RESUMEN

Background: Non-government organizations (NGOs) spend substantial time and resources collecting baseline data in order to plan and implement health interventions with marginalized populations. Typically interviews with households, often mothers, take over an hour, placing a burden on the respondents. Meanwhile, estimates of numerous health and social indicators in many countries already exist in publicly available datasets, such as the Demographic and Health Surveys (DHS) and the Multiple Indicator Cluster Surveys (MICS), and it is worth considering whether these could serve as estimates of baseline conditions. The objective of this study was to compare indicator estimates from non-governmental organizations (NGO) health projects' baseline reports with estimates calculated using the Demographic and Health Surveys (DHS) or the Multiple Indicator Cluster Surveys (MICS), matching for location, year, and season of data collection. Methods: We extracted estimates of 129 indicators from 46 NGO baseline reports, 25 DHS datasets and three MICS datasets, generating 1,996 pairs of matched DHS/MICS and NGO indicators. We subtracted NGO from DHS/MICS estimates to yield difference and absolute difference, exploring differences by indicator. We partitioned variance of the differences by geographical level, year, and season using ANOVA. Results: Differences between NGO and DHS/MICS estimates were large for many indicators but 33% fell within 5% of one another. Differences were smaller for indicators with prevalence <15% or >85%. Difference between estimates increased with increasing year and geographical level differences. However, <1% of the variance of the differences was explained by year, geographical level, and season. Conclusions: There are situations where publicly available data could complement NGO baseline survey data, most importantly when the NGO has tolerance for estimates of low or unknown accuracy.

RESUMEN

OBJECTIVE: To describe the traditional food (TF) systems of First Nations in Canada, including intake, barriers and promoters. METHODS: The First Nations Food, Nutrition and Environment Study is a cross-Canada participatory study of First Nations adults below the 60th parallel that obtained data for communities excluded from other national studies. A food frequency questionnaire was used to establish frequency of TF intake (number of days in a year) to allow comparisons across ecozones/regions in Canada. Grams of TF intake were also calculated using frequency multiplied by average portions from 24-h recalls. Closed- and open-ended questions attempted to identify some of the key barriers and concerns regarding TF access and use. Multivariable analyses were run to determine what factors are associated with increased TF consumption. RESULTS: Across communities, there is a strong preference by adults to have TF in the diet more often. Consumption of land animals was most frequently reported in most ecozones except for the Pacific Maritime and Mixedwood Plains, where fish and plants, respectively, were more frequently consumed. First Nations identified structural and environmental challenges such as development, government regulations and climate change, along with household barriers such as insufficient capital for equipment and transportation, lack of time and absence of a hunter in the household. Multivariable analyses revealed that the highest intake of TF occurred in the Taiga Plains ecozone, and for older individuals and men. CONCLUSION: Identifying solutions that empower First Nations at all levels is required to overcome the multiple challenges to the inclusion of TF in the diet.


RéSUMé: OBJECTIFS: Décrire les systèmes alimentaires traditionnels (AT) des adultes provenant des Premières Nations du Canada, y compris la consommation, les barrières et les promoteurs. MéTHODE: L'Étude sur l'alimentation, la nutrition et l'environnement chez les Premières Nations est une étude participative pancanadienne avec les Premières Nations demeurant dans les réserves au sud du 60e parallèle et qui a permis d'obtenir des données sur les communautés exclues d'autres études nationales. Un questionnaire sur la fréquence des aliments fut utilisé pour établir la fréquence de l'apport en AT (nombre de jours par année) afin de permettre des comparaisons entre les ecozones et régions du Canada. Les grammes d'apport en AT furent également calculés en utilisant la fréquence multipliée par les portions moyennes provenant des rappels de 24 heures. Des questions fermées et ouvertes ont tenté d'identifier certains des principaux obstacles et préoccupations concernant l'accès et l'utilisation des AT. Des analyses multivariées furent effectuées pour identifier quels facteurs sont associés à une consommation plus élevée des AT. RéSULTATS: Dans toutes les communautés, les adultes préfèrent avoir un apport plus fréquent des AT. La consommation des animaux terrestres a été mentionnée le plus souvent dans la plupart des écozones, sauf dans les Maritimes Pacifiques et les Plaines Boismixtes, où les poissons et les plantes, respectivement, étaient plus fréquemment consommés. Les Premières Nations ont identifié des défis structurels et environnementaux tels que le développement, la réglementation gouvernementale et les changements climatiques, ainsi que des obstacles pour les ménages comme l'insuffisance de capitaux pour l'équipement et le transport, le manque de temps et l'absence de chasseur dans le ménage. Une analyse multivariée a révélé que la consommation la plus élevée d'AT avait lieu dans l'écozone de la Taïga des Plaines, ainsi que pour les personnes plus âgées et les hommes. CONCLUSION: Il est important d'identifier des solutions qui renforcent le pouvoir des Premières Nations à surmonter les défis multiples qui entravent la consommation des AT.

