RESUMO

BACKGROUND: School meals represent a significant supply of nutrients for children in Brazil, especially those in conditions of social vulnerability. OBJECTIVES: This study aimed to assess the levels of arsenic (As), cadmium (Cd), and lead (Pb) in meals served in public elementary schools in four municipalities in the state of Bahia, Brazil, and assess the risk posed to children's health. METHODS: Ninety-six samples were collected from 16 schools, freeze-dried, and subjected to microwave-assisted digestion. The As, Cd, and Pb levels were determined by graphite furnace atomic absorption spectrometry. The risk assessment was based on calculating each element's hazard quotient (HQ). RESULTS: None of the samples reached or exceeded the tolerable levels for the elements analyzed. Pb was the metal that obtained the most significant result, reaching maximum levels of 39-157 µg·kg-1. CONCLUSIONS: No element exceeded the PTWI proposed by JECFA; thus, the toxic metal content in school meals poses a negligible risk to children's health.

RESUMO

The link between school feeding programmes (SFP) and the promotion of healthy eating and health is being explored in studies performed in different countries. The coronavirus disease-19 pandemic has revealed flaws and weaknesses in contemporary food systems, with many school-age children experiencing food insecurity and hunger. There is intense debate among policymakers regarding whether government SFP should be universal or targeted. Countries such as Brazil and India, which have two of the most comprehensive universal free-of-charge programmes, have shown the benefits of SFP, including improved nutritional status, support for more sustainable food systems, attendance and academic performance. Evidence shows and supports actions advocating that it is time to offer healthy and free school meals for all students.

RESUMO

BACKGROUND: One of the reasons for the more prominent resistance of canteen managers to implementing healthy canteens is based on the belief in the economic infeasibility of these models. The research aimed to verify the economic and financial viability of traditional and healthy models of school canteens in a Brazilian metropolis. METHODS: The case study was carried out with 36 companies in the school canteen sector in a Brazilian metropolis. The classification of items sold in canteens considered the extent and purpose of food processing according to the NOVA Classification. The characterization and definition of traditional canteens and healthy canteens were proposed considering the amount of in natura or minimally processed foods and culinary preparations without the presence of ultra-processed foods; the percentage of ultra-processed foods or processed foods or culinary preparations with the presence of ultra-processed foods; and the existence of prohibited foods. The economic and financial analysis was carried out mainly through the evaluation of profitability. Data were collected through an electronic self-administered questionnaire sent to canteen managers. The Mann-Whitney test was used to compare medians and the Chi-Square/Fisher's Exact Test to compare proportions. RESULTS: The study included six companies, responsible for 36 canteen units in private schools, 30 classified in the traditional model (83.3%), and six in the healthy model (16.7%). The median percentage of natural, minimally processed foods and commercialized culinary preparations was higher among the healthy model canteens (87.9% vs. 60.0%, p < 0.001). While the median percentage of ultra-processed, processed, or preparations with the presence of ultra-processed (40.0% vs. 12.1%, p < 0.001) and prohibited foods (10.0% vs. 0%, p < 0.001) sold was higher in the traditional model canteens. The results indicated that the profitability in the healthy canteens was higher (p < 0.001) than in the traditional ones. CONCLUSIONS: Healthy school canteens showed better financial and economic results compared to traditional canteens with emphasis on greater profitability and a shorter recovery time of the initial investment.

RESUMO

Resumo Este trabalho busca apreender os desafios que perpassam o processo, em curso, de inserção de alimentos da sociobiodiversidade na alimentação escolar, no município de Mostardas, no Rio Grande do Sul, bem como analisar os possíveis resultados desse movimento in loco. A respeito do percurso metodológico, em decorrência do contexto pandêmico de covid-19, foram realizadas entrevistas por telefone e/ou pelo aplicativo WhatsApp© com atores que tivessem, de algum modo, envolvimento no processo de inclusão de alimentos da sociobiodiversidade no Programa Nacional de Alimentação Escolar, como nutricionistas, comunidade escolar, entidades locais, agricultores(as) familiares e pesquisadores(as). Assim, recorreu-se à abordagem qualitativa, tanto para a geração do material empírico quanto para a análise dos dados. Acerca dos resultados, foram identificados desafios relacionados ao plano da produção, do consumo e do abastecimento. E, ainda, no âmbito das políticas públicas, foram constatados entraves relacionados ao acesso a determinados programas federais, burocracia dos processos e falta de iniciativas por parte do poder público local. Com relação aos possíveis desdobramentos do movimento em questão, os participantes manifestaram repercussões sobre a saúde, a qualidade da alimentação, o meio ambiente e a economia local, o que impactaria positivamente sobre a Soberania e a Segurança Alimentar e Nutricional.

Abstract This work seeks to understand the challenges that permeate the ongoing process of inserting sociobiodiversity foods into school meals, in the municipality of Mostardas, Rio Grande do Sul, and to analyze the possible results of this movement in loco. Regarding the methodological course, due to the covid-19 pandemic context, interviews were carried out by phone call and/or by the WhatsApp© application with actors who were somehow involved with the process of inclusion of sociobiodiversity foods in the National School Feeding Program, such as nutritionists, the school community, local entities, family farmers, and researchers. Thus, a qualitative approach was used, both for the generation of empirical material and for data analysis. Regarding the results, challenges related to the production, consumption, and supply plan were identified. And yet, in the scope of public policies, obstacles related to access to certain federal programs, bureaucracy of processes, and lack of initiatives on the part of the local government were found. Regarding the possible developments of the movement in question, the participants expressed repercussions on health, food quality, the environment, and the local economy, which would positively impact Food and Nutrition Sovereignty and Security.

