Artigo Dietary and nutritional profiles among Brazilian adolescents(Nutrients, 2022-10) Lyra, Clelia de Oliveira; Vale, Diôgo; Dantas, Natalie Marinho; Andrade, Maria Eduarda da Costa; Oliveira, Angelo Giuseppe Roncalli da CostaBackground: The present study analyzed the prevalence of dietary and nutritional profiles among Brazilian adolescents and their associations with social determinants of health. Methods: A population-based survey was administered to 16,409 adolescents assessed by the 2015 National School Health Survey. A multivariate model of dietary and nutritional profiles was estimated from correspondence analysis. Results: The dietary and nutritional profiles more prevalent among Brazilian adolescents were “lower nutritional risk dietary pattern and eutrophic” (42.6%), “lower nutritional risk dietary pattern and overweight” (6.8%), and “higher nutritional risk dietary pattern and overweight” (6.0%). Healthier profiles were associated with less urbanized territories, healthpromoting behaviors, and families with worse material circumstances. The less healthy profiles were associated with more urbanized environments, health risk behaviors, and families with better material circumstances. Brazilian adolescents have different dietary and nutritional profiles that are characterized by sociopolitical and economic contexts, family material and school circumstances, and the behavioral and psychosocial health factors of the individuals. All of this points to the social determination of these health problems among adolescents in BrazilArtigo Dietary environmental footprints and their association with socioeconomic factors and food purchase practices: brazuca natal study(Foods, 2022-11) Lyra, Clélia de Oliveira; Hatjiathanassiadou, Maria; Souza, Camila Valdejane Silva de; Vale, Diôgo; Dantas, Natalie Marinho; Batista, Yasmim Bezerra; Marchioni, Dirce Maria Lobo; Lima, Severina Carla Vieira Cunha; Rolim, Priscilla Moura; Seabra, Larissa Mont’alverne JucáThe analysis of dietary environmental impacts has proven to be an important tool for guiding the adoption of healthier and more sustainable diets. This study aimed to estimate the dietary carbon (CF), water (WF), and ecological (EF) footprints of residents in the city of Natal, Brazil; the study also aimed to verify their association with socioeconomic factors and food purchase practices. This is a cross-sectional study that used dietary data from 411 adults and elderlies, which was collected via a questionnaire that applied to the respondents. The results showed that the dietary CF was 1901.88 g CO2 eq/day/1000 kcal, the WF was 1834.03 L/day/1000 kcal, and the EF was 14.29 m2/day/1000 kcal. The highest environmental footprint values showed an association (p ≤ 0.05) with the factors of male sex, white ethnicity, and higher income and schooling, whereas the lowest environmental footprint values were associated with social vulnerability variables such as female sex, non-white ethnicity, and lower income and schooling (p ≤ 0.05). Moreover, people with lower environmental footprints consumed less fast food, had fewer meals at snack bars, and used food delivery services less often than those with higher footprints. The foods that most contributed to the CFs and WFs were beef and chicken, while fish and beef contribute the most to the EFs. The data in the present study show that a diet with a lower environmental impact is not always equal to a sustainable diet. This relationship is paradoxical and relates to food justice, as people with lower environmental footprint values are the same ones with worse socioeconomic conditions. In this sense, is it essential to consider the influence of the social context when assessing dietary environmental impacts and when assessing actions that promote healthier and more sustainable dietsArtigo Dietary environmental footprints and their association with socioeconomic factors and food purchase practices: BRAZUCA Natal study(Foods, 2022) Lima, Severina Carla Vieira Cunha; Hatjiathanassiadou, Maria; Souza, Camila Valdejane Silva de; Vale, Diôgo; Dantas, Natalie Marinho; Batista, Yasmim Bezerra; Marchion, Dirce Maria Lobo; Lyra, Clélia de Oliveira; Rolim, Priscilla Moura; Seabra, Larissa Mont’Alverne Jucá; https://orcid.org/0000-0001-8268-1986The analysis of dietary environmental impacts has proven to be an important tool for guiding the adoption of healthier and more sustainable diets.

