OBJECTIVE: To measure vitamin D status and estimate factors associated with serum 25-hydroxyvitamin D (25(OH)D) in Nunavimmiut (Inuit living in Nunavik) adults in 2017. DESIGN: Data were from Qanuilirpitaa? 2017 Nunavik Inuit Health Survey, a cross-sectional study conducted in August-October 2017. Participants underwent a questionnaire, including an FFQ, and blood samples were analysed for total serum 25(OH)D. SETTING: Nunavik, northern Québec, Canada. PARTICIPANTS: A stratified proportional model was used to select respondents, including 1,155 who identified as Inuit and had complete data. RESULTS: Geometric mean serum vitamin D levels were 65·2 nmol/l (95 % CI 62·9-67·6 nmol/l) among women and 65·4 nmol/l (95 % CI 62·3-68·7 nmol/l) among men. The weighted prevalence of serum 25(OH)D < 75 nmol/l, <50 nmol/l <30 nmol/l was 61·2 %, 30·3 % and 7·0 %, respectively. Individuals who were older, female, lived in smaller and/or more southerly communities and/or consumed more country (traditional) foods were at a reduced risk of low vitamin D status. Higher consumption of wild fish was specifically associated with increased serum 25(OH)D concentration. CONCLUSION: It is important that national, regional and local policies and programs are in place to secure harvest, sharing and consumption of nutritious and culturally important country foods like Arctic char and other wild fish species, particularly considering ongoing climate change in the Arctic which impacts the availability, access and quality of fish as food.

BACKGROUND: Fish and seafood play an important role in improving food security in Inuit Nunangat. Therefore, this scoping review aims to explore (1) what topics and/or themes have been widely explored in the literature related to barriers and pathways linking fish and seafood to food security; (2) where research, policy, and action gaps exist; and (3) how fisheries currently contribute to food security. METHODS: A systematic search of peer-reviewed articles was conducted using six databases. Articles were screened by two independent reviewers. Eligible studies included primary research conducted in Inuit Nunangat that explored the roles of fish and seafood in food security. RESULTS: Thirty-one articles were included for review. Overall, we found that fisheries can influence food security through direct pathways (e.g., consuming fish for nutrition), and through indirect pathways such as increasing household purchasing power (e.g., through employment). Research indicated that policies relating to wildlife and fisheries management need to be integrated with food and health policies to better address food insecurity in Inuit Nunangat. CONCLUSION: Future research is needed to establish a more robust understanding of the explicit mechanisms that fish and seafood harvest and/or the participation in commercial fisheries alleviates household food insecurity.

BACKGROUND: Academic research on food security in Inuit Nunangat and Alaska frequently adopts the Food and Agriculture Organization of the United Nations' working definition of food security and Western conceptualisations of what it means to be 'food secure'. However, in 2014, the Alaskan branch of the Inuit Circumpolar Council (ICC) stated that academic and intergovernmental definitions and understandings 'are important, but not what we are talking about when we say food security'. The organisation subsequently developed its own conceptualisation and definition: the Alaskan Inuit Food Security Conceptual Framework (AIFSCF), which in 2020 received informal assent by ICC-Canada. AIM: This protocol establishes a review strategy to examine how well academic research reflects Inuit conceptualisations and understandings of food security, as outlined in the AIFSCF. METHODS: Review structure and reporting will be completed according to adapted RepOrting standards for Systematic Evidence Syntheses (ROSES) guidelines. A comprehensive search strategy will be used to locate peer-reviewed research from Medline, Scopus, Web of Science and the Arctic and Antarctic Regions (EBSCO) databases. Dual reviewer screening will take place at the abstract, title, and full-text stages. Different study methodologies (qualitative, quantitative, and mixed methods) will be included for review, on the proviso that articles identify drivers of food security. An a priori coding framework will be applied by a single reviewer to extract data on publication characteristics, methods and article aims. Deductive thematic content analysis will then identify the frequency and precedence afforded within literature to the drivers and dimensions of food security identified by the AIFSCF.

