Stress-Related Biosocial Mechanisms of Discrimination and African American Health Inequities

Associations between adolescent perceived loneliness and hair cortisol concentration

INTRODUCTION

Adolescents experience high levels of loneliness, which is linked to poor health in adulthood. Loneliness may contribute to poor health through chronic dysregulation of the hypothalamic-pituitary-adrenal axis. In this analysis, we examined the associations between survey- and ecological momentary assessment (EMA)-based measures of loneliness and hair cortisol concentrations (HCC) in a sample of 1102 adolescents and assessed sex differences in this relationship.

METHODS

Data came from wave 1 of the Adolescent Health and Development in Context study. We conducted a series of multivariable linear regression models to examine the associations between loneliness and HCC. Models were adjusted for adolescent and caregiver demographics, adolescent clinical factors, adolescent hair care practices, and adolescent lifetime mental health diagnosis and current psychotropic medication use. An interaction term between sex and loneliness was added to assess for effect moderation.

RESULTS

In our sample, the mean HCC was 1.35 pg/mg (SD=1.1). The mean for the unstandardized survey loneliness measure was 1.79 (SD=0.79) for the total analytic sample. The unstandardized mean for the EMA loneliness measure was - 0.02 (SD=2.1) for the total analytic sample. In model one testing the bivariate linear relationship between loneliness and HCC, higher loneliness via survey and EMA measures was associated with lower HCC (Survey: b= - 0.10, SE=0.03, p=.004; EMA: b= - 0.09, SE=0.03, p=.005). In model two, higher loneliness remained significantly associated with lower HCC (Survey: b= - 0.07, SE=0.03, p=.023; EMA: b= - 0.07, SE=0.03, p=.037), after controlling for the following covariates: sociodemographic factors, pubertal development and BMI, corticosteroid use, hair care practices, season of collection and assayed hair length. In model 3, youth lifetime mental health diagnosis and current psychotropic medication use were added into the regression model, and higher loneliness remained significantly associated with lower HCC (Survey: b= - 0.07, SE=0.03, p=.029; EMA: b= - 0.07, SE=0.03, p=.039). There was no effect modification by sex (Survey: b=0.04, SE=0.06, p=.552; EMA: b= - 0.01, SE=0.06, p=.843).

CONCLUSIONS

In our analysis, both survey- and EMA-reported loneliness measures were associated with lower HCC. No evidence of an interaction between sex and loneliness was observed. Future research is needed to validate these findings and investigate longitudinal relationships among adolescent loneliness, stress physiology, and downstream health sequelae.

Death of a Parent, Racial Inequities, and Cardiovascular Disease Risk in Early to Mid-adulthood

Black Americans experience the death of a parent much earlier in the life course than White Americans on average. However, studies have not considered whether the cardiovascular health consequences of early parental death vary by race. Using data from the National Longitudinal Study of Adolescent to Adult Health, we explore associations between early parental death and cardiovascular disease (CVD) risk in early to mid-adulthood (N = 4,193). We find that the death of a parent during childhood or adolescence (ages 0-17) or the transition to adulthood (ages 18-27) is associated with increased CVD risk for Black Americans, whereas parental death following the transition to adulthood (ages 28+) undermines cardiovascular health for both Black Americans and White Americans. These findings illustrate how a stress and life course perspective can help inform strategies aimed at addressing both the unequal burden of bereavement and high cardiovascular risk faced by Black Americans.

Neighborhood Disadvantage and Prostate Tumor Aggressiveness among African American and European American Men

BACKGROUND

Studies have identified associations between neighborhood disadvantage (ND), which is more likely to affect African American (AA) individuals, and aggressive prostate cancer. Thus, ND may contribute to prostate cancer disparities. However, it is unknown what ND components drive aggressive disease and whether associations vary by race.

METHODS

We evaluated associations between aggressive prostate cancer and four ND metrics-Area Deprivation Index (ADI), validated Bayesian Neighborhood Deprivation Index (NDI), racial isolation (RI) index, and historical redlining, and whether these factors interacted with race, among men with prostate cancer treated at the University of Maryland Greenebaum Comprehensive Cancer Center (2004-2021).

