[source] Differentiation of Caucasians and Chinese at Bone Mass Candidate Genes: Implication for Ethnic Difference of Bone MassANNALS OF HUMAN GENETICS, Issue 3 2003V. Dvornyk Summary Bone mineral density (BMD) is an important risk factor for osteoporosis and has strong genetic determination. While average BMD differs among major ethnic groups, several important candidate genes have been shown to underlie BMD variation within populations of the same ethnicity. To investigate whether important candidate genes may contribute to ethnic differences in BMD, we studied the degree of genetic differentiation among several important candidate genes between two major ethnic groups: Caucasians and Chinese. The genetic variability of these two populations (1131 randomly selected individuals) was studied at six restriction sites exhibiting polymorphisms of five important candidate genes for BMD: the BsaHI polymorphism of the calcium-sensing receptor (CASR) gene, the SacI polymorphism of the ,2HS-glycoprotein (AHSG) gene, the PvuII and XbaI polymorphisms of the estrogen receptor , (ESR1) gene, the ApaI polymorphism of the vitamin D receptor (VDR) gene, and the BstBI polymorphism of the parathyroid hormone (PTH) gene. The two ethnic groups showed significant allelic and genotypic differentiation of all the polymorphisms studied. The mean FST was 0.103, which significantly differed from zero (P < 0.01). The Chinese population had lower mean heterozygosity (0.331) than the Caucasian one (0.444); the CASR - BsaHI and PTH - BstBI polymorphisms contributed most significantly to this difference. Analysis of the intra- and inter-population variability suggests that various types of natural selection may affect the observed patterns of variation at some loci. If some of the candidate genes we studied indeed underlie variation in BMD, their population differentiation revealed here between ethnic groups may contribute to understanding ethnic difference in BMD. [source] Ethnic Differences in Birth Outcomes in England,FISCAL STUDIES, Issue 1 2006Lorraine Dearden Abstract This paper uses the Millennium Cohort Study to look at ethnic differences in birth outcomes for a cohort of English children born in 2000 and 2001. There is an increasingly large literature showing that longer gestation and higher birthweight are positively associated with cognitive and non-cognitive outcomes later in life, so understanding sources of ethnic differences in these outcomes and identifying factors that may influence birth outcomes has a lot of potential policy interest. This paper shows that even after controlling for background characteristics in a number of ways, there still remain unexplained differences in both gestation and birthweight outcomes across broad ethnic groups. It also suggests, however, that there may be potential policy levers that could be used to narrow this ethnic gap in birth outcomes, such as reducing the proportion of underweight Asian mothers and overweight Black mothers and increasing ethnic minority attendance at antenatal classes. [source] Gender and Ethnic Differences in Marital Assimilation in the Early Twentieth Century,INTERNATIONAL MIGRATION REVIEW, Issue 3 2005Sharon Sassler Historical research on intermarriage has overlooked how distinctive patterns of ethnic settlement shape partner choice and assumed that the mate selection process operated the same way for men and women. This study utilizes a sample of youn married adults drawn from the 1910 Census IPUMS to examine 1) whether ethnic variation in partner choice was shaped by differences in group concentration and distribution and 2) if factors shaping outmarriage were gendered. About one fifth of young married Americans had spouses of a different ethnic background in 1910, though there was considerable ethnic variation in outmarriage propensities. Barriers to intermarriage fell at different rates, depending upon ethnic grou, sex, and region of settlement; they were weakest for first-and seconl eneration English men. Structural factors such as group size operatef differently for men and women; while larger group representation increased men's odds of outmarriage to both native stock and other white ethnic wives, women from the ethnic groups with the largest presence were significantly more likely to wed fellow ethnics than the native stock. Ultimately, even if they resided in the same location, the marriage market operated in different ways for ethnic women and men in search of mates. [source] Ethnic Differences in Singapore's Dementia Prevalence: The Stroke, Parkinson's Disease, Epilepsy, and Dementia in Singapore StudyJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 11 2008Suresh Sahadevan MBBS OBJECTIVES: To study the prevalence of dementia in Singapore among Chinese, Malays, and Indians. DESIGN: A two-phase, cross-sectional study of randomly selected population from central Singapore with disproportionate race stratification. SETTING: Community-based study. Subjects screened to have cognitive impairment at phase 1 in their homes were evaluated clinically for dementia at phase 2 in nearby community centers. PARTICIPANTS: Fourteen thousand eight hundred seventeen subjects aged 50 and older (67% participation rate). MEASUREMENTS: The locally validated Abbreviated Mental Test was used to screen for cognitive impairment at phase 1. Dementia was diagnosed at phase 2 as per Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria. Possible Alzheimer's disease (AD) and possible vascular dementia (VD) were diagnosed along the National Institute of Neurological and Communicative Disorders,Alzheimer's Disease and Related Disorders Association and National Institute of Neurological Disorders and Stroke,Association Internationale pour la Recherche et l'Enseignement en Neuroscienes criteria, respectively. RESULTS: The overall age- and race-standardized dementia prevalence was 1.26% (95% confidence interval (CI)=1.10,1.45). Prevalence (in 5-year age bands) was 0.08% (50,54), 0.08% (55,59), 0.44% (60,64), 1.16% (65,69), 1.84% (70,74), 