RESUMO

Introdução: Os instrumentos e estratégias de Educação Alimentar e Nutricional de escolas públicas brasileiras devem apoiar pessoas, famílias e comunidades a adotarem práticas alimentares que favoreçam o desenvolvimento da autonomia e do exercício da cidadania. Objetivo: Compreender como escolas e famílias, a partir de suas ações conjuntas, podem favorecer a promoção da alimentação adequada e saudável. Métodos: Pesquisa de natureza qualitativa, na modalidade de estudo de caso, realizada em duas escolas públicas de ensino fundamental, que incluíram no Projeto Político-Pedagógico ações de alimentação e a participação das famílias. Utilizaram-se observação participante, diário de campo, entrevistas semiestruturadas e grupos focais com os membros da comunidade, analisados por triangulação de métodos qualitativos. Para as entrevistas e grupos focais, foram feitas transcrição, categorização e análise temática de conteúdo. Resultados: As categorias temáticas "Interação entre os atores sociais" e "Participação das famílias no espaço escolar" mostraram as possibilidades de ações conjuntas no papel coletivo de educadores. A organização da comunidade em grupos de responsabilidade conferiu sentido à participação social, rompeu com o suposto desinteresse pelas ações de alimentação e viabilizou a atuação nos processos decisórios da escola. Como desafios, têm-se a desconfiança recíproca e a dificuldade de promover reflexão coletiva para solucionar conflitos e disputas. Conclusões: O estabelecimento de parcerias bem-sucedidas entre escola e família coloca crianças e adolescentes no centro do debate, alusiva à função coletiva de todos como educadores, explorando características individuais e coletivas para as ações promotoras da alimentação adequada e saudável.

Introduction: Food and Nutrition Education resources and strategies in Brazilian public schools should support people, families, and communities to adopt eating practices that benefit the development of autonomy and the exercise of citizenship. Objective: To understand how schools and families, through their joint actions, can promote adequate and healthy eating. Methods: This is qualitative research carried out in two public elementary schools, which have included foodprograms and family participation in their Political-Pedagogical Project. Participant observation, field journals, semi-structured interviews, and focus groups with community members were used and analyzed using a triangulation of qualitative methods. For the interviews and focus groups, transcription, categorization, and thematic content, analysis were carried out. Results: The thematic categories "Interaction between social actors" and "Participation of families in the school space" showed the possibilities of joint actions in the collective role of educators. The organization of the community into responsibility groups gave meaning to social participation, broke down the supposed lack of interest in food actions and made it possible for them to take part in the school's decision-making processes. The challenges are mutual distrust and the difficulty of promoting collective reflection to resolve conflicts and disputes. Conclusions: Establishing successful school-family partnerships puts children and adolescents at the center of the debate, alluding to everyone's collective role as educators, exploiting individual and collective characteristics for actions to promote adequate and healthy eating.

RESUMO

Introdução: As Conferências Nacionais de Segurança Alimentar e Nutricional (CNSAN) foram realizadas no Brasil no período de 1994 a 2015. Por seu caráter intersetorial e multidimensional, as CNSAN debateram um amplo conjunto de temas e recomendações de políticas e programas, dentre eles, o Programa Nacional de Alimentação Escolar (PNAE). Objetivo: Analisar as repercussões das recomendações das CNSAN direcionadas ao PNAE no processo legislativo. Métodos: Trata-se de estudo documental, realizado em duas fases: a primeira consistiu na identificação de recomendações para políticas públicas de SAN contempladas nos relatórios das cinco CNSAN direcionadas ao PNAE; a segunda, na busca de projetos legislativos que tivessem pertinência temática com as demandas das CNSAN no período de 24 meses após cada evento. Resultados: Identificou-se, nas CNSAN, um total de 24 recomendações para atualização do PNAE e 24 projetos legislativos que tratam integral ou parcialmente dos temas e se distribuem de forma desigual entre as CNSAN. Foram encontrados projetos legislativos para 41,7% das recomendações das CNSAN para o PNAE, indicando que há convergência entre a agenda das CNSAN e do Legislativo brasileiro; as recomendações de universalização do programa e de reajuste dos valores repassados pela União para estados e municípios sobressaíram quanto ao número de projetos no Legislativo, indicando foco na garantia do direito à alimentação escolar; duas leis foram aprovadas para o período estudado. Conclusão: Tais resultados podem estar relacionados à abertura do congresso para as recomendações das CNSAN, devido ao modelo de governança adotado no período analisado.

