RESUMO

BACKGROUND: Available data show that the epidemiological profile of most indigenous Brazilian populations is characterized by the coexistence of long-standing health problems (high prevalence of infectious and parasitic diseases, malnutrition, and deficiency diseases, such as anemia in children and women of reproductive age), associated with new health problems, especially those related to obesity (hypertension, type 2 diabetes mellitus and dyslipidemia). Based on this scenario, this study analyzed the nutritional profile of the adult population of seven indigenous peoples from the Brazilian Amazon in the years 2007 and 2021. METHODS: A total of 598 adults individuals were analyzed in 2007 (319 women and 279 men) and 924 in 2021 (483 women and 441 men), from seven indigenous peoples located in the state of Pará, who were assisted during health actions carried out in 2007 and in 2021. Body mass index classification used the World Health Organization criteria for adults: low weight, < 18.5 kg/m2; normal weight, ≥ 18.5 and < 25 kg/m2); overweight, ≥ 25 and < 30 kg/m2, and obesity, ≥ 30 kg/m2. A waist circumference (WC) < 90 cm in men and < 80 cm in women was considered normal. RESULTS: The data revealed heterogeneous anthropometric profiles, with a low prevalence of nutritional changes in the Araweté, Arara and Parakanã peoples, and high proportions of excess weight and abdominal obesity in the Kararaô, Xikrin do Bacajá, Asurini do Xingu and Gavião peoples, similar to or even higher than the national averages. CONCLUSION: Different stages of nutritional transition were identified in the indigenous peoples analyzed, despite apparently having been subjected to the same environmental pressures that shaped their nutritional profile in recent decades, which may indicate different genetic susceptibilities to nutritional changes. The evidence shown in this study strongly suggests the need to investigate in greater depth the genetic and environmental factors associated with the nutritional profile of Brazilian indigenous peoples, with assessment of diet, physical activity and sociodemographic and socioeconomic variables that enable the development of appropriate prevention and monitoring measures.

RESUMO

BACKGROUND: Malnutrition is a global problem that affects schoolchildren and can increase the risk of diseases in adulthood. Adult members of the Yaqui Indigenous group have been shown to have serious health problems, and Yaqui schoolchildren could therefore find themselves in a similar situation. OBJECTIVE: To evaluate the nutritional status, lipid profile and associated factors in a sample of Yaqui schoolchildren. MATERIAL AND METHODS: A total of 109 Yaqui schoolchildren who lived in their localities of origin were recruited. Anthropometric measurements were carried out, a venous blood sample was extracted in fasting conditions, and several questionnaires were applied. RESULTS: The prevalence of overweight/obesity was 38.5%, with no cases of chronic malnutrition being recorded; 38.6% of the children had dyslipidemia. Fiber consumption was a protective factor against overweight/obesity, while fat intake was a risk factor. The physical activity score was found to be a protective factor against dyslipidemia, and the risk factors were BMI-for-age Z-scores, waist circumference, family history of dyslipidemia, educational level, and permanent employment. CONCLUSIONS: Yaqui schoolchildren equally suffer from a high proportion of overweight/obesity and dyslipidemia. The associated factors may be useful for the design of contextualized interventions for this population.

ANTECEDENTES: La malnutrición es un problema mundial que afecta a niños escolares, capaz de incrementar el riesgo de enfermedades en la edad adulta. Adultos yaquis han presentado graves problemas de salud, por lo que los escolares podrían encontrarse en una situación similar. OBJETIVO: Evaluar el estado nutricional, el perfil lipídico y los factores asociados en una muestra de escolares yaquis. MATERIAL Y MÉTODOS: Se estudiaron 109 escolares habitantes de los pueblos originarios, en quienes se realizaron mediciones antropométricas, se extrajo una muestra de sangre venosa en condición de ayuno y se aplicaron cuestionarios. RESULTADOS: La prevalencia de sobrepeso/obesidad fue de 38.5 %, sin que se registraran casos de desnutrición crónica; 38.6 % de los escolares presentó dislipidemia. El consumo de fibra resultó ser un factor protector contra sobrepeso/obesidad y el consumo de grasa constituyó un factor de riesgo. La puntuación de actividad física resultó ser un factor protector contra dislipidemia y los factores de riesgo fueron puntuaciones Z del índice de masa corporal/edad, circunferencia de cintura, historia familiar de dislipidemias, nivel educativo y empleo permanente. CONCLUSIONES: Los escolares yaquis padecen por igual alta proporción de sobrepeso/obesidad y dislipidemia. Los factores asociados pueden resultar útiles para el diseño de intervenciones contextualizadas para esta población.

