RESUMEN

Worry is influenced by environmental pollution and affects individual health and well-being; however, little is known about this association in Indigenous communities. Using logistic regression models, we examined self-reported responses among Cree adults to the question "Are you worried about the pollution of the environment (land, water or air) in Iiyiyiu Aschii?" to assess if increased worry was associated with proximity to industrial and hydroelectric development, whether increased worry was associated with self-reported behavioural changes of water consumption type in the community or bush, and days spent on-the-land. Proximity to multiple industrial and hydroelectric development sites was associated with increased worry about pollution. Notably, the decreased consumption of tap water in the community was significantly associated with increased worry, but time-on-the land was not. Overall, our study provides new findings concerning development in a Cree territory in northern Quebec, Canada, and the worry about pollution's association with self-reported behavioural changes.

RESUMEN

BACKGROUND: Obesity incidence and prevalence is of increasing concern in First Nations communities around Canada. In addition to diet and physical activity, environmental pollutants have been suggested as a potential contributory factor to obesity associated morbidity. Owing to the exposure of Cree First Nations people to various persistent organic pollutants (POPs) and toxic metals, it is important to examine the association between obesity in these communities, and contaminant body burdens. OBJECTIVE: To determine whether selected morphometry measures (body mass index [BMI], waist circumference [WC] and body fat percentage) are associated with body burdens of 10 POPs and toxic metals. METHODS: Using data from the Nituuchischaayihtitaau Aschii Multi-community Environment-and-Health study in the eastern James Bay (Eeyou Istchee) Cree communities, this cross-sectional study examined morphometric and contaminant measures of 695 eligible participants. Sex stratified principal component analysis was conducted on blood plasma concentrations of 10 POPs and toxic metals. BMI, WC, body fat percent, and resultant contaminant components were used to create generalized linear models, and adjusted for covariates (age, total lipids, smoking, and n-3 fatty acids). RESULTS: Two principal components (PCs; PC-1 and PC-2) were extracted for both males and females. For females, PC-1 explained 73.3% and PC-2 explained 10.5%, and for males, PC-1 explained 71.6% and PC-2 explained 11.2% of the variance in contaminant burden. For both sexes, PC-1 loaded highly for polychlorinated biphenyl (PCB) congeners, organochlorine pesticides and, to a lesser extent, mercury and lead. PC-2 loaded highly for cadmium for females, and cadmium and lead for males. After adjusting for covariates, the generalized linear model showed that PC-2 was significantly and negatively associated with BMI, body fat percent, and WC in males and females. CONCLUSIONS: Our cross-sectional analysis indicates a negative association between cadmium with various obesity measures in both males and females. Null associations were found between PCBs and organochlorine pesticides and morphometry.

RESUMEN

BACKGROUND: Participation in on-the-land programs that encourage traditional cultural activities may improve health and well-being. The Income Security Program (ISP) - a financial incentive-based on-the-land program - for Eeyouch (Cree) hunters and trappers in Eeyou Istchee was created as a result of the 1975 James Bay and Northern Quebec Agreement to help mitigate the effects of hydroelectric development on the Cree people of northern Quebec, Canada. Beyond the ISP's financial incentives, little is known about the health measures of those who are eligible to participate in the ISP (i.e. spent ≥120 days on-the-land during the previous year). Therefore, this paper's objective was to assess the health measures of northern Quebec Cree, who were eligible for participation in the ISP. METHODS: Using participant data (n = 545) compiled from the Nituuchischaayihtitaau Aschii Multi-Community Environment-and-Health Study, we assessed 13 different health measures in generalized linear models with the independent variable being the eligibility to participate in the ISP. RESULTS: Participants in the present study who were eligible for the ISP had significantly higher levels of vigorous and moderate activity per week, and higher concentrations of omega-3 polyunsaturated fatty acids in the blood compared to those ineligible for the ISP (i.e. spent ≤119 days on-the-land during the previous year). Encouragingly, following model adjustment for age and sex, participants eligible for the ISP did not have higher blood concentrations of mercury than those who were not eligible for the ISP. CONCLUSIONS: Our results suggest that the participants eligible for participation in the ISP are likely to be healthier than those who are ineligible to participate - and are promising for on-the-land programs for Indigenous peoples beyond a financial incentive - with no apparent higher risk of increasing contaminant body burden through traditional on-the-land-activities (e.g. fish consumption).

