Full Text Available Rural and minority women are disproportionately impacted by the obesity epidemic; however, little research has studied the intersection of these disparity groups. The purpose of this study was to examine the influence of racial identity on motivation for weight loss and exercise among rural, African-American women with an obesity-linked chronic disease. A total of 154 African-American women were recruited from the patient population of a Federally Qualified Health Center in the rural South to complete a questionnaire battery including the Multigroup Ethnic Identity Measure and separate assessments of motivation for weight loss and exercise. Multivariate analyses, controlling for age, education status, insurance status, and body mass index revealed that attachment to ethnic identity was predictive of motivation for exercise but not for weight loss. Our findings suggest that attachment to ethnic identity may be an important factor in motivation for change among African-American women, particularly with respect to exercise, with direct implications for the development of culturally and geographically tailored weight loss interventions.

Full Text Available This paper empirically tests the link between cultural orientation, market orientation, service innovation capabilities of owner-managers and the level of inward internationalisation of African-ethnic restaurants. Data were obtained from 201 African-ethnic restaurants. A twostep approach was used, i.e. (i a confirmatory factor analysis (CFA to generate a measurement model; and (ii a structural equation model (SEM to test the hypotheses. All the predictor variables are positively and significantly related to the degree of inward internationalisation and the relationship is strong enough to cause a 41 per cent variance. Since it is cross-sectional in design, the study cannot be fully relied upon to draw inferences regarding causality among the variables. The results suggest that owner-managers who develop the three capabilities succeed in enhancing inward internationalisation. The current study could be among the very few to propose a framework that brings together major managerial (dynamic capabilities that are presumed to be vital in enhancing inward internationalisation.

Background and Objective Genetic markers associated with disease are often non-functional and generally tag one or more functional “causative” variants in linkage disequilibrium. Markers may not show tight linkage to the causative variants across multiple ethnicities due to evolutionary divergence, and therefore may not be informative across different population groups. Validated markers of disease suggest causative variants exist in the gene and, if the causative variants can be identified, it is reasonable to hypothesize that such variants will be informative across diverse populations. The aim of this study was to test that hypothesis using functional Interleukin-1 (IL-1) gene variations across multiple ethnic populations to replace the non-functional markers originally associated with chronic adult periodontitis in Caucasians. Material and Methods Adult chronic periodontitis cases and controls from four ethnic groups (Caucasians, African Americans, Hispanics and Asians) were recruited in the USA, Chile and China. Genotypes of IL1B gene single nucleotide polymorphisms (SNPs), including three functional SNPs (rs16944, rs1143623, rs4848306) in the promoter and one intronic SNP (rs1143633), were determined using a single base extension method or TaqMan 5′ nuclease assay. Logistic regression and other statistical analyses were used to examine the association between moderate to severe periodontitis and IL1B gene variations, including SNPs, haplotypes and composite genotypes. Genotype patterns associated with disease in the discovery study were then evaluated in independent validation studies. Results Significant associations were identified in the discovery study, consisting of Caucasians and African Americans, between moderate to severe adult chronic periodontitis and functional variations in the IL1B gene, including a pattern of four IL1B SNPs (OR = 1.87, p < 0.0001). The association between the disease and this IL1B composite genotype pattern was validated

Full Text Available Family history and African-American race are important risk factors for both prostate cancer (CaP incidence and aggressiveness. When studying complex diseases such as CaP that have a heritable component, chances of finding true disease susceptibility alleles can be increased by accounting for genetic ancestry within the population investigated. Race, ethnicity and ancestry were studied in a geographically diverse cohort of men with newly diagnosed CaP.Individual ancestry (IA was estimated in the population-based North Carolina and Louisiana Prostate Cancer Project (PCaP, a cohort of 2,106 incident CaP cases (2063 with complete ethnicity information comprising roughly equal numbers of research subjects reporting as Black/African American (AA or European American/Caucasian/Caucasian American/White (EA from North Carolina or Louisiana. Mean genome wide individual ancestry estimates of percent African, European and Asian were obtained and tested for differences by state and ethnicity (Cajun and/or Creole and Hispanic/Latino using multivariate analysis of variance models. Principal components (PC were compared to assess differences in genetic composition by self-reported race and ethnicity between and within states.Mean individual ancestries differed by state for self-reporting AA (p = 0.03 and EA (p = 0.001. This geographic difference attenuated for AAs who answered "no" to all ethnicity membership questions (non-ethnic research subjects; p = 0.78 but not EA research subjects, p = 0.002. Mean ancestry estimates of self-identified AA Louisiana research subjects for each ethnic group; Cajun only, Creole only and both Cajun and Creole differed significantly from self-identified non-ethnic AA Louisiana research subjects. These ethnicity differences were not seen in those who self-identified as EA.Mean IA differed by race between states, elucidating a potential contributing factor to these differences in AA research participants: self-reported ethnicity

Racial/ethnic socialization has not been studied in the context of other parenting behaviors such as parental involvement in education and its relationship to children's cognitive outcomes. The present study tested the impact of racial/ethnic socialization and parental involvement in education on cognitive ability and achievement in a sample of African American youth. Two dimensions of racial/ethnic socialization, cultural exposure (i.e., exposure to diverse cultures) and cultural socialization (i.e., in-group pride), were examined in a sample of 92 African American mother-child dyads, of which 50% were female. Maternal reports of involvement during their child's 5th grade year were examined as a moderator in the relationship between racial/ethnic socialization and cognitive ability and achievement. Hierarchical regression analyses revealed that mothers' reports of cultural exposure messages measured in 4th grade predicted children's scores on 5th grade assessments of passage comprehension. There was also a significant interaction indicating that greater cultural exposure and more parental involvement in education predicted better reading passage comprehension scores over time. The implications for assessing dimensions relevant to cognitive ability and achievement in African American children are discussed.

2013-01-01

The historical image of the Black Jezebel - a hypersexual, seductive and manipulative slave woman - has been one of the most pervasive and evolving images influencing the sexual socialization and perceptions of African American women today. This preliminary study examined generational differences in the endorsement of modern depictions of the Jezebel, as well as the relationship between racial-ethnic esteem and endorsement of this sexualised image. A total of 249 African American women completed an online, self-report questionnaire assessing study variables. Results suggested that younger women (aged 18-34) may exhibit higher endorsement of the modern Jezebel depictions. Additionally, aspects of racial-ethnic esteem may be linked to lower endorsement of modern Jezebel depictions among younger and older (55 years and older) African American women. Implications for future research and clinical practice are discussed.

This study evaluated both the parenting styles and family ecologies models with interview responses from 93 14- and 15-year-old African-American adolescents. The parenting styles model was more strongly represented in both open-ended and structured interview responses. Using variables from the structured interview as independent variables, regression analyses contrasted each model with a joint model for predicting self-esteem, self-reliance, work orientation, and ethnic identity. Overall, the findings suggest that a joint model that combines elements from both models provides a richer understanding of African-American families.

Background Ethnic minorities in Europe have high susceptibility to type 2 diabetes (T2DM) and, in some groups, also cardiovascular disease (CVD). Pregnancy can be considered a stress test that predicts future morbidity patterns in women and that affects future health of the child. Objective To review ethnic differences in: 1) adiposity, hyperglycaemia, and pre-eclampsia during pregnancy; 2) future risk in the mother of obesity, T2DM and CVD; and 3) prenatal development and possible influences of maternal obesity, hyperglycaemia, and pre-eclampsia on offspring's future disease risk, as relevant for ethnic minorities in Europe of Asian and African origin. Design Literature review. Results Maternal health among ethnic minorities is still sparsely documented. Higher pre-pregnant body mass index (BMI) is found in women of African and Middle Eastern descent, and lower BMI in women from East and South Asia compared with women from the majority population. Within study populations, risk of gestational diabetes mellitus (GDM) is considerably higher in many minority groups, particularly South Asians, than in the majority population. This increased risk is apparent at lower BMI and younger ages. Women of African origin have higher risk of pre-eclampsia. A GDM pregnancy implies approximately seven-fold higher risk of T2DM than normal pregnancies, and both GDM and pre-eclampsia increase later risk of CVD. Asian neonates have lower birth weights, and mostly also African neonates. This may translate into increased risks of later obesity, T2DM, and CVD. Foetal overgrowth can promote the same conditions. Breastfeeding represents a possible strategy to reduce risk of T2DM in both the mother and the child. Conclusions Ethnic minority women in Europe with Asian and African origin and their offspring seem to be at increased risk of T2DM and CVD, both currently and in the future. Pregnancy is an important window of opportunity for short and long-term disease prevention. PMID:23467680

2008-10-01

The current study examined ethnic differences in horizontal and vertical dimensions of individualism and collectivism among 96 African American and 149 European American college students. Participants completed the 32-item Singelis et al. (1995) Individualism/Collectivism Scale. Multivariate analyses of variance results yielded a main effect for ethnicity, with African Americans being significantly higher on horizontal individualism and European Americans being higher on horizontal collectivism and vertical individualism. A moderated multiple regression analysis indicated that ethnicity significantly moderated the relationship between individualism and collectivism. Individualism and collectivism were significantly and positively associated among African Americans, but not associated among European Americans. In addition, collectivism was related to grade point average for African Americans but not for European Americans. Contrary to the prevailing view of individualism-collectivism being unipolar, orthogonal dimensions, results provide support for individualism-collectivism to be considered as unipolar, related dimensions for African Americans.

Black women have higher rates of cervical cancer and lower rates of HPV vaccination than White women in the United States, and Haitians may be an especially vulnerable subgroup of Black women. To reduce these disparities, understanding differences among subgroups of Black women is crucial. The objective of our study was to assess similarities and differences in the knowledge, attitudes, beliefs, and practices toward HPV vaccination and actual vaccination rates among African-American and Haitian immigrant women and their daughters. We used validated surveys of HPV knowledge, trust in physicians, acculturation, and constructs of the health belief model: Perceived susceptibility, severity, and barriers. We probed women's thought processes about vaccination using open-ended questions. We then reviewed medical records to determine vaccination rates. Nineteen African Americans and 51 Haitians participated. Although 75% of Haitians and 63% of African Americans intended to vaccinate their daughters, only 47% of African-American and 31% of Haitian daughters were vaccinated. African Americans were more knowledgeable than Haitians and had more prior experience with HPV disease. Most African Americans felt that vaccination fell within the parental role, whereas many Haitians felt uncomfortable vaccinating against sexually transmitted infections because they felt children should not be having sex. Both ethnic groups wanted more information about HPV vaccines. Cultural differences between African-American and Haitian immigrant mothers revealed distinct barriers for vaccine acceptance. Improving HPV vaccine rates in Black women may require culturally competent and sensitive approaches that address ethnic-specific barriers. Copyright © 2012 Jacobs Institute of Women's Health.

Media exposure has been positively correlated with body dissatisfaction. While body image concerns are common, being African American has been found to be a protective factor in the development of body dissatisfaction. Participants either viewed ten advertisements showing 1) ethnically-similar thin models; 2) ethnically-different thin models; 3) ethnically-similar plus-sized models; and 4) ethnically-diverse plus-sized models. Following exposure, body image was measured. African American women had less body dissatisfaction than Caucasian women. Ethnically-similar thin-model conditions did not elicit greater body dissatisfaction scores than ethnically-different thin or plus-sized models nor did the ethnicity of the model impact ratings of body dissatisfaction for women of either race. There were no differences among the African American women exposed to plus-sized versus thin models. Among Caucasian women exposure to plus-sized models resulted in greater body dissatisfaction than exposure to thin models. Results support existing literature that African American women experience less body dissatisfaction than Caucasian women even following exposure to an ethnically-similar thin model. Additionally, women exposed to plus-sized model conditions experienced greater body dissatisfaction than those shown thin models. Copyright © 2014 Elsevier Ltd. All rights reserved.

Purpose of the Study: Few existing studies have addressed racial/ethnic differences in the health and quality of life of lesbian, gay, bisexual, and transgender (LGBT) older adults. Guided by the Health Equity Promotion Model, this study examines health-promoting and health risk factors that contribute to racial/ethnic health disparities among LGBT adults aged 50 and older. Design and Methods: We utilized weighted survey data from Aging with Pride: National Health, Aging, and Sexuality/Gender Study. By applying multiple mediator models, we analyzed the indirect effects of race/ethnicity on health-related quality of life (HRQOL) via demographics, lifetime LGBT-related discrimination, and victimization, and socioeconomic, identity-related, spiritual, and social resources. Results: Although African Americans and Hispanics, compared with non-Hispanic Whites, reported lower physical HRQOL and comparable psychological HRQOL, indirect pathways between race/ethnicity and HRQOL were observed. African Americans and Hispanics had lower income, educational attainment, identity affirmation, and social support, which were associated with a decrease in physical and psychological HRQOL. African Americans had higher lifetime LGBT-related discrimination, which was linked to a decrease in their physical and psychological HRQOL. African Americans and Hispanics had higher spirituality, which was associated with an increase in psychological HRQOL. Implications: Findings illustrate the importance of identifying both health-promoting and health risk factors to understand ways to maximize the health potential of racially and ethnically diverse LGBT older adults. Interventions aimed at health equity should be tailored to bolster identity affirmation and social networks of LGBT older adults of color and to support strengths, including spiritual resources.

Historically marginalized groups are likely to be exposed to social adversity, which predicts important mental health outcomes (e.g., depression). Despite the well-established relationship between adversity and poor health, few studies have examined how adversity differentially predicts mental health among people living with multiple, co-occurring marginalized identities or statuses. The current study fills this gap by examining whether relationships between social adversity and depressive symptoms differed between those living with or without a stigmatized disease (i.e., HIV) and/or marginalized racial/ethnic identity (i.e., African American). A community sample of men and women (N = 149) completed questionnaires assessing demographics and depressive symptoms. Additionally, a composite index of social adversity was derived from measures of perceived discrimination, socioeconomic status, financial restriction to receiving medical care, and perceived neighborhood characteristics. Multiple regression was used to test whether relationships between adversity and depressive symptoms differed as a function of HIV status and racial/ethnic identity. A significant 3-way interaction between social adversity, HIV status, and racial/ethnic identity indicated that there was a direct relationship between adversity and depressive symptoms for HIV-positive (HIV+) African Americans but not for HIV-negative (HIV-) African Americans, HIV+ Caucasians, or HIV- Caucasians. Further, HIV+ African Americans evidenced a significantly greater relationship between adversity and depressive symptoms compared with HIV- African Americans, but not compared with other groups. The findings suggest that HIV+ African Americans may be at risk for higher depressive symptoms amid adversity, highlighting the importance of evaluating intersectional identities/statuses in the context of mental health.

Full Text Available Little attention has been given to differences in obesity risk factors by racial/ethnic groups. Using data from the 2011-2012 California Health Interview Survey, we examined differences in risk factors for obesity among Whites, Latinos, Asians, and African Americans among 42,935 adults (24.8% obese. Estimates were weighted to ensure an unbiased representation of the Californian population. Multiple logistic and linear regression analyses were used to examine the differences in risk factors for obesity. Large ethnic disparities were found in obesity prevalence: Whites (22.0%, Latinos (33.6%, African Americans (36.1%, and Asians (9.8%. Differences in risk factors for obesity were also observed: Whites (gender, age, physical activity, smoking, arthritis, and diabetes medicine intake, Latinos (age, arthritis, and diabetes medicine intake, Asians (age, binge drinking, arthritis, and diabetes medicine intake, and African Americans (gender, physical activity, smoking, binge drinking, and diabetes medicine intake. Females were more likely to be obese among African Americans (odds ratio (OR = 1.43, 95% confidence interval (CI = 1.05–1.94, but less likely among Whites (OR = 0.80, 95% CI = 0.74–0.87.

Despite the recognized need for culturally tailored HIV prevention interventions for gay, bisexual, and questioning youth, few studies have examined if predictors of unprotected sex vary for youth from different ethnic groups. This study reports on a sample of 189 gay, bisexual, and questioning youth (age 15-22) from three racial/ethnic backgrounds (African American, Hispanic, and White) recruited in Chicago, IL and Miami-Dade and Broward Counties, Florida. For African American youth, being in a long-term relationship, having been kicked out of the home for having sex with men, and younger age at initiation of sexual behavior were associated with unprotected sex. For Hispanic youth, higher ethnic identification and older age at initiation of sexual behavior were associated with unprotected sex. For White youth, no predictors were associated with unprotected sex. Our findings point to the importance of understanding the varying predictors of unprotected sex and integrating them into tailored prevention interventions.

Full Text Available In South Africa men are more likely than women to undertake entrepreneurial activity. Similarly, White South Africans are more likely to start new business ventures than other ethnic groups. In order to establish why women and certain ethnic groups are less inclined to undertake entrepreneurial activities, the primary objective of this study was to establish whether the perceptions of desirability that some groups have of an entrepreneurial career differ from those of others. Respondents were identified by means of convenience and judgemental sampling. In total, 739 usable questionnaires were returned. The validity and reliability of the measuring instrument was assessed by means of an exploratory factor analysis and Cronbach-alpha coefficients. T-test statistics were undertaken to establish significant differences. The results show that female small business owners perceive that self-employment will allow them more Flexibility and Autonomy than do their male counterparts, whereas male students perceive that self-employment will allow them more Time than do female students. Black small business owners and Black student respondents scored higher mean scores than White respondents for the majority of work values investigated in this study. This seems to suggest that Black respondents perceive an entrepreneurial career more positively than White respondents do, despite White South Africans being more likely to start entrepreneurial ventures than Black South Africans.

Racial/ethnic disparities in mental disorders, including pathological gambling disorder (PGD), may be either real or artifacts of how they are conceptualized and measured. We aimed to assess racial/ethnic variation in the reliability of self-reported lifetime PGD determined by meeting > or = 5 criteria of the Diagnostic and Statistical Manual of Mental Disorders. Using community advertising, we recruited 15-85-year-old Caucasians (n = 225) and African (American/other minorities (n = 87), who had gambled more than 5 times lifetime), for 2 interviews, held 1 week apart, about gambling and associated behaviors. Results indicate substantial to almost-perfect DSM-IV PGD reliability for Caucasians (kappa = 0.82) and African Americans/other minorities (kappa = 0.68). Reliability for symptoms and for game-specific disorders was fair to almost perfect (kappa = 0.37-0.90). After adjusting results for confounding variables and multiple comparisons, racial/ethnic variation in PGD and game-specific reliability failed to persist. Implications exist for increased attention to screening and prevention efforts critical to reducing racial/ethnic disparities in PGD prevalence.

An analysis of stereotype threat in African American engineering students at predominantly White, ethnically diverse, and historically Black colleges and universities

Sparks, David M.

The purpose of this research was to distinguish the similarities and differences in coping strategies of African American engineering students by analyzing their perceptions of stereotype threat at three academic institution types, Predominantly White Institutions (PWI), ethnically diverse, and Historically Black Colleges and Universities (HBCUs). The researcher collected demographic and survey data using the Stereotype Vulnerability Scale (SVS). The study was offered to the entire population of African American engineering students at each college using an online survey. Results were analyzed using MANOVA and Pearson's correlational statistical analyses to test the hypotheses. Findings revealed that little differences exist between students' scores on an assessment of stereotype vulnerability, with a few areas showing that HBCUs and ethnically diverse universities are doing a similar job in addressing perceptions of their African American engineering students. Finding also revealed that the percentage of African American students at a university did not correlate with the scores on the SVS accept on questions related to the personal feelings students have about their race. The strongest findings related to the differences in male and female students across the universities. African American female engineering students appeared to perceive more stereotype threat than did their male counterparts; although, this fining was not statistically significant. Overall, no statistically significant differences were found between students' perceptions of stereotype threat at the three types of universities. Future research should expand the number of survey participants at the current universities, add more HBCUs to the study population, run similar experiments in different parts of the country, compare stereotype threat in private and elite universities, use ethnically diverse universities as models for minority student development, and use new or improved survey instruments

Full Text Available Few studies have examined physical activity and inactivity levels in an urban South African setting across 12 years of formal schooling. This information is important for implementing strategies to curb increasing trends of physical inactivity and related negative consequences, especially in low to middle income countries facing multiple challenges on overburdened health care systems. We examined levels of physical activity and sedentary behaviour cross-sectionally over 12 school years from childhood to adolescence in Black, White and Indian boys and girls. The aim of our study was to describe gender and race related patterns of physical and sedentary activity levels in a sample of South African children and to determine whether there were associations between these variables and body mass status. Physical activity questionnaires, previously validated in a South African setting, were used to gather information about activity and sedentary behaviours among 767 Black, White and Indian children (5-18 years of age across the 12 grades of formal schooling. Body mass and height were also measured. Time spent in moderate-vigorous physical activity declined over the school years for all race groups and was consistently lower for girls than boys (p = 0.03, while time spent in sedentary activity increased with increasing grade (p 0.05 whereas time spent in sedentary activities was significantly and positively correlated with body mass across all race groups: Indian (r = 0.25, p < 0.001, White (r = 0.22, p < 0.001 and Black (r = 0.37, p = 0.001.

Ethnic variability in body size, proportions and composition in children aged 5 to 11 years: is ethnic-specific calibration of bioelectrical impedance required?

Directory of Open Access Journals (Sweden)

Simon Lee

Full Text Available Bioelectrical Impedance Analysis (BIA has the potential to be used widely as a method of assessing body fatness and composition, both in clinical and community settings. BIA provides bioelectrical properties, such as whole-body impedance which ideally needs to be calibrated against a gold-standard method in order to provide accurate estimates of fat-free mass. UK studies in older children and adolescents have shown that, when used in multi-ethnic populations, calibration equations need to include ethnic-specific terms, but whether this holds true for younger children remains to be elucidated. The aims of this study were to examine ethnic differences in body size, proportions and composition in children aged 5 to 11 years, and to establish the extent to which such differences could influence BIA calibration.In a multi-ethnic population of 2171 London primary school-children (47% boys; 34% White, 29% Black African/Caribbean, 25% South Asian, 12% Other detailed anthropometric measurements were performed and ethnic differences in body size and proportion were assessed. Ethnic differences in fat-free mass, derived by deuterium dilution, were further evaluated in a subsample of the population (n = 698. Multiple linear regression models were used to calibrate BIA against deuterium dilution.In children < 11 years of age, Black African/Caribbean children were significantly taller, heavier and had larger body size than children of other ethnicities. They also had larger waist and limb girths and relatively longer legs. Despite these differences, ethnic-specific terms did not contribute significantly to the BIA calibration equation (Fat-free mass = 1.12+0.71*(height2/impedance+0.18*weight.Although clear ethnic differences in body size, proportions and composition were evident in this population of young children aged 5 to 11 years, an ethnic-specific BIA calibration equation was not required.

Gender identity felt pressure is negatively associated with adjustment indices, including self-esteem, among children and early adolescents, and both gender and ethnic-racial identity felt pressure are negatively associated with self-esteem among young adults. This study explored the longitudinal associations between gender identity and ethnic-racial identity felt pressure from family and peers to behave in either gender or race/ethnic-accordant ways, and self-esteem among a sample of 750 (49.2% female) African American (n = 194) and Latino/a youth (n = 556) (M = 12.10 years, SD = .97 years). For African Americans, the results revealed significant negative longitudinal associations between (a) ethnic-racial identity felt pressure from family at Time 1 and self-esteem at Time 2 and (b) ethnic-racial identity felt pressure from peers at Time 1 and self-esteem at Time 2, controlling for self-esteem at Time 1. These associations were not found among Latinos/as, nor were associations found between gender identity felt pressure from peers or family and self-esteem. The findings are discussed by drawing on the gender identity and ethnic-racial identity literatures.

Intra-familial and ethnic effects on attitudinal and perceptual body image: a cohort of South African mother-daughter dyads

2011-06-01

Full Text Available Abstract Background International studies suggest ethnic differences in obesity prevalence may be due, in part, to differences in body image and body size dissatisfaction between groups. Further, there is evidence to suggest that there is a familial resemblance in body image between mothers and their younger (preadolescent daughters. This research was therefore conducted to specifically identify the extent to which family status (presented as mother-daughter resemblance and ethnicity impact on body image attitudes and perceptions of South African mothers and their pre-adolescent daughters. Methods Mother-daughter dyads (n = 201, 31% black, 37% mixed ancestry and 32% white answered questions regarding their body image perception (the way they saw their body size status, their body image ideals, and body image attitudes (body size dissatisfaction in particular, presented as the Feel-Ideal Difference [FID] index score. Mothers' and daughters' body image results were compared within dyads and across ethnic groups using repeated measures of ANOVA. Results Overall, body image resemblances exist between South African mothers and their pre-adolescent daughters. Mothers and daughters chose similarly weighted silhouettes to represent their body size ideals (p = 0.308, regardless of their ethnicity or body mass index (BMI. The FID index scores were similar between mothers and their daughters only after the confounding effects of maternal BMI were removed (p = 0.685. The silhouettes chosen to represent thinness were also similar between mothers and their daughters (p = 0.960 regardless of ethnicity and maternal BMI. On the other hand, the silhouettes chosen to represent fatness were similar (p = 0.342 between mothers and their daughters, only after the confounding effects of maternal BMI were removed. Lastly, mothers and their daughters chose similarly weighted silhouettes as engendering feelings of beauty, respect and happiness (p = 0.813; p = 0.615 and p

Gibson, G.S.; Morales,

1996-02-01

Although boredom may exhibit many shared elements, culturally specific attitudes have also been found to exist. The present paper investigated boredom proneness among African-American college students. Data from 120 participants on the Boredom Proneness (BP) Scale was analyzed and compared to cross-cultural participants. African-American females scored significantly higher than African-American males. Scores were presented from two other studies to show a comparative look at boredom proneness in five other ethnic groups. African-American females are the only female ethnic group to score higher on the BP Scale than their male counterparts. Additionally, overall African-Americans, were found to have higher BP scores than their Western counterparts.

Few existing studies have addressed racial/ethnic differences in the health and quality of life of lesbian, gay, bisexual, and transgender (LGBT) older adults. Guided by the Health Equity Promotion Model, this study examines health-promoting and health risk factors that contribute to racial/ethnic health disparities among LGBT adults aged 50 and older. We utilized weighted survey data from Aging with Pride: National Health, Aging, and Sexuality/Gender Study. By applying multiple mediator models, we analyzed the indirect effects of race/ethnicity on health-related quality of life (HRQOL) via demographics, lifetime LGBT-related discrimination, and victimization, and socioeconomic, identity-related, spiritual, and social resources. Although African Americans and Hispanics, compared with non-Hispanic Whites, reported lower physical HRQOL and comparable psychological HRQOL, indirect pathways between race/ethnicity and HRQOL were observed. African Americans and Hispanics had lower income, educational attainment, identity affirmation, and social support, which were associated with a decrease in physical and psychological HRQOL. African Americans had higher lifetime LGBT-related discrimination, which was linked to a decrease in their physical and psychological HRQOL. African Americans and Hispanics had higher spirituality, which was associated with an increase in psychological HRQOL. Findings illustrate the importance of identifying both health-promoting and health risk factors to understand ways to maximize the health potential of racially and ethnically diverse LGBT older adults. Interventions aimed at health equity should be tailored to bolster identity affirmation and social networks of LGBT older adults of color and to support strengths, including spiritual resources. © The Author 2017.

Internalized Racism and Past-Year Major Depressive Disorder Among African-Americans: the Role of Ethnic Identity and Self-Esteem.

Science.gov (United States)

James, Drexler

2017-08-01

Although a large body of research focuses on discrimination as a risk for depression among African-Americans, only a dearth of research focuses on internalized racism (i.e., endorsement of negative stereotypes of one's racial group) as a risk factor. In addition, no studies have yet to examine mediators and/or moderators of the relationship between internalized racism and depression. To this end, the present study examined the mediating and moderating roles of (a) self-esteem and (b) ethnic identity on the relationship between internalized racism and past-year major depressive disorder (MDD), in a nationally representative sample of African-American adults (N = 3570) from the National Survey of American Life. Results from this study revealed an indirect association between internalized racism and past-year MDD via self-esteem, but no indirect relationship via ethnic identity. Further, results show that both self-esteem and ethnic identity individually moderate the relationship between internalized racism and past-year MDD. Collectively, these findings suggest a need to further investigate mechanisms through which internalized racism impacts mental health and factors that strengthen and/or weaken the association between internalized racism and depression.

Street-based heroin injectors represent an especially vulnerable population group subject to negative health outcomes and social stigma. Effective clinical treatment and public health intervention for this population requires an understanding of their cultural environment and experiences. Social science theory and methods offer tools to understand the reasons for economic and ethnic disparities that cause individual suffering and stress at the institutional level. We used a cross-methodological approach that incorporated quantitative, clinical, and ethnographic data collected by two contemporaneous long-term San Francisco studies, one epidemiological and one ethnographic, to explore the impact of ethnicity on street-based heroin-injecting men 45 years of age or older who were self-identified as either African American or white. We triangulated our ethnographic findings by statistically examining 14 relevant epidemiological variables stratified by median age and ethnicity. We observed significant differences in social practices between self-identified African Americans and whites in our ethnographic social network sample with respect to patterns of (1) drug consumption; (2) income generation; (3) social and institutional relationships; and (4) personal health and hygiene. African Americans and whites tended to experience different structural relationships to their shared condition of addiction and poverty. Specifically, this generation of San Francisco injectors grew up as the children of poor rural to urban immigrants in an era (the late 1960s through 1970s) when industrial jobs disappeared and heroin became fashionable. This was also when violent segregated inner city youth gangs proliferated and the federal government initiated its "War on Drugs." African Americans had earlier and more negative contact with law enforcement but maintained long-term ties with their extended families. Most of the whites were expelled from their families when they began engaging in

Migrant workers have been shown to be at a heightened level of risk for HIV, and ethnic identity has been posited to have an impact on engagement in risky sexual behaviors. Our longitudinal study examined associations between baseline and short-term changes in ethnic identity and high-risk sexual behaviors. Baseline (n = 431) and 6-month assessment (n = 270) data were obtained from a larger HIV prevention study conducted among African American and Hispanic migrant workers. Repeated-measures multivariate analysis of covariance and multiple linear regressions were used. Ethnic identity explore, a subscale of ethnic identity, was a significant predictor of overall sexual risk [F(8, 422) = 6.953, p AIDS Care. Published by Elsevier Inc. All rights reserved.

Adolescents' educational aspirations and ethnic background: The case of students of African and Latin American migrant origins in Spain

2018-02-01

Full Text Available Background: Minority students were found to have high educational aspirations, considering their background characteristics. This finding is often attributed to 'migrant optimism.' Yet, whether socioeconomic, educational, or demographic differences between and within ethnic groups mediate and/or moderate students' educational aspirations remains an inconclusive question. Objective: This study investigates the educational aspirations of children of African and Latin American migrants in Spain, looking at four critical factors: (1 family background, (2 educational performance, (3 years lived in Spain, and (4 language used at home. Methods: Data comes from the 2010 General Evaluation of Educational Diagnostic (GEED on lower-secondary students aged 14 (n = 19,293, on average. Multivariate logistic models are applied using mediation and moderation analyses. Results: Results show that (1 minority students have higher college aspirations than students of Spanish origin after accounting for parental socioeconomic status and educational performance; (2 ethnic differentials in aspirations - especially for pupils with Latin American origin - are concentrated among low-performing and disadvantaged students; (3 recent arrival in Spain is not significantly associated with differences in educational aspirations within minority groups; (4 speaking Spanish at home does not lead to differences in aspirations for pupils of African origin. Conclusions: Migrant optimism, as opposed to family language use and years of contact with the Spanish culture and society, seems to be an important factor for the high (net educational aspirations of students from African and Latin American backgrounds. Contribution: The article provides new evidence on ethnic heterogeneity in educational aspirations, being the first that uses representative data from the whole Spanish educational system.

Obesity and its related co-morbidities place a huge burden on the health care system. Patients who know they are obese may better control their weight or seek medical attention. Self-recognition may be affected by race/ethnicity, but little is known about racial/ethnic differences in knowledge of obesity's health risks. To examine awareness of obesity and attendant health risks among US whites, Hispanics and African-Americans. Cross-sectional self-administered survey. Adult patients at three general medical clinics and one cardiology clinic. Thirty-one questions regarding demographics, height and weight, and perceptions and attitudes regarding obesity and associated health risks. Multiple logistic regression was used to quantify the association between ethnicity and obesity awareness, controlling for socio-demographic confounders. Of 1,090 patients who were offered the survey, 1,031 completed it (response rate 95%); a final sample size of 970 was obtained after exclusion for implausible BMI, mixed or Asian ethnicity. Mean age was 47 years; 64% were female, 39% were white, 39% Hispanic and 22% African-American; 48% were obese (BMI ≥30 kg/m(2)). Among obese subjects, whites were more likely to self-report obesity than minorities (adjusted proportions: 95% of whites vs. 84% of African-American and 86% of Hispanics, P = 0.006). Ethnic differences in obesity recognition disappeared when BMI was >35 kg/m(2). African-Americans were significantly less likely than whites or Hispanics to view obesity as a health problem (77% vs. 90% vs. 88%, p self-identified obese patients, 99% wanted to lose weight, but only 60% received weight loss advice from their health care provider. African-Americans and Hispanics are significantly less likely to self report obesity and associated health risks. Educational efforts may be necessary, especially for patients with BMIs between 30 and 35.

Full Text Available The incidence of chronic kidney disease varies by ethnic group in the USA, with African Americans displaying a two-fold higher rate than European Americans. One of the two defining variables underlying staging of chronic kidney disease is the glomerular filtration rate. Meta-analysis in individuals of European ancestry has identified 23 genetic loci associated with the estimated glomerular filtration rate (eGFR. We conducted a follow-up study of these 23 genetic loci using a population-based sample of 1,018 unrelated admixed African Americans. We included in our follow-up study two variants in APOL1 associated with end-stage kidney disease discovered by admixture mapping in admixed African Americans. To address confounding due to admixture, we estimated local ancestry at each marker and global ancestry. We performed regression analysis stratified by local ancestry and combined the resulting regression estimates across ancestry strata using an inverse variance-weighted fixed effects model. We found that 11 of the 24 loci were significantly associated with eGFR in our sample. The effect size estimates were not significantly different between the subgroups of individuals with two copies of African ancestry vs. two copies of European ancestry for any of the 11 loci. In contrast, allele frequencies were significantly different at 10 of the 11 loci. Collectively, the 11 loci, including four secondary signals revealed by conditional analyses, explained 14.2% of the phenotypic variance in eGFR, in contrast to the 1.4% explained by the 24 loci in individuals of European ancestry. Our findings provide insight into the genetic basis of variation in renal function among admixed African Americans.

Immigrants and ethnic minorities tend to have lower life satisfaction than majority populations. However, current understanding of the drivers of these gaps is limited. Using a rich, nationally representative data set with a large sample of ethnic minorities and matched neighbourhood characteristics, we test whether first and second generation minorities experience lower life satisfaction once accounting for compositional differences and whether, specifically, neighbourhood deprivation impacts their wellbeing. We further investigate whether a larger proportion of own ethnic group in the neighbourhood improves satisfaction. We find life satisfaction is lower among ethnic minorities, and especially for the second generation, even controlling for individual and area characteristics. Neighbourhood concentration of own ethnic group is, however, associated with higher life satisfaction for Black Africans and UK born Indians and Pakistanis. The effect for Black Africans may stem from selection into areas, but findings for Indians and Pakistanis are robust to sensitivity tests. Copyright © 2016 The Authors. Published by Elsevier Inc.

Due to disparities in the use of genetic services, there has been growing interest in examining beliefs and attitudes related to genetic testing for breast and/or ovarian cancer risk among women of African descent. However, to date, few studies have addressed critical cultural variations among this minority group and their influence on such beliefs and attitudes. We assessed ethnic, racial and cultural identity and examined their relationships with perceived benefits and barriers related to genetic testing for cancer risk in a sample of 160 women of African descent (49% self-identified African American, 39% Black-West Indian/Caribbean, 12% Black-Other) who met genetic risk criteria and were participating in a larger longitudinal study including the opportunity for free genetic counseling and testing in New York City. All participants completed the following previously validated measures: (a) the multi-group ethnic identity measure (including ethnic search and affirmation subscales) and other-group orientation for ethnic identity, (b) centrality to assess racial identity, and (c) Africentrism to measure cultural identity. Perceived benefits and barriers related to genetic testing included: (1) pros/advantages (including family-related pros), (2) cons/disadvantages (including family-related cons, stigma and confidentiality concerns), and (3) concerns about abuses of genetic testing. In multivariate analyses, several ethnic identity elements showed significant, largely positive relationships to perceived benefits about genetic testing for breast and/or ovarian cancer risk, the exception being ethnic search, which was positively associated with cons/disadvantages, in general, and family-related cons/disadvantages. Racial identity (centrality) showed a significant association with confidentiality concerns. Cultural identity (Africentrism) was not related to perceived benefits and/or barriers. Ethnic and racial identity may influence perceived benefits and barriers

Genome-wide association studies (GWAS) in European populations have identified genetic risk variants associated with multiple myeloma. We performed association testing of common variation in eight regions in 1,318 patients with multiple myeloma and 1,480 controls of European ancestry and 1,305 patients with multiple myeloma and 7,078 controls of African ancestry and conducted a meta-analysis to localize the signals, with epigenetic annotation used to predict functionality. We found that variants in 7p15.3, 17p11.2, 22q13.1 were statistically significantly (P ancestry and persons of European ancestry, and the variant in 3p22.1 was associated in European ancestry only. In a combined African ancestry-European ancestry meta-analysis, variation in five regions (2p23.3, 3p22.1, 7p15.3, 17p11.2, 22q13.1) was statistically significantly associated with multiple myeloma risk. In 3p22.1, the correlated variants clustered within the gene body of ULK4 Correlated variants in 7p15.3 clustered around an enhancer at the 3' end of the CDCA7L transcription termination site. A missense variant at 17p11.2 (rs34562254, Pro251Leu, OR, 1.32; P = 2.93 × 10 -7 ) in TNFRSF13B encodes a lymphocyte-specific protein in the TNF receptor family that interacts with the NF-κB pathway. SNPs correlated with the index signal in 22q13.1 cluster around the promoter and enhancer regions of CBX7 CONCLUSIONS: We found that reported multiple myeloma susceptibility regions contain risk variants important across populations, supporting the use of multiple racial/ethnic groups with different underlying genetic architecture to enhance the localization and identification of putatively functional alleles. A subset of reported risk loci for multiple myeloma has consistent effects across populations and is likely to be functional.

Full Text Available Previous studies on facial recognition have considered widely separated populations, both geographically and culturally, making it hard to disentangle effects of familiarity with an ability to identify ethnic groups per se.We used data from a highly intermixed population of African peoples from South Africa to test whether individuals from nine different ethnic groups could correctly differentiate between facial images of two of these, the Tswana and Pedi. Individuals could not assign ethnicity better than expected by chance, and there was no significant difference between genders in accuracy of assignment. Interestingly, we observed a trend that individuals of mixed ethnic origin were better at assigning ethnicity to Pedi and Tswanas, than individuals from less mixed backgrounds. This result supports the hypothesis that ethnic recognition is based on the visual

This was a survey of a multiethnic sample of 480 cancer patients asking questions on sociodemographic characteristics and health/illness status, 3 unidimensional cancer pain scales, 2 multidimensional cancer pain scales, the Memorial Symptom Assessment Scale, and the Functional Assessment of Cancer Therapy Scale. The data were analyzed using descriptive and inferential statistics including ANOVA and hierarchical multiple regression analyses. Results The results indicated certain ethnic differences in types of pain and symptoms that patients experienced. Also, the results demonstrated significant ethnic differences in cancer pain and functional status. The VDS, VAS, FS, MPQ, and BPI scores of Non-Hispanic (N-H) Asian participants were significantly lower than those of Hispanic and N-H White participants (p<.01). The VAS and MPQ scores of N-H African American participants were significantly lower than those of Hispanic and N-H White participants (p<.01). The FACT-G scores of N-H Asian participants were significantly lower than Hispanic participants (p<.01). The findings also indicated that being N-H Asian or not was a significant predictor of the VDS, FS, and BPI scores. Discussion The findings suggest further in-depth qualitative exploration on cultural values and beliefs related to cancer pain in each ethnic group and national-scope studies with a larger number of ethnic minorities on this topic.

Full Text Available Introduction: Financial strain and discrimination are consistent predictors of negative health outcomes and maladaptive coping behaviors, including tobacco use. Although there is considerable information exploring stress and smoking, limited research has examined the relationship between patterns of stress domains and specific tobacco/nicotine product use. Even fewer studies have assessed ethnic variations in these relationships. Methods: This study investigated the relationship between discrimination and financial strain and current tobacco/nicotine product use and explored the ethnic variation in these relationships among diverse sample of US adults (N = 1068. Separate logistic regression models assessed associations between stress domains and tobacco/nicotine product use, adjusting for covariates (e.g., age, gender, race/ethnicity, and household income. Due to statistically significant differences, the final set of models was stratified by race/ethnicity. Results: Higher levels of discrimination were associated with higher odds of all three tobacco/nicotine product categories. Financial strain was positively associated with combustible tobacco and combined tobacco/nicotine product use. Financial strain was especially risky for Non-Hispanic Whites (AOR:1.191, 95%CI:1.083–1.309 and Blacks/African Americans (AOR:1.542, 95%CI:1.106–2.148, as compared to other groups, whereas discrimination was most detrimental for Asians/Pacific Islanders (AOR:3.827, 95%CI:1.832–7.997 and Hispanics/Latinas/Latinos (AOR:2.517, 95%CI:1.603–3.952. Conclusions: Findings suggest discrimination and financial stressors are risk factors for use of multiple tobacco/nicotine products, highlighting the importance of prevention research that accounts for these stressors. Because ethnic groups may respond differently to stress/strain, prevention research needs to identify cultural values, beliefs, and coping strategies that can buffer the negative consequences of

African Americans have the highest rate of obesity in the United States relative to other ethnic minority groups. Bioecological factors including neighborhood social and physical environmental variables may be important predictors of weight-related measures specifically body mass index (BMI) in African American adults. Baseline data from the Positive Action for Today's Health (PATH) trial were collected from 417 African American adults. Overall a multiple regression model for BMI was significant, showing positive associations with average daily moderate-to-vigorous physical activity (MVPA) (B =-.21, Psocial interaction (B =-.13, Psocial interaction was associated with healthier BMI, highlighting it as a potential critical factor for future interventions in underserved, African American communities.

To determine whether reproductive age, as indexed by a validated marker of ovarian reserve (antimüllerian hormone [AMH]), varies among women of different race/ethnic backgrounds. Cross-sectional study. Community-based sample. Multiethnic sample of 947 (277 white, 237 African American, 220 Latina, and 213 Chinese) healthy and regularly cycling premenopausal women, ages 25-45. None. AMH level. A multivariate model was fit examining race/ethnicity, covariates, nonlinear terms for age (age(2), age(3)), and body mass index (BMI(2), BMI(3)), and two-way interactions between race/ethnicity and each of the other predictor variables in relation to AMH. After backward elimination, significant effects included race/ethnicity (F = 8.45), age (F = 349.94), race/ethnicity-by-linear age interaction (F = 4.67), age(2) (F = 31.61), and BMI (F = 10.69). Inspection of the significant race/ethnicity-by-linear age interaction showed AMH levels were consistently lower among Latina women compared with white women across all ages, whereas AMH levels were lower among African American and Chinese women compared with the white women at younger and middle ages, respectively. The AMH levels were higher among African American compared with Latina and Chinese women at older ages. Although the results must be considered preliminary, the findings are twofold: African American women may have lower AMH levels at younger ages but experience less of a reduction in AMH with advancing age, and Latina and Chinese women compared with white women may have lower AMH levels, marking a lower ovarian reserve and a possibly increased risk for earlier menopause.

