Food Profiles of Indigenous Households in Brazil: Results of the First National Survey of Indigenous Peoples' Health and Nutrition.

The objective of the present study was to characterize the food profiles in Indigenous households participating in the First National Survey of Indigenous People's Health and Nutrition in Brazil. Multiple correspondence analysis was used to estimate distances between regions and foods from three sources (local Indigenous production, purchased, and external donation), in addition to "not consumed." The combined distribution of the first two dimensions revealed three distinct profiles of food acquisition. Observed proximities between geopolitical regions and distinct modes of food acquisition speak to regional contrasts in food sovereignty among the Indigenous population that are closely linked to historical occupation and economic expansion in the country. Considering the concept of food sovereignty as involving rights to dietary autonomy, healthy diets, and resource management, our data suggest Brazil's North region is the closest of the four regions analyzed to these goals. Food sovereignty in the Northeast and South/Southeast regions is reduced due to greater monetarization and proximity to market economy resources. The advance of agribusiness in the Amazon has been a hallmark of the Brazilian government's current environmental policy, directly threatening the survival of Indigenous peoples living in that region.

The Xavante Longitudinal Health Study in Brazil: Objectives, design, and key results.

OBJECTIVE: The Xavante Longitudinal Health Study was developed to permit granular tracking of contemporary health challenges faced by indigenous communities in Brazil, taking into consideration ongoing historical processes that may be associated with increases in child undernutrition, adult obesity, and cardiovascular disease risks. METHODS: This was an open-cohort study with six semiannual data collection waves from 2009 to 2012. The study was undertaken in two Xavante villages, Pimentel Barbosa and Etênhiritipá, State of Mato Grosso, Central Brazil. No sampling technique was used. Data collection placed emphasis on growth and nutrition of children under five and nutrition status, blood pressure, and blood glucose levels of adolescents and adults. RESULTS: Baseline data collection began in July/August 2009 with a population census (656 individuals). Between the first and final waves, the study population increased by 17%. At baseline, stunting and wasting was elevated for most age groups <10 years. Overweight, obesity, and increased risk of metabolic complications were expressive among individuals >17 years, disproportionately affecting females. Anemia was elevated in most age groups, especially among females. Mean systolic and diastolic blood pressure was moderate. The overall prevalence of high blood pressure was relatively low. CONCLUSIONS: Our findings reveal marked health disparities relative to the Brazilian national population and a complex dietary health epidemiology involving the double burden of malnutrition, rapidly changing nutritional indicators, and elevated metabolic disease risk. The topically broad multidisciplinary focus permitted construction of the richest longitudinal data set of socio-epidemiological information for an indigenous population in Brazil.

Indigenous and tribal peoples' health (The Lancet-Lowitja Institute Global Collaboration): a population study.

BACKGROUND: International studies of the health of Indigenous and tribal peoples provide important public health insights. Reliable data are required for the development of policy and health services. Previous studies document poorer outcomes for Indigenous peoples compared with benchmark populations, but have been restricted in their coverage of countries or the range of health indicators. Our objective is to describe the health and social status of Indigenous and tribal peoples relative to benchmark populations from a sample of countries. METHODS: Collaborators with expertise in Indigenous health data systems were identified for each country. Data were obtained for population, life expectancy at birth, infant mortality, low and high birthweight, maternal mortality, nutritional status, educational attainment, and economic status. Data sources consisted of governmental data, data from non-governmental organisations such as UNICEF, and other research. Absolute and relative differences were calculated. FINDINGS: Our data (23 countries, 28 populations) provide evidence of poorer health and social outcomes for Indigenous peoples than for non-Indigenous populations. However, this is not uniformly the case, and the size of the rate difference varies. We document poorer outcomes for Indigenous populations for: life expectancy at birth for 16 of 18 populations with a difference greater than 1 year in 15 populations; infant mortality rate for 18 of 19 populations with a rate difference greater than one per 1000 livebirths in 16 populations; maternal mortality in ten populations; low birthweight with the rate difference greater than 2% in three populations; high birthweight with the rate difference greater than 2% in one population; child malnutrition for ten of 16 populations with a difference greater than 10% in five populations; child obesity for eight of 12 populations with a difference greater than 5% in four populations; adult obesity for seven of 13 populations with a difference greater than 10% in four populations; educational attainment for 26 of 27 populations with a difference greater than 1% in 24 populations; and economic status for 15 of 18 populations with a difference greater than 1% in 14 populations. INTERPRETATION: We systematically collated data across a broader sample of countries and indicators than done in previous studies. Taking into account the UN Sustainable Development Goals, we recommend that national governments develop targeted policy responses to Indigenous health, improving access to health services, and Indigenous data within national surveillance systems.

