RESUMEN Introducción: Paraguay asumió el reto de lograr cobertura universal mediante redes basadas en Atención Primaria de la Salud con Unidades de Salud de la Familia (USF) en el primer nivel de atención. Un desafío es la atención integral ante enfermedades no transmisibles, principal causa de mortalidad en el país. Objetivo: analizar la capacidad de las USF para la atención de personas con hipertensión arterial y diabetes en el sistema nacional de salud. El diseño fue no experimental, cuantitativo, transversal, descriptivo con componente analítico. Metodología: Incluyó a 761 USF de 12 regiones sanitarias agrupados en 4 ejes territoriales. Se adaptó el método de evaluación SARA de la OMS con 75 variables, aplicando un cuestionario a profesionales de salud entre noviembre y diciembre de 2022. Se calculó índices de disponibilidad y preparación así como un índice que los integra. La medida continua de estos índices se categorizó en 3 grupos: suficiente >0,75 a 1; intermedio 0,5 a 0,75 y bajo <0,5. Resultados: Solo en el 38 % de las USF el índice de disponibilidad fue suficiente, en el 31,5 % para el índice de preparación y en el 31,1 % para el índice integrador SARA DM/HTA. El desempeño se asoció de forma significativa con el eje territorial no así con el área ni con la cobertura a población indígena Discusión: las USF presentaron limitaciones para la atención de personas con diabetes e hipertensión en estas regiones del país.

ABSTRACT Introduction: Paraguay assumed the challenge of achieving universal coverage through networks based on Primary Health Care with Family Health Units (USF) at the first level of care. One challenge is comprehensive care for non-communicable diseases, the main cause of mortality in the country. Objective: to analyze the capacity of the USF to care for people with high blood pressure and diabetes in the national health system. The design was non-experimental, quantitative, cross-sectional, descriptive with an analytical component. Methods: It included 761 USF from 12 health regions grouped into 4 territorial axes. The WHO SARA evaluation method was adapted with 75 variables, applying a questionnaire to health professionals between November and December 2022. Availability and preparation indices were calculated as well as an index that integrates them. The continuous measurement of these indices was categorized into 3 groups: sufficient >0.75 to 1; intermediate 0.5 to 0.75 and low <0.5. Results: Only in 38.0% of the USF the availability index was sufficient, in 31.5% for the readiness index and in 31.1% for the SARA DM/HTA integrating index. The performance was significantly associated with the territorial axis, but not with the area or with the coverage of the indigenous population. Discussion: the USF presented limitations for the care of people with diabetes and hypertension in these regions of the country.

Abstract This article aims to present growth curves for height, weight, and BMI of 95,000 Brazilian youths aged 6 to 17 years, including the five regions of the country, the Amazon region, and indigenous populations, and compare them with the World Health Organization (WHO) growth references. The final sample consisted of 52,729 boys and 42,731 girls from the “Projeto Esporte Brasil” database. Body mass and height information were used to derive the curves. The generalized additive model for location, scale, and shape was employed. In this study, we present smoothed weight-for-age, height-for-age, and BMI-for-age curves for boys and girls. Differences were observed between the results of the Brazilian curves and the WHO growth references. The developed curves will be valuable for professionals in medicine, public health, nutrition, physical education, and other related fields, regarding the assessment of physical growth in Brazilian children and adolescents and monitoring the nutritional status of this population. Additionally, these curves will facilitate the identification of individuals or subgroups at risk of diseases and delayed growth, with a greater focus on specific country-related factors.

Resumo O objetivo do artigo é apresentar curvas de crescimento de altura, peso e IMC de 95.000 jovens brasileiros com idades entre 6 e 17 anos, incluindo as cinco regiões do país, a região da Amazônia e os povos indígenas, e comparar com as referências de crescimento da Organização Mundial da Saúde (OMS). A amostra final foi composta por 52.729 meninos e 42.731 meninas provenientes do banco de dados do “Projeto Esporte Brasil”. As informações de massa corporal e estatura foram utilizadas para derivar as curvas. O modelo aditivo generalizado para localização, escala e forma foi usado. neste estudo, apresentamos as curvas suavizadas de peso-idade, altura-idade e IMC-idade para meninos e meninas. Foram observadas diferenças entre os resultados das curvas brasileiras e as referências de crescimento da OMS. As curvas desenvolvidas serão úteis para profissionais da medicina, saúde pública, nutrição, educação física, entre outros, no que diz respeito a avaliação do crescimento físico de crianças e adolescentes brasileiros e para monitorar o estado nutricional desta população. Além disso, essas curvas permitirão a detecção de indivíduos ou subgrupos em risco de doenças e crescimento retardado, com um foco maior em fatores específicos do país.