The need to achieve is common to all societies, and failure to do so may have a highly detrimental psychological impact. For those on the margins of mainstream society, especially migrants or descendants of migrants, the impact of failed or poor achievements may increase their vulnerability to mental illness. In a prospective study of schizophrenia in three ethnic groups (White, Indian and African-Caribbean) we studied the impact of goal striving and investigated whether the gap between the poor achievement and the high aspirations of members of some minority ethnic groups was potentially a factor contributing to the development of the illness. The patients and age- and sex-matched controls from their respective communities were asked to rate their perceived current levels of achievement and their past and future expectations in five domains--social standing, housing, education, employment and financial status on a 10-point scale. The control subjects from the three ethnic groups scored similarly in most areas, supporting the validity of inter-ethnic comparisons. The gap between achievement and expectations did not appear to cause high disappointment levels in any group, and in fact only in the domain of housing did the African-Caribbean patients assess their current achievement as being significantly lower than that of their matched controls. Poor housing conditions may be one of the risk factors contributing to the high incidence of schizophrenia in African-Caribbeans.

Toward a Caribbean psychology: an African-centered approach.

Science.gov (United States)

Sutherland, Marcia Elizabeth

2011-01-01

Although the Americas and Caribbean region are purported to comprise different ethnic groups, this article’s focus is on people of African descent, who represent the largest ethnic group in many countries. The emphasis on people of African descent is related to their family structure, ethnic identity, cultural, psychohistorical, and contemporary psychosocial realities. This article discusses the limitations of Western psychology for theory, research, and applied work on people of African descent in the Americas and Caribbean region. In view of the adaptations that some people of African descent have made to slavery, colonialism, and more contemporary forms of cultural intrusions, it is argued that when necessary, notwithstanding Western psychology’s limitations, Caribbean psychologists should reconstruct mainstream psychology to address the psychological needs of these Caribbean people. The relationship between theory and psychological interventions for the optimal development of people of African descent is emphasized throughout this article. In this regard, the African-centered and constructionist viewpoint is argued to be of utility in addressing the psychological growth and development of people of African descent living in the Americas and Caribbean region.

To compare lens vault between open-angle and narrow-angle eyes in African-, Caucasian-, Hispanic-, Chinese- and Filipino-Americans. In this prospective study, 436 patients with open angle and narrow angle based on the Shaffer gonioscopic grading classification underwent anterior-segment optical coherence tomography. The Zhongshan Angle Assessment Program was used to calculate lens vault. The narrow-angle group included 32 Chinese-Americans, 22 Filipino-Americans, 26 African-Americans, 24 Hispanic-Americans and 73 Caucasian-Americans. The open-angle group included 56 Chinese-Americans, 29 Filipino-Americans, 45 African-Americans, 27 Hispanic-Americans and 102 Caucasian-Americans. Linear mixed effect regression models, accounting for the use of both eyes and adjusting for age, sex, pupil diameter and spherical equivalent, were used to test for the ethnicity and angle coefficients. Tukey's multiple comparison test was used for pairwise comparisons among the open-angle racial groups. Significant difference in lens vault was found among the open-angle racial groups (P = 0.022). For the open-angle patients, mean values for the lens vault measurements were 265 ± 288 µm for Chinese-Americans, 431 ± 248 µm for Caucasian-Americans, 302 ± 213 µm for Filipino-Americans, 304 ± 263 µm for Hispanic-Americans and 200 ± 237 µm for African-Americans. Using Tukey's multiple comparison for pairwise comparisons among the open-angle racial groups, a significant difference was found between African-American and Caucasian-Americans groups (P values for the rest of the pairwise comparisons were not statistically significant. No significant difference was found among the narrow-angle racial groups (P = 0.14). Comparison between the open angle and narrow angle within each racial group revealed significant difference for all racial groups (P < 0.05). Among all the ethnicities included in this study, narrow-angle eyes have greater lens vault compared to open

Although perceived ethnic/racial discrimination is well established as a risk factor for depressive symptoms in ethnic minority youth, few studies have examined their longitudinal relationship over time. This study examined whether a negative attributional style, positive ethnic/racial affect, and emotional reactivity moderated the longitudinal relationship of perceived peer or adult discrimination and depressive symptoms in a sample of African American and Latino high school students (n = 155). African American and Latino youth who experienced increases in perceived peer discrimination also reported greater depressive symptoms over time, but positive ethnic/racial affect buffered the longitudinal association. Emotional reactivity also served as a significant moderator but only of the baseline association between perceived peer discrimination and depressive symptoms. Thus, perceived ethnic/racial discrimination appears to play a significant role in the development of depressive symptoms for ethnic minority youth, especially those who start high school with lower levels of positive ethnic/racial affect.

Ethnicity and cardiovascular risk: variations in people of African ancestry and South Asian origin.

Cappuccio, F P

Mortality from coronary heart disease (CHD), stroke and end-stage renal failure are high in South Asian migrants in the UK. This is associated with high prevalence of diabetes and hypertension. These seem to be manifestations of a metabolic syndrome with insulin resistance (hyperinsulinaemia) and central obesity (based on high waist-to-hip ratio rather than on conventional measures of body mass index). This is associated with sedentary lifestyle, high serum triglycerides and low HDL-cholesterol. Mortality from stroke and end-stage renal failure are high in black migrants to the UK (both Caribbeans and West Africans). However, CHD mortality is low in this group. This pattern of mortality is associated with high prevalence of hypertension and diabetes. This group tends to be obese (particularly women) according to conventional measures of body mass index and to have hyperinsulinaemia, low serum triglycerides and high HDL-cholesterol. Conventional risk factors such as cigarette smoking and hypercholesterolaemia are less prevalent in ethnic minority populations in the United Kingdom and unlikely to explain the differences seen between groups, although each risk factor is likely to contribute to the variation in vascular disease within each group. There is difficulty in reconciling the results of migration studies (eg, from rural to urban environments) pointing to major environmental influences on the changes in cardiovascular risk factors with the consistent pattern of disease of ethnic groups across the world and in subsequent generations, suggesting a certain degree of genetic susceptibility. Important environment-gene interplays might be underlying some of these processes. The detection and management of hypertension and diabetes are still unsatisfactory in inner city areas and show variations by ethnic origin. Strategies for the control of CHD and stroke adopted in European countries directed mostly to white populations may be inappropriate for ethnic minority

To identify racial/ethnic differences in perceived health status and differences in the factors associated with perceived health status of midlife women in four broad racial/ethnic groups in the United States. A secondary analysis of Web-based survey data. Internet communities/groups among midlife women and Internet communities/groups of racial/ethnic minorities. Participants included 491 women 40 to 60 years of age who self-identified into four broad racial/ethnic categories (Hispanic, non-Hispanic [N-H] Asian American, N-H African American, or N-H White). Data related to participants' sociodemographic, behavioral, situational, and individual health factors and their coping resources were selected based on the Comprehensive Health Seeking and Coping Paradigm. Multiple logistic regression analyses were used to identify racial/ethnic differences in perceived health status and race/ethnicity-specific factors associated with perceived health status among midlife women. Perceived health status did not differ by race/ethnicity; however, factors that were associated with perceived health status did vary by race/ethnicity. Among N-H White women, educational level, level of family income, obesity, and menopausal symptoms were significantly associated with perceived not healthy status. In Hispanic women, perceived level of physical activity and obesity were significantly associated with not healthy status. Perceived level of physical activity was the only factor significantly associated with not healthy status in N-H Asian American women, and the level of family income was the only factor associated with not healthy status in N-H African American women. In future intervention development, researchers need to consider differences among racial/ethnic groups in the factors associated with women's perceived health status.

African American male adolescents’ involvement with multiple sexual partners has important implications for public health as well as for their development of ideas regarding masculinity and sexuality. The purpose of this study was to test hypotheses regarding the pathways through which racial discrimination affects African American adolescents’ involvement with multiple sexual partners. We hypothesized that racial discrimination would engender psychological distress, which would promote attitudes and peer affiliations conducive to multiple sexual partnerships. The study also examined the protective influence of parenting practices in buffering the influence of contextual stressors. Participants were 221 African American male youth who provided data at ages 16 and 18; their parents provided data on family socioeconomic disadvantages. Of these young men, 18.5% reported having 3 or more sexual partners during the past 3 months. Structural equation models indicated that racial discrimination contributed to sexual activity with multiple partners by inducing psychological distress, which in turn affected attitudes and peer affiliations conducive to multiple partners. The experience of protective parenting, which included racial socialization, closeness and harmony in parent-child relationships, and parental monitoring, buffered the influence of racial discrimination on psychological distress. These findings suggest targets for prevention programming and underscore the importance of efforts to reduce young men’s experience with racial discrimination. PMID:25937821

AIM To determine the frequency and causes of blindness in diabetic Africans. METHODS The study was a cross-sectional survey carried out among known black diabetics consecutively admitted at the Teaching Hospital, University of Kinshasa, between 2005 and 2007. Examination methods included interviewer-administered structured questionnaire, eye examinations (visual acuity, tonometry, funduscopy), and fasting plasma glycaemia test. RESULTS Of the 227 patients examined, 15.9% had blindness. Univariate analyses showed significant association between female, severity of diabetic retinopathy, Mayombian ethnic group, use of insulin treatment, low intake of vegetables, diabetic nephropathy, open angle glaucoma and blindness in all diabetics. After logistic regression, only diabetic nephropathy, use of insulin treatment, macular oedema, Mayombian ethnic group and vegetables low intake were the independent risk factors of blindness in all diabetics. However, after logistic regression in the sub-group with diabetic retinopathy, only open angle glaucoma and proliferative diabetic retinopathy were the independent determinants of blindness. CONCLUSION The majority of the causes of blindness in these diabetic Africans are avoidable. It is recommended that appropriate diabetes care, nutrition education, periodic eye examination and laser photocoagulation facilities should be provided for treating diabetics in sub-Saharan Africa.

Positive identity development during adolescence in general is a complex process and may pose additional challenges for adolescents adopted from a different culture. Using a web-based survey design with a sample of 100 internationally adopted Asian adolescent and young adults, the present study examined the mediating role of multiple identities (i.e., ethnic, adoptive and interpersonal ego identities) in explaining the relationship between ethnic and racial socializations, ethnic neighborhood, and self-esteem. The results showed that (a) adoptive identity mediated the influence of racial socialization on psychological well-being, and (b) ethnic affirmation mediated the influence of ethnic socialization on adoptees' well-being. This study illustrates the importance of providing supportive counseling services for adoptees who are exploring their adoptive identity.

Full Text Available Abstract Background African American women are at increased risk for poor pregnancy outcomes compared to other racial-ethnic groups. Single or multiple psychosocial and behavioral factors may contribute to this risk. Most interventions focus on singular risks. This paper describes the design, implementation, challenges faced, and acceptability of a behavioral counseling intervention for low income, pregnant African American women which integrated multiple targeted risks into a multi-component format. Methods Six academic institutions in Washington, DC collaborated in the development of a community-wide, primary care research study, DC-HOPE, to improve pregnancy outcomes. Cigarette smoking, environmental tobacco smoke exposure, depression and intimate partner violence were the four risks targeted because of their adverse impact on pregnancy. Evidence-based models for addressing each risk were adapted and integrated into a multiple risk behavior intervention format. Pregnant women attending six urban prenatal clinics were screened for eligibility and risks and randomized to intervention or usual care. The 10-session intervention was delivered in conjunction with prenatal and postpartum care visits. Descriptive statistics on risk factor distributions, intervention attendance and length (i.e., with Results Forty-eight percent of women screened were eligible based on presence of targeted risks, 76% of those eligible were enrolled, and 79% of those enrolled were retained postpartum. Most women reported a single risk factor (61%; 39% had multiple risks. Eighty-four percent of intervention women attended at least one session (60% attended ≥ 4 sessions without disruption of clinic scheduling. Specific risk factor content was delivered as prescribed in 80% or more of the sessions; 78% of sessions were fully completed (where all required risk content was covered. Ninety-three percent of the subsample of intervention women had a positive view of their

Pain is a subjectively complex and universal experience. We examine research investigating ethnic group differences in experimental pain response and factors contributing to group differences. We conducted a systematic literature review and analysis of studies using experimental pain stimuli to assess pain sensitivity across multiple ethnic groups. Our search covered the period from 1944 to 2011, and used the PubMed bibliographic database; a reference source containing over 17 million citations. We calculated effect sizes; identified ethnic/racial group categories, pain stimuli, and measures; and examined findings regarding biopsychosociocultural factors contributing to ethnic/racial group differences. We found 472 studies investigating ethnic group differences and pain. Twenty-six of these met our review inclusion criteria of investigating ethnic group differences in experimental pain. The majority of studies included comparisons between African Americans (AA) and non-Hispanic Whites (NHW). There were consistently moderate to large effect sizes for pain tolerance across multiple stimulus modalities; AA demonstrated lower pain tolerance. For pain threshold, findings were generally in the same direction, but effect sizes were small to moderate across ethnic groups. Limited data were available for suprathreshold pain ratings. A subset of studies comparing NHW and other ethnic groups showed a variable range of effect sizes for pain threshold and tolerance. There are potentially important ethnic/racial group differences in experimental pain perception. Elucidating ethnic group differences has translational merit for culturally competent clinical care and for addressing and reducing pain treatment disparities among ethnically/racially diverse groups.

Treatment and control of hypertension (HTN) is a challenging issue as undiagnosed HTN prevalence seems to be high among certain ethnic groups, such as African-descendant populations. The current study attempted to measure HTN prevalence, awareness and control levels among Ghawarna, an African-descendant ethnic group living in the Jordan Valley (Al-Ghawr). A cross-sectional study was conducted in a community of Ghawarna between March and June 2013 in Ghawr Al-Mazraa Village in the southern part of the Jordan Valley. A total of 517 participants, aged >25 years, were randomly selected using cluster random sampling technique. Data were collected using an interviewer-administrated questionnaire and on-location measurement of blood pressure (BP), height, and weight. Prevalence rates were compared by sex and age groups using chi-square test while backward selection logistic regression analysis was used to identify predictors of HTN. We found 229 (44.3%) of the 517 participants had HTN. Of those 229 hypertensives, 146 (28.2%) participants were discovered to have HTN for the "first time." Only 23 of the 83 who were aware of their hypertension had their BP controlled. When we added the undiagnosed HTN (n=146) to the uncontrolled HTN (n=60), the prevalence of uncontrolled HTN became 90% (206/229). Older age, higher BMI, diabetes mellitus, and dyslipidemia were associated with having HTN. HTN prevalence, awareness and control levels are alarming among Ghawarna.

This article focuses on my interpretation of the history of ethnic minority psychology, using as a base the presentations of the contributing authors to this special issue of Cultural Diversity and Ethnic Minority Psychology. Because each contributing author has focused on a particular ethnic group or a particular aspect of history, my goal is to focus on 3 common issues and problems. First, what are the themes and issues that confronted African Americans, American Indians and Alaska Natives, Asian Americans, and Latinos? Second, what were characteristics of the ethnic leaders on whose shoulders we now stand? Third, what kinds of relationships existed between members of different ethnic minority groups?

Objectives. The purpose of the study was to investigate the relation between skin and tooth colour parameters in various ethnic groups. Materials and Methods. Saudi Arabian, Indian, African, and East Asian ethnic groups of 75 each were included in the study. The tooth colour was determined by spectrophotometer in CIELAB parameters. The skin colour was measured at earlobe, forehead, and malar locations by clinical skin photography. The data was statistically analysed by one-way ANOVA and correlation tests. Results. The "L" vale for the Saudi Arabian group had a strong correlation at earlobe location (r = 0.275), while correlation was found at forehead (r = 0.271) and malar region (r = 0.261) with Indian ethnic group. A strong negative correlation was observed in African ethnic group at all three locations for "L" parameter. The redness value "a" is found to have strong negative linear correlation between the earlobe and tooth for Saudi Arabian (r = -0.240) and Indian ethnic groups (r = -0.268). The "b" showed no correlation with skin location in all groups except positive correlation in African ethnic groups. Conclusions. The strong correlation was found between the skin and tooth colour parameters; hence the skin colour can be used as a guide for artificial tooth selection in edentulous patients.

Full Text Available Skin auto fluorescence (SAF is used as a proxy for the accumulation of advanced glycation end products (AGEs and has been proposed to stratify patients into cardiovascular disease (CVD and diabetes mellitus (DM risk groups. This study evaluates the effects of seven different ethnicities (Arab, Central-East African, Eastern Mediterranean, European, North African, South Asian and Southeast Asian and gender on SAF as well as validating SAF assessment as a risk estimation tool for CVD and DM in an Arabian cohort. SAF data from self-reported healthy 2,780 individuals, collated from three independent studies, has been linear modelled using age and gender as a covariate. A cross-study harmonized effect size (Cohens'd is provided for each ethnicity. Furthermore, new data has been collected from a clinically well-defined patient group of 235 individuals, to evaluate SAF as a clinical tool for DM and CVD-risk estimation in an Arab cohort. In an Arab population, SAF-based CVD and/or DM risk-estimation can be improved by referencing to ethnicity and gender-specific SAF values. Highest SAF values were observed for the North African population, followed by East Mediterranean, Arab, South Asian and European populations. The South Asian population had a slightly steeper slope in SAF values with age compared to other ethnic groups. All ethnic groups except Europeans showed a significant gender effect. When compared with a European group, effect size was highest for Eastern Mediterranean group and lowest for South Asian group. The Central-East African and Southeast Asian ethnicity matched closest to the Arab and Eastern Mediterranean ethnicities, respectively. Ethnic and gender-specific data improves performance in SAF-based CVD and DM risk estimation. The provided harmonized effect size allows a direct comparison of SAF in different ethnicities. For the first time, gender differences in SAF are described for North African and East Mediterranean populations.

Explaining racial/ethnic differences in all-cause mortality in the Multi-Ethnic Study of Atherosclerosis (MESA: Substantive complexity and hazardous working conditions as mediating factors

Full Text Available Research on racial/ethnic health disparities and socioeconomic position has not fully considered occupation. However, because occupations are racially patterned, certain occupational characteristics may explain racial/ethnic difference in health. This study examines the role of occupational characteristics in racial/ethnic disparities in all-cause mortality. Data are from a U.S. community-based cohort study (n=6342, median follow-up: 12.2 years, in which 893 deaths (14.1% occurred. We estimated mortality hazard ratios (HRs for African Americans, Hispanics, and Chinese Americans compared with whites. We also estimated the proportion of the HR mediated by each of two occupational characteristics, substantive complexity of work (e.g., problem solving, inductive/deductive reasoning on the job and hazardous conditions (e.g., noise, extreme temperature, chemicals, derived from the Occupational Information Network database (O*NET. Analyses were adjusted for age, sex, nativity, working status at baseline, and study sites. African Americans had a higher rate of all-cause death (HR 1.41; 95% confidence interval [CI]: 1.19–1.66 than whites. Chinese-American ethnicity was protective (HR 0.59, CI: 0.40–0.85; Hispanic ethnicity was not significantly different from whites (HR 0.88; CI: 0.67–1.17. Substantive complexity of work mediated 30% of the higher rate of death for African Americans compared with whites. For other groups, mediation was not significant. Hazardous conditions did not significantly mediate mortality in any racial/ethnic group. Lower levels of substantive complexity of work mediate a substantial part of the health disadvantage in African Americans. This job characteristic may be an important factor in explaining racial health disparities.

Body mass index (BMI) is often used as a surrogate estimate of percent body fat in epidemiological studies. This study tested the hypothesis that BMI is representative of body fatness independent of age, sex, ethnicity, and geographic location in prepubertal children. The study sample included a total of 605 prepubertal children (275 girls and 330 boys) of which 247 were Chinese from Jinan, Shandong, Mainland China, and 358 children were from various ethnic backgrounds in New York City (NYC): 121 Caucasians, 94 African Americans, and 143 Asians (Chinese and Korean). In this cross-sectional study, dual energy X-ray absorptiometry was used to quantify total body fat (TBF) and percent body fat (PBF). Prepubertal status was assessed by the criteria of Tanner. Multiple regression models were developed with TBF and PBF as the dependent variables and BMI, age, sex, and ethnicity as independent variables. Multiple regression analysis showed that BMI alone explained 85% and 69% of between-subject variance for TBF and PBF, respectively. Sex was a significant contributor to the models (P < 0.001) with girls having higher TBF and PBF than boys. Ethnicity and geographic location were significant contributors to the model (P < 0.0001) with Asians (Jinan and NYC Asians) having higher PBF than all non-Asian groups (P < 0.0001), and Jinan Asians having higher TBF and PBF than NYC-Asians. Among prepubertal children, for the same BMI, Asians have significantly higher PBF compared with African Americans and Caucasians. Caution is warranted when applying BMI across sex and ethnic prepubertal groups. PMID:19541740

Differences in ocular anatomy may contribute to ethnic differences in glaucoma risk. Because the trabecular meshwork (TM) plays an important role in aqueous outflow, its anatomy in relation to at-risk populations may provide insight into a potential contributor to elevated intraocular pressure and thus to probability of glaucoma development. To investigate whether differences exist in TM height between ethnic groups. This prospective study took place from January 1, 2012, to December 31, 2013. Adult patients who self-reported as being of white, Asian, Hispanic, or African American ethnicity were recruited from ophthalmology clinics at the University of California, San Francisco. The TM height was assessed using spectral-domain anterior segment optical coherence tomography. Trabecular meshwork height was measured from the scleral spur to the Schwalbe line. We hypothesized that ethnicities with a higher prevalence of glaucoma would tend to have shorter TM heights. We collected data from 460 eyes of 291 participants after excluding 34 optical coherence tomographic scans owing to poor image quality. The final sample was 32.2% white, 45.1% Asian, 10.5% African American, and 12.1% Hispanic. There were 64.2% women, and the mean age was 68.1 years. The mean (SD) TM height among all eyes included in the study was 836 (131) μm. The mean (SD) TM height was characterized among white (851 [131] μm), Asian (843 [126] μm), Hispanic (822 [147] μm), and African American (771 [118] μm) persons. Ethnicity was not associated with TM height overall (P = .23, linear mixed regression model). However, the TM heights of African American participants (771 μm) were shorter than those of white (851 μm; adjusted difference 95% CI, -119.8 to -8.1; P = .02) and Asian (843 μm; adjusted difference 95% CI, -117.4 to -10.8; P = .02) participants. Although TM height is not associated with ethnicity overall, African American individuals have shorter TM heights compared with Asian and white

Little is known about levels of physical fitness in children from different ethnic groups in the UK. We therefore studied physical fitness in UK children (aged 9-10 years) of South Asian, black African-Caribbean and white European origin. Cross-sectional study. Primary schools in the UK. 1625 children (aged 9-10 years) of South Asian, black African-Caribbean and white European origin in the UK studied between 2006 and 2007. A step test assessed submaximal physical fitness from which estimated VO2 max was derived. Ethnic differences in estimated VO2 max were estimated using multilevel linear regression allowing for clustering at school level and adjusting for age, sex and month as fixed effects. The study response rate was 63%. In adjusted analyses, boys had higher levels of estimated VO2 max than girls (mean difference 3.06 mL O2/min/kg, 95% CI 2.66 to 3.47, pAfrican-Caribbeans were higher than those in white Europeans (mean difference 0.60 mL O2/min/kg, 95% CI 0.02 to 1.17, p=0.04); these patterns were similar in boys and girls. The lower estimated VO2 max in South Asians, compared to white Europeans, was consistent among Indian, Pakistani and Bangladeshi children and was attenuated by 78% after adjustment for objectively measured physical activity (average daily steps). South Asian children have lower levels of physical fitness than white Europeans and black African-Caribbeans in the UK. This ethnic difference in physical fitness is at least partly explained by ethnic differences in physical activity. Published by the BMJ Publishing Group Limited.

Objective This cross-sectional study examined racial/ethnic differences in meeting the 2008 U.S. Department of Health and Human Services Physical Activity Guidelines aerobic component (≥ 150 moderate-to-vigorous (MV) minutes/week in bouts ≥ 10 minutes) among persons with or at risk for radiographic knee osteoarthritis (RKOA). Methods We evaluated African American versus White differences in Guideline attainment using multiple logistic regression adjusting for socio-demographic (age, gender, site, income, education) and health factors (comorbidity, depressive symptoms, overweight/obesity, knee pain). Our analyses included adults aged 49–84 who participated in accelerometer monitoring at the Osteoarthritis Initiative 48-month visit (1142 with and 747 at risk for RKOA). Results 2.0% of African Americans and 13.0% of Whites met Guidelines. For adults with and at risk for RKOA, significantly lower rates of Guideline attainment among African Americans compared to Whites were partially attenuated by health factor differences, particularly overweight/obesity and knee pain (RKOA: adjusted odds ratio [OR] = 0.24, 95% confidence interval [CI] = [0.08, 0.72]; at risk for RKOA: OR = 0.28, 95% CI = [0.07, 1.05]). Conclusion Despite known benefits from physical activity, attainment of Physical Activity Guidelines among persons with and at risk for RKOA was low. African Americans were 72–76% less likely than Whites to meet Guidelines. Culturally-relevant interventions and environmental strategies in the African American community targeting overweight/obesity and knee pain may reduce future racial/ethnic differences in physical activity and improve health outcomes.

Stereotypes associating men and masculine traits with science, technology, engineering, and mathematics (STEM) fields are ubiquitous, but the relative strength of these stereotypes varies considerably across cultures. The present research applies an intersectional approach to understanding ethnic variation in gender-STEM stereotypes and STEM participation within an American university context. African American college women participated in STEM majors at higher rates than European American college women (Study 1, Study 2, and Study 4). Furthermore, African American women had weaker implicit gender-STEM stereotypes than European American women (Studies 2-4), and ethnic differences in implicit gender-STEM stereotypes partially mediated ethnic differences in STEM participation (Study 2 and Study 4). Although African American men had weaker implicit gender-STEM stereotypes than European American men (Study 4), ethnic differences between men in STEM participation were generally small (Study 1) or nonsignificant (Study 4). We discuss the implications of an intersectional approach for understanding the relationship between gender and STEM participation. (c) 2015 APA, all rights reserved).

To measure self-reported physical and mental functioning and associated clinical features at study entry in 3 ethnic groups with systemic sclerosis (SSc). Sixty Hispanic, 39 African American, and 104 Caucasian patients with recent-onset SSc ( fatigue scores > IBQ > clinical variables (hypertension, skin score, and percentage predicted DLCO). Scleroderma-HAQ scores had ethnic-specific associations with IBQ > AHI scores > most clinical and laboratory variables. Decreased mental component summary (MCS) scores associated with AHI > ISEL. Ethnic-specific immunogenetic variables HLA-DQB1*0202 (Caucasian) and HLA-DRB 1*11 (African American), and HLA-DQA1*0501 (Hispanic) also associated with MCS. Antinuclear autoantibodies, anti-topoisomerase I, and RNA polymerases I and III also demonstrated associations with functioning in African American and Hispanic groups. Clinical, psychosocial, and immunogenetic variables had ethnic-specific associations with perceived physical and mental functioning. Consideration of ethnic-specific psychological and behavioral support in designing more personalized, relevant therapeutic interventions for the patient may improve therapeutic efficacy in SSc.

This study examined whether social goal orientation (i.e., demonstration-approach, demonstration-avoid, and social development goals) predicts changes in ethnic segregation among 4th and 5th grade African American and European American children (n = 713, ages 9-11 years) from fall to spring. Segregation measures were (a) same-ethnicity favoritism in friendships, (b) same-ethnicity favoritism in peer group affiliations, and (c) cross-ethnicity dislike. Social goal orientation was asymmetrically associated with ethnic segregation for the 2 groups. Among African Americans, aspiring to achieve high social status predicted increases in same-ethnicity favoritism and cross-ethnicity dislike. Among European Americans, aspiring to achieve high social status predicted decreases in same-ethnicity favoritism. PsycINFO Database Record (c) 2014 APA, all rights reserved.

In this study, we evaluated the risk factors associated with overweight and obesity in 2,640 preschool children in Italy taking into account the ethnic background of the parents. Height and weight were measured and BMI was calculated. Personal and lifestyle data for the children (birth weight, type of breastfeeding, sleep duration, skipping breakfast, snacking, physical activity) and parents (ethnicity, educational level, occupation, weight, height) were collected by means of a questionnaire. Italian and Other European children generally showed the highest percentage of normal weight, while the other ethnic groups presented a greater imbalance. Overweight and obesity were high in African males, who also presented high birth weight. Breastfeeding was most common, although formula feeding was significantly higher in Italians than in immigrants. Immigrants, particularly males, tended to skip breakfast more than Italians. Physical activity was significantly higher in Italians than in immigrants. In the parents, underweight was particularly high in Italian and Other mothers. African parents had high rates of overweight and obesity and a low educational level. The most common profession was worker for the fathers and housewife for the mothers, with the exception of Italians in which clerical work prevailed. Multiple linear regression analysis showed that the BMI of children was closely related to the BMI of the parents and the birth weight. Hence, these are the most informative parameters in preventing obesity.

Ancestry information can be useful in investigations of diseases with a genetic or infectious background. As the Brazilian population is highly admixed physical traits tend to be poor indicators of ancestry. The assessment of ancestry by ancestry informative markers (AIMs) can exclude the subjectivity of self-declared ethnicity and reported family origin. We aimed to evaluate the reliability of self-reported ethnicity or reported family origin as indicators of genomic ancestry in a female population from the Southeast of Brazil. Two cohorts were included: 404 women asked to self-report their ethnicity (Pop1) and 234 women asked to report their family's origin (Pop2). Identification of AIMs was performed using a panel of 61 markers and results were plotted against parental populations-Amerindian, Western European and Sub-Saharan African-using Structure v2.3.4. In Pop1 57.4 % of women self-reported as white, 34.6 % as brown and 8.0 % as black. Median global European, Amerindian and African contributions were 66.8, 12.6 and 16.6 %. In Pop2, 66.4 % of women declared European origin, 23.9 % African origin and 26.9 % Amerindian. Median global European, Amerindian and African contributions were 80.8, 7.3 and 7.6 %, respectively. Only 31.0 and 21.0 % of the global variation in African and European contributions, respectively, could be explained by self-reported ethnicity and reported family origin only accounted for 20.0 and 5.0 % of the variations observed in African and European ancestries, respectively. Amerindian ancestry did not influence self-reported ethnicity or declared family origin. Neither self-reported ethnicity nor declared family origin are reliable indicators of genomic ancestry in these Brazilian populations.

To evaluate whether ethnicity is independently associated with vaginal microbiota (VMB) composition in women living in Amsterdam, the Netherlands, as has been shown for American women. Women (18-34 years, non-pregnant, N = 610) representing the six largest ethnic groups (Dutch, African Surinamese, South-Asian Surinamese, Turkish, Moroccan, and Ghanaian) were sampled from the population-based HELIUS study. Sampling was performed irrespective of health status or healthcare seeking behavior. DNA was extracted from self-sampled vaginal swabs and sequenced by Illumina MiSeq (16S rRNA gene V3-V4 region). The overall prevalence of VMBs not dominated by lactobacilli was 38.5%: 32.2% had a VMB resembling bacterial vaginosis and another 6.2% had a VMB dominated by Bifidobacteriaceae (not including Gardnerella vaginalis), Corynebacterium, or pathobionts (streptococci, staphylococci, Proteus or Enterobacteriaceae). The most prevalent VMB in ethnically Dutch women was a Lactobacillus crispatus-dominated VMB, in African Surinamese and Ghanaian women a polybacterial G. vaginalis-containing VMB, and in the other ethnic groups a L. iners-dominated VMB. After adjustment for sociodemographic, behavioral and clinical factors, African Surinamese ethnicity (adjusted odds ratio (aOR) 5.1, 95% confidence interval (CI) 2.1-12.0) and Ghanaian ethnicity (aOR 4.8, 95% CI 1.8-12.6) were associated with having a polybacterial G. vaginalis-containing VMB, and African Surinamese ethnicity with a L. iners-dominated VMB (aOR 2.8, 95% CI 1.2-6.2). Shorter steady relationship duration, inconsistent condom use with casual partners, and not using hormonal contraception were also associated with having a polybacterial G. vaginalis-containing VMB, but human papillomavirus infection was not. Other sexually transmitted infections were uncommon. The overall prevalence of having a VMB not dominated by lactobacilli in this population-based cohort of women aged 18-34 years in Amsterdam was high (38.5%), and

This study describes the incidence of psychosis in unemployed people and determines whether unemployment has a greater impact on the development of psychosis amongst Black minority groups than White groups. Patients with a first diagnosis of Research Diagnostic Criteria psychosis, in a defined area of London from 1998 to 2004, were identified. Crude and standardised incidence rates of psychosis amongst unemployed people for each ethnic group were calculated. Poisson regression modelling tested for interactions between unemployment and ethnicity. Hundred cases occurred amongst employed people and 78 cases occurred amongst the unemployed people. When standardised to the employed White population of the area, White unemployed people had a standardised incidence ratio (SIR) of 11.7 (95% CI 6.4-19.7), Black Caribbean people had a SIR of 60.1(95% CI 39.3-88) and Black African people had a SIR of 40.7 (95% CI 25.8-61.1). There was no interaction however between ethnicity and unemployment (Likelihood ratio test P = 0.54). Rates of psychosis are high amongst unemployed people in south London and extremely high amongst Black Caribbean and Black African unemployed people. There was no evidence however that the minority groups were particularly sensitive to the stresses, limitations or meaning of unemployment. © 2012 John Wiley & Sons A/S.

Previous work has suggested that ethnic minority women have more negative attitudes to cosmetic surgery than British Whites, but reasons for this are not fully understood. To overcome this dearth in the literature, the present study asked 250 British Asian and 250 African Caribbean university students to complete measures of attitudes to cosmetic surgery, cultural mistrust, adherence to traditional cultural values, ethnic identity salience, self-esteem, and demographics. Preliminary analyses showed that there were significant between-group differences only on cultural mistrust and self-esteem, although effect sizes were small (d values = .21-.37). Further analyses showed that more negative attitudes to cosmetic surgery were associated with greater cultural mistrust, stronger adherence to traditional values, and stronger ethnic identity salience, although these relationships were weaker for African Caribbean women than for British Asians. These results are discussed in relation to perceptions of cosmetic surgery among ethnic minority women.

Mental health functioning in American Indian youth is an understudied topic. Given the increased rates of depression and anxiety in this population, further research is needed. Using multiple group structural equation modeling, the current study illuminates the effect of ethnic identity on anxiety symptoms, depressive symptoms, and externalizing behavior in a group of Lumbee adolescents and a group of Caucasian, African American, and Latino/Hispanic adolescents. This study examined two possible pathways (i.e., future optimism and self-esteem) through which ethnic identity is associated with adolescent mental health. The sample (N = 4,714) is 28.53% American Indian (Lumbee) and 51.38% female. The study findings indicate that self-esteem significantly mediated the relationships between ethnic identity and anxiety symptoms, depressive symptoms, and externalizing behavior for all racial/ethnic groups (i.e., the total sample). Future optimism significantly mediated the relationship between ethnic identity and externalizing behavior for all racial/ethnic groups and was a significant mediator between ethnic identity and depressive symptoms for American Indian youth only. Fostering ethnic identity in all youth serves to enhance mental health functioning, but is especially important for American Indian youth due to the collective nature of their culture.

Research has documented deleterious effects of racism among ethnic minorities and of homophobia among men who have sex with men (MSM). Less is known about the impact of multiple forms of stigmatization on ethnic minority MSM. This study examined substance use by African American, Asian/Pacific Islander and Latino MSM, and the associations of experienced racism and homophobia from various sources with polydrug use and stimulant drug use. Experienced racism within the general community was associated with higher levels of use; other forms of discrimination were either not associated with polydrug or stimulant use or had more complex relationships with use. Implications for further research and interventions are discussed.

One fundamental goal in the Healthy People 2020 is to achieve health equity and eliminate disparities. To examine the annual trends in racial/ethnic disparity in obesity among US youth from 1999 to 2013. Nationally representative sample of 108,811 students in grades 9th-12th from the Youth Risk Behavior Surveillance System (YRBSS) 1999-2013 surveys. Body mass index (BMI) was calculated based on self-reported height and weight. Obesity in youth is defined as BMI at or above 95th sex- and age-specific percentile of the 2000 Centers for Disease Control and Prevention growth charts. Multiple logistic regressions were conducted to estimate the annual prevalence of obesity by race/ethnicity, adjusted for gender and age group and accounted for the YRBSS survey design. Between-group variance (BGV) was used to measure absolute racial/ethnic disparity in obesity, and the mean log deviation (MLD) and the Theil Index (T) were used to measure relative racial/ethnic disparity in obesity, weighted by corresponding racial/ethnic population size. The obesity prevalence among non-Hispanic Whites, non-Hispanic African Americans, non-Hispanic other race or multi-race, and Hispanic increased from 10.05%, 12.31%, 10.25%, and 13.24% in 1999 to 13.14%, 15.76%, 10.87%, and 15.20% in 2013, respectively. Both absolute and relative racial/ethnic disparity in obesity increased initially since 1999 but then steadily declined starting from mid-2000s back to around its original level by 2013. The obesity epidemic in youth is marked by salient and persistent disparity pertaining to race/ethnicity. No improvement on racial/ethnic disparity in obesity among American youth was observed during 1999-2013.

Socioeconomic Status, Race/Ethnicity, and Diurnal Cortisol Trajectories in Middle-Aged and Older Adults.

Slow afternoon cortisol decline may be a marker of aging. We hypothesize that lower socioeconomic status (SES) and African American race are associated with lower waking cortisol and slower afternoon decline. Six salivary cortisol samples, collected within a 24-hr period from 566 cohort participants aged 56-78 years, were examined in random-effects models. SES measures included socioeconomic vulnerability (household income and assets Accounting for African American race/ethnicity, socioeconomic vulnerability was associated with a 3% faster decline, and education was not associated with cortisol. African Americans had 26% lower average waking cortisol and 1% slower decline than others. African American race/ethnicity, but not lower SES, was associated with lower waking cortisol and slower afternoon decline in middle-aged and older adults. This pattern is likely a marker of earlier biological aging in vulnerable groups. Race/ethnicity may compete with SES as a measure of cumulative vulnerability.

Behçet's disease (BD) significantly increases morbidity and mortality. BD mainly affects young adults with a peculiar geographical distribution. It has been suggested that BD varies in its phenotypic expression in different ethnic groups. We investigated potential ethnicity-related differences relative to phenotype and prognosis of BD patients in a French multiethnic country. We included 769 consecutive patients fulfilling the international criteria of classification for BD, in the 3 largest ethnic groups of our cohort [European (n = 369), North African (n = 350) and sub Saharan African (n = 50)]. Factors that affect prognosis were assessed by multivariate analysis. 535 (69.6%) patients were male and the median (IQR) age at diagnosis was of 30.9 (24.9-37.2) years. Sub Saharan African BD patients had a higher frequency of CNS involvement (48% vs 32.3% vs 29.5%, p = 0 .035), a higher rate of death (12% vs 6% vs 3.5%, p = 0.029) and a lower frequency of HLA B51 allele (29.4% vs 49.2% vs 55.8%, p = 0.009) compared to those from North Africa and Europe, respectively. Multivariate analysis showed that male gender (HR: 5.01, CI: 1.51-16.65), cardiovascular involvement (HR: 2.24, CI: 1.15-4.36), and sub Saharan African origin (HR 2.62 (0.98-6.97) were independently associated with mortality. The 15-year mortality rate was of 19%, 9% and 6% in sub Saharan African, North African and European BD patients, respectively (p = 0.015). We reported ethnicity-related differences with respect to phenotype of BD. Sub Saharan Africans patients exhibited a worse prognosis.

Background Bioelectrical impedance analysis (BIA) is a potentially valuable method for assessing lean mass and body fat levels in children from different ethnic groups. We examined the need for ethnic- and gender-specific equations for estimating fat free mass (FFM) from BIA in children from different ethnic groups and examined their effects on the assessment of ethnic differences in body fat. Methods Cross-sectional study of children aged 8–10 years in London Primary schools including 325 South Asians, 250 black African-Caribbeans and 289 white Europeans with measurements of height, weight and arm-leg impedance (Z; Bodystat 1500). Total body water was estimated from deuterium dilution and converted to FFM.

Bioelectrical impedance analysis (BIA) is a potentially valuable method for assessing lean mass and body fat levels in children from different ethnic groups. We examined the need for ethnic- and gender-specific equations for estimating fat free mass (FFM) from BIA in children from different ethnic groups and examined their effects on the assessment of ethnic differences in body fat. Cross-sectional study of children aged 8-10 years in London Primary schools including 325 South Asians, 250 black African-Caribbeans and 289 white Europeans with measurements of height, weight and arm-leg impedance (Z; Bodystat 1500). Total body water was estimated from deuterium dilution and converted to FFM. Multilevel models were used to derive three types of equation {A: FFM = linear combination(height+weight+Z); B: FFM = linear combination(height(2)/Z); C: FFM = linear combination(height(2)/Z+weight)}. Ethnicity and gender were important predictors of FFM and improved model fit in all equations. The models of best fit were ethnicity and gender specific versions of equation A, followed by equation C; these provided accurate assessments of ethnic differences in FFM and FM. In contrast, the use of generic equations led to underestimation of both the negative South Asian-white European FFM difference and the positive black African-Caribbean-white European FFM difference (by 0.53 kg and by 0.73 kg respectively for equation A).

Consistent results were observed when the equations were applied to a large external data set. Ethnic- and gender-specific equations for predicting FFM from BIA provide better estimates of ethnic differences in FFM and FM in children, while generic equations can misrepresent these ethnic differences.

Natriuretic peptides (NP) are cardiac-derived hormones with favorable cardiometabolic actions. Low NP levels are associated with increased risks of hypertension and diabetes mellitus, conditions with variable prevalence by race and ethnicity. Heritable factors underlie a significant proportion of the interindividual variation in NP concentrations, but the specific influences of race and ancestry are unknown. In 5597 individuals (40% white, 24% black, 23% Hispanic, and 13% Chinese) without prevalent cardiovascular disease at baseline in the Multi-Ethnic Study of Atherosclerosis, multivariable linear regression and restricted cubic splines were used to estimate differences in serum N-terminal pro B-type natriuretic peptide (NT-proBNP) levels according to, ethnicity, and ancestry. Ancestry was determined using genetic ancestry informative markers. NT-proBNP concentrations differed significantly by race and ethnicity (black, median 43 pg/ml [interquartile range 17 to 94], Chinese 43 [17 to 90], Hispanic 53 [23 to 107], white 68 [34 to 136]; p = 0.0001). In multivariable models, NT-proBNP was 44% lower (95% confidence interval -48 to -40) in black and 46% lower (-50 to -41) in Chinese, compared with white individuals. Hispanic individuals had intermediate concentrations. Self-identified blacks and Hispanics were the most genetically admixed. Among self-identified black individuals, a 20% increase in genetic European ancestry was associated with 12% higher (1% to 23%) NT-proBNP. Among Hispanic individuals, genetic European and African ancestry were positively and negatively associated with NT-proBNP levels, respectively. In conclusion, NT-proBNP levels differ according to race and ethnicity, with the lowest concentrations in black and Chinese individuals. Racial and ethnic differences in NT-proBNP may have a genetic basis, with European and African ancestry associated with higher and lower NT-proBNP concentrations, respectively.

