Evidence from epidemiological studies shows a link between food insecurity and diet intake or quality. However, the moderating effect of race in this relation has not yet been studied. Food insecurity (USDA Food Security Module) and diet quality (Healthy Eating Index-2010; HEI) were measured in 1741 participants from the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study. Data were collected from 2004 to 2009 and analyzed in 2014. Multivariable regression assessed the interaction of race and food insecurity on HEI scores, adjusting for age, sex, poverty status, single parent status, drug, alcohol and cigarette use, and comorbid diseases. The interaction of food insecurity and race was significantly associated with diet quality (p = 0.001). In the absence of food insecurity, HEI scores were similar across race. However, with each food insecurity item endorsed, HEI scores were substantially lower for Whites compared to Blacks. An ad hoc analysis revealed that Blacks were more likely than Whites to participate in SNAP (p < 0.05). Further, race stratified analyses revealed that Blacks participating in SNAP showed diminished associations of food insecurity with diet quality. Study findings provide the first evidence that the influence of food insecurity on diet quality may be potentiated for Whites, but not Blacks. Additionally, results show that Blacks are more likely to participate in SNAP and show attendant buffering of the effects of food insecurity on diet quality. These findings may have important implications for understanding how food insecurity affects diet quality differentially by race.

Lifetime health disparity between African-American and white females begins with lower birthweight and higher rates of childhood overweight. In adolescence, African-American girls experience earlier menarche. Understanding the origins of these health disparities is a national priority. There is growing literature suggesting that the life course health development model is a useful framework for studying disparities. The purpose of this study was to quantify the influence of explanatory factors from key developmental stages on the age of menarche and to determine how much of the overall race difference in age of menarche they could explain. The factors were maternal age of menarche, birthweight, poverty during early childhood (age 0 through 5 years), and child BMI z-scores at 6 years. The sample, drawn from the US National Longitudinal Surveys of Youth Child-Mother file, consisted of 2337 girls born between 1978 and 1998. Mean age of menarche in months was 144 for African-American girls and 150 for whites. An instrumental variable approach was used to estimate a causal effect of child BMI z-score on age of menarche. The instrumental variables were pre-pregnancy BMI, high gestational weight gain and smoking during pregnancy. We found strong effects of maternal age of menarche, birthweight, and child BMI z-score (-5.23, 95% CI [-7.35,-3.12]) for both African-Americans and whites. Age of menarche declined with increases in exposure to poverty during early childhood for whites. There was no effect of poverty for African-Americans. We used Oaxaca decomposition techniques to determine how much of the overall race difference in age of menarche was attributable to race differences in observable factors and how much was due to race dependent responses. The African-American/white difference in childhood BMI explained about 18% of the overall difference in age of menarche and birthweight differences explained another 11%.

Previous studies suggested that the racial differences in U.S. suicide rates are decreasing, particularly for African Americans, but the cause behind the temporal variations has yet to be determined. This study aims to investigate the long-term trends in suicide mortality in the U.S. between 1983 and 2012 and to examine age-, period-, and cohort-specific effects by gender and race. Suicide mortality data were collected from the Web-based Injury Statistics Query and Reporting System (WISQARS) and analyzed with the Joinpoint regression and age-period-cohort (APC) analysis. We found that although age-standardized rate of suicide in white males, white females, black males, and black females all changed at different degrees, the overall situation almost has not changed since these changes offset each other. By APC analysis, while the age effect on suicide demonstrate an obvious difference between white males and females (with the peak at 75 to 79 for white males and 45 to 54 for white females), young black people are predominantly susceptible to suicide (risk peaks in early 20s for black males and late 20s for black females). Cohort effects all showed a descending trend, except that in white males and females which showed an obvious increase peaked in around cohort 1960. There was a similar period effect trend between different genders in the same race group, but between the races, differences were found in the period before 1990 and after 2000. We confirmed that the distinction in age-specific suicide rate patterns does exist by gender and by race after controlling for period and cohort effects, which suggested that minorities' age patterns of suicide may have been masked up by the white people in the whole population. The differences of period effects and cohort effects between white and black Americans were likely to be mainly explained by the difference in race susceptibility to economic depression.

BACKGROUND: The changing racial and ethnic diversity of the U.S. population along with delayed childbearing suggest that shifts in the demographic composition of gravidas are likely. It is unclear whether trends in the proportion of births to parous women in the United States have changed over the decades by race and ethnicity, reflecting parallel changes in population demographics. METHODS: Singleton deliveries > or = 20 weeks of gestation in the United States from 1989 through 2000 were analyzed using data from the "Natality data files" assembled by the National Center for Health Statistics (NCHS). We classified maternal age into three categories; younger mothers (aged < 30 years), mature mothers (30-39 years) and older mothers (> or = 40 years) and maternal race/ethnicity into three groups: blacks (non-Hispanic), Hispanics and whites (non-Hispanic). We computed birth rates by period of delivery across the entire population and repeated the analysis stratified by age and maternal race. Chi-squared statistics for linear trend were utilized to assess linear trend across three four-year phases: 1989-1992, 1993-1996 and 1997-2000. In estimating the association between race/ethnicity and parity status, the direct method of standardization was employed to adjust for maternal age. RESULTS: Over the study period, the total number of births to blacks and whites diminished consistently (p for trend < 0.001), whereas among Hispanics a progressive increase in the total number of deliveries was evident (p for trend < 0.001). Black and white women experienced a reduction in total deliveries equivalent to 10% and 9.3%, respectively, while Hispanic women showed a substantial increment in total births (25%). Regardless of race or ethnicity, birth rate was associated with increase in maternal age in a dose-effect fashion among the high (5-9 previous live births), very high (10-14 previous live births) and extremely high (> or = 15 previous live births) parity groups (p for trend

Age-Specific Incidence of Breast Cancer Subtypes: Understanding the Black–White Crossover

PubMed Central

2012-01-01

Background Breast cancer incidence is higher among black women than white women before age 40 years, but higher among white women than black women after age 40 years (black–white crossover). We used newly available population-based data to examine whether the age-specific incidences of breast cancer subtypes vary by race and ethnicity. Methods We classified 91908 invasive breast cancers diagnosed in California between January 1, 2006, and December 31, 2009, by subtype based on tumor expression of estrogen receptor (ER) and progesterone receptor (PR)—together referred to as hormone receptor (HR)—and human epidermal growth factor receptor 2 (HER2). Breast cancer subtypes were classified as ER or PR positive and HER2 negative (HR+/HER2−), ER or PR positive and HER2 positive (HR+/HER2+), ER and PR negative and HER2 positive (HR−/HER2+), and ER, PR, and HER2 negative (triple-negative). We calculated and compared age-specific incidence rates, incidence rate ratios, and 95% confidence intervals by subtype and race (black, white, Hispanic, and Asian). All P values are two-sided. Results We did not observe an age-related black–white crossover in incidence for any molecular subtype of breast cancer. Compared with white women, black women had statistically significantly higher rates of triple-negative breast cancer at all ages but statistically significantly lower rates of HR+/HER2− breast cancers after age 35 years (all P < .05). The age-specific incidence of HR+/HER2+ and HR−/HER2+ subtypes did not vary markedly between white and black women. Conclusions The black–white crossover in breast cancer incidence occurs only when all breast cancer subtypes are combined and relates largely to higher rates of triple-negative breast cancers and lower rates of HR+/HER2− breast cancers in black vs white women.

Objective To determine the distribution of screening PSA values in older men and how different PSA thresholds affect the proportion of white, black, and Latino men who would have an abnormal screening result across advancing age groups. Methods We used linked national VA and Medicare data to determine the value of the first screening PSA test (ng/mL) of 327,284 men age 65+ who underwent PSA screening in the VA healthcare system in 2003. We calculated the proportion of men with an abnormal PSA result based on age, race, and common PSA thresholds. Results Among men age 65+, 8.4% had a PSA >4.0ng/mL. The percentage of men with a PSA >4.0ng/mL increased with age and was highest in black men (13.8%) versus white (8.0%) or Latino men (10.0%) (P<0.001). Combining age and race, the probability of having a PSA >4.0ng/mL ranged from 5.1% of Latino men age 65–69 to 27.4% of black men age 85+. Raising the PSA threshold from >4.0ng/mL to >10.0ng/mL, reclassified the greatest percentage of black men age 85+ (18.3% absolute change) and the lowest percentage of Latino men age 65–69 (4.8% absolute change) as being under the biopsy threshold (P<0.001). Conclusions Age, race, and PSA threshold together affect the pre-test probability of an abnormal screening PSA result. Based on screening PSA distributions, stopping screening among men whose PSA < 3ng/ml means over 80% of white and Latino men age 70+ would stop further screening, and increasing the biopsy threshold to >10ng/ml has the greatest effect on reducing the number of older black men who will face biopsy decisions after screening.

2011-01-01

Introduction Total body dual-energy x-ray absorptiometry (DXA) data offer the opportunity to compare bone density of demographic groups across the entire skeleton. Methods The present study uses total body DXA data (Hologic QDR 4500A, Hologic Inc, Bedford MA) from the National Health and Nutrition Examination Survey (NHANES) 1999–2004 to examine bone mineral density (BMD) of the total body and selected skeletal subregions in a wide age range of adult men and women from three race/ethnic groups. Total body, lumbar spine, pelvis, right leg, and left arm BMD and lean mass from 13,091 adults age 20 years and older were used. The subregions were chosen to represent sites with different degrees of weight bearing. Results Mean BMD varied in expected ways for some demographic characteristics (men>women and non-Hispanic blacks>non-Hispanic whites) but not others (non-Hispanic whites>Mexican Americans). Differences in age patterns in BMD also emerged for some characteristics (sex) but not others (race/ethnicity). Differences in cross-sectional age patterns in BMD and lean mass by degree of weight-bearing in older adults were observed for the pelvis, leg and arm. Conclusion This information may be useful for generating hypotheses about age, race, and sex differences in fracture risk in the population. PMID:19048179

Social categories shape children's lives in subtle and powerful ways. Although research has assessed children's knowledge of social groups, most prominently race and gender, few studies have examined children's understanding of their own multiple social identities and how they intersect. This paper explores how children evaluate the importance and meaning of their racial and gender identities, and variation in these evaluations based on the child's own age, gender, and race. Participants were 222 Black, White, and Mixed-Race children (girls: n = 136; Mage = 9.94 years). Data were gathered in schools via 1-on-1 semistructured interviews. Analyses focused on specific measures of the importance and meaning of racial and gender identity for children. We found that: (a) children rate gender as a more important identity than race; (b) the meanings children ascribe to gender identity emphasized inequality and group difference whereas the meaning of race emphasized physical appearance and humanism/equality; and (c) children's assessments of importance and meaning varied as a function of child race and gender, but not age. The findings extend research on young children's social identity development and the role of culture and context in children's emerging racial and gender identities. Implications for identity theory and development and intergroup relations are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

African American youth who use marijuana are less likely to attend and complete treatment than white youth. Limited information is available on racial and age variation in treatment attendance and completion among adults who use marijuana. The current research examined differences in community-based substance abuse treatment attendance and completion between adult African American and white marijuana users in 2 independent samples from the US southeastern (N = 160; 70.6% African American) and mid-Atlantic (N = 450; 34.7% African American) regions. Attended at least 3 treatment sessions, successful treatment completion, number of days in treatment, and percentage of positive urine drug screens. Adjusted regression models examined the association of race, age, and the interaction of race and age with treatment attendance and completion. In the southeastern sample, successful treatment completion was significantly associated with the interaction of race and age (adjusted odds ratio = 1.35, 95% confidence interval = 1.08-1.69); whereas younger African Americans were less likely to complete treatment than older African Americans, age was unrelated to treatment completion among whites. In the mid-Atlantic sample, African Americans were significantly less likely to attend at least 3 treatment sessions (adjusted odds ratio = 0.37, 95% confidence interval = 0.23-0.58), and younger adult marijuana users were retained for fewer days in treatment (adjusted β = 0.13, 95% confidence interval = 0.27-2.48). Among African Americans, 37.9% (SD = 38.0) of urine drug screens tested positive for at least 1 illicit drug, and among whites, 34.2% (SD = 37.8%) tested positive; the percentage of positive urine drug screens was not associated with race or age. Among marijuana-using adults, treatment attendance and completion differ by race and age, and improvements in treatment completion may occur as some African Americans mature out of young adulthood.

To evaluate differences in amyloid deposition in a community-based cohort without dementia by age, sex, race, education, and APOE ε4 allele status. Recruited from the longitudinal Atherosclerosis Risk in Communities study, 329 participants without dementia, ages 67-88 years, were imaged using florbetapir PET at 3 US community sites (Washington County, Maryland; Forsyth County, North Carolina; and Jackson, Mississippi). Standardized uptake value ratios (SUVRs) were calculated; global cortical SUVR >1.2 was evaluated as the primary outcome. Age, race, sex, education level, and number of APOE ε4 alleles were evaluated in multivariable models including vascular risk factors, brain white matter hyperintensity and total intracranial volume, and cognitive status. A total of 141 of the participants (43%) were black. In multivariable models, odds of elevated SUVR was increased in participants with increasing age (odds ratio [OR] 1.63, 95% confidence interval [CI] 1.01-2.65 per 10 years of age) and black race (OR 2.08, 95% CI 1.23-3.51) but did not differ by educational level. Each ε4 allele was associated with increased odds of elevated SUVR (OR 2.65, 95% CI 1.61-4.39). In this community-based cohort without dementia, florbetapir uptake is associated with older age and APOE genotype. Black race was associated with higher SUVR, after adjusting for demographics, vascular risk factors, cognitive status, white matter hyperintensity volume, and APOE genotype, with effect sizes nearing those seen for APOE ε4. Replication of these findings is needed in other cohorts, and reasons for and consequences of these observed differences by race warrant further study. © 2016 American Academy of Neurology.

Absence of race- or gender-specific income disparities among full-time white and Asian general internists working for the Veterans Administration.

PubMed

Weeks, William B; Wallace, Amy E

2010-02-01

Gender-based, but not race-based, income disparities exist among general internists who practice medicine in the private sector. The aim of this study was to assess whether race- or gender-based income disparities existed among full-time white and Asian general internists who worked for the Veterans Health Administration of the US Department of Veterans Affairs (VA) between fiscal years 2004 and 2007, and whether any disparities changed after the VA enacted physician pay reform in early 2006. A retrospective study was conducted of all nonsupervisory, board-certified, full-time white or Asian VA general internists who did not change their location of practice between fiscal years 2004 and 2007. A longitudinal cohort design and linear regression modeling, adjusted for physician characteristics, were used to compare race- and gender-specific incomes in fiscal years 2004-2007. A total of 176 physicians were included in the study: 82 white males, 33 Asian males, 30 white females, and 31 Asian females. In all fiscal years examined, white males had the highest mean annual incomes, though not statistically significantly so. Regression analyses for fiscal years 2004 through 2006 revealed that physician age and years of service were predictive of total income. After physician pay reform was enacted, Asian male VA primary care physicians had higher annual incomes than did physicians in all other race or gender categories, after adjustment for age and years of VA service, though these differences were not statistically significant. No significant gender-based income disparities were noted among these white and Asian VA physicians. Our findings for white and Asian general internists suggest that the VA' s goal of maintaining a racially diverse workforce may have been effected, in part, through use of market pay among primary care general internists.

Poor grip strength is an indicator of frailty and a precursor to functional limitations. Although poor grip strength is more prevalent in older disabled African American women, little is known about the association between race and poverty-related disparities and grip strength in middle-aged men and women. We examined the cross-sectional relationship between race, socioeconomic status as assessed by household income, and hand grip strength in men and women in the Healthy Aging in Neighborhoods of Diversity across the Life Span study. General linear models examined grip strength (maximum of two trials on both sides) by race and household income adjusted for age, weight, height, hand pain, education, insurance status, family income, and two or more chronic conditions. Of 2,091 adults, 422(45.4%) were male, 509(54.8%) were African American, and 320 (34.5%) were living in households with incomes below 125% of the federal poverty level (low SES). In adjusted models, African American women had greater grip strength than White women independent of SES (low income household: 29.3 vs 26.9 kg and high income household: 30.5 vs. 28.3kg; P<.05 for both); whereas in men, only African Americans in the high income household group had better grip strength than Whites (46.3 vs. 43.2; P<.05). The relationship between grip strength, race and SES as assessed by household income varied in this cohort. Efforts to develop grip strength norms and cut points that indicate frailty and sarcopenia may need to be race- and income-specific.

Objectives. We investigated 50-year US trends in age at menarche by socioeconomic position (SEP) and race/ethnicity because data are scant and contradictory. Methods. We analyzed data by income and education for US-born non-Hispanic Black and White women aged 25 to 74 years in the National Health Examination Survey (NHES) I (1959–1962), National Health Examination and Nutrition Surveys (NHANES) I–III (1971–1994), and NHANES 1999–2008. Results. In NHES I, average age at menarche among White women in the 20th (lowest) versus 80th (highest) income percentiles was 0.26 years higher (95% confidence interval [CI] = −0.09, 0.61), but by NHANES 2005–2008 it had reversed and was −0.33 years lower (95% CI = −0.54, −0.11); no socioeconomic gradients occurred among Black women. The proportion with onset at younger than 11 years increased only among women with low SEP, among Blacks and Whites (P for trend < .05), and high rates of change occurred solely among Black women (all SEP strata) and low-income White women who underwent menarche before 1960. Conclusions. Trends in US age at menarche vary by SEP and race/ethnicity in ways that pose challenges to several leading clinical, public health, and social explanations for early age at menarche and that underscore why analyses must jointly include data on race/ethnicity and socioeconomic position. Future research is needed to explain these trends. PMID:25033121

Long-Term Trends in Black and White Mortality in the Rural United States: Evidence of a Race-Specific Rural Mortality Penalty.

PubMed

James, Wesley; Cossman, Jeralynn S

2017-01-01

The rural mortality penalty-growing disparities in rural-urban macro-level mortality rates-has persisted in the United States since the mid 1980s. Substantial intrarural differences exist: rural places of modest population size, close to urban areas, experience a greater mortality burden than the most rural locales. This research builds on recent findings by examining whether a race-specific rural mortality penalty exists; that is, are some rural areas more detrimental to black and/or white mortality than others? Using data from the Compressed Mortality File from 1968 to 2012, we calculate annual age-adjusted, race-specific mortality rates for all rural-urban regions designated by the Rural-Urban Continuum Codes. Indicators for population, socioeconomic status, and health infrastructure, as a proxy for access to care, are used as predictors of race-specific mortality in multivariable regression models. Three important results emerge from this analysis: (1) there is a substantial mortality disadvantage for both black and white rural Americans, (2) the most advantageous regions of mortality for blacks exhibit higher mortality than the most disadvantageous regions for whites, and (3) access to health care is a much stronger predictor of white mortality than black mortality. The rural mortality penalty is evident in race-specific mortality trends over time, with an added disadvantage in black mortality. The rate of mortality improvement for rural blacks and whites lags behind their same-race, urban counterparts, creating a diverging gap in race-specific mortality trends in rural America. © 2016 National Rural Health Association.

Background Studies examining the influence of maternal age and birth order on birthweight have not effectively disentangled the relative contributions of each factor to birthweight, especially as they may differ by race. Methods A population-based, cross-sectional study of North Carolina births from 1999 to 2003 was performed. Analysis was restricted to 510 288 singleton births from 28 to 42 weeks’ gestation with no congenital anomalies. Multivariable linear regression was used to model maternal age and birth order on birthweight, adjusting for infant sex, education, marital status, tobacco use and race. Results Mean birthweight was lower for non-Hispanic black individuals (NHB, 3166 g) compared with non-Hispanic white individuals (NHW, 3409 g) and Hispanic individuals (3348 g). Controlling for covariates, birthweight increased with maternal age until the early 30s. Race-specific modelling showed that the upper extremes of maternal age had a significant depressive effect on birthweight for NHW and NHB (35+ years, p<0.001), but only age less than 25 years was a significant contributor to lower birthweights for Hispanic individuals, p<0.0001. Among all racial subgroups, birth order had a greater influence on birthweight than maternal age, with the largest incremental increase from first to second births. Among NHB, birth order accounted for a smaller increment in birthweight than for NHW and Hispanic women. Conclusion Birth order exerts a greater influence on birthweight than maternal age, with signficantly different effects across racial subgroups. PMID:21081308

Racial disparities in colorectal cancer persist. Late stage at presentation and lack of stage-specific treatment may be contributing factors. We sought to evaluate the magnitude of disparity remaining after accounting for gender, stage, and treatment using predicted survival models. We used institutional tumor registries from a public health system (two hospitals) and a not-for-profit health system (nine hospitals) from 1995 to 2011. Demographics, stage at diagnosis, treatment, and survival were recorded. Hazard ratios (HRs) and predicted HRs were determined by Cox regression and postestimation analyses. There were 6,990 patients: 55.7 % white, 23.6 % African American, 15.1 % Hispanic, and 5.6 % Asian/other. Predictors of survival were surgery (HR 0.57, 95 % confidence interval [CI] 0.46-0.70), chemotherapy (HR 0.7, 95 % CI 0.62-0.79), female gender (HR 0.87, 95 % CI 0.83-0.90), age (HR 1.04, 95 % CI 1.03-1.05), and African American race (HR 3.6, 95 % CI 1.5-8.4). Balancing for stage, gender, and treatment reduced the predicted HRs for African Americans by 28 % and Hispanics by 17 %. In this model, African American and Hispanics still had the worst predicted HRs at younger ages, but whites had the worst predicted HR after age 75. Gender, stage, and treatment partially accounted for worsened survival in African Americans and Hispanics at all ages. At younger ages, race-related disparities remained which may reflect tumor biology or other unknown factors. Once gender, stage, and treatment are balanced at older ages, the increased mortality observed in whites may be due to factors such as comorbidities. Further system- and patient-level study is needed to investigate reasons for colorectal cancer survival disparities.

Implicit race bias has been shown to affect decisions and behaviors. It may also change perceptual experience by increasing perceived differences between social groups. We investigated how this phenomenon may be expressed at the neural level by testing whether the distributed blood-oxygenation-level-dependent (BOLD) patterns representing Black and White faces are more dissimilar in participants with higher implicit race bias. We used multivoxel pattern analysis to predict the race of faces participants were viewing. We successfully predicted the race of the faces on the basis of BOLD activation patterns in early occipital visual cortex, occipital face area, and fusiform face area (FFA). Whereas BOLD activation patterns in early visual regions, likely reflecting different perceptual features, allowed successful prediction for all participants, successful prediction on the basis of BOLD activation patterns in FFA, a high-level face-processing region, was restricted to participants with high pro-White bias. These findings suggest that stronger implicit pro-White bias decreases the similarity of neural representations of Black and White faces. PMID:23300228

Understanding how race/ethnicity and gender define age-trajectories of disability: an intersectionality approach.

Warner, David F; Brown, Tyson H

2011-04-01

A number of studies have demonstrated wide disparities in health among racial/ethnic groups and by gender, yet few have examined how race/ethnicity and gender intersect or combine to affect the health of older adults. The tendency of prior research to treat race/ethnicity and gender separately has potentially obscured important differences in how health is produced and maintained, undermining efforts to eliminate health disparities. The current study extends previous research by taking an intersectionality approach (Mullings & Schulz, 2006), grounded in life course theory, conceptualizing and modeling trajectories of functional limitations as dynamic life course processes that are jointly and simultaneously defined by race/ethnicity and gender. Data from the nationally representative 1994-2006 US Health and Retirement Study and growth curve models are utilized to examine racial/ethnic/gender differences in intra-individual change in functional limitations among White, Black and Mexican American Men and Women, and the extent to which differences in life course capital account for group disparities in initial health status and rates of change with age. Results support an intersectionality approach, with all demographic groups exhibiting worse functional limitation trajectories than White Men. Whereas White Men had the lowest disability levels at baseline, White Women and racial/ethnic minority Men had intermediate disability levels and Black and Hispanic Women had the highest disability levels. These health disparities remained stable with age-except among Black Women who experience a trajectory of accelerated disablement. Dissimilar early life social origins, adult socioeconomic status, marital status, and health behaviors explain the racial/ethnic disparities in functional limitations among Men but only partially explain the disparities among Women. Net of controls for life course capital, Women of all racial/ethnic groups have higher levels of functional

Neuropsychological tests, including tests of language ability, are frequently used to differentiate normal from pathological cognitive aging. However, language can be particularly difficult to assess in a standardized manner in cross-cultural studies and in patients from different educational and cultural backgrounds. This study examined the effects of age, gender, education and race on performance of two language tests: the animal fluency task (AFT) and the Indiana University Token Test (IUTT). We report population-based normative data on these tests from two combined ethnically divergent, cognitively normal, representative population samples of older adults. Participants aged > or =65 years from the Monongahela-Youghiogheny Healthy Aging Team (MYHAT) and from the Indianapolis Study of Health and Aging (ISHA) were selected based on (1) a Clinical Dementia Rating (CDR) score of 0; (2) non-missing baseline language test data; and (3) race self-reported as African-American or white. The combined sample (n = 1885) was 28.1% African-American. Multivariate ordinal logistic regression was used to model the effects of demographic characteristics on test scores. On both language tests, better performance was significantly associated with higher education, younger age, and white race. On the IUTT, better performance was also associated with female gender. We found no significant interactions between age and sex, and between race and education. Age and education are more potent variables than are race and gender influencing performance on these language tests. Demographically stratified normative tables for these measures can be used to guide test interpretation and aid clinical diagnosis of impaired cognition.

Healthy Aging Among Older Black and White Men: What Is the Role of Mastery?

2018-01-11

This research explores black-white differences in healthy aging and investigates whether mastery acts as a buffer against poor health for older black and white men. Using data from the Health and Retirement Study (HRS) (2008-2012), a series of binary logit models were created to assess healthy aging over a 2-year period. Healthy aging was defined as good subjective health and free of disability at both waves. Mastery was lagged, and analyses (n = 4,892) controlled for social and health factors. Black-white disparities in healthy aging were observed, where older black men had lower odds of healthy aging. Mastery was associated with higher odds of healthy aging, and race moderated the relationship between mastery and healthy aging. The predicted probability of healthy aging was relatively flat across all levels of mastery among black men, yet white men saw consistent gains in the probability of healthy aging with higher levels of mastery. In race-stratified models, mastery was not a significant predictor of healthy aging among black men. High levels of mastery are linked to positive health-often acting as a buffer against stressful life events. However, among older black men, higher levels of mastery did not necessarily equate to healthy aging. © The Author 2017.

Examine interactive relations of race and poverty status with cardiovascular disease (CVD) risk factors in a socioeconomically diverse sample of urban-dwelling African American (AA) and White adults. Participants were 2,270 AAs and Whites (57% AA; 57% female; ages 30-64 years) who completed the first wave of the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study. CVD risk factors assessed included body mass index (BMI), waist circumference (WC), total cholesterol (TC), high- and low-density lipoprotein cholesterol (HDL-C, LDL-C), triglycerides (TG), glycated hemoglobin (HbA1c), high-sensitivity C-reactive protein (CRP), and systolic, diastolic, and pulse pressure (SBP, DBP, PP). Interactive and independent relations of race, poverty status, and sex were examined for each outcome via ordinary least squares regression adjusted for age, education, literacy, substance use, depressive symptoms, perceived health care barriers, medical co-morbidities, and medications. Significant interactions of race and poverty status (p's < .05) indicated that AAs living in poverty had lower BMI and WC and higher HDL-C than non-poverty AAs, whereas Whites living in poverty had higher BMI and WC and lower HDL-C than non-poverty Whites. Main effects of race revealed that AAs had higher levels of HbA1c, SBP, and PP, and Whites had higher levels of TC, LDL-C and TG (p's < .05). Poverty status moderated race differences for BMI, WC, and HDL-C, conveying increased risk among Whites living in poverty, but reduced risk in their AA counterparts. Race differences for six additional risk factors withstood extensive statistical adjustments including SES indicators.

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. PMID:22279425

There are concerns over nonmedical use of prescription stimulants among youths, but little is known about the extent of use among young Asian-Americans, Native Hawaiians/Pacific Islanders (NHs/PIs), and mixed-race individuals—the fastest growing segments of the U.S. population. We examined prevalences and correlates of nonmedical stimulant use (NMSU) and disorder (StiUD) for these underrecognized groups. Whites were included as a comparison. Data were from young individuals aged 12–34 years in the 2005–2012 National Surveys on Drug Use and Health. We used logistic regression to estimate odds of past-year NMSU status. Significant yearly increases in lifetime NMSU prevalence were noted in Whites only. NHs/PIs (lifetime 7.33%, past-year 2.72%) and mixed-race individuals (10.20%, 2.82%) did not differ from Whites in NMSU prevalence (11.68%, 3.15%). Asian-Americans (lifetime 3.83%, past-year 0.90%) had lower prevalences than Whites. In each racial/ethnic group, “Methamphetamine/Desoxyn/Methedrine or Ritalin” was more commonly used than other stimulant groups; “got them from a friend/relative for free” and “bought them from a friends/relative” were among the most common sources. Females had greater odds than males of NMSU (among White, NH/PI, mixed-race individuals) and StiUD (among mixed-race individuals). Young adults (aged 18–25) had elevated odds of NMSU (White, NH/PI); adolescents had elevated odds of StiUD (White, mixed-race). Other substance use (especially marijuana, other prescription drugs) increased odds of NMSU and StiUD. NHs/PIs and mixed-race individuals were as likely as Whites to misuse stimulants. Research is needed to delineate health consequences of NMSU and inform prevention efforts for these understudied, rapidly-growing populations. PMID:25263275

Objective To describe national trends in discretionary calories from sugar sweetened beverage (SSB) and snacks by age-specific body weight categories and by age- and weight-specific race/ethnicity groups. Examining these sub-populations is important as population averages may mask important differences. Design and Methods We used 24-hour dietary recall data obtained from the National Health and Nutrition Examination Survey 2003–2010 among children aged 2 to 19 (N=14,092). Logistic and linear regression methods were used to adjust for multiple covariates and survey design. Results The number of calories from SSBs declined significantly for nearly all age-specific body weight groups. Among overweight or obese children, significant declines in the number of calories from SSBs were observed among Hispanic children aged 2 to 5 (117 kcal vs. 174 kcal) and white adolescents aged 12 to 19 (299 kcal vs. 365 kcal). Significant declines in the number of calories from salty snacks were observed among white children aged 2 to 5 (192 kcal to 134 kcal) and 6 to 11 (273 kcal vs. 200 kcal). Conclusions The decrease in SSB consumption and increase in snack consumption observed in prior research are not uniform when children are examined within sub-groups accounting for age, weight and race/ethnicity.

Study Objectives: Sleep duration has been associated with risk of dementia and stroke, but few studies have investigated the relationship between sleep duration and brain MRI measures, particularly in middle age. Methods: In a prospective cohort of 613 black and white adults (mean age = 45.4 years) enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study, participants reported typical sleep duration, dichotomized into moderate sleep duration (> 6 to ≤ 8 h) and short sleep duration (≤ 6 h) at baseline (2005–2006). Five years later, we obtained brain MRI markers of white matter including fractional anisotropy, mean diffusivity, and white matter hyperintensities. Results: Compared to moderate sleepers, short sleepers had an elevated ratio of white matter hyperintensities to normal tissue in the parietal region (OR = 2.31, 95% CI: 1.47, 3.61) adjusted for age, race/sex, education, hypertension, stroke/TIA, depression, smoking status, and physical activity. White matter diffusivity was also higher, approximately a 0.2 standard deviation difference, in frontal, parietal, and temporal white matter regions, among those reporting shorter sleep duration in (P < 0.05 for all). Conclusions: Short sleep duration was associated with worse markers of white matter integrity in midlife. These mid-life differences in white matter may underlie the link between poor sleep and risk of dementia and stroke.

Aim: To utilise a novel method for making measurements in the anterior chamber in order to compare the anterior chamber angles of people of European, African, and east Asian descent aged 40 years and over. Methods: A cross sectional study on 15 people of each sex from each decade from the 40s to the 70s, from each of three racial groups—black, white, and Chinese Singaporeans. Biometric gonioscopy (BG) utilises a slit lamp mounted reticule to make measurements from the apparent iris insertion to Schwalbe's line through a Goldmann one mirror goniolens. The main outcome measures were BG measurements of the anterior chamber angle as detailed above. Results: There was no significant difference in angle measurement between black, white, and Chinese races in this study. However, at younger ages people of Chinese race appeared to have deeper angles than white or black people, whereas the angles of older Chinese were significantly narrower (p = 0.004 for the difference in slope of BG by age between Chinese and both black and white people). Conclusion: The failure to detect a difference in angle measurements between these groups was surprising, given the much higher prevalence of angle closure among Chinese. It appears that the overall apparent similarity of BG means between Chinese and Western populations may mask very different trends with age. The apparently more rapid decline in angle width measurements with age among Chinese may be due to the higher prevalence of cataract or “creeping angle closure.” However, longitudinal inferences from cross sectional data are problematic, and this may represent a cohort phenomenon caused by the increasing prevalence of myopia in the younger Singaporean population.

Gender and racial disparities in injury mortality have been well established, but less is known regarding differences in fracture-related hospitalizations across the age span. Cross-sectional analysis of annual incident fracture hospital admissions used statewide acute care hospital discharge data (Statewide Program and Research Cooperative System) for non-Hispanic White (n = 138,763) and non-Hispanic Black (n = 19,588) residents of New York State between 2000 and 2002. US census data with intercensal estimates were used to ascertain the population at risk. Gender- and race-specific incident fracture was calculated in 5-year age intervals. The χ test was used to analyze categorical variables. Mechanisms of injury vary by race and gender in their relative contribution to injury-related fractures across the age span. Black males exhibited higher fracture incidence until approximately age 62, while incidence in women diverged around age 45. Total motor vehicle traffic-related fracture hospitalization is bimodal in Whites but not in Blacks. Over the life span, all groups exhibited bimodal pedestrian fractures with pedestrian fractures accounting for 8.8% and 2.5% of all fractures in Blacks and Whites, respectively. Racial disparities were present from preschool through age 70. Violence-related fractures were 10 times higher in Blacks, accounting for 18.2% of hospitalizations. Black males exhibit higher fracture incidence due to violence by age 5 and higher gun violence by age 10; both remain elevated through age 75. Despite historical studies demonstrating higher bone density in Blacks, this study found racial disparities with increased fracture risk in both Black children and adults across most nonfall-related injury mechanisms examined.

This study investigates the importance of sociodemographic and geographical characteristics for suicide risks in the South African urban context. Suicide epidemiology is under-researched in low- and middle-income countries, and such knowledge is important not only for local and national policy, but also for a global understanding of the phenomenon. Sex-specific crude and adjusted odds ratios (95% confidence intervals) for suicide by age, race, and city are assessed using logistic regression. Cases aged 45+ years, classified as "Coloured" (a category denoting mixed racial origin), and living in Cape Town are used as reference groups. Additionally, the proportion of leading suicide methods within groups was estimated (95% confidence intervals). For males, compared with each reference group, the odds of suicide are significantly higher during middle adulthood, among Asians and particularly among Whites, and among residents of all but one city. Patterns for women differ in magnitude and distribution. Suicide odds are significantly higher in all age groups, particularly 15-24 years, among Whites, and among residents of all other cities, particularly Nelson Mandela or Buffalo City. Males living in Tshwane and Black females have lower odds of suicide. The distribution of methods across age, race, and city groups varies little for males but substantially for females. Age, race, and city play independent roles in sex-specific suicide rates. As for high-income settings, age, race, method and city are important in sex-specific suicide in the urban South African context. Possible underlying mechanisms deserve greater attention for context-relevant preventive efforts.

Azilsartan medoxomil (AZL-M) is an angiotensin II receptor blocker approved to treat hypertension. After oral dosing, AZL-M is quickly hydrolyzed to azilsartan (AZL). The aims of this study were to assess the effects of age, sex, and race on the pharmacokinetics of AZL-M in healthy subjects, as well as safety and tolerability. Sixty-one healthy adults were enrolled in this phase I, single-blind, randomized placebo-controlled study (placebo control was for assessment of safety/tolerability only). Subjects were stratified by age (18-45 vs. 65-85 years), sex, and race (black vs. white) and given oral AZL-M 60 mg (3 × 20 mg capsules) or placebo as a single dose (Day 1) and consecutive daily doses (Days 4-8) (6:2 ratio for AZL-M:placebo per group). Pharmacokinetics were evaluated (AZL-M patients only) on Days 1-3 and 8-9 and safety/tolerability was monitored. Age, sex, and race had no clinically meaningful effect on AZL exposures after single or multiple dosing. Pharmacokinetic parameters remained similar between Days 1 and 8 for each age, sex, and race subgroup. The frequency of adverse events was similar for AZL-M (32%) and placebo (29%). No discontinuations or serious adverse events occurred. Based on these pharmacokinetic and safety/tolerability findings, no AZL-M dose adjustments are required based on age, sex, or race (black/white).

Body composition and blood pressure in children based on age, race, and sex.

Brandon, L J; Fillingim, J

1993-01-01

We evaluated 675 nine- and twelve-year-old children for body composition and circulatory differences based on age, race, and sex. The specific variables measured included height, weight, triceps and subscapula skinfolds, body mass index, percentage fat, fat-free weight, and systolic, diastolic, and mean arterial blood pressures. A 2 x 2 x 2 factorial multiple analysis of variance (MANOVA) test of significance showed body composition and blood pressure differences (P < .01) for race, age, and sex. The univariate test of the specific variables within the factors showed that black children had higher fat-free weights and lower fat levels but higher blood pressure values (P < .05) than white children. Boys had lower fat levels than girls, and the older children had higher values on the body composition variables but not on blood pressure. Zero order correlations between body composition and blood pressure ranged from 0.14 to 0.55; systolic blood pressure and body weight shared the highest correlation. These data show that, although black children have less body fat than white children, they are heavier and have higher blood pressure. We hypothesize that some aspect of fat-free body weight may contribute to hypertension in black individuals.

Epidemiological research suggests racial differences in the presentation of eating disorder symptoms. However, no studies have examined associations between race and eating disorder symptom trajectories across youth and adolescence, which is necessary to inform culturally sensitive prevention programs. The purpose of the current study was to examine the trajectories of eating disorder symptoms from childhood to young adulthood and to examine whether race was associated with trajectory group membership. Data were drawn from 2,305 Black and White girls who participated in a community-based longitudinal cohort study (Pittsburgh Girls Study) examining the development of psychopathology. The child and adult versions of the Eating Attitudes Test assessed self-reported eating disorder symptoms at six time points between ages 9 and 21 years. Growth mixture modeling was used to examine developmental trajectories of dieting, bulimia/food preoccupation, and total eating disorder symptom scores. Given potential confounds with race and disordered eating, financial strain (i.e., receiving public assistance) and weight were included as covariates. Four to six distinct developmental patterns were found across eating disorder symptoms, including none, increasing, decreasing, or increasing-decreasing trajectories. Black girls had a greater likelihood of being in the decreasing trajectories for dieting, bulimia/food preoccupation, and total eating disorder symptom scores. White girls were more likely to follow increasing trajectories of dieting and total eating disorder symptom scores compared to Black girls. These results highlight the importance of examining the influence of racial background on eating disorder symptoms and the potential need for differences in the timing and focus of prevention interventions in these groups.