RESULTS

We included 1,458 men (698 European American and 760 AA). AA men were more likely to experience ND. In adjusted models, the ADI, RI, and redlining were significantly associated with aggressive versus nonaggressive prostate cancer overall [ADI, OR for one SD increase = 1.14, 95% confidence interval (CI), 1.00-1.30; RI, OR = 1.27, CI, 1.07-1.51; redlining, OR = 1.77; CI, 1.23-2.56] and among AA men. The NDI was associated with aggressive prostate cancer among AA men (OR = 1.32, 95% credible interval: 1.13-1.57); percent in poverty received the largest importance weight. The ADI (P heterogeneity = 0.002) and NDI (exceedance probability heterogeneity = 98.1%) significantly interacted with race, such that associations were significantly stronger for AA men.

CONCLUSIONS

We identified novel significant positive associations for racial segregation and historical redlining with aggressive prostate cancer and significant interactions between ND indices and race.

IMPACT

Findings inform specific ND components that are associated with aggressive prostate cancer and suggest the ND effect is stronger for AA men, which has implications for interventions to reduce disparities.

The Effect of Multicultural Attitudes and Perceived Intergroup Threat on Attitudes Towards Immigrants in Portugal: A Polynomial Regression With Response Surface Analysis

Supported by the Intergroup Threat Theory (ITT), this study analyzes the effect of multicultural ideology on attitudes towards immigrants mediated by realistic, symbolic, and zero-sum threats. With a sample of Portuguese participants (N = 404)), polynomial regression analysis with response surface methodology was used to test the effects of multicultural attitude (MA) and perceived intergroup threat (PIT) on attitudes towards immigrants (ATI). This study also tested a model in which positive MA leads to a lower PIT, and consequently to more favorable ATI. Four hypotheses were proposed; all of which were confirmed. The results further showed that the direction of discrepancy between MA and PIT can provide a more comprehensive understanding of the complex role of multicultural ideology in predicting ATI. Findings, limitations, and directions for future research are discussed.

Reexamining the causes of age patterns in Black-White birth weight disparities: Evidence from U.S. cohorts

Black-White disparities in low birth weight (LBW) rise with maternal age. Why? The "weathering hypothesis" holds that the increasing disparity is due to the accumulation of adverse exposures leading to accelerated aging among Black compared to White mothers. Using US birth certificate data covering millions of births to successive cohorts of US women, this paper finds two sets of results that complicate this theory. Descriptively, I find that Black-White LBW disparities increase with age for some cohorts but not others. More causally, analyses exploiting a plausibly exogenous policy shock show that the effects of reducing adverse exposures were larger for older compared to younger mothers. This evidence points toward an alternative or complementary hypothesis: that LBW risks are more responsive to adverse exposures at older maternal ages than at younger ages. Emphasizing this pathway -- what I call "responsiveness" -- as opposed to accumulation has important implications for both research and policy.

Beyond Acculturation: Health and Immigrants' Social Integration in the United States

Immigrants typically have more favorable health outcomes than their U.S.-born counterparts of the same race-ethnicity. However, little is known about how race-ethnicity and region of birth moderate the health outcomes of different immigrant groups as their tenure of U.S. residence increases. We study the association between time spent in the United States and health outcomes among non-Hispanic Black, non-Hispanic White, Asian, and Hispanic immigrants using National Health Interview Survey data. Although all immigrant groups initially report better health outcomes than their U.S.-born counterparts, the association between U.S. tenure and reported health outcomes varies among immigrants by race-ethnicity and region of birth. Black immigrants have the worst hypertension profiles, and Black and Hispanic immigrants have the worst obesity profiles. The results suggest that acculturation cannot fully explain racial-ethnic differences in the association between U.S. tenure and health outcomes. We advance a more complete sociological theory of immigrant integration to better explain disparate immigrant health profiles.

A closer examination of the "rural mortality penalty": Variability by race, region, and measurement

BACKGROUND

Racial health disparities are well documented and pervasive across the United States. Evidence suggests there is a "rural mortality penalty" whereby rural residents experience poorer health outcomes than their urban counterparts. However, whether this penalty is uniform across demographic groups and U.S. regions is unknown.

OBJECTIVE

To assess how rural-urban differences in mortality differ by race (Black vs. White), U.S. region, poverty status, and how rural-urban status is measured.

