ABSTRACT Soil compaction negatively impacts soil physical functions, affecting root growth and crop yield. This study aimed to evaluate different soybean cultivars’ agronomic and physiological performance as a function of compaction in Rhodic Ferralsol under no-tillage (NT) with a clay loam texture in the Brazilian Cerrado biome. The experiment was implemented in Rio Verde, Goias state, central Brazil. The experimental design was a randomized block with a 3x2 factorial scheme with six replications. The first factor corresponded to three soybean cultivars from different maturity groups (MG) identified as super-early (MG = 6.2); early (MG = 6.8), and medium (MG = 7.9). The second factor was the cultivation in compacted and uncompacted soil. The experiment evaluated the soil physical properties: bulk density, total porosity, water content at matric potential -6 kPa, aeration capacity and water and air holding capacity in 0.0-0.1 and 0.1-0.2 m layers, agronomic and physiological traits (gas exchange). Soil compaction negatively affected the agronomic traits of soybean cultivars, with better performance of the medium cycle cultivar. Net photosynthesis, stomatal conductance, and transpiration rates were reduced up to 50% under compaction and were not influenced by cultivars. Our findings suggest that soil compaction negatively affected the performance of soybean cultivars with lower maturity groups reflecting in lower plant height, shoot and root dry mass, number of pods and grain yield. The choice of soybean cultivars with a longer cycle can be an alternative to minimize the adverse effects of soil compaction.

Abstract: In the era of the financialization of capital, the indebtedness of the working class has become a global phenomenon, present in both the central economies and the periphery of capitalism. This article questions the supposed homogeneity of this phenomenon, highlighting the validity of the category of overexploitation of the workforce in order to understand the particular - and highly violent - way in which indebtedness is expressed in Brazil.

Resumo: Na era da financeirização do capital, o endividamento da classe trabalhadora tem se tornado um fenômeno global, presente tanto nas economias centrais, quanto na periferia do capitalismo. Este artigo contesta a pretensa homogeneidade desse fenômeno, evidenciando a vigência da categoria superexploração da força de trabalho para apreensão do modo particular - e altamente violento - com que o endividamento se expressa no Brasil.

ABSTRACT The no-tillage system is a conservation system that helps sustainability and agricultural production. The effectiveness of glyphosate control, applied alone or in combination with other herbicides, can be altered depending on the product’s formulation. The objective of the present study was to evaluate the effectiveness of glyphosate in formulations containing different salts and concentrations, applied alone and in combination with other herbicides, in controlling weeds in advanced stages in the pre-sowing burndown operation. The experiment was carried out in the field in an area with a history of high weed infestation. The experiment was conducted in a randomized block design, evaluating eleven treatments and four replicates. The treatments consisted of the application of three glyphosate-based formulations alone and in combination with clethodim and 2,4-D amine herbicides, in addition to a control without herbicide application. The evaluated variables were percentage of weed control and percentage of desiccation. A comparison of means by contrasts was performed to analyze the percentage of weed control. In general, treatments containing products based on glyphosate potassium salt in the composition have slightly better control performance compared to those consisting of glyphosate isopropylamine salt.

RESUMO O sistema de plantio direto é um sistema conservacionista que auxilia na sustentabilidade e a produção agrícola. A eficácia de controle do glyphosate, aplicado isoladamente ou em associação a outros herbicidas, pode ser alterada em função da formulação do produto. O objetivo do presente trabalho foi avaliar a eficácia de glyphosate em formulações contendo diferentes sais e concentrações, aplicado isolado e em associações a outros herbicidas, no controle de plantas daninhas em estádios avançados na operação de dessecação pré-semeadura. O experimento foi realizado a campo em área com histórico de elevada infestação de plantas daninhas. O experimento foi conduzido no delineamento de blocos casualizados, avaliando-se onze tratamentos e quatro repetições. Os tratamentos foram compostos pela aplicação de três formulações à base de glyphosate isolado e em associações com os herbicidas clethodim e 2,4-D amina, além de uma testemunha sem aplicação. As variáveis avaliadas foram porcentagem de controle das plantas daninhas e porcentagem de dessecação. Foi realizado uma comparação de médias por contrastes para analisar a porcentagem de controle de plantas daninhas. De maneira geral, tratamentos contendo produtos à base de glyphosate sal potássico na composição apresentam performance de controle ligeiramente superior em comparação com àqueles constituídos por glyphosate sal de isopropilamina.

