Are the 2019 Canada's Food Guide Recommendations on Healthy Food Choices Consistent with the EAT-Lancet Reference Diet from Sustainable Food Systems?

BACKGROUND: The diet proposed by the EAT-Lancet Commission, which supports both health and environmental sustainability, provides an opportunity to assess the sustainability of food-based dietary guidelines. OBJECTIVES: The primary objective was to assess the alignment of the 2019 Canada's Food Guide (CFG) with the EAT-Lancet diet. To do so, an index assessing adherence to the EAT-Lancet diet was developed and evaluated. METHODS: Data from 1147 adults were used from the cross-sectional PRÉDicteurs Individuals, Sociaux et Environnementaux (PREDISE) study conducted between 2015 and 2017 in the province of Québec. The EAT-Lancet Dietary Index (EAT-I) was developed to evaluate adherence to the EAT-Lancet diet. Adherence to the 2019 CFG was assessed using the Healthy Eating Food Index (HEFI)-2019. Associations between the HEFI-2019 score and component scores and the EAT-I score were examined using linear regression models. RESULTS: The mean EAT-I score (/80) in this population was 33.4 points [95% confidence interval (CI): 32.2, 34.6]. EAT-I scores were consistent with expected differences in diet quality between females and males (+6.9 points, 95% CI: 4.8, 9.0) and between adults aged 50-65 y and 18-34 y (+4.3 points, 95% CI: 1.6, 7.0). The mean HEFI-2019 (/80) score was 44.9 points (95% CI: 44.1, 45.7). The HEFI-2019 was strongly associated with the EAT-I (ß = 0.76, 95% CI: 0.72, 0.80). Among the 10 components of the HEFI-2019, components such as the whole-grain foods (ß =4.01, 95% CI: 3.49, 4.52), grain foods ratio (ß =3.65, 95% CI: 3.24, 4.07), plant-based protein foods (ß =2.41, 95% CI: 2.03, 2.78), and fatty acids ratio (ß =3.12, 95% CI: 2.72, 3.51) showed the strongest associations with the EAT-I. CONCLUSIONS: These results suggest that recommendations in the 2019 CFG are largely coherent with the EAT-Lancet diet underscoring the complementarity and compatibility of the 2019 CFG for sustainability and health promotion purposes.

Perspective: Mexico's Experience in Building a Toolkit for Obesity and Noncommunicable Diseases Prevention.

Noncommunicable diseases (NCDs) are a leading cause of death and disability worldwide, with a higher risk of death in low- and middle-income countries. Diet and excess weight are risk factors for NCDs. In Mexico, the prevalence of overweight and obesity increased dramatically in the last 30 y and is among the highest in the world. To address this public health problem, governments and public health professionals have several policy instruments available. In this study, we present the policy instruments currently approved in Mexico, which include fiscal, informational, and authoritative tools that aim to improve the food environment and promote healthy behaviors (taxes, school food guidelines, front-of-pack labeling, marketing regulations, and dietary guidelines). These types of interventions are important in regions like Latin America, where social inequities and poor access to information are common, and individual healthy choices are often limited. These interventions target the environments in which individuals live, study, work, and seek entertainment, while limiting access to unhealthy choices and offering information to promote healthy alternatives. The Mexican experience in design, implementation, and evaluation of policies to improve the food environment can be useful for other low- and middle-income countries facing similar challenges.

Expert opinion survey on Israel's food system: implications for food and health policies.