RESUMEN

OBJECTIVES: To identify food sources of nutrients in First Nations adults in Canada and to establish whether these populations are meeting their nutrient requirements and whether traditional foods (TF) contribute to better nutrient intake. METHODS: The First Nations Food, Nutrition and Environment Study is a cross-Canada participatory study of First Nations adults living south of the 60th parallel. Twenty-four-hour recalls were conducted in 92 First Nations communities from 2008 to 2016. Repeat recalls were attempted with 20% of participants to adjust for within-person variation and estimate the proportion of individuals below recommendations according to Institute of Medicine guidelines. Nutrients from days with and without TF were compared. The main food sources of select nutrients were identified, including TF. RESULTS: Mean energy intakes among women and men ranged from 1664 to 1864 and from 1761 to 2298 kcal/day respectively. Most macronutrients were within the acceptable macronutrient diet range except for fat in most age groups and carbohydrates in men 71 years of age and older. Saturated fat was above recommendations for all ages. Only niacin was identified as above recommendations in all age and sex categories. Days where TF were eaten showed greater intakes of key nutrients. CONCLUSION: It is imperative that we find culturally appropriate ways to improve the quality and nutritional value of First Nations Peoples food intake by improving TF access and use on the one hand and conversely providing better quality store-bought foods. For success in this, we must empower First Nations communities and health practitioners to collaboratively overcome these challenges.


RéSUMé: OBJECTIFS: Établir si l'alimentation des adultes des Premières Nations au Canada est satisfaisante et si les aliments traditionnels (AT) contribuent à un meilleur apport en nutriments et identifier les sources alimentaires des nutriments. MéTHODE: L'étude sur l'alimentation, la nutrition et l'environnement chez les Premières Nations est une étude participative pancanadienne visant les adultes des Premières Nations vivant au sud du 60e parallèle. Des rappels de 24 heures ont été effectués dans 92 communautés des Premières Nations de 2008 à 2016. Les rappels ont été répétés avec 20 % des participants pour ajuster la variation intra-individuelle et estimer la proportion d'individus à risque de consommation insuffisante de nutriments selon les apports nutritionnels de référence de l'« Institute of Medicine ¼. Les sources alimentaires (incluant les AT) de certains nutriments ont été identifiées. RéSULTATS: La moyenne des apports énergétiques moyens chez les femmes et les hommes variaient de 1 664 à 1 864 et 1 761 à 2 298 kilocalories/jour respectivement. La plupart des macronutriments se situaient dans l'intervalle établi par l'étendue des valeurs acceptables des macronutriments, à l'exception des lipides dans la plupart des groupes d'âge et des glucides chez les hommes de 71 ans et plus. Les acides gras saturés étaient supérieurs aux recommandations pour tous les âges. Seule la niacine était supérieure au besoin moyen estimatif. Les jours où les AT sont consommés, une augmentation notable dans les apports en certains nutriments-clés est observée. CONCLUSION: Il est important de trouver des moyens pour améliorer la qualité et la valeur nutritionnelle de l'apport alimentaire des Peuples des Premières Nations en respectant leur culture et en offrant un meilleur accès et une utilisation améliorée des AT d'une part et en fournissant des aliments provenant du magasin de meilleure qualité d'autre part. Pour réussir, les communautés des Premières Nations et les professionnels de la santé devraient être impliqués de manière collaborative.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVE: Our objective is to describe self-reported health status, prevalence of diabetes and obesity and their associations in participants from the First Nations Food, Nutrition and Environment Study (FNFNES) in order to identify possible correlates of health in First Nations adults. METHODS: FNFNES is a participatory study with First Nations Peoples living on reserve lands south of the 60th parallel. Health and diabetes were self-reported, and prevalence of obesity was evaluated. Socio-demographic and lifestyle factors and traditional food (TF) activities were investigated for associations with health parameters. RESULTS: High prevalence rates of overweight/obesity (78-91%) and diabetes (19% age-standardized prevalence) were found. Smoking rates were high and physical activity was low. In multivariable analyses, obesity was associated with region, income source, age, gender, smoking and self-reported health; diabetes and lesser self-reported health were associated with obesity and lower education. Diabetes was strongly associated with lesser self-reported health and weakly associated with being a smoker. CONCLUSION: We have identified possible correlates of health in this population that can help to better understand the underlying concerns and identify solutions for First Nations and their partners. We urge governments and First Nations to address the systemic problems identified with a holistic ecosystem approach that takes into consideration the financial and physical access to food, particularly TF, and the facilitation of improved health behaviour. New mechanisms co-developed with First Nations leadership should focus on supporting sustainable, culturally safe and healthy lifestyles and closing the gaps in nutrition and food insecurity.