RESUMEN

Exposure to methylmercury is a concern for those who rely on fish as a traditional food in the Eeyou Istchee territory of James Bay, Quebec, Canada, because industrial land uses overlap with community water bodies where fish are harvested. Consequently, this study assessed if traditional practices, particularly fishing, increased the risk of exposure to methylmercury from the consumption of locally harvested fish. We designed a geographic information system (GIS) that included land use and fish methylmercury tissue concentrations to assess clustering of potential hot spots. We also used generalized linear models to assess the association of fish consumption to blood organic-mercury concentrations, and logistic regression models to assess the probability of fish exceeding the safety threshold for methylmercury tissue concentrations in areas of high intensity land use. The GIS demonstrated significant clustered hot spots around regions of hydroelectric and mining land use. Our results also revealed that adult consumption of pike, lake trout and/or walleye, and child consumption of pike or walleye were significantly associated with blood organic-mercury concentrations. Further, large fish harvested in a community with high intensity land use yielded a 77% probability that the fish exceeded the safety threshold. From a human exposure perspective, our study highlights the need for further research on children who consume fish from this region.

RESUMEN

BACKGROUND: The burden of cardiovascular disease (CVD) morbidity and mortality is higher among Indigenous persons, who also experience greater health disparities when compared to non-Indigenous Canadians, particularly in remote regions of Canada. Assessment of carotid intima-media thickness (cIMT), a noninvasive screening tool and can be used as biomarker to assess increased CVD risk. Few studies have examined environmental contaminant body burden and its association with cIMT. METHODS: Data from the Environment-and-Health Study in the Eeyou Istchee territory of northern Québec, Canada was used to assess complex body burden mixtures of POPs, metals and metalloids among (n = 535) Indigenous people between 15 and 87 years of age with cIMT. First, Principal Component Analysis (PCA) was used to reduce the complexity of the contaminant data. Second, based on the underlying PCA profiles from the biological data, we examined each of the prominent principal component (PC) axes on cIMT using multivariable linear regression models. Lastly, based on these PC axes, cIMT was also regressed on summed (Σ) organic compound concentrations, polychlorinated biphenyl, perfluorinated compounds, respectively, ∑10 OCs, ∑13 PCBs, ∑3PFCs, and nickel. RESULTS: Most organochlorines and PFCs loaded primarily on PC-1 (53% variation). Nickel, selenium, and cadmium were found to load on PC-5. Carotid-IMT was significantly associated with PC-1 ß = 0.004 (95 % CI 0.001, 0.007), and PC-5 ß = 0.013 (95 % CI 0.002, 0.023). However, the association appears to be greater for PC-5, accounting for 3% of the variation, and mostly represented by nickel. Results show that that both nickel, and ∑3PFCs were similarly associated with cIMT ß = 0.001 (95 % CI 0.0003, 0.003), and ß = 0.001 (95 % CI 0.0004, 0.002), respectively. But ∑10OCs was significantly associated with a slightly greater ß = 0.004 (95 % CI 0.001, 0.007) cIMT change, though with less precision. Lastly, ∑13PCBs also increased ß = 0.002 (95 % CI 0.0004, 0.003) cIMT after fully adjusting for covariates. CONCLUSION: Our results suggest that environmental contaminants are associated with cIMT. This is important for the Cree from the Eeyou Istchee territory who may experience higher body burdens of contaminants than non-Indigenous Canadians.

RESUMEN

While policies to decrease lead in the environment have been implemented to reduce human exposure to various lead sources, the use of lead ammunition to harvest wild game may continue to contribute significantly to human blood lead levels (BLLs). As part of a multi-community environment-and-health study, BLLs representing all age groups were evaluated in the nine Cree Nations located in the James and Hudson Bay regions of Quebec, Canada. Personal, market food, traditional food and 24-h recall questionnaires were administered. Predictor variables were assessed for various exposure sources, including diet and hunting practices. Elevated BLLs were observed in association with increased hunting status, use of firearms and leaded ammunition, and consumption of traditional foods. Significant differences were observed between all communities, age groups and sexes. Recommendations include educational campaigns that promote switching to non-lead ammunition and, if lead ammunition continues to be used, careful removal from tissues of pellets, bullet fragments and ammunition paths.