Introduction: The National Food and Nutrition Security Conferences (from Portuguese: Conferências Nacionais de Segurança Alimentar e Nutricional (CNSAN), were held in Brazil from 1994 to 2015. Due to its intersectoral and multidimensional nature, the CNSAN debated a wide range of themes, policy and program recommendations, among it, the National School Feeding Program (from Portuguese: Programa Nacional de Alimentação Escolar (PNAE)). Objective: To analyze the repercussions of CNSAN recommendations directed to PNAE in the legislative process. Methods: This is a documentary study, carried out in two phases: the first consisted of identifying recommendations for public policies included in the reports of the five CNSAN directed to the PNAE; the second, in the search for legislative projects that had thematic relevance with the demands of CNSAN in the 24-month period after each event. Results: A total of 24 recommendations for updating the PNAE and 24 legislative projects were identified in the CNSAN, which fully or partially address the topics and are unevenly distributed among it. Legislative projects were found for 41.7% of the CNSAN recommendations for the PNAE, indicating that there is convergence between the CNSAN agenda and the Brazilian Legislature; the recommendations for universalizing the program and readjusting the amounts transferred by the Union to states and municipalities stood out in terms of the number of projects in the Legislature, indicating a focus on guaranteeing the right to school meals; two laws were approved for the period studied. Conclusion: The results may be related to the opening of the congress to the CNSAN recommendations, due to the governance model adopted in the period analyzed.

RESUMO

Abstract Objectives: this review aimed to evaluate the adequacy of school menus regarding the nutritional requirements of the Programa Nacional de Alimentação Escolar (PNAE) in Brazilian public schools regarding the presence of macronutrients and micronutrients and allocation of resources to purchase products from family farming. Methods: a systematic literature review was carried out using the SciELO, Bireme and Lilacs databases to select the articles. The inclusion criteria were articles that presented data on the adequacy of energy, macronutrients, micronutrients, and purchases of products from family farming during the PNAE regiment, as well as quantitative, cross-sectional, and descriptive studies carried out in the Brazilian territory. Review, editorials, letters, case studies, duplicates and those that did not assess the requirements of the PNAE were excluded. Results: at the end, 12 studies were included that showed overestimation and underestimation of nutritional adequacy in the school environment. In relation to purchases of inputs from family farming, it was observed that most of the Brazilian municipalities evaluated fulfilled the requirements for the allocation of resources. Conclusion: school menus need more supervision so that they meet the adjustments proposed by the PNAE. In addition, it is essential to promote a healthy diet that contains all the nutrients necessary to provide nutritional support for child growth and development.

Resumo Objetivo: avaliar a adequação dos cardápios escolares quanto às exigências nutricionais do Programa Nacional de Alimentação Escolar (PNAE) em escolas públicas brasileiras considerando quanto a adequação de macronutrientes e micronutrientes e destinação de recursos para compras de produtos advindos da agricultura familiar. Métodos: foi realizada uma revisão sistemática da literatura utilizando as bases de dados SciELO, Bireme e Lilacs para seleção dos artigos. Os critérios de inclusão foram: Artigos que apresentaram dados sobre a adequação de energia, macronutrientes, micronutrientes e compras de produtos oriundos da agricultura familiar durante o regimento do PNAE, assim como estudos quantitativos, transversais e descritivos realizados no território brasileiro. Foram excluídos artigos de revisão, editoriais, cartas ao editor, estudos de caso, artigos em duplicatas e que não avaliaram as exigências do PNAE. Resultados: ao final, foram incluídos12 estudos que apontaram superestimação e subestimação nas adequações nutricionais no ambiente escolar. Em relação às compras de insumo provenientes da agricultura familiar, observou-se que a maioria dos municípios brasileiros avaliados cumpriam as exigências de destinação dos recursos. Conclusões: os cardápios escolares necessitam de maior fiscalização para que atendam as adequações propostas pelo PNAE. Além disso, é primordial promover uma alimentação saudável que contenha todos os nutrientes necessários para fornecer um aporte nutricional para o crescimento e desenvolvimento infantil.

RESUMO

Aimed at improving the quality of school meals, the Sustainable School Program (SSP) implemented low-carbon meals, twice a week, in 155 schools of 4 municipalities, reaching more than 32,000 students. This study evaluated the environmental impact and nutritional viability of this intervention for this population. The 15 most repeated meals from the conventional and sustainable menus were selected, and we considered the school age group and number of meals served per student/day. Nutritional information was calculated using validated food composition tables, nutritional adequacy was assessed using National School Feeding Program (PNAE) requirements, the level of processing was considered using NOVA classification, and greenhouse gas emissions (GHGE) were estimated using food life cycle assessment (LCA) validated data. We found both conventional and sustainable food menus are equivalent, in terms of nutrients, except for calcium, iron, and magnesium. Sustainable food menus were cholesterol-free. However, there was a reduction of up to 17% in GHGE, depending on the school age group analysed. Considering the greater energy efficiency and lower environmental impact of these food menus, the SSP, therefore, demonstrates that a substantial reduction in climate impact is feasible, successful, and can be an inspiration to other regions globally.