RESUMEN El espaciamiento entre hileras comúnmente utilizado en el cultivo de yuca en Brasil, especialmente en la región de Agreste de Alagoas, varía de 100 a 120cm. Sin embargo, la reducción del espacio entre hileras puede promover ganancias agronómicas y ambientales en los sistemas de cultivo con yuca. Por lo tanto, el objetivo de este trabajo fue evaluar el comportamiento de dos variedades de yuca cultivadas con espaciamiento reducido entre hileras. Se realizaron dos experimentos en el campo, uno en el 2015/16 y otro en el 2017/18. El diseño experimental utilizado en ambos experimentos fue el de Parcelas Divididas con cuatro repeticiones. Se evaluaron cuatro espaciamientos entre filas en la parcela principal: 60, 80, 100 y 120cm, con plantas espaciadas 60cm dentro de las hileras, dando poblaciones de 27,778, 20,833, 16,667 y 13,889 plantas por hectárea, respectivamente. En las subparcelas se evaluaron dos variedades de yuca: Caravela y Pretinha. Un aumento en el espaciamiento entre hileras promovió una reducción lineal en la masa verde del tallo de la yuca. La altura de la planta, la masa verde de la hoja, el diámetro del tallo principal, el rendimiento de la raíz, la longitud de la raíz tuberosa, el diámetro de la raíz tuberosa, el porcentaje de harina, el rendimiento de la harina y el contenido de almidón no se vieron afectados por los cambios en el espaciamiento entre hileras. La variedad Pretinha fue superior a Caravela en las siguientes características evaluadas: masa verde del tallo, diámetro de raíces tuberosas, rendimiento de raíces, altura de planta y rendimiento de harina. Los resultados indican la posibilidad de alterar el espaciamiento entre hileras en la yuca para ayudar en el manejo cultural, sin afectar el rendimiento del cultivo.

ABSTRACT The interrow spacing commonly used in cassava cultivation in Brazil, especially in the Agreste region of Alagoas, ranges from 100 to 120cm. However, the reduction in row spacing can provide agronomic and environmental benefits in cassava cropping systems. Thus, this work aimed to evaluate the performance of two cassava varieties cultivated with reduced interrow spacing. Two experiments were conducted in the field, one in 2015/16 and another in 2017/18. A Split Plot design with four replications was used in both experiments. Four interrow spacing were evaluated in the main plot: 60, 80, 100 and 120cm, with plants spaced 60cm apart within rows, giving populations of 27,778, 20,833, 16,667 and 13,889 plants per hectare, respectively. In the subplots, two cassava varieties were evaluated: Caravela and Pretinha. An increase in interrow spacing promoted a linear reduction in the stem green mass of cassava. Plant height, leaf green mass, main stem diameter, root yield, tuberous root length, tuberous root diameter, flour percentage, flour yield, and starch content were not influenced by changes in interrow spacing. The Pretinha variety was superior to Caravela in the following evaluated traits: stem green mass, the diameter of tuberous roots, root yield, plant height, and flour yield. The results indicate the possibility of altering the interrow spacing in cassava to assist in the cultural management, without impacting crop yield.

Abstract Objective: This study assessed the efficacy of two adjunct therapies (antibiotic and probiotic) for periodontal treatment based on clinical and immunological parameters in patients with Stage II and III Grade B periodontitis. Methodology: 45 patients were randomly allocated into three groups: control group (CG); antibiotic group (GAtb), in which 500 mg amoxicillin + 400 mg metronidazole were used; and probiotic group (GProb), for which Lactobacillus reuteri was used. Patients received medications after undergoing periodontal debridement. Clinical and immunological parameters were assessed at baseline, 30 days, and 90 days. Results: All therapies reduced bleeding on probing (BoP) in the evaluated periods, and the GAtb had a greater reduction at 90 days (p=0.03). The GProb group showed better results for plaque index (PI) and gingival recession (GR) compared to the GAtb at 90 days (p=0.0014; p=0.006). The area of inflammation (PISA Index) significantly decreased in all therapies in the evaluated periods. Therapies had no significant differences regarding moderate pockets. The GAtb had a greater reduction in probing depth (PD) for deep pockets (p=0.03) at 90 days and in the number of deep pocket sites at 30 days (p=0.04). The occurrence of adverse effects was commonly reported in the GAtb as a percentage per patient. The GAtb had a significant reduction in the concentration of interleukins IL-1β and IL-8 and an increase in IL-10 and TNF-α. The CG had a reduction in IL-6 and IL-1 β, whereas in the GProb there was no difference. Conclusion: After three months, none of the adjuvant therapies provided any additional benefit for subgingival instrumentation.