RESUMO

Oil has been extracted from the Western Amazon since the 1920s, leading to severe environmental contamination due to frequent occurrence oil spills and the dumping of produced water. Local inhabitants, along with environmental and human rights organizations, have reported the adverse effects of oil-related pollution on their livelihoods and the ecosystems they depend on. Here, we study accumulation of oil-related heavy metals in wildlife, and its subsequent incorporation into the trophic chain. We analysed the concentration of 14 heavy metals (Cd, Cr, Hg, As, Ni, V, Ba, Se, Be, Fe, Cu, Zn, Mn, Al) in liver samples from 78 lowland pacas (Cuniculus paca) hunted for subsistence in an oil-polluted area from the northern Peruvian Amazon where oil has been extracted since the 1970s (n = 38), and two control areas, the Yavari-Mirín River basin (n = 20), and the Pucacuro River basin (n = 20). Pacas in the oil-polluted area have significantly higher concentrations of Cd (P < 0.01) and Ba (P < 0.0001) compared to those in control areas, suggesting bioaccumulation of oil-related pollution. Conversely, Se levels were significantly lower in the oil-polluted area (P < 0.0001), likely due to the sequestration of Se by other heavy metals, particularly Cd. Additionally, minor variations in other heavy metals, e.g., Fe and Zn, were observed in pacas from the oil-polluted area, whereas control areas showed higher concentrations of Ni and Cu. Mn and Al levels did not significantly differ between the study areas. These results underscore the impact of oil extraction on the absorption and assimilation of heavy metals in wildlife, point at oil activities as the source of the high and unsafe blood Cd levels reported for the indigenous population of the studied oil extraction area and raise concerns about the long-term health risks from oil extraction posed to local Indigenous People who rely on subsistence hunting.

RESUMO

Despite legal safeguards, the Yanomami community faces challenges such as unauthorized incursions by gold miners, resulting in environmental degradation, particularly from mercury. This jeopardizes the health and food security of indigenous individuals, especially due to the consumption of contaminated fish. Ethnic and racial disparities persist in indigenous healthcare, marked by troubling health indicators such as malnutrition, anemia, and infectious diseases. This cross-sectional study, conducted in October 2022 in the Yanomami Indigenous Territory in the Amazon Forest, Brazil, presented clinical, laboratory, and neurodevelopmental findings in Yanomami children chronically exposed to methylmercury. The results revealed that Yanomami children exhibited weights and heights below expectations (median Z-scores of -1.855 for weight for age and -2.7 for height for age), a high prevalence of anemia (25%), low vaccination coverage (15%), and low IQ (average 68.6). The Total Hair Mercury (Total Hg) levels ranged from 0.16 µg/g to 10.20 µg/g (mean: 3.30 µg/g; median: 3.70 µg/g). Of 117 children tested, 93 children (79.4%) had levels ≥ 2.0 µg/g (had no significant difference between sex). Among the 58 children for whom it was possible to estimate the Total Intelligence Quotient (TIQ), the average value was 68.6, ranging from 42 to 92 points (median: 69.5; standard deviation: 10.5). Additionally, the lowest score on the IQ test was associated with 5 times the risk of having high levels of mercury in their hair, 2,5 fold the risk of having an older age, and almost 8 times the risk of consuming fish, adjusting for nut consumption. Notwithstanding the study's limitations, results suggest that mercury contamination from illegal mining activities on indigenous lands may negatively impact neurodevelopment in older indigenous children, particularly those fish consumers, despite the inherent benefits of fish consumption. Addressing other socio-environmental concerns is crucial for enhancing the overall health of the population.

