13. Saúde e nutrição Teréna: sobrepeso e obesidade
A qualidade de vida nas comunidades indígenas vem sofrendo inúmeras modificações devido ao maior contato com o meio urbano e redução territorial, fatos que influenciam na saúde da população. Através de estudo transversal com o objetivo de analisar as condições de saúde e nutrição da população adulta residente na Aldeia Buriti, MS, identifico

15. The demographic revolution of the Brazilian Indians: the experience of the Kaiabi a indigenous people of the Xingu river (Mato Grosso), 1970-1999 / A revolução demográfica dos povos indígenas do Brasil: a experiência dos Kaiabi do Parque Indígena do Xingu - Mato Grosso - 1970-1999
Objective. This study analyses the demographic dynamic of the Kaiabi a indigenous people of the Xingu river, Mato Grosso, Brazil, from 1970 to 1999. Methods. The demographic survey included cohort and period analyse, with vital statistics from the health service of the Xingu Indigenous Park. Results. Contact with Brazilian national society, established in th

16. Physical Activity and Incident Diabetes in American Indians: The Strong Heart Study
The authors examined the association between total physical activity (leisure-time plus occupational) and incident diabetes among 1,651 American Indians who participated in the Strong Heart Study, a longitudinal study of cardiovascular disease and its risk factors among 13 American Indian communities in 4 states (North Dakota, South Dakota, Oklahoma, and Ari

17. Village and Tribal Genetic Distances among American Indians, and the Possible Implications for Human Evolution*
Pair-wise genetic distances based on six genetic systems (Rh, MNSs, Kidd, Duffy, Diego, and haptoglobins) are presented for seven villages of Makiritare Indians, seven villages of Yanomama Indians, and 12 Indian tribes of Central and South America. It is shown that the mean genetic distance between Indian villages is 85-90 per cent of the distance between tr

18. The Genetic Structure of a Tribal Population, the Yanomama Indians. Xiv. Clines and Their Interpretation
The Yanomama Indians are a South American tribe distributed over an irregular area approximately 200 x 300 miles. The gene frequencies observed at 12 loci in 47 villages within this area have been analyzed for the occurrence of clines. Apparently significant clines are observed for alleles of the Rh, MNSs, Kidd, Gm, Inv and serum albumin system. Available da

19. “Private” Genetic Variants and the Frequency of Mutation Among South American Indians
Electrophoretic studies were performed on 15 proteins of blood serum and of erythrocytes, from blood specimens from 72 villages of six relatively unacculturated and genetically pure Indian tribes of South America, for a total of 56,237 determinations. At least 10 different “private” variants were encountered, in 131 people. Two previously recognized gene

20. Native American Mitochondrial DNA Analysis Indicates That the Amerind and the Nadene Populations Were Founded by Two Independent Migrations
Mitochondrial DNAs (mtDNAs) from 167 American Indians including 87 Amerind-speakers (Amerinds) and 80 Nadene-speakers (Nadene) were surveyed for sequence variation by detailed restriction analysis. All Native American mtDNAs clustered into one of four distinct lineages, defined by the restriction site variants: HincII site loss at np 13,259, AluI site loss a

21. Estimation of expected number of rare alleles of a locus and calculation of mutation rate
An approach is described for the estimation of the number of rare variants in the population from the number in a sample drawn at random from the population. This quantity is used to derive an estimate of the mutation rate. The data required are the number of rare variants in the sample and the distribution of offspring within a population of well-defined si

22. Cytogenetic "rogue" cells: what is their frequency, origin, and evolutionary significance?
Among 102,170 cultured lymphocytes obtained from 9818 individuals from Hiroshima, Japan, aged 9 to 37 years and scored for chromosomal abnormalities, 24 cells that exhibited an extreme degree of damage were encountered. The damage consists of multiple dicentric and even tricentric chromosomes, as well as numerous fragments, many with the appearance of "doubl

23. Linkage Analysis of Albuminuria
American Indians have a higher prevalence of albuminuria than the general population, likely resulting from a combination of environmental and genetic risk factors. To localize gene regions influencing variation in urinary albumin-to-creatinine ratio, we performed a linkage analysis and explored gene-by-diabetes, -hypertension, and -obesity interactions in a

24. The JC and BK human polyoma viruses appear to be recent introductions to some South American Indian tribes: There is no serological evidence of cross-reactivity with the simian polyoma virus SV40
In an effort to understand the unusual cytogenetic damage earlier encountered in the Yanomama Indians, plasma samples from 425 Amerindians representing 14 tribes have been tested for hemagglutination inhibition antibodies to the human JC polyoma virus and from 369 Amerinds from 13 tribes for hemagglutination inhibition antibodies to the human BK polyoma viru