ABSTRACT. The succession of soybean/maize has been largely adopted. Storm damage and crop problems can lead to grain loss, generating maize ear fragments or even whole ears that remain in the soil and still display germination viability, resulting in the occurrence of volunteer plants. In this context, the present study aimed to evaluate the interference of voluntary maize plants on soybean and investigate the susceptibility of maize hybrids to pre-emergence herbicides. In the first step, an experiment was performed evaluating the influence of voluntary maize plant density and spatial distribution on soybean. The experiment was performed in a randomized completely block design (RCBD) with four replications, with treatments disposed in factorial arrangement (2 x 4) + 1. The first factor corresponded to the spatial distribution of maize plants: row or in between soybean rows; while the second factor adopted four infestation densities of maize plants m-2: 4, 8, 12, and 16. The additional treatment consisted of a control without maize plants. For the second step, an experiment was conducted in two locations aiming to determine the efficacy of pre-emergence herbicides in the control of voluntary maize. Both experiments were installed in RCBD in a split-plot scheme with four replications. Fomesafen, lactofen, sulfentrazone, chlorimuron-ethyl, diclosulam, flumetsulam, imazethapyr, clomazone, metribuzin, [sulfentrazone + diuron], [imazethapyr + flumioxazin], and a control without herbicide application were evaluated in the main plot. In each subplot, the maize hybrids DKB310 PRO3™ and DKB390 PRO3™ were evaluated. No influence on the position of voluntary maize on the soybean yield was observed. The presence of the maize population led to a progressive decrease in soybean yield, ranging up to 86%, at 16 plants m-2. DKB390 displayed a stand reduction of 82.88% after the use of diclosulam. Diclosulam led to better results regarding maize plant decreases for both hybrids.

ABSTRACT OBJECTIVE To evaluate the performance of post mortem laboratory analysis in identifying the causes of hemorrhagic fever and/or neuroinvasive disease in deaths by arbovirus infection. METHODS Retrospective cross-sectional study based on the differential analysis and final outcome obtained in patients whose samples underwent laboratory testing for arboviruses at the Pathology Center of the Adolfo Lutz Institute, in São Paulo, Brazil. RESULTS Of the 1355 adults clinically diagnosed with hemorrhagic fever and/or neuroinvasive disease, the most commonly attributed cause of death and the most common final outcome was dengue fever. Almost half of the samples tested negative on all laboratory tests conducted. CONCLUSION The failure to identify the causative agent in a great number of cases highlights a gap in the diagnosis of deaths of unknown etiology. Additional immunohistochemical and molecular assessments need to be added to the post-mortem protocol if all laboratory evaluations performed fail to identify a causative agent. While part of our findings may be due to technical issues related to sample fixation, better information availability when making the initial diagnosis is crucial. Including molecular approaches might lead to a significant advancement in diagnostic accuracy.

El meme, un fenómeno cultural en el siglo XXI, se caracteriza como una forma de comunicación colectiva y paródica basada en la recreación excesiva y una propagación viral. Esta forma de expresión, por su alcance, ha sido apropiada por las organizaciones como una forma innovadora de difundir mensajes, vender productos, servicios o ideas. Teniendo en cuenta la importancia de destacar, estas características son un factor relevante para las organizaciones porque, en un escenario de sobrecarga de información, el acceso a la mayor cantidad de personas posible es estratégico. Sin embargo, a pesar de la posibilidad de su uso en la organización, es necesario que el meme tenga una imagen institucional, lo que requiere el cumplimiento de ciertos requisitos para reforzar la marca de la institución sin dañar los aspectos éticos. En este sentido, el presente artículo buscó destacar una actividad de marketing institucional desarrollada por un grupo de investigación que utilizó el meme como estrategia de difusión debido a su potencial simbólico. El resultado obtenido en la campaña llevada a cabo se tradujo en un aumento exponencial en el número de seguidores de la página que se destaca de las otras publicaciones del grupo en la red social digital utilizada.