Copy number variations (CNVs) are structural genetic mutations consisting of segmental gains or losses in DNA sequence. Although CNVs contribute substantially to genomic variation, few genetic and imaging studies report association of CNVs with alcohol dependence (AD). Our purpose is to find evidence of this association across ethnic populations and genders. This work is the first AD-CNV study across ethnic groups and the first to include the African American (AA) population. This study considers 2 CNV data sets, one for discovery (2,345 samples) and the other for validation (239 samples), both including subjects with AD and healthy controls of European and African ancestry. Our analysis assesses the association between AD and CNV losses across ethnic groups and gender by examining the effect of overall losses across the whole genome, collective losses within individual cytogenetic bands, and specific losses in CNV regions. Results from the discovery data set showed an association between CNV losses within 16q12.2 and AD diagnosis (p = 4.53 × 10(-3) ). An overlapping CNV region from the validation data set exhibited the same direction of effect with respect to AD (p = 0.051). This CNV region affects the genes CES1p1 and CES1, which are members of the carboxylesterase (CES) family. The enzyme encoded by CES1 is a major liver enzyme that typically catalyzes the decomposition of ester into alcohol and carboxylic acid and is involved in drug or xenobiotics, fatty acid, and cholesterol metabolisms. In addition, the most significantly associated CNV region was located at 9p21.2 (p = 1.9 × 10(-3) ) in our discovery data set. Although not observed in the validation data set, probably due to small sample size, this result might hold potential connection to AD given its connection with neuronal death. In contrast, we did not find any association between AD and the overall total losses or the collective losses within individual cytogenetic bands. Overall, our study provides

Ethnic identity is an important buffer against drug use among minority youth. However, limited work has examined pathways through which ethnic identity mitigates risk. School-aged youth (N = 34,708; 52 % female) of diverse backgrounds (i.e., African American (n = 5333), Asian (n = 392), Hispanic (n = 662), Multiracial (n = 2129), Native American (n = 474), and White (n = 25718) in grades 4-12 provided data on ethnic identity, drug attitudes, and drug use. After controlling for gender and grade, higher ethnic identity was associated with lower past month drug use for African American, Hispanic, and Multiracial youth. Conversely, high ethnic identity was associated with increased risk for White youth. An indirect pathway between ethnic identity, drug attitudes, and drug use was also found for African American, Hispanic, and Asian youth. Among White youth the path model was also significant, but in the opposite direction. These findings confirm the importance of ethnic identity for most minority youth. Further research is needed to better understand the association between ethnic identity and drug use for Multiracial and Hispanic youth, best ways to facilitate healthy ethnic identity development for minority youth, and how to moderate the risk of identity development for White youth.

The higher risk of heart failure (HF) in African-American and Hispanic women compared with white women is related to the higher burden of risk factors (RFs) in minorities. However, it is unclear if there are differences in the association between the number of RFs for HF and the risk of development of HF and death within racial/ethnic groups. In the WHI (Women's Health Initiative; 1993-2010), African-American (n=11 996), white (n=18 479), and Hispanic (n=5096) women with 1, 2, or 3+ baseline RFs were compared with women with 0 RF within their respective racial/ethnic groups to assess risk of developing HF or all-cause mortality before and after HF, using survival analyses. After adjusting for age, socioeconomic status, and hormone therapy, the subdistribution hazard ratio (95% confidence interval) of developing HF increased as number of RFs increased ( P ethnicity and RF number P =0.18)-African-Americans 1 RF: 1.80 (1.01-3.20), 2 RFs: 3.19 (1.84-5.54), 3+ RFs: 7.31 (4.26-12.56); Whites 1 RF: 1.27 (1.04-1.54), 2 RFs: 1.95 (1.60-2.36), 3+ RFs: 4.07 (3.36-4.93); Hispanics 1 RF: 1.72 (0.68-4.34), 2 RFs: 3.87 (1.60-9.37), 3+ RFs: 8.80 (3.62-21.42). Risk of death before developing HF increased with subsequent RFs ( P ethnic group (interaction P =0.001). The number of RFs was not associated with the risk of death after developing HF in any group ( P =0.25; interaction P =0.48). Among diverse racial/ethnic groups, an increase in the number of baseline RFs was associated with higher risk of HF and death before HF but was not associated with death after HF. Early RF prevention may reduce the burden of HF across multiple racial/ethnic groups. © 2018 American Heart Association, Inc.

Previous research addressing the dynamics of stigma and academics has focused on African-American adolescents and adults. The present study examined stigma awareness, academic anxiety, and intrinsic motivation among 451 young (ages 6–11) and diverse (African-American, Chinese, Dominican, Russian, and European-American) students. Results indicated that ethnic-minority children reported higher stigma awareness than European-American children. For all children, stigma awareness was associated with higher academic anxiety and lower intrinsic motivation. Despite these associations, ethnic-minority children reported higher levels of intrinsic motivation than their European-American peers. A significant portion of the higher intrinsic motivation among Dominican students was associated with their higher levels of school belonging, suggesting that supportive school environments may be important sources of intrinsic motivation among some ethnic-minority children.

Africa is the source of all modern humans, but characterization of genetic variation and of relationships among populations across the continent has been enigmatic. We studied 121 African populations, four African American populations, and 60 non-African populations for patterns of variation at 1327 nuclear microsatellite and insertion/deletion markers. We identified 14 ancestral population clusters in Africa that correlate with self-described ethnicity and shared cultural and/or linguistic properties. We observed high levels of mixed ancestry in most populations, reflecting historical migration events across the continent. Our data also provide evidence for shared ancestry among geographically diverse hunter-gatherer populations (Khoesan speakers and Pygmies). The ancestry of African Americans is predominantly from Niger-Kordofanian (~71%), European (~13%), and other African (~8%) populations, although admixture levels varied considerably among individuals. This study helps tease apart the complex evolutionary history of Africans and African Americans, aiding both anthropological and genetic epidemiologic studies. PMID:19407144

The Perceptions of STEM from Eighth-Grade African-American Girls in a High-Minority Middle School

Science.gov (United States)

Hare, LaChanda N.

Even with the existence of STEM curriculum and STEM programs that target women and minorities, African-American females still lag behind other ethnic groups in STEM fields. Reasons for the underrepresentation of females in STEM fields can be traced back to the early years of schooling. The purpose of this study was to identify the factors that impact African-American females' perspectives of STEM subjects and STEM careers. An explanatory sequential mixed-methods approach was used for data collection with a survey, focus group, and interview. Forty male (N=12) and female (N=28) students from different ethnic groups were surveyed. The focus group and interview sessions consisted of 21 African-American females from two distinct groups: those enrolled in the school's STEM program (STEM) and those who were not enrolled in the STEM program (Non-STEM). The self-efficacy theory and social cognitive career theory served as the theoretical constructs guiding the data analysis. Multiple regression results showed that outcome expectation and personal disposition had the greatest influence on the females' interest in STEM content and STEM careers. Results from the qualitative portion of the study revealed that the learning environment and STEM self-efficacy had a significant impact on African-American females' interest in STEM.

Gene-centric meta-analysis of lipid traits in African, East Asian and Hispanic populations.

Directory of Open Access Journals (Sweden)

Clara C Elbers

Full Text Available Meta-analyses of European populations has successfully identified genetic variants in over 100 loci associated with lipid levels, but our knowledge in other ethnicities remains limited. To address this, we performed dense genotyping of ∼2,000 candidate genes in 7,657 African Americans, 1,315 Hispanics and 841 East Asians, using the IBC array, a custom ∼50,000 SNP genotyping array. Meta-analyses confirmed 16 lipid loci previously established in European populations at genome-wide significance level, and found multiple independent association signals within these lipid loci. Initial discovery and in silico follow-up in 7,000 additional African American samples, confirmed two novel loci: rs5030359 within ICAM1 is associated with total cholesterol (TC and low-density lipoprotein cholesterol (LDL-C (p = 8.8×10(-7 and p = 1.5×10(-6 respectively and a nonsense mutation rs3211938 within CD36 is associated with high-density lipoprotein cholesterol (HDL-C levels (p = 13.5×10(-12. The rs3211938-G allele, which is nearly absent in European and Asian populations, has been previously found to be associated with CD36 deficiency and shows a signature of selection in Africans and African Americans. Finally, we have evaluated the effect of SNPs established in European populations on lipid levels in multi-ethnic populations and show that most known lipid association signals span across ethnicities. However, differences between populations, especially differences in allele frequency, can be leveraged to identify novel signals, as shown by the discovery of ICAM1 and CD36 in the current report.

Full Text Available Using data from a natural experiment in Denver, we investigate whether the initiation of running away from home, aggressive or violent behavior, and marijuana use during adolescence are statistically related to the neighborhood contexts in which low-income Latino and African American youth were raised. Our analysis is based on retrospective child, caregiver, household, and neighborhood data for a sample of approximately 850 Latino and African American youth whose families were quasi-randomly assigned to public housing operated by the Denver (CO Housing Authority during part of their childhood. We used Cox PH models and accelerated failure time models to estimate ethnic differentials in the hazards and timing of initiation of these risky behaviors during adolescence. We found that multiple dimensions of neighborhood context—especially safety, ethnic and nativity composition, and socioeconomic status—strongly and robustly predicted initiation of running away, aggressive or violence behavior, and marijuana use during adolescence.

Developmental and ethnic issues experienced by emerging adult African American women related to developing a mature love relationship.

Science.gov (United States)

Tyson, Sheryl Y

2012-01-01

This qualitative study explored perspectives of emerging adult African American women on the development of mature love relationships. Inductive analysis of focus group interviews, conducted with a purposive sample of 31 African American women, yielded themes related to relationship goals and characteristics, and interpersonal and societal challenges to finding the right partner and developing a mature love relationship. Core categories that emerged from analysis of the discussions were (1) age and relationship goal differences within the emerging adult group, (2) mature love relationship goals and characteristics, (3) interpersonal obstacles to finding the right partner, and (4) societal obstacles to finding the right partner. Two approaches-black womanist/feminist thought (Collins, 2000 ; Walker, 1983 ) and relationship maturity theory (Paul & White, 1990 )-were then combined to explain the influence of historic and contemporary interpersonal and societal factors on developmental and ethnic issues that challenge positive gender identity formation, hasten intimacy maturity, and hinder the development of mature love relationships among emerging adult African American women. For these women, premature responsibility, especially early caregiver burden, was related to the early development of intimacy capacity and the desire for a mature love relationship, to be protected, and to have someone to help carry the load. Interracial dating, negative stereotypic images of African American women, and even positive images of enduring black love relationships posed difficult challenges to positive identity formation and intimacy maturity. A primary challenge was to counteract negative stereotypic images, so that they could develop their own self-identities as women and as relationship partners.

Ethnic/racial minorities encounter disparities in healthcare, which may carry into end-of-life (EOL) care. Advanced cancer, highly prevalent and morbid, presents with worsening symptoms, heightening the need for supportive and EOL care. To conduct a systematic review examining ethnic/racial disparities in EOL care for cancer patients. We searched four electronic databases for all original research examining EOL care use, preferences, and beliefs for cancer patients from ethnic/racial minority groups. Twenty-five studies were included: 20 quantitative and five qualitative. All had a full-text English language article and focused on the ethnic/racial minority groups of African Americans, Hispanics Americans, or Asian Americans. Key themes included EOL decision making processes, family involvement, provider communication, religion and spirituality, and patient preferences. Hospice was the most studied EOL care, and was most used among Whites, followed by use among Hispanics, and least used by African and Asian Americans. African Americans perceived a greater need for hospice, yet more frequently had inadequate knowledge. African Americans preferred aggressive treatment, yet EOL care provided was often inconsistent with preferences. Hispanics and African Americans less often documented advance care plans, citing religious coping and spirituality as factors. EOL care differences among ethnic/racial minority cancer patients were found in the processes, preferences, and beliefs regarding their care. Further steps are needed to explore the exact causes of differences, yet possible explanations include religious or cultural differences, caregiver respect for patient autonomy, access barriers, and knowledge of EOL care options. © The Author(s) 2014.

Most of the existing sociological and epidemiological literature has focused on the protective effects of high socioeconomic status (SES) on population health through reducing exposure to risk factors and increasing human and material resources that can mitigate adversities. Recent studies, however, have documented poor mental health of high SES Blacks, particularly African American males and Caribbean Black females. The literature also shows a link between perceived discrimination and poor mental health. To better understand the extra costs of upward social mobility for minority populations, this study explored ethnic by gender variations in the associations between SES indicators and perceived discrimination in an ethnically diverse national sample of Black youth. This study included 810 African American and 360 Caribbean Black youth who were sampled in the National Survey of American Life-Adolescent supplement (NSAL-A). Three SES indicators (financial hardship, family income, and income to needs ratio) were the independent variables. The dependent variable was perceived (daily) discrimination. Age was the covariate. Ethnicity and gender were the focal moderators. Linear regressions were used for data analysis in the pooled sample and also based on the intersection of ethnicity and gender. Considerable gender by ethnicity variations were found in the patterns of the associations between SES indicators and perceived discrimination. Financial hardship was a risk factor for perceived discrimination in African American males only. High family income and income to needs ratio were associated with high (but not low) perceived discrimination in African American males and Caribbean Black females. SES indicators were not associated with perceived discrimination for African American females or Caribbean Black males. When it comes to Black youth, high SES is not always protective.

Poor patient-provider interaction among racial/ethnic minorities is associated with disparities in health care. In this descriptive, cross-sectional study, we examine African American women's perspectives and experiences of patient-provider interaction (communication and perceived discrimination) during their initial prenatal visit and their influences on perceptions of care received and prenatal health behaviors. Pregnant African American women (n = 204) and their providers (n = 21) completed a pre- and postvisit questionnaire at the initial prenatal visit. Women were also interviewed face to face at the subsequent return visit. Women perceived high quality patient-provider communication (PPC) and perceived low discrimination in their interaction with providers. Multiple regression analyses showed that PPC had a positive effect on trust in provider (p prenatal care satisfaction (p prenatal health behaviors. Findings suggest that quality PPC improves the prenatal care experience for African American women. © The Author(s) 2014.

To present racial/ethnic comparisons of comprehensive profiles of nursing home residents at admission, including whites, African Americans, Hispanics, Asians/Pacific Islanders, and American Indians/Alaska Natives. More than 885,000 admission assessments recorded in the national Minimum Data Set (MDS) were analyzed. Racial and ethnic analyses of the MDS admission assessments were conducted using the software package SAS. There were significant racial/ethnic differences in gender and age, with minority residents more likely to be male and younger. African American, Hispanic, and Asian/Pacific Islanders were significantly more likely than white residents to exhibit total dependence in the self-performance of the ADLs and to have greater cognitive impairments, with Asian/Pacific Islanders the most physically dependent and cognitively impaired. The results illustrate significant and substantive differences among the racial/ethnic groups for many demographic characteristics, as well as health-related indicators and conditions. This analysis suggests that the general perspective that economically disadvantaged minorities enter nursing homes in worse condition than whites is too simplistic. More research, particularly qualitative studies of specific minority groups, will advance our understanding of why members of some racial/ethnic groups require nursing home placement sooner than other groups.

Previous studies in dementia epidemiology have reported higher Alzheimer's disease rates in African-Americans when compared with White Americans. To determine whether genetically determined African ancestry is associated with neuropathological changes commonly associated with dementia, we analyzed a population-based brain bank in the highly admixed city of São Paulo, Brazil. African ancestry was estimated through the use of previously described ancestry-informative markers. Risk of presence of neuritic plaques, neurofibrillary tangles, small vessel disease, brain infarcts and Lewy bodies in subjects with significant African ancestry versus those without was determined. Results were adjusted for multiple environmental risk factors, demographic variables and apolipoprotein E genotype. African ancestry was inversely correlated with neuritic plaques (P=0.03). Subjects with significant African ancestry (n=112, 55.4%) showed lower prevalence of neuritic plaques in the univariate analysis (odds ratio (OR) 0.72, 95% confidence interval (CI) 0.55-0.95, P=0.01) and when adjusted for age, sex, APOE genotype and environmental risk factors (OR 0.43, 95% CI 0.21-0.89, P=0.02). There were no significant differences for the presence of other neuropathological alterations. We show for the first time, using genetically determined ancestry, that African ancestry may be highly protective of Alzheimer's disease neuropathology, functioning through either genetic variants or unknown environmental factors. Epidemiological studies correlating African-American race/ethnicity with increased Alzheimer's disease rates should not be interpreted as surrogates of genetic ancestry or considered to represent African-derived populations from the developing nations such as Brazil.

A variety of in utero factors have been associated with risk of adult cancers, particularly birth weight, toxemia, and gestational age. These factors are thought to reflect hormonal exposures during pregnancy. We hypothesized that the prenatal hormonal milieu may explain part of the variation in cancer rates across ethnic groups, for example, the higher incidence of breast cancer in the Caucasian compared with Hispanic women and the higher incidence of prostate and lower incidence of testicular cancers among African-Americans compared with Caucasians. We measured hormones in early pregnancy blood samples from three ethnic groups in a health care plan in Boston, MA. Mean levels of androstenedione, testosterone, estrone, and prolactin were significantly lower in Caucasian women compared with Hispanic women. Although not statistically significant, estradiol levels were lower in Caucasian compared with Hispanic or African-American women. Concentrations of androstenedione, testosterone, and progesterone were notably higher in African-American compared with Caucasian or Hispanic women. These data are consistent with hypotheses that in utero hormonal exposures may explain some of the ethnic group differences in cancer risk.

Weight changes in African American college students: a review of literature.

Science.gov (United States)

Darden, Shavon

2014-01-01

Over one-third of all adults in the United States are obese and African Americans represent over 49.5% of these cases. Young adults with some college education show the most rapid increase in the prevalence of overweight and obesity, with African Americans leading among all groups. The purpose of this paper is to consider why students gain weight in college and if racial and ethnic differences exist in the context of weight gain. Both physical environment and psychological factors affect the college students' weight-related behaviors. College students experience significant increases in their weight and African Americans are disproportionately affected. However, the role of race and ethnicity is under-examined. Future research should explore racial and ethnic differences in weight gain in college students.

Optimal waist-to-height ratio values for cardiometabolic risk screening in an ethnically diverse sample of South African urban and rural school boys and girls.

Tandi E Matsha

Full Text Available BACKGROUND: The proposed waist-to-height ratio (WHtR cut-off of 0.5 is less optimal for cardiometabolic risk screening in children in many settings. The purpose of this study was to determine the optimal WHtR for children from South Africa, and investigate variations by gender, ethnicity and residence in the achieved value. METHODS: Metabolic syndrome (MetS components were measured in 1272 randomly selected learners, aged 10-16 years, comprising of 446 black Africans, 696 mixed-ancestry and 130 Caucasians. The Youden's index and the closest-top-left (CTL point approaches were used to derive WHtR cut-offs for diagnosing any two MetS components, excluding the waist circumference. RESULTS: The two approaches yielded similar cut-off in girls, 0.465 (sensitivity 50.0, specificity 69.5, but two different values in boys, 0.455 (42.9, 88.4 and 0.425 (60.3, 67.7 based on the Youden's index and the CTL point, respectively. Furthermore, WHtR cut-off values derived differed substantially amongst the regions and ethnic groups investigated, whereby the highest cut-off was observed in semi-rural and white children, respectively, Youden's index0.505 (31.6, 87.1 and CTL point 0.475 (44.4, 75.9. CONCLUSION: The WHtR cut-off of 0.5 is less accurate for screening cardiovascular risk in South African children. The optimal value in this setting is likely gender and ethnicity-specific and sensitive to urbanization.

There are no longitudinal pQCT data of bone growth and development from sub-Saharan Africa, where rapid environmental, societal, and economic transitions are occurring, and where fracture rates are predicted to rise. The aim of this study was to compare skeletal development in black and white South African adolescents using longitudinal data from the Birth to Twenty study. The Birth to Twenty Bone Health subcohort consisted of 543 adolescents (261 [178 black] girls, 282 [201 black] boys). Annual pQCT measurements of the radial and tibial metaphysis and diaphysis were obtained between ages 12 and 22 years (distal metaphysis: cross-sectional area [CSA] and trabecular bone mineral density [BMD]; diaphysis: total and cortical CSA, cortical BMD, and polar stress-strain index [SSIp]). Age at peak height velocity (APHV) was calculated to account for differences in maturational timing between ethnic groups and sexes. Mixed-effects models were used to describe trajectories for each pQCT outcome. Likelihood-ratio tests were used to summarize the overall difference in trajectories between black and white participants within each sex. APHV (mean ± SD years) was similar in black (11.8 ± 0.8) and white (12.2 ± 1.0) girls, but delayed in black (14.2 ± 1.0) relative to white boys (13.3 ± 0.8). By 4 years post-APHV, white adolescents had significantly greater cortical CSA and SSIp than black adolescents at the radius. There were no significant differences at the radial metaphysis but there was some divergence, such that black adolescents had greater radial trabecular BMD by the end of follow-up. At the tibia, white adolescents had lower diaphyseal CSA and SSIp, and greater metaphyseal CSA. There was no ethnic difference in tibial trabecular BMD. There are ethnic differences in bone growth and development, independent of maturation, in South African adolescents. This work gives new insights into the possible etiology of childhood fractures, which occur most

Psychosocial vulnerabilities were added to a model of healthcare utilization. This extension was tested among low-income women with ethnicity addressed as a moderator. Structured interviews were conducted at 2 points in time, approximately 1 year apart. The constructs of psychosocial vulnerability, demographic predisposing, barriers, and illness were measured by multiple indicators to allow use of Structural Equation Modeling to analyze results. The models were tested separately for each ethnic group. Community office. African-American (N = 266), Euro-American (N = 200), and Mexican-American (N = 210) women were recruited from the Dallas Metropolitan area to participate in Project Health Outcomes of Women, a multi-year, multi-wave study. Face-to-face interviews were conducted with this sample. Participants had been in heterosexual relationships for at least 1 year, were between 20 and 49 years of age, and had incomes less than 200% of the national poverty level. Healthcare utilization, defined as physician visits and general healthcare visits. Illness mediated the effect of psychosocial vulnerability on healthcare utilization for African Americans and Euro-Americans. The model for Mexican Americans was the most complex. Psychosocial vulnerability on illness was partially mediated by barriers, which also directly affected utilization. Psychosocial vulnerabilities were significant utilization predictors for healthcare use for all low-income women in this study. The final models for the 2 minority groups, African Americans and Mexican Americans, were quite different. Hence, women of color should not be considered a homogeneous group in comparison to Euro-Americans.

2008-10-01

Multi-period differences of technical and financial performances are analysed by comparing five North African railways over the period (1990-2004). A first approach is based on the Malmquist DEA TFP index for measuring the total factors productivity change, decomposed into technical efficiency change and technological changes. A multiple criteria analysis is also performed using the PROMETHEE II method and the software ARGOS. These methods provide complementary detailed information, especially by discriminating the technological and management progresses by Malmquist and the two dimensions of performance by Promethee: that are the service to the community and the enterprises performances, often in conflict.

Racial/Ethnic Differences in the Relationship Between Neighborhood Disadvantage and Adolescent Substance Use.

Fagan, Abigail A; Wright, Emily M; Pinchevsky, Gillian M

2013-01-01

Although social disorganization theory hypothesizes that neighborhood characteristics influence youth delinquency, the impact of neighborhood disadvantage on adolescent substance use and racial/ethnic differences in this relationship have not been widely investigated. The present study examines these issues using longitudinal data from 1,856 African American, Hispanic, and Caucasian adolescents participating in the Project on Human Development in Chicago Neighborhoods (PHDCN). The results indicated that neighborhood disadvantage did not significantly increase the likelihood of substance use for the full sample. When relationships were analyzed by race/ethnicity, one significant ( p ≤ .10) effect was found; disadvantage increased alcohol use among African Americans only. The size of this effect differed significantly between African American and Hispanic youth. In no other cases did race/ethnicity moderate the impact of disadvantage on substance use. These results suggest that disadvantage is not a strong predictor of adolescent substance use, although other features of the neighborhood may affect such behaviors.

Using genome-wide genotypes, we characterized the genetic structure of 103,006 participants in the Kaiser Permanente Northern California multi-ethnic Genetic Epidemiology Research on Adult Health and Aging Cohort and analyzed the relationship to self-reported race/ethnicity. Participants endorsed any of 23 race/ethnicity/nationality categories, which were collapsed into seven major race/ethnicity groups. By self-report the cohort is 80.8% white and 19.2% minority; 93.8% endorsed a single race/ethnicity group, while 6.2% endorsed two or more. Principal component (PC) and admixture analyses were generally consistent with prior studies. Approximately 17% of subjects had genetic ancestry from more than one continent, and 12% were genetically admixed, considering only nonadjacent geographical origins. Self-reported whites were spread on a continuum along the first two PCs, indicating extensive mixing among European nationalities. Self-identified East Asian nationalities correlated with genetic clustering, consistent with extensive endogamy. Individuals of mixed East Asian–European genetic ancestry were easily identified; we also observed a modest amount of European genetic ancestry in individuals self-identified as Filipinos. Self-reported African Americans and Latinos showed extensive European and African genetic ancestry, and Native American genetic ancestry for the latter. Among 3741 genetically identified parent–child pairs, 93% were concordant for self-reported race/ethnicity; among 2018 genetically identified full-sib pairs, 96% were concordant; the lower rate for parent–child pairs was largely due to intermarriage. The parent–child pairs revealed a trend toward increasing exogamy over time; the presence in the cohort of individuals endorsing multiple race/ethnicity categories creates interesting challenges and future opportunities for genetic epidemiologic studies.

Full Text Available The rise in African immigrants to the US provides an opportunity to assess relations between Africans and African Americans in college. An online survey of 322 current and recently-graduated college students (including 45 Africans, 160 African Americans, and 117 whites assessed respondents’ experiences of racism in US high schools and colleges. Semi-structured interviews of 30 students (10 African, 10 African American and 10 white students supplemented these data. Even within a sociopolitical context of more visible racial intolerance, Black intra-racial cohesion was absent. Although more first- and second-generation Africans (73% felt that they had been judged while living in the US compared to African Americans (34% or whites (20%, for 70–80% of respondents, this had occurred only in high school. Despite experiencing these judgments, Africans’ identity related more to their focus on education than their race, reflected in a higher proportion who felt intense family pressure to attend college (65% compared to African Americans (37% and whites (39%. Interview data confirmed previous reports in the literature that African Americans lack a sense of connection to Africans, attributed to Africans’ purported sense of superiority and disregard for African Americans’ ongoing struggle to end oppression. These mixed-methods data suggest that intermingling in the college environment has not resulted in first- and second-generation Africans and African Americans sharing a common in-group, race-based identity. We discuss the implications of overlooking ethnic distinctions due to presumptions of racial homogeneity that deprive Black individuals of their uniqueness.

Full Text Available Two adipokines (adiponectin and resistin have opposite relations with insulin resistance and inflammation. Our major focus was to determine whether there were detectable ethnic differences in maternal adipokines during pregnancy. We also explored the correlation of the adipokines with maternal glucose homeostasis, blood pressure and anthropometric parameters. Pregnant women (n = 1634 were from a large prospective cohort study in Camden NJ (African-American 36.8%; Hispanic 47.6%; Caucasian 15.6%. Serum adiponectin and resistin were measured at entry (week 16.8 and the 3rd trimester (week 30.7 using the Luminex xMapTechnology. Significant differences were observed among ethnic groups, controlling for confounding variables. African American women were exceptional in that they had decreased adiponectin and increased resistin throughout the course of pregnancy (p < 0.05 to p < 0.0001 and a greater than two fold risk of simultaneously exhibiting low adiponectin (lowest tertile and high resistin (highest tertile compared to Caucasians and/or Hispanics. The cohort as a whole and each ethnic group showed similar negative correlations between adiponectin, and glucose homeostasis, blood pressure and anthropometric parameters but there was lesser correspondence with resistin. Our data underscore the need for further research on ethnic variation in adipokines and other physiologic biomarkers during complicated and uncomplicated pregnancy.

5-HTTLPR Polymorphism: Analysis in South African Autistic Individuals

KAUST Repository

Arieff, Zainunisha

2010-06-01

The serotonin transporter promoter length polymorphism (5-hydroxytryptamine transporter length polymorphism; 5-HTTLPR) has long been implicated in autism and other psychiatric disorders. The use of selective serotonin reuptake inhibitors (SSRIs) has a positive effect on treating some symptoms of autism. The effects of these drugs vary in individuals because of the presence of the S or L allele of 5-HTTLPR. Studies performed on various autistic populations have found different allele frequencies for the L and S alleles. Allele frequencies and genotypes of the South African autistic populations (African, mixed, and Caucasian) were compared with matching South African ethnic control populations. The *S/*S genotype was found to be highly significantly associated with all the South African autistic ethnic populations. In the South African African population the *S/*S genotype was present in 7 (33%) of the autistic individuals but in none of the control subjects, yielding infinitely large odds of developing autism. The odds of developing autism with the *S/*S genotype compared to the *L/*L genotype increased 10.15-fold in the South African mixed group and 2.74-fold in the South African Caucasian population. The allele frequency of the South African autistic population was also compared with studies of other autistic populations around the world, and highly significant differences were found with the Japanese, Korean, and Indian population groups. The difference was not significant for the French, German, Israeli, Portuguese, and American groups. This is the first South African study of autistic individuals of different ethnic backgrounds that shows significant differences in allele and genotype frequencies of 5-HTTLPR. The results of this study open new avenues for investigating the role of transmission of the L and S alleles in families with autism in South Africa.

Persistent tobacco use among racial and ethnic minority populations in the United States is a critical public health concern. Yet, potential sources of racial/ethnic disparities in tobacco use remain unclear. The present study examined racial/ethnic differences in tobacco withdrawal-a clinically-relevant underpinning of tobacco use that has received sparse attention in the disparities literature-utilizing a controlled laboratory design. Daily smokers (non-Hispanic African American [n = 178], non-Hispanic white [n = 118], and Hispanic [n = 28]) attended two counterbalanced sessions (non-abstinent vs. 16-hour abstinent). At both sessions, self-report measures of urge, nicotine withdrawal, and affect were administered and performance on an objective behavioral task that assessed motivation to reinstate smoking was recorded. Abstinence-induced changes (abstinent scores vs. non-abstinent scores) were analyzed as a function of race/ethnicity. Non-Hispanic African American smokers reported greater abstinence-induced declines in several positive affect states in comparison to other racial/ethnic groups. Relative to Hispanic smokers, non-Hispanic African American and non-Hispanic white smokers displayed larger abstinence-provoked increases in urges to smoke. No racial/ethnic differences were detected for a composite measure of nicotine withdrawal symptomatology, negative affect states, and motivation to reinstate smoking behavior. These results suggest qualitative differences in the expression of some components of tobacco withdrawal across three racial/ethnic groups. This research helps shed light on bio-behavioral sources of tobacco-related health disparities, informs the application of smoking cessation interventions across racial/ethnic groups, and may ultimately aid the overall effort towards reducing the public health burden of tobacco addiction in minority populations. The current study provides some initial evidence that there may be qualitative differences in the

Maternal race/ethnicity and maternal body mass index (BMI) were the key exposures; their independent and joint impact on outcomes using regression models was analyzed. Racial/ethnic minority women of normal weight generally had higher risk as compared with white women of normal weight (e.g., African-American women, pre-eclampsia adjusted odds ratio [aOR] 1.60, 95% confidence interval [CI]: 1.48-1.74 vs. white women). However, elevated BMI did not usually confer additional risk (e.g., pre-eclampsia aOR comparing African-American women with excess weight with white women with excess weight, 1.17, 95% CI: 0.89-1.54). Obesity was a risk factor for low birth weight only among white women (excess weight aOR, 1.24, 95% CI: 1.04-1.49 vs. white women of normal weight) and not among racial/ethnic minority women (e.g., African-American women, 0.95, 95% CI: 0.83-1.08). These findings add nuance to our understanding of the interplay between maternal race/ethnicity, BMI, and perinatal outcomes. While the BMI/adverse outcome gradient appears weaker in racial/ethnic minority women, this reflects the overall risk increase in racial/ethnic minority women of all body sizes. © 2016 The Obesity Society.

2017-01-01

In this study, we compared 10 ethnic groups for associations between psychiatric disorders and physical self-rated health (SRH) in the United States. Data came from the Collaborative Psychiatric Epidemiology Surveys (CPES), 2001–2003. The study included 7587 non-Latino White, 4746 African American, 1442 Mexican, 1106 other Hispanic, 656 other Asian, 600 Chinese, 577 Cuban, 520 Vietnamese, 508 Filipino, and 495 Puerto Rican individuals. The Composite International Diagnostic Interview (CIDI) was used to measure psychiatric disorders, including major depressive disorder (MDD), general anxiety disorder (GAD), social phobia, panic disorder, post-traumatic stress disorder (PTSD), alcohol abuse, and binge eating disorders. A single-item measure was used to estimate physical SRH. Demographic (age and gender) and socioeconomic (education and income) factors were also measured. Unadjusted and adjusted correlations between psychiatric disorders and physical SRH were calculated. Major ethnic variations were found in the correlation between psychiatric disorders and physical SRH; as well as the role of demographic and socioeconomic status (SES) factors in explaining these associations. non-Hispanic Whites, Cubans, and African Americans showed more correlations between psychiatric disorders and physical SRH than other ethnic groups. In non-Hispanic Whites, the associations between psychiatric disorders and physical SRH were explained by demographic factors. In African Americans, the link between psychiatric disorders and poor physical SRH were explained by SES indicators. In conclusion, although single-item physical SRH measures are traditionally assumed to reflect the physical health needs of populations, they may also indicate psychiatric disorders in some ethnic groups, such as non-Hispanic Whites, Cubans, and African Americans. Demographic and socioeconomic factors also have differential roles in explaining the link between psychiatric disorders and physical SRH. Physical

Sexual health entails the absence of disease and the ability to lead a pleasurable and safe sex life. In Britain, ethnic inequalities in diagnoses of sexually transmitted infections (STI) persist; however, the reasons for these inequalities, and ethnic variations in other markers of sexual health, remain poorly understood. We investigated ethnic differences in hypothesised explanatory factors such as socioeconomic factors, substance use, depression, and sexual behaviours, and whether they explained ethnic variations in sexual health markers (reported STI diagnoses, attendance at sexual health clinics, use of emergency contraception, and sexual function). We analysed probability survey data from Britain's third National Survey of Sexual Attitudes and Lifestyles (Natsal-3; n=15 162, conducted in 2010-12). Reflecting Britain's current ethnic composition, we included in our analysis participants who identified in 2011 as belonging to one of the following seven largest ethnic groups: white British, black Caribbean, black African, Indian, Pakistani, white other, and mixed ethnicity. We calculated age-standardised estimates and age-adjusted odds ratios for all explanatory factors and sexual health markers for all these ethnic groups with white British as the reference category. We used multivariable regression to examine the extent to which adjusting for explanatory factors explained ethnic variations in sexual health markers. We included 14 563 (96·0%) of the 15 162 participants surveyed in Natsal-3. Greater proportions of black Caribbean, black African, and Pakistani people lived in deprived areas than those of other ethnic groups (36·9-55·3% vs 16·4-29·4%). Recreational drug use was highest among white other and mixed ethnicity groups (25·6-27·7% in men and 10·3-12·9% in women in the white other and mixed ethnicity groups vs 4·1-15·6% in men and 1·0-11·2% in women of other ethnicities). Compared with white British men, the proportions of black

Perceived Discrimination and Suicide Ideation: Moderating Roles of Anxiety Symptoms and Ethnic Identity among Asian American, African American, and Hispanic Emerging Adults.

Suicide is a leading cause of death for vulnerable ethnic minority emerging adults in the United States (Web-based injury statistics query and reporting system [WISQARS], 2015). Perceived discrimination (Journal of Youth and Adolescence, 40, 2011, 1465) and anxiety symptoms (Asian American Journal of Psychology, 1, 2010, 18) are two predictors that are theoretically and conceptually related, but have yet to be examined in a simultaneous model for suicide ideation. Existing theory and research suggest that these variables activate similar pathways (American Behavioral Scientist, 51, 2007, 551). This study sought to address this gap in the literature by examining the simultaneous relationship between perceived discrimination and anxiety symptoms as predictors of suicide ideation. The moderating effect of anxiety symptoms on the relationship between perceived discrimination and suicide ideation was examined in a multiethnic sample of emerging adults. Results indicated that anxiety symptoms moderated the perceived discrimination-suicide ideation relationship for Hispanic emerging adults, but not for their Asian American and African American counterparts. Furthermore, ethnic identity has been shown to mitigate suicide risk in the face of other stressors (Cultural Diversity and Ethnic Minority Psychology, 14, 2008, 75). Ethnic identity emerged as a protective factor for Hispanic emerging adults by further interacting with perceived discrimination and anxiety symptoms to negatively predict suicide ideation. The implications of these findings are discussed. © 2018 The American Association of Suicidology.

The applicability of the recent multi-ethnic reference equations derived by the ERS Global Lung Initiative (ERS/GLI) in interpreting spirometry data in North African adult subjects has not been studied. To ascertain how well the recent ERS/GLI reference equations fit contemporary adult Tunisian spirometric data. Spirometric data were recorded from 1192 consecutive spirometry procedures in adults aged 18-60 years. Reference values and lower limits of normality (LLN) were calculated using the local and the ERS/GLI reference equations. Applied definitions: large airway obstructive ventilatory defect (LAOVD): FEV1/FVC contemporary Tunisian spirometry. Using Tunisian reference equations, 71.31%, 6.71% and 19.04% of spirometry records were interpreted as normal, and as having, LAOVD and TRVD, respectively. Using the ERS/GLI reference equations, these figures were respectively, 85.82%, 4.19% and 8.39%. The mean ± SD Z-scores for the contemporary healthy North African subject's data were -0.55 ± 0.87 for FEV1, -0.62 ± 0.86 for FVC and 0.10 ± 0.73 for FEV1/FVC. The present study don't recommend the use of the recent ERS/GLI reference equations to interpret spirometry in North African adult population. Copyright © 2013 Elsevier Ltd. All rights reserved.

This study aimed to investigate the association between obesity and major depression disorder (MDD) in a nationally representative sample of Black adolescents in the USA. The study also tested the effects of ethnicity and gender as possible moderators. Data came from the National Survey of American Life (NSAL)-Adolescents, a representative household mental health survey of Black adolescents in the USA. Participants consisted of 1170 Black adolescents (810 African Americans and 360 Caribbean Blacks). Obesity was defined determined by the cutoff points based on the body mass index (BMI) appropriate for age and gender. Twelve-month MDD was measured using the World Mental Health Composite International Diagnostic Interview (CIDI). In the first step, the association between obesity and MDD in the pooled sample, controlling for the main effects of gender and ethnicity. In the next steps, two interactions were tested: (1) obesity and ethnicity and (2) obesity and gender. Although any associations between obesity and MDD in the pooled sample of Blacks were not found, there was a significant interaction between ethnicity and obesity on MDD. Upon testing the associations across intersections of ethnicity and gender, a positive association was found among Caribbean Black females but not Caribbean Black males, African American males, or African American female. The link between BMI and MDD among Blacks depends on ethnicity and gender, and risk of comorbid depression among Black youth with obesity is highest among Caribbean Black females.

Objective To identify ethnic differences in HIV risk behaviors among cocaine using women receiving methadone maintenance for opioid dependence, and to evaluate the efficacy of contingency management (CM) for cocaine use disorders in reducing HIV risk behaviors. Methods African American (N=47), Hispanic (N=47), and White women (N = 29) were randomized to standard methadone treatment or standard methadone treatment plus a CM intervention. They completed the HIV Risk Behavior Scale (HRBS) indicating frequency of drug use and sexual behaviors across the lifetime, in the month before baseline, and in the 3 months following clinical trial participation. Ethnic group differences and the effect of CM on change in HIV risk behaviors between baseline and follow-up were evaluated. Results White women reported significantly higher lifetime rates of risky drug use and sexual behaviors on the HRBS than African American women; neither group differed significantly from Hispanic women. No ethnic group differences in HIV risk behaviors were identified in the month prior to baseline. At follow-up, African American women reported fewer high-risk drug use behaviors than White or Hispanic women, and Hispanic women reported more high-risk sexual behaviors than White or African American women. CM was associated with reduction in high-risk drug use behaviors regardless of ethnicity, but did not affect high-risk sexual behaviors. Conclusions White women receiving methadone maintenance engage in more lifetime HIV risk behaviors than African American women. CM for cocaine use reduces risky drug use behaviors, but certain ethnic groups may benefit from additional targeted HIV prevention efforts. PMID:18684571

Discrimination is associated with obesity, but this may differ according to the type of obesity and ethnic group. This study examines the association of perceived ethnic discrimination (PED) with general and abdominal obesity in 5 ethnic minority groups. We used cross-sectional data from the HELIUS study, collected from 2011 to 2015. The study sample included 2297 Ghanaians, 4110 African Surinamese, 3021 South-Asian Surinamese, 3562 Turks and 3868 Moroccans aged 18-70 years residing in Amsterdam, the Netherlands. Body mass index (BMI) was used as a measure for general obesity, and waist circumference (WC) for abdominal obesity. PED was measured using the Everyday Discrimination Scale. We used linear regression models adjusted for sociodemographics, psychosocial stressors and health behaviours. In additional analysis, we used standardised variables to compare the strength of the associations. In adjusted models, PED was significantly, positively associated with BMI in the South-Asian Surinamese (β coefficient 0.338; 95% CI 0.106 to 0.570), African Surinamese (0.394; 0.171 to 0.618) and Turks (0.269; 0.027 to 0.510). For WC, a similar pattern was seen: positive associations in the South-Asian Surinamese (0.759; 0.166 to 1.353), African Surinamese (0.833; 0.278 to 1.388) and Turks (0.870; 0.299 to 1.440). When stratified by sex, we found positive associations in Surinamese women, Turkish men and Moroccan men. The strength of the associations with BMI and WC was comparable in the groups. Among the Ghanaians, no significant associations were observed. Ethnic and sex variations are observed in the association of PED with both general and abdominal obesity. Further research on psychosocial buffers and underlying biological mechanisms might help in understanding these variations. Published by the BMJ Publishing Group Limited.

Little is known about racial and ethnic disparities in health care utilization, expenditures and drug choice in the antidepressant market. This study investigates factors associated with the racial and ethnic disparities in antidepressant drug use. We seek to determine the extent to which disparities reflect differences in observable population characteristics versus heterogeneity across racial and ethnic groups. Among the population characteristics, we are interested in identifying which factors are most important in accounting for racial and ethnic disparities in antidepressant drug use. Using Medical Expenditure Panel Survey (MEPS) data from 1996-2003, we have an available sample of 10,416 Caucasian, 1,089 African American and 1,539 Hispanic antidepressant drug users aged 18 to 64 years. We estimate individual out-of-pocket payments, total prescription drug expenditures, drug utilization, the probability of taking generic versus brand name antidepressants, and the share of drugs that are older types of antidepressants (e.g., TCAs and MAOIs) for these individuals during a calendar year. Blinder-Oaxaca decomposition techniques are employed to determine the extent to which disparities reflect differences in observable population characteristics versus unobserved heterogeneity across racial and ethnic groups. Caucasians have the highest antidepressant drug expenditures and utilization. African-Americans have the lowest drug expenditures and Hispanics have the lowest drug utilization. Relative to Caucasians and Hispanics, African-Americans are more likely to purchase generics and use a higher share of older drugs (e.g., TCAs and MAOIs). Differences in observable characteristics explain most of the racial/ethnic differences in these outcomes, with the exception of drug utilization. Differences in health insurance and education levels are particularly important factors in explaining disparities. In contrast, differences in drug utilization largely reflect unobserved

Age and ethnicity differences in storytelling to young children: emotionality, relationality, and socialization.

2002-12-01

Research has shown that age and ethnicity are associated with individuals' motivations for emotional regulation and social interaction. The authors proposed that these age and ethnicity-related motives would be reflected in storytelling. Women representing 2 age and 2 ethnic groups (young adulthood, oldage, African American, European American) told stories to young girls. Stories were coded for emotional, relational, and socialization focus. They predicted that older adults would selectively emphasize positive over negative emotions and would direct more utterances toward their interaction with their listener. The authors expected that African Americans would be more likely to emphasize socialization themes. Results suggest that older adults positively modulate emotional content while storytelling; qualified support was found for hypotheses concerning socialization and interrelational emphasis.