RESUMO

Considering the importance of schools for sustainable food offers and the formation of conscientious citizens on sustainability, this systematic review aimed to verify the recommendations on sustainability in school feeding policies and the sustainability practices adopted in schools. The research question that guided this study is "what are the recommendations on sustainability in school feeding policies and the sustainability practices adopted in schools?". This systematic review was prepared according to PRISMA, and its checklist was registered in PROSPERO. Specific search strategies for Scopus, Web of Science, Pubmed, Lilacs, Google Scholar, and ProQuest Dissertations & Theses Global were developed. The included studies' methodological quality was evaluated using the Meta-Analysis Statistical Assessment and Review Instrument (MASTARI). A total of 134 studies were selected for a full reading. Of these, 50 met the eligibility criteria and were included in the systematic review. Several sustainability practices were described. The most cited are school gardens and education activities for sustainability. However, actions carried out in food services were also mentioned, from the planning of menus and the purchase of raw materials (mainly local and organic foods, vegetarian/vegan menus) to the distribution of meals (reduction of organic and inorganic waste: composting, recycling, donating food, and portion sizes). Recommendations for purchasing sustainable food (organic, local, and seasonal), nutrition education focused on sustainability, and reducing food waste were frequent; this reinforces the need to stimulate managers' view, in their most varied spheres, for the priority that should be given to this theme, so that education for sustainability is universally part of the curricula. The importance of education in enabling individuals to promote sustainable development is reaffirmed in Sustainable Development Goal 4 (SDG 4). The development of assessment instruments can help monitor the evolution of sustainable strategies at schools and the main barriers and potentialities related to their implementation.

RESUMO

OBJECTIVES: This study aimed to analyze the relationship between food insecurity and school meal consumption, adjusted for sociodemographic variables. METHODS: This cross-sectional study investigated households with children and adolescents living in Brazilian municipalities. A semistructured survey was administered to parents/guardians at a parent-teacher meeting to assess their socioeconomic conditions and access to food, using the Brazilian Food Insecurity Scale to classify households as having food security or mild, moderate, or severe food insecurity. Parents and students were asked about the frequency of their consumption of school meals offered by the Brazilian School Food Program, which is one of the largest public policies in Brazil and offers free meals to all students in all public schools. Multinomial regression was performed to assess the relationship between food security and frequency of school meal consumption. RESULTS: A total of 1705 students participated in the study, most of whom displayed some degree of food insecurity (56.5%) per the Brazilian Food Insecurity Scale. Regular consumption of school meals (>3 times/wk) was reported by 78.5% of students. Regarding the frequency of school meal consumption adjusted by sociodemographic variables, students from households with food insecurity (moderate or severe) were more likely to regularly consume school meals. The prevalence of households with moderate or severe food insecurity was twice as high as for those who lived in households with food security after adjusting for sociodemographic variables (odds ratio: 2.35; 95% confidence interval 1.53-3.61). CONCLUSIONS: The Brazilian School Food Program has contributed greatly to food security. Although the guarantee of universality is essential for the program to reach all school children who are experiencing food insecurity, the program should also aim for greater equity.

RESUMO

O Programa Nacional de Alimentação Escolar possui papel fundamental na promoção da alimentação saudável de milhões de escolares em todo o Brasil. Entretanto, pesquisas nacionais apontam baixa adesão e aceitabilidade à alimentação escolar na rede pública de ensino. Intervenções baseadas em arquitetura de escolhas e padronização de técnicas gastronômicas têm sido implementadas com o intuito de melhorar este cenário e estimular o desenvolvimento de hábitos alimentares saudáveis. Assim, o objetivo do presente estudo foi avaliar a efetividade de intervenção multicomponente na adesão e aceitabilidade à alimentação escolar. Um ensaio randomizado foi conduzido com alunos do 4o ao 9o ano de 3 escolas públicas da rede municipal de ensino da cidade de Sumidouro, Rio de Janeiro, em 2019. As escolas participantes foram alocadas aleatoriamente em três grupos: uma escola no grupo controle (sem intervenção), uma escola no grupo intervenção 1 (modificações ambientais e inclusão de sistema de autosserviço) e uma escola no grupo intervenção 2 (modificações ambientais, inclusão de sistema de autosserviço e adição de novas preparações no cardápio). A escola do grupo intervenção 1 recebeu intervenções ambientais baseadas nos princípios da arquitetura de escolhas, que consistiram em: elaboração de cartazes e displays com mensagens e imagens motivacionais para promoção de hábitos alimentares saudáveis e incentivo ao consumo da alimentação escolar; implementação de toalhas com imagens coloridas de alimentos in natura nas mesas do refeitório; alocação das frutas servidas na alimentação escolar em posição de destaque, em uma barraca de frutas; posicionamento de um banner com o cardápio das preparações diárias na entrada do refeitório; e aplicação de pegadas no chão que, de forma lúdica, direcionavam os escolares ao refeitório. Além disso, foi implementado o sistema de autosserviço, com a incorporação de um balcão térmico de distribuição de alimentos no refeitório. A escola do grupo intervenção 2 recebeu as mesmas intervenções da escola do grupo intervenção 1, com a adição da padronização de técnicas gastronômicas para alterações nas preparações culinárias que fizeram parte dos cardápios no ano letivo de 2019, além da elaboração de novas preparações a partir da identificação das percepções acerca dos motivos da não adesão à alimentação escolar relatadas em grupos focais realizados com merendeiras e escolares. A adesão à alimentação escolar (≥3 vezes na semana) foi avaliada por meio de questão inserida em questionário aplicado em três momentos (linha de base, 1o seguimento [após 5 meses de intervenção] e 2o seguimento [após 8 meses de intervenção]). Foram realizadas análises longitudinais por meio da aplicação de modelos lineares generalizados que levam em conta as medidas repetidas e os dados ausentes de desfecho dos participantes. Também foram realizadas análises do tipo piecewise, permitindo a identificação dos parâmetros no intervalo 1 (linha de base-1o seguimento) e no intervalo 2 (1o seguimento-2o seguimento). Foi observado aumento da adesão à alimentação escolar na escola intervenção 1 vs. escola controle (RR=1,20; p-valor=0,0166) e maior aumento na escola intervenção 2 vs. escola controle (RR=1,27; p-valor=0,0041). Foi possível observar também aumento da adesão na escola intervenção 1 vs. escola controle no intervalo 1 e intervalo 2 (RR=1,18; p-valor=0,0146 e RR=1,14; p-valor=0,0424, respectivamente), e maior aumento da adesão na escola intervenção 2 vs. escola controle no intervalo 1 (RR=1,22; p-valor=0,0095) e no intervalo 2 (RR=1,20; p-valor=0,0070). Não houve diferença estatisticamente significativa na variação da adesão entre as escolas intervenção 2 e 1. A aceitabilidade à alimentação escolar foi avaliada por meio da aplicação de teste de aceitabilidade referente ao cardápio servido nas escolas antes das intervenções e, aos demais cardápios, após o início das intervenções, através do uso da escala hedônica facial e verbal. Para as análises longitudinais, foram empregados modelos lineares generalizados, que levam em conta as medidas repetidas e os dados ausentes de desfecho dos participantes. Observou-se aumento significativo no índice de aceitabilidade nos grupos de preparações à base de carne bovina e doces entre os participantes da escola intervenção 1 (RR=1,36; p-valor=0,0008 e RR=3,99; p-valor=<,0001, respectivamente) e da escola intervenção 2 (RR=1,34; p-valor=0,0029 e RR=2,22; p-valor=<,0001, respectivamente), quando comparados aos da escola controle ao longo do tempo. O incremento na aceitabilidade das frutas foi maior entre os participantes da escola intervenção 2, quando comparados aos da escola intervenção 1 (RR=1,60; p-valor=0,0052). Redução da aceitabilidade de preparações à base de feijão foi observada entre escola intervenção 2 e as escolas intervenção 1 e controle (RR=0,60; p-valor=0,0003 e RR=0,57; p-valor=0,0013, respectivamente). Os resultados alcançados sugerem que intervenções multicomponentes baseadas em modificações ambientais de baixo custo e complexidade, e em modificações nos aspectos sensoriais das refeições oferecidas na alimentação escolar através da inserção de técnicas gastronômicas, podem ser efetivas para promover o aumento da adesão e aceitabilidade à alimentação escolar e, consequentemente, auxiliar na elaboração de políticas públicas voltadas à promoção da alimentação saudável.

