RESUMO

The food system and climate are closely interconnected. Although most research has focused on the need to adopt a plant-based diet to help mitigate climate change, there is also an urgent need to examine the effects of climate change on food systems to adapt to climate change. A systems approach can help identify the pathways through which climate influences food systems, thereby ensuring that programmes combating malnutrition take climate into account. Although little is known about how climate considerations are currently incorporated into nutrition programming, climate information services have the potential to help target the delivery of interventions for at-risk populations and reduce climate-related disruption during their implementation. To ensure climate services provide timely information relevant to nutrition programmes, it is important to fill gaps in our knowledge about the influence of climate variability on food supply chains. A proposed roadmap for developing climate-sensitive nutrition programmes recommends: (i) research aimed at achieving a better understanding of the pathways through which climate influences diet and nutrition, including any time lags; (ii) the identification of entry points for climate information into the decision-making process for nutrition programme delivery; and (iii) capacity-building and training programmes to better equip public health practitioners with the knowledge, confidence and motivation to incorporate climate resilience into nutrition programmes. With sustained investment in capacity-building, data collection and analysis, climate information services can be developed to provide the data, analyses and forecasts needed to ensure nutrition programmes target their interventions where and when they are most needed.


Les systèmes alimentaire et climatique sont étroitement liés. Bien que la plupart des recherches se concentrent sur le besoin d'adopter un régime végétarien pour contribuer à atténuer le changement climatique, il est également urgent d'examiner les effets de ce changement climatique sur les systèmes alimentaires afin de les adapter en conséquence. Une approche systémique peut aider à déterminer dans quelle mesure le climat influence les systèmes alimentaires, et dès lors à faire en sorte que les programmes de lutte contre la malnutrition en tiennent compte. On ignore encore sous quelle forme les considérations climatiques sont actuellement intégrées dans les programmes de nutrition. Cependant, les services climatologiques peuvent contribuer à cibler le déploiement d'interventions pour les populations à risque, ainsi qu'à réduire les perturbations causées par le climat au cours de leur mise en œuvre. Pour veiller à ce que ces services fournissent à point nommé des informations utiles aux programmes de nutrition, il faut impérativement combler le manque de connaissances en matière d'impact des variations climatiques sur les chaînes d'approvisionnement alimentaire. La feuille de route proposée pour l'élaboration de programmes de nutrition adaptés au changement climatique recommande: (i) de mener des recherches visant à mieux comprendre dans quelle mesure le climat influence l'alimentation et la nutrition, en tenant compte des éventuels décalages temporelshoraires; (ii) d'identifier les points d'entrée des informations relatives au climat dans le processus décisionnel de déploiement des programmes alimentaires; et enfin, (iii) de développer des plans de formation et de renforcement des capacités afin que les professionnels de la santé publique disposent des connaissances, de la confiance et de la motivation nécessaires pour intégrer l'adaptation au changement climatique dans les programmes de nutrition. En investissant durablement dans le renforcement des capacités ainsi que dans la collecte et l'analyse de données, il est possible d'instaurer des services climatologiques qui communiqueront les informations, analyses et prévisions requises pour que les programmes de nutrition organisent leurs actions à l'endroit et au moment où elles deviennent indispensables.


