RESUMO

This study aimed to identify dietary patterns and to evaluate the association between body image perception and these patterns among schoolchildren. A cross-sectional study was conducted on 385 schoolchildren (both sexes, 10-17 years old) from four public schools in Salvador, Brazil. Two non-consecutive 24-hour dietary recalls were applied, and the dietary pattern was determined by Exploratory Factor Analysis after adjustment of dietary data using the Multiple Source Method. To evaluate body image perception, the Brazilian body shape silhouette was used. The associations between body image perception and dietary patterns using the polytomous logistic regression model adjusted for covariables was assessed. Three dietary patterns were obtained: "Western standard," unhealthy, "healthy pattern" and "typical dishes/ junk food." After adjustment, adolescents who wished for a slimmer silhouette (2.48 [95%CI: 1.04-6.11], 3.49 [95%CI: 1.35-9.05] and 2.87 [95%CI: 1.13-7.26]) were more likely to adhere to the quintiles with the lowest consumption of the Western standard, compared to those satisfied with their body image. No associations were identified in the other two dietary patterns. Adolescents dissatisfied with their bodies tend to adhere less to unhealthy dietary patterns.

Um estudo transversal foi conduzido em 385 escolares (ambos os sexos, 10-17 anos de idade) de 4 escolas públicas de Salvador, Brasil. Dois recordatórios alimentares de 24h não consecutivos foram aplicados e o padrão alimentar foi determinado por Análise Fatorial Exploratória, após ajuste dos dados dietéticos pelo Multiple Source Method. Para avaliar percepção da imagem corporal, nós usamos uma escala brasileira de silhuetas. Avaliamos as associações entre percepção da imagem corporal e padrões alimentares usando o modelo de regressão logística politômica ajustado para covariáveis. Três padrões alimentares foram obtidos: "padrão ocidental", "padrão saudável" e "comidas típicas/junk food". Após ajuste, adolescentes que desejavam uma silhueta menor (2,48 [IC95%: 1,04-6,11], 3,49 [IC95%: 1,35-9,05] e 2,87 [IC95%: 1,13-7,26]) tinham mais chances de aderir aos quintis de menor consumo do padrão ocidental, comparados àqueles satisfeitos com sua imagem corporal. Nenhuma associação foi identificada nos outros dois padrões alimentares. Adolescentes insatisfeitos com seus corpos tendem a aderir menos a padrões alimentares não saudáveis.

RESUMO

Introduction: The monitoring of nutrition and health claims on food and beverage labels has been proposed by international and national organizations because it can collaborate with the development of public policies to regulate food labeling and marketing strategies. One way of carrying out this monitoring is by using data collected by private companies. Objective: To compare information on nutrition and health claims available in a commercial database of a private company that monitors the launch of new foods and beverages in Brazilian food retailers with information on those same claims manually coded by trained research assistants. Methods: This is a cross-sectional observational study using a data sample of newly launched food and beverages available at a commercial database from 2018 to 2021. We compared the information on health and nutrition claims available on the commercial dataset with reliable information on the same nutrition and health claims manually coded by trained research assistants using a tested taxonomy to classify such claims. We used Gwet's Kappa AC1 with 95% CI and percentage agreement to compare both data sources and calculated sensitivity and specificity of the compared data. Results: A total of 6,722 foods and beverages were analyzed. Mintel-GNPD presented 36.28% (n = 2,439) of nutrition claims, while in the trained researchers' coding, it was 33.73% (n = 2,267). We found a prevalence of 5.4% (n = 362) for health claims in Mintel-GNPD and 10.8% (n = 723) in the researchers' coding. All subcategories of nutrition and health claims showed high agreement (Kappa >0.81). Health claims presented kappa = 0.89 with 33.7% sensitivity and 98.0% specificity while nutrition claims showed kappa = 0.86 with 92.9% sensitivity and 92.5% specificity. Conclusion: Nutrition and health claims showed high agreement, with great results in nutrition claims, indicating that Mintel-GPND is suitable for monitoring such claims on food and beverage packaging in Brazil. Additionally, our findings show a high prevalence of nutrition and health claims on food packages launched in the Brazilian food retail, highlighting the need to monitor these to develop public policies to regulate food marketing on packaging in Brazil.