Abstract The objective of this research is to estimate and decompose the wage gap between indigenous and non-indigenous workers by region in Mexico, to examine whether there are regional differences in the existing wage inequality that a priori affects the indigenous population and whether these differences can be attributed to the job profile of this group or by systematic labor discrimination against them. Using the data from the 2018 National Household Expenditure Revenue Survey (ENIGH-N) and the Oaxaca- Blinder decomposition, it was found that indigenous workers face a wage gap in all regions of the county. But, this gap is more pronounced in the center and south regions, where, on average, the associated component with labor discrimination has a percentage greater than 56. In contrast, in the north-central and northern regions of Mexico, the residual component is on average less than 33%, which suggests that the wage gap is explained by differences in productivity between groups.

Resumen El objetivo de esta investigación es estimar y descomponer la brecha salarial entre trabajadores indígenas y no indígenas por regiones en México, para examinar si existen diferencias regionales en la desigualdad salarial que a priori afecta a la población indígena y si estas, se atribuyen al perfil laboral de este grupo de trabajadores o a una discriminación laboral sistemática en su contra. Utilizando los datos de la Encuesta Nacional de Ingreso y Gasto de los Hogares de 2018 (ENIGH-N) y la descomposición de Oaxaca-Blinder (1973), se encontró que, en todas las regiones del país, los trabajadores indígenas enfrentan una brecha salarial. Pero, esta es más pronunciada en el centro y sur, en donde, en promedio, el componente asociado a la discriminación laboral tiene un peso mayor al 56%. En cambio, en el centro-norte y norte de México, el promedio del componente residual es menor 33%, lo que sugiere que la brecha salarial se explica por las diferencias grupales en la productividad.

Abstract In Nayarit, Mexico, there is an Integrated System of Tobacco Production (SIPT) which operates mainly with the participation of campesino families. However, for some preparatory work and to guarantee the harvest, local jornaleros and indigenous migrant families from the mountainous regions of Nayarit, Jalisco, Durango, and Zacatecas are hired, manly on a temporarily basis. They live for several months in precarious conditions in the houses and yards of the growers and on the agricultural plots. Since the Marco’s Convention and the General Law on Tobacco Control, the companies that control the SIPT have adopted new narratives and strategies for managing and sustaining their businesses, mainly emphasizing the so-called Corporate Social Responsibility (CSR). The objective of this article is to analyze the CSR actions of the tobacco companies from an approach of accumulation by dispossession, understanding CSR as a capitalist tool for the extraction of surplus value. With the support of a qualitative methodology, based on bibliographic and hemerographic review, direct observation, field diaries and interviews, also corporate actions comprised between 2018 and 2023 have also been documented. British American Tobacco and Tabacos del Pacífico Norte have “sponsored” the operation of the Florece centers and the Sustenta program in the tobacco fields of Nayarit, even though, in the tobacco reality of the tobacco industry the operation of such programs and their costs are assumed and absorbed by the growers, while the companies disseminate an image of sustainable business management.

Resumen En Nayarit, México, se configura un Sistema Integrado de Producción de Tabaco (SIPT) que opera principalmente con participación de familias campesinas aunque para algunas labores preparatorias y garantizar la cosecha de la hoja, se contrata temporalmente a jornaleros locales y familias indígenas migrantes originarias de las zonas serranas de Nayarit, Jalisco, Durango y Zacatecas, principalmente, quienes durante la zafra de cosecha viven por algunos meses en condiciones precarias en casas y patios de las viviendas de los productores y en las parcelas agrícolas. A partir del Convenio Marco y de la Ley General para el Control del Tabaco respectivamente, las empresas que controlan el SIPT adoptaron nuevas narrativas y estrategias para la gestión y continuidad de sus negocios, destacándose principalmente la llamada Responsabilidad Social Empresarial (RSE). El objetivo de este artículo es analizar las acciones de RSE de las compañías tabacaleras desde un enfoque de la Acumulación por Despojo, entendiendo la RSE como una herramienta capitalista para la extracción de plusvalía. Con apoyo de una metodología cualitativa, basada en la revisión bibliográfica y hemerográfica, observación directa, diarios de campo y entrevistas se han documentado acciones empresariales comprendidas entre 2018 a 2023. El análisis denota que la British American Tobacco y Tabacos del Pacífico Norte han “patrocinado” la operación de los centros Florece y del programa Sustenta en los campos de tabaco de Nayarit, aunque en la realidad tabacalera, la operación de dichos programas y sus costos son asumidos y absorbidos por los productores, mientras que las empresas difunden una imagen de gestión empresarial sustentable.