OBJECTIVES: Country (traditional) foods are integral to Inuit culture, but market food consumption is increasing. The Qanuilirpitaa? 2017 Nunavik Health Survey (Q2017) reported similar country food consumption frequency compared to that in 2004; however, examining food items individually does not account for diet patterns, food accessibility, and correlations between food items. Our objective was to identify underlying dietary profiles and compare them across sex, age, ecological region, and food insecurity markers, given the links among diet, health, and sociocultural determinants. METHODS: Food frequency and sociodemographic data were derived from the Q2017 survey (N = 1176). Latent profile analysis identified dietary profiles using variables for the relative frequencies of country and market food consumption first, followed by an analysis with those for country food variables only. Multinomial logistic regression examined the associations among dietary profiles, sociodemographic factors, and food insecurity markers (to disassociate between food preferences and food access). RESULTS: Four overall dietary profiles and four country food dietary profiles were identified characterized by the relative frequency of country and market food in the diet. The patterns were stable across several sensitivity analyses and in line with our Inuit partners' local knowledge. For the overall profiles, women and adults aged 30-49 years were more likely to have a market food-dominant profile, whereas men and individuals aged 16-29 and 50+ years more often consumed a country food-dominant profile. In the country food profiles, Inuit aged 16-29 years were more likely to have a moderate country food profile whereas Inuit aged 50+ were more likely to have a high country food-consumption profile. A low country and market food-consumption profile was linked to higher prevalence of food insecurity markers. CONCLUSION: We were able to identify distinct dietary profiles with strong social patterning. The profiles elucidated in this study are aligned with the impact of colonial influence on diet and subsequent country food promotion programs for Inuit youth. These profiles will be used for further study of nutritional status, contaminant exposure, and health to provide context for future public health programs.
RéSUMé: OBJECTIFS: Les aliments traditionnels font partie intégrante de la culture inuite, mais la consommation d'aliments du marché est en augmentation. L'enquête de santé des Inuit Qanuilirpitaa? réalisée en 2017 (Q2017) a mis en évidence que la fréquence de consommation d'aliments traditionnels était similaire à celle rapportée en 2004. Or, les fréquences de consommation des aliments pris individuellement ne tiennent pas compte des habitudes alimentaires, de l'accessibilité des aliments et des corrélations entre les aliments consommés. Notre objectif était d'identifier les profils alimentaires sous-jacents et de les comparer selon le sexe, l'âge, la région écologique et les marqueurs d'insécurité alimentaire, étant donné le lien entre l'alimentation, la santé et les déterminants socioculturels. MéTHODES: Les données sur les fréquences alimentaires et sociodémographiques sont issues de l'enquête Q2017 (N=1176). L'analyse des profils latents a permis d'identifier des profils alimentaires en utilisant les variables pour les fréquences relatives de la consommation d'aliments traditionnels et du marché et uniquement celles pour les aliments traditionnels. Des régressions logistiques multinomiales ont été utilisées pour examiner les associations entre les profils alimentaires, les facteurs