RESUMEN

BACKGROUND: The World Health Organization (WHO) recommends a mercury (Hg) hair-to-blood ratio of 250 for the conversion of Hg hair levels to those in whole blood. This encouraged the selection of hair as the preferred analyte because it minimizes collection, storage, and transportation issues. In spite of these advantages, there is concern about inherent uncertainties in the use of this ratio. OBJECTIVES: To evaluate the appropriateness of the WHO ratio, we investigated total hair and total blood Hg concentrations in 1333 individuals from 9 First Nations (Aboriginal) communities in northern Québec, Canada. METHODS: We grouped participants by sex, age, and community and performed a 3-factor (M)ANOVA for total Hg in hair (0-2 cm), total Hg in blood, and their ratio. In addition, we calculated the percent error associated with the use of the WHO ratio in predicting blood Hg concentrations from hair Hg. For group comparisons, Estimated Marginal Means (EMMS) were calculated following ANOVA. RESULTS: At the community level, the error in blood Hg estimated from hair Hg ranged -25% to +24%. Systematic underestimation (-8.4%) occurred for females and overestimation for males (+5.8%). At the individual level, the corresponding error range was -98.7% to 1040%, with observed hair-to-blood ratios spanning 3 to 2845. CONCLUSIONS: The application of the ratio endorsed by the WHO would be unreliable for determining individual follow-up. We propose that Hg exposure be assessed by blood measurements when there are human health concerns, and that the singular use of hair and the hair-to-blood concentration conversion be discouraged in establishing individual risk.

RESUMEN

OBJECTIVE: To measure and describe the prevalence and severity of household food insecurity in a remote on-reserve First Nations community using the Household Food Security Survey Module (HFSSM) and to evaluate the perceived relevance of the HFSSM for this population. DESIGN: Household food security status was determined from the eighteen-item HFSSM following the classifications developed by Health Canada for the Canadian Community Health Survey, Cycle 2·2 Nutrition. One adult from each household in the community was invited to complete the HFSSM and to comment on its relevance as a tool to measure food security for First Nations communities. SETTING: Sub-Arctic Ontario, Canada. SUBJECTS: Households (n 64). RESULTS: Seventy per cent of households were food insecure, 17% severely and 53% moderately. The prevalence of food insecurity in households with children was 76%. Among respondents from homes rated as having severe food insecurity, all (100 %) reported worrying that food would run out, times when food didn't last and there wasn't money to buy more, and times when they couldn't afford to eat balanced meals. The majority of respondents felt the HFSSM did not capture an accurate picture of food security for their situation. Aspects missing from the HFSSM included the high cost of market food and the incorporation of traditional food practices. CONCLUSIONS: A high prevalence of household food insecurity was reported in this community. On-reserve remote First Nations communities may be more susceptible to food insecurity than off-reserve Aboriginal populations. Initiatives that promote food security for this vulnerable population are needed.