Abstract The division of our country into linguistic regions was defined in the second half of the 20th century and involved historical, geographic, and population aspects, in addition to linguistic features. This article intends to contribute to the dialectological studies on the Spanish spoken in Argentina, especially considering the data about the internal migrant population, migrant population from neighboring countries, and indigenous people who have settled in urban conglomerates, according to the 2010 census data. In Argentina, 91% of the population is urban and 66% is distributed in only 31 urban agglomerations. The coexistence of people from different origins is a favorable scenario for the exchange or contact between different languages. The acceleration of urban concentration during the last decades, concomitantly with a greater diversity of migrant and indigenous populations, allows a rethinking of the geography of dialect regions, focusing interest on the urban phenomenon. Demographic analysis shows that larger urban areas are highly diverse, including Greater Buenos Aires, the country’s largest agglomeration, and most Patagonian cities.

Resumen La división en regiones lingüísticas de nuestro país se define en la segunda mitad del siglo XX y contempla aspectos históricos, geográficos y poblacionales, además de los rasgos lingüísticos. Este artículo se propone realizar un aporte a los estudios dialectológicos sobre el español que se habla en la Argentina, considerando especialmente los datos en relación con la población migrante interna, migrante de países limítrofes e indígena que se ha radicado en conglomerados urbanos, de acuerdo con los datos censales de 2010. Estos datos muestran que el 91% de la población argentina es urbana y un 66% de la población total del país se distribuye en solo 31 aglomerados urbanos. La convivencia de personas de diversos orígenes resulta un escenario propicio para el intercambio o contacto entre diferentes lenguas. La aceleración del proceso de urbanización y concentración urbana durante las últimas décadas, concomitantemente con una mayor diversidad de las poblaciones migrantes e indígena, permite repensar la geografía de las regiones dialectales, focalizando el interés en el fenómeno urbano. El resultado del análisis demográfico muestra que son particularmente diversas las áreas urbanas más importantes, entre ellas, el Gran Buenos Aires, principal aglomerado del país, así como la mayoría de las ciudades patagónicas.

Street markets in Brazil are important spaces for the commercialization of fruits and vegetables (FV), which access by the urban population is considered one of the key aspects for the socalled “healthy cities”. This study adopts an ecological approach with geographic-spatial emphasis to describe accessibility to street markets in Porto Alegre, Brazil, by four different modes of transport (walking, bicycle, bus and car). The distribution of markets across the city is more balanced than other food establishments, although physical accessibility is highly uneven across modes of transport: the ability to reach a market on foot in 10 minutes or less is restricted to no more than 25 % of the population, while almost 90% can do it by driving a car. More importantly, the study found a direct and positive association between levels of accessibility to street markets and income: wealthier areas can reach fairs in less time using any mode of transport than poorer ones (p&lt;0.001). In addition, regions with a majority of white inhabitants have significantly better accessibility to the fairs on foot, by bicycle and by bus (p&lt;0.01) than regions with a majority of Black, Indigenous or yellow populations. Our study highlights the importance of addressing inequalities in access to healthy foods.

As feiras livres no Brasil são espaços importantes para a venda de frutas, verduras e legumes (FLV), considerados um dos aspectos-chave para “cidades saudáveis”. Este estudo adota uma abordagem ecológica com ênfase geográfico-espacial para descrever a acessibilidade às feiras livres em Porto Alegre, Brasil, por quatro modos de transporte (a pé, bicicleta, ônibus e carro). A distribuição das feiras pela cidade é mais equilibrada do que outros estabelecimentos de alimentos, embora a acessibilidade física seja altamente desigual entre os diferentes modos de transporte: a capacidade de alcançar uma feira a pé em 10 minutos ou menos é restrita a menos de 25% da população, enquanto quase 90% podem fazê-lo dirigindo um carro. Mais importante, o estudo encontrou uma associação direta e positiva entre os níveis de acessibilidade às feiras e a renda: as localidades mais ricas podem chegar às feiras em menos tempo usando qualquer modo de transporte do que as mais pobres (p&lt;0,001). Além disso, regiões com maioria de habitantes brancos têm acessibilidade significativamente melhor às feiras a pé, de bicicleta e de ônibus (p&lt;0,01) do que regiões com maioria de população negra, indígena ou amarela. Nosso estudo destaca a importância de abordar as desigualdades no acesso aos alimentos saudáveis.

Resumen Objetivo: Analizar la alimentación habitual de los afromexicanos en el contexto de dos procesos históricos y el ejercicio regional de producción/poder. Metodología: Entrevistas y observación participante en dos regiones con historia de producción hacienda/ejido; referencias socioeconómicas, dieta de recordatorio de 24 horas, lactancia y alimentación complementaria. Resultados: Las listas de alimentos reflejan disponibilidad y biodiversidad, pero no acceso y consumo habitual. Quedaron identificados intersticios, espacios con mayor margen de libertad para la manifestación y desarrollo de una cultura alimentaria campesina. Limitaciones: La dieta de 24 horas fue de un día y el consumo fuera del hogar no fue considerado. Conclusiones: La condición sociohistórica de producción determina buena parte del sistema alimentario, con base en alimentos y técnicas reproducidos por la población indígena. Hay diferencias alimentarias regionales, sin embargo, en buena medida corresponde a la alimentación de las poblaciones campesinas. Los alimentos aportan suficiente energía/vitaminas y esta proviene principalmente del maíz, frijol, arroz y las verduras de color verde, blanca y roja.