Previous work showed high agreement in facial attractiveness preferences within and across cultures. The aims of the current study were twofold. First, we tested cross-cultural agreement in the attractiveness judgements of White Scottish and Black South African students for own- and other-ethnicity faces. Results showed significant agreement between White Scottish and Black South African observers' attractiveness judgements, providing further evidence of strong cross-cultural agreement in facial attractiveness preferences. Second, we tested whether cross-cultural agreement is influenced by the ethnicity and/or the gender of the target group. White Scottish and Black South African observers showed significantly higher agreement for Scottish than for African faces, presumably because both groups are familiar with White European facial features, but the Scottish group are less familiar with Black African facial features. Further work investigating this discordance in cross-cultural attractiveness preferences for African faces show that Black South African observers rely more heavily on colour cues when judging African female faces for attractiveness, while White Scottish observers rely more heavily on shape cues. Results also show higher cross-cultural agreement for female, compared to male faces, albeit not significantly higher. The findings shed new light on the factors that influence cross-cultural agreement in attractiveness preferences. PMID:24988325

Holliday, Bertha Garrett

2009-10-01

The author describes the multiple pathways of events and strategies that served to nurture African American psychology in the United States. Special attention is given to strategies for inclusion and empowerment used in 4 psychological professional and scholarly associations: the American Counseling Association, the American Psychological Association, the Association of Black Psychologists, and the Society for Research in Child Development. In addition, the author describes 4 major intellectual traditions that informed not only the strategies of inclusion but also the theoretical, research, and intervention perspectives and other professional and academic efforts of African American psychologists. Those perspectives are the Afrocentric/African-centered tradition derived from longstanding nationalist/Pan-African and culturally centered traditions within African American communities; the social contextual/multidisciplinary research tradition of the University of Chicago School of Social Science; the empirical social science research tradition of the University of Michigan; and the Black scholar/activist tradition of Howard University. This article also presents a chronological timeline of major events in the history of African American psychology. Copyright 2009 APA, all rights reserved.

Absence of Multiple Sclerosis and Demyelinating Diseases among Lacandonians, a Pure Amerindian Ethnic Group in Mexico

2012-01-01

Full Text Available Multiple Sclerosis (MS is a highly polymorphic disease characterized by different neurologic signs and symptoms. In MS, racial and genetic factors may play an important role in the geographic distribution of this disease. Studies have reported the presence of several protective alleles against the development of autoimmune disorders. In the case of MS, however, they help define MS as a complex disease, and confirm the importance of environmental agents as an independent variable not associated with ethnicity. We carried out an on-site epidemiological study to confirm the absence of MS or NMO among Lacandonians, a pure Amerindian ethnic group in Mexico. We administered a structured interview to 5,372 Lacandonians to assess by family background any clinical data consistent with the presence of a prior demyelinating event. Every participating subject underwent a comprehensive neurological examination by a group of three members of the research team with experience in the diagnosis and treatment of demyelinating disorders to detect clinical signs compatible with a demyelinating disease. We did not find any clinical signs compatible with multiple sclerosis among study participants.

Impact of gender and ethnic composition of South African boards of directors on intellectual capital performance

Full Text Available This study examines the association between the gender and ethnic composition of boards of directors and firm performance in a transitional nation. In contrast to prior research that largely focuses on firm performance within a financial context, this study concentrates on intellectual capital performance. Using data collected from 84 South African, empirical results indicate a positive association between the percentage of female and non-white directors on the board and a firm’s intellectual capital performance. Additional analysis shows the designation of female directors as an insider has a negative effect of intellectual capital performance. Designation of female and non-white directors as outsiders, meanwhile, has a positive influence on a firm’s intellectual capital performance. Finally, there was no association between the percentage of non-white inside directors on the board and intellectual capital performance.

The current study utilized the intersectionality framework to explore whether smoking outcome expectancies (i.e., cognitions about the anticipated effects of smoking) were predicted by gender and ethnicity, and the gender-by-ethnicity interaction. In a cross-sectional design, daily smokers from the general community (32.2% women; non-Hispanic African American [n = 175], non-Hispanic White [n = 109], or Hispanic [n = 26]) completed self-report measures on smoking expectancies and other co-factors. Results showed that women reported greater negative reinforcement (i.e., anticipated smoking-induced negative affect reduction) and weight control (i.e., anticipated smoking-induced appetite/weight suppression) expectancies than men. Hispanic (vs. African American or White) smokers endorsed greater negative reinforcement expectancies. A gender-by-ethnicity interaction was found for weight control expectancies, such that White women reported greater weight control expectancies than White men, but no gender differences among African American and Hispanic smokers were found. These findings suggest that gender, ethnicity, and their intersectionality should be considered in research on cognitive mechanisms that may contribute to tobacco-related health disparities. © The Author(s) 2015.

Future Directions in Research on Racism-Related Stress and Racial-Ethnic Protective Factors for Black Youth.

Jones, Shawn C T; Neblett, Enrique W

2017-01-01

Research on racism-related stress and racial-ethnic protective factors represents an important enterprise for optimizing the mental health of African American and other racial and ethnic minority youth. However, there has been a relative dearth of work on these factors in the clinical psychology research literature, and more work is needed in outlets such as these. To this end, the current article adopts a developmental psychopathology framework and uses recent empirical findings to outline our current understanding of racism-related stress and racial-ethnic protective factors (i.e., racial identity, racial socialization, Africentric worldview) for African American youth. We then provide nine recommendations-across basic, applied, and broader/cross-cutting research lines-that we prioritize as essential to advancing the future scientific investigation of this crucial research agenda. Within and across these recommendations, we issue a charge to researchers and clinicians alike, with the ultimate goal of alleviating the negative mental health impact that racism-related stress can have on the well-being and mental health of African American and other racial and ethnic minority youth.

Racial/Ethnic, socioeconomic, and geographic disparities of cervical cancer advanced-stage diagnosis in Texas.

Zhan, F Benjamin; Lin, Yan

2014-01-01

Advanced-stage diagnosis is among the primary causes of mortality among cervical cancer patients. With the wide use of Pap smear screening, cervical cancer advanced-stage diagnosis rates have decreased. However, disparities of advanced-stage diagnosis persist among different population groups. A challenging task in cervical cancer disparity reduction is to identify where underserved population groups are. Based on cervical cancer incidence data between 1995 and 2008, this study investigated advanced-stage cervical cancer disparities in Texas from three social domains: Race/ethnicity, socioeconomic status (SES), and geographic location. Effects of individual and contextual factors, including age, tumor grade, race/ethnicity, as well as contextual SES, spatial access to health care, sociocultural factors, percentage of African Americans, and insurance expenditures, on these disparities were examined using multilevel logistic regressions. Significant variations by race/ethnicity and SES were found in cervical cancer advanced-stage diagnosis. We also found a decline in racial/ethnic disparities of advanced cervical cancer diagnosis rate from 1995 to 2008. However, the progress was slower among African Americans than Hispanics. Geographic disparities could be explained by age, race/ethnicity, SES, and the percentage of African Americans in a census tract. Our findings have important implications for developing effective cervical cancer screening and control programs. We identified the location of underserved populations who need the most assistance with cervical cancer screening. Cervical cancer intervention programs should target Hispanics and African Americans, as well as individuals from communities with lower SES in geographic areas where higher advanced-stage diagnosis rates were identified in this study.

Impaired or excessive fetal growth is associated with adverse short- and long-term health outcomes that differ between ethnic groups. We explored ethnic differences in fetal size and growth from mid pregnancy until birth. Data are from the multi-ethnic STORK-Groruddalen study, a population-based, prospective cohort of 823 pregnant women and their offspring in Oslo, Norway. Measures were z-scores of estimated fetal weight (EFW), head circumference (HC), abdominal circumference (AC) and femur length (FL), in gestational week 24, 32 and 37, measured by ultrasound, and similar measures at birth. Differences in fetal size and growth were assessed using separate Linear Mixed Models including all four time points, with ethnic Europeans as reference. In week 24 South Asian fetuses had smaller AC, but larger FL than Europeans, and slightly lower EFW (-0.17 SD (-0.33, -0.01), p=0.04). Middle East/North African fetuses also had larger FL, but similar AC, and hence slightly higher EFW (0.18 (0.003, 0.36), p=0.05). Both groups had slower growth of AC, FL and EFW from this time until birth, and had -0.61 SD (-0.73, -0.49) and -0.28 SD (-0.41, -0.15) lower birth weight respectively. Ethnic East Asians, on the other hand, were smaller throughout pregnancy and had -0.58 SD (-0.82, -0.34) lower birth weight. Significant ethnic differences remained after adjusting for maternal factors. We observed ethnic differences in fetal size and body proportions already in gestational week 24, and in fetal growth from this time until birth, which were only partly explained by key maternal factors.

Deep sequencing identifies ethnicity-specific bacterial signatures in the oral microbiome.

Directory of Open Access Journals (Sweden)

Matthew R Mason

Full Text Available Oral infections have a strong ethnic predilection; suggesting that ethnicity is a critical determinant of oral microbial colonization. Dental plaque and saliva samples from 192 subjects belonging to four major ethnicities in the United States were analyzed using terminal restriction fragment length polymorphism (t-RFLP and 16S pyrosequencing. Ethnicity-specific clustering of microbial communities was apparent in saliva and subgingival biofilms, and a machine-learning classifier was capable of identifying an individual's ethnicity from subgingival microbial signatures. The classifier identified African Americans with a 100% sensitivity and 74% specificity and Caucasians with a 50% sensitivity and 91% specificity. The data demonstrates a significant association between ethnic affiliation and the composition of the oral microbiome; to the extent that these microbial signatures appear to be capable of discriminating between ethnicities.

The present study examined the relevance of communalism, operationalized as a cultural orientation emphasizing interdependence, to maternal prenatal emotional health and physiology and distinguished its effects from those of ethnicity and childhood and adult SES. African American and European American women (N=297) were recruited early in pregnancy and followed through 32 weeks gestation using interviews and medical chart review. Overall, African American women and women of lower socioeconomic backgrounds had higher levels of negative affect, stress and blood pressure, but these ethnic and socioeconomic disparities were not observed among women higher in communalism. Hierarchical multivariate regression analyses showed that communalism was a more robust predictor of prenatal emotional health than ethnicity, childhood SES, and adult SES. Communalism also interacted with ethnicity and SES, resulting in lower blood pressure during pregnancy for African American women and women who experienced socioeconomic disadvantage over the life course. The effects of communalism on prenatal affect, stress, and physiology were not explained by depressive symptoms at study entry, perceived availability of social support, self-esteem, optimism, mastery, nor pregnancy-specific factors, including whether the pregnancy was planned, desired after conception, or how frequently the woman felt happy to be pregnant. This suggests that a communal cultural orientation benefits maternal prenatal emotional health and physiology over and above its links to better-understood personal and social resources in addition to economic resources. Implications regarding culture as a determinant of maternal prenatal health and well-being and as a potentially important lens for examining ethnic and socioeconomic inequalities in health are discussed.

Memory and executive functioning are two important components of clinical neuropsychological (NP) practice and research. Multiple demographic factors are known to affect performance differentially on most NP tests, but adequate normative corrections, inclusive of race/ethnicity, are not available for many widely used instruments. This study compared demographic contributions for widely used tests of verbal and visual learning and memory (Brief Visual Memory Test-Revised, Hopkins Verbal Memory Test-Revised) and executive functioning (Stroop Color and Word Test, Wisconsin Card Sorting Test-64) in groups of healthy Caucasians (n = 143) and African Americans (n = 103). Demographic factors of age, education, gender, and race/ethnicity were found to be significant factors on some indices of all four tests. The magnitude of demographic contributions (especially age) was greater for African Americans than for Caucasians on most measures. New, demographically corrected T-score formulas were calculated for each race/ethnicity. The rates of NP impairment using previously published normative standards significantly overestimated NP impairment in African Americans. Utilizing the new demographic corrections developed and presented herein, NP impairment rates were comparable between the two race/ethnicities and were unrelated to the other demographic characteristics (age, education, gender) in either race/ethnicity group. Findings support the need to consider extended demographic contributions to neuropsychological test performance in clinical and research settings.

This cross-sectional study examined racial/ethnic differences in meeting the 2008 United States Department of Health and Human Services Physical Activity Guidelines aerobic component (≥150 moderate-to-vigorous minutes/week in bouts of ≥10 minutes) among persons with or at risk of radiographic knee osteoarthritis (RKOA). We evaluated African American versus white differences in guideline attainment using multiple logistic regression, adjusting for sociodemographic (age, sex, site, income, and education) and health factors (comorbidity, depressive symptoms, overweight/obesity, and knee pain). Our analyses included adults ages 49-84 years who participated in accelerometer monitoring at the Osteoarthritis Initiative 48-month visit (n = 1,142 with RKOA and n = 747 at risk of RKOA). Two percent of African Americans and 13.0% of whites met the guidelines. For adults with and at risk of RKOA, significantly lower rates of guidelines attainment among African Americans compared to whites were partially attenuated by health factor differences, particularly overweight/obesity and knee pain (with RKOA: adjusted odds ratio [OR] 0.24, 95% confidence interval [95% CI] 0.08-0.72; at risk of RKOA: OR 0.28, 95% CI 0.07-1.05). Despite known benefits from physical activity, attainment of the physical activity guidelines among persons with and at risk of RKOA was low. African Americans were 72-76% less likely than whites to meet the guidelines. Culturally relevant interventions and environmental strategies in the African American community targeting overweight/obesity and knee pain may reduce future racial/ethnic differences in physical activity and improve health outcomes.

This study examined the association between romanticism (operationalized as mean score on the Romantic Beliefs Scale) and age, sex, and ethnicity in a large community sample (N = 436). Age was negatively correlated with romanticism scores; as age increased, romanticism scores decreased. No sex differences were found; men and women had similar, moderate scores. Although ethnicity largely was unrelated to romanticism, Asian/Pacific Islander participants were significantly more romantic than were African-American participants.

Despite evidence of chemotherapy's ability to cure or comfort those with colon cancer, nearly half of such Americans do not receive it. African Americans (AA) seem particularly disadvantaged. An ethnicity by poverty by health insurance interaction was hypothesized such that the multiplicative disadvantage of being extremely poor and inadequately insured is worse for AAs than for non-Hispanic white Americans (NHWA). California registry data were analyzed for 459 AAs and 3,001 NHWAs diagnosed with stage II to IV colon cancer between 1996 and 2000 and followed until 2011. Socioeconomic data from the 2000 census categorized neighborhoods: extremely poor (≥ 30% of households poor), middle (5-29% poor) and low poverty (Primary health insurers were Medicaid, Medicare, private or none. Chemotherapy rates were age and stage-adjusted and comparisons used standardized rate ratios (RR). Logistic and Cox regressions, respectively, modeled chemotherapy receipt and long term survival. A significant 3-way ethnicity by poverty by health insurance interaction effect on chemotherapy receipt was observed. Among those who did not live in extremely poor neighborhoods and were adequately insured privately or by Medicare, chemotherapy rates did not differ significantly between AAs (37.7%) and NHWAs (39.5%). Among those who lived in extremely poor neighborhoods and were inadequately insured by Medicaid or uninsured, AAs (14.6%) were nearly 60% less likely to receive chemotherapy than were NHWAs (25.5%, RR = 0.41). When the 3-way interaction effect as well as the main effects of poverty, health insurance and chemotherapy was accounted for, survival rates of AAs and NHWAs were the same. The multiplicative barrier to colon cancer care that results from being extremely poor and inadequately insured is worse for AAs than it is for NHWAs. AAs are more prevalently poor, inadequately insured, and have fewer assets so they are probably less able to absorb the indirect and direct, but uncovered

Studies have shown that individuals with intellectual disability (ID) are aware of stigma and are able to describe experiences of being treated negatively. However, there have been no cross-cultural studies examining whether self-reported experiences of stigma vary between ethnic groups. Participants with mild and moderate ID were recruited from a number of different settings in Cape Town, South Africa. Self-reported experiences of stigma in three ethnic groups were measured using the South African version of the Perceived Stigma of Intellectual Disability tool, developed by the authors. One-way anova was used to test whether there were differences in the total stigma score between the ethnic groups. Regression analysis was performed to identify factors associated with stigma. A total of 191 participants agreed to take part; 53 were Black, 70 were of mixed ethnicity and 68 were Caucasian. There were no differences in the levels of stigma reported by the three groups but the Black African ethnic group were more likely to report being physically attacked and being stared at, but were also more likely to report that they thought they were 'the same as other people'. There was an interaction effect between ethnicity and level of ID, with participants with mild ID from the Black African group reporting higher levels of stigma compared with those with moderate ID. Younger age was the only factor that was associated with stigma but there was a trend towards ethnicity, additional disability and socio-economic status being related to stigma. Interventions should target the Black African community in South Africa and should include the reduction of both public stigma and self-reported stigma. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

To investigate whether differences exist in lens position and other lens parameters among major ethnic groups with cataractous eyes, which may help explain racial differences in angle closure risk. This retrospective, cross-sectional study included 807 adult patients who had cataract surgery between years 2014 and 2016 at the University of California, San Francisco (UCSF). Adult patients of white, Asian, Hispanic and African-American ethnicity were included. Lens position (LP), defined as anterior chamber depth (ACD) + 1/2 lens thickness (LT), was assessed using measurements from optical biometry. Other assessed biometric parameters included axial length (AL), relative lens position (RLP) (defined as LP/AL), and anterior chamber depth (ACD). A total of 807 patients and 1361 eyes were included in this study from a database of patients having cataract surgery. Mean age was 69.2 years (age range from 18 to 101 years old), and 60.3% of patients were women. The mean LP measurements were 5.54±0.32 mm for white, 5.38±0.32 mm for Asian, 5.32±0.30 mm for Hispanic, and 5.40±0.28 mm for African-American participants. After adjusting for age, sex, and AL, significant differences were found when comparing LP in paired comparisons among White cohort with Asians (P<0.001), Hispanics (P<0.001) and African-Americans (P = 0.003). Additionally, when comparing RLP, similar significant results were found when comparing Whites with Asians (P<0.001), Hispanics (P<0.001) and African-Americans (P = 0.002). Lastly, pair-wise comparison of LT between ethnic groups showed significant differences while comparing Asians with Whites (P = 0.001) and Asians with African-Americans (P<0.001). The results of this study suggest that the LP of Hispanic, Asian, and African-American patients are significantly smaller than that of White patients, and among all ethnic groups, Hispanics and after Asians have the smallest LP (P<0.001) and RLP (P<0.001). These findings may have implications for the

Trajectories of gender identity were examined from Grade 6 (M age  = 11.9 years) to Grade 9 in European French (n = 570) and North African French (n = 534) adolescents, and gender and ethnic group differences were assessed in these trajectories. In Grade 6, boys of both ethnic groups reported higher levels of gender typicality and felt pressure for gender conformity than girls. European French girls and boys and North African French girls reported decreasing gender typicality from Grade 6 to Grade 9, whereas North African French boys did not change. Felt pressure decreased among girls, did not change in European French boys, and increased in North African French boys. Ethnic and gender differences in gender identity development are discussed. © 2017 The Authors. Child Development © 2017 Society for Research in Child Development, Inc.

Hypertension is a major problem among European ethnic minority groups. We assessed the current situation of hypertension prevalence and its management among a multi-ethnic population in Amsterdam, The Netherlands. Data from the HELIUS study were used including 12,974 participants (1871 Ghanaian, 2184 African Surinamese, 2278 South-Asian Surinamese, 2277 Turkish, 2222 Moroccan and 2142 Dutch origin people), aged 18-70 years. Comparisons among groups were made using proportions and age-adjusted prevalence ratios (PRs). Hypertension prevalence ranged from 24% and 16% in Moroccan men and women to 52% and 62% in Ghanaian men and women. Except for Moroccan women, age-adjusted PR of hypertension was higher in all the ethnic minority groups than in Dutch. Among hypertensives, ethnic minority groups generally had higher levels of hypertension awareness and BP lowering treatment than Dutch. Moreover, prevalence rates for the prescription of more than one BP lowering drug were generally higher in African and South-Asian origin groups compared with Dutch origin people. By contrast, BP control levels were lower in all the ethnic groups than in Dutch, with control rates being significantly lower in Ghanaian men (26%, PR=0.49; 95% CI, 0.37-0.66) and women (45%, PR=0.64; 0.52-0.77), African-Surinamese men (30%, PR=0.61; 0.46-0.81) and women (45%, PR=0.72; 0.51-0.77), and South-Asian Surinamese men (43%, PR=0.77; 0.61-0.97) and women (47%, PR=0.76; 0.63-0.92) compared with Dutch men (53%) and women (61%). Our findings indicate poor BP control in ethnic minority groups despite the high treatment levels. More work is needed to unravel the potential factors contributing to the poor control in order to improve BP control in ethnic minority groups, particularly among African and South-Asian origin groups.

Ethnic differences in physical activity in children in the UK have not been accurately assessed. We made objective measurements of physical activity in 9-10-year-old British children of South Asian, black African-Caribbean and white European origin. Cross-sectional study of urban primary school children (2006-07). Actigraph-GT1M activity monitors were worn by 2071 children during waking hours on at least 1 full day. Ethnic differences in mean daily activity [counts, counts per minute of registered time (CPM) and steps] were adjusted for age, gender, day of week and month. Multilevel modelling allowed for repeated days within individual and clustering within school. In white Europeans, mean daily counts, CPM and mean daily steps were 394,785, 498 and 10,220, respectively. South Asian and black Caribbean children recorded more registered time per day than white Europeans (34 and 36 min, respectively). Compared with white Europeans, South Asians recorded 18 789 fewer counts [95% confidence interval (CI) 6390-31 187], 41 fewer CPM 95% CI 26-57) and 905 fewer steps (95% CI 624-1187). Black African-Caribbeans recorded 25 359 more counts (95% CI 14 273-36 445), and similar CPM, but fewer steps than white Europeans. Girls recorded less activity than boys in all ethnic groups, with 74 782 fewer counts (95% CI 66 665-82 899), 84 fewer CPM (95% CI 74-95) and 1484 fewer steps (95% CI 1301-1668). British South Asian children have lower objectively measured physical activity levels than European whites and black African-Caribbeans.

Psychological stressors can contribute to adverse health outcomes and lead to health disparities. To examine associations among psychological stressors, coping, blood pressure, body mass index, and body fat in ethnic minority women, we conducted a secondary analysis using data from 178 African American and Hispanic/Latina women who completed measures of perceived racial discrimination and stress, coping, blood pressure, and body composition. The mean age of participants was 45.3 (±9.3 years), and most were obese (74.2%) and had prehypertensive systolic blood pressure (125.7 ± 14.6 mmHg). Hierarchical multiple regression models indicated a significant negative relationship between racial discrimination and percent body fat, and positive associations between stress and blood pressure. Coping did not moderate the association between racial discrimination and blood pressure or body composition. Health care providers should consider psychological stressors as underlying causes for hypertension and address tailored stress-reduction coping strategies when treating African American and Hispanic/Latina women with hypertension.

Studies of racial/ethnic variations in stroke rarely consider the South Asian population, one of the fastest growing sub-groups in the United States. This study compared risk factors for stroke among South Asians with those for whites, African-Americans, and Hispanics. Data on 3290 stroke patients were analyzed to examine risk differences among the four racial/ethnic groups. Data on 3290 patients admitted to a regional stroke center were analyzed to examine risk differences for ischemic stroke (including subtypes of small and large vessel disease) among South Asians, whites, African Americans and Hispanics. South Asians were younger and had higher rates of diabetes mellitus, blood pressure, and fasting blood glucose levels than other race/ethnicities. Prevalence of diabetic and antiplatelet medication use, as well as the incidence of small-artery occlusion ischemic stroke was also higher among South Asians. South Asians were almost a decade younger and had comparable socioeconomic levels as whites; however, their stroke risk factors were comparable to that of African Americans and Hispanics. Observed differences in stroke may be explained by dietary and life style choices of South Asian-Americans, risk factors that are potentially modifiable. Future population and epidemiologic studies should consider growing ethnic minority groups in the examination of the nature, outcome, and medical care profiles of stroke.

Computational analysis of candidate disease genes and variants for Salt-sensitive hypertension in indigenous Southern Africans

KAUST Repository

Tiffin, Nicki

2010-09-27

Multiple factors underlie susceptibility to essential hypertension, including a significant genetic and ethnic component, and environmental effects. Blood pressure response of hypertensive individuals to salt is heterogeneous, but salt sensitivity appears more prevalent in people of indigenous African origin. The underlying genetics of salt-sensitive hypertension, however, are poorly understood. In this study, computational methods including text- and data-mining have been used to select and prioritize candidate aetiological genes for salt-sensitive hypertension. Additionally, we have compared allele frequencies and copy number variation for single nucleotide polymorphisms in candidate genes between indigenous Southern African and Caucasian populations, with the aim of identifying candidate genes with significant variability between the population groups: identifying genetic variability between population groups can exploit ethnic differences in disease prevalence to aid with prioritisation of good candidate genes. Our top-ranking candidate genes include parathyroid hormone precursor (PTH) and type-1angiotensin II receptor (AGTR1). We propose that the candidate genes identified in this study warrant further investigation as potential aetiological genes for salt-sensitive hypertension. © 2010 Tiffin et al.

Ogbu’s (1998 Cultural-Ecological Theory of Minority School Performance, a theoretical framework, posits that the manner by which a group achieves minority status, coupled with community and family educational values, impacts academic achievement. Immigrants, voluntary minorities, perform better academically than involuntary minorities (nonimmigrants because they are more accepting of and more likely to adapt to the White middle-class norms upon which schools in the United States are based (Ogbu, 1994, 2004. While the data overall are positive for the sample, when viewed by ethnic group, it was evident the African and Caribbean students are more academically integrated to campus than African American students. The African students, more so than any other ethnic group, are connecting, interacting, and forming relationships with faculty outside of the classroom; conversely, African American students in this study reported having the least amount of effective connections with faculty.

Ethnic differences in cancer symptom awareness and barriers to seeking medical help in the English population are not fully understood. We aimed to quantify these differences, to help develop more effective health campaigns, tailored to the needs of different ethnic groups. Using a large national data set (n=38 492) of cross-sectional surveys that used the Cancer Research UK Cancer Awareness Measure, we examined how cancer symptom awareness and barriers varied by ethnicity, controlling for socio-economic position, age and gender. Data were analysed using multivariable logistic regression. Awareness of cancer symptoms was lower in minority ethnic groups than White participants, with the lowest awareness observed among Bangladeshis and Black Africans. Ethnic minorities were more likely than White British to report barriers to help-seeking. South Asians reported the highest emotional barriers, such as lack of confidence to talk to the doctor, and practical barriers, such as worry about many other things. The Irish were more likely than the White British to report practical barriers, such as being too busy to visit a doctor. White British participants were more likely than any other ethnic group to report that they would feel worried about wasting the doctor's time. Overall, Black Africans had the lowest barriers. All differences were statistically significant (Pcancer symptoms among ethnic minorities. Campaigns should tackle the specific barriers prevalent in each ethnic group.

To describe breast cancer (BC) incidence and mortality by ethnicity in South Africa (SA). Sources of data included the South African National Cancer Registry (NCR) pathology-based reports (1994–2009) and Statistics South Africa (SSA) mortality data (1997–2009). Numbers of cases, age-standardised incidence rates (ASIR) and lifetime risk (LR) were extracted from the NCR database for 1994–2009. Age-specific incidence rates were calculated for five-year age categories. The direct method of standardisation was employed to calculate age-standardised mortality rates (ASMR) using mortality data. Between 1994 and 2009, there were 85 561 female BC. For the Black, Coloured and Asian groups, increases in ASIR and LR were observed between 1994 and 2009. In 2009, the ASIR for the total population, Blacks, Whites, Coloureds and Asians were 26.9, 18.7, 50.2, 40.9 and 51.2 per 100 000, respectively. For Asians, an increase in proportion of BC as a percentage of all female cancers was observed between 1994 and 2002 (11.1%) and continued to increase to 2009 (a further 4.5%). Whites and Asians presented higher incidences of BC at earlier ages compared with Blacks and Coloureds in 2009. In 1998, there were 1618 BC deaths in SA compared with 2784 deaths in 2009. ASMR between 1997 and 2004 increased but stabilised thereafter. This paper demonstrated that SA BC incidence rates are similar to other countries in the region, but lower than other countries with similar health systems. Ethnic differences in BC trends were observed. However, the reasons for observed ethnic differences are unclear. © The Author 2016.

The authors examined the relevance of communalism, operationalized as a cultural orientation emphasizing interdependence, to maternal prenatal emotional health and physiology and distinguished its effects from those of ethnicity and childhood and adult socioeconomic status (SES). African American and European American women (N = 297) were recruited early in pregnancy and followed through 32 weeks gestation using interviews and medical chart review. Overall, African American women and women of lower socioeconomic backgrounds had higher levels of negative affect, stress, and blood pressure, but these ethnic and socioeconomic disparities were not observed among women higher in communalism. Hierarchical multivariate regression analyses showed that communalism was a more robust predictor of prenatal emotional health than ethnicity, childhood SES, and adult SES. Communalism also interacted with ethnicity and SES, resulting in lower blood pressure during pregnancy for African American women and women who experienced socioeconomic disadvantage over the life course. The effects of communalism on prenatal affect, stress, and physiology were not explained by depressive symptoms at study entry, perceived availability of social support, self-esteem, optimism, mastery, nor pregnancy-specific factors, including whether the pregnancy was planned, whether the pregnancy was desired after conception, or how frequently the woman felt happy to be pregnant. This suggests that a communal cultural orientation benefits maternal prenatal emotional health and physiology over and above its links to better understood personal and social resources in addition to economic resources. Implications of culture as a determinant of maternal prenatal health and well-being and an important lens for examining ethnic and socioeconomic inequalities in health are discussed.

Discrimination is related to depression and poor self-esteem among Black men. Poorer self-esteem is also associated with depression. However, there is limited research identifying how self-esteem may mediate the associations between discrimination and depressive symptoms for disparate ethnic groups of Black men. The purpose of this study was to examine ethnic groups as a moderator of the mediating effects of self-esteem on the relationship between discrimination and depressive symptoms among a nationally representative sample of African American (n = 1201) and Afro-Caribbean American men (n = 545) in the National Survey of American Life. Due to cultural socialization differences, we hypothesized that self-esteem would mediate the associations between discrimination and depressive symptoms only for African American men, but not Afro-Caribbean American men. Moderated-mediation regression analyses indicated that the conditional indirect effects of discrimination on depressive symptoms through self-esteem were significant for African American men, but not for Afro-Caribbean men. Our results highlight important ethnic differences among Black men.

Longitudinal measures of blood pressure, height, weight, leg length, smoking, and socioeconomic circumstances were obtained from London, United Kingdom, schoolchildren of White British (n=692), Black Caribbean (n=670), Black African (n=772), Indian (n=384), and Pakistani and Bangladeshi (n=402) ethnicity at 11 to 13 years and 14 to 16 years. Predicted age- and ethnic-specific means of blood pressure, adjusted for anthropometry and social exposures, were derived using mixed models. Among boys, systolic blood pressure did not differ by ethnicity at 12 years, but the greater increase among Black Africans than Whites led to higher systolic blood pressure at 16 years (+2.9 mm Hg). Among girls, ethnic differences in mean systolic blood pressure were not significant at any age, but while systolic blood pressure hardly changed with age among White girls, it increased among Black Caribbeans and Black Africans. Ethnic differences in diastolic blood pressure were more marked than those for systolic blood pressure. Body mass index, height, and leg length were independent predictors of blood pressure, with few ethnic-specific effects. Socioeconomic disadvantage had a disproportionate effect on blood pressure for girls in minority groups. The findings suggest that ethnic divergences in blood pressure begin in adolescence and are particularly striking for boys. They signal the need for early prevention of adverse cardiovascular disease risks in later life.

The purpose of this study was to examine the associations between perceived ethnic discrimination and (physical and mental) health indicators among North African women and men living in France. This study included 82 North Africans, aged 18-64 years. Perceived discrimination was measured at both group level (PGD) and personal level (PPD). The physical health indicator was blood pressure. The mental health indicator was self-reported psychological distress. Multiple regression analyses showed that higher levels of PGD predicted higher blood pressure. PPD was not related to blood pressure. PPD was positively related to psychological distress among women, but not among men. PPD and PGD are associated with physical and mental health indicators in different ways among North African women and men in France. © 2017 Wiley Periodicals, Inc.

This study examines whether race/ethnicity moderates relationships of (a) diabetes stress and general life stressors with (b) diabetes outcomes of glycemic control and diabetic ketoacidosis (DKA) among emerging adults (aged 18-25 years) with type 1 diabetes (T1D). Using a T1D Exchange Registry sample of non-Hispanic White, African American, and Hispanic emerging adults (N = 3,440), multiple group analyses were used to determine whether race/ethnicity moderates the relationships between stress and diabetes outcomes. The relationships between the two stress types and glycemic control did not differ between African American and non-Hispanic Whites. However, as compared with non-Hispanic Whites, the association between higher diabetes-specific stress and poorer glycemic control was significantly stronger for Hispanics, and Hispanics had poorer glycemic control when they experienced a relatively fewer number of general life stressors than non-Hispanic Whites. The relationships between the type of stress (diabetes-specific and general stress) and DKA did not differ across racial/ethnic groups. Future research should evaluate possible mechanisms that contribute to the different relationships of stress with glycemic control among Hispanics compared with non-Hispanic Whites. © The Author 2017.

Risk factors for acute stroke among South Asians compared to other racial/ethnic groups.

Directory of Open Access Journals (Sweden)

Tefera Gezmu

Full Text Available BACKGROUND: Studies of racial/ethnic variations in stroke rarely consider the South Asian population, one of the fastest growing sub-groups in the United States. This study compared risk factors for stroke among South Asians with those for whites, African-Americans, and Hispanics. METHODS: Data on 3290 stroke patients were analyzed to examine risk differences among the four racial/ethnic groups. Data on 3290 patients admitted to a regional stroke center were analyzed to examine risk differences for ischemic stroke (including subtypes of small and large vessel disease among South Asians, whites, African Americans and Hispanics. RESULTS: South Asians were younger and had higher rates of diabetes mellitus, blood pressure, and fasting blood glucose levels than other race/ethnicities. Prevalence of diabetic and antiplatelet medication use, as well as the incidence of small-artery occlusion ischemic stroke was also higher among South Asians. South Asians were almost a decade younger and had comparable socioeconomic levels as whites; however, their stroke risk factors were comparable to that of African Americans and Hispanics. DISCUSSION: Observed differences in stroke may be explained by dietary and life style choices of South Asian-Americans, risk factors that are potentially modifiable. Future population and epidemiologic studies should consider growing ethnic minority groups in the examination of the nature, outcome, and medical care profiles of stroke.

Distress is a modifiable risk factor for smoking maintenance. This study aimed to assess racial/ethnic differences in distress pre- and post-cognitive-behavioral therapy (CBT) for smoking cessation, and relations with abstinence. Analyses of variance and logistic regressions were conducted. University-based smoking cessation laboratory in South Florida, USA. The sample comprised 234 treatment-seekers recruited from the community (18% white, 60% African American and 22% Hispanic). All participants received eight sessions of group CBT plus 8 weeks of transdermal nicotine patches (TNP). Demographics and smoking history [baseline], perceived stress and depressive symptoms [baseline and end of therapy (EOT)], carbon monoxide-verified 7-day point prevalence abstinence (p.p.a.) at EOT, 3 months post-CBT (primary outcome) and 6 months (self-report). Compared with whites, African Americans reported greater baseline perceived stress (P = 0.03) and depressive symptoms (P = 0.06); no EOT differences were found. African Americans (P perceived stress reduction, and African Americans reported greater reductions in depressive symptoms (P perceived stress (adjusted odds ratio (AOR) = 0.93 (0.89-0.98)) and depressive symptoms [AOR = 0.96 (0.93-0.99)] were associated inversely with 7-day p.p.a. at 3 months. Reductions in perceived stress [AOR = 0.93 (0.89-0.98)] and depressive symptoms at the EOT [AOR = 0.96 (0.93-0.99)] were associated with cessation, such that reduced distress increased the odds of abstinence. The interactions between race/ethnicity and distress on 7-day p.p.a. were not significant at any assessment point. Among smokers in Florida, USA, racial/ethnic differences in distress before starting cognitive-behavioral therapy for smoking cessation were eliminated at the end of treatment, driven by improvements among African Americans and Hispanics. High levels of distress were associated with reduced odds of abstinence through 6�

Assari, Shervin; Caldwell, Cleopatra Howard

2017-05-12

Most studies on the role of family environment in developing risk of obesity among youth have focused on parenting behaviors that are directly involved in energy balance in regional, non-representative White samples. Using a national sample of ethnically diverse Black youth, the current study tested the association between low family support and risk of obesity. We also tested the heterogeneity of this association based on gender, ethnicity, and their intersection. We used data from the National Survey of American Life-Adolescent Supplement (NSAL-A), a national survey of Black adolescents in the United States. The study enrolled 1170 African American and Caribbean Black 13-17 year old youth. Obesity was defined based on the cutoff points of body mass index (BMI) appropriate for age and gender of youth. Family support was measured using a five-item measure that captured emotional and tangible social support. Age, gender, and ethnicity were also measured. Logistic regressions were utilized in the pooled sample, and also based on gender, ethnicity, and their intersection, to test the link between low family support and risk for obesity. In the pooled sample, low family support was not associated with an increased risk of obesity (OR = 1.35, 95% Confidence Interval (CI) = 0.96-1.89). The association between low family support and risk of obesity was, however, significant among African American females (OR = 1.60, 95% CI = 1.01-2.55). There was no association for African American males (OR = 1.26, 95% CI = 0.82-1.92), Caribbean Black males (OR = 0.68, 95% CI = 0.01-54.85), and Caribbean Black females (OR = 0.78, 95% CI = 0.42-1.44). In conclusion, policies and programs that enable African American families to provide additional family support may prevent obesity among African American female youth. Future research should test the efficacy of promoting family support as a tool for preventing obesity among African American female youth.

The aetiology of urological cancers is poorly understood and variations in incidence by ethnic group may provide insights into the relative importance of genetic and environmental risk factors. Our objective was to compare the incidence of four urological cancers (kidney, bladder, prostate and testicular) among six 'non-White' ethnic groups in England (Indian, Pakistani, Bangladeshi, Black African, Black Caribbean and Chinese) to each other and to Whites. We obtained Information on ethnicity for all urological cancer registrations from 2001 to 2007 (n = 329,524) by linkage to the Hospital Episodes Statistics database. We calculated incidence rate ratios adjusted for age, sex and income, comparing the six ethnic groups (and combined 'South Asian' and 'Black' groups) to Whites and to each other. There were significant differences in the incidence of all four cancers between the ethnic groups (all p ethnicity, including within groups that have traditionally been analysed together (South Asians and Blacks). In general, these differences are not readily explained by known risk factors, although the very high incidence of prostate cancer in both black Africans and Caribbeans suggests increased genetic susceptibility. g.

To describe and understand variations in cigarette brand preferences between adolescents from varying ethnic and gender groups around the US. A qualitative study where adolescents, both smokers and nonsmokers, were interviewed individually in depth. Schools and recreation centers in four sites: urban Maryland (Baltimore), urban Texas (Houston), rural Alabama and rural New Mexico. 121 adolescent volunteers 13-19 years of age, representing African American, white, American Indian and Hispanic ethnic groups, from both genders. Considerable geographic and ethnic variation exists in terminology used by youth to refer to cigarettes and to their use. Clear patterns in brand preference by ethnic group were found that follow patterns of targeted marketing by ethnicity. White teens preferred Marlboro brand cigarettes, while African-American teens who smoke preferred Newports. Hispanic and American Indian teens were more likely to smoke Marlboro or Camel cigarettes. Hispanic teens were most likely to mention low price as a reason for choosing a particular brand or to state that the brand does not matter. Tobacco advertisements targeting ethnic groups and the use of promotional items to encourage teen smoking were also recognized as factors influencing brand preferences. These findings have implications for the design of intervention programs aimed at curbing teen smoking. When working with teens who already smoke, using youth language to target messages at perceived characteristics of commonly used brands may be more effective and meaningful than talking about cigarette use in general. Another implication of this work is to shed light on what impact an advertising ban would have on teen brand preferences, brand loyalty, and prevalence of smoking.

Preventing alcohol-related harms, including those causing liver disease, is a public health priority in the UK, especially in Scotland, but the effects of ethnicity are not known. We assessed liver- and alcohol-related events (hospitalisations and deaths) in Scotland using self-reported measures of ethnicity. Linking Scottish NHS hospital admissions and mortality to the Scottish Census 2001, we explored ethnic differences in hospitalisations and mortality (2001-2010) of all liver diseases, alcoholic liver disease (ALD) and specific alcohol-related diseases (ARD). Risk ratios (RR) were calculated using Poisson regression with robust variance, by sex, adjusted for age, country of birth and the Scottish Index of Multiple Deprivation (SIMD) presented below. The White Scottish population was the standard reference population with 95% confidence intervals (CI) calculated to enable comparison (multiplied by 100 for results). For all liver diseases, Chinese had around 50% higher risks for men (RR 162; 95% CI 127-207) and women (141; 109-184), as did Other South Asian men (144; 104-201) and Pakistani women (140; 116-168). Lower risks for all liver diseases occurred in African origin men (42; 24-74), other White British men (72; 63-82) and women (80; 70-90) and other White women (80; 67-94). For ALD, White Irish had a 75% higher risk for men (175; 107-287). Other White British men had about a third lower risk of ALD (63; 50-78), as did Pakistani men (65; 42-99). For ARD, almost 2-fold higher risks existed for White Irish men (182; 161-206) and Any Mixed Background women (199; 152-261). Lower risks of ARD existed in Pakistani men (67; 55-80) and women (48; 33-70), and Chinese men (55; 41-73) and women (54; 32-90). Substantial variations by ethnicity exist for both alcohol-related and liver disease hospitalisations and deaths in Scotland: these exist in subgroups of both White and non-White populations and practical actions are required to ameliorate these differences. © The

2013-10-01

This study aimed to determine the cross-ethnic stability of the predictive relationship of psychopathy for violence. Participants were 424 adult male jail inmates. Psychopathy was assessed using the Psychopathy Checklist-Revised and criminal violence was assessed using a comprehensive database of arrests for violent crimes. Ethnic categories included the groups that make up the vast majority of U.S. inmates: European American (EA, n = 166), African American (AA, n = 174), and Latino American (LA, n = 84). Ethnically aggregated Cox regression survival analyses identified predictive effects for psychopathy. Disaggregated analyses identified ethnic differences: Psychopathy was more strongly predictive of violence among EA (R² = .13, 95% CI [.04, .22], p violence among LA participants (R² = .02, 95% CI [.00, .08], p = .22). Receiver operating characteristic curve analyses yielded an equivalent pattern of results. These findings add to a growing literature suggesting cross-ethnic variability in the predictive power of psychopathy for violence. PsycINFO Database Record (c) 2013 APA, all rights reserved

The relationship between bone marrow adipose tissue and bone mineral density is different between African Americans and Caucasians as well as between men and women. This suggests that the mechanisms that regulate the differentiation and proliferation of bone marrow stromal cells may differ in these populations. It has long been established that there are ethnic and sex differences in bone mineral density (BMD) and fracture risk. Recent studies suggest that bone marrow adipose tissue (BMAT) may play a role in the pathogenesis of osteoporosis. It is unknown whether ethnic and sex differences exist in the relationship between BMAT and BMD. Pelvic BMAT was evaluated in 455 healthy African American and Caucasian men and women (age 18-88 years) using whole-body T1-weighted magnetic resonance imaging. BMD was measured using whole-body dual-energy X-ray absorptiometry. A negative correlation was observed between pelvic BMAT and total body BMD or pelvic BMD (r = -0.533, -0.576, respectively; P BMAT. Menopausal status significantly entered the regression model with total body BMD as the dependent variable. African Americans had higher total body BMD than Caucasians for the same amount of BMAT, and the ethnic difference for pelvic BMD was greater in those participants with a higher BMAT. Men and premenopausal women had higher total body BMD levels than postmenopausal women for the same amount of BMAT. An inverse relationship exists between BMAT and BMD in African American and Caucasian men and women. The observed ethnic and sex differences between BMAT and BMD in the present study suggest the possibility that the mechanisms regulating the differentiation and proliferation of bone marrow stromal cells may differ in these populations.

Racial/ethnic differences in electronic cigarette knowledge, social norms, and risk perceptions among current and former smokers.