sociodémographiques et les marqueurs d'insécurité alimentaire (pour dissocier les préférences alimentaires de l'accès aux aliments). RéSULTATS: Quatre profils alimentaires globaux et quatre profils alimentaires spécifiques à la consommation d'aliments traditionnels ont été identifiés en fonction de la fréquence relative des aliments traditionnels et des aliments du marché dans l'alimentation. Les profils étaient en accord avec les connaissances locales de nos partenaires Inuit. Pour les profils alimentaires globaux, les femmes et les adultes âgés de 30 à 49 ans étaient plus susceptibles d'avoir un profil dominé par les aliments du marché, tandis que les hommes et les personnes âgées de 16 à 29 ans et celles de 50 ans et plus avaient plus fréquemment un profil dominé par les aliments traditionnels. En ce qui concerne les profils de consommation d'aliments traditionnels, les Inuit âgés de 16 à 29 ans étaient plus susceptibles d'avoir un profil modéré de consommation d'aliments traditionnels, tandis que les Inuit âgés de 50 ans et plus étaient plus susceptibles d'avoir un profil élevé de consommation d'aliments traditionnels. Un profil bas de consommation d'aliments traditionnels et de marché était associé à une prévalence plus élevée de marqueurs d'insécurité alimentaire. CONCLUSION: Nous avons identifié différents profils alimentaires et ces derniers étaient associés à des caractéristiques socio-démographiques distinctes. Les profils alimentaires mis en lumière dans cette étude concordent avec l'impact du colonialisme sur l'alimentation au Nunavik et aux programmes subséquents de promotion des aliments traditionnels auprès des jeunes Inuit. Ces profils seront utilisés pour une étude plus approfondie du statut nutritionnel, de l'exposition aux contaminants et des issues de santé afin d'identifier des pistes de solutions pour les futurs programmes de santé publique.
Climate change is disproportionally impacting the Circumpolar North, with particular impacts among Indigenous populations. Environmental changes are felt in many aspects of daily life of Northern communities, including both physical and mental health. Thus, health institutions from around the Arctic must meet emerging needs, while the phenomenon remains marginal to their southern counterparts. In this systematic review, we aimed to review current scientific knowledge on the mental health impacts of climate change in Indigenous Peoples across the Circumpolar North. Seven databases were searched. Original peer-reviewed research articles were included if they addressed links between climate change and mental health in Arctic or Subarctic Indigenous Populations. After extraction, data were synthesized using thematic analysis. Of the 26 articles that met inclusion criteria, 16 focused on Canadian Inuit communities and 21 were exclusively qualitative. Being on the land was identified as a central determinant of wellbeing. Immediate impacts of climate change on mental health were felt through restricted mobility and disrupted livelihoods. Effects on mental health were further felt through changes in culture and identity, food insecurity, interpersonal stress and conflicts, and housing problems. Various ways in how communities and individuals are coping with these effects were reported. Understanding climate-related pathways of mental health risks in the Arctic is crucial to better identify vulnerable groups and to foster resilience. Clinicians can play a role in recognizing and providing support for patients affected by these disruptions. Policies sensitive to the climate-mental health relationship must be advocated for.

