants were interviewed for this study. Community highlighted challenges, such as crowding and food insecurity, and concern for the collective wellbeing of the community. Strengths included financials supports, food sharing, and maintaining community connections over a distance. Recommendations included a focus on holistic health such as 1) public education and awareness about communicable disease, 2) financial supports, 3) housing, 4) access to healthcare, 5) focus on Inuit Qaujimajatuqangit, 6) mental-health and addiction supports, and 7) community spaces. Community members described both strengths and challenges they believe impacted their experiences and service delivery as well as recommendations for the future.

The Arctic is the fastest warming biome on the planet, and environmental changes are having striking effects on freshwater ecosystems that may impact the regional carbon cycle. The metabolic state of Arctic lakes is often considered net heterotrophic, due to an assumed supply of allochthonous organic matter that supports ecosystem respiration and carbon mineralization in excess of rates of primary production. However, lake metabolic patterns vary according to regional climatic characteristics, hydrological connectivity, organic matter sources and intrinsic lake properties, and the metabolism of most Arctic lakes is unknown. We sampled 35 waterbodies along a connectivity gradient from headwater to downstream lakes, on southern Victoria Island, Nunavut, in an area characterized by low precipitation, organic-poor soils, and high evaporation rates. We evaluated whether lakes were net autotrophic or heterotrophic during the open water period using an oxygen isotopic mass balance approach. Most of the waterbodies were autotrophic and sites of net organic matter production or close to metabolic equilibrium. Autotrophy was associated with higher benthic primary production, as compared to its pelagic counterpart, due to the high irradiance reaching the bottom and efficient internal carbon and nutrient cycling. Highly connected midstream and downstream lakes showed efficient organic matter cycling, as evidenced by the strong coupling between gross primary production (GPP) and ecosystem respiration, while decoupling was observed in some headwater lakes with significantly higher GPP. The shallow nature of lakes in the flat, arid region of southern Victoria Island supports net autotrophy in most lakes during the open water season. Ongoing climate changes that lengthen the ice-free irradiance period and increase rates of nutrient evapoconcentration may further promote net autotrophy, with uncertain long-term effects for lake functioning.

Eekeeluak Avalak, an 18-year-old Inuk wrestler who won the first-ever gold medal for Nunavut at the Canada Summer Games in 2022, dedicated his win to his late brother who died by suicide in 2015. Avalak openly attributed sport - specifically wrestling - to saving his own life. This story raises important questions about the role of sport and traditional games in Inuit suicide prevention strategies. Few studies have examined the role of sport or traditional games in Inuit suicide prevention strategies. In an attempt to reduce Inuit suicide rates, in addition to the National Inuit Prevention Strategy, three of the four land claim regions that constitute Inuit Nunangat have suicide prevention strategies. In this study, we used settler colonial theory, critical Inuit studies, and content analysis to examine if and how sport and Inuit traditional games are identified as prevention tools in these Inuit suicide prevention strategies. The results demonstrate that sport and traditional games have largely been overlooked as protective factors in current Inuit-wide and land-claim specific suicide prevention strategies. Moving forward, evidence-based and community-driven approaches could be funded, created, implemented, and evaluated as culturally-safe Inuit mental health intervention models to address the disproportionately high suicide rates among Inuit in Inuit Nunangat.

Across Canada, the COVID-19 pandemic placed considerable stress on territorial and provincial healthcare systems. For Nunavut, the need to continue to provide access to critical care to its citizens meant that medical travel to provincial points of care (Edmonton, Winnipeg and Ottawa) had to continue through the pandemic. This complexity created challenges related to the need to keep Nunavut residents safe while accessing care, and to manage the risk of outbreaks in Nunavut resultant from patients returning home. A number of strategies were adopted to mitigate risk, including the expansion of virtual care, self-isolation requirements before returning from Winnipeg, and a level of cross-jurisdictional coordination previously unprecedented. Structural limitations in Nunavut however limited opportunities to expand virtual care, and to allow providers from Manitoba to access the Nunavut's electronic medical records of patients requiring follow up. Thus, known and long-standing issues exacerbated vulnerabilities within the Nunavut healthcare system. We conclude that addressing cross-jurisdictional issues would be well served by the development of a more formal Nunavut-Manitoba agreement (with similar agreements with Ontario and Alberta), outlining mutual obligations and accountabilities.