Reference values and age-related changes of the wall thickness of the abdominal aorta have not been described in the general population. We characterized age-, race-, and gender-specific distributions, and yearly rates of change of mean aortic wall thickness (MAWT), and associations between MAWT and cardiovascular risk factors in a multi-ethnic population-based probability sample. Magnetic resonance imaging measurements of MAWT were performed on 2466 free-living white, black, and Hispanic adult subjects. MAWT race/ethnicity- and gender-specific percentile values across age were estimated using regression analyses. MAWT was greater in men than in women and increased linearly with age in all the groups and across all the percentiles. Hispanic women had the thinnest and black men the thickest aortas. Black men had the highest and white women the lowest age-related MAWT increase. Age, gender, ethnicity, smoking status, systolic blood pressure, low-density lipoprotein-cholesterol levels, high-density lipoprotein-cholesterol levels, and fasting glucose levels were independent predictors of MAWT. Age, gender, and racial/ethnic differences in MAWT distributions exist in the general population. Such differences should be considered in future investigations assessing aortic atherosclerosis and the effects of anti-atherosclerotic therapies. Published by Mosby, Inc.

Race- and poverty-related disparities in physical function are well documented, though little is known about effects of race and poverty on functional decline and the progression of disability. We examined cross-sectional and longitudinal relationships between race, poverty and lower extremity function using data from moderately to severely disabled women in the U.S. Women's Health and Aging Study. Severity of lower extremity functional limitation was determined from scaled responses of reported difficulty walking (1/4) mile, walking across a room, climbing stairs, and stooping, crouching or kneeling. Usual walking speed assessed over 4m was our objective measure of function. Of the 996 women who described themselves as black or white, 284 (29%) were black and 367 (37%) were living at or below 100% of the federal poverty level. Independent of demographic and health-related factors, among white women, the poor exhibited consistently worse lower extremity function than the non-poor; this association, however, was not observed in black women. Among the non-poor, black women had slower walking speeds, and reported more limitation in lower extremity function than their non-poor white counterparts, even after adjusting for demographic variables and health-related characteristics. After 3 years, accounting for baseline function, demographic and health-related factors, race and poverty status were unrelated to functional decline. Thus, while race and poverty status were associated with functional deficits in old age, they do not appear to impact the rate of functional decline or progression of disability over 3 years.

Current literature shows different findings on the contemporary trends of distant-stage prostate cancer incidence, in part, due to low study population coverage and wide age groupings. This study aimed to examine the stage-specific incidence rates and trends of prostate cancer by age (5-year grouping), race, and ethnicity using nationwide cancer registry data. Data on prostate cancer cases came from the 2004-2014 United States Cancer Statistics data set. We calculated stage-specific incidence and 95% confidence intervals by age (5-year age grouping), race, and ethnicity. To measure the changes in rates over time, we calculated annual percentage change (APC). We identified 2,137,054 incident prostate cancers diagnosed during 2004-2014, with an age-adjusted incidence rate of 453.8 per 100,000. Distant-stage prostate cancer incidence significantly decreased during 2004-2010 (APC = -1.2) and increased during 2010-2014 (APC = 3.3). Significant increases in distant prostate cancer incidence also occurred in men aged older than or equal to 50 years except men aged 65-74 and older than or equal to 85 years, in men with white race (APC = 3.9), and non-Hispanic ethnicity (APC = 3.5). Using data representing over 99% of U.S. population, we found that incidence rates of distant-stage prostate cancer significantly increased during 2010-2014 among men in certain ages, in white, and with non-Hispanic ethnicity.

Understanding How Race/Ethnicity and Gender Define Age-Trajectories of Disability: An Intersectionality Approach

A number of studies have demonstrated wide disparities in health among racial/ethnic groups and by gender, yet few have examined how race/ethnicity and gender intersect or combine to affect the health of older adults. The tendency of prior research to treat race/ethnicity and gender separately has potentially obscured important differences in how health is produced and maintained, undermining efforts to eliminate health disparities. The current study extends previous research by taking an intersectionality approach (Mullings & Schulz, 2006), grounded in life course theory, conceptualizing and modeling trajectories of functional limitations as dynamic life course processes that are jointly and simultaneously defined by race/ethnicity and gender. Data from the nationally representative 1994–2006 US Health and Retirement Study and growth curve models are utilized to examine racial/ethnic/gender differences in intra-individual change in functional limitations among White, Black and Mexican American Men and Women, and the extent to which differences in life course capital account for group disparities in initial health status and rates of change with age. Results support an intersectionality approach, with all demographic groups exhibiting worse functional limitation trajectories than White Men. Whereas White Men had the lowest disability levels at baseline, White Women and racial/ethnic minority Men had intermediate disability levels and Black and Hispanic Women had the highest disability levels. These health disparities remained stable with age—except among Black Women who experience a trajectory of accelerated disablement. Dissimilar early life social origins, adult socioeconomic status, marital status, and health behaviors explain the racial/ethnic disparities in functional limitations among Men but only partially explain the disparities among Women. Net of controls for life course capital, Women of all racial/ethnic groups have higher levels of functional

Heart disease is the leading cause of death in the United States. In 2015, heart disease accounted for approximately 630,000 deaths, representing one in four deaths in the United States. Although heart disease death rates decreased 68% for the total population from 1968 to 2015, marked disparities in decreases exist by race and state. 1968-2015. The National Vital Statistics System (NVSS) data on deaths in the United States were abstracted for heart disease using diagnosis codes from the eighth, ninth, and tenth revisions of the International Classification of Diseases (ICD-8, ICD-9, and ICD-10) for 1968-2015. Population estimates were obtained from NVSS files. National and state-specific heart disease death rates for the total population and by race for adults aged ≥35 years were calculated for 1968-2015. National and state-specific black-white heart disease mortality ratios also were calculated. Death rates were age standardized to the 2000 U.S. standard population. Joinpoint regression was used to perform time trend analyses. From 1968 to 2015, heart disease death rates decreased for the total U.S. population among adults aged ≥35 years, from 1,034.5 to 327.2 per 100,000 population, respectively, with variations in the magnitude of decreases by race and state. Rates decreased for the total population an average of 2.4% per year, with greater average decreases among whites (2.4% per year) than blacks (2.2% per year). At the national level, heart disease death rates for blacks and whites were similar at the start of the study period (1968) but began to diverge in the late 1970s, when rates for blacks plateaued while rates for whites continued to decrease. Heart disease death rates among blacks remained higher than among whites for the remainder of the study period. Nationwide, the black-white ratio of heart disease death rates increased from 1.04 in 1968 to 1.21 in 2015, with large increases occurring during the 1970s and 1980s followed by small but steady

Race, embodiment and later life: Re-animating aging bodies of color.

PubMed

Rajan-Rankin, Sweta

2018-06-01

This theoretical essay examines the intersections between race, ethnicity and old age from an inter-disciplinary lens. Drawing on cultural gerontology (especially embodied aging studies) and post-colonial perspectives on aging, it explores how an emphasis on the body and embodiment can serve as a conceptual lens for understanding racialized aging bodies. A tentative framework for analysis is proposed. The concept of exile explores how bodies of color and older bodies are denigrated through the hegemonic (white, youth-centered, masculinist) gaze. Re-animation can take place by transcending double-consciousness: 'seeing beyond' the dominant gaze. Othering and otherness are explored in relation to both raced and aging bodies. The limits of ethnic aging are scrutinized at an epistemic level, simultaneously informing, and obscuring the understanding of lived experiences of racialized ethnic minorities in old age. Visible and invisible difference provide a way of unpacking the simultaneous hypervisibility of older (female) bodies of color, and their invisibility in institutional and policy discourses. De-coloniality is considered, by exploring ways to resist hegemonic power through embodied ways of knowing. This article concludes by exploring how recent methodological innovations - especially the visual and sensory turn - can offer new ways of understanding the lived experiences of aging bodies of color.

The rules of implicit evaluation by race, religion, and age.

Axt, Jordan R; Ebersole, Charles R; Nosek, Brian A

The social world is stratified. Social hierarchies are known but often disavowed as anachronisms or unjust. Nonetheless, hierarchies may persist in social memory. In three studies (total N > 200,000), we found evidence of social hierarchies in implicit evaluation by race, religion, and age. Participants implicitly evaluated their own racial group most positively and the remaining racial groups in accordance with the following hierarchy: Whites > Asians > Blacks > Hispanics. Similarly, participants implicitly evaluated their own religion most positively and the remaining religions in accordance with the following hierarchy: Christianity > Judaism > Hinduism or Buddhism > Islam. In a final study, participants of all ages implicitly evaluated age groups following this rule: children > young adults > middle-age adults > older adults. These results suggest that the rules of social evaluation are pervasively embedded in culture and mind. © The Author(s) 2014.

What a white shame: race, gender, and white shame in the relational economy of primary health care organizations in England.

PubMed

Hunter, Shona

2010-01-01

This paper considers the relationship between white shame in contemporary UK health care contexts and historically idealized forms of white pride derived from nineteenth-century British colonialism. It uses excerpts from qualitative interview material to highlight the contemporary figures of the “white worried man” and the “white women savior” and the relationship between them. Through this, it explores how shifts from white pride to white shame reflect shifts in the focus of whiteness away from civilizing the racialized Other to civilizing the white self. Through this analysis, it further complicates shame theory arguing for an understanding of [white] shame as constituted through a relational economy, differentiated through class and gender as well as race.

African Americans (AAs) have a higher prevalence of extreme ischemic white matter hyperintensities (WMHs) on magnetic resonance imaging (MRI) than do European Americans (EAs) based on the Cardiovascular Health Study (CHS) score. Ischemic white matter disease, limited to the deep white matter, may be biologically distinct from disease in other regions and may reflect a previously observed trend toward an increased risk of subcortical lacunar infarcts in AAs. We hypothesized that extreme deep WMH volume (DWMV) or periventricular volume (PV) may also have a higher prevalence in AAs. Thus, we studied extreme CHS scores and extreme DWMV and PV in a healthy population enriched for cardiovascular disease risk factors. We imaged the brains of 593 subjects who were first-degree relatives of probands with early onset coronary disease prior to 60 years of age. WMHs were manually delineated on 3-tesla cranial MRI by a trained radiology reader; the location and volume of lesions were characterized using automated software. DWMV and PV were measured directly with automated software, and the CHS score was determined by a neuroradiologist. Volumes were characterized as being in the upper 25% versus lower 75% of total lesion volume. Volumes in the upper versus the remaining quartiles were examined for AA versus EA race using multiple logistic regression (generalized estimating equations adjusted for family relatedness) and adjusted for major vascular disease risk factors including age ≥55 years versus <55, sex, current smoking, obesity, hypertension, diabetes and low-density lipoprotein >160 mg/dl. Participants were 58% women and 37% AAs, with a mean age of 51.5 ± 11.0 years (range, 29-74 years). AAs had significantly higher odds of having extreme DWMVs (odds ratio, OR, 1.8; 95% confidence interval, CI, 1.2-2.9; p = 0.0076) independently of age, sex, hypertension and all other risk factors. AAs also had significantly higher odds of having extreme CHS scores ≥3 (OR, 1.3; 95% CI

To describe the burden of dysglycemia-abnormal glucose metabolism indicative of diabetes or high risk for diabetes-among U.S. women of childbearing age, focusing on differences by race/ethnicity. Using U.S. National Health and Nutrition Examination Survey data (1999-2008), we calculated the burden of dysglycemia (i.e., prediabetes or diabetes from measures of fasting glucose, A1C, and self-report) in nonpregnant women of childbearing age (15-49 years) by race/ethnicity status. We estimated prevalence risk ratios (PRRs) for dysglycemia in subpopulations stratified by BMI (measured as kilograms divided by the square of height in meters), using predicted marginal estimates and adjusting for age, waist circumference, C-reactive protein, and socioeconomic factors. Based on data from 7,162 nonpregnant women, representing>59,000,000 women nationwide, 19% (95% CI 17.2-20.9) had some level of dysglycemia, with higher crude prevalence among non-Hispanic blacks and Mexican Americans vs. non-Hispanic whites (26.3% [95% CI 22.3-30.8] and 23.8% [19.5-28.7] vs. 16.8% [14.4-19.6], respectively). In women with BMI<25 kg/m2, dysglycemia prevalence was roughly twice as high in both non-Hispanic blacks and Mexican Americans vs. non-Hispanic whites. This relative increase persisted in adjusted models (PRRadj 1.86 [1.16-2.98] and 2.23 [1.38-3.60] for non-Hispanic blacks and Mexican Americans, respectively). For women with BMI 25-29.99 kg/m2, only non-Hispanic blacks showed increased prevalence vs. non-Hispanic whites (PRRadj 1.55 [1.03-2.34] and 1.28 [0.73-2.26] for non-Hispanic blacks and Mexican Americans, respectively). In women with BMI>30 kg/m2, there was no significant increase in prevalence of dysglycemia by race/ethnicity category. Our findings show that dysglycemia affects a significant portion of U.S. women of childbearing age and that disparities by race/ethnicity are most prominent in the nonoverweight/nonobese.

Age trajectories of everyday cognition in African American and White older adults under prompted and unprompted conditions

We investigated how race and verbal prompting interacted with age to predict age trajectories on a performance-based measure of everyday cognition. African American (n = 727) and White (n = 2052) older adults from the ACTIVE clinical trial were given the Observed Tasks of Daily Living (OTDL; a performance-based measure of medication management/finances/telephone use) at baseline and 1-, 2-, 3-, 5-, and 10-year follow-ups. When participants said “I don't know” or did not respond, they received a standardised verbal prompt, which served only as a cue to initiate the first step. At each occasion, unprompted (sum of items correct without prompting) and prompted (sum of correct prompted and unprompted items) scores were derived for each participant. Mixed effects models for change were used to determine the age trajectories of OTDL performance by race. When not prompted, African Americans demonstrated more rapid decline in OTDL performance than Whites, especially after age 80. When prompted, both groups had improved performance and evinced shallower decline, although African Americans continued to demonstrate a slightly more rapid decline. Simple prompting attenuated age-related changes of African Americans and Whites on a measure of everyday cognition. Prompting may be especially helpful for older African Americans. PMID:26480946

To examine change from 1991 to 2001 in disability-free life expectancy in the age range 60–90 by gender, race, and education in the United States. Mortality is estimated over two 10-year follow-up periods for persons in the National Health Interview Surveys of 1986/1987 and 1996/1997. Vital status is ascertained through the National Death Index. Disability prevalence is estimated from the National Health and Nutrition Examination Surveys of 1988–1994 and 1999–2002. Disability is defined as ability to perform four activities of daily living without difficulty. Disability-free life expectancy increased only among white men. Disabled life expectancy increased for all groups—black and white men and women. Racial differences in disability-free life expectancy widened among men; gender differences were reduced among whites. Expansion of socioeconomic differentials in disability-free life at older ages occurred among white men and women and black women. The 1990s was a period where the increased years of life between ages 60 and 90 were concentrated in disabled years for most population groups. PMID:29681672

Background Although there are significant differences in prevalence of substance use between African-American and White adolescents, few studies have examined racial differences in developmental patterns of substance use, especially during the important developmental transition from adolescence to young adulthood. This study examines racial differences in trajectories of heavy drinking and regular marijuana use from adolescence into young adulthood. Methods A community-based sample of non-Hispanic African-American (n = 276) and non-Hispanic White (n = 211) males was analyzed to identify trajectories from ages 13 through 24. Results Initial analyses indicated race differences in heavy drinking and regular marijuana use trajectories. African Americans were more likely than Whites to be members of the nonheavy drinkers/nondrinkers group and less likely to be members of the early-onset heavy drinkers group. The former were also more likely than the latter to be members of the late-onset regular marijuana use group. Separate analyses by race indicated differences in heavy drinking for African Americans and Whites. A 2-group model for heavy drinking fit best for African Americans, whereas a 4-group solution fit best for Whites. For regular marijuana use, a similar 4-group solution fit for both races, although group proportions differed. Conclusions Within-race analyses indicated that there were clear race differences in the long-term patterns of alcohol use; regular marijuana use patterns were more similar. Extended follow ups are needed to examine differences and similarities in maturation processes for African-American and White males. For both races, prevention and intervention efforts are necessary into young adulthood. PMID:21908109

We estimated health care expenditures associated with overweight and obesity and examined the influence of age, race, and gender. Using 1998 Medical Expenditure Panel Survey data, we employed 2-stage modeling to estimate annual health care expenditures associated with high body mass index (BMI) and examine interactions between demographic factors and BMI. Overall, the mean per capita annual health care expenditure (converted to December 2003 dollars) was $3338 before adjustment. While the adjusted expenditure was $2127 (90% confidence interval [CI]=$1927, $2362) for a typical normal-weight White woman aged 35 to 44 years, expenditures were $2358 (90% CI=$2128, $2604) for women with BMIs of 25 to 29.9 kg/m(2), $2873 (90% CI=$2530, $3236) for women with BMIs of 30 to 34.9 kg/m(2), $3058 (90% CI=$2529, $3630) for women with BMIs of 35 to 39.9 kg/m(2), and $3506 (90% CI=$2912, $4228) for women with BMIs of 40 kg/m(2) or higher. Expenditures related to higher BMI rose dramatically among White and older adults but not among Blacks or those younger than 35 years. We found no interaction between BMI and gender. Health care costs associated with overweight and obesity are substantial and vary according to race and age.

Large-scale surveys have shown elevated risk for many indicators of substance abuse among Native American and Mixed-Race adolescents compared to other minority groups in the United States. This study examined underlying contextual factors associated with substance abuse among a nationally representative sample of White, Native American, and Mixed-Race adolescents 12-17 years of age, using combined datasets from the National Survey on Drug Use and Health (NSDUH, 2006-2009, N = 46,675, 48.77 % female). Native American adolescents displayed the highest rate of past-month binge drinking and past-year illicit drug use (14.06 % and 30.91%, respectively). Results of a logistic regression that included seven predictors of social bonding, individual views of substance use, and delinquent peer affiliations showed that friendships with delinquent peers and negative views of substance use were associated significantly with both substance abuse outcomes among White and Mixed-Race adolescents and, to a lesser extent, Native American adolescents. The association of parental disapproval with binge drinking was stronger for White than for Native American adolescents. Greater attention to specific measures reflecting racial groups’ contextual and historical differences may be needed to delineate mechanisms that discourage substance abuse among at-risk minority adolescent populations.

Surgical Sterilization, Regret, and Race: Contemporary Patterns*

Shreffler, Karina M.; McQuillan, Julia; Greil, Arthur L.; Johnson, David R.

2014-01-01

Surgical sterilization is a relatively permanent form of contraception that has been disproportionately used by Black, Hispanic, and Native American women in the United States in the past. We use a nationally representative sample of 4,609 women ages 25 to 45 to determine whether sterilization continues to be more common and consequential by race for reproductive-age women. Results indicate that Native American and Black women are more likely to be sterilized than non-Hispanic White women, and Hispanic and Native American women are more likely than non-Hispanic White women to report that their sterilization surgeries prevent them from conceiving children they want. Reasons for sterilization differ significantly by race. These findings suggest that stratified reproduction has not ended in the United States and that the patterns and consequences of sterilization continue to vary by race. PMID:25592919

Race Differences in the Association of Spiritual Experiences and Life Satisfaction in Older Age

Skarupski, Kimberly A.; Fitchett, George; Evans, Denis A.; de Leon, Carlos F. Mendes

2013-01-01

Objectives The primary objective of this study was to examine an African American ‘faith advantage’ in life satisfaction. Specifically, we sought to test the hypothesis that the positive relationship between spiritual experiences and life satisfaction is stronger among older African Americans than among older Whites. Method The data came from 6,864 community-dwelling persons aged 65+ (66% African American) who participated in the Chicago Health and Aging Project. Life satisfaction was measured using a five-item composite and we used a five-item version of the Daily Spiritual Experiences scale. Results In a regression model adjusting for age, sex, marital status, education, income, and worship attendance, we found that African American race was associated with lower life satisfaction. We also found a positive association between spiritual experiences and life satisfaction. In an additional model, a significant race × spiritual experiences interaction term indicates that spiritual experiences are more positively associated with life satisfaction among African Americans. Conclusion The data suggest that at higher levels of spiritual experiences, racial differences in life satisfaction are virtually non-existent. However, at lower levels of spiritual experiences, older African Americans show modestly lower levels of life satisfaction than do older Whites. This pattern suggests that spiritual experiences are a positive resource - distinct from worship attendance- that enable older African Americans to overcome decrements in life satisfaction and in fact, that lower spiritual experiences may be especially harmful for older African American’s life satisfaction.

Race and region have independent and synergistic effects on dietary intakes in black and white women

PubMed Central

2012-01-01

Background Few studies have examined the effects of race and region on dietary intakes and the evidence on racial and regional disparities among women is limited. We aimed to examine whether race and region were associated with nutrient intakes among black and white women living in the Stroke Belt, Stroke Buckle, and Other regions in the United States. We hypothesized that significant differences would be observed among population sub-groups and that the effects of race on dietary intakes would vary across regions. Methods This study included dietary data from 12,105 women from the Reasons for Geographic and Racial Differences in Stroke study (United States). Dietary data were collected using the Block 98 food frequency questionnaire. Results Blacks consumed 1.05% lower energy from saturated fat (95% CI: -0.95, -1.16), and intakes were also lower in the Buckle (β = -0.20; 95% CI: -0.08, -0.32) and Belt (β = -0.35; 95% CI: -0.24, -0.46) compared to the Other regions. Within each region, sodium, potassium, and magnesium intakes were all lower among black women compared to white women (P <0.05 for all); intakes were significantly lower among blacks living in the Belt and Buckle compared to those in the Other regions. Significant interactions between race and region were detected for trans fat, calcium, and cholesterol (P <0.05 for all), where black women in the Other regions consumed the lowest dietary cholesterol and calcium while black women in the Belt consumed the lowest trans fat. Conclusions Race and region were significantly associated with nutrient intakes in a large study of black and non-Hispanic white women in the United States. Intakes of trans fat, calcium, and cholesterol among black and white women differed across regions. Race and region thus interact to impact dietary intakes, and their effects may be mediated by such factors as the broader food environment and food availability as well as food customs and culture.

Participants had CPAP use download and completed questionnaires on demographics, sleepiness, insomnia, and social cognitive measures related to adherence. Linear regression modeling was used to explore the impact of measured variables and potential interactions with race-ethnicity on mean daily CPAP use. Results: Participants (N = 248) were 94% male with mean age of 59 ± 11 years and included 95 blacks (38%), 91 whites (37%), and 62 Hispanic (25%) veterans. Blacks had less mean daily CPAP use than whites (-1.6 h, p < 0.001) and Hispanics (-1.3 h, p < 0.01). Blacks reported worse sleep onset insomnia symptoms compared to whites. In the final multivariable regression model, black race-ethnicity (p < 0.01), insomnia symptoms (p < 0.001), and self-efficacy (p < 0.001) were significantly associated with mean daily CPAP use. In addition, the black race by age interaction term showed a trend towards significance (p = 0.10). Conclusions: In agreement with recent studies, we found that mean daily CPAP use in blacks was 1 hour less than whites after adjusting for covariates. No CPAP adherence differences were noted between whites and Hispanics. Further investigations exploring sociocultural barriers to regular CPAP use in minority individuals with OSAHS are needed.

This study investigated race differences in the relationship between formal volunteering and hypertension prevalence among middle-aged and older adults. Using data from the 2004 and 2006 Health and Retirement Study (N = 5,666; 677 African Americans and 4,989 whites), we examined regression models stratified by race to estimate relationships among hypertension prevalence, systolic and diastolic blood pressure, and volunteer status and hours spent volunteering among persons aged 51 years old and older. White volunteers had a lower risk of hypertension than white nonvolunteers. A threshold effect was also present; compared with nonvolunteers, volunteering a moderate number of hours was associated with lowest risk of hypertension for whites. Results for hypertension were consistent with results from alternative models of systolic and diastolic blood pressure. We found no statistically significant relationship between volunteering activity and hypertension/blood pressure for African Americans. There may be unmeasured cultural differences related to the meaning of volunteering and contextual differences in volunteering that account for the race differences we observed. Research is needed to determine the pathways through which volunteering is related to hypertension risk and that may help explain race differences identified here.

Surgical sterilization, regret, and race: contemporary patterns.

PubMed

Shreffler, Karina M; McQuillan, Julia; Greil, Arthur L; Johnson, David R

2015-03-01

Surgical sterilization is a relatively permanent form of contraception that has been disproportionately used by Black, Hispanic, and Native American women in the United States in the past. We use a nationally representative sample of 4592 women ages 25-45 to determine whether sterilization continues to be more common and consequential by race for reproductive-age women. Results indicate that Native American and Black women are more likely to be sterilized than non-Hispanic White women, and Hispanic and Native American women are more likely than non-Hispanic White women to report that their sterilization surgeries prevent them from conceiving children they want. Reasons for sterilization differ significantly by race. These findings suggest that stratified reproduction has not ended in the United States and that the patterns and consequences of sterilization continue to vary by race. Copyright © 2014 Elsevier Inc.

An emerging body of research suggests that depressive symptoms may confer an "accelerated risk" for cardiovascular disease (CVD) in blacks compared with whites. Research in this area has been limited to cardiovascular risk factors and early markers; less is known about black-white differences in associations with important clinical end points. The authors examined the association between depressive symptoms and overall CVD mortality, ischemic heart disease (IHD) mortality, and stroke mortality in a sample of 6158 (62% black; 61% female) community-dwelling older adults. Cox proportional hazards models were used to model time-to-CVD, IHD, and stroke death over a 9- to 12-year follow-up. In race-stratified models adjusted for age and sex, elevated depressive symptoms were associated with CVD mortality in blacks (hazard ratio [HR], 1.95; 95% confidence interval [CI], 1.61 to 2.36; P<0.001) but were not significantly associated with CVD mortality in whites (HR, 1.26; 95% CI, 0.95 to 1.68; P=0.11; race by depressive symptoms interaction, P=0.03). Similar findings were observed for IHD mortality (black: HR, 1.99; 95% CI, 1.49 to 2.64; P<0.001; white: HR, 1.28; 95% CI, 0.86 to 1.89; P=0.23) and stroke mortality (black: HR, 2.08; 95% CI, 1.32 to 3.27; P=0.002; white: HR, 1.32; 95% CI, 0.69 to 2.52; P=0.40). Findings for total CVD mortality and IHD mortality were attenuated but remained significant after adjusting for standard risk factors. Findings for stroke were reduced to marginal significance. Elevated depressive symptoms were associated with multiple indicators of CVD mortality in older blacks but not in whites. Findings were not completely explained by standard risk factors. Efforts aimed at reducing depressive symptoms in blacks may ultimately prove beneficial for their cardiovascular health.

A Quarter Century of Participation in School-Based Extracurricular Activities: Inequalities by Race, Class, Gender and Age?

2018-06-01

Extracurricular activity participation is linked to positive development, but it is also a setting for inequality. Using a quarter century of data from Monitoring the Future (N = 593,979; 51% female; 65% non-Hispanic white; 13% non-Hispanic black; 12% Hispanic; 4% non-Hispanic Asian/Pacific Islander; 7% other race), this article documents patterns and trends in school-based extracurricular participation by race, social class, gender, and age, and their links to academic and substance use outcomes. Findings reveal differences by race and confirm a division by social class that has worsened over time. Further, girls are gaining on boys and surpass them in some types of school-based activities. Participation is linked to better academic outcomes and less substance use, affirming the importance of redressing the inequalities revealed.

Decomposing Black-White Disparities in Heart Disease Mortality in the United States, 1973–2010: An Age-Period-Cohort Analysis

Kramer, Michael R.; Valderrama, Amy L.; Casper, Michele L.

2015-01-01

Against the backdrop of late 20th century declines in heart disease mortality in the United States, race-specific rates diverged because of slower declines among blacks compared with whites. To characterize the temporal dynamics of emerging black-white racial disparities in heart disease mortality, we decomposed race-sex–specific trends in an age-period-cohort (APC) analysis of US mortality data for all diseases of the heart among adults aged ≥35 years from 1973 to 2010. The black-white gap was largest among adults aged 35–59 years (rate ratios ranged from 1.2 to 2.7 for men and from 2.3 to 4.0 for women) and widened with successive birth cohorts, particularly for men. APC model estimates suggested strong independent trends across generations (“cohort effects”) but only modest period changes. Among men, cohort-specific black-white racial differences emerged in the 1920–1960 birth cohorts. The apparent strength of the cohort trends raises questions about life-course inequalities in the social and health environments experienced by blacks and whites which could have affected their biomedical and behavioral risk factors for heart disease. The APC results suggest that the genesis of racial disparities is neither static nor restricted to a single time scale such as age or period, and they support the importance of equity in life-course exposures for reducing racial disparities in heart disease.

Emerging research demonstrates race differences in diurnal cortisol slope, an indicator of hypothalamic-pituitary-adrenocortical (HPA)-axis functioning associated with morbidity and mortality, with African Americans showing flatter diurnal slopes than their White counterparts. Sleep characteristics are associated with both race and with HPA-axis functioning. The present report examines whether sleep duration may account for race differences in cortisol dynamics. Participants were 424 employed African American and White adults (mean age = 42.8 years, 84.2% White, 53.6% female) with no cardiovascular disease (Adult Health and Behavior Project-Phase 2 [AHAB-II] cohort, University of Pittsburgh). Cortisol slope was calculated using 4 salivary cortisol readings, averaged over each of 4 days. Demographic (age, sex), psychosocial (socioeconomic status [SES], affect, discrimination), and health behaviors (smoking, alcohol use, physical activity) variables were used as covariates, and sleep (self-report and accelerometry) was also assessed. African Americans had flatter slopes than Whites (F(1, 411) = 10.45, B = .02, p = .001) in models adjusting for demographic, psychosocial, and health behavior covariates. Shorter actigraphy-assessed total sleep time was a second significant predictor of flatter cortisol slopes (F(1, 411) = 25.27, B = -.0002, p < .0001). Total sleep time partially accounted for the relationship between race and diurnal slope [confidence interval = .05 (lower = .014, upper .04)]. African Americans have flatter diurnal cortisol slopes than their White counterparts, an effect that may be partially attributable to race differences in nightly sleep duration. Sleep parameters should be considered in further research on race and cortisol. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Ischemic stroke accounts for 70% to 80% of all strokes, but intracerebral and subarachnoid hemorrhagic strokes have greater fatality. Age-standardized death rates from overall stroke are higher among men than women, but little is known about sex differences in stroke subtype mortality by race/ethnicity. We analyzed 1995 to 1998 national death certificate data to compare sex-specific age-standardized death rates (per 100 000) for ischemic stroke (n=507 256), intracerebral hemorrhagic stroke (n=98 709), and subarachnoid hemorrhagic stroke (n=27 334) among whites, blacks, American Indians/Alaska Natives, Asians/Pacific Islanders, and Hispanics. We calculated rate ratios and 95% CIs comparing women with men within age and racial/ethnic groups. Age-specific rates of ischemic and intracerebral hemorrhagic stroke deaths were lower for women than for men aged 25 to 44 and 45 to 64 years but were higher for ischemic stroke among older women, aged > or =65 years. Only among whites did women have higher age-standardized rates of ischemic stroke. Age-standardized death rates for intracerebral hemorrhagic stroke among women were lower than or similar to those among men in all racial/ethnic groups. Women had higher risk of death from subarachnoid hemorrhagic; this sex differential increased with age. The female-to-male mortality ratio differs for stroke subtypes by race/ethnicity and age. A primary public health effort should focus on increasing the awareness of stroke symptoms, particularly among people at high risk, to decrease delay in early detection and effective stroke treatment.

Millennials (ages 18-35) are now the largest living generation in the US, making it important to understand and characterize the rising trend of colorectal cancer incidence in this population, as well as other younger generations of Americans. Data from the New Jersey State Cancer Registry (n = 181 909) and Surveillance, Epidemiology, and End Results program (n = 448 714) were used to analyze invasive CRC incidence trends from 1979 to 2014. Age, sex, race, ethnicity, subsite, and stage differences between younger adults (20-49) and screening age adults (≥50) in New Jersey (NJ) were examined using chi-square; and, we compared secular trends in NJ to the United States (US). Whites, men, and the youngest adults (ages 20-39) are experiencing greater APCs in rectal cancer incidence. Rates among younger black adults, overall, were consistently higher in both NJ and the US over time. When compared to older adults, younger adults with CRC in NJ were more likely to be: diagnosed at the late stage, diagnosed with rectal cancer, male, non-white, and Hispanic. Invasive CRC incidence trends among younger adults were found to vary by age, sex, race, ethnicity, and subsite. Large, case-level, studies are needed to understand the role of genetics, human papillomavirus (HPV), and cultural and behavioral factors in the rise of CRC among younger adults. Provider and public education about CRC risk factors will also be important for preventing and reversing the increasing CRC trend in younger adults. © 2018 The Authors.

Understanding state/territorial trends in obesity by race/ethnicity helps focus resources on populations at risk. This study aimed to examine trends in obesity prevalence among low-income, preschool-aged children from 2008 through 2011 in U.S. states and territories by race/ethnicity. We used measured weight and height records of 11.1 million children aged 2-4 years who participated in federally funded health and nutrition programmes in 40 states, the District of Columbia and two U.S. territories. We used logistic regression to examine obesity prevalence trends, controlling for age and sex. From 2008 through 2011, the aggregated obesity prevalence declined among all racial/ethnic groups (decreased by 0.4-0.9%) except American Indians/Alaska Natives (AI/ANs); the largest decrease was among Asians/Pacific Islanders (A/PIs). Declines were significant among non-Hispanic whites in 14 states, non-Hispanic blacks in seven states/territories, Hispanics in 13 states, A/PIs in five states and AI/ANs in one state. Increases were significant among non-Hispanic whites in four states, non-Hispanic blacks in three states, Hispanics in two states and A/PIs in one state. The majority of the states/territories had no change in obesity prevalence. Our findings indicate slight reductions in obesity prevalence and variations in obesity trends, but disparities exist for some states and racial/ethnic groups. © 2015 World Obesity.

Supportive relationships with adults at school are critical to student engagement in adolescence. Additional research is needed to understand how students' racial backgrounds interact with the school context to shape their perceptions of school support. This study employed multilevel, latent variable methods with a sample of Black and White students (N = 19,726, 35.8 % Black, 49.9 % male, mean age = 15.9) in 58 high schools to explore variation in perceived caring, equity, and high expectations by student race, school diversity, and socioeconomic context. The results indicated that Black students perceived less caring and equity relative to White students overall, and that equity and high expectations were lower in diverse schools for both Black and White students. Nonetheless, racial disparities were attenuated in more diverse schools. The findings point to the need for intervention to improve perceptions of school support for Black youth and for all students in lower income and more diverse schools.

Interpersonal psychotherapy (IPT) prevents weight gain and reduces loss-of-control (LOC)-eating in adults. However, IPT was not superior to health-education (HE) for preventing excess weight gain and reducing LOC-eating over 1-year in adolescent girls at risk for excess weight gain and eating disorders. Limited data suggest that older and non-White youth may be especially responsive to IPT. In secondary analyses, we examined if age or race moderated weight and LOC-eating outcomes. The 113 participants (12-17 years; 56.6% White) from the original trial were re-contacted 3 years later for assessment. At baseline and follow-up visits through 3 years, we assessed BMI, adiposity by dual energy X-ray absorptiometry, and LOC-eating presence. In linear mixed models, baseline age moderated 3-year BMI outcome; older girls in IPT had the lowest 3-year BMI gain compared to younger girls in IPT and all girls in HE, p = 0.04. A similar pattern was observed for adiposity. Race moderated 3-year LOC-eating; non-White girls in IPT were most likely to abstain from LOC-eating at 3 years compared to all other girls, p = 0.04. This hypothesis-generating analysis suggests future studies should determine if IPT is especially efficacious at reducing LOC-eating in older, non-White adolescents.

2010-01-01

We used data from the National Longitudinal Study of Adolescent Health to examine transitions among alcohol use classes in 2225 White and African American adolescent girls, and race differences in predictors of transition into and out of problematic drinking classes. Latent class analysis confirmed four classes for White girls and three for AA girls, defined in a previous study. Latent transition analysis revealed more stable abstainers and decreasing alcohol use among AA girls, and more increasing alcohol use among White girls, though stable abstainers were the largest group among both races. Increasing use was predicted by delinquency, academic misbehavior, substance use, and peer support for White girls, and by older age and delinquency for AA girls. Decreasing use was predicted by older age and depressive symptoms for White girls, and by family relationship quality and substance use for AA girls. Study limitations and implications of findings are discussed. PMID:20708254

The intersection of race and gender may create unique experiences for Black and White women in terms of work, family, domestic roles, and interpersonal relationships. Dissimilar gender-role norms may foster different perceptions of gender for these two groups of women. In the current study, we examined similarities and differences in Black and White women's perceptions of their gender using qualitative focus group methodology and grounded theory data analysis. The results identified five themes that were common to Black and White women: Gender-Based Mistreatment, Perceived Advantage, Friendships and Community, Caretaking, and Work and Family Options. One additional theme, Inner Strength, emerged only for Black women. Although many of the broad perceptions of womanhood were similar for Black and White women, analysis of the content within each theme highlighted important differences. We discuss the results in terms of how they may reflect socio-historical factors, gender discrimination, stereotypes, and gender-role norms.

Elevated rate of age-related decline in white matter integrity, indexed by fractional anisotropy (FA) from diffusion tensor imaging, was reported in patients with schizophrenia. Its etiology is unknown. We hypothesized that a decline of blood perfusion to the white matter may underlie the accelerated age-related reduction in FA in schizophrenia. Resting white matter perfusion and FA were collected using pseudo-continuous arterial spin labeling and high-angular-resolution diffusion tensor imaging, respectively, in 50 schizophrenia patients and 70 controls (age=18-63 years). Main outcome measures were the diagnosis-by-age interaction on whole-brain white matter perfusion, and FA. Significant age-related decline in brain white matter perfusion and FA were present in both groups. Age-by-diagnosis interaction was significant for FA (p<0.001) but not white matter perfusion. Age-by-diagnosis interaction for FA values remained significant even after accounting for age-related decline in perfusion. Therefore, we replicated the finding of an increased rate of age-related white matter FA decline in schizophrenia, and observed a significant age-related decline in white matter blood perfusion, although the latter did not contribute to the accelerated age-related decline in FA. The results suggest that factors other than reduced perfusion account for the accelerated age-related decline in white matter integrity in schizophrenia. PMID:24680326

Stroke mortality rates and prevalence of several chronic diseases are higher in Southern populations and blacks in the US. This study examined the relationships of race (black, white) and region (Stroke Belt, Stroke Buckle, other) with selected nutrient intakes among black and white American men (n = 9229). The Block 98 FFQ assessed dietary intakes and multivariable linear regression analysis was used to examine whether race and region were associated with intakes of fiber, saturated fat, trans fat, sodium, potassium, magnesium, calcium, and cholesterol. Race and region were significant predictors of most nutrient intakes. Black men consumed 1.00% lower energy from saturated fat compared with white men [multivariable-adjusted β: 1.00% (95% CI = −0.88, −1.13)]. A significant interaction between race and region was detected for trans fat (P < 0.0001), where intake was significantly lower among black men compared with white men only in the Stroke Belt [multivariable-adjusted β: −0.21 (95% CI = −0.11, −0.31)]. Among black men, intakes of sodium, potassium, magnesium, and calcium were lower, whereas cholesterol was higher, compared with white men (P < 0.05 for all). Comparing regions, men in the Stroke Buckle had the lowest intakes of fiber, potassium, magnesium, and calcium compared with those in the Stroke Belt and other regions; men in both the Stroke Buckle and Stroke Belt had higher intakes of cholesterol compared with those in other regions (P < 0.005 for all). Given these observed differences in dietary intakes, more research is needed to understand if and how they play a role in the health disparities and chronic disease risks observed among racial groups and regions in the US.