BACKGROUND: While there has been increasing global recognition and impetus for action to transform food systems towards greater food security, sustainability and better health outcomes, Israel has only recently begun to focus on the diverse challenges of its food system and its potential for transformation. METHODS: An expert opinion survey (n = 50) on Israel's food system was conducted as part of a larger study on the systemic features of Israel's food system transition to understand its policy gaps and find strategies towards a healthy and sustainable food system. The survey ranks the relevance and importance of food system challenges and policy preferences. Policy implications are then examined by identifying potential priorities, gaps and dissensus. RESULTS: The survey finds that there is a majority agreement (76%) that Israel's food policies are lacking or severely lacking. Respondents relate strongly to both concepts of nutritional security (90% think that access to nutritious food is relevant or highly relevant) and national food security (more than 80% perceive food security as part of national security). Respondents overwhelmingly recognize the benefits of Israeli agriculture with 60-90% agreeing or strongly agreeing that it benefits food security, economic value and national identity. Top-ranked problems include overall systemic problems such as the lack of national goals, strategic planning, and integrated policymaking across ministries, and specific ones such as food waste, costly farming inputs, and food affordability. The most preferred policy actions include establishing a national strategy for food and agriculture, making food affordable for vulnerable households, and incentivising sustainable farming methods. The key policy gaps include the lack of resilience in agriculture and the food system, insufficient data and knowledge for policy action, inadequate attention to the regulation of the food industry for better health and inadequate food policy attention for minority groups. CONCLUSIONS: Building on this study's findings, further policy research and implementation areas to be covered include government responsibility for universal food security, strategic systemic policies for food systems, prevention and preparedness for future crises, and promoting resilience. The way forward may best be through an inter-ministerial committee with the responsibility, budgets, mandate and executive authority to plan data-driven policies for a sustainable food system for Israel's future.

Agrobiodiversity-Based Landscape Design in Urban Areas.

Agrobiodiversity represents a system of biological organisms that contribute to agri-food production. In a context marked by a significant loss of food-relevant species and a reduction in their genetic diversity, the adoption of strategies to preserve and enhance the diversity of genetic resources that support and complement agricultural production has become a global challenge. Many sustainable development strategies outlined in recent years directly and indirectly attribute a crucial role to agrobiodiversity in meeting food needs, ensuring food system security, promoting food justice, and enhancing well-being in modern living environments. This contribution aims to analyze the process of knowledge and awareness that has led many cities to plan their urban development by investing in the agricultural matrix and to address the design of open spaces with agricultural biodiversity.

Modelling food policies in Italian urban agendas in the time of Covid-19: Experiences, challenges and opportunities.

Global food systems are broken and in need of profound change. These imbalances and vulnerabilities are particularly strong in cities, where most of the global population lives and that are at the core of the major challenges linked with food production and consumption. The food system transition needs cities as key game-changers towards more sustainable, equitable, healthier and fairer food systems. Against this backdrop, the present article analyses the role of food policies within urban policies, with a focus on Italian cities. In particular, the article discusses data collected from representatives of 100 municipalities across Northern, Central and Southern Italy. Moreover, it addresses the types of policies and initiatives adopted at the local level, the main obstacles encountered, the role of national and international city networks and the impact of Covid-19 on urban food security, with the aim to identify potential models of urban food policies as a structural component of a broader urban agenda. By doing this, the article aims at filling a research gap in current literature, as it is the first large-scale survey on urban food policies in Italy, identifying models of urban food policies that are already being developed within broader urban development agendas.

Aplicación del modelo de perfiles nutricionales OMS 2015 para la reducción de azúcares añadidos en lácteos infantiles / ation of WHO 2015 nutritional profile model for the reduction of added sugars in children's dairy

En los últimos 20 años hemos duplicado las tasas de obesidad. Un 67 % de la población no tiene un peso adecuado y el 40 % de la población infantil sufre obesidad o sobrepeso en España. Esto deriva en graves enfermedades. Para evitarlo, es necesario un plan nacional de lucha contra la obesidad, con estrategias de prevención y terapéuticas para no seguir incrementando estos datos en 2030.Entre los factores causantes de la obesidad infantil se encuentran los malos hábitos de alimentación, además de la falta de actividad física y un uso excesivo de pantallas. Además, existe una brecha social importante. La obesidad infantil afecta especialmente a familias con menor poder adquisitivo (el 54 %), que no tienen acceso a una alimentación saludable ni las herramientas necesarias o el conocimiento para promover la salud a sus hijos e hijas a través de la alimentación.La Oficina Regional de la Organización Mundial de la Salud (OMS) para Europa desarrolló un modelo de perfil de nutrientes en 2015, específicamente a efectos de restringir la comercialización de alimentos dirigida a los niños, un modelo que se plantea desde la comunidad científica como una herramienta de referencia a la hora de establecer políticas y mejoras en pro de la salud pública, con el fin de facilitar a las familias el acceso a alimentos con un mejor perfil y valor nutricional. (AU)