A multi-stage sampling strategy selected 1387 on-reserve First Nations adults in Ontario. Foods from a 24-hour dietary recall were assigned to the 100 most common food groups for men and women. Nutrients from market foods (MF) and traditional foods (TF) harvested from the wild as well as MF costs were assigned based on the proportions of total grams consumed. Linear programming was performed imposing various constraints to determine whether it was possible to develop diets that included the most popular foods while meeting Institute of Medicine guidelines. Final models were obtained for both sexes with the top 100 food groups consumed while limiting the nutrient-poor foods to no more than the actual observed intake. These models met all nutrient constraints for men but those for dietary fibre, linoleic acid, phosphorus, and potassium were removed for women. MF costs were obtained from community retailers and online resources. A grocery list was then developed and MF were costed for a family of 4. The grocery list underestimated the actual weekly food cost because TF was not included. Contemporary observed diets deviated from healthier historic First Nations diets. A culturally appropriate diet would include more traditional First Nations foods and fewer MF. Novelty: Linear programming is a mathematical approach to evaluating the diets of First Nations. The grocery list is representative of food patterns within Ontario First Nations and can be used as an alternative to the nutritious food basket used for public health food costing.

OBJECTIVE: The current study undertook a systematic scoping review on the drivers and implications of dietary changes among Inuit in the Canadian Arctic. DESIGN: A keyword search of peer-reviewed articles was performed using PubMed, Web of Science, CINAHL, Academic Search Premier, Circumpolar Health Bibliographic Database and High North Research Documents. Eligibility criteria included all full-text articles of any design reporting on research on food consumption, nutrient intake, dietary adequacy, dietary change, food security, nutrition-related chronic diseases or traditional food harvesting and consumption among Inuit populations residing in Canada. Articles reporting on in vivo and in vitro experiments or on health impacts of environmental contaminants were excluded. RESULTS: A total of 162 studies were included. Studies indicated declining country food (CF) consumption in favour of market food (MF). Drivers of this transition include colonial processes, poverty and socio-economic factors, changing food preferences and knowledge, and climate change. Health implications of the dietary transition are complex. Micro-nutrient deficiencies and dietary inadequacy are serious concerns and likely exacerbated by increased consumption of non-nutrient dense MF. Food insecurity, overweight, obesity and related cardiometabolic health outcomes are growing public health concerns. Meanwhile, declining CF consumption is entangled with shifting culture and traditional knowledge, with potential implications for psychological, spiritual, social and cultural health and well-being. CONCLUSIONS: By exploring and synthesising published literature, this review provides insight into the complex factors influencing Inuit diet and health. Findings may be informative for future research, decision-making and intersectoral actions around risk assessment, food policy and innovative community programmes.

Indigenous Peoples in high-income countries experience higher burdens of food insecurity, obesity, and diet-related health conditions compared to national averages. The objective of this systematic scoping review is to synthesize information from the published literature on the methods/approaches, findings, and scope for research and interventions on the retail food sector servicing Indigenous Peoples in high-income countries. A structured literature search in two major international databases yielded 139 relevant peer-reviewed articles from nine countries. Most research was conducted in Oceania and North America, and in rural and remote regions. Several convergent issues were identified across global regions including limited grocery store availability/access, heightened exposure to unhealthy food environments, inadequate market food supplies (i.e., high prices, limited availability, and poor quality), and common underlying structural factors including socio-economic inequality and colonialism. A list of actions that can modify the nature and structure of retailing systems to enhance the availability, accessibility, and quality of healthful foods is identified. While continuing to (re)align research with community priorities, international collaboration may foster enhanced opportunities to strengthen the evidence base for policy and practice and contribute to the amelioration of diet quality and health at the population level.

We examined the feasibility of linear programming (LP) to develop diets that were economical, included traditional (cultural, non-market) foods and met the dietary reference intakes (DRI) in a Canadian Indigenous population. Diet optimisation using LP is a mathematical technique that can develop food-based dietary guidelines for healthy eating in Indigenous populations where food insecurity, availability and cost are important considerations. It is a means of developing nutritionally optimal food combinations that are based on economical and culture-specific foods. Observed food consumption data were derived using 24-h food recalls from the First Nations Food, Nutrition and Environment Study. The LP models were constructed to develop diets meeting DRI, cost and food constraints. Achieving the recommended food intake was not feasible in a model meeting all nutrient requirements. Models that met most nutrient requirements at reduced cost were designed for men and women, separately. In women, it was necessary to increase energy intake to meet most nutrient requirements. Nutrient requirements could not be met for fibre, linoleic and linolenic acids, vitamin D, Ca and K in both sexes, P in women, and Mg and vitamin A in men. Using LP to develop optimal diets for First Nations people, we found simultaneous achievement of all DRI was difficult, suggesting that supplementation might be necessary which goes against recommendations for individuals to meet their nutrient needs through healthy eating patterns. Additionally, to make diets feasible, programmes to reduce market food costs and to support First Nations people in traditional food harvesting are recommended.