RESUMEN

BACKGROUND: There is concern of avian influenza virus (AIV) infections in humans. Subsistence hunters may be a potential risk group for AIV infections as they frequently come into close contact with wild birds and the aquatic habitats of birds while harvesting. This study aimed to examine if knowledge and risk perception of avian influenza influenced the use of protective measures and attitudes about hunting influenza-infected birds among subsistence hunters. METHODS: Using a community-based participatory research approach, a cross-sectional survey was conducted with current subsistence hunters (n = 106) residing in a remote and isolated First Nations community in northern Ontario, Canada from November 10-25, 2013. Simple descriptive statistics, cross-tabulations, and analysis of variance (ANOVA) were used to examine the distributions and relationships between variables. Written responses were deductively analyzed. RESULTS: ANOVA showed that males hunted significantly more birds per year than did females (F1,96 = 12.1; p = 0.001) and that those who hunted significantly more days per year did not perceive a risk of AIV infection (F1,94 = 4.4; p = 0.040). Hunters engaged in bird harvesting practices that could expose them to AIVs, namely by cleaning, plucking, and gutting birds and having direct contact with water. It was reported that 18 (17.0%) hunters wore gloves and 2 (1.9%) hunters wore goggles while processing birds. The majority of hunters washed their hands (n = 105; 99.1%) and sanitized their equipment (n = 69; 65.1%) after processing birds. More than half of the participants reported being aware of avian influenza, while almost one third perceived a risk of AIV infection while harvesting birds. Participants aware of avian influenza were more likely to perceive a risk of AIV infection while harvesting birds. Our results suggest that knowledge positively influenced the use of a recommended protective measure. Regarding attitudes, the frequency of participants who would cease harvesting birds was highest if avian influenza was detected in regional birds (n = 55; 51.9%). CONCLUSIONS: Our study indicated a need for more education about avian influenza and precautionary behaviours that are culturally-appropriate. First Nations subsistence hunters should be considered an avian influenza risk group and have associated special considerations included in future influenza pandemic plans.

RESUMEN

INTRODUCTION: Research investigating the body weight perceptions and eating-related weight control behaviors of First Nations (FN) youth living on reserve in Canada has been scarce. Knowledge of body weight perceptions may help to improve the relevance of initiatives promoting healthy weights. The purpose of this study was to examine the body weight perceptions and eating-related weight control behaviors of grade 6-8 on-reserve FN youth from seven Ontario communities. METHODS: Data were collected from December 2003 to June 2010 from a convenience sample of FN youth (aged 10-14 years) using the Waterloo Web-based Eating Behaviour Questionnaire (WEB-Q). Participants were categorized into body mass index (BMI) categories based on International Obesity Task Force (IOTF) cut points. Frequency statistics were computed in the comparison of measured BMI and weight perceptions and weight control behaviors. Differences by BMI category were tested using Pearson Χ2 tests. RESULTS: A total of 267 youth from seven Ontario FN communities participated in the study (48.6% male). Overall, 36.3% of youth were overweight and 21.3% were obese (combined total of 57.6%). Similar to non-Aboriginal youth, a greater proportion of FN girls who were at a normal weight were concerned that their weight was too high compared to boys. However, one-third of normal weight boys were currently trying to lose weight. A greater proportion of obese girls were trying to lose weight compared to boys. Overall, a large proportion of both overweight boys and girls were attempting to gain weight. CONCLUSIONS: The present study provides a unique investigation into the weight perceptions and weight control behaviors of on-reserve FN youth living in isolated communities in Ontario, Canada. Many of the perceptions elucidated in this study are similar to those observed in non-Aboriginal youth, while others differed. The knowledge of these perceptions and further research to investigate what factors influences them will help to customize health promoting initiatives that are relevant to the youth in the participating communities.

RESUMEN

OBJECTIVE: To assess the adequacy of milk and alternatives, Ca and vitamin D intakes in First Nations (FN) youth in Ontario, Canada. Intakes were compared with the general population and dietary standards. Variation in intakes by community (proxy for remoteness) and BMI was examined. DESIGN: Data were collected by 24 h recall between November 2003 and June 2010. Intakes were analysed descriptively. Variation in intakes, by community and BMI category, was assessed using ANOVA. SETTING: Five remote FN communities of the Mushkegowuk Territory (northern Ontario, Canada) and two less-remote southern Ontario FN communities. SUBJECTS: Schoolchildren (n 457) in grades 6 to 12. RESULTS: Compared with Canada's Food Guide recommendations, 72.6 to 84.7% had an inadequate intake of milk and alternatives depending on age and sex group; 86.2% of individuals fell below the RDA for Ca; 96.4% fell below the RDA for vitamin D. Community variation in intakes was detected, although in all cases Fort Albany had higher intakes, even when it was the more northern (remote) community. A BMI × sex interaction was found for intake of milk and alternatives (P = 0.041): an inverse relationship between intake and BMI was seen in females; in males, those who were overweight had the highest intake, followed by normal-weight and obese youth. CONCLUSIONS: The nutritional inadequacies parallel the results of other Canadian studies of Aboriginal populations. Population health interventions to improve intakes are warranted. Moreover, community variation in intakes exists among FN youth in the present study (Fort Albany pairs only), but results were not as expected.