RéSUMé: OBJECTIFS: Décrire l'état de santé autodéclaré, les prévalences de diabète et d'obésité et leurs associations chez les participants de l'Étude sur l'alimentation, la nutrition et l'environnement des Premières Nations (EANEPN) afin d'identifier d'éventuelles associations avec la santé chez les adultes des Premières Nations. MéTHODE: L'EANEPN est une étude participative entreprise avec les Peuples des Premières Nations vivant dans les réserves au sud du 60e parallèle. L'état de santé et le diabète ont été autodéclarés et la prévalence de l'obésité a été évaluée. Les facteurs sociodémographiques et de style de vie et les activités d'apports en aliments traditionnels (AT) ont été étudiés pour leurs associations avec les paramètres de santé. RéSULTATS: Une prévalence élevée de surpoids/obésité (78­91%) et de diabète (19% ­ taux normalisé selon l'âge) a été observée. Le taux de tabagisme était élevé et l'activité physique était faible. Dans les analyses multivariées, l'obésité était associée avec la région, la source de revenu, l'âge, le sexe, le tabagisme et l'état de santé autodéclaré; le diabète et l'état de santé faible autodéclarés étaient positivement associés à l'obésité et à moins d'années d'éducation. Le diabète était fortement associé à un faible état de santé autodéclaré et légèrement avec le tabagisme. CONCLUSION: Nous avons identifié des corrélats de santé potentiels dans cette population qui peuvent nous aider à mieux comprendre les préoccupations sous-jacentes. Nous exhortons les gouvernements et les Premières Nations à s'attaquer de concert aux problèmes systémiques identifiés avec une approche écosystémique holistique qui prend en considération l'accès financier et physique à la nourriture, en particulier les AT, et qui facilite une amélioration dans les comportements en santé. De nouveaux mécanismes élaborés conjointement avec les dirigeants des Premières Nations devraient viser à soutenir des modes de vie durables, culturellement sécuritaires et sains et à combler les lacunes en matière de nutrition et d'insécurité alimentaire.

RESUMEN

BACKGROUND: Anemia remains a public health problem in Rwanda, affecting 38% of young children and 17% of reproductive-aged women (Demographic and Health Survey [DHS] 2010). The importance of iron deficiency (ID) as a cause of anemia in Rwanda is not known. OBJECTIVE: We aimed to estimate the prevalence of ID and iron deficiency anemia (IDA) among young children and women in 2 provinces of Rwanda. METHODS: We conducted a cluster randomized survey, selecting 408 rural households each in the Northern and Southern Provinces of Rwanda in 2010. Anemia was defined as hemoglobin <110 g/L in children and <120 g/L in nonpregnant women after correction for altitude. We defined ID as (1) serum transferrin receptor (TfR) >8.3 mg/L or (2) serum ferritin (SF) <12 µg/L in children and <15 µg/L in nonpregnant women after correction for inflammation. RESULTS: The prevalence of anemia was 30.9% (95% confidence interval [CI], 26.4-35.8) in children (n = 577) and 11.2% (95% CI, 8.4-14.7) in women (n = 595). The prevalence of ID in children was 3.1% (95% CI, 1.8-5.1) as defined by high TfR and 5.9% (95% CI, 4.0-8.4) as defined by low SF. Similarly, 3.0% (95% CI, 1.8-4.8) of women had high TfR and 4.8% (95% CI, 3.2-7.2) had low SF. The prevalence of IDA (low SF with concurrent anemia) ranged from 1.4% (95% CI, 0.5-3.6) among women in the North to 5.6% (95% CI, 3.1-10.0) among children in the South. CONCLUSIONS: ID is likely not an important contributor to anemia in the Northern and Southern Provinces of Rwanda. This finding warrants further investigation into other causes of anemia.

