A reunião de africanos, escravos e libertos, em grupos étnicos foi uma das características das formas de organização e de sociabilidades dessa população em várias regiões do Brasil. A princípio, essas categorias étnicas foram criadas pelos indivíduos que lidavam com o comércio de escravos, quais sejam, traficantes, comerciantes e compradores, carregando consigo atributos físicos, morais e características culturais que tinham como objetivo facilitar o tráfico. Mais tarde, essa distinção étnica também foi incorporada pelos próprios africanos, escravos e libertos, como um elemento da sua própria organização. Esta dissertação tem por objetivo estudar o processo de redefinição dos grupos étnicos e a construção das identidades africanas em torno de alguns espaços de sociabilidade na cidade de São Paulo, durante a primeira metade do século XIX. Pretende-se discutir, baseando-se no conceito de grupo étnico elaborado pelo antropólogo Fredrik Barth, as formas de atribuição e de identificação desses grupos por agentes externos, como a Igreja Católica e os proprietários de escravos. Esse conceito também tem como pressuposto a incorporação pelos próprios africanos, que passaram a se identificar com esses grupos éticos...

Paraoxonase (PON) é uma família multigene de enzimas, a qual inclui PON1, PON2 e PON3. Investigações há mais de duas décadas vêm permitindo um melhor conhecimento da função dos genes da paraoxonase, em especial da PON1, no metabolismo de inseticidas organofosforados, lípides oxidados e medicamentos. O principal local de síntese da PON1 é o fígado, e no soro encontra-se mais comumentente associada à HDL-C. Exibe dois principais polimorfismos, posição 55 (L/M) e 192 (Q/R) que estão relacionados ao nível sérico e atividade enzimática respectivamente. A freqüência dos alelos do gene PON1 apresenta considerável variabilidade entre diferentes populações. São escassos os estudos sobre a PON2, porém sabe-se que é expressa em vários tecidos, sugerindo, dessa forma, que essa enzima tenha uma ação localizada (intracelular). Dois polimorfismos são os mais estudados no gene PON2, posições 148 (A/G) e 311 (C/S) e têm sido associados à numerosas condições fisiopatológicas como variações no metabolismo e níveis plasmáticos de lipoproteínas e glicose. Este trabalho tem por objetivos caracterizar as freqüências das mutações 192 (Q/R) e 55(L/M) no gene da PON1 e 311(C/S) e 148(A/G) no gene da PON2, bem como analisar a atividade das isoformas da enzima PON1 em uma população brasileira...

Dissertação de Mestrado em Psicologia Educacional; Esta investigação de carácter quantitativo-correlacional pretende analisar a relação entre os domínios da identidade étnica e a auto-estima, e entre esta última variável e a discriminação étnica percepcionada; analisam-se também as associações entre a exploração e a discriminação étnica percepcionada perpetrada pelos pares; e averiguam-se ainda as relações entre os domínios da identidade étnica e a orientação para os out-groups no grupo das etnias minoritárias. Estas relações são analisadas em 387 adolescentes de diferentes grupos étnicos, com uma média de idades de 13.75. Os dados foram recolhidos utilizando a Escala de Autoconceito e Auto-estima de Peixoto e Almeida (1999; Peixoto, 2003), a Escala de Identidade Étnica (Umaña-Taylor, Yazedjian, Bámaca-Gomez, 2004), e a Escala de Discriminação Étnica Percepcionada, construída para avaliar as percepções de discriminação étnica. Os resultados mostram diferenças significativas nos níveis de identidade étnica global e na exploração, entre o grupo da etnia Portuguesa e o grupo das etnias minoritárias. Observaram-se correlações significativas e positivas entre a auto-estima e a exploração...

We conducted a case-control study of the association between SIL and HPV among whites (W), African Americans (AA), and Hispanics (H) in Harris County, Texas. Cases were identified at M.D. Anderson Cancer Center Colposcopy Clinic. Controls were identified among women obtaining routine Pap screening at two Harris County Health Department Clinics. HPV was detected by a PCR-based fluorescent assay. Dichotomous and polytomous logistic regression models were used to estimate adjusted odd ratios (AOR) and 95% confidence intervals (CI) for SIL among racial/ethnic groups and grade of disease. Prevalence of HPV infection was 64% in low grade SIL (LSIL), 84% in high grade SIL (HSIL), and 19% in controls. Risk of SIL was higher in H than in W and AA, AOR 29.5 (12.4-70.5), 15.3 (6.0-33.8), and 5.8 (2.6-12.6), respectively. Similarly, racial/ethnic differences were observed for both LSIL (AOR = 16.6, 7.7, and 4.3, respectively) and HSIL (AOR = 78.6, 34.6, and 14.2, respectively). Findings support the association between SIL and HPV and differences in the strength of the association with LSILs and HSILs. Data also suggest a higher risk for H and a lower risk for AA.

