Abstract (Introduction): Within the framework of the present capitalist system, human beings have become an important polluting agent. Current production and consumption processes do not consider the existence of finite natural resources and a planet incapable of treating the waste that the prevailing way of life generates. Given these circumstances, the study of non-linear models is of interest, which make a more rational use of the waste that the productive activity generates, favoring recycling mechanisms. The phenomenon of recycling becomes particularly relevant in the case of electrical and electronic devices, whose ability to be degraded and metabolized by planet Earth is extremely difficult. (Objective): Evaluate the feasibility of installing and starting a recycling plant for electrical and electronics items in the town of Bahía Blanca (Argentina), during 2021. (Methodology): The conventional method for evaluating investment projects was used, considering technical, legal and economic aspects. (Results): The project is not acceptable according to the profitability intended by the investor. The possibility of financing was also included, which made the project even less profitable, and the sensitivity of the results was measured, finding that the price should be 1.48 % higher than that used in the analysis. (Conclusions): Other alternatives must be explored to make this proposal profitable from an economic and financial point of view.

Resumen (Introducción): En el marco del sistema capitalista vigente, el ser humano se ha transformado en un agente significativo de contaminación. Las dinámicas productivas y de consumo actuales no contemplan la existencia de recursos naturales finitos y de un planeta incapaz de procesar los desperdicios que el modo de vida habitual genera. Dadas estas circunstancias, cobra interés el estudio de modelos no lineales, que hagan un uso más racional de los residuos derivados de la actividad productiva, los cuales favorezcan mecanismos de reciclaje. El fenómeno del reciclaje se vuelve, en particular, relevante para el caso de los artefactos eléctricos y electrónicos; la capacidad del planeta Tierra para degradarlos y metabolizarlos resulta sumamente difícil. (Objetivo): Evaluar la factibilidad de la instalación y puesta en marcha de una planta recicladora de artículos eléctricos y electrónicos en la localidad de Bahía Blanca (Argentina), durante el 2021. (Metodología): Se utilizó la metodología convencional de evaluación de proyectos de inversión, considerando aspectos técnicos, legales y económicos. (Resultados): El proyecto no es aceptable según la rentabilidad pretendida por el inversor. También se incluyó la posibilidad de un financiamiento, lo que hizo que el plan fuera menos rentable aún, y se midió la sensibilidad de los resultados: se halló que el precio debiera ser 1.48 % superior al utilizado en el análisis. (Conclusiones): Se deben explorar otras alternativas para lograr que el proyecto sea rentable desde el punto de vista económico-financiero.

With the increase in life expectancy and the significant incidence of lesions of the musculoskeletal system, both the public and private sectors seek improvements in their products and processes in order to contribute to the health of the population. Every year tons of chicken eggshell (CES) from domestic consumption are released in environment and the present work aims the production of a synthetic ceramic bone substitute using the eggshell as a source of calcium ions. According to the methodology, 5, 10, 15 and 20 mol% of iron ions were used and the characterization assays demonstrated the formation of a double calcium iron phosphate - Ca9Fe(PO4)7. MG63 cells were cultured on test specimens to cell viability assay and to each doped group analyzed, verifying cell compatibility with the studied compounds, as well as a good adhesion profile. Scanning electron microscopy (SEM) of the cells showed that material surface favored cell adhesion and the results demonstrated that the production of the compounds were viable to Ca9Fe(PO4)7 phase. So, in the future, it will be possible to have a final comprehensive biological compatibility of the prototype for further in vitro and in vivo assays. system population CES (CES methodology 5 10 1 2 mol Ca9FePO47.