RESUMEN

OBJECTIVE: To determine the impact that a 6-year maternal and child health project in rural Honduras had on maternal health services and outcomes, and to test the effect of level of father involvement on maternal health. METHODS: This was a program evaluation conducted through representative household surveys administered at baseline in 2007 and endline in 2011 using 30 cluster samples randomly-selected from the 229 participating communities. Within each cluster, 10 households having at least one mother-child pair were randomly selected to complete a questionnaire, for a total of about 300 respondents answering close to 100 questions each. Changes in key outcome variables from baseline to endline were tested using logistic regression, controlling for mother's education and father's involvement. RESULTS: There were improvements in most maternal health indicators, including an increase in women attending prenatal checkups (84% to 92%, P = 0.05) and institutional births (44% to 63%, P = 0.002). However, the involvement of the fathers decreased as reflected by the percentage of fathers accompanying mothers to prenatal checkups (48% to 41%, P = 0.01); the fathers' reported interest in prenatal care (74% to 52%, P = 0.0001); and fathers attending the birth (66% to 54%, P = 0.05). There was an interaction between the fathers' scores and the maternal outcomes, with a larger increase in institutional births among mothers with the least-involved fathers. CONCLUSIONS: Rather than the father's involvement being key, changes in the mothers may have led to increased institutional births. The project may have empowered women through early identification of pregnancy and stronger social connections encouraged by home visits and pregnancy clubs. This would have enabled even the women with unsupportive fathers to make healthier choices and achieve higher rates of institutional births.

Objetivo. Determinar la repercusión de un proyecto de salud maternoinfantil de 6 años de duración, en un entorno rural en Honduras, sobre los servicios de salud materna y los resultados asistenciales, y estudiar el efecto del grado de participación del padre en la salud materna. Métodos. El programa se evaluó mediante una serie de encuestas a los hogares representativos administradas al inicio de la intervención, en el 2007, y al concluir en el 2011, con 30 muestras de agrupaciones de familias elegidas al azar entre las 229 comunidades participantes. Dentro de cada agrupación, se seleccionaron aleatoriamente 10 familias compuestas al menos por una madre y un hijo para que contestasen un cuestionario, con lo cual se reunieron en total cerca de 300 personas encuestadas que respondieron casi 100 preguntas cada una. Se analizaron las variaciones en los criterios principales de valoración, entre el inicio y el final de la intervención, mediante técnicas de regresión logística, controlando el nivel educativo de la madre y la participación del padre. Resultados. Se observaron mejoras en la mayoría de los indicadores de salud materna, incluido un aumento de la cantidad de mujeres que acudieron a los controles prenatales (variación de 84% a 92%, P = 0,05) y de los partos atendidos en centros sanitarios (variación de 44% a 63%, P = 0,002). Sin embargo, se redujo la participación del padre, tal como refleja el porcentaje de padres que acompañan a la madre a los controles prenatales (variación de 48% a 41%, P = 0,01), el interés comunicado por el padre en la asistencia prenatal (variación de 74% a 52%, P = 0,0001) y el porcentaje de padres que estuvieron presentes en el parto (variación de 66% a 54%, P = 0,05). Se constató una interacción entre las puntuaciones paternas y los resultados asistenciales maternos, así como un aumento mayor de los partos en centros sanitarios en los casos en que el padre se involucraba menos. Conclusiones. Más que la participación del padre como factor clave, el aumento de los partos asistidos en centros sanitarios puede haberse debido a los cambios en las madres. Es posible que el proyecto empoderase a las mujeres y les permitiese percatarse antes de su embarazo y reforzar sus conexiones sociales con visitas domiciliarias y grupos de embarazadas. Esto habría facilitado, aun en los casos en los que el padre no se involucraba, que las mujeres tomasen decisiones más saludables, y que aumentasen las tasas de partos atendidos en centros sanitarios.