El sistema alimentario y el clima están muy interconectados. Aunque la mayoría de las investigaciones se han centrado en la necesidad de adoptar una dieta basada en el consumo de plantas para ayudar a mitigar el cambio climático, también es urgente analizar los efectos del cambio climático en los sistemas alimentarios para adaptarse al mismo. Un enfoque sistémico puede ayudar a identificar las vías a través de las que el clima influye en los sistemas alimentarios, garantizando así que los programas de lucha contra la malnutrición tengan en cuenta el clima. Si bien se sabe poco sobre cómo se incorporan en la actualidad los aspectos climáticos a los programas de nutrición, los servicios de información climática tienen el potencial de ayudar a orientar las intervenciones hacia las poblaciones de riesgo y a reducir los trastornos relacionados con el clima durante su aplicación. Para garantizar que los servicios climáticos proporcionen información oportuna y relevante a los programas de nutrición, es importante solucionar las carencias de nuestros conocimientos sobre la influencia de la variabilidad climática en las cadenas de suministro de alimentos. Una hoja de ruta propuesta para desarrollar programas de nutrición sensibles al clima recomienda i) la investigación destinada a lograr una mejor comprensión de las vías a través de las que el clima influye en la dieta y en la nutrición, incluidos los retrasos; ii) la identificación de los puntos de entrada de la información sobre el clima en el proceso de toma de decisiones para la ejecución de los programas de nutrición; y iii) los programas de creación de capacidad y formación para preparar mejor a los profesionales de la salud pública con los conocimientos, la confianza y la motivación que permitan incorporar la adaptación al clima en los programas de nutrición. Si se invierte de manera sostenida en la creación de capacidades, la recopilación y el análisis de datos, se pueden desarrollar servicios de información climática que proporcionen los datos, los análisis y las previsiones necesarios para garantizar que los programas de nutrición orienten sus intervenciones donde y cuando más se necesiten.

RESUMO

Suboptimal diets drive the multiple burdens of malnutrition among women living in informal settlements. Women's food choices have important implications for their health, as well as that of their families. The purpose of this study was to examine how food choice decisions might differ across different age groups of women living in informal settlements in Nairobi, Kenya. Using in-depth interviews which incorporated a free-listing task, we determined the factors influencing food choice decisions in women in two informal settlements, Kibera and Mukuru. Among women in all age groups, we found income and food price to be the most salient factors influencing food choice decisions. Differences across age groups regarding food choice considerations included individual preference and quality being more salient factors amongst younger women while household preferences were more salient among older women. Women also reported making trade-offs between food affordability and other factors including time and nutrition, which led to sub-optimal diets. Our findings suggest that interventions in these settings may need to be tailored to specific age groups. Additionally, interventions may need to target both individual factors and the external food environment to help women overcome the trade-offs they often find themselves making in food choice decisions.

RESUMO

OBJECTIVE: The aim of this study was to examine the trade-offs related to the production and consumption of palm oil in Myanmar from a sustainable diets perspective. DESIGN: We used an enhanced value chain analysis approach that included semi-structured interviews with key stakeholders; market analyses to assess edible oils in markets and focus groups as well as surveys with consumers to ascertain their perceptions and practices related to edible oils. SETTING: Four settings in Myanmar (upper income urban; lower income urban; middle-income urban; lower income rural). PARTICIPANTS: Key stakeholders (n 12) from government, trade bodies and civil society organisations were included in the interviews. Women from each of the regions participated in four focus groups (n 32), and a convenience sample of male and female consumers participated in the surveys (n 362). RESULTS: We found mistrust of the oil sector overall. Poor production practices, leading to low yields, limit the economic viability of oil palm production in Myanmar and contribute to negative environmental (e.g. deforestation) and social outcomes (e.g. land conflicts). Consumers demonstrated low preferences for palm oil as compared with traditional oils from a taste, health and transparency perspective; however, they indicated that its relative low cost led to its purchase over other oils. CONCLUSIONS: The Burmese example suggests that there may be limited benefits, and significant costs, of investing in palm oil production in regions where there are coordinating disincentives from a sustainable diets perspective. However, if oil palm cultivation is to continue, there are opportunities to improve its economic viability and environmental sustainability.

RESUMO

In the United States, typical dietary patterns are not necessarily healthy and sustainable. In order to shift diets, we need to provide support to individuals in a way that reflects what matters most to them. In this study, we aimed to identify the considerations that are most important to individuals regarding food-related decisions, and to determine how those considerations relate to specific foods, with a focus on health and environmental sustainability. In a sequential mixed-methods design, we first conducted 27 semi-structured interviews with participants in California and Nebraska. These interviews included a free-listing activity, where we used a technical construct of salience, Smith's S Index, to identify the considerations that were most important to our participants. We followed up with 20 of those participants to complete a pile-sorting survey, where participants sorted and rated 42 food items for price, taste, health, convenience, familiarity, and environmental impact. Our findings showed that the most salient considerations cited by our participants were price, health, taste, and time. There was consensus for how participants rated the foods for price, taste, convenience, and familiarity. However, there was only weak consensus for how participants rated the foods for health impact, and no consensus for how participants rated the foods for environmental impact. There was also disagreement on how to sort new plant-based products intended to replace or substitute meat and other animal-based foods. These findings have implications for how to communicate about healthy and sustainable diets. They highlight conflicting considerations, disagreement in classification of new products, and limited consensus for perceived health and environmental impact of foods, which present challenges to the achievement of diets that are healthy and environmentally sustainable in the United States.