RESUMO O consumo de dióxido de carbono atmosférico pelo intemperismo tampona o efeito estufa na Terra em escala de tempo geológica. Esse mecanismo é chamado de sumidouro de carbono de silicato (SCS). Saprolito representa parte da frente de intemperismo do manto terrestre, mas historicamente não recebeu muita atenção dos geocientistas. Em escala global, o Brasil é o maior contribuinte para o SCS e o quarto maior contribuinte em número de publicações sobre saprolito. Neste estudo, a produção científica brasileira sobre o assunto de 1990 a 2022 foi avaliada, considerando publicações indexadas nas bases de dados Web of Science, SciELO e Scopus. Foram recuperados cento e oitenta artigos científicos. Na última década, sete artigos foram publicados por ano. Ao longo dos 32 anos considerados, o número de artigos sobre saprolito aumentou. A maioria dos estudos foi concentrada na região sudeste do Brasil, onde o estado de Minas Gerais liderou em termos de número de publicações (28,49%). As principais áreas em que os artigos foram publicados estavam relacionadas à ecologia, Terra e marinha; no entanto, foram citados por várias outras, incluindo as áreas de saúde e política. Uma comparação do número de publicações por bacia e o tamanho do SCS mostrou que havia menos estudos da Bacia Amazônica do que da Bacia do Paraná. Em conclusão, a fronteira geográfica para o estudo do saprolito no território brasileiro é a Bacia do Rio Amazonas, e a fronteira metodológica está relacionada à dinâmica de fluídos/gases e ao papel dos micróbios no intemperismo em profundidade. geológica SCS. .

ABSTRACT The consumption of atmospheric carbon dioxide by weathering buffers the greenhouse effect on Earth on a geological timescale. This mechanism is called the silicate carbon sink (SCS). Saprolite represents part of the weathering front of the Earth’s mantle, but historically, it has not received much attention from geoscientists. On a global scale, Brazil is the largest contributor to the SCS and the fourth largest contributor to the number of saprolite publications. In this study, Brazilian scientific production on the subject from 1990 to 2022 was assessed, considering publications indexed in the Web of Science, SciELO and Scopus databases. One hundred-eighty scientific articles were retrieved. In the last decade, seven articles were published per year. Over the 32 years under consideration, the number of articles on saprolite has increased. Most of the studies were concentrated in the southeastern region of Brazil, where the state of Minas Gerais led in terms of the number of publications (28.49%). The main areas in which the articles were published were related to ecology, Earth, and marine; however, they were cited by several others, including the areas of health and politics. A comparison of the number of publications per basin and the size of the SCS showed that there were fewer studies from the Amazon Basin than from the Paraná Basin. In conclusion, the geographical frontier for the study of saprolite in the Brazilian territory is the Amazon River Basin, and the methodological frontier is related to fluid/gas dynamics and the role of microbes in weathering at depth. timescale SCS. .

ABSTRACT The correct use of tyres on agricultural tractors, in respect of the terrain and the type and internal pressure of the tyre, are factors that influence the performance of the tractor. The aim of the present study was to evaluate the operating performance of an agricultural tractor fitted with two types of traction device (radial and diagonal tyres) at different pressures, and operating on soil with two levels of moisture. The experiment was conducted on a dystrophic Red Yellow Argisol, with tests to evaluate the performance of the tyres under specific working conditions. Tractive power and tractive force, wheel slip and fuel consumption were evaluated. For each of the conditions under evaluation, the radial configuration showed better performance than the diagonal configuration, the effect being more significant at the lower pressure and under low soil moisture. The use of radial tyres led to an increase in traction capacity and drawbar power, with a reduction in fuel consumption, especially at higher slip rates. tractors tyre pressures moisture Argisol force evaluated evaluation rates

Brazilian Savanna biodiversity is abundant in native fruits with nutritional and sensory properties with potential technological applications. However, the information available regarding the proprieties of Brazilian native fruits is still limited. This study aimed to analyze the metabolic profile of Brosimum gaudichaudii fruits (BGF) using metabolomics approaches, besides its physicochemical and nutritional proprieties. BGF exhibited protein content at least two times higher than other native fruits. Fifty-five metabolites were identified by the metabolomics approaches, mainly fatty acids (n = 22), carbohydrates (n = 13), organic acids (n = 6), and polyphenols (n = 5). The most abundant constituents were D-fructose (42.97%) for sugars, L-asparagine (6.47%) for amino acids, succinic acid (44.11%) for organic acids, and linolenic acid (3.04%) for fatty acids. Highlighted phytochemicals included chlorogenic acid, α-amyrin, and γ-tocopherol. Additionally, this study revealed that BGF is a good source of vitamin C and dietary fiber and an excellent source of vitamin A. Future studies providing nutritional information and suggesting consumption methods and potential industrial applications are essential to familiarize consumers with these foods. Additionally, clarifying the appropriate planting and harvesting seasons can revive traditional practices, especially for native fruits like BGF.