Abstract Objective: To analyze the habitual food of Afro-Mexicans in the context of two historical processes and the regional exercise of production/power. Methodology: Interviews and participant observation in two regions with a history of hacienda/ejido production; socioeconomic references, 24-hour recall diet, breastfeeding, and complementary feeding. Results: The food lists reflect availability and biodiversity, but not access and habitual consumption. Interstices, spaces with a greater margin of freedom were identified for the manifestation and development of a peasant food culture. Limitations: The 24-hour diet was for one day and consumption outside home was not considered. Conclusions: The sociohistorical condition of production/power determines a major part of the food system, based on foods and techniques reproduced by the indigenous population. There are regional dietary differences, however, to a large extent it corresponds to the diet of rural populations. The food provides enough energy/vitamins, and this comes mainly from corn, beans, rice and green, white and red vegetables.

ABSTRACT Traditional ecological knowledge of indigenous groups in the southeastern Colombian Amazon coincides in identifying the two main hydrological transition periods (wet-dry: August-November; dry-wet: March-April) as those with greater susceptibility to disease in humans. Here we analyze the association between indigenous knowledge about these two periods and the incidence of two vector-borne diseases: malaria and dengue. We researched seven “ecological calendars” from three regions in the Colombian Amazon, malaria and dengue cases reported from 2007 to 2019 by the Colombian National Institute of Health, and daily temperature and precipitation data from eight meteorological stations in the region from 1990-2019 (a climatological normal). Malaria and dengue follow a seasonal pattern: malaria has a peak from August to November, corresponding with the wet-dry transition (the “season of the worms” in the indigenous calendars), and dengue has a peak in March and April, coinciding with the dry-wet transition. Previous studies have shown a positive correlation between rainfall and dengue and a negative correlation between rainfall and malaria. However, as the indigenous ecological knowledge codified in the calendars suggests, disease prediction cannot be reduced to a linear correlation with a single environmental variable. Our data show that two major aspects of the indigenous calendars (the time of friaje as a critical marker of the year and the hydrological transition periods as periods of greater susceptibility to diseases) are supported by meteorological data and by the available information about the incidence of malaria and dengue.

RESUMEN Los conocimientos ecológicos tradicionales de grupos indígenas del sureste de la Amazonia colombiana coinciden en identificar dos principales periodos de transición hidrológica (seco-húmedo: agosto-noviembre; húmedo-seco: marzo-abril) como los de mayor susceptibilidad a enfermedades en humanos. Aquí analizamos la asociación entre el conocimiento indígena sobre estos dos periodos y la incidencia de dos enfermedades transmitidas por vectores: malaria y dengue. Investigamos siete calendarios ecológicos de tres regiones en la Amazonia colombiana, casos de dengue y malaria reportados de 2007 hasta 2019 por el Instituto Nacional de Salud de Colombia y datos diarios de temperatura y precipitación de ocho estaciones meteorológicas en la región, de 1990 a 2019 (una normal climatológica). Malaria y dengue siguen un patrón estacional, la malaria tiene un pico de agosto a noviembre, correspondiendo con la transición húmedo-seco (el “tiempo de gusano” según los calendarios indígenas), mientras que dengue tiene un pico de marzo a abril, coincidiendo con la transición seco-húmedo. Estudios previos mostraron una correlación positiva entre precipitación y dengue, y una correlación negativa entre precipitación y malaria. Sin embargo, como lo sugiere el conocimiento ecológico codificado en los calendarios indígenas, la predicción de enfermedades no puede reducirse a una correlación lineal con una sola variable medioambiental. Nuestros datos muestran que dos aspectos principales de los calendarios indígenas (el tiempo de friaje como un marcador crítico anual y los periodos de transición hidrológica como épocas de mayor susceptibilidad a enfermedades) están soportados por datos meteorológicos e información disponible acerca de la incidencia de malaria y dengue.