In the last 20 years we have doubled obesity rates. In Spain, 67 % of the population does not have an adequate weight and 40 % of the child population suffers from obesity or overweight. This leads to serious diseases. To avoid this, a national plan to fight obesity is required, with prevention and therapeutic strategies so as not to continue increasing these data in 2030. Among the factors that cause childhood obesity are poor eating habits as well as a lack of physical activity and excessive use of screens.In addition, there is a significant social gap. Childhood obesity especially affects families with lower purchasing power (54 %) who do not have access to a healthy diet or the necessary tools or knowledge to promote health to their sons and daughters through food.The World Health Organization (WHO) Regional Office for Europe developed a nutrient profile model in 2015, specifically for the purpose of restricting the marketing of foods aimed at children. This model is considered by the scientific community as a reference tool when it comes to establish policies and improvements in favor of public health, in order to provide families with access to food with a better profile and nutritional value.

Comparing Latin American nutrient profile models using data from packaged foods with child-directed marketing within the Brazilian food supply.

Objectives: This study aimed to examine and compare the extent to which different nutrient profile models (NPMs) from Latin America (LA) identify packaged foods and beverages with child-directed marketing sold in Brazil as being high in nutrients associated to the risk of non-communicable diseases (NCDs). Materials and methods: In this cross-sectional study, we evaluated 3,464 foods found in the five largest Brazilian supermarkets. Child-directed marketing was coded using the International Network for Food and Obesity/NCDs Research, Monitoring and Action Support (INFORMAS) protocol. Differences in medians of sugar, saturated fats, and sodium per 100 kcal in foods, with the presence and absence of child-directed marketing, were tested using the Mann-Whitney test. We compared six NPMs in LA and examined to what extent they targeted these products using prevalence ratios. Analyses were performed overall and by the degree of food processing according to the Nova food classification. Results: We found 1,054 packages with child-directed marketing. Among these, candies, cakes and pies, sauces and creams, and sugar-sweetened beverages were significantly higher in sugar, saturated fat, and sodium per 100 kcal than products that are not targeted at children (p < 0.05). Compared with PAHO and the Mexico models, the Brazilian NPMs would allow three times more ultra-processed foods to omit warnings for sodium (p < 0.05). The Uruguayan NPM also flagged fewer ultra-processed foods high in sodium (p < 0.05). The Brazilian model also allows four times more sugar-sweetened beverages and six times more dairy drinks to omit warnings for sugar than the Mexico and PAHO models. In comparison to all other NPMs, the Brazilian model showed the worst performance in identifying baked goods as high in sodium. Chile, Uruguay, and Peru models would also target significantly less sugar-sweetened beverages and high in at least one critical nutrient than PAHO and Mexico models. Conclusion: Compared with other NPMs in LA, the NPM criteria adopted in Brazil are more permissive and less likely to inform consumers of the poor nutritional quality of ultra-processed foods and beverages with child-directed marketing.

Are Spanish Surveys Ready to Detect the Social Factors of Obesity?

The social origins of obesity are now recognised: a problem that is initially biological is today a public health problem with a social origin. This paper raises the question of whether the official statistical sources used to understand changes in diet are able to detect this shift in analysis. After reviewing the social factors that explain obesity, we examine the official Spanish statistics that can inform about dietary changes: the ENS National Health Survey, the EPF Family Budget Survey, and the EET Time Use Survey, all carried out by the Spanish Statistical Office. All of them include socio-demographic variables and some locational variables. However, the lack of health variables in the economic survey and the lack of social variables in the health survey prevent the gathering of reliable scientific evidence to offer solid support in stopping the obesity epidemic. Food has become particularly important as one of the main areas where unhealthy decisions and choices involve high risk; the situation also demonstrates the relationship between social inequality and obesity. Obesity is now understood in a radically different way and the origin of the problem lies in social and cultural factors. The current surveys do not provide the resources to capture the social causality of obesity, but slight modifications would help expand their capabilities and offer reliable scientific evidence to stop the obesity epidemic.