Psychosocial factors that may affect electronic cigarette (e-cigarette) initiation or maintenance among racial/ethnic minorities are not well-understood. This study examined racial/ethnic differences in e-cigarette knowledge, risk perceptions, and social norms among current and former smokers. Individuals with a tobacco smoking history and an awareness of e-cigarettes (N=285) were recruited from the community from June to August 2014. Telephone-administered surveys assessed demographics, smoking status, and e-cigarette knowledge, risk perceptions, and normative beliefs. Analyses of covariance and multinomial logistic regression tested associations by race/ethnicity. Controlling for sociodemographics and smoking status, White participants scored significantly higher on e-cigarette knowledge, compared to both Hispanics and African Americans/Blacks. Knowledge was lower among African Americans/Blacks compared to Hispanics. Compared to both Whites and Hispanics, African American/Black participants held lower perceptions regarding e-cigarette health risks and were less likely to view e-cigarettes as addictive. Normative beliefs did not differ by race/ethnicity. In conclusion, e-cigarette knowledge, health risk perceptions, and perceived addictiveness differed by race/ethnicity. The variation in e-cigarette knowledge and beliefs among smokers and former smokers has implications for use, and potentially, dual use. Understanding these relationships in unrepresented populations can inform future research and practice. Copyright © 2017 Elsevier Ltd. All rights reserved.

Previous studies of chronic hepatitis C virus (HCV) treatment have demonstrated variations in response among racial and ethnic groups including poorer efficacy rates among African American and Hispanic patients. The individualized dosing efficacy vs flat dosing to assess optimaL pegylated interferon therapy (IDEAL) trial enrolled 3070 patients from 118 United States centres to compare treatment with peginterferon (PEG-IFN) alfa-2a and ribavirin (RBV) and two doses of PEG-IFN alfa-2b and RBV. This analysis examines treatment response among the major racial and ethnic groups in the trial. Overall, sustained virologic response (SVR) rates were 44% for white, 22% for African American, 38% for Hispanic and 59% for Asian American patients. For patients with undetectable HCV RNA at treatment week 4, the positive predictive value of SVR was 86% for white, 92% for African American, 83% for Hispanic and 89% for Asian American patients. The positive predictive values of SVR in those with undetectable HCV RNA at treatment week 12 ranged from 72% to 81%. Multivariate regression analysis using baseline characteristics demonstrated that treatment regimen was not a predictor of SVR. Despite wide-ranging SVR rates among the different racial and ethnic groups, white and Hispanic patients had similar SVR rates. In all groups, treatment response was largely determined by antiviral activity in the first 12 weeks of treatment. Therefore, decisions regarding HCV treatment should consider the predictive value of the early on-treatment response, not just baseline characteristics, such as race and ethnicity. © 2010 Blackwell Publishing Ltd.

Impact of ethnicity on cardiac adaptation to exercise.

Sheikh, Nabeel; Sharma, Sanjay

2014-04-01

The increasing globalization of sport has resulted in athletes from a wide range of ethnicities emerging onto the world stage. Fuelled by the untimely death of a number of young professional athletes, data generated from the parallel increase in preparticipation cardiovascular evaluation has indicated that ethnicity has a substantial influence on cardiac adaptation to exercise. From this perspective, the group most intensively studied comprises athletes of African or Afro-Caribbean ethnicity (black athletes), an ever-increasing number of whom are competing at the highest levels of sport and who often exhibit profound electrical and structural cardiac changes in response to exercise. Data on other ethnic cohorts are emerging, but remain incomplete. This Review describes our current knowledge on the impact of ethnicity on cardiac adaptation to exercise, starting with white athletes in whom the physiological electrical and structural changes--collectively termed the 'athlete's heart'--were first described. Discussion of the differences in the cardiac changes between ethnicities, with a focus on black athletes, and of the challenges that these variations can produce for the evaluating physician is also provided. The impact of ethnically mediated changes on preparticipation cardiovascular evaluation is highlighted, particularly with respect to false positive results, and potential genetic mechanisms underlying racial differences in cardiac adaptation to exercise are described.

The prevalence and severity of systemic lupus erythematosus (SLE) differs between ethnic groups and geographical regions. Although initially reported as rare, there is growing evidence that SLE is prevalent and runs a severe course in Africa. There is a paucity of prospective studies on African SLE patients. The African Lupus Genetics Network (ALUGEN) is a multicentred framework seeking to prospectively assess outcomes in SLE patients in Africa. Outcomes measured will be death, hospital admission, disease activity flares, and SLE-related damage. We will explore predictors for these outcomes including clinical, serological, socio-demographic, therapeutic and genetic factors. Further, we will investigate comorbidities and health-related quality of life amongst these patients. Data of patients recently (≤ 5 yrs) diagnosed with SLE will be collected at baseline and annual follow-up visits, and captured electronically. The ALUGEN project will facilitate standardized data capture for SLE cases in Africa, allowing participating centres to develop their own SLE registries, and enabling collaboration to enrich our understanding of inter-ethnic and regional variations in disease expression. Comprehensive, high-quality multi-ethnic data on African SLE patients will expand knowledge of the disease and inform clinical practice, in addition to augmenting research capacity and networking links and providing a platform for future biomarker and interventional studies. © The Author(s) 2015.

We have demonstrated considerable variability in the volumes of different glomeruli in given individuals (individual glomerular volume: IGV) in a stereologic study of kidneys at forensic autopsy performed to investigate sudden or unexpected death in people without manifest kidney disease. We review some important associations of IGV by subject characteristics and by ethnic groups. IGVs were measured by the Cavalieri method in 30 glomeruli in each of 111 adult males who belonged to 4 ethnic groups, i.e. US Whites, African-Americans, Africans from Senegal, and Australian Aborigines. Correlations of pooled IGV values with certain subject characteristics were evaluated in the US Whites. Pooled IGV data were compared in subjects across the 4 ethnic groups. In US Whites, mean IGV and its variance were greater with higher age, lower nephron number, lower birth weight, and with gross obesity, hypertension and cardiovascular death. In comparisons by ethnic group, mean IGV and IGV ranges were higher in African-Americans and Australian Aborigines than in US Whites and African Senegalese subjects. We conclude that glomerular enlargement with volume heterogeneity marks more advanced age, relative nephron deficiency, lower birth weight, obesity, hypertension, and advanced cardiovascular disease. The findings in African-Americans and Australian Aborigines suggest that larger IGVs and volume heterogeneity might mark populations with accentuated susceptibility to hypertension and kidney disease, but the data need to be further examined in the context of the determining characteristics defined in the US Whites.

Very little is known about the role of nasal morphology due to ethnic variation on particle deposition pattern in the sinonasal cavity. This preliminary study utilizes computational fluid dynamics (CFD) modeling to investigate sinonasal airway morphology and deposition patterns of intranasal sprayed particles in the nose and sinuses of individuals from four different ethnic groups: African American (Black); Asian; Caucasian; and Latin American. Sixteen subjects (four from each ethnic group) with "normal" sinus protocol computed tomography (CT) were selected for CFD analysis. Three-dimensional reconstruction of each subject's sinonasal cavity was created from their personal CT images. CFD simulations were carried out in ANSYS Fluent(™) in two phases: airflow phase was done by numerically solving the Navier-Stokes equations for steady state laminar inhalation; and particle dispersed phase was solved by tracking injected (sprayed) particles through the calculated airflow field. A total of 10,000 particle streams were released from each nostril, 1000 particles per diameter ranging from 5 μm to 50 μm, with size increments of 5 μm. As reported in the literature, Caucasians (5.31 ± 0.42 cm(-1)) and Latin Americans (5.16 ± 0.40cm(-1)) had the highest surface area to volume ratio, while African Americans had highest nasal index (95.91 ± 2.22). Nasal resistance (NR) was highest among Caucasians (0.046 ± 0.008 Pa.s/mL) and Asians (0.042 ± 0.016Pa.s/mL). Asians and African Americans had the most regions with particle deposition for small (5 μm-15 μm) and large (20 μm-50 μm) particle sizes, respectively. Asians and Latin Americans individuals had the most consistent regional particle deposition pattern in the main nasal cavities within their respective ethnic groups. Preliminary results from these ethnic groups investigated showed that Caucasians and Latin Americans had the least patent nasal cavity. Furthermore, Caucasians

The authors examined the hypothesized influence of maternal and paternal hostility on youth delinquency over time. The investigation addressed significant gaps in earlier research on parental hostility, including the neglect of father effects, especially in African American families. Using prospective, longitudinal data from community samples of European American (n = 422) and African American (n = 272) 2-parent families, the authors examined the independent effects of paternal and maternal hostility on youth delinquency. The results indicated that paternal hostility significantly predicted relative increases in youth delinquent behaviors above and beyond the effects of maternal hostility; conversely, maternal hostility did not predict youth delinquency after controlling for paternal hostility. Multiple-group analyses yielded similar results for both ethnic groups and for boys and girls. These results underscore the importance of including both parents in research on diverse families. Neglecting fathers provides an incomplete account of parenting in relation to youth development.

Two-part latent growth models examined associations between two forms of peer status (popularity, likability) and adolescents' alcohol use trajectories throughout high school; ethnicity was examined as a moderator. Ninth-grade low-income adolescents (N = 364; Mage = 15.08; 52.5% Caucasian; 25.8% African American; 21.7% Latino) completed sociometric nominations of peer status and aggression at baseline, and reported their alcohol use every 6 months. After controlling for gender, aggression, ethnicity, and socioeconomic status, popularity-but not likability-prospectively predicted alcohol use trajectories. However, these effects were moderated by ethnicity, suggesting popularity as a risk factor for alcohol use probability and frequency among Caucasian and Latino, but not African American adolescents. Results suggest that developmental correlates of peer status should be considered within cultural context. © 2015 The Authors.

Intraocular pressure (IOP) is a major risk factor, as well as the only modifiable risk factor, for glaucoma. Racial differences have been observed in IOP measurements with individuals of African descent experiencing the highest IOP when compared with other ethnic groups. The purpose of this study was to examine the relationship between genetic ancestry and IOP in Latinos. Population-based genetic association study. A total of 3541 participants recruited from the Los Angeles Latino Eye Study. Study participants were genotyped using the Illumina OmniExpress BeadChip (∼730K markers). We used STRUCTURE to estimate individual genetic ancestry. Simple and multiple linear regression, as well as quantile regression, analyses were performed to investigate the relationship between genetic ancestry and IOP. The relationship between genetic ancestry and IOP in Latinos. African ancestry was significantly associated with higher IOP in Latinos in our simple linear regression analysis (P = 0.002). After adjusting for age, gender, body mass index, systolic blood pressure, central corneal thickness, and type 2 diabetes, this association remained significant (P = 0.0005). The main association was modified by a significant interaction between African ancestry and hypertension (P = 0.037), with hypertensive individuals experiencing a greater increase in IOP with increasing African ancestry. To our knowledge, we demonstrate for the first time that African ancestry and its interaction with hypertension are associated with higher IOP in Latinos.

Cancer Genomics: Diversity and Disparity Across Ethnicity and Geography.

Ethnic and geographic differences in cancer incidence, prognosis, and treatment outcomes can be attributed to diversity in the inherited (germline) and somatic genome. Although international large-scale sequencing efforts are beginning to unravel the genomic underpinnings of cancer traits, much remains to be known about the underlying mechanisms and determinants of genomic diversity. Carcinogenesis is a dynamic, complex phenomenon representing the interplay between genetic and environmental factors that results in divergent phenotypes across ethnicities and geography. For example, compared with whites, there is a higher incidence of prostate cancer among Africans and African Americans, and the disease is generally more aggressive and fatal. Genome-wide association studies have identified germline susceptibility loci that may account for differences between the African and non-African patients, but the lack of availability of appropriate cohorts for replication studies and the incomplete understanding of genomic architecture across populations pose major limitations. We further discuss the transformative potential of routine diagnostic evaluation for actionable somatic alterations, using lung cancer as an example, highlighting implications of population disparities, current hurdles in implementation, and the far-reaching potential of clinical genomics in enhancing cancer prevention, diagnosis, and treatment. As we enter the era of precision cancer medicine, a concerted multinational effort is key to addressing population and genomic diversity as well as overcoming barriers and geographical disparities in research and health care delivery. © 2015 by American Society of Clinical Oncology.

As the office-awake blood pressure (BP) difference (white-coat effect) in African-Americans has not been evaluated, we studied the ethnicity, professional status (nurse versus doctor) and sex of the observer on the white-coat effect in African-American patients with hypertension. Seated clinical BP measurements were obtained in random order by an African-American male research physician, a Caucasian male research physician, and a Caucasian female nurse who is of similar age and clinical experience. Within 1 week, ambulatory BP recordings were performed. A total of 65 African-American patients [54+/-13 years, 55% women, body mass index (BMI) 31+/-6 kg/m, 62% on drug therapy, 28% current smokers] participated in the study. Twenty-two percent had a systolic white-coat effect >20 mmHg and 49% had a diastolic white-coat effect >10 mmHg (average of all observers). Although there were no differences in the magnitude of the white-coat effect among the three study observers, the primary physician's diastolic white-coat effect was significantly greater than that of the African-American physician (14+/-12 vs. 9+/-12, P=0.05), but not the systolic white-coat effect (16+/-16 vs. 10+/-16 mmHg, P=0.09). BMI positively correlated with the systolic and diastolic white-coat effect (r=0.30, P=0.02 and r=0.41, P=0.0001), but this correlation was true only for female patients in multiple regression analyses. BMI significantly predicted the systolic (P=0.043) and diastolic (P=0.004) white-coat effects. A white-coat effect is relatively common in African-American patients with hypertension and is the largest when the observer is their usual doctor. The clinical observer's ethnicity or sex does not play an important role in generating a white-coat effect in African-American patients with hypertension.

We examine access to and type of social support after initial receipt of an abnormal mammogram across non-Latina White (NLW), African American, and Latina women. This cross-sectional study used a mixed method design, with quantitative and qualitative measures. Women were recruited through 2 community advocates and 3 breast-health-related care organizations. With regard to access, African American women were less likely to access social support relative to NLW counterparts. Similar nonsignificant differences were found for Latinas. Women did not discuss results with family and friends to avoid burdening social networks and negative reactions. Networks' geographic constraints and medical mistrust influenced Latina and African American women's decisions to discuss results. With regard to type of social support, women reported emotional support across ethnicity. Latina and African American women reported more instrumental support, whereas NLW women reported more informational support in the context of their well-being. There are shared and culturally unique aspects of women's experiences with social support after initially receiving an abnormal mammogram. Latina and African American women may particularly benefit from informational support from health care professionals. Communitywide efforts to mitigate mistrust and encourage active communication about cancer may improve ethnic disparities in emotional well-being and diagnostic resolution during initial receipt of an abnormal mammogram.

Large genome-wide association (GWA) studies of European ancestry individuals have identified multiple genetic variants influencing iron status. Studies on the generalizability of these associations to African ancestry populations have been limited. These studies are important given interethnic differences in iron status and the disproportionate burden of iron deficiency among African ancestry populations. We tested the associations of 20 previously identified iron status-associated single nucleotide polymorphisms (SNPs) in 628 Kenyans, 609 Tanzanians, 608 South Africans and 228 African Americans. In each study, we examined the associations present between 20 SNPs with ferritin and haemoglobin, adjusting for age, sex and CRP levels. In the meta analysis including all 4 African ancestry cohorts, we replicated previously reported associations with lowered haemoglobin concentrations for rs2413450 (β = -0.19, P = 0.02) and rs4820268 (β = -0.16, P = 0.04) in TMPRSS6. An association with increased ferritin concentrations was also confirmed for rs1867504 in TF (β = 1.04, P = ancestry individuals. While there is now evidence for the associations of a number of genetic variants with iron status in both European and African ancestry populations, the considerable lack of concordance highlights the importance of continued ancestry-specific studies to elucidate the genetic underpinnings of iron status in ethnically diverse populations.

Mothers of young adults with intellectual disability: multiple roles, ethnicity and well-being.

Two opposing perspectives--role strain and role enhancement--were considered as predictive of women's psychological and physical health. The authors examined the relation between multiple role occupancy (parenting, employment, marriage) and well-being (depression and health) among mothers of young adults with intellectual disability (ID). Participants were 226 mothers aged 35-70 years old caring for a young adult aged 16-26 years old with moderate to severe/profound ID. Mothers were of either Latino ethnicity (n=117) or Anglo (n=109). Mothers' ethnicity and degree of acculturation and young adults' adaptive behaviour and behaviour problems were examined as potential moderators. Mothers who were employed, married, or both reported better well-being than mothers who were both unemployed and unmarried, especially when their offspring had relatively higher adaptive functioning. This relationship between role occupancy and well-being was fully mediated by socio-economic status (SES) factors. Results did not suggest a role enhancement effect, but instead indicated a role shortage effect; unemployed, unmarried mothers experienced markedly poor well-being, while all other mothers experienced comparable well-being. Well-being scores were higher for Anglo than for Latino mothers; this relationship was entirely accounted for by SES. In Latina mothers, the relation between role occupancy and well-being was moderated by degree of acculturation. Findings suggest that multiple roles benefit mothers of young adults with ID primarily through their impact on socio-economic resources. For more acculturated Latina mothers, occupying more roles predicted better well-being even after controlling for SES. Latina mothers who were unemployed and unmarried had lower SES, and this group emerged as at particular risk. The latter group may benefit most from respite assistance and other interventions aimed at addressing their physical and mental health.

Full Text Available Leukocyte telomere length(LTL has been associated with age, self-reported race/ethnicity, gender, education, and psychosocial factors, including perceived stress, and depression. However, inconsistencies in associations of LTL with disease and other phenotypes exist across studies. Population characteristics, including race/ethnicity, laboratory methods, and statistical approaches in LTL have not been comprehensively studied and could explain inconsistent LTL associations.LTL was measured using Southern Blot in 1510 participants from a multi-ethnic, multi-center study combining data from 3 centers with different population characteristics and laboratory processing methods. Main associations between LTL and psychosocial factors and LTL and race/ethnicity were evaluated and then compared across generalized estimating equations(GEE and linear regression models. Statistical models were adjusted for factors typically associated with LTL(age, gender, cancer status and also accounted for factors related to center differences, including laboratory methods(i.e., DNA extraction. Associations between LTL and psychosocial factors were also evaluated within race/ethnicity subgroups (Non-hispanic Whites, African Americans, and Hispanics.Beyond adjustment for age, gender, and cancer status, additional adjustments for DNA extraction and clustering by center were needed given their effects on LTL measurements.

Breast cancer is the second leading cause of cancer related deaths among women aged 40-55 in the United States and currently affects more than one in ten women worldwide. It is also one of the most diagnosed cancers in women both in wealthy and poor countries. Fortunately, the mortality rate from breast cancer has decreased in recent years due to increased emphasis on early detection and more effective treatments in White population. Although the mortality rates have declined in some ethnic populations, the overall cancer incidence among African American and Hispanic populations has continued to grow. The goal of the present review article was to highlight similarities and differences in breast cancer morbidity and mortality rates primarily among African American women compared to White women in the United States. To reach our goal, we conducted a search of articles in journals with a primary focus on minority health, and authors who had published articles on racial/ethnic disparity related to breast cancer patients. A systematic search of original research was conducted using MEDLINE, PUBMED and Google Scholar databases. We found that racial/ethnic disparities in breast cancer may be attributed to a large number of clinical and non-clinical risk factors including lack of medical coverage, barriers to early detection and screening, more advanced stage of disease at diagnosis among minorities, and unequal access to improvements in cancer treatment. Many African American women have frequent unknown or unstaged breast cancers than White women. These risk factors may explain the differences in breast cancer treatment and survival rate between African American women and White women. New strategies and approaches are needed to promote breast cancer prevention, improve survival rate, reduce breast cancer mortality, and ultimately improve the health outcomes of racial/ethnic minorities.

This study investigated the academic interests and goals of 223 African American, Latino/a, Southeast Asian, and Native American undergraduate students in two groups: biological science and engineering (S/E) majors. Using social cognitive career theory (Lent, Brown, & Hackett, 1994), we examined the relationships of social cognitive variables (math/science academic self-efficacy, math/science outcome expectations), along with the influence of ethnic variables (ethnic identity, other-group orientation) and perceptions of campus climate to their math/science interests and goal commitment to earn an S/E degree. Path analysis revealed that the hypothesized model provided good overall fit to the data, revealing significant relationships from outcome expectations to interests and to goals. Paths from academic self-efficacy to S/E goals and from interests to S/E goals varied for students in engineering and biological science. For both groups, other-group orientation was positively related to self-efficacy and support was found for an efficacy-mediated relationship between perceived campus climate and goals. Theoretical and practical implications of the study's findings are considered as well as future research directions.

To investigate the role of body composition (body weight, fat distribution and weight change over time) in ethnic differences in the incidence of hypertension in an ethnic Dutch, South Asian Surinamese and African Surinamese background population living in the Netherlands. We included 361 participants without hypertension at baseline (147 ethnic Dutch, 82 South Asian Surinamese, 132 African Surinamese), aged 35-60 years, in whom anthropometric measurements and blood pressures were measured at baseline and after mean 9 years of follow-up. Data were analysed using logistic regression analyses, with hypertension at follow up as a dependent variable. Body weight, fat distribution and weight gain were positively associated with the risk of developing hypertension; these associations did not statistically significantly differ between ethnic groups [odds ratios (ORs), 95% confidence interval (95% CI) per SD: BMI 1.5 (1.2-2.0); waist circumference 1.5 (1.2-1.9); waist to hip ratio (WHR) 1.4 (1.1-1.9), weight gain of 1-2.9 kg/m 1.8 (0.9-3.8)]. As compared with Dutch, a higher incidence of hypertension was found among South Asian Surinamese [OR 2.6 (1.4-4.8)] and in particular among African Surinamese [OR 3.1 (1.76-5.30)]. Among South Asian Surinamese, adjustment for WHR attenuated the OR the most [OR 1.9 (1.0-3.7)]; among African Surinamese, the strongest effect was observed for adjustment by BMI and WHR simultaneously [OR 2.5 (1.4-4.4)]. The ethnic differences in the incidence of hypertension among a middle-aged group with a Dutch, South Asian Surinamese and African Surinamese background were partly explained by body composition. This suggests that other factors may be involved, including genetic factors or unidentified other determinants.

Recruiting and engaging African-American men in health research.

Improving the health of black and minority ethnic (BME) men in the US continues to be a public health priority. Compared with men of other races and ethnicities, African-American men have higher rates of mortality and morbidity from chronic illness and diseases including cancer, heart disease, prostate cancer, diabetes and HIV/AIDS. One way to address these disparities is to include African-American men in health research, to elicit their perspectives on health risks and protective factors. These can then inform interventions aimed at reducing health disparities. However, challenges remain in recruiting and engaging African-American men in health research. To provide strategies for recruiting African-American men in health research, using as an exemplar a qualitative study of fathers' perspectives of sexual health promotion with young African-American males. Efforts are needed to increase the representation of African-American men in health research. Ensuring that researchers are aware of the cultural, social and environmental factors related to decisions to participate in research can lead to effective methods to recruit and engage them. There are several essential strategies for increasing African-American men's participation in health research: ensuring the research team is culturally and gender-sensitive; recruiting in trusted environments; using respected gatekeepers; developing trust with participants; and being transparent. Implementing strategies to include African-American men in health research has the potential to improve health disparities in the US. ©2018 RCN Publishing Company Ltd. All rights reserved.

To examine the association between obesity and depressed mood in a large multi-ethnic population and check for consistency in this association across six ethnic groups. Data of 21,030 persons (18-70 years) were sourced from the HELIUS study. Cross-sectional relationships between obesity measures [body mass index (kg/m 2 ) and waist circumference (cm)] and depressed mood (PHQ-9 score ≥ 10) were analysed. Consistency of associations was investigated across ethnic groups by interaction terms (ethnicity*obesity measures) in basic (age, sex, education) and fully (health behaviours and somatic health) adjusted models. Obesity was prevalent in all ethnic groups, but varied substantially. After sociodemographic adjustment, obesity measures were associated with increased odds of depressed mood but this was inconsistent across ethnic groups. Obesity (BMI ≥ 30 or highest waist circumference quartile) was strongly and significantly associated with depressed mood in the Dutch [Odds Ratio (OR) = 1.72; 95% Confidence intervals (CI) 1.24-2.40, and OR = 1.86; 95% CI 1.38-2.50], respectively, and African Surinamese (OR = 1.60; 95% CI 1.29-1.98 and OR = 1.59; 95% CI 1.27-2.00, respectively) but had a weaker, non-significant association in other ethnic groups (South-Asian Surinamese, Ghanaian, Moroccan, Turkish groups). Adjustment for health behaviours and somatic health had limited effect on this pattern. Obesity was associated with a higher risk of depressed mood. However, ethnic differences were found: the obesity-depressed mood association was strong in the Dutch and African Surinamese populations, but not in other ethnic groups. Future studies should explore whether differential normative values or pathophysiology across ethnic groups explain why the obesity-depression association is inconsistent across ethnic groups.

Full Text Available Abstract Background Asthma and allergy represent complex phenotypes, which disproportionately burden ethnic minorities in the United States. Strong evidence for genomic factors predisposing subjects to asthma/allergy is available. However, methods to utilize this information to identify high risk groups are variable and replication of genetic associations in African Americans is warranted. Methods We evaluated 41 single nucleotide polymorphisms (SNP and a deletion corresponding to 11 genes demonstrating association with asthma in the literature, for association with asthma, atopy, testing positive for food allergens, eosinophilia, and total serum IgE among 141 African American children living in Detroit, Michigan. Independent SNP and haplotype associations were investigated for association with each trait, and subsequently assessed in concert using a genetic risk score (GRS. Results Statistically significant associations with asthma were observed for SNPs in GSTM1, MS4A2, and GSTP1 genes, after correction for multiple testing. Chromosome 11 haplotype CTACGAGGCC (corresponding to MS4A2 rs574700, rs1441586, rs556917, rs502581, rs502419 and GSTP1 rs6591256, rs17593068, rs1695, rs1871042, rs947895 was associated with a nearly five-fold increase in the odds of asthma (Odds Ratio (OR = 4.8, p = 0.007. The GRS was significantly associated with a higher odds of asthma (OR = 1.61, 95% Confidence Interval = 1.21, 2.13; p = 0.001. Conclusions Variation in genes associated with asthma in predominantly non-African ethnic groups contributed to increased odds of asthma in this African American study population. Evaluating all significant variants in concert helped to identify the highest risk subset of this group.

Medication outcome literature in schizophrenia across racial-ethnic groups is sparse, with inconsistent findings. The Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study provided an opportunity for exploratory analyses of racial-ethnic outcomes. The study objective was to examine race-ethnicity outcomes for CATIE's main outcome (study discontinuation) and secondary outcomes. CATIE participants included whites (non-Hispanic) (N=722), African Americans (N=506), and Hispanics (N=170). Survival analyses and mixed-effects regression modeling were conducted, with adjustment for baseline sociodemographic differences and baseline scores of the secondary outcomes. Racial-ethnic groups had unique patterns of outcomes. Hispanics were much more likely to discontinue for lack of efficacy from perphenazine (64% versus 42% non-Hispanic whites and 24% African Americans) and ziprasidone (71% versus 40% non-Hispanic whites and 24% African Americans); Hispanics' quality of life also declined on these medications. Non-Hispanic whites were more likely to discontinue for lack of efficacy in general (averaging olanzapine, quetiapine, and risperidone discontinuation rates). African Americans were less likely to continue after the first phase (32% continuing versus 40% for non-Hispanic whites and 41% Hispanics). Discontinuations were driven by research burden, personal issues, and unspecified loss to follow-up. Non-Hispanic whites had higher depression scores during the follow-up period. African Americans had fewer side effects. CATIE results did not show disparities favoring non-Hispanic whites. CATIE may have provided state-of-the-art treatment and thus reduced disparate treatments observed in community clinics. African Americans discontinued even after consideration of socioeconomic differences. Why perphenazine and ziprasidone may be less effective with Hispanics should be explored.

2015-11-01

A large electronic database of histopathology reports was used to study the ethnic distribution of microscopic colitis in the United States. Miraca Life Sciences is a nation-wide pathology laboratory that receives biopsy specimens submitted by 1500 gastroenterologists distributed throughout the United States. In a case-control study, the prevalence of microscopic colitis in 4 ethnic groups (East Asians, Indians, Hispanics, and Jews) was compared with that of all other ethnic groups (composed of American Caucasians and African Americans), serving as reference group. A total of 11,706 patients with microscopic colitis were included in the analysis. In all ethnic groups alike, microscopic colitis was more common in women than men (78% versus 22%, odds ratio = 3.40, 95% confidence interval = 3.26-3.55). In all ethnic groups, the prevalence of microscopic colitis showed a continuous age-dependent rise. Hispanic patients with microscopic colitis were on average younger than the reference group (59.4 ± 16.2 years versus 64.2 ± 13.8 years, P variations of its occurrence among different ethnic groups. Such variations could point at differences in the exposure to environmental risk factors.

To explore ethnic inequalities in periodontal disease among British adults, and the role of socioeconomic position (SEP) in those inequalities. We analysed data on 1925 adults aged 16-65 years, from the East London Oral Health Inequality (ELOHI) Study, which included a random sample of adults living in an ethnically diverse and socially deprived area. Participants completed a questionnaire and were clinically examined for the number of teeth with periodontal pocket depth (PPD)≥4 mm and loss of attachment (LOA)≥4 mm. Ethnic inequalities in periodontal measures were assessed in negative binomial regression models before and after adjustment for demographic (gender and age groups) and SEP indicators (education and socioeconomic classification). Compared to White British, Pakistani, Indian, Bangladeshi and Asian Others had more teeth with PPD≥4 mm whereas White East European, Black African and Bangladeshi had more teeth with LOA≥4 mm, after adjustments for demographic and SEP measures. The association of ethnicity with periodontal disease was moderated by education, but not by socioeconomic classification. Stratified analysis showed that ethnic disparities in the two periodontal measures were limited to more educated groups. This study showed considerable ethnic disparities in periodontal disease between and within the major ethnic categories. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Neighborhood characteristics have been associated with obesity, but less is known whether relationships vary by race/ethnicity. This study examined the relationship between soda consumption - a behavior strongly associated with obesity - and weight status with neighborhood sociodemographic, social, and built environments by race/ethnicity. We merged data on adults from the 2011-2013 California Health Interview Survey, U.S. Census data, and InfoUSA (n=62,396). Dependent variables were soda consumption and weight status outcomes (body mass index and obesity status). Main independent variables were measures of three neighborhood environments: social (social cohesion and safety), sociodemographic (neighborhood socioeconomic status, educational attainment, percent Asian, percent Hispanic, and percent black), and built environments (number of grocery stores, convenience stores, fast food restaurants, and gyms in neighborhood). We fit multi-level linear and logistic regression models, stratified by individual race/ethnicity (NH (non-Hispanic) Whites, NH African Americans, Hispanics, and NH Asians) controlling for individual-level characteristics, to estimate neighborhood contextual effects on study outcomes. Lower neighborhood educational attainment was associated with higher odds of obesity and soda consumption in all racial/ethnic groups. We found fewer associations between study outcomes and the neighborhood, especially the built environment, among NH African Americans and NH Asians. While improvements to neighborhood environment may be promising to reduce obesity, null associations among minority subgroups suggest that changes, particularly to the built environment, may alone be insufficient to address obesity in these groups.

Conspicuous facial pores are one type of serious aesthetic defects for many women. However, the mechanism(s) that underlie the conspicuousness of facial pores remains unclear. We previously characterized the epidermal architecture around facial pores that correlated with the appearance of those pores. A survey was carried out to elucidate ethnic-dependent differences in facial pore size and in epidermal architecture. The subjects included 80 healthy women (aged 30-39: Caucasians, Asians, Hispanics and African Americans) living in Dallas in the USA. First, surface replicas were collected to compare pore sizes of cheek skin. Second, horizontal cross-sectioned images from cheek skin were obtained non-invasively from the same subjects using in vivo confocal laser scanning microscopy (CLSM) and the severity of impairment of epidermal architecture around facial pores was determined. Finally, to compare racial differences in the architecture of the interfollicular epidermis of facial cheek skin, horizontal cross-sectioned images were obtained and the numbers of dermal papillae were counted. Asians had the smallest pore areas compared with other racial groups. Regarding the epidermal architecture around facial pores, all ethnic groups observed in this study had similar morphological features and African Americans showed substantially more severe impairment of architecture around facial pores than any other racial group. In addition, significant differences were observed in the architecture of the interfollicular epidermis between ethnic groups. These results suggest that facial pore size, the epidermal architecture around facial pores and the architecture of the interfollicular epidermis differ between ethnic groups. This might affect the appearance of facial pores.

The prevalence of food allergy is rising among US children. Little is known about racial/ethnic disparities in food allergy. We performed a systematic literature review to understand racial/ethnic disparities in food allergy in the United States. We searched PubMed/MEDLINE, Embase, and Scopus for original data about racial/ethnic disparities in the diagnosis, prevalence, treatment, or clinical course of food allergy or sensitization, with a particular focus on black (African American) race. Articles were analyzed by study methodology, racial/ethnic composition, food allergy definition, outcomes, summary statistic used, and covariate adjustment. Twenty of 645 identified articles met inclusion criteria. The studies used multiple differing criteria to define food allergy, including self-report, sensitization assessed by serum food-specific IgE to selected foods without corroborating history, discharge codes, clinic chart review, and event-reporting databases. None used oral food challenge. In 12 studies, black persons (primarily children) had significantly increased adjusted odds of food sensitization or significantly higher proportion or odds of food allergy by self-report, discharge codes, or clinic-based chart review than white children. Major differences in study methodology and reporting precluded calculation of a pooled estimate of effect. Sparse and methodologically limited data exist about racial/ethnic disparity in food allergy in the United States. Available data lack a common definition for food allergy and use indirect measures of allergy, not food challenge. Although data suggest an increased risk of food sensitization, self-reported allergy, or clinic-based diagnosis of food allergy among black children, no definitive racial/ethnic disparity could be found among currently available studies.

Bornman, E

1999-08-01

This study examined the relationship between self-image and ethnic identification among 3 South African groups. Participants included random samples of 347 Afrikaans-speaking Whites, 113 English-speaking Whites, and 466 Blacks in urban Gauteng. Positive and negative self-image were extracted using the Rosenberg Self-Esteem Scale (M. Rosenberg, 1965). Afrikaans-speaking Whites had the most positive self-image and Blacks the most negative self-image. A positive self-image was correlated with stronger ethnic identification among Afrikaans-speaking Whites. The opposite was true for Blacks. This relationship was insignificant among English-speaking Whites. Ambivalence toward ingroup identity was persistently correlated with self-image for all groups.

The factor structure and potential uniform differential item functioning (DIF) among gender and three racial/ethnic groups of adolescents (African American, Latino, White) were evaluated for attention deficit/hyperactivity disorder (ADHD), conduct disorder (CD), and oppositional defiant disorder (ODD) symptom scores of the DISC Predictive Scales (DPS; Leung et al., 2005; Lucas et al., 2001). Primary caregivers reported on DSM-IV ADHD, CD, and ODD symptoms for a probability sample of 4,491 children from three geographical regions who took part in the Healthy Passages study (mean age = 12.60 years, SD = 0.66). Confirmatory factor analysis indicated that the expected 3-factor structure was tenable for the data. Multiple indicators multiple causes (MIMIC) modeling revealed uniform DIF for three ADHD and 9 ODD item scores, but not for any of the CD item scores. Uniform DIF was observed predominantly as a function of child race/ethnicity, but minimally as a function of child gender. On the positive side, uniform DIF had little impact on latent mean differences of ADHD, CD, and ODD symptomatology among gender and racial/ethnic groups. Implications of the findings for researchers and practitioners are discussed. (c) 2015 APA, all rights reserved).

Full Text Available African Americans are disproportionately affected by type 2 diabetes (T2DM yet few studies have examined T2DM using genome-wide association approaches in this ethnicity. The aim of this study was to identify genes associated with T2DM in the African American population. We performed a Genome Wide Association Study (GWAS using the Affymetrix 6.0 array in 965 African-American cases with T2DM and end-stage renal disease (T2DM-ESRD and 1029 population-based controls. The most significant SNPs (n = 550 independent loci were genotyped in a replication cohort and 122 SNPs (n = 98 independent loci were further tested through genotyping three additional validation cohorts followed by meta-analysis in all five cohorts totaling 3,132 cases and 3,317 controls. Twelve SNPs had evidence of association in the GWAS (P<0.0071, were directionally consistent in the Replication cohort and were associated with T2DM in subjects without nephropathy (P<0.05. Meta-analysis in all cases and controls revealed a single SNP reaching genome-wide significance (P<2.5×10(-8. SNP rs7560163 (P = 7.0×10(-9, OR (95% CI = 0.75 (0.67-0.84 is located intergenically between RND3 and RBM43. Four additional loci (rs7542900, rs4659485, rs2722769 and rs7107217 were associated with T2DM (P<0.05 and reached more nominal levels of significance (P<2.5×10(-5 in the overall analysis and may represent novel loci that contribute to T2DM. We have identified novel T2DM-susceptibility variants in the African-American population. Notably, T2DM risk was associated with the major allele and implies an interesting genetic architecture in this population. These results suggest that multiple loci underlie T2DM susceptibility in the African-American population and that these loci are distinct from those identified in other ethnic populations.

2015-07-01

Although the prevalence of mental illness is similar across ethnic groups, a large disparity exists in the utilization of services. Mental health attributions, causal beliefs regarding the etiology of mental illness, may contribute to this disparity. To understand mental health attributions across diverse ethnic backgrounds, we conducted focus groups with African American (n = 8; 24 %), Asian American (n = 6; 18 %), Latino/Hispanic (n = 9; 26 %), and White (n = 11; 32 %) participants. We solicited attributions about 19 mental health disorders, each representing major sub-categories of the DSM-IV. Using a grounded theory approach, participant responses were categorized into 12 themes: Biological, Normalization, Personal Characteristic, Personal Choice, Just World, Spiritual, Family, Social Other, Environment, Trauma, Stress, and Diagnosis. Results indicate that ethnic minorities are more likely than Whites to mention spirituality and normalization causes. Understanding ethnic minority mental health attributions is critical to promote treatment-seeking behaviors and inform culturally responsive community-based mental health services.

Ischemic heart disease (IHD) rates are lower in UK black Africans and black Caribbeans and higher in South Asians when compared with white Europeans. Ethnic differences in lipid concentrations may play a part in these differences. The objective was to investigate blood lipid and dietary patterns in UK children from different ethnic groups. This was a cross-sectional study in 2026 UK children (including 285 black Africans, 188 black Caribbeans, 534 South Asians, and 512 white Europeans) attending primary schools in London, Birmingham, and Leicester. We measured fasting blood lipid concentrations and collected 24-h dietary recalls. In comparison with white Europeans, black African children had lower total cholesterol (-0.14 mmol/L; 95% CI: -0.25, -0.04 mmol/L), LDL-cholesterol (-0.10 mmol/L; 95% CI: -0.20, -0.01 mmol/L), and triglyceride concentrations (proportional difference: -0.11 mmol/L; 95% CI: -0.16, -0.06 mmol/L); HDL-cholesterol concentrations were similar. Lower saturated fat intakes (-1.4%; 95% CI: -1.9%, -0.9%) explained the differences between total and LDL cholesterol. Black Caribbean children had total, LDL-cholesterol, HDL-cholesterol, and triglyceride concentrations similar to those for white Europeans, with slightly lower saturated fat intakes. South Asian children had total and LDL-cholesterol concentrations similar to those for white Europeans, lower HDL-cholesterol concentrations (-0.7 mmol/L; 95% CI: -0.11, -0.03 mmol/L), and elevated triglyceride concentrations (proportional difference: 0.14 mmol/L; 95% CI: 0.09, 0.20 mmol/L); higher polyunsaturated and monounsaturated fat intakes did not explain these lipid differences. Only black African children had a blood lipid profile and associated dietary pattern likely to protect against future IHD. The loss of historically lower LDL-cholesterol concentrations among UK black Caribbeans and South Asians may have important adverse consequences for future IHD risk in these groups.

Leukocyte telomere length(LTL) has been associated with age, self-reported race/ethnicity, gender, education, and psychosocial factors, including perceived stress, and depression. However, inconsistencies in associations of LTL with disease and other phenotypes exist across studies. Population characteristics, including race/ethnicity, laboratory methods, and statistical approaches in LTL have not been comprehensively studied and could explain inconsistent LTL associations. LTL was measured using Southern Blot in 1510 participants from a multi-ethnic, multi-center study combining data from 3 centers with different population characteristics and laboratory processing methods. Main associations between LTL and psychosocial factors and LTL and race/ethnicity were evaluated and then compared across generalized estimating equations(GEE) and linear regression models. Statistical models were adjusted for factors typically associated with LTL(age, gender, cancer status) and also accounted for factors related to center differences, including laboratory methods(i.e., DNA extraction). Associations between LTL and psychosocial factors were also evaluated within race/ethnicity subgroups (Non-hispanic Whites, African Americans, and Hispanics). Beyond adjustment for age, gender, and cancer status, additional adjustments for DNA extraction and clustering by center were needed given their effects on LTL measurements. In adjusted GEE models, longer LTL was associated with African American race (Beta(β)(standard error(SE)) = 0.09(0.04), p-value = 0.04) and Hispanic ethnicity (β(SE) = 0.06(0.01), p-value = 0.02) compared to Non-Hispanic Whites. Longer LTL was also associated with less than a high school education compared to having greater than a high school education (β(SE) = 0.06(0.02), p-value = 0.04). LTL was inversely related to perceived stress (β(SE) = -0.02(0.003), pethnic circumstances and could impact future health disparity studies.

Lack of awareness of HIV status is associated with an increased likelihood of HIV transmission. We surveyed 633 men who have sex with men (MSM) from diverse ethnic groups recruited from a variety of community venues in a U.S. Midwestern city with rising HIV infection rates. Our first aim was to describe patterns of sexual risk, annual HIV testing frequency, and venues where information about HIV and HIV testing could be disseminated to inner-city MSM. Our second aim was to identify preferred sources to receive information about HIV testing and determine whether these preferences differed by ethnic background. Results indicated that despite similar proportions of high-sexual risk behaviors, compared with African American and Latino MSM, smaller proportions of non-Hispanic White MSM had received an HIV test in the last 12 months. Despite ethnic differences in health care access, a physician's office was the most common HIV testing site. Overall, a majority conveyed a preference to see advertisements in mainstream media outlets. However, when preferences were stratified by ethnicity, African American MSM were the least likely to prefer receiving information from mainstream media and conveyed a stronger preference to receive information from authority figures than non-Hispanic White and Hispanic MSM.

Crossing Boundaries: Nativity, Ethnicity, and Mate Selection

The influx of immigrants has increased diversity among ethnic minorities and indicates that they may take multiple integration paths in American society. Previous research on ethnic integration often focuses on panethnic differences and few have explored ethnic diversity within a racial or panethnic context. Using 2000 U.S. census data for Puerto Rican, Mexican, Chinese, and Filipino origin individuals, we examine differences in marriage and cohabitation with whites, with other minorities, within a panethnic group, and within an ethnic group by nativity status. Ethnic endogamy is strong and, to a less extent, so is panethnic endogamy. Yet, marital or cohabiting unions with whites remain an important path of integration but differ significantly by ethnicity, nativity, age at arrival, and educational attainment. Meanwhile, ethnic differences in marriage and cohabitation with other racial or ethnic minorities are strong. Our analysis supports that unions with whites remain a major path of integration, but other paths of integration also become viable options for all ethnic groups. PMID:22350840

Single-trait and multi-trait genome-wide association analyses identify novel loci for blood pressure in African-ancestry populations.

