RESUMEN
Multiracial people report higher mean Adverse Childhood Experiences (ACEs) scores and prevalence of anxiety than other racial groups. Studies using statistical interactions to estimate racial differences in ACEs-anxiety associations do not show stronger associations for Multiracial people. Using data from Waves 1 (1995-97) through 4 (2008-09) of the National Longitudinal Study of Adolescent to Adult Health (Add Health), we simulated a stochastic intervention over 1,000 resampled datasets to estimate the race-specific cases averted per 1,000 of anxiety if all racial groups had the same exposure distribution of ACEs as Whites. Simulated cases averted were greatest for the Multiracial group, (median = -4.17 cases per 1,000, 95% CI: -7.42, -1.86). The model also predicted smaller risk reductions for Black participants (-0.76, 95% CI: -1.53, -0.19). CIs around estimates for other racial groups included the null. An intervention to reduce racial disparities in exposure to ACEs could help reduce the inequitable burden of anxiety on the Multiracial population. Stochastic methods support consequentialist approaches to racial health equity, and can encourage greater dialogue between public health researchers, policymakers, and practitioners.
RESUMEN
An abundance of research has documented health inequalities by race and socioeconomic position (SEP) in the United States. However, conceptual and methodological challenges complicate the interpretation of study findings, thereby limiting progress in understanding health inequalities and in achieving health equity. Fundamental to these challenges is a lack of clarity about what race is and the implications of that ambiguity for scientific inquiry. Additionally, there is wide variability in how SEP is conceptualized and measured, resulting in a lack of comparability across studies and significant misclassification of risk. The objectives of this review are to synthesize the literature regarding common approaches to examining race and SEP health inequalities and to discuss the conceptual and methodological challenges associated with how race and SEP have been employed in public health research. Addressing health inequalities has become increasingly important as the United States trends toward becoming a majority-minority nation. Recommendations for future research are presented.

Racial discrimination is conceptualized as a psychosocial stressor that has negative implications for mental health. However, factors related to racial identity may influence whether negative experiences are interpreted as instances of racial discrimination and subsequently reported as such in survey instruments, particularly given the ambiguous nature of contemporary racism. Along these lines, dimensions of racial identity may moderate associations between racial discrimination and mental health outcomes. This study examined relationships between racial discrimination, racial identity, implicit racial bias, and depressive symptoms among African American men between 30 and 50 years of age (n = 95). Higher racial centrality was associated with greater reports of racial discrimination, while greater implicit anti-Black bias was associated with lower reports of racial discrimination. In models predicting elevated depressive symptoms, holding greater implicit anti-Black bias in tandem with reporting lower racial discrimination was associated with the highest risk. Results suggest that unconscious as well as conscious processes related to racial identity are important to consider in measuring racial discrimination, and should be integrated in studies of racial discrimination and mental health.
RESUMEN
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.

OBJECTIVES: Empirical findings on racial discrimination and hypertension risk have been inconsistent. Some studies have found no association between self-reported experiences of discrimination and cardiovascular health outcomes, whereas others have found moderated or curvilinear relationships. The current cross-sectional study examined whether the association between racial discrimination and hypertension is moderated by implicit racial bias among African American midlife men. METHODS: This study examined the data on 91 African American men between 30 and 50 years of age. Primary variables were self-reported experiences of racial discrimination and unconscious racial bias as measured by the Black-White Implicit Association Test. Modified Poisson regression models were specified, examining hypertension, defined as a mean resting systolic level of at least 140 mm Hg or diastolic level of at least 90 mm Hg, or self-reported history of cardiovascular medication use with a physician diagnosis of hypertension. RESULTS: No main effects for discrimination or implicit racial bias were found, but the interaction of the two variables was significantly related to hypertension (χ(2)(1) = 4.89, p < .05). Among participants with an implicit antiblack bias, more frequent reports of discrimination were associated with a higher probability of hypertension, whereas among those with an implicit problack bias, it was associated with lower risk. CONCLUSIONS: The combination of experiencing racial discrimination and holding an antiblack bias may have particularly detrimental consequences on hypertension among African American midlife men, whereas holding an implicit problack bias may buffer the effects of racial discrimination. Efforts to address both internalized racial bias and racial discrimination may lower cardiovascular risk in this population.

Young Mexican-American women are disproportionately affected by teen pregnancy and early childbearing. While many of the studies that have investigated this population's high risk for early childbearing have focused predominantly on micro-level factors, a growing body of research has demonstrated the importance of neighborhood-level factors in shaping risk for this outcome. In order to elucidate the role of neighborhood context with regards to early childbearing among adolescent Mexican-American women, it is important to understand what these young women consider to be their neighborhood context and how they experience these contexts. This study utilized a mixed-methods design incorporating participatory photography, photo-elicitation, and focus groups in order to gain a more nuanced understanding of how neighborhood context is conceptualized and experienced by Mexican-American young women, and how these experiences may influence risk for early childbearing. Major findings include: (1) participants view the blocks on which they live as their neighborhood, but their exposure to neighborhood context extends beyond these blocks and includes the transient spaces they move through daily; and (2) within their neighborhood contexts, participants are influenced by experiences of discrimination and the presence of gangs and violence. These findings point to the importance of neighborhood-level factors in the lives of adolescent Mexican-American women, and may be used to inform future studies looking at the role of neighborhood context in shaping risk for early childbearing among this population.