RESUMO

BACKGROUND: Adverse Childhood Experiences (ACEs) have long-term consequences. The ACEs model has been extensively used in high-income countries. However, its effectiveness has yet to be demonstrated in low and middle-income countries and marginalized social groups. In indigenous populations, research has found inconsistent results in the prevalence and the relationship between ACEs and mental health outcomes. Therefore, the objectives of this study were 1) to determine the ACEs frequency among indigenous and non-indigenous Mexican adolescents; 2) to test the association between ACE scores and symptoms of Mental Health Problems (SMHP) in both groups; and 3) to review the ACEs model adequacy for the indigenous adolescents. PARTICIPANTS AND SETTINGS: Data from an online survey in 20 of the 32 states of Mexico were analyzed. We selected an 87 adolescent sample from indigenous families and 174 non-indigenous matched for age, sex, and state of residence, with a mean age of 16 years; 60 % were women. METHODS: ACE-IQ questionnaire and Youth Self Report instrument (eight SMHP) were used to collect data. ACEs' frequency was analyzed for each group, and Pearson correlations were used to identify the relationship between ACEs and SMHP. RESULTS: There was no statistical significance between Indigenous and non-Indigenous adolescents in the ACEs report. ACE scores were associated with eight SMHP. Correlations between ACE score and SMHP were higher in non-indigenous adolescents. CONCLUSIONS: ACEs were experienced similarly by both groups and were associated with mental health in all participants. Further research is needed to improve ACEs measurement in indigenous populations.

RESUMO

In Mexico, Indigenous people were hospitalised and killed by COVID-19 at a disproportionate rate compared to the non-Indigenous population. The main factors contributing to this were poor health conditions and impoverished social and economic circumstances within the country. The objective of this study is to examine the extent to which ethnic disparities are attributable to processes of structural discrimination and further explore the factors that exacerbate or mitigate them. Using administrative public data on COVID-19 and Census information, this study uses the Oaxaca-Blinder decomposition method to examine the extent to which disparities are illegitimate and signal discrimination against Indigenous people. The results show that although ethnic disparities were mainly attributable to observable differences in individual and contextual characteristics, 22.8% (p < 0.001) of the ethnic gap in hospitalisations, 17.5% in early deaths and 16.4% in overall deaths remained unexplained and could potentially indicate systemic discrimination. These findings highlight that pre-existing and longstanding illegitimate disparities against Indigenous people jeopardise the capacity of multi-ethnic countries to achieve social justice in health.

RESUMO

OBJECTIVES: To examine the rate of self-reported coronavirus disease-2019 (COVID-19) and its association with mental and cognitive health during the post-infection phase among middle-aged and older indigenous adults. METHODS: A cross-sectional study was conducted, including 141 individuals ≥50 and over from an urban indigenous community in Amazonas, Brazil. COVID-19 was deduced from self-reported infections. Cognitive function was evaluated using the Mini-Mental State Exam, Brief Cognitive Screening Battery (BCSB), and language fluency tests. Meanwhile, mental health was assessed through validated scales examining happiness, stress, and depression symptoms. The association between the rate of COVID-19 and cognitive and mental well-being was analyzed using logistic and linear regressions, adjusted for covariates. RESULTS: From March 2020 to February 2022, 65.2% of the urban indigenous group tested positive for COVID-19. Lower functional capacity decreased the odds of contracting COVID-19 (p = .03). Adjusted linear regression models showed that COVID-19 was associated with higher BCSB learning (p = .017) and delayed recall (p = .028). Women, higher age, lower functional capacity, and hospitalization were associated with worse cognitive performance (p < .05). No impact of mental health indicators on past COVID-19 infection was noted. DISCUSSION: COVID-19 was prevalent among urban Indigenous Brazilians. Unexpectedly, it was linked to enhanced learning and memory, not mental health issues. Cognitive performance was lower for men, older individuals, those with less functional ability, and hospitalized patients, indicating that participant characteristics and disease severity affect the COVID-19 and cognition relationship. Longitudinal studies across diverse Indigenous communities are necessary to understand COVID-19's impact on their cognitive and mental health.