RESUMO

Mechanisms of cell reprogramming by pluripotency-related transcription factors or nuclear transfer seem to be mediated by similar pathways, and the study of the contribution of OCT4 and SOX2 in both processes may help elucidate the mechanisms responsible for pluripotency. Bovine fibroblasts expressing exogenous OCT4 or SOX2, or both, were analyzed regarding the expression of pluripotency factors and imprinted genes H19 and IGF2R, and used for in vitro reprogramming. The expression of the H19 gene was increased in the control sorted group, and putative iPSC-like cells were obtained when cells were not submitted to cell sorting. When sorted cells expressing OCT4, SOX2, or none (control) were used as donor cells for somatic cell nuclear transfer, fusion rates were 60.0% vs. 64.95% and 70.53% vs. 67.24% for SOX2 vs. control and OCT4 vs. control groups, respectively; cleavage rates were 66.66% vs. 81.68% and 86.47% vs. 85.18%, respectively; blastocyst rates were 33.05% vs. 44.15% and 52.06% vs. 44.78%, respectively. These results show that the production of embryos by NT resulted in similar rates of in vitro developmental competence compared to control cells regardless of different profiles of pluripotency-related gene expression presented by donor cells; however, induced reprogramming was compromised after cell sorting.

RESUMO

Lianas (woody vines) are important components of tropical forests and are known to compete with host trees for resources, decrease tree growth and increase tree mortality. Given the observed increases in liana abundance in some forests and their impacts on forest function, an integrated understanding of carbon dynamics of lianas and liana-infested host trees is critical for improved prediction of tropical forest responses to climate change. Non-structural carbohydrates (NSC) are the main substrate for plant metabolism (e.g., growth, respiration), and have been implicated in enabling tree survival under environmental stress, but little is known of how they vary among life-forms or of how liana infestation impacts host tree NSC. We quantified stem total NSC (NSC) concentrations and its fractions (starch and soluble sugars) in trees without liana infestation, trees with more than 50% of the canopy covered by lianas, and the lianas infesting those trees. We hypothesized that i) liana infestation depletes NSC storage in host trees by reducing carbon assimilation due to competition for resources; ii) trees and lianas, which greatly differ in functional traits related to water transport and carbon uptake, would also have large differences in NSC storage, and that As water availability has a significant role in NSC dynamics of Amazonian tree species, we tested these hypotheses within a moist site in western Amazonia and a drier forest site in southern Amazonia. We did not find any difference in NSC, starch or soluble sugar concentrations between infested and non-infested trees, in either site. This result suggests that negative liana impact on trees may be mediated through mechanisms other than depletion of host tree NSC concentrations. We found lianas have higher stem NSC and starch than trees in both sites. The consistent differences in starch concentrations, a long term NSC reserve, between life forms across sites reflect differences in carbon gain and use of lianas and trees. Soluble sugar concentrations were higher in lianas than in trees in the moist site but indistinguishable between life forms in the dry site. The lack of difference in soluble sugars between trees and lianas in the dry site emphasize the importance of this NSC fraction for plant metabolism of plants occurring in water limited environments. Abstract in Portuguese and Spanish are available in the supplementary material.