METHODS

Age-standardized mortality rates (ASMRs)/100,000 by U.S. county (2015-2019) were obtained by race (Black/White) from the CDC Wonder National Vital Statistics System (2015-2019) and were merged with county-level social determinants from the US Census Bureau and County Health Rankings. Multivariable generalized linear models assessed the associations between rurality (index of relative rurality [IRR] decile, rural-urban continuum codes, and population density) and race-specific ASMR, overall, and by Census region and poverty level.

RESULTS

Overall, average ASMR was significantly higher in rural areas than urban areas for both Black (rural ASMR = 949.1 per 100,000 vs. urban ASMR = 857.7 per 100,000) and White (rural ASMR = 903.0 per 100,000 vs. urban ASMR = 791.6 per 100,000) populations. The Black-White difference was substantially higher (p < 0.001) in urban than in rural counties (65.1 per 100,000 vs. 46.1 per 100,000). Black-White differences and patterns in ASMR varied notably by poverty status and U.S. region.

CONCLUSION

Policies and interventions designed to reduce racial health disparities should consider and address key contextual factors associated with geographic location, including rural-urban status and socioeconomic status.

The physiological toll of arrests: An examination of arrest history on midlife allostatic load

PURPOSE

To understand how allostatic load - cumulative physiologic burden of stress - varies by amount and timing of arrests stratified by race/ethnicity and by sex.

METHODS

Using The National Longitudinal Study of Adolescent to Adult Health, we calculated descriptive statistics and mean differences in bio-marker measured allostatic load by arrest history stratified by race/ethnicity and sex.

RESULTS

One-third of participants experienced at least one arrest, and most experienced arrests only as adults. Allostatic load scores were higher for those that had ever experienced an arrest compared to never (mean difference: 0.58 (0.33, 0.84)). Similar results held for men and women and across race/ethnicity, but Black non-Hispanic individuals had higher allostatic load at all levels compared to other individuals.

CONCLUSIONS

Experiencing both any arrest and multiple arrests were associated with higher allostatic load. The stress of arrests may contribute to physiological maladaptations and poor health. The public health and law enforcement fields must recognize the detrimental consequences of arrests on physiological stress and search for non-carceral solutions.

Intervening to reduce sedentary behavior among African American elders: the "Stand Up and Move More" intervention

Background

Reducing sedentary behavior is a promising intervention target for improving health for older adults; however, few interventions include African American communities. The purpose of this research was to extend the reach of an effective sedentary behavior intervention to African American elders.

Methods

Two pilot studies assessed the feasibility (retention, adherence, and safety) and acceptability (participant and leader perspectives) of a 4-wk "Stand Up and Move More" (SUMM) intervention. Sedentary behavior (self-reported and monitor-derived), function (short physical performance battery), and quality of life (SF-36) were measured at baseline (wk0), postintervention (wk4), and follow up (wk12; study 1) to examine preliminary effectiveness of the intervention. Participants (N=26) attended SUMM or an attention-matched stress management intervention (study 2). The magnitude of treatment effects were determined using Hedge's g effect size calculations [small (g=0.20 to 0.49), moderate (g=0.50 to 0.79), large (g>0.80)].

Results

Retention and adherence rates ranged from 50%-100% and 80%-100%, respectively. There were no adverse events. Participants expressed high satisfaction, and the leader of the SUMM intervention indicated that the intervention content was beneficial. Hedges' g revealed negligible to small changes in sedentary behavior (g<0.50) following SUMM. There were moderate to large improvements in function (g=0.51-0.82) and quality of life (g=0.54-1.07) from wk0 to wk4 in study 1; and moderate to large improvements in function (g=0.51-0.88) from wk0 to wk4 in study 2. There was a moderate improvement in quality of life (SF-36 emotional role limitations g=0.54) in the SUMM group only.

Conclusion

Given its feasibility, safety, and acceptability, SUMM may be a promising intervention to improve functioning and well-being among African American elders.

The mediating role of systemic inflammation and moderating role of racialization in disparities in incident dementia

BACKGROUND

Exposure to systemic racism is linked to increased dementia burden. To assess systemic inflammation as a potential pathway linking exposure to racism and dementia disparities, we investigated the mediating role of C-reactive protein (CRP), a systemic inflammation marker, and the moderating role of the racialization process in incident dementia.