Dietary Effects of Introducing Salt-Reduced Bread with and without Dietary Counselling-A Cluster Randomized Controlled Trial.

Successful strategies for policy makers and the food industry are required to reduce population salt intake. A 4-month cluster randomized controlled trial was conducted to evaluate whether the provision of salt-reduced bread with or without dietary counselling affected the dietary intake of selected food groups, energy, macronutrients, sodium, and potassium. Eighty-nine families (n = 309) consisting of minimum one parent and one child were assigned to receive bread gradually reduced in salt content alone (Intervention A), combined with dietary counselling (Intervention B), or bread with regular salt content (control). Food intake was recorded for seven consecutive days at baseline and follow-up. Salt intake was reduced in both Intervention A (-1.0 g salt/10 MJ, p = 0.027) and Intervention B (-1.0 g salt/10 MJ, p = 0.026) compared to the control. Consumption of bread and both total and salt-rich bread fillings remained similar between groups, while 'cheese and cheese products' were reduced in Intervention A (-38%, p = 0.011). Energy intake and macronutrient distribution were not affected in Intervention A, but Intervention B resulted in a higher energy intake (512 kJ, p = 0.019) and a lower energy % (E%) from saturated fat (-1.0 E%, p = 0.031) compared to the control. In conclusion, provision of salt-reduced bread both with and without dietary counselling successfully reduced dietary salt intake without adversely affecting the dietary nutritional quality.

Is Information Asymmetry a Disruptive Factor in Food Consumer Behavior During the COVID Pandemic?

Today, food quality and safety, on the one hand, as well as increasing the level of information of consumers with direct implications on their food preferences, on the other hand, are highly debated topics in both national and international literature. The lack of consumers' knowledge of information on food safety could make consumers purchase unsafe food. In the event of the existence of this kind of information, the consumption would be a safer one. Our research aimed to understand the means of adjusting the food offered to the request manifested by young and educated people and the impact of the information asymmetry on the consumers' behavior. The main objectives of the study focus on exploring the nature of the informational asymmetry and the extent to which it usually affects the consumers' perception and on identifying the prevalent socioeconomic factors that influence the consumers' behavior regarding their perception of the quality of the food products and quantifying the impact of the information asymmetry on consumers' behavior. In this study, a questionnaire survey among 529 young and educated people was used to design a cumulative analysis in order to allow the forecast based on a future trend of the food policies in relation to the change in the consumers' behavior induced by the informational asymmetry. This analysis was segmented into impact sections that delineate the weight of the generating asymmetry factors from the weight of the factors with resistance to this phenomenon. The results of the survey led both to the identification of a quantification model of the information asymmetry that manifests itself within the relationship between the producer and the consumer and to the identification of a typology of informational asymmetry which manifests itself differently depending on the features of the food products. The study can be useful for those entities that want to identify the changes in the typology of consumption according to certain criteria in order to correlate their offer with the consumers' requirements, as well as for the national or regional institutional bodies with a role in developing food policies adapted to these requirements.

Benchmarking public policies to create healthy food environments compared to best practice: the Healthy Food Environment Policy Index in Guatemala.