RESUMO

BACKGROUND: Contextual factors are essential for understanding long-term adjustment to the COVID-19 pandemic. Therefore, the present study investigated changes in mental health outcomes and subjective pandemic-related experiences over time and across countries. The main objective was to explore how psychological responses vary in relation to individual and environmental factors. METHODS: The sample consisted of N = 1070 participants from the general population of Austria, Croatia, Georgia, Greece, and Portugal. We applied a longitudinal mixed-methods approach, with baseline assessment in summer and autumn 2020 (T1) and follow-up assessment 12 months later (T2). Qualitative content analysis by Mayring was used to analyse open-ended questions about stressful events, positive and negative aspects of the pandemic, and recommendations on how to cope. Mental health outcomes were assessed with the Adjustment Disorder-New Module 8 (ADNM-8), the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5), the Patient Health Questionnaire-2 (PHQ-2), and the 5-item World Health Organization Well-Being Index (WHO-5). The analyses were performed with SPSS Statistics Version 26 and MAXQDA 2022. RESULTS: The mental health outcomes significantly differed over time and across countries, with e.g. Greek participants showing decrease in adjustment disorder symptoms (p = .007) between T1 and T2. Compared with other countries, we found better mental health outcomes in the Austrian and the Croatian sample at both timepoints (p < .05). Regarding qualitative data, some themes were equally represented at both timepoints (e.g. Restrictions and changes in daily life), while others were more prominent at T1 (e.g. Work and finances) or T2 (e.g. Vaccination issues). CONCLUSIONS: Our findings indicate that people's reactions to the pandemic are largely shaped by the shifting context of the pandemic, country-specific factors, and individual characteristics and circumstances. Resource-oriented interventions focusing on psychological flexibility might promote resilience and mental health amidst the COVID-19 pandemic and other global crises.

RESUMO

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.

RESUMO

This article aims to characterize the advertising appeals present in the food environment to market ultra-processed foods and to analyze the nutritional profile of these foods according to PAHO criteria and the presence of food additives. Cross-sectional study, with data audited in 20 small supermarkets in São Paulo. The INFORMAS protocol was used to classify the advertising messages. The foods were classified according to NOVA. The PAHO profile model was used to classify foods high in critical nutrients. Advertising patterns were identified by factor analysis. The association between patterns and food groups was investigated by linear regression. More than 95% of the ultraprocessed foods had at least 1 critical nutrient in excess. There was a positive association between the new brand, fun and advantageous pattern with snacks, ready-made products, dairy products and cookies; between the new brand and suggested use pattern with dairy products. The standardization of food advertising in small retail stores is associated with offering snacks, dairy products, ready-to-eat foods and cookies, products that exceed critical nutrients.


O objetivo deste artigo é caracterizar os apelos publicitários presentes no ambiente alimentar para comercializar alimentos ultraprocessados e analisar o perfil nutricional desses alimentos segundo critérios da OPAS e presença de aditivos alimentares. Estudo transversal, com dados auditados em 20 pequenos supermercados de São Paulo. O protocolo INFORMAS foi utilizado para classificar as mensagens publicitárias. Os alimentos foram classificados segundo a NOVA. O perfil nutricional da OPAS foi utilizado para classificar os alimentos elevados em nutrientes críticos. Os padrões de publicidade foram identificados por análise fatorial. A associação entre os padrões e os grupos de alimentos foi investigada por regressão linear. Mais de 95% dos alimentos ultraprocessados tinham pelo menos um nutriente crítico em excesso. Verificou-se associação positiva entre o padrão nova marca, divertido e vantajoso com salgadinhos, produtos pré-prontos, lácteos e biscoitos, e entre o padrão nova marca e uso sugerido com lácteos. A padronização da publicidade de alimentos nos pequenos comércios varejistas está associada à oferta de salgadinhos, produtos lácteos, alimentos pré-prontos e biscoitos, produtos que excedem em nutrientes críticos.