Circumpolar regions face unique challenges in establishing and maintaining mental health care systems, including forensic psychiatry services. The scarcity of data and lack of evidence concerning the forensic psychiatry patient (FPP) populations of Nunavut and Greenland exacerbates the challenges of informing best practices and healthcare planning. By comparing the prevalence of forensic psychiatry patients, the mental health care services, and the legislation in these two relatively similar but unique regions, insight may be gained that can help inform healthcare planning. This cross-sectional study includes all forensic psychiatry in- and outpatients in one year from Nunavut (2018) and on February 29, 2020, in Greenland. The Greenland sample (n = 93) was nearly four times larger than the Nunavut sample (n = 15) at the population level. Despite considerable differences in forensic legislation and service supply, the forensic psychiatry patients in the two areas share several similarities. A total of 87% (n = 13) in the Nunavut sample were diagnosed with a DSM-5 schizophrenia spectrum disorder or other psychotic disorder. In Greenland, 82% (n = 76) were diagnosed with an ICD-10 F2 diagnosis (schizophrenia, schizotypal and delusional disorders). Approximately 2/3 of the patients in both populations were diagnosed with substance use disorder, and 60% of the Nunavut FPP received long-acting antipsychotic injections versus 62% in Greenland. Nearly half of the FPPs in both populations had never been convicted prior to entering the forensic psychiatry system; Nunavut 45% versus Greenland 47%. A substantial proportion of Greenlandic FPPs were outpatients compared to Nunavut (83% versus 47%). This study is an essential first step toward describing a Model of Care for forensic psychiatry patients in circumpolar regions; furthermore, the clinical similarities between the two populations provide support for future joint Arctic research and the inclusion of artic forensic patients in international studies.

Oil spilled in marine environments can settle to the seafloor through aggregation and sedimentation processes. This has been predicted to be especially relevant in the Arctic due to plankton blooms initiated by melting sea ice. These conditions exist in the Kivalliq region in Nunavut, Canada, where elevated shipping traffic has increased the risk of accidental spills. Experimental microcosms combining surface sediment and crude oil were incubated at 4 °C over 21 weeks to evaluate the biodegradation potential of seabed microbiomes. Sediments sampled near the communities of Arviat and Chesterfield Inlet were assessed for biodegradation capabilities by combining hydrocarbon geochemistry with 16S rRNA gene and metagenomic sequencing, revealing decreased microbial diversity but enrichment of oil-degrading taxa. Alkane and aromatic hydrocarbon losses corresponded to detection of genes and genomes that encode enzymes for aerobic biodegradation of these compounds, pointing to the utility of marine microbiome surveys for predicting the fate of oil released into Arctic marine environments.

The North has experienced unprecedented rates of warming over the past few decades, impacting the survival and development of insects and the pathogens that they carry. Since 2019, Arctic foxes from Canada (Nunavut) have been observed with fur loss inconsistent with natural shedding of fur. Adult lice were collected from Arctic foxes from Nunavut (n = 1) and Svalbard (n = 2; Norway) and were identified as sucking lice (suborder Anoplura). Using conventional PCR targeting the mitochondrial cytochrome c oxidase subunit 1 gene (cox1), lice from Canada and Svalbard were 100% similar (8 pooled samples from Nunavut and 3 pooled samples from Svalbard), indicating that there is potential gene flow between ectoparasites on Scandinavian and North American Arctic fox populations. The cox1 sequences of Arctic fox lice and dog sucking lice (Linognathus setosus) had significant differences (87% identity), suggesting that foxes may harbour a cryptic species that has not previously been recognised. Conventional PCR targeting the gltA gene for Bartonella bacteria amplified DNA from an unknown gammaproteobacteria from two pooled louse samples collected from Svalbard foxes. The amplified sequences were 100% identical to each other but were only 78% like Proteus mirabilis reported in GenBank (CP053614), suggesting that lice on Arctic foxes may carry unique microorganisms that have yet to be described.