The National School Feeding Program plays a key role in promoting healthy eating for millions of schoolchildren throughout Brazil. However, national surveys indicate low adherence and acceptability to school meals in the public school system. Interventions based on choices architecture and standardization of gastronomic techniques have been implemented aiming to improve this scenario and encourage the development of healthy eating habits. Thus, the objective of this study was to evaluate the effectiveness of a multicomponent intervention in adherence and acceptability to school meals. A randomized trial was conducted with students from 4th to 9th grade from 3 public schools of Sumidouro, a city located in Rio de Janeiro, in 2019. The participating schools were randomly allocated into three groups: one school in the control group (no intervention), another school in the intervention group 1 (environmental modifications and addition of a self-service system) and other one in the intervention group 2 (environmental modifications, addition of a self-service system and inclusion of new dishes in the menu). The school from the intervention group 1 received environmental interventions based on the principles of choices architecture, which consisted of: creation of posters and displays with motivational messages and images to promote healthy eating habits and encourage the consumption of school meals; implementation of tablecloth with colorful images of fresh food on the cafeteria tables; allocation of fruits in a prominent position, in a fruit stand; placement of a banner with the daily menu at the cafeteria's entrance; and application of footprints on the floor that, in a playful way, directed students to the cafeteria. Moreover, a self-service system was implemented through the addition of a thermal food distribution counter in the cafeteria. The school from intervention group 2 received the same interventions as the school from intervention group 1, plus the standardization of gastronomic techniques for changes in the dishes that were part of the menus in 2019, and also the creation of new ones, based on the perceptions about the reasons for non-adherence to school meals reported in focus groups carried out with lunch ladies and schoolchildren. Adherence to school meals (≥3 times a week) was assessed through a question inserted in a questionnaire applied at three different moments (baseline, 1st follow-up [after 5 months of intervention] and 2nd follow-up [after 8 months of intervention]). Longitudinal analyzes were performed through the application of generalized linear models that take into account repeated measures and missing participant outcome data. Piecewise analyzes were also performed, allowing the identification of parameters in interval 1 (baseline - 1st follow-up) and in interval 2 (1st follow-up - 2nd follow-up). An increase in adherence to school meals was observed in the intervention school 1 vs. control school (RR=1.20; p-value=0.0166) and greater increase in intervention school 2 vs. control school (RR=1.27; p-value=0.0041). It was also observed an increase in adherence in the intervention school 1 vs. control school in interval 1 and interval 2 (RR=1.18; p-value=0.0146 and RR=1.14; p-value=0.0424, respectively), and greater increase in adherence in intervention school 2 vs. control school in interval 1 (RR=1.22; p-value=0.0095) and in interval 2 (RR=1.20; p-value=0.0070). There was no statistically significant difference in the variation of adherence between intervention 2 and 1 schools. The acceptability of school meals was evaluated by applying an acceptability test referring to the menu served in schools before the interventions and, to the other menus, after the beginning of the interventions, through the use of facial and verbal hedonic scale. For the longitudinal analyses, generalized linear models were used, taking into account repeated measures and missing outcome data from the participants. There was a significant increase in the acceptability index in the groups of preparations based on meat and sweets among participants in the intervention school 1 (RR=1.36; p-value=0.0008 and RR=3.99; p- value=<.0001, respectively) and intervention school 2 (RR=1.34; p-value=0.0029 and RR=2.22; p-value=<.0001, respectively), when compared to the control school over time. The increase in fruit acceptability was greater among participants in the intervention school 2, when compared to those in the intervention school 1 (RR=1.60; p-value=0.0052). Reduction in the acceptability of bean-based preparations was observed between intervention 2 school and intervention 1 and control schools (RR=0.60; p-value=0.0003 and RR=0.57; p-value=0.0013, respectively). The results suggest that multicomponent interventions based on low cost and complexity environmental modifications, and also on changes in the sensory aspects of meals offered at school through the use of gastronomic techniques, can be effective in increasing adherence and acceptability to school meals, assisting in the creation of public policies aimed at promoting healthy eating.