RESUMO

Background: The complex system of stressors related to the coronavirus disease 2019 (COVID-19) pandemic has affected the global population, provoking a broad range of psychological reactions. Although numerous studies have investigated the mental health impact of COVID-19, qualitative research and cross-country comparisons are still rare. Objective: This qualitative study aimed to explore self-perceived challenges and opportunities related to COVID-19 across six European countries. The overall objective was to provide a differentiated picture of individual subjective experiences in the early stages of the pandemic. Method: The present study included 7309 participants from Austria, Croatia, Georgia, Greece, Poland, and Portugal. We performed qualitative content analysis according to Mayring analyse open-ended questions regarding stressful events, positive and negative aspects of the pandemic, and recommendations to cope with the pandemic situation. MAXQDA software was used for data management and analysis. Results: Participants' accounts were moderately consistent across the countries. The most prominent themes regarding stressful and negative pandemic aspects included: Restrictions and changes in daily life, Emotional distress, and Work and finances. Answers about positive pandemic consequences were mainly centred around the themes Reflection and growth, Opportunity for meaningful/enjoyable activities, and Benefits on interpersonal level. Key themes identified from participants' recommendations to cope with the pandemic included Beneficial behavioural adjustment, Beneficial cognitive-emotional strategies, and Social support. Conclusions: Participants experienced various challenges, but also shared several positive pandemic consequences and recommendations to cope with the pandemic. These first-hand data could inform mental health practices to promote well-being during COVID-19 and similar global challenges in the participating countries and possibly beyond. HIGHLIGHTS: We examined COVID-19-related experiences in 7309 adults from six European countries.Besides challenges, participants identified many positive pandemic consequences.Participants' recommendations to cope with COVID-19 included behavioural and cognitive-emotional strategies.

To evaluate how scientific production in food and nutrition in Latin America has incorporated the NOVA classification. Materials and methods. The analysis of scientific production was carried out from annals at the Latin American Congress of Nutrition (SLAN) in 2012, 2015 and 2018. The terms used for the search were: NOVA, ultra-processed, processed, processing and food guide, in Portuguese, English and Spanish. After the search, the exclusion and inclusion criteria were applied and the selected abstracts were described according to previously defined analytical variables. Results. A total of 153 were analyzed, 24 of which were published in 2012, 20 in 2015 and 109 in 2018. Most studies were carried out in Brazil (56,2%), followed by Mexico (12,4%) and involved adolescents (28,8%), adults (21,6%) and food (19,6%) as subject or unit of analysis. Most of the works were classified in the area of Public Health Nutrition (88,9%), were observational (82,3%) and used a quantitative method (76,5%). The sale and/or consumption of food (46,4%) and the food environment (24,2%) were the most common objects of study. Conclusion. The scientific production that considers the NOVA classification in Latin America increased in 2018, with Brazil and Mexico leading the development of studies. Studies that explore the relationship of NOVA classification to food price, culinary skills and public policy analysis are research opportunities(AU)

RESUMO

The availability of ultra-processed foods in a municipality tends to be related to different types of food retailers and their location in the territory, besides social, economic, and demographic factors. The aim of this study was to evaluate the availability of ultra-processed foods according to different types of food retailers and sociodemographic factors. This is a cross-sectional observational study carried out with audit data from food retailers in the municipality of Jundiaí, SP. Using a validated instrument, data on the availability of 18 types of ultra-processed foods were used to create a score of ultra-processed foods, ranging from 0 to 100 points, and five subscores referring to the ultra-processed food subgroups. Descriptive statistics and means comparison tests were performed to verify differences in the ultra-processed food availability score, according to the food retail type, household income, number of household members, and percentage of people of the color population in the census tract in which food retailers were located. Geo-referenced maps were used to characterize the score of ultra-processed in the territory, according to sociodemographic variables. A total of 649 food retailers were analyzed, most of which were classified as neighborhood markets (25.4%). The supermarkets were the category with the highest ultra-processed food availability score. Among the subgroups of ultra-processed foods analyzed, candies, soft drinks, and snacks were available in 60% of the food retailers. Higher ultra-processed food availability score was observed in regions with lower income, higher percentage of people of color population, and higher number of members per household. The findings show that the greater availability of ultra-processed foods is related to supermarkets and markets and regions of greater social vulnerability, which can put this population at nutritional risk.