METHODS

In the US Health and Retirement Study (n = 6,908), serum CRP was measured at baseline (2006, 2008 waves). Incident dementia was classified by cognitive tests over a six-year follow-up. Self-reported racialized categories were a proxy for exposure to the racialization process. We decomposed racialized disparities in dementia incidence (non-Hispanic Black and/or Hispanic vs. non-Hispanic white) into 1) the mediated effect of CRP, 2) the moderated portion attributable to the interaction between racialized group membership and CRP, and 3) the controlled direct effect (other pathways through which racism operates).

RESULTS

The 6-year cumulative incidence of dementia is 12%. Among minoritized participants (i.e., non-Hispanic Black and/or Hispanic), high CRP levels ( ≥ 75th percentile or 4.73μg/mL) are associated with 1.26 (95%CI: 0.98, 1.62) times greater risk of incident dementia than low CRP ( < 4.73μg/mL). Decomposition analysis comparing minoritized versus non-Hispanic white participants shows that the mediating effect of CRP accounts for 3% (95% CI: 0%, 6%) of the racial disparity, while the interaction effect between minoritized group status and high CRP accounts for 14% (95% CI: 1%, 27%) of the disparity. Findings are robust to potential violations of causal mediation assumptions.

CONCLUSIONS

Minoritized group membership modifies the relationship between systemic inflammation and incident dementia.

Associations of DNA-methylation measures of biological aging with social disparities in child and adolescent mental health

Children who experience environmental adversities are at increased risk of both internalizing and externalizing disorders. Epigenetic mechanisms may regulate the influence of environmental adversities on mental health. We examined the hypothesis that salivary DNA-methylation patterns of pace of biological aging (DunedinPoAm) and inflammation (DNAm-CRP) are socially stratified and associated with mental health in 1,183 children (609 female, age M=13.6y) from the Texas Twin Project. Analyses were preregistered. Participants' DNA-methylation algorithms and psychiatric symptoms differed by socioeconomic contexts and race/ethnicity. Children with more parent-reported internalizing symptoms had higher DunedinPoAm and DNAm-CRP scores, and children with more aggression problems had higher DNAm-CRP. DunedinPoAm partially mediated advantage of White racial identity on internalizing. Similarly, DNAm-CRP partially mediated advantage of higher family socioeconomic contexts and, in a separate model, White racial identity on reduced internalizing symptoms. Children's epigenetic measures of pace of biological aging and inflammation are associated with social inequalities and mental health.

Accumulating burden: Exposure to interpersonal discrimination based on multiple attributes and allostatic load

Exposure to interpersonal discrimination is an acute type of social stressor. Extant evidence suggests a positive association exists between experiencing interpersonal discrimination and physiological dysregulation measured by allostatic load. However, research to date has overlooked the role of exposure to interpersonal discrimination based on multiple attributes. This is an important oversight because individuals who confront discrimination often accredit the experiences to more than one attribute, which may be associated with increased stress and adverse physiological functioning. Using data from the Wave V biomarker subsample of the National Longitudinal Study of Adolescent to Adult Health (Add Health), I investigate the relationship between reports of interpersonal discrimination based on multiple attributes and allostatic load among adults ages 33-44. I also consider the roles of frequency of exposure to discrimination and perceived stress in this relationship through moderation and mediation analyses. Results reveal a positive association between the number of forms of discrimination that individuals report and allostatic load. However, frequency of exposure to discrimination does not moderate this association. Moreover, frequency of discrimination did not mediate the association between the number of forms of discrimination and perceived stress only marginally mediated it. This study offers novel and important insight into the role of exposure to more than one form of discrimination and allostatic load. Given that heightened allostatic load is a precursor to the development of chronic conditions and a strong risk factor for mortality, efforts to reduce discrimination among Americans adults will work to improve physical health.