BACKGROUND: Benchmarking the implementation of healthy food environment public policies against international best practices may accelerate the government response to prevent obesity and non-communicable diseases (NCDs) in the countries. The aim of the study was to determine the extent of food environment policy implementation in Guatemala and to identify and prioritize actions for the government to accelerate their implementation. METHODS: The INFORMAS Healthy Food Environment Policy Index (Food-EPI from the International Network for Food and Obesity/NCDs Research, Monitoring and Action Support) was used. Evidence of implementation for 50 good practice indicators within the seven food policies and six infrastructure support domains was compiled, and subsequently validated by Guatemalan government officials. A national civil society expert panel on public health and nutrition performed an online assessment of the implementation of healthy food environment policies against best international practices. The level of agreement among evaluators was measured using the Gwet second order agreement coefficient (AC2). The expert panel recommended actions for each indicator during on-site workshops and those actions were prioritized by importance and achievability. RESULTS: The expert panel rated implementation at zero for 26% of the indicators, very low for 28% of indicators, low for 42%, and medium for 4% of indicators (none were rated high). Indicators at medium implementation were related to the use of evidence for developing policies and ingredient list/nutrition information panels on packaged foods. Seventy-seven actions were recommended prioritizing the top 10 for immediate action. The Gwet AC2 was 0.73 (95% CI 0.67-0.80), indicating a good concordance among experts. CONCLUSIONS: In the Food-EPI of Guatemala, almost all indicators of good practice had a low or less level of implementation. The expert panel proposed 12 priority actions to accelerate policy implementation to tackle obesity and NCDs in the country.

Guideline Daily Amounts Versus Nutri-Score Labeling: Perceptions of Greek Consumers About Front-of-Pack Label.

Nutrition information is becoming more urgent than ever so that consumers can make informed choices when buying food. This study aimed to investigate consumers' perceptions and behavior of the front-of-pack label (FOPL), between two specific labeling systems, the Nutri-Score and the Guideline Daily Amounts (GDA). This is a post hoc analysis of data from a previous, more extensive cross-sectional study conducted from April 2021 to June 2021. A total of 510 participants were included in the study, of whom 49.6% were women. Participants' perceptions were assessed in nine questions on a five-point Likert scale (1=strongly disagree, 5=strongly agree). Multivariate variance analysis (MANOVA) was performed to test the effects of the label GDA vs. Nutri-Score on the overall positive and negative perceptions. We found that the Nutri-Score label was significantly more understandable (p=0.003), clear, visible, and preferable (p<0.001) than the GDA label, which required more time to be understood. The findings indicate that the interpretive label, Nutri-Score, was superior to the non-interpretive label GDA, in terms of consumers' perception, more visibility, less time-consuming, and reliability. The FOPL can improve the ability of consumers in Greece to understand the healthfulness of food products.

Microsimulation Modeling in Food Policy: A Scoping Review of Methodological Aspects.

Food policies for the prevention and management of diet-related noncommunicable diseases (NCDs) have been increasingly relying on microsimulation models (MSMs) to assess effectiveness. Given the increased uptake of MSMs, this review aims to provide an overview of the characteristics of MSMs that link diets with NCDs. A comprehensive review was conducted in PubMed and Web of Knowledge. Inclusion criteria were: 1) findings from an MSM; 2) diets, foods, or nutrients as the main exposure of interest; and 3) NCDs, such as overweight/obesity, type 2 diabetes, coronary heart disease, stroke, or cancer, as the disease outcome for impact assessment. This review included information from 33 studies using MSM in analyzing diet and diverse food policies on NCDs. Hereby, most models employed stochastic, discrete-time, dynamic microsimulation techniques to calculate anticipated (cost-)effectiveness of strategies based on food pricing, food reformulation, or dietary (lifestyle) interventions. Currently available models differ in the methodology used for quantifying the effect of the dietary changes on disease, and in the method for modeling the disease incidence and mortality. However, all studies provided evidence that the models were sufficiently capturing the close-to-reality situation by justifying their choice of model parameters and validating externally their modeled disease incidence and mortality with observed or predicted event data. With the increasing use of various MSMs, between-model comparisons, facilitated by open access models and good reporting practices, would be important for judging a model's accuracy, leading to continued improvement in the methodologies for developing and applying MSMs and, subsequently, a better understanding of the results by policymakers.