BACKGROUND: Traditional food systems are under pressure from various stressors, including climate change which is projected to negatively alter the abundance of marine species harvested by coastal First Nations (FNs) in British Columbia (BC). OBJECTIVE: To model the potential impacts of the climate-related declines in seafood production on the nutritional status of coastal BC FNs. In addition, we projected potential changes in nutrient intakes, under different scenarios of substitution where traditional seafood is replaced with alternative non-traditional foods. METHODS: The study design is a mixed-method approach that combines two datasets: projected scenarios of climate-related change on seafood catch potential for coastal BC FNs and data derived from the cross-sectional First Nations Food, Nutrition, and Environment Study. The consumption of seafood was estimated using a food frequency questionnaire among 356 FNs. The contribution of seafood consumption to protein, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), vitamins (A, B12, D, niacin), and minerals (zinc, selenium and iron) requirements was assessed using Dietary Reference Intakes (DRIs). RESULTS: Traditional seafood consumption provided daily recommendations of EPA+DHA (74-184%) and vitamin B12 (84-152%) and substantial levels of niacin (28-55%), selenium (29-55%), vitamin D (15-30%) and protein (14-30%). Projected climate change was estimated to reduce the intakes of essential nutrients by 21% and 31% under 'strong mitigation' (Representative Concentration Pathway, RCP2.6) and 'business-as-usual' (RCP8.5) climate change scenarios, respectively, by the year 2050 relative to 2000. The hypothetical substitution of seafood with selected alternative non-traditional foods does not provide adequate amounts of nutrients. CONCLUSION: Traditionally-harvested seafood remains fundamental to the contemporary diet and health of coastal BC FNs. Potential dietary shifts aggravated by climate-related declines in seafood consumption may have significant nutritional and health implications for BC FN. Strategies to improve access to seafood harvest potential in coastal communities are needed to ensure nutritional health and overall well-being and to promote food security and food sovereignty in coastal FNs.

BACKGROUND: Caribou (Rangifer tarandus) is the top dietary source of iron and several micronutrients necessary for red blood cell production (erythropoiesis) in the contemporary diet of Inuit adults across Canada. Many caribou populations across the circumpolar north, however, have experienced dramatic declines in recent decades. Restricted access to caribou may negatively impact the nutrition and health of Inuit communities. METHODS: We used data from the Inuit Health Survey, a cross-sectional survey of 2550 Inuit adults in thirty-six communities across northern Canada (conducted in 2007-2008) to examine the relationship between caribou consumption, hemoglobin (Hb), and blood biomarkers of nutrient intake and contaminant exposure. Multivariable linear regression was used to investigate the potential public health impact of a theoretical restriction in caribou consumption, by estimating the response of Hb concentrations (and the attendant change in anemia prevalence), to theoretical changes in caribou consumption (with and without substitution of caribou with other country food meat). RESULTS: Mean (95% CI) daily caribou meat consumption differed by an order of magnitude 4.3 (3.9-4.7), 51.1 (48.5-53.8), and 236.7 (224.7-248.7) grams/day between tertiles of caribou consumption. Mean (95% CI) hemoglobin levels increased from 129.1 (128.1-130.2) g/L to 132.5 (131.3-133.7) g/L between the highest and lowest tertiles of caribou consumption. In multivariable regression analyses, average daily caribou meat consumption was positively associated (P< 0.001) with hemoglobin levels. This relationship translated into approximately 4 g/L hemoglobin increase in participants in the third tertile of caribou consumption. The overall prevalence of anemia observed in the study population was 26.5% (24.5 - 28.3%) and a modelled restriction in caribou consumption (i.e. caribou = 0) increased the overall prevalence of anemia by approximately 6%. The maximum negative effect of caribou restrictions was related to a complete restriction on caribou consumption, coupled with the substitution of caribou with other country food meat (35.4% prevalence). CONCLUSIONS: Given the importance of caribou to Inuit culture, health and wellbeing, and the high price of healthful market foods in remote northern communities, strategies to promote the sustainable harvest of country foods are urgently required to ensure the health and nutrition security of the Inuit, in the context of rapidly changing Arctic environments and ecosystems.
BACKGROUND: It is generally believed that cardiovascular disease (CVD) is rare in the Inuit population because of their traditional marine-based diet, but the evidence is inconsistent. OBJECTIVE: To describe the cardiovascular health profile of Canadian Inuit, including disease prevalence, risk factors, country food consumption, and contaminant exposure, and compare to that of the general Canadian population. METHODS: Cardiovascular outcomes and risk factors were obtained for 2070 Inuit adults aged 20-79 years from the Inuit Health Survey (IHS, 2007-2008) and for 3464 general Canadian adults aged 20-79 years from the Canadian Health Measures Survey, Cycle 1 (CHMS, 2007-2009) and Cycle 3 (2012-2013). Sex- and age-specific (20-39, 40-59, 60-79) estimates are reported. To compare results between the IHS and CHMS, age-standardized estimates were calculated for males and females, using the CHMS as the reference population. RESULTS: Inuit had higher prevalence of heart attack (3.1% vs. 1.8% females), stroke (2.1% vs. 0.8% males and 2.2% vs. 1.0% females), diabetes (14.6% vs. 9.0% elderly females), obesity (35.8% vs. 24.2% females), and hypertension (12.2% vs. 2.5% young males and 7.5% vs. 2.5% young females). However, Inuit had better blood lipid profile (hyperlipidemia: 29.0% vs. 46.5% males and 28.4% vs. 35.2% females). Metals and persistent organic pollutant exposures were higher among the Inuit compared with general Canadians. CONCLUSION: Inuit and the general Canadian population differ in cardiovascular health profiles. Further research is needed to characterize the health transition among Inuit, especially among the youth and female.