Factors at birth and infancy may increase risk of being overweight in childhood. The aim of this study was to examine the relationship of birth size and infant growth (2-24 months) with BMI at age 5 years in a multiethnic population. This was a retrospective study (using electronic medical records of a health maintenance organization in Hawaii) of singleton children born in 2004-2005, with linked maternal and birth information, infant weights (n = 597) and lengths (n = 473) in the first 2 years, and BMI measures at age 5 years (n = 894). Multiple regression models were used to estimate the association of BMI at age 5 years with birth size and infant growth. Birth weight was positively associated with BMI at age 5 years, adjusting for gestational age, sex, race/ethnicity, and maternal prepregnancy weight, age, education, and smoking. A greater change in infant weight was associated with a higher BMI at age 5 years, though the effect of birth weight on BMI was neither mediated nor modified by infant growth rate. Birth weight, change in infant weight, and BMI at age 5 years varied by race/ethnicity. Change in infant BMI in the first 2 years was higher in other Pacific Islanders and whites (Δ = 0.966; confidence interval [CI] = 0.249-1.684; p = 0.02) than in Asian, other, and part Native Hawaiian race/ethnic groups. Early biological measures of birth weight and infant weight gain varied by race/ethnicity and positively predicted BMI at age 5 years.

Coronary artery calcium (CAC) has been demonstrated to independently predict the risk of cardiovascular events and all-cause mortality, especially among White populations. Although the population distribution of CAC has been determined for several White populations, the distribution in ethnically admixed groups has not been well established. The CAC distribution, stratified for age, gender and race, is similar to the previously described distribution in the MESA study. The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) is a prospective cohort study designed to investigate subclinical cardiovascular disease in 6 different centers of Brazil. Similar to previous studies, individuals with self-reported coronary or cerebrovascular disease and those treated for diabetes mellitus were excluded from analysis. Percentiles of CAC distribution were estimated with nonparametric techniques. The analysis included 3616 individuals (54% female; mean age, 50 years). As expected, CAC prevalence and burden were steadily higher with increasing age, as well as increased in men and in White individuals. Our results revealed that for a given CAC score, the ELSA-derived CAC percentile would be lower in men compared with the Multi-Ethnic Study of Atherosclerosis (MESA) and would be higher in women compared with MESA. In our sample of the Brazilian population, we observed significant differences in CAC by sex, age, and race. Adjusted for age and sex, low-risk individuals from the Brazilian population present with significantly lower CAC prevalence and burden compared with other low-risk individuals from other worldwide populations. Using US-derived percentiles in Brazilian individuals may lead to overestimating relative CAC burden in men and underestimating relative CAC burden in women. © 2016 Wiley Periodicals, Inc.

The two worlds of race revisited: a meditation on race in the age of Obama.

PubMed

Early, Gerald

2011-01-01

Nearly fifty years ago, the American Academy organized a conference and two issues of its journal "Daedalus" on the topic of "The Negro American." The project engaged top intellectuals and policy-makers around the conflicts and limitations of mid-1960s liberalism in dealing with race. Specifically, they grappled with the persistent question of how to integrate a forced-worker population that had been needed but that was socially undesirable once its original purpose no longer existed. Today, racism has been discredited as an idea and legally sanctioned segregation belongs to the past, yet the question the conference participants explored -- in essence, how to make the unwanted wanted -- still remains. Recent political developments and anticipated demographic shifts, however, have recast the terms of the debate. Gerald Early, guest editor for the present volume, uses Barack Obama's election to the presidency as a pretext for returning to the central question of "The Negro American" project and, in turn, asking how white liberalism will fare in the context of a growing minority population in the United States. Placing his observations alongside those made by John Hope Franklin in 1965, Early positions his essay, and this issue overall, as a meditation on how far we have come in America to reach "the age of Obama" and at the same time how far we have to go before we can overcome "the two worlds of race."

The effect of age on the racing speed of Thoroughbred racehorses

TAKAHASHI, Toshiyuki

2015-01-01

ABSTRACT The running performance of Thoroughbred racehorses has been reported to peak when they are between 4 and 5 years old. However, changes in their racing speed by month or season have not been reported. The purposes of this study were to reveal the average racing speed of Thoroughbreds, and observe changes in their average speed with age. The surveyed races were flat races on turf and dirt tracks with firm or standard track conditions held by the Japan Racing Association from January 1st, 2002 to December 31st, 2010. The racing speed of each horse was calculated by dividing the race distance (m) by the horse’s final time (sec). Average speeds per month for each age and distance condition were calculated for each gender group when there were 30 or more starters per month for each age and distance condition for each gender group. The common characteristic change for all conditions was an average speed increase up until the first half of the age of 4 years old. The effect of increased carry weight on average speed was small, and average speed increased with the growth of the horse. After the latter half of the age of 4 years old, the horses’ average speed remained almost constant, with little variation. It is speculated that decreases in the weight carried; and the retirement of less well performing horses; are responsible for the maintenance of average speed. PMID:26170760

To determine whether risk factors associated with grade 2-4 intraventricular hemorrhage (IVH) differs between infants of African ancestry and white infants. Inborn, appropriate for gestational age infants with birth weight 500-1250 g and exposure to at least 1 dose of antenatal steroids were enrolled in 24 neonatal intensive care units. Cases had grade 2-4 IVH and controls matched for site, race, and birth weight range had 2 normal ultrasounds read centrally. Multivariate logistic regression modeling identified factors associated with IVH across African ancestry and white race. Subjects included 579 African ancestry or white race infants with grade 2-4 IVH and 532 controls. Mothers of African ancestry children were less educated, and white case mothers were more likely to have more than 1 prenatal visit and multiple gestation (P ≤ .01 for all). Increasing gestational age (P = .01), preeclampsia (P < .001), complete antenatal steroid exposure (P = .02), cesarean delivery (P < .001), and white race (P = .01) were associated with decreased risk for IVH. Chorioamnionitis (P = .01), 5-minute Apgar score <3 (P < .004), surfactant use (P < .001), and high-frequency ventilation (P < .001) were associated with increased risk for IVH. Among African ancestry infants, having more than 1 prenatal visit was associated with decreased risk (P = .02). Among white infants, multiple gestation was associated with increased risk (P < .001), and higher maternal education was associated with decreased risk (P < .05). The risk for IVH differs between infants of African ancestry and white infants, possibly attributable to both race and health care disparities. Copyright © 2014 Elsevier Inc. All rights reserved.

Inflammation as a Mediator of the Association Between Race and Atrial Fibrillation: Results from the Health, Aging, and Body Composition Study

Background Despite a lower prevalence of established atrial fibrillation (AF) risk factors, Whites exhibit substantially higher rates of this arrhythmia compared to Blacks. The mechanism underlying this observation is not known. Both inflammation and obesity are risk factors for AF, and adipose tissue is a known contributor to systemic inflammation. Objectives We sought to determine the degree to which racial differences in AF risk are explained by differences in inflammation and adiposity. Methods Baseline serum inflammatory biomarker concentrations and abdominal adiposity (assessed by computed tomography) were quantified in a subset of Black and White participants without prevalent AF in the Health, Aging, and Body Composition (Health ABC) Study. Participants were prospectively followed for the diagnosis of AF using study ECGs and Medicare claims data. Cox proportional hazards models were used to determine the adjusted relative hazard of incident AF between races before and after biomarker adjustment. Results Among 2,768 participants (43% Black), 721 developed incident AF over a median follow up of 10.9 years. White race was associated with a heightened adjusted risk of incident AF (HR 1.55, 95% CI 1.30 to 1.84, p < 0.001). Abdominal adiposity was not associated with AF when added to the adjusted model. Among the studied biomarkers, adiponectin, TNF-α, TNF-α SR I, and TNF-α SR II concentrations were each higher among Whites and independently associated with a greater risk of incident AF. Together, these inflammatory cytokines mediated 42% (95% CI 15 to 119%, p = 0.004) of the adjusted race-AF association. Conclusions Systemic inflammatory pathways significantly mediate the heightened risk of AF among Whites. The higher level of systemic inflammation and concomitant increased AF risk in Whites is not explained by racial differences in abdominal adiposity or the presence of other pro-inflammatory cardiovascular comorbidities.

Background Race and ethnicity, typically defined as how individuals self-identify, are complex social constructs. Self-identified racial/ethnic minorities are less likely to receive preventive care and more likely to report healthcare discrimination than self-identified non-Hispanic whites. However, beyond self-identification, these outcomes may vary depending on whether racial/ethnic minorities are perceived by others as being minority or white; this perception is referred to as socially-assigned race. Purpose To examine the associations between socially-assigned race and healthcare discrimination and receipt of selected preventive services. Methods Cross-sectional analysis of the 2004 Behavioral Risk Factor Surveillance System “Reactions to Race” module. Respondents from seven states and the District of Columbia were categorized into 3 groups, defined by a composite of self-identified race/socially-assigned race: Minority/Minority (M/M, n = 6,837), Minority/White (M/W, n = 929), and White/White (W/W, n = 25,913). Respondents were 18 years or older, with 61.7% under age 60; 51.8% of respondents were female. Measures included reported healthcare discrimination and receipt of vaccinations and cancer screenings. Results Racial/ethnic minorities who reported being socially-assigned as minority (M/M) were more likely to report healthcare discrimination compared with those who reported being socially-assigned as white (M/W) (8.9% vs. 5.0%, p = 0.002). Those reporting being socially-assigned as white (M/W and W/W) had similar rates for past-year influenza (73.1% vs. 74.3%) and pneumococcal (69.3% vs. 58.6%) vaccinations; however, rates were significantly lower among M/M respondents (56.2% and 47.6%, respectively, p-values<0.05). There were no significant differences between the M/M and M/W groups in the receipt of cancer screenings. Conclusions Racial/ethnic minorities who reported being socially-assigned as white are more likely to receive preventive

The relation between race-related implicit associations and scalp-recorded neural activity evoked by faces from different races.

The neural correlates of the perception of faces from different races were investigated. White participants performed a gender identification task in which Asian, Black, and White faces were presented while event-related potentials (ERPs) were recorded. Participants also completed an implicit association task for Black (IAT-Black) and Asian (IAT-Asian) faces. ERPs evoked by Black and White faces differed, with Black faces evoking a larger positive ERP that peaked at 168 ms over the frontal scalp, and White faces evoking a larger negative ERP that peaked at 244 ms. These Black/White ERP differences significantly correlated with participants' scores on the IAT-Black. ERPs also differentiated White from Asian faces and a significant correlation was obtained between the White-Asian ERP difference waves at approximately 500 ms and the IAT-Asian. A positive ERP at 116 ms over occipital scalp differentiated all three races, but was not correlated with either IAT. In addition, a late positive component (around 592 ms) was greater for the same race compared to either other race faces, suggesting potentially more extended or deeper processing of the same race faces. Taken together, the ERP/IAT correlations observed for both other races indicate the influence of a race-sensitive evaluative process that may include early more automatic and/or implicit processes and relatively later more controlled processes.

The intersection of race and gender may create unique experiences for Black and White women in terms of work, family, domestic roles, and interpersonal relationships. Dissimilar gender-role norms may foster different perceptions of gender for these two groups of women. In the current study, we examined similarities and differences in Black and White women’s perceptions of their gender using qualitative focus group methodology and grounded theory data analysis. The results identified five themes that were common to Black and White women: Gender-Based Mistreatment, Perceived Advantage, Friendships and Community, Caretaking, and Work and Family Options. One additional theme, Inner Strength, emerged only for Black women. Although many of the broad perceptions of womanhood were similar for Black and White women, analysis of the content within each theme highlighted important differences. We discuss the results in terms of how they may reflect socio-historical factors, gender discrimination, stereotypes, and gender-role norms. PMID:29129954

Family identity: black-white interracial family health experience.

The purpose of this interpretive descriptive study was to describe how eight Black-White couples with school-aged children constructed their interracial family identity through developmental transitions and interpreted race to their children. Within and across-case data analytic strategies were used to identify commonalities and variations in how Black men and White women in couple relationships formed their family identities over time. Coming together was the core theme described by the Black-White couples as they negotiated the process of forming a family identity. Four major tasks in the construction of interracial family identity emerged: (a) understanding and resolving family of origin chaos and turmoil, (b) transcending Black-White racial history, (c) articulating the interracial family's racial standpoint, and (d) explaining race to biracial children across the developmental stages. The findings guide family nurses in promoting family identity formation as a component of family health within the nurse-family partnership with Black-White mixed-race families.

In July 1872, the steamship Hero underwent quarantine at Sydney’s North Head after a case of smallpox was diagnosed. This article brings together the histories of quarantine, white subjectivity and Pacific mobility through an analysis of the Loganiana newspaper produced by the passengers of the Hero during their confinement. The Loganiana provides a unique insight into the formation of white identities through discussions of race, commerce, science and inter-colonial politics. The case provides an important perspective on a transformative period in Australia’s border history, and also illuminates the tensions accompanying the transition from an older imperial order to political autonomy in the nineteenth-century Pacific.

PURPOSE To detect differences in retinal thickness among patients of different race, gender and age using Stratus OCT™. DESIGN Cross-sectional study. METHODS In a multicenter, university-based study, 126 patients with no history of ocular disease were enrolled (78 diabetics without retinopathy and 48 nondiabetics). Optical coherence tomography measurements were performed using Stratus OCT™. Statistical comparisons of centerpoint foveal thickness and mean foveal thickness were made using generalized estimating equations adjusting for diabetic status, race, age, and gender. RESULTS The study population consisted of 36% males, 39% Caucasians, 33% African Americans, and 28% Hispanics. Mean foveal thickness was 191.6±2.7µm and 194.5±2.7µm for diabetics and nondiabetics, respectively (P=0.49). Mean foveal thickness in males was significantly larger than in females (201.8±2.7µm and 186.9±2.6µm, respectively; P<0.001). Mean foveal thickness was 200.2±2.7µm for Caucasians, 181.0±3.7µm for African Americans, and 194.7±3.9µm for Hispanics. Mean foveal thickness was significantly less for African Americans than Caucasians (P <0.0001) or Hispanics (P=0.005). Centerpoint foveal thickness and mean foveal thickness showed a significant increase with age. CONCLUSIONS There are statistically significant differences in retinal thickness between subjects of different race, gender, and age. When compared to Caucasians and Hispanics, African-American race is a predictor of decreased mean foveal thickness; and male sex (regardless of race) is a significant predictor of increased mean foveal thickness. Mean foveal thickness is similar among diabetics and nondiabetics when data are controlled for age, race, and sex. These results suggest that studies comparing OCT measurements should carefully control for age, race, and gender-based variations in retinal thickness. PMID:20042179

Association of Race Consciousness With the Patient–Physician Relationship, Medication Adherence, and Blood Pressure in Urban Primary Care Patients

PubMed Central

2013-01-01

BACKGROUND Race consciousness (the frequency with which one thinks about his or her own race) is a measure that may be useful in assessing whether racial discrimination negatively impacts blood pressure (BP). However, the relation between race consciousness and BP has yet to be empirically tested, especially within the context of the patient–physician relationship and medication adherence. METHODS Race-stratified generalized estimating equations were used to assess the relationship of race consciousness on BP, measures of the patient–physician relationship, and self-reported medication adherence, controlling for patients being nested within physicians and for patient age and sex. RESULTS The mean age of the patients was 61.3 years, 62% were black, and 65% were women. Black patients were more likely to ever think about race than were white patients (49% vs. 21%; P < 0.001). Race-conscious blacks had significantly higher diastolic BP (79.4 vs. 74.5mm Hg; P = 0.004) and somewhat higher systolic BP (138.8 vs. 134.7mm Hg; P = 0.13) than blacks who were not race conscious. Race-conscious whites were more likely to perceive respect from their physician (57.1% vs. 25.8%; P = 0.01) but had lower medication adherence (62.4% vs. 82.9%; P = 0.05) than whites who were not race-conscious. CONCLUSIONS Among blacks, race consciousness was associated with higher diastolic BP. In contrast, among whites, there was no association between race consciousness and BP, but race consciousness was associated with poor ratings of adherence, despite more favorable ratings of the patient–physician relationship. Future work should explore disparities in race consciousness and its impact on health and health-care disparities. PMID:23864583

Allostatic load (AL) is a cumulative index of physiological dysregulation, which has been shown to predict cardiovascular events and all-cause mortality. On average, African Americans (AA) have higher AL than their White American (WA) counterparts. This study investigated whether differences in discrimination, negative affect-related variables (e.g., experience and expression of anger, depression), and health practices (e.g., exercise, alcohol use, smoking, subjective sleep quality) mediate racial differences in AL. Participants included healthy, AA (n = 76) and WA (n = 100), middle-aged (Mage = 35.2 years) men (n = 98) and women (n = 78). Questionnaires assessed demographics, psychosocial variables, and health practices. Biological data were collected as part of an overnight hospital stay-AL score was composed of 11 biomarkers. The covariates age, gender, and socioeconomic status were held constant in each analysis. Findings showed significant racial differences in AL, such that AA had higher AL than their WA counterparts. Results of serial mediation indicated a pathway whereby racial group was associated with discrimination, which was then associated with increased experience of anger and decreased subjective sleep quality, which were associated with AL (e.g., race → discrimination → experience of anger → subjective sleep quality → AL); in combination, these variables fully mediated the relationship between race and AL (p < .05). These results suggest that discrimination plays an important role in explaining racial differences in an important indictor of early disease through its relationship with negative affect-related factors and health practices.

Gender and the neighborhood location of mixed-race couples.

2013-04-01

Gender asymmetry in mixed-race heterosexual partnerships and marriages is common. For instance, black men marry or partner with white women at a far higher rate than white men marry or partner with black women. This article asks if such gender asymmetries relate to the racial character of the neighborhoods in which households headed by mixed-race couples live. Gendered power imbalances within households generally play into decisions about where to live or where to move (i.e., men typically benefit more than women), and we find the same in mixed-race couple arrangements and residential attainment. Gender interacts with race to produce a measurable race-by-gender effect. Specifically, we report a positive relationship between the percentage white in a neighborhood and the presence of households headed by mixed-race couples with a white male partner. The opposite holds for households headed by white-blacks and white-Latinos if the female partner is white; they are drawn to predominantly nonwhite neighborhoods. The results have implications for investigations of residential location attainment, neighborhood segregation analysis, and mixed-race studies.

Recent studies showed that women were older than men when achieving their fastest marathon race time. These studies, however, investigated a limited sample of athletes. We investigated the age of peak marathon performance in a large sample of female and male marathon finishers by using data from all finishers. We analyzed the age of peak marathon performance in 1-year and 5-year age intervals of 451,637 runners (i.e. 168,702 women and 282,935 men) who finished the ‘New York City Marathon’ between 2006 and 2016, using analysis of variance and non-linear regression analysis. During these 11 years, men were faster and older than women, the participation of women increased disproportionately to that of men resulting in a decrease of the male-to-female ratio, and relatively more women participated in the younger age groups. Most women were in the age group 30-34 years and most men in the age group 40-44 years. The fastest race time was shown at 29.7 years in women and 34.8 years in men in the 1-year age intervals, and in age group 30-34 years in women and 35-39 years in men in the 5-year age intervals. In contrast to existing findings reporting a higher age of peak marathon performance in women compared to men, we found that women achieved their best marathon race time ~5 years earlier in life than men in both 1-year and 5-year age intervals. Female athletes and their coaches should plan to achieve their fastest marathon race time at the age of ~30 years.

Parental monitoring at age 11 and smoking initiation up to age 17 among Blacks and Whites: a prospective investigation.

Parental monitoring has been identified as a predictor of adolescent smoking initiation. However, it is uncertain if the association is uniform across different racial groups. Random samples of low birth-weight and normal birth-weight children were drawn from newborn discharge lists (1983-1985) of two major hospitals in southeast Michigan, one serving an inner city and the other serving suburbs. Assessments occurred at ages 6, 11, and 17 years. Statistical analysis was conducted on children with data on parent monitoring at age 11 and tobacco use at age 17 who had never smoked a cigarette up to age 11 (n = 572). Multiple logistic regression was used to examine the association between parent monitoring and children's smoking initiation. Two-way interactions were tested. The relationship between parent monitoring at age 11 and child smoking initiation from ages 11 to 17 varied by race. Among White children, an increase of 1 point on the parent monitoring scale signaled an 11% reduction in the odds of initiating smoking by age 17. In contrast, parent monitoring was not significantly associated with smoking initiation among Black children. The results suggest a differential influence of parent monitoring on adolescent smoking between White and Black children. Future research would benefit from close attention to parental goals and concerns and to extra-familial factors that shape smoking behavior across racially and socially disparate communities.

Association Between Stressful Life Events and Depression; Intersection of Race and Gender.

Although stressful life events (SLEs) and depression are associated, we do not know if the intersection of race and gender modifies the magnitude of this link. Using a nationally representative sample of adults in the USA, we tested if the association between SLE and major depressive episode (MDE) depends on the intersection of race and gender. Data came from the National Survey of American Life (NSAL), 2003, a cross-sectional survey that enrolled 5899 adults including 5008 Blacks (African-Americans or Caribbean Blacks), and 891 Non-Hispanic Whites. Logistic regression was used for data analysis. Stressful life events (past 30 days) was the independent variable, 12-month MDE was the dependent variable, and age, educational level, marital status, employment, and region of country were controls. In the pooled sample, SLE was associated with MDE above and beyond all covariates, without the SLE × race interaction term being significant. Among men, the SLE × race interaction was significant, suggesting a stronger association between SLE and MDE among White men compared to Black men. Such interaction between SLE × race could not be found among women. The association between SLE and depression may be stronger for White men than Black men; however, this link does not differ between White and Black women. More research is needed to better understand the mechanism behind race by gender variation in the stress-depression link.

The skin color/race and urbanity are structural determinants of health. The relationship between these variables produces structure of social stratification that defines inequalities in the experiences of life and death. Thus, this study describes the characteristics of the mortality indicators by skin color/race according level of urbanity and aggregation to the metropolitan region (MR) of 5565 cities in Brazil, controlling for gender and age. Descriptive study which included the calculation of measures relating to 1,050,546 deaths in the year survey of 2010 by skin color/race White, Black, and Brown according to both sexes, for five age groups and three levels of urbanity of cities in Brazil that were aggregated or not to the MR in the year of study. The risk of death was estimated by calculating premature mortality rate (PMR) at 65 years of age, per 100,000 and age adjusted. The structure of mortality by skin color/race Black and Brown reflects worse levels of health and excessive premature deaths, with worse situation for men. The Whites, especially women, tend to live longer and in better health than other racial groups. The age-adjusted PMR indicates distinct risk of death by skin color/race, this risk was higher in men than in women and in Blacks than in other racial groups of both sexes. There have been precarious levels of health in the urban space and the MR has intensified these inequalities. The research pointed out that the racial inequality in the mortality was characterized by interaction of race with other individual and contextual determinants of health. Those Blacks and Browns are the groups most vulnerable to the iniquities associated with occurrence of death, but these differences in the profile and the risk of death depend on the level of urbanity and aggregation MR of Brazilian cities in 2010.

Connecting race and place: a county-level analysis of White, Black, and Hispanic HIV prevalence, poverty, and level of urbanization.

We evaluated the role of poverty in racial/ethnic disparities in HIV prevalence across levels of urbanization. Using national HIV surveillance data from the year 2009, we constructed negative binomial models, stratified by urbanization, with an outcome of race-specific, county-level HIV prevalence rates and covariates of race/ethnicity, poverty, and other publicly available data. We estimated model-based Black-White and Hispanic-White prevalence rate ratios (PRRs) across levels of urbanization and poverty. We observed racial/ethnic disparities for all strata of urbanization across 1111 included counties. Poverty was associated with HIV prevalence only in major metropolitan counties. At the same level of urbanization, Black-White and Hispanic-White PRRs were not statistically different from 1.0 at high poverty rates (Black-White PRR = 1.0, 95% confidence interval [CI] = 0.4, 2.9; Hispanic-White PRR = 0.4, 95% CI = 0.1, 1.6). In nonurban counties, racial/ethnic disparities remained after we controlled for poverty. The association between HIV prevalence and poverty varies by level of urbanization. HIV prevention interventions should be tailored to this understanding. Reducing racial/ethnic disparities will require multifactorial interventions linking social factors with sexual networks and individual risks.

The objective of the study was to examine the career profile of the average racehorse in order to establish normal values for performance. Records of race performance for a population of 762 horses randomly-selected from the 1972 registrations of the Canadian Standardbred Horse Society were summarized to provide annual statistics for number of races, money won, and times for the mile (race times) over the period 1974 to 1983 inclusive. Results were analyzed to determine the influence of sex, gait, age, and year of the first race. The transformation log (1 + X) was used to achieve normality where necessary. The 95% confidence interval for the mean (mean range) for career total for number of races was 21.8 to 69.6. Of the horses which raced, 30% raced 20 or fewer times, 29% raced more than 100 times. Females raced significantly less often than either males or geldings (p less than 0.001), pacers significantly more often than trotters (p less than 0.01). Regardless of the age at which they first competed all horses were raced lightly in their first race year. Mean range for career total for money won was $2,212 to $2,798 (n = 507). Of 507 horses which raced, 65.8% earned less than $10,000, 6.3% more than $50,000. Trotting geldings had the highest mean money won, mean range $2,448 to $38,105. Mean range for money won per race for all horses racing was $67.77 to $74.51. Overall, 58% of horses earned less than $100 per race, 4.5% over $500. Only 4.5% of horses racing met their immediate training expenses. Increase in age at first race was associated with highly significant and progressive reductions in career races, money won, and money won per race. Of 507 horses which raced, 409 or 80% won at least one race and thus acquired an official winning time or mark. Population mean for career mark was 2.126 min (2.07.3.). Population trend in mean mark was for progressive improvement over the ten year racing period amounting to 0.0968 min or 5.81 s. The average horse achieved

Face memory is worse for races other than one's own, in part because other-race faces are less holistically processed. Both experiential factors and social factors have been suggested as reasons for this other-race effect. Direct measures of holistic processing for race and a non-racial category in faces have never been employed, making it difficult to establish how experience and group membership interact. This study is the first to directly explore holistic processing of own-race and other-race faces, also classed by a non-racial category (university affiliation). Using a crossover design, White undergraduates (in Australia) completed the part-whole task for White (American) and Black South African faces attributed to the University of Western Sydney (own) and University of Sydney (other). Black South African undergraduates completed the same task for White and Black South African faces attributed to the University of Cape Town (own) and Stellenbosch University (other). It was hypothesised that own-race faces would be processed more holistically than other-race faces and that own-university faces would be processed more holistically than other-university faces. Results showed a significant effect of race for White participants (White faces were matched more accurately than Black faces), and wholes were matched more accurately than parts, suggesting holistic processing, but only for White faces. No effect of university was found. Black South African participants, who have more experience with other-race faces, processed wholes better than parts irrespective of race and university category. Overall, results suggest that experiential factors of race outweigh any effects of a non-racial shared group membership. The quality of experience for the named populations, stimuli presentation, and degree of individuation are discussed.

We estimated the effect of the ACA expansion of dependents' coverage on health care expenditures and utilization for young adults by race/ethnicity. We used difference-in-difference models to estimate the impact of the ACA expansion on health care expenditures, out-of-pocket payments (OOP) as a share of total health care expenditure, and utilization among young adults aged 19 to 26 years by race/ethnicity (White, African American, Latino, and other racial/ethnic groups), with adults aged 27 to 30 years as the control group. In 2011 and 2012, White and African American young adults aged 19 to 26 years had significantly lower total health care spending compared with the 27 to 30 years cohort. OOP, as a share of health care expenditure, remained the same after the ACA expansion for all race/ethnicity groups. Changes in utilization following the ACA expansion among all racial/ethnic groups for those aged 19 to 26 years were not significant. Our study showed that the impact of the ACA expansion on health care expenditures differed by race/ethnicity.

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.

Gendered race: are infants' face preferences guided by intersectionality of sex and race?

PubMed

Kim, Hojin I; Johnson, Kerri L; Johnson, Scott P

2015-01-01

People occupy multiple social categories simultaneously (e.g., a White female), and this complex intersectionality affects fundamental aspects of social perception. Here, we examined the possibility that infant face processing may be susceptible to effects of intersectionality of sex and race. Three- and 10-month-old infants were shown a series of computer-generated face pairs (5 s each) that differed according to sex (Female or Male) or race (Asian, Black, or White). All possible combinations of face pairs were tested, and preferences were recorded with an eye tracker. Infants showed preferences for more feminine faces only when they were White, but we found no evidence that White or Asian faces were preferred even though they are relatively more feminized. These findings challenge the notions that infants' social categories are processed independently of one another and that infants' preferences for sex or race can be explained from mere exposure.

2017-03-01

The role of experience with other-race faces in the development of the other-race effect was investigated through a cross-cultural comparison between 5- and 6-year-olds and 13- and 14-year-olds raised in a monoracial (British White, n=83) population and a multiracial (Malaysian Chinese, n=68) population. British White children showed an other-race effect to three other-race faces (Chinese, Malay, and African Black) that was stable across age. Malaysian Chinese children showed a recognition deficit for less experienced faces (African Black) but showed a recognition advantage for faces of which they have direct or indirect experience. Interestingly, younger (Malaysian Chinese) children showed no other-race effect for female faces such that they can recognize all female faces regardless of race. These findings point to the importance of early race and gender experiences in reorganizing the face representation to accommodate changes in experience across development.

Sleep Differences by Race in Preschool Children: The Roles of Parenting Behaviors and Socioeconomic Status.

PubMed

Patrick, Kristina E; Millet, Genevieve; Mindell, Jodi A

2016-01-01

This study aimed to examine whether socioeconomic variables (SES) and parenting behaviors mediate differences in sleep problems between Black and White preschool-aged children. Parents of 191 preschool-aged children (53% male; 77% White) completed questionnaires regarding SES and sleep behaviors. Parenting behaviors and SES were analyzed as mediators of differences in sleep problems between Black and White children. Parent behaviors related to bedtime routine and independence mediated the relationship between race and parent-reported bedtime difficulty, parent confidence managing sleep, and sleep onset latency. SES mediated the relationship between race and sleep onset latency. Sleep differences between Black and White preschool children were primarily mediated by parent behaviors rather than socioeconomic variables. Results may reflect differences in cultural practices and provide important information for treatment and parent-directed intervention regarding improving sleep in young children.

Black client, white therapist: working with race in psychoanalytic psychotherapy in South Africa.

PubMed

Knight, Zelda Gillian

2013-02-01

In post-apartheid South Africa we speak about race extensively. It permeates our workplace, weaves a thread through the fabric of our professional and personal lives, as well as our private conversations and public interactions with others. From within psychoanalytic theory, the thread weaves through the unknown content of our racialized unconscious. When there is a focus on race in the South African psychoanalytic context it largely takes the form of the struggle to articulate the complexities of working with difference, as Swartz notes, or the struggle to map out issues of race. Such struggles are not localized in South Africa, but strongly reflect a much broader struggle within the global psychoanalytic community, as mirrored in the expanding focus on race. Although the consulting rooms seem far removed from the ongoing political tensions that have recently emerged in South Africa, psychoanalytic psychotherapy remains a space of meaningful engagement with the other, and where the therapeutic dyad is one of racial difference it permits an encounter with our racialized unconscious. This article seeks to document the experience of my black client and my white response to her racial pain and struggle; in doing so, I describe the racial 'contact' between us and within us that triggers a racialized transference and countertransference dynamic, which contains the space for racial healing for both of us.

Compared to whites, blacks have higher colorectal cancer incidence and mortality rates and are at greater risk for early-onset disease. The reasons for this racial disparity are poorly understood, but one contributing factor could be differences in access to high-quality screening and medical care. The present study was carried out to assess whether a racial difference in prevalence of large bowel polyps persists within a poor and uninsured population (n = 233, 124 blacks, 91 whites, 18 other) undergoing screening colonoscopy. Eligible patients were uninsured, asymptomatic, had no personal history of colorectal neoplasia, and were between the ages 45-64 years (blacks) or 50-64 years (whites, other). We examined the prevalence of any adenoma (conventional, serrated) and then difference in adenoma/polyp type by race and age categories. Prevalence for ≥1 adenoma was 37 % (95 % CI 31-43 %) for all races combined and 36 % in blacks <50 years, 38 % in blacks ≥50 years, and 35 % in whites. When stratified by race, blacks had a higher prevalence of large conventional proximal neoplasia (8 %) compared to whites (2 %) (p value = 0.06) but a lower prevalence of any serrated-like (blacks 18 %, whites 32 %; p value = 0.02) and sessile serrated adenomas/polyps (blacks 2 %, whites 8 % Chi-square p value; p = 0.05). Within this uninsured population, the overall prevalence of adenomas was high and nearly equal by race, but the racial differences observed between serrated and conventional polyp types emphasize the importance of taking polyp type into account in future research on this topic.

Dental services use is a public health issue that varies by race. African Americans are less likely than whites to make use of these services. While several explanations exist, little is known about the role of segregation in understanding this race difference. Most research does not account for the confounding of race, socioeconomic status, and segregation. Using cross-sectional data from the Exploring Health Disparities in Integrated Communities Study, we examined the relationship between race and dental services use. Our primary outcome of interest was dental services use within 2 years. Our main independent variable was self-identified race. Of the 1408 study participants, 59.3% were African American. More African Americans used dental services within 2 years than whites. After adjusting for age, gender, marital status, income, education, insurance, self-rated health, and number of comorbidities, African Americans had greater odds of having used services (odds ratio = 1.48, 95% confidence interval 1.16, 1.89) within 2 years. Within this low-income racially integrated sample, African Americans participated in dental services more than whites. Place of living is an important factor to consider when seeking to understand race differences in dental service use.

Disconnected Aging: Cerebral White Matter Integrity and Age-Related Differences in Cognition

PubMed Central

Bennett, Ilana J.; Madden, David J.

2013-01-01

Cognition arises as a result of coordinated processing among distributed brain regions and disruptions to communication within these neural networks can result in cognitive dysfunction. Cortical disconnection may thus contribute to the declines in some aspects of cognitive functioning observed in healthy aging. Diffusion tensor imaging (DTI) is ideally suited for the study of cortical disconnection as it provides indices of structural integrity within interconnected neural networks. The current review summarizes results of previous DTI aging research with the aim of identifying consistent patterns of age-related differences in white matter integrity, and of relationships between measures of white matter integrity and behavioral performance as a function of adult age. We outline a number of future directions that will broaden our current understanding of these brain-behavior relationships in aging. Specifically, future research should aim to (1) investigate multiple models of age-brain-behavior relationships; (2) determine the tract-specificity versus global effect of aging on white matter integrity; (3) assess the relative contribution of normal variation in white matter integrity versus white matter lesions to age-related differences in cognition; (4) improve the definition of specific aspects of cognitive functioning related to age-related differences in white matter integrity using information processing tasks; and (5) combine multiple imaging modalities (e.g., resting-state and task-related functional magnetic resonance imaging; fMRI) with DTI to clarify the role of cerebral white matter integrity in cognitive aging.

Implantable cardioverter defibrillator (ICD) therapy improves survival of patients with systolic heart failure. We assessed whether physicians' recommendation for ICD therapy varies as a function of patient age, gender, race, and physician's specialty. We surveyed a random sample (n = 9969) of U.S. physicians who are active members of the American College of Cardiology (ACC). We asked participants about their likelihood to recommend ICD therapy in 4 clinical scenarios that randomly varied patient age, gender, race, and ICD indication (guideline Class I, Class IIa, Class III, and Class I in a noncompliant patient). Responses were received from 1210 physicians (response rate 12%), of whom 1127 met the study inclusion criteria. Responders and nonresponders had similar demographics. In responding to hypothetical clinical scenarios, physicians were less likely to recommend an ICD to older patients (≥80 vs 50 years) (P < 0.01) but were unaffected by gender or race for all class indications. Compared with non-electrophysiologists (EPs), EPs were significantly more likely to recommend an ICD for a Class I indication (92.4% vs 81.4%; P < 0.01), but they were not more likely to offer an ICD for a Class III indication (0.4% vs 0.6%; P = 0.95). Based on survey responses, physicians were equally willing to offer an ICD to men and women and to whites and blacks, but were less likely to offer an ICD to an older patient even when indicated by practice guidelines. Electrophysiologists (EPs) more often adhered to practice guideline recommendations on ICD therapy compared with non-EPs. ©2011, Wiley Periodicals, Inc.

Wu, Li-Tzy; Blazer, Dan G.; Swartz, Marvin S.; Burchett, Bruce; Brady, Kathleen T.

2013-01-01

Background The racial/ethnic composition of the United States is shifting rapidly, with non-Hispanic Asian-Americans, Native Hawaiians/Pacific Islanders (NHs/PIs), and mixed-race individuals the fastest growing segments of the population. We determined new drug use estimates for these rising groups. Prevalences among Whites were included as a comparison. Methods Data were from the 2005–2011 National Surveys on Drug Use and Health. Substance use among respondents aged ≥12 years was assessed by computer-assisted self-interviewing methods. Respondents’ self-reported race/ethnicity, age, gender, household income, government assistance, county type, residential stability, major depressive episode, history of being arrested, tobacco use, and alcohol use were examined as correlates. We stratified the analysis by race/ethnicity and used logistic regression to estimate odds of drug use. Results Prevalence of past-year marijuana use among Whites increased from 10.7% in 2005 to 11.6–11.8% in 2009–2011 (P<0.05). There were no significant yearly changes in drug use prevalences among Asian-Americans, NHs/PIs, and mixed-race people; but use of any drug, especially marijuana, was prevalent among NHs/PIs and mixed-race people (21.2% and 23.3%, respectively, in 2011). Compared with Asian-Americans, NHs/PIs had higher odds of marijuana use, and mixed-race individuals had higher odds of using marijuana, cocaine, hallucinogens, stimulants, sedatives, and tranquilizers. Compared with Whites, mixed-race individuals had greater odds of any drug use, mainly marijuana, and NHs/PIs resembled Whites in odds of any drug use. Conclusions Findings reveal alarmingly prevalent drug use among NHs/PIs and mixed-race people. Research on drug use is needed in these rising populations to inform prevention and treatment efforts.