3.26% (75,79), 8.35% (80,84), and 16.42% (,85). From age 50 to 69, 65% of dementia cases were VD; at older ages, 60% were AD. Logistic regression (adjusted for age, sex, education) showed that Malays had twice the risk for AD as Chinese, and Indians had more than twice the risk for AD and VD than Chinese. CONCLUSION: Singapore's dementia prevalence, primarily influenced by its Chinese majority, is lower than seen in the West. The striking interethnic differences suggest a need for a dementia incidence study and further investigation of underlying genetic and cultural differences between the three ethnic groups in relation to dementia risk. [source] Racial and Ethnic Differences in Experiencing Parents' Marital Disruption During Late AdolescenceJOURNAL OF MARRIAGE AND FAMILY, Issue 3 2007Yongmin Sun Using panel data from 9,252 adolescents in the National Education Longitudinal Study, this study finds that among children who experience parents' marital disruption during late adolescence, European, Asian, and African American adolescents exhibit wider and greater maladjustment both before and after the disruption than their Hispanic American counterparts. This finding lends general support to the hypothesis of prevalence of disadvantages, although it is less consistent with the hypothesis of prevalence of divorce. Moreover, whereas Asian American adolescents in predisrupted families are more vulnerable to a shortage of family social resources, their African American peers are affected more by a shortage of financial/human resources. Finally, postdisruption effects on non-Hispanic American adolescents are either completely or partially attributable to predisruption factors. [source] Racial and Ethnic Differences in the Timing of First Marriage and Smoking CessationJOURNAL OF MARRIAGE AND FAMILY, Issue 3 2007Margaret Weden Using data from the National Longitudinal Survey of Youth 1979 (N = 4,050), we consider the relationship between the timing of family formation and positive changes in health behavior. Theories that predict both positive and negative associations are tested. The findings suggest that both mechanisms operate and that the direction of the association depends on the respondent's race or ethnicity. Whites who marry early are less likely to quit smoking, whereas Whites who marry on time and Blacks and Hispanics who marry at all ages are more likely to quit. The analysis refines the understanding of how family formation shapes changes in health behaviors differentially across the life course, and it underscores the difference in this process for individuals from different racial and ethnic backgrounds. [source] First Politics, Then Culture: Accounting for Ethnic Differences in Demographic Behavior in KenyaPOPULATION AND DEVELOPMENT REVIEW, Issue 3 2001Alexander A. Weinreb Ethnic differences in demographic behavior tend to be disguised behind analytically opaque labels like "district" or "region," or else subjected to simplistic cultural explanations. Drawing on new political economy, sociological theory and the political science literature on sub-Saharan Africa, this article proposes an alternative explanatory model and tests it empirically with reference to Kenya. Access to political power and, through power, access to a state's resources,including resources devoted to clinics, schools, labor opportunities, and other determinants of demographic behavior,are advanced as the key factors underlying ethnic differences. District-level estimates of "political capital" are introduced and merged with two waves of Demographic and Health Survey data. The effects on models of contraceptive use are explored. Results confirm that measures of political capital explain residual ethnic differences in use, providing strong support for a political approach to the analysis of demographic behavior. [source] Racial and Ethnic Differences in Mortality in Children Awaiting Heart Transplant in the United StatesAMERICAN JOURNAL OF TRANSPLANTATION, Issue 12 2009T. P. Singh Racial differences in outcomes are well known in children after heart transplant (HT) but not in children awaiting HT. We assessed racial and ethnic differences in wait-list mortality in children <18 years old listed for primary HT in the United States during 1999,2006 using multivariable Cox models. Of 3299 listed children, 58% were listed as white, 20% as black, 16% as Hispanic, 3% as Asian and 3% were defined as ,Other'. Mortality on the wait-list was 14%, 19%, 21%, 17% and 27% for white, black, Hispanic, Asian and Other children, respectively. Black (hazard ratio [HR] 1.6, 95% confidence interval [CI] 1.3, 1.9), Hispanic (HR 1.5, CI 1.2, 1.9), Asian (HR, 2.0, CI 1.3, 3.3) and Other children (HR 2.3, CI 1.5, 3.4) were all at higher risk of wait-list death compared to white children after controlling for age, listing status, cardiac diagnosis, hemodyamic support, renal function and blood group. After adjusting additionally for medical insurance and area household income, the risk remained higher for all minorities. We conclude that minority children listed for HT have significantly higher wait-list mortality compared to white children. Socioeconomic variables appear to explain a small fraction of this increased risk. [source] Racial and Ethnic Differences in Emergency Care for Acute Exacerbation of Chronic Obstructive Pulmonary DiseaseACADEMIC EMERGENCY MEDICINE, Issue 2 2009Chu-Lin Tsai MD ScD Abstract Objectives:, The objective was to investigate racial and ethnic differences in emergency care for patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Methods:, The authors performed a prospective multicenter cohort study involving 24 emergency departments (EDs) in 15 U.S. states. Using a standard protocol, consecutive ED patients with AECOPD were interviewed, their charts reviewed, and 2-week telephone follow-ups were completed. Results:, Among 330 patients, 218 (66%) were white, 84 (25%) were African American, and 28 (8%) were Hispanic. A quarter of the 24 EDs cared for 59% of all minority patients. Compared