Even though ammonia is a natural component of aquatic environments, elevated concentrations indicate pollution and environmental degradation. Consequently, efficient analytical methods for monitoring ammonia levels are crucial for preserving water quality. Voltammetry offers a sustainable approach for NH3 quantification, combining good analytical performance with low sample and reagent consumption, minimizing waste generation. However, despite these advantages, the voltammetric determination of ammonia remains relatively unexplored. Therefore, this study investigated the electrochemical behavior of NH3 in alkaline solutions using a non-modified Pt electrode and evaluated the performance of differential pulse voltammetry (DPV) and square wave voltammetry (SWV) for NH3 determination. DPV provided superior performance, with limits of detection and quantification of 0.79 µmol L-1 (0.011 ppmN) and 2.6 µmol L-1 (0.036 ppmN), respectively, which comply with the maximum allowable ammonia concentration in natural waters according to Brazilian and European regulations. The voltammetric method successfully quantified ammonia in tap and river water samples, providing results concordant with the established Berthelot spectrophotometric method, at a 95% confidence level. Additionally, it is simple and fully accessible to non-electrochemist since no sophisticated procedures for electrode modification are needed. Finally, the high analytical performance of the proposed method makes it valuable for pollution monitoring in aquatic environments. environments degradation Consequently quality NH consumption generation However advantages unexplored Therefore nonmodified non modified (DPV SWV (SWV 079 0 79 0.7 L1 L 1 L- 0.011 0011 011 (0.01 ppmN 26 2 6 2. 0.036 0036 036 (0.03 ppmN, , respectively regulations samples 95 level Additionally nonelectrochemist electrochemist needed Finally 07 7 0. 0.01 001 01 (0.0 0.03 003 03 9 0.0 00 (0.

Groundwater is considered an important source of water aid for human consumption. However, this water can be contaminated by impurities, such contamination spots that might reach the water tables. The aim of this study was to investigate the quality of shallow groundwater in Flores neighborhood, located in the municipality of Benevides, within Belém metropolitan region, State of Pará, Brazil. Recommendations described in Standard Methods for Examination of Water and Wastewater were followed at the time to determine physical-chemical parameters such as potential hydrogen (pH), electrical conductivity (EC), total dissolved solids (TDS), apparent color, turbidity, total hardness (TH), ions and trace elements. Multivariate statistical analysis has shown that most predictive water-quality parameters set for human consumption are associated with natural events involving weathering and leaching processes. Nevertheless, parameters of nitrate, phosphate, EC, TDS and pH are also influenced by anthropic conditions in the surroundings, mainly phosphate and nitrate ions. Therefore, it can be concluded that shallow groundwaters in Flores neighborhood are unsuitable for human consumption, making it necessary for municipal public authorities to take action to solve the problem of water shortage in the borough, thus preventing the population from use those shallow groundwaters, as their consumption can bring health problems. However impurities tables Benevides region Pará Brazil physicalchemical physical chemical pH, , (pH) EC (EC) TDS, (TDS) color turbidity TH, TH (TH) elements waterquality processes Nevertheless surroundings Therefore borough problems (pH (EC (TDS (TH

ABSTRACT This article proposes a conceptual model to assess how consumers' materialistic motivations impact social characteristics (prestige and conspicuity) that generate status for innovative technological products, which can lead to consumption intention. The study used a quantitative approach to test a conceptual model using structural equation modeling through PLS - SEM. The results indicate that product prestige and perception of product conspicuity mediate consumers’ materialistic motivations, which affects the social status provided to the individual by the product. Likewise, perception of innovation and product status mediate the relationship between conspicuity and perceived prestige in relation to consumption intention. This research yields important insights regarding the strong relations between the social characteristics of technological products that take into account individuals’ values. Consequently, this study enhances understanding of how status and social value influence the intention to consume technological products, demonstrating the extent to which innovation brings elements of value to individuals who own the product in question. consumers SEM Likewise values Consequently question