BACKGROUND: In Nunavut, where 70% of children are food insecure, many households rely on school breakfast or community food programmes for nourishment. The COVID-19 pandemic and resulting policies to reduce the spread of the disease have the potential to exacerbate existing issues, including increasing food insecurity in households. Funding programmes were implemented to limit the impact of public-health measures on household and community food security. The overall effects of the actions are not yet understood. METHODS: This project used a qualitative approach to examine the determinants of food security and sovereignty and the impact of the COVID-19 pandemic policy responses on these determinants in Arviat and Iqaluit. Narrative analysis applied within a relational epistemology was used to describe the experiences of community members in Iqaluit and Arviat during the COVID-19 pandemic. RESULTS: Seven participants were interviewed in Iqaluit (n=3) and Arviat (n=4). Key themes included the importance of decolonisation for food sovereignty, the importance of food sharing to communities and the resilience of communities during COVID-19. Community members wished to see greater support and strengthening of the country (locally harvested) food economy to increase knowledge of food and harvesting skill, and for communities to find ways to reach residents who may fall through the cracks during times of need or crisis. CONCLUSIONS: This study is one of the first to document Nunavummiut experiences and perspectives of food security and sovereignty in Arviat and Iqaluit during the COVID-19 pandemic.

In Canada, there are vast differences between the state of accommodation/housing, health, social inequalities, education and economic conditions for people in the northern and southern regions of the country. Overcrowding in Inuit Nunangat is a direct result of the promises made by past government policy that led to Inuit people settling in sedentary communities in the North on the understanding that they would be provided with social welfare. However, these welfare programmes proved to be either insufficient or non-existent for Inuit people. Therefore, Inuit are living in overcrowded homes in Canada, resulting in a severe housing shortage, poor-quality housing and homelessness. This has led to the spread of contagious diseases, mould, mental-health issues, gaps in education for children, sexual and physical violence, food insecurity and adverse challenges for the youth of Inuit Nunangat. This paper proposes several actions to ease the crisis. First, funding should be stable and predictable. Next, there should be ample construction of transitional homes which could be used to accommodate people before moving them into proper public housing. Policies regarding staff housing should be amended, and if possible, these vacant staff houses could provide shelter to eligible Inuit people, which could help lessen the housing crisis. The advent of COVID-19 has made the issue of affordable and safe housing more serious because without safe housing, the health, education and well-being of the Inuit people in Inuit Nunangat are in peril. This study focuses on how the governments of Canada and Nunavut are dealing with this issue.

INTERVENTION: In 2014-2015, more than 400 public housing units were constructed in Nunavut and Nunavik, two of the four Inuit regions in Canada. This provided the opportunity to assess the impact of improved housing conditions from a population health perspective in 12 Inuit communities where housing needs were the most severe. The aim of the research is to examine the associations between changes in housing conditions and changes in psychological distress pre-post rehousing. METHODS: A pre-post uncontrolled study was conducted in collaboration with Nunavut- and Nunavik-based organizations. Applicants at the top of public housing waitlists were recruited by local housing officers; participants completed questionnaires 1-6 months before rehousing, and 15-18 months after. Change in psychological distress was measured with the Kessler 6-item scale. Changes in three housing measures were examined: number of adults per household, number of children per household, and sense of home score. For each housing measure, a categorical variable stratified participants into three categories. The reference category included participants reporting significant change in the concerned housing measure; the two other categories included participants reporting little or no change. Associations were tested with linear multilevel regression models for change. RESULTS: A total of 102 Inuit adults completed the study. A reduction in the number of adults per household (living with 2 adults or less after rehousing) and an increase in sense of home were associated with significant decline in psychological distress pre-post rehousing (p < 0.001). CONCLUSION: Increased investments leading to such improvements in housing circumstances are promising ways to promote mental health in Inuit regions.
RéSUMé: INTERVENTION: En 2014-2015, plus de 400 logements sociaux ont été construits au Nunavut et au Nunavik, deux des quatre régions inuites du Canada, permettant ainsi d'évaluer l'impact de l'amélioration des conditions de logement sur la santé. Cette étude vise à examiner les associations entre les changements dans les conditions de logement et les changements dans la détresse psychologique avant et après le déménagement, dans 12 communautés inuites où les besoins en logement étaient les plus criants. MéTHODES: Une étude pré-post non contrôlée a été menée en collaboration avec des organisations du Nunavut et du Nunavik. Les participants figurant en tête des listes d'attente pour le logement social ont rempli les questionnaires de recherche 1-6 mois avant le déménagement et 15-18 mois après. Les changements de la détresse psychologique ont été mesurés à l'aide de l'échelle Kessler 6-item. Les changements des trois conditions de logement suivantes ont été examinés : le nombre d'adultes par ménage, le nombre d'enfants par ménage et le sentiment d'avoir un chez-soi. Pour chaque condition de logement, une variable catégorielle a été créée pour stratifier les participants ayant rapporté des changements (référence) et les participants n'ayant rapporté que peu ou pas de changement. Les associations ont été testées avec des modèles de régression linéaire multiniveaux. RéSULTATS: Un total de 102 adultes Inuit ont complété l'étude. Une réduction du nombre d'adultes par ménage (vivre avec 2 adultes ou moins après le déménagement) et une augmentation du sentiment d'avoir un chez-soi étaient associées à une baisse significative de la détresse psychologique (p < 0,001). CONCLUSION: Des investissements accrus menant à de telles améliorations des conditions de logement représentent une avenue prometteuse pour promouvoir la santé mentale dans les régions inuites.