Full Text Available Hypertension is a leading cause of global disease, mortality, and disability. While individuals of African descent suffer a disproportionate burden of hypertension and its complications, they have been underrepresented in genetic studies. To identify novel susceptibility loci for blood pressure and hypertension in people of African ancestry, we performed both single and multiple-trait genome-wide association analyses. We analyzed 21 genome-wide association studies comprised of 31,968 individuals of African ancestry, and validated our results with additional 54,395 individuals from multi-ethnic studies. These analyses identified nine loci with eleven independent variants which reached genome-wide significance (P < 1.25×10-8 for either systolic and diastolic blood pressure, hypertension, or for combined traits. Single-trait analyses identified two loci (TARID/TCF21 and LLPH/TMBIM4 and multiple-trait analyses identified one novel locus (FRMD3 for blood pressure. At these three loci, as well as at GRP20/CDH17, associated variants had alleles common only in African-ancestry populations. Functional annotation showed enrichment for genes expressed in immune and kidney cells, as well as in heart and vascular cells/tissues. Experiments driven by these findings and using angiotensin-II induced hypertension in mice showed altered kidney mRNA expression of six genes, suggesting their potential role in hypertension. Our study provides new evidence for genes related to hypertension susceptibility, and the need to study African-ancestry populations in order to identify biologic factors contributing to hypertension.

Sexual harassment and prior sexual trauma among African-American and white American women.

This study examined the relationship between sexual harassment in work, educational, and social settings and sexual abuse in childhood and/or adulthood in a stratified community sample of 248 African-American and white American women. The cumulative impact of sexual victimization on women's sense of general well-being was also examined. Those most likely to be sexually harassed in work and social settings were women with contact sexual abuse histories, regardless of ethnicity. The work status of harassers of women with sexual abuse histories differed significantly by ethnic group. Although women with prior sexual abuse experiences from both ethnic groups most frequently reported a response to sexual harassment at work, they least frequently did so in social settings. A history of childhood sexual abuse was more negatively associated with African- American women's well-being than were repeated experiences of sexual violence. Future research should address the implications of ethnic and cultural issues on the cumulative impact of incidents of sexual violence on women of color.

Feminist identity among women and men from four ethnic groups.

Robnett, Rachael D; Anderson, Kristin J

2017-01-01

Multiracial feminist theory proposes that the meaning of feminism and the pathways to feminist identity may differ on the basis of cross-cutting social categories such as ethnicity and gender. However, there is currently little research that has included systematic examination of feminist identity among women and men from diverse ethnic backgrounds. We examined feminist orientations among 1,140 undergraduates (70% women) at a Hispanic-Serving Institution who identified as African American, Asian American, European American, or Latina/o. Three related research aims were assessed through a combination of closed- and open-ended questions. First, we examined whether the meaning of the term feminism differed depending on participants' ethnicity or gender. We then tested for ethnic and gender variation in rates of feminist identity. Lastly, we examined participants' reasons for either identifying or not identifying as feminists. Ethnic and gender differences were obtained across each of the 3 research aims. For example, there were significant ethnic differences in rates of feminist identity among women, but not among men. Relative to past research, through the current study, we have provided an especially comprehensive examination of how ethnicity and gender interact to shape feminist attitudes. Consistent with multiracial feminist theory, findings demonstrated that attitudes about feminism vary as a function of both gender and ethnicity, yet key ethnic and gender similarities also emerged.

Esophageal carcinoma is the third most common gastrointestinal malignancy worldwide and is largely unresponsive to therapy. African-Americans have an increased risk for esophageal squamous cell carcinoma (ESCC), the subtype that shows marked variation in geographic frequency. The molecular architecture of African-American ESCC is still poorly understood. It is unclear why African-American ESCC is more aggressive and the survival rate in these patients is worse than those of other ethnic groups. To begin to define genetic alterations that occur in African-American ESCC we conducted microarray expression profiling in pairs of esophageal squamous cell tumors and matched control tissues. We found significant dysregulation of genes encoding drug-metabolizing enzymes and stress response components of the NRF2- mediated oxidative damage pathway, potentially representing key genes in African-American esophageal squamous carcinogenesis. Loss of activity of drug metabolizing enzymes would confer increased sensitivity of esophageal cells to xenobiotics, such as alcohol and tobacco smoke, and may account for the high incidence and aggressiveness of ESCC in this ethnic group. To determine whether certain genes are uniquely altered in African-American ESCC we performed a meta-analysis of ESCC expression profiles in our African-American samples and those of several Asian samples. Down-regulation of TP53 pathway components represented the most common feature in ESCC of all ethnic groups. Importantly, this analysis revealed a potential distinctive molecular underpinning of African-American ESCC, that is, a widespread and prominent involvement of the NRF2 pathway. Taken together, these findings highlight the remarkable interplay of genetic and environmental factors in the pathogenesis of African-American ESCC.

To examine racial/ethnic group differences in adults' reports and ratings of care using data from the National Consumer Assessment of Health Plans (CAHPS) survey Benchmarking Database (NCBD) 1.0. Adult data from the NCBD 1.0 is comprised of CAHPS 1.0 survey data from 54 commercial and 31 Medicaid health plans from across the United States. A total of 28,354 adult respondents (age > or = 18 years) were included in this study. Respondents were categorized as belonging to one of the following racial/ethnic groups: Hispanic (n = 1,657), white (n = 20,414), black or African American (n = 2,942), Asian and Pacific Islander (n = 976), and American Indian or Alaskan native (n = 588). Four single-item global ratings (personal doctor, specialty care, overall rating of health plan, and overall rating of health care) and five multiple-item report composites (access to needed care, provider communication, office staff helpfulness, promptness of care, and health plan customer service) from CAHPS 1.0 were examined. Statistical Analyses. Multiple regression models were estimated to assess differences in global ratings and report composites between whites and members of other racial/ethnic groups, controlling for age, gender, perceived health status, educational attainment, and insurance type. Members of racial/ethnic minority groups, with the exception of Asians/Pacific Islanders, reported experiences with health care similar to those of whites. However, global ratings of care by Asians/Pacific Islanders are similar to those of whites. Improvements in quality of care for Asians/Pacific Islanders are needed. Comparisons of care in racially and ethnically diverse populations based on global ratings of care should be interpreted cautiously.

Muller, Patricia Ann

The purpose of this study was to gain a more complete understanding of the differences in science, mathematics and engineering education among racial-ethnic and gender subgroups by exploring factors related to precollege science achievement growth rates. Using Hierarchical Linear Modeling (HLM) and multi-wave, longitudinal data from the first three waves of the National Education Longitudinal Study of 1988--1994 (NELS:88/94), this study examined precollege science achievement growth rates during the 8th to 10th grade period and the 10th to 12th grade period for African American males, African American females, Latino males, Latina females, Asian American males, Asian American females, White males and White females. For the 8th--10th grade period, previous grades were significantly and positively related to science achievement growth for all subgroups; and socio-economic status and high school program were significantly and positively related to science achievement growth for all subgroups except one (Latino males, and Asian American males respectively). For the 10th--12th grade period, the quantity of science courses completed (science units) was the only variable that was statistically significant for more than one racial-ethnic by gender subgroup. Science units taken were significantly and positively related to 10 th--12th grade growth rates for all racial-ethnic by gender subgroups except Latino males. Locus-of-control was the only cognitive or psychosocial factor included from Eccles, Adler, Futterman, Goff, Kaczala, Meece and Midgley's (1983) theoretical framework for achievement behaviors that appeared to exhibit any pattern across race-ethnicities. Locus-of-control was positively related to 8th--10 th grade science achievement growth for females across all racial-ethnic subgroups, as well as for African American males. However, for both the 8 th--10th grade and 10th--12 th grade periods, there was no consistency across racial-ethnic or gender subgroups in

HLA-A29-POSITIVE BIRDSHOT CHORIORETINOPATHY IN AN AFRICAN AMERICAN PATIENT.

To report the first documented case of HLA-A29-positive birdshot chorioretinopathy in an African American patient. A 51-year-old African American woman presented with a 10-year history of photopsia, progressive decrease in visual acuity, metamorphopsia, and new nyctalopia. Both fundi showed evidence of periphlebitis, arterial attenuation, macular edema, and diffuse chorioretinal atrophy. Fluorescein angiography revealed diffuse vascular leakage, and indocyanine green showed evenly distributed and symmetrical hypofluorescent spots, which were difficult to appreciate on fundoscopy. Workup revealed a positive HLA-A29 and was negative for sarcoid, tuberculosis, and syphilis. Birdshot chorioretinopathy overwhelmingly affects non-Hispanic Caucasians, but there have been rare reported cases in other ethnicities including Hispanics and African Americans. This patient's ethnicity may have contributed to the 10-year delay in diagnosis. To our knowledge, this is the first documented HLA-A29 positive case of birdshot chorioretinopathy in an African American. HLA-A29 may be a useful supportive test in cases with classic clinical presentation in non-Caucasian patients to enable the correct diagnose in a timely manner.

The objective of this study was to examine the relationship between perceived discrimination and psychotic experiences (PE) using validated measures of discrimination and a racially/ethnically diverse population-level sample. Data were drawn from two population-level surveys (The National Latino and Asian American Survey and The National Survey of American Life), which were analyzed together using survey weights and stratification variables. The analytic sample (N=8990) consisted of Latino, Asian, African-American, and Afro-Caribbean adults living in the United States. Separate unadjusted and adjusted multivariable logistic regression models were used, first to examine the crude bivariate relationship between perceived discrimination and PE, and second to examine the relationship adjusting for demographic variables. Adjusted logistic regression models were also used to examine the relationships between perceived discrimination and specific sub-types of PE (auditory and visual hallucinatory experiences, and delusional ideation). When compared to individuals who did not report any discrimination, those who reported the highest levels of discrimination were significantly more likely to report both 12-month PE (Adjusted OR=4.590, pPerceived discrimination is associated with the increased probability of reporting psychotic experiences in a linear Fashion in the US general population.

We have presented nationally representative data on the prevalence and correlates of mental illness and mental health service use among African American and Caribbean Black (US-born and foreign-born) fathers in the United States. We have reported national estimates of lifetime and 12-month prevalence rates of mental illness, correlates, and service use among African American (n = 1254) and Caribbean Black (n = 633) fathers using data from the National Survey of American Life, a national household survey of Black Americans. We used bivariate cross-tabulations and Cox proportional hazards regression approaches and adjusted for the National Survey of American Life's complex sample design. The prevalence of mental illness, sociodemographic correlates, and service use among Black fathers varied by ethnicity and nativity. US-born Caribbean Black fathers had alarmingly high rates of most disorders, including depression, anxiety, and substance disorders. Mental health service use was particularly low for African American and foreign-born Caribbean Black fathers. These results demonstrate the need for more research on the causes and consequences of mental illness and the help-seeking behavior of ethnically diverse Black fathers.

Searching for the Hmong People’s Ethnic Homeland and Multiple Dimensions of Transnational Longing: From the Viewpoint of the Hmong in Laos

Sangmi Lee

2010-01-01

Full Text Available This paper examines how Hmong people in the diaspora imagine each other and develop diverse and multidimensional types of longing in the absence of a “true” ethnic homeland. Even before the Hmong dispersed around the world after the Vietnam War, they never identified or agreed upon a “true” ethnic homeland. As a result, Hmong people have inevitably developed various other types of longing. The objects of these longings have been conceptually expanded to include a Hmong culture, a powerful leader, and a future time when Hmong will again be reunited. In this sense, I will examine the way Hmong people express their perspectives on their objects of longing in the absence of a “true” ethnic homeland by focusing on the viewpoints of some Hmong people residing in Laos. Based on my observations and analysis, I also propose to rethink the limitations of the dominant view about how Hmong imagine their ethnic homeland.Although current theoretical perspectives of transnationalism and “imagined community” have contributed to an understanding of the Hmong people’s imagination and their diasporic ethnic identity, those views cannot fully explain how Hmong people’s longing is not just associated with the lost homeland but can have multiple directions and meanings. These different types of longing expressed by the Hmong people suggest that diasporic communities can be maintainedwithout a territorial ethnic homeland.

Abstract Ethnic minority patients receive lower priority triage assignments in Veteran's Affairs (VA) emergency departments (EDs) compared to White patients, but it is currently unknown whether this disparity arises from generalized biases across the triage assessment process or from differences in how objective and/or subjective institution-level or person-level information is incorporated into the triage assessment process, thus contributing to disparate treatment. The VA database of electronic medical records of patients who presented to the VA ED from 2008 to 2012 was used to measure patient ethnicity, self-reported pain intensity (PI) levels, heart rate (HR), respiratory rate (RR), and nurse-provided triage assignment, the Emergency Severity Index (ESI) score. Multilevel, random effects linear modeling was used to control for demographic and clinical characteristics of patients as well as age, gender, and experience of triage nurses. A total of 359,642 patient/provider encounters between 129,991 VA patients and 774 nurses were included in the study. Patients were 61% non-Hispanic White [NHW], 28% African-American, 7% Hispanic, 2% Asian-American, ESI ratings with lower PI when compared against African-American patients. NHW patients with low to moderate HRs also received higher priority ESI scoring than African-American, Hispanic, Asian-American, and Mixed-ethnicity patients; however, when HR was high NHWs received lower priority ESI ratings than each of the minority groups (except for African-Americans). This study provides evidence for systemic differences in how patients’ vital signs are applied for determining ESI scores for different ethnic groups. Additional prospective research will be needed to determine how this specific person-level mechanism affects healthcare quality and outcomes. PMID:27057847

2013-01-01

Background According to the Office for National Statistics, approximately a quarter of women giving birth in England and Wales are from minority ethnic groups. Previous work has indicated that these women have poorer pregnancy outcomes than White women and poorer experience of maternity care, sometimes encountering stereotyping and racism. The aims of this study were to examine service use and perceptions of care in ethnic minority women from different groups compared to White women. Methods Secondary analysis of data from a survey of women in 2010 was undertaken. The questionnaire asked about women’s experience of care during pregnancy, labour and birth, and the postnatal period, as well as demographic factors. Ethnicity was grouped into eight categories: White, Mixed, Indian, Pakistani, Bangladeshi, Black Caribbean, Black African, and Other ethnicity. Results A total of 24,319 women completed the survey. Compared to White women, women from minority ethnic groups were more likely to be younger, multiparous and without a partner. They tended to access antenatal care later in pregnancy, have fewer antenatal checks, fewer ultrasound scans and less screening. They were less likely to receive pain relief in labour and, Black African women in particular, were more likely to deliver by emergency caesarean section. Postnatally, women from minority ethnic groups had longer lengths of hospital stay and were more likely to breastfeed but they had fewer home visits from midwives. Throughout their maternity care, women from minority ethnic groups were less likely to feel spoken to so they could understand, to be treated with kindness, to be sufficiently involved in decisions and to have confidence and trust in the staff. Conclusion Women in all minority ethnic groups had a poorer experience of maternity services than White women. That this was still the case following publication of a number of national policy documents and local initiatives is a cause for concern. PMID

Full Text Available Abstract Purpose The level of recommended physical activity (PA is met less frequently by people from some ethnic minorities than others. We explored whether these differences in recommended PA between ethnic minority groups and the general population varied by domain and type of culturally-specific activity. Methods Participants were sampled from the population based SUNSET study and were from ethnic Dutch (n = 567, Hindustani-Surinamese (n = 370 and African-Surinamese (n = 689 descent. The validated SQUASH-questionnaire measured PA for the following domains: commuting, occupation, household, leisure time. Culturally-specific activities were added as extra question within the leisure time domain. The effect of each domain on ethnic differences in recommended PA prevalence was examined by odds-ratio (OR analysis through recalculating recommended PA, while, in turn, excluding the contribution of each domain. Results In the ethnic Dutch population, more vigorous PA in commuting and leisure time was reported compared to the Surinamese groups. The Hindustani-Surinamese and African-Surinamese reported more walking as commuting activity, while the Dutch group reported cycling more frequently. Ethnic differences in recommended PA became smaller in both Surinamese groups compared with the Dutch after removing commuting activity, for example, in Hindustani-Surinamese men (OR = 0.92, 95%CI: 0.62-1.37 vs. OR = 1.33, 0.89-2.00 and women (OR = 1.61, 1.12-2.32 vs. OR = 2.03, 1.41-2.92. Removing occupational activity resulted in larger ethnic differences in both groups compared with the Dutch. Smaller effects were found for yoga and dancing, leisure time and household activities. Conclusion This study shows that differences in PA between ethnic minority groups and the general population vary according to the activity domain. The results indicate that including all relevant domains and activities is essential for assessment of ethnic differences in recommended

Afrocentric cultural values and beliefs: movement beyond the race and ethnicity proxy to understand views of diabetes.

The purpose of this study was to estimate the benefit of using a cultural characteristics scale to help diabetes educators understand how African Americans cope with diabetes. Illness representations are influenced by culture. Race and ethnicity as a proxy for culture provides an incomplete understanding of the mechanism by which cultural values influence representations of diabetes. A descriptive correlational design was employed by recruiting hospitalized adults with type 2 diabetes at 3 metropolitan northeast coast sites. The TRIOS Afrocentric cultural characteristics measure and the Illness perception Questionnaire were administered by paper-and-pencil to a diverse sample. Black race and African American ethnicity was used as a proxy for culture and compared to levels of agreement on an Afrocentric cultural scale to determine the relative ability to explain variance in illness representations of diabetes. The TRIOS measure adapted to diabetes care explained variance in illness representations of diabetes, while African American ethnicity/black race was not able to explain variance in illness representations. Clinicians would benefit from considering the degree to which a patient identifies with particular cultural characteristics when tailoring interventions to manipulate illness representations that are not concordant with biomedical representations.

The aim of this study is to explore ethnic variations in psychosocial and health correlates of eating disorders in the United States, Specifically, we compared associations between gender, socioeconomic status (SES), body mass index (BMI), physical and mental self-rated health (SRH), and major depressive disorder (MDD) with eating disorders (EDs) across 10 different ethnic groups in the United States. Data was obtained from the Collaborative Psychiatric Epidemiology Surveys (CPES), a national household probability sample collected in 2001⁻2003. Data for this study included a sample of 17,729 individuals with the following ethnic profile: 520 Vietnamese, 508 Filipino, 600 Chinese, 656 Other Asian, 577 Cuban, 495 Puerto Rican, 1442 Mexican, 1106 Other Hispanic, 4746 African American, and 7587 Non-Latino Whites. Gender, SES (education and income), BMI, SRH, MDD, and presence of EDs were measured across different ethnic groups. Logistic regression analysis was conducted for each ethnic group with lifetime EDs as the main outcome. Ethnic group varied in psychosocial and health correlates of EDs. In most ethnic groups, gender and SES were not associated with EDs. In almost all ethnic groups, EDs were associated with MDD and BMI. EDs were found to be associated with SRH in half of the ethnic groups studied. The associations between gender, SES, BMI, SRH, MDD, and EDs vary across different ethnic groups. These differences must be considered in further studies and in clinical practice in order to improve our approach towards diagnosis and treatment of EDs.

Research has identified several variables that affect utilization of mental health services. However, more could be explored regarding ethnic differences among parents seeking help for their children. In our study, 238 caregivers were recruited from the southern United States to examine ethnic differences in intentions to access child mental health services with the Parental Attitudes Toward Psychological Services Inventory (Turner, 2012) as the primary measure. Group comparisons indicated that African-American parents reported less positive attitudes and more stigma than European-American or Hispanic-American parents. Moderation analyses found (a) attitudes were associated with a higher level of parental help-seeking intention among European Americans, but not among African Americans or Hispanic Americans and (b) stigma was associated with a lower parent-reported likelihood of help-seeking for Hispanic Americans, but not for European Americans or African Americans. Ethnicity deferentially impacts attitudes and stigma associated with seeking mental health services. Public education efforts to increase service use should be tailored toward under-served groups to be more effective. (c) 2015 APA, all rights reserved).

The Impact of Racism on the Sexual and Reproductive Health of African American Women

African American women are disproportionately affected by multiple sexual and reproductive health conditions compared with women of other races/ethnicities. Research suggests that social determinants of health, including poverty, unemployment, and limited education, contribute to health disparities. However, racism is a probable underlying determinant of these social conditions. This article uses a socioecological model to describe racism and its impact on African American women’s sexual and reproductive health. Although similar models have been used for specific infectious and chronic diseases, they have not described how the historical underpinnings of racism affect current sexual and reproductive health outcomes among African American women. We propose a socioecological model that demonstrates how social determinants grounded in racism affect individual behaviors and interpersonal relationships, which may contribute to sexual and reproductive health outcomes. This model provides a perspective to understand how these unique contextual experiences are intertwined with the daily lived experiences of African American women and how they are potentially linked to poor sexual and reproductive health outcomes. The model also presents an opportunity to increase dialog and research among public health practitioners and encourages them to consider the role of these contextual experiences and supportive data when developing prevention interventions. Considerations address the provision of opportunities to promote health equity by reducing the effects of racism and improving African American women’s sexual and reproductive health. PMID:27227533

The current study examined the relationship between substance use references contained in music lyrics and videos and the attitudes and behaviors regarding substance use of White non-Hispanic, African American, and Hispanic emerging adults from a cultivation and social norms framework by assessing 425 male and female college students. It was hypothesized that there would be ethnic variations in perceived harm from substance use and reported recent substance use and that exposure to substance use references contained in music could mediate this relationship. Results confirmed ethnic differences in perceived risk associated with substance use as well as reported substance use with White non-Hispanic college students reporting the least perceived risk and the most substance use. African American college students reported the most perceived risk associated with substance use and the least amount of reported substance use. Results of the Test of Joint Significance confirmed the mediational model in that participant ethnicity was associated with exposure to substance use references in music lyrics and music videos. Substance use references in music lyrics, then, was able to predict actual reported substance use of participants but not perceived risk associated with substance use.

Recovery narratives describe the culturally shared understandings about the ideal or desirable way to recover from an illness experience. This paper examines ethnic differences in recovery narratives among women participating in breast cancer support groups in Central Florida, USA. It compares groups serving African-American, Latina, and European American women, with the objective of better understanding the appeal of ethnic-specific illness support groups for culturally diverse populations. A mixed-method study design combined qualitative and quantitative measures, including in-depth interviews, participant observation at support group meetings, collection of printed documents, and a structured survey. Core elements of the recovery narrative drew from the dominant societal cancer discourse of optimism and personal transformation through adversity; however, important ethnic differences were evident in the meaning assigned to these themes. Groups gave distinctive salience to themes of faith and spirituality, empowerment through the migration experience, and becoming a better person through the journey of recovery. The findings suggest that ethnic cancer support groups draw upon dominant societal discourses about cancer, but they espouse distinctive recovery narratives that are consonant with the groups' cultural models of illness. Similarity between ethnic members' individual recovery narratives and that of the group may contribute to the appeal of ethnic illness support groups for culturally diverse populations.

Schizophrenia is a disabling clinical syndrome found across the world. While the incidence and clinical expression of this illness are strongly influenced by ethnic factors, it is unclear whether patients from different ethnicities show distinct brain deficits. In this multicentre study, we used structural Magnetic Resonance Imaging to investigate neuroanatomy in 126 patients with first episode schizophrenia who came from 4 ethnically distinct cohorts (White Caucasians, African-Caribbeans, Japanese, and Chinese). Each patient was individually matched with a healthy control of the same ethnicity, gender, and age (±1 year). We report a reduction in the gray matter volume of the right anterior insula in patients relative to controls (P ethnic groups despite differences in psychopathology, exposure to antipsychotic medication and image acquisition sequence. This finding provides evidence for a neuroanatomical signature of schizophrenia expressed above and beyond ethnic variations in incidence and clinical expression. In light of the existing literature, implicating the right anterior insula in bipolar disorder, depression, addiction, obsessive-compulsive disorder, and anxiety, we speculate that the neuroanatomical deficit reported here may represent a transdiagnostic feature of Axis I disorders. © The Author 2015.

Numerous facial photogrammetric studies have been published around the world. We aimed to critically review these studies so as to establish population norms for various angular and linear facial measurements; and to determine inter-ethnic/racial facial variations. A comprehensive and systematic search of PubMed, ISI Web of Science, Embase, and Scopus was conducted to identify facial photogrammetric studies published before December, 2014. Subjects of eligible studies were either Africans, Asians or Caucasians. A Bayesian hierarchical random effects model was developed to estimate posterior means and 95% credible intervals (CrI) for each measurement by ethnicity/race. Linear contrasts were constructed to explore inter-ethnic/racial facial variations. We identified 38 eligible studies reporting 11 angular and 18 linear facial measurements. Risk of bias of the studies ranged from 0.06 to 0.66. At the significance level of 0.05, African males were found to have smaller nasofrontal angle (posterior mean difference: 8.1°, 95% CrI: 2.2°-13.5°) compared to Caucasian males and larger nasofacial angle (7.4°, 0.1°-13.2°) compared to Asian males. Nasolabial angle was more obtuse in Caucasian females than in African (17.4°, 0.2°-35.3°) and Asian (9.1°, 0.4°-17.3°) females. Additional inter-ethnic/racial variations were revealed when the level of statistical significance was set at 0.10. A comprehensive database for angular and linear facial measurements was established from existing studies using the statistical model and inter-ethnic/racial variations of facial features were observed. The results have implications for clinical practice and highlight the need and value for high quality photogrammetric studies.

Barajas-Gonzalez, R Gabriela; Brooks-Gunn, Jeanne

2014-12-01

Family and neighborhood influences related to low-income were examined to understand their association with harsh parenting among an ethnically diverse sample of families. Specifically, a path model linking household income to harsh parenting via neighborhood disorder, fear for safety, maternal depressive symptoms, and family conflict was evaluated using cross-sectional data from 2,132 families with children ages 5-16 years from Chicago. The sample was 42% Mexican American, 41% African American, and 17% European American. Results provide support for a family process model where a lower income-to-needs ratio is associated with higher reports of neighborhood disorder, greater fear for safety, and more family conflict, which is in turn, associated with greater frequency of harsh parenting. Our tests for moderation by ethnicity/immigrant status, child gender, and child age (younger child vs. adolescent) indicate that although paths are similar for families of boys and girls, as well as for families of young children and adolescents, there are some differences by ethnic group. Specifically, we find the path from neighborhood disorder to fear for safety is stronger for Mexican American (United States born and immigrant) and European American families in comparison with African American families. We also find that the path from fear for safety to harsh parenting is significant for European American and African American families only. Possible reasons for such moderated effects are considered.

In the United States, Puerto Ricans and African Americans have lower prevalence of breastfeeding and worse clinical outcomes for asthma compared with other racial/ethnic groups. We hypothesize that the history of breastfeeding is associated with increased forced expiratory volume in 1 second (FEV 1 ) % predicted and reduced asthma exacerbations in Latino and African American youths with asthma. As part of the Genes-environments & Admixture in Latino Americans (GALA II) Study and the Study of African Americans, asthma, Genes & Environments (SAGE II), we conducted case-only analyses in children and adolescents aged 8-21 years with asthma from four different racial/ethnic groups: African Americans (n = 426), Mexican Americans (n = 424), mixed/other Latinos (n = 255), and Puerto Ricans (n = 629). We investigated the association between any breastfeeding in infancy and FEV 1 % predicted using multivariable linear regression; Poisson regression was used to determine the association between breastfeeding and asthma exacerbations. Prevalence of breastfeeding was lower in African Americans (59.4%) and Puerto Ricans (54.9%) compared to Mexican Americans (76.2%) and mixed/other Latinos (66.9%; p asthma exacerbations (p = 0.03) in African Americans only. Breastfeeding was associated with higher FEV 1 % predicted in asthma and reduced number of asthma exacerbations in African American youths, calling attention to continued support for breastfeeding.

Full Text Available Abstract Background The population in Norway has become multi-ethnic due to migration from Asia and Africa over the recent decades. The aim of the present study was to explore differences in the self-reported prevalence of cardiovascular disease (CVD and associated risk factors by diabetes status in five ethnic minority groups compared to ethnic Norwegians. Methods Pooled data from three population-based cross-sectional studies conducted in Oslo between 2000 and 2002 was used. Of 54,473 invited individuals 24,749 (45.4% participated. The participants self-reported health status, underwent a clinical examination and blood samples were drawn. A total of 17,854 individuals aged 30 to 61 years born in Norway, Sri-Lanka, Pakistan, Iran, Vietnam or Turkey were included in the study. Chi-square tests, one-way ANOVAs, ANCOVAs, multiple and logistic regression were used. Results Age- and gender-standardized prevalence of self-reported CVD varied between 5.8% and 8.2% for the ethnic minority groups, compared to 2.9% among ethnic Norwegians (p Conclusions Ethnic differences in the prevalence of CVD were prominent for individuals without diabetes. Primary CVD prevention including identification of undiagnosed diabetes should be prioritized for ethnic minorities without known diabetes.

Historical and cultural experiences have shaped the life experiences of cultural communities in Trinidad and Tobago. Using a cultural focus, the goal of this investigation was to examine ethnic variations both in the prevalence of common mental disorder (CMD) symptoms as well as in the associations between sociodemographic, psychosocial, physical health correlates and CMDs among mothers in Trinidad and Tobago. Participants included 1002 mothers (359 African-, 353 Indo- and 290 Mixed-Ethnic Trinidadian). Mean comparisons indicated similarities in the levels of depression, somatisation and anxiety across ethnic groups. The associations between physical ill health, experiences of pain and depression and between physical ill health and somatisation were stronger for Mixed-Ethnic Trinidadian than Indo-Trinidadian mothers. The relationship between early experiences of domestic violence and depression was stronger for Indo-Trinidadian than Mixed-Ethnic Trinidadian mothers. The associations between early experiences of domestic violence and depression and between experiences of pain and somatisation were stronger for African Trinidadian than Mixed-Ethnic Trinidadian mothers. Thus beyond the direct effects, mothers belonging to specific ethnic groups indicated greater or lesser vulnerabilities to CMDs depending on their exposure to specific correlates. Results have applicability for the development of culturally sensitive interventions for mothers experiencing CMDs. © 2016 International Union of Psychological Science.

This research explored mechanisms of vowel variation in African American English by comparing 2 geographically distant groups of African American and White American English speakers for participation in the African American Shift and the Southern Vowel Shift. Thirty-two male (African American: n = 16, White American controls: n = 16) lifelong residents of cities in eastern and western North Carolina produced heed,hid,heyd,head,had,hod,hawed,whod,hood,hoed,hide,howed,hoyd, and heard 3 times each in random order. Formant frequency, duration, and acoustic analyses were completed for the vowels /i, ɪ, e, ɛ, æ, ɑ, ɔ, u, ʊ, o, aɪ, aʊ, oɪ, ɝ/ produced in the listed words. African American English speakers show vowel variation. In the west, the African American English speakers are participating in the Southern Vowel Shift and hod fronting of the African American Shift. In the east, neither the African American English speakers nor their White peers are participating in the Southern Vowel Shift. The African American English speakers show limited participation in the African American Shift. The results provide evidence of regional and socio-ethnic variation in African American English in North Carolina.

To determine the pharmacokinetics and safety of orally administered voriconazole in African grey parrots. 20 clinically normal Timneh African grey parrots (Psittacus erithacus timneh). In single-dose trials, 12 parrots were each administered 6, 12, and 18 mg of voriconazole/kg orally and plasma concentrations of voriconazole were determined via high-pressure liquid chromatography. In a multiple-dose trial, voriconazole (18 mg/kg) was administered orally to 6 birds every 12 hours for 9 days; a control group (2 birds) received tap water. Treatment effects were assessed via observation, clinicopathologic analyses (3 assessments), and measurement of trough plasma voriconazole concentrations (2 assessments). Voriconazole's elimination half-life was short (1.1 to 1.6 hours). Higher doses resulted in disproportional increases in the maximum plasma voriconazole concentration and area under the curve. Trough plasma voriconazole concentrations achieved in the multiple-dose trial were lower than those achieved after administration of single doses. Polyuria (the only adverse treatment effect) developed in treated and control birds but was more severe in the treatment group. In African grey parrots, voriconazole has dose-dependent pharmacokinetics and may induce its own metabolism. Oral administration of 12 to 18 mg of voriconazole/kg twice daily is a rational starting dose for treatment of African grey parrots infected with Aspergillus or other fungal organisms that have a minimal inhibitory concentration for voriconazole treatment. Safety and efficacy of various voriconazole treatment regimens in this species require investigation.

It is an axiom of social gerontology that populations of older individuals become increasingly differentiated as they age. Adaptations to physical and social losses and the increased dependency that typically accompany greater age are likely to be similarly heterogeneous, with different individuals adjusting to the aging process in widely diverse ways. In this paper we consider how individuals with diverse emotional and regulatory profiles, different levels of religiosity, and varied patterns of social relatedness fare as they age. Specifically, we examine the relation between ethnicity and patterns of socioemotional adaptation in a large, ethnically diverse sample (N = 1118) of community-dwelling older adults. Cluster analysis was applied to 11 measures of socioemotional functioning. Ten qualitatively different profiles were extracted and then related to a measure of physical resiliency. Consistent with ethnographic and psychological theory, individuals from different ethnic backgrounds were unevenly distributed across the clusters. Resilient participants of African descent (African Americans, Jamaicans, Trinidadians, Barbadians) were more likely to manifest patterns of adaptation characterized by religious beliefs, while resilient US-born Whites and Immigrant Whites were more likely to be resilient as a result of non-religious social connectedness. Taken together, although these data underscore the diversity of adaptation to later life, we suggest that patterns of successful adaptation vary systematically across ethnic groups. Implications for the continued study of ethnicity in aging and directions for future research are given.

The research on binge eating has overwhelmingly focused on Whites. We aimed to study gender and ethnic differences in the association between body image dissatisfaction and binge eating in a nationally representative sample of Black adults in the USA. This cross-sectional study used data from the National Survey of American Life (NSAL), 2003-2004. Self-identified Caribbean Black (n = 1621) and African American (3570) adults aged 18 and older were enrolled. The independent variable was body dissatisfaction measured with two items. Using the World Health Organization Composite International Diagnostic Interview (WHO-CIDI), outcome was lifetime binge eating without hierarchy according to the DSM-IV criteria. Covariates included age, socioeconomic factors (i.e., education and marital status), and body mass index. Ethnicity and gender were focal moderators. Logistic regressions were used for data analysis. Despite comparable prevalence of lifetime binge eating (5 vs 4 %, p > 0.05), African Americans reported higher body image dissatisfaction than Caribbean Blacks (36 vs 29 %, p > 0.05). In the pooled sample, body dissatisfaction was a strong predictor of lifetime binge eating disorders. There was a significant interaction (p = 0.039) between ethnicity and body image dissatisfaction on binge eating, suggesting a stronger association between body image dissatisfaction and lifetime binge eating for Caribbean Blacks (OR = 11.65, 95 % 6.89-19.72) than African Americans (OR = 6.72, 95 % CI 3.97-11.37). Gender did not interact with body image dissatisfaction on binge eating. Ethnic variation in the link between body image dissatisfaction and binge eating may be due to within-race cultural differences in body image between African Americans and Caribbean Blacks. This may include different definitions, norms, and expectations regarding the body size. Findings suggest that ethnicity may bias relevance of body image dissatisfaction as a diagnostic criterion for

Although there is a vast amount of literature on differences in the perceived experiences of general health care among different racial/ethnic groups, few studies have examined the relationship between race/ethnicity and perceptions of mental health care. The purpose of this study was to determine whether non-Hispanic African Americans and Hispanics had more negative (or less positive) perceptions of the mental health treatment they receive compared to non-Hispanic Whites. Data were from the 1998-2006 Florida Health Services Surveys. The findings indicated that African Americans and Hispanics were less likely than Whites to have favorable perceptions of the mental health care services they received, even after adjusting for demographic and health status variables. Interventions should be designed to address disparities in mental health treatment and the perceptions of such treatment. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

African Americans (OR = 2.50; P < .001) and Hispanics were more likely to endorse trying to cut back (Criterion 3) (OR = 2.01; P < .01). African Americans were more likely to endorse the suffering losses (OR = 2.27; P < .01) criterion. Young adults were more likely to endorse chasing losses (Criterion 9) (OR = 1.81; P < .01) while older adults were less likely to endorse this criterion (OR = 0.76; P < .05). Further research is needed to identify factors contributing to DIF, address criteria level bias, and examine differential test functioning.

Cancer of the lung is the most frequent cancer in the world, but with wide geographical variation in risk. It is most spread among males of all races worldwide, the only exception being its incidence among Chinese women aged 70 years and older. When comparing the different ethnic groups we have to consider that besides inhaling cigarette smoke actively or as a passive smoker the exposure to occupational carcinogens varies considerably according to different work places. In our study we compared 10 years of data from African-Americans in Howard University Hospital, Washington D.C. with 20 years of data from the white population in the University Hospital of Vienna, Austria. Ethnic patterns are generally consistent within each group in terms of both incidence and mortality. The difference in susceptibility between the sexes, the three major racial groups and already proven differences in genetic variations indicate the difference between individuals concerning the initiation and progression of lung cancer.

Epidemiological evidence suggests risk for psychosis varies with ethnicity in Western countries. However, there is little evidence to date on the cross-cultural validity of screening instruments used for such comparisons. Combining two existing UK population-based cohorts, we examined risk for reporting psychotic symptoms across White British (n = 3467), White Irish (n = 851), Caribbean (n = 1899), Indian (n = 2590), Pakistani (n = 1956) and Bangladeshi groups (n = 1248). We assessed the psychometric properties of the Psychosis Screening Questionnaire (PSQ) with a multiple-group confirmatory factor analysis, assessing the equivalence of factor loadings, response thresholds and residual variances in an analysis of measurement non-invariance. Compared with prevalence among British Whites (5.4%), the prevalence of self-reported psychotic symptoms was greater in the Caribbean group (12.7%, adjusted OR = 2.38 [95% CI 1.84-3.07]). Prevalence was also increased among Pakistani individuals (8.3%, adjusted OR = 1.36 [1.01-1.84]) although this difference was driven by a greater likelihood of reporting paranoid symptoms. PSQ items for thought interference, strange experience and hallucination were measured in equivalent ways across ethnic groups. However, our measurement models suggested that paranoid symptoms were measured less reliably among ethnic minorities than among British Whites and appeared to exaggerate latent differences between Pakistani and White British groups when measurement non-invariance was not accounted for. Notwithstanding evidence for measurement non-invariance, the greater risk for reporting psychotic symptoms among Caribbean individuals is unlikely to be an artefact of measurement. Greater residual variance in the recording of paranoid symptoms among ethnic minority respondents warrants caution in using this item to investigate ethnic variation in psychosis risk.

Telomere length is a marker of biological aging that has been linked to cardiovascular disease risk. The black South African population is witnessing a tremendous increase in the prevalence of cardiovascular disease, part of which might be explained through urbanization. We compared telomere length between black South Africans and white South Africans and examined which biological and psychosocial variables played a role in ethnic difference in telomere length. We measured leukocyte telomere length in 161 black South African teachers and 180 white South African teachers aged 23 to 66 years without a history of atherothrombotic vascular disease. Age, sex, years having lived in the area, human immunodeficiency virus (HIV) infection, hypertension, body mass index, dyslipidemia, hemoglobin A1c, C-reactive protein, smoking, physical activity, alcohol abuse, depressive symptoms, psychological distress, and work stress were considered as covariates. Black participants had shorter (median, interquartile range) relative telomere length (0.79, 0.70-0.95) than did white participants (1.06, 0.87-1.21; p < .001), and this difference changed very little after adjusting for covariates. In fully adjusted models, age (p < .001), male sex (p = .011), and HIV positive status (p = .023) were associated with shorter telomere length. Ethnicity did not significantly interact with any covariates in determining telomere length, including psychosocial characteristics. Black South Africans showed markedly shorter telomeres than did white South African counterparts. Age, male sex, and HIV status were associated with shorter telomere length. No interactions between ethnicity and biomedical or psychosocial factors were found. Ethnic difference in telomere length might primarily be explained by genetic factors.

The African-American-white mortality gap for males in the United States is 6 years in favor of whites. Participation in professional sport may moderate this ethnic disparity. The historical cohort of professional basketball players, with nearly equal numbers of African-American and white players, can provide a natural experiment that may control for the classic confounders of income, education, socioeconomic status (SES), and physical factors related to mortality. The objectives of this study are to assess mortality and calculate survival for the overall study population and within ethnicity. Data were combined from several publicly available sources. The cohort was analyzed to compare longevity among all players, and for players stratified by ethnicity, with the general U.S. population. The final dataset included 3366 individuals, of whom 56.0% were African American. Results suggest white players live 18 months longer than their African-American colleagues. African-American players gained 9 years on their respective referent and live longer than white men in the general public. After controlling for covariates, we found that African-American players have a 75% increased risk of death compared with white players, a statistically significant gap (p gap for males is largely ameliorated (1.5 years vs. 6.1 years) in professional basketball but still persists.

Background The population in Norway has become multi-ethnic due to migration from Asia and Africa over the recent decades. The aim of the present study was to explore differences in the self-reported prevalence of cardiovascular disease (CVD) and associated risk factors by diabetes status in five ethnic minority groups compared to ethnic Norwegians.

Results Age- and gender-standardized prevalence of self-reported CVD varied between 5.8% and 8.2% for the ethnic minority groups, compared to 2.9% among ethnic Norwegians (p Corresponding CVD prevalence rates among individuals with diabetes were 15.3% vs. 12.6% (p = 0.364). For individuals without diabetes, the odds ratio (OR) for CVD in the ethnic minority groups remained significantly higher (range 1.5-2.6) than ethnic Norwegians (p employment, and body height, except for Turkish individuals. Regardless of diabetes status, obesity and physical inactivity were prevalent in the majority of ethnic minority groups, whereas systolic- and diastolic- blood pressures were higher in Norwegians. In nearly all ethnic groups, individuals with diabetes had higher triglycerides, waist-to-hip ratio (WHR), and body mass index compared to individuals without diabetes. Age, diabetes, hypertension, hypercholesterolemia, and WHR were significant predictors of CVD in both ethnic Norwegians and ethnic minorities, but significant ethnic differences were found for age, diabetes, and hypercholesterolemia.

Body mass index (BMI) (weight per height 2 ) is the most widely used marker of childhood obesity and total body fatness (BF). However, its validity is limited, especially in children of South Asian and Black African origins. We aimed to quantify BMI adjustments needed for UK children of Black African and South Asian origins so that adjusted BMI related to BF in the same way as for White European children. We used data from four recent UK studies that made deuterium dilution BF measurements in UK children of White European, South Asian and Black African origins. A height-standardized fat mass index (FMI) was derived to represent BF. Linear regression models were then fitted, separately for boys and girls, to quantify ethnic differences in BMI-FMI relationships and to provide ethnic-specific BMI adjustments. We restricted analyses to 4-12 year olds, to whom a single consistent FMI (fat mass per height 5 ) could be applied. BMI consistently underestimated BF in South Asians, requiring positive BMI adjustments of +1.12 kg m - 2 (95% confidence interval (CI): 0.83, 1.41 kg m - 2 ; PAfricans, requiring negative BMI adjustments for Black African children. However, these were complex because there were statistically significant interactions between Black African ethnicity and FMI (P=0.004 boys; P=0.003 girls) and also between FMI and age group (PAfricans. Ethnic-specific adjustments, increasing BMI in South Asians and reducing BMI in Black Africans, can improve the accuracy of BF assessment in these children.

Racial and ethnic minority college students' stigma associated with seeking psychological help: Examining psychocultural correlates.

2013-01-01

Many college students underuse professional psychological help for mental health difficulties. The stigma associated with seeking such help appears to be one of the reasons for this underuse. Levels of psychological distress and past use of counseling/psychotherapy have been found to be important correlates of stigma associated with seeking psychological help (Obasi & Leong, 2009; Vogel, Wade, & Haake, 2006). For racial and ethnic minorities, the hindering effects of self-stigma and perceived stigmatization by others on treatment seeking may further be compounded by their relationships with their own ethnic groups, with other ethnic groups, and with the dominant society. This study used structural equation modeling (SEM) to test a model that explored the effects of psychological distress and psychocultural variables (i.e., ethnic identity, other-group orientation, perceived discrimination) on perceived stigmatization by others and self-stigma for seeking psychological help, controlling for past use of counseling/psychotherapy. The sample consisted of 260 African American, 166 Asian American, and 183 Latino American students. SEM multigroup analyses indicated measurement invariance, but partial structural invariance, across racial/ethnic groups. Across all 3 groups, higher levels of psychological distress and perceived racial/ethnic discrimination, respectively, predicted higher levels of perceived stigmatization by others for seeking psychological help, which, in turn, predicted greater self-stigma for seeking psychological help. Higher levels of other-group orientation predicted lower levels of self-stigma of seeking psychological help across groups. Higher levels of ethnic identity predicted lower levels of self-stigma of seeking psychological help only for African Americans. Implications for research and practice are discussed.