ABSTRACT The search for new technologies capable of providing benefits to healthy eating is a global goal. The consumption of foods rich in carotenoids can prevent serious health problems. Thus, the availability of foods high in carotenoids that are accessible to the majority of the population is essential. Lettuce (Lactuca sativa L.) is a suitable species for biofortification research based on genetic improvements. In this study, we aimed to select and obtain hybrid lettuce populations with high agronomic potential and biofortified carotenoid content. Ten lettuce lines registered in the “BG α Biofort” software were selected for hybridization. The crosses used to obtain the hybrids involved two strains rich in at least one of the pigments (chlorophyll and carotenoids), and 24 experimental hybrids were obtained. A total of 37 genotypes (strains, hybrids, and commercial cultivars) were evaluated using a randomized block design for agronomic variables and chlorophyll and carotenoid content. Hybrids 12 (UFU-189#3#4#1 × UFU MC BIOFORT 2) and 25 (UFU66#4#2 × UFU-189#3#4#1) had the potential to produce dual-purpose populations (yield and carotenoid biofortification). Hybrid 27 (UFU66#4#2 × UFU MC BIOFORT1) exhibited the best pigment balance. Thus, F2 hybrids 12, 25, and 27 should be obtained to produce new cultivars of biofortified red and green lettuce for curly, american, mini, and romaine lettuce segments. goal problems Thus essential Lactuca L.

RESUMO A busca por novas tecnologias capazes de proporcionar benefícios para uma alimentação saudável tem sido meta mundial. A presença de alimentos ricos em carotenoides pode ser fundamental para prevenir sérios problemas de saúde. Aliar alimentos com altos teores de carotenoides e acessíveis para a maior parte da população é fundamental. A alface (Lactuca sativa L.) se apresenta como uma espécie adequada para investir em pesquisas com biofortificação a partir de melhoramento genético. Assim, o objetivo com este estudo foi selecionar híbridos de alface visando à obtenção de populações com potencial agronômico e biofortificadas para carotenoides. Dez linhagens de alface cadastradas no Software “BG α Biofort” foram utilizadas nas hibridações. Os cruzamentos para obtenção dos híbridos foram planejados envolvendo duas linhagens ricas em pelo menos um dos pigmentos (clorofila e carotenoides) sendo obtidos 24 híbridos experimentais. Foram avaliados 37 genótipos (linhagens, híbridos e cultivares comercias) em delineamento em blocos casualizados quanto as variáveis agronômicas e teores de clorofila e carotenoides. Foi verificado que os híbridos 12 (UFU-189#3#4#1 × UFU MC BIOFORT 2) e 25 (UFU66#4#2 × UFU-189#3#4#1) possuem potencial para obtenção de populações de duplo propósito (produtividade e biofortificada para carotenoide). O híbrido 27 (UFU66#4#2 × UFU MC BIOFORT1) foi o que apresentou maior equilíbrio para pigmentos. Sugere-se a obtenção de populações F2 dos híbridos 12, 25 e 27 visando a obtenção de novas cultivares de alfaces biofortificadas vermelhas e verdes, para os segmentos de alface crespa, americana, mini e romana. mundial saúde Lactuca L.