RESUMO

The color of plant leaves can be assessed qualitatively by color charts or after processing of digital images. This pilot study employed a novel pocket-sized sensor to obtain the color of plant leaves. In order to assess its performance, a color-dependent parameter (SPAD index) was used as the dependent variable, since there is a strong correlation between SPAD index and greenness of plant leaves. A total of 1,872 fresh and intact leaves from 13 crops were analyzed using a SPAD-502 meter and scanned using the Nix™ Pro color sensor. The color was assessed via RGB and CIELab systems. The full dataset was divided into calibration (70% of data) and validation (30% of data). For each crop and color pattern, multiple linear regression (MLR) analysis and multivariate modeling [least absolute shrinkage and selection operator (LASSO), and elastic net (ENET) regression] were employed and compared. The obtained MLR equations and multivariate models were then tested using the validation dataset based on r, R2, root mean squared error (RMSE), and mean absolute error (MAE). In both RGB and CIELab color systems, the Nix™ Pro color sensor was able to differentiate crops, and the SPAD indices were successfully predicted, mainly for mango, quinoa, peach, pear, and rice crops. Validation results indicated that ENET performed best in most crops (e.g., coffee, corn, mango, pear, rice, and soy) and very close to MLR in bean, grape, peach, and quinoa. The correlation between SPAD and greenness is crop-dependent. Overall, the Nix™ Pro color sensor was a fast, sensible and an easy way to obtain leaf color directly in the field, constituting a reliable alternative to digital camera imagery and associated image processing.

RESUMO

This study aims to explore potential barriers and facilitators for healthy eating in the consumer food environment, and to analyze the association with different types of food retailers, having as theoretical reference the Dietary Guidelines for the Brazilian Population. This is a cross-sectional study carried out in the municipality of Jundiaí, São Paulo State, Brazil, with audits of the consumer food environment carried out in 650 retail stores. We identified barriers and facilitators of healthy food choices in the internal environment of the retail. Factor analysis estimated factors that characterized the environment according to barriers and facilitators. Linear regression evaluated the association between the factors and the different categories of establishments. Most establishments had priority sales of ultra-processed products. Out of the total food retailers studied, 75.9% offered sugary drinks; 37% rice, beans and 30% fruits and vegetables. We characterized the first factor by the presence of both barriers and facilitators (mixed factor), the second factor by more facilitators and the third by greater presence of barriers in the consumer environment. Supermarkets were positively associated with the three factors (p-value < 0.001). The fruit and vegetable stores and the neighborhood markets had a positive association with the most facilitating factor (p-value < 0.001). Markets and bakeries were positively associated with the more barriers factor (p-value < 0.001). The patterns that characterize barriers and facilitators for healthy eating differ significantly according to types of food retailers.


O objetivo deste trabalho é explorar potenciais barreiras e facilitadores para alimentação saudável no ambiente alimentar do consumidor e analisar a associação com diferentes tipos de estabelecimentos comerciais tendo como referencial teórico o Guia Alimentar para a População Brasileira. Estudo transversal realizado no Município de Jundiaí, São Paulo, Brasil, com auditoria do ambiente alimentar do consumidor realizada em 650 comércios varejistas. Foram identificados barreiras e facilitadores das escolhas alimentares saudáveis no ambiente interno dos comércios. Análise fatorial foi utilizada para estimar fatores que caracterizassem o ambiente segundo barreiras e facilitadores. Regressão linear foi utilizada para avaliar a associação entre os fatores e as diferentes categorias de estabelecimentos. A maioria dos estabelecimentos tinham venda prioritária de ultraprocessados. Do total de comércios estudados, 75,9% disponibilizavam bebidas açucaradas; 37% arroz, feijão e 30% frutas e hortaliças. O primeiro fator caracterizou-se pela presença tanto de barreiras quanto de facilitadores (fator misto), o segundo fator caracterizou-se por mais facilitadores e o terceiro por maior presença de barreiras no ambiente do consumidor. Supermercados foram associados positivamente com os três fatores (valor de p < 0,001). Os sacolões/hortifrutis públicos e privados, os mercados de bairro tiveram associação positiva com o fator mais facilitadores (valor de p < 0,001). Os mercados e padarias se associaram positivamente ao fator mais barreiras (valor de p < 0,001). Os padrões que caracterizam barreiras e facilitadores para alimentação saudável diferem de forma significativa segundo tipos de comércios.