Background: Whereas it is well established that plasma lipid levels have substantial heritability within populations, it remains unclear how many of the genetic determinants reported in previous studies (largely performed in European American cohorts) are relevant in different ethnicities. Methodology/Principal Findings: We tested a set of (sim)50,000 polymorphisms from (sim)2,000 candidate genes and genetic loci from genome-wide association studies (GWAS) for association with low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) in 25,000 European Americans and 9,000 African Americans in the National Heart, Lung, and Blood Institute (NHLBI) Candidate Gene Association Resource (CARe). We replicated associations for a number of genes in one or both ethnicities and identified a novel lipid-associated variant in a locus harboring ICAM1. We compared the architecture of genetic loci associated with lipids in both African Americans and European Americans and found that the same genes were relevant across ethnic groups but the specific associated variants at each gene often differed. Conclusions/Significance: We identify or provide further evidence for a number of genetic determinants of plasma lipid levels through population association studies. In many loci the determinants appear to differ substantially between African Americans and European Americans.

Latin American countries are generally characterized as displaying high income and earnings inequality overall along with high inequality by gender, race, and ethnicity. However, the latter phenomenon is not a major contributor to the former phenomenon. Using household survey data from four Latin American countries (Bolivia, Brazil, Guatemala, and Guyana) for which stratification by race or ethnicity is possible, this paper demonstrates (using Theil index decompositions as well as Gini indices, and 90/10 and 50/10 percentile comparisons) that within-group earnings inequality rather than between-group earnings inequality is the main contributor to overall earnings inequality. Simulations in which the relatively disadvantaged gender and/or racial/ethnic group is treated as if it were the relatively advantaged group tend to reduce overall earnings inequality measures only slightly and in some cases have the effect of increasing earnings inequality measures.

Background: In the United Kingdom, there has been an increase in cigarette smoking in ethnic minority adults since the 1970s; in some groups levels are now similar to that of White British people. We aimed to examine the determinants of exposure to secondhand smoke in ethnic minority children. We hypothesised that exposure to secondhand smoke in children will vary across ethnic groups, but that the correlates of exposure would be similar to that of Whites. Methods: The Determinants of Adolescent Social well-being and Health sample comprises 3468 White United Kingdom and ethnic minority (Black Caribbean, Black African, Indian, Pakistani, Bangladeshi) pupils aged 11-13 yrs. Outcome was saliva cotinine concentration. Explanatory variables collected by self-complete questionnaire included ethnicity, child reported household smoking and socio-economic circumstances. Data were analysed using linear regression models with a random intercept function. Results: Ethnic minority children had lower saliva cotinine than Whites, partly explained by less smoking among parents. White and Black Caribbean children had higher cotinine levels if they lived in a household with a maternal smoker only, than with a paternal smoker only. Living in a lone compared to a dual parent household was associated with increased cotinine concentration of 45% (95%CI 5...

BACKGROUND: Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer death among women in the United States and varies systematically by race-ethnicity and socioeconomic status. Previous research has often focused on disparities between particular groups, but few studies have summarized disparities across multiple subgroups defined by race-ethnic and socioeconomic position. METHODS: Data on breast cancer incidence, stage, mortality, and 5-year cause-specific probability of death (100 - survival) were obtained from the Surveillance, Epidemiology, and End Results program and data on mammography screening from the National Health Interview Survey from 1987 to 2005. We used four area-socioeconomic groups based on the percentage of poverty in the county of residence (<10, 10-15, 15-20, +20%) and five race-ethnic groups (White, Black, Asian, American Indian, and Hispanic). We used summary measures of disparity based on both rate differences and rate ratios. RESULTS: From 1987 to 2004, area-socioeconomic disparities declined by 20% to 30% for incidence, stage at diagnosis, and 5-year cause-specific probability of death, and by roughly 100% for mortality, whether measured on the absolute or relative scale. In contrast...

The cornea is a transparent structure that permits the refraction of light into the eye. Evidence from a range of studies indicates that central corneal thickness (CCT) is strongly genetically determined. Support for a genetic component comes from data showing significant variation in CCT between different human ethnic groups. Interestingly, these studies also appear to show that skin pigmentation may influence CCT. To validate these observations, we undertook the first analysis of CCT in an oculocutaneous albinism (OCA) and Ugandan cohort, populations with distinct skin pigmentation phenotypes. There was a significant difference in the mean CCT of the OCA, Ugandan and Australian-Caucasian cohorts (Ugandan: 517.3±37 µm; Caucasian: 539.7±32.8 µm, OCA: 563.3±37.2 µm; p<0.001). A meta-analysis of 53 studies investigating the CCT of different ethnic groups was then performed and demonstrated that darker skin pigmentation is associated with a thinner CCT (p<0.001). To further verify these observations, we measured CCT in 13 different inbred mouse strains and found a significant difference between the albino and pigmented strains (p = 0.008). Specific mutations within the melanin synthesis pathway were then investigated in mice for an association with CCT. Significant differences between mutant and wild type strains were seen with the nonagouti (p<0.001)...