with white patients, African American and Hispanic patients were more likely to be uninsured or with Medicaid (19, 49, and 52%, respectively; p < 0.001), were less likely to have a primary care provider (93, 81, and 82%, respectively; p = 0.005), and had more frequent ED visits in the past year (medians = 1, 2, and 3, respectively; p = 0.002). In the unadjusted analyses, minority patients were less likely to receive diagnostic procedures, more likely to receive systemic corticosteroids in the ED, less likely to be admitted, and more likely to have a relapse. After adjustment for patient and ED characteristics, these many racial and ethnic differences in quality of care were nearly completely eliminated. Conclusions:, Despite pronounced racial and ethnic differences in stable COPD, all racial and ethnic groups received comparable quality of emergency care for AECOPD and had similar short-term outcomes. [source] Ethnicity affects the diagnostic validity of alpha-fetoprotein in hepatocellular carcinomaASIA-PACIFIC JOURNAL OF CLINICAL ONCOLOGY, Issue 2-3 2005Amal GAD Abstract Introduction: Hepatocellular carcinoma (HCC) is the fourth most common cancer worldwide with a high morbidity and mortality. Alpha-fetoprotein (AFP) is considered the main tumor marker for HCC diagnosis, but the variation in its diagnostic validity among studies justifies further investigation of the underlying contributing factors. Ethnic difference could be one of the factors that has not been well studied. We aimed at investigating the ethnic difference in AFP validity between Egyptian (representing Arabic North African) and Japanese (representing Asian) for HCC diagnosis. Methods: Four cohorts with chronic liver diseases (CLD) were studied: 171 Egyptian (65 HCC/106 non-HCC), and 173 Japanese (45 HCC/128 non-HCC). Laboratory tests including serum AFP, protein-induced vitamin K deficiency or absence (PIVKA-II), alanine aminotransferase (ALT), total bilirubin, platelet count, HBsAg, anti-HCV, and HCV core antigen were conducted using standard commercially available assays. Results: A significantly higher sensitivity of AFP in Egyptian in comparison with Japanese for HCC diagnosis (99 vs 67%, P < 0.001) was observed using an AFP cut-off point of 10 ng/mL, with a comparable specificity, (75,vs, 82%), While, a, sensitivity, of, 98, versus, 56%,,P < 0.001, and, a, specificity, of, 83, versus, 89% was found for AFP cut-off point of 20 ng/mL, respectively. The area under the receiver operating characteristic curve (ROC) was found to be 0.98 (95%CI = 0.969,0.997) for Egyptian and 0.77 (95%CI = 0.686,0.864) for Japanese. The highest sensitivity for the former group occurred at AFP = 20.5 ng/mL and at AFP = 10.2 ng/mL for the latter. Univariate analysis showed no effect for age, sex, underlying liver disease, cirrhosis, Child's class or tumor characteristics (size, pathological grade) on AFP sensitivity, while race significantly contributed to the higher sensitivity among Egyptians in comparison with the Japanese. Using ROC analysis, the AFP cut-off point for HCC detection in each subgroup of patients with and without each of the risk factors of interest was determined and the subgroups were again subclassified according to AFP positivity (< or , the decided cut-off point for each group). Logistic regression analysis of those factors combined showed that Egyptian ethnicity with an AFP level >20.5 ng/mL (P = 0.007), older age (>50 years) with an AFP level >26 ng/mL (P = 0.010), and cirrhosis with an AFP level >10.5 ng/mL (P = 0.014) were the independent risk factors for HCC. Conclusion: There is an ethnic variation in AFP validity between Egyptian and Japanese patients with a significantly lower sensitivity in the latter. Alpha-fetoprotein should not be the only marker used for screening HCC among Asian Japanese and younger age groups (<50 years) with CLD. In addition, an AFP cut-off point of 20 ng/mL is recommended when screening patients of Asian origin for HCC. [source] Ethnic differences in plantar pressures in diabetic patients with peripheral neuropathyDIABETIC MEDICINE, Issue 4 2008M. P. Solano Abstract Aims To compare plantar foot pressures between Caucasian and Hispanic diabetic patients with peripheral neuropathy (PN) without a history of foot ulceration and between Caucasian and Hispanic non-diabetic individuals. Methods Forty-four Hispanic diabetic patients with PN (HDPN), 35 Caucasian diabetic patients with PN (CDPN), 41 non-diabetic Hispanic subjects and 33 non-diabetic Caucasian subjects participated. Total and regional peak plantar pressures (PPs) and pressure time integrals (PTIs) were assessed using the EMED-SF-4 plantar pressure system. Results Hispanic diabetic patients with PN had significantly lower peak PP than Caucasian diabetic patients with PN in the entire foot (552.4 ± 227.9 vs. 810.1 ± 274.6 kPa; P < 0.001), forefoot (464.1 ± 222.6 vs. 699.6 ± 323.1 kPa; P < 0.001), hindfoot (296.3.4 + 101.8 vs. 398.1 + 178.3 kPa; P < 0.01) and at the fifth metatarsal head (MTH5; 204.3 ± 143.2 vs. 388.2 ± 273.9 kPa; P < 0.001). The PTI in the entire foot, forefoot and MTH5 were also lower in HDPN than in CDPN. The ethnic differences between the diabetic groups with PN for the entire foot, forefoot and MTH5 remained significant after adjusting for the effect of age, gender, weight and duration of diabetes. There were no significant differences in peak PP and PTI among non-diabetic individuals, except for a lower peak PP at the MTH5 in Hispanic compared with Caucasian subjects. Conclusions Despite a well-known higher incidence of foot complications in diabetic Hispanic subjects, dynamic plantar pressures are lower in Hispanic diabetic patients with PN when compared with their Caucasian counterparts, suggesting that differences in other risk factors exist between these two ethnic groups. [source] Ethnic differences in the timely diagnosis of children with Type 1 diabetes mellitus in the Netherlands: clinical presentation at onsetDIABETIC MEDICINE, Issue 3 2007J. J. N. Van Laar Abstract Aims Little is