Sedentary behavior is associated with the mental health of university students during the Covid-19 pandemic, and not practicing physical activity accentuates its adverse effects: cross-sectional study.

BACKGROUND: Movement behaviours, such as sedentary behavior (SB) and physical inactivity, have become a public health issue due to their implications for physical and mental health. The literature indicates that the university environment influences the movement behaviors of university students, and the strategies adopted during the pandemic may have favored a decrease in the practice of physical activity and an increase in the time dedicated to SB in this population. We aimed to evaluate the association of SB and moderate to vigorous leisure-time physical activity (MVPA) with presence of symptoms of mental disorders during the COVID-19 pandemic. METHODS: This is a multicenter survey conducted with undergraduate students from eight Brazilian universities between October 2021 and February 2022 using an online questionnaire. The outcome variable was symptoms of anxiety and depression, assessed by the Depression, Anxiety, and Stress Scale-21. SB was assessed by total sitting time, being that individuals with ≥ 9 h/day were classified with high SB. The practice of MVPA was evaluated based on weekly frequency, duration, and type of exercise. Subsequently, the ratio between the time spent in MVPA (minutes/day) and the time spent in SB (hours/day) was calculated, being considered as cutoff point was the practice of 2.5 min of MVPA for each sedentary hour. To assess the association between the outcome and explanatory variables, multivariable logistic regression was performed. RESULTS: A total of 8,650 students participated in the study, with an average age of 23.9 years (SD: ± 6.34). In the multivariate analysis, the odds of anxiety symptoms [OR: 1.37 (95% CI: 1.24-1.50)] and depression [OR: 1.61 (95% CI: 1.47-1.77)] were higher in individuals with ≥ 9 h of SB per day. In the analysis of the relationship between MVPA and SB, not engaging in 2.5 min of MVPA per hour of SB increases the odds of anxiety symptoms [OR: 1.44 (95% CI: 1.31-1.58)] and depression [OR: 1.74 (95% CI: 1.59-1.92)]. CONCLUSION: The results suggest that SB is a risk factor associated with symptoms of anxiety and depression and that not engaging in MVPA exacerbates the negative effects of SB.

Effects of the Rango Cards game intervention on food consumption, nutritional knowledge and self-efficacy in the adoption of healthy eating practices of high school students: a cluster randomised controlled trial.

OBJECTIVE: The study aimed to assess the impact of a game-based nutritional intervention on food consumption, nutritional knowledge and self-efficacy in the adoption of healthy eating practices. DESIGN: This cluster randomised controlled trial included both male and female high school students from private schools in the Federal District, Brazil. Four schools were randomly selected for each group. Investigated variables were age, sex, monthly family income, maternal education level, dietary perceptions and practices, nutritional knowledge and self-efficacy in the adoption of healthy eating practices. SETTING: Intervention group participants were instructed to play Rango Cards, a digital game developed for the study, on their own, for a period of 7-17 d, while the control group was not provided with any game or material during the study. PARTICIPANTS: The study included 319 adolescents (mean age = 15·8 (sd 0·7) years). RESULTS: Significant reductions were observed in the intervention group compared with the control group for the following variables: habit of eating while watching TV or studying and having meals at fast food restaurants. The intervention group showed increased knowledge of the effects of fruit and vegetable consumption as well as improved self-efficacy in the adoption of healthy eating practices such as reducing Na intake and preparing healthy meals. CONCLUSIONS: The design of Rango Cards is potentially capable of effecting positive changes. Therefore, the digital game promotes autonomy and self-care among adolescents with regard to healthy eating.

Rango Cards, a digital game designed to promote a healthy diet: a randomized study protocol.

BACKGROUND: Several food and nutrition education actions have been described in the literature, with emphasis on the recommended use of innovative methods when addressing a young audience. Digital games are an attractive, dynamic, and motivating resource for teaching and learning practices, and adolescents form the group that readily accepts and adopts new technologies. Adapting dietary and nutritional guidelines to change dietary behavior is a challenge, and game-based learning has several benefits that can be used in this sense. Thus, this study aims to outline a nutritional intervention for school-aged adolescents from the Federal District, Brazil, whose object is a digital card game aimed at promoting healthy dietary practices. METHODS: In this randomized study with intervention and control groups, we propose a nutritional intervention for adolescents studying in Federal District private schools. The intervention group will be introduced to Rango Cards, a digital game specifically developed for this study. The purpose of the game is to present the concept of an adequate and healthy diet using simple information in a playful context. This game features cards for foods/meals, characters, and healthy habits. The players' choices may lead them to winning or losing. Theme selection and phase order were designed to provide a learning experience. The control group will not receive any material during the study. Both groups will complete questionnaires before and after the intervention. The game is expected to improve food knowledge and self-efficacy in the adoption of healthy practices, thus contributing to appropriate dietary consumption. DISCUSSION: The game was designed as a food and nutrition education tool based on Brazilian dietary guidelines. We believe that Rango Cards will provide a comprehensive experience on the topic, improving the students' autonomy, motivation, and pleasure of learning.