RESUMEN

BACKGROUND: Food insecurity is a serious public health issue for Aboriginal people (First Nations [FN], Métis, and Inuit) living in Canada. Food security challenges faced by FN people are unique, especially for those living in remote and isolated communities. Conceptualizations of food insecurity by FN people are poorly understood. The purpose of this study was to explore the perceptions of food insecurity by FN adults living in a remote, on-reserve community in northern Ontario known to have a high prevalence of moderate to severe food insecurity. METHODS: A trained community research assistant conducted semi-directed interviews, and one adult from each household in the community was invited to participate. Questions addressed traditional food, coping strategies, and suggestions to improve community food security and were informed by the literature and a community advisory committee. Thematic data analyses were carried out and followed an inductive, data-driven approach. RESULTS: Fifty-one individuals participated, representing 67% of eligible households. The thematic analysis revealed that food sharing, especially with family, was regarded as one of the most significant ways to adapt to food shortages. The majority of participants reported consuming traditional food (wild meats) and suggested that hunting, preserving and storing traditional food has remained very important. However, numerous barriers to traditional food acquisition were mentioned. Other coping strategies included dietary change, rationing and changing food purchasing patterns. In order to improve access to healthy foods, improving income and food affordability, building community capacity and engagement, and community-level initiatives were suggested. CONCLUSIONS: Findings point to the continued importance of traditional food acquisition and food sharing, as well as community solutions for food systems change. These data highlight that traditional and store-bought food are both part of the strategies and solutions participants suggested for coping with food insecurity. Public health policies to improve food security for FN populations are urgently needed.

RESUMEN

INTRODUCTION: In Canada, food insecurity exists among Aboriginal (Inuit, Metis and First Nations) people living in remote northern communities, in part, because of their reliance on the industrialized, import-based food system. Local food production as a substitute to imports would be an adaptive response, but enhancement of food security via food localization requires reflection on previous failings of conventional agricultural strategies so that informed decisions can be made. In light of potential reintroduction of local food production in remote First Nations communities, we investigated the cultural, social and ecological effects of a 20th century, Euro-Canadian agrarian settlement on the food system of a subarctic First Nation; this will act as the first step in developing a more sustainable local food program and enhancing food security in this community. METHODS: To investigate the socio-cultural impacts of the Euro-Canadian agrarian initiative on the food system of Fort Albany First Nation, purposive, semi-directive interviews were conducted with elders and other knowledgeable community members. Interview data were placed into themes using inductive analyses. To determine the biophysical impact of the agrarian initiative, soil samples were taken from one site within the cultivated area and from one site in an undisturbed forest area. Soil properties associated with agricultural use and productivity were assessed. To compare the means of a given soil property between the sites, one-tailed t-tests were employed. Vegetative analysis was conducted in both sites to assess disturbance. RESULTS: According to the interviewees, prior to the agrarian initiative, First Nation families harvested wild game and fish, and gathered berries as well as other forms of vegetation for sustenance. With the introduction of the residential school and agrarian initiative, traditional food practices were deemed inadequate, families were forced to work and live in the settlement (becoming less reliant on traditional foods), and yet little knowledge sharing of agricultural practices occurred. When the residential school and agrarian movement came to an end in the 1970s, First Nation community members were left to become reliant on an import food system. The mission's agrarian techniques resulted in overall degradation of soil quality and ecological integrity: compared the natural boreal forest, the cultivated area had been colonized by invasive species and had significantly lower soil levels of nitrogen, magnesium and organic carbon, and significantly higher levels of phosphorus and bulk density. CONCLUSIONS: Because the agrarian initiative was not a viable long-term approach to food security in Fort Albany, the people became more reliant on imported goods. Taking into account climate change, there exists an opportunity whereby fruits and vegetables, historically stunted-in-growth or outside the distributional range of subarctic Canada, could now grow in the north. Together, agroecosystem stewardship practices and community-based, autonomous food security programs have the potential to increase locally grown food availability in a sustainable manner.