El primer factor se caracterizó por la presencia tanto de barreras, como de facilitadores (factor mixto), el segundo se caracterizó por más facilitadores y el tercero por una mayor presencia de barreras en el ambiente del consumidor. Los supermercados fueron asociados positivamente con los tres factores (valor de p < 0,001). Las fruterías/verdulerías públicas y privadas, los mercados de barrio presentaron una asociación positiva con el factor más facilitadores (valor de p < 0,001). Los mercados y panaderías se asociaron positivamente con el factor más barreras (valor de p < 0,001). Los patrones que caracterizan barreras y facilitadores para la alimentación saludable difieren de forma significativa según los tipos de comercios.

RESUMO

A cirurgia de hérnia inguinal (HI) é um dos procedimentos mais comuns na prática do cirurgião geral. Estima-se que 20 milhões dessas operações sejam realizadas no mundo anualmente. Com o advento da técnica sem tensão e implante de tela sintética, as taxas de recidiva caíram expressivamente e a recidiva deixou de ser a principal complicação tardia após o reparo da hérnia inguinal. Hoje a principal complicação pós-operatória tardia da cirurgia de HI é a dor crônica inguinal pós-operatória (DCIP). A definição de DCIP é a dor pós-operatória da região inguinal após 3-6 meses da cirurgia. Relatamos o caso de um jovem paciente do sexo masculino que se apresentou com DCIP após ter sido previamente submetido a duas herniorrafias inguinais. Inicialmente apresentava dor inguinal a esquerda sem abaulamento evidente e na ocasião foi submetido a herniorrafia inguinal esquerda pela técnica de Lichtenstein. Não houve resolução da dor após a cirurgia. Após 1 ano foi novamente operado, dessa vez bilateralmente e infelizmente evoluiu com piora da dor apresentava dor predominantemente neuropática (em queimação e com irradiação para região testicular bilateralmente) e intensidade moderada (escala visual analógica 6), sem melhora com anti-inflamatórios não esteroidais ou analgésicos. Apresentava dor ao toque do anel inguinal externo bilateralmente, hiperestesia no teritório de nervos genito-femoral, ílio-hipogástrico e ílio-inguinal do lado esquerdo e hipoestesia no território dos três nervos do lado direito. Apresentou alívio temporário da dor após bloqueio anestésico inguinal bilateral. Paciente foi então submetido a triplo-neurectomia bilateral com remoção das telas de polipropileno. Em seguimento um ano após o tratamento cirúrgico, o paciente permanece sem dor inguinal. [au]


Inguinal hernia (IH) surgery is one of the most common procedures in the practice of the general surgeon. With adoption of tension-free technique and synthetic mesh implantation, recurrence rates decreased and recurrence is no longer the main late complication after IH repair. Currently, the main late postoperative complication of IH repair is chronic postoperative inguinal pain (CPIP). CPIP is defined as postoperative pain in the inguinal region persisting 3-6 months after surgery. We report the case of a young male patient who presented with CPIP after having undergone two inguinal hernia repairs. Initially, he had left inguinal pain without evident bulging and underwent left inguinal herniorrhaphy using the Lichtenstein technique. There was no relief of pain after surgery. After 1 year, he underwent surgery again, this time bilaterally and unfortunately the pain got worse. He had predominantly neuropathic pain (burning and irradiated to the testicular region bilaterally) and moderate intensity (visual analogue scale 6) refractory to medical management. He had hyperesthesia on the territory of the genitofemoral, iliohypogastric and ilioinguinal nerves on the left side and hypoesthesia in the territory of the three nerves on the right side. A local anesthetic inguinal block provided temporary relief. We performed a bilateral triple neurectomy with removal of the polypropylene mesh. Followed up one year after surgical treatment, the patient remains without inguinal pain. [au]