RESUMO

OBJECTIVE: To identify opportunities and challenges for the promotion of healthy, sustainable oil consumption in India. DESIGN: We use a framework for policy space analysis which distinguishes between policy context, process and characteristics. SETTING: We focus on the Indian edible oils sector and on factors shaping the policy space at a national level. PARTICIPANTS: The study is based on the analysis of policy documents and semi-structured interviews with key experts and stakeholders in the edible oils sector. RESULTS: We find opportunities associated with the emergence of multisectoral policy frameworks for climate adaptation and non-communicable disease (NCD) prevention at a national level which explicitly include the oils sector, the existence of structures for sectoral policy coordination, some supportive factors for the translation of nutrition evidence into practice, and the possibility of integrating nutrition-sensitive approaches within current state-led agricultural interventions. However, the trade-offs perceived across sustainability, NCD prevention and food security objectives in the vegetable oils sector are considered a barrier for policy influence and implementation. Sustainability and nutrition advocates tend to focus on different segments of the value chain, missing potential synergies. Moreover, policy priorities are dominated by historical concerns for food security, understood as energy provision, as well as economic and strategic priorities. CONCLUSIONS: Systematic efforts towards identifying synergistic approaches, from agricultural production to distribution of edible oils, as well as increased involvement of nutrition advocates with upstream policies in the oils sector, could increase policy influence for advocates of both nutrition and sustainability.

RESUMO

OBJECTIVE: To examine consumers' perceptions of their food environments, their food consumption patterns and preferences, and to better understand the attributes of foods that are available within food environments in Myanmar. DESIGN: An exploratory mixed-methods study using a combination of focus group discussions, market and consumer surveys. SETTING: Four study settings in Myanmar were included: an upper-income township of Yangon; a lower-income township of Yangon; a middle-income township in the southern Myanmar town of Dawei; and a lower-income village in the country's dry zone of Magway. PARTICIPANTS: Thirty-two women participated in the focus groups discussions, twenty market surveys were conducted and 362 consumers (both men and women) completed food consumption surveys. RESULTS: Focus group participants indicated that the availability of a diverse range of foods had increased over time, while the quality of foods had decreased. Health was seen primarily through the lens of food safety and there was an overall lack of knowledge about which foods were more or less healthy. Consumers preferred fruits, vegetables and red meat compared with highly processed snack foods/beverages. Although consumers reported low intakes of highly processed snack foods, Burmese street food was consumed in high quantities. The market surveys suggested that fresh, minimally processed and highly processed foods were available at all markets across the study settings. CONCLUSIONS: Consumers are exposed to a variety of foods, of varying quality, within their food environments in Myanmar. Interventions aimed at increasing consumer knowledge regarding healthy diets and improving food safety are needed.

