BACKGROUND: Ethnic variation in abdominal fat distribution may explain differences in cardiometabolic risk between populations. However, the ability of anthropometric measures to quantify abdominal fat is not clearly understood across ethnic groups. The aim of this study was to investigate the associations between anthropometric measures and visceral (VAT) and subcutaneous abdominal adipose tissue (SAT) in Inuit, Africans and Europeans. METHODS: We combined cross-sectional data from 3 studies conducted in Greenland, Kenya and Denmark using similar methodology...

BACKGROUND: In Canada, active tuberculosis (TB) disease rates remain disproportionately higher among the Indigenous population, especially among the Inuit in the north. We used mathematical modeling to evaluate how interventions might enhance existing TB control efforts in a region of Nunavut. METHODS: We developed a stochastic, agent-based model of TB transmission that captured the unique household and community structure. Evaluated interventions included: (i) rapid treatment of active cases; (ii) rapid contact tracing; (iii) expanded screening programs for latent TB infection (LTBI); and (iv) reduced household density...

Diet is a major determinant of community composition in the human gut microbiome, and "traditional" diets have been associated with distinct and highly diverse communities, compared to Western diets. However, most traditional diets studied have been those of agrarians and hunter-gatherers consuming fiber-rich diets. In contrast, the Inuit of the Canadian Arctic have been consuming a traditional diet low in carbohydrates and rich in animal fats and protein for thousands of years. We hypothesized that the Inuit diet and lifestyle would be associated with a distinct microbiome...

A recent study conducted the first genome-wide scan for selection in Inuit from Greenland using SNP chip data. Here, we report that selection in the region with the second most extreme signal of positive selection in Greenlandic Inuit favored a deeply divergent haplotype that is closely related to the sequence in the Denisovan genome, and was likely introgressed from an archaic population. The region contains two genes, WARS2 and TBX15, and has previously been associated with adipose tissue differentiation and body-fat distribution in humans...

BACKGROUND: Arctic residents can be exposed to a wide range of contaminants through consumption of traditional (country) foods (i.e. food from wild animals and plants that are hunted, caught or collected locally in the Arctic). Yet these foods provide excellent nutrition, promote social cohesion, meet some spiritual needs for connectedness to the land and water, reinforce cultural ties, are economically important and promote overall good health for many. The risk and benefit balance associated with the consumption of traditional Arctic foods is complicated to communicate and has been referred to as the "Arctic Dilemma"...

The Kivalliq Inuit Centre (KIC), a boarding home in Winnipeg, Manitoba, is unique in its provision of a pilot prenatal education class and public health nursing services for Nunavummiut who are beneficiaries of the Nunavut Land Claim Agreement. Through a critical review of literature, policies and interviews related to evacuation for birth, we argue that the pilot at the KIC has the potential to play an important role in improving maternal child health for residents of Nunavut.

BACKGROUND: There is a dearth of literature to guide the development of community-based HIV and sexually transmitted infection (STI) prevention and sexual health promotion programs within Inuit communities. OBJECTIVE: The aim of this study was to create a dialogue with Inuit women to address the lack of information available to inform programming to improve the sexual health of Inuit women, their families, and their communities in the Canadian Arctic. DESIGN: This study used Indigenous methodologies and methods by drawing from Inuit Qaujimajatuqangit and postcolonial research theory in a framework of Two-Eyed Seeing, and using storytelling sessions to gather data...

BACKGROUND: Inuit youth are reported to experience considerably worse sexual and reproductive health and rights (SRHR) outcomes than Canadian youth in general, as evidenced through public health data on sexually transmitted infections, unintended young pregnancies and rates of sexual violence in Nunavut compared to national averages. Existing literature on Inuit SRHR has identified the impact of westernization and colonialism on health outcomes, though gaps remain in addressing youth- and community-specific experiences of SRHR...

Teen pregnancy is depicted around the world as an important cause of health disparities both for the child and the mother. Accordingly, much effort has been invested in its prevention and led to its decline in the northern hemisphere since the mid-1990s. Despite that, high rates are still observed in the circumpolar regions. As Inuit communities have granted better understanding of teenage pregnancy a priority for the coming years, this article comprehensively reviews this multidimensional issue. By depicting current prevalence, likely determinants and possible impacts documented among Inuit of Canada, Alaska and Greenland, and contrasting them to common knowledge that has emerged from other populations over the years, great gaps surface...

OBJECTIVE: High rates of sexually transmitted infections in the Arctic have been a focus of recent research, and youth are believed to be at greatest risk of infection. Little research has focused on understanding youth perspectives on sexual health. The goal of this study was to collect the perspectives of youth in Nunavut on sexual health and relationships with the intent of informing public health practice. METHOD: This qualitative research study was conducted within an Indigenous knowledge framework with a focus on Inuit ways of knowing...