O meme, fenômeno cultural no século XXI, é caracterizado como uma forma de comunicação coletiva, paródica e baseada em uma recriação repetida de maneira contínua, composta por diferentes formulações baseadas sempre numa mesma estrutura, que se espalha de modo viral. Essa forma de expressão, por seu alcance, foi apropriada pelas organizações como modo inovador de divulgar mensagens, vender produtos, serviços ou ideias. Considerando a importância de se estar em destaque, estas características são um fator relevante para as organizações porque, em um cenário de excesso informacional, ser acessado pelo maior número possível de pessoas é estratégico. Contudo, apesar da possibilidade de sua utilização no ambiente organizacional, existe a necessidade do meme se revestir de uma imagem institucional, o que requer a observância de certos quesitos para reforçar a marca da instituição sem ferir aspectos éticos. Neste sentido, o presente artigo buscou destacar uma atividade de marketing institucional desenvolvida por um grupo de pesquisa que utilizou o meme como estratégia de divulgação devido ao seu potencial simbólico. O resultado obtido na campanha realizada se traduziu em um aumento exponencial do número de seguidores da página destacando-se das demais postagens do grupo na rede social digital utilizada.

The meme, a cultural phenomenon in the 21st century, is characterized as a form of collective communication, parodic and based on an excessive recreating that spreads virally. This form of expression, by its reach, was appropriated by organizations as an innovative way to spread messages, sell products, services, or ideas. Considering the importance of being in a highlighted position, these characteristics are a relevant factor for organizations because, in a scenario of information overload, being remembered / accessed by as many people as possible becomes strategic. However, despite the possibility of its use in the organizational environment, there is a need for the meme to have an institutional image, which requires compliance with certain requirements to reinforce the institution’s brand without hurting ethical aspects. In this sense, the present article sought to highlight an institutional marketing activity developed by a research group that used the meme as a dissemination strategy due to its symbolic potential. The result obtained in the campaign translated into an exponential increase in the number of followers of the page in the digital social media used, standing out from the other posts of the group.

ABSTRACT Weed management consists of a fundamental practice in cassava, with mechanical and chemical control widely used. The objective of this work was to evaluate the efficacy of pre-emergence herbicides, as well as to determine the interaction of these with weeding complementation in the weed management in cassava. Two experiments were conducted in Junqueiro (Alagoas). In 2015/16, the experimental design was based on randomized blocks, with treatments distributed in a split-split-plot scheme, with four replications. In the main plot, four pre-emergence associations of clomazone + flumioxazin in different doses were evaluated, in addition to a control without herbicide. In the subplots, the Caravela and Pretinha cassava cultivars were evaluated, while in the sub-subplots the control complementation was evaluated using or not the manual weeding. In the 2016/17, the plot design and layout remained the same as for 2015/16, except for the composition of the herbicide treatments, since the standardization of clomazone dose has been chosen, varying only the doses of flumioxazin. The association of clomazone and flumioxazin has shown efficacy in weed control, with a greater residual as higher doses are used. This association provided higher shoot and root yield. Weeding complementation along the cassava cycle can increase its yield.

RESUMO A disposição espacial em que plantas se encontram na área de cultivo é fator que influencia diretamente na produtividade de grãos, pois o melhor arranjo entre essas pode resultar em maior aproveitamento de água, luz e nutrientes. O objetivo do trabalho foi avaliar o desempenho agronômico de sorgo semeado em espaçamento de fileiras duplas no Cerrado. Para tanto, foi conduzido nas safrinhas de 2018 e 2019, experimentos de campo em delineamento de blocos completos em esquema fatorial 2 x 5, com quatro repetições, em que se utilizou dois espaçamentos de entrelinhas de semeadura: tradicional (0,50 m) e fileiras duplas (0,25 m/0,75 m) e cinco populações de plantas: 120, 180 (recomendada), 240, 300 e 360 mil plantas ha-1. Foram avaliadas características morfológicas, componentes do rendimento e produtividade de grãos utilizando análise conjunta dos dados para os dois anos de estudo. Em 2018, devido ao menor volume de chuvas durante o ciclo da cultura, a utilização do arranjo em fileiras duplas apresentou produtividade de grãos inferior ao espaçamento tradicional. Por outro lado, em 2019, ano com melhor distribuição hídrica, a produtividade foi superior a 2018. O aumento da população de plantas por hectare incrementou a produtividade de grãos de sorgo, com ganhos de até 24% em relação à população recomendada de 180 mil plantas ha-1, demonstrando que o adensamento nessa cultura pode ser uma técnica promissora desde que levado em consideração seu custo/benefício.