RESUMO

Access, nutritional characteristics, preferences, and cost can affect food intake at school. A cross-sectional study was performed to determine the nutritional characteristics, sites of origin, and cost of foods consumed during school hours. Three hundred and sixty-nine children from five public elementary schools in Mexico City participated. The children gave information about the foods that they consumed five days out of the week during school hours, including the place of acquisition, cost of the food, and portion size. Anthropometric measurements of height and weight of the children were taken. Caloric consumption and percentage of recommended daily energy intake from food during school hours was determined. Children were 10.9 ± 0.9 years old; 55.6% were girls, 26% were overweight, 23% were obese, and 3.3% were of low height for age. The average calorie intake was 515 kilocalories (kcal) (boys, 535 kcal; girls, 476 kcal, p = 0.051); calorie intake was higher when school meal intakes included foods from home, school, and outside of school. No significant differences were found in calorie intake by children's nutritional status. The cost in Mexican pesos per 100 kcal consumed showed differences according to the nutritional status of the children; it was 4.0 Mexican pesos for children with normal weight and 4.2 and 3.8 pesos in children who were overweight or obese, respectively. The information obtained in this study should be used to provide nutritional guidance. The food portion size intake during school hours should be reduced, and the food should come from one or at most two sites, because each extra food represents an increase in the total kilocalorie intake.

RESUMO

Introdução: A alimentação escolar é a principal ou a única refeição do dia para grande parte dos estudantes brasileiros. Em decorrência da Covid-19, foi decretado estado de emergência e foram interrompidas as aulas na rede pública de ensino, colocando de forma necessária cerca de 40 milhões de estudantes sem aulas presenciais. Objetivos: Verificar as principais ações dos estados e do Distrito Federal em relação à alimentação escolar durante a pandemia e se as mesmas estão condizentes a Lei Federal nº 13.987/2020. Métodos: Foi realizada revisão narrativa da literatura, utilizando-se informações sobre as principais ações realizadas pelos estados e Distrito Federal, advindas de reportagens, boletins oficiais, homepages do Ministério da Educação, decretos e/ou portarias estaduais, entre março e maio de 2020. Resultados e Discussão: As principais ações que todos os 26 estados brasileiros e o Distrito Federal realizaram durante a suspensão das aulas foram díspares: seis estados brasileiros optaram pela transferência direta de renda; nove distribuíram kits de alimentos, sendo que cinco incluíram itens de agricultura familiar; e o Distrito Federal realizou as duas modalidades supracitadas. Destaca-se que tais ações foram focalizadas nas famílias beneficiárias do Programa Bolsa Família. Ademais, em determinados estados, não foi considerada a compra de no mínimo 30% da agricultura familiar. Conclusão: Apesar de todos os estados e o Distrito Federal terem agido para preservar o direito à alimentação escolar dos estudantes da rede pública de ensino, observou-se que tais ações foram heterogêneas e não condizentes com a Lei Federal nº 13.987/2020.

Introduction: School meals are the main or only meal of the day for most Brazilian students. As a result of Covid-19, a state of emergency was decreed, and classes in the public school system were interrupted, making it necessary to place around 40 million students without in-person classes. Objectives: To verify the main actions of the states and the Federal District concerning school meals during the pandemic and whether they are aligned with Federal Law No. 13.987/2020. Methods: We carried a narrative literature review using the information on the main actions carried out by the states and the Federal District, from reports, official bulletins, Ministry of Education homepages, decrees, or state ordinances, between March and May 2020. Results and Discussion: The main actions that all 26 Brazilian states and the Federal District carried out during the suspension of classes were different: six Brazilian states opted for the direct transfer of income; nine distributed food kits, five of which included family farming items; and the Federal District carried out the two modalities mentioned above. It is noteworthy that such actions were focused on the beneficiary families of the Bolsa Família (Family Allowance) Program. Furthermore, in certain states, the purchase of at least 30% of family farming was not considered. Conclusion: Although all states and the Federal District have acted to preserve the right to school meals for students in the public school system, we observed that such actions were heterogeneous and not aligned with Federal Law No. 13.987/2020.