ABSTRACT The mechanized cutting of sugarcane requires improvements, as cutting tools can affect the longevity of sugarcane fields and increase production costs. Furthermore, these tools can increase the energy demand of machines in the field. This study evaluated the sugarcane harvester performance equipped with different basal cutting devices: impact cutting (blades) and continuous cutting (saws) in three commercial sugarcane production areas. The experimental design was completely randomized in a 3 × 2 factorial scheme with six repetitions. Effective fuel consumption and harvesting capacity were evaluated. The saws increased fuel consumption per area by 3.9 and 8.9% per Mg harvested. The crop’s yield characteristics determine harvesting systems’ energy demand. For yields above 90 Mg ha-1, energy demand has stabilized up to 120 Mg ha-1. The fuel demand for harvesting ranged between 1.0 and 1.2 L Mg-1 of harvested material. Regardless of the cutting system, each Mg requires 37.3 kJ of energy to be removed from the field. improvements costs Furthermore field devices blades (blades (saws areas repetitions 39 9 3. 89 8 8.9 crops crop s systems ha1, ha1 ha 1, 1 ha-1 12 ha1. 1. 10 0 Mg1 Mg- material system 373 37 37. 8. ha-

RESUMO O corte mecanizado da cana-de-açúcar necessita de aprimoramentos, visto que as ferramentas de corte podem afetar a longevidade dos canaviais e aumentar os custos de produção. Além disso, essas ferramentas podem aumentar a demanda energética das máquinas no campo. Este estudo avaliou o desempenho de colhedoras de cana-de-açúcar equipadas com distintos mecanismos de corte basal: corte por impacto (lâminas) e corte contínuo (serras) em três áreas comerciais de produção de cana-de-açúcar. O consumo efetivo de combustível e a capacidade efetiva de colheita das máquinas foram avaliados em cada tratamento. O delineamento experimental adotado foi inteiramente casualizado em esquema fatorial 3 × 2 com seis repetições. As serras aumentaram o consumo de combustível por área em 3,9 e 8,9% por Mg colhido. As características produtivas da cultura determinam a demanda energética dos sistemas de colheita. Para produtividades acima de 90 Mg ha-1, a demanda energética estabilizou-se até 120 Mg ha-1. A demanda de combustível para a colheita variou entre 1,0 e 1,2 L Mg-1 de material colhido. Os resultados mostram que independente do sistema de corte, cada Mg de cana colhida necessita em média de 37,3 kJ de energia para ser retirado do campo. canadeaçúcar açúcar aprimoramentos disso campo basal lâminas (lâminas (serras canadeaçúcar. açúcar. tratamento repetições 39 9 3, 89 8 8,9 colhido ha1, ha1 ha 1, 1 ha-1 estabilizouse estabilizou se 12 ha1. 1. 10 0 Mg1 Mg- 373 37 37, 8, ha-

ABSTRACT Beans are a vital component of the human diet, being able to supply a large part of the daily protein requirements of individuals, in addition to containing considerable amounts of iron, calcium, vitamins, carbohydrates, fiber, and lysine. Controlled germination is an accessible and effective technique that aims to improve the nutritional, functional, and sensory qualities of seeds intended for food consumption. This study aimed to characterize fresh and germinated beans of Phaseolus vulgaris (carioca, branco, preto, gordo varieties) and Vigna unguiculata (cowpea). The germination process was conducted in trays containing the sand substrate (350 g) in the environmental conditions of the laboratory. The fresh and germinated beans were evaluated for physicochemical variables in triplicate. The germination process increased moisture content, water activity, ash, pH, soluble alcohol acidity, proteins, ascorbic acid, phenols, tannins, flavonoids, anthocyanins, and carotenoids. On the other hand, there was a reduction in the content of lipids, starch, and total sugars in bean seeds. With the increase in bioactive compounds, it was found that the germination process is an excellent method for increasing the nutritional quality of beans. diet individuals iron calcium vitamins carbohydrates fiber lysine functional consumption carioca, carioca (carioca branco preto varieties cowpea. cowpea .