known about ethnic differences in the timely diagnosis of Type 1 diabetes mellitus (Type 1 DM). This study aimed to assess ethnic inequalities in the timely diagnosis of Type 1 DM, as indicated by a more adverse clinical condition at onset. In addition, we assessed whether these differences could be explained by differences in socio-economic status. Methods From a national register, we selected 3128 children aged < 15 years with newly diagnosed Type 1 DM. Ethnic differences in serum glucose, blood pH, bicarbonate, presence of ketonuria, level of consciousness, hydration status, and diabetic ketoacidosis were assessed by logistic regression. A measure of socio-economic status based on postal codes was used as an explanatory variable. Results The risk of adverse clinical presentation was 1.5,2 times higher in non-Western immigrants than Dutch children, while Western immigrant children did not differ from Dutch children. Blood pH, bicarbonate level, and level of consciousness were lower in Turkish and Antillean children in particular. The adverse socio-economic position of immigrant children contributed very little to these differences in clinical presentation. Conclusions Non-Western children were likely to be sicker at first presentation of Type 1 DM, and thus diagnosis may have been delayed. These disparities were not accounted for by differences in socio-economic status. Possible explanations may be difficulties in recognition of symptoms, failure of GPs to take symptom reporting seriously and lack of awareness of the fact that Type 1 DM occurs more often in certain ethnic groups. [source] Ethnic differences and determinants of diabetes and central obesity among South Asians of PakistanDIABETIC MEDICINE, Issue 7 2004T. H. Jafar Abstract Aims To study the within ethnic subgroup variations in diabetes and central obesity among South Asians. Methods Data from 9442 individuals age , 15 years from the National Health Survey of Pakistan (NHSP) (1990,1994) were analysed. Diabetes was defined as non-fasting blood glucose , 7.8 mmol/l, or known history of diabetes. Central obesity was measured at the waist circumference. Distinct ethnic subgroups Muhajir, Punjabi, Sindhi, Pashtun, and Baluchi were defined by mother tongue. Results The age-standardized prevalence of diabetes varied among ethnic subgroups (P = 0.002), being highest among the Muhajirs (men 5.7%, women 7.9%), then Punjabis (men 4.6%, women 7.2%), Sindhis (men 5.1%, women 4.8%), Pashtuns (men 3.0%, women 3.8%), and lowest among the Baluchis (men 2.9%, women 2.6%). While diabetes was more prevalent in urban vs. rural dwellers [odds ratio (OR) 1.50, 95% confidence interval (CI) 1.24, 1.82], this difference was no longer significant after adjusting for central obesity (OR 1.15, 95% CI 0.95, 1.42). However, the ethnic differences persisted after adjusting for major sociodemographic risk factors (unadjusted OR for Pashtun vs. Punjabi 0.59, 95% CI 0.42, 0.84, adjusted OR 0.54, 95% CI 0.37, 0.78). Ethnic variation was also observed in central obesity, which varied with gender, and did not necessarily track with ethnic differences in diabetes. Conclusions Unmeasured environmental or genetic factors account for ethnic variations in diabetes and central obesity, and deserve further study. [source] Ethnic differences in drinking outcomes following a brief alcohol intervention in the trauma care settingADDICTION, Issue 1 2010Craig A. Field ABSTRACT Background Evidence suggests that brief interventions in the trauma care setting reduce drinking, subsequent injury and driving under the influence (DUI) arrest. However, evidence on the effectiveness of these interventions in ethnic minority groups is lacking. The current study evaluates the efficacy of brief intervention among whites, blacks and Hispanics in the United States. Methods We conducted a two-group parallel randomized trial comparing brief motivational intervention (BMI) and treatment as usual with assessment (TAU+) to evaluate treatment differences in drinking patterns by ethnicity. Patients were recruited from a level 1 urban trauma center over a 2-year period. The study included 1493 trauma patients, including 668 whites, 288 blacks and 537 Hispanics. Hierarchical linear modeling was used to evaluate ethnic differences in drinking outcomes including volume per week, maximum amount consumed in 1 day, percentage days abstinent and percentage days heavy drinking at 6- and 12-month follow-up. Analyses controlled for age, gender, employment status, marital status, prior alcohol treatment, type of injury and injury severity. Special emphasis was given to potential ethnic differences by testing the interaction between ethnicity and BMI. Results At 6- and 12-month follow-up, BMI significantly reduced maximum amount consumed in 1 day (P < 0.001; P < 0.001, respectively) and percentage days heavy drinking (P < 0.05; P < 0.05, respectively) among Hispanics. Hispanics in the BMI group also reduced average volume per week at 12-month follow-up (,2 = 6.8, df = 1, P < 0.01). In addition, Hispanics in TAU+ reduced maximum amount consumed at 6- and 12-month follow-up (P < 0.001; P < 0.001) and volume per week at 12-month follow-up (P < 0.001). Whites and blacks in both BMI and TAU+ reduced volume per week and percentage days heavy drinking at 12-month follow-up (P < 0.001; P < 0.01, respectively) and decreased maximum amount at 6- (P < 0.001) and 12-month follow-up (P < 0.001). All three ethnic groups In both BMI and TAU+ reduced volume per week at 6-month follow-up (P < 0.001) and percentage days abstinent at 6- (P < 0.001) and 12-month follow-up (P < 0.001). Conclusions All three ethnic groups evidenced reductions in drinking at 6- and 12-month follow-up independent of treatment assignment. Among Hispanics, BMI reduced alcohol intake significantly as measured by average volume per week, percentage days heavy drinking and maximum amount consumed in 1 day. [source] Characteristics of Household Addresses That Repeatedly Contact 911 to Report Intimate Partner ViolenceACADEMIC EMERGENCY