RESUMO

Resumen El propósito de este trabajo fue hacer la detección de probables casos de trastornos de la conducta alimentaria (TCA) en adolescentes, así como analizar su relación con los hábitos alimentarios (HA) dentro del contexto escolar. Participaron 3,144 alumnos/as (49.7% chicas y 50.3% chicos), con edades entre 13 y 17 años (M = 14.41, DE = 0.79). Fueron registradas distintas variables: sociodemográficas, índice de masa corporal (IMC) e ingesta alimentaria, además de aplicar el Cuestionario de Actitudes Alimentarias (EAT-40) y el Cuestionario de Imagen Corporal (BSQ). Se identificaron diferencias significativas en EAT-40 y BSQ, con una mayor proporción de chicas vs. chicos que superaron el punto de corte. Respecto al IMC, aunque la mayoría estaba en normopeso, el 17.6% tuvo infrapeso, 20.4% sobrepeso y 7.1% obesidad. El 5.6% de todos los participantes fueron identificados como probables casos de TCA, con una mayor proporción de mujeres (9.6%) que de hombres (1.8%). No hubo correlación con los HA, pero sí mayor proporción de chicas que consumían menos alimentos y bebidas durante el desayuno y el recreo. Un dato alarmante es que 5.6% de las chicas y 2.5% de los chicos no consumían nada durante toda la mañana escolar.

Abstract A study of detection of probable cases of eating disorders (ED) in teenagers, studying their possible relationship with their dietary habits (DH) in the school context has been carried out. The participants were 3,144 students (49.7 % girls and 50.3 % boys) aged between 13 and 17 years old (M = 14.41, SD = 0.79). Different variables were recorded: sociodemographic, body mass index (BMI) and dietary intake, in addition to applying the Eating Attitudes Questionnaire (EAT-40) and the Body Shape Questionnaire (BSQ). Significant differences were identified in EAT-40 and BSQ, with a greater proportion of girls vs. boys exceeding the cut-off point. Regarding the BMI, although most were in normal weight, the 17.6% were underweight, 20.4% overweight and 7.1% obese. Based on all the data, 5.6% of all participants were identified as probable cases of ED, with a higher proportion of women (9.6%) that men (1.8%). There was no correlation with DH, but there were a higher proportion of girls who consumed less food and beverages during breakfast and recess. An alarming fact is that 5.6% of girls and 2.5% of boys did not consume anything during the whole school time.

RESUMO

Objetivo: Foram avaliadas as dificuldades no processo de compra /venda de produtos orgânicos da agricultura familiar para a alimentação escolar em 21 municípios do Sul do Brasil e identificadas as ações para superá-las. Métodos: Estudo quali-quantitativo realizado mediante entrevistas semiestruturadas com 111 informantes-chave envolvidos na alimentação escolar. Os entrevistados foram arguidos sobre as dificuldades da compra / venda de alimentos orgânicos para a alimentação escolar e sobre as ações que estão sendo desenvolvidas e/ou em planejamento para superação dessas problemáticas. Realizou-se análise descritiva das perguntas fechadas com base na distribuição da frequência e análise de conteúdo com codificação e categorização das questões abertas. Resultados: A maioria dos municípios (n=19) não comprava alimentos orgânicos provenientes da agricultura familiar. A pouca disponibilidade de mercado fornecedor e a baixa produção de alimentos orgânicos foram as dificuldades mais relatadas. Em contrapartida, os custos elevados dos produtos e a ausência de interesse da gestão pública na aquisição de alimentos orgânicos foram dificuldades pouco citadas. Os entrevistados apontaram que a compra/venda poderia aumentar com o fortalecimento dos processos de certificação participativa e se os envolvidos tivessem maiores informações sobre os benefícios e riscos dos modelos produtivos. Conclusões: Evidenciaram-se o fortalecimento da assistência técnica e extensão rural, desenvolvimento das regulamentações e incentivos para a certificação orgânica, apoio e investimento para a certificação participativa e orientações técnicas são estratégias necessárias para o incentivo da produção e consumo de alimentos orgânicos na alimentação humana.

Objective: To evaluate the difficulties in the process of buying/selling organic products from family farming for school meals in 21 municipalities in southern Brazil and to take actions to overcome them. Methods: This is a qualitative and quantitative study through semi-structured interviews with 111 key informants involved in school meals. The interviewees were asked about the difficulties of buying/selling organic food for school meals and about the actions developed and/or in planning to overcome these problems. Descriptive analysis of closed questions was performed based on frequency distribution and content analysis with coding and categorization of open questions. Results: Most municipalities (n = 19) did not buy organic food from family farming. The limited availability of the supplier market and the low production of organic foods were the most reported difficulties. On the other hand, the high costs of the products and the lack of interest by the public management in the acquisition of organic foods were difficulties little mentioned. Respondents highlighted that buying/selling could increase with the strengthening of participatory certification processes and if those involved had more information about the benefits and risks of productive models. Conclusions: The strengthening of technical assistance and rural extension, development of regulations and incentives for organic certification, support and investment for participatory certification, and technical guidelines were necessary strategies to encourage the production and consumption of organic human food.