This review summarizes aspects of the 2017 Canadian Nutrition Society symposium, "Modelling diets for quality and cost: examples from Inuit and First Nations in Canada". Indigenous peoples in Canada experience a high prevalence of nutrition-related chronic disease because of the poor quality and high cost of their food supply. Since European colonization, they have transitioned from a diet of minimally processed traditional foods (game, fish, and plants) procured using pursuits such as hunting, fishing, gathering, and horticulture to a diet comprised mostly of processed market foods. This nutrition transition is the result of factors such as colonial policies and practices; climate change; environmental degradation; contaminants in traditional foods; and limited availability of, or access to, economical and healthful market foods. Presenters Malek Batal and Laurie Chan characterized the contemporary diets of First Nations and Inuit populations and demonstrated novel methods for modelling more optimal diets using 2 datasets: the First Nations Food, Nutrition, and Environment Study and the Inuit Health Survey. It was demonstrated how the NOVA classification characterized the portion of the diet consisting of processed foods. Dietary components were then manipulated to reduce ultra-processed food and drink intake to increase the Healthy Eating Index score. Linear programming was explained as a way to mathematically design theoretical diets that aim to optimize food cost, nutrition quality, and contaminant level of traditional foods. While diet-modelling methodologies have limitations, they provide a basis for engaging Indigenous peoples and governments to develop nutrition goals and policies anchored in contemporary food realities.

Caribou (Rangifer tarandus) has been fundamental to the diet and culture of Arctic Indigenous Peoples for thousands of years. Although caribou populations observe natural cycles of abundance and scarcity, several caribou herds across the Circumpolar North have experienced dramatic declines in recent decades due to a range of interrelated factors. Broadly, the objectives of this study are to examine food and nutrition security in relation to wildlife population and management status across Inuit Nunangat (the Inuit homeland, consisting of four regions across the Canadian Arctic). Specifically, we: (1) characterize the contribution of caribou to Inuit nutrition across northern Canada and (2) evaluate the population and management status of caribou herds/populations harvested by Inuit. Dietary data were derived from the 2007-2008 Inuit Health Survey, which included dietary information for Inuit adults (n = 2097) residing in thirty-six communities, spanning three regions (the Inuvialuit Settlement Region, Nunavut, and Nunatsiavut) of the Canadian North. Published information regarding the range, abundance, status, and management status of caribou herds/populations was collected through document analysis and was validated through consultation with northern wildlife experts (territorial governments, co-management, and/or Inuit organizations). While caribou contributed modestly to total diet energy (3-11% of intake) across the regions, it was the primary source of iron (14-37%), zinc (18-41%), copper (12-39%), riboflavin (15-39%), and vitamin B12 (27-52%), as well as a top source of protein (13-35%). Restrictions on Inuit subsistence harvest (harvest quotas or bans) are currently enacted on at least six northern caribou herds/populations with potential consequences for country food access for over twenty-five Inuit communities across Canada. A holistic multi-sectorial approach is needed to ensure the sustainability of wildlife populations, while supporting Inuit food and nutrition security in the interim.