RESUMEN

OBJECTIVE:To examine dietary adequacy in the Andean area, including macro- and micronutrient intakes, with a particular focus on rural communities; to highlight nutrition priorities in the Andes; and to identify opportunities for improvement. METHODS: A comprehensive literature search was conducted, identifying published and grey literature in English and Spanish related to diet in the central Andean countries of Bolivia, Colombia, Ecuador, and Peru. Articles reporting data from dietary surveys or nutrition interventions were included. Thirty-four papers or reports published in 1969-2011 were included in the final review. The mean and variation in intakes by sex and age group of all presented nutrients were collated and the mean of means were calculated. RESULTS: Thiamin, niacin, and vitamin C intakes were usually adequate. Intakes of most other micronutrients, including iron, zinc, vitamin A, riboflavin, vitamin B12, folate, and zinc were low, likely resulting in high levels of inadequacy. Energy intakes were lower than requirements, but it is unlikely to be a common problem, rather, this result was probably due to the known tendency of most dietary survey tools to underreport intake. However, energy from fat intakes was very low, usually less than 20% of the total, and in some settings, less than 10%. CONCLUSIONS: The inadequate intake of some micronutrients is common in many developing countries, but the extremely low intake of dietary fat found in the central Andes is not. Increased consumption of animal-source foods would increase fat intakes, while addressing micronutrient deficiencies; however, the impact on the fragile ecosystem of the Andes needs considering. Indigenous crops, such as lupine bean, quinoa, and amaranth are also rich in fat or micronutrients.


OBJETIVO: Analizar la adecuación del régimen alimentario en la zona andina, incluidas las ingestas de macro y micronutrientes, prestando especial atención a las comunidades rurales; señalar las prioridades nutricionales en los Andes; y establecer las oportunidades de mejora. MÉTODOS: Se llevó a cabo una exhaustiva búsqueda bibliográfica, en la que se seleccionaron documentos publicados y procedentes de la literatura gris, en inglés y español, relacionados con el régimen alimentario en los países andinos centrales de Bolivia, Colombia, Ecuador y Perú. Se incluyeron artículos que aportaran datos de encuestas alimentarias o intervenciones nutricionales. En el análisis final, se incluyeron 34 artículos o informes publicados desde 1969 a 2011. Se recopilaron las medias y las variaciones de las ingestas de todos los nutrientes presentados según el sexo y el grupo de edad, y se calculó la correspondiente media de las medias. RESULTADOS: Las ingestas de tiamina, niacina y vitamina C eran generalmente adecuadas. Las ingestas de la mayor parte de los restantes micronutrientes, incluidos el hierro, el cinc, la vitamina A, la riboflavina, la vitamina B12 y el folato, eran bajas, lo que probablemente ocasionaba altos niveles de inadecuación. Los aportes energéticos eran inferiores a los requeridos, aunque es poco probable que ello constituya un problema frecuente; más bien, este resultado podría deberse a la tendencia conocida de notificar insuficientemente la ingesta en la mayor parte de las encuestas alimentarias. Sin embargo, el aporte energético procedente del consumo de grasas era muy reducido, generalmente por debajo del 20% del total, y en algunos lugares, por debajo del 10%. CONCLUSIONES: La ingesta inadecuada de algunos micronutrientes es frecuente en muchos países en desarrollo, aunque no es tan frecuente la ingesta extremadamente baja de grasa alimentaria observada en los Andes centrales. Un mayor consumo de alimentos de origen animal aumentaría la ingesta de grasas, al tiempo que abordaría las carencias en micronutrientes; sin embargo, debe tenerse en cuenta su posible repercusión sobre el frágil ecosistema de los Andes. Los cultivos autóctonos, como el frijol de altramuz, la quinoa y el amaranto, son también ricos en grasas o micronutrientes.