Brazil is home to a rich biodiversity of native edible fruits renowned for their health-promoting compounds and flavors. Among these, Eugenia uniflora L. (Brazilian pitanga) is particularly notable. The fruit varies in color from yellow to purple and is prized for its intense aroma and versatile taste profile. However, information about the compounds responsible for their nutritional and sensory potential is still limited. This study analyzed volatile compounds and metabolites in yellow, red and purple pitanga fruits (Eugenia uniflora) at various ripening stages, exploiting a metabolomics approach. Yellow pitanga had 30 volatile compounds, with esters (40%), terpenes (26.67%) and aldehydes (16.67%) constituting 83.34% of identified volatile compounds. Red pitanga featured 26 volatile compounds, primarily terpenes and esters (each 30.77%) and aldehydes (15.38%), making up 76.92%. Purple pitanga contained 39 volatile compounds, with terpenes and esters (each 35.90%) and aldehydes (17.95%), totaling 89.75% of identified volatile compounds. Across all pitanga types, 124 metabolites were identified, including saturated fatty acids (17.74%), terpenes (17.74%) and sugars (16.93%), constituting 52.41% of identified metabolites. Future studies should provide nutritional information, consumption methods and industrial applications for pitanga fruits, focusing on sensory analysis, health benefits, preservation and breeding to enhance bioactive compounds and flavor. healthpromoting promoting flavors these L Brazilian notable profile However limited stages approach 3 40%, 40 40% , (40%) 26.67% 2667 67 (26.67% 16.67% 1667 16 (16.67% 8334 83 34 83.34 2 each 30.77% 3077 77 15.38%, 1538 15.38% 15 38 (15.38%) 7692 76 92 76.92% 35.90% 3590 35 90 17.95%, 1795 17.95% 17 95 (17.95%) 8975 89 75 89.75 types 12 17.74%, 1774 17.74% 74 (17.74% 16.93%, 1693 16.93% 93 (16.93%) 5241 52 41 52.41 analysis benefits flavor 4 (40% 26.67 266 6 (26.67 16.67 166 1 (16.67 833 8 83.3 30.77 307 7 153 15.38 (15.38% 769 9 76.92 35.90 359 179 17.95 (17.95% 897 89.7 177 17.74 (17.74 169 16.93 (16.93% 524 5 52.4 (40 26.6 (26.6 16.6 (16.6 83. 30.7 15.3 (15.38 76.9 35.9 17.9 (17.95 89. 17.7 (17.7 16.9 (16.93 52.

ABSTRACT Objective: To evaluate the association between modifiable lifestyle behaviors and mental health indicators in Brazilian adolescents. Methods: This cross-sectional study used data from the 2019 National Survey of School Health including 152,860 students. The lifestyle behaviors and mental health indicators were obtained from a self-reported questionnaire. Logistic regression analyses were used to examine the association between lifestyle behaviors and mental health indicators. Results: Infrequent healthy eating (OR 1.22; 95%CI 1.14–1.31), being inactive (OR 1.82; 95%CI 1.65–2.01), smoking (OR 1.24; 95%CI 1.10–1.40), and irregular school attendance (OR 1.31; 95%CI 1.22–1.40) were associated with not having close friends. Additionally, not having close friends was also associated with unhealthy eating (OR 0.86; 95%CI 0.81–0.92) and alcohol consumption (OR 0.81; 95%CI 0.75–0.87). Infrequent healthy eating (OR 1.29; 95%CI 1.24–1.33), frequent unhealthy eating (OR 1.39; 95%CI 1.35–1.43), being inactive (OR 1.12; 95%CI 1.07–1.18), excessive screen time and sitting (OR 1.10; 95%CI 1.07–1.14 and OR 1.68; 95%CI 1.63–1.73, respectively), smoking (OR 1.26; 95%CI 1.19–1.34), alcohol (OR 1.33; 95%CI 1.28–1.37), drugs (OR 1.13; 95%CI 1.05–1.22), and irregular school attendance (OR 1.53; 95%CI 1.48–1.59) were associated with worse self-rated mental health. Conclusions: Various lifestyle behaviors are associated with different indicators of mental health.