A checklist was applied and coliform analysis at 45 °C. Aerobic mesophilic bacteria on surface boards used in food handling were also counted. It was observed that most of the canteens were considered unsatisfactory in terms of compliance with good handling practices. Presence of coliforms at 45 °C was noted in 72% of the food handling surface boards. With respect to mesophilic bacteria, 81% of the boards presented values above the recommended. According to the results, it is possible to say that based on hygienic-sanitary guidelines, the canteens were not in accordance with Brazilian law that regulates good manufacture practices of the food service industry and recommends that facilities, equipment and utensils used in food handling are in proper hygienic-sanitary conditions. The food production process for the university population was not properly carried out due to non-compliance with good handling practices. Thus, the health of thousands of students and staff who have their meals daily at the university canteens may be at risk.Artigo Pegada hídrica da alimentação de adolescentes do Brasil: relações com o consumo de fast food e o local de moradia(Research, Society and Development, 2021) Seabra, Larissa Mont’Alverne Jucá; Vale, Diôgo; Dantas, Natalie Marinho; Souza, Camila Vald ejane Silva de; Hatjiathanassiadou, Maria; https://orcid.org/0000-0002-1878-4283O objetivo deste estudo foi estimar as pegadas hídricas da alimentação de adolescentes escolares do Brasil e as associações com contexto territorial e de rotina alimentar. Trata-se de um estudo ecológico a partir dos microdados da amostra 1 da Pesquisa Nacional de Saúde do Escolar 2015, com as quais foram estimadas as médias das pegadas hídricas medias (PH) da alimentação dos adolescentes por categoria de análise: unidade da federação brasileira, macrorregião geográfica e por número de dias na semana frequentado restaurantes fast food. Estatísticas descritivas e espaciais foram empregadas para compreensão da distribuição dessas médias nas unidades de análise territoriais e na frequência em fast food. No Brasil, a PH média da alimentação dos adolescentes foi 2925,9 litros/kg. A distribuição das PH apresentou forte correlação espacial (Índice de Moran Local=0,773), com destaque para formação do cluster do tipo alto-alto (Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Rio de Janeiro, Espírito Santo, Minas Gerais e Mato Grosso do Sul). Além disso, as PH médias da alimentação desse grupo aumentaram proporcionalmente ao aumento do número de dias que o adolescente costumava comer em fast food. Percebe-se uma relação direta entre o maior impacto ambiental da alimentação de adolescentes, territórios de moradia mais urbanizados e a maior frequência em restaurantes fast food. Avaliar essas associações é importante para compressão das questões de saúde pública e nutrição na perspectiva da sustentabilidade. Assim, podem ser desenvolvidas estratégias para redução do impacto ambiental e melhoria da alimentação desse grupo etárioArtigo Portuguese typical starter soups: does salt reduction affect perception and sensory quality at a university canteen?(Journal of Culinary Science & Technology, 2021-03) Damasceno, Karla Suzanne Florentino da Silva Chaves; Dantas, Natalie Marinho; Silva, Maria Elisabeth Machado Pinto e; Martins, Zita Emanuela; Dutra, Rafaela Rodrigues; Pinho, OlíviaControlling individuals’ salt intakes from discretionary sources is one of Portugal’s public health priority, to reduce factors risks for cardiometabolic diseases. Starter soups, turnip green (TG), Carrot (C) and Carrot with cabbage (CC), from a Portuguese university canteen, were evaluated by sodium content varying in salt addition, the usual amount of salt (R0); with 25% (R25), and 35% (R35) of salt reduction, respectively. One hundred and seven students participated in the research during lunchtime. Check-all-that-apply (CATA) was applied, as well as the acceptability and saltiness perception. There were no differences (p > 0.05) for acceptability and saltiness perception of TG and CC soups with different amounts of salt, but reduced salt samples of carrot soup were perceived to be saltier and overall more liked compared to its usual recipe. This data suggests that 35% of salt reduction is possible in complex matrices as Portuguese starter soups without a loss of acceptance by consumersArtigo Social determinants of obesity and stunting among Brazilian adolescents: a multilevel analysis(Nutrients, 2022-06) Lyra, Clelia de Oliveira; Vale, Diôgo; Andrade, Maria Eduarda da Costa; Dantas, Natalie Marinho; Bezerra, Ricardo Andrade; Oliveira, Angelo Giuseppe Roncalli da CostaBackground: The purpose of this study was to identify the prevalence of obesity and stunting among Brazilian adolescents and its associations with social determinants of health (individual, family, and school), grounded on the necessity of investigating the determinants of nutritional problems within this population. (2) Methods: A population-based survey was administered to 16,556 adolescents assessed by the 2015 National School Health Survey. Multivariate models of obesity and stunting were estimated from Multilevel Poisson Regressions. (3) Results: The prevalence of obesity among Brazilian adolescents (10.0%; 95% CI: 9.4–10.6) was associated directly with indifference or dissatisfaction with body image, with eating breakfast four or fewer days a week, living with up to four people in the household, studying in private schools, and being from the South region, and was inversely associated with being female, 15 years old or older, with having the highest nutritional risk eating pattern, dining at fast-food restaurants, and eating while watching television or studying. The prevalence of stunting (2.3%; 95% CI: 2.0–2.8) was directly associated with the age of 15 years or older, and inversely associated with the lower number of residents living in the household, maternal education—decreasing gradient from literate to college level education, studying in urban schools, and being from the South and Central-West regions. (4) Conclusions: Obesity in adolescence presented behavioral determinants. Stunting and obesity have structural social determinants related, respectively, to worse and better socioeconomic position among Brazilian adolescentsArtigo Vigilância alimentar e nutricional de adolescentes brasileiros: possibilidades com dados da PeNSE(Research, Society and Development, 2021-09) Lyra, Clélia de Oliveira; Vale, Diôgo; Andrade, Maria Eduarda da Costa; Dantas, Natalie Marinho; Seabra, Larissa Mont’alverne Jucá; Roncalli, Angelo GiuseppeA intensificação da Vigilância Alimentar e Nutricional (VAN) dos adolescentes é fundamental ao aprimoramento da gestão e produção do cuidado desse grupo etário no Brasil. Com isso, o objetivo deste trabalho foi descrever processos de tratamento de variáveis do banco de microdados da Pesquisa Nacional de Saúde do Escolar (PeNSE) e apresentar métodos multivariados que podem ser empregados na produção de informações para VAN de adolescentes do Brasil a partir desse inquérito populacional. Trata-se de um estudo metodológico com base na amostra 2 da PeNSE 2015. As principais contribuições são a descrição de aspectos das PeNSE; considerações sobre a ética da pesquisa com dados secundários; orientações sobre os bancos de microdados e a preparação para análise; o tratamento de variáveis de interesse para VAN - estado nutricional, consumo alimentar (estimativa de padrões e indicadores de sustentabilidade); variáveis compostas relacionadas ao comportamento alimentar de adolescentes; e as técnicas de análises múltiplas com dados categóricos que podem ser empregadas em estudos de associação. Ressalta-se que as ações de vigilância alimentar e nutricional de adolescentes no Brasil podem ser qualificadas a partir da intensificação de adequados estudos epidemiológicos com dados das PeNSE
