Traditional and market food access in Arctic Canada is affected by economic factors.
OBJECTIVES: This study aimed to evaluate the access that Indigenous women have to traditional and market foods in 44 communities across Arctic Canada. STUDY DESIGN: This secondary data analysis used a cross-sectional survey of 1771 Yukon First Nations, Dene/Métis and Inuit women stratified by age. METHODS: Socio-cultural questionnaires were used to investigate food access and chi-square testing was used to ascertain the distribution of subject responses by age and region. RESULTS: There was considerable regional variation in the ability to afford adequate food, with between 40% and 70% saying they could afford enough food. Similarly, regional variation was reflected in the percentage of the population who could afford, or had access to, hunting or fishing equipment. Up to 50% of the responses indicated inadequate access to fishing and hunting equipment, and up to 46% of participants said they could not afford to go hunting or fishing. CONCLUSIONS: Affordability of market food and accessibility to hunting and fishing in Arctic Canada were major barriers to Indigenous women's food security.

Impact of a diabetes prevention program on body size, physical activity, and diet among Kanien'keha:ka (Mohawk) children 6 to 11 years old: 8-year results from the Kahnawake Schools Diabetes Prevention Project.
OBJECTIVES: Report the 8-year impact on body size, physical activity, and diet of a community-based diabetes prevention program for elementary-school children in a Kanien'keha:ka (Mohawk) community in Canada. METHODS: Follow-up (1994-1996) of subjects in the intervention and comparison community and repeat cross-sectional measurements in the intervention community alone from 1994 to 2002. Measures included triceps and subscapular skinfold thicknesses, body mass index (BMI), weekly number of 15-minute episodes of physical activity, run/walk test times, television watching, and consumption of sugared foods, fatty foods, and fruits and vegetables. RESULTS: The longitudinal data of 1994-1996 showed some early positive effects of the program on skinfold thickness but not on BMI, physical activity, fitness, or diet. Repeat cross-sectional measures from 1994 to 2002 showed increases in skinfold thickness and BMI. Physical activity, fitness, and television watching showed favorable trends from 1994 to 1999 that were not sustained in 2002. Key high-fat and high-sugar foods consumption decreased, as did consumption of fruits and vegetables. CONCLUSIONS: Although early results showed some successes in reducing risk factors for type 2 diabetes, these benefits were not maintained over 8 years.

Estimation of traditional food intake in indigenous communities in Denendeh and the Yukon.
OBJECTIVES: Chronic non-communicable diseases related to excessive or unbalanced dietary intakes are on the rise among some Indigenous populations in Canada. Nutritional problems of Indigenous peoples arise in the transition from a traditional diet to a market diet characterized by highly processed foods with reduced nutrient density. This study aimed at assessing traditional food intake of Indigenous people in 18 communities. STUDY DESIGN: This study was cross-sectional with a sample size of 1,356. METHODS: This study used food frequency and 24-hour recall questionnaires to quantify traditional food intake in 18 communities in the McKenzie basin of the Northwest Territories (Denendeh and the Yukon). RESULTS: Typical daily intakes of groups of traditional food items were generated and intake of an extensive list of traditional food detailed for adult men and women. Per capita intake of traditional food items was also calculated. CONCLUSION: Reliance on traditional food intake is still high in Denendeh, as well as in the Yukon. The detailed description of the traditional food system presented here allows an accurate identification of the contribution of traditional food items to nutrient and contaminant intake by Indigenous people for future studies.

Correlates of diet quality in the Quebec population.
OBJECTIVE: To determine the correlates of a high-fat diet in urban, suburban and rural areas of Quebec, Canada. DESIGN: A secondary analysis of data collected as part of a 5-year multi-factorial, multi-setting, community-intervention project. SETTING: Urban, suburban and rural settings of the province of Quebec, 1997. SUBJECTS: Data were analysed from a sample of 5214 participants (2227 males, 2987 females). A food-frequency questionnaire was completed and a global index of food quality was calculated. Logistic regression was used to identify correlates of a diet high in total fats, saturated fat and cholesterol. RESULTS: In both genders, lower level of education, smoking status, French and English languages compared with other languages spoken at home, and a rural environment were associated with poor diet quality. Having no intention to eat low-fat dairy products more often was associated with a high-fat diet. In men, obesity (body mass index >/=30 kg m(-2)) and absence of reported health problems were correlates of a high-fat diet, while, in women, lower physical activity was a correlate. CONCLUSIONS: Future health interventions in Quebec should target people with low education, smokers and those living in a rural environment. Obese men and sedentary women should have access to specific dietetic resources.

