RESUMO

Introduction. Colombia is home to 2 million indigenous people who live in conditions of poverty and with health deficiencies, making them vulnerable to contracting hepatitis B (HBV). Amazonas has a high virus prevalence, and there are barriers to accessing vaccination; thus, part of the population is susceptible to infection. Objective. To identify factors associated with HBV in Colombian indigenous people. Materials and Methods. A case-control study of people over 18 years from four departments of Colombia. Cases were identified through the national hepatitis B notification registry (2015-2022). Controls were selected and matched to cases (2:1) by age, sex, ethnicity, and department. Sociodemographic characteristics, factors associated with contact with body fluids, cultural practices, and vaccination history were identified by means of a survey. The ethics committee of the Universidad de Antioquia approved the project. Results. Seventy five cases and 150 controls from 13 ethnic groups were surveyed. Amazonas contributed 49% of participants, 83% were women, and the median age of cases was 30 years (IQ range: 27-37). The associated factors were a family history of hepatitis B [adjusted OR: 2.61 (95% CI: 1.09-6.27)] and, in women, the number of pregnancies [adjusted OR: 1.61 (95% CI 1.02- 2.54)]. The vaccination history showed a protective effect, but the association was not significant. Conclusion. Aspects associated with family life and unprotected sexual relations seem to be responsible for the potential transmission of the virus. It was not possible to identify associated cultural practices. Innovative and differential strategies are required for indigenous people to achieve a reduction of HBV.

Introducción. Colombia alberga dos millones de indígenas, que viven en condiciones de pobreza y tienen deficiencias en salud, por lo cual están expuestos a contraer infecciones virales como la hepatitis B. El departamento del Amazonas presenta una gran prevalencia del virus y barreras para acceder a la vacunación; por esto, parte de la población es propensa a la infección. Objetivo. Identificar factores asociados con la infección por el virus de la hepatitis B en indígenas colombianos. Materiales y métodos. Se llevó a cabo un estudio de casos y controles en mayores de 18 años de cuatro departamentos del país. Los casos se identificaron mediante el registro nacional de notificación de hepatitis B (2015-2022). Los controles seleccionados de manera concurrente fueron pareados con los casos por edad, sexo, etnia y departamento. En una encuesta se consignaron las características sociodemográficas, los factores asociados con el contacto con sangre y fluidos, las prácticas socioculturales y los antecedentes de vacunación. El proyecto fue aprobado por Comité de Ética de la Universidad de Antioquia. Resultados. Participaron 75 casos y 150 controles de 13 grupos étnicos. El departamento del Amazonas aportó el 49 % de los participantes (83 % mujeres) con una mediana de edad de 30 años (RIC = 27-37). Los factores asociados con una mayor probabilidad de contraer la infección fueron el antecedente de algún familiar infectado con el virus de la hepatitis B (OR ajustado = 2,61) (IC95%: 1,09-6,27) y número de embarazos en mujeres, (OR ajustado = 1,61) (IC95%: 1,02-2,54). La vacunación mostró un efecto protector sin asociación significativa. Conclusión. Los aspectos asociados con la convivencia familiar y el número de embarazos contribuyen a una potencial transmisión vertical y horizontal del virus. No se identificaron prácticas culturales asociadas. Se requieren estrategias novedosas y diferenciales para reducir la transmisión del virus de la hepatitis B en poblaciones indígenas.

RESUMO

Background and Objectives: The primary objective of this study was to assess the adherence of Ngäbe-Buglé women to WHO-recommended prenatal practices. The secondary objective was to compare adherence levels between women who received prenatal education from official medical providers and those educated through traditional or community-based sources within Ngäbe-Buglé communities. Materials and Methods: An eight-question survey was verbally administered to 137 Ngäbe-Buglé women at clinics set up by the non-profit NGO Floating Doctors in eight communities. A two-sided Fisher's Exact test with a p = 0.05 was used to compare the results of mothers who received prenatal education from evidence-based sources to other groups. Results: Out of the 137 surveyed women, 65 reported taking prenatal vitamins, 21 had prenatal check-ups, 136 avoided alcohol, 31 increased caloric intake, and 102 maintained their activity levels. Significant differences were observed in prenatal vitamin adherence between those educated by official sources versus unofficial sources (p = 0.0029) and official sources compared to those with no prenatal education (p < 0.0001). The difference was also significant for education from an unofficial source versus no education (p = 0.0056). However, no significant differences were found in other prenatal practices based on education sources. Conclusions: Our findings highlight deficiencies in both prenatal education and adherence to recommended practices among Ngäbe-Buglé women. Prenatal education significantly improved adherence to taking prenatal vitamins, suggesting its effectiveness as an intervention. Future interventions should prioritize culturally competent prenatal education and address barriers to accessing prenatal healthcare in Ngäbe-Buglé communities.