RESUMEN

BACKGROUND: It is well established that insecticide-treated bed nets (ITNs), in particular long-lasting, insecticidal nets (LLINs), can be used as one of the primary interventions for effective malaria control. A consistent gap between net ownership and use has been observed, indicating that factors exist that prevent an owned mosquito net from being used. One approach used in the context of LLIN campaigns is a post-distribution, door-to-door visit of households with educational messages and to physically assist with hang-up of nets. METHODS: A cluster randomized trial was conducted in the Plateaux Region of Togo to evaluate the effectiveness of different approaches to post-LLIN campaign home visits (number of visits and timing) by volunteers to enhance LLIN hang-up and utilization. RESULTS: It was found that, in general, households that received intervention visits, particularly the most recent intervention visit, had levels of use that were typically 5 to 10% higher than the control households, while access did not differ among control and intervention households. Eight months post-campaign, ITN use by all individuals, children under five years and women of reproductive age was 11.3 to 14.4 percentage points greater in the study arm that received all three intervention visits than in the control communities. In households that received one or two additional door-to-door visits, the majority of respondents indicated that the volunteer provided new information during the visit regarding the use and importance of ITNs despite having received previous multiple visits. CONCLUSIONS: The impact of the interventions appears to have been primarily through the delivery and reinforcement of key behaviour-change communication (BCC) messages regarding the importance of using an ITN and its care. Regardless of whether the respondents in fact received new information or had forgotten earlier information, this suggests that regular visits from community agents are useful in reinforcing key BCC messages.

RESUMEN

OBJECTIVE: To examine dietary adequacy in the Andean area, including macro- and micronutrient intakes, with a particular focus on rural communities; to highlight nutrition priorities in the Andes; and to identify opportunities for improvement. METHODS: A comprehensive literature search was conducted, identifying published and grey literature in English and Spanish related to diet in the central Andean countries of Bolivia, Colombia, Ecuador, and Peru. Articles reporting data from dietary surveys or nutrition interventions were included. Thirty-four papers or reports published in 1969-2011 were included in the final review. The mean and variation in intakes by sex and age group of all presented nutrients were collated and the mean of means were calculated. RESULTS: Thiamin, niacin, and vitamin C intakes were usually adequate. Intakes of most other micronutrients, including iron, zinc, vitamin A, riboflavin, vitamin B12, folate, and zinc were low, likely resulting in high levels of inadequacy. Energy intakes were lower than requirements, but it is unlikely to be a common problem, rather, this result was probably due to the known tendency of most dietary survey tools to underreport intake. However, energy from fat intakes was very low, usually less than 20% of the total, and in some settings, less than 10%. CONCLUSIONS: The inadequate intake of some micronutrients is common in many developing countries, but the extremely low intake of dietary fat found in the central Andes is not. Increased consumption of animal-source foods would increase fat intakes, while addressing micronutrient deficiencies; however, the impact on the fragile ecosystem of the Andes needs considering. Indigenous crops, such as lupine bean, quinoa, and amaranth are also rich in fat or micronutrients.

RESUMEN

BACKGROUND: The selection of food vehicles and fortification levels in food fortification programs may be made on the assumption of equitable intrahousehold distribution of food. There are concerns that biased intrahousehold distribution of food will make food-based interventions ineffective or unsafe. OBJECTIVE: To review available data documenting intrahousehold energy intake (as a proxy for food distribution) in low- and middle-income countries, and discuss the relevance for food fortification programs. METHODS: A literature search was done, selecting reports from low- and middle-income countries that included dietary data from adults and children. The references of relevant reports and all citations of relevant reports were scanned. Intrahousehold distribution of dietary energy was compared with individual energy requirements. RESULTS: Twenty-eight studies were identified covering 18 countries with as few as 20 and as many as 3,000 households per study. Intrahousehold distribution of food in most countries is relatively equitable, within a 20% margin. CONCLUSIONS: Within the limits of the available data, and in the absence of contrary data, it is reasonable to assume equitable intrahousehold distribution of food when designing food fortification programs; however, for program evaluation, individual assessment of intake is still needed.