The coastal regions of Africa are endowed with indigenous wild fruit plants rich in nutritional and medicinal phytochemicals and micronutrients. South African wild fruit plants complement the diet and health needs of rural poor households by providing vital dietary nutrients and remedies for various health concerns, and alleviating food insecurity. Milk plum, Natal plum, wild custard apple, and wild medlar medicinal plants are found mainly in the coastal provinces of South Africa. Studies have established that these plants are good sources of vitamins, essential elements, and bioactive phytocompounds such as flavonoids, phenolic acids, and terpenoids, which demonstrate significant antioxidant, antimicrobial and anti-inflammatory activities. The plants studied possess anti-epileptic, antiplasmodial, and snake antivenom qualities. Here we highlight the views of different reports on ethnopharmacological relevance, phytochemistry, and bioactivity of the selected South African indigenous medicinal plants. We found a research gap in the phytochemical composition and phytopharmacological activity evaluation of Carissa macrocarpa and Englerophytum magalismontanum. SIGNIFICANCE: South African indigenous medicinal plants augment the dietary and other health needs of the rural populace. The phytochemistry and phytopharmacological activities of C. macrocarpa and E. magalismontanum have been only partially studied, hence the need for further studies to examine their worth and possible use in cosmetic product enrichment

RESUMO OBJETIVO Avaliar fatores sociodemográficos associados ao consumo de alimentos ultraprocessados e a evolução temporal do consumo no Brasil entre 2008 e 2018. MÉTODOS Foram utilizados dados do consumo alimentar de indivíduos com idade ≥ 10 anos das Pesquisas de Orçamentos Familiares (POF) 2008–2009 e 2017–2018. Os alimentos foram agrupados segundo a classificação Nova. Modelos de regressão linear brutos e ajustados foram utilizados para avaliar a associação entre características sociodemográficas e o consumo de ultraprocessados em 2017–2018 e a variação temporal de seu consumo entre 2008 e 2018. RESULTADOS Alimentos ultraprocessados representaram 19,7% das calorias em 2017–2018. A análise ajustada mostrou que seu consumo foi maior no sexo feminino ( versus masculino) e nas regiões Sul e Sudeste ( versus Norte), e menor em negros ( versus brancos) e na área rural ( versus urbana), além de diminuir com o aumento da idade e aumentar com escolaridade e renda. O consumo de ultraprocessados aumentou 1,02 pontos percentuais (pp) de 2008–2009 a 2017–2018, sendo este aumento mais expressivo em homens (+1,59 pp), negros (+2,04 pp), indígenas (+5,96 pp), na área rural (+2,43 pp), naqueles com até 4 anos de estudo (+1,18 pp), no quinto mais baixo de renda (+3,54 pp) e nas regiões Norte (+2,95 pp) e Nordeste (+3,11 pp). Por outro lado, seu consumo se reduziu na maior faixa de escolaridade (-3,30 pp) e no quinto mais alto de renda (-1,65 pp). CONCLUSÕES Os segmentos socioeconômicos e demográficos que tiveram menor consumo relativo de ultraprocessados em 2017–2018 são justamente os que apresentaram um aumento mais expressivo na análise temporal, apontando para uma tendência de padronização nacional em um patamar de consumo mais alto.

ABSTRACT OBJECTIVE To evaluate sociodemographic factors associated with the consumption of ultra-processed foods and the temporal evolution of their consumption in Brazil between 2008 and 2018. METHODS The study used food consumption data of individuals aged ≥ 10 years from 2008–2009 and 2017–2018 Pesquisas de Orçamentos Familiares (POF - Household Budget Surveys), grouping the foods according to the Nova classification. We used crude and adjusted linear regression models to assess the association between sociodemographic characteristics and consumption of ultra-processed foods in 2017–2018 and the temporal variation in their consumption between 2008 and 2018. RESULTS Ultra-processed foods accounted for 19.7% of calories in 2017–2018. The adjusted analysis showed that their consumption was higher in women (versus men) and the South and Southeast regions (versus North) and lower in blacks (versus whites) and rural areas (versus urban), in addition to decreasing with the increased age and increasing with higher education and income. Consumption of ultra-processed foods increased by 1.02 percentage points (pp) from 2008–2009 to 2017–2018. This increase was significantly higher among men (+1.59 pp), black people (+2.04 pp), indigenous (+5.96 pp), in the rural area (+2.43 pp), those with up to 4 years of schooling (+1.18 pp), in the lowest income quintile (+3.54 pp), and the North (+2.95 pp) and Northeast (+3.11 pp) regions. On the other hand, individuals in the highest level of schooling (-3.30 pp) and the highest income quintile (-1.65 pp) reduced their consumption. CONCLUSIONS The socioeconomic and demographic segments with the lowest relative consumption of ultra-processed foods in 2017–2018 are precisely those that showed the most significant increase in the temporal analysis, pointing to a trend towards national standardization at a higher level of consumption.