ABSTRACT The spatial arrangement of plants in the cultivation area is a factor that directly influences grain yield, since the best arrangement can result in the greater use of water, light and nutrients. The aim of the study was to evaluate the agronomic performance of sorghum sown in double row spacing in the Brazilian Cerrado. For this purpose, field experiments were conducted in the 2018 and 2019 seasons in a complete block design with a factorial scheme of 2 x 5. There were four replications, using two row spacing: traditional (0.50 m) and double rows (0.25 m/0.75 m) and five plant populations: 120, 180 (recommended), 240, 300 and 360 thousand, plants ha-1. Morphological characteristics, yield components and grain yield were evaluated using joint data analysis for the two years of study. In 2018, due to lower rainfall during the crop season, the use of a double row arrangement presented grain yield lower than traditional spacing. On the other hand, in 2019, the year with the best water distribution, the yield was superior to that of 2018. The increase in plant population per hectare increased the yield of sorghum grains, with gains of up to 24% in relation to the recommended population of 180 thousand plants ha-1, demonstrated that the densification in this crop can be a promising technique as long as its cost/benefit is considered.

RESUMO O consórcio de sorgo granífero com braquiária proporciona a produção de grãos e massa seca na entressafra; contudo, há carência de informações relacionadas à implantação dessas espécies. Sendo assim, este trabalho teve por objetivo identificar a melhor associação de sorgo granífero e braquiária na segunda safra para produção de grãos e massa seca na região do Cerrado. O experimento foi conduzido em Rio Verde, Goiás, no delineamento experimental de blocos randomizados, em esquema fatorial 2×3×4+5, com quatro repetições. Foram avaliados dois híbridos de sorgo granífero (BRS 330 e DKB 551) associados a três espécies de Brachiaria (Brachiaria brizantha cultivar Marandu, Brachiaria decumbens e Brachiaria ruziziensis) em quatro sistemas de implantação da braquiária (linha, entrelinha, linha + entrelinha do sorgo e a lanço). Os tratamentos adicionais referiam-se aos dois monocultivos de sorgo e às três espécies de braquiária. O consórcio de sorgo com braquiária ocasionou redução no rendimento de grãos, porém os sistemas de implantação da braquiária na linha, entrelinha e a lanço foram os mais promissores. O híbrido de sorgo DKB 551 foi o mais sensível à competição com a braquiária, sem, contudo, haver diferenças de rendimento de grãos em consórcio. Os consórcios das braquiárias na entrelinha e na linha + entrelinha, principalmente com a B. ruziziensis, foram os mais promissores para produção de massa seca e proteína bruta total. O cultivo de braquiária com o sorgo proporcionou maior aporte de massa seca na entressafra, fato importante para o sistema de plantio direto nos sistemas de produção agrícola dos Cerrados.

ABSTRACT The grain sorghum intercropped with Brachiaria provides the production of grains and dry mass in the off-season; however, there is a lack of information related to the implantation of these species. The objective of this study was to identify the best association of sorghum and Brachiaria in the production of grain and dry matter in the Brazilian Cerrado region. The experiment was conducted in Rio Verde, State of Goiás, in the experimental design of randomized blocks, in a 2×3×4+5 factorial scheme, with four replications. Two sorghum hybrids (BRS 330 and DKB 551) associated to three Brachiaria species (Brachiaria brizantha cultivar Marandu, Brachiaria decumbens and Brachiaria ruziziensis) were evaluated in four systems of Brachiaria implantation (row, interrow, row + interrow of sorghum and spread). Additional treatments referred to the two sorghum monocrops and the three Brachiaria species. The sorghum and Brachiaria consortium resulted in a reduction in grain yield, but the Brachiaria implantation systems in the row, interrow and spread were the most promising. The sorghum hybrid DKB 551 was the most sensitive to the competition with Brachiaria, although there were no grain yield differences in the intercropping. The Brachiaria intercropped in the interrow and in the row + interrow, mainly with B. ruziziensis, were the most promising for the production of dry mass and total crude protein. The cultivation of Brachiaria intercropped with sorghum provided a greater contribution of dry mass in the off-season, an important fact for the no-tillage system in the agricultural production systems of the Brazilian Cerrado.