RESUMO

Mobile health (mHealth) interventions have the potential to improve infant and young child feeding (IYCF) practices; however, gaps in the literature remain regarding their design, implementation, and effectiveness. The aims of this study were to design an mHealth voice messaging intervention delivered to mothers and fathers targeting IYCF practices and examine its implementation and impact in households with children 6-23 months in three rural villages in Senegal. We conducted focus groups (n = 6) to inform the intervention development. We then conducted a pilot study (n = 47 households) to examine the impact of the intervention on IYCF practices of children 6-23 months. Voice messages were sent to the children's mothers and fathers over a period of 4 weeks (two messages per week; eight messages in total), and 24-hr dietary recalls and food frequency questionnaires (FFQs) were conducted before and immediately after the implementation of the mHealth intervention to examine its impact on IYCF practices. Overall, three of the eight behaviours increased and one decreased. There was a significant increase in the number of children that consumed fish (60% vs. 94%; p = .008) as measured by the 24-hr recall after the completion of the intervention. We also found significantly higher frequency of egg (p = .026), fish (p = .004), and thick porridge (p = .002) consumption in the previous 7 days measured by the FFQ. Our findings suggest that voice messaging IYCF interventions in Senegal have the potential to improve IYCF behaviours among young children in the short term. Future research should entail scaling-up the intervention and examining its sustainability over the long-term.

RESUMO

The World Health Organization has recommended that Member States consider taxing energy-dense beverages and foods and/or subsidizing nutrient-rich foods to improve diets and prevent noncommunicable diseases. Numerous countries have either implemented taxes on energy-dense beverages and foods or are considering the implementation of such taxes. However, several major challenges to the implementation of fiscal policies to improve diets and prevent noncommunicable diseases remain. Some of these challenges relate to the cross-sectoral nature of the relevant interventions. For example, as health and economic policy-makers have different administrative concerns, performance indicators and priorities, they often consider different forms of evidence in their decision-making. In this paper, we describe the evidence base for diet-related interventions based on fiscal policies and consider the key questions that need to be asked by both health and economic policy-makers. From the health sector's perspective, there is most evidence for the impact of taxes and subsidies on diets, with less evidence on their impacts on body weight or health. We highlight the importance of scope, the role of industry, the use of revenue and regressive taxes in informing policy decisions.


L'Organisation mondiale de la Santé a recommandé aux États membres d'envisager de taxer les boissons et aliments à haute teneur énergétique et/ou de subventionner les denrées riches en nutriments, en vue d'améliorer les régimes alimentaires et de prévenir les maladies non transmissibles. Aujourd'hui, nombreux sont les pays à avoir instauré des taxes sur les boissons et aliments à haute teneur énergétique ou à envisager de le faire. Néanmoins, d'importants défis subsistent pour la mise en application de ce type de politiques fiscales. Certains sont liés à la nature intersectorielle des interventions appropriées. Par exemple, comme les responsables des politiques économiques et les responsables des politiques de santé ont des préoccupations administratives, des priorités et des indicateurs de performances différents, ils s'appuient souvent sur différentes formes de données dans leur prise de décisions. Dans le présent document, nous décrivons les données probantes susceptibles d'orienter les interventions sur l'alimentation fondées sur des politiques fiscales et nous évoquons les principales problématiques auxquelles doivent répondre à la fois les responsables des politiques économiques et les responsables des politiques de santé. D'un point de vue de santé publique, les preuves de l'impact des taxes et subventions sur les habitudes alimentaires sont plus nombreuses que les preuves de leur impact sur le poids ou la santé. Nous abordons également l'importance du périmètre d'action, le rôle de l'industrie, l'utilisation des recettes fiscales et la régressivité des taxes, dans l'optique d'éclairer les décisions politiques.


La Organización Mundial de la Salud ha recomendado a los Estados Miembros considerar la posibilidad de aplicar un impuesto a las bebidas y los alimentos de alto contenido energético y/o subvencionar los alimentos ricos en nutrientes para mejorar las dietas y prevenir enfermedades no contagiosas. Numerosos países ya aplican impuestos a bebidas y alimentos de alto contenido energético o consideran la implementación de dichos impuestos. Sin embargo, persisten varios desafíos importantes para la implementación de políticas fiscales para mejorar las dietas y prevenir las enfermedades no contagiosas. Algunos de estos desafíos están relacionados con la naturaleza intersectorial de las intervenciones correspondientes. Por ejemplo, puesto que los encargados de la formulación de políticas de salud y economía tienen diferentes preocupaciones administrativas, indicadores de rendimiento y prioridades, a menudo tienen en cuenta diferentes formas de pruebas en su toma de decisiones. En este documento, se describe la base de pruebas para intervenciones relacionadas con la dieta basadas en políticas fiscales y se consideran las preguntas clave que deben formular tanto los responsables de la política económica como de la de salud. Desde la perspectiva del sector de la salud, existen muchas pruebas del impacto de los impuestos y subsidios en las dietas, con menos pruebas de sus impactos sobre el peso o la salud corporal. Se destaca la importancia del alcance, el papel de la industria, el uso de los ingresos y los impuestos regresivos para informar sobre las decisiones políticas.