Resumo: O objetivo deste estudo foi determinar a prevalência de fatores de risco cardiovascular entre diferentes grupos sociodemográficos de adolescentes de comunidades indígenas em Chiapas, México. Foi realizado um estudo transversal de prevalência em comunidades urbanas e rurais das regiões de Tzotzil-Tzeltal e Selva de Chiapas. Foi estudada uma amostra de 253 adolescentes, sendo 48% meninas e 52% meninos. Foi realizada uma análise descritiva das variáveis quantitativas por meio de medidas de tendência central e dispersão. Foram estimadas as prevalências de fatores de risco cardiovascular, estratificadas por sexo, área geográfica, escolaridade e etnia das mães. A prevalência dos fatores de risco cardiovascular foi analisada em relação às características sociodemográficas da população estudada. O HDL-c baixo (51%) foi o fator de risco cardiovascular predominante. Prevalências mais elevadas de obesidade abdominal, hipertrigliceridemia e colesterol total limítrofe foram mais observadas em meninas do que em meninos. A pressão arterial diastólica elevada prevaleceu nos meninos. Adolescentes da área urbana apresentaram prevalências de sobrepeso/obesidade e resistência à insulina maiores do que os da área rural. A prevalência de sobrepeso/obesidade e obesidade abdominal foi maior nos adolescentes cujas mães possuíam escolaridade ≥ 7 anos do que naqueles indivíduos cujas mães tinham baixa escolaridade. As diferenças de etnia das mães também foram observadas na prevalência de resistência à insulina. Dentre as principais conclusões, foram encontradas, neste estudo, desigualdades sociodemográficas e geográficas entre fatores de risco cardiovascular. Promover estilos de vida saudáveis entre a população jovem é o ideal para prevenir doenças cardiovasculares na vida adulta.

Abstract: This study was aimed to determine the prevalence of cardiovascular risk factors among different sociodemographic groups of adolescents from indigenous communities in Chiapas, Mexico. A cross-sectional prevalence study was performed in urban and rural communities in the Tzotzil-Tzeltal and Selva regions of Chiapas. A sample of 253 adolescents was studied, of whom 48% were girls and 52% were boys. A descriptive analysis of quantitative variables was performed using measures of central tendency and dispersion. The prevalence of cardiovascular risk factors stratified by sex, geographical area, years of schooling, and ethnicity of the mothers was estimated. The prevalence of cardiovascular risk factors was analyzed in relation to the sociodemographic characteristics of the study population. Low HDL-c (51%) was the predominant cardiovascular risk factor. Girls had a higher prevalence of abdominal obesity, hypertriglyceridemia, and borderline total cholesterol than boys. High diastolic blood pressure was more prevalent in boys. Adolescents from urban areas had a higher prevalence of overweight/obesity and insulin resistance than adolescents from rural areas. The prevalence of overweight/obesity and abdominal obesity was higher in adolescents whose mothers had ≥ 7 years of schooling compared with adolescents with less educated mothers. Differences by maternal ethnicity also influenced the prevalence of insulin resistance. Among the main findings, this study associated sociodemographic and geographical inequalities with cardiovascular risk factors. Promoting a healthy lifestyle for this young population is absolutely necessary to prevent cardiovascular diseases in adulthood.

Resumen: El objetivo de este estudio fue estimar la prevalencia de los factores de riesgo cardiovascular entre diferentes grupos sociodemográficos de adolescentes de comunidades indígenas de Chiapas, México. Se realizó un estudio transversal de prevalencia en comunidades urbanas y rurales de las regiones Tzotzil-Tzeltal y Selva, en Chiapas. Participó una muestra de 253 adolescentes, en la cual el 48% eran niñas y el 52% niños. Se realizó un análisis descriptivo de las variables cuantitativas utilizando medidas de tendencia central y dispersión. Se estimó la prevalencia de los factores de riesgo cardiovascular, estratificados por sexo, área geográfica, nivel de estudios y etnia de las madres. Se analizó la prevalencia de los factores de riesgo cardiovascular con relación a las características sociodemográficas de la población estudiada. El HDL-c bajo (51%) fue el factor de riesgo cardiovascular predominante. Se observó una mayor prevalencia de obesidad abdominal, hipertrigliceridemia y colesterol total en las niñas que en los niños. La alta presión arterial diastólica prevaleció en los niños. Los adolescentes del área urbana tuvieron una mayor prevalencia de sobrepeso/obesidad y resistencia a la insulina que los del área rural. La prevalencia de sobrepeso/obesidad y obesidad abdominal fue mayor en los adolescentes cuyas madres tenían nivel de estudios ≥ 7 años que aquellos cuyas madres tenían bajo nivel de estudios. Las diferencias en la etnicidad materna también influyeron en la prevalencia de resistencia a la insulina. Entre las principales conclusiones de este estudio, se destacan las desigualdades sociodemográficas y geográficas entre los factores de riesgo cardiovascular. La promoción de un estilo de vida saludable entre la población joven es lo indicado para prevenir las enfermedades cardiovasculares en la edad adulta.