Institutional Context Shapes the Physical Health of College Graduates Differently for U.S. White, Black, and Hispanic Adults

Greater educational attainment is generally associated with healthier and longer lives. However, important heterogeneity in who benefits from educational attainment, how much, and why remains underexplored. In particular, in the United States, the physical health returns to educational attainment are not as large for minoritized racial and ethnic groups compared with individuals racialized as White. Yet, our current understanding of ethnoracial differences in educational health disparities is limited by an almost exclusive focus on the quantity of education attained without sufficient attention to heterogeneity within educational attainment categories, such as different institution types among college graduates. Using biomarker data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), we test whether the physical health of college graduates in early adulthood (aged 24-32) varies by institution type and for White, Black, and Hispanic adults. In considering the role of the college context, we conceptualize postsecondary institutions as horizontally stratified and racialized institutional spaces with different implications for the health of their graduates. Finally, we quantify the role of differential attendance at and returns to postsecondary institution type in shaping ethnoracialized health disparities among college graduates in early adulthood.

Discrimination and perinatal depressive symptoms: The protective role of social support and resilience

BACKGROUND

Discrimination is an important social determinant of perinatal depression; however, evidence is limited regarding modifiable social and psychological factors that may moderate this association. We examined whether social support and resilience could protect against the adverse effects of discrimination on perinatal depressive symptoms.

METHODS

Pregnant people (N = 589) receiving Expect With Me group prenatal care in Nashville, TN and Detroit, MI completed surveys during third trimester of pregnancy and six months postpartum. Linear regression models tested the association between discrimination and depressive symptoms, and the moderating effects of social support and resilience, during pregnancy and postpartum.

RESULTS

The sample was predominantly Black (60.6 %), Hispanic (15.8 %) and publicly insured (71 %). In multivariable analyses, discrimination was positively associated with depressive symptoms during pregnancy (B = 4.44, SE = 0.37, p ≤0.001) and postpartum (B = 3.78, SE = 0.36, p < 0.001). Higher social support and resilience were associated with less depressive symptoms during pregnancy (B = -0.49, SE = 0.08, p < 0.001 and B = -0.67, SE = 0.10, p < 0.001, respectively) and postpartum (B = -0.32, SE = 0.07, p < 0.001 and B = -0.56, SE = 0.08, p < 0.001, respectively). Social support was protective against discrimination (pregnancy interaction B = -0.23, SE = 0.09, p = 0.011; postpartum interaction B = -0.35, SE = 0.07, p < 0.001). There was no interaction between discrimination and resilience at either time.

LIMITATIONS

The study relied on self-reported measures and only included pregnant people who received group prenatal care in two urban regions, limiting generalizability.

CONCLUSIONS

Social support and resilience may protect against perinatal depressive symptoms. Social support may also buffer the adverse effects of discrimination on perinatal depressive symptoms, particularly during the postpartum period.

A multilevel developmental psychopathology model of childbirth and the perinatal transition

Despite recent applications of a developmental psychopathology perspective to the perinatal period, these conceptualizations have largely ignored the role that childbirth plays in the perinatal transition. Thus, we present a conceptual model of childbirth as a bridge between prenatal and postnatal health. We argue that biopsychosocial factors during pregnancy influence postnatal health trajectories both directly and indirectly through childbirth experiences, and we focus our review on those indirect effects. In order to frame our model within a developmental psychopathology lens, we first describe "typical" biopsychosocial aspects of pregnancy and childbirth. Then, we explore ways in which these processes may deviate from the norm to result in adverse or traumatic childbirth experiences. We briefly describe early postnatal health trajectories that may follow from these birth experiences, including those which are adaptive despite traumatic childbirth, and we conclude with implications for research and clinical practice. We intend for our model to illuminate the importance of including childbirth in multilevel perinatal research. This advancement is critical for reducing perinatal health disparities and promoting health and well-being among birthing parents and their children.

Perceived discrimination and quality of life for African American and Caucasian American cancer patients: a coping mediation analysis of subtle and overt microaggressions

OBJECTIVE

Perceived discrimination (PD; e.g. racism, agism, sexism, etc.) negatively impacts quality of life (QOL) among cancer patients. Prior research has established that for African American Cancer Patients (AACPs) only disengagement/denial coping mediated the PD-QOL relationship. In contrast, for Caucasian American Cancer Patients (CACPs), both agentic and disengagement/denial coping were mediators of the PD-QOL relationship. However, according to social constraint theory there may be a difference between subtle and overt PD in terms of the utility of certain coping mechanisms in relation to QOL, especially for AACPs.

