abaixo os resumos dos trabalhos a apresentados.
44º Congresso da Human
Biology Association Prehistoric Oral Health in
the Volta Grande of the Xingu River, State of Pará, Amazônia, Brazil

Prehistoric horticulturalist groups, in general,
have a high frequency of cavities, tartar and dental loss in life due to their
high carbohydrate diet. In this research, 26 permanent teeth of seven
individuals recovered in four archeological sites of prehistoric populations of
the Volta Grande region of the Xingu River (UHE Belo Monte Project, PA) were
analyzed, of which 19 were molars or premolars. The poor preservation of bone
parts and teeth in archeological context of tropical forest is well known.
However, as there is a dearth of information regarding the ancient peoples
inhabiting the Central Amazonia, any data may be useful to help investigate the
health of these groups. In general, the teeth sampled are fragmented or
represented by a thin layer of enamel still in the shape of the tooth only as a
result of the soil that keeps it static; and no tooth was found integral from
the crown to the root. The analysis shows a low prevalence of caries, only in
five teeth of three individuals, with higher occurrence on premolars. Tartar
was present in four teeth of a single individual, and moderate wear of the
occlusal surfaces was seen in eight premolars and molars of three individuals.
Unfortunately, the estimation of age and sex was impaired by the lack of
preservation of the bone parts. Nevertheless, from these teeth it can be
inferred that all individuals were more than 12 years old, and that they
generally enjoyed good oral health.
Riverine Women from the
Mamirauá Sustainable Development Reserve (MSDR), Tefé, Amazonas, Brazil:
Nutritional Satus and Social Determinants of Health
Filgueiras,
LA; Silva, HP; Ramos, EMLS; Moura, EAF
It has been recognized that Amazonian rural
populations are under considerable socio-ecological stress, and the percentage
of individuals with nutritional problems is high. Here we analyzed the
nutritional status and Social Determinants of Health of women from the Mamirauá
Sustainable Development Reserve (MSDR), Amazonas State, Brazil, to evaluate
their health situation. Anthropometric measurements and interviews were carried
out between 2008 and 2010 in 82 women aged 18 to 58 years. Their subsistence is
based on fishing, extraction of forest products, agriculture and, more
recently, retirements, cash transfer governmental programs (Bolsa Família), and
jobs at the MSDR and in Tefé. There is no sewage system in the communities, and
the majority houses do not have inner toilets. Water is collected directly from
river or wells. They use mostly folk medicine to take care of the family as
access to health services is limited. Average height, weight, BMI and waist
circumference were 152.21cm, 61.93kg, 26.73, and 84.5cm, respectively. 31.7%
were overweight and 26.8% obese according to the WHO cut-off points, indicating
they are at higher health risk for chronic diseases. Although there have been
improvements in the population's quality of life in the last decade, there are
still a large number of women without access to health care. In general, the
nutritional situation of MSDR residents resembles that of other rural areas of
the Amazon where populations are also socioecologically vulnerable. It is
expected that these results will contribute to the development of more
effective public health policies for these groups.
Sickle Cell Disease and the
Relationships of Race/color Self-declaration and Genomic Ancestry in the
Brazilian Amazon
AK Silva; HP Silva
In the State of Pará, Brazil, Sickle Cell Disease
(SCD) occurs in approximately 1% of the population, being a serious public
health problem. Research relating genetic ancestry (GA) data with race/color
self-declaration of people with SCA is still rare in Brazil. We analyzed 60
patients of both sexes, between 11 and 46 years of age, which were treated at
the reference center for hematologic diseases in the State using a mix of
semi-structured interviews about socioecologic conditions, self-declaration of
race/color, clinical data, and autosomal GA test to investigate the possible
interrelations among these variables. The self-declaration used the standard
Brazilian census classification, and GA tests were performed using 61 Ancestry
Information Markers (AIMs). Ancestry was estimated by Structure v.2.3.3 software,
with three parental populations (European, African and Amerindian). The results
showed that 41% of the group presented mostly European ancestry; 30.25% mostly
Amerindian, and 28.2% mostly African. Among people with predominantly European
GA, only 12% self-declarations were similar to the AIMs. The group with
Amerindian composition had 77% similarity between GA/Self-declaration. The
individuals with higher African GA reached 91% of agreement between
GA/Self-declaration. As SCD is classically considered a disease of the Black
population, DNA analysis and self-classification of race/color can be useful
health information when considering the ethnic/genetic diversity of the
Brazilian population. The majority of the participants (90%) self-declared as
black or brown, but most of their GA was European, which expresses the complex
relationships between genetic data and socio-historical events in the Brazilian
Amazon.
88º Encontro da American
Association of Physical Anthropologists - AAPA 2019 - Biological Anthropology of
Brazilian Populations – past and present.