RESUMO

OBJECTIVE: To systematically review the design, implementation and effectiveness of mass media and nutrition education interventions for improving infant and young child feeding (IYCF) practices and related psychosocial factors. DESIGN: A search of PubMed, Embase and PsycINFO databases, a Google search, and a consultation with experts in the field of IYCF performed in July 2016. SETTING: Low- and middle-income countries, as defined by the World Bank Group. SUBJECTS: Eligible studies: included a mass media component (with or without nutrition education); conducted a pre-post evaluation (with or without a control group); assessed IYCF knowledge, attitudes, beliefs and/or practices; and were published in English between 2000 and present. RESULTS: Eighteen unique studies were identified that examined the effect of mass media (types included: television; print; voice and/or SMS (text) messages; radio; megaphones/loudspeakers; videos; social media; songs/dramas) and nutrition education interventions on IYCF practices within thirteen countries. Of these, fifteen studies reported improvements in breast- and/or complementary feeding practices, using indicators recommended by the WHO, and six studies reported improvements in related psychosocial factors. However, little detail was provided on the use of formative research, a formal behaviour change theory and behaviour change techniques. Few studies reported both dose delivered and participants' exposure to the intervention. CONCLUSIONS: Despite evidence of effectiveness, few common elements in the design of interventions were identified. Future research should consistently report these details to open the 'black box' of IYCF interventions, identify effective design components and ensure replicability.

RESUMO

OBJECTIVE: The development of food policy is strongly influenced by the understanding and position actors adopt in their 'framing' of sustainability. The Australian Government developed a National Food Plan (2010-2013). In public consultations on the National Food Plan Green Paper, the government sought stakeholders' views on sustainability. The present study examined the way in which the food industry and civil society organizations framed sustainability in their submissions to the Green Paper. DESIGN: Submissions by food industry actors and civil society organizations were analysed using a framing matrix that examined positioning, drivers, underlying principles and policy solutions related to sustainability. Submissions were open coded and subsequently organized based on themes within the framing matrix. SETTING: Australia. SUBJECTS: One hundred and twenty-four written submissions (1420 pages). RESULTS: While submissions from industry and civil society organizations often framed sustainability similarly, there were also major differences. Civil society organizations were more likely to make the link between the food supply and population health, while industry was more likely to focus on economic sustainability. Both viewed consumer demand as a driver of sustainability, welcomed the idea of a whole-of-government approach and stressed the need for investment in research and development to improve productivity and sustainable farming practices. CONCLUSIONS: The meaning of sustainability shifted throughout the policy process. There are opportunities for creating shared value in food policy, where the health, environment and economic dimensions of sustainability can be compatible. However, despite pockets of optimism there is a need for a shared vision of sustainability if Australia is to have a food policy integrating these dimensions.

RESUMO

BACKGROUND: The World Health Organization (WHO) recommends virtually eliminating trans fat from the global food supply. Although several high-income countries have successfully reduced trans fat levels in foods, low- and middle-income countries such as India face additional challenges to its removal from the food supply. This study provides a systems analysis of the Indian food chain to assess intervention options for reducing trans fat intake in low-income consumers. METHODS: Data were collected at the manufacturer, retailer and consumer levels. Qualitative interviews were conducted with vanaspati manufacturers (n = 13) and local food vendors (n = 44). Laboratory analyses (n = 39) of street foods/snacks sold by the vendors were also conducted. Trans fat and snack intakes were also examined in low-income consumers in two rural villages (n = 260) and an urban slum (n = 261). RESULTS: Manufacturers of vanaspati described reducing trans fat levels as feasible but identified challenges in using healthier oils. The fat content of sampled oils from street vendors contained high levels of saturated fat (24.7-69.3 % of total fat) and trans fat (0.1-29.9 % of total fat). Households were consuming snacks high in trans fat as part of daily diets (31 % village and 84.3 % of slum households) and 4 % of rural and 13 % of urban households exceeded WHO recommendations for trans fat intakes. CONCLUSIONS: A multisectoral food chain approach to reducing trans fat is needed in India and likely in other low- and middle-income countries worldwide. This will require investment in development of competitively priced bakery shortenings and economic incentives for manufacturing foods using healthier oils. Increased production of healthier oils will also be required alongside these investments, which will become increasingly important as more and more countries begin investing in palm oil production.