Prácticas y representaciones alimentarias de un grupo de mujeres en relación al uso de la tarjeta Alimentar en un barrio en situación de pobreza en Granadero Baigorria, Santa Fe / Food practices and representations of a group of women in their use of the alimentar card in a poor neighborhood in Granadero Baigorria, Santa Fe

Resumen En Argentina el 42% de la población se encuentra inmersa en la pobreza, en contextos donde los recursos sanitarios, educacionales, estructurales y alimentarios escasean. Para intentar moderar esta situación, el Estado argentino pone en marcha diferentes planes y programas sociales que procuran brindar contención a las poblaciones más desfavorecidas. Los programas alimentarios incluyen la comida que se otorga en comedores comunitarios, ayudas económicas y entregas de alimentos. Las familias que viven en un contexto de pobreza desarrollan prácticas alimentarias que les permiten sobrevivir con los escasos recursos que cuentan. En este trabajo se describen las prácticas y representaciones alimentarias de una población beneficiaria del Plan Argentina contra el Hambre en el contexto de la pandemia de covid-19, durante el año 2020. Esta investigación se llevó a cabo desde una perspectiva cualitativa. A partir de los resultados obtenidos se puede señalar que la Tarjeta Alimentar cobró un papel fundamental en la alimentación y en la economía de estas familias, ya que posibilitó la compra de alimentos que antes les significaban un mayor esfuerzo adquirir, y contribuyó a que la situación de inseguridad alimentaria en la que se encontraban no se haya profundizado aún más como consecuencia de la pandemia. El patrón alimentario de esta población se caracteriza por ser monótono y poco variado. Durante el desarrollo de esta investigación, la tarjeta se retiraba cuando el menor cumplía 7 años, desde la mirada de las mujeres entrevistadas, esta era una de las limitaciones más importante de este programa.

Abstract In Argentina, 42% of the population is immersed in poverty, in contexts where health, educational, structural and food resources are scarce. To try to moderate this situation, the Argentine State implements several social plans and programs that seek to provide support to the most disadvantaged populations. Food programs include food provided in soup kitchens, financial assistance and food deliveries. Families living in poverty develop food practices that allow them to survive on the scarce resources they have. This paper describes the food practices and representations of a beneficiary population of the Argentina Plan against Hunger in the context of the covid-19 pandemic, in 2020. This research was conducted from a qualitative perspective. From the results obtained, it can be noted that the Alimentar Card played a fundamental role in the food and economy of these families, since it made it possible for them to buy food that previously meant a greater effort to acquire, and contributed to the fact that the situation of food insecurity in which they found themselves has not deepened even more as a result of the pandemic. The eating pattern of this population is characterized by being monotonous and little varied. During the development of this research, the card was withdrawn when the child turned 7 years old and, from the perspective of the women interviewed, this was one of the most important limitations of this program.

Undervalued Spiny Monkey Orange (Strychnos spinosa Lam.): An Indigenous Fruit for Sustainable Food-Nutrition and Economic Prosperity.

Strychnos spinosa Lam. is among the top nutrient-dense indigenous fruit species that are predominant in Southern Africa. It is a highly ranked indigenous fruit based on the nutrition and sensorial properties, which make it an important food source for the marginalized rural people. On the basis of the high vitamin C, iron, and zinc content, it has the capacity to improve the food- nutrition and the socioeconomic status of individuals, especially those in the rural areas of the developing nations. The nutritional composition of Strychnos spinosa compare favorably with many of the popular fruits, such as strawberries and orange. Additionally, Strychnos spinosa has antioxidant activity similar to well-known antioxidant fruits, which keeps it in the class of the popular fruits, giving it added nutrition-health-promoting benefits. In order to improve the availability of Strychnos spinosa, more research on the domestication, processing, preservation, value chain, and economic potential need to be further explored. Therefore, we recommend more concerted efforts from relevant stakeholders with interest in Strychnos spinosa fruit production as a possible sustainable solution to food shortage, food-nutrition insecurity, malnutrition, and austerity, mainly in the rural communities of the developing countries.