RESUMO

RESUMEN El objetivo fue evaluar y comparar la alimentación en escolares de la ciudad de Santa Fe, Argentina que asisten a dos escuelas primarias públicas, una con (ECC) y otra sin comedor escolar (ESC). Se realizó un estudio descriptivo transversal, en alumnos de 1° a 5° grado. Se realizaron dos recordatorios de 24 hs y un cuestionario de frecuencia de consumo. En ambas escuelas, los niños consumieron las porciones recomendadas solo para el grupo carnes y huevos. Para verduras, frutas y lácteos, el consumo fue inferior a las recomendaciones en los niños de ambas escuelas. La distribución calórica de hidratos de carbono, proteínas y lípidos totales fue acorde a las recomendaciones, con una ingesta de grasa saturada superior al límite máximo recomendado, en los niños de ECC y ESC. Fue notable la baja ingesta de fibra en todos los escolares. En los niños de ambas escuelas, la ingesta de hierro fue adecuada, mientras que la ingesta de calcio fue muy por debajo de las recomendaciones. Los niños de la ESC presentaron mayor consumo diario de bebidas azucaradas y de golosinas. En este estudio se observó que la alimentación de los niños fue similar en presencia o ausencia de comedor escolar.

ABSTRACT The objective of this study was to examine and compare food intake among children from two public schools, one with and one without a school dining room, in Santa Fe, Argentina. A cross-sectional descriptive study was conducted among 1st to 5th grade students. Two 24-hour food recalls and a food frequency questionnaire were administered. In both schools, children consumed the recommended portions of meat and eggs only. For vegetables, fruits and dairy products, consumption was lower than recommended amounts among children of both schools. The caloric distribution of carbohydrates, proteins and total lipids was in accordance with recommendations, with saturated fat intake above the maximum recommended limit. The low fiber intake in all school children was notable. In children from both schools, iron intake was adequate, while calcium intake was well below recommended levels. The children from a school without a dining room had greater daily consumption of sugary drinks and candies. In this study, it was observed that the feeding of children was similar in the presence or absence of a school cafeteria.

RESUMO

In Brazil, at least 30% of the total financial resources provided by the federal government for school feeding should be used to buy products from family farming. The present study examines the profile of the purchase of these products in municipalities of the state of Rio Grande do Sul (RS), south Brazil, in 2014. A cross-sectional descriptive study was carried out with information obtained through a questionnaire sent to the municipalities and filled by respondents. Of the 371 participating municipalities, 367 acquired products from family farming, and 86.8% of these municipalities achieved the minimum percentage required. Nutritionists and farmers were the main components involved in the articulation of this process. Difficulties faced by these individuals included the lack of organization of the producers, failure to meet the demand, and lack of interest. More than 80% of the municipalities bought food from the “Vegetables”, “Cereals, Breads, Pasta, and Tubers” and “Fruits” groups. Only 8% purchased products from socio-biodiversity. There was a great diversity of food purchased, most of which were in natura, despite the low acquisition of socio-biodiversity products. Results of this study indicated the concern and tendency of the Brazilian municipalities to support the local economy with incentives to consumption and production of regional foods.(AU)

RESUMO

OBJECTIVE: To analyze the contribution of school meals to healthy food consumption among public school students in Brazil. METHODS: The data from the National Adolescent School-Based Health Survey (PeNSE), containing 86,660 ninth-grade students, were used. The students were asked about their consumption of school meals and of food in general over the preceeding seven days and on the day before the interview. A multinomial regression was performed to assess the relationship between the students' food consumption over the previous seven days and regular consumption of school meals (≥3 days/week), which were adjusted for sociodemographic factors. Poisson regression models were used for the relationship between food consumed on the day before the interview and regular consumption of school meals. RESULTS: Nearly one in five students (22.8%) stated that they consume school meals regularly. The adjusted analyses revealed that the consumption of school meals was associated positively with moderate (3-4 days/week) and regular (≥5 days/week) consumption of beans, raw or cooked vegetables, cooked vegetables, and fruits, and with moderate consumption of raw vegetables. In addition, school meal consumption was associated negatively with moderate or regular consumption of fried salty snacks and processed meat, and with regular consumption of packaged salty snacks, crackers, sweet biscuits, and sweets. Based on food consumption on the day preceding the interview, the consumption of school meals significantly affect the consumption of raw and cooked vegetables, and fruits. CONCLUSION: School meal consumption affects positively the consumption of healthy foods among students.

RESUMO

OBJECTIVE: To evaluate breakfast location and children's food choices. METHODS: Cross-sectional analysis of 1,371 fourth- through sixth-grade students in 2013. Foods and beverages in 17 categories characterized breakfast choices: (1) ≥ 1 fruits or vegetables, (2) ≥ 1 foods high in saturated fats and added sugars (SFAS), and (3) meeting School Breakfast Program (SBP) requirements. RESULTS: Among breakfast eaters (n = 1,133; 82.6%), 46.0% ate at home, 13.1% ate at school, 41.0% ate at multiple locations; and 21.8% ate at a corner store. Those eating at school were more likely to consume ≥1 fruit or vegetable (odds ratio [OR] = 1.90; 95% confidence interval [CI], 1.26-2.87), less likely to eat ≥1 SFAS food (OR = 0.46; 95% CI, 0.22-0.94), and more likely to meet SBP requirements (OR = 2.47; 95% CI, 1.42-4.29). Those eating at corner stores (n = 247) were more likely to consume high-SFAS foods (63.9% vs 9.2%; P < .001). CONCLUSIONS AND IMPLICATIONS: Eating school breakfast increased the odds of consuming fruit, choosing lower SFAS, and meeting nutritional requirements of the SBP relative to other locations.