BACKGROUND: Inuit have experienced a rapid transition in diet and lifestyle over the past several decades, paralleled by the emergence of chronic diseases such as obesity, diabetes, and hypertension. OBJECTIVE: To identify contemporary dietary patterns among Inuit and investigate their association with cardiovascular disease outcomes. DESIGN: This was an association study in a cross-sectional population health and nutrition survey. PARTICIPANTS: The participants included 1,570 adults (aged ≥18 years) from Nunavut in the International Polar Year Inuit Health Survey 2007-2008 who completed diet/health questionnaires and provided blood samples. MAIN OUTCOME MEASURES: Outcomes measured included the prevalence of coronary heart disease, myocardial infarction, stroke, hyperlipidemia, and hypertension. STATISTICAL ANALYSES PERFORMED: Principal component analysis was used to derive dietary patterns based on the consumption of nine market food groups and four country food groups reported in 24-hour dietary recalls. The associations between cardiovascular outcomes and identified dietary patterns were examined with logistic regression. RESULTS: Three dietary patterns were identified: market food, country food-fat, and country food-fish. The market food diet, characterized by high consumption of market-bought meat, cereals, vegetables, and added oil, was associated with elevated prevalence of coronary heart disease, myocardial infarction, and hypertension (odds ratio [OR] 1.44, 95% CI 0.82 to 2.51; OR 2.27, 95% CI 0.88 to 5.83; and OR 1.36, 95% CI 0.88 to 2.09). The country food-fish diet, characterized by high fish consumption and low sugar and sweets intake, was inversely associated with the prevalence of coronary heart disease, myocardial infarction, stroke, and hyperlipidemia (OR 0.78, 95% CI 0.43 to 1.37; OR 0.46, 95% CI 0.18 to 1.20; OR 0.34, 95% CI 0.07 to 2.13; and OR 0.69, 95% CI 0.39 to 1.22). The country food-fat diet, characterized by high marine mammal and added fat intake, was positively associated with the prevalence of coronary heart disease. CONCLUSIONS: A diet featuring high food variety, high fish intake, and low sugar intake was negatively associated with the prevalence of cardiovascular outcomes among Inuit.

OBJECTIVE: To characterize the major components of the contemporary Inuit diet and identify the primary sources of energy and essential nutrients. DESIGN: Dietary data were derived from the 24 h recall collected by the Inuit Health Survey (IHS) from 2007 to 2008. The population proportion method was used to determine the percentage contribution of each group. Unique food items/preparations (ninety-three country foods and 1591 market foods) were classified into eight country food groups and forty-one market food groups. Nutrient composition of each food item was obtained from the Canadian Nutrient File. SETTING: Thirty-six communities across three Inuit regions of northern Canada. SUBJECTS: A representative sample (n 2095) of non-pregnant Inuit adults (≥18 years), selected through stratified random sampling. RESULTS: Despite their modest contribution to total energy intake (6·4-19·6 %, by region) country foods represented a major source of protein (23-52 %), Fe (28-54 %), niacin (24-52 %) and vitamins D (up to 73 %), B6 (18-55 %) and B12 (50-82 %). By contrast, the three most popular energy-yielding market foods (i.e. sweetened beverages, added sugar and bread) collectively contributed approximately 20 % of total energy, while contributing minimally to most micronutrients. A notable exception was the contribution of these foods to Ca (13-21 %) and vitamins E (17-35 %) and C (as much as 50 %). Solid fruits were consumed by less than 25 % of participants while vegetables were reported by 38-59 % of respondents. CONCLUSIONS: Country foods remain a critical dimension of the contemporary Inuit diet.