Increasing trends in obesity prevalence from 2013 to 2019 and associated factors in Brazil / Aumento nas prevalências de obesidade entre 2013 e 2019 e fatores associados no Brasil

Objective: To investigate the variation of anthropometric indicators from 2013 to 2019 and the factors associated with obesity in Brazil, using information from the National Health Survey. Methods: Cross-sectional study with cluster sampling and simple random sampling in the three stages. Measurements of weight and height among participants in 2013 (n=59,592) and in 2019 (n=6.672) were used. Differences in obesity prevalence were tested by Student's t test for independent samples. To identify the sociodemographic factors and health problems associated with obesity, we used Poisson regression models with robust variance and crude and age-adjusted prevalence ratios (PR) to test the associations.  Results: From 2013 to 2019, prevalence of obesity increased significantly, from 20.8% to 25.9%. Among men, the greatest increases were found in the 40-59 age group (9.1%) and in the median income category (8.3%). Among women, the greatest rises were found among those with low education (8.7%) and non-white ones (6.0%). For both males and females, factors associated with obesity were age, to live with a partner, level of instruction directly associated among men, and inversely associated among women. In 2019, for males, the crude and adjusted PRs were significant for high cholesterol, high blood pressure and at least one chronic non-communicable disease (NCD) and, for females, for poor self-rated health, high blood pressure, diabetes, and at least one NCD. Conclusion: It is necessary to implement intersectoral policies to promote changes in eating habits and encourage the practice of physical activity, taking into account economic, social, cultural, and environmental aspects.

Objetivo: Investigar as variações de indicadores antropométricos entre 2013 e 2019 e os fatores associados à obesidade no Brasil, utilizando as informações da Pesquisa Nacional de Saúde. Métodos: Estudo transversal com amostra por conglomerados e seleção aleatória simples nos 3 estágios. Foram usadas as medidas aferidas de peso e altura em 2013 (n=59.592) e em 2019 (n=6.672). As diferenças nas prevalências de obesidade entre 2013 e 2019 foram testadas pelo teste t de Student para amostras independentes. Para identificar os fatores sociodemográficos e problemas de saúde associados à obesidade, foram usados modelos de regressão de Poisson com variância robusta e razões de prevalência (RP) brutas e ajustadas por faixa etária para testar as associações. Resultados: De 2013 a 2019, a prevalência de obesidade aumentou significativamente, de 20,8% para 25,9%.  Entre os homens, os maiores aumentos ocorreram no grupo etário 40-59 anos (9,1%) e faixa de renda mediana (8,3%) e, entre as mulheres de baixa escolaridade (8,7%) e não brancas (6,0%).  Para ambos os sexos, os fatores associados à obesidade foram idade, viver com companheiro e escolaridade, diretamente entre homens e inversamente entre mulheres. Em 2019, para o sexo masculino, as RP brutas e ajustadas foram significativas para colesterol alto, hipertensão arterial e alguma doença crônica não transmissível (DCNT) e, para o feminino, para autoavaliação de saúde não boa, hipertensão arterial, diabetes, alguma DCNT. Conclusão: É preciso implementar políticas intersetoriais para promover mudanças nos hábitos de alimentação e incentivar a prática de atividade física, levando em consideração os aspectos econômicos, sociais, culturais e ambientais. 

Contribution of reformulation, product renewal, and changes in consumer behavior to the reduction of salt intakes in the UK population between 2008/2009 and 2016/2017.