RESUMO

Resumo O objetivo deste artigo é caracterizar os apelos publicitários presentes no ambiente alimentar para comercializar alimentos ultraprocessados e analisar o perfil nutricional desses alimentos segundo critérios da OPAS e presença de aditivos alimentares. Estudo transversal, com dados auditados em 20 pequenos supermercados de São Paulo. O protocolo INFORMAS foi utilizado para classificar as mensagens publicitárias. Os alimentos foram classificados segundo a NOVA. O perfil nutricional da OPAS foi utilizado para classificar os alimentos elevados em nutrientes críticos. Os padrões de publicidade foram identificados por análise fatorial. A associação entre os padrões e os grupos de alimentos foi investigada por regressão linear. Mais de 95% dos alimentos ultraprocessados tinham pelo menos um nutriente crítico em excesso. Verificou-se associação positiva entre o padrão nova marca, divertido e vantajoso com salgadinhos, produtos pré-prontos, lácteos e biscoitos, e entre o padrão nova marca e uso sugerido com lácteos. A padronização da publicidade de alimentos nos pequenos comércios varejistas está associada à oferta de salgadinhos, produtos lácteos, alimentos pré-prontos e biscoitos, produtos que excedem em nutrientes críticos.


Abstract This article aims to characterize the advertising appeals present in the food environment to market ultra-processed foods and to analyze the nutritional profile of these foods according to PAHO criteria and the presence of food additives. Cross-sectional study, with data audited in 20 small supermarkets in São Paulo. The INFORMAS protocol was used to classify the advertising messages. The foods were classified according to NOVA. The PAHO profile model was used to classify foods high in critical nutrients. Advertising patterns were identified by factor analysis. The association between patterns and food groups was investigated by linear regression. More than 95% of the ultraprocessed foods had at least 1 critical nutrient in excess. There was a positive association between the new brand, fun and advantageous pattern with snacks, ready-made products, dairy products and cookies; between the new brand and suggested use pattern with dairy products. The standardization of food advertising in small retail stores is associated with offering snacks, dairy products, ready-to-eat foods and cookies, products that exceed critical nutrients.

RESUMO

The growing consumption of ultra-processed foods and beverages has drawn attention to the use of different food additives in these products. The use of these additives for different purposes in food products is permitted under specific legislation. The objective of the present study was to assess the distribution and patterns of occurrence of the different categories of food additives present in packaged foods and beverages sold in Brazil. A descriptive cross-sectional study was conducted based on data from lists of ingredients used in foods and beverages sold in supermarkets in Brazil, collected by photographing product labels. The number, technological purpose and proportion of food additives in 9856 items (25 groups) were assessed. Exploratory factor analysis was employed to derive the patterns of food additive categories. Linear regression models were used to assess the association between the patterns and food items analyzed. Only 20.6% of the products analyzed contained no food additives, while 24.8% contained ≥6 additives. The use of food additives was high, particularly cosmetic additives, predominantly flavoring agents, colorings and stabilizers. Five patterns of food additive categories were identified and associated with ultra-processed foods and beverages. The results revealed that food additives are highly prevalent in several types of food items sold in the Brazilian market. Also, the same additive category was common to several different food groups, as were specific food additive combinations. This exposure is potentially harmful to human health, given the known deleterious effects associated with the consumption of these substances.

RESUMO

The Entomolepididae family is a small taxon with a very characteristic body morphology and is represented, in the Atlantic Ocean, by three genera and five species. A recent study in Todos-os-Santos Bay, in Bahia State, has revealed a new species of Spongiopsyllus and a new species and genus belonging to the Entomolepididae. The new species of Spongiopsyllus is found in association with the sponge Aplysina cauliformis (Carter, 1882) sampled at the Porto da Barra beach. It is distinguished from its congeners mainly by differences in the segmentation pattern of the antennule, endopod of antenna, and the setation of the maxillule, maxilla and maxilliped. The new genus and species from Parmulodinae Eiselt, 1959 is found in association with the sponge Aplysina solangeae Pinheiro, Hajdu Custódio, 2007, sampled at the Yacht Club Beach. The genus differs from others Parmulodinae mainly due to segmentation pattern of the antennule, endopod of antenna, maxilliped and swimming legs.