Abstract Purpose: To analyze diabetes mellitus (DM) in a multifactorial manner with the consumption of sugar-sweetened beverages (SSB) and variables like nutritional status, sex, genetic predisposition, age and ethnicity; in order to determine the relationship between BGA and DM in the Mazahua Otomí (MO) community. Methodological design: This quantitative survey on social and nutritional variables was designed, validated and applied. A logistic model was developed to find the relationship of DM in relation to the variables: SSB consumption, sex, genetic predisposition, age, body mass index and ethnicity. Results: The Mazahua otomi community has a monthly family income below the extreme poverty line; they do not have disease control: 68% are obese or overweight and SSB consumption is medium to high in 90% of the population. In a multifactorial manner and according to the model, there is a probability of manifesting DM depending on the variables mentioned above; while, with the exception of nutritional status and age, the others are the most significant. In taste and preferences, 52% opt for the Coca-Cola SSB brand. Research limitations: The results found should be complemented in other case studies in communities with similar characteristics and a broader probabilistic population sample. Finding: In the MO community there is a relationship between BGA consumption and DM and there is no control of the disease. This work contributes to the design of public policies to prevent health damage because of excessive consumption of SSB and its relationship with DM; likewise, those policies that rescue and promote good nutritional practices of the communities of indigenous peoples.

Resumen Objetivo: Analizar en forma multifactorial la diabetes mellitus (DM) con el consumo de las bebidas gaseosas azucaradas (BGA) y de las variables estado nutricional, sexo, predisposición genética, edad y etnia, para determinar la relación de las BGA y la DM en la comunidad Mazahua Otomí (MO). Diseño Metodológico: El estudio fue cuantitativo. Se diseñó, validó y aplicó una encuesta estructurada sobre variables sociales y nutricionales. Se elaboró un modelo logístico para encontrar la relación de DM con las variables: consumo de BGA, sexo, predisposición genética, edad, índice de masa corporal y etnia. Resultados: En la comunidad MO que se investigó un padre de familia promedio tiene un ingreso mensual por debajo de la línea de pobreza extrema y no existe control de la enfermedad de estudio: 68% tiene obesidad o sobrepeso y el consumo de BGA es entre medio y alto en 90% de la población. En forma multifactorial, hay probabilidad de manifestar la DM en función de las variables antes señaladas; mientras que, a excepción de estado nutricional y la edad, las demás son las más significativas. En gustos y preferencias, 52% opta por la marca de BGA Coca-Cola. Limitaciones de la investigación: Los resultados encontrados deberán complementarse con estudios de caso en comunidades con características similares y una muestra poblacional probabilística más amplia. Hallazgos: En la comunidad MO existe una relación entre el consumo de BGA y la DM y no hay control de la enfermedad. Este trabajo aporta al diseño de políticas públicas de prevención del daño a la salud por el consumo excesivo de BGA y su relación con la DM. De igual manera aquellas políticas públicas que rescaten y fomenten las buenas prácticas nutritivas entre las comunidades de los pueblos originarios.

Resumo: Este artigo analisa o processo de integração em novos padrões de consumo de jovens assalariados rurais em um território da serra equatoriana, onde predominam os negócios agrícolas de flores e brócolis. O objetivo é mostrar as condições estruturais que permitem aos jovens assalariados adotarem novos habitus mais próximos do consumo de bens globais, um processo intimamente relacionado com a sua posição no campo social. Na primeira parte, analisamos a relação entre consumo e habitus nas zonas rurais a partir de diferentes perspectivas teóricas sociológicas. A segunda parte, baseada em um estudo de caso, trata das tendências de consumo entre a juventude rural. A terceira parte reflete sobre a importância de novos padrões de consumo entre os jovens assalariados através do acesso a dois tipos de mercadorias globais (motocicleta e celular) que se tornaram novos objetos simbólicos e de prestígio.

Abstract: This article analyzes the process of integration into new consumption patterns of young rural wage earners in a territory of the Ecuadorian highlands, where flower and broccoli agribusinesses predominate. We seek to show the structural conditions that allow young wage earners to adopt new habitus closer to the consumption of global goods, a process narrowly related to their position in the social field. In the first part, we analyze the relationship between consumption and habitus in rural areas from different sociological theoretical perspectives. In the second part, based on a case study, we address consumption trends among rural youth. The third part reflects on the importance of new consumption patterns among young wage earners through access to two types of global merchandise (motorcycle and cell phone) that have become new symbolic and prestige objects.