Evidence of the association between income inequality and mortality has been mixed. Studies indicate that growing income inequalities reflect inequalities between, rather than within, racial groups. Racial segregation may play a role. We examine the role of racial segregation on the relationship between income inequality and mortality in a cross-section of US metropolitan areas. Metropolitan areas were included if they had a population of at least 100,000 and were at least 10% black (N = 107). Deaths for the time period 1991-1999 were used to calculate age-adjusted all-cause mortality rates for each metropolitan statistical area (MSA) using direct age-adjustment techniques. Multivariate least squares regression was used to examine associations for the total sample and for blacks and whites separately. Income inequality was associated with lower mortality rates among whites and higher mortality rates among blacks. There was a significant interaction between income inequality and racial segregation. A significant graded inverse income inequality/mortality association was found for MSAs with higher versus lower levels of black-white racial segregation. Effects were stronger among whites than among blacks. A positive income inequality/mortality association was found in MSAs with higher versus lower levels of Hispanic-white segregation. Uncertainty regarding the income inequality/mortality association found in previous studies may be related to the omission of important variables such as racial segregation that modify associations differently between groups. Research is needed to further elucidate the risk and protective effects of racial segregation across groups.

OBJECTIVE: We examined black-white differences in activities of daily living (ADLs), functional limitations (FLs), vision/hearing/sensory impairment, and memory/learning problems in a large, nationally representative sample of community-dwelling and institutionalized people across the lifespan. METHODS: Data are from the 2006 American Community Survey (n=2,288,800). We included data on non-Hispanic black respondents (125,985 males and 145,780 females) and non-Hispanic white respondents (977,792 males and 1,039,243 females) ≥5 years of age. We used logistic regression to examine the black-white odds for each disability outcome. The overall response rate was 97.5%. RESULTS: For FLs, ADL limitations, and memory/learning problems, black people experienced higher odds of disability across the adult lifespan compared with white people. Black-white differences narrowed in older age. For vision/hearing problems, a black-white crossover was found in older age (≥85 years), where odds of vision/hearing problems were lower among black people than among white people. For all disability outcomes, black-white differences peaked in midlife (50-69 years of age), with black people having approximately 1.5 to two times the odds of disabilities as their white peers. CONCLUSIONS: The study findings suggest the need to address black-white disparities across a range of disability outcomes throughout the lifespan. Future work identifying the factors accounting for this pattern of disparities will help inform the development of appropriate prevention strategies.

BACKGROUND: African American men in the USA experience poorer aging-related health outcomes compared to their White counterparts, partially due to socioeconomic disparities along racial lines. Greater exposure to socioeconomic strains among African American men may adversely impact health and aging at the cellular level, as indexed by shorter leukocyte telomere length (LTL). This study examined associations between socioeconomic factors and LTL among African American men in midlife, a life course stage when heterogeneity in both health and socioeconomic status are particularly pronounced. METHODS: Using multinomial logistic regression, we examined associations between multiple measures of SES and tertiles of LTL in a sample of 92 African American men between 30 to 50 years of age. RESULTS: Reports of greater financial strain were associated with higher odds of short versus medium LTL (odds ratio (OR)=2.21, p = 0.03). Higher income was associated with lower odds of short versus medium telomeres (OR=0.97, p = 0.04). Exploratory analyses revealed a significant interaction between educational attainment and employment status (χ 2 = 4.07, p = 0.04), with greater education associated with lower odds of short versus long telomeres only among those not employed (OR=0.10, p = 0.040). CONCLUSION: Cellular aging associated with multiple dimensions of socioeconomic adversity may contribute to poor aging-related health outcomes among African American men. Subjective appraisal of financial difficulty may impact LTL independently of objective dimensions of SES. Self-appraised success in fulfilling traditionally masculine gender roles, including being an economic provider, may be a particularly salient aspect of identity for African American men and have implications for cellular aging in this population.

African American men in the US experience disparities across multiple health outcomes. A common mechanism underlying premature declines in health may be accelerated biological aging, as reflected by leukocyte telomere length (LTL). Racial discrimination, a qualitatively unique source of social stress reported by African American men, in tandem with poor mental health, may negatively impact LTL in this population. The current study examined cross-sectional associations between LTL, self-reported racial discrimination, and symptoms of depression and anxiety among 92 African American men 30-50 years of age. LTL was measured in kilobase pairs using quantitative polymerase chain reaction assay. Controlling for sociodemographic factors, greater anxiety symptoms were associated with shorter LTL (b=-0.029, standard error [SE]=0.014; p<0.05). There were no main effects of racial discrimination or depressive symptoms on LTL, but we found evidence for a significant interaction between the two (b=0.011, SE=0.005; p<0.05). Racial discrimination was associated with shorter LTL among those with lower levels of depressive symptoms. Findings from this study highlight the role of social stressors and individual-level psychological factors for physiologic deterioration among African American men. Consistent with research on other populations, greater anxiety may reflect elevated stress associated with shorter LTL. Racial discrimination may represent an additional source of social stress among African American men that has detrimental consequences for cellular aging among those with lower levels of depression.