RESUMO

India is undergoing a shift in consumption from traditional foods to processed foods high in sugar, salt and fat. Partially hydrogenated vegetable oils (PHVOs) high in trans-fat are often used in processed foods in India given their low cost and extended shelf life. The World Health Organization has called for the elimination of PHVOs from the global food supply and recommends their replacement with polyunsaturated fat to maximize health benefits. This study examined barriers to replacing industrially produced trans-fat in the Indian food supply and systematically identified potential policy solutions to assist the government in encouraging its removal and replacement with healthier polyunsaturated fat. A combination of food supply chain analysis and semi-structured interviews with key stakeholders was conducted. The main barriers faced by the food-processing sector in terms of reducing use of trans-fat and replacing it with healthier oils in India were the low availability and high cost of oils high in polyunsaturated fats leading to a reliance on palm oil (high in saturated fat) and the low use of those healthier oils in product reformulation. Improved integration between farmers and processors, investment in technology and pricing strategies to incentivize use of healthier oils for product reformulation were identified as policy options. Food processors have trouble accessing sufficient affordable healthy oils for product reformulation, but existing incentives aimed at supporting food processing could be tweaked to ensure a greater supply of healthy oils with the potential to improve population health.

RESUMO

PURPOSE: This study describes dietary changes among university students who completed a travel study program. METHODS: Seventeen undergraduate nutrition students travelled from Edmonton to Italy for 6 weeks to take 2 courses on the Mediterranean diet. In both locations students completed a 24-h dietary recall and a Food Frequency Questionnaire to assess their Mediterranean Diet Quality Index Score (MDQIS). A MDQIS of 48 indicates perfect adherence to eating patterns of the Traditional Healthy Mediterranean Diet Pyramid (THMDP). RESULTS: While in Italy students altered their diets in positive ways (increased consumption of fish and seafood (P = 0.002), wine (P < 0.0001), and olive oil (P = 0.001)) and negative ways (increased consumption of sweets (P = 0.027), poultry (P = 0.001), and meat (P = 0.049)) relative to the THMDP. Students had a significant increase in the percentage of energy from polyunsaturated and monounsaturated fatty acids and alcohol. The MDQIS was low in Edmonton (21.9 ± 3.7) and Italy (22.9 ± 3.9). CONCLUSIONS: The overall dietary pattern of students did not adhere to the THMDP. Education about the THMDP and living in Italy for 6 weeks was insufficient to change students' dietary patterns to one characterized as traditional Mediterranean. The findings highlight the challenges of implementing dietary changes even with nutrition education and increased food access.

RESUMO

The national Government of India has published draft regulation proposing a 5% upper limit of trans fat in partially hydrogenated vegetable oils (PHVOs). Global recommendations are to replace PHVOs with unsaturated fat but it is not known whether this will be feasible in India. We systematically identified policy options to address the three major underlying agricultural sector issues that influence reformulation with healthier oils: the low productivity of domestically produced oilseeds leading to a reliance on palm oil imports, supply chain wastage, and the low availability of oils high in unsaturated fats. Strengthening domestic supply chains in India will be necessary to maximize health gains associated with product reformulation.