RESUMEN

Hunting, trapping, and fishing are part of an Indigenous lifestyle in subarctic Canada. However, this lifestyle may be a route of exposure to contaminants and may pose a risk for the people who rely on a subsistence diet. Monte Carlo simulations for the chemical concentration of eight game species and one fish species were carried out by randomly sampling 10,000 samples from the contaminant measures for each species. We then calculated a probabilistic non-carcinogenic hazard quotient or carcinogenic risk values to estimate the human health risk of exposure to contaminants. Of the species examined, ducks were of concern for potential carcinogenic risk. There was a modeled probabilistic 95th-percentile risk associated with the consumption of ducks and polybrominated biphenyl (PBB) congener 153 in boys, women, and men (1.09 × 10-6, 1.57 × 10-6, and 2.17 × 10-6, respectively) and, to a lesser extent, with geese and polychlorinated biphenyl (PCB) congener 153 in men (1.19 × 10-6). Contaminant concentration in the intake rate (food consumption) for PBB congener 153 exposure risk was more important than that for PCB congener 153, where intake rate had greater relevance. The consumption of waterfowl may increase the exposure to organohalogens; however, there are health and wellness benefits associated with the harvesting and consumption of subsistence foods that must also be considered. We recommend follow-up species-specific studies focused on ducks to clarify and elucidate the results in the present study.

RESUMEN

Historically, goose harvesting provided a source of culturally significant, safe, and nutritious food for the Omushkego Cree of subarctic Ontario, Canada. Disruptions stemming from colonization and climate change have led to a decrease in harvesting, resulting in higher rates of food insecurity. The aim of the Niska program was to reconnect Elders and youth to revitalize goose harvesting activities and associated Indigenous knowledge within the community. The program and evaluation were built using a two-eyed seeing (Etuaptmumk) and community-based participatory research approach. Salivary cortisol, a biomedical measure of stress, was collected before (n = 13) and after (n = 13) participation in the spring harvest. Likewise, cortisol samples were collected before (n = 12) and after (n = 12) the summer harvest. Photovoice and semi-directed interviews were employed after the spring (n = 13) and summer (n = 12) harvests to identify key elements of well-being from an Indigenous perspective. The changes observed in cortisol levels for the spring (p = 0.782) and summer (p = 0.395) harvests were not statistically significant. However, there was a noteworthy increase in the subjective well-being observed through the qualitative measures (semi-directed interviews and photovoice), highlighting the importance of using multiple perspectives when assessing well-being, especially in Indigenous peoples. Future programs should incorporate multiple perspectives when addressing complex environmental and health issues, such as food security and environmental conservation, especially in Indigenous homelands worldwide.

The Albany River system holds a special significance for the Omushkego Cree of subarctic Ontario, Canada, embodying their cultural roots, history, and the Cree way of life and worldviews. Through the Sibi program, youth learned traditional fishing practices from Elders and on-the-land experts, gaining valuable knowledge on the land and river. The program addressed barriers to being on the land, while also creating a space for the transfer of Indigenous knowledge and revitalising community social networks. The program took place in the summer, following the Omushkego Cree's seasonal cycle and employed community-based participatory research approach. Photovoice and semi-structured interviews were used to identify elements of well-being from an Indigenous perspective. Regardless of age or experience, participants expressed positive emotions while being on the land, highlighting how strengthening social and community networks, intergenerational knowledge transfer, and fostering cultural continuity contribute to improved well-being. Program outcomes emphasize the importance of collaboration with communities to gain insights into their needs, priorities, and values, ultimately creating more sustainable and effective well-being programs. By fostering engagement and recognizing the environment's significance, sustainable and long-term solutions can be pursued to address challenges faced by communities, ultimately advancing health and well-being for both present and future generations.The Albany River system holds a special significance for the Omushkego Cree of subarctic Ontario, Canada, embodying their cultural roots, history, and the Cree way of life and worldviews.