Healthy eating through the eyes of adolescents: A qualitative analysis of messages from the Dietary Guidelines for the Brazilian Population / Alimentação saudável na ótica de adolescentes: uma análise qualitativa das mensagens do Guia Alimentar para a População Brasileira

ABSTRACT Objective To evaluate the interpretation by adolescents of messages contained in the Dietary Guidelines for the Brazilian Population. Methods Qualitative study of adolescents distributed across "conversation circles". Each group received messages about healthy eating from the Dietary Guidelines and was instructed to develop materials containing their own interpretation thereof, using appealing wording and format. Content analysis was then used to evaluate these materials. Results Presentation of the produced materials revealed a focus on placing the participants at the center of the process and highlighting the dynamic and innovative nature of each strategy. Corpus analysis identified three clusters of meaning: (I) Food classification and selection model: The participants showed comprehension of the different formulations of foods and their impacts on health, but using other terms. A reductionist understanding of the composition of a healthy diet was observed; (II) Environment and eating practices: the environment was characterized as conducive or not to healthy eating, and open-air markets were recognized as spaces for healthy choices. Creating recipes was judged a wise choice to be shared; and (III) Diet-related individual and collective wellness: consequences of unhealthy food intake were linked to physical and emotional well-being. Concerns were raised about the use of natural resources and the impact of pesticides on individuals and the environment. Conclusion To facilitate understanding of the Dietary Guidelines, the wording of its messages must be adapted, and the discussion about healthy eating and proper diet must be broadened to ascribe greater value to the act of cooking in this population.

RESUMO Objetivo Avaliar a interpretação sobre as mensagens do Guia Alimentar para a População Brasileira na ótica de adolescentes. Métodos Estudo qualitativo com adolescentes distribuídos em rodas de conversa. Cada grupo trabalhou com mensagens sobre alimentação saudável do Guia Alimentar e foram orientados a elaborar materiais contendo a interpretação dos adolescentes, com linguagem e formato atrativos. Realizou-se análise de conteúdo do material. Resultados A apresentação do material enfatizou a necessidade de mostrar o protagonismo dos participantes, a dinamicidade e a inovação criada em cada estratégia. Do corpus, emergiram três núcleos de sentido: (I) Modelo de classificação e escolha dos alimentos: verificou-se compreensão das diferentes formulações dos alimentos e seus impactos na saúde, mas com adoção de outras terminologias. Observou-se entendimento reducionista sobre a composição de uma alimentação saudável; (II) Ambiente e práticas alimentares: o ambiente foi caracterizado como favorável ou não a uma alimentação saudável e feiras livres foram reconhecidas como espaços para escolhas saudáveis. Criar preparações culinárias foi avaliado como uma opção acertada a ser compartilhada; (III) Bem-estar individual e coletivo relacionados à alimentação: consequências do consumo de alimentos não saudáveis foram vinculadas ao bem-estar físico e emocional. Destacaram-se preocupações sobre a utilização dos recursos naturais e agrotóxicos para indivíduos e ambiente. Conclusão Para facilitar o entendimento do Guia Alimentar é necessário adaptar a linguagem das mensagens e ampliar a discussão sobre alimentação saudável e adequada, valorizando o ato de cozinhar nesse grupo.

[Panorama of purchasing food products from family farmers for the Brazilian School Nutrition Program]. / Panorama da compra de alimentos da agricultura familiar para o Programa Nacional de Alimentação Escolar.

This article seeks to describe the viewpoint of purchasing food products from family farmers, analyzing their performance within the new guidelines of the Brazilian School Nutrition Program (PNAE). It is a critical assessment based on a review of the literature and the official data provided by the National Fund for the Development of Education/Ministry of Education relating to 2010. The program budget in 2010 was approximately R$2.5 billion and attended 45.6 million children, adolescents and adults. From the total amount, R$150,397,052.68 was allocated for the purchase of agricultural products from family farmers. In Brazil, 47.4% of the local councils acquired food products from family farmers for the Brazilian School Nutrition Program and the purchase percentage was, on average, 22.7%. Given the nature of recent legislation, other aspects should be explored in order to strengthen the compliance with the regulations in different Brazilian contexts and thus contribute both to local economic development and the provision of school meals which fulfill the principles of a healthy and adequate diet.