RESUMO

Diabetic foot (DF) is a leading cause of nontraumatic lower-extremity amputations, premature death, and a sign of social inequality in diabetes treatment. In Mexico, the incidence of DF is on the rise yet little is known about its impact among indigenous people, a disadvantaged group. Based on ethnographic research conducted in Oaxaca and analysis of institutional health-data, in this article we show the health care delays that rural indigenous people face when dealing with DF. Indigenous people's uncertainty regarding their right to health and the structural barriers to medical care favor DF complications, a phenomenon that should be read as social suffering. Since health data concerning indigenous health care service users is patchy and imprecise, indigenous people's social suffering is invisibilized. This omission or partiality in the official records limits public health decision-making and undermines the human rights of the population.

RESUMO

Introducción: la información en cáncer en poblaciones indígenas colombianas es escasa; de ahí que el objetivo de este estudio sea conocer las perspectivas comunitarias y de los prestadores de servicios de salud acerca del cáncer de cuello uterino (CaCU) en mujeres indígenas del Amazonas colombiano. Materiales y métodos: estudio cualitativo, derivado de una investigación de métodos mixtos de triangula-ción convergente. Se realizaron 40 entrevistas semiestructuradas que incluían profesionales de la salud y actores clave comunitarios representados en curacas, médicos tradicionales o chamanes, parteras, pro-motores de salud, auxiliares de salud pública, líderes y lideresas, abuelos, abuelas y mujeres indígenas en general. Para el análisis se utilizó la técnica de análisis de contenido. Resultados: emergieron cuatro categorías:1) concepciones y factores de riesgo alrededor del cáncer en general y el CaCU, 2) prácticas de cuidado y de atención occidentales y ancestrales para el CaCU, 3) dificultades socioculturales y del sistema de salud para la prevención y atención del CaCU y 4) recomendaciones para el fortalecimiento de la de prevención del CaCU. Conclusión: los participantes reconocen la citología cervicouterina como una forma de prevenir el cáncer y aunque los participantes mencionaron algunos aspectos culturales y personales que podrían constituirse en una barrera para la prevención y control del CaCU, se hizo hinca-pié en los problemas estructurales del sistema de salud, la falta de integración cultural y las dificultades de acceso al tamizaje, diagnóstico y tratamiento.

Introduction: Information on cancer in Colombian indigenous populations is scarce, the objective of this study was to know the community and health care providers' perspectives on cervical cancer (CaCU) in indigenous women of the Colombian Amazon. Materials and methods: Qualitative study, derived from a mixed methods research of convergent triangulation, 40 semi-structured interviews were conducted, including health professionals and key community actors represented by curacas, traditional doctors or shamans, midwives, health promoters, public health assistants, leaders, grandfathers, grandmothers, and indigenous women in general. The content analysis technique was used for the analysis. Results:Four categories emerged: (a) conceptions and risk factors surrounding cancer in general and CaCU; (b) western and ancestral care and attention practices for CaCU; (c) sociocultural and health system diffi-culties for the prevention and attention of CaCU, and (d) recommendations for strengthening CaCU pre-vention. Conclusion: Participants recognize cervical cytology as a way to prevent cancer and although participants mentioned some cultural and personal aspects that could constitute a barrier to cervical cancer prevention and control, the greatest emphasis was given to structural problems of the health system, lack of cultural integration and difficulties of access to screening, diagnosis and treatment.