Full Text Available The aim of this study is to explore ethnic variations in psychosocial and health correlates of eating disorders in the United States, Specifically, we compared associations between gender, socioeconomic status (SES, body mass index (BMI, physical and mental self-rated health (SRH, and major depressive disorder (MDD with eating disorders (EDs across 10 different ethnic groups in the United States. Data was obtained from the Collaborative Psychiatric Epidemiology Surveys (CPES, a national household probability sample collected in 2001–2003. Data for this study included a sample of 17,729 individuals with the following ethnic profile: 520 Vietnamese, 508 Filipino, 600 Chinese, 656 Other Asian, 577 Cuban, 495 Puerto Rican, 1442 Mexican, 1106 Other Hispanic, 4746 African American, and 7587 Non-Latino Whites. Gender, SES (education and income, BMI, SRH, MDD, and presence of EDs were measured across different ethnic groups. Logistic regression analysis was conducted for each ethnic group with lifetime EDs as the main outcome. Ethnic group varied in psychosocial and health correlates of EDs. In most ethnic groups, gender and SES were not associated with EDs. In almost all ethnic groups, EDs were associated with MDD and BMI. EDs were found to be associated with SRH in half of the ethnic groups studied. The associations between gender, SES, BMI, SRH, MDD, and EDs vary across different ethnic groups. These differences must be considered in further studies and in clinical practice in order to improve our approach towards diagnosis and treatment of EDs.

Full Text Available Asian American children and adolescents are an under-investigated subpopulation in obesity research. This study aimed to identify specific profiles of Asian subgroups at high risk of adolescent overweight with special attention to Asian ethnicity, socioeconomic status (SES, and their interaction. Multiple logistic regression models were fitted using a sample of 1533 Asian American adolescents ages 12–17 from the 2007–2012 California Health Interview Survey (CHIS. In addition to Asian ethnicity and socioeconomic status (assessed by family income and parental education level, age, gender, nativity, and two lifestyle variables, fast food consumption and physical activity, were also controlled for in these models. Key predictors of overweight in Asian American adolescents included certain Asian ethnicities (Southeast Asian, Filipino, and mixed ethnicities, low family income (<300% of the Federal Poverty Level, and being male. Multiplicative interaction terms between low family income and two ethnicities, Southeast Asian and Vietnamese that had the lowest SES among Asian ethnic groups, were significantly associated with greatly elevated odds of being overweight (ORs = 12.90 and 6.67, respectively. These findings suggest that high risk of overweight in Asian American adolescents associated with low family incomes may be further elevated for those in low-income ethnic groups. Future research might investigate ethnic-group SES as a meaningful indicator of community-level socioeconomic disparities that influence the health of Asian Americans.

Corporal Punishment and Child Aggression: Ethnic-Level Family Cohesion as a Moderator.

Lee, Yoona; Watson, Malcolm W

2017-04-01

Ethnicity has been examined as a putative moderator between parents' use of corporal punishment and children's externalizing behaviors. Yet, the reasons for this potential ethnic-level moderator have not been fully examined. The primary objective of this study was to examine whether the effect of corporal punishment on aggression is ethnic-specific using major racial groups inside and outside the U.S. samples and how the mean levels of cohesion in family relationships as found in different ethnic groups moderate the association between mothers' use of corporal punishment and children's aggression. A total of 729 mothers who had children aged 7 to 13 years were sampled from five ethnic groups (i.e., European American, African American, Hispanic American, Korean, and Chinese). Several hypotheses were tested to examine the moderating effect of ethnic-level, family cohesion on the relation of corporal punishment to children's aggression. As expected, the mean level of family cohesion was significantly different across ethnicities. Consistent results across parallel multilevel and fixed effect models showed that high corporal punishment was associated with more aggression in all ethnicities, but there was a significant variation in the association across ethnicities, and the variation was explained by ethnic-level family cohesion. There were weaker associations between corporal punishment and child aggression among ethnic groups with high family cohesion and stronger associations among ethnic groups with low family cohesion. Ethnic/cultural variation in this study emphasizes the importance of understanding family environment of diverse ethnic groups when evaluating the influence of corporal punishment on child behavior in different ethnic/cultural contexts.

This is the first book by an author in the UK to take an in-depth look at colourism - the process of discrimination based on skin tone among members of the same ethnic group, whereby lighter skin is more valued than darker complexions. The African Diaspora in Britain is examined as part of a global black community with shared experiences of slavery, colonization and neo-colonialism. The author traces the evolution of colourism within African descendant communities in the USA, Jamaica, Latin A...

To examine the association between race/ethnicity, perineal length and the risk of perineal laceration. This is a prospective cohort study of a diverse group of women with singleton gestations in the third trimester of pregnancy. Perineal length was measured and mean values calculated for several racial/ethnic groups. Chi-squared analyses were used to examine rates of severe perineal laceration (third or fourth degree laceration) by race/ethnicity among women considered to have a short perineal length. Further, subgroup analyses were performed comparing nulliparas to multiparas. Among 344 study participants, there was no statistically significant difference in mean perineal length by race/ethnicity (White 4.0 ± 1.1 cm, African-American 3.7 ± 1.0 cm, Latina 4.1 ± 1.1 cm, Asian 3.8 ± 1.0 cm, and other/unknown 4.0 ± 0.9 cm). Considering parity, more multiparous Asian and African-American women had a short perineal length (20.7 and 23.5%, respectively, p = 0.05). Finally, the rate of severe perineal lacerations in our cohort was 2.6% overall, but was 8.2% among Asian women (p = 0.04). We did not find a relationship between short perineal length and risk of severe perineal laceration with vaginal delivery, or a difference in mean perineal length by maternal race/ethnicity. However, we did find that women of different racial/ethnic groups have varying rates of severe perineal laceration, with Asian women comprising the highest proportion.

To investigate the clinical characteristics, treatment, medication use, and treatment response in patients with ulcerative colitis (UC) across ethnic groups. This study retrospectively analyzed medical records of all 268465 patients who visited the Bumrungrad International Digestive Disease Center during 2005-2010. The demographics, clinical characteristics, medication use, results of investigations, and medical and surgical management for patients with UC were evaluated. Evaluation included sigmoidoscopy and colonoscopy performed in compliance with the American Society of Gastrointestinal Endoscopy practice guidelines. Patient ethnicities were categorized into seven groups: Thai, Oriental, South Asian (SA), Middle Eastern (ME), Caucasian, African, and Hispanic. UC pathological severity was classified into inactive, mild, moderate, and severe. Associations between categorical variables were analyzed using the χ(2) or Fischer's exact test. Associations between categorical and interval variables were analyzed using Student's t-test and/or analysis of covariance. UC was diagnosed in 371 of the 268465 patients: male 56.33%; ME 42%, Caucasian 23%, and Thai 19%. Annual incidence of UC was 82 cases per 100000 with wide ethnic variation, ranging from 29 to 206 cases per 100000 in Oriental and ME patients, respectively. Of the patients with UC, 16.71% had severe UC with highest incidence among the patients from ME (20.39%) and lowest among the Caucasian population (11.90%). ME had highest proportion of pancolitis (52.90%), followed by Caucasian (45.35%) and Asian (34.40%). Only 20.93% of Caucasian patients received steroid, compared with 26.40% and 27.10% of Asian and Middle Eastern, respectively (P = 0.732). Overall, 13.72% of UC patients did not respond to steroid therapy, with non-significantly higher proportions of non-responders among Asian and Middle Eastern patients (15.22% and 15.04%, respectively) (P = 0.781). On average, 5.93% underwent surgical management with

HIV prevalence between different ethnic groups within South Africa exhibits considerable variation. Numerous authors believe that elevated sexual partner concurrency rates are important in the spread of HIV. Few studies have, however, investigated if differential concurrency rates could explain differential HIV spread within ethnic groups in South Africa. This ecological analysis, explores how much of the variation in HIV prevalence by ethnic group is explained by differential concurrency rates. Using a nationally representative survey (the South African National HIV Prevalence, HIV Incidence, Behaviour and Communication Survey, 2005) the HIV prevalence in each of eight major ethnic groups was calculated. Linear regression analysis was used to assess the association between an ethnic group's HIV prevalence and the point-prevalence of concurrency. Results showed that HIV prevalence rates varied considerably between South Africa's ethnic groups. This applied to both different racial groups and to different ethnic groups within the black group. The point-prevalence of concurrency by ethnic group was strongly associated with HIV prevalence (R(2) = 0.83; p = 0.001). Tackling the key drivers of high HIV transmission in this population may benefit from more emphasis on partner reduction interventions.

Beliefs concerning the causes of mental illness may help to explain why there are significant disparities in the rates of formal mental health service use among racial/ethnic minority elderly as compared with their white counterparts. This study applies the cultural influences on mental health framework to identify the relationship between race/ethnicity and differences in 1) beliefs on the cause of mental illness, 2) preferences for type of treatment, and 3) provider characteristics. Analyses were conducted using baseline data collected from participants who completed the cultural attitudes toward healthcare and mental illness questionnaire, developed for the Primary Care Research in Substance Abuse and Mental Health for the Elderly study, a multisite randomized trial for older adults (65+) with depression, anxiety, or at-risk alcohol consumption. The final sample consisted of 1,257 non-Latino whites, 536 African Americans, 112 Asian Americans, and 303 Latinos. African Americans, Asian Americans, and Latinos had differing beliefs regarding the causes of mental illness when compared with non-Latino whites. Race/ethnicity was also associated with determining who makes healthcare decisions, treatment preferences, and preferred characteristics of healthcare providers. This study highlights the association between race/ethnicity and health beliefs, treatment preferences, healthcare decisions, and consumers' preferred characteristics of healthcare providers. Accommodating the values and preferences of individuals can be helpful in engaging racial/ethnic minority patients in mental health services.

The purpose of this study was to integrate and validate a multidimensional model of ethnic-racial identity and gender identity borrowing constructs and measures based on social identity and gender identity theories. Participants included 662 emerging adults (M age  = 19.86 years; 75 % female) who self-identified either as Asian American, Latino/a, or White European American. We assessed the following facets separately for ethnic-racial identity and gender identity: centrality, in-group affect, in-group ties, self-perceived typicality, and felt conformity pressure. Within each identity domain (gender or ethnicity/race), the five dimensions generally indicated small-to-moderate correlations with one another. Also, correlations between domains for each dimension (e.g., gender typicality and ethnic-racial typicality) were mostly moderate in magnitude. We also noted some group variations based on participants' ethnicity/race and gender in how strongly particular dimensions were associated with self-esteem. Finally, participants who scored positively on identity dimensions for both gender and ethnic-racial domains indicated higher self-esteem than those who scored high in only one domain or low in both domains. We recommend the application of multidimensional models to study social identities in multiple domains as they may relate to various outcomes during development.

This work aims to explain the complexity of the Knops blood group system in the Chinese population. The Knops blood group system consists of antigens encoded by CR1 gene exon 29. A total of 281 individuals from the Han, Uigur, Tu, Lisu and Dong ethnic groups were studied. The coding region of the CR1 gene of 11 Han donors was analysed using reverse transcription-polymerase chain reaction (PCR) and sequencing. CR1 gene exon 29 in the 39 samples was analysed through genomic DNA sequencing. According to the sequencing result, a PCR-sequence-specific primers system was designed to screen the A4646G and A4870G alleles in the Chinese population. Twelve single nucleotide polymorphisms (SNPs) were observed in the coding region of the CR1 gene in the Han population. Two SNPs (A4646G and A4870G) were detected in the CR1 gene exon 29. The 4646G allele was found only in the Uigur and Tu ethnic groups, in which the allele frequencies were 0·11 and 0·06, respectively. The frequencies of the 4870A allele in the Han, Uigur, Tu, Lisu and Dong ethnic groups were 0·82, 0·83, 0·82, 0·57 and 0·57, respectively. The CR1 gene in the Chinese people is more conservative than that in the Caucasian or African people. Different Chinese ethnic groups may have their own different CR1 gene characteristics. The existence of 4646G in the Uigur and Tu ethnic groups suggests that both may carry certain Caucasian characteristics in the CR1 gene. The frequency of 4870G in the Lisu and Dong ethnic groups implies possible incidence of evolutionary pressure similar to what the Africans had experienced. © 2010 The Authors.

The cyprinid genus Barbus, with more than 800 nominal species, is an apparently polyphyletic assemblage to which a number of unrelated species, groups and/or assemblages have been assigned. It includes species that exhibit three different ploidy levels: diploid, tetraploid and hexaploid. Several lineages of the family Cyprinidae constitute a major component of the African freshwater ichthyofauna, having about 500 species, and fishes assigned to the genus 'Barbus' have the most species on the continent. We used complete sequences of the mitochondrial cytochrome b gene in order to infer phylogenetic relationships between diploid, tetraploid and hexaploid species of 'Barbus' occurring in southern Africa, the only region where representatives of all of the three ploidy levels occur. The results indicate that most of the lineages are incorrectly classified in the genus 'Barbus'. The southern African tetraploids probably originated from southern African diploids. They constitute a monophyletic group distinct from tetraploids occurring in the Euro-Mediterranean region (Barbus sensu stricto). The 'small' African diploid species seem to be paraphyletic, while the 'large' African hexaploid barbs species are of a single, recent origin and form a monophyletic group. The evidence of multiple, independent origins of polyploidy occurring in the African cyprinine cyprinids thus provides a significant contribution to the knowledge on the systematic diversity of these fishes, and warrants a thorough taxonomic reorganization of the genus.

Building upon literature suggesting low Internet use among racial/ethnic minorities and socioeconomically disadvantaged groups, this study examined how race/ethnicity and socioeconomic status (SES) influence the Internet use for health information, addressing both independent and interactive effects. Using data from 17,704 older adults in the California Health Interview Survey, logistic regression models were estimated with race/ethnicity (Whites, African Americans, Latinos, and Asians), SES index, and the interaction between race/ethnicity and SES index. Overall, approximately 40% of participants were Internet-users for health information. Direct effects of race/ethnicity and SES-and their interactions-were all found to be significant. Minority status combined with the lowest levels of SES substantially reduced the odds of using Internet for health information. Findings suggest the combination of racial/ethnic minority status and low SES as a source of digital divide, and provide implications for Internet technology training for the target population.

Sodium restriction is important in the management of heart failure (HF). Although many low-sodium educational resources are available, few are directed specifically at urban African Americans. A registered dietitian prospectively interviewed 50 African-American and 25 white patients in an urban public hospital (derivation cohort) in Dallas, TX, using a food-frequency instrument that listed 146 food choices. Foods >300 mg sodium/serving consumed at least weekly by 50% of an ethnic group were classified as being a high-sodium core food for that group. Classification of foods (core or not core) was validated in a second African-American cohort (n = 144). Five high-sodium food choices were classified as core food in both the derivation and validation African-American cohorts (salt in cooking, canned vegetables, cheese, processed meats, and cold cereal) and another 3 when the derivation and validation cohorts were combined (fast food, fried chicken, and corn bread). Four of these 8 foods were not classified as core foods in whites. Eight high-sodium foods were frequently consumed by southern, urban African Americans with heart failure. Several of these foods were not commonly consumed by whites, emphasizing the need to be sensitive to ethnic differences in dietary habits when educating patients about sodium intake.

Ethnic inequalities in mental health have been found in many high-income countries. The purpose of this study is to test whether mental health inequalities between ethnic groups are mediated by exposure to unfavourable working conditions. Workers (n = 6278) were selected from baseline data of the multi-ethnic HELIUS study. Measures included two indices of unfavourable working conditions (lack of recovery opportunities, and perceived work stress), and two mental health outcomes (generic mental health: MCS-12 and depressive symptoms: PHQ-9). Mediation of the relationships between ethnicity and mental health by unfavourable working conditions was tested using the bias-corrected bootstrap confidence intervals technique. Linear models with and without the mediators included, and adjusted for gender and age. Attenuation was calculated as the change in B between the models with and without mediators. The sample comprised Dutch (1355), African Surinamese (1290), South-Asian Surinamese (1121), Turkish (1090), Ghanaian (729), and Moroccan (693) workers. After controlling for age and gender, all ethnic minorities had a higher risk of mental health problems as compared to the Dutch host population, with the exception of Ghanaians in the case of depressive symptoms, and African Surinamese workers with regard to both outcomes. The Turkish group stands out with the lowest mental health on both mental health indices, followed by Moroccan and South-Asian Surinamese workers. A lack of recovery opportunities mediated the relationship between ethnic group and a higher risk of mental health problems. Perceived work stress did not contribute to the explanation of ethnic inequalities. The higher risk of mental health problems in ethnic minority groups can be partly accounted for by a lack of recovery opportunities at work, but not by perceived work stress. This may imply that workplace prevention targeting recovery opportunities have the potential to reduce ethnic inequalities, but

Full Text Available Women from diverse ethnic/racial backgrounds have higher chronic disease mortality rates when compared to White non-Hispanic women. Community-based programs, such as beauty salons, have been used to reach diverse ethnic/racial women, yet little is known about diverse ethnic/racial women cosmetologists' involvement in health promotion and their health behaviors, which is the purpose of this review. The growing beauty salon health promotion literature indicates that their roles in these studies have been varied, not only as health promoters but also as recruiters, facilitators, and in general major catalysts for investigator-initiated studies. However, the review also identified a major void in the literature in that there were few studies on health behaviors of diverse ethnic/racial women cosmetologists, especially African American women cosmetologists. Recommendations include increasing the capacity of diverse ethnic/racial women cosmetologists as community health leaders and investigating their health status, knowledge, attitudes, and practices.

Examine whether personal identity confusion and ethnic identity, respectively, moderate and/or mediate the relationship between perceived discrimination (PD) and depressive symptoms (DS) in eight ethnic-generational groups. The sample consisted of 9665 students (73% women; mean age 20.31) from 30 colleges and universities from around the United States. Cross-sectional data were gathered through a confidential online survey. Across groups, PD and ethnic identity levels varied, while identity confusion levels were mostly similar. Neither identity confusion nor ethnic identity moderated the PD-DS relationship for any groups. However, identity confusion was a partial mediator for immigrant and nonimmigrant Hispanic/Latino(a) and White/European American participants. Identity confusion also suppressed the PD-DS relationship for Black/African American participants. Results highlight the need for additional research on identity confusion's role in the PD-distress link and the importance of addressing ethnicity and generation status when examining the effects of PD on college students' mental health. © 2012 Wiley Periodicals, Inc.

Full Text Available Background: This study aimed to test if ethnicity moderates the additive effects of lifetime psychiatric disorders on serious suicidal thoughts among a nationally representative sample of Black adults in the United States. Methods: For this study, we used data of 5,181 Black adults (3,570 African Americans and 1,621 Caribbean Blacks who participated in the National Survey of American Life, 2001-2003. Five lifetime psychiatric disorders (i.e., major depressive disorder, general anxiety disorder, post-traumatic stress disorder, alcohol abuse disorder, and drug abuse were considered as the independent variables. Lifetime serious suicidal ideation was considered as the dependent variable. Logistic regressions were used to determine if ethnicity modifies the effects of each psychiatric disorder on serious suicide ideation. Ethnicity was conceptualized as the possible moderator and socio-demographics (i.e., age, gender, education level, employment, marital status and country region were control variables. Results: Among African Americans, major depressive disorder, general anxiety disorder, post-traumatic stress disorder and alcohol abuse disorder were associated with higher odds of suicidal thoughts. Among Caribbean Blacks, major depressive disorder and drug abuse disorder were associated with higher odds of suicidal thoughts. In the pooled sample, there was a significant interaction between ethnicity and anxiety disorder and a marginally significant interaction between ethnicity and drug abuse. Conclusions: Based on our study, suicidality due to psychiatric disorders among Black adults in the United States may depend on ethnicity. General anxiety disorder seems to be a more important risk factor for suicidal ideation among African Americans while drug abuse may contribute more to the risk of suicidal thoughts among Caribbean Blacks.

Nocturnal bruxism is associated with gastroesophageal reflux disease (GERD), and GERD is strongly associated with obstructive sleep apnea (OSA). Gender and ethnic differences in the prevalence and clinical presentation of these often overlapping sleep disorders have not been well documented. Our aim was to examine the associations between, and the symptoms associated with, nocturnal GERD and sleep bruxism in patients with OSA, and to examine the influence of gender and ethnicity. A retrospective chart review was performed of patients diagnosed with OSA at an academic sleep center. The patients completed a sleep questionnaire prior to undergoing polysomnography. Patients with confirmed OSA were evaluated based on gender and ethnicity. Associations were determined between sleep bruxism and nocturnal GERD, and daytime sleepiness, insomnia, restless legs symptoms, and markers of OSA severity in each group. In these patients with OSA, the prevalence of nocturnal GERD (35%) and sleep bruxism (26%) were higher than the general population. Sleep bruxism was more common in Caucasians than in African Americans or Hispanics; there was no gender difference. Nocturnal GERD was similar among all gender and ethnic groups. Bruxism was associated with nocturnal GERD in females, restless legs symptoms in all subjects and in males, sleepiness in African Americans, and insomnia in Hispanics. Nocturnal GERD was associated with sleepiness in males and African Americans, insomnia in females, and restless legs symptoms in females and in Caucasians. Patients with OSA commonly have comorbid sleep bruxism and nocturnal GERD, which may require separate treatment. Providers should be aware of differences in clinical presentation among different ethnic and gender groups.

Seasonal Changes in Sleep Duration in African American and African College Students Living In Washington, D.C.

Full Text Available Duration of nocturnal melatonin secretion, a marker of “biological night” that relates to sleep duration, is longer in winter than in summer in patients with seasonal affective disorder (SAD, but not in healthy controls. In this study of African and African American college students, we hypothesized that students who met criteria for winter SAD or subsyndromal SAD (S-SAD would report sleeping longer in winter than in summer. In addition, based on our previous observation that Africans report more “problems” with change in seasons than African Americans, we expected that the seasonal changes in sleep duration would be greater in African students than in African American students. Based on Seasonal Pattern Assessment Questionnaire (SPAQ responses, African American and African college students in Washington, D.C. (N = 575 were grouped into a winter SAD/S-SAD group or a no winter diagnosis group, and winter and summer sleep length were determined. We conducted a 2 (season × 2 (sex × 2 (ethnicity × 2 (winter diagnosis group ANCOVA on reported sleep duration, controlling for age. Contrary to our hypothesis, we found that African and African American students with winter SAD/S-SAD report sleeping longer in the summer than in the winter. No differences in seasonality of sleep were found between African and African American students. Students with winter SAD or S-SAD may need to sacrifice sleep duration in the winter, when their academic functioning/efficiency may be impaired by syndromal or subsyndromal depression, in order to meet seasonally increased academic demands.

Understanding the risk and protective factors related to maternal mental health problems is important for improving the well-being of mothers and children, particularly in African American populations which may be at greater risk for maternal depression and resulting child behavior problems. This study explored whether three psychosocial resources--emotional resilience, social support, and ethnic identity--serve as protective factors in the face of specific stressful events that may trigger African American mothers' depression and anxiety symptoms. Standard self-report measures of depression, anxiety, negative life events, community violence, abuse, emotional resilience, social support, and ethnic identity were administered to African American mothers (N=209) of 2-18 month-old children. Linear regression models revealed main effects of negative life events and abuse on increased depression and anxiety symptoms, while emotional resilience and social support predicted decreased symptoms. There was also a significant interaction revealing a protective-reactive effect of ethnic identity on the associations of witnessed community violence with depression and anxiety symptoms. It is important for primary care providers to screen African American mothers for negative life events and abuse to identify those at increased risk for maternal depression and anxiety symptoms. Treatment programs should target emotional resilience, enhanced social support, and stronger ethnic group affiliation, which may be most effective at preventing mental health problems among mothers exposed to relative lower levels of community violence.

Racial/ethnic disparities in prevalence and care of patients with type 2 diabetes mellitus.

2015-05-01

As of 2012, nearly 10% of Americans had diabetes mellitus. People with diabetes are at approximately double the risk of premature death compared with those in the same age groups without the condition. While the prevalence of diabetes has risen across all racial/ethnic groups over the past 30 years, rates are higher in minority populations. The objective of this review article is to evaluate the prevalence of diabetes and disease-related comorbidities as well as the primary endpoints of clinical studies assessing glucose-lowering treatments in African Americans, Hispanics, and Asians. As part of our examination of this topic, we reviewed epidemiologic and outcome publications. Additionally, we performed a comprehensive literature search of clinical trials that evaluated glucose-lowering drugs in racial minority populations. For race/ethnicity, we used the terms African American, African, Hispanic, and Asian. We searched PubMed for clinical trial results from 1996 to 2015 using these terms by drug class and specific drug. Search results were filtered qualitatively. Overall, the majority of publications that fit our search criteria pertained to native Asian patient populations (i.e., Asian patients in Asian countries). Sulfonylureas; the α-glucosidase inhibitor, miglitol; the biguanide, metformin; and the thiazolidinedione, rosiglitazone have been evaluated in African American and Hispanic populations, as well as in Asians. The literature on other glucose-lowering drugs in non-white races/ethnicities is more limited. Clinical data are needed for guiding diabetes treatment among racial minority populations. A multi-faceted approach, including vigilant screening in at-risk populations, aggressive treatment, and culturally sensitive patient education, could help reduce the burden of diabetes on minority populations. To ensure optimal outcomes, educational programs that integrate culturally relevant approaches should highlight the importance of risk-factor control in

Dismantling reified African culture through localised homosexualities in Uganda.

Nyanzi, Stella

2013-01-01

Uganda's Anti-Homosexuality Bill of 2009 aimed at protecting the cherished culture of the people against emergent threats to the traditional heterosexual family. The Bill's justification, however, lay in myopic imaginings of a homogenous African-ness and pedestrian oblivion to pluralities within African sexualities. This paper revisits the debate that homosexuality is 'un-African'. Rhetoric analysis of the Anti-Homosexuality Bill exposes how dominant discourses of law, medicine, religion, geography and culture reinforce the view that homosexuality is foreign to Africa. Based on ethnography in contemporary Uganda, I explore how self-identified same-sex-loving individuals simultaneously claim their African-ness and their homosexuality. Their strategies include ethnic belonging, membership to kinship structures, making connections with pre-colonial histories of homosexuality, civic participation in democratic processes, national identity, organising of lesbian, gay, bisexual, transgender, intersex and questioning support groups, language and nomenclature, visibility and voice in local communal activities, solidarity and adherence to cultural rituals. In present-day Uganda, same-sex-loving men, women and transgender people variously assert their African-ness.

Background/Objectives: Body mass index (BMI) (weight per height2) is the most widely used marker of childhood obesity and total body fatness (BF). However, its validity is limited, especially in children of South Asian and Black African origins. We aimed to quantify BMI adjustments needed for UK children of Black African and South Asian origins so that adjusted BMI related to BF in the same way as for White European children. Methods: We used data from four recent UK studies that made deuterium dilution BF measurements in UK children of White European, South Asian and Black African origins. A height-standardized fat mass index (FMI) was derived to represent BF. Linear regression models were then fitted, separately for boys and girls, to quantify ethnic differences in BMI–FMI relationships and to provide ethnic-specific BMI adjustments. Results: We restricted analyses to 4–12 year olds, to whom a single consistent FMI (fat mass per height5) could be applied. BMI consistently underestimated BF in South Asians, requiring positive BMI adjustments of +1.12 kg m−2 (95% confidence interval (CI): 0.83, 1.41 kg m−2; Pchildren. However, these were complex because there were statistically significant interactions between Black African ethnicity and FMI (P=0.004 boys; P=0.003 girls) and also between FMI and age group (Pchildren with higher unadjusted BMI and the smallest in older children with lower unadjusted BMI. Conclusions: BMI underestimated BF in South Asians and overestimated BF in Black Africans. Ethnic-specific adjustments, increasing BMI in South Asians and reducing BMI in Black Africans, can improve the accuracy of BF assessment in these children. PMID:28325931

We investigated the association between a U.S. National Institutes of Health (NIH) R01 applicant’s self-identified race or ethnicity and the probability of receiving an award by using data from the NIH IMPAC II grant database, the Thomson Reuters Web of Science, and other sources. Although proposals with strong priority scores were equally likely to be funded regardless of race, we find that Asians are 4 percentage points and black or African-American applicants are 13 percentage points less likely to receive NIH investigator-initiated research funding compared with whites. After controlling for the applicant’s educational background, country of origin, training, previous research awards, publication record, and employer characteristics, we find that black or African-American applicants remain 10 percentage points less likely than whites to be awarded NIH research funding. Our results suggest some leverage points for policy intervention. PMID:21852498

Our understanding of the influence of maternal race/ethnicity and nativity and childhood autistic disorder (AD) in African Americans/blacks, Asians, and Hispanics in the United States is limited. Phenotypic differences in the presentation of childhood AD in minority groups may indicate etiologic heterogeneity or different thresholds for diagnosis. We investigated whether the risk of developing AD and AD phenotypes differed according to maternal race/ethnicity and nativity. Children born in Los Angeles County with a primary AD diagnosis at ages 3 to 5 years during 1998-2009 were identified and linked to 1995-2006 California birth certificates (7540 children with AD from a cohort of 1,626,354 births). We identified a subgroup of children with AD and a secondary diagnosis of mental retardation and investigated heterogeneity in language and behavior. We found increased risks of being diagnosed with AD overall and specifically with comorbid mental retardation in children of foreign-born mothers who were black, Central/South American, Filipino, and Vietnamese, as well as among US-born Hispanic and African American/black mothers, compared with US-born whites. Children of US African American/black and foreign-born black, foreign-born Central/South American, and US-born Hispanic mothers were at higher risk of exhibiting an AD phenotype with both severe emotional outbursts and impaired expressive language than children of US-born whites. Maternal race/ethnicity and nativity are associated with offspring's AD diagnosis and severity. Future studies need to examine factors related to nativity and migration that may play a role in the etiology as well as identification and diagnosis of AD in children.

Ethnic minority youth are disproportionately affected by substance use-related consequences, which may be best understood through a social ecological lens. Differences in psychosocial consequences between ethnic majority and minority groups are likely due to underlying social and environmental factors. The current longitudinal study examined the outcomes of a school-based motivational enhancement treatment intervention in reducing disparities in substance use consequences experienced by some ethnic minority groups with both between and within-subjects differences. Students were referred to the intervention through school personnel and participated in a four-session intervention targeting alcohol and drug use. Participants included 122 youth aged 13-19 years. Participants were grouped by ethnicity and likelihood of disparate negative consequences of substance use. African American/Hispanic/Multiethnic youth formed one group, and youth identifying as White or Asian formed a second group. We hypothesized that (1) there would be significant disparities in psychosocial, serious problem behavior, and school-based consequences of substance use between White/Asian students compared to African American/Hispanic/Multiethnic students at baseline; (2) physical dependence consequences would not be disparate at baseline; and (3) overall disparities would be reduced at post-treatment follow-up. Results indicated that African American/Hispanic/Multiethnic adolescents demonstrated statistically significant disparate consequences at baseline, except for physical dependency consequences. Lastly, significant reductions in disparities were evidenced between groups over time. Our findings highlight the efficacy of utilizing school-based substance use interventions in decreasing ethnic health disparities in substance use consequences.

African Americans have a higher risk of developing heart failure (HF) than persons from other ethnic groups. Once diagnosed, they have lower rates of HF self-care and poorer health outcomes. Promoting engagement in HF self-care is amenable to change and represents an important way to improve the health of African Americans with HF. This study used a community-based participatory action research methodology called photovoice to explore the practice of HF self-care among low-income, urban, community dwelling African Americans. Using the photovoice methodology, themes emerged regarding self-care management and self-care maintenance.

The purpose of this study was to compare the daily inter- and intra-situational ambulatory blood pressure (BP) variation by ethnicity in women. The African-American (N = 82; Age = 39.7 + 8.9), Hispanic-American (N = 25; age = 37.5 + 9.4), Asian-American (N = 22; Age = 35.2 + 8.6), and European-American (N = 122; Age = 37.2+ 9.4) women in this study all worked in similar positions at two major medical centers in NYC. Each wore an ambulatory monitor during the course of one mid-week workday. Proportional BP changes from work or home to sleep, intra-situational BP variation (standard deviation [SD]) and mean situational BP levels were compared among the groups using ANOVA models. African-American and Asian-American women had significantly smaller proportional work-sleep systolic changes than either European- (P women, but the Asian-American women's changes tended to be smallest. The variability (SD) of diastolic BP at work was significantly greater among African- and Hispanic-American women compared to Asian- and European-American women (all P women had greater sleep variability than European-American women (P Asian-American women had the highest level of sleep diastolic pressure (all comparisons P Asian-American women have an attenuated proportional BP decline from waking environments to sleep compared to European-American and Hispanic-American women. Asian-American nocturnal BP may be elevated relative to all other groups. Am. J. Hum. Biol. 28:932-935, 2016. © 2016Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

This study aims to (a) examine the roles of knowledge, distrust in medical professionals, information sources, and 2 dimensions of religiosity (i.e., religious activity and religious belief) in influencing willingness to participate (WTP) in cancer clinical trials and to (b) compare the results for Caucasians and African Americans in order to inform future recruitment. An online survey was fielded via a Knowledge Networks panel with a nationally representative sample including 478 Caucasians and 173 African Americans. The results showed that distrust in medical professionals was a strong barrier to WTP for both ethnic groups, whereas factual knowledge about trial procedures was not associated with WTP for either ethnic group. Seeking trial information from doctors was positively associated with WTP for Caucasians; seeking trial information from hospitals was positively associated with WTP for African Americans. More interestingly, levels of religious activity negatively predicted WTP for Caucasians but positively predicted WTP for African Americans. Self-reported religious belief was not associated with WTP for either ethnic group. In sum, although distrust is a common barrier to WTP, the influence of preferred information sources and religious activity on WTP varies as a function of ethnicity.

Adolescence is a developmental period marked by increased stress, especially among Black youth. In addition to stress related to their developmental transition, social factors such as a perceived unsafe neighborhood impose additional risks. We examined gender and ethnic differences in the association between perceived neighborhood safety and major depressive disorder (MDD) among a national sample of Black youth. We used data from the National Survey of American Life - Adolescents (NSAL-A), 2003–2004. In total, 1170 Black adolescents entered the study. This number was composed of 810 African American and 360 Caribbean Black youth (age 13 to 17). Demographic factors, perceived neighborhood safety, and MDD (Composite International Diagnostic Interview, CIDI) were measured. Logistic regressions were used to test the association between neighborhood safety and MDD in the pooled sample, as well as based on ethnicity by gender groups. In the pooled sample of Black youth, those who perceived their neighborhoods to be unsafe were at higher risk of MDD (Odds Ratio [OR] = 1.25; 95% Confidence Interval [CI] = 1.02-1.51). The perception that one’s neighborhood is unsafe was associated with a higher risk of MDD among African American males (OR=1.41; 95% CI = 1.03–1.93) but not African American females or Caribbean Black males and females. In conclusion, perceived neighborhood safety is not a universal psychological determinant of MDD across ethnic by gender groups of Black youth; however, policies and programs that enhance the sense of neighborhood safety may prevent MDD in male African American youth.

Genomic sovereignty and the African promise: mining the African genome for the benefit of Africa.

Scientific interest in genomics in Africa is on the rise with a number of funding initiatives aimed specifically at supporting research in this area. Genomics research on material of African origin raises a number of important ethical issues. A prominent concern relates to sample export, which is increasingly seen by researchers and ethics committees across the continent as being problematic. The concept of genomic sovereignty proposes that unique patterns of genomic variation can be found in human populations, and that these are commercially, scientifically or symbolically valuable and in need of protection against exploitation. Although it is appealing as a response to increasing concerns regarding sample export, there are a number of important conceptual problems relating to the term. It is not clear, for instance, whether it is appropriate that ownership over human genomic samples should rest with national governments. Furthermore, ethnic groups in Africa are frequently spread across multiple nation states, and protection offered in one state may not prevent researchers from accessing the same group elsewhere. Lastly, scientific evidence suggests that the assumption that genomic data is unique for population groups is false. Although the frequency with which particular variants are found can differ between groups, such genes or variants per se are not unique to any population group. In this paper, the authors describe these concerns in detail and argue that the concept of genomic sovereignty alone may not be adequate to protect the genetic resources of people of African descent.

The current study compares subjective mental and physical health among native Spaniards and immigrant groups, and examines the effects of ethnicity and perceived discrimination (PD) on subjective health in immigrants. Two random samples of 1250 immigrants to Spain from Colombia, Bolivia, Romania, Morocco, and Sub-Saharan Africa and 500 native Spaniards, aged between 18 and 65, were recruited for this cross-sectional study. Several hierarchical regression analyses of ethnicity and PD on subjective mental and physical health (assessed using the health-related quality of life items, HRQLSF-12) were carried out separately for men and women. Male immigrants from Colombia and Sub-Saharan Africa showed better physical health than natives, controlling for age and socioeconomic and marital status. The immigrants - except for the Colombians - had poorer mental health than natives, especially African men and Bolivian women. Socioeconomic status had no impact on these differences. Among immigrants, PD was the best predictor of physical and mental health (controlling for socio-demographic variables). African men, Bolivian women and women without legal status exhibited the poorest self-rated mental health. Clear differences in health status among natives and immigrants were recorded. The self-selection hypothesis was plausible for physical health of Colombians and Sub-Saharan African men. Acculturation stress could explain poorer mental health in immigrants compared with natives. The association between ethnicity and poor self-reported mental health appears to be partially mediated by discrimination.

Full Text Available Coronary heart disease (CHD incidence has declined significantly in the US, as have levels of major coronary risk factors, including LDL-cholesterol, hypertension and smoking, but whether trends in subclinical atherosclerosis mirror these trends is not known.To describe recent secular trends in subclinical atherosclerosis as measured by serial evaluations of coronary artery calcification (CAC prevalence in a population over 10 years, we measured CAC using computed tomography (CT and CHD risk factors in five serial cross-sectional samples of men and women from four race/ethnic groups, aged 55-84 and without clinical cardiovascular disease, who were members of Multi-Ethnic Study of Atherosclerosis (MESA cohort from 2000 to 2012. Sample sizes ranged from 1062 to 4837. After adjusting for age, gender, and CT scanner, the prevalence of CAC increased across exams among African Americans, whose prevalence of CAC was 52.4% in 2000-02, 50.4% in 2003-04, 60.0% is 2005-06, 57.4% in 2007-08, and 61.3% in 2010-12 (p for trend <0.001. The trend was strongest among African Americans aged 55-64 [prevalence ratio for 2010-12 vs. 2000-02, 1.59 (95% confidence interval 1.06, 2.39; p = 0.005 for trend across exams]. There were no consistent trends in any other ethnic group. Risk factors generally improved in the cohort, and adjustment for risk factors did not change trends in CAC prevalence.There was a significant secular trend towards increased prevalence of CAC over 10 years among African Americans and no change in three other ethnic groups. Trends did not reflect concurrent general improvement in risk factors. The trend towards a higher prevalence of CAC in African Americans suggests that CHD risk in this population is not improving relative to other groups.

Common PCSK1 variants (notably rs6232 and rs6235) have been shown to be associated with obesity in European, Asian and Mexican populations. To determine whether common PCSK1 variants contribute to obesity in American population, we conducted association analyses in 8,359 subjects using two multi-ethnic American studies: the Coronary Artery Risk Development in Young Adults (CARDIA) study and the Multi-Ethnic Study of Atherosclerosis (MESA). By evaluating the contribution of rs6232 and rs6235 in each ethnic group, we found that in European-American subjects from CARDIA, only rs6232 was associated with BMI (P = 0.006) and obesity (P = 0.018) but also increased the obesity incidence during the 20 years of follow-up (HR = 1.53 [1.07-2.19], P = 0.019). Alternatively, in African-American subjects from CARDIA, rs6235 was associated with BMI (P = 0.028) and obesity (P = 0.018). Further, by combining the two case-control ethnic groups from the CARDIA study in a meta-analysis, association between rs6235 and obesity risk remained significant (OR = 1.23 [1.05-1.45], P = 9.5×10(-3)). However, neither rs6232 nor rs6235 was associated with BMI or obesity in the MESA study. Interestingly, rs6232 was associated with BMI (P = 4.2×10(-3)) and obesity (P = 3.4×10(-3)) in the younger European-American group combining samples from the both studies [less than median age (53 years)], but not among the older age group (P = 0.756 and P = 0.935 for BMI and obesity, respectively). By combining all the case-control ethnic groups from CARDIA and MESA in a meta-analysis, we found no significant association for the both variants and obesity risk. Finally, by exploring the full PCSK1 locus, we observed that no variant remained significant after correction for multiple testing. These results indicate that common PCSK1 variants (notably rs6232 and rs6235) contribute modestly to obesity in multi-ethnic American population. Further, these results

To investigate prevalence of urinary incontinence (UI) in a multi-ethnic population of pregnant women, and to analyse for possible associations of the known risk factors for UI in such a population. Population-based cross-sectional study. All pregnant women in three administrative city districts attending the Child Health Clinics. Out of 823 women identified in the [corrected] first trimester, 772 (94%) [corrected] agreed to participate in the study at 28 weeks of gestation. Inclusion criteria were: healthy women at 20 weeks of gestation or less and able to communicate in Norwegian, Arabic, English, Sorani, Somali, Tamil, Turkish, Urdu or Vietnamese. Differences between ethnic groups were tested by simple descriptive statistics. Associations were estimated by logistic regression analysis and presented as crude (cOR) and adjusted (aOR) odds ratios. Prevalence of UI as ascertained using the International Consultation on Incontinence Questionnaire-urinary incontinence-short form. Prevalence rates of UI at 28 weeks of gestation were 26% for women of African origin, 36% for women of Middle Eastern origin, 40% for women of East Asian origin, 43% for women of South Asian origin and 45% for women of European/North American origin. The difference was significant between women of African and European/North American origins (P = 0.011) and between women of African and South Asian origins (P = 0.035). Age (aOR 1.05; 95% CI 1.01-1.09) and parity (aOR 2.34; 95% CI 1.66-3.28) were positively associated with the prevalence of UI in pregnancy. Women of African origin had significantly reduced odds for UI (aOR 0.42; 95% CI 0.20-0.87). East Asian and African women reported the highest perceived impact of UI in pregnancy. A high prevalence of UI was found in a multi-ethnic pregnant population. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

Compared measures of physical activity and dietary habits used in the Health Is Power (HIP) study, and described the associations of physical activity and dietary habits among African American and Hispanic or Latino women, adjusted for weight status. Cross-sectional baseline data were compared for community dwelling, healthy African American (N = 262) and Hispanic or Latina women (N = 148) who participated in HIP. Physical activity was measured using the International Physical Activity Questionnaire (IPAQ) long form, the Check And Line Questionnaire (CALQ) log and accelerometry. Dietary habits were measured using NCI 24-h recall screeners, vegetable and fruit (VF) logs and the NCI Diet History Questionnaire (DHQ). Differences in physical activity and dietary habits were assessed using simultaneous 2 (ethnicity) × 3 (weight status) ANCOVAs adjusted for age and socioeconomic status. Women (M age = 44.4 ± 10.9 years) were obese (M = 34.0 ± 9.7 kg/m(2)), did not meet physical activity guidelines as measured by accelerometry (M = 19.4 ± 19.1 min MVPA/day) and ate few VF (M = 2.8 ± 2.7 servings/day). DHQ variables differed by weight status. IPAQ was associated with CALQ, and CALQ with accelerometry (P habits depending on measure used.

Residential segregation and birth weight among racial and ethnic minorities in the United States.