RESUMO

Bat-mediated human rabies is a viral zoonotic disease that poses a serious threat to the public health of traditional peoples, especially indigenous populations that maintain primitive cultural and social habits, such as the Maxakali ethnic group, located in the southeastern region of Brazil. The sociocultural habit of this population led to the emergence between April and May 2022 of the viral spillover of rabies transmitted by bats, which decimated the lives of four children from this population who maintained contact with this animal as a recreational practice. Because the vampire bats Desmodus rotundus have exceptional ecology and social characteristics that can have important effects on the dynamics of viral dispersion in this indigenous population, I present the dynamics of contact between native children and the bat and the meaning of this relationship, which involves ritualistic and recreational significance. As important as knowing the reasons for this practice is discussing some intrinsic and extrinsic factors that imply risks that intensify the vulnerability of this population to the transmission of the rabies virus at any time. In view of this, I warn of the need to adopt efficient strategies to mitigate the risks of a new emergency in this region. Although emergency containment measures were carried out during the critical period of the outbreak, such animal and environmental control actions must become routine programmatic and structuring interventions. Essential for rabies surveillance in this population is to develop culturally adapted interethnic health education campaigns to guarantee the accessibility of the Maxakali indigenous people to the content taught, so that any attempt at domestication, captivity and recreational practices with bats of any species is discouraged, thus avoiding a possible re-emergence of this anthropozoonosis that has impacted not only the epidemiological scenario in this region, but throughout Brazil, and also throughout Latin America.

RESUMO

Objetivo: Analizar el patrón alimentario y el riesgo de deficiencia en la ingesta usual de energía y nutrientes de las mujeres gestantes y lactantes de algunos pueblos indígenas. Metodología: Estudio descriptivo transversal, con información del componente de ingesta dietética tomada del Estudio nacional de la situación alimentaria y nutricional de los pueblos indígenas de Colombia, realizado entre 2013 y 2019, que incluyó 1028 mujeres indígenas gestantes (319) y lactantes (709), de las regiones norte y sur del país. Resultados: Se encontró una proporción superior al 90 % (Desviación estándar = 0,04) de gestantes y lactantes con consumo inferior al recomendado de calorías (p= 0,038). Alrededor del 70 % de las gestantes y lactantes no consumió lácteos el día anterior a la encuesta, y 50 % no consumió frutas y verduras. Con respecto a los micronutrientes, se encontraron, en las gestantes y lactantes, altas prevalencias del riesgo de deficiencia en la ingesta de vitamina C (50,3 y 80,2 %), folatos (80,4 y 95,1 %), zinc (87,6 y 96,3 %), hierro (88,9 y 68,6 %) y calcio (87,5 y 98,5 %). Conclusión: El consumo de alimentos y nutrientes en las mujeres indígenas gestantes y lactantes es deficiente en nutrientes claves para mantener su estado de salud y proporcionar los nutrientes necesarios a su bebé, y su patrón alimentario se clasifica como no saludable.