Is race medically relevant? A qualitative study of physicians' attitudes about the role of race in treatment decision-making

PubMed Central

2011-01-01

Background The role of patient race in medical decision-making is heavily debated. While some evidence suggests that patient race can be used by physicians to predict disease risk and determine drug therapy, other studies document bias and stereotyping by physicians based on patient race. It is critical, then, to explore physicians' attitudes regarding the medical relevance of patient race. Methods We conducted a qualitative study in the United States using ten focus groups of physicians stratified by self-identified race (black or white) and led by race-concordant moderators. Physicians were presented with a medical vignette about a patient (whose race was unknown) with Type 2 diabetes and untreated hypertension, who was also a current smoker. Participants were first asked to discuss what medical information they would need to treat the patient. Then physicians were asked to explicitly discuss the importance of race to the hypothetical patient's treatment. To identify common themes, codes, key words and physician demographics were compiled into a comprehensive table that allowed for examination of similarities and differences by physician race. Common themes were identified using the software package NVivo (QSR International, v7). Results Forty self-identified black and 50 self-identified white physicians participated in the study. All physicians - regardless of their own race - believed that medical history, family history, and weight were important for making treatment decisions for the patient. However, black and white physicians reported differences in their views about the relevance of race. Several black physicians indicated that patient race is a central factor for choosing treatment options such as aggressive therapies, patient medication and understanding disease risk. Moreover, many black physicians considered patient race important to understand the patient's views, such as alternative medicine preferences and cultural beliefs about illness. However

Objectives. We estimated the effect of the ACA expansion of dependents’ coverage on health care expenditures and utilization for young adults by race/ethnicity. Methods. We used difference-in-difference models to estimate the impact of the ACA expansion on health care expenditures, out-of-pocket payments (OOP) as a share of total health care expenditure, and utilization among young adults aged 19 to 26 years by race/ethnicity (White, African American, Latino, and other racial/ethnic groups), with adults aged 27 to 30 years as the control group. Results. In 2011 and 2012, White and African American young adults aged 19 to 26 years had significantly lower total health care spending compared with the 27 to 30 years cohort. OOP, as a share of health care expenditure, remained the same after the ACA expansion for all race/ethnicity groups. Changes in utilization following the ACA expansion among all racial/ethnic groups for those aged 19 to 26 years were not significant. Conclusions. Our study showed that the impact of the ACA expansion on health care expenditures differed by race/ethnicity. PMID:25905850

Racializing white drag.

PubMed

Rhyne, Ragan

2004-01-01

While drag is primarily understood as a performance of gender, other performative categories such as race, class, and sexuality create drag meaning as well. Though other categories of identification are increasingly understood as essential elements of drag by performers of color, whiteness remains an unmarked category in the scholarship on drag performances by white queens. In this paper, I argue that drag by white queens must be understood as a performance of race as well as gender and that codes of gender excess are specifically constructed through the framework of these other axes of identity. This essay asks whether white performance by white queens necessarily reinscribes white supremacy through the performance of an unmarked white femininity, or might drag performance complicate (though not necessarily subvert) categories of race as well as gender? In this essay, I will suggest that camp drag performances, through the deployment of class as a crucial category of performative femininity, might indeed be a key site through which whiteness is denaturalized and its power challenged. Specifically, I will read on camp as a politicized mode of race, class and gender performance, focusing on the intersections of these categories of identity in the drag performance of Divine.

Interpretation of longitudinal information about lung function decline from middle to older age has been limited by loss to follow-up that may be correlated with baseline lung function or the rate of decline. We conducted these analyses to estimate age-related decline in lung function across groups of race, sex, and smoking status while accounting for dropout from the Atherosclerosis Risk in Communities Study. We analyzed data from 13,896 black and white participants, aged 45-64 years at the 1987-1989 baseline clinical examination. Using spirometry data collected at baseline and two follow-up visits, we estimated annual population-averaged mean changes in forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) by race, sex, and smoking status using inverse-probability-weighted independence estimating equations conditioning-on-being-alive. Estimated rates of FEV1 decline estimated using inverse-probability-weighted independence estimating equations conditioning on being alive were higher among white than black participants at age 45 years (e.g., male never smokers: black: -29.5 ml/year; white: -51.9 ml/year), but higher among black than white participants by age 75 (black: -51.2 ml/year; white: -26). Observed differences by race were more pronounced among men than among women. By smoking status, FEV1 declines were larger among current than former or never smokers at age 45 across all categories of race and sex. By age 60, FEV1 decline was larger among former and never than current smokers. Estimated annual declines generated using unweighted generalized estimating equations were smaller for current smokers at younger ages in all four groups of race and sex compared with results from weighted analyses that accounted for attrition. Using methods accounting for dropout from an approximately 25-year health study, estimated rates of lung function decline varied by age, race, sex, and smoking status, with largest declines observed among current

Paternal Race/Ethnicity and Birth Outcomes

PubMed Central

2008-01-01

Objectives. I sought to identify whether there were associations between paternal race/ethnicity and birth outcomes among infants with parents of same- and mixed-races/ethnicities. Methods. Using the National Center for Health Statistics 2001 linked birth and infant death file, I compared birth outcomes of infants of White mothers and fathers of different races/ethnicities by matching and weighting racial/ethnic groups following a propensity scoring approach so other characteristics were distributed identically. I applied the same analysis to infants of Black parents and infants with a Black mother and White father. Results. Variation in risk factors and outcomes was found in infants of White mothers by paternal race/ethnicity. After propensity score weighting, the disparities in outcomes by paternal or parental race/ethnicity could be largely attributed to nonracial parental characteristics. Infants whose paternal race/ethnicity was unreported on their birth certificates had the worst outcomes. Conclusions. The use of maternal race/ethnicity to refer to infant race/ethnicity in research is problematic. The effects of maternal race/ethnicity on birth outcomes are estimated to be much larger than that of paternal race/ethnicity after I controlled for all covariates. Not listing a father on the birth certificate had a strong association with outcomes, which might be a source of bias in existing data and a marker for identifying infants at risk. PMID:18445802

Disconnected aging: cerebral white matter integrity and age-related differences in cognition.

PubMed

Bennett, I J; Madden, D J

2014-09-12

Cognition arises as a result of coordinated processing among distributed brain regions and disruptions to communication within these neural networks can result in cognitive dysfunction. Cortical disconnection may thus contribute to the declines in some aspects of cognitive functioning observed in healthy aging. Diffusion tensor imaging (DTI) is ideally suited for the study of cortical disconnection as it provides indices of structural integrity within interconnected neural networks. The current review summarizes results of previous DTI aging research with the aim of identifying consistent patterns of age-related differences in white matter integrity, and of relationships between measures of white matter integrity and behavioral performance as a function of adult age. We outline a number of future directions that will broaden our current understanding of these brain-behavior relationships in aging. Specifically, future research should aim to (1) investigate multiple models of age-brain-behavior relationships; (2) determine the tract-specificity versus global effect of aging on white matter integrity; (3) assess the relative contribution of normal variation in white matter integrity versus white matter lesions to age-related differences in cognition; (4) improve the definition of specific aspects of cognitive functioning related to age-related differences in white matter integrity using information processing tasks; and (5) combine multiple imaging modalities (e.g., resting-state and task-related functional magnetic resonance imaging; fMRI) with DTI to clarify the role of cerebral white matter integrity in cognitive aging.

Age, sex and (the) race: gender and geriatrics in the ultra-endurance age.

PubMed

Whyte, Greg

2014-01-01

Ultra-endurance challenges were once the stuff of legend isolated to the daring few who were driven to take on some of the greatest physical endurance challenges on the planet. With a growing fascination for major physical challenges during the nineteenth century, the end of the Victorian era witnessed probably the greatest ultra-endurance race of all time; Scott and Amundsen's ill-fated race to the South Pole. Ultra-endurance races continued through the twentieth century; however, these events were isolated to the elite few. In the twenty-first century, mass participation ultra-endurance races have grown in popularity. Endurance races once believed to be at the limit of human durability, i.e. marathon running, are now viewed as middle-distance races with the accolade of true endurance going to those willing to travel significantly further in a single effort or over multiple days. The recent series of papers in Extreme Physiology & Medicine highlights the burgeoning research data from mass participation ultra-endurance events. In support of a true 'mass participation' ethos Knetchtle et al. reported age-related changes in Triple and Deca Iron-ultra-triathlon with an upper age of 69 years! Unlike their shorter siblings, the ultra-endurance races appear to present larger gender differences in the region of 20% to 30% across distance and modality. It would appear that these gender differences remain for multi-day events including the 'Marathon des Sables'; however, this gap may be narrower in some events, particularly those that require less load bearing (i.e. swimming and cycling), as evidenced from the 'Ultraman Hawaii' and 'Swiss Cycling Marathon', and shorter (a term I used advisedly!) distances including the Ironman Triathlon where differences are similar to those of sprint and endurance distances i.e. c. 10%. The theme running through this series of papers is a continual rise in participation to the point where major events now require selection races to remain

To evaluate a modified Finnish Diabetes Risk Score (FINDRISC) for predicting the risk of incident diabetes among white and black middle-aged participants from the Atherosclerosis Risk in Communities (ARIC) study. We assessed 9754 ARIC cohort participants who were free of diabetes at baseline. Logistic regression and receiver operator characteristic (ROC) curves were used to evaluate a modified FINDRISC for predicting incident diabetes after 9 years of follow-up, overall and by race/gender group. The modified FINDRISC used comprised age, body mass index, waist circumference, blood pressure medication and family history. The mean FINDRISC (range, 2 [lowest risk] to 17 [highest risk]) for black women was higher (9.9 ± 3.6) than that for black men (7.6 ± 3.9), white women (8.0 ± 3.6) and white men (7.6 ± 3.5). The incidence of diabetes increased generally across deciles of FINDRISC for all 4 race/gender groups. ROC curve statistics for the FINDRISC showed the highest area under the curve for white women (0.77) and the lowest for black men (0.70). We used a modified FINDRISC to predict the 9-year risk of incident diabetes in a biracial US population. The modified risk score can be useful for early screening of incident diabetes in biracial populations, which may be helpful for early interventions to delay or prevent diabetes. © 2017 John Wiley & Sons Ltd.

Although black patients with endometrial cancer (EC) have worse survival compared with white patients, the interaction between age/race has not been examined. The primary objective was to evaluate the impact of age at diagnosis on racial disparities in disease presentation and outcome in EC. We evaluated women diagnosed with EC between 1991 and 2010 from the Surveillance, Epidemiology, and End Results. Mutation status for TP53 or PTEN, or with the aggressive integrative, transcript-based, or somatic copy number alteration-based molecular subtype were acquired from the Cancer Genome Atlas. Logistic regression model was used to estimate the interaction between age and race on histology. Cox regression model was used to estimate the interaction between age and race on survival. 78,184 white and 8518 black patients with EC were analyzed. Median age at diagnosis was 3-years younger for black vs. white patients with serous cancer and carcinosarcoma (P<0.0001). The increased presentation of non-endometrioid histology with age was larger in black vs. white patients (P<0.0001). The racial disparity in survival and cancer-related mortality was more prevalent in black vs. white patients, and in younger vs. older patients (P<0.0001). Mutations in TP53, PTEN and the three aggressive molecular subtypes each varied by race, age and histology. Aggressive histology and molecular features were more common in black patients and older age, with greater impact of age on poor tumor characteristics in black vs. white patients. Racial disparities in outcome were larger in younger patients. Intervention at early ages may mitigate racial disparities in EC. Copyright © 2017 Elsevier Inc. All rights reserved.

Both HIV disease and advanced age have been associated with alterations to cerebral white matter, as measured with white matter hyperintensities (WMH) on fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI), and more recently with diffusion tensor imaging (DTI). This study investigates the combined effects of age and HIV serostatus on WMH and DTI measures, as well as the relationships between these white matter measures, in 88 HIV seropositive (HIV+) and 49 seronegative (HIV-) individuals aged 23-79 years. A whole-brain volumetric measure of WMH was quantified from FLAIR images using a semi-automated process, while fractional anisotropy (FA) was calculated for 15 regions of a whole-brain white matter skeleton generated using tract-based spatial statistics (TBSS). An age by HIV interaction was found indicating a significant association between WMH and older age in HIV+ participants only. Similarly, significant age by HIV interactions were found indicating stronger associations between older age and decreased FA in the posterior limbs of the internal capsules, cerebral peduncles, and anterior corona radiata in HIV+ vs. HIV- participants. The interactive effects of HIV and age were stronger with respect to whole-brain WMH than for any of the FA measures. Among HIV+ participants, greater WMH and lower anterior corona radiata FA were associated with active hepatitis C virus infection, a history of AIDS, and higher current CD4 cell count. Results indicate that age exacerbates HIV-associated abnormalities of whole-brain WMH and fronto-subcortical white matter integrity.

The sociological literature on workplace inequality has been relatively clear regarding racial disparities and ongoing vulnerabilities to contemporary structural and employer biases. We still know little, however, about the consequences of age and ageism for minority workers and susceptibilities to downward mobility. Coupling insights regarding race with recent work on employment-based age discrimination, we interrogate in this article African Americans and Whites, aged 55 and older, and the extent to which they experience job loss across time. Our analyses, beyond controlling for key background attributes, distinguish and disaggregate patterns for higher and lower level status managers and professionals and for men and women. Results, derived from data from the Panel Study of Income Dynamics, reveal unique and significant inequalities. Relative to their White and gender specific counterparts, older African American men and women experience notably higher rates of downward mobility-downward mobility that is not explained by conventional explanations (i.e., human capital credentials, job/labor market characteristics, etc.). Such inequalities are especially pronounced among men and for those initially occupying higher status white-collar managerial and professional jobs compared to technical/skilled professional and blue-collar "first line" supervisors. We tie our results to contemporary concerns regarding ageism in the workplace as well as minority vulnerability. We also suggest an ageism-centered corrective to existing race and labor market scholarship. Copyright © 2017 Elsevier Inc. All rights reserved.

To examine self-reported weight discrimination and differences based on race, sex, and BMI in a biracial cohort of community-based middle-aged adults. Participants (3,466, mean age = 50 years, mean BMI = 30 kg/m²) of the Coronary Artery Risk Development in Young Adults (CARDIA) Study who completed the 25-year examination of this epidemiological investigation in 2010-2011 were reported. The sample included normal weight, overweight, and obese participants. CARDIA participants are distributed into four race-sex groups, with about half being African-American and half White. Participants completed a self-reported measure of weight discrimination. Among overweight/obese participants, weight discrimination was lowest for White men (12.0%) and highest for White women (30.2%). The adjusted odds ratio (95% CI) for weight discrimination in those with class 2/3 obesity (BMI ≥ 35 kg/m²) versus the normal-weight was most pronounced: African American men, 4.59 (1.71-12.34); African American women, 7.82 (3.57-17.13); White men, 6.99 (2.27-21.49); and White women, 18.60 (8.97-38.54). Being overweight (BMI = 25-29.9 kg/m²) vs. normal weight was associated with increased discrimination in White women only: 2.10 (1.11-3.96). Novel evidence for a race-sex interaction on perceived weight discrimination, with White women more likely to report discrimination at all levels of overweight and obesity was provided. Pychosocial mechanisms responsible for these differences deserve exploration. Copyright © 2013 The Obesity Society.

Older adults are remaining sexually active for longer periods of time, underscoring the need to assess sexual activity patterns in this group and identify differences by race/ethnicity, some of which may have implications for the development and implementation of sexual risk reduction interventions. Using data from the 2010 National Social Life, Health, and Aging Project, this study examined responses from 1,429 adults aged 60 years and older. Multinomial logistic regression compared sexual behaviors, health-related indicators, interactions with healthcare professionals, and HIV-related perceptions across participants' race/ethnicity. Approximately 81% of participants self-reported as non-Hispanic white, 10.59% as African American, and 8.05% as Hispanic. On average, participants were 69.9 years of age. In the previous year, 49.3% of participants engaged in sexual intercourse; only 3% used condoms. The majority of participants (83.1%) visited a physician at least twice in the previous year, 30.9% had discussed sex with a physician since turning 50, and 14.2% had been tested for HIV. Relative to non-Hispanic whites, African Americans were more likely to be divorced (OR=3.23, P<0.001) or widowed (OR=2.90, P<0.001); have more lifetime sexually transmitted infection (STI) diagnoses (OR=1.67, P=0.030); and have paid for sex (OR=2.83, P=0.002). Although African Americans had greater perceived risk for HIV infection (OR=1.66, P=0.046), they were less likely to have discussed sex with a physician since turning 50 (OR=0.45, P=0.009). Contextualized interventions to improve patient-provider communication and proactive screening behaviors in sexually-active and aging African Americans are needed.

Human sex differences in emotional processing of own-race and other-race faces.

There is evidence that women and men show differences in the perception of affective facial expressions. However, none of the previous studies directly investigated sex differences in emotional processing of own-race and other-race faces. The current study addressed this issue using high time resolution event-related potential techniques. In total, data from 25 participants (13 women and 12 men) were analyzed. It was found that women showed increased N170 amplitudes to negative White faces compared with negative Chinese faces over the right hemisphere electrodes. This result suggests that women show enhanced sensitivity to other-race faces showing negative emotions (fear or disgust), which may contribute toward evolution. However, the current data showed that men had increased N170 amplitudes to happy Chinese versus happy White faces over the left hemisphere electrodes, indicating that men show enhanced sensitivity to own-race faces showing positive emotions (happiness). In this respect, men might use past pleasant emotional experiences to boost recognition of own-race faces.

The Food and Drug Administration is in the process of reviewing evidence of the impact of mentholated cigarettes on smoking behaviors and smoking cessation in order to determine if these products should be removed from the market. More empirical research is needed to inform those decisions. The goal of this study was to examine associations of menthol cigarette use with biochemically verified continuous short-term smoking abstinence, and potential moderation by race, among adult current smokers enrolled in a cohort study (N = 183; 57.4% female; 48.1% non-Hispanic Black, 51.9% non-Hispanic White). Continuation ratio logit models, adjusted for age, race, gender, total annual household income, educational level, employment status, and partner status, were used to examine associations of menthol use with smoking abstinence with and without an interaction term for race. Menthol cigarette use was not significantly associated with smoking abstinence in the sample as a whole; however, there was a significant interaction of menthol use with race (p = .03). Follow-up analyses stratified by race indicated that among White participants, menthol users had significantly lower odds of maintaining continuous abstinence than nonmenthol users (p = .05). Exploratory analyses suggested that tobacco dependence may lie along the causal pathway and partially explain this effect. White menthol smokers in this sample were at increased risk of smoking relapse relative to White nonmenthol smokers, at least partially due to greater tobacco dependence. Results should be replicated among other treatment-seeking samples with a greater representation of White menthol and Black nonmenthol smokers.

Acute kidney injury (AKI) is a serious global public health problem. We aimed to quantify the risk of AKI associated with estimated glomerular filtration rate (eGFR), albuminuria (albumin-creatinine ratio [ACR]), age, sex, and race (African American and white). Collaborative meta-analysis. 8 general-population cohorts (1,285,049 participants) and 5 chronic kidney disease (CKD) cohorts (79,519 participants). Available eGFR, ACR, and 50 or more AKI events. Age, sex, race, eGFR, urine ACR, and interactions. Hospitalized with or for AKI, using Cox proportional hazards models to estimate HRs of AKI and random-effects meta-analysis to pool results. 16,480 (1.3%) general-population cohort participants had AKI over a mean follow-up of 4 years; 2,087 (2.6%) CKD participants had AKI over a mean follow-up of 1 year. Lower eGFR and higher ACR were strongly associated with AKI. Compared with eGFR of 80mL/min/1.73m(2), the adjusted HR of AKI at eGFR of 45mL/min/1.73m(2) was 3.35 (95% CI, 2.75-4.07). Compared with ACR of 5mg/g, the risk of AKI at ACR of 300mg/g was 2.73 (95% CI, 2.18-3.43). Older age was associated with higher risk of AKI, but this effect was attenuated with lower eGFR or higher ACR. Male sex was associated with higher risk of AKI, with a slight attenuation in lower eGFR but not in higher ACR. African Americans had higher AKI risk at higher levels of eGFR and most levels of ACR. Only 2 general-population cohorts could contribute to analyses by race; AKI identified by diagnostic code. Reduced eGFR and increased ACR are consistent strong risk factors for AKI, whereas associations of AKI with age, sex, and race may be weaker in more advanced stages of CKD.

The goal of this study was to estimate the incidence of Parkinson's disease by age, gender, and ethnicity. Newly diagnosed Parkinson's disease cases in 1994-1995 were identified among members of the Kaiser Permanente Medical Care Program of Northern California, a large health maintenance organization. Each case met modified standardized criteria/Hughes diagnostic criteria as applied by a movement disorder specialist. Incidence rates per 100,000 person-years were calculated using the Kaiser Permanente membership information as the denominator and adjusted for age and/or gender using the direct method of standardization. A total of 588 newly diagnosed (incident) cases of Parkinson's disease were identified, which gave an overall annualized age- and gender-adjusted incidence rate of 13.4 per 100,000 (95% confidence interval (CI): 11.4, 15.5). The incidence rapidly increased over the age of 60 years, with only 4% of the cases being under the age of 50 years. The rate for men (19.0 per 100,000, 95% CI: 16.1, 21.8) was 91% higher than that for women (9.9 per 100,000, 95% CI: 7.6, 12.2). The age- and gender-adjusted rate per 100,000 was highest among Hispanics (16.6, 95% CI: 12.0, 21.3), followed by non-Hispanic Whites (13.6, 95% CI: 11.5, 15.7), Asians (11.3, 95% CI: 7.2, 15.3), and Blacks (10.2, 95% CI: 6.4, 14.0). These data suggest that the incidence of Parkinson's disease varies by race/ethnicity.

Children's experiences with differently aged faces changes in the course of development. During infancy, most faces encountered are adult, however as children mature, exposure to child faces becomes more extensive. Does this change in experience influence preference for differently aged faces? The preferences of children for adult versus child, and adult versus infant faces were investigated. Caucasian 3- to 6-year-olds and adults were presented with adult/child and adult/infant face pairs which were either Caucasian or Asian (race consistent within pairs). Younger children (3 to 4 years) preferred adults over children, whereas older children (5 to 6 years) preferred children over adults. This preference was only detected for Caucasian faces. These data support a "here and now" model of the development of face age processing from infancy to childhood. In particular, the findings suggest that growing experience with peers influences age preferences and that race impacts on these preferences. In contrast, adults preferred infants and children over adults when the faces were Caucasian or Asian, suggesting an increasing influence of a baby schema, and a decreasing influence of race. The different preferences of younger children, older children, and adults also suggest discontinuity and the possibility of different mechanisms at work during different developmental periods.

The accurate estimation of age using methylation data has proved a useful and heritable biomarker, with acceleration in epigenetic age predicting a number of age-related phenotypes. Measures of white matter integrity in the brain are also heritable and highly sensitive to both normal and pathological aging processes across adulthood. We consider the phenotypic and genetic interrelationships between epigenetic age acceleration and white matter integrity in humans. Our goal was to investigate processes that underlie interindividual variability in age-related changes in the brain. Using blood taken from a Mexican-American extended pedigree sample ( n = 628; age = 23.28-93.11 years), epigenetic age was estimated using the method developed by Horvath (2013). For n = 376 individuals, diffusion tensor imaging scans were also available. The interrelationship between epigenetic age acceleration and global white matter integrity was investigated with variance decomposition methods. To test for neuroanatomical specificity, 16 specific tracts were additionally considered. We observed negative phenotypic correlations between epigenetic age acceleration and global white matter tract integrity (ρ pheno = -0.119, p = 0.028), with evidence of shared genetic (ρ gene = -0.463, p = 0.013) but not environmental influences. Negative phenotypic and genetic correlations with age acceleration were also seen for a number of specific white matter tracts, along with additional negative phenotypic correlations between granulocyte abundance and white matter integrity. These findings (i.e., increased acceleration in epigenetic age in peripheral blood correlates with reduced white matter integrity in the brain and shares common genetic influences) provide a window into the neurobiology of aging processes within the brain and a potential biomarker of normal and pathological brain aging. SIGNIFICANCE STATEMENT Epigenetic measures can be used to predict age with a high degree of accuracy and so

Reliable community-based colorectal adenoma prevalence estimates are needed to inform colonoscopy quality standards and to estimate patient colorectal cancer risks; however, minimal data exist from populations with large numbers of diverse patients and examiners. We evaluated the prevalence of adenomas detected by sex, age, race/ethnicity, and colon location among 20,792 Kaiser Permanente Northern California members ≥50 years of age who received a screening colonoscopy examination (102 gastroenterologists, 2006-2008). Prevalence of detected adenomas increased more rapidly with age in the proximal colon (adjusted odds ratio [OR], 2.39; 95% confidence interval [CI], 2.05-2.80; 70-74 vs 50-54 years) than in the distal colon (OR, 1.89; 95% CI, 1.63-2.19). Prevalence was higher among men vs women at all ages (OR, 1.77; 95% CI, 1.66-1.89), increasing in men from 25% to 39% at ≥70 years and in women from 15% at 50-54 years to 26% (P < .001). Proximal adenoma prevalence was higher among blacks than whites (OR, 1.26; 95% CI, 1.04-1.54), although total prevalence was similar, including persons <60 years old (OR, 1.17; 95% CI, 0.91-1.50). Prevalence of detected adenomas increases substantially with age and is much higher in men; proximal adenomas are more common among blacks than whites, although the total prevalence and the prevalence for ages <60 years were similar by race. These demographic differences are such that current adenoma detection guidelines may not be valid, without adjustment, for comparing providers serving different populations. The variation in prevalence and location may also have implications for the effectiveness of screening methods in different demographic groups. Copyright © 2013 AGA Institute.

Saliva is essential to maintain and preserve oral health. Previous studies of primarily white populations demonstrated that salivary gland flow rates are age-stable in healthy adults, but there are little data on African Americans of different ages. The purpose of this study was to determine if there is a relationship between age, gender, and race in unstimulated and stimulated parotid and submandibular salivary gland flow rates and to evaluate subjective responses to questions regarding salivary dysfunction. Sixty generally healthy, middle socioeconomic class African Americans and whites between the ages of 20 to 40 and 60 to 80 years were evaluated. The results indicate, in general, that objective and subjective measurements of major salivary gland flow rates are independent of age, gender, and race. Further studies are required using larger populations. These results suggest that signs and symptoms of dry mouth in the elderly regardless of race or gender should not be considered a normal sequela of aging. PMID:7897685

To assess whether literacy, numeracy, and optimism are related to low-income adults' satisfaction with their healthcare provider's communication skills. Low-income adults (N=131) were recruited from seven counties in Indiana through University extension programs. To achieve research triangulation, participants were surveyed and interviewed about their communication satisfaction with health providers. Survey data revealed that four variables significantly predicted satisfaction: age, race, literacy, and optimism. Low-income adults in the current study were more critical of their healthcare provider's communication skills if they were younger, White, functionally literate, and pessimistic. Follow-up interviews confirmed this pattern and suggested it was a byproduct of patient activism. In low-income populations, communication satisfaction may be lower for groups that are traditionally active in doctor-patient interactions (e.g., younger patients, patients with higher literacy skills). Healthcare providers should be aware that older, non-White, optimistic, and literacy deficient patients report greater communication satisfaction than their younger, White, pessimistic, and functionally literate peers. Both groups may be coping with their situation, the former by withdrawing and the latter by actively pushing for a higher standard of care. Healthcare providers should continue to seek out ways to facilitate dialogue with these underserved groups. 2009 Elsevier Ireland Ltd. All rights reserved.

Analyzing the Effects of Stellar Evolution on White Dwarf Ages

White dwarfs are among the oldest objects in our Galaxy, thus if we can determine their ages, we can derive the star formation history of our Galaxy. As part of a larger project that will use Gaia parallaxes to derive the ages of tens of thousands of white dwarfs, we explore the impact on the total white dwarf age of various modern models of main sequence and red giant branch stellar evolution, as well as uncertainties in progenitor metallicity. In addition, we study the effect on white dwarf ages caused by uncertainties in the Initial Final Mass Relation, which is the mapping between zero age main sequence and white dwarf masses. We find that for old and high mass white dwarfs, uncertainties in these factors have little effect on the total white dwarf age.

The confounding of race and geography: how much of the excess stroke mortality among African Americans is explained by geography?

The excess stroke mortality among African Americans and Southerners is well known. Because a higher proportion of the population living in the 'Stroke Belt' is African American, then a portion of the estimated excess risk of stroke death traditionally associated with African-American race may be attributable to geography (i.e., race and geography are 'confounded'). In this paper we estimate the proportion of the excess stroke mortality among African Americans that is attributable to geography. The numbers of stroke deaths at the county level are available from the vital statistics system of the US. A total of 1,143 counties with a population of at least 500 whites and 500 African Americans were selected for these analyses. The black-to-white stroke mortality ratio was estimated with and without adjustment for county of residence for those aged 45-64 and for those aged 65 and over. The difference in the stroke mortality ratio before versus after adjustment for county provides an estimate of the proportion of the excess stroke mortality inappropriately attributed to race (that is in fact attributable to geographic region). For ages 45-64, the black-to-white stroke mortality ratio was reduced from 3.41 to 3.04 for men, and from 2.82 to 2.60 for women, suggesting that between 10 and 15% of the excess mortality traditionally attributed to race is rather due to geography. Over the age of 65, the black-to-white stroke mortality ratio was reduced from 1.31 to 1.27 for men, and from 1.097 to 1.095 for women, suggesting that between 2 and 13% of the excess mortality attributed to black race is actually attributable to geography. The reductions of all the four age strata gender groups were highly significant. These results suggest that a significant, although relatively small, proportion of the excess mortality traditionally attributed to race is rather a factor of geography. Copyright 2004 S.

Although US year 2000 guidelines recommended characterizing breast cancers by human epidermal growth factor receptor 2 (HER2), national cancer registries do not collect HER2, rendering a population-based understanding of HER2 and clinical "triple subtypes" (estrogen receptor [ER] / progesterone receptor [PR] / HER2) largely unknown. We document the population-based prevalence of HER2 testing / status, triple subtypes and present the first report of subtype incidence rates. Medical records were searched for HER2 on 1842 metropolitan Atlanta females diagnosed with breast cancer during 2003-2004. HER2 testing/status and triple subtypes were analyzed by age, race/ethnicity, tumor factors, socioeconomic status, and treatment. Age-adjusted incidence rates were calculated. Over 90% of cases received HER2 testing: 12.6% were positive, 71.7% negative, and 15.7% unknown. HER2 testing compliance was significantly better for women who were younger, of Caucasian or African-American descent, or diagnosed with early stage disease. Incidence rates (per 100,000) were 21.1 for HER2+ tumors and 27.8 for triple-negative tumors, the latter differing by race (36.3 and 19.4 for black and white women, respectively). HER2 recommendations are not uniformly adhered to. Incidence rates for breast cancer triple subtypes differ by age/race. As biologic knowledge is translated into the clinical setting eg, HER2 as a biomarker, it will be incumbent upon national cancer registries to report this information. Incidence rates cautiously extrapolate to an annual burden of 3000 and 17,000 HER2+ tumors for black and white women, respectively, and triple-negative tumors among 5000 and 16,000 respectively. Testing, rate, and burden variations warrant population-based in-depth exploration and clinical translation. (c) 2010 American Cancer Society.

Sexual Behavior Varies Between Same-Race and Different-Race Partnerships: A Daily Diary Study of Highly Sexually Active Black, Latino, and White Gay and Bisexual Men.

Racial homophily (partnering with those of the same race) has been suggested as contributing to racial disparities in HIV among gay and bisexual men (GBM). Using a daily diary study, we examined racial homophily and its role in anal sexual behaviors in a sample of highly sexually active Black, White, and Latino GBM (N = 294, n = 3107 sexual events). In general, (1) men tended to partner with others of the same race, (2) HIV was more prevalent among men of color, and (3) race acted independent of whether one would engage in behaviors that would put them at highest risk for transmitting HIV (i.e., no main or interaction effects for insertive condomless anal sex (CAS) among HIV-positive men, and no main or interaction effects for receptive CAS among HIV-negative men). There were some main and interactive effects observed for lower risk behaviors (receptive CAS among HIV-positive men and insertive CAS among HIV-negative). Our findings suggest that racial disparities in HIV may be due to a higher exposure frequency (i.e., the frequency with which one comes into contact with a partner where a transmission could occur). However, men were also less likely to have anal sex when having sex with someone of the same race-a finding that works against the premise of higher exposure frequency. Future researchers should examine both racial homophily as well as variation in sexual behavior based on same-race or different-race partnerships.

Racial differences are known to account for a higher incidence of systemic lupus erythematosus (SLE), as well as increased disease severity and mortality. The purpose of this study was to determine whether there are any race-specific risk factors that affect measures of subclinical atherosclerosis in SLE patients. Traditional and SLE-related cardiovascular disease (CVD) risk factors were assessed in 106 female SLE patients. Carotid medial intimal medial thickness (mIMT) and coronary artery calcification (CAC) were measured on all subjects. Differences were evaluated between races for all clinical, serologic, and CVD risk factors and the racial interactions with all covariables. Outcomes included mIMT and CAC. There were no significant differences between races with regard to mIMT or CAC. Significant covariables in the final model for mIMT included age, triglycerides, glucose, and race-age and race-smoking interactions. A prediction model with fixed significant covariables demonstrated that Black subjects with a smoking history had a significantly higher mIMT than Blacks who had never smoked, an effect not seen in Whites. There were no differences between having CAC or with the CAC scores between the races. In the final model for CAC, age and SLE disease duration were significant covariables impacting CAC. When controlling for other significant CVD covariables and interactions, Black women, but not White, with SLE with a history of smoking have higher mIMT measurements than those who have never smoked. This is the first report documenting the race-specific effect of smoking on subclinical measures of CVD in SLE.

National heart failure (HF) hospitalization rates have not been appropriately age standardized by sex or race/ethnicity. Reporting hospital utilization trends by subgroup is important for monitoring population health and developing interventions to eliminate disparities. The National Inpatient Sample (NIS) was used to estimate the crude and age-standardized rates of HF hospitalization between 2002 and 2013 by sex and race/ethnicity. Direct standardization was used to age-standardize rates to the 2000 US standard population. Relative differences between subgroups were reported. The national age-adjusted HF hospitalization rate decreased 30.8% from 526.86 to 364.66 per 100 000 between 2002 and 2013. Although hospitalizations decreased for all subgroups, the ratio of the age-standardized rate for men compared with women increased from 20% greater to 39% ( P trend=0.002) between 2002 and 2013. Black men had a rate that was 229% ( P trend=0.141) and black women, 240% ( P trend=0.725) with reference to whites in 2013 with no significant change between 2002 and 2013. Hispanic men had a rate that was 32% greater in 2002 and the difference narrowed to 4% ( P trend=0.047) greater in 2013 relative to whites. For Hispanic women, the rate was 55% greater in 2002 and narrowed to 8% greater ( P trend=0.004) in 2013 relative to whites. Asian/Pacific Islander men had a 27% lower rate in 2002 that improved to 43% ( P trend=0.040) lower in 2013 relative to whites. For Asian/Pacific Islander women, the hospitalization rate was 24% lower in 2002 and improved to 43% ( P trend=0.021) lower in 2013 relative to whites. National HF hospitalization rates have decreased steadily during the recent decade. Disparities in HF burden and hospital utilization by sex and race/ethnicity persist. Significant population health interventions are needed to reduce the HF hospitalization burden among blacks.

2014-06-01

To examine the associations of: (a) neonatal sex with mild-to-moderate and severe birth asphyxia, (b) fetal sex with mortality due to birth asphyxia and (c) neonatal race with severe birth asphyxia. We used the Nationwide Inpatient Sample (NIS) Database including the years 1993 to 2008 or its pediatric sub portion Kid's Inpatient Database (KID) for the years 1997, 2000, 2003 and 2006. NIS database is collected annually from more than 1000 hospitals across the United States for millions of inpatient discharge summaries. We included newborns older than 36 weeks gestational age or more than 2500 g at birth. We excluded newborns with congenital heart disease, major congenital anomalies and chromosomal disorders. We compared birth asphyxia in males to females, and in each race compared with whites, and examined effect of sex in association with birth asphyxia within each race/ethnicity. There were 9 708 251 term infants (51.8% males) included in the study. There were 15 569 newborns diagnosed with severe birth asphyxia (1.6 in 1000); of them 56.1% were males. Odds ratio (OR)to have severe birth asphyxia in male newborns was 1.16 (confidence interval (CI): 1.12 to 1.20, P<0.001). Compared with Whites, African-American newborns had more birth asphyxia, OR 1.23 (CI: 1.16 to 1.31, P<0001), whereas Hispanics and Asians had less birth asphyxia. Native American newborns did not differ from their white counterparts. On comparing males to females within each race, male sex was associated with increased birth asphyxia in all races but Native American. Male sex and African-American race were associated with increased prevalence of birth asphyxia.