Ecuadorian Andean women's nutrition varies with age and socioeconomic status.
An agricultural project in Highland Ecuador provided a model context to better understand the nutrition of rural women. The adequacy of women's nutrition and the strength of associations with age and socioeconomic status were studied in 104 rural households over four rounds (two seasons) during the 1995-1996 agricultural year using a cross-sectional with repeated-measures design. Women were at high risk for micronutrient deficiencies (calcium, iron, riboflavin, and vitamin B12) due to low intakes of animal products. Two distinct constructs representing socioeconomic status were identified: modern lifestyle and farming wealth. In multivariate models, farming wealth was associated with quality of women's diet (animal protein adjusted for energy, p = 0.01). Diet quality, in turn, was positively associated with anthropometric status (p = 0.02). Women over the age of 50 weighed approximately 3.7 kg less than younger women and consumed less energy (300 kcal) and micronutrients (p < 0.05). Age was positively associated with respiratory morbidity (p = 0.01). These findings, while directly relevant to a specific context, suggest the need for cross-cultural studies to identify the extent of, and factors contributing to, the risk of nutritional inadequacy in postreproductive women in developing countries.

Comparison of the dietary intakes of two different groups of children (grades 4 to 6) before and after the Kahnawake Schools Diabetes Prevention Project.
The diet of Mohawk children (grades 4 through 6) was assessed using 24-hour recalls after 4 years' participation in the Kahnawake Schools Diabetes Prevention Project. Analysis compared mean intakes of energy, fat, and sucrose, and proportions of children consuming each food. No significant difference was found in the mean intake of energy, fat, and sucrose. There was a significant decrease in the frequency of consumption of high-fat foods (P<.05) and fruits (P<.001), and a significant increase in the energy contribution of white sugar (P<.05). Results illustrate the complexity of food choices and suggest that specific nutrition education targets need to reflect newly available food-items.

The contribution of breast milk to toddler diets in western Kenya.
OBJECTIVE: To understand the relative contributions of breast milk and the weaning diet to overall nutrient intake, with a view to designing and implementing appropriate programmes to improve complementary feeding in developing countries. METHODS: Complementary food intake was measured in a sample of 250 toddlers (mean baseline age: 13.9 +/- 2.4 months) using 24-h dietary recall interviews administered once every 3 weeks over a 6-month period. Breast-milk intake over a 24-h period was measured using the test-weighing method in a subsample of 50 children. Regression effects of age and sex on observed milk intakes were estimated and imputed to the whole sample to estimate mean intake over the observation period. Total energy and nutrient intakes were evaluated for adequacy with reference to published estimates of toddler requirements. FINDINGS: Total energy intake (1029 kcal/day) was adequate, with breast milk supplying an average of 328 kcal/day (32%), but vitamin A, riboflavin, calcium, iron and zinc intakes were below current estimates of required intakes. Observed limitations in nutrient intake were consistent with the finding that almost half of the toddlers were stunted. The prevalence of wasting was 6% at baseline and 4% at final assessment. Although food consumption increased when breastfeeding stopped, it could not fully compensate for the fat and vitamin A previously supplied by breast milk. CONCLUSIONS: The nutritional role of mother's milk in the second year is inversely related to the adequacy of the complementary diet. In this study, breast milk was an irreplaceable source of fat and vitamin A. When the weaning diet is inadequate for key nutrients because of low intake or poor bioavailability, breast milk assumes greater nutritional significance in the second year of life but does not guarantee adequate nutrient intakes.