RESUMO

OBJECTIVE: This study examines maternal mortality among Brazilian indigenous women from 2015 to 2021, contrasting their causes of death with non-indigenous women. METHODS: An observational study utilizing Ministry of Health data analyzed maternal deaths' characteristics, comparing indigenous and non-indigenous groups based on death certificates and live-birth records. Variables included age, region, location, time, and cause of death. Maternal mortality ratios (MMR) were calculated with linear regression and outliers identified with Grubbs test. Prevalence ratios compared MMR and causes of death. RESULTS: Between 2015 to 2021, Brazil recorded 13 023 maternal deaths. Among these, with 205 among indigenous women (1.60% of total). Indigenous women had higher MMR (115.14/100 000), than non- indigenous women (66.92/100 000), consistently across years. Hemorrhagic causes notably contributed to the indigenous women's elevated MMR. CONCLUSION: Indigenous Brazilian women face elevated maternal mortality rates across all causes, primarily due to hemorrhage, contrasting wih national trends.

RESUMO

Widespread contamination of the Amazon basin with mercury has been reported to occur since at least the mid-80s due to heavy gold mining activity. Although initial studies have indicated that this may lead to deleterious neurological consequences to the indigenous populations living in the region, further research is needed to better characterize the neurological burden of such long-term exposure. With this aim, a cross-sectional exploratory study has been conducted with the Yanomami indigenous population residing in a northern Amazon region. All participants underwent a structured interview; detailed neurological examination, including assessment for cognitive, motor, coordination, and sensory functions; and laboratorial testing for serum hemoglobin, blood glucose, and methylmercury levels in hair samples. This study enrolled 154 individuals of 30.9 ± 16.8 years of age, of which 56.1% were female. Mean methylmercury levels in hair were 3.9 ± 1.7 µg/g. Methylmercury levels in hair > 6.0 µg/g were found in 10.3%. Among participants with hair methylmercury levels ≥ 6.0 µg/g, the prevalences of peripheral neuropathy and reduced cognitive performance were, respectively, 78.8% (95%CI 15-177%, p = 0.010) and 95.9% (95%CI 16-230.8%, p = 0.012) higher than those of individuals with lower levels. These results suggest that chronic mercury exposure may lead to significant and potentially irreversible neurotoxicity to Yanomami population living in the northern Amazon basin.

RESUMO

This opinion piece, written by ethnobiologists from different parts of the world, emphasizes the importance of ethnobiology research in advancing contemporary biology, natural resource management, biodiversity conservation, sustainable development, and, especially, contributing to the ecological transition and more just and inclusive world. To achieve these goals, it is essential to develop research and collaborate with social groups that live in close relationship with nature in research activities, such as Indigenous Peoples and Local Communities (IPLC), as well as Afro-descendants and other Marginalized, Minority or Minoritized Communities (AMMC). Ethnobiology can identify and provide locally appropriate solutions to local problems, enabling sustainable resource management at the landscape level. The text explores important aspects that need to be considered to guide the future of ethnobiology in the next 20 years, aiming to integrate and amplify previous discussions held in the discipline and identify points that demand ongoing attention. This paper highlights reflections from diverse researchers, emphasizing how ethnobiology can embrace different perspectives and employ rigorous analysis of complex phenomena toward effective policies and practices. This approach holds the potential to address the challenges the planet is currently facing in the coming decades.

RESUMO

This pilot study aimed to investigate genetic factors that may have contributed to the milder clinical outcomes of COVID-19 in Brazilian indigenous populations. 263 Indigenous from the Araweté, Kararaô, Parakanã, Xikrin do Bacajá, Kayapó and Munduruku peoples were analyzed, 55.2% women, ages ranging from 10 to 95 years (average 49.5 ± 20.7). Variants in genes involved in the entry of SARS-CoV-2 into the host cell (ACE1 rs1799752 I/D, ACE2 rs2285666 C/T, ACE2 rs73635825 A/G and TMPRSS2 rs123297605 C/T), were genotyped in indigenous peoples from the Brazilian Amazon, treated during the SARS-CoV-2 pandemic between 2020 and 2021. The distribution of genotypes did not show any association with the presence or absence of IgG antibodies. Additionally, the influence of genetic variations on the severity of the disease was not examined extensively because a significant number of indigenous individuals experienced the disease with either mild symptoms or no symptoms. It is worth noting that the frequencies of risk alleles were found to be lower in Indigenous populations compared to both continental populations and Brazilians. Indigenous Brazilian Amazon people exhibited an ethnic-specific genetic profile that may be associated with a milder disease, which could explain the unexpected response they demonstrated to COVID-19, being less impacted than Brazilians.
