TL;DR: The clinical-epidemiological parameters evaluated for indigenous women point to the accentuated occurrence of nutrition transition in all regions of Brazil.
Abstract: 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.

TL;DR: In particular, a situacao dos povos indigenas in saude in Brazil is discussed in this article, where a preocupante invisibilidade demografica e epidemiologica resultante da ausencia de informacoes confiaveis for as populacoes indigena is discussed.
Abstract: No Brasil, nao ha uma producao sistematica acerca do peso da dimensao etnico-racial na expressao diferenciada dos agravos a saude. No cotidiano, minorias vivenciam situacoes de exclusao, marginalidade e discriminacao que as colocam em posicao de maior vulnerabilidade frente a agravos a saude. Neste texto e enfocada, em particular, a situacao dos povos indigenas. Coeficientes de morbi-mortalidade mais altos do que os registrados em nivel nacional, fome e desnutricao, riscos ocupacionais e violencia social sao apenas alguns dos multiplos reflexos sobre a saude decorrentes da persistencia de desigualdades. E importante que sejam realizados esforcos no sentido de reverter uma preocupante invisibilidade demografica e epidemiologica resultante da ausencia de informacoes confiaveis para as populacoes indigenas nas bases de dados oficiais. Isso possibilitara compreender melhor a genese, determinantes e formas de reproducao das desigualdades em saude no Brasil. Tais conhecimentos sao fundamentais para o embasamento tanto de atuacoes politicas, inclusive por parte de liderancas indigenas, como de intervencoes com vistas a promocao da equidade em saude.

TL;DR: This study shows that the Suruí are undergoing a rapid process of nutrition transition, closely associated with the emergence of intragroup differences in SES which have impacted diet and physical activity patterns.
Abstract: The purpose of this study was to assess the nutritional status of the adult Surui population, an indigenous society from the Brazilian Amazon, as it relates to socioeconomic conditions. Fieldwork was carried out in February-March 2005, including 252 individuals (88.1% of the total eligible subjects older than 20 years of age in the villages surveyed). Anthropometric measurements were performed following standard procedures, and percentage of body fat (%BF) was measured by bioimpedance. To classify the Surui according to socioeconomic status (SES), an index was constructed based on a group of variables to characterize socioeconomic differentiation. Evaluated by body mass index (BMI), the majority of Surui 20-49.9 years of age were overweight (42.3%) or obese (18.2%). The frequency of obesity for women (24.5%) was twice that recorded for men. Subjects classified as overweight or obese also showed high %BF and waist circumference (WC). Women in the high SES category showed higher anthropometric values (including weight, BMI, arm fat area, and WC) and %BF than those of lower SES. This study shows that the Surui are undergoing a rapid process of nutrition transition. This transition is closely associated with the emergence of intragroup differences in SES which have impacted diet and physical activity patterns. In research in indigenous peoples in Amazonia, greater attention should be paid to the human biological outcomes of socioeconomic transformations related to the growing involvement of native societies in the market economy.

TL;DR: Brazil has implemented major policies for the prevention of NCDs, and its age-adjusted NCD mortality is falling by 1·8% per year, however, the unfavourable trends for most major risk factors pose an enormous challenge and call for additional and timely action and policies.

TL;DR: The data suggest that in Brazil, at an individual level, color, as determined by physical evaluation, is a poor predictor of genomic African ancestry, estimated by molecular markers.
Abstract: This work was undertaken to ascertain to what degree the physical appearance of a Brazilian individual was predictive of genomic African ancestry. Using a panel of 10 population-specific alleles, we assigned to each person an African ancestry index (AAI). The procedure was able to tell apart, with no overlaps, 20 males from northern Portugal from 20 males from Sao Tome Island on the west coast of Africa. We also tested 10 Brazilian Amerindians and observed that their AAI values fell in the same range as the Europeans. Finally, we studied two different Brazilian population samples. The first consisted of 173 individuals from a rural Southeastern community, clinically classified according to their Color (white, black, or intermediate) with a multivariate evaluation based on skin pigmentation in the medial part of the arm, hair color and texture, and the shape of the nose and lips. In contrast to the clear-cut results with the African and European samples, our results showed large variances and extensive overlaps among the three Color categories. We next embarked on a study of 200 unrelated Brazilian white males who originated from cosmopolitan centers of the four major geographic regions of the country. The results showed AAI values intermediate between Europeans and Africans, even in southern Brazil, a region predominantly peopled by European immigrants. Our data suggest that in Brazil, at an individual level, color, as determined by physical evaluation, is a poor predictor of genomic African ancestry, estimated by molecular markers.