RESUMO

OBJECTIVE: To systematically review evidence for the effectiveness of policies, including self-regulation, aimed at reducing industrially produced trans fatty acids (TFAs) in food. METHODS: The Medline, Embase and Cinahl databases were searched to identify peer-reviewed articles examining the effect of TFA policies. In addition, the first 20 pages of Google searches were examined for articles from the grey literature. A study was included if: (i) it was empirical and conducted in a "real-world" setting (i.e. modelling studies were excluded); (ii) it examined a TFA policy involving, for example, labelling, voluntary limits or bans; and (iii) it examined a policy's effect on TFA levels in food, people's diets, blood or breast milk. FINDINGS: Twenty-six articles met the inclusion criteria: 5 involved voluntary self-regulation; 8, labelling alone; 4, labelling and voluntary limits; 5, local bans and 4, national bans. Overall, the TFA content of food decreased with all types of policy intervention. In general, saturated fat levels increased or decreased, depending on the product type, and total fat content remained stable. National and local bans were most effective at eliminating TFAs from the food supply, whereas mandatory TFA labelling and voluntary TFA limits had a varying degree of success, which largely depended on food category. CONCLUSION: Policies aimed at restricting the TFA content of food were associated with significant reductions in TFA levels, without increasing total fat content. Such policies are feasible, achievable and likely to have an effect on public health.

RESUMO

OBJECTIVE: India has proposed legislating an upper limit of trans fat in partially hydrogenated vegetable oils and mandating trans fat labelling in an effort to reduce intakes. The objective of the present study was to examine the complexities of regulating trans fat in India by examining the policy processes involved and the perceived implementation challenges. DESIGN: Semi-structured interviews (n 18) were conducted with key informants from various sectors. Interviewees were asked about sources of trans fat in the food supply, existing policies that may influence trans fats and perceived challenges related to the proposed trans fat regulation, in addition to questions tailored to their area of expertise. Interview data were organised based on common themes. SETTING: Interviews were conducted in India. SUBJECTS: Interviewees were key informants from various sectors including agriculture, trade, industry and health. RESULTS: Several themes were identified related to the complexity of regulating trans fat in India. A lack of trans fat awareness, the large unorganised retail sector, a need for suitable alternative products that are both acceptable to consumers and affordable, and a need to build capacity were crucial factors affecting India's ability to successfully regulate trans fat. The limited number of food inspectors will create an additional challenge in terms of enforcement of trans fat regulation. CONCLUSIONS: Although India will face challenges in regulating trans fat, legislating an upper limit of trans fat in partially hydrogenated vegetable oils will likely be the most effective approach to reducing it in the food supply. Ongoing engagement with industry, agriculture, trade and processing sectors will prove essential in terms of product reformulation.

RESUMO

BACKGROUND: The consumption of partially hydrogenated vegetable oils (PHVOs) high in trans fat is associated with an increased risk of cardiovascular disease and other non-communicable diseases. In response to high intakes of PHVOs, the Indian government has proposed regulation to set limits on the amount of trans fat permissible in PHVOs. Global recommendations are to replace PHVOs with polyunsaturated fatty acids (PUFAs) in order to optimise health benefits; however, little is known about the practicalities of implementation in low-income settings. The aim of this study was to examine the technical and economic feasibility of reducing trans fat in PHVOs and reformulating it using healthier fats. METHODS: Thirteen semi-structured interviews were conducted with manufacturers and technical experts of PHVOs in India. Data were open-coded and organised according to key themes. RESULTS: Interviewees indicated that reformulating PHVOs was both economically and technically feasible provided that trans fat regulation takes account of the food technology challenges associated with product reformulation. However, there will be challenges in maintaining the physical properties that consumers prefer while reducing the trans fat in PHVOs. The availability of input oils was not seen to be a problem because of the low cost and high availability of imported palm oil, which was the input oil of choice for industry. Most interviewees were not concerned about the potential increase in saturated fat associated with increased use of palm oil and were not planning to use PUFAs in product reformulation. Interviewees indicated that many smaller manufacturers would not have sufficient capacity to reformulate products to reduce trans fat. CONCLUSIONS: Reformulating PHVOs to reduce trans fat in India is feasible; however, a collision course exists where the public health goal to replace PHVOs with PUFA are opposed to the goals of industry to produce a cheap alternative product that meets consumer preferences. Ensuring that product reformulation is done in a way that maximises health benefits will require shifts in knowledge and subsequent demand of products, decreased reliance on palm oil, investment in research and development and increased capacity for smaller manufacturers.