RESUMEN

OBJECTIVE: To investigate whether children in households involved in a participatory agriculture and nutrition intervention had improved growth compared to children in matched comparable households and whether the level of involvement and length of time in the project had an effect on child growth. DESIGN: A prospective quasi-experimental study comparing baseline and follow-up data in 'intervention' villages with matched subjects in 'comparison' villages. Mixed model analyses were conducted on standardized child growth scores (weight- and height-for-age Z-scores), controlling for child age and testing for effects of length of time and intensity of village involvement in the intervention. SETTING: A participatory agriculture and nutrition project (the Soils, Food and Healthy Communities (SFHC) project) was initiated by Ekwendeni Hospital aimed at improving child nutritional status with smallholder farmers in a rural area in northern Malawi. Agricultural interventions involved intercropping legumes and visits from farmer researchers, while nutrition education involved home visits and group meetings. SUBJECTS: Participants in intervention villages were self-selected, and control participants were matched by age and household food security status of the child. Over a 6-year period, nine surveys were conducted, taking 3838 height and weight measures of children under the age of 3 years. RESULTS: There was an improvement over initial conditions of up to 0·6 in weight-for-age Z-score (WAZ; from -0·4 (sd 0·5) to 0·3 (sd 0·4)) for children in the longest involved villages, and an improvement over initial conditions of 0·8 in WAZ for children in the most intensely involved villages (from -0·6 (sd 0·4) to 0·2 (sd 0·4)). CONCLUSIONS: Long-term efforts to improve child nutrition through participatory agricultural interventions had a significant effect on child growth.

RESUMEN

Northern Potosi is one of the poorest parts of Bolivia with the highest indicators of rural poverty, malnutrition and food insecurity in the Bolivian Andes. The objective of this research was to characterize the levels of malnutrition and describe infant feeding practices in Potosi, Bolivia and use this information to develop an effective, gender sensitive and culturally relevant intervention encouraging good infant feeding practices. Standard methods were used to collect anthropometric data. Weight and height data were collected for 400 children under five years of age from 30 communities. In six of these communities, interviews and focus group discussions were conducted with 33 mothers and other families in addition to household observational data that were collected to describe infant feeding practices. Nearly 20% of children were underweight; stunting was widespread as well. 38% of mothers initiated breastfeeding 12 hours or more after birth. 39% of mothers initiated complementary feeding in the first three months following birth. The type of complementary food given to children was usually inadequate. With this research we could see that nutritional deficiencies often begin when the mother starts breastfeeding and when first introduced complementary feeding. Interventions aimed at improving maternal and child nutrition will require changes in parents' behavior, greater recognition and community support of the importance of child feeding, and the inclusion of strategies to reach young people, involve men, and make high quality nutrition promotion more widely available in the communities.

RESUMEN

OBJECTIVES: The goal of this research is to characterize the composition and nutrient adequacy of the diets in the northern region of the Department of Potosí, Bolivia. Communities in this semiarid, mountainous region are isolated and impoverished having the highest rates of child malnutrition and under-five mortality in the Americas. METHODS: A total of 2,222 twenty-four-hour dietary recalls were conducted in 30 communities during May and November 2006 and May and November 2007. Food composition data were compiled from diverse published sources and integrated with the recall data to estimate intakes of energy, protein, fat, carbohydrates, and seven micronutrients. Diets were characterized in terms of food sources, seasonality, and nutrient adequacy. RESULTS: The diet relies heavily on the potato and other tubers (54% of dietary energy) and grains (30% of dietary energy). Although crop production is seasonal, off-season consumption of chuño helps to minimize seasonal fluctuations in dietary energy intake. Despite relative monotony, intakes of iron, vitamin C, most B vitamins, and vitamin A in adults are probably adequate; riboflavin, calcium, and vitamin A intakes in children are low. Nevertheless, extremely low dietary fat intakes (approximately 3-9% of dietary energy from fat) likely prevent adequate absorption of fat-soluble vitamins as well as lead to deficiencies of essential fatty acids. CONCLUSIONS: Dietary inadequacies, especially of fats, may explain much of the poor health observed in northern Potosí. An improved diet may be possible through increasing production and intake of local fat-rich food sources such as small animals.