Abstract Carnivals are opportunities to understand a wide range of dynamics, processes, and historical periods. Analyzing them implies more than a simple description or an isolated glance. In the emerging field of carnival studies, it is necessary to identify, categorize, and theorize about the intra- and interregional differences and similarities in order to understand the possible macroprocesses and the historical, territorial, social, cultural, ethnic, and political factors that have shaped the diverse nature of these celebrations. Inversely, it is useful to examine how certain regions manifest particular types of carnivals. A review of contrasting literature using the theoretical framework of regionalization illustrates the need for a regional focus in the analysis of the human-cultural expression of carnival in Mexico and their particular expressions in the regions or states of the country, encouraging the creation of a truly glocal-regional understanding and the strengthening of this field of studies.

Resumen Los carnavales son oportunidades para comprender dinámicas, procesos y periodos históricos, y analizarlos implica más que descripciones simples o miradas aisladas. En el campo emergente de los estudios sobre el carnaval hace falta identificar, categorizar y teorizar las diferencias y similitudes intra e interregionales para comprender los posibles macroprocesos y los factores históricos, territoriales, sociales, culturales, étnicos y políticos que formaron la diversidad de estas celebraciones; de manera inversa, es útil indagar acerca de cómo en algunas regiones se manifiestan ciertos tipos de carnaval. Mediante una revisión y contraste bibliográfico desde un enfoque de regionalidad, se analiza y categoriza la expresión humano-cultural del carnaval en México, buscando catalogar su presencia en diferentes regiones y estados para ilustrar qué regionalidad(es) caracteriza(n) el carnaval en el país y sostener que el análisis regional facilita una comprensión glocal profunda que puede reforzar el campo de los estudios sobre el tema.

ABSTRACT Objective: To describe the space-time evolution of TB incidence rates (TI) in indigenous and non-indigenous people, according to the Federative Units (UF) of Brazil, from 2011 to 2022. Methods: Ecological, temporal, and spatial study on new tuberculosis cases in Brazil among indigenous and non-indigenous populations. Data from the Notifiable Diseases Information System (Sinan) were collected from 2011 to 2022 and stratified by Federal Unit, explored and statistically analyzed using R software version 4.2.3. Results: The mean TI among indigenous populations in Brazil was 71.7 new cases per 100,000 inhabitants, while for non-indigenous populations it was 28.6/100,000 inhabitants. The regions of the country that presented the highest (mean) incidence among indigenous populations were: Central-West (102.8/100,000 inhabitants), Southeast (99.6/100,000 inhabitants), and North (79.9/100,000 inhabitants). For non-indigenous populations the highest incidence was in the North region (36.5/100,000 inhabitants), followed by the Southeast (31.3/100,000), and the Northeast (27,4/100,000 inhabitants). The analysis showed that the highest incidence of TB cases among indigenous populations occurred in the states of: SP, RO, RJ, MS, MT e PA. Conclusion: High incidence of the disease compared to the non-indigenous population show the need for a specific approach to address the health needs of these populations. Regional disparities in incidence indicate the need to address socioeconomic and infrastructure issues that affect the health of indigenous populations.

RESUMO Objetivo: Descrever a evolução espaço-temporal das taxas de incidência (TIs) de tuberculose (TB) em indígenas e não indígenas, segundo as unidades federativas do Brasil, no período de 2011 a 2022. Métodos: Estudo ecológico, temporal e espacial sobre os casos novos de tuberculose no Brasil em indígenas e não indígenas. Dados provenientes do Sistema de Informação de Agravos de Notificação (SINAN) foram coletados de 2011 a 2022 e estratificados por UF, analisados exploratória e estatisticamente por meio do software R 4.2.3. Resultados: A TI média entre indígenas no Brasil foi 71,7 casos novos para cada 100 mil habitantes, enquanto para não indígenas foi de 28,6/100 mil habitantes. As regiões do país que apresentaram as maiores incidências (médias) para indígenas foram: Centro-Oeste (102,8/100 mil hab.), Sudeste (99,6/100 mil hab.) e Norte (79,9/100 mil hab.), e para não indígenas foram: Norte (36,5/100 mil hab.), Sudeste (31,3/100 mil hab.) e Nordeste (27,4/100 mil hab.). A análise mostrou que a maior incidência de casos de TB nas populações indígenas ocorreu nos estados de São Paulo, Rondônia, Rio de Janeiro, Mato Grosso do Sul, Mato Grosso e Pará. Conclusão: Altas incidências da doença em comparação com a população não indígena mostraram a necessidade de abordagem específica para atender às necessidades de saúde dessas populações.