Objective: To analyze the dietary pattern and deficiency risk in the usual energy and nutrient intake of pregnant and lactating women from some indigenous peoples. Methodology: Cross-sectional descriptive study, with information from the dietary intake component taken from the National Survey of the food and nutritional situation of indigenous peoples in Colombia, conducted between 2013 and 2019, which included 1,028 pregnant (319) and lactating (709) indigenous women from the northern and southern regions of the country. Results: A proportion higher than 90% (SD = 0.04) of pregnant and lactating women with lower than recommended calorie intake was found (p = 0.038). Around 70% of pregnant and lactating women had no any dairy products the day before the survey, and 50% did not eat fruits and vegetables. Regarding micronutrients, high prevalence of deficiency risk in the intake of vitamin C (50.3 and 80.2%), folate (80.4 and 95.1%), zinc (87.6 and 96.3%), iron (88.9 and 68.6%) and calcium (87.5 and 98.5%) was found in pregnant and lactating women. Conclusion: Food and nutrient intake in pregnant and lactating indigenous women is deficient in key nutrients to maintain their general health and provide the necessary nutrients to their babies. Their dietary pattern is considered unhealthy.

RESUMO

Introduction: Worldwide, expanding human activities continue to be a threat to many large-bodied species, including jaguars. As these activities continue, it is critical to understand how home range sizes will be impacted by human-modified landscapes. Objective: To evaluate the importance of protected and unprotected land on home-range size across their range. Methods: We used home range data from 117 jaguars in several habitat protection categories and human biome types. We used a Generalized Linear Mixed Model to test home range and spatial overlap with conservation categories and human biomes. Results: Most home-ranges were in Jaguar Conservation Units (62 %), followed by Protected Areas (21 %), Indigenous People's Lands (10 %) and Jaguar Movement Corridors (3 %), where 76 % of the jaguars lived inside one the first three conservation types. However, outside of conserved land, Rangeland, Cropland, Seminatural land and other human biomes were also important (24 % of the individuals). Jaguars in Rangeland, Cropland and Seminatural land had the largest home ranges. Conclusions: Although conservation land was dominant, human-impacted lands appear to play a considerable role in satisfying the spatial requirements of jaguars.

Introducción: A nivel mundial, la expansión de actividades humanas continúa teniendo un riesgo para muchas especies de cuerpo grande, tal como los jaguares. Conforme continúen estas actividades, es crucial entender el impacto de paisajes modificados sobre el tamaño de su territorio. Objetivo: Evaluar la importancia de terrenos protegidos y no protegidos sobre el tamaño de su territorio a lo largo de su rango. Métodos: Usamos datos de tamaño de los territorios de 117 jaguares en varias categorías de protección de hábitats y biomas humanos. Usamos un Modelo Mixto Lineal Generalizado para probar traslapes espaciales y de territorios con categorías de conservación y biomas humanos. Resultados: La mayoría de los territorios estaban en Unidades de Conservación de Jaguares (62 %), seguido por Áreas protegidas (21 %), Tierras de Pueblos Indígenas (10 %) y Corredores de Movimiento de Jaguares (3 %), en donde el 76 % de los jaguares vivían dentro de alguna de las primeras tres modalidades de conservación. Sin embargo, fuera de áreas protegidas, pastizales, tierras de cultivo, terrenos seminaturales y otros biomas humanos también fueron importantes (24 % de individuos). Jaguares en pastizales, tierras de cultivo, y terrenos seminaturales tuvieron territorios más grandes. Conclusiones: Aunque las áreas de conservación fueron dominantes, áreas con impacto humano parecieron jugar un rol considerable en satisfacer los requerimientos espaciales de los jaguares.

