Objective: To compare dietary intake and quality among adult Inuit by smoking status.Design: A cross-sectional study using data from a validated quantitative FFQ.Setting: Three isolated communities in Nunavut, Canada.Subjects: Adult Inuit (n 208), aged between 19 and 79 years, from randomly selected households.Results: Average energy intake did not differ between male smokers (n 22) and non-smokers (n 14; 16 235 kJ and 13 503 kJ; P = 0·18), but was higher among female smokers (n 126) compared with non-smokers (n 46; 12 704 kJ and 8552 kJ; P < 0·0001). Average daily nutrient intakes were similar among men and higher among female smokers compared with non-smokers for all nutrients (P ≤ 0·05) except n-3 fatty acids, vitamin A, vitamin D and Se. Female smokers had lower intake densities of thiamin, niacin, vitamin B6, folate, Mg, Na (P ≤ 0·05), protein, n-3 fatty acids, cholesterol, Fe (P ≤ 0·01), vitamin B12 and Se (P ≤ 0·001). Between 20 % and 50 % of male and female smokers were below the Dietary Reference Intake (DRI) for Ca, folate, Mg and vitamins A and K, and more than 50 % were below the DRI for fibre and vitamin E. The proportion of smokers below the DRI was lower for all nutrients, except fibre and folate among men. Among smokers, non-nutrient-dense foods and traditional foods contributed less to energy (-2·1 % and -2·0 %, respectively).Conclusions: Adult smokers consumed fewer nutrient-dense, traditional foods, but had increased energy intake, which likely contributed to fewer dietary inadequacies compared with non-smokers. Promoting traditional food consumption supplemented with market-bought fruits and vegetables is important to improve dietary quality, especially among smokers. [ABSTRACT FROM AUTHOR]

Dietary transition in the Arctic is associated with decreased quality of diet, which is of particular concern for women of childbearing age due to the potential impact of maternal nutrition status on the next generation. The study assessed dietary intake and adequacy among Inuit women of childbearing age living in three communities in Nunavut, Canada. A culturally-appropriate quantitative food-frequency questionnaire was administered to 106 Inuit women aged 19-44 years. Sources of key foods, energy and nutrient intakes were determined; dietary adequacy was determined by comparing nutrient intakes with recommendations. The prevalence of overweight/obesity was >70%, and many consumed inadequate dietary fibre, folate, calcium, potassium, magnesium, and vitamin A, D, E, and K. Non-nutrient-dense foods were primary sources of fat, carbohydrate and sugar intakes and contributed >30% of energy. Traditional foods accounted for 21% of energy and >50% of protein and iron intakes. Strategies to improve weight status and nutrient intake are needed among Inuit women in this important life stage.

Background: Inuit in Arctic regions are experiencing a rapid diet and lifestyle transition. There are limited data on food consumption patterns among this unique population, raising concerns about assessing the risk for the development of diet-related chronic diseases., Objective: To assess the current frequency of consumption of foods and beverages among Inuit in Nunavut, Arctic Canada., Methods: A cross-sectional dietary study was conducted among randomly selected Inuit adults from three communities in Nunavut using a validated quantitative food frequency questionnaire. The participants were 175 women and 36 men with median (IQR) ages of 41.0 (32.5-48.5) and 40.1 (30.0-50.0) years, respectively. The mean and median frequencies of consumption over a 30-day period were computed for 147 individual food items and grouped as foods or beverages., Results: The 30 most frequently consumed foods were identified. Non-nutrient-dense foods (i.e., high-fat and high-sugar foods) were the most frequently consumed food group (median intake, 3.4 times/day), followed by grains (2.0 times/day) and traditional meats (1.7 times/day). The frequency of consumption of fruits (0.7 times/day) and vegetables (0.4 times/day) was low. The median values for the three most frequently consumed food items were sugar or honey (once/day), butter (0.71 times/day), and Coffee-mate (0.71 times/day). Apart from water, coffee, and tea, the most frequently consumed beverages were sweetened juices (0.71 times/day) and regular pop (soft drinks) (0.36 times/day). This study showed that non-nutrient-dense foods are consumed most frequently in these Inuit communities., Conclusions: The results have implications for dietary quality and provide useful information on current dietary practices to guide nutritional intervention programs.

Diet-related chronic diseases are highly prevalent among indigenous populations in the Canadian Arctic. A community-based, multi-institutional nutritional and lifestyle intervention-Healthy Foods North-was implemented to improve food-related psychosocial factors and behaviors among Inuit and Inuvialuit in four intervention communities (with two comparison communities) in Nunavut and the Northwest Territories, Canada, in 2008. The 12-month program was developed from theory (social cognitive theory and social ecological models), formative research, and a community participatory process. It included an environmental component to increase healthy food availability in local stores and activities consisting of community-wide and point-of-purchase interactive educational taste tests and cooking demonstrations, media (e.g., radio ads, posters, shelf labels), and events held in multiple venues, including recreation centers and schools. The intervention was evaluated using pre- and postassessments with 246 adults from intervention and 133 from comparison communities (311 women, 68 men; mean age 42.4 years; 78.3% retention rate). Outcomes included psychosocial constructs (healthy eating knowledge, self-efficacy, and behavioral intentions), frequency of healthy and unhealthy food acquisition, healthiness of commonly used food preparation methods, and body mass index (kg/m(2)). After adjustment for demographic, socioeconomic status, and body mass index variables, respondents living in intervention communities showed significant improvements in food-related self-efficacy (β = 0.15, p = .003) and intentions (β = 0.16, p = .001) compared with comparison communities. More improvements from the intervention were seen in overweight, obese, and high socioeconomic status respondents. A community-based, multilevel intervention is an effective strategy to improve psychosocial factors for healthy nutritional behavior change to reduce chronic disease in indigenous Arctic populations.