The reported incidence of molar pregnancy varies widely among different geographic locations. This variation has been attributed, at least in part, to racial/ethnic differences. While the incidence of molar pregnancies is decreasing, certain ethnic groups such as Hispanics, Asians, and American Indians continue to have an increased risk of developing gestational trophoblastic disease across the globe. We sought to describe the potential effect of ethnicity/race on the presentation and clinical course of complete mole and partial mole. All patients followed up for complete mole and partial mole at a single institution referral center from 1994 through 2013 were identified. Variables including age, race, gravidity, parity, gestational age, presenting signs/symptoms, serum human chorionic gonadotropin values, and development of gestational trophoblastic neoplasia were extracted from medical records and patient surveys. Patients with complete mole and partial mole were categorized into race/ethnicity groups defined as white, black, Asian, or Hispanic. Due to low numbers of non-white patients with partial mole in each non-white category, patients with partial mole were grouped as white or non-white. Continuous variables were compared using the Kruskal-Wallis test and binary variables were compared using the Fisher exact test. A total of 167 complete mole patients with known race/ethnicity status were included (57.48% white, 14.97% Asian, 14.37% black, 13.17% Hispanic). Hispanics presented at younger age (median 24.5 years) compared to whites (median 32.0 years, P = .04) and Asians (median 31.0 years, P = .03). Blacks had higher gravidity than whites (P < .001) and Hispanics (P = .05). There was no significant difference in presenting symptoms, gestational age at diagnosis, and preevacuation serum human chorionic gonadotropin level by race/ethnicity. Hispanics were significantly less likely than whites to develop gestational trophoblastic neoplasia (absolute risk

To examine nurses' self-reported use of race in clinical evaluation. This cross-sectional study analyzed data collected from three separate studies using the Genetics and Genomics in Nursing Practice Survey, which includes items about use of race and genomic information in nursing practice. The Racial Attributes in Clinical Evaluation (RACE) scale was used to measure explicit clinical use of race among nurses from across the United States. Multivariate regression analysis was used to examine associations between RACE score and individual-level characteristics and beliefs in 5,733 registered nurses. Analysis revealed significant relationships between RACE score and nurses' race and ethnicity, educational level, and views on the clinical importance of patient demographic characteristics. Asian nurses reported RACE scores 1.41 points higher than White nurses (p < .001), and Black nurses reported RACE scores 0.55 points higher than White nurses (p < .05). Compared to diploma-level nurses, the baccalaureate-level nurses reported 0.69 points higher RACE scores (p < .05), master's-level nurses reported 1.63 points higher RACE scores (p < .001), and doctorate-level nurses reported 1.77 points higher RACE scores (p < .01). In terms of clinical importance of patient characteristics, patient race and ethnicity corresponded to a 0.54-point increase in RACE score (p < .001), patient genes to a 0.21-point increase in RACE score (p < .001), patient family history to a 0.15-point increase in RACE score (p < .01), and patient age to a 0.19-point increase in RACE score (p < .001). Higher reported use of race among minority nurses may be due, in part, to differential levels of racial self-awareness. A relatively linear positive relationship between level of nursing degree nursing education and use of race suggests that a stronger foundation of knowledge about genetic ancestry, population genetics and the concept "race" and genetic ancestry may increase in clinical decision making

Relationship between age and elite marathon race time in world single age records from 5 to 93 years

2014-01-01

Background The aims of the study were (i) to investigate the relationship between elite marathon race times and age in 1-year intervals by using the world single age records in marathon running from 5 to 93 years and (ii) to evaluate the sex difference in elite marathon running performance with advancing age. Methods World single age records in marathon running in 1-year intervals for women and men were analysed regarding changes across age for both men and women using linear and non-linear regression analyses for each age for women and men. Results The relationship between elite marathon race time and age was non-linear (i.e. polynomial regression 4th degree) for women and men. The curve was U-shaped where performance improved from 5 to ~20 years. From 5 years to ~15 years, boys and girls performed very similar. Between ~20 and ~35 years, performance was quite linear, but started to decrease at the age of ~35 years in a curvilinear manner with increasing age in both women and men. The sex difference increased non-linearly (i.e. polynomial regression 7th degree) from 5 to ~20 years, remained unchanged at ~20 min from ~20 to ~50 years and increased thereafter. The sex difference was lowest (7.5%, 10.5 min) at the age of 49 years. Conclusion Elite marathon race times improved from 5 to ~20 years, remained linear between ~20 and ~35 years, and started to increase at the age of ~35 years in a curvilinear manner with increasing age in both women and men. The sex difference in elite marathon race time increased non-linearly and was lowest at the age of ~49 years. PMID:25120915

Mere Exposure and Racial Prejudice: Exposure to Other-Race Faces Increases Liking for Strangers of That Race

White participants were exposed to other-race or own-race faces to test the generalized mere exposure hypothesis in the domain of face perception, namely that exposure to a set of faces yields increased liking for similar faces that have never been seen. In Experiment 1, rapid supraliminal exposures to Asian faces increased White participants' subsequent liking for a different set of Asian faces. In Experiment 2, subliminal exposures to Black faces increased White participants' subsequent liking for a different set of Black faces. The findings are consistent with prominent explanations for mere exposure effects as well as with the familiar face overgeneralization hypothesis that prejudice derives in part from negative reactions to faces that deviate from the familiar own-race prototype, PMID:19584948

2016-01-01

Objectives: the objective of this study was to explore whether race-based difference in fall risk may be mediated by environmental and physical performance risk factors. Methods: using data from a nationally representative longitudinal survey of 7,609 community-dwelling participants in the National Health and Aging Trends Study (NHATS), we evaluated whether racial differences in fall risk may be explained by physical performance level (measured by the Short Physical Performance Battery), mobility disability, physical activity level and likelihood of living alone. Multivariate Poisson regression and mediation models were used in analyses. Results: in whites and blacks, the annual incidence of ‘any fall’ was 33.8 and 27.1%, respectively, and the annual incidence of ‘recurrent falls’ was 15.5 and 12.3%, respectively. Compared with whites, blacks had relative risks of 0.7 (95% confidence interval 0.6–0.8) and 0.6 (0.5–0.8) for sustaining any fall and recurrent falls, respectively, in adjusted analyses. Blacks had poorer performance on the SPPB (P < 0.001), higher levels of mobility disability (P < 0.001), similar levels of physical activity (P = 0.19) and were equally likely to live alone relative to whites (P = 0.77). Mediation analysis revealed that these risk factors collectively acted as suppressors and none of these factors accounted for the racial differences in fall risk observed. Conclusions: relative to whites, blacks were at 30 and 40% decreased risk of sustaining any fall and recurrent falls, respectively. This difference in risk remains unexplained. PMID:26764401

Where and when adolescents use tobacco, alcohol, and marijuana: comparisons by age, gender, and race.

This study examined the location and time of adolescent use of cigarettes, alcohol, and marijuana. Age, gender, and racial differences in location and time of use were studied for each substance. Using cross-sectional data collected through the schoolwide Pride Survey, 20,055 students between the ages of 10 and 19 years (53.6% female, 55.1% Black, 44.9% White) in one metropolitan area reported on their frequency of cigarette, alcohol, and marijuana use, as well as the location and time of use of each substance. Chi-square tests compared the rates, locations, and times for each substance across boys and girls; Black and White students; and early, middle, and late adolescents. Older adolescents reported higher rates of substance use at friends' homes, at school, and in cars and lower rates of alcohol use at home compared with younger youth. Males were more likely to report alcohol and marijuana use at school and on weeknights and alcohol use in cars, whereas females were more likely to report alcohol and marijuana use on the weekends. No gender differences emerged for times and locations of cigarette use. Compared with Black youth, White adolescents were more likely to use all substances at friends' homes and on weekends; to smoke cigarettes at school, in the car, and on weeknights; and to use alcohol at home. Black adolescents were more likely to report using alcohol at home, at school, in cars, during and after school, and on weeknights and were more likely to report using marijuana at school. The location and time of adolescent substance use vary substantially by age, gender, and race. These differences may help tailor substance use prevention and intervention programs to specific subgroups of youth to improve program effectiveness.

To assess whether black race and other cerebrovascular risk factors have a differential effect on first vs. recurrent stroke events. Estimate the differences in the magnitude of the association of demographic (age, back race, sex) or stroke risk factors (hypertension, diabetes, cigarette smoking, atrial fibrillation, left ventricular hypertrophy, or heart disease) for first vs. recurrent stroke from a longitudinal cohort study of 29,682 black or white participants aged 45 years and older. Over an average 6.8 years follow-up, 301 of 2,993 participants with a previous stroke at baseline had a recurrent stroke, while 818 of 26,689 participants who were stroke-free at baseline had a first stroke. Among those stroke-free at baseline, there was an age-by-race interaction (p = 0.0002), with a first stroke risk 2.70 (95% confidence interval: 1.86-3.91) times greater for black than white participants at age 45, but no racial disparity at age 85 (hazard ratio = 0.91; 95% confidence interval: 0.70-1.18). In contrast, there was no evidence of a higher risk of recurrent stroke at any age for black participants (p > 0.05). The association of traditional stroke risk factors was generally similar for first and recurrent stroke. The association of age and black race differs substantially on first vs. recurrent stroke risk, with risk factors playing a similar role. © 2016 American Academy of Neurology.

Using the Early Childhood Longitudinal Study-Birth Cohort (N≅8,550), this study examines associations between extended household transitions and age 2 cognitive development. A substantial minority of toddlers experiences these transitions, and their consequences vary by household member type, entry versus exit, and race/ethnicity. Extended household transitions predict lower cognitive scores for white children, but the selection of low-socioeconomic status families into extended households explains these disparities. Grandparent transitions predict significantly higher cognitive scores for African American and Latino children than whites, and some “other adult” transitions predict higher scores for Latinos than African Americans and whites. Extended household transitions’ consequences are independent of co-occurring residential moves and partner transitions. Findings suggest that studying extended household transitions is useful for understanding children’s early development, and their consequences vary by race/ethnicity. PMID:23017924

Beyond Black and White: Color and Mortality in Post Reconstruction Era North Carolina

A growing empirical literature in economics and sociology documents the existence of differences in social and economic outcomes between mixed-race blacks and other blacks . However, few researchers have considered whether the advantages associated with mixed-race status may have also translated into differences in mortality outcomes between subgroups of blacks and how both groups compared to whites. We employ previously untapped 1880 North Carolina Mortality census records in conjunction with data from the 1880 North Carolina Population Census to examine whether mulatto, or mixed-race blacks may have experienced mortality advantages over to their colored, or non-mixed race counterparts. For men between the ages of 20-44, estimates demonstrate that all black males are more likely than whites to die. Although our results indicate that there are no statistically significant differences in mortality between mulatto and colored blacks, there are some indications that mulatto males may have enjoyed a slight mortality advantage compared to their colored counterparts. However, we find a substantial mortality advantage associated with mixed-race status among women. These findings indicate that mixed-race women, rather than men, may have accrued any mortality advantages associated with color and white ancestry. PMID:25722496

Race and ethnicity responses can change over time and across contexts – a component of population change not usually considered in studies that use race and ethnicity as variables. To facilitate incorporation of this aspect of population change, we show patterns and directions of individual-level race and Hispanic response change throughout the U.S. and among all federally recognized race/ethnic groups. We use internal Census Bureau data from the 2000 and 2010 censuses in which responses have been linked at the individual level (N = 162 million). About 9.8 million people (6.1 percent) in our data have a different race and/or Hispanic origin response in 2010 than they did in 2000. Race response change was especially common among those reported as American Indian, Alaska Native, Native Hawaiian, Other Pacific Islander, in a multiple-race response group, or Hispanic. People reported as non-Hispanic white, black, or Asian in 2000 usually had the same response in 2010 (3%, 6% and 9% of responses changed, respectively). Hispanic/non-Hispanic ethnicity responses were also usually consistent (13% and 1% changed). There were a variety of response change patterns, which we detail. In many race/Hispanic response groups, there is population churn in the form of large countervailing flows of response changes that are hidden in cross-sectional data. We find that response changes happen across ages, sexes, regions, and response modes, with interesting variation across race/ethnic categories. Researchers should think through and discuss the implications of race and Hispanic origin response change when designing analyses and interpreting results. PMID:28105578

Whether the association of blood pressure (BP) during sleep (nocturnal BP) with cognition differs by race is unknown. Participants in the GENOA (Genetic Epidemiology Network of Arteriopathy) Study underwent ambulatory BP measurements, brain magnetic resonance imaging, and cognitive function testing (the Rey Auditory Verbal Learning Test, the Digit Symbol Substitution Task, and the Trail Making Test Part B) between 2000 and 2007. We examined multivariable linear regression models of the nocturnal BP-cognition association. Among 755 participants (mean age, 63 years; 64% women; 42% self-identified black race; 76% taking antihypertensive medication), mean nocturnal systolic BP (SBP)/diastolic BP was 126/69 mm Hg, daytime SBP/diastolic BP level was 139/82 mm Hg, and mean reduction in SBP from day to night (dipping) was 9%. Among the entire sample, a race interaction was observed in Digit Symbol Substitution Task and Trail Making Test Part B (both P <0.15). Race-stratified analyses showed that a 1-SD increase in nocturnal SBP levels was associated with poorer Digit Symbol Substitution Task and log-transformed Trail Making Test Part B scores (unstandardized regression coefficient [95% confidence interval]: -1.98 [-3.28 to -0.69] and 0.06 [0.004-0.12]; both P< 0.05) in black but not white individuals. Additional adjustments for white matter hyperintensity volumes or brain atrophy, measured via brain magnetic resonance imaging, did not change the results. Results were similar when nocturnal SBP dipping was assessed as the exposure, yet daytime SBP levels yielded no association with cognition. Nocturnal SBP measurements may be useful in assessing the potential risk for lower cognitive function in middle-aged and older adults, particularly in black individuals. © 2017 The Authors.

Race is associated with social relationships among typically developing children; however, studies rarely examine the impact of race on social outcomes for children with autism spectrum disorder. This study examined how race (African American, Latino, Asian, or White) in conjunction with disability status (autism spectrum disorders or typically developing) and grade (grades K-2 or 3-5) affects friendships and social networks. The sample comprises 85 children with autism spectrum disorders and 85 typically developing controls matched on race, gender, age/grade, and classroom (wherever possible). Race, disability, and grade each had an independent effect on friendship nominations, and there was an interaction among the three variables. Specifically, children with autism spectrum disorders who were African American or Latino in the upper elementary grades received fewer friendship nominations than typically developing White children in the lower elementary grades. Only the presence of autism spectrum disorders was associated with social network centrality. Our results also suggested that Latino children with autism spectrum disorders in the upper elementary grades were at the highest risk of social isolation. Implications for re-conceptualizing social skills interventions are discussed. © The Author(s) 2016.

The goals of this study were to examine the relationship between age at first drink and age at first sex among an emergency department sample of Black, Hispanic, and White adolescents (N = 1,1110) and to assess two sexual behavior-related consequences of underage drinking. The authors used multivariable linear regression to analyze data from a self-reported survey. Age at first sex decreased linearly with decreasing age at first drink (p < .001) for all adolescents in the sample. In analyses stratified by race, significant positive trends between age at first drink and age at first sex were observed for all race and ethnic subgroups, although the relationship between age at first drink and age at first sex was not as strong for Black males and females as their White counterparts, respectively. Compared to White males, Black males were less likely to report having had sex without using a condom or birth control after drinking in the past month and during their lifetimes.

Race and current socioeconomic status (SES) are associated with sleep. Parental education, a commonly studied component of childhood SES, is predictive of adult health outcomes; yet, its impact on adult sleep remains unclear. In this study, the sleep of 128 Black and White adults was investigated. Participants with lower childhood SES (assessed via parental education) spent more time in Stage 2 sleep and less time in slow-wave sleep (SWS) than those with higher childhood SES. In addition, women from low childhood SES backgrounds took longer to fall asleep than women from high SES backgrounds. Black participants spent less time in SWS than their White counterparts, and an Age × Race interaction was detected in the prediction of subjective sleep quality. Results were not mediated via current SES or health practices.

Ecology-driven stereotypes override race stereotypes

Why do race stereotypes take the forms they do? Life history theory posits that features of the ecology shape individuals’ behavior. Harsh and unpredictable (“desperate”) ecologies induce fast strategy behaviors such as impulsivity, whereas resource-sufficient and predictable (“hopeful”) ecologies induce slow strategy behaviors such as future focus. We suggest that individuals possess a lay understanding of ecology’s influence on behavior, resulting in ecology-driven stereotypes. Importantly, because race is confounded with ecology in the United States, we propose that Americans’ stereotypes about racial groups actually reflect stereotypes about these groups’ presumed home ecologies. Study 1 demonstrates that individuals hold ecology stereotypes, stereotyping people from desperate ecologies as possessing faster life history strategies than people from hopeful ecologies. Studies 2–4 rule out alternative explanations for those findings. Study 5, which independently manipulates race and ecology information, demonstrates that when provided with information about a person’s race (but not ecology), individuals’ inferences about blacks track stereotypes of people from desperate ecologies, and individuals’ inferences about whites track stereotypes of people from hopeful ecologies. However, when provided with information about both the race and ecology of others, individuals’ inferences reflect the targets’ ecology rather than their race: black and white targets from desperate ecologies are stereotyped as equally fast life history strategists, whereas black and white targets from hopeful ecologies are stereotyped as equally slow life history strategists. These findings suggest that the content of several predominant race stereotypes may not reflect race, per se, but rather inferences about how one’s ecology influences behavior. PMID:26712013

Blood cadmium by race/hispanic origin: The role of smoking

DOE Office of Scientific and Technical Information (OSTI.GOV)

Aoki, Yutaka, E-mail: yaoki@cdc.gov

Background: There have been increasing concerns over health effects of low level exposure to cadmium, especially those on bones and kidneys. Objective: To explore how age-adjusted geometric means of blood cadmium in adults varied by race/Hispanic origin, sex, and smoking status among U.S. adults and the extent to which the difference in blood cadmium by race/Hispanic origin and sex may be explained by intensity of smoking, a known major source of cadmium exposure. Methods: Our sample included 7,368 adults from National Health and Nutrition Examination Survey (NHANES) 2011–2014. With direct age adjustment, geometric means of blood cadmium and number ofmore » cigarettes smoked per day were estimated for subgroups defined by race/Hispanic origin, smoking status, and sex using interval regression, which allows mean estimation in the presence of left- and right-censoring. Results: Among never and former smoking men and women, blood cadmium tended to be higher for non-Hispanic Asian adults than adults of other race/Hispanic origin. Among current smokers, who generally had higher blood cadmium than never and former smokers, non-Hispanic white, black, and Asian adults had similarly elevated blood cadmium compared to Hispanic adults. A separate analysis revealed that non-Hispanic white adults tended to have the highest smoking intensity regardless of sex, than adults of the other race/Hispanic origin groups. Conclusions: The observed pattern provided evidence for smoking as a major source of cadmium exposure, yet factors other than smoking also appeared to contribute to higher blood cadmium of non-Hispanic Asian adults. - Highlights: • Among never and former smoking adults, Asians have the highest blood cadmium. • White adults tend to have the highest smoking intensity, but not blood cadmium. • Women overall have higher levels of blood cadmium than men regardless of smoking. • Non-smoking sources of exposure likely contribute to Asians’ higher blood cadmium.« less

Patients are being encouraged to go online to obtain health information and interact with their health care systems. However, a 2014 survey found that less than 60% of American adults aged 65 and older use the Internet, with much lower usage among black and Latino seniors compared with non-Hispanic white seniors, and among older versus younger seniors. Our aims were to (1) identify race/ethnic and age cohort disparities among seniors in use of the health plan's patient portal, (2) determine whether race/ethnic and age cohort disparities exist in access to digital devices and preferences for using email- and Web-based modalities to interact with the health care system, (3) assess whether observed disparities in preferences and patient portal use are due simply to barriers to access and inability to use the Internet, and (4) learn whether older adults not currently using the health plan's patient portal or website have a potential interest in doing so in the future and what kind of support might be best suited to help them. We conducted two studies of seniors aged 65-79 years. First, we used administrative data about patient portal account status and utilization in 2013 for a large cohort of English-speaking non-Hispanic white (n=183,565), black (n=16,898), Latino (n=12,409), Filipino (n=11,896), and Chinese (n=6314) members of the Kaiser Permanente Northern California health plan. Second, we used data from a mailed survey conducted in 2013-2014 with a stratified random sample of this population (final sample: 849 non-Hispanic white, 567 black, 653 Latino, 219 Filipino, and 314 Chinese). These data were used to examine race/ethnic and age disparities in patient portal use and readiness and preferences for using digital communication for health-related purposes. Adults aged 70-74 and 75-79 were significantly less likely than 65-69 year olds to be registered to use the patient portal, and among those registered, to have used the portal to send messages, view lab test

Vitamin D intakes of children differ by race/ethnicity, sex, age, and income in the United States, 2007 to 2010.

The 2007-2010 National Health and Nutrition Examination Survey was used to estimate vitamin D intakes of children 1 to 18 years old in the United States by race/ethnicity, sex, age, and family using 24-hour dietary intake recalls and dietary supplement use questionnaires. We hypothesized that total, dietary, and supplemental vitamin D intakes of children would differ by race/ethnicity, sex, age, and income. Statistical analyses of weighted data were performed using Statistical Analysis Software (V 9.2) to estimate means ± SE. Race and ethnic intake differences controlling for poverty income ratio (PIR), sex, and age were assessed by analysis of covariance. Total (dietary and supplement) vitamin D intake was greater in the high (7.9 ± 0.3 μg/d) vs the medium (6.5 ± 0.3 μg/d) income group, but not the low (7.2 ± 0.2 μg/d) PIR group. Total vitamin D intake of non-Hispanic (NH) white children (8.1 ± 0.2 μg/d) was greater than Hispanic (7.0 ± 0.2 μg/d) and NH black (5.9 ± 0.2 μg/d) children. Total vitamin D intake declined with age, and intake by boys was higher than girls. Only 17.4% of the children consumed supplements containing vitamin D. Overall, mean intake of vitamin D by all children in each age and ethnic group was lower than the estimated average requirement for vitamin D. Public health efforts should encourage consumption of foods high in vitamin D, expand the number of foods fortified, and target health messages to parents to increase use of vitamin D supplements by children.

Although both race and socioeconomic status are well known to influence mortality patterns in the United States, few studies have examined the simultaneous influence of these factors on cancer incidence and mortality. We examined relationships among race, education level, and mortality from cancers of the lung, breast, prostate, colon and rectum, and all sites combined in contemporary US vital statistics. Age-adjusted cancer death rates (with 95% confidence intervals [CIs]) were calculated for 137,708 deaths among 119,376,196 individuals aged 25-64 years, using race and education information from death certificates and population denominator data from the US Bureau of the Census, for 47 states and Washington, DC, in 2001. Relative risk (RR) estimates were used to compare cancer death rates in persons with 12 or fewer years of education with those in persons with more than 12 years of education. Educational attainment was strongly and inversely associated with mortality from all cancers combined in black and white men and in white women. The all-cancer death rates were nearly identical for black men and white men with 0-8 years of education (224.2 and 223.6 per 100,000, respectively). The estimated relative risk for all-cancer mortality comparing the three lowest (< or = 12 years) with the three highest (> 12 years) education categories was 2.38 (95% CI = 2.33 to 2.43) for black men, 2.24 (95% CI = 2.23 to 2.26) for white men, 1.43 (95% CI = 1.41 to 1.46) for black women, and 1.76 (95% CI = 1.75 to 1.78) for white women. For both men and women, the magnitude of the relative risks comparing the three lowest educational levels with the three highest within each race for all cancers combined and for lung and colorectal cancers was higher than the magnitude of the relative risks associated with race within each level of education, whereas for breast and prostate cancer the magnitude of the relative risks associated with race was higher than the magnitude of the relative

This study investigated age, sex, and race/ethnicity risk patterns for homicide based on 246 children (newborn to 14 years old) who were murdered in the city of Los Angeles 1980 through 1989. Rates of homicide are higher for newborn to 4-year-olds than for 5- to 14-year-olds. Boys and girls have similar rates of homicide at young ages; among 5- to 14-year-olds, however, boys have higher rates. Characteristics of the victim, suspect, and event were fairly consistent across victim race/ethnicity. Rates vary by the victim's race/ethnicity; paralleling patterns among adults, rates of homicide are lowest for non-Hispanic White, higher for Hispanic, and highest for Black children. PMID:8484456

Sexual Behavior Varies Between Same-Race and Different-Race Partnerships: A Daily Diary Study of Highly Sexually Active Black, Latino, and White Gay and Bisexual Men

Racial homophily (partnering with those of the same race) has been suggested as contributing to racial disparities in HIV among gay and bisexual men (GBM). Using a daily diary study, we examined racial homophily and its role in anal sexual behaviors in a sample of highly sexually active Black, White, and Latino GBM (N = 294, n = 3107 sexual events). In general, (1) men tended to partner with others of the same race, (2) HIV was more prevalent among men of color, and (3) race acted independent of whether one would engage in behaviors that would put them at highest risk for transmitting HIV (i.e., no main or interaction effects for insertive condomless anal sex (CAS) among HIV-positive men, and no main or interaction effects for receptive CAS among HIV-negative men). There were some main and interactive effects observed for lower risk behaviors (receptive CAS among HIV-positive men and insertive CAS among HIV-negative). Our findings suggest that racial disparities in HIV may be due to a higher exposure frequency (i.e., the frequency with which one comes into contact with a partner where a transmission could occur). However, men were also less likely to have anal sex when having sex with someone of the same race—a finding that works against the premise of higher exposure frequency. Future researchers should examine both racial homophily as well as variation in sexual behavior based on same-race or different-race partnerships. PMID:26696407

The Cumulative Probability of Arrest by Age 28 Years in the United States by Disability Status, Race/Ethnicity, and Gender.

To estimate the cumulative probability (c) of arrest by age 28 years in the United States by disability status, race/ethnicity, and gender. I estimated cumulative probabilities through birth cohort life tables with data from the National Longitudinal Survey of Youth, 1997. Estimates demonstrated that those with disabilities have a higher cumulative probability of arrest (c = 42.65) than those without (c = 29.68). The risk was disproportionately spread across races/ethnicities, with Blacks with disabilities experiencing the highest cumulative probability of arrest (c = 55.17) and Whites without disabilities experiencing the lowest (c = 27.55). Racial/ethnic differences existed by gender as well. There was a similar distribution of disability types across race/ethnicity, suggesting that the racial/ethnic differences in arrest may stem from racial/ethnic inequalities as opposed to differential distribution of disability types. The experience of arrest for those with disabilities was higher than expected. Police officers should understand how disabilities may affect compliance and other behaviors, and likewise how implicit bias and structural racism may affect reactions and actions of officers and the systems they work within in ways that create inequities.

We examined the relationship between adolescents' perceptions of their close friends' attitudes about substance use, and their own use of cigarettes, alcohol, and marijuana. Using data from the 2010 National Survey on Drug Use and Health, a multistage area probability sample sponsored by the Substance Abuse and Mental Health Services Administration (n = 17,865), we tested the direct and moderating effects of subgroups of race and gender on perceptions of adolescents' close friends on past month substance use. Significant effects were found on peer attitudes influencing substance use for all race and gender subgroups. Close friends' attitudes of indifference were associated with increased substance use and disapproval associated with reduced use, controlling for age, income, family structure, and adolescents' own attitudes of risk of substance use. Significant moderating effects of peer attitudes on cigarette and marijuana use were found for both gender and race moderators. Conditional effects of the moderation by race were also examined for gender subgroups. The moderating effect of race on close friends' attitudes impacting cigarette and marijuana use was stronger in magnitude and significance for females compared to males. Female marijuana and cigarette use was more influenced by close friends' attitudes than males, and whites were more influenced by their close friends than Hispanics and blacks. White females are more susceptible to close friends' attitudes on cigarette use as compared to white males and youth of other races. Implications for socially oriented preventive interventions are discussed.

the objective of this study was to explore whether race-based difference in fall risk may be mediated by environmental and physical performance risk factors. using data from a nationally representative longitudinal survey of 7,609 community-dwelling participants in the National Health and Aging Trends Study (NHATS), we evaluated whether racial differences in fall risk may be explained by physical performance level (measured by the Short Physical Performance Battery), mobility disability, physical activity level and likelihood of living alone. Multivariate Poisson regression and mediation models were used in analyses. in whites and blacks, the annual incidence of 'any fall' was 33.8 and 27.1%, respectively, and the annual incidence of 'recurrent falls' was 15.5 and 12.3%, respectively. Compared with whites, blacks had relative risks of 0.7 (95% confidence interval 0.6-0.8) and 0.6 (0.5-0.8) for sustaining any fall and recurrent falls, respectively, in adjusted analyses. Blacks had poorer performance on the SPPB (P < 0.001), higher levels of mobility disability (P < 0.001), similar levels of physical activity (P = 0.19) and were equally likely to live alone relative to whites (P = 0.77). Mediation analysis revealed that these risk factors collectively acted as suppressors and none of these factors accounted for the racial differences in fall risk observed. relative to whites, blacks were at 30 and 40% decreased risk of sustaining any fall and recurrent falls, respectively. This difference in risk remains unexplained. © The Author 2016. Published by Oxford University Press on behalf of the British Geriatrics Society. All rights reserved.

To evaluate the association between racial residential segregation, a prominent manifestation of systemic racism, and the White-Black survival gap in a contemporary cohort of adults, and to assess the extent to which socioeconomic inequality explains this association. This was a cross sectional study of White and Black men and women aged 35-75 living in 102 large US Core Based Statistical Areas. The main outcome was the White-Black survival gap. We used 2009-2013 CDC mortality data for Black and White men and women to calculate age-, sex- and race adjusted White and Black mortality rates. We measured segregation using the Dissimilarity index, obtained from the Manhattan Institute. We used the 2009-2013 American Community Survey to define indicators of socioeconomic inequality. We estimated the CBSA-level White-Black gap in probability of survival using sequential linear regression models accounting for the CBSA dissimilarity index and race-specific socioeconomic indicators. Black men and women had a 14% and 9% lower probability of survival from age 35 to 75 than their white counterparts. Residential segregation was strongly associated with the survival gap, and this relationship was partly, but not fully, explained by socioeconomic inequality. At the lowest observed level of segregation, and with the Black socioeconomic status (SES) assumed to be at the White SES level scenario, the survival gap is essentially eliminated. White-Black differences in survival remain wide notwithstanding public health efforts to improve life expectancy and initiatives to reduce health disparities. Eliminating racial residential segregation and bringing Black socioeconomic status (SES) to White SES levels would eliminate the White-Black survival gap.

Understanding the differences in the incidence and mortality rate between African Americans and whites with CRC remains a perplexing problem. There is clearly not any one factor that explains the observed differences. Clinicians are just beginning to understand the importance of tumor biology, genetics, and lifestyle risk factors in explaining differences in how CRCs present and how they behave. This holds true regardless of a patient's race, sex, or age. Whether these factors will add disproportionately to the understanding of racial differences in presentation and outcome remains to be seen. Certainly, issues surrounding screening for CRC remain important in understanding the advanced stage of presentation for African Americans. In particular, a better understanding is needed of who is being screened and who is not and why. For example, are higher-risk African Americans being screened and if not what are the reasons for this? Importantly, even if one were able to eliminate the differences in stage at presentation between African Americans and whites, a survival disadvantage, albeit a much smaller one, would likely persist. Clearly, there is a need to understand better why African Americans are not receiving recommended therapy at the same rate as whites. This becomes even more important as the life-prolonging options for treating both localized and metastatic colon cancer continue to multiply. Finally, the apparent greater disparity in outcome for African Americans who have stage II disease should be explored in more detail, because this could have an immediate impact on treatment recommendations. For example, a 23-gene signature was recently found to be predictive of recurrence among patients with Dukes B colon cancer [66]. If this model is validated in further studies, one could look at whether African-American patients are more likely to have this predictive signature. The problem has been clearly defined: a higher incidence of and a higher mortality from CRC

Purpose To examine nurses’ self-reported use of race in clinical evaluation. Design This cross-sectional study analyzed data collected from three separate studies using the Genetics and Genomics in Nursing Practice Survey, which includes items about use of race and genomic information in nursing practice. The Racial Attributes in Clinical Evaluation (RACE) scale was used to measure explicit clinical use of race among nurses from across the United States. Methods Multivariate regression analysis was used to examine associations between RACE score and individual-level characteristics and beliefs in 5,733 registered nurses. Findings Analysis revealed significant relationships between RACE score and nurses’ race and ethnicity, educational level, and views on the clinical importance of patient demographic characteristics. Asian nurses reported RACE scores 1.41 points higher than White nurses (p < .001), and Black nurses reported RACE scores 0.55 points higher than White nurses (p < .05). Compared to diploma-level nurses, the baccalaureate-level nurses reported 0.69 points higher RACE scores (p < .05), master’s-level nurses reported 1.63 points higher RACE scores (p < .001), and doctorate-level nurses reported 1.77 points higher RACE scores (p < .01). In terms of clinical importance of patient characteristics, patient race and ethnicity corresponded to a 0.54-point increase in RACE score (p < .001), patient genes to a 0.21-point increase in RACE score (p < .001), patient family history to a 0.15-point increase in RACE score (p < .01), and patient age to a 0.19-point increase in RACE score (p < .001). Conclusions Higher reported use of race among minority nurses may be due, in part, to differential levels of racial self-awareness. A relatively linear positive relationship between level of nursing degree nursing education and use of race suggests that a stronger foundation of knowledge about genetic ancestry, population genetics and the concept “race” and genetic

Poorer recognition of other-race faces relative to own-race faces is well documented from late infancy to adulthood. Research has revealed an increase in the other-race effect (ORE) during the first year of life, but there is some disagreement regarding the age at which it emerges. Using cropped faces to eliminate discrimination based on external features, visual paired comparison and spontaneous visual preference measures were used to investigate the relationship between ORE and face gender at 3-4 and 8-9 months. Caucasian-White 3- to 4-month-olds' discrimination of Chinese, Malay, and Caucasian-White faces showed an own-race advantage for female faces alone whereas at 8-9 months the own-race advantage was general across gender. This developmental effect is accompanied by a preference for female over male faces at 4 months and no gender preference at 9 months. The pattern of recognition advantage and preference suggests that there is a shift from a female-based own-race recognition advantage to a general own-race recognition advantage, in keeping with a visual and social experience-based account of ORE.

Differences in craniofacial anatomy among racial groups have been documented in a variety of structures but the oral and maxillofacial regions have been shown to be a particularly defining region of variability between different racial/ethnic groups. Such comparisons are informative, but they neither address developmental changes of the craniofacial anatomy, nor do they assess or take into account the natural variability within individual races that may account for similar reported, across-group variations. The purpose of this report was to compare – using medical imaging studies – the growth trend of select race sensitive craniofacial variables in the oral and pharyngeal regions when all races: White, Asian, Black, and Hispanic (AR) are included versus only a single race category: White (WR). Race effect was tested by comparing sex specific growth fits (4th degree polynomial model) for AR versus WR data. Findings indicate that the inclusion of all races versus a single race did not significantly alter the growth model fits. Thus, the inclusion of all races permits the advancement of general growth models; however, methodologically it is best to treat the race variable as a covariate in all future analysis to test for both potential all race effects or individual race effects, on general growth models.

Purpose: Although the protective effect of social support against depression is well known, limited information exists on racial differences in this association. The current study examined Black-White differences in the effects of religious and secular emotional social support on depressive symptoms in a national sample of older adults in the United States. Methods: With a longitudinal prospective design, the Religion, Aging and Health Survey, 2001⁻2004, followed 1493 Black ( n = 734) and White ( n = 759) elderly individuals (age 66 and older) for three years. Race, demographics (age and gender), socio-economics (education and marital status) and frequency of church attendance were measured at baseline in 2001. Secular social support, religious social support, chronic medical conditions and depressive symptoms [8- item Center for Epidemiological Studies-Depression scale (CES-D)] were measured in 2004. Multiple linear regression models were used for data analysis. In the pooled sample, secular and religious social support were both protective against depressive symptoms, net of all covariates. Race interacted with secular ( β = −0.62 for interaction) and religious ( β = −0.21 for interaction) social support on baseline depressive symptoms ( p < 0.05 for both interactions), suggesting larger protections for Blacks compared to Whites. In race-specific models, the regression weight for the effect of secular social support on depressive symptoms was larger for Blacks ( β = −0.64) than Whites ( β = −0.16). Conclusion: We found Black—White differences in the protective effects of secular and religious social support against depressive symptoms. Blacks seem to benefit more from the same level of emotional social support, regardless of its source, compared to Whites.

Framing and source effects on White college students' reactions to racial inequity information.

Littleford, Linh Nguyen; Jones, James A

This study addressed: (a) Do professors' race/ethnicity and the race-related inequity information they present influence students' evaluations of the professors, acknowledgment of racial inequity, or motivation to respond without prejudice (MRWP)? (b) Do collective guilt and students' evaluations of professors mediate these relationships? White American undergraduate students (N = 614, 66.3% females, 64.7% first year, mean age of 19.3 years [age SD = 1.5]) completed an anonymous online survey. Students imagined they were taking a racial diversity course with either a Black or a White male professor who presented either White privilege or Black disadvantage statements. Participants then completed surveys that assessed their evaluations of the professor, collective guilt, beliefs regarding racial inequity, and MRWP. Students evaluated White professors as having lower expertise, learning conduciveness, and warmth/intelligence but rated Black professors as more biased. Consistent with the inequality-framing model, intergroup sensitivity effect (ISE), and findings from prejudice confrontation research, White professors induced greater acknowledgment of racial inequity when they discussed White privilege rather than Black disadvantage. But, Black professors induced more external MRWP when they presented White privilege rather than Black disadvantage. Students' perceptions of the professors' warmth/intelligence determined the effectiveness of the inequity message while perceptions of the professors' expertise, judgmental, and conduciveness to learning determined students' concerns about appearing prejudiced. The presenters' race/ethnicity and how they frame racial inequity information affect students' evaluation of the presenters, the message effectiveness, and students' external MRWP.

We examined prevalence of diagnosed autism spectrum disorder (ASD) and age at diagnosis according to child's race/ethnicity and primary household language. From the 2009-2010 National Survey of Children with Special Health Care Needs, we identified 2729 3-17-year-old US children whose parent reported a current ASD diagnosis. We compared ASD prevalence, mean diagnosis age, and percentage with later diagnoses (≥5 years) across racial/ethnic/primary household language groups: non-Hispanic-white, any language (NHW); non-Hispanic-black, any language (NHB); Hispanic-any-race, English (Hispanic-English); and Hispanic-any-race, other language (Hispanic-Other). We assessed findings by parent-reported ASD severity level and adjusted for family sociodemographics. ASD prevalence estimates were 15.3 (NHW), 10.4 (NHB), 14.1 (Hispanic-English), and 5.2 (Hispanic-Other) per 1000 children. Mean diagnosis age was comparable across racial/ethnic/language groups for 3-4-year-olds. For 5-17-year-olds, diagnosis age varied by race/ethnicity/language and also by ASD severity. In this group, NHW children with mild/moderate ASD had a significantly higher proportion (50.8 %) of later diagnoses than NHB (33.5 %) or Hispanic-Other children (18.0 %). However, NHW children with severe ASD had a comparable or lower (albeit non-significant) proportion (16.4 %) of later diagnoses than NHB (37.8 %), Hispanic-English (30.8 %), and Hispanic-Other children (12.0 %). While NHW children have comparable ASD prevalence and diagnosis age distributions as Hispanic-English children, they have both higher prevalence and proportion of later diagnoses than NHB and Hispanic-Other children. The diagnosis age findings were limited to mild/moderate cases only. Thus, the prevalence disparity might be primarily driven by under-representation (potentially under-identification) of older children with mild/moderate ASD in the two minority groups.

To determine the age related patterns of low birth weight (<2,500 g, LBW) and small for gestational age (weight <10th percentile for gestational age, SGA) among former LBW and non-LBW White and African-American mothers. We performed stratified analyses on an Illinois transgenerational dataset of non-Latina White (n = 31,616) and African-American (n = 38,964) infants born in Chicago or Suburban Cook County (1989-1991) and their mothers (1956-1976) with appended US census income information. In both races, LBW and SGA rates were unrelated to age among former LBW 14-35 year old mothers. LBW and SGA rates decreased with advancing age only among former non-LBW White mothers (p < 0.0001). Former non-LBW 30-35 year old White women (n = 11,096) had an infant LBW rate of only 4.3 % compared to 6.8 % for their teen counterparts (n = 1,383), RR (95 % CI) = 0.6 (0.5, 0.8). In contrast, a weathering pattern of rising LBW and SGA rates with advancing age occurred only among former non-LBW African-American mothers (p < 0.0001). Former non-LBW 30-35 year old African-American mothers (N = 4,807) had a LBW rate of 15.0 % compared to 10.8 % for their teen counterparts (N = 8,627), RR (95 % CI) = 1.4 (1.3, 1.5). The same trend occurred among the subgroup of African-American mothers with an early-life and adulthood residence in impoverished neighborhoods. Maternal low birth weight does not contribute to the disparate maternal age related patterns of adverse birth outcome between the races. Moreover, it is not associated with a weathering a pattern of rising rates of LBW with advancing age among African-American mothers with a lifelong residence in impoverished neighborhoods.

Social Relationships and Salivary Telomere Length Among Middle-Aged and Older African American and White Adults.

Lincoln, Karen D; Lloyd, Donald A; Nguyen, Ann W

2017-05-09

A common mechanism underlying premature morbidity may be accelerated biological aging as reflected by salivary telomere length (STL). This study examined the extent to which social relationships, both positive and negative, can be protective or confer risk relative to biological aging. Data from the Health and Retirement Study and multiple regression were used to examine cross-sectional associations between STL, self-reported social support, and negative interaction (e.g., conflict, criticism) with family in a nationally representative sample of African American and non-Hispanic White middle-aged and older adults (N = 4,080). Social support from family was associated with shorter STL. Negative interaction with family had no main effect on STL but interactions characterized by high social support and more frequent negative interactions were associated with longer STL. Negative interaction with family was negatively associated with STL for African Americans and Whites but the magnitude of the effect was greater for African Americans. Study findings highlight the role of social relationships in physiological deterioration among middle-aged and older adults and identify a potential mechanism whereby race is linked to accelerated biological aging. Findings highlight the importance of considering positive and negative aspects of social relationships to understand the consequences of social connections for cellular aging in diverse populations. © The Author 2017.