RESUMEN

Indigenous peoples' perceptions of wellbeing differ from non-Indigenous constructs. Thus, it is imperative to recognize that Indigenous peoples will conceptualize wellbeing from their perspectives and set their own wellbeing priorities. In keeping with this viewpoint, the aims of the present study were to conceptualize wellbeing and determine what was (and is) important for wellbeing from Canadian Indigenous peoples' perspectives. In this paper, we take a partnership approach based on the elements of respect, equity, and empowerment. One primary data source and two existing data sources were examined and analyzed thematically utilizing a combination approach of deductive and inductive coding. Indigenous leadership and organizations viewed wellbeing holistically and conceptualized wellbeing multidimensionally. From across Canada, wellbeing was communicated as physical, economic, political, social, and cultural. The scaling of wellbeing represented a collectivist perspective, and land was the connecting thread between all types of wellbeing, being a place to practice cultural traditions, reassert one's Indigenous identity, find solace, and pass on Indigenous knowledge and languages. Although wellbeing was discussed in the context of the individual, family, community, and nation, wellbeing was most often discussed at the cultural level by regional and national Indigenous leadership and organizations. Even in acknowledging the great cultural diversity among Canadian Indigenous nations, four concordant themes were identified regionally and nationally, with respect to what was important for cultural wellbeing: land and water, sustainability, and inherent obligations; being on the land, and indigenous languages and knowledge systems; sustainable development; and meaningful involvement in decision-making, and free, prior, and informed consent. Taking into account these themes is foundational for any interaction with Indigenous peoples, especially in the context of land, culture, and development. There needs to be a new beginning on the journey to reconciliation with land and cultural wellbeing at the forefront.

RESUMEN

BACKGROUND: Public health emergencies have the potential to disproportionately impact disadvantaged populations due to pre-established social and economic inequalities. Internationally, prior to the 2009 H1N1 influenza pandemic, existing pandemic plans were created with limited public consultation; therefore, the unique needs and characteristics of some First Nations communities may not be ethically and adequately addressed. Engaging the public in pandemic planning can provide vital information regarding local values and beliefs that may ultimately lead to increased acceptability, feasibility, and implementation of pandemic plans. Thus, the objective of the present study was to elicit and address First Nations community members' suggested modifications to their community-level pandemic plans after the 2009 H1N1 influenza pandemic. METHODS: The study area included three remote and isolated First Nations communities located in sub-arctic Ontario, Canada. A community-based participatory approach and community engagement process (i.e., semi-directed interviews (n = 13), unstructured interviews (n = 4), and meetings (n = 27)) were employed. Participants were purposively sampled and represented various community stakeholders (e.g., local government, health care, clergy, education, etc.) involved in the community's pandemic response. Collected data were manually transcribed and coded using deductive and inductive thematic analysis. The data subsequently informed the modification of the community-level pandemic plans. RESULTS: The primary modifications incorporated in the community-level pandemic plans involved adding community-specific detail. For example, 'supplies' emerged as an additional category of pandemic preparedness and response, since including details about supplies and resources was important due to the geographical remoteness of the study communities. Furthermore, it was important to add details of how, when, where, and who was responsible for implementing recommendations outlined in the pandemic plans. Additionally, the roles and responsibilities of the involved organizations were further clarified. CONCLUSIONS: Our results illustrate the importance of engaging the public, especially First Nations, in pandemic planning to address local perspectives. The community engagement process used was successful in incorporating community-based input to create up-to-date and culturally-appropriate community-level pandemic plans. Since these pandemic plans are dynamic in nature, we recommend that the plans are continuously updated to address the communities' evolving needs. It is hoped that these modified plans will lead to an improved pandemic response capacity and health outcomes, during the next public health emergency, for these remote and isolated First Nations communities. Furthermore, the suggested modifications presented in this paper may help inform updates to the community-level pandemic plans of other similar communities.