BACKGROUND: Despite abundant evidence that socio-economic status (SES) is a fundamental determinant of health, there is a dearth of research examining association between SES, measured at the individual and community levels, and cardiovascular risk factors and morbidity among indigenous populations. OBJECTIVES: To examine the influence of individual-level and community-level SES on systolic and diastolic blood pressure among Greenlandic Inuit. METHODS: Multilevel analysis of cross-sectional data from the Inuit Health in Transition - Greenland Survey, to which 3,108 Greenlandic Inuit aged 18 years and older participated...

Developing Canadian hydroelectric resources is a key component of North American plans for meeting future energy demands. Microbial production of the bioaccumulative neurotoxin methylmercury (MeHg) is stimulated in newly flooded soils by degradation of labile organic carbon and associated changes in geochemical conditions. We find all 22 Canadian hydroelectric facilities being considered for near-term development are located within 100 km of indigenous communities. For a facility in Labrador, Canada (Muskrat Falls) with planned completion in 2017, we probabilistically modeled peak MeHg enrichment relative to measured baseline conditions in the river to be impounded, downstream estuary, locally harvested fish, birds and seals, and three Inuit communities...

OBJECTIVE: Past publications have highlighted an excess rheumatic disease incidence and prevalence in indigenous populations of Canada (First Nations, Inuit, and Métis), and the United States of America (Alaska Native and American Indian). We have updated these reviews and expanded the scope to include New Zealand (Maori) and Australia (Aborigine) indigenous populations. METHODS: We performed a broad search using medical literature databases, indigenous specific online indexes, and government websites to identify publications reporting the incidence and/or prevalence of arthritis conditions (rheumatoid arthritis, spondyloarthropathies, gout, osteoarthritis, systemic autoimmune rheumatic diseases, and juvenile idiopathic arthritis) in the indigenous populations of Canada, America, New Zealand, and Australia...

The genetic consequences of population bottlenecks on patterns of deleterious genetic variation in human populations are of tremendous interest. Based on exome sequencing of 18 Greenlandic Inuit here we show that the Inuit have undergone a severe ~20,000 year long bottleneck. This has led to a markedly more extreme distribution of allele frequencies than seen for any other human population, making the Inuit the perfect population for investigating the effect of a bottleneck on patterns of deleterious variation...

Extending the group affirmation literature to the domain of prejudice, this study investigated whether group affirmation buffers the self-esteem of women exposed to blatant sexism. In accordance with Self-Affirmation Theory (Steele, 1988) and group affirmation research (Sherman et al., 2007), we hypothesized that when one aspect of the collective self is threatened (gender identity), self-esteem can be maintained via the affirmation of an alternative aspect of the collective self. In a 2×2 between-participants design, female students were randomly assigned to read about discrimination directed toward women or a non-self-relevant disadvantaged group (the Inuit)...

First Nations, Métis, and Inuit (FNMI) youth are disproportionately affected by a range of negative health outcomes including poor emotional and psychosocial well-being. At the same time, there is increasing awareness of culturally-specific protective factors for these youth, such as cultural connectedness and identity. This article reports the findings of a mixed-methods, exploratory longitudinal study on the effects of a culturally-relevant school-based mentoring program for FNMI youth that focuses on promoting mental well-being and the development of cultural identity...

REVIEW
Lawrence Leung
Diabetes mellitus is a chronic disease of major global health concern due to its increasing prevalence in both developing and developed counties, with a projection increase of 214% from the year 2000 to 2030. Among the Aboriginal population of Canada (which includes the First Nations, Inuit and Metis), diabetes mellitus contribute significantly to their higher morbidity and increased health disparity when compared to the non-Aboriginal Canadians. In view of this, the Federal Government of Canada had launched the Aboriginal Diabetes Initiative (ADI) in 1999 as part of the bigger Canadian Diabetes Strategy to provide a better framework for surveillance, public education and community-based management of diabetes...

The demographic history of Greenland is characterized by recurrent migrations and extinctions since the first humans arrived 4,500 years ago. Our current understanding of these extinct cultures relies primarily on preserved fossils found in their archaeological deposits, which hold valuable information on past subsistence practices. However, some exploited taxa, though economically important, comprise only a small fraction of these sub-fossil assemblages. Here we reconstruct a comprehensive record of past subsistence economies in Greenland by sequencing ancient DNA from four well-described midden deposits...

AIM: HIV infections occur across the Arctic but their incidence among aboriginal populations varies vastly. At the time this research was initiated there were no data on their occurrence, risk of HIV/AIDS or preventive strategies among Inuit living in the Nunavut territory of Canada. This review is the first to assess the risk of HIV infection among Inuit and evaluate current prevention strategies among Canadian-Inuit populations. MATERIALS AND METHODS: The contents of this article are based on the author's own research, undertaken during 3 visits to the Canadian Arctic and the published literature...