To assess the effect of eConsultation in providing Orthopaedic Surgery specialist service to patients in Nunavut. A cross-sectional study of 161 Orthopaedic Surgery consultations received from primary care providers (PCPs) in Nunavut via the Champlain Building Access to Specialist service through eConsult (BASETM) service over the 2-year period from January 2017 to December 2018. Data captured were: reason for consultation, impact of advice on referral, perceived value to the PCPs and time spent. eConsult avoided unnecessary in-person consultation 62% of the time while catching 5% of the referrals that would have otherwise been missed. PCP referral behaviour was modified 48% of the time. 94% of eConsults were rated as valuable to PCPs in their practice and 100% of eConsults resulted in actionable advice. Further, eConsults took an average of 15.4 minutes of specialist time to complete, and the mean time from referral to response was 1.4 days. eConsultation spares unnecessary consultation to Orthopaedic Surgery, catches important referrals that would have otherwise been missed, decreases wait time, and may reduce cost in remote healthcare systems such as Nunavut.

BACKGROUND: The Qanuinngitsiarutiksait study aimed to develop detailed profiles of Inuit health service utilization in Manitoba, by Inuit living in Manitoba (approximately 1,500) and by Inuit from the Kivalliq region of Nunavut who travel to Manitoba to access care not available in Nunavut (approximately 16,000 per year). METHODS: We used health administrative data routinely collected in Manitoba for all services provided and developed an algorithm to identify Inuit in the dataset. This paper focused on health services used by Inuit from the Kivalliq for prenatal care and birthing. RESULTS: Our study found that approximately 80 percent of births to women from the Kivalliq region occur in Manitoba, primarily in Winnipeg. When perinatal care and birthing are combined, they constitute one third of all consults happening by Kivalliq residents in Manitoba. For scale, hospitalizations for childbirths to Kivalliq women about to only 5 percent of all childbirth-related hospitalizations in Manitoba. CONCLUSIONS: The practice of evacuating women from the Kivalliq for perinatal care and birthing is rooted in colonialism, rationalized as ensuring that women whose pregnancy is at high risk have access to specialized care not available in Nunavut. While defendable, this practice is costly, and does not provide Inuit women a choice as to where to birth. Attempts at relocating birthing to the north have proven complex to operationalize. Given this, there is an urgent need to develop Inuit-centric and culturally appropriate perinatal and birthing care in Manitoba.

The truncate soft-shell clam Mya truncata is an important source of country food for Inuit communities across the territory of Nunavut, Canada. M. truncata also plays an important role in marine ecosystems, yet there is little understanding of their life history and condition in Canadian Arctic waters. To provide a foundation on which aspects of the life history and condition of M. truncata of Baffin Island can be monitored in the future with a changing climate and fishery development, this study estimated size at maturity and provides insights into the spawning cycle and weight-length condition indices of clams from inner Frobisher Bay and the north shore of the Hudson Strait. Male and female M. truncata exhibited similar lengths at 50% attainment of sexual maturity, 31 mm and 32 mm shell length (SL), respectively. Most (77%) of the sexually mature M. truncata collected from inner Frobisher Bay in late August and 35% of clams collected from the Hudson Strait in early September were in the ripe stage of gonadal development. These results lead us to suggest a spring spawning season and that M. truncata invest in gonadal development for the next year's spawning during the late summer-early autumn ice-free season while phytoplankton concentrations are high. Dry bodyweight-SL relationships were used to show that M. truncata condition can differ significantly over small and large spatial scales based on plotted 95% confidence intervals.