Abstract Objective To compare two corticotomy surgical protocols in rats to verify whether they alter conventional orthodontic movement. Methodology Sixty Wistar rats were divided into three groups – orthodontic movement (CG), orthodontic movement and corticotomy (G1) and orthodontic movement with corticotomy and decortication (G2) – and euthanized after 7 and 14 days. Tooth movement (mm), bone volume fraction and bone volume ratio to total volume (BV/TV), and bone mineral density (BMD) were evaluated by micro-CT. The total amount of bone was measured in square millimeters and expressed as the percentage of bone area in the histomorphometry. The number of positive TRAP cells and RANK/RANKL/OPG interaction were also investigated. Results Day 14 showed a statistically significant difference in orthodontic tooth movement in CG compared with G1 (7.52 mm; p=0.009) and G2 (7.36 mm; p=0.016). A micro-CT analysis revealed a difference between CG, G1 and G2 regarding BV/TV, with G1 and G2 presenting a lower BV/TV ratio at 14 days (0.77 and 0.73 respectively); we found no statistically significant differences regarding BMD. There was a difference in the total amount of bone in the CG group between 7 and 14 days. At 14 days, CG presented a significantly higher bone percentage than G1 and G2. Regarding TRAP, G2 had more positive cells at 7 and 14 days compared with CG and G1. Conclusion Corticotomy accelerates orthodontic movement. Decortication does not improve corticotomy efficiency.

RESUMO Objetivo: Descrever a idade mediana de introdução e consumo regular de alimentos por crianças menores de 24 meses em unidades da Estratégia Saúde da Família. Métodos: Estudo transversal realizado com 283 crianças selecionadas por amostragem por conglomerado estratificada uniforme. Foram coletados dados sociodemográficos da mãe e do consumo alimentar da criança (idade de introdução e frequência semanal). Os alimentos foram agrupados em: in natura/minimamente processados (G1); ingredientes culinários (G2); processados (G3) e ultraprocessados (G4). Utilizou-se análise de sobrevida para definição da idade mediana de introdução dos alimentos e teste do qui-quadrado para comparação da frequência de consumo segundo a faixa etária (0 a 5,9; 6 a 11,9; e 12 a 23,9 meses). Resultados: A duração mediana do aleitamento materno exclusivo foi de três meses e do aleitamento materno, de 19 meses. A mediana de introdução dos alimentos do G1 foi de seis meses, exceto para ovo, leite e café (12 meses). Para óleo e sal (G2), a mediana foi de 6 meses e para o açúcar (G2), de sete meses. A mediana da maioria dos alimentos do G4 foi de 12 meses, para fórmulas foi de sete meses, biscoitos e alimentos infantis, oito meses. A maioria dos alimentos ainda não tinha sido introduzida para crianças menores de seis meses. Para crianças de seis a 11,9 meses, o consumo regular (≥5 dias/semana) de G4 foi superior para biscoitos (23,8%), pão (21,2%), fórmulas (21,2%) e alimentos infantis (35,0%); e para crianças de 12 a 23,9 meses foi para biscoitos (31,2%), pão (57,5%) e alimentos infantis (48,7%). Conclusões: Os alimentos introduzidos e consumidos regularmente foram principalmente alimentos in natura, em todas as idades. Alimentos processados e ultraprocessados apresentaram maior frequência de consumo após os 12 meses.