MEDICINE, Issue 6 2004Debra Houry MD Abstract Objectives: To determine whether households that generate several 911 calls differ in important ways from those that make a single call and to determine whether households that generate repeat 911 calls for intimate partner violence (IPV) experience more severe violence than those that do not. Methods: All cases of police-documented IPV were reviewed and linked with their respective 911 calls. Each incident report was reviewed to determine the relationship between the offender and victim, demographic characteristics of the offender and victim, weapon and substance involvement, prior incidents of IPV, and violence severity. Results: Of the 1,505 IPV addresses identified during the 12-month study interval, 1,010 (67.1%) placed more than one phone call to report IPV. Sixty-nine percent of African American victims, 50.6% of white victims, and 36.8% of Hispanic victims were repeat callers (p < 0.001). There were no differences between addresses that generated repeat calls versus single calls with respect to offender alcohol or drug involvement, presence of children, victim age, or offender age. Sixty-seven percent of households with severe violence and 66.9% of households with minor violence generated repeat 911 calls (p = 0.98). Conclusions: Ethnic differences in 911 use for IPV exist between African Americans, whites, and Hispanics. However, unknown societal, economic, or cultural issues could have influenced this finding. Households that repeatedly contacted 911 during the study interval to report IPV were not more likely to experience severe violence than those that placed a single 911 call. [source] An Empirical Examination of Religion and Conflict in the Middle East, 1950,1992FOREIGN POLICY ANALYSIS, Issue 1 2006BRIAN LAI This article examines the influence of religion on conflict in the Middle East. It develops a more refined approach to studying the effects of religion by examining intra-Islamic differences as well as the effects of domestic politics and religion on conflict. It tests these hypotheses on all Middle Eastern dyads from 1950 to 1992, including appropriate control variables. This article finds that religious identity does matter but only when its relationship with conflict is more clearly specified. Religious differences between the leaders of states influence the likelihood of militarized disputes, but not religious differences between the populations of two states. Ethnic differences and power politics also influence the likelihood of an militarized interstate dispute. [source] Helicobacter pylori, Ethnicity, and the Gastroesophageal Reflux Disease Spectrum: A Study from the EastHELICOBACTER, Issue 2 2007Shanmugarajah Rajendra Abstract Background:, Ethnic differences in gastroesophageal reflux disease (GERD) and its complications as well as racial variations in the prevalence of Helicobacter pylori infection are well documented. Nevertheless, the association between reflux disease, H. pylori, and race has not been adequately explored. Aims:, We estimated the strength of the association between H. pylori, ethnicity, and the gastroesophageal reflux disease (GERD) spectrum, including Barrett's esophagus, in Asian patients presenting for endoscopy in a tertiary referral center. Methods:, Prospectively, we studied 188 consecutive patients with GERD, short- and long-segment Barrett's esophagus, and controls. All patients underwent gastroscopy with gastric biopsies to assess H. pylori, gastritis, and atrophy. CagA status and H. pylori infection were determined by immunoblot assay. Results:, The overall prevalence of H. pylori infection was 52.1% (of which 77.6% were cagA+) and was lowest in the long-segment Barrett's esophagus group (36.7%) (p = .048). When Barrett's esophagus was present, the length of abnormality was 44.8% shorter in the presence of H. pylori (p = .015). Indians had the highest prevalence of H. pylori (75%) and Malays the lowest (19.6%) (p < .001). In Indians, increased prevalence of H. pylori and cagA -positive strains was associated with reduced severity of GERD (p < .004 and p < .001, respectively), a trend not apparent in the other races. Corpus atrophy, which was almost exclusively associated with H. pylori, was highest in Indians as compared to the other races (p = .013). Conclusions:, Presence of H. pylori was associated with a reduced severity of GERD spectrum disease in Asians, especially Indians. H. pylori infection may protect against complicated reflux disease via induction of corpus atrophy. [source] Hereditary breast and ovarian cancer in Asia: genetic epidemiology of BRCA1 and BRCA2,HUMAN MUTATION, Issue 6 2002Alexander Liede Abstract Ethnic differences in cancer incidence and mortality result from differences in genetic and epidemiologic risk factors. Mutations in BRCA1 and BRCA2 account for a small proportion of all breast cancer cases, but for a much higher proportion of cases with a strong family history of breast or ovarian cancer. Germline mutations in BRCA1 and BRCA2 have been identified in individuals of many races and ethnic groups and the frequency of mutations varies between these groups. Some of the differences in cancer risk between populations may be the result of founder mutations in these genes. The cost and time required for mutation analysis are reduced considerably when founder mutations are identified for a specific ethnic group. The BRCA2 999del5 mutation in Iceland and three BRCA mutations in Ashkenazi Jews are well characterized. However, considerably less is known about the contribution of mutations in the BRCA1 and BRCA2 genes outside of European groups. Studies conducted on the Asian populations described here have expanded our current knowledge of genetic susceptibility and its contribution to breast and ovarian cancer rates in Asian populations.