2009-12-01

Racial and ethnic minorities are often residentially segregated from whites in urban settings, a fact which has important health consequences. Research on the relationship between residential segregation and health outcomes lacks national-level investigation of racial and ethnic minority groups other than African Americans. I use multilevel analyses to examine the associations of residential isolation and clustering with birth weight among Asian, black, and Latino Americans using data from the National Center for Health Statistics' Natality Files and the U.S. Census. Findings indicate that segregation has a negative effect on the likelihood of having a low birth weight baby among Asian Americans, suggesting a possible concentration of social and structural resources in highly-segregated communities. On the contrary, segregation marginally increases the odds of low birth weight among African Americans, but only in the presence of higher poverty rates. Segregation does not affect birth weight among Latino Americans.

Background Beliefs concerning the causes of mental illness may help explain why there are significant disparities in the rates of formal mental health service use among racial/ethnic minority elderly as compared with their Caucasian counterparts. This study applies the Cultural Influences on Mental Health framework to identify the relationship between race/ethnicity and differences in: (1) beliefs on the cause of mental illness; (2) preferences for type of treatment; and (3) provider characteristics. Method Analyses were conducted using baseline data collected from participants who completed the Cultural Attitudes toward Healthcare and Mental Illness Questionnaire, developed for the PRISM-E (Primary Care Research in Substance Abuse and Mental Health for the Elderly) study, a multi-site randomized trial for older adults (65+) with depression, anxiety, or at-risk alcohol consumption. The final sample consisted of 1257 non-Latino Whites, 536 African-Americans, 112 Asian-Americans, and 303 Latinos. Results African-Americans, Asian-Americans, and Latinos had differing beliefs regarding the causes of mental illness when compared to Non-Latino Whites. Race/ethnicity was also associated with determining who makes healthcare decisions, treatment preferences, and preferred characteristics of healthcare providers. Conclusions This study highlights the association between race/ethnicity and health beliefs, treatment preferences, healthcare decisions, and consumers' preferred characteristics of healthcare providers. Accommodating the values and preferences of individuals can be helpful in engaging racial/ethnic minority patients in mental health services. PMID:21992942

Mediation analysis allows the examination of effects of a third variable (mediator/confounder) in the causal pathway between an exposure and an outcome. The general multiple mediation analysis method (MMA), proposed by Yu et al., improves traditional methods (e.g., estimation of natural and controlled direct effects) to enable consideration of multiple mediators/confounders simultaneously and the use of linear and nonlinear predictive models for estimating mediation/confounding effects. Previous studies find that compared with non-Hispanic cancer survivors, Hispanic survivors are more likely to endure anxiety and depression after cancer diagnoses. In this paper, we applied MMA on MY-Health study to identify mediators/confounders and quantify the indirect effect of each identified mediator/confounder in explaining ethnic disparities in anxiety and depression among cancer survivors who enrolled in the study. We considered a number of socio-demographic variables, tumor characteristics, and treatment factors as potential mediators/confounders and found that most of the ethnic differences in anxiety or depression between Hispanic and non-Hispanic white cancer survivors were explained by younger diagnosis age, lower education level, lower proportions of employment, less likely of being born in the USA, less insurance, and less social support among Hispanic patients.

Full Text Available Single-nucleotide polymorphisms (SNPs have been emerging out of the efforts to research human diseases and ethnic disparities. A semantic network is needed for in-depth understanding of the impacts of SNPs, because phenotypes are modulated by complex networks, including biochemical and physiological pathways. We identified ethnicity-specific SNPs by eliminating overlapped SNPs from HapMap samples, and the ethnicity-specific SNPs were mapped to the UCSC RefGene lists. Ethnicity-specific genes were identified as follows: 22 genes in the USA (CEU individuals, 25 genes in the Japanese (JPT individuals, and 332 genes in the African (YRI individuals. To analyze the biologically functional implications for ethnicity-specific SNPs, we focused on constructing a semantic network model. Entities for the network represented by "Gene," "Pathway," "Disease," "Chemical," "Drug," "ClinicalTrials," "SNP," and relationships between entity-entity were obtained through curation. Our semantic modeling for ethnicity-specific SNPs showed interesting results in the three categories, including three diseases ("AIDS-associated nephropathy," "Hypertension," and "Pelvic infection", one drug ("Methylphenidate", and five pathways ("Hemostasis," "Systemic lupus erythematosus," "Prostate cancer," "Hepatitis C virus," and "Rheumatoid arthritis". We found ethnicity-specific genes using the semantic modeling, and the majority of our findings was consistent with the previous studies - that an understanding of genetic variability explained ethnicity-specific disparities.

Inhalant use is of increasing concern as rates appear to be rising among young adolescents and gender differences narrowing. Data from 20,684 Mexican American and White non-Hispanic seventh- and eighth-grade males and females from the Western United States and 15,659 African American and White non-Hispanic seventh- and eighth-grade males and females from states in the southeastern United States collected via in-school surveys from 1996 to 2000 were analyzed using a variety of statistical techniques including multilevel modeling. Questions addressed in the study included: Does inhalant use vary by level of rurality? What effect does the ethnic composition of the community have on inhalant use and does this effect differ by an individual's ethnicity? Do males use more inhalants than females and does the level of use by males and females differ by individual ethnicity, ethnicity of the community, or level of rurality? Do males and females of different ethnicities initiate inhalant use at different ages? Limitations of the study and implications of findings for prevention are discussed and areas of future research are suggested. This study was funded by the National Institute on Drug Abuse.

Ethnic/racial self-labeling represents one's knowledge of and preference for ethnic/racial group membership, which is related to, but distinguishable from, ethnic/racial identity. This study examined the development of ethnic/racial self-labeling over time by including the concept of elaboration among a diverse sample of 297 adolescents (Time 1 mean age 14.75, 67% female, 37.4% Asian or Asian American, 10.4% Black, African American, or West Indian, 23.2% Hispanic or Latinx, 24.2% White, 4.4% other). Growth mixture modeling revealed two distinct patterns-low and high self-labeling elaboration from freshman to sophomore year of high school. Based on logistic regression analyses, the level of self-labeling elaboration was generally low among the adolescents who were foreign-born, reported low levels of ethnic/racial identity exploration, or attended highly diverse schools. We also found a person-by-context interaction where the impact of school diversity varied for foreign-born and native-born adolescents (b = 12.81, SE = 6.30, p self-labeling elaboration among adolescents from diverse backgrounds and their linkage to individual and contextual factors.

Borum, Valerie

2012-01-01

In a qualitative study employing an exploratory design, the researcher explored the perceptions of communication choice and usage among 14 African American hearing parents of deaf and hard of hearing children. Semistructured, in-depth thematic interviews were used with a modified grounded-theory approach in which themes were analyzed and coded. Four thematic challenges and opportunities related to communication choice and usage were found: (a) oral tradition-nommo, (b) sign and oral-diunital, (c) literacy, and (d) racial/ethnic cultural socialization. Afrocentric implications for deaf and hard of hearing children are explored based on research observations pertaining to the significance of the oral tradition in African American culture and the socialization of African American deaf and hard of hearing children in the context of African American hearing families.

Endorsing an Additive Pluricultural Identity Formation for Socio-ethnic Integration in Diasporic Caribbean Societies: An Insightful Culturometric Philosophical Re-examination of Trinidad Ethnic Diversity

Full Text Available This paper looks at Caribbean social spaces and their plasticity within an ontological perspective and how emergent Caribbean identities are arbitrarily constructed, interrogated and restructured at the individual level, artificially fashioned at the collective level and covertly created at the national level. From an ethno-national standpoint, the paper critically explores the process of identity formation from an original ethno-cultural deconstruction segregating ethnic groups by phenotypes to a cultural bricolage of culturally diverse fragments from which emerge the modern pluricultural Caribbean individual, pluricultural ethnicities and the competing cultural allegiances that can threaten to shatter the family unity of the nation state. The paper first explains the additive process of pluricultural identity formation then highlights subtractive multicultural socio-political threats to achieving national unity within a pluricultural Caribbean. This position is discussed here using the results of a survey assessing multicultural allegiances in the predominantly bi-ethnic African/Indian Trinidadian population.

Systemic lupus erythematosus (SLE) is a multi-organ autoimmune disorder that can cause significant morbidity and mortality. A large body of evidence has shown that African-Americans experience the disease more severely than other racial-ethnic groups. Relevant literature for the years 2000 to August 2015 were obtained from systematic searches of PubMed, Scopus, and the EBSCOHost platform that includes MEDLINE, CINAHL, etc. to evaluate research focused on SLE in African-Americans. Thirty-six of the 1502 articles were classified according to their level of evidence. The systematic review of the literature reported a wide range of adverse outcomes in African-American SLE patients and risk factors observed in other mono and multi-ethnic investigations. Studies limited to African-Americans with SLE identified novel methods for more precise ascertainment of risk and observed novel findings that hadn't been previously reported in African-Americans with SLE. Both environmental and genetic studies included in this review have highlighted unique African-American populations in an attempt to isolate risk attributable to African ancestry and observed increased genetic influence on overall disease in this cohort. The review also revealed emerging research in areas of quality of life, race-tailored interventions, and self-management. This review reemphasizes the importance of additional studies to better elucidate the natural history of SLE in African-Americans and optimize therapeutic strategies for those who are identified as being at high risk.

To assess the gender and ethnic differences in arterial compliance in patients with intermittent claudication. A total of 114 patients participated, including 38 Caucasian men, 32 Caucasian women, 16 African American men, and 28 African American women. Patients were assessed on large artery elasticity index (LAEI), small artery elasticity index (SAEI), age, weight, body mass index, ankle-brachial index (ABI), smoking status, and metabolic syndrome components. Group differences were found for LAEI (P = .042), SAEI (P = .019), body mass index (P = .020), prevalence of elevated fasting glucose (P = .001), and prevalence of abdominal obesity (P = .025). Significant covariates for LAEI included age (P = .0002) and elevated triglycerides (P = .0719). LAEI (units = 10 mL x mm Hg) adjusted for age and triglycerides was 39% lower (P = .0005) in African Americans (11.4 +/- .90; mean +/- SE) than in Caucasians (15.8 +/- 0.72), whereas no significant difference (P = .7904) existed between men (13.8 +/- 0.81) and women (13.5 +/- 0.79). Significant covariates for SAEI included age (P = .0001), abdominal obesity (P = .0030), and elevated blood pressure (P = .0067). SAEI (units = 100 mL x mm Hg) adjusted for age, abdominal obesity, and elevated blood pressure was 32% lower (P = .0007) in African-Americans (2.8 +/- 0.3) than in Caucasians 4.1 +/- 0.2), and was 18% lower (P = .0442) in women (3.1 +/- 0.2) than in men (3.8 +/- 0.2). African American patients with intermittent claudication have more impaired macrovascular and microvascular function than Caucasian patients, and women have more impaired microvascular function than men. These ethnic and gender differences in arterial compliance are evident even though ABI was similar among groups, suggesting that arterial compliance provides unique information to quantify vascular impairment in patients with intermittent claudication.

2012-02-01

We investigated racial/ethnic disparities in the diagnosis and treatment of depression among community-dwelling elderly. We performed a secondary analysis of Medicare Current Beneficiary Survey data (n = 33,708) for 2001 through 2005. We estimated logistic regression models to assess the association of race/ethnicity with the probability of being diagnosed and treated for depression with either antidepressant medication or psychotherapy. Depression diagnosis rates were 6.4% for non-Hispanic Whites, 4.2% for African Americans, 7.2% for Hispanics, and 3.8% for others. After we adjusted for a range of covariates including a 2-item depression screener, we found that African Americans were significantly less likely to receive a depression diagnosis from a health care provider (adjusted odds ratio [AOR] = 0.53; 95% confidence interval [CI] = 0.41, 0.69) than were non-Hispanic Whites; those diagnosed were less likely to be treated for depression (AOR = 0.45; 95% CI = 0.30, 0.66). Among elderly Medicare beneficiaries, significant racial/ethnic differences exist in the diagnosis and treatment of depression. Vigorous clinical and public health initiatives are needed to address this persisting disparity in care.

Brown, Danice L; Blackmon, Sha'Kema; Shiflett, Alexandra

2018-06-01

Scholars have posited that childhood socialisation experiences may play a key role in influencing behaviours and attitudes that contribute to the acquisition of HIV. This study examined the links between past ethnic-racial and gender socialisation, sexual assertiveness and the safe sexual practices of African American college women utilising a cluster analytic approach. After identifying separate racial-gender and ethnic-gender socialisation profiles, results indicated that ethnic-gender socialisation cluster profiles were directly associated with sexual assertiveness and safer sex behaviour. Greater levels of ethnic socialisation and low traditional gender role socialisation were found to be associated with greater sexual assertiveness and safer sex behaviour. Further analysis showed that sexual assertiveness mediated the links between the identified ethnic-gender socialisation profiles and safer sex behaviour. Implications for policy and programme development are discussed.

Despite similar prevalence rates across ethnicities, ethnic minorities with obsessive-compulsive disorder (OCD) are under-represented in research and clinical settings. The reasons for this disproportion have been sparsely studied. We explored potential differences in illness perception, help-seeking attitudes, illness knowledge, and causal attributions that could help explain the lower uptake of treatment for OCD amongst ethnic minorities. Two-hundred and ninety-three parents (139 White British, 61 Black African, 46 Black Caribbean, and 47 Indian) were recruited from the general population in South-East London, UK. Using a text vignette methodology, participants completed a survey including questions on illness perception, help-seeking attitudes, OCD knowledge, and causal attributions. The groups did not differ in socio-demographic characteristics and family history of OCD. White British parents perceived that the OCD difficulties would have more negative impact on their children and that treatment would be more helpful, compared to the ethnic minorities; the largest differences were observed between White British and Indian parents. Ethnic minorities were more prone to say that would seek help from their religious communities. Black African parents were more in favor of not seeking help for the described difficulties and, in general, perceived more treatment barriers. White British parents seemed to be better informed about OCD than ethnic minority parents. The results offer some plausible explanations for the large inequalities in access to services amongst ethnic minorities with OCD. Clinicians and policy-makers need to be aware of these socio-cultural factors when designing strategies to encourage help-seeking behaviors in these populations.

2011-12-01

Full Text Available African and Afro-brazilian literature are rising in national educational practice mainly after the publication of the Laws 10.639/03 and 11.645/08 turning mandatory the teaching of African, Afro-arazilian and indigenous history and culture, offering the opportunity to treat racial ethnic relationships in basic education. The article aims to present a reflection based on the results of a weekly pedagogical practice, approaching the education of the racial ethnic relationships through African and Afro-brazilian infantile literature in a classroom of "maternal I" (2 and 3 year old children of a nursery school. Based on a qualitative approach, this research used the method of participant research with the elaboration of a research report. The observation registers in the report allowed us to confirm the resistence to treat racial questions in scholar space. It was also possible to verify that African and Afro-brazilian literatures are substitutes for some literatures that affirm and fortify the myth of racial democracy and are, therefore, obstacles for the laws 10.639/03 and 11.645/08 in schools of basic education.

Family, school, and community factors and relationships to racial-ethnic attitudes and academic achievement.

Smith, Emilie Phillips; Atkins, Jacqueline; Connell, Christian M

2003-09-01

This study examined family, school, and community factors and the relationships to racial-ethnic attitudes and academic achievement among 98 African American fourth-grade children. It has been posited that young people who feel better about their racial-ethnic background have better behavioral and academic outcomes, yet there is a need for more empirical tests of this premise. Psychometric information is reported on measures of parent, teacher, and child racial-ethnic attitudes. Path analysis was used to investigate ecological variables potentially related to children's racial-ethnic attitudes and achievement. Parental education and level of racial-ethnic pride were correlated and both were related to children's achievement though in the final path model, only the path from parental education level was statistically significant. Children whose teachers exhibited higher levels of racial-ethnic trust and perceived fewer barriers due to race and ethnicity evidenced more trust and optimism as well. Children living in communities with higher proportions of college-educated residents also exhibited more positive racial-ethnic attitudes. For children, higher racial-ethnic pride was related to higher achievement measured by grades and standardized test scores, while racial distrust and perception of barriers due to race were related to reduced performance. This study suggests that family, school, and community are all important factors related to children's racial-ethnic attitudes and also to their academic achievement.

2015-05-01

This study examined the utility of a lifetime cumulative adversities and trauma model in predicting the severity of mental health symptoms of depression, anxiety, and posttraumatic stress disorder. We also tested whether ethnicity and gender moderate the effects of this stress exposure construct on mental health using multigroup structural equation modeling. A sample of 500 low-socioeconomic status African American and Latino men and women with histories of adversities and trauma were recruited and assessed with a standard battery of self-report measures of stress and mental health. Multiple-group structural equation models indicated good overall model fit. As hypothesized, experiences of discrimination, childhood family adversities, childhood sexual abuse, other childhood trauma, and chronic stresses all loaded on the latent cumulative burden of adversities and trauma construct (CBAT). The CBAT stress exposure index in turn predicted the mental health status latent variable. Although there were several significant univariate ethnic and gender differences, and ethnic and gender differences were observed on several paths, there were no significant ethnic differences in the final model fit of the data. These findings highlight the deleterious consequences of cumulative stress and trauma for mental health and underscore a need to assess these constructs in selecting appropriate clinical interventions for reducing mental health disparities and improving human health.

2016-10-01

Full Text Available The prevalence of e-cigarette use is increasing, yet few studies have focused on its use in racial/ethnic minority populations. We examined associations between race/ethnicity and e-cigarette use, plans to continue using e-cigarettes, and reasons for use among current/former smokers. Participants (285 in total; 29% non-Hispanic White, 42% African American/Black, and 29% Hispanic were recruited between June and November 2014. Telephone-administered surveys assessed demographics, cigarette smoking, e-cigarette use, plans to continue using, and reasons for use. Analyses of covariance (ANCOVAs and multivariable logistic regressions were conducted. African Americans/Blacks were significantly less likely to report ever-use compared to Whites and Hispanics (50% vs. 71% and 71%, respectively; p < 0.001. However, African American/Black ever users were more likely to report plans to continue using e-cigarettes compared to Whites and Hispanics (72% vs. 53% and 47%, respectively, p = 0.01. African American/Black participants were more likely to use e-cigarettes as a cessation aid compared to both Whites (p = 0.03 and Hispanics (p = 0.48. White participants were more likely to use e-cigarettes to save money compared to Hispanics (p = 0.02. In conclusion, racial/ethnic differences in e-cigarette use, intentions, and reasons for use emerged in our study. African American ever users may be particularly vulnerable to maintaining their use, particularly to try to quit smoking. These findings have implications for cigarette smoking and e-cigarette dual use, continued e-cigarette use, and potentially for smoking-related disparities.

To help eliminate reported racial/ethnic and socioeconomic inequities in oral health care, listening to the perspectives of racial/ethnic minority older adults on their experiences with dental school clinics is needed. The aim of this study was to examine the experiences of African American, Puerto Rican, and Dominican older adults who attend senior centers in upper Manhattan, New York City, regarding the care received at dental school clinics. Focus groups were conducted from 2013 to 2015 with 194 racial/ethnic minority men and women aged 50 years and older living in upper Manhattan. All of the 24 focus group sessions were digitally audiorecorded and transcribed for analysis. Groups conducted in Spanish were transcribed first in Spanish and then translated into English. Analysis of the transcripts was conducted using thematic content analysis. Seven subthemes were manifest in the data related to these adults' positive experiences with dental school clinics: excellent outcomes and dentists, painless and safe treatment, affordable care, honest and reputable, benefits of student training, accepting and helpful, and recommended by family and friends. Negative experiences centered around four subthemes: multiple visits required for treatment, loss of interpersonal communication due to use of technology, inconvenient location, and perceived stigma with Medicaid. This study provided novel evidence of the largely positive experiences with dental schools of racial/ethnic minority senior center attendees. Interventions targeted at the organization and provider level, including organizational motivation, resources, staff attributes, climate, and teamwork plus payment programs and services, insurance and affordability, and provider- and system-level supports, may improve health care processes and patient experiences of care.

Rates of cannabis use differ around the world; in Ontario, the rate of use has been stable since about 2005. Understanding which population groups are at greater risk for problematic cannabis use can help reduce long-term health effects and service expenses. The aim of this study was to explore differences in cannabis use among Canadian adults of different ethnic origins living in Ontario. Data are based on telephone interviews with 11,560 respondents and are derived from multiple cycles (2005-2011) of the Centre for Addiction and Mental Health's (CAMH) Monitor survey, an ongoing cross-sectional survey of adults in Ontario, Canada, aged 18 years and older. Data were analyzed using bivariate cross-tabulations and logistic regression. Problematic cannabis use was determined with a score of 8+ on the ASSIST-CIS to identify moderate/high problematic users. Lifetime, past year and problematic cannabis use (in the past 3 months) occurs among all ethnic groups: Canadian, East Asian, South East Asian, South Asian, Caribbean, African, East European, South European, North European, and Central West European. When compared to the Canadian group the odds of past year cannabis use was significantly lower for East Asians and South Asians, but higher for the Caribbean group. Significantly higher odds of problematic cannabis use were found for Caribbeans and Northern Europeans compared to Canadians. These results of this study provide an important basis for considering the possible impact of the impending legalization of cannabis in Canada among different ethnic groups.

Physical-psychiatric comorbidity: patterns and explanations for ethnic group differences.

Science.gov (United States)

Erving, Christy L

2018-08-01

This paper examines ethnic differences in the co-occurrence of physical and psychiatric health problems (physical-psychiatric comorbidity) for women and men. The following ethnic groups are included: Non-Latino Whites, African Americans, Caribbean Blacks, Spanish Caribbean Blacks, Mexicans, Cubans, Puerto Ricans, Other Latinos, Chinese, Filipinos, Vietnamese, and Other Asian Americans. In addition, the study assesses the extent to which social factors (socioeconomic status, stress exposure, social support) account for ethnic differences in physical-psychiatric comorbidity (PPC). This study uses data from the Collaborative Psychiatric Epidemiology Surveys (CPES) (N = 12,787). Weighted prevalence rates of physical-psychiatric comorbidity (PPC) - the co-occurrence of physical and psychiatric health problems - are included to examine ethnic group differences among women and men. Multinomial logistic regression analysis was used to determine group differences in PPC before and after adjusting for social factors. Puerto Rican men have significantly higher risk of PPC in comparison to Non-Latino White men. Among women, Blacks and Cubans were more likely than Non-Latino Whites to experience PPC as opposed to 'Psychiatric Only' health problems. Social factors account for the Puerto Rican/Non-Latino White difference in comorbid health among men, but have little explanatory power for understanding ethnic differences in comorbidity among women. These findings have implications for medical care and can guide intervention programs in targeting a specific constellation of co-occurring physical and psychiatric health problems for diverse ethnic groups in the United States. As comorbidity rates increase, it is crucial to identify the myriad factors that give rise to ethnic group differences therein.

Wright, Nicole C; Riggs, Gail Kershner; Lisse, Jeffrey R; Chen, Zhao

2008-09-01

The objective of this analysis was to assess risk factors for self-reported osteoarthritis (OA) in an ethnically diverse cohort of women. The participants were postmenopausal women aged 50 to 79 (n=146,494) participating in the clinical trial and observational study of the Women's Health Initiative (WHI). Baseline OA and risk factors were collected from WHI questionnaires. Logistic regression was used to find the association between the risk factors and OA. Risk factor distribution and ethnicity interaction terms were used to assess ethnic differences in OA risk. Forty-four percent of the participants reported OA. Older age (odds ratio (OR)(70-79 vs 50-59)=2.69, 95% confidence interval (CI)=2.60-2.78) and higher body mass index (BMI) (OR(BMI>or=40.0 vs or=30.0) was 57.9% in African Americans, 51.0% in American Indians, 41.9% in Hispanic whites, and 32.9% in non-Hispanic whites. The prevalence of other major OA risk factors was higher in African-American, American-Indian, and Hispanic white women than in non-Hispanic white women. Non-Hispanic white women who were in the extreme obese category (BMI>or=40.0 kg/m(2)) had a 2.80 times (95% CI=2.63, 2.99) greater odds of self-reported OA. The odds were even higher in American-Indian (OR=4.22, 95% CI=1.82, 9.77) and African-American (OR=3.31, 95% CI=2.79, 3.91) women, indicating a significant interactive effect of BMI and ethnicity on odds of OA. In conclusion, OA is a highly prevalent condition in postmenopausal women, and there are differential effects according to ethnicity.

Self-Reported Sleep Bruxism and Nocturnal Gastroesophageal Reflux Disease in Patients with Obstructive Sleep Apnea: Relationship to Gender and Ethnicity§

Science.gov (United States)

Hesselbacher, Sean; Subramanian, Shyam; Rao, Shweta; Casturi, Lata; Surani, Salim

2014-01-01

Study Objectives : Nocturnal bruxism is associated with gastroesophageal reflux disease (GERD), and GERD is strongly associated with obstructive sleep apnea (OSA). Gender and ethnic differences in the prevalence and clinical presentation of these often overlapping sleep disorders have not been well documented. Our aim was to examine the associations between, and the symptoms associated with, nocturnal GERD and sleep bruxism in patients with OSA, and to examine the influence of gender and ethnicity. Methods : A retrospective chart review was performed of patients diagnosed with OSA at an academic sleep center. The patients completed a sleep questionnaire prior to undergoing polysomnography. Patients with confirmed OSA were evaluated based on gender and ethnicity. Associations were determined between sleep bruxism and nocturnal GERD, and daytime sleepiness, insomnia, restless legs symptoms, and markers of OSA severity in each group. Results : In these patients with OSA, the prevalence of nocturnal GERD (35%) and sleep bruxism (26%) were higher than the general population. Sleep bruxism was more common in Caucasians than in African Americans or Hispanics; there was no gender difference. Nocturnal GERD was similar among all gender and ethnic groups. Bruxism was associated with nocturnal GERD in females, restless legs symptoms in all subjects and in males, sleepiness in African Americans, and insomnia in Hispanics. Nocturnal GERD was associated with sleepiness in males and African Americans, insomnia in females, and restless legs symptoms in females and in Caucasians. Conclusion : Patients with OSA commonly have comorbid sleep bruxism and nocturnal GERD, which may require separate treatment. Providers should be aware of differences in clinical presentation among different ethnic and gender groups. PMID:25352924

Cardiovascular disease, diabetes and established risk factors among populations of sub-Saharan African descent in Europe: a literature review

2009-08-01

Full Text Available Abstract Background Most European countries are ethnically and culturally diverse. Globally, cardiovascular disease (CVD is the leading cause of death. The major risk factors for CVD have been well established. This picture holds true for all regions of the world and in different ethnic groups. However, the prevalence of CVD and related risk factors vary among ethnic groups. Methods This article provides a review of current understanding of the epidemiology of vascular disease, principally coronary heart disease (CHD, stroke and related risk factors among populations of Sub-Sahara African descent (henceforth, African descent in comparison with the European populations in Europe. Results Compared with European populations, populations of African descent have an increased risk of stroke, whereas CHD is less common. They also have higher rates of hypertension and diabetes than European populations. Obesity is highly prevalent, but smoking rate is lower among African descent women. Older people of African descent have more favourable lipid profile and dietary habits than their European counterparts. Alcohol consumption is less common among populations of African descent. The rate of physical activity differs between European countries. Dutch African-Suriname men and women are less physically active than the White-Dutch whereas British African women are more physically active than women in the general population. Literature on psychosocial stress shows inconsistent results. Conclusion Hypertension and diabetes are highly prevalent among African populations, which may explain their high rate of stroke in Europe. The relatively low rate of CHD may be explained by the low rates of other risk factors including a more favourable lipid profile and the low prevalence of smoking. The risk factors are changing, and on the whole, getting worse especially among African women. Cohort studies and clinical trials are therefore needed among these groups to

Do birds of a feather flock together? The variable bases for African American, Asian American, and European American adolescents' selection of similar friends.

Science.gov (United States)

Hamm, J V

2000-03-01

Variability in adolescent-friend similarity is documented in a diverse sample of African American, Asian American, and European American adolescents. Similarity was greatest for substance use, modest for academic orientations, and low for ethnic identity. Compared with Asian American and European American adolescents, African American adolescents chose friends who were less similar with respect to academic orientation or substance use but more similar with respect to ethnic identity. For all three ethnic groups, personal endorsement of the dimension in question and selection of cross-ethnic-group friends heightened similarity. Similarity was a relative rather than an absolute selection criterion: Adolescents did not choose friends with identical orientations. These findings call for a comprehensive theory of friendship selection sensitive to diversity in adolescents' experiences. Implications for peer influence and self-development are discussed.

The Loneliness Questionnaire: Establishing Measurement Invariance Across Ethnic Groups.

Ritchwood, Tiarney D; Ebesutani, Chad K; Chin, Eu Gene; Young, John

2017-09-01

A state of loneliness describes an individual's perception of having dissatisfying social connections to others. Though it is notable across the life span, it may have particularly deleterious effects in childhood and adolescence, leading to increased risk of emotional impairment. The current study evaluates a widely used test of loneliness, the Loneliness Questionnaire, for measurement invariance across ethnic groups in a large, representative sample of youth in the 2nd to 12th grades ( N = 12,344; 41% African American) in Mississippi. Analyses were conducted using multigroup confirmatory factor analysis following a published, sequential method to examine invariance in form, factor loadings, and item intercepts. Overall, our results indicated that the instrument was invariant across ethnicities, suggesting that youth with equivalent manifest scores can be discerned as having comparable levels of latent loneliness. The loneliness scores also corresponded significantly with depression and anxiety scores for most subsamples, with one exception. These findings are discussed in the context of previous results comparing levels of loneliness across ethnicities. Additionally, the broader context of the need to expand invariance studies in instrumentation work is highlighted.

Sims, Mario; Sims, Tammy L; Bruce, Marino A

2008-07-01

This study examines the extent to which the relationship between area socioeconomic position (SEP) and low birth weight (LBW) varies by race and ethnicity. A cross-sectional, secondary data analysis was performed with 1992-1994 Vital Statistics and 1990 U.S. Census data for selected metropolitan areas. Low birth weight (rates were calculated for non-Hispanic Black, Latino, and non-Hispanic White live singleton births. Concentrated poverty was defined as poor persons living in neighborhoods with 40% or more poverty in metropolitan areas. The results showed that the relationship between concentrated poverty and LBW varied by race and ethnicity. Concentrated poverty was significant for Latinos, even when controlling for maternal health and MSA-level factors. By contrast, maternal health characteristics, such as pre-term birth, teen birth and tobacco use, explained much of the variance in African-American and White LBW These findings extend the discussion about race, class, and health disparities to include Latinos and shows how the relationship between SEP and LBW can vary within an ethnic group.

Evaluating cohort and intervention effects on black adolescents' ethnic-racial identity: a cognitive-cultural approach.

Science.gov (United States)

Whaley, Arthur L; McQueen, John P

2010-11-01

The importance of ethnic-racial socialization and ethnic-racial identity as protective factors in the psychological and social adjustment of Black youth is well established in the literature. Whaley (2003) developed a cognitive-cultural model of identity to explicate the process by which ethnic-racial socialization impacts ethnic-racial identity and subsequent social and behavioral outcomes among adolescents of African descent. The present study tests the cognitive-cultural model of identity utilizing pilot data from a modified Africentric intervention program. Both explicit and implicit aspects of ethnic-racial identity were evaluated between two cohorts: one group in 2003, which represented historical controls, and another group in 2008 which received the intervention and has pre-test and post-test data. We hypothesized that the evaluation of underlying implicit or schematic processes would be more sensitive to changes in ethnic-racial identity resulting from cohort and intervention effects. Our results confirmed this hypothesis. Implications of applying mainstream behavioral science research paradigms to issues of special concern to the Black community are discussed.

There is no data available on the ABO/Rh(D) frequencies in the Mauritanian population. We retrospectively analysed records of a 5-year database that contained ABO/Rh phenotype and ethnic origin of 10 116 volunteers giving blood at the national blood transfusion centre to derive the frequencies of ABO/Rh(D) groups in the Mauritanian population. The two race categories in the country and their sub-ethnic groups: the Moors (whites and black) and the black Africans (Pulhars, Soninkes and Wolof) were included in this study. Globally, group O had the highest frequency (49.10%) followed by A (28.28%), B (18.56%) and AB (4.05%). This order more common in North African populations was found in four of the five ethnic groups composing our population. Allele frequencies were, respectively, 70.20%, 17.74% and 12.04% giving the same order of O > A > B. We observed no significant variation in these frequencies between the different ethnic groups. Rhesus study showed that with a percentage of 94.23% Rh(D) positive is by far the most prevalent, while Rh(D) negative is present only in 5.77% of the total population. This frequency distribution supports the mixed-race composition of the Mauritanian population. © 2011 Blackwell Publishing Ltd.

Research is needed to confirm that public health recommendations for home/family food environments are equally relevant for diverse populations. This study examined ethnic/racial differences in the home/family environments of adolescents and associations with dietary intake and weight status. The sample included 2374 ethnically/racially diverse adolescents and their parents enrolled in coordinated studies, EAT 2010 (Eating and Activity in Teens) and Project F-EAT (Families and Eating and Activity in Teens), in the Minneapolis/St. Paul metropolitan area. Adolescents and parents completed surveys and adolescents completed anthropometric measurements in 2009-2010. Nearly all home/family environment variables (n=7 of 8 examined) were found to vary significantly across the ethnic/racial groups. Several of the home/family food environment variables were significantly associated with one or more adolescent outcome in expected directions. For example, parental modeling of healthy food choices was inversely associated with BMI z-score (p=0.03) and positively associated with fruit/vegetable consumption (peating was associated with lower intake of sugar-sweetened beverages only among youth representing the White, African American, Asian, and mixed/other ethnic/racial groups and was unrelated to intake among East African, Hispanic, and Native American youth. Food and nutrition professionals along with other providers of health programs and services for adolescents should encourage ethnically/racially diverse parents to follow existing recommendations to promote healthy eating such as modeling nutrient-dense food choices, but also recognize the need for cultural sensitivity in providing such guidance.

Targeted marketing of high-calorie foods and beverages to ethnic minority populations, relative to more healthful foods, may contribute to ethnic disparities in obesity and other diet-related chronic conditions. We conducted a systematic review of studies published in June 1992 through 2006 (n = 20) that permitted comparison of food and beverage marketing to African Americans versus Whites and others. Eight studies reported on product promotions, 11 on retail food outlet locations, and 3 on food prices. Although the evidence base has limitations, studies indicated that African Americans are consistently exposed to food promotion and distribution patterns with relatively greater potential adverse health effects than are Whites. The limited evidence on price disparities was inconclusive.

Kidwell, David A; Smith, Frederick P; Shepherd, Arica R

2015-12-01

The question of why different races appear more susceptible to hair contamination by external drugs remains controversial. This research studied susceptibility of head hair to external cocaine and methamphetamine when hair products have been applied. Three different chemical classes of ethnic hair products were applied to Caucasian, Asian, and African hair. Some products increased the methamphetamine and cocaine concentrations in all hair types. A unique finding of this research is that certain ethnic hair products can replace moisture as a diffusion medium, thereby increasing the susceptibility to contamination over 100-fold compared to petroleum-based products.

This article reports on the association between ethnic identity and condom use among Black African men in the rural areas of the Eastern Cape Province, South Africa. Individual face-to-face structured interviews were conducted by trained community research assistants among 1,656 men who had undergone traditional initiation and male circumcision. Logistic regression analyses were used to explore the association between two components of ethnic identity (cultural affiliation and cultural alienation) and condom use. Overall, 49.2 % of the participants reported using condoms consistently and, of these users, 66.4 % used them correctly. Logistic regression adjusting for age, employment status, education level, and nation of origin showed that participants who expressed high as opposed to low cultural affiliation were significantly more likely to use condoms consistently and correctly when having sex, especially if they reported to have more than one sexual partner. Cultural alienation was negatively related with consistent condom use, whereas its association with correct use was unclear. The findings of this study suggest that positively emphasizing the ethnic identity of African black men may promote condom use.

Full Text Available BACKGROUND: To examine ethnic differences in cardiometabolic risk profile in early age, and explore whether such differences can be explained by differences in body mass index (BMI or waist circumference (WC. METHOD: Anthropometric measurements, blood pressure and (in a subsample fasting blood were collected during a health check of 2,509 children aged 5-6 years. Four ethnic groups were distinguished: Dutch (n=2,008; blood n=1,300, African descent (n=199; blood n=105, Turkish (n=108; blood n=57 and Moroccan (n=194; blood n=94. Ethnic differences in diastolic and systolic blood pressure (DBP/SBP, fasting glucose, low-density lipoprotein (LDL, high-density lipoprotein (HDL and triglyceride levels were determined and the explanatory role of BMI and WC was examined with regression analysis. RESULTS: After adjustment for confounders, African descent children showed higher DBP (β2.22 mmHg; 95%CI:1.09-3.36 and HDL levels (β:0.09 mmol/l; 95%CI:0.03-0.16 compared to Dutch children (reference group. Turkish children showed higher SBP (β:1.89 mmHg; 95%CI:0.25-3.54, DBP (β:2.62 mmHg; 95%CI:1.11-4.13, glucose (β:0.12 mmol/L; 95%CI:0.00-0.25 and triglyceride levels (β:0.13 mmol/L; 95%CI:0.02-0.25. Higher BMI values were found in all non-Dutch groups (differences ranged from 0.53-1.03 kg/m(2 and higher WC in Turkish (β:1.68 cm; 95%CI:0.99-2.38 and Moroccan (β:1.65 cm; 95%CI:1.11-2.19 children. BMI and WC partly explained the higher SBP/DBP and triglyceride levels in Turkish children. CONCLUSION: Ethnic differences in cardiometabolic profile exist early in life and are partly explained by differences in BMI and WC. African children showed favourable HDL levels and Turkish children the most unfavourable overall profile, whereas their Moroccan peers have less increased cardiometabolic risk in spite of their high BMI and WC.

Large-scale representative surveys of 8th-, 10th-, and 12th-grade students in the United States show high self-esteem scores for all groups. African-American students score highest, Whites score slightly higher than Hispanics, and Asian Americans score lowest. Males score slightly higher than females. Multivariate controls for grades and college plans actually heighten these race/ethnic/gender differences. A truncated scoring method, designed to counter race/ethnic differences in extreme response style, reduced but did not eliminate the subgroup differences. Age differences in self-esteem are modest, with 12th graders reporting the highest scores. The findings are highly consistent across 18 annual surveys from 1991 through 2008, and self-esteem scores show little overall change during that period.

Obesity is a global concern, affecting both developed and developing countries. Although there are large variations in obesity and breast cancer rates worldwide and across racial/ethnic groups, most studies evaluating the impact of obesity on breast cancer risk and survival have been conducted in non-Hispanic white women in the United States or Europe. Given the known racial/ethnic differences in tumor hormone receptor subtype distribution, obesity prevalence, and risk factor profiles, we reviewed published data for women of African, Hispanic, and Asian ancestry in the United States and their countries of origin. Although the data are limited, current evidence suggests a stronger adverse effect of obesity on breast cancer risk and survival in women of Asian ancestry. For African Americans and Hispanics, the strength of the associations appears to be more comparable to that of non-Hispanic whites, particularly when accounting for subtype and menopausal status. Central obesity seems to have a stronger impact in African-American women than general adiposity as measured by body mass index. International data from countries undergoing economic transition offer a unique opportunity to evaluate the impact of rapid weight gain on breast cancer. Such studies should take into account genetic ancestry, which may help elucidate differences in associations between ethnically admixed populations. Overall, additional large studies that use a variety of adiposity measures are needed, because the current evidence is based on few studies, most with limited statistical power. Future investigations of obesity biomarkers will be useful to understand possible racial/ethnic biological differences underlying the complex association between obesity and breast cancer development and progression. © 2015 American Society for Nutrition.

Recently, determination of skeletal age, defined as the assessment of bone age, has rapidly become an important task between forensic experts and radiologists. The Greulich-Pyle (GP) atlas is one of the most frequently used methods for the assessment of skeletal age around the world. After presentation of the GP approach for the estimation of the bone age, much research has been conducted to examine the usability of this method in various geographic or ethnic categories. This study investigates on a small-scale and compares the reliability of the GP atlas for assessment of the bone age for four ethnic groups - Asian, African/American, Caucasian and Hispanic - for a different range of ages. Plain radiographs of 184 left hands and wrists for males from the healthy sample between 1 to 18 years of age for four ethnic groups were taken. The skeletal age (SA) was estimated by a radiologist using the GP atlas. The blind method was utilized. The mean (SA) results were compared with mean chronological ages (CA) for the separate ethnic groups. SPSS was used to conduct the analysis and the paired t-test was applied to show the difference between the mean CA and mean SA achieved from the GP atlas. The results from the GP atlas were compared to the CA of the samples. In Asian subjects the mean difference was 0.873 years. The GP atlas showed delayed bone age at 2-7 ages (from 0.2 to 2.3 year) and then advanced bone age for age 8. In the African/American subjects the difference between CA and SA was statistically significant (P-value = 0.048). The mean difference in the Caucasian and Hispanic subjects reflects no considerable distinction with a standard deviation (SD) of 0.3088 and 0.3766, respectively, (P-value >0.05 for both groups). According to the present study, it is concluded that although the GP atlas is reliable for Caucasian and Hispanic ethnic groups it is not applicable for other ethnic groups for different ranges of age, especially in the sample of the male African

Full Text Available Cardiorespiratory fitness is an important health indicator in young people. The aim of this study was to investigate the effects of age, gender, body adiposity, and ethnicity on cardiorespiratory fitness in a sample of Portuguese adolescents. The sample consisted of 266 adolescents aged 12-18 years [112 boys (80 Caucasians and 32 African-Portuguese, AP and 154 girls (109 Caucasians and 45 AP]. Percent body fat was estimated with a hand-to-hand bioelectrical impedance device (BF300, OMROM. Cardiorespiratory fitness was assessed by a shuttle run test (Fitnessgram battery. Multiple regression models were used for statistical analysis. The results showed that girls presented lower maximal oxygen consumption and higher percent body fat than boys. Cardiorespiratory fitness was lower in Caucasian than in AP girls. Multiple regression analysis showed that percent body fat, age and the interaction of age with being Caucasian and age with female gender were significant determinants that were negatively associated with cardiorespiratory fitness. The results suggest that maximal oxygen consumption is lower in adolescents with higher adiposity and in older adolescents. The findings highlight the importance of promoting physical fitness in schools across ages, especially in older adolescents, adjusting for determinant factors such as gender and ethnicity

The objective of this analysis was to assess risk factors for self-reported osteoarthritis (OA) in an ethnically diverse cohort of women. The participants were postmenopausal women aged 50 to 79 (n=146,494) participating in the clinical trial and observational study of the Women’s Health Initiative (WHI). Baseline OA and risk factors were collected from WHI questionnaires. Logistic regression was used to find the association between the risk factors and OA. Risk factor distribution and ethnicity interaction terms were used to assess ethnic differences in OA risk. Forty-four percent of the participants reported OA. Older age (odds ratio (OR)70–79 vs 50–59=2.69, 95% confidence interval (CI)=2.60–2.78) and higher body mass index (BMI) (ORBMI≥40.0 vs <24.9=2.80, 95% CI=2.63–2.99) were found to be the strongest risk factors associated with self-reported OA. The prevalence of obesity (BMI≥30.0) was 57.9% in African Americans, 51.0% in American Indians, 41.9% in Hispanic whites, and 32.9% in non-Hispanic whites. The prevalence of other major OA risk factors was higher in African-American, American-Indian, and Hispanic white women than in non-Hispanic white women. Non-Hispanic white women who were in the extreme obese category (BMI≥40.0λkg/m2) had a 2.80 times (95% CI=2.63, 2.99) greater odds of self-reported OA. The odds were even higher in American-Indian (OR=4.22, 95% CI=1.82, 9.77) and African-American (OR=3.31, 95% CI=2.79, 3.91) women, indicating a significant interactive effect of BMI and ethnicity on odds of OA. In conclusion, OA is a highly prevalent condition in postmenopausal women, and there are differential effects according to ethnicity. PMID:18662212