Contribution of Selected Traditional and Market Foods to the Diet of Nunavik Inuit Women.
Food composition data were determined for food consumed by 226 Inuit women in Nunavik, estimating the relative contribution of traditional and market food for energy, protein, lipid, carbohydrate, vitamin A, vitamin D, iron, calcium, magnesium, phosphorus, selenium, zinc, and eicosapentaenoic and docosahexaenoic acids. Traditional Inuit food was an important source of protein, vitamin D, iron, selenium, and phosphorus, as well as the main source of eicosapentaenoic and docosahexaenoic acids. The mean contribution of traditional and market food to energy and nutrients was analyzed according to age groups (18-39 and 40-74). Analysis of Inuit women's nutrient intake showed that the contribution of traditional food was greater in the older group than in the younger group, for whom the contribution of market food was greater. Market food contributed the most to Inuit women's energy intake, while 40% of the intake of several nutrients, including protein, vitamin D, iron, phosphorus, and zinc, was derived from traditional food. Inuit women had low vitamin A and calcium intakes. Traditional food had low calcium and vitamin A concentrations, and the Inuit infrequently consumed market food such as milk, dairy products, and yellow and green vegetables. Thus, even though the present study showed that traditional food was the major source of many nutrients in the Inuit diet, market food was also important for the nutritional status of this population, particularly young women. In promoting safe nutritional habits among the Inuit, dietitians must help them maintain traditional food use, which has provided some health advantages (e.g., a lower incidence of cardiovascular disease); encourage consumption of nutritious market foods; and consider the societal values reflected in the traditional diet.

Food Use and Nutrient Adequacy in Baffin Inuit Children and Adolescents.
In evaluating adequacy of nutrient intake and relative contribution of locally harvested food (i.e., "traditional" food) and imported market food for 164 Baffin Inuit children and adolescents, 604 24-hour recalls were obtained over a one-year period (1987 to 1988). Market food contributed an average of 84% of dietary energy and traditional food, 16%. Total and saturated fat intakes corresponded closely to current recommendations, while sucrose intakes were higher than recommended. Most age and gender categories had a low prevalence of inadequate intakes of iron, zinc, and protein; over 50% of dietary iron and zinc was provided by traditional food. Calcium and vitamin A were obtained largely through market food, and there was a high risk of inadequacy for both nutrients in all age groups. The diets of 16-18-year-old girls were the most often inadequate, due to high consumption of low nutrient-dense food and low consumption of traditional food. Food items rich in vitamin A and calcium should be promoted, and 16-18-year-old girls specifically targeted for education on food choices and health.

Age differences in vitamin A intake among Canadian Inuit.
BACKGROUND: Inuit traditional food provides ample amounts of preformed vitamin A. However, the dietary transition away from traditional food raises concerns regarding dietary adequacy. Vitamin A is an essential nutrient with inadequate and excessive exposures having adverse effects. OBJECTIVE: To evaluate total dietary vitamin A intake for Canadian Inuit from market food and traditional food sources and to evaluate retinol concentrations in liver and blubber. METHODS: Dietary surveys were conducted in 18 communities representing 5 Inuit regions, and traditional food items were evaluated for nutrient content. RESULTS: Among those 15-40 years of age, 68% of men and 60% of women had a dietary vitamin A intake below the estimated average requirement (EAR) for retinol activity equivalents (RAE)/day. Among those over 40 years of age, only 11 % of men and 15% of women had a dietary vitamin A intake below the EAR. Young Inuit men had a relative risk of 6.2 (95% CI= 4.5-8.4), and young Inuit women had a relative risk of 4.0 (95% CI= 3.1-5.0) for dietary inadequacy compared to the older Inuit men and women, respectively. The median retinol content of liver of ringed seal, caribou, and fish were comparable to levels observed in market food liver. Liver was less frequently consumed by those 15-40 years of age than among older Inuit. DISCUSSION: Sub-optimal vitamin A intake is the predominant nutritional concern rather than excessive exposures. Public health education campaigns are needed to improve vitamin A intake among the younger generations of Inuit men and women.