The home food environment is complex and has the potential to influence dietary habit development in young people. Several factors may influence the home food environment, including income and race/ethnicity. To examine the relationship of income and race/ethnicity with three home food environment factors (ie, food availability frequency, family meal patterns [frequency of family and home cooked meals], and family food expenditures). A cross-sectional analysis of the National Health and Nutrition Examination Survey (NHANES). A total of 5,096 youth aged 6 to 19 years from a nationally representative sample of US individuals participating in NHANES 2007-10. Prevalence of food availability frequency was assessed for the entire sample, race/ethnicity, poverty income ratio (PIR), and race/ethnicity stratified by PIR. Mean values of family meal patterns and food expenditures were calculated based on race/ethnicity, PIR, and race/ethnicity stratified by PIR using analysis of variance and least squares means. Tests of main effects were used to assess differences in food availability prevalence and mean values of family meal patterns and food expenditures. Non-Hispanic whites had the highest prevalence of salty snacks (51.1%±1.5%) and fat-free/low-fat milk (39.2%±1.7%) always available. High-income homes had the highest prevalence of fruits (75.4%±2.4%) and fat-free/low-fat milk (38.4%±2.1%) always available. Differences were found for prevalence of food availability when race/ethnicity was stratified by PIR. Non-Hispanic blacks had the lowest prevalence of fat-free/low-fat milk always available across PIR groups. Differences in mean levels of family meal patterns and food expenditures were found for race/ethnicity, PIR, and race/ethnicity stratified by PIR. Race/ethnicity and PIR appear to influence food availability, family meal patterns, and family food expenditures in homes of youth. Knowledge of factors that influence the home food environment could assist in

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 <500% of poverty) and education (≥college, some college, and ≤high school). African Americans were compared with all others. Adjusting for age and sex, intermediate, but not low, education was associated with approximately 17% lower average waking cortisol and 1% slower decline, compared with high education. Socioeconomic vulnerability was not associated with waking cortisol or linear decline. 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.

Conflicting data exists regarding the influence of population density on colorectal cancer (CRC) outcomes; to better understand this, the present study evaluated outcomes along an urban-rural continuum. Colorectal patients aged ≥40 years from 1992 to 2002 were identified in the SEER (Surveillance, Epidemiology, and End Results) Registries of the National Cancer Institute in the USA. A total of 176 011 patients were identified, with median age 71; most lived in populous counties and were white (90%). Patients from large metropolitan counties were more often African-American, and those in rural counties were more likely to be white and have low socioeconomic status (SES). Patients from large metropolitan (>1 million) and rural counties were more likely to have metastatic disease and decreased survival compared to smaller metropolitan counties (<1 million). Late stage of presentation and diminished survival were also associated with African-American race, male sex and lower SES. Metropolitan counties with populations <1 million had superior CRC outcomes, in part secondary to race and SES.

The Defining Moment: Children's Conceptualization of Race and Experiences with Racial Discrimination.

This paper examines whether children of marginalized racial/ethnic groups have an awareness of race at earlier ages than youth from non-marginalized groups, documents their experiences with racial discrimination, and utilizes a modified racism-related stress model to explore the relationship between perceived racial discrimination and self-esteem. Data were collected for non-Hispanic black, non-Hispanic white, and Hispanic children aged 7 - 12 using face-to-face interviews (n = 175). The concept of race was measured by assessing whether children could define race, if not a standard definition was provided. Racial discrimination was measured using the Williams Every-day-Discrimination Scale, self-esteem was measured using the Rosenberg Scale, and ethnic identity was assessed using the Multi-group Ethnic Identity Measure. Non-Hispanic black children were able to define race more accurately, but overall, Hispanic children encountered more racial discrimination, with frequent reports of ethnic slurs. Additionally, after accounting for ethnic identity, perceived racial discrimination remained a salient stressor that contributed to low self-esteem.

Objectives. We examined sexual orientation differences in adolescent smoking and intersections with race/ethnicity, gender, and age. Methods. We pooled Youth Risk Behavior Survey data collected in 2005 and 2007 from 14 jurisdictions; the analytic sample comprised observations from 13 of those jurisdictions (n = 64 397). We compared smoking behaviors of sexual minorities and heterosexuals on 2 dimensions of sexual orientation: identity (heterosexual, gay–lesbian, bisexual, unsure) and gender of lifetime sexual partners (only opposite sex, only same sex, or both sexes). Multivariable regressions examined whether race/ethnicity, gender, and age modified sexual orientation differences in smoking. Results. Sexual minorities smoked more than heterosexuals. Disparities varied by sexual orientation dimension: they were larger when we compared adolescents by identity rather than gender of sexual partners. In some instances race/ethnicity, gender, and age modified smoking disparities: Black lesbians–gays, Asian American and Pacific Islander lesbians–gays and bisexuals, younger bisexuals, and bisexual girls had greater risk. Conclusions. Sexual orientation, race/ethnicity, gender, and age should be considered in research and practice to better understand and reduce disparities in adolescent smoking. PMID:24825218

As the population ages, the need to characterize rates of cognitive impairment and dementia within demographic groups defined by age, sex, and race becomes increasingly important. There are limited data available on the prevalence and incidence of amnestic mild cognitive impairment (aMCI) and nonamnestic mild cognitive impairment (naMCI) from population-based studies. The Einstein Aging Study, a systematically recruited community-based cohort of 1944 adults aged 70 or older (1168 dementia free at baseline; mean age, 78.8 y; average follow-up, 3.9 y), provides the opportunity to examine the prevalence and incidence rates for dementia, Alzheimer dementia (AD), aMCI, and naMCI by demographic characteristics. Dementia prevalence was 6.5% (4.9% AD). Overall dementia incidence was 2.9/100 person-years (2.3/100 person-years for AD). Dementia and AD rates increased with age but did not differ by sex. Prevalence of aMCI was 11.6%, and naMCI prevalence was 9.9%. aMCI incidence was 3.8 and naMCI incidence was 3.9/100 person-years. Rates of aMCI increased significantly with age in men and in blacks; sex, education, and race were not significant risk factors. In contrast, naMCI incidence did not increase with age; however, blacks were at higher risk compared with whites, even when controlling for sex and education. Results highlight the public health significance of preclinical cognitive disease.

Hypertension and its cardiovascular complications affect African Americans more severely than whites, a disparity variously ascribed to low birth weight, low glomerular number, an exaggerated arteriolonephrosclerotic blood pressure response, and inflammation-induced oxidative stress. Case series. Autopsy kidneys of 107 African Americans and 87 whites aged 18 to 65 years at a single medical center between 1998 and 2005. Excluded were persons with known premorbid kidney disease; pathological findings of severe arterioarteriolonephrosclerosis, nodular and diffuse diabetic glomerulosclerosis, or nonischemic cardiomyopathy. Associations of: (1) race, age, sex, birth weight, obesity, and glomerular number (predictors) with hypertension and death from coronary artery (CAD) and cerebrovascular disease (CVD; outcomes); and (2) age, blood pressure, and race (predictors) with arteriolonephrosclerotic changes, including chronic tubulointerstitial inflammation (outcomes). Hypertension ascertained from chart review and heart weight. Cause of death determined from chart review and autopsy findings. Birth weight obtained from birth records (115 persons). Total glomerular number (N(glom)) estimated by using the dissector/fractionator technique. Arteriolosclerosis, glomerulosclerosis, cortical fibrosis, and chronic inflammation by using CD68 density were measured morphometrically. 59 African Americans (55%) and 32 whites (37%) were classified as hypertensive. CAD and CVD were the cause of death in 64 (33%) and 18 persons (9%), respectively. By using multiple linear regression, birth weight (P < 0.001) and sex (P < 0.01), but not race (P = 0.3) or age (P = 0.2), predicted N(glom) (P < 0.001; adjusted r(2) = 0.176). Hypertension was associated with African American race (P = 0.04), older age (P < 0.001), and male sex (P = 0.01), but not with N(glom) (P = 0.9), body mass index (P = 0.9), or birth weight (P = 0.4). Hypertension was the only significant factor associated with CAD and CVD

BACKGROUND Race differences in the receipt of invasive cardiac procedures are well-documented but the etiology remains poorly understood. OBJECTIVE We examined how social contextual variables were related to race differences in the likelihood of receiving cardiac catheterization in a sample of veterans who were recommended to undergo the procedure by a physician. DESIGN Prospective observational cohort study. PARTICIPANTS A subsample from a study examining race disparities in cardiac catheterization of 48 Black/African American and 189 White veterans who were recommended by a physician to undergo cardiac catheterization. MEASURES We assessed social contextual variables (e.g., knowing somebody who had the procedure, being encouraged by family or friends), clinical variables (e.g., hypertension, maximal medical therapy), and if participants received cardiac catheterization at any point during the study. KEY RESULTS Blacks/African Americans were less likely to undergo cardiac catheterization compared to Whites even after controlling for age, education, and clinical variables (OR = 0.31; 95% CI, 0.13, 0.75). After controlling for demographic and clinical variables, three social contextual variables were significantly related to increased likelihood of receiving catheterization: knowing someone who had undergone the procedure (OR = 3.14; 95% CI, 1.70, 8.74), social support (OR = 2.05; 95% CI, 1.17, 2.78), and being encouraged by family to have procedure (OR = 1.45; 95% CI, 1.08, 1.90). After adding the social contextual variables, race was no longer significantly related to the likelihood of receiving catheterization, thus suggesting that social context plays an important role in the relationship between race and cardiac catheterization. CONCLUSIONS Our results suggest that social contextual factors are related to the likelihood of receiving recommended care. In addition, accounting for these relationships attenuated the observed race disparities between

Our objective was to examine the link between smoking and smoking history, including smoking intensity and cessation, overall and by race, in a biracial prospective cohort study. A subset of Atherosclerosis Risk in Communities Study participants (n = 972, 49% black) completed brain MRI scans twice (1993-1995 and 2004-2006). We defined white matter hyperintensity (WMH) progression as an increase of ≥2 points on the 9-point Cardiovascular Health Study scale across scans. Participants reported information on smoking behavior at the baseline MRI and at 2 prior study visits, approximately 3 and 6 years before baseline. We used adjusted logistic regression to evaluate the association between smoking variables and WMH progression in the total sample and separately by race (black and white). We found WMH progression in 23% of participants (30% of black participants, 17% of white participants). Overall, being a current smoker 6 years before baseline was associated with WMH progression. In race-stratified analyses, we found adverse associations with smoking status at multiple time points and persistent smoking in white but not in black participants. However, we found no statistical support for effect modification by race for most of these analyses. Increasing pack-years of smoking was associated with greater risk of WMH progression, while time since quitting and age at smoking initiation were not associated with WMH progression, with little indication of differences in these associations by race. Our findings concur with previous studies suggesting a relationship between smoking and WMH progression, and further demonstrate a dose-dependent association. © 2015 American Academy of Neurology.

This study examined the relationship between race/ethnicity and psychological resilience, and the moderating role of social support in this relationship among non-Hispanic White (n = 605), Hispanic (n = 107), African American (n = 141), and Asian American (n = 97) Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) combat veterans. Veterans were primarily male (88%) with a mean age of 31.4 years (SD = 8.35). An analysis of covariance showed that Asian American veterans reported significantly lower psychological resilience than non-Hispanic White veterans. The interaction of race/ethnicity and social support with psychological resilience was examined via linear regression. We found that the relationship between psychological resilience and social support significantly differed by race/ethnicity such that social support was positively associated with psychological resilience among non-Hispanic White veterans, but not among other racial/ethnic groups. Our findings are consistent with previous studies that show Asian American veterans report lower psychological resilience than non-Hispanic White veterans. Cultural differences in how and why individuals use social support may underlie racial/ethnic differences in the relationship between social support and psychological resilience. Future qualitative and quantitative research is encouraged to better understand how social support relates to psychological resilience among minority OEF/OIF combat veterans. Copyright © 2018.

Aging is accompanied by a decrease in brain volume and by an increase in cerebrovascular disease. To examine the effects of age, sex, race/ethnicity, and vascular disease history on measures of brain morphology, including relative brain volume, ventricular volume, hippocampus and entorhinal cortex volumes, and white matter hyperintensity (WMH) burden, in a large community-based cohort of racially/ethnically diverse older adults without dementia. The associations of age, sex, race/ethnicity, and self-reported vascular disease history with brain morphology were examined in a cross-sectional study using multiple linear regression analyses. Sex x race/ethnicity interactions were also considered. The Washington Heights-Inwood Columbia Aging Project, a community-based epidemiological study of older adults from 3 racial/ethnic groups (white, Hispanic, and African American) from northern Manhattan. Beginning in 2003, high-resolution quantitative magnetic resonance (MR) images were acquired in 769 participants without dementia. Relative brain volume (total brain volume/intracranial volume), ventricular volume, and hippocampus and entorhinal cortex volumes were derived manually on high-resolution MR images. White matter hyperintensities were quantified semiautomatically on fluid-attenuated inversion recovery-T2-weighted MR images. Older age was associated with decreased relative brain volume and with increased ventricular and WMH volumes. Hispanic and African American participants had larger relative brain volumes and more severe WMH burden than white participants, but the associations of these variables with age were similar across racial/ethnic groups. Compared with men, women had larger relative brain volumes. Vascular disease was associated with smaller relative brain volume and with higher WMH burden, particularly among African Americans. Older age and vascular disease, particularly among African Americans, are associated with increased brain atrophy and WMH burden

Food insecurity and adult overweight/obesity: Gender and race/ethnic disparities.

The majority of the food insecurity-obesity research has indicated a positive association among women, especially minority women. Less research has been conducted on men, and the findings are inconsistent. The aim was to assess whether gender and race/ethnic disparities exists between the food insecurity and overweight/obesity relationship among adults ages 18-59. We used the cross-sectional 2011 and 2012 National Health Interview Survey data (N = 19,990). Three or more affirmative responses on the 10-item USDA Food Security Scale indicated food insecure experiences. Self-reported height and weight were used to calculate body mass index according to the Centers for Disease Control and Prevention. Multivariate logistic regression models were stratified by gender and race/ethnicity to estimate the association between food insecurity and overweight/obesity controlling for several demographic characteristics. Adults on average were 36 years of age (51% female; 56% white, 27% Hispanic, and 17% black), 27% were food insecure, and 65% were overweight/obese. Food insecurity was most prevalent among blacks and Hispanics, regardless of gender. A greater percentage of food insecure women were overweight/obese compared to food secure women among all race/ethnicity groups; while similar proportions of white, black, and Hispanic men were overweight/obese irrespective of their food security status. In covariate-adjusted models, food insecurity was associated with a 41% and 29% higher odds of being overweight/obese among white and Hispanic women, respectively. Food insecurity was not related to overweight/obesity among black women nor among white, black, and Hispanic men. The complex relationship between food insecurity and obesity suggests a need to investigate potential behavioral and physiological mechanisms, and moderators of this relationship.

To describe the prevalence of multimorbidity involving 20 selected chronic conditions in a geographically defined US population, emphasizing age, sex, and racial/ethnic differences. Using the Rochester Epidemiology Project records linkage system, we identified all residents of Olmsted County, Minnesota, on April 1, 2010, and electronically extracted the International Classification of Diseases, Ninth Revision codes associated with all health care visits made between April 1, 2005, and March 31, 2010 (5-year capture frame). Using these codes, we defined the 20 common chronic conditions recommended by the US Department of Health and Human Services. We counted only persons who received at least 2 codes for a given condition separated by more than 30 days, and we calculated the age-, sex-, and race/ethnicity-specific prevalence of multimorbidity. Of the 138,858 study participants, 52.4% were women (n=72,732) and 38.9% had 1 or more conditions (n=54,012), 22.6% had 2 or more conditions (n=31,444), and 4.9% had 5 or more conditions (n=6853). The prevalence of multimorbidity (≥2 conditions) increased steeply with older age and reached 77.3% at 65 years and older. However, the absolute number of people affected by multimorbidity was higher in those younger than 65 years. Although the prevalence of multimorbidity was similar in men and women overall, the most common dyads and triads of conditions varied by sex. Compared with white persons, the prevalence of multimorbidity was slightly higher in black persons and slightly lower in Asian persons. Multimorbidity is common in the general population; it increases steeply with older age, has different patterns in men and women, and varies by race/ethnicity.

Background Low socioeconomic status (SES) and African American race are both independently associated with end-stage renal disease and progressive chronic kidney disease (CKD), however, despite their frequent co-occurrence, the effect of low SES independent of race has not been well-studied in CKD. Study Design Cross-sectional study. Setting & Participants 2,375 community-dwelling adults age 30-64 years residing within 12 neighborhoods selected for both socioeconomic and racial diversity in Baltimore City, Maryland. Predictors Low SES [self-reported household income <125% of 2004 Department of Health and Human Services guideline], higher SES (≥125% of guideline); white and African American race. Outcomes & Measurements CKD defined as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2. Logistic regression used to calculate odds ratios (OR) for relationship between poverty and CKD, stratified by race. Results Of 2,375 participants; 955 were white (347 low SES and 608 higher SES); 1,420 were African American (713 low SES and 707 higher SES). A total of 146 (6.2%) participants had CKD. Overall, race was not associated with CKD [OR, 1.05; 95% confidence interval (CI), 0.57-1.96]; however, African Americans had a much greater odds of advanced CKD (eGFR <30 mL/min/1.73 m2). Low SES was independently associated with 59% greater odds of CKD after adjustment for demographics, insurance status and comorbid disease (OR, 1.59; 95% CI, 1.27-1.99). However, when stratified by race, low SES was associated with CKD in African Americans (OR, 1.91; 95% CI, 1.54-2.38), but not in whites (OR, 0.95; 95% CI, 0.58-1.55; P for interaction, 0.003). Limitations Cross-sectional design; findings may not be generalizable to non-urban populations. Conclusions Low SES has a profound relationship with CKD in African Americans but not in whites in an urban population of adults, and its role in the racial disparities seen in CKD is worthy of further investigation.

To examine race and ethnic differences in the importance of obesity for social integration using the National Longitudinal Study of Adolescent Health (Add Health). A cross-sectional study utilizing survey-adjusted statistics and multivariate logistic and linear regression models. Models were stratified by sex and included interaction terms capturing race, ethnicity and obesity. United States of America. A nationally representative sample of 15,355 respondents grades 7 through 12 who participated in both the In-School and In-Home Wave I surveys of Add Health. Four self-reported and schoolmate-reported indicators of social integration. The consequences of obesity for social integration are greatest for White adolescents, who were selected by almost 2 fewer schoolmates as friends and had half the odds of having their friendships reciprocated compared with non-obese White adolescents. The social disadvantage of obesity was lower for non-White adolescents; though they are selected by significantly fewer schoolmates as friends and were less likely to have their friendships reciprocated, they did not face additional discrimination from being both obese and minority. There are significant differences between obese and non-obese adolescents by race and ethnicity in friendships. As friendships are among the most valued assets in adolescence, understanding the impact of obesity on access to friendships for diverse adolescents is a necessary component to understanding the complex motivations that guide health-related behavior at these formative ages.

Background Patients are being encouraged to go online to obtain health information and interact with their health care systems. However, a 2014 survey found that less than 60% of American adults aged 65 and older use the Internet, with much lower usage among black and Latino seniors compared with non-Hispanic white seniors, and among older versus younger seniors. Objective Our aims were to (1) identify race/ethnic and age cohort disparities among seniors in use of the health plan’s patient portal, (2) determine whether race/ethnic and age cohort disparities exist in access to digital devices and preferences for using email- and Web-based modalities to interact with the health care system, (3) assess whether observed disparities in preferences and patient portal use are due simply to barriers to access and inability to use the Internet, and (4) learn whether older adults not currently using the health plan’s patient portal or website have a potential interest in doing so in the future and what kind of support might be best suited to help them. Methods We conducted two studies of seniors aged 65-79 years. First, we used administrative data about patient portal account status and utilization in 2013 for a large cohort of English-speaking non-Hispanic white (n=183,565), black (n=16,898), Latino (n=12,409), Filipino (n=11,896), and Chinese (n=6314) members of the Kaiser Permanente Northern California health plan. Second, we used data from a mailed survey conducted in 2013-2014 with a stratified random sample of this population (final sample: 849 non-Hispanic white, 567 black, 653 Latino, 219 Filipino, and 314 Chinese). These data were used to examine race/ethnic and age disparities in patient portal use and readiness and preferences for using digital communication for health-related purposes. Results Adults aged 70-74 and 75-79 were significantly less likely than 65-69 year olds to be registered to use the patient portal, and among those registered, to have used the

Using archival data, we conducted a secondary analysis to examine race-differences in the relation of serum vitamins A, C, E and β-carotene to insulin resistance (IR), fasting insulin and glucose, high sensitivity C-reactive protein (hsCRP), and leukocyte count in 176 non-smoking, healthy, white and African American (AA) adults aged 18-65 years (48% women, 33% AA). We hypothesized that micronutrient concentrations would be associated with early risk markers of cardiometabolic diseases in a race-dependent manner. Fasting blood samples were analyzed for micronutrients, insulin, glucose, hsCRP, and leukocyte count. Insulin resistance was estimated using the homeostatic model assessment (HOMA). After adjusting for age, body mass index, gender, educational level, use of vitamin supplements, alcohol intake, leisure time physical activity, menopausal status, and total cholesterol, we observed that β-carotene was significantly associated with insulin resistance and fasting insulin in a race-dependent manner. Among AA, lower β-carotene levels were associated with higher estimates of insulin resistance and fasting insulin; whereas, these same associations were not significant for whites. Race also significantly moderated the relation of vitamin C to leukocyte count, with lower vitamin C being associated with higher leukocyte count only in AA but not whites. For all subjects, lower β-carotene was associated with higher hsCRP. In AA, but not whites, lower levels of β-carotene and vitamin C were significantly associated with early risk markers implicated in cardiometabolic conditions and cancer. Whether or not lower levels of micronutrients contribute uniquely to racial health disparities is a worthwhile aim for future research. PMID:24418240

Grandfather caregivers: race and ethnic differences in poverty.

Keene, Jennifer R; Prokos, Anastasia H; Held, Barbara

2012-01-01

We use data from the 2006 American Community Survey to examine race and ethnic differences in the effects of marital status and co-residence of the middle generation on the likelihood of poverty among grandfathers who have primary responsibility for co-resident grandchildren (N = 3,379). Logistic regression results indicate that race/ethnicity and household composition are significant predictors of poverty for grandfather caregivers: non-Hispanic white grandfathers, those who are married, and those with a co-resident middle generation are the least likely to be poor. The effects of race/ethnicity, marital status, and the presence of a middle generation are, however, contingent upon one another. Specifically, the negative effect of being married is lower among grandfathers who are Hispanic, African American, non-Hispanic, and non-Hispanics of other race/ethnic groups compared to whites. In addition, having a middle generation in the home has a larger negative effect on poverty for race/ethnic minority grandfathers than for non-Hispanic whites. Finally, the combined effects of marriage and a middle generation vary across race/ethnic group and are associated with lower chances of poverty among some groups compared with others. We use the theory of cumulative disadvantage to interpret these findings and suggest that race/ethnicity and household composition are synergistically related to economic resources for grandfather caregivers.

Positive and Negative Affect More Concurrent among Blacks than Whites.

While positive and negative affect are inversely linked, people may experience and report both positive and negative emotions simultaneously. However, it is unknown if race alters the magnitude of the association between positive and negative affect. The current study compared Black and White Americans for the association between positive and negative affect. We used data from MIDUS (Midlife in the United States), a national study of Americans with an age range of 25 to 75. A total number of 7108 individuals were followed for 10 years from 1995 to 2004. Positive and negative affect was measured at baseline (1995) and follow-up (2004). Demographic (age and gender), socioeconomic (education and income) as well as health (self-rated health, chronic medical conditions, and body mass index) factors measured at baseline were covariates. A series of linear regressions were used to test the moderating effect of race on the reciprocal association between positive and negative affect at baseline and over time, net of covariates. In the pooled sample, positive and negative affect showed inverse correlation at baseline and over time, net of covariates. Blacks and Whites differed in the magnitude of the association between positive and negative affect, with weaker inverse associations among Blacks compared to Whites, beyond all covariates. Weaker reciprocal association between positive and negative affect in Blacks compared to Whites has implications for cross-racial measurement of affect and mood, including depression. Depression screening programs should be aware that race alters the concordance between positive and negative affect domains and that Blacks endorse higher levels of positive affect compared to Whites in the presence of high negative affect.

Variations in Social Network Type Membership Among Older African Americans, Caribbean Blacks, and Non-Hispanic Whites

PubMed Central

2017-01-01

Abstract Objectives: This study examined race differences in the probability of belonging to a specific social network typology of family, friends, and church members. Method: Samples of African Americans, Caribbean blacks, and non-Hispanic whites aged 55+ were drawn from the National Survey of American Life. Typology indicators related to social integration and negative interactions with family, friendship, and church networks were used. Latent class analysis was used to identify typologies, and latent class multinomial logistic regression was used to assess the influence of race, and interactions between race and age, and race and education on typology membership. Results: Four network typologies were identified: optimal (high social integration, low negative interaction), family-centered (high social integration within primarily the extended family network, low negative interaction), strained (low social integration, high negative interaction), and ambivalent (high social integration and high negative interaction). Findings for race and age and race and education interactions indicated that the effects of education and age on typology membership varied by race. Discussion: Overall, the findings demonstrate how race interacts with age and education to influence the probability of belonging to particular network types. A better understanding of the influence of race, education, and age on social network typologies will inform future research and theoretical developments in this area. PMID:28329871

We sought to determine the role of neighborhood poverty and racial composition on race disparities in diabetes prevalence. We used data from the 1999-2004 National Health and Nutrition Examination Survey and 2000 US Census to estimate the impact of individual race and poverty and neighborhood racial composition and poverty concentration on the odds of having diabetes. We found a race-poverty-place gradient for diabetes prevalence for Blacks and poor Whites. The odds of having diabetes were higher for Blacks than for Whites. Individual poverty increased the odds of having diabetes for both Whites and Blacks. Living in a poor neighborhood increased the odds of having diabetes for Blacks and poor Whites. To address race disparities in diabetes, policymakers should address problems created by concentrated poverty (e.g., lack of access to reasonably priced fruits and vegetables, recreational facilities, and health care services; high crime rates; and greater exposures to environmental toxins). Housing and development policies in urban areas should avoid creating high-poverty neighborhoods.

Whites but Not Blacks Gain Life Expectancy from Social Contacts.

Assari, Shervin

2017-10-16

Background . Recent research suggests that the health gain from economic resources and psychological assets may be systematically larger for Whites than Blacks. Aim . This study aimed to assess whether the life expectancy gain associated with social contacts over a long follow up differs for Blacks and Whites. Methods . Data came from the Americans' Changing Lives (ACL) Study, 1986-2011. The sample was a nationally representative sample of American adults 25 and older, who were followed for up to 25 years ( n = 3361). Outcome was all-cause mortality. The main predictor was social contacts defined as number of regular visits with friends, relatives, and neighbors. Baseline demographics (age and gender), socioeconomic status (education, income, and employment), health behaviors (smoking and drinking), and health (chronic medical conditions, obesity, and depressive symptoms) were controlled. Race was the focal moderator. Cox proportional hazard models were used in the pooled sample and based on race. Results . More social contacts predicted higher life expectancy in the pooled sample. A significant interaction was found between race and social contacts, suggesting that the protective effect of more social contacts is smaller for Blacks than Whites. In stratified models, more social contacts predicted an increased life expectancy for Whites but not Blacks. Conclusion . Social contacts increase life expectancy for White but not Black Americans. This study introduces social contacts as another social resource that differentially affects health of Whites and Blacks.

On the failure to notice that White people are White: Generating and testing hypotheses in the celebrity guessing game.

PubMed

Hegarty, Peter

2017-01-01

Drawing together social psychologists' concerns with equality and cognitive psychologists' concerns with scientific inference, 6 studies (N = 841) showed how implicit category norms make the generation and test of hypothesis about race highly asymmetric. Having shown that Whiteness is the default race of celebrity actors (Study 1), Study 2 used a variant of Wason's (1960) rule discovery task to demonstrate greater difficulty in discovering rules that require specifying that race is shared by White celebrity actors than by Black celebrity actors. Clues to the Whiteness of White actors from analogous problems had little effect on hypothesis formation or rule discovery (Studies 3 and 4). Rather, across Studies 2 and 4 feedback about negative cases-non-White celebrities-facilitated the discovery that White actors shared a race, whether participants or experimenters generated the negative cases. These category norms were little affected by making White actors' Whiteness more informative (Study 5). Although participants understood that discovering that White actors are White would be harder than discovering that Black actors are Black, they showed limited insight into the information contained in negative cases (Study 6). Category norms render some identities as implicit defaults, making hypothesis formation and generalization about real social groups asymmetric in ways that have implications for scientific reasoning and social equality.

Autism spectrum disorder (ASD) is typified as a brain connectivity disorder in which white matter abnormalities are already present early on in life. However, it is unknown if and to which extent these abnormalities are hard-wired in (older) adults with ASD and how this interacts with age-related white matter changes as observed in typical aging. The aim of this first cross-sectional study in mid- and late-aged adults with ASD was to characterize white matter microstructure and its relationship with age. We utilized diffusion tensor imaging with head motion control in 48 adults with ASD and 48 age-matched controls (30-74 years), who also completed a Flanker task. Intra-individual variability of reaction times (IIVRT) measures based on performance on the Flanker interference task were used to assess IIVRT-white matter microstructure associations. We observed primarily higher mean and radial diffusivity in white matter microstructure in ASD, particularly in long-range fibers, which persisted after taking head motion into account. Importantly, group-by-age interactions revealed higher age-related mean and radial diffusivity in ASD, in projection and association fiber tracts. Subtle dissociations were observed in IIVRT-white matter microstructure relations between groups, with the IIVRT-white matter association pattern in ASD resembling observations in cognitive aging. The observed white matter microstructure differences are lending support to the structural underconnectivity hypothesis in ASD. These reductions seem to have behavioral percussions given the atypical relationship with IIVRT. Taken together, the current results may indicate different age-related patterns of white matter microstructure in adults with ASD.

Completion of prescribed neoadjuvant chemotherapy for breast cancer is paramount to patients obtaining full benefit from the treatment; however, factors affecting neoadjuvant chemotherapy completion are not known. We hypothesized that race is a predictor of completion of neoadjuvant chemotherapy in patients with breast cancer. All patients with breast cancer treated with neoadjuvant chemotherapy 2009-2016 at a single institution were stratified by completion of neoadjuvant chemotherapy and by race. Univariate analysis and multivariable logistic regression were used to identify patient and tumor characteristics that affected the rate of neoadjuvant chemotherapy completion. A total of 92 (74%) of 124 patients completed their prescribed neoadjuvant chemotherapy. On univariate analysis, white patients were more likely to complete neoadjuvant chemotherapy than non-white patients (76% vs 50%, P = .006). Non-white patients were more likely to have government insurance and larger prechemotherapy tumors (both, P < .05), but these factors were not associated with rates of neoadjuvant chemotherapy completion. After controlling for age, insurance status, tumor size, and estrogen receptor status, whites remained associated with completion of neoadjuvant chemotherapy (OR 3.65, P = .014). At our institution, white patients with breast cancer were more likely than non-white patients to complete neoadjuvant chemotherapy. Further investigation into the underlying factors impacting this disparity is needed. Copyright © 2018 Elsevier Inc. All rights reserved.

Aging is known to have deleterious effects on cerebral white matter, yet little is known about these white matter alterations in advanced age. In this study, 94 oldest-old adults without dementia (90-103 years) underwent diffusion tensor imaging to assess relationships between chronological age and multiple measures of integrity in 18 white matter regions across the brain. Results revealed significant age-related declines in integrity in regions previously identified as being sensitive to aging in younger-old adults (corpus callosum, fornix, cingulum, external capsule). For the corpus callosum, the effect of age on genu fractional anisotropy was significantly weaker than the relationship between age and splenium fractional anisotropy. Importantly, age-related declines in white matter integrity did not differ in cognitively normal and cognitively impaired not demented oldest-old, suggesting that they were not solely driven by cognitive dysfunction or preclinical dementia in this advanced age group. Instead, white matter in these regions appears to remain vulnerable to normal aging processes through the 10th decade of life. Copyright © 2017 Elsevier Inc. All rights reserved.

This paper examines body mass index (BMI) trajectories among children from different race/ethnic and maternal nativity backgrounds in the United States and England from early- to middle-childhood. This study is the first to examine race/ethnic and maternal nativity differences in BMI trajectories in both countries. We use two longitudinal birth cohort studies-The Fragile Families and Child Wellbeing Study (n = 3,285) for the United States and the Millennium Cohort Study (n = 6,700) for England to estimate trajectories in child BMI by race/ethnicity and maternal nativity status using multilevel growth models. In the United States our sample includes white, black, and Hispanic children; in England the sample includes white, black, and Asian children. We find significant race/ethnic differences in the initial BMI and BMI trajectories of children in both countries, with all non-white groups having significantly steeper BMI growth trajectories than whites. Nativity differences in BMI trajectories vary by race/ethnic group and are only statistically significantly higher for children of foreign-born blacks in England. Disparities in BMI trajectories are pervasive in the United States and England, despite lower overall BMI among English children. Future studies should consider both race/ethnicity and maternal nativity status subgroups when examining disparities in BMI in the United States and England. Differences in BMI are apparent in early childhood, which suggests that interventions targeting pre-school age children may be most effective at stemming childhood disparities in BMI.

The cross-race effect in face recognition memory by bicultural individuals.

Social-cognitive models of the cross-race effect (CRE) generally specify that cross-race faces are automatically categorized as an out-group, and that different encoding processes are then applied to same-race and cross-race faces, resulting in better recognition memory for same-race faces. We examined whether cultural priming moderates the cognitive categorization of cross-race faces. In Experiment 1, monoracial Latino-Americans, considered to have a bicultural self, were primed to focus on either a Latino or American cultural self and then viewed Latino and White faces. Latino-Americans primed as Latino exhibited higher recognition accuracy (A') for Latino than White faces; those primed as American exhibited higher recognition accuracy for White than Latino faces. In Experiment 2, as predicted, prime condition did not moderate the CRE in European-Americans. These results suggest that for monoracial biculturals, priming either of their cultural identities influences the encoding processes applied to same- and cross-race faces, thereby moderating the CRE.

Chronic neuroinflammation, which is primarily mediated by microglia, plays an essential role in aging and neurodegeneration. It is still unclear whether this microglia-induced neuroinflammation occurs globally or is confined to distinct brain regions. In this study, we investigated microglia activity in various brain regions upon healthy aging and Alzheimer's disease (AD)-related pathology in both human and mouse samples. In purified microglia isolated from aging mouse brains, we found a profound gene expression pattern related to pro-inflammatory processes, phagocytosis, and lipid homeostasis. Particularly in white matter microglia of 24-month-old mice, abundant expression of phagocytic markers including Mac-2, Axl, CD16/32, Dectin1, CD11c, and CD36 was detected. Interestingly, in white matter of human brain tissue the first signs of inflammatory activity were already detected during middle age. Thus quantification of microglial proteins, such as CD68 (commonly associated with phagocytosis) and HLA-DR (associated with antigen presentation), in postmortem human white matter brain tissue showed an age-dependent increase in immunoreactivity already in middle-aged people (53.2 ± 2.0 years). This early inflammation was also detectable by non-invasive positron emission tomography imaging using [ 11 C]-(R)-PK11195, a ligand that binds to activated microglia. Increased microglia activity was also prominently present in the white matter of human postmortem early-onset AD (EOAD) brain tissue. Interestingly, microglia activity in the white matter of late-onset AD (LOAD) CNS was similar to that of the aged clinically silent AD cases. These data indicate that microglia-induced neuroinflammation is predominant in the white matter of aging mice and humans as well as in EOAD brains. This white matter inflammation may contribute to the progression of neurodegeneration, and have prognostic value for detecting the onset and progression of aging and neurodegeneration.

We considered changes in the geographic distribution of early stage breast cancer among White and non-White women while secular trends in lifestyle and health care were under way. We aggregated tumor registry and census data by age, race, place of residence, and year of diagnosis to evaluate rate variation across Connecticut census tracts between 1985 and 2009. Global and local cluster detection tests were completed. Age-adjusted incidence rates increased by 2.71% and 0.44% per year for White and non-White women, respectively. Significant global clustering was identified during surveillance of these populations, but the elements of clustering differed between groups. Among White women, fewer local clusters were detected after 1985 to 1989, whereas clustering increased over time among non-White women. Small-area variation of breast cancer incidence rates across time periods proved to be dynamic and race-specific. Incidence rates might have been affected by secular trends in lifestyle or health care. Single cross-sectional analyses might have confused our understanding of disease occurrence by not accounting for the social context in which patient preferences or provider capacity influence the numbers and locations of diagnosed cases. Serial analyses are recommended to identify "hot spots" where persistent geographic disparities in incidence occur.

The purpose of this study was to examine, among the general public, the independent effect of race on women's use of health information resources. A population-based random-digit dialing survey of adult women, aged 18 to 64 years, was conducted between October 1999 and January 2000. Subjects included 509 women (341 white women, 135 black women, and 33 women of other races). The response rate was 66%. The main outcome variable was the use of health information resources (print health or news media, broadcast media, computer resources [Internet], health organizations, organized health events). Logistic regression was used to determine the independent effect of race/ethnicity on the use of different information resources, with an adjustment for age, income, education, and marital status. After the adjustment for socioeconomic factors, black women had <50% odds of using print news media (odds ratio, 0.5; 95% CI, 0.4-0.8), <60% odds of using computer-based resources (odds ratio, 0.4; 95% CI, 0.2-0.6), and <70% odds of using health policy organizations (odds ratio, 0.3; 95% CI, 0.2-0.7), compared with white women. There is a large racial disparity in women's use of health information resources. Traditional sources that are used to provide patient information may not be effective in certain populations.

Distinguishing the race-specific effects of income inequality and mortality in U.S. metropolitan areas.

In the United States, the association between income inequality and mortality has been fairly consistent. However, few studies have explicitly examined the impact of race. Studies that have either stratified outcomes by race or conducted analyses within race-specific groups suggest that the income inequality/mortality relation may differ for blacks and whites. The factors explaining the association may also differ for the two groups. Multivariate ordinary least squares regression analysis was used to examine associations between study variables. We used three measures of income inequality to examine the association between income inequality and age-adjusted all-cause mortality among blacks and whites separately. We also examined the role of racial residential segregation and concentrated poverty in explaining associations among groups. Metropolitan areas were included if they had a population of at least 100,000 and were at least 10 percent black. There was a positive income inequality/mortality association among blacks and an inverse association among whites. Racial residential segregation completely attenuated the income inequality/mortality relationship for blacks, but was not significant among whites. Concentrated poverty was a significant predictor of mortality rates in both groups but did not confound associations. The implications of these findings and directions for future research are discussed.