METHOD

217 AACPs and 121 CACPs completed measures of PD, coping (agentic, disengagement/denial, adaptive disengagement) and QOL. PD items were classified as subtle or overt microaggressions. PD was mainly attributed to race/ethnicity by AACPs and to income, age, and physical appearance for CACPs.

RESULTS

: In both subtle and overt microaggression models with CACPs, agentic coping and disengagement/denial coping were significant mediators of PD-QOL. Like CACPs, for AACPs, agentic and disengagement/denial coping were significant in the context of subtle microaggressions. In contrast, for overt microaggression only disengagement/denial coping was a significant mediator of the PD-QOL relationship for AACPs. Adaptive disengagement was related to QOL only for AACPs.

CONCLUSIONS

: Whereas more research is needed, it appears that overt microaggressions for AACPs, that consist mainly of racial and ethnic maltreatment, constitute a class of social contexts that may raise above the threshold for serious threat and harm, and, as a result, disengagement/constraint may reduce negative consequences. This additional burden for AACPs contributes to disparities in QOL. Future research is needed on the utility of adaptive disengagement for AACPs in relation to PD.

The Potential for Using a Shortened Version of the Everyday Discrimination Scale in Population Research with Young Adults: A Construct Validation Investigation

Discrimination is associated with numerous psychological health outcomes over the life course. The nine-item Everyday Discrimination Scale (EDS) is one of the most widely used measures of discrimination; however, this nine-item measure may not be feasible in large-scale population health surveys where a shortened discrimination measure would be advantageous. The current study examined the construct validity of a combined two-item discrimination measure adapted from the EDS by Add Health (N = 14,839) as compared to the full nine-item EDS and a two-item EDS scale (parallel to the adapted combined measure) used in the National Survey of American Life (NSAL; N = 1,111) and National Latino and Asian American Study (NLAAS) studies (N = 1,055). Results identified convergence among the EDS scales, with high item-total correlations, convergent validity, and criterion validity for psychological outcomes, thus providing evidence for the construct validity of the two-item combined scale. Taken together, the findings provide support for using this reduced scale in studies where the full EDS scale is not available.

Discrimination and Cardiovascular Health in Black Americans: Exploring Inflammation as a Mechanism and Perceived Control as a Protective Factor

OBJECTIVE

Inflammation may be an integral physiological mechanism through which discrimination impacts cardiovascular health and contributes to racial health disparities. Limited research has examined psychosocial factors that protect against the negative effects of discrimination on inflammation. Perceived control is a promising possible protective factor, given that it has been shown to moderate the relationship between other psychosocial stressors and physiological outcomes. This study thus tested whether systemic inflammation mediated the link between discrimination and cardiovascular health and whether perceived control moderated this relationship.

METHODS

Data for this project included 347 non-Hispanic/Latinx Black adults (mean [standard deviation] age = 51.64 [11.24] years; 33% female) taken from the Midlife in the United States study. Perceived control and daily discrimination were assessed via self-report, and inflammation was measured via circulating levels of C-reactive protein (CRP), interleukin-6 (IL-6), fibrinogen, and tumor necrosis factor α. Cardiovascular health was measured by morbidity of cardiovascular conditions: heart disease, hypertension, and/or stroke.

RESULTS

CRP (indirect effect: b = 0.004, 95% confidence interval [CI] = 0.001-0.007) and fibrinogen (indirect effect: b = 0.002, 95% CI = 0.0003-0.005) mediated the link between discrimination and cardiovascular conditions. Perceived control moderated the relationship between discrimination and CRP ( F (1, 293) = 4.58, Δ R2 = 0.013, b = -0.02, SE = 0.01, p = .033). CRP mediated the link between discrimination and cardiovascular conditions only for those who reported low levels of perceived control (Index = -0.003, 95% CI = -0.007 to -0.0001).

CONCLUSION

Findings provide empirical evidence of inflammation as a mechanism linking discrimination to cardiovascular conditions among Black Americans. Additionally, perceived control may be protective. Findings could suggest beliefs about control as a potential intervention target to help reduce the negative effects of discrimination on cardiovascular health among Black Americans.