Telecounselling – the provision of counselling services by telephone, videoconferencing or Internet media – can assist with disparities in the treatment and management of depression for minority ethnic groups. We therefore reviewed the evidence examining the effectiveness of telecounselling for this population. This involved a search of electronic databases, the grey literature and two peer-reviewed journals. Study quality was examined using the Oxford Centre for Evidence Based Medicine guidelines. Cohen’s d effect sizes were additionally calculated for between-study comparisons. The final sample comprised eight independent studies, with a total of 498 adults of Asian, African-American or Spanish origin. None of the studies met the criteria for the highest methodological rating (Level 1) and there were five studies at Level 2. Significant short-term treatment effects were associated with telephone- and Internet-mediated services, including moderate to large improvements across measures of depression, anxiety, quality of life and psychosocial functioning reported. Longer-term treatment effects were also reported, although these results were based on very limited data. The results highlight the need for additional rigorous research to determine the clinical efficacy of telecounselling as a treatment option for depression among minority communities.; Diana S Dorstyn...

Afghanistan has held a strategic position throughout history. It has been inhabited since the Paleolithic and later became a crossroad for expanding civilizations and empires. Afghanistan's location, history, and diverse ethnic groups present a unique opportunity to explore how nations and ethnic groups emerged, and how major cultural evolutions and technological developments in human history have influenced modern population structures. In this study we have analyzed, for the first time, the four major ethnic groups in present-day Afghanistan: Hazara, Pashtun, Tajik, and Uzbek, using 52 binary markers and 19 short tandem repeats on the non-recombinant segment of the Y-chromosome. A total of 204 Afghan samples were investigated along with more than 8,500 samples from surrounding populations important to Afghanistan's history through migrations and conquests, including Iranians, Greeks, Indians, Middle Easterners, East Europeans, and East Asians. Our results suggest that all current Afghans largely share a heritage derived from a common unstructured ancestral population that could have emerged during the Neolithic revolution and the formation of the first farming communities. Our results also indicate that inter-Afghan differentiation started during the Bronze Age...

This report examines the significance of ethnic representation in local, state and federal Australian governments and the role multiculturalism has played in effecting political participation. In exploring this relationship, four areas are considered: the history and policies of multiculturalism, the structural and cultural barriers to representation, the experience of local councils and the relevance of Non English Speaking Background (NESB) politicians in federal parliament. Multiculturalism was formally recognised by the Galbally Report commissioned by the Fraser government in 1978. As a concept, multiculturalism envisaged a more balanced approach to migrant integration, acknowledging Australia's presence as an immigrant nation. Since the 1980s successive Australian Labor Party (ALP) and Coalition governments have struggled to define multiculturalism's role within an Australian identity. The Coalition's transition to a more inclusive model of citizenship and values is reflective of the changing attitudes towards multiculturalism. Prime Minister Howard's characterisation of a unified Australia is a response to perceived public sentiment that frequently overlooks the relevance of non-Anglo Celtic cultures. In contrast state governments have taken a more equitable approach to people from culturally diverse backgrounds in public life as demonstrated by the ethnically diverse parliaments of New South Wales and Victoria. Unfortunately...

The present paper “Study on cultural pattern and human migration along the Chinese Silk Road (Gansu-Qinghai stretch): taking the Salar’s ethnic formation and development as an example” has a rather simple framework which unceasingly oscillates between structural analysis and historical narration. Starting from a cross-cultural perspective, it combines traditional historical insights and postmodern paradigms of conceiving history. It consists on three parts - concept definition, historical analysis and critical inquiries, fieldwork summarization - presenting a comprehensive research on the topic. Through a combination of various theoretical approaches and practical historical examples, it pays attention to the formation and development of ethnic patterns under the influence of human migrations, and describes above all the heterogeneity, variability, and diversity of Gansu-Qinghai regional culture and of its constituent ethnic cultures. It investigates, respectively, their inner structures, their historical transformations, and the forging and maintenance of specific boundaries dividing the ethnic groups involved, thus refuting by placing them under the category of “ethnic isle” or “ideal cultural type”. Ethnic groups that inhabit exclusively in the Gansu-Qinghai region (most commonly known as "ganqing diqu" in Chinese) are raised here as an example. They represent the central subject matter of the paper. The entire framework of the first part is dedicated to the discussion of this idea and provides a solid support for the following observations.