RESUMO

Behavior change communication (BCC) strategies have the potential to improve infant feeding and nutrition outcomes among infants and young children in low- and middle-income countries. More recently, there has been a shift toward the adoption of mHealth interventions-the use of mobile phones to transmit health-related information or direct care-to promote recommended BCC strategies among the caregivers of infants and young children. In Senegal, most infants and young children are not fed according to recommended practices leading to a high prevalence of undernutrition and micronutrient deficiencies. The aims of this cluster randomized control trial, using an effectiveness-implementation (type 1) hybrid design, were to: (1) determine the impact of an mHealth IYCF intervention on IYCF practices and nutrition outcomes; and (2) examine the implementation, costs, and opportunities for scaling up the mHealth messaging intervention. The trial was conducted in three regions in Senegal (Thies, Fatick, Diourbel) with 488 mother, father and children (6-23 months) triads. The intervention included 8 scripted messages, that underwent cognitive testing prior to the intervention implementation, and 8 unscripted messages from positive deviants. One voice message and one text message were sent each week to members of our experimental group for a 16-week period. The impact of the intervention was assessed through a household survey, 24-h dietary recall, and hemoglobin measurements before and after the intervention implementation. The primary outcomes were minimal acceptable diet (MAD) and anemia. We also included a total of 54 participants in nine focus groups held with mothers and fathers and semi-structured interviews with Badienou Gox (i.e., community health workers) (n = 6) and national partners and program implementers (n = 6) to examine the intervention implementation process. The study was registered prior to data collection on Clinicaltrials.gov (Identifier: NCT05374837).

RESUMO

Hunger and food insecurity has worsened due to the COVID-19 pandemic. The types of food environments (e.g., natural/built) that people can access may improve household resilience to food-system shocks. This paper examines (1) urban and rural differences in the perceived influence of the COVID-19 pandemic on agricultural, livelihoods, food environment attributes, diets; and (2) whether access to different food environments was associated with food security. A two-part telephonic survey (COVID-19 Surveillance Community Action Network Food Systems Tool and Household Food Insecurity Access Scale) was conducted in Western Kenya (n = 173) and an informal settlement in Nairobi (n = 144) in January/February 2021. Limitations on the acquisition of farm inputs and movement restrictions had an adverse impact on agriculture and food sales. Urban residents reported a more significant impact on livelihoods (97% vs. 87%, p < 0.001), with day laborers being the most impacted. Rural respondents reported access to significantly more food environments and lower food insecurity. Multiple linear regression analysis revealed that younger respondents, ≤1 income source, had more difficulty acquiring food, decreased access to cultivated environments, and increased access to informal markets were predictors for higher food insecurity. These data indicate that access to specific types of food environments may improve household resilience.

RESUMO

The food environments that people have access to shape their food choices. The purpose of this study was to use mixed methods to characterize the external food environment in informal settlements in Nairobi, Kenya and to examine the individual factors that influence the way in which women interact with those environments to make food choices. We used a combination of food environment assessments (vendor mapping, collection of food prices, food quality assessments) and five focus group discussions with women (n = 26) in four villages within two informal settlements in Nairobi (Mukuru and Kibera) to better understand the drivers of food choice. We found a large number (n = 1163) of vendors selling a variety of food within the settlements. The highest number of vendors were selling fruits and/or vegetables; however, there was limited diversity of fruits available. Animal-source foods were considered relatively expensive as compared to plant-based foods, including prepared fried snacks. We found that the way women interacted with their food environments was influenced by individual factors such as income, time, convenience, and preferences. Our findings suggest that interventions targeting both the external food environment as well as individual factors such as income will be necessary to support healthy diets among low-income populations living in informal settlements in Kenya.