(2010) Ethnic differences in exercise and leisure time physical activity among midlife women. Journal of Advanced Nursing66(4), 814,827. Abstract Title.,Ethnic differences in exercise and leisure time physical activity among midlife women. Aim., This paper is a report of a study of factors associated with ethnic differences in exercise and leisure time physical activity levels among midlife women. Background., Most studies on physical activity have focused mostly on identifying correlates of physical activity. However, ,ethnicity/race' as a factor affecting exercise and leisure time physical activity has rarely been considered. Method., This study was a secondary analysis of data from a larger Internet study on menopausal symptoms of midlife women from four ethnic groups in the United States of America. A total of 441 women aged 40,60 years were recruited through the Internet from 31 January 2005 to 31 December 2007. The data were analysed using descriptive statistics, chi-square analysis, analysis of variance and multiple regressions. Findings., Non-Hispanic White people had a statistically significantly higher level of leisure time physical activity than Asian Americans and Hispanics. African Americans reported the lowest level of exercise. Body mass index was inversely associated with exercise among African Americans. Menopausal symptoms were positively associated with exercise among non-Hispanic White people and African Americans. Employment and number of children had a statistically significantly inverse association with exercise among Asian Americans. Conclusion., Correlates of exercise are ethnic-specific. The dual role situation of working outside and inside their homes is an important factor in explaining the lower participation of exercise among Asian Americans. Health factors influence exercise participation in non-Hispanic White people, African Americans and Hispanics. Nurses should take into account ethnic diversities when designing physical activity interventions for women. [source] Osteoporosis and Fracture Risk in Women of Different Ethnic GroupsJOURNAL OF BONE AND MINERAL RESEARCH, Issue 2 2005Elizabeth Barrett-Connor MD Abstract Osteoporosis and 1-year fracture risk were studied in 197,848 postmenopausal American women from five ethnic groups. Weight explained differences in BMD, except among blacks, who had the highest BMD. One SD decrease in BMD predicted a 50% increased fracture risk in each group. Despite similar relative risks, absolute fracture rates differed. Introduction: Most information about osteoporosis comes from studies of white women. This study describes the frequency of osteoporosis and the association between BMD and fracture in women from five ethnic groups. Materials and Methods: This study was made up of a cohort of 197,848 community-dwelling postmenopausal women (7784 blacks, 1912 Asians, 6973 Hispanics, and 1708 Native Americans) from the United States, without known osteoporosis or a recent BMD test. Heel, forearm, or finger BMD was measured, and risk factor information was obtained; 82% were followed for 1 year for new fractures. BMD and fracture rates were compared, adjusting for differences in covariates. Results: By age 80, more than one-fifth of women in each ethnic group had peripheral BMD T scores <,2.5. Black women had the highest BMD; Asian women had the lowest. Only the BMD differences for blacks were not explained by differences in weight. After 1 year, 2414 new fractures of the spine, hip, forearm, wrist, or rib were reported. BMD at each site predicted fractures equally well within each ethnic group. After adjusting for BMD, weight, and other covariates, white and Hispanic women had the highest risk for fracture (relative risk ,RR' 1.0 ,referent group' and 0.95, 95% CI, 0.76, 1.20, respectively), followed by Native Americans (RR, 0.87; 95% CI, 0.57, 1.32), blacks (RR, 0.52; 95% CI, 0.38, 0.70), and Asian Americans (RR, 0.32; 95% CI, 0.15, 0.66). In age- and weight-adjusted models, each SD decrease in peripheral BMD predicted a 1.54 times increased risk of fracture in each ethnic group (95% CI, 1.48-1.61). Excluding wrist fractures, the most common fracture, did not materially change associations. Conclusions: Ethnic differences in BMD are strongly influenced by body weight; fracture risk is strongly influenced by BMD in each group. Ethnic differences in absolute fracture risk remain, which may warrant ethnic-specific clinical recommendations. [source] Ethnic differences in use value and use patterns of baobab (Adansonia digitata L.) in northern BeninAFRICAN JOURNAL OF ECOLOGY, Issue 3 2009E. De Caluwé Abstract The aim of this study was to combine qualitative and quantitative tools to evidence ethnic differences in use value and use patterns of baobab for the rural populations of northern Benin. The study was carried out in the municipalities of Boukoumbé and Karimama, focusing on Ottamari and Dendi ethnic groups, respectively, who have good knowledge on baobab uses. Ethnobotanical data were gathered through semi-structured individual interviews and processed by quantitative (multiple use curve, use value and fidelity level) and qualitative (flow chart) analytical and ethnobotanical methods. Leaves, fruit pulp and seeds of baobab were shown to be well-known for several food uses and were often the main ingredient in sauces, pastes, porridges and beverages. Medicinal uses were especially well-known for the bark, which was also used for making ropes. In both communities, a total of 38 different uses were mentioned for baobab products. There were significantly more uses known by the Ottamari than by the Dendi, with use values of 8 and 5, respectively. There were no differences detected in knowledge between sexes and age classes. As a result of its nutritional and high potential market value, preservation of ethnobotanical knowledge on baobab and exchange between communities is critical. Résumé Le but de cette étude était de combiner des outils qualitatifs et quantitatifs pour mettre en évidence des différences ethniques dans la valeur d'utilisation et dans les schémas d'utilisation du baobab chez les populations rurales du nord du Bénin. Cette étude fut réalisée dans les municipalités de Boukoumbé et de Karimama, spécifiquement