RESUMO

BACKGROUND: Women living in indigenous communities in Peru currently experience extremely high rates of intimate partner violence (IPV). Over the past 10 years, there has been a large multi-sectoral initiative to establish a national network of Centros de Emergencia de la Mujer (Women's Emergency Centres) that integrate health and police services, and substantial increase in efforts from non-governmental organisations in supporting survivors of violence. However, there is currently little evidence on how existing services meet the needs of indigenous women experiencing violence in Peru. METHODS: As part of a broader mixed-methods participatory VAWG prevention study, we assessed existing service provision for women experiencing violence in an indigenous Quechua community from Amantaní, Peru. This involved 17 key informant interviews with legal, government, police, and civil society representatives. We used the UN Women Essential Services Package for Women and Girls Subject to Violence framework to guide our analysis. RESULTS: Participants identified major gaps in existing services for indigenous women survivors of violence in Peru. They discussed survivors and perpetrators not being identified by the health system, a lack of IPV response training for health professionals, IPV not being prioritised as a health concern, and a lack of health services that are culturally appropriate for indigenous populations. Survivors who report to police are often treated poorly and discriminated against. Legal systems were perceived as insufficient and ineffective, with inadequate legal measures for perpetrators. While legal and policy frameworks exist, they are often not applied in practice. Service provision in this region needs to adopt an intercultural, rights based, gendered approach to IPV response and prevention, considering cultural and linguistic relevance for indigenous populations. CONCLUSION: The role of structural violence in perpetuating indigenous women's experiences of violence and undermining their access to services must be central to designing and implementing appropriate policies and services if they are to meet the needs of indigenous women in Peru.

RESUMO

In the Anthropocene, primate conservation can only take place when considering human culture, perspectives, and needs. Such approaches are increasingly important under the growing impact of anthropogenic activities and increasing number of threatened primates. The Amazon rainforest, rich in cultural and biological diversity, where indigenous people play a crucial role in primate conservation, provides ample opportunity to study human-primate interactions and the sociocultural context in which they occur. Human activities threaten the Amazon's fragile ecosystems and its primates, which play a key role in its maintenance and regeneration. This study focuses on one of the largest indigenous groups in the Peruvian Amazon: the Shipibo. Interviews and participant observation were used to investigate local perceptions of animal presence and depletion, food preferences, and how primates are incorporated into daily life and culture. Since time immemorial and still today, primates remain important in Shipibo culture, mythology, and subsistence. Local Shipibo participants consistently identified the presence of 13 species of primate. Primates were among the preferred species for consumption, pet keeping, and held a fundamental role in mythology, traditional knowledge, and storytelling. Large-bodied primates were often mentioned as being locally extinct, with reports and observations suggesting increasing consumption of smaller-bodied primates. Commonly perceived reasons for primate depletion include noise disturbance, hunting, and population growth, often in parallel. This study sheds light on the cultural context of an area rich in biodiversity, where primates, essential for ecological balance and integral to Shipibo lives and identity, are being depleted. We highlight the need for an inclusive ethnoprimatological approach to conserving primates and preserving indigenous heritage while improving local livelihoods.

RESUMO

Background: Previous studies in Australia, Canada, and Brazil, found that suicide among ethnic minority groups is higher than in the general population. Indigenous peoples in Brazil have been reported to have a high suicide rate, with reports of suicide clusters occurring in several communities. The objective of this study was to report trends in countrywide suicide rates among Indigenous peoples in Brazil between 2000 and 2020, and to compare these with the non-Indigenous population. Methods: This ecological study used Indigenous suicide data collected from all regions of Brazil during a 21-year period, between 2000 and 2020. We used suicide estimates from the Mortality Information System (SIM), available at the Brazilian Health Ministry website (DATASUS). Suicide mortality rates by state and region were calculated using the estimated Indigenous population from the 2010 census, and estimated population proportions for the other years. We performed a trend analysis and compared trends in suicide between the Indigenous and non-Indigenous population during the period studied. Findings: Suicide rates among Indigenous Brazilians have reached more than two and a half times the levels for the overall Brazilian population in 2020 (17.57 suicide deaths versus 6.35 suicide deaths per 100,000 inhabitants, respectively). The Central-West region of Brazil had the highest suicide rates among Indigenous Brazilians over the study period, reaching 58.8 deaths/100,000 inhabitants in 2008. The younger age group (10-24 years old) had the highest suicide rates for all the years studied. Time-series analyses showed a trend of statistically significant increases in suicide rates in Brazil for both the Indigenous and non-Indigenous population during the study period. The North region, and specifically Amazonas state, has shown a decisive increase in suicide rates among the Indigenous populations. The suicide rate for Indigenous people in Brazil, excluding cases in Amazonas and Mato Grosso do Sul states, were similar to those for the entire Brazilian population, showing that the Indigenous peoples who are the most vulnerable to suicide reside in these locations. Interpretation: While there were statistically significant increases in suicide rates for all Brazilians over the study period, they remained alarmingly high among Indigenous people, compared to their non-Indigenous counterparts. The high suicide rates among Indigenous people, and younger individuals in particular (aged between 10 and 24), reinforces the need for specific prevention strategies for these populations. Further studies should be concentrated on determining risk factors in distinct ethnic groups, specifically within regions experiencing an elevated risk, such as the states of Amazonas and Mato Grosso do Sul.

RESUMO

This study aims to document the diversity of medicinal plants used by the Cashinahua people (also known as Huni Kuin) of the Curanja River, as well as describe and compare their uses with pharmacological and phytochemical records from previously published studies. The ethnic has been studied to a limited extent from an ethnobotanical perspective. The study area is located in the Ucayali region, eastern Central Amazon, where ancestral knowledge is preserved due to the limited accessibility of the region. Between November 2010 and June 2015, a total of 11 months were spent on the survey, which included a short-term visit to complete voucher specimen collection and taxonomic identification. We conducted semi-structured interviews with 10 Cashinahua traditional healers and 10 midwives. Vernacular names, ethnomedicinal uses, plant parts used and forms of preparation and administration were recorded. Ethnopharmacological, pharmacological and phytochemical uses were checked through survey of the previously published papers indexed on Web of Science databases between 2018 and 2022. We obtained data on 467 plant taxa, among which we highlighted 79 species unreported or rarely cited for medicinal use or phytochemical analysis. These species were spread over 60 genera and 42 botanical families, with Acanthaceae being the most represented. Leaves were used the most frequently (93.56%). Among the 79 species, the most reported therapeutic activities involved pregnancy and birth disorders (13.84%), followed by poisonings, infections and infestations. The predominant application form was external (87%). Our study indicates that there are locally valuable species that have not yet been studied for their medical potential.

RESUMO

BACKGROUND: Syphilis is among the most common sexually transmitted infections worldwide. When it occurs during pregnancy, it can seriously affect the fetus and newborn`s health. The scarcity of studies on maternal and congenital syphilis in Indigenous Peoples remains an obstacle to its control in these populations. This study aimed to explore the breadth of the literature, map updated evidence, and identify knowledge gaps on maternal and congenital syphilis in Indigenous Peoples worldwide. METHODS: We conducted a Scoping review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Extension for Scoping Reviews. In March 2021, we collected data through a priority search on PubMed, Web of Science, Embase, and SciELO. RESULTS: The strategy yielded 24 studies for analysis. Data in the articles were collected from 1989 to 2020, half from 2015 onwards. Studies were in Oceania and the Americas, mainly in South America (66.7%), particularly in Brazil (50.0%). The topics assessed were Data quality related to maternal and congenital syphilis (20.8%); Diagnosis, provision, access, and use of health services (62.5%); Disease frequency and health inequities (54.2%); Determinants of maternal syphilis and congenital syphilis (20.8%); and Outcomes of maternal and congenital syphilis in the fetus (20.8%). The results show that the available literature on maternal and congenital syphilis is sparse and concentrated in some geographic areas; the frequency of these diseases in Indigenous Peoples varies but is generally higher than in the non-indigenous counterparts; the quality of surveillance data and health information systems is poor; multiple healthcare barriers exist; and the diversity of terms to identify Indigenous Peoples is a challenge to mapping scientific outputs on Indigenous Peoples' health. CONCLUSIONS: Maternal and congenital syphilis in Indigenous Peoples is a double-neglected condition and research in this area should be given the priority and encouragement it deserves globally. Reliable data and improving access to health care are needed to reduce the burden of syphilis and correctly inform policies and health services response to mitigate ethnic-racial inequalities in maternal and congenital syphilis.