The thesis assesses the impact of international factors on relations between Greek and Turkish Cypriots during and after the Cold War. Through an analysis of the Cyprus problem it explores both why external actors intervene in communal conflicts and how they influence relations between ethnic groups in plural societies. The analytical framework employed throughout the study draws on contributions of International Relations theorists and students of ethnic conflict. The thesis argues that, as in the global political system, relations between ethnic groups in unranked communal systems are anarchic; that is, actors within the system do not recognize a sovereign political authority. In bipolar communal systems dominated by two relatively equal groups, the struggle for security and power often leads to appeals for assistance from external actors. The framework notes that neighboring states and Great Powers may heed calls for assistance, or intervene without a prior request, if it is in their interest to do so. The convergence of regional and global interests in communal affairs exacerbates ethnic conflicts and precludes the development of effective political institutions. The impact of external intervention in ethnic conflicts has the potential to alter the basis of communal relations. The Cyprus problem is examined both during and after the Cold War in order to gauge how global and regional actors and the structure of their respective systems have affected relations between ethnic groups in Cyprus. The thesis argues that Cyprus's descent into civil war in 1963 was due in part to the entrenchment of external interests in the Republic's constitution. The study also notes that power politics involving the United States...

Weight gain achieved during pulmonary tuberculosis (PTB) treatment is associated with the likelihood of bacteriological treatment success. It is recognised that weight and body mass index (BMI) characteristics differ between ethnic groups in health and illness states. However there has been no prior investigation of how ethnic differences in BMI might influence tuberculosis treatment outcome. Our aim was to investigate predictors of microbiological response to PTB treatment at the Tuberculosis Clinic in Timika, Papua Province, Indonesia and specifically, to determine the contribution of ethnicity. The population comprises two distinct ethnic groups - Asian (Non-Papuan) and Melanesian (Papuan). We conducted a prospective study of adults with smear-positive PTB. Treatment outcomes were 1- and 2-month sputum culture and time to microscopy conversion. Clinical measures included weight, BMI, chest radiograph, pulmonary function including forced expiratory volume in 1 second (FEV1) and haemoglobin. One hundred eighty six participants (83 Papuan, 103 non-Papuan Indonesians) were enrolled. At baseline, Papuans had higher mean weight and BMI than non-Papuans (50.0 kg versus 46.9 kg, p = 0.006 and 20.0 kg/m2 versus 18.7 kg/m2, p = 0.001 respectively). This was despite having lower mean haemoglobin (11.3 vs 13.1 g/dL...

We studied concerns about cognitive health among ethnically diverse groups of older adults. The study was grounded in theories of health behaviour and the representation of health and illness. We conducted 42 focus groups (N=396, ages 50+) in four languages, with African Americans, American Indians, Chinese Americans, Latinos, Whites other than Latinos (hereafter, Whites) and Vietnamese Americans, in nine United States locations. Participants discussed concerns about keeping their memory or ability to think as they age. Audio recordings were transcribed verbatim. Constant comparison methods identified themes. In findings, all ethnic groups expressed concern and fear about memory loss, losing independence, and becoming ‘a burden’. Knowing someone with Alzheimer's disease increased concern. American Indians, Chinese Americans, Latinos and Vietnamese Americans expected memory loss. American Indians, Chinese Americans and Vietnamese Americans were concerned about stigma associated with Alzheimer's disease. Only African Americans, Chinese and Whites expressed concern about genetic risks. Only African Americans and Whites expressed concern about behaviour changes. Although we asked participants for their thoughts about their ability to think as they age...

The sample was composed of 1428 students (696 males and 732 females). The descriptive statistical methods ANOVA, the Tukey test (p≤ 0.05) and the chi-square test (χ2) were used to analyze the data. Differences were observed in the heights of girls aged up to 9 years, with the Polish group being shorter, and, up to 15 years, for both the Polish and German groups, when compared with the group of Italians. In terms of body mass, there were differences up to 14 years (males) and up to 9 years (females), with the Polish schoolchildren having lowest mass. The German schoolchildren had the highest body fat percentage at 12 years (males) while at 15 years (females), the Polish children had higher body fat percentage than the other ethnic groups (p≤ 0.05). The Polish children exhibited inferior lean body mass (p≤ 0.05) at 14 years (males) and at 9 years (females). The prevalence rates of obesity, for males and females respectively, were 11.1% and 16.2% among the German schoolchildren...

Findings support the association between SIL and HPV and differences in the strength of the association with LSILs and HSILs. Data also suggest a higher risk for H and a lower risk for AA.