Anemia among indigenous women in Brazil: findings from the First National Survey of Indigenous People's Health and Nutrition.

BACKGROUND: Anemia is recognized as a major public health problem that disproportionately affects vulnerable populations. Indigenous women of reproductive age in Brazil are thought to be at high risk, but lack of nationwide data limits knowledge about the burden of disease and its main determinants. This study aimed to assess the prevalence of anemia and associated factors in this population using data from The First National Survey of Indigenous People's Health and Nutrition in Brazil. METHODS: Data were collected from Indigenous women between 15 and 49 years old based on a nationwide sample of villages. The outcomes of interest were hemoglobin levels (g/dL) and anemia (< 12 g/dL for nonpregnant and < 11 g/dL for pregnant women). Multilevel models were used to explore associations with contextual (village) and individual (household/woman) level variables. RESULTS: Based on data for 6692 Indigenous women, the nationwide mean hemoglobin level was 12.39 g/dL (95% CI: 12.29-12.50). Anemia prevalence was high (33.0%; 95% CI: 30.40-35.61%) and showed pronounced regional disparities. No village-level characteristics were associated with anemia or hemoglobin levels in the multilevel model. Even after controlling for upper level variables, socioeconomic status, parity, body mass index, and having been treated for malaria were associated with anemia and hemoglobin levels. CONCLUSION: The prevalence of anemia in Brazilian Indigenous women was 12% greater than the national estimates for women of reproductive age. Anemia prevalence and mean hemoglobin levels among Indigenous women appear to be partly explained by some previously recognized risk factors, such as socioeconomic status, body mass index, and malaria; however, part of the variability in these outcomes remains unexplained. Knowledge of health status and its potential determinants is essential to guide public policies aimed at controlling anemia burden in Indigenous communities.

Physical growth curves of indigenous Xavante children in Central Brazil: results from a longitudinal study (2009-2012).

BACKGROUND: The nutritional profile of Indigenous children in Brazil is comparable to those observed in some of the least developed regions of the world. AIM: Weight and height growth curves were characterised based on longitudinal data from a local Indigenous population experiencing the double burden of child under-nutrition and adult obesity. SUBJECTS AND METHODS: Anthropometric data were collected in six waves from 2009-2011 for children <10 in two proximate Xavante villages in Central Brazil. Prevalence rates for stunting, wasting and thinness were calculated using WHO references. Weight and height data were adjusted for generalised additive mixed models to generate growth curves. RESULTS: Prevalence rates of stunting and wasting were high, but cases of thinness and excess weight were negligible. Weight and height began close to WHO medians, but fell substantially before 12 months. Boys but not girls were able to catch-up in weight before age 10. From 3-10 years, height for both sexes remained between -2 and 0 z-scores. CONCLUSION: Impaired Xavante growth before 1 year followed by inconsistent recovery before 10 years reflects health and wellbeing disparities with regard to the Brazilian national population and a complex epidemiology of growth involving rapid nutritional change.

Hospital morbidity due to paracoccidioidomycosis in Brazil (1998-2006).