Silva, H.P.
In Brazil, Physical Anthropology has been a
recognized field of studies since the end of the 19th Century. Nevertheless,
starting in the 1950`s until the early 1990`s, this field almost disappeared
from academic institutions, even though some individual researchers continued
to work with themes related. As a holistic and dynamic field, throughout its
history, Biological Anthropology has proven its importance. Nevertheless, until
2010 there was no formal training, whether at the undergraduate or graduate level,
in Physical/Biological Anthropology in the country. In 2010 the Graduate
Program in Anthropology of the Universidade Federal do Pará (PPGA/UFPA) was
inaugurated as the first training program involving the four traditional
fields: Archeology, Bioanthropology, Linguistics and Sociocultural
Anthropology, becoming the only one in the nation to offer training at the
Master’s and Doctoral levels specifically in Biological Anthropology. This
initiative helped to increase the creation of joint Anthropology and Archeology
programs throughout the country, and the expectation that, as the number of
Biological Anthropology graduates increase, there will be other programs
created in the Four Fields, Boasian, model. Faculty from PPGA has engaged in
transdisciplinary research, some of it in partnership with colleagues from USA
and other countries, in a broad spectrum of themes. The program is helping to
forge a new generation of anthropologists, able to investigate issues from
pre-historic to contemporary populations, demonstrating that the field can have
an important role in the comprehension of the distinct problems faced by the
Brazilian society, from its past to the present.
Relationships among
molecular markers, blood biochemistry, and anthropometry in Amazonian
Native American populations.
Diniz,
I.G.; Silva, H.P. ; Guerreiro, J.F.
The epidemiological and
nutritional transition among Native Americans is developing fast in Latin
America, which partly explain the emergence of chronic noncommunicable
diseases, specially obesity. Nevertheless, obesity is a multifactorial disease
and presents very complex inheritance patterns where the cumulative
contribution of diverse genes results in a greater or smaller individual
susceptibility to certain environmental factors. In this sense, we sought to
investigate the relation of Body Mass Index (BMI), cholesterol, glucose and
triglycerides with three single nucleotide polymorphisms - SNPs (ABCA1 rs9282541; ADRB3 rs4994;
and PPARG rs1801282) known in the literature as associated
with obesity in populations around the world. A total of 590 adult individuals
(51.86% female, mean age 39.44), living in 11 indigenous villages in the State
of Pará participated in the study. The overall mean BMI and blood biochemistry
among these populations were within normal limits. However, when groups were
considered separately, the highest overweight frequency (BMI ≥25) found was
72.7% in one given population. We found association of BMI with the SNPs of
the ABCA1and ADRB3 genes. In addition, marginal
association was found with the SNP of the PPARG gene (p =
0.06). All polymorphisms were tested for relative risk (odds ratio). The mutant
alleles of the ADRB3 and PPARG genes had an
odds ratio of 1.37 and 1.47, respectively. In contrast, the mutant allele
of ABCA1 presented a lower relative risk than the wild-type
allele (0.48) suggesting a protection against obesity to the carriers of this
Native American peoples’ exclusive variant.

Infant Condition and the
Timing of Deciduous Tooth Emergence in the Brazilian Amazon
J.E. Spence, D. Guatelli-Steinberg, B.A. Piperata,
B. Floyd, H.P. Silva.
Although highly heritable, deciduous tooth
emergence timing is not impervious to environmental influence. Studies
investigating the contribution of environmental factors to emergence timing are
inconsistent, in part because gestation length is not always considered.
Drawing on longitudinal data from 100 mother-infant dyads in a semi-urban town
in the eastern Amazon Basin, and using reliable methods to consider gestational
age, we tested three hypotheses: 1) there will be no sex difference in
emergence timing; 2) infant size for gestational age (SGA) will be inversely
correlated with first-tooth emergence age; 3) infant postnatal growth rate will
be inversely correlated with first-tooth emergence age. We implemented survival
analysis because the outcome variable was censored within similar but unequal
intervals and the Weibull model because the conditional probability of tooth
emergence increases with time. Contrary to previous studies, we found that the
first tooth was 60% more likely to emerge earlier in females (P =
0.026). There was a significant association between SGA and emergence timing of
the first tooth (P = 0.007), with an increase in SGA category
(small, appropriate, large) increasing the likelihood of emergence by 106%.
Gains in infant length, weight, and head circumference were significant
predictors of age at first-tooth emergence (P ≤ 0.004), with the
likelihood of emergence increasing from 10–170% per unit gain. Our findings
confirm that environmental factors play a significant role in the variation of
deciduous tooth emergence timing and demonstrate that emergence is susceptible
to influence at various stages of development.