This study explores the ways in which a rehousing intervention shapes the mental well-being of Inuit adults living in Nunavut, Canada, where the prevalence of core housing need is four times the national average. More specifically, it compares the housing experiences of participants who were rehoused in a newly built public housing unit, to the experiences of participants on the public housing waitlist. The study was developed in collaboration with organizations based in Nunavut and Nunavik. Semi-structured interviews were transcribed, and a deductive-inductive thematic analysis was performed based on Gidden's concept of ontological security, and Inuit-specific mental health conceptualization. Twenty-five Inuit adults participated (11 rehoused, 14 waitlist). Three themes were identified to describe how the subjective housing experiences of participants improved their mental well-being after rehousing: (1) refuge creation; (2) self-determination and increased control; (3) improved family dynamics and identity repair. Implicit to these themes are the contrasting housing experiences of participants on the waitlist. Construction initiatives that increase public housing stock and address gaps in the housing continuum across Inuit regions could promote well-being at a population level. However, larger socio-economic problems facing Inuit may hamper beneficial processes stemming from such interventions.

BACKGROUND: Nunavut, the northernmost Arctic territory of Canada, experienced three community outbreaks of the coronavirus disease 2019 (COVID-19) from early November 2020 to mid-June 2021. We sought to investigate how non-pharmaceutical interventions (NPIs) and vaccination affected the course of these outbreaks. METHODS: We used an agent-based model of disease transmission to simulate COVID-19 outbreaks in Nunavut. The model encapsulated demographics and household structure of the population, the effect of NPIs, and daily number of vaccine doses administered. We fitted the model to inferred, back-calculated infections from incidence data reported from October 2020 to June 2021. We then compared the fit of the scenario based on case count data with several counterfactual scenarios without the effect of NPIs, without vaccination, and with a hypothetical accelerated vaccination program whereby 98% of the vaccine supply was administered to eligible individuals. RESULTS: We found that, without a territory-wide lockdown during the first COVID-19 outbreak in November 2020, the peak of infections would have been 4.7 times higher with a total of 5,404 (95% CrI: 5,015-5,798) infections before the start of vaccination on January 6, 2021. Without effective NPIs, we estimated a total of 4,290 (95% CrI: 3,880-4,708) infections during the second outbreak under the pace of vaccination administered in Nunavut. In a hypothetical accelerated vaccine rollout, the total infections during the second Nunavut outbreak would have been 58% lower, to 1,812 (95% CrI: 1,593-2,039) infections. Vaccination was estimated to have the largest impact during the outbreak in April 2021, averting 15,196 (95% CrI: 14,798-15,591) infections if the disease had spread through Nunavut communities. Accelerated vaccination would have further reduced the total infections to 243 (95% CrI: 222-265) even in the absence of NPIs. CONCLUSIONS: NPIs have been essential in mitigating pandemic outbreaks in this large, geographically distanced and remote territory. While vaccination has the greatest impact to prevent infection and severe outcomes, public health implementation of NPIs play an essential role in the short term before attaining high levels of immunity in the population.

While Inuit living in Nunavut have been advocating for decades for the return of birthing to their own communities, over two-third of births continue to occur outside of the territory. We conducted a literature review to answer the question, why has birthplace choice not been given back to Inuit yet. Based on our review we identified a number of factors impacting birthplace choice, including the organisation of the Nunavut medical system that is focused on primary health care and that cannot easily accommodate the potential clinical risks Western health care associates with birthing, often in isolation from socio-cultural risks; staffing vacancies and turn over in Nunavut, which creates challenges in continuity of care and in maintaining trust; and trends in Canada towards the medicalisation of birthing, which resulted in the displacement of traditional midwifery, and lately in the professionalisation of midwifery with training centres mostly located outside of Nunavut. We recognise that providing more options to birth in the north is complex. While birthing in the north as an option is a given objective, operationalising this objective in a consistent manner is likely going to be a challenge for years to come.