chez les groupes ethniques Ottamari et Dendi, respectivement, qui ont une bonne connaissance des utilisations du baobab. Des données ethnobotaniques furent récoltées grâce à des interviews individuelles semi-structurées et elles furent traitées par des méthodes analytiques et ethnobotaniques quantitatives (courbe d'utilisation multiple, valeur d'utilisation et degré de fidélité) et qualitatives (graphique d'évolution). Les feuilles, la pulpe de fruits et les semences de baobab se sont avérées être bien connues pour plusieurs utilisations alimentaires et elles étaient souvent les ingrédients principaux dans des sauces, des pâtes, des bouillies et des boissons. Des utilisations médicinales étaient particulièrement bien connues pour l'écorce qui servait aussi pour fabriquer des cordes. Dans les deux communautés, un total de 38 utilisations différentes ont été mentionnées pour des produits du baobab. Il y avait significativement plus d'utilisations connues chez les Ottamari que chez les Dendi, avec des valeurs d'utilisation de 8 et de 5, respectivement. On n'a décelé aucune différence de connaissances en fonction de l'âge ni du sexe. Suite à sa valeur nutritionnelle et à sa haute valeur commerciale potentielle, la préservation des connaissances ethnobotaniques sur le baobab et des échanges entre communautés est critique. [source] Comparison of genetic polymorphisms of the NAT2 gene between Korean and four other ethnic groupsJOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 6 2009T. S. Kang MS Summary Background and objective:,N -acetyltransferase 2 (NAT2) is responsible for the acetylation of numerous drugs and in the transformation of aromatic and heterocyclinc amines into carcinogenic intermediates. Polymorphism of NAT2 may contribute to interindividual variability in such acetylation. The aim of this study was to determine the allele frequencies of polymorphisms of the NAT2 gene, analyse linkage disequilibrium (LD) block and haplotypes in Koreans and compare them with those of other ethnic groups. Methods:, We analysed genetic polymorphisms in all functional promoter and exons of the NAT2 gene by direct sequencing of genomic DNA from 192 healthy Korean subjects. The LD and haplotype blocks of these subjects were constructed from genotype data using an expectation,maximization algorithm. We compared these allele frequencies, LD block and haplotype structure with those of other ethnic groups registered on the International HapMap database. Results and discussion:, We identified 33 polymorphisms including six novel single nucleotide polymorphisms, ,10778T>C, ,10777A>G, ,10351A>G, ,10199C>T and ,10104G>T in promoter and 578C>T in exon2 (T193M) in the Korean subjects tested. All allele frequencies reported in the Koreans were similar to those of Asians except for one allele (rs4345600, ,9306A>G), whereas African and European groups had different frequencies in exon2. The haplotype structure and LD block among the five groups also revealed significant differences. Conclusion:, Ethnic differences in the NAT2 genotype frequencies may be one of the important factors explaining variability in cancer incidence and drug toxicity. Our observations could be useful in assessing the susceptibility of different populations to cancer and contribute to better predictions of the pharmacokinetics and pharmacodynamics of drugs that are metabolized by NAT2, in different populations. [source] Multicultural Crisis Communication: Towards a Social Constructionist PerspectiveJOURNAL OF CONTINGENCIES AND CRISIS MANAGEMENT, Issue 4 2006Jesper Falkheimer Crisis communication is a field dominated by case studies and is lacking of systematic knowledge and theoretical framework analysis. Functionalist and objectivist perspectives have dominated the field even though there are exceptions. This may be one reason why multicultural approaches to crisis communication, increasingly relevant in contemporary society, are very few and undeveloped. The aim in the article is to give a critical analysis of research that has been done on crisis communication as well as intercultural public relations and develop a different theoretical framework. We propose the use of ethnicity, focusing collective cultural identity as dynamic, relational and situational in crisis theory and practice. Ethnic differences seem to escalate during crises. Media use and access are also discussed. A Swedish survey shows, among other things, that people with a foreign background read mainstream newspapers more seldom than average Swedes, but that the access to Internet and mobile phones is very high. Based on a social constructionist epistemology, the article ends with four proposals for future research and practice in multicultural crisis communication: (1) audience-orientation , focusing sense-making, (2) a proactive and interactive approach , focusing dialogue, (3) a community-focused approach , focusing a long-range pre-crisis perspective and, (4) an ethnicity-approach towards intercultural communication. [source] Ethnic differences in anemia among patients with diabetes mellitus: The Diabetes Study of Northern California (DISTANCE),AMERICAN JOURNAL OF HEMATOLOGY, Issue 1 2010Ameena T. Ahmed To examine ethnic differences in hemoglobin testing practices and to test the hypothesis that ethnicity is an independent predictor of anemia among patients with diabetes mellitus. We conducted a panel study to assess the rate of hemoglobin testing during 1999,2001 and the period prevalence and incidence of anemia among 79,985 adults with diabetes mellitus receiving care within Kaiser Permanente of Northern California. Anemia was defined as hemoglobin <13.0 g/dL in men or < 12.0 g/dL in women. Overall, 82.1% of the cohort was tested for anemia at least once during the 3-year study period. Mixed ethnicity patients were most likely to be tested, followed by whites, blacks, Latinos, and Asians (P < 0.0001). Fifteen percent of the cohort had prevalent anemia at baseline, and an additional 22% of those tested developed anemia during the study period. Anemia was more prevalent among blacks and mixed ethnicity persons compared with other racial/ethnic groups. Anemia was also more prevalent among those ,70 years of age or with estimated glomerular filtration rate <60 ml/min/1.73 m2. In multivariable models, blacks had higher and Asians had lower odds of prevalent anemia and hazard ratios of incident anemia compared with whites. Within a large, diverse cohort with diabetes, ethnicity was predictive of anemia, even after adjustment for age, level of kidney function, and other potential confounders. Blacks with diabetes are at increased risk of anemia relative to whites. These differences may account for some of the observed ethnic disparities in diabetes complications. Am. J.