Chronic Diseases in
Amazonian Populations: socioepidemiology and biocultural perspectives.
Silva,
A.K.L.S.; Filgueiras, L.; Tavares, R.B.; Silva, H.P.
In Brazil, the African-derived groups have been
historically discriminated. Even though there is a National Policy for the
Health of the Black Population (PNSIPN) there is still a dearth of actions for
its implementation. Especially among the Quilombola populations, hypertension,
type 2 diabetes and Sickle Cell Disease (SCD) are not adequately identified.
This work analyzes the links between socioepidemiologic and biocultural aspects
of these rural afroderived groups and the main challenges faced in their search
for health. Data comes from projects conducted between 2008 and 2016 with the
participation of over 2500 people, of 24 Quilombola communities, and 60 SCD
patients from Pará State. In general the most prevalent diseases among children
are related to the respiratory and digestive tracts, dermatitis and dermatosis.
In relation to the weight patterns there is a simultaneous occurrence of
undernourished (up to 4%) and overweight (up to 10%) in 0 to 10 years old
children, and the women present a high prevalence of overweight and obesity
(21%). Men present a high frequency of hypertension (18%). Among the patients,
65% live in poverty, in periurban and urban areas, 83% consider themselves
"Black" or "Brown", and the majority indicates having
suffered some form of discrimination throughout their lives. In general, the
harsh conditions of life, low economic status, environmental situation and
social vulnerability of the rural Amazonian populations have strong impacts on
their well-being. The work of biological anthropologists in Brazil is
fundamental to help empower the Black populations in their struggle for health
rights.
Oral Health in a Rural
Population of the Brazilian Amazon: implications for interpretation of dental
caries in the past.
Da-Gloria,
P.; Piperata, B.A.;Hoffman, C.; Simionato, M.R., Oliveira, R.E.; Nogueira, F.N.
Dental caries is a pathological condition caused by
the fermentation of carbohydrates by oral bacteria. Traditional interpretation
of past caries frequencies considers dietary habits as the main cause of this
pathology, as exemplified by the association between increased caries
prevalence with the transition to agriculture. Other authors suggest that human
biology, such as hormones, immune function, pregnancy, and genetic background,
should be also considered when interpreting the prevalence of caries in past
populations. In this study, we aim to test the relative importance of diet and
human biology in predicting caries rates in relatively isolated, rural
Amazonian communities located along the Middle Solimões River, Brazil. This
population still practices slash and burn agriculture, fishing, hunting, and
collecting, with industrialized foods making only moderate contributions to
their diet. In addition, the population has limited access to dental and
medical services and a relatively high fertility rate. We collected data on
saliva flux, dietary habits, oral pathologies, oral hygiene, and reproductive
histories of 107 riverine people (39 men and 68 women; average age of 27
years). We ran a multiple linear regression using decayed, missing, and filled
teeth as a dependent variable. Our model explained 20.7% of the variation and
found age and stimulated saliva flux as the main predictors of caries
prevalence. Although this is a preliminary model, we can highlight the
importance of saliva flux as a protector against caries, emphasizing a
multifactorial interpretation of caries disease.

Resilience of the
hunter-gatherers of Lagoa Santa, Brazil: A new case of Paleoamerican late
survival.
Vicensotto
Bernardo, D.; Da-Gloria, P.; Neves, W.A.
The contributions of Biological Anthropology are
crucial to understanding the occupation of the New World, allowing the
proposition of models discussing origin, dispersion, and chronologies of Native
Americans. In this context, the investigation of long-term occupations can shed
light on the processes of resilience, territorial strategies, and biocultural
adaptation of the Native Americans. Here we present a new case of Paleoamerican
late survival in South America, based on a new radiocarbon date and the
morphology of Lapa do Caetano's skull exhumed in the beginning of the 20th
century at Lagoa Santa, Central-Eastern Brazil. We applied multivariate
statistical techniques on craniometric measurements in accordance with Howells'
protocol followed by tests for the best dispersion scenarios to evaluate the
likelihood of the late survival of Paleoamerican morphology. Our results show
that Lapa do Caetano' skull is dated to 2120 +/- 30 BP (BETA 396821) and
retained the same Paleoamerican morphological pattern found in early skulls in
the Americas and in recent crania found in Central-Eastern Brazil. The archaeological
data show intermittent hunter-gatherer occupations in the region retaining the
same basic strategies of subsistence. These results suggest strong resilience
of these South American hunter-gatherers in both cultural and biological
aspects, which have important implications for the models of peopling of the
New World. As in previous studies, our investigation shows that models which
consider a late survival of the Paleoamerican morphology are better adjusted
compared with the models that propose a complete substitution of this early
morphology.