Linked emergence of racial disparities in mental health and epigenetic biological aging across childhood and adolescence

Marginalization due to structural racism may confer an increased risk for aging-related diseases - in part - via effects on people's mental health. Here we leverage a prospective birth cohort study to examine whether the emergence of racial disparities in mental health and DNA-methylation measures of biological aging (i.e., DunedinPACE, GrimAge Acceleration, PhenoAge Acceleration) are linked across childhood and adolescence. We further consider to what extent racial disparities are statistically accounted for by perinatal and postnatal factors in preregistered analyses of N=4,898 participants from the Future of Families & Child Wellbeing Study, of which N=2,039 had repeated saliva DNA methylation at ages 9 and 15 years. We find that racially marginalized children had higher levels of externalizing and internalizing behaviors and diverging longitudinal internalizing slopes. Black compared to White identifying children, children living in more racially segregated neighborhoods, and racially marginalized children more affected by colorism tended to have higher age-9 levels of biological aging and more biological age acceleration over adolescence. Notably, longitudinal increases in internalizing and externalizing behavior were correlated with longitudinal increases in biological aging. While racial and ethnic disparities in mental health were largely statistically accounted for by socioeconomic variables, racial differences in biological aging were often still visible beyond covariate controls. Our findings indicate that racial disparities in mental health and biological aging are linked and emerge early in life. Programs promoting racial health equity must address the psychological and physical impacts of structural racism in children. Comprehensive measures of racism are lacking in current population cohorts.

Necessary, burdensome, or threatening? Awareness of Black-White disparities in health care access and self-rated health for Black and White Americans

Awareness of racial health care inequities is one prerequisite to eliminating them. Although extant research has described awareness of racial health care inequities in the United States, the health impacts of such awareness on communities that are most impacted by these inequities remains unknown. Therefore, we examined associations between awareness of Black-White racial health care inequities and self-rated health for Black and White adults in the United States. We used survey data from non-Hispanic Black and White participants (N = 6,449) who responded to the national American Health Values Survey (2015-2016) to test associations between awareness of Black-White inequities in health care and self-rated health. Accurate awareness of health care inequities was associated with 47% higher odds of poorer self-rated health for Black individuals. Inaccurate awareness was associated with 36% higher odds of poorer self-rated health for White individuals. Accurate awareness may be adaptive, yet place an additional burden on Black individuals. Inaccurate awareness may harm White individuals' health. Health care system changes and alleviation of racism-related stress may be preventive supports for the health of Black individuals. Accurate awareness should be a goal for White individuals, not only to prevent health risks, but to also facilitate structural change for racial equity.

Utilizing epigenetics to study the shared nature of development and biological aging across the lifespan

Recently, biological aging has been quantified in DNA-methylation samples of older adults and applied as so-called "methylation profile scores" (MPSs) in separate target samples, including samples of children. This nascent research indicates that (1) biological aging can be quantified early in the life course, decades before the onset of aging-related disease, (2) is affected by common environmental predictors of childhood development, and (3) shows overlap with "developmental processes" (e.g., puberty). Because the MPSs were computed using algorithms developed in adults, these studies indicate a molecular link between childhood environments, development, and adult biological aging. Yet, if MPSs can be used to connect development and aging, previous research has only traveled one way, deriving MPSs developed in adults and applying them to samples of children. Researchers have not yet quantified epigenetic measures that reflect the pace of child development, and tested whether resulting MPSs are associated with physical and psychological aging. In this perspective I posit that combining measures of biological aging with new quantifications of child development has the power to address fundamental questions about life span: How are development and experience in childhood related to biological aging in adulthood? And what is aging?

Active Inference and Social Actors: Towards a Neuro-Bio-Social Theory of Brains and Bodies in Their Worlds

Although research including biological concepts and variables has gained more prominence in sociology, progress assimilating the organ of experience, the brain, has been theoretically and technically challenging. Formal uptake and assimilation have thus been slow. Within psychology and neuroscience, the traditional brain, which has made brief appearances in sociological research, is a "bottom-up" processor in which sensory signals are passed up the neural hierarchy where they are eventually cognitively and emotionally processed, after which actions and responses are generated. In this paper, we introduce the Active Inference Framework (AIF), which casts the brain as a Bayesian "inference engine" that tests its "top-down" predictive models against "bottom-up" sensory error streams in its attempts to resolve uncertainