RESUMO

This study aims to understand how socioeconomic, geographic and cultural factors affect the food security status of Syrian refugee households in Quebec, Canada. Using a mixed methods study design, 49 households were assessed for their food security and socioeconomic status, followed by structured interviews with 35 households and 9 service providers. 52% of refugee households were food insecure, and although not significantly different, food insecurity was higher among privately sponsored refugee households in the Montreal area. Food insecurity appears mainly due to food access issues. Syrian refugees possess agricultural and cooking skills that could be beneficial in promoting community food security.

RESUMO

BACKGROUND: The prenatal, perinatal, postnatal and nutritional (A3PN) support study was a 4-year initiative aimed to reduce maternal mortality in Haiti. A cross-sectional study was developed to collect the baseline data for evaluation purposes of the A3PN. This study aimed to determine the factors contributing to dietary diversity (DD) in Haitian children aged 6-23 months. METHODS: A cross-sectional study during two seasons (the lean season and the harvest season) was carried out in Haiti to assess the DD of children and their mothers using non-quantitative 24-h recalls. Indicators of DD were minimum dietary diversity for children (MDD-C) and minimum dietary diversity for women (MDD-W). Mid-upper arm circumference was measured in women and children, and food security was assessed using the Household Hunger Scale. Focus groups were also conducted to gain a better understanding of the quantitative findings. RESULTS: Only 7.3% of the children included in this study met the MDD-C. Factors associated with MDD-C were the season (odds ratio [OR]: 0.141 [0.039-0.513]), land ownership or rental (OR: 4.603 [1.233-17.188]), maternal education (OR: 0.092 [0.011-0.749]), the mother's responsibility for the main or secondary source of income for the household (OR: 2.883 [1.030-8.069]) and her DD (OR: 5.690 [1.916-16.892]). Focus groups revealed the existence of various food restrictions. CONCLUSIONS: The results indicated that the low prevalence of MDD-C in three regions of study in Haiti is indicative of a serious public health concern that might be further aggravated by local food taboos. They also suggest that to fight against hunger, it is necessary to focus on women's well-being.

RESUMO

OBJECTIVE: To describe the prevalence of food insecurity in First Nations households across Canada while identifying barriers and enablers to traditional food (TF) consumption. METHODS: The First Nations Food, Nutrition and Environment Study is a cross-Canada participatory study of on-reserve First Nations from 2008 to 2018. The Household Food Security Survey Module was used to capture income-related challenges experienced by First Nations households. Households were classified as food secure, or marginally, moderately, or severely food insecure. Barriers and enablers to TF access and use were identified describing the Indigenous experience. RESULTS: Almost half of on-reserve First Nations households were food insecure and the prevalence was higher than that for non-Indigenous households in Canada. On-reserve food insecurity prevalence was higher in western regions of Canada. First Nations households with children experienced greater food insecurity than those without children. More adults experienced severe food insecurity than children. Most adults would like to have more TF in their diet but state that factors such as financial and household constraints, industrial activities, government regulations, climate change, and fear of contamination impede greater access. Food costs were substantially higher in remote First Nations communities, but remoteness was not associated with food security in multivariable analysis. CONCLUSION: Existing systems have been unsuccessful in curbing the food insecurity in First Nations households. Improving food security hinges on achieving Indigenous Food Sovereignty, the key to long-term conservation and stewardship of the land and the co-management of these by Indigenous Peoples. Studies investigating the feasibility of increasing TF from an Indigenous perspective are required.


RéSUMé: OBJECTIFS: Décrire la prévalence de l'insécurité alimentaire chez les ménages des Premières Nations du Canada tout en identifiant les obstacles et les facilitateurs de l'alimentation traditionnelle (AT). MéTHODES: L'étude sur l'alimentation, la nutrition et l'environnement des Premières Nations dans les réserves est une étude participative pancanadienne des ménages des Premières Nations. Le module d'enquête sur la sécurité alimentaire des ménages a été utilisé pour tenir compte des défis liés au revenu qui confrontent les ménages des Premières Nations. Les ménages ont été classés comme étant en sécurité alimentaire ou insécurité alimentaire marginale, modérée ou sévère. Des obstacles et facilitateurs à l'accès et à l'utilisation des AT ont été identifiés pour décrire l'expérience autochtone. RéSULTATS: Près de la moitié des ménages dans les réserves des Premières Nations dans notre étude étaient en situation d'insécurité alimentaire et la prévalence était supérieure aux ménages non-Autochtones du Canada. L'insécurité alimentaire dans les réserves était plus élevée dans les régions de l'Ouest. Les ménages des Premières Nations ayant des enfants ont connu une plus grande insécurité alimentaire que ceux qui n'en ont pas. Plus d'adultes que d'enfants ont connu une insécurité alimentaire sévère. La plupart des adultes aimeraient avoir plus d'AT dans leur alimentation, mais affirment que des facteurs tels que les contraintes financières et domestiques, les activités industrielles, les réglementations gouvernementales, les changements climatiques et la peur de la contamination empêchent un meilleur accès. Les coûts des aliments étaient considérablement plus élevés dans les communautés isolées des Premières Nations, mais l'isolement n'était pas associé à la sécurité alimentaire dans l'analyse multivariée. CONCLUSION: Les systèmes existants ont échoué à freiner l'insécurité alimentaire chez les ménages des Premières Nations. L'amélioration de la sécurité alimentaire dépend de la réalisation de la souveraineté alimentaire autochtone, une clé pour la conservation à long terme des ressources naturelles et pour une gestion partagée de ces ressources par les peuples autochtones. Des études menées dans une perspective autochtone sur la faisabilité d'améliorer l'accès aux AT sont encore nécessaires.

RESUMO

OBJECTIVE: Assess the diet quality of First Nations adults in Canada using percentage energy from traditional foods (TF) and ultra-processed products (UPP), food portions from the 2007 Eating Well with Canada's Food Guide - First Nations, Inuit and Métis (EWCFG-FNIM) and a Healthy Eating Index (HEI). METHODS: Data collection for this participatory research occurred in 92 First Nations reserves across Canada from 2008 to 2016. Percent daily energy intakes were estimated from 24-hour recalls for TF and NOVA food categories. Portions of food groups from the 2007 EWCFG-FNIM were compared to recommendations. A Canadian-adapted HEI was calculated for each participant. RESULTS: The percent energy from TF was 3% for all participants and 18% for consumers. Meat and alternatives were above the EWCFG-FNIM recommendations and all other food groups were below these. HEI was "low" with only older individuals attaining "average" scores. HEI was above "average" in 4 regions. UPP represented 55% of energy, the largest proportion from a NOVA category. CONCLUSION: The diet quality of First Nations adults in Canada is nutritionally poor. The nutrition, food security and health of First Nations would be improved by better access to TF and healthy store-bought food. However, poor diet is only one aspect of the difficulties facing First Nations in Canada. Researchers and policy makers must strive to better understand the multiple challenges facing First Nations Peoples in order to foster empowerment and self-determination to develop First Nations living conditions and lifestyles that are more culturally sound and more conducive to health.


RéSUMé: OBJECTIFS: Évaluer la qualité de l'alimentation des adultes des Premières Nations du Canada en calculant l'énergie provenant des aliments traditionnels (AT) et des produits ultra-transformés, en comparant les portions consommées avec celles recommandées dans Bien manger avec le Guide alimentaire canadien Premières Nations, Inuit et Métis (BMGAC-PNIM) de 2007 et en mesurant l'indice d'alimentation saine. MéTHODE: La collecte de données pour cette recherche participative a eu lieu dans 92 réserves des Premières Nations au Canada entre les années 2008 et 2016. À partir des rappels de 24 heures, la proportion d'énergie provenant des AT pour les individus les ayant consommés ou non a été comparée, les portions des catégories d'aliments proposées par le BMGAC-PNIM ont été comparées aux recommandations, l'indice d'alimentation saine adapté pour le Canada a été calculé pour chaque participant et la proportion d'énergie des produits ultra-transformés a été établie. RéSULTATS: La proportion d'énergie provenant des AT chez les consommateurs et non-consommateurs était de 3 % et celle pour les consommateurs d'AT était de 18 %. Seuls les viandes et substituts dépassaient les recommandations du BMGAC-PNIM tandis que la consommation de toutes les autres catégories était inférieure aux recommandations. L'indice d'alimentation saine était "bas" avec seulement les individus plus âgés atteignant un score "moyen". L'indice d'alimentation saine était supérieur à "moyen" dans 4 régions. Les aliments ultra-transformés représentaient 55 % de l'énergie, la plus grande proportion de toutes les catégories NOVA. CONCLUSION: La qualité de l'alimentation des Premières Nations n'est pas optimale. Leur alimentation pourrait être améliorée avec un meilleur accès aux AT et aux aliments sains provenant du marché. Une mauvaise alimentation n'est toutefois pas la seule difficulté à laquelle font face les Premières Nations du Canada. Les Peuples des Premières Nations doivent être impliquées avec les chercheurs et les responsables politiques pour mieux comprendre les défis multiples auxquels ils font face et instaurer des conditions de vie qui soient culturellement sécuritaires et plus propices à la santé.

RESUMO

OBJECTIVE: To further understandings of household food insecurity in First Nations communities in Canada and its relationship with obesity. DESIGN: Analysis of a cross-sectional dataset from the First Nations Food, Nutrition and Environment Study representative of First Nations communities south of the 60th parallel. Multivariate logistic regression was used to assess associations between food insecurity and sociodemographic factors, as well as the odds of obesity among food-insecure households adjusting for sociodemographic characteristics. SETTING: Western and Central Canada. PARTICIPANTS: First Nations peoples aged ≥19 years. RESULTS: Forty-six percent of First Nations households experienced food insecurity. Food insecurity was highest for respondents who received social assistance; had ≤10 years of education; were female; had children in the household; were 19-30 years old; resided in Alberta; and had no year-round road access into the community. Rates of obesity were highest for respondents residing in marginally food-insecure households (female 56·6 %; male 54·6 %). In gender-specific analyses, the odds of obesity were highest among marginally food-insecure households in comparison with food-secure households, for both female (OR 1·57) and male (OR 1·57) respondents, adjusting for sociodemographic variables. For males only, those in severely food-insecure (compared with food-secure) households had lower odds of obesity after adjusting for confounding (OR 0·56). CONCLUSIONS: The interrelated challenges of food insecurity and obesity in First Nations communities emphasise the need for Indigenous-led, culturally appropriate and food sovereign approaches to food security and nutrition in support of holistic wellness and prevention of chronic disease.

RESUMO

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.

RESUMO

The Nutrition-Friendly School Initiative was developed in 2006 to counter the double burden of malnutrition and implemented on a pilot basis in primary schools in Ouagadougou (Burkina Faso) in 2009. A baseline study was conducted in intervention and control schools and repeated in 2014 to assess the impact. This paper reports on anthropometric and biochemical data in the final and baseline surveys. Both studies were conducted in the fifth grade classes of the same primary schools in Ouagadougou. Six intervention schools had been selected and matched at baseline with six control schools. The total sample consisted of 699 and 651 pupils in 2009 and 2014, respectively. Anthropometric and hemoglobin measurements were performed on all children, whereas serum retinol was measured in a random subsample to assess Vitamin A Deficiency (VAD). Independent t-tests and chi-squared tests were used for comparison of means and proportions, respectively, and multiple logistic regressions were conducted to examine associations between nutritional parameters and school characteristics. Final rates of anaemia and VAD were 32.6% and 26.1%, respectively, down from 40.4% and 38.7% at baseline. The final prevalence rate of stunting was 8.1%, thinness was 8.7% and overweight/obesity was 4.4%. Thinness declined significantly in 2014 compared to 2009, but there was no change in the rate of stunting even though the rate of overweight/obesity showed an upward trend. When comparing intervention with control schoolchildren, the only significant differences found in the final survey were less thinness and less anaemia in the intervention children. However, the prevalence of anaemia was also significantly lower in the intervention group at baseline. Our results point to a significant improvement in the nutritional status of schoolchildren in Ouagadougou and suggest a positive, although modest, role for the Nutrition-Friendly School Initiative in reducing thinness, but not overweight.

RESUMO

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.

RESUMO

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.

RESUMO

The Eeyouch are a First Nations (Cree) population that live above 49.6°N latitude in Eeyou Istchee in northern Quebec. Eeyouch rely on traditional foods (TF) hunted, fished or gathered from the land. The overarching aim of this study was to achieve an understanding of the factors associated with TF intake among Eeyouch. Data were from 465 women and 330 men who participated in the Nituuchischaayihtitaau Aschii Multi-Community Environment-and-Health (E&H) study. The relationship between TF consumption and dietary, health, sociodemographic and food sovereignty (i.e. being a hunter or receiving Income Security to hunt, trap or fish) variables was examined using linear and logistic regression. Analyses were stratified by sex because of the male/female discrepancy in being a hunter. Among respondents, almost all (99.7%) consumed TF, 51% were hunters and 10% received Income Security. Higher intake of TF was associated with lower consumption of less nutritious ultra-processed products (UPP). In women, TF intake increased with age, hunting and receiving Income Security, but decreased with high school education. In men, TF intake increased with age and speaking only Cree at home. The findings suggest that increased food sovereignty would result in improved diet quality among Eeyouch through increased TF intake and decreased UPP intake.

RESUMO

The study explores the dietary acculturation process among first-generation immigrant families from sub-Saharan Africa or the Caribbean living in Ottawa (Canada). In-depth qualitative interviews were conducted with 12 mothers. The interaction between accelerating factors and other mediating factors resulted in a spiral of dietary changes triggered by immigration. The spiral evolved at different paces from traditional to acculturated and toward healthy or unhealthy diets and was hard to stop or to change in its direction once it started. Findings call for enhancing immigrant mothers' food access, food literacy and nutrition-related parenting skills, and their children's school food environment.

RESUMO

Indigenous peoples have elevated risk of lead (Pb) exposure as hunted traditional food can be contaminated with lead-containing ammunition. Recent scientific consensus states that there is no threshold level for Pb exposure. The objective of this study was to estimate dietary exposure to Pb among First Nations living on-reserve in the province of Ontario, Canada. A total diet study was constructed based on a 24-h recall and Pb concentrations for traditional foods from the First Nations Food, Nutrition, and Environment Study (FNFNES) and Pb concentrations in market foods from Health Canada. A probabilistic assessment of annual and seasonal traditional food consumption was conducted. Results indicate that traditional foods, particularly moose and deer meat. are the primary source of dietary Pb intake (73%), despite providing only 1.8% of the average caloric intake. The average dietary Pb exposure (0.21µg/kg/d) in the First Nations population in Ontario was 1.7 times higher than the dietary Pb exposure in the general Canadian population. Pb intake was associated with an estimated average increase in systolic blood pressure of 1.2mmHg. These results indicate that consumption of foods hunted with Pb containing ammunition and shot puts the population at elevated risk of Pb toxicity.

RESUMO

OBJECTIVE: To quantify associations of the dietary share of ultra-processed foods (UPF) with the overall diet quality of First Nations peoples. DESIGN: A cross-sectional analysis of data from the First Nations Food, Nutrition and Environment Study, designed to contribute to knowledge gaps regarding the diet of First Nations peoples living on-reserve, south of the 60th parallel. A multistage sampling of communities was conducted. All foods from 24 h dietary recalls were categorized into NOVA categories and analyses were performed to evaluate the impact of UPF on diet quality. SETTING: Western and Central Canada. SUBJECTS: First Nations participants aged 19 years or older. RESULTS: The sample consisted of 3700 participants. UPF contributed 53·9 % of energy. Compared with the non-UPF fraction of the diet, the UPF fraction had 3·5 times less vitamin A, 2·4 times less K, 2·2 times less protein, 2·3 times more free sugars and 1·8 times more Na. As the contribution of UPF to energy increased so did the overall intakes of energy, carbohydrate, free sugar, saturated fat, Na, Ca and vitamin C, and Na:K; while protein, fibre, K, Fe and vitamin A decreased. Diets of individuals who ate traditional First Nations food (e.g. wild plants and game animals) on the day of the recall were lower in UPF. CONCLUSIONS: UPF were prevalent in First Nations diets. Efforts to curb UPF consumption and increase intake of traditional First Nations foods and other fresh or minimally processed foods would improve diet quality and health in First Nations peoples.

RESUMO

Methyl Mercury (MeHg) exposure is a global environmental health concern. Indigenous peoples around the world are susceptible to MeHg exposure from often higher fish consumption compared to general populations. The objective of this study was to estimate dietary exposure to methylmercury (MeHg) among First Nations living on-reserve in the province of Ontario, Canada. A total diet study was constructed based on a 24-h recall from the First Nations Food, Nutrition, and Environment Study (FNFNES), and measured contaminant concentrations from Health Canada for market foods, and FNFNES for traditional foods. A probabilistic assessment of annual and seasonal traditional food consumptions was conducted for 1429 adult participants. Results were compared to exposures in the general Canadian population and reference values from Health Canada for adults and women of childbearing age (ages 19-50). Results indicated traditional foods to be the primary contributor to the dietary total MeHg intake (72%). The average dietary total MeHg exposure in the First Nations population in Ontario (0.039µg/kg/d) was 1.6 times higher than the general Canadian population; however, the majority (97.8%) of the population was below the reference values. Mercury concentrations in participants' hair samples (n = 744) ranged from 0.03 to 13.54µg/g, with an average of 0.64µg/g (geometric average of 0.27µg/g). Less than 1% of the population had a hair mercury value above the 6µg/g level, and 1.3% of women of child bearing age had values greater than 2µg/g. Fish species contributing to the MeHg intake included pickerel-walleye, pike, perch and trout. Only 7.9% of the population met the recommended fish consumption rate of two, 3.5oz servings per week from the American Heart Association. Therefore, consumption of lower trophic level fish can be promoted to provide the maximum nutritional benefit with minimal risk of MeHg exposure.

RESUMO

There is a need to identify barriers to participation as well as recruitment strategies to engage minority parents of young children in health-oriented research. This paper offers insights on strategies and challenges in recruiting black immigrant mothers living in Ottawa (Canada) for a community-based health-oriented research project among 6-to-12-year-old children. We recruited 259 mother-child dyads. Most participants were recruited by team members during community events, fairs, religious gatherings, etc. Other successful strategies included referral from participants, community partners, and through research team members' networks. Mass media strategies were mostly ineffective. Instant and meaningful incentives, developing community partnerships, building and ensuring study legitimacy and trust, placing convenience of participants ahead of that of research team members, doing community outreach, and taking contact information on the spot, as well as using word-of-mouth were essential to recruiting. This study clearly indicates the importance of adopting multiple recruitment strategies.

RESUMO

BACKGROUND: Undernutrition contributes to five million deaths of children under five each year. Furthermore, throughout the life cycle, undernutrition contributes to increased risk of infection, poor cognitive functioning, chronic disease, and mortality. It is thus important for decision-makers to have evidence about the effectiveness of nutrition interventions for young children. OBJECTIVES: Primary objective1. To assess the effectiveness of supplementary feeding interventions, alone or with co-intervention, for improving the physical and psychosocial health of disadvantaged children aged three months to five years.Secondary objectives1. To assess the potential of such programmes to reduce socio-economic inequalities in undernutrition.2. To evaluate implementation and to understand how this may impact on outcomes.3. To determine whether there are any adverse effects of supplementary feeding. SEARCH METHODS: We searched CENTRAL, Ovid MEDLINE, PsycINFO, and seven other databases for all available years up to January 2014. We also searched ClinicalTrials.gov and several sources of grey literature. In addition, we searched the reference lists of relevant articles and reviews, and asked experts in the area about ongoing and unpublished trials. SELECTION CRITERIA: Randomised controlled trials (RCTs), cluster-RCTs, controlled clinical trials (CCTs), controlled before-and-after studies (CBAs), and interrupted time series (ITS) that provided supplementary food (with or without co-intervention) to children aged three months to five years, from all countries. Adjunctive treatments, such as nutrition education, were allowed. Controls had to be untreated. DATA COLLECTION AND ANALYSIS: Two or more review authors independently reviewed searches, selected studies for inclusion or exclusion, extracted data, and assessed risk of bias. We conducted meta-analyses for continuous data using the mean difference (MD) or the standardised mean difference (SMD) with a 95% confidence interval (CI), correcting for clustering if necessary. We analysed studies from low- and middle-income countries and from high-income countries separately, and RCTs separately from CBAs. We conducted a process evaluation to understand which factors impact on effectiveness. MAIN RESULTS: We included 32 studies (21 RCTs and 11 CBAs); 26 of these (16 RCTs and 10 CBAs) were in meta-analyses. More than 50% of the RCTs were judged to have low risk of bias for random selection and incomplete outcome assessment. We judged most RCTS to be unclear for allocation concealment, blinding of outcome assessment, and selective outcome reporting. Because children and parents knew that they were given food, we judged blinding of participants and personnel to be at high risk for all studies.Growth. Supplementary feeding had positive effects on growth in low- and middle-income countries. Meta-analysis of the RCTs showed that supplemented children gained an average of 0.12 kg more than controls over six months (95% confidence interval (CI) 0.05 to 0.18, 9 trials, 1057 participants, moderate quality evidence). In the CBAs, the effect was similar; 0.24 kg over a year (95% CI 0.09 to 0.39, 1784 participants, very low quality evidence). In high-income countries, one RCT found no difference in weight, but in a CBA with 116 Aboriginal children in Australia, the effect on weight was 0.95 kg (95% CI 0.58 to 1.33). For height, meta-analysis of nine RCTs revealed that supplemented children grew an average of 0.27 cm more over six months than those who were not supplemented (95% CI 0.07 to 0.48, 1463 participants, moderate quality evidence). Meta-analysis of seven CBAs showed no evidence of an effect (mean difference (MD) 0.52 cm, 95% CI -0.07 to 1.10, 7 trials, 1782 participants, very low quality evidence). Meta-analyses of the RCTs demonstrated benefits for weight-for-age z-scores (WAZ) (MD 0.15, 95% CI 0.05 to 0.24, 8 trials, 1565 participants, moderate quality evidence), and height-for-age z-scores (HAZ) (MD 0.15, 95% CI 0.06 to 0.24, 9 trials, 4638 participants, moderate quality evidence), but not for weight-for-height z-scores MD 0.10 (95% CI -0.02 to 0.22, 7 trials, 4176 participants, moderate quality evidence). Meta-analyses of the CBAs showed no effects on WAZ, HAZ, or WHZ (very low quality evidence). We found moderate positive effects for haemoglobin (SMD 0.49, 95% CI 0.07 to 0.91, 5 trials, 300 participants) in a meta-analysis of the RCTs.Psychosocial outcomes. Eight RCTs in low- and middle-income countries assessed psychosocial outcomes. Our meta-analysis of two studies showed moderate positive effects of feeding on psychomotor development (SMD 0.41, 95% CI 0.10 to 0.72, 178 participants). The evidence of effects on cognitive development was sparse and mixed.We found evidence of substantial leakage. When feeding was given at home, children benefited from only 36% of the energy in the supplement. However, when the supplementary food was given in day cares or feeding centres, there was less leakage; children took in 85% of the energy provided in the supplement. Supplementary food was generally more effective for younger children (less than two years of age) and for those who were poorer/ less well-nourished. Results for sex were equivocal. Our results also suggested that feeding programmes which were given in day-care/feeding centres and those which provided a moderate-to-high proportion of the recommended daily intake (% RDI) for energy were more effective. AUTHORS' CONCLUSIONS: Feeding programmes for young children in low- and middle-income countries can work, but good implementation is key.

RESUMO

BACKGROUND: Little is understood about the economic factors that have influenced the nutrition transition from traditional to store-bought foods that are typically high in fat and sugar amongst people living in the Canadian Arctic. This study aims to determine the pattern of household food expenditure in the Canadian Arctic. METHOD: Local food prices were collected over 12 months in six communities in Nunavut and the Northwest Territories. Dietary intake data were collected from 441 adults using a validated quantitative food frequency questionnaire. Money spent on six food groups was calculated along with the cost of energy and selected nutrients per person. RESULTS: Participants spent approximately 10% of total food expenditure on each of the food groups of fruit/vegetables, grains and potatoes, and dairy, 17% on traditional meats (e.g. caribou, goose, char, and seal liver), and 20% on non-traditional meats (e.g. beef, pork, chicken, fish, and processed meats). Non-nutrient-dense foods (NNDF) accounted for 34% of food expenditure. Younger participants (<30 years) spent more on NNDF and less on traditional meats compared with the older age groups. Participants with higher levels of formal education spent more on fruit and vegetables and less on traditional meats, when compared with participants with lower levels of formal education. CONCLUSIONS: Participants spent most household income on NNDF, a possible consequence of generation discrepancy between younger and older participants. The tendency toward NNDF, particularly among youth, should be addressed with an assessment of predictive factors and the development of targeted approaches to population-based interventions.

RESUMO

PURPOSE: A classification of foods based on the nature, extent, and purpose of industrial food processing was used to assess changes in household food expenditures and dietary energy availability between 1938 and 2011 in Canada. METHODS: Food acquisitions from six household food budget surveys (1938/1939 , 1953, 1969, 1984, 2001, and 2011) were classified into unprocessed or minimally processed foods, processed culinary ingredients, and ready-to-consume processed or ultra-processed products. Contributions of each group to household food expenditures, and to dietary energy availability (kcal per capita) were calculated. RESULTS: During the period studied, household expenditures and dietary energy availability fell for both unprocessed or minimally processed foods and culinary ingredients, and rose for ready-to-consume products. The caloric share of foods fell from 34.3% to 25.6% and from 37% to 12.7% for culinary ingredients. The share of ready-to-consume products rose from 28.7% to 61.7%, and the increase was especially noteworthy for those that were ultra-processed. CONCLUSIONS: The most important factor that has driven changes in Canadian dietary patterns between 1938 and 2011 is the replacement of unprocessed or minimally processed foods and culinary ingredients used in the preparation of dishes and meals; these have been displaced by ready-to-consume ultra-processed products. Nutrition research and practice should incorporate information about food processing into dietary assessments.

RESUMO

Although recent immigrants to Canada are healthier than Canadian born (i.e., the Healthy Immigrant Effect), they experience a deterioration in their health status which is partly due to transitions in dietary habits. Since pathways to these transitions are under-documented, this scoping review aims to identify knowledge gaps and research priorities related to immigrant nutritional health. A total of 49 articles were retrieved and reviewed using electronic databases and a stakeholder consultation was undertaken to consolidate findings. Overall, research tends to confirm the Healthy Immigrant Effect and suggests that significant knowledge gaps in nutritional health persist, thereby creating a barrier to the advancement of health promotion and the achievement of maximum health equity. Five research priorities were identified including (1) risks and benefits associated with traditional/ethnic foods; (2) access and outreach to immigrants; (3) mechanisms and coping strategies for food security; (4) mechanisms of food choice in immigrant families; and (5) health promotion strategies that work for immigrant populations.