[source] First Politics, Then Culture: Accounting for Ethnic Differences in Demographic Behavior in KenyaPOPULATION AND DEVELOPMENT REVIEW, Issue 3 2001Alexander A. Weinreb Ethnic differences in demographic behavior tend to be disguised behind analytically opaque labels like "district" or "region," or else subjected to simplistic cultural explanations. Drawing on new political economy, sociological theory and the political science literature on sub-Saharan Africa, this article proposes an alternative explanatory model and tests it empirically with reference to Kenya. Access to political power and, through power, access to a state's resources,including resources devoted to clinics, schools, labor opportunities, and other determinants of demographic behavior,are advanced as the key factors underlying ethnic differences. District-level estimates of "political capital" are introduced and merged with two waves of Demographic and Health Survey data. The effects on models of contraceptive use are explored. Results confirm that measures of political capital explain residual ethnic differences in use, providing strong support for a political approach to the analysis of demographic behavior. [source] Ethnic differences in spatial mobility: the impact of family tiesPOPULATION, SPACE AND PLACE (PREVIOUSLY:-INT JOURNAL OF POPULATION GEOGRAPHY), Issue 4 2009Aslan Zorlu Abstract In the last three decades, the population of Amsterdam has been ,coloured' due to immigration flows from abroad and a low outflow rate among these immigrants and their descendants. The question is to what extent differences in the spatial mobility behaviours of migrants and natives are generated by neighbourhood characteristics , including the level of ethnic segregation and family ties? This article examines spatial mobility processes in the Amsterdam population using administrative individual data covering the entire population of the city. The analysis shows that Caribbean (Surinamese and Antillean) migrants have a higher probability of moving to the suburbs while Moroccans and Turks tend to rearrange themselves within the city. The estimates reveal that neighbourhood ,quality' has only a modest impact on the probability of moving, while family ties significantly hamper the out-mobility of all individuals. The impact of family ties is the largest for Turkish and Moroccan migrants. Copyright © 2009 John Wiley & Sons, Ltd. [source] Ethnic differences in participation in prenatal screening for Down syndrome: A register-based studyPRENATAL DIAGNOSIS, Issue 10 2010Mirjam P. Fransen Abstract Objective To assess ethnic differences in participation in prenatal screening for Down syndrome in the Netherlands. Methods Participation in prenatal screening was assessed for the period 1 January 2009 to 1 July 2009 in a defined postal code area in the southwest of the Netherlands. Data on ethnic origin, socio-economic background and age of participants in prenatal screening were obtained from the Medical Diagnostic Centre and the Department of Clinical Genetics. Population data were obtained from Statistics Netherlands. Logistic regression models were used to assess ethnic differences in participation, adjusted for socio-economic and age differences. Results The overall participation in prenatal screening was 3865 out of 15 093 (26%). Participation was 28% among Dutch women, 15% among those from Turkish ethnic origin, 8% among those from North-African origin, 15% among those from Aruban/Antillean origin and 26% among women from Surinamese origin. Conclusions Compared to Dutch women, those from Turkish, North-African, Aruban/Antillean and other non-Western ethnic origin were less likely to participate in screening. It was unexpected that women from Surinamese origin equally participated. It should be further investigated to what extent participation and non-participation in these various ethnic groups was based on informed decision-making. Copyright © 2010 John Wiley & Sons, Ltd. [source] Ethnic differences in quality of life among early breast and prostate cancer survivorsPSYCHO-ONCOLOGY, Issue 2 2002Carolyn Cook Gotay This study assessed quality of life (QOL) in recently diagnosed breast and prostate cancer patients of European American and Asian Pacific Islanders (specifically, individuals of Filipino, Japanese, and Native Hawaiian ancestry) to investigate whether QOL varied according to ethnicity and the relative importance of ethnicity as a predictor of QOL. Participants were identified through consecutive registrations on the Hawaii Tumor Registry, based on a diagnosis of breast or prostate cancer 4,6 months previously. QOL was measured by the QLQ-C30, a standardized questionnaire widely used in cancer patient populations. Two hundred and twenty-seven individuals participated (101 prostate and 126 breast cancer patients). QOL was similar across ethnic groups in most areas of QOL. However, differences were found in several areas, all in the direction of Filipino patients reporting worse outcomes. Hierarchical stepwise regressions supported the importance of ethnicity, controlling for clinical and demographic predictors. We conclude that additional research is needed to understand the relationship between ethnicity and QOL in cancer survivors. Copyright © 2002 John Wiley & Sons, Ltd.