BACKGROUND: Leukocyte telomere length (LTL) is an indicator of general systemic aging, with shorter LTL being associated with several chronic diseases of aging and earlier mortality. Identifying factors related to LTL among African Americans may yield insights into mechanisms underlying racial disparities in health. PURPOSE: To test whether the combination of more frequent reports of racial discrimination and holding a greater implicit anti-black racial bias is associated with shorter LTL among African-American men. METHODS: Cross-sectional study of a community sample of 92 African-American men aged between 30 and 50 years. Participants were recruited from February to May 2010. Ordinary least squares regressions were used to examine LTL in kilobase pairs in relation to racial discrimination and implicit racial bias. Data analysis was completed in July 2013. RESULTS: After controlling for chronologic age and socioeconomic and health-related characteristics, the interaction between racial discrimination and implicit racial bias was significantly associated with LTL (b=-0.10, SE=0.04, p=0.02). Those demonstrating a stronger implicit anti-black bias and reporting higher levels of racial discrimination had the shortest LTL. Household income-to-poverty threshold ratio was also associated with LTL (b=0.05, SE=0.02, p<0.01). CONCLUSIONS: Results suggest that multiple levels of racism, including interpersonal experiences of racial discrimination and the internalization of negative racial bias, operate jointly to accelerate biological aging among African-American men. Societal efforts to address racial discrimination in concert with efforts to promote positive in-group racial attitudes may protect against premature biological aging in this population.

PURPOSE: To examine associations between racial discrimination, mood disorders, and cardiovascular disease (CVD) among Black Americans. METHODS: Weighted logistic regression analyses were performed on a nationally representative sample of Black Americans (n = 5022) in the National Survey of American Life (NSAL; 2001-2003). Racial discrimination and CVD were assessed via self-report. Mood disorder was measured with the World Health Organization Composite International Diagnostic Interview. RESULTS: Model-adjusted risk ratios (RRs) revealed that participants with a history of mood disorder had greater risk of CVD (RR, 1.28; 95% confidence interval (CI), 1.12-1.45). This relationship was found specifically among those younger than 50 years of age (RR, 1.56; 95% CI, 1.27-1.91). There was a significant interaction between racial discrimination and mood disorder in predicting CVD in the total (F = 2.86, 3 df, p = .047) and younger sample (F = 2.98, 3 df, p = .047). Participants with a history of mood disorder who reported high levels of racial discrimination had the greatest risk of CVD. CONCLUSIONS: The association between racial discrimination and CVD is moderated by history of mood disorder. Future studies may examine pathways through which racial discrimination and mood disorders impact CVD risk among Black Americans.

BACKGROUND: Socioeconomically disadvantaged children have poorer physical and mental health and lower social and school/academic functioning compared to children with higher socioeconomic status (SES). These associations are not static but may vary by choice of SES indicator and child race/ethnicity. However, little is known about these associations in middle-childhood, a distinct and critical developmental period. We explore these associations in a small exploratory study designed to examine associations between SES and child developmental outcomes in middle childhood. MATERIALS AND METHODS: We recruited 60 families with a child between 8-12 years of age from the San Francisco Bay area September 2005-June 2006. The MacArthur Health and Behavior Questionnaire was used to assess health and adaptive functioning across four developmental domains: physical health, mental health, social functioning, and school/academic functioning. We examined a range of SES measures including continuous and categorical assessments of poverty, income, wealth, maternal and overall family educational attainment, subjective social status, and cumulative social risk. A series of multivariate ordinary least squares regressions was performed on the total sample and within race-specific groups. RESULTS: Although the long-recognized, graded relations among SES and outcomes were present, associations employing categorical representations of SES were far more pervasive; and stronger in magnitude. Wealth and highest degree earned in the family showed the strongest associations across virtually all health/functioning domains. Health and functioning was more strongly associated with educational attainment among Whites and financial resources among Blacks. Among Whites more wealth was associated with worse outcomes. CONCLUSIONS: Further research is needed to confirm the study findings. However, this study raises important questions about the measurement of SES for studying disparities in child health and developmental outcomes. This initial research suggests that improvements in health and functioning in middle childhood may require more significant status transitions; more targeted social interventions to address racial/ethnic disparities in child health and developmental outcomes; and a need to intervene on adversities facing affluent youth, a potentially hidden yet vulnerable group in middle childhood.