Análise dos pareceres conclusivos dos Conselhos de Alimentação Escolar sobre a execução do Programa Nacional de Alimentação Escolar / Analysis of the School Food Council conclusive reports on the implementation of the National School Food Program

OB JETIVO: Analisar as informações contidas nos pareceres dos Conselhos de Alimentação Escolar de todo o Brasil sobre a execução do Programa Nacional de Alimentação Escolar. MÉTODOS: Estudo quantiqualitativo que analisa 4.256 pareceres na fase quantitativa e 2.299 na qualitativa, referentes ao ano de 2009. Também foram analisados 4.135 Demonstrativos Sintéticos Anuais, que tratam da execução físico-financeira do Programa. Na fase qualitativa, investigou-se o conteúdo dos pareceres por meio da técnica de análise de conteúdo. RESULTADOS: A análise quantitativa mostrou que, em 24,4% (n=1.009) das localidades, não houve contrapartida da entidade executora na compra de gêneros alimentícios, e a maioria dos pareceres (78,7%, n=3.348) apresentou assinatura de apenas um conselheiro. A análise qualitativa dos pareceres apontou que 64,5% (n=1.483) das localidades brasileiras adotavam a gestão centralizada e que 23,9% (n=549) das entidades executoras investiam recursos próprios na compra de gêneros alimentícios. A modalidade de licitação mais frequente foi o pregão (32,7%, n=751), e apenas 4,9% (n=112) dos pareceres afirmaram realizar a compra de alimentos oriundos da agricultura familiar. Entre as atribuições dos conselhos, ressaltaram-se a análise da prestação de contas (59,1%, n=1.359) e o acompanhamento da elaboração dos cardápios (36,5%, n=838) como sendo as mais frequentes. CONCLUSÃO: A execução do Programa Nacional de Alimentação Escolar em suas diferentes vertentes foi evidenciada pela análise dos pareceres dos Conselhos de Alimentação Escolar e dos Demonstrativos Sintéticos Anuais, caracterizando-os como instrumentos de monitoramento do Programa. Os achados servem de subsídio para estratégias de melhoria da qualidade da alimentação escolar e fortalecimento do Conselho de Alimentação Escolar.

OBJECTIVE: This study analyzed the conclusive reports of the Brazilian School Food Council on the implementation of the National School Food Program. METHODS: This quantitative and qualitative study analyzed 4,256 reports in the quantitative phase and 2,299 reports in the qualitative phase. The reports were issued in 2009. A total of 4,135 annual synthetic statements on physical and financial implementation of the Program were also analyzed. The reports were analyzed in the qualitative phase by content analysis. RESULTS: Quantitative analysis showed that the implementing party provided no consideration for food purchase in 24.4% (n=1,009) of the locations, and 78.7% (n=3,348) of the reports were signed by a single council member. Qualitative analysis of the reports showed that 64.5% (n=1,483) of the locations were under a central management and that 23.9% (n=549) of the implementing parties purchased food with their own funds. Most auctions were open ascending price auctions (32.7%, n=751) and only 4.9% (n=112) of the reports disclosed buying foods from family farms. The main council responsibilities are analyzing the expense reports (59.1%, n=1,359) and following menu development (36.5%, n=838). CONCLUSION: Execution of the different parts of the National School Food Program was evidenced by analyzing the School Food Council reports and annual synthetic statements, which characterized them as program-monitoring tools. The findings may help to support the strategies used for improving the quality of school food and strengthening the School Food Council.

Panorama da compra de alimentos da agricultura familiar para o Programa Nacional de Alimentação Escolar / Panorama of purchasing food products from family farmers for the Brazilian School Nutrition Program

O artigo tem por objetivo apresentar um panorama da compra de alimentos provenientes da agricultura familiar, analisando o seu cumprimento frente às novas diretrizes de execução do Programa Nacional de Alimentação Escolar (PNAE). Trata-se de ensaio crítico realizado com base em revisão da literatura e em dados oficiais fornecidos pelo Fundo Nacional de Desenvolvimento da Educação/Ministério da Educação/PNAE, referentes às prestações de contas dos órgãos gestores municipais relativas ao exercício 2010. O orçamento do PNAE em 2010 foi de aproximadamente R$ 2,5 bilhões e beneficiou 45,6 milhões de estudantes da educação básica e de jovens e adultos. Deste montante, R$ 150.397.052,68 foram destinados para a compra da agricultura familiar. No Brasil, 47,4% dos municípios adquiriram alimentos da agricultura familiar para o PNAE e o percentual médio de compra nestes municípios foi de 22,7%. Em função do caráter recente da legislação, destaca-se a necessidade de organização de gestores e agricultores para a efetivação desta normativa nos diferentes contextos brasileiros e assim contribuir tanto para o desenvolvimento econômico local, como para o fornecimento de refeições aos escolares que atendam aos princípios de uma alimentação saudável e adequada.