Abstract Acmella bellidioides (Asteraceae), commonly known as "arnica-do-campo", is a South American native medicinal plant mainly found in Brazil, Argentina, Uruguay and Paraguay. The indigenous people in these regions use the flowers of this plant to treat diseases of the digestive, musculoskeletal and sensory systems. Many Acmella species are morphologically similar, and there are a few anatomical studies available in the literature that can be used to identify and distinguish them. Several other members of Asteraceae, such as Calea uniflora, Chaptalia nutans, Porophyllum ruderale, Pseudobrickellia brasiliensis and Solidago chilensis, are also called "arnica-do-campo" or "arnica". Applying the same common name to several other species makes it difficult to identify the plant correctly and allows it to be more easily adulterated. The present study characterizes A. bellidioides using microscopy and microchemical techniques to provide pharmacobotanical data to support the authentication of the species. The notable anatomical markers identified in A. bellidioides are hypostomatic leaves, anomocytic stomata, peltate glandular trichomes on the leaf abaxial surface, midrib vascular system with three collateral bundles in an open arch, and the presence of prismatic crystals in the leaves and stems. These characteristics can help species identification and differentiation of A. bellidioides from other Acmella species and Asteraceae species known as arnica-do-campo.

ABSTRACT OBJECTIVE To evaluate sociodemographic factors associated with the consumption of ultra-processed foods and the temporal evolution of their consumption in Brazil between 2008 and 2018. METHODS The study used food consumption data of individuals aged ≥ 10 years from 2008–2009 and 2017–2018 Pesquisas de Orçamentos Familiares (POF - Household Budget Surveys), grouping the foods according to the Nova classification. We used crude and adjusted linear regression models to assess the association between sociodemographic characteristics and consumption of ultra-processed foods in 2017–2018 and the temporal variation in their consumption between 2008 and 2018. RESULTS Ultra-processed foods accounted for 19.7% of calories in 2017–2018. The adjusted analysis showed that their consumption was higher in women (versus men) and the South and Southeast regions (versus North) and lower in blacks (versus whites) and rural areas (versus urban), in addition to decreasing with the increased age and increasing with higher education and income. Consumption of ultra-processed foods increased by 1.02 percentage points (pp) from 2008–2009 to 2017–2018. This increase was significantly higher among men (+1.59 pp), black people (+2.04 pp), indigenous (+5.96 pp), in the rural area (+2.43 pp), those with up to 4 years of schooling (+1.18 pp), in the lowest income quintile (+3.54 pp), and the North (+2.95 pp) and Northeast (+3.11 pp) regions. On the other hand, individuals in the highest level of schooling (-3.30 pp) and the highest income quintile (-1.65 pp) reduced their consumption. CONCLUSIONS The socioeconomic and demographic segments with the lowest relative consumption of ultra-processed foods in 2017–2018 are precisely those that showed the most significant increase in the temporal analysis, pointing to a trend towards national standardization at a higher level of consumption.

RESUMO OBJETIVO Avaliar fatores sociodemográficos associados ao consumo de alimentos ultraprocessados e a evolução temporal do consumo no Brasil entre 2008 e 2018. MÉTODOS Foram utilizados dados do consumo alimentar de indivíduos com idade ≥ 10 anos das Pesquisas de Orçamentos Familiares (POF) 2008–2009 e 2017–2018. Os alimentos foram agrupados segundo a classificação Nova. Modelos de regressão linear brutos e ajustados foram utilizados para avaliar a associação entre características sociodemográficas e o consumo de ultraprocessados em 2017–2018 e a variação temporal de seu consumo entre 2008 e 2018. RESULTADOS Alimentos ultraprocessados representaram 19,7% das calorias em 2017–2018. A análise ajustada mostrou que seu consumo foi maior no sexo feminino ( versus masculino) e nas regiões Sul e Sudeste ( versus Norte), e menor em negros ( versus brancos) e na área rural ( versus urbana), além de diminuir com o aumento da idade e aumentar com escolaridade e renda. O consumo de ultraprocessados aumentou 1,02 pontos percentuais (pp) de 2008–2009 a 2017–2018, sendo este aumento mais expressivo em homens (+1,59 pp), negros (+2,04 pp), indígenas (+5,96 pp), na área rural (+2,43 pp), naqueles com até 4 anos de estudo (+1,18 pp), no quinto mais baixo de renda (+3,54 pp) e nas regiões Norte (+2,95 pp) e Nordeste (+3,11 pp). Por outro lado, seu consumo se reduziu na maior faixa de escolaridade (-3,30 pp) e no quinto mais alto de renda (-1,65 pp). CONCLUSÕES Os segmentos socioeconômicos e demográficos que tiveram menor consumo relativo de ultraprocessados em 2017–2018 são justamente os que apresentaram um aumento mais expressivo na análise temporal, apontando para uma tendência de padronização nacional em um patamar de consumo mais alto.