RESUMEN

INTRODUCTION: School snack and breakfast programs may be especially important in remote northern communities where many households are food insecure. Despite the strong potential for school programs to improve the dietary intake and eating behaviours of children and youth, very few studies have reported on the effects of school nutrition programs in Aboriginal communities. The purpose of this study was to examine the impact of a school snack program on the dietary intake of grade six to ten First Nation students living in a remote community in northern Ontario. METHODS: Data were collected in November 2004 and December 2007 with grade six to ten (aged 10-18 years) students (n=63 and n=50, respectively) using a validated web-based 24 hour diet recall survey, the WEB-Q. Food group consumption and nutrient intake of students participating in the school snack program on the previous day were compared with students who chose not to participate. In each year, ANOVA was used to assess differences between participants and non-participants, genders, and grade groups. The second data collection in December of 2007 included five questions asking students about their participation, preferences, and impressions of the snack program. RESULTS: Students participating in the snack program during the 2004 data collection (37%; n=23) compared with those who did not (63%; n=40) had significantly (p<0.05) higher mean intakes from the 'Vegetables and Fruit' food group (7.5 vs 3.4 servings), folate (420 vs 270 µg), dietary fiber (18 vs 8 g), vitamin C (223 vs 94 mg), calcium (1055 vs 719 mg) and iron (16.5 vs 11.7 mg). For the 2007 data collection, snack program participants (52%; n=26) had higher intakes from the 'Milk and Alternatives' food group (3.3 vs 2.2 servings), vitamin A (697 vs 551 RE [retinol equivalents]), calcium (1186 vs 837 mg), and vitamin D (6.9 vs 4.4 µg) and significantly lower intakes of 'Other' foods (6.0 vs 7.2 servings) compared with non-participants (48%; n=24). For 2004 and 2007, differences in intake also occurred by gender and grade groupings, with no interaction effects between snack participation and gender or grade. With the exception of 'Meat and Alternatives' in 2004, there was a trend for a higher percentage of students to meet dietary recommendations if they participated in the snack program. Students indicated that the three things they liked most about the school snack program were the juice (50%), that the program kept them from feeling hungry at school (40%), and that they got a snack at school every day (32%). Students indicated that the snack program helped them to eat healthier by motivating them (74%), eating more fruit (86%), and making better dietary choices (68%). CONCLUSIONS: Given the positive impact of the program on the food and nutrient intake of school snack program participants, qualitative feedback will be used to enhance the program and participation. Clearly, school snack programs can be an important venue to address the nutritional vulnerability of First Nation youth living in remote communities.

RESUMEN

INTRODUCTION: In Canada, unique food security challenges are being faced by Aboriginal people living in remote-northern communities due to the impacts of climate change on subsistence harvesting. This study used traditional environmental knowledge (TEK) to investigate whether there was a temporal relationship between extreme climatic events in the summer of 2005, and fish die-offs in the Albany River, northern Ontario, Canada. Also, TEK was utilized to examine a potential shift in subsistence fish species distribution due to climate change. METHODS: To investigate whether there was a temporal relationship between the fish die-offs of July 2005 (as identified by TEK) and an extreme climatic event, temperature and daily precipitation data for Moosonee weather station were utilized. To determine if there was an increasing trend in mean maximal summer temperatures with year, temperature data were examined, using regression analysis. Present-day fish distributions were determined using unpublished TEK data collated from previous studies and purposive, semi-directive interviews with elders and experienced bushman. RESULTS: Fish die-offs in 2005 occurred during the time period 11-18 July, as reported by participants. Recorded air-temperature maxima of the two July 2005 heat waves delineate exactly the time period of fish die-offs. Two heat waves occurring during the same summer season and so close together has never before been recorded for this region. A highly significant (p < 0.0009) positive relationship between mean maximal summer temperatures and year was evident. Regionally novel fish species were not apparent, utilizing TEK. CONCLUSIONS: Traditional environmental knowledge coupled with climate data revealed temporal relationships between extreme climatic events in 2005, and fish die-offs in the Albany River. Thus, climate change can directly impact food security by decreasing the number of fish through mortality - and indirectly through population dynamics - by impacting the yield of fish subsistence harvests in the future. By contrast, TEK did not reveal northward expansion of novel fish species in the Albany River or fish distributional contraction in the western James Bay region.