Abstract Experience suggests that African Americans may express autoimmune disease differently than other racial groups. In the context of systemic sclerosis (scleroderma), we sought to determine whether race was related to a more adverse expression of disease. Between January 1, 1990, and December 31, 2009, a total of 409 African American and 1808 white patients with scleroderma were evaluated at a single university medical center. While the distribution by sex was virtually identical in both groups, at 82% female, African American patients presented to the center at a younger mean age than white patients (47 vs. 53 yr; p < 0.001). Two-thirds of white patients manifested the limited cutaneous subset of disease, whereas the majority of African American patients manifested the diffuse cutaneous subset (p < 0.001). The proportion seropositive for anticentromere antibody was nearly 3-fold greater among white patients, at 34%, compared to African American patients (12%; p < 0.001). Nearly a third of African American (31%) patients had autoantibodies to topoisomerase, compared to 19% of white patients (p = 0.001). Notably, African American patients experienced an increase in prevalence of cardiac (adjusted odds ratio [OR], 1.6; 95% confidence interval [CI], 1.3–2.2), renal (OR, 1.6; 95% CI, 1.2–2.1), digital ischemia (OR, 1.5; 95% CI, 1.4–2.2), muscle (OR, 1.7; 95% CI, 1.3–2.3), and restrictive lung (OR, 6.9; 95% CI, 5.1–9.4) disease. Overall, 700 (32%) patients died (159 African American; 541 white). The cumulative incidence of mortality at 10 years was 43% among African American patients compared to 35% among white patients (log-rank p = 0.0011). Compared to white patients, African American patients experienced an 80% increase in risk of mortality (relative risk [RR], 1.8; 95% CI, 1.4–2.2), after adjustment for age at disease onset and disease duration.

White Dwarfs in Wide Binaries and the Age of the Galaxy

NASA Astrophysics Data System (ADS)

Smith, John Allyn

A comprehensive study of common proper binary systems suspected of containing white dwarf stars is being conducted by Oswalt and collaborators (Oswalt et al. 1988). These systems usually contain a white dwarf and a main sequence star. In the present study, we use the white dwarf luminosity function to determine the age of the local Galactic disk as well as the local space density of white dwarfs. We obtained BVRI photometry of approximately 475 systems (of 512) which were found to contain about 325 white dwarfs. Of these white dwarfs, 152 met the selection criteria for our study and were used in the final analysis. Using this largest sample of cool white dwarfs in binary systems observed to date, we have determined an age for the Galactic disk of 9.7-0.8+0.9 Gyr which yields a lower limit age for the Universe of about 11.7 Gyr. Recent globular cluster studies agree to within ±1σ for the Galaxy age derived from our Disk age. The latest cosmologically derived age for the Universe, modified for the recently released Hipparcos data, is now in accordance with our age estimates for the Universe, for H o (69 km s-1 Mpc-1) and an inflationary cosmology. Further, our age is in accord with the ages derived for the Galaxy from nucleocomsochronology and meteoritic sample analyses. As a part of this work, we have determined the white dwarf space density to be 4.5 ± 1.0 10-3 pc-3, in accord with the results previously reported by Liebert, Dahn & Monet (1987). This space density corresponds to a white dwarf birthrate of 4.65 × 10-13 yr-1 pc-3. This research also details a unique approach to calculating and correcting for the incompleteness of a proper motion and magnitude selected stellar sample.

We investigated effects of defendant race, victim race, and juror gender on public perceptions of a juvenile sex offense. We predicted that participants, particularly men, would support registering a juvenile defendant as a sex offender more when he was Black than White and that participants, particularly women, would support registering the defendant more when the female crime victim was portrayed as White than as Black. We also expected that support for registration would be higher when the defendant and victim were different races than when they were the same race. As expected, women (but not men) recommended registration more when the victim was White than Black. Further, participants supported registration more when the defendant and the victim were different races than when they were the same race. These effects were mediated by retributive goals to punish the offender-not by utilitarian goals to protect society. Explanations and implications are discussed.

Does race matter in neighborhood preferences? Results from a video experiment.

Persistent racial residential segregation is often seen as the result of preferences: whites prefer to live with whites while blacks wish to live near many other blacks. Are these neighborhood preferences color-blind or race conscious? Does neighborhood racial composition have a net influence upon preferences, or is race a proxy for social class? This article tests the racial proxy hypothesis using an innovative experiment that isolates the net effects of race and social class, followed by an analysis of the social psychological factors associated with residential preferences. The authors find that net of social class, the race of a neighborhood's residents significantly influenced how it was rated. Whites said the all-white neighborhoods were most desirable. The independent effect of racial composition was smaller among blacks, who identified the racially mixed neighborhood as most desirable. Further, whites who held negative stereotypes about African-Americans and the neighborhoods where they live were significantly influenced by neighborhood racial composition. None of the proposed social psychological factors conditioned African-Americans' sensitivity to neighborhood racial composition.

This study examined how adiposity influences racial/ethnic differences in diabetes incidence by exploring whether relations between anthropometric measures and incident diabetes vary by race/ethnicity. Data from the Multi-Ethnic Study of Atherosclerosis initiated in 2000 (n = 5,446 US men and women aged 45–84 years) were analyzed by using proportional hazards and Poisson regression. The diabetes incidence rate was 2/100 person-years (n = 479 cases). Interactions were present between race and anthropometry (P-interaction(race × body mass index) = 0.002). The slope of incident diabetes per anthropometric unit was greatest for Chinese, less for whites and Hispanics, and still less for blacks. For small waist, risk of incident diabetes was <1/100 person-years for all racial/ethnic groups. At intermediate waist levels, Chinese had the highest and whites the lowest rates of incident diabetes. At the respective 95th percentiles of waist circumference, risk of incident diabetes per 100 person-years was 3.9 for Chinese (104 cm), 3.5 for whites (121 cm), 5.0 for blacks (125 cm), and 5.3 for Hispanics (121 cm). Adiposity influenced relative diabetes occurrence across racial/ethnic groups, in that Chinese had a steeper diabetes risk per unit of adiposity. However, the generally low level of adiposity in Chinese led to a relatively low diabetes occurrence. PMID:20570825

We sought to build models that address questions of interest to patients and families by predicting short- and long-term mortality and functional outcome after ischemic stroke, while allowing for risk restratification as comorbid events accumulate. A cohort of 451 ischemic stroke subjects in 1999 were interviewed during hospitalization, at 3 months, and at approximately 4 years. Medical records from the acute hospitalization were abstracted. All hospitalizations for 3 months poststroke were reviewed to ascertain medical and psychiatric comorbidities, which were categorized for analysis. Multivariable models were derived to predict mortality and functional outcome (modified Rankin Scale) at 3 months and 4 years. Comorbidities were included as modifiers of the 3-month models, and included in 4-year predictions. Poststroke medical and psychiatric comorbidities significantly increased short-term poststroke mortality and morbidity. Severe periventricular white matter disease (PVWMD) was significantly associated with poor functional outcome at 3 months, independent of other factors, such as diabetes and age; inclusion of this imaging variable eliminated other traditional risk factors often found in stroke outcomes models. Outcome at 3 months was a significant predictor of long-term mortality and functional outcome. Black race was a predictor of 4-year mortality. We propose that predictive models for stroke outcome, as well as analysis of clinical trials, should include adjustment for comorbid conditions. The effects of PVWMD on short-term functional outcomes and black race on long-term mortality are findings that require confirmation.

We evaluated whether differences in cardiovascular risk factors, as assessed by the Framingham risk scores for stroke and cardiovascular disease (FSRS and FCRS), contributed to disparities in all-cause mortality across race and regional strata of USA. Race-region-specific FSRS and FCRS scores were computed for 30,086 REGARDS participants who were recruited between January 2003 and October 2007. They were divided across six regions of the "Eight Americas" and then compared after adjusting for race and sex. Kaplan-Meier curves and hazard ratios for all-cause mortality were estimated between regions, first adjusted for age and sex, and then for the risk scores. After adjustment for age, sex, FCRS, and FSRS, there was no difference in mortality among Middle-America Whites versus Low-Income White. However, mortality was lower among Middle-America Blacks (-23 %; p = 0.06) and High-Risk Urban Blacks (-24 %; p = 0.01) compared to Southern Low-Income Rural Blacks. Compared to Middle-American Whites, mortality was higher among Middle-America Blacks (+39 %; p < 0.001), High-Risk Urban Blacks (+35 %; p < 0.001) and Southern Low-Income Rural Blacks (+85 %; p < 0.001). Accounting for cardiovascular risk unmasked a greater disparity in mortality between Blacks and Whites and among Southern Rural Blacks compared to Middle-America Blacks and High-Risk Urban Blacks.

This paper examines whether children of marginalized racial/ethnic groups have an awareness of race at earlier ages than youth from non-marginalized groups, documents their experiences with racial discrimination, and utilizes a modified racism-related stress model to explore the relationship between perceived racial discrimination and self-esteem. Data were collected for non-Hispanic black, non-Hispanic white, and Hispanic children aged 7 – 12 using face-to-face interviews (n = 175). The concept of race was measured by assessing whether children could define race, if not a standard definition was provided. Racial discrimination was measured using the Williams Every-day-Discrimination Scale, self-esteem was measured using the Rosenberg Scale, and ethnic identity was assessed using the Multi-group Ethnic Identity Measure. Non-Hispanic black children were able to define race more accurately, but overall, Hispanic children encountered more racial discrimination, with frequent reports of ethnic slurs. Additionally, after accounting for ethnic identity, perceived racial discrimination remained a salient stressor that contributed to low self-esteem. PMID:21532908

White matter changes and word finding failures with increasing age.

Increasing life expectancy necessitates the better understanding of the neurophysiological underpinnings of age-related cognitive changes. The majority of research examining structural-cognitive relationships in aging focuses on the role of age-related changes to grey matter integrity. In the current study, we examined the relationship between age-related changes in white matter and language production. More specifically, we concentrated on word-finding failures, which increase with age. We used Diffusion tensor MRI (a technique used to image, in vivo, the diffusion of water molecules in brain tissue) to relate white matter integrity to measures of successful and unsuccessful picture naming. Diffusion tensor images were used to calculate Fractional Anisotropy (FA) images. FA is considered to be a measure of white matter organization/integrity. FA images were related to measures of successful picture naming and to word finding failures using voxel-based linear regression analyses. Successful naming rates correlated positively with white matter integrity across a broad range of regions implicated in language production. However, word finding failure rates correlated negatively with a more restricted region in the posterior aspect of superior longitudinal fasciculus. The use of DTI-MRI provides evidence for the relationship between age-related white matter changes in specific language regions and word finding failures in old age.

The Eating Disorder Examination (EDE) was originally developed and validated in primarily white female samples. Since data indicate that eating pathology impacts black youth, elucidating the psychometric appropriateness of the EDE for black youth is crucial. A convenience sample was assembled from seven pediatric obesity studies. The EDE was administered to all youth. Confirmatory factor analyses (CFA) were conducted to examine the original four-factor model fit and two alternative factor structures for black and white youth. With acceptable fit, multiple-group CFAs were conducted. For measurement invariant structures, the interactive effects of race with sex, BMIz, adiposity, and age were explored (all significance levels p < .05). For both black and white youth (N = 820; 41% black; 37% male; 6-18 years; BMIz -3.11 to 3.40), the original four-factor EDE structure and alternative eight-item one-factor structure had mixed fit via CFA. However, a seven-item, three-factor structure reflecting Dietary Restraint, Shape/Weight Overvaluation, and Body Dissatisfaction had good fit and held at the level of strict invariance. Girls reported higher factor scores than boys. BMIz and adiposity were positively associated with each subscale. Age was associated with Dietary Restraint and Body Dissatisfaction. The interactional effects between sex, BMIz, and age with race were not significant; however, the interaction between adiposity and race was significant. At higher adiposity, white youth reported greater pathology than black youth. An abbreviated seven-item, three-factor version of the EDE captures eating pathology equivalently across black and white youth. Full psychometric testing of the modified EDE factor structure in black youth is warranted. 2017 Wiley Periodicals, Inc.

Purpose of the Study: To determine if racial/ethnic disparities exist in the ownership of private long-term care insurance (LTCI) among current Medicare beneficiaries. Design and Methods: This study used the 2011 wave of the National Health and Aging Trends Study. Bivariate analysis and multivariate logistic regression were employed to isolate the independent effects of race/ethnicity on LTCI uptake. Stratified multivariate analyses were used to further examine the effect of race/ethnicity on LTCI ownership. Results: 12.3% of Blacks and 5.8% of Hispanics, compared with 20.2% of Whites (p < .001), reported having LTCI coverage. We found that Hispanics were 48% less likely to have LTCI (p = .005) compared with Whites, whereas no difference was found between Blacks and Whites. Compared with White women, Hispanic women were 81% less likely to be insured (p < .001). Ethnic disparities persisted among individuals who, based on income and assets, are considered appropriate for purchasing private LTCI coverage. Implications: This study demonstrates that ethnic differences exist in the ownership of LTCI among elderly Americans. Additional research is needed to determine what factors are responsible for the apparent underrepresentation of Hispanics in the LTCI market. PMID:24009168

EEC samples from black (n = 17) and white patients (n = 13) were analyzed by proteomics (liquid chromatography-tandem mass spectrometry) and transcriptomics (RNA-seq). Coordinate alterations were validated with RNA-seq data from black (n = 49) and white patients (n = 216). Concordantly altered candidates were further tested for associations with race-specific progression-free survival (PFS) in black (n = 64) or white patients (n = 267) via univariate and multivariate Cox regression modeling and log-rank testing. Discovery analyses revealed significantly altered candidate proteins and transcripts between black and white patients, suggesting modulation of tumor cell viability in black patients and cell death signaling in black and white patients. Eighty-nine candidates were validated as altered between these patient cohorts, and a subset significantly correlated with differential PFS. White-specific PFS candidates included serpin family A member 4 (SERPINA4; hazard ratio [HR], 0.89; Wald P value = .02), integrin subunit α3 (ITGA3; HR, 0.76; P = .03), and Bet1 Golgi vesicular membrane trafficking protein like (BET1L; HR, 0.48; P = .04). Black-specific PFS candidates included family with sequence similarity 228 member B (FAM228B; HR, 0.13; P = .001) and HEAT repeat containing 6 (HEATR6; HR, 4.94; P = .047). Several candidates were also associated with overall survival (SERPINA4 and ITGA3) as well as PFS independent of disease stage, grade and myometrial invasion (SERPINA4, BET1L and FAM228B). This study has identified and validated molecular alterations in tumors from black and white EEC patients, including candidates significantly associated with altered disease outcomes within these patient cohorts.

Data from National Health and Nutrition Examination Survey for the period 2011-2012 were used to determine normal reference ranges and percentile distributions for manganese (Mn) and selenium (Se) in blood by gender, age, race/ethnicity, socioeconomic status as determined by annual family income, and smoking status. The effect of gender, age, race/ethnicity, family income, and smoking status on the levels of Mn and Se was also determined by fitting regression models. Males had lower adjusted levels of Mn and higher adjusted levels of Se than females. Adjusted levels of Mn decreased with increase in age but adjusted levels of Se were lower in adolescents aged 12-19 years than adults aged 20-64 years. Non-Hispanic black (NHB) had the lowest levels of both Mn and Se and non-Hispanic Asians (NHAS) had the highest levels of both Mn and Se. Non-Hispanic white (NHW) and NHB had lower levels of Mn than Hispanics (HISP) and NHAS. NHB and HISP had lower levels of Se than NHW and NHAS. Low annual income (<$20,000) was associated with lower levels of Se than high annual income (≥$55,000). Smoking negatively affected the adjusted levels of Se among seniors aged ≥65 years but this was not observed in other age groups. Mn levels were not affected by smoking. Published by Elsevier GmbH.

Background: Body mass index (BMI)–for-age has been recommended as a screening test for excess adiposity in children and adolescents. Objective: We quantified the performance of standard categories of BMI-for-age relative to the population prevalence of high adiposity in children and adolescents overall and by race-ethnic group in a nationally representative US population sample by using definitions of high adiposity that are consistent with expert committee recommendations. Design: Percentage body fat in 8821 children and adolescents aged 8–19 y was measured by using dual-energy X-ray absorptiometry in 1999–2004 as part of a health examination survey. Results: With the use of several different cutoffs for percentage fat to define high adiposity, most children with high BMI-for-age (≥95th percentile of the growth charts) had high adiposity, and few children with normal BMI-for-age (<85th percentile) had high adiposity. The prevalence of high adiposity in intermediate BMI categories varied from 45% to 15% depending on the cutoff. The prevalence of a high BMI was significantly higher in non-Hispanic black girls than in non-Hispanic white girls, but the prevalence of high adiposity was not significantly different. Conclusions: Current BMI cutoffs can identify a high prevalence of high adiposity in children with high BMI-for-age and a low prevalence of high adiposity in children with normal BMI-for-age. By these adiposity measures, less than one-half of children with intermediate BMIs-for-age (85th to <95th percentile) have high adiposity. Differences in high BMI ranges between race-ethnic groups do not necessarily indicate differences in high adiposity. PMID:20164313

Race/ethnicity may be a newly recognized risk factor for Graves' disease. The aim of this study was to examine the prevalence of thyrotoxicosis by race/ethnicity in Americans aged 12-49 years using three National Health and Nutritional Examination Surveys (NHANES). Data were analyzed from 17,939 participants in NHANES III (1988-1994), NHANES 1999-2002, and NHANES 2007-2010 with available thyroid function test results. Thyrotoxicosis was defined as a serum thyrotropin (TSH) of ≤0.1 mIU/L or subjects taking methimazole or propylthiouracil, and overt thyrotoxicosis was defined as high serum thyroxine and a serum TSH of ≤0.1 mIU/L. Logistic regression was performed accounting for the complex sampling design of NHANES, and the results from all three NHANES surveys were combined using a random-effects model. There were 75 study participants with point prevalent thyrotoxicosis, representing a pooled prevalence of 0.4% for Americans aged 12-49 years. Prevalent thyrotoxicosis was nearly three times more likely in non-Hispanic black subjects compared with non-Hispanic whites (OR=2.9 [CI 1.5-5.7]), while there was no difference between the prevalence of thyrotoxicosis in Mexican Americans compared to non-Hispanic whites (OR=1.2 [CI 0.6-2.4]; I2 for heterogeneity=0% for both). Among 27 patients with overt thyrotoxicosis, the odds ratio was 8.7 [CI 0.7-112.6] for non-Hispanic blacks and 4.6 [CI 0.4-59.3] for Mexican Americans compared with non-Hispanic whites. The results suggest there are race/ethnicity differences in the prevalence of thyrotoxicosis. Future studies should address whether these differences are due to heritable factors, environmental exposures, or a combination of both.

Objective: The aim of this study is to examine social, economic, and health factors related to paid work in well-functioning older adults and if and how these factors vary by race. Method: We used sex-stratified logistic and multinomial logistic regression to examine cross-sectional data in the Health, Aging, and Body Composition cohort study. The sample included 3,075 community-dwelling Black (42%) and White adults aged 70 to 79 at baseline. Results: Multinomial logistic regression analyses show Black men were more likely to work full-time, and Black women were more likely to work part-time. Men with ≥US$50,000 family income were more likely to work full-time. Men with better physical functioning were more likely to work full- and part-time. Women with ≥US$50,000 family income and fewer chronic diseases were more likely to work full-time. Women who were overweight and had fewer chronic diseases were more likely to work part-time. Discussion: Results suggest that well-functioning, older Black adults were more likely to work than their White counterparts, and working relates to better health and higher income, providing support for a productive or successful aging perspective.

The U.S. Centers for Disease Control and Prevention has reported that nutritional deficiencies in the U.S. population vary by age, gender, and race/ethnicity, and could be as high as nearly one third of certain population groups. Based on nationally representative data in 10,698 adults from National Health and Nutrition Examination Surveys (NHANES) primarily from 2009-2012, assessments were made of race/ethnic differences in the impact of dietary supplements on nutrient intake and prevalence of inadequacies. Compared to food alone, use of any dietary supplement plus food was associated with significantly higher intakes of 14 to 16 of 19 nutrients examined in all race/ethnic groups; and significantly ( p < 0.01) reduced rates of inadequacy for 8/17 nutrients examined in non-Hispanic whites, but only 3-4/17 nutrients (calcium, and vitamins A, D, and E) for other race/ethnic groups. Across race/ethnic groups an increased prevalence of intakes above the Tolerable Upper Intake Level (UL) was seen for 1-9/13 nutrients, but all were less than 5% of the population. In conclusion, use of dietary supplements is associated with increased micronutrient intake, decreased nutrient inadequacies, and slight increases in prevalence above the UL in all race/ethnicities examined, with greater benefits among non-Hispanic whites.

Although research on discrimination and health has progressed significantly, it has tended to focus on racial discrimination and US populations. This study explored different types of discrimination, their interactions and associations with common mental disorders among Brazilian university students, in Rio de Janeiro in 2010. Associations between discrimination and common mental disorders were examined using multiple logistic regression models, adjusted for confounders. Interactions between discrimination and socio-demographics were tested. Discrimination attributed to age, class and skin color/race were the most frequently reported. In a fully adjusted model, discrimination attributed to skin color/race and class were both independently associated with increased odds of common mental disorders. The simultaneous reporting of skin color/race, class and age discrimination was associated with the highest odds ratio. No significant interactions were found. Skin color/race and class discrimination were important, but their simultaneous reporting, in conjunction with age discrimination, were associated with the highest occurrence of common mental disorders.

Stevens, J A; Dellinger, A M

2002-12-01

To examine differences in motor vehicle and fall related death rates among older adults by sex, race, and ethnicity. Annual mortality tapes for 1990-98 provided demographic data including race and ethnicity, date, and cause of death. Trend analyses were conducted using Poisson regression. From 1990-98, overall motor vehicle related death rates remained stable while death rates from unintentional falls increased. Motor vehicle and fall related death rates were higher among men. Motor vehicle related death rates were higher among people of color while fall related death rates were higher among whites. Among whites, fall death rates increased significantly during the study period, with an annual relative increase of 3.6% for men and 3.2% for women. The risk of death from motor vehicle and fall related injuries among older adults differed by sex, race and ethnicity, results obscured by simple age and sex specific death rates. This study found important patterns and disparities in these death rates by race and ethnicity useful for identifying high risk groups and guiding prevention strategies.

We analyze if race can be considered a limiting factor in the use of dental services by the elderly. This study is of an analytical nature, with the use of secondary data collected by the National Survey of Oral Health in 2003. Those examined who declared themselves as being white, brown or black in the 65 to 74-year-old age bracket were included. The sample was composed of 5,108 elderly people: 2,575 whites and 2,533 blacks. Of the whites, 3.8% stated that they had never been to the dentist, while this figure was 7.8% for the blacks. Even after the adjustment for interception for prosthetics and dental pain, the chance of elderly blacks not having used dental services at least once in their life is 0.62 OR less than for elderly whites. Of those who used the services, 21.2% of the elderly whites visited the dentist in the last year, while for elderly blacks the figure was 14.2%, in the adjusted model for interception for prosthetics and dental pain the OR was 0.60. All the relations were statistically significant (p<0,001). Race is a limiting factor in the use of dental services by the elderly and even after the adjustments the elderly blacks continue to manifest greater resistance to the use of oral health services.

The development of the own-race advantage in school-age children: A morphing face paradigm

Tai, Chu-Lik; Yang, Shu-Fei

Previous studies examining the other-race effect in school-age children mostly focused on recognition memory performance. Here we investigated perceptual discriminability for Asian-like versus Caucasian-like morph faces in school-age Taiwanese children and adults. One-hundred-and-two 5- to 12-year-old children and twenty-three adults performed a sequential same/different face matching task, where they viewed an Asian- or a Caucasian-parent face followed by either the same parent face or a different morphed face (containing 15%, 30%, 45%, or 60% contribution from the other parent face) and judged if the two faces looked the same. We computed the d’ as the sensitivity index for each age groups. We also analyzed the group mean rejection rates as a function of the morph level and fitted with a cumulative normal distribution function. Results showed that the adults and the oldest 11-12-year-old children exhibited a greater sensitivity (d’) and a smaller discrimination threshold (μ) in the Asian-parent condition than those in the Caucasian-parent condition, indicating the presence of an own-race advantage. On the contrary, 5- to 10-year-old children showed an equal sensitivity and similar discrimination thresholds for both conditions, indicating an absence of the own-race advantage. Moreover, a gradual development in enhancing the discriminability for the Asian-parent condition was observed from age 5 to 12; however, the progression in the Caucasian-parent condition was less apparent. In sum, our findings suggest that expertise in face processing may take the entire childhood to develop, and supports the perceptual learning view of the other-race effect—the own-race advantage seen in adulthood likely reflects a result of prolonged learning specific to faces most commonly seen in one’s visual environment such as own-race faces.

Objective Previous studies have speculated that the higher stroke incidence rate in blacks compared with whites may be due, in part, to stroke risk factors exerting a more adverse effect among blacks than whites. To determine whether such racial differences exist we compared the prospective associations between novel, traditional and emerging stroke risk factors in blacks and whites. Design Baseline characteristics on risk factor levels were obtained on 15,407 participants from the Atherosclerosis Risk in Communities Study. Stroke incidence was ascertained from 1987–2008. Adjusted Cox proportional hazard models were used to compute hazard ratios (HRs) and their 95% confidence intervals (CIs) for stroke in relation to stroke risk factor levels stratified by race. Results During follow-up 988 stroke events occurred: Blacks had higher stroke incident rates compared with whites with the greatest difference in those aged <60 years: 4.34, 3.24, 1.20 and 0.84 per 1,000 person-years, in black men, black women, white men and white women, respectively. Associations between risk factors with incident stroke were similar in blacks and whites excluding diabetes which was more strongly associated with risk of stroke in blacks than in whites: HR 2.54 (95% CI: 2.03–3.18) vs. 1.74 (1.37–2.21), respectively; p for race interaction=0.02. Conclusions At all ages, blacks are at considerably higher risk of incident stroke compared with whites, although the effect is most marked in younger age groups. This is most likely due to blacks having a greater burden of stroke risk factors rather than there being any substantial race differences in the associations between risk factors and stroke outcomes.

Financial literacy, the ability to understand, access, and utilize information in ways that contribute to optimal financial outcomes, is important for independence and wellbeing in old age. We previously reported that financial literacy is associated with greater functional connectivity between brain regions in old age. Here, we tested the hypothesis that higher financial literacy would be associated with greater white matter integrity in old age. Participants included 346 persons without dementia (mean age=81.36, mean education=15.39, male/female=79/267, mean MMSE=28.52) from the Rush Memory and Aging Project. Financial literacy was assessed using a series of questions imbedded as part of an ongoing decision making study. White matter integrity was assessed with diffusion anisotropy measured with diffusion tensor magnetic resonance imaging (DTI). We tested the hypothesis that higher financial literacy is associated with higher diffusion anisotropy in white matter, adjusting for the effects of age, education, sex, and white matter hyperintense lesions. We then repeated the analysis also adjusting for cognitive function. Analyses revealed regions with significant positive associations between financial literacy and diffusion anisotropy, and many remained significant after accounting for cognitive function. White matter tracts connecting right hemisphere temporal-parietal brain regions were particularly implicated. Greater financial literacy is associated with higher diffusion anisotropy in white matter of nondemented older adults after adjusting for important covariates. These results suggest that financial literacy is positively associated with white matter integrity in old age. PMID:26899784

Attitudes about race predict individual differences in face adaptation aftereffects.

Elliott, Sarah L; Chu, Kelly; Coleman, Jill

2017-12-01

This study examined whether category boundaries between Black and White faces relate to individual attitudes about race. Fifty-seven (20 Black, 37 White) participants completed measures of explicit racism, implicit racism, collective self-esteem (CSE), and racial centrality. Category boundaries between Black and White faces were measured in three separate conditions: following adaptation to (1) a neutral gray background, a sequence of (2) Black or (3) White faces. Two additional conditions measured category boundaries for facial distortion to investigate whether attitudes relate to mechanisms of racial identity alone, or to more global mechanisms of face perception. Using a two-alternative forced-choice staircase procedure, participants indicated whether a test image appeared to be Black or White (or contracted or expanded). Following neutral adaptation, participants with higher CSE showed category boundaries shifted toward faces with a higher percentage of Black features. In addition, the strength of short-term sensitivity shifts following adaptation to Black and White faces was related to explicit and implicit attitudes about race. Sensitivity shifts were weaker when participants scored higher on explicit racism, but were stronger when participants scored higher on implicit but lower on explicit racism. The results of this study indicate that attitudes about race account for some individual differences in natural category boundaries between races as well as the strength of identity aftereffects following face adaptation.

Measuring sexual dimorphism with a race-gender face space.

PubMed

Hopper, William J; Finklea, Kristin M; Winkielman, Piotr; Huber, David E

2014-10-01

Faces are complex visual objects, and faces chosen to vary in 1 regard may unintentionally vary in other ways, particularly if the correlation is a property of the population of faces. Here, we present an example of a correlation that arises from differences in the degree of sexual dimorphism. In Experiment 1, paired similarity ratings were collected for a set of 40 real face images chosen to vary in terms of gender and race (Asian vs. White). Multidimensional scaling (MDS) placed these stimuli in a "face space," with different attributes corresponding to different dimensions. Gender was found to vary more for White faces, resulting in a negative or positive correlation between gender and race when only considering male or only considering female faces. This increased sexual dimorphism for White faces may provide an alternative explanation for differences in face processing between White and Asian faces (e.g., the own-race bias, face attractiveness biases, etc.). Studies of face processing that are unconfounded by this difference in the degree of sexual dimorphism require stimuli that are decorrelated in terms of race and gender. Decorrelated faces were created using a morphing technique, spacing the morphs uniformly around a ring in the 2-dimensional (2D) race-gender plane. In Experiment 2, paired similarity ratings confirmed the 2D positions of the morph faces. In Experiment 3, race and gender category judgments varied uniformly for these decorrelated stimuli. Our results and stimuli should prove useful for studying sexual dimorphism and for the study of face processing more generally.

Aims This study assesses how race/ethnicity and socioeconomic status (SES) modify the relationship between exposure to movie smoking and having tried smoking in adolescents. Design Data come from a cross-sectional telephone survey and were analyzed using logistic regression models. A respondent reporting ever having tried smoking was regressed on exposure to movie smoking, race, socioeconomic status, the interactions of these variables, and family and background characteristics. Setting National sample of US adolescents. Participants 3653 respondents aged 13–18 years. Measurements Outcome was if subjects reported ever having tried smoking. Movie smoking exposure was assessed through respondents’ reporting having watched a set of movie titles, which were coded for smoking instances. Findings The proportion having tried smoking was lower for Blacks (0.32) compared to Hispanics (0.41) and Whites (0.38). The relationship between movie smoking and having tried smoking varied by race/ethnicity. Among Whites and Hispanics exposure to movie smoking positively predicted smoking behavior, but movie smoking had no impact on Blacks. SES further modified the relation among Whites; high SES white adolescents were more susceptible to movie smoking than low SES white adolescents. Conclusions Exposure to movie smoking is not uniformly experienced as a risk factor for having ever tried smoking among U.S. adolescents. Whites and Hispanics are more likely to try smoking as a function of increased exposure to movie smoking. In addition, higher socioeconomic status increases susceptibility to movie smoking among Whites. Youth with fewer risk factors may be more influenced by media messages on smoking. PMID:22724674

Purpose. This study examined the association between peripapillary choroidal thickness (PCT) with age and race in a group of African descent (AD) and European descent (ED) subjects with normal eyes. Methods. Optic nerve head images from enhanced depth imaging spectral-domain optical coherence tomography of 166 normal eyes from 84 subjects of AD and ED were manually delineated to identify the principal surfaces of Bruch's membrane (BM), Bruch's membrane opening (BMO), and anterior sclera (AS). Peripapillary choroidal thickness was measured between BM and AS at increasing distance away from BMO. The mean PCT was compared between AD and ED subjects and generalized estimating equation (GEE) regression analysis was used to examine the association between race and PCT overall, in each quadrant, and by distance from BMO. Models were adjusted for age, BMO area, and axial length in the regression analysis. Results. Overall, the mean PCT increased from 63.9 μm ± 18.1 at 0 to 250 μm to 170.3 μm ± 56.7 at 1500 to 2000 μm from BMO. Individuals of AD had a greater mean PCT than those of ED at all distances from BMO (P < 0.05 at each distance) and in each quadrant (P < 0.05 in each quadrant). Results from multivariate regression indicate that ED subjects had significantly lower PCT compared to AD overall and in all quadrants and distances from BMO. Increasing age was also significantly associated with a lower PCT in both ED and AD participants. Conclusions. Peripapillary choroidal thickness varies with race and age, as individuals of AD have a thicker peripapillary choroid than those of ED. (ClinicalTrials.gov number, NCT00221923.) PMID:25711640

Postencoding cognitive processes in the cross-race effect: Categorization and individuation during face recognition.

PubMed

Ho, Michael R; Pezdek, Kathy

2016-06-01

The cross-race effect (CRE) describes the finding that same-race faces are recognized more accurately than cross-race faces. According to social-cognitive theories of the CRE, processes of categorization and individuation at encoding account for differential recognition of same- and cross-race faces. Recent face memory research has suggested that similar but distinct categorization and individuation processes also occur postencoding, at recognition. Using a divided-attention paradigm, in Experiments 1A and 1B we tested and confirmed the hypothesis that distinct postencoding categorization and individuation processes occur during the recognition of same- and cross-race faces. Specifically, postencoding configural divided-attention tasks impaired recognition accuracy more for same-race than for cross-race faces; on the other hand, for White (but not Black) participants, postencoding featural divided-attention tasks impaired recognition accuracy more for cross-race than for same-race faces. A social categorization paradigm used in Experiments 2A and 2B tested the hypothesis that the postencoding in-group or out-group social orientation to faces affects categorization and individuation processes during the recognition of same-race and cross-race faces. Postencoding out-group orientation to faces resulted in categorization for White but not for Black participants. This was evidenced by White participants' impaired recognition accuracy for same-race but not for cross-race out-group faces. Postencoding in-group orientation to faces had no effect on recognition accuracy for either same-race or cross-race faces. The results of Experiments 2A and 2B suggest that this social orientation facilitates White but not Black participants' individuation and categorization processes at recognition. Models of recognition memory for same-race and cross-race faces need to account for processing differences that occur at both encoding and recognition.

Background Clinical manifestations and outcomes of atherosclerotic disease differ between ethnic groups. In addition, the prevalence of risk factors is substantially different. Primary prevention programs are based on data derived from almost exclusively White people. We investigated how race/ethnic differences modify the associations of established risk factors with atherosclerosis and cardiovascular events. Methods We used data from an ongoing individual participant meta-analysis involving 17 population-based cohorts worldwide. We selected 60,211 participants without cardiovascular disease at baseline with available data on ethnicity (White, Black, Asian or Hispanic). We generated a multivariable linear regression model containing risk factors and ethnicity predicting mean common carotid intima-media thickness (CIMT) and a multivariable Cox regression model predicting myocardial infarction or stroke. For each risk factor we assessed how the association with the preclinical and clinical measures of cardiovascular atherosclerotic disease was affected by ethnicity. Results Ethnicity appeared to significantly modify the associations between risk factors and CIMT and cardiovascular events. The association between age and CIMT was weaker in Blacks and Hispanics. Systolic blood pressure associated more strongly with CIMT in Asians. HDL cholesterol and smoking associated less with CIMT in Blacks. Furthermore, the association of age and total cholesterol levels with the occurrence of cardiovascular events differed between Blacks and Whites. Conclusion The magnitude of associations between risk factors and the presence of atherosclerotic disease differs between race/ethnic groups. These subtle, yet significant differences provide insight in the etiology of cardiovascular disease among race/ethnic groups. These insights aid the race/ethnic-specific implementation of primary prevention. PMID:26134404

Clinical manifestations and outcomes of atherosclerotic disease differ between ethnic groups. In addition, the prevalence of risk factors is substantially different. Primary prevention programs are based on data derived from almost exclusively White people. We investigated how race/ethnic differences modify the associations of established risk factors with atherosclerosis and cardiovascular events.

Objective Consumer assessments of health care provide important information about how well health plans and clinicians meet the needs of the people they serve. The purpose of this study was to examine whether consumer reports and ratings of care in Medicaid managed care vary by race/ethnicity and language. Data Sources Data were derived from the National CAHPS ® Benchmarking Database (NCBD) 3.0 and consisted of 49,327 adults enrolled in Medicaid managed care plans in 14 states in 2000. Data Collection The CAHPS® data were collected by telephone and mail. Surveys were administered in Spanish and English. The response rate across plans was 38 percent. Study Design Data were analyzed using linear regression models. The dependent variables were CAHPS ® 2.0 global rating items (personal doctor, specialist, health care, health plan) and multi-item reports of care (getting needed care, timeliness of care, provider communication, staff helpfulness, plan service). The independent variables were race/ethnicity, language spoken at home (English, Spanish, Other), and survey language (English or Spanish). Survey respondents were assigned to one of nine racial/ethnic categories based on Hispanic ethnicity and race: White, Hispanic/Latino, Black/African American, Asian/Pacific Islanders, American Indian/Alaskan native, American Indian/White, Black/White, Other Multiracial, Other Race/Ethnicity. Whites, Asians, and Hispanics were further classified into language subgroups based on the survey language and based on the language primarily spoken at home. Covariates included gender, age, education, and self-rated health. Principal Findings Racial/ethnic and linguistic minorities tended to report worse care than did whites. Linguistic minorities reported worse care than did racial and ethnic minorities. Conclusions This study suggests that racial and ethnic minorities and persons with limited English proficiency face barriers to care, despite Medicaid-enabled financial access

Race is an independent factor in health disparity. We developed a training module to address race, racism, and health care. A group of 19 physicians participated in our training module. Anonymous survey results before and after the training were compared using a two-sample t-test. The awareness of racism and its impact on care increased in all participants. White participants showed a decrease in self-efficacy in caring for patients of color when compared to white patients. This training was successful in deconstructing white providers' previously held beliefs about race and racism. © 2015 Wiley Periodicals, Inc.

Race-based disparities in operative morbidity and mortality have been demonstrated for various procedures, including pancreatoduodenectomy (PD). Race-based differences in hospital length-of-stay (LOS), especially related to provider volume at the surgeon and hospital level, remain poorly defined. Using the 2003-2009 Nationwide Inpatient Sample, we determined year-specific PD volumes for surgeons and hospitals and grouped them into terciles. Patient race (white, black, or Hispanic), age, sex, and comorbidities were examined. Median length of stay was calculated, and multivariable logistic regression was used to examine factors associated with increased LOS. Among 4,319 eligible individuals, 3,502 (81.1%) were white, 423 (9.8%) were black, and 394 (9.1%) were Hispanic. Overall median LOS was 12 days (range, 0-234). Median annual surgeon volume was 8 (interquartile range [IQR], 2-19; range, 1-54). Annual hospital volume ranged from 1 to 129 (median, 19; IQR, 7-55). White patients were more likely to have been treated at medium- to high-volume hospitals (odds ratio [OR] 1.53, P < .001) and by medium- to high-volume surgeons (OR 1.62, P < .001) than black or Hispanic patients. After PD, white, black, and Hispanic patients demonstrated similar in-hospital mortality (5.1%, 5.7% and 7.2% respectively P = .250). After adjustment, black (OR 1.36, P = .010) and Hispanic (OR 1.68, P < .001) patients were more likely to have a greater LOS after PD. Black and Hispanic PD patients were less likely than white patients to be treated at higher-volume hospitals and by higher-volume surgeons. Proportional mortality and LOS after PD were greater among black and Hispanic patients. Copyright © 2014 Mosby, Inc. All rights reserved.