OBJECTIVE: To analyse hospital morbidity records due to paracoccidioidomycosis in Brazil, including its nationwide distribution in time and space, as well as key epidemiological and sociodemographic characteristics. METHODS: Descriptive analysis of hospital morbidity records due to paracoccidioidomycosis covering the period January 1998 to December 2006. Hospital records were obtained from the Hospital Information System of the Brazilian Unified Health System (SIH/SUS). RESULTS: There were 6732 hospitalisations (82% male) due to paracoccidioidomycosis in the period, representing 4.3 per 1.0 million inhabitants. Admissions due to this mycosis were recorded in 27% of the 5560 Brazilian municipalities, covering 35% of the country. Ten municipalities concentrated 52% of all admissions. The temporal distribution of admissions for paracoccidioidomycosis showed a slight increase. The geographical analysis showed two distinct patterns of the disease: (i) traditional areas of southern and south-eastern regions, covering 60% of admissions, and (ii) a second pattern in northern Brazil revealed a transverse band of higher concentration with about 27% of admissions, particularly along the southern border of the Amazon region. CONCLUSION: This first nationwide analysis of hospitalisation due to paracoccidioidomycosis in Brazil shows that it is the most prevalent systemic mycosis in Brazil. Despite its importance, there are major deficits in its proper registry, diagnostics and treatment. The particular epidemiological and medical challenges of paracoccidioidomycosis will not be met while the disease continues to be perceived as an isolated infectious entity restricted to a few faraway regions of the globe.

Diarrhea and health inequity among Indigenous children in Brazil: results from the First National Survey of Indigenous People's Health and Nutrition.

BACKGROUND: Globally, diarrhea is the second leading cause of death among children under five. In Brazil, mortality due to diarrhea underwent a significant reduction in recent decades principally due to expansion of the primary healthcare network, use of oral rehydration therapy, reduced child undernutrition, and improved access to safe drinking water. The First National Survey of Indigenous People's Health and Nutrition in Brazil, conducted in 2008-2009, was the first survey based on a nationwide representative sample to study the prevalence of diarrhea and associated factors among Indigenous children in the country. METHODS: The survey assessed the health and nutritional status of Indigenous children < 5 years of age based on a representative sample of major Brazilian geopolitical regions. A stratified probabilistic sampling was carried out for Indigenous villages. Within villages, children < 5 years of age in sampled households were included in the study. Interviews were based on a seven day recall period. Prevalence rates of acute diarrhea were calculated for independent variables and hierarchical multivariable analyses were conducted to assess associations. RESULTS: Information on diarrhea was obtained for 5,828 children (95.1% of the total sample). The overall prevalence of diarrhea was 23.5%. Regional differences were observed, with the highest rate being in the North (38.1%). Higher risk of diarrhea was observed among younger children and those who had less maternal schooling, lower household socioeconomic status, undernutrition (weight-for-age deficit), presence of another child with diarrhea in the household, and occurrence of upper respiratory infection. CONCLUSIONS: According to results of the First National Survey of Indigenous People's Health and Nutrition, almost a quarter of Indigenous children throughout the country had diarrhea during the previous week. This prevalence is substantially higher than that documented in 2006 for Brazilian children < 5 years generally (9.4%). Due to its exceedingly multicausal nature, the set of associated variables that remained associated with child diarrhea in the final multivariable model provide an excellent reflection of the diverse social and health inequities faced by Indigenous peoples in contemporary Brazil.

Risk factors for hospital admission due to acute lower respiratory tract infection in Guarani indigenous children in southern Brazil: a population-based case-control study.

OBJECTIVE: To assess risk factors associated with hospital admission due to acute lower respiratory tract infection (ALRTI) in indigenous Guarani children <5 years of age in southern Brazil. METHODS: Population-based matched case-control study from May 2007 to June 2008 in 81 Guarani villages. Cases were defined as hospital admissions due to confirmed ALRTI. Two controls free from acute respiratory infection, matched according to age, sex and place of residence, were selected for each case at the time of the case's hospitalisation. Both cases and controls were recruited by a surveillance routine established for the study. RESULTS: The analysis was performed on 120 cases and 201 controls. The risk factors that remained significantly associated with hospitalisation due to ALRTI in the hierarchical multivariate conditional logistic regression were: low stable monthly per capita household income (

Nutritional status of indigenous children: findings from the First National Survey of Indigenous People's Health and Nutrition in Brazil.

INTRODUCTION: The prevalence of undernutrition, which is closely associated with socioeconomic and sanitation conditions, is often higher among indigenous than non-indigenous children in many countries. In Brazil, in spite of overall reductions in the prevalence of undernutrition in recent decades, the nutritional situation of indigenous children remains worrying. The First National Survey of Indigenous People's Health and Nutrition in Brazil, conducted in 2008-2009, was the first study to evaluate a nationwide representative sample of indigenous peoples. This paper presents findings from this study on the nutritional status of indigenous children < 5 years of age in Brazil. METHODS: A multi-stage sampling was employed to obtain a representative sample of the indigenous population residing in villages in four Brazilian regions (North, Northeast, Central-West, and Southeast/South). Initially, a stratified probabilistic sampling was carried out for indigenous villages located in these regions. Households in sampled villages were selected by census or systematic sampling depending on the village population. The survey evaluated the health and nutritional status of children < 5 years, in addition to interviewing mothers or caretakers. RESULTS: Height and weight measurements were taken of 6,050 and 6,075 children, respectively. Prevalence rates of stunting, underweight, and wasting were 25.7%, 5.9%, and 1.3%, respectively. Even after controlling for confounding, the prevalence rates of underweight and stunting were higher among children in the North region, in low socioeconomic status households, in households with poorer sanitary conditions, with anemic mothers, with low birthweight, and who were hospitalized during the prior 6 months. A protective effect of breastfeeding for underweight was observed for children under 12 months. CONCLUSIONS: The elevated rate of stunting observed in indigenous children approximates that of non-indigenous Brazilians four decades ago, before major health reforms greatly reduced its occurrence nationwide. Prevalence rates of undernutrition were associated with socioeconomic variables including income, household goods, schooling, and access to sanitation services, among other variables. Providing important baseline data for future comparison, these findings further suggest the relevance of social, economic, and environmental factors at different scales (local, regional, and national) for the nutritional status of indigenous peoples.

The First National Survey of Indigenous People's Health and Nutrition in Brazil: rationale, methodology, and overview of results.

BACKGROUND: Although case studies indicate that indigenous peoples in Brazil often suffer from higher morbidity and mortality rates than the national population, they were not included systematically in any previous national health survey. Reported here for the first time, the First National Survey of Indigenous People's Health and Nutrition in Brazil was conducted in 2008-2009 to obtain baseline information based on a nationwide representative sample. This paper presents the study's rationale, design and methods, and selected results. METHODS: The survey sought to characterize nutritional status and other health measures in indigenous children less than 5 years of age and indigenous women from 14 to 49 years of age on the basis of a survey employing a representative probabilistic sample of the indigenous population residing in villages in Brazil, according to four major regions (North, Northeast, Central-West, and South/Southeast). Interviews, clinical measurements, and secondary data collection in the field addressed the major topics: nutritional status, prevalence of hypertension and diabetes mellitus in women, child hospitalization, prevalence of tuberculosis and malaria in women, access to health services and programs, and characteristics of the domestic economy and diet. RESULTS: The study obtained data for 113 villages (91.9% of the planned sample), 5,305 households (93.5%), 6,692 women (101.3%), and 6,128 children (93.1%). Multiple household variables followed a pattern of greater economic autonomy and lower socioeconomic status in the North as compared to other regions. For non-pregnant women, elevated prevalence rates were encountered for overweight (30.3%), obesity (15.8%), anemia (32.7%), and hypertension (13.2%). Among children, elevated prevalence rates were observed for height-for-age deficit (25.7%), anemia (51.2%), hospitalizations during the prior 12 months (19.3%), and diarrhea during the prior week (23.6%). CONCLUSIONS: The clinical-epidemiological parameters evaluated for indigenous women point to the accentuated occurrence of nutrition transition in all regions of Brazil. Many outcomes also reflected a pattern whereby indigenous women's and children's health indicators were worse than those documented for the national Brazilian population, with important regional variations. Observed disparities in health indicators underscore that basic healthcare and sanitation services are not yet as widely available in Brazil's indigenous communities as they are in the rest of the country.

Nutritional status and growth of indigenous Xavante children, Central Brazil.

BACKGROUND: The aim of this study was to characterize the nutritional status of Xavante Indian children less than 10 years of age in Central Brazil and to evaluate the hypothesis of an association between child nutrition and socioeconomic differentiation in this population. METHODS: A cross-sectional study was conducted in July 2006 that included all children under the age of 10 from the Xavante village Pimentel Barbosa in Mato Grosso, Brazil. The data collected included weight, height, and sociodemographic information. Sociodemographic data were used to generate two indices ("income" and "wealth") and to determine the proportion of adults in each household. Descriptive analyses were performed for weight-for-age (W/A), height-for-age (H/A), and weight-for-height (W/H) using the NCHS and the WHO growth references. Univariate and multivariate analyses were conducted using H/A and W/A as a response variables. RESULTS: Of a total of 246 children under the age of ten residing in the village, 232 (94.3%) were evaluated. Following the NCHS reference, 5.6% of children under the age of ten presented low W/A and 14.7% presented low H/A. Among children under the age of five, deficit percentages for weight and height were 4.5% and 29.9%, respectively, following the WHO curves. Among children < 2 years of age, H/A index variability was found to be directly related to child's age and inversely related to the proportion of adults in the household. Maternal BMI was positively associated with growth for children from 2 to 4 years of age, explaining 11.5% of the z-score variability for the H/A index. For children 5 years of age and older, the wealth index and maternal height were positively associated with H/A. No significant associations were found using W/A as the dependent variable. CONCLUSION: This study demonstrated that undernutrition, in particular linear growth deficit, is a notable health issue for Xavante children. These findings contrast with the nutritional profile observed among Brazilian children nationally, which is characterized by a sharp decline in child undernutrition in recent decades, even in the poorest regions of the country. This discrepancy calls attention to the persistent health disparities that exist between indigenous and non-indigenous people in Brazil.

A'uwe (Xavante) views of food security in a context of monetarization of an indigenous economy in Central Brazil.

Following boom-and-bust economic cycles provoked by Brazilian governmental attempts to integrate Indigenous peoples into national society, it is approximately since the beginning of the 2000s that Brazilian Indigenous peoples came to be viewed officially as "poor" and victims of "hunger." Consequently, the national indigenist agency and other State entities started to conceive and implement diverse initiatives that ultimately injected money and resources into Indigenous communities. In 2019 we undertook an ethnographic study in three A'uwe (Xavante) communities in the Pimentel Barbosa Indigenous Reserve, Central Brazil, with the objective of analyzing how people understand and pursue food security. We propose that in the studied communities the complex network of A'uwe food reciprocity is a fundamental strategy for mitigating hunger and acute lack of food. We show that among the A'uwe, the hybrid economy that developed since the 1970s has proved resilient to dramatic transformations and uncertainty in the availability and characteristics of external government inputs.

Coping with Hypertension among Indigenous Peoples in Brazil and the Role of the Primary Care Nurse: A Critical Review from a Transcultural Perspective.

Our objective is to critically review the literature addressing the strategic role of nurses in the daily primary care of arterial hypertension in Indigenous communities in Brazil. We selected studies based on an initial keyword search of major bibliographic indexing databases for the years 2000 to 2020 and manual search. Further selection was based on topical, methodological, and thematic relevance, as well as evaluation of scholarship quality and pertinence to our chosen narrative. The literature demonstrates Indigenous peoples do not receive health services that measure up to national standards in large part due to a marked lack of academic and employer preparation for nurses operating in transcultural settings. Inequities were apparent in recurrent reports of victim-blaming, deficient clinical communication with patients, clinical malpractice, devaluation of hypertension as a problem for Indigenous peoples, insufficient intercultural training for nurses, and discrimination against Indigenous students in nursing education programs. This systemic problem needs to be addressed by universities and the Indigenous Health Care Subsystem in Brazil.

Indigenous migration patterns in Brazil based on the 2010 national demographic census: analysis and critical reflection.

Research in several Latin American countries points to violence, loss of traditional territories, and seeking education, health, and wage labor as key variables in triggering rural-urban migration among Indigenous people. This study presents an analysis of the migration patterns of Indigenous people in Brazil, compared to non-indigenous people, based on data from the most recent national census, conducted in 2010. Migration characteristics related to lifetime migration and recent migration were investigated by means of descriptive and multivariable logistic regression analyses. The findings pointed to complex mobility scenarios according to migrants' Indigenous status and geographical regions of origin and destination. Indigenous people living in urban areas presented high levels of mobility (approximately 50% lived in different municipalities from those where they were born), which were more pronounced than those of non-Indigenous people. Indigenous people living in rural areas presented the lowest levels of migration (approximately 90% residing in their municipality of birth). Statistical modeling confirmed the patterns observed in descriptive analysis, highlighting the marked mobility of Indigenous subjects in urban areas. We emphasize the limitations of using census data for characterizing Indigenous mobility profiles, although no other nationally representative data are available. The finding that the Indigenous population living in urban areas presents rates of migration higher than their non-Indigenous counterparts is particularly important for the planning and implementation of a broad range of public policies aimed at ethnic minorities in the country, including health, education, and housing initiatives.

Tuberculosis among the Xavante Indians of the Brazilian Amazon: an epidemiological and ethnographic assessment.

BACKGROUND: Despite broad availability of a national tuberculosis (TB) control program that has proved effective in Brazil, TB remains a major cause of morbidity and mortality among indigenous peoples. AIM: We report the results of an interdisciplinary investigation of TB epidemiology, healthcare services, and ethnomedicine among the Xavante Indians of Central Brazil. SUBJECTS AND METHODS: Fieldwork components included clinical assessment of TB (479 subjects, 89.3% of the population = 1 year of age), analysis of medical health records, and ethnographic research. RESULTS: We found TB to constitute a major health risk, with moderately high annual risk of infection (0.94%), moderate prevalence of infection, high percentage of X-ray images suggestive of TB (14.2% in subjects > or = 10 years of age), and a relatively low percentage of individuals with reactive TB skin tests (16.6% of reactions > or = 10 mm) despite high BCG vaccine coverage. We also found a high rate of TB patients showing no evidence of prior infection. Ethnographic interviews show that Xavante and biomedical health perspectives are simultaneously divergent in their etiologies but pragmatically compatible. CONCLUSION: Ineffective diagnosis procedures compromise the efficacy of existing TB prevention efforts and threaten to undermine otherwise favorable institutional and cultural conditions.

[Profile of antineoplastic medication among indigenous people treated in the Brazilian Unified National Health System]. / Perfil de utilização de medicamentos antineoplásicos entre indígenas atendidos pelo Sistema Único de Saúde.

Brazil has an estimated 900,000 indigenous people (0.4% of the country's population), belonging to more than 300 different ethnic groups. However, information is scarce on cancer epidemiology and the antineoplastic drugs used in treatment of these individuals. The study's objectives are to identify the antineoplastic drugs used and to describe the profile of use of these drugs in the indigenous population treated in Brazil, as well as to describe the patients' epidemiological profile. An ecological study was performed involving outpatient chemotherapy care from January 2014 to December 2018 throughout Brazil. The data source was the Outpatient Information System of the Brazilian Health Informatics Department, considering only Authorizations for High-Complexity Chemotherapy Procedures. We identified 2,425 authorizations for chemotherapy procedures for treatment of indigenous patients. Of these, 2,292 authorizations for a total of 210 individuals were analyzed. We found an increase in the number of authorizations and of indigenous persons receiving chemotherapy over the period, with a higher concentration of individuals living in and receiving treatment in the South of Brazil, plus a wide diversity in the types of diagnosed tumors (n = 63) and of treatment regimen used during the treatment (n = 107). The current study provided a new overview of the epidemiological profile of indigenous patients receiving chemotherapy in the Brazilian Unified National Health System. The findings help fill a current knowledge gap on indigenous people's health in Brazil.

Estima-se que no Brasil existam cerca de 900 mil indígenas (0,4% da população do país) pertencentes a mais de 300 etnias diferentes. Porém, informações sobre a epidemiologia do câncer e sobre os medicamentos antineoplásicos utilizados no tratamento desses indivíduos são escassas. Os objetivos do presente estudo são identificar os medicamentos antineoplásicos utilizados e descrever o perfil de utilização deles na população indígena tratada no Brasil, além de descrever o perfil epidemiológico dos usuários. Foi realizado um estudo do tipo ecológico que envolveu os atendimentos ambulatoriais de quimioterapia, realizados no período de janeiro de 2014 e dezembro de 2018, em todo o Brasil. A fonte de coleta dos dados utilizada foi o Sistema de Informação Ambulatorial, do Departamento de Informática do SUS, considerando apenas as Autorizações de Procedimentos de Alta Complexidade para Quimioterapia. Foram identificadas 2.425 autorizações para procedimentos de quimioterapia destinadas ao tratamento de pacientes indígenas. Um total de 2.292 autorizações, para um total de 210 indivíduos, foram analisadas. Observou-se um aumento do número de autorizações e de indígenas em uso de quimioterapia ao longo do período, maior concentração de indivíduos residentes e em tratamento na Região Sul do país, diversidade de tipos de tumores diagnosticados (n = 63) e de esquemas terapêuticos utilizados durante o tratamento (n = 107). O presente estudo trouxe um novo panorama sobre o perfil epidemiológico dos usuários indígenas sob tratamento quimioterápico no Sistema Único de Saúde. Os achados contribuem para o preenchimento da atual lacuna de conhecimento a respeito da saúde indígena no Brasil.

El presente estudio presentó un nuevo panorama sobre el perfil epidemiológico de los usuarios indígenas bajo tratamiento quimioterápico en el Sistema Único de Salud. Los hallazgos contribuyen a llenar la actual laguna de conocimiento con respecto a la salud indígena en Brasil.

Indigenous children and adolescent mortality inequity in Brazil: What can we learn from the 2010 National Demographic Census?

Indigenous peoples worldwide are highly disadvantaged compared to national baseline populations. Given historical challenges to accessing relevant data for Brazil, the present study innovates by using 2010 Brazilian National Demographic Census data to estimate mortality curves in Indigenous children and adolescents <20 years. The non-parametric smoothing approach TOPALS (tool for projecting age-specific rates using linear splines) was employed. Analyses included stratifications by sex, rural or urban residence, and geopolitical region. The mortality of children and adolescents classified as Indigenous was higher for all analyzed strata. Mortality of Indigenous and non-Indigenous individuals in rural areas was higher than those in urban areas in almost all strata analyzed. Mortality levels in the Indigenous segment exceed those of children and adolescents classified as non-Indigenous in all four geopolitical regions, with few exceptions. This is the first study to compare mortality curves of children and adolescents in Brazil according to social variables based on national census data. More Indigenous children and adolescents die than their non-Indigenous counterparts, including those classified as black or brown, in both rural and urban residential settings. Indigenous children and adolescents are consistently at the most disadvantaged end of a marked gradient of ethnic-racial inequality in Brazil, independently of sex, age, and geopolitical region.

Caries, gender and socio-economic change in the Xavante Indians from Central Brazil.

BACKGROUND: The oral health conditions of indigenous peoples in Amazonia are closely associated with ecological and dietary changes related to interaction with non-Indians. AIM: The study investigated the incidence of caries in an indigenous community from Central Brazil focusing on gender differences. SUBJECTS AND METHODS: The research was conducted among the Xavante Indians and was based on longitudinal data collected in two surveys (1999 and 2004). The study included 128 individuals, 63 (49.2%) males and 65 (50.8%) females, divided in four age brackets (6-12, 13-19, 20-34, 35-60 years of age). The DMFT (decayed, missing and filled teeth) index and incidences (difference between 1999 and 2004) were calculated for each individual. The proportion of incidence was also calculated. Differences in caries risk between gender and age brackets were compared by parametric and non-parametric tests. RESULTS: There were statistically significant differences in relation to caries incidence between age brackets and gender. The greatest incidence was observed in the 20-34 age bracket, which presented 3.30 new decayed teeth, twice the risk of the 6-12 age bracket (p<0.01), chosen as reference. While females in most age groups did not show higher risk for caries when compared to males, there was a 4.04-fold risk in the 20-34 age bracket (p<0.01). CONCLUSION: It is concluded that factors related to the social functions of each sex (gender issues) and differential access to information, health services, and education may help to understand the differences observed in the incidence of caries.

[Excess weight in Xukuru indigenous children in Ororubá, Pernambuco State, Brazil: magnitude and associated factors]. / Excesso de peso em crianças indígenas Xukuru do Ororubá, Pernambuco, Brasil: magnitude e fatores associados.

The few studies on health and nutrition in indigenous peoples in Northeast Brazil point to some differences with indigenous peoples in the North and Central of the country. This study estimated the prevalence rates and risk of overweight and excess weight in Xukuru children in the village of Ororubá, Pernambuco State, and assessed the socioeconomic and demographic factors potentially associated with these conditions. This cross-sectional study analyzed the associations between adequate weight, excess weight (overweight and obesity), and risk of overweight according to the indices and cutoff points of the World Health Organization for children and the explanatory variables, using multinomial logistic regression. Prevalence of excess weight was 7.7% and risk of overweight was 24.2%. The odds of risk of overweight and excess weight were higher in children < 2 years. Children of obese mothers showed higher odds of excess weight. Prevalence of risk of overweight was 97% higher when compared to households with fixed income. The findings suggest that the Xukuru are experiencing an accelerated nutritional transition, with a paradoxical situation to which other indigenous peoples in Brazil are also exposed.

Os poucos estudos que abordam o tema de saúde e nutrição em indígenas da macrorregião Nordeste do Brasil sinalizaram situações diferenciadas em alguns aspectos, quando comparados principalmente à realidade de indígenas do Norte e Centro-oeste. Este trabalho objetivou estimar a magnitude das prevalências e risco de sobrepeso e excesso de peso em crianças menores de dez anos da etnia Xukuru do Ororubá, Estado de Pernambuco, e avaliar os fatores socioeconômicos e demográficos potencialmente associados a estes agravos. Estudo transversal, no qual realizou-se uma análise da associação entre as variáveis de desfecho, peso adequado, excesso de peso (sobrepeso e obesidade) e risco de sobrepeso, de acordo com os índices e pontos de corte da Organização Mundial da Saúde para crianças e as variáveis explicativas, utilizando-se regressão logística multinomial. A prevalência de excesso de peso foi de 7,7% e de risco de sobrepeso de 24,2%. As chances de risco de sobrepeso e de excesso de peso são maiores em crianças < 2 anos, e filhos de mães obesas apresentam maior chance de excesso de peso. A prevalência de risco de sobrepeso foi 97% maior quando comparada com os domicílios sem renda fixa. Os achados sugerem que os Xukuru estão atravessando um acelerado processo de transição nutricional, com uma situação paradoxal a que outros povos indígenas no Brasil estão expostos.

Los escasos estudios que abordan el tema de salud y nutrición en indígenas de la macrorregión Nordeste de Brasil mostraron situaciones diferenciadas en algunos aspectos, cuando se comparan principalmente con la realidad de los indígenas del Norte y Centro-oeste. El objetivo de este trabajo fue estimar la magnitud de las prevalencias y riesgo de sobrepeso, así como de exceso de peso en niños menores de diez años de la etnia Xukuru do Ororubá, estado de Pernambuco, y evaluar los factores socioeconómicos y demográficos potencialmente asociados a estos problemas. Se trata de un estudio transversal, en el que se realizó un análisis de la asociación entre las variables de desenlace, peso adecuado, exceso de peso (sobrepeso y obesidad) y riesgo de sobrepeso, conforme los índices y puntos de corte de la Organización Mundial de la Salud para niños, y las variables explicativas, utilizando una regresión logística multinomial. La prevalencia de exceso de peso fue de un 7,7% y la de riesgo de sobrepeso de 24,2%. Las oportunidades de riesgo de sobrepeso y de exceso de peso son mayores en niños < 2 años, asimismo, hijos de madres obesas presentan una mayor oportunidad de exceso de peso. La prevalencia de riesgo de sobrepeso fue un 97% mayor cuando se compara con domicilios sin ingresos fijos. Los resultados sugieren que los Xukuru están atravesando un acelerado proceso de transición nutricional, con una situación paradójica a la que otros pueblos indígenas en Brasil están expuestos.