ABSTRACT Objective: To describe the median age of introduction and regular food intake by young children in units of the Family Health Strategy. Methods: Cross-sectional study with 283 young children chosen by uniform stratified cluster sampling. Socio-demographic data on the mother and the child’s food intake were collected (age of food introduction and weekly frequency). Foods were grouped into in natura/minimally processed (G1); culinary ingredients (G2); processed (G3) and ultra-processed (G4). The survival analysis was applied to define the median age of food introduction and the chi-square test was used to compare the frequency of food intake, according to the age range (0-5.9; 6-11.9; and 12-23.9 months old). Results: The median duration of exclusive breastfeeding and breastfeeding were three and 19 months, respectively. The age of median food introduction of G1 was six months, except for eggs, milk and coffee (12 months). For oil and salt (G2), the median was 6 months, and for sugar (G2), seven months. The median age of introduction of most food of G4 was 12 months; for infant formulas, it was seven months; cookies and baby food, eight months. Most food had not yet been introduced for children under six months old. For children from six to 11.9 months old, the regular consumption of G4 (≥5 days/week) was higher for cookies (23.8%), bread (21.2%), infant formulas (21.2%) and baby food (35%); and for children from 12 to 23.9 months old, it was higher for cookies (31.2%), bread (57.5%) and baby food (48.7%). Conclusions: Food introduced and consumed on a regular basis was mainly in natura, at all ages. Processed and ultra-processed food presented a higher frequency of consumption after 12 months old.

RESUMO Objetivo: Comparar e analisar o consumo de alimentos minimamente processados e ultraprocessados entre escolares das redes pública e privada. Métodos: Estudo realizado em Uberlândia, MG, com escolares do quinto ano do ensino fundamental em nove escolas (três privadas e seis públicas), selecionados por amostragem estratificada por conglomerado. O consumo alimentar foi analisado utilizando recordatório de 24 horas. Os alimentos foram classificados segundo extensão e propósito do seu processamento em quatro grupos (G): alimentos in natura/minimamente processados (G1), ingredientes culinários (G2), alimentos processados (G3) e ultraprocessados (G4). Os valores energéticos totais (kcal) provenientes de cada grupo, quantidade de açúcar (g), sódio (mg) e fibras (g) foram quantificados e comparados segundo dependência administrativa. Resultados: O consumo de energia foi: G1, 52%; G2, 12%; G3, 5%; e G4, 31%. Os valores energéticos provenientes de G1 (53 vs. 47%), G2 (12 vs. 9%) e G3 (6,0 vs. 0,1%), a quantidade de sódio (3.293 vs. 2.724 mg) e a de fibras (23 vs. 18 g) foram superiores em escolares da rede pública. O valor percentual energético do G4 (36 vs. 28%) e a quantidade de açúcar (20 vs. 14%) foram superiores em escolares da rede privada. O consumo do G1 na escola foi superior nos escolares da rede pública (40 vs. 9%). Conclusões: Alimentos do G1 representam o maior percentual do valor energético total e do G4, um terço das calorias ingeridas. Suco pronto, biscoito recheado, bolo industrializado, cereais matinais são mais frequentes em escolares da rede privada e salgadinhos e suco em pó nos da rede pública.

ABSTRACT Objective: To compare and analyze the consumption of minimally processed and ultra-processed foods among students from public and private schools. Methods: Study conducted in Uberlândia, MG, with fifth-grade students from three private and six public schools, selected by stratified cluster sampling. We collected data on food consumption using the 24-hour recall. Foods were classified into four groups (G) according to extent and purpose of processing: fresh/minimally processed foods (G1) culinary ingredients (G2), processed foods (G3), and ultra-processed foods (G4). Total energy intake (kcal) of each group, amount of sugar (g), sodium (mg), and fiber (g) were quantified and compared according to administrative affiliation (private or public). Results: Percentage of total energy intake was: G1 - 52%; G2 - 12%; G3 - 5%; e G4 - 31%. Energy intake from G1 (53 vs. 47%), G2 (12 vs. 9%), and G3 (6.0 vs. 0.1%), and amount of sodium (3,293 vs. 2,724 mg) and fiber (23 vs. 18 g) were higher among students from public schools. Energy intake from G4 (36 vs. 28%) and amount of sugar (20 vs. 14%) were higher among students from private schools. The consumption of foods from G1 in the school environment was higher among students from public schools (40 vs. 9%). Conclusions: Foods from G1 represent the highest percentage of total energy intake, while those from G4 constitute a third of calories consumed. Processed juice, sandwich cookie, processed cake, and breakfast cereals are more frequent among private school students; snacks and juice powder are more common for students from public schools.