Background. We examined the association between insufficient rest/sleep and cardiovascular disease or diabetes mellitus separately among non-Hispanic whites, non-Hispanic blacks, Hispanic Americans, and other races in a contemporary sample of US adults. Methods. Multiethnic, nationally representative, cross-sectional survey (2008 BRFSS) participants who were >20 years of age (n = 369, 217; 50% women). Self-reported insufficient rest/sleep in the previous month was categorized into: zero, 1-13, 14-29, and all 30 days. Outcomes were: (1) any CVD, (2) coronary artery disease (CHD), (3) stroke, and (4) diabetes mellitus. Results. Insufficient rest/sleep was found to be positively associated with (1) any CVD, (2) CHD, and (3) stroke among all race-ethnicities. In contrast, insufficient rest/sleep was positively associated with diabetes mellitus in all race-ethnicities except non-Hispanic blacks. The odds ratio of diabetes association with insufficient rest/sleep for all 30 days was 1.37 (1.26-1.48) among non-Hispanic whites, 1.11 (0.90-1.36) among non-Hispanic blacks, 1.88 (1.46-2.42) among Hispanic Americans, and 1.48 (1.10-2.00) among other race/ethnicities. Conclusion. In a multiethnic sample of US adults, perceived insufficient rest/sleep was associated with CVD, among all race-ethnicities. However, the association between insufficient rest/sleep and diabetes mellitus was present among all race-ethnicities except non-Hispanic blacks.

1999-01-01

The anatomy of the psoas major muscle (PMA) in young black and white men was studied during routine autopsies. The forensic autopsies included 44 fresh male cadavers (21 black, 23 white) with an age span of 14 to 25 y. The range for weight was 66–76 kg and for height 169–182 cm. The PMA was initially measured in its entire length before measuring the diameter and circumference at each segmental level (L1–S1). At each segmental level, the calculated anatomical cross-sectional area (ACSA) was more than 3 times greater in the black group compared with the white (P<0.001). The psoas minor muscle (PMI) was absent in 91% of the black subjects, but only in 13% of the white subjects. These data show that the PMA is markedly larger in black than white subjects. The marked race specific difference in the size of the PMA may have implications for hip flexor strength, spine function and race specific incidence in low back pathology, and warrants further investigation.

2012-03-01

To date, there is no consensus regarding adult cutoffs of percentage of body fat or estimated cutoffs on the basis of nationally representative samples with rigorous body-composition measurements. We developed cutoffs of percentage of body fat on the basis of the relation between dual-energy x-ray absorptiometry-measured fat mass and BMI (in kg/m(2)) stratified by sex, age, and race-ethnicity by using 1999-2004 NHANES data. A simple regression (percentage of body fat = β(0) + β(1) × 1 ÷ BMI) was fit for each combination of sex (men and women), 3 age groups (18-29, 30-49, and 50-84 y of age), and 3 race-ethnicity groups (non-Hispanic whites, non-Hispanic blacks, and Mexican Americans). Model fitting included a consideration of complex survey design and multiple imputations. Cutoffs of percentage of body fat were computed that corresponded to BMI cutoffs of 18.5, 25, 30, 35, and 40 on the basis of estimated prediction equations. R(2) ranged from 0.54 to 0.72 for men (n = 6544) and 0.58 to 0.79 for women (n = 6362). In men, the percentage of body fat that corresponded to a BMI of 18.5, 25, 30, 35, and 40 across age and racial-ethnic groups ranged from 12.2% to 19.0%, 22.6% to 28.0%, 27.5% to 32.3%, 31.0% to 35.3%, and 33.6% to 37.6%, respectively; the corresponding ranges in women were from 24.6% to 32.3%, 35.0% to 40.2%, 39.9% to 44.1%, 43.4% to 47.1%, and 46.1% to 49.4%, respectively. The oldest age group had the highest cutoffs of percentage of body fat. Non-Hispanic blacks had the lowest cutoffs of percentage of body fat. Cutoffs of percentage of body fat were higher in women than in men. Cutoffs of percentage of body fat that correspond to the current US BMI cutoffs are a function of sex, age, and race-ethnicity. These factors should be taken into account when considering the appropriateness of levels of percentage of body fat.

Increased life expectancy, growth of minority populations, and advances in cancer screening and treatment have resulted in an increasing number of older, racially diverse cancer survivors. Potential black/white disparities in cancer incidence, stage, and survival among the oldest old (≥85 years) were examined using data from the SEER Program of the National Cancer Institute. Differences in cancer incidence and stage at diagnosis were examined for cases diagnosed within the most recent 5-year period, and changes in these differences over time were examined for white and black cases aged ≥85 years. Five-year relative cancer survival rate was also examined by race. Among those aged ≥85 years, black men had higher colorectal, lung and bronchus, and prostate cancer incidence rates than white men, respectively. From 1973 to 2012, lung and bronchus and female breast cancer incidence increased, while colorectal and prostate cancer incidence decreased among this population. Blacks had higher rates of unstaged cancer compared with whites. The 5-year relative survival rate for all invasive cancers combined was higher for whites than blacks. Notably, whites had more than three times the relative survival rate of lung and bronchus cancer when diagnosed at localized (35.1% vs. 11.6%) and regional (12.2% vs. 3.2%) stages than blacks, respectively. White and black differences in cancer incidence, stage, and survival exist in the ≥85 population. Continued efforts are needed to reduce white and black differences in cancer prevention and treatment among the ≥85 population.

The authors examined gender and racial preferential behaviour in 108 3- and 5-year-old Black and White girls. Children set up a birthday party for dolls that differed in gender and racial physical characteristics. Whereas White girls showed favouritism towards the doll most closely resembling themselves in both gender and race, Black girls showed most favouritism towards the White girl doll. Black girls were more likely to show preference based on gender rather than race, whereas White girls were equally likely to show race- or gender-based favouritism. Among White 5-year-olds, greater prior interaction with Blacks was positively associated with race-related favouritism (i.e., secondary preference to the White boy doll rather than the Black girl doll). Interracial contact was unrelated to racial favouritism among the other three groups. Results demonstrate the salience of gender identity during the preschool years, and indicate that majority/minority status and intergroup contact shape the development of collective identity and social behaviour.

Financial literacy, the ability to understand, access, and utilize information in ways that contribute to optimal financial outcomes, is important for independence and wellbeing in old age. We previously reported that financial literacy is associated with greater functional connectivity between brain regions in old age. Here, we tested the hypothesis that higher financial literacy would be associated with greater white matter integrity in old age. Participants included 346 persons without dementia (mean age=81.36, mean education=15.39, male/female=79/267, mean MMSE=28.52) from the Rush Memory and Aging Project. Financial literacy was assessed using a series of questions imbedded as part of an ongoing decision making study. White matter integrity was assessed with diffusion anisotropy measured with diffusion tensor magnetic resonance imaging (DTI). We tested the hypothesis that higher financial literacy is associated with higher diffusion anisotropy in white matter, adjusting for the effects of age, education, sex, and white matter hyperintense lesions. We then repeated the analysis also adjusting for cognitive function. Analyses revealed regions with significant positive associations between financial literacy and diffusion anisotropy, and many remained significant after accounting for cognitive function. White matter tracts connecting right hemisphere temporal-parietal brain regions were particularly implicated. Greater financial literacy is associated with higher diffusion anisotropy in white matter of nondemented older adults after adjusting for important covariates. These results suggest that financial literacy is positively associated with white matter integrity in old age. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

The social patterns of a biological risk factor for disease: race, gender, socioeconomic position, and C-reactive protein.

Understand the links between race and C-reactive protein (CRP), with special attention to gender differences and the role of class and behavioral risk factors as mediators. This study utilizes the National Social Life, Health, and Aging Project data, a nationally representative study of older Americans aged 57-85 to explore two research questions. First, what is the relative strength of socioeconomic versus behavioral risk factors in explaining race differences in CRP levels? Second, what role does gender play in understanding race differences? Does the relative role of socioeconomic and behavioral risk factors in explaining race differences vary when examining men and women separately? When examining men and women separately, socioeconomic and behavioral risk factor mediators vary in their importance. Indeed, racial differences in CRP among men aged 57-74 are little changed after adjusting for both socioeconomic and behavioral risk factors with levels 35% higher for black men as compared to white men. For women aged 57-74, however, behavioral risk factors explain 30% of the relationship between race and CRP. The limited explanatory power of socioeconomic position and, particularly, behavioral risk factors, in elucidating the relationship between race and CRP among men, signals the need for research to examine additional mediators, including more direct measures of stress and discrimination.

The Effects of Race, Ethnicity, and Mood/Anxiety Disorders on the Chronic Physical Health Conditions of Men From a National Sample

2013-01-01

Racial/ethnic differences in health are evident among men. Previous work suggests associations between mental and physical health but few studies have examined how mood/anxiety disorders and chronic physical health conditions covary by age, race, and ethnicity among men. Using data from 1,277 African American, 629 Caribbean Black, and 371 non-Hispanic White men from the National Survey of American Life, we examined associations between race/ethnicity and experiencing one or more chronic physical health conditions in logistic regression models stratified by age and 12-month mood/anxiety disorder status. Among men <45 years without mood/anxiety disorders, Caribbean Blacks had lower odds of chronic physical health conditions than Whites. Among men aged 45+ years with mood/anxiety disorders, African Americans had greater odds of chronic physical health conditions than Whites. Future studies should explore the underlying causes of such variation and how studying mental and chronic physical health problems together may help identify mechanisms that underlie racial disparities in life expectancy among men.

2012-12-01

Few studies have examined clinical trial participation rates and treatment outcomes among underserved young adults who are dependent on marijuana, the most commonly abused illicit drug. The present study was a secondary analysis of a trial of court-referred marijuana-dependent young adults (ages 18-25) randomized to one of four treatment conditions: Motivational Enhancement Therapy/Cognitive Behavioral Therapy (MET/CBT), MET/CBT+Contingency Management (CM), Drug Counseling (DC) or DC+CM. African American (N=81) participants were compared to White (N=31) participants with respect to rates of participation in phases of treatment and substance use outcomes. In addition, the interaction of race and treatment condition was examined to ascertain if the interventions yielded different effects based on race. Among those who started treatment, African American young adults were significantly less likely to complete the treatment and posttreatment phases of the clinical trial than their White counterparts. Irrespective of treatment type, substance use outcomes (i.e., percentage of marijuana-negative specimens and longest duration of continuous abstinence) did not vary by race. However, there was a significant interaction effect between treatment type and race; African American young adults did not benefit differentially from any specific type of treatment, but CM was effective in reducing proportion of marijuana positive samples among White young adults. Findings suggest that clinical trial treatment and posttreatment completion rates vary by race in this population, as does response to specific treatment types. More treatment research focusing specifically on African American marijuana-dependent young adults is warranted. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Age, training, and previous experience predict race performance in long-distance inline skaters, not anthropometry.

2012-02-01

The association of characteristics of anthropometry, training, and previous experience with race time in 84 recreational, long-distance, inline skaters at the longest inline marathon in Europe (111 km), the Inline One-eleven in Switzerland, was investigated to identify predictor variables for performance. Age, duration per training unit, and personal best time were the only three variables related to race time in a multiple regression, while none of the 16 anthropometric variables were related. Anthropometric characteristics seem to be of no importance for a fast race time in a long-distance inline skating race in contrast to training volume and previous experience, when controlled with covariates. Improving performance in a long-distance inline skating race might be related to a high training volume and previous race experience. Also, doing such a race requires a parallel psychological effort, mental stamina, focus, and persistence. This may be reflected in the preparation and training for the event. Future studies should investigate what motivates these athletes to train and compete.

Evidence suggests that race affects the prevalence and incidence of urinary incontinence (UI) in women. But little is known about racial differences in the rates of remission, improvement, and progression of UI in women. We sought to compare changes in UI frequency over two years among Asian, black, and white women with UI. Participants in the Nurses' Health Study and the Nurses' Health Study II responded to mailed questionnaires (in 2000 and 2002, and 2001 and 2003, respectively), giving information on race and the frequency of UI. Prospective analyses were conducted over two years from data gathered on 57,900 women, ages 37 to 79, who had at least monthly UI at baseline. Over the two two-year study periods, black women were significantly more likely than white women to report remission of UI (14% versus 9%, respectively), and Asian women were significantly more likely than white women to report less frequent UI (40% versus 31%, respectively). Improvement was more common in older black women than in older white women, but rates of improvement were comparable between younger black and younger white women. Black women were less likely than white women to report more frequent UI at follow-up (30% versus 34%, respectively), and, after adjusting for health and lifestyle factors, the difference was borderline statistically significant. Changes in the frequency of UI appear to vary by race, even after adjustment for risk factors. These findings may account for some of the previously observed differences in UI prevalence across racial groups. Although UI is a common condition in women of all races, nurses and other clinicians should be aware that its presentation may vary according to race. Such an understanding could increase clinicians' confidence in discussing UI with patients, reducing the possibility that the condition goes unrecognized. epidemiology, progression, race, remission, urinary incontinence.

Chronic neuroinflammation, which is primarily mediated by microglia, plays an essential role in aging and neurodegeneration. It is still unclear whether this microglia-induced neuroinflammation occurs globally or is confined to distinct brain regions. In this study, we investigated microglia activity in various brain regions upon healthy aging and Alzheimer’s disease (AD)-related pathology in both human and mouse samples. In purified microglia isolated from aging mouse brains, we found a profound gene expression pattern related to pro-inflammatory processes, phagocytosis, and lipid homeostasis. Particularly in white matter microglia of 24-month-old mice, abundant expression of phagocytic markers including Mac-2, Axl, CD16/32, Dectin1, CD11c, and CD36 was detected. Interestingly, in white matter of human brain tissue the first signs of inflammatory activity were already detected during middle age. Thus quantification of microglial proteins, such as CD68 (commonly associated with phagocytosis) and HLA-DR (associated with antigen presentation), in postmortem human white matter brain tissue showed an age-dependent increase in immunoreactivity already in middle-aged people (53.2 ± 2.0 years). This early inflammation was also detectable by non-invasive positron emission tomography imaging using [11C]-(R)-PK11195, a ligand that binds to activated microglia. Increased microglia activity was also prominently present in the white matter of human postmortem early-onset AD (EOAD) brain tissue. Interestingly, microglia activity in the white matter of late-onset AD (LOAD) CNS was similar to that of the aged clinically silent AD cases. These data indicate that microglia-induced neuroinflammation is predominant in the white matter of aging mice and humans as well as in EOAD brains. This white matter inflammation may contribute to the progression of neurodegeneration, and have prognostic value for detecting the onset and progression of aging and neurodegeneration. PMID:28713239

Race/ethnic differences in desired body mass index and dieting practices among young women attending college in Hawai'i.

2011-07-01

In accordance with the sociocultural model, race/ethnicity is considered a major influence on factors associated with body image and body dissatisfaction, and eating disorders are often characterized as problems that are primarily limited to young White women from Western cultures. The purpose of this study was to determine whether there are differences that exist by race in desired body weight; the importance placed on those ideals; and dieting strategies among White, Asian American, Native Hawaiian/Pacific Islanders, and other mixed-race young women in Hawai'i. A total of 144 female college students 18-20 years of age were surveyed about body weight as well as eating and exercise habits. Results demonstrated that all the young women wanted to lose weight. However, there were no differences in desired body weight or desired weight change by race after controlling for body mass index suggesting that current weight rather than race/ethnicity is the predominant influence on weight-related concerns. Young White women placed the greatest level of importance on achieving a lower body weight, which corresponded with a greater likelihood to be attempting weight loss (dieting) and greater endorsement of behaviors consistent with weight loss compared to their counterparts. Findings imply that, for young women, race/ethnicity may not have as significant an impact on factors associated with body weight ideals as previously believed. Rather, differences in the value placed on achieving a desired body weight, as it relates to disordered eating, should be further explored among race/ethnic groups.

This study examined race differences in the probability of belonging to a specific social network typology of family, friends, and church members. Samples of African Americans, Caribbean blacks, and non-Hispanic whites aged 55+ were drawn from the National Survey of American Life. Typology indicators related to social integration and negative interactions with family, friendship, and church networks were used. Latent class analysis was used to identify typologies, and latent class multinomial logistic regression was used to assess the influence of race, and interactions between race and age, and race and education on typology membership. Four network typologies were identified: optimal (high social integration, low negative interaction), family-centered (high social integration within primarily the extended family network, low negative interaction), strained (low social integration, high negative interaction), and ambivalent (high social integration and high negative interaction). Findings for race and age and race and education interactions indicated that the effects of education and age on typology membership varied by race. Overall, the findings demonstrate how race interacts with age and education to influence the probability of belonging to particular network types. A better understanding of the influence of race, education, and age on social network typologies will inform future research and theoretical developments in this area. © The Author 2017.

Background We sought 0074o build models that address questions of interest to patients and families by predicting short- and long-term mortality and functional outcome after ischemic stroke, while allowing for risk re-stratification as comorbid events accumulate. Methods A cohort of 451 ischemic stroke subjects in 1999 were interviewed during hospitalization, at 3 months, and at approximately 4 years. Medical records from the acute hospitalization were abstracted. All hospitalizations for 3 months post-stroke were reviewed to ascertain medical and psychiatric comorbidities, which were categorized for analysis. Multivariable models were derived to predict mortality and functional outcome (modified Rankin Scale) at 3 months and 4 years. Comorbidities were included as modifiers of the 3 month models, and included in 4-year predictions. Results Post-stroke medical and psychiatric comorbidities significantly increased short term post-stroke mortality and morbidity. Severe periventricular white matter disease (PVWMD) was significantly associated with poor functional outcome at 3 months, independent of other factors, such as diabetes and age; inclusion of this imaging variable eliminated other traditional risk factors often found in stroke outcomes models. Outcome at 3 months was a significant predictor of long-term mortality and functional outcome. Black race was a predictor of 4-year mortality. Conclusions We propose that predictive models for stroke outcome, as well as analysis of clinical trials, should include adjustment for comorbid conditions. The effects of PVWMD on short-term functional outcomes and black race on long-term mortality are findings that require confirmation. PMID:19109548

To determine whether early life adversity (ELA) was predictive of inflammatory markers and to determine the consistency of these associations across racial groups. We analyzed data from 177 African Americans and 822 whites aged 35 to 86 years from two preliminary subsamples of the Midlife in the United States biomarker study. ELA was measured via retrospective self-report. We used multivariate linear regression models to examine the associations between ELA and C-reactive protein, interleukin-6, fibrinogen, endothelial leukocyte adhesion molecule-1, and soluble intercellular adhesion molecule-1, independent of age, gender, and medications. We extended race-stratified models to test three potential mechanisms for the observed associations. Significant interactions between ELA and race were observed for all five biomarkers. Models stratified by race revealed that ELA predicted higher levels of log interleukin-6, fibrinogen, endothelial leukocyte adhesion molecule-1, and soluble intercellular adhesion molecule-1 among African Americans (p < .05), but not among whites. Some, but not all, of these associations were attenuated after adjustment for health behaviors and body mass index, adult stressors, and depressive symptoms. ELA was predictive of high concentrations of inflammatory markers at midlife for African Americans, but not whites. This pattern may be explained by an accelerated course of age-related disease development for African Americans.

A Perceptual Pathway to Bias: Interracial Exposure Reduces Abrupt Shifts in Real-Time Race Perception That Predict Mixed-Race Bias.

In two national samples, we examined the influence of interracial exposure in one's local environment on the dynamic process underlying race perception and its evaluative consequences. Using a mouse-tracking paradigm, we found in Study 1 that White individuals with low interracial exposure exhibited a unique effect of abrupt, unstable White-Black category shifting during real-time perception of mixed-race faces, consistent with predictions from a neural-dynamic model of social categorization and computational simulations. In Study 2, this shifting effect was replicated and shown to predict a trust bias against mixed-race individuals and to mediate the effect of low interracial exposure on that trust bias. Taken together, the findings demonstrate that interracial exposure shapes the dynamics through which racial categories activate and resolve during real-time perceptions, and these initial perceptual dynamics, in turn, may help drive evaluative biases against mixed-race individuals. Thus, lower-level perceptual aspects of encounters with racial ambiguity may serve as a foundation for mixed-race prejudice. © The Author(s) 2016.

Since the 2000 Census, Asians and Pacific Islanders have been categorized as separate races. Government initiatives have called for greater study of Asian, Native Hawaiian, and other Pacific Islander (NHPI) health outcomes. NHPI often have worse health outcomes than Asians and Whites. Despite this, the lack of operationalization of racial definitions may affect the magnitude of health disparities. This analysis examined how utilizing different sociological race definitions could influence NHPI health outcomes when compared to Asians and Whites. Utilizing data from the 2009 California Health Interview Survey, NHPI had significantly higher age adjusted obesity prevalence than Whites under the UCLA Center for Health Policy Research (CHPR) (OR = 1.72, P = .03) and Self-Report (OR = 1.57, P = .01) definitions, but not the Census definition (OR = 1.42, P = .11). NHPI had significantly higher age adjusted obesity prevalence than Asians under all definitions (Census OR = 4.05, P < .01; CHPR OR = 4.81, P < .01; Self-Report OR = 4.46, P < .01). NHPI had significantly higher age adjusted diabetes/pre-diabetes prevalence than Whites across all definitions (Census OR = 3.27, P < .01, CHPR OR = 3.03, P < .01, Self-Report OR = 1.99, P = .01) but only the Census (OR = 2.12, P = .01) and CHPR (OR = 1.86, P = .04) when NHPI were compared to Asians. Overall, race definition changed the identification of health disparities. Future studies should operationalize racial definitions, as health disparities are masked post-hoc when utilizing different race definitions.

Rates of clinical diagnoses of schizophrenia in African American individuals appear to be elevated compared with other ethnic groups in the United States, contradicting population rates derived from epidemiologic surveys. To determine whether African American individuals would continue to exhibit significantly higher rates of clinical diagnoses of schizophrenia, even after controlling for age, sex, income, site, and education, as well as the presence or absence of serious affective disorder, as determined by experts blinded to race and ethnicity. A secondary objective was to determine if a similar pattern occurred in Latino subjects. Ethnicity-blinded and -unblinded diagnostic assessments were obtained in 241 African American individuals (mean [SD] age, 34.3 [8.1] years; 57% women), 220 non-Latino white individuals (mean [SD] age, 32.7 [8.5] years; 53% women), and 149 Latino individuals (mean [SD] age, 33.5 [8.0] years; 58% women) at 6 US sites. Logistic regression models were used to determine whether elevated rates of schizophrenia in African American individuals would persist after controlling for various confounding variables including blinded expert consensus diagnoses of serious affective illness. Six academic medical centers across the United States. Six hundred ten psychiatric inpatients and outpatients. Relative odds of unblinded clinical diagnoses of schizophrenia in African American compared with white individuals. A significant ethnicity/race effect (χ(2)(2)=10.4, P=.01) was obtained when schizophrenia was narrowly defined, controlling for all other predictors. The odds ratio comparing African American with non-Latino white individuals was significant (odds ratio=2.7; 95% CI, 1.5-5.1). Similar differences between African American and white individuals occurred when schizophrenia was more broadly defined (odds ratio=2.5; 95% CI, 1.4-4.5). African American individuals did not differ significantly from white individuals in overall severity of manic and

To determine if racial/ethnic disparities exist in the ownership of private long-term care insurance (LTCI) among current Medicare beneficiaries. This study used the 2011 wave of the National Health and Aging Trends Study. Bivariate analysis and multivariate logistic regression were employed to isolate the independent effects of race/ethnicity on LTCI uptake. Stratified multivariate analyses were used to further examine the effect of race/ethnicity on LTCI ownership. 12.3% of Blacks and 5.8% of Hispanics, compared with 20.2% of Whites (p < .001), reported having LTCI coverage. We found that Hispanics were 48% less likely to have LTCI (p = .005) compared with Whites, whereas no difference was found between Blacks and Whites. Compared with White women, Hispanic women were 81% less likely to be insured (p < .001). Ethnic disparities persisted among individuals who, based on income and assets, are considered appropriate for purchasing private LTCI coverage. This study demonstrates that ethnic differences exist in the ownership of LTCI among elderly Americans. Additional research is needed to determine what factors are responsible for the apparent underrepresentation of Hispanics in the LTCI market. © The Author 2013.

The aim of the study was to examine interactive relations of race and socioeconomic status (SES) to magnetic resonance imaging (MRI)-assessed global brain outcomes with previously demonstrated prognostic significance for stroke, dementia, and mortality. Participants were 147 African Americans (AAs) and whites (ages 33-71 years; 43% AA; 56% female; 26% below poverty) in the Healthy Aging in Neighborhoods of Diversity across the Life Span SCAN substudy. Cranial MRI was conducted using a 3.0 T unit. White matter (WM) lesion volumes and total brain, gray matter, and WM volumes were computed. An SES composite was derived from education and poverty status. Significant interactions of race and SES were observed for WM lesion volume (b = 1.38; η = 0.036; p = .028), total brain (b = 86.72; η = 0.042; p < .001), gray matter (b = 40.16; η = 0.032; p = .003), and WM (b = 46.56; η = 0.050; p < .001). AA participants with low SES exhibited significantly greater WM lesion volumes than white participants with low SES. White participants with higher SES had greater brain volumes than all other groups (albeit within normal range). Low SES was associated with greater WM pathology-a marker for increased stroke risk-in AAs. Higher SES was associated with greater total brain volume-a putative global indicator of brain health and predictor of mortality-in whites. Findings may reflect environmental and interpersonal stressors encountered by AAs and those of lower SES and could relate to disproportionate rates of stroke, dementia, and mortality.

Earlier research found evidence for electro-cortical race bias towards black target faces in white American participants irrespective of the task relevance of race. The present study investigated whether an implicit race bias generalizes across cultural contexts and racial in- and out-groups. An Australian sample of 56 Chinese and Caucasian males and females completed four oddball tasks that required sex judgements for pictures of male and female Chinese and Caucasian posers. The nature of the background (across task) and of the deviant stimuli (within task) was fully counterbalanced. Event-related potentials (ERPs) to deviant stimuli recorded from three midline sites were quantified in terms of mean amplitude for four components: N1, P2, N2 and a late positive complex (LPC; 350–700 ms). Deviants that differed from the backgrounds in sex or race elicited enhanced LPC activity. These differences were not modulated by participant race or sex. The current results replicate earlier reports of effects of poser race relative to background race on the LPC component of the ERP waveform. In addition, they indicate that an implicit race bias occurs regardless of participant’s or poser’s race and is not confined to a particular cultural context. PMID:21097957

The purpose of the study was to examine the relationships among emotional intelligence, teacher self-efficacy, length of teaching experience, and age in a sample of south Texas public school teachers. Additionally, the study examined differences in emotional intelligence between male teachers and female teachers, and among African American, Hispanics, and White teachers. Participants were 180 elementary science teachers from south Texas public schools. The sample was made up of 14 (7.8%) males and 166 (92.2%) females. Regarding race/ethnicity, the study sample consisted of 31 (17.2%) African Americans (3 males and 28 females), 49 (27.2) Hispanics (7 males and 42 females), 98 (54.4%) Whites (3 males and 95 females), and 2 (1.1%) "Other" (1 male and 1 female). Participants ranged in age from 23 years to 65 years. Five hypotheses were proposed and tested to address the relationships under investigation. The study employed a mixed methods---correlational and causal-comparative---research design approach. Three instruments, the Multifactor Emotional Intelligence Scale (Mayer, Caruso, & Salovey, 1999), the Science Teaching Efficacy Beliefs Instrument (Riggs & Enochs, 1990), and a demographics questionnaire were utilized to collect the data. An independent-measures t test, the Pearson r, and the one-way MANOVA were used to analyze the data. A Significant positive relationship was found between "emotional intelligence" and "teacher self-efficacy." Data analyses, however, failed to support hypothesized relationships between "emotional intelligence" and "length of teaching experience," and between "emotional intelligence" and "age". Additionally, statistical analyses of the data collected for this study supported predicted statistically significant differences in "emotional intelligence" between male and female teachers, and among the three race/ethnicity groupings. Based on these findings, recommendations for the application of the construct of "emotional intelligence" in

We examined which specific foods contributed to the atherogenic potential of diet in population segments defined by age, sex, educational attainment, and race/ethnicity. Data from the 1989 New York State Healthy Heart Program baseline survey were analyzed. This telephone survey was conducted in eight communities (total population approximately 1.24 million people) in New York State. Response rate was 65.5% (N = 4,179); 3,606 subjects ages 20 to 64 years who reported their level of educational attainment with self-described ethnicity of white (N = 1,935), black (N = 1,035), or Hispanic (N = 636) were retained in the analysis. Diet was assessed using a 17-item food frequency questionnaire which focused on commonly eaten food high in saturated fat and cholesterol. Connor's cholesterol/saturated-fat index was used as a scale of the atherogenic potential of the diet. Eggs, whole milk, cheese, beef, and butter/margarine were the foods contributing most to the cholesterol/saturated-fat index score in all age-, sex-, and race/ethnicity-specific population segments examined, together contributing a total of 52 to 72% of the cholesterol/saturated-fat index score as measured by the 17-item diet questionnaire. The implication for public health campaigns directed at reducing the atherogenic potential of diet atherogenicity and for primary care practitioners seeking to influence the diet of patients with high blood cholesterol is that substitutions of less atherogenic food choices for these five foods would appear to be appropriate for most adults.

Background. Poor self-esteem is a core element of depression. According to recent research, some racial groups may vary in the magnitude of the link between depression and poor self-esteem. Using a national sample, we compared Black and White older Americans for the effect of baseline depressive symptoms on decline in self-esteem over time. Methods. This longitudinal study used data from the Religion, Aging, and Health Survey, 2001⁻2004. The study followed 1493 older adults (734 Black and 759 White) 65 years or older for three years. Baseline depressive symptoms (CES-D), measured in 2001, was the independent variable. Self-esteem, measured at the end of the follow up, was the dependent variable. Covariates included baseline demographic characteristics (age and gender), socioeconomic factors (education, income, and marital status), health (self-rated health), and baseline self-esteem. Race/ethnicity was the moderator. Linear multi-variable regression models were used for data analyses. Results. In the pooled sample, higher depressive symptoms at baseline were predictive of a larger decline in self-esteem over time, net of covariates. We found a significant interaction between race/ethnicity and baseline depressive symptoms on self-esteem decline, suggesting a weaker effect for Blacks compared to Whites. In race/ethnicity-specific models, high depressive symptoms at baseline was predictive of a decline in self-esteem for Whites but not Blacks. Conclusion. Depressive symptoms may be a more salient contributor to self-esteem decline for White than Black older adults. This finding has implications for psychotherapy and cognitive behavioral therapy of depression of racially diverse populations.

Oxytocin eliminates the own-race bias in face recognition memory☆

The neuropeptide Oxytocin influences a number of social behaviors, including processing of faces. We examined whether Oxytocin facilitates the processing of out-group faces and reduce the own-race bias (ORB). The ORB is a robust phenomenon characterized by poor recognition memory of other-race faces compared to the same-race faces. In Experiment 1, participants received intranasal solutions of Oxytocin or placebo prior to viewing White and Black faces. On a subsequent recognition test, whereas in the placebo condition the same-race faces were better recognized than other-race faces, in the Oxytocin condition Black and White faces were equally well recognized, effectively eliminating the ORB. In Experiment 2, Oxytocin was administered after the study phase. The ORB resulted, but Oxytocin did not significantly reduce the effect. This study is the first to show that Oxytocin can enhance face memory of out-group members and underscore the importance of social encoding mechanisms underlying the own-race bias. PMID:23872107

Five thousand three hundred five World War II and Korean conflict veterans who have been compensated by the Veterans Administration for multiple sclerosis (MS) were matched to controls on the basis of age, date of entry into military service, and branch of service. Case/control ratios for white males, white females, and black males were 1.04, 1.86, and 0.45, respectively. The coterminous 48 states, divided into three tiers on the basis of latitude, exhibited the well-known north-south gradient in risk: For all races and both sexes, case/control ratios were 1.41, 1.00, and 0.53 for the North, Middle, and South tiers. Both white females and black males showed this same north-to-south variation in risk. The case/control ratio for males of races other than black or white was 0.23, with possible deficits in risk for American Indians and Japanese-Americans. Filipinos and Hawaiian Japanese were significantly low-risk groups. These findings suggest that both a racial and a possibly genetic predisposition, as well as a geographically determined differential exposure to an environmental agent, are related to the risk of MS.

Abstract Background Body image (BI) and body satisfaction may be important in understanding weight loss behaviors, particularly during the postpartum period. We assessed these constructs among African American and white overweight postpartum women. Methods The sample included 162 women (73 African American and 89 white) in the intervention arm 6 months into the Active Mothers Postpartum (AMP) Study, a nutritional and physical activity weight loss intervention. BIs, self-reported using the Stunkard figure rating scale, were compared assessing mean values by race. Body satisfaction was measured using body discrepancy (BD), calculated as perceived current image minus ideal image (BD<0: desire to be heavier; BD>0: desire to be lighter). BD was assessed by race for: BDIdeal (current image minus the ideal image) and BDIdeal Mother (current image minus ideal mother image). Results Compared with white women, African American women were younger and were less likely to report being married, having any college education, or residing in households with annual incomes >$30,000 (all p < 0.01). They also had a higher mean body mass index (BMI) (p = 0.04), although perceived current BI did not differ by race (p = 0.21). African Americans had higher mean ideal (p = 0.07) and ideal mother (p = 0.001) BIs compared with whites. African Americans' mean BDs (adjusting for age, BMI, education, income, marital status, and interaction terms) were significantly lower than those of whites, indicating greater body satisfaction among African Americans (BDIdeal: 1.7 vs. 2.3, p = 0.005; BDIdeal Mother: 1.1 vs. 1.8, p = 0.0002). Conclusions Racial differences exist in postpartum weight, ideal images, and body satisfaction. Healthcare providers should consider tailored messaging that accounts for these racially different perceptions and factors when designing weight loss programs for overweight mothers. PMID:20113143

Exercise is a modifiable lifestyle risk factor associated with prostate cancer risk reduction. However, whether this association is different as a function of race is unclear. In the current study, the authors attempted to characterize the link between exercise and prostate cancer (CaP) in white and black American men. Using a prospective design, 307 men (164 of whom were white and 143 of whom were black) who were undergoing prostate biopsy completed a self-reported survey that assessed exercise behavior (metabolic equivalent [MET] hours per week). Crude and adjusted logistic regression analyses were used to estimate the risk of prostate cancer controlling for age, body mass index, digital rectal examination findings, previous biopsy, Charlson comorbidity score, and family history of CaP stratified by self-reported race. There was no significant difference noted with regard to the amount of exercise between racial groups (P = .12). Higher amounts of MET hours per week were associated with a decreased risk of CaP for white men in both crude (P = .02) and adjusted (P = .04) regression models. Among whites, men who exercised ≥ 9 MET hours per week were less likely to have a positive biopsy result compared with men exercising < 9 MET hours per week (odds ratio, 0.47; 95% confidence interval, 0.22-0.99 [P = .047]). There was no association noted between MET hours per week and risk of CaP among black men in both crude (P = .79) and adjusted (P = .76) regression models. In a prospective cohort of men undergoing biopsy, increased exercise, measured as MET hours per week, was found to be associated with CaP risk reduction among white but not black men. Investigating race-specific mechanisms by which exercise modifies CaP risk and why these mechanisms disfavor black men in particular are warranted. Copyright © 2013 American Cancer Society.

White on black: can white parents teach black adoptive children how to understand and cope with racism?

PubMed

Smith, Darron T; Juarez, Brenda G; Jacobson, Cardell K

2011-01-01

In this article, the authors examine White parents’ endeavors toward the racial enculturation and inculcation of their transracially adopted Black children. Drawing on in-depth interviews, the authors identify and analyze themes across the specific race socialization strategies and practices White adoptive parents used to help their adopted Black children to develop a positive racial identity and learn how to effectively cope with issues of race and racism. The central aim of this article is to examine how these lessons about race help to connect family members to U.S. society’s existing racial hierarchy and how these associations position individuals to help perpetuate or challenge the deeply embedded and historical structures of White supremacy. The authors use the notion of White racial framing to move outside of the traditional arguments for or against transracial adoption to instead explore how a close analysis of the adoptive parents’ racial instructions may serve as a learning tool to foster more democratic and inclusive forms of family and community.

We examined the association between socioeconomic status (SES) discrimination and C-reactive protein (CRP) in a biracial cohort of middle-aged adults using an intersectionality framework. Participants were 401 African-American and White adults from a population-based cohort in the Southeastern United States. SES discrimination was self-reported with a modified Experiences of Discrimination Scale, and CRP levels were assayed from blood samples. Linear regression analyses were used to examine the associations among SES discrimination, race, education, and CRP after controlling for age, gender, racial and gender discrimination, financial and general stress, body mass index, smoking, sleep quality, and depressive symptoms. Intersectional effects were tested using race×SES discrimination, education×SES discrimination and race×education×SES discrimination interactions. Adjusting for sociodemographics, racial discrimination, gender discrimination, and all relevant two-way interaction terms, we observed a significant race×education×SES discrimination interaction (p=0.019). In adjusted models stratified by race and education, SES discrimination was associated with elevated CRP among higher educated African-Americans (β=0.29, p=0.018), but not lower educated African-Americans (β=-0.13, p=0.32); or lower educated (β=-0.02, p=0.92) or higher educated (β=-0.01, p=0.90) Whites. Findings support the relevance of SES discrimination as an important discriminatory stressor for CRP specifically among higher educated African-Americans. Copyright © 2017 Elsevier Ltd.

2018-05-01

Minorities’ Diminished Return theory suggests that health effects of socioeconomic status (SES) are systemically smaller for racial and ethnic minorities compared to Whites. To test the relevance of Minorities’ Diminished Return theory for youth impulsivity, we investigated Black⁻White differences in the effects of family SES at birth on subsequent youth impulsivity at age 15. Data came from the Fragile Families and Child Wellbeing Study (FFCWS), 1998⁻2016, a 15-year longitudinal study of urban families from the birth of their children to age 15. This analysis included 1931 families who were either White ( n = 495) or Black ( n = 1436). The independent variables of this study were family income, maternal education, and family structure at birth. Youth impulsivity at age 15 was the dependent variable. Gender was the covariate and race was the focal moderator. We ran linear regressions in the overall sample and specific to each race. In the overall sample, higher household income (b = −0.01, 95% CI = −0.01 to 0.00) and maternal education (b = −0.24, 95% CI = −0.44 to −0.04) at birth were associated with lower youth impulsivity at age 15, independent of race, gender, and family structure. A significant interaction was found between race and household income at birth (b = 0.01, 95% CI = 0.00 to 0.02) on subsequent youth impulsivity, which was indicative of a stronger protective effect for Whites compared to Blacks. Blacks’ diminished return exists for the long-term protective effects of family income at birth against subsequent youth impulsivity. The relative disadvantage of Blacks in comparison to Whites is in line with a growing literature showing that Black families gain less from high SES, which is possibly due to the existing structural racism in the US.