BACKGROUND: The UK salt reduction program started in 2003, consisting of education campaigns to raise awareness about the risks associated with a high-salt diet and of a reformulation strategy for food manufacturers. This program is often cited as an example of a successful public health program. OBJECTIVES: This study aimed to assess: 1) the impacts of changes in food composition and changes in consumer behavior on sodium intakes; and 2) whether changes were similar across socioeconomic groups. METHODS: Food intakes for the UK population were derived from food diaries in the UK National Diet and Nutrition Survey for 2008/09 (year 1; n = 1334) and 2016/17 (year 9; n = 995). Year-specific sodium densities of foods were used to calculate the average sodium density of all food and beverage consumed. Changes in sodium density between the 2 years were explained by changes in food composition (change in sodium density of products) and/or changes in behavior (type and quantity of food consumed) using a decomposition approach. RESULTS: The program was linked to a 16% (95% CI: -21% to -12%) decrease in sodium intake between years 1 and 9, while the sodium density of foods consumed decreased by 17% (95% CI: -21% to -12%). This decrease was largely driven by reformulation (-12.0 mg/100 g). Changes in food choices reinforced the effects of the program, but had a smaller impact (-1.6 mg/100 g). These effects were similar across socioeconomic groups, whether stratified by education or income, with a consistent effect of reformulation across groups and no differences between groups in behavioral responses to the program. CONCLUSIONS: A multi-component sodium reduction strategy deployed in the United Kingdom starting in 2003 corresponded to an important reduction in sodium intakes for the population. This reduction was mostly driven by changes in the food environment (reformulated food products to reduce the sodium density of foods) and, to a smaller extent, by changes in food choices. Impacts were consistent across socioeconomic groups.

Assessing the effects of autarchic policies on the biological well-being: Analysis of deviations in cohort male height in the Valencian Community (Spain) during Francoist regime.

This article aims to assess the impact of autarchic policies on the biological dimensions of human well-being during Francoist regime in Spain. This is done by examining the nutritional status of the population through the study of male adult heights. Our case study is the Valencian Community with the focus on the period 1940-59 which witnessed the implementation of such policies. The heights of 21-year old draftees born between 1900 and 1954 from nine municipalities (N = 87,510) were analyzed in the light of inter-cohort deviations from a secular trend established for cohorts that were not exposed to autarchy-related hardships. Height was regressed on infant mortality as a way to control for infection and therefore approach the net effect of nutrition on height outcomes. Contrarily to what was displayed by cohort height trends in themselves, the results reveal a significant worsening of the nutritional status of the male population at the time. Deviations from the expected height trend across municipalities ranged between -0.5 and -3.4 mm per year. The effects of malnutrition are found to be larger among cohorts born in the period 1920-34 in coherence with a longer exposure to autarchy hardships during adolescence. Pre-autarchy nutrition levels observed among the cohorts of 1900-14 were not regained until the cohorts 1945-49. The results also show that malnutrition had an unequal impact with the large industrial towns of our sample experiencing the poorest height outcomes. Overall, these results invite to revise conclusions obtained from the sole evidence of height trends and they question the efficiency of intervention policies implemented in Spain during the 1940s.

Emerging responses to the COVID-19 crisis from family farming and the agroecology movement in Latin America - A rediscovery of food, farmers and collective action.

CONTEXT: In Latin America, the so-called informal sector associated with family farming and the agroecology movements were instrumental at coping with and adapting to the COVID-19 challenges. OBJECTIVE: To assess the nature and extent of the early initiatives (first three months) deployed by this informal sector to cope with and adapt to the impacts of the COVID-19 pandemic on food production and consumption in several countries of the region. METHODS: We used key used informant consultation (n = 168), an online survey (n = 125) and the detailed characterisation of regional case studies (n = 4). Textual data was analysed and categorised using Reinert's method, combined with similarity analysis. RESULTS AND CONCLUSIONS: 65% of the initiatives were 'local' in terms of geographic reach, 30% of them started within the first month after the pandemic and most of them were urban or urban-rural, whereas only 29% of them were exclusively rural. The analysis of the textual information captured through the survey revealed four major types of initiatives that were deployed or adapted in response to COVID-19:1.Direct producer-to-consumer food sales, generally existing before the COVID-19 crisis but adapted/strengthened to cope with it;2.Short value chains that linked rural and urban organisations and individuals supported by national or local governments, readapted through new health and safety protocols;3.Newly developed support and training programs on sustainable food production for self-consumption or local commerce, in rural, urban or peri-urban settings;4.Food assistance and aid initiatives focusing on vulnerable populations, relying on solidarity networks associated with the agroecological movement. SIGNIFICANCE: The pandemic highlighted the key role played by local food systems and value chains and the need to strengthening them through public policies, as a way to build food resilience in times of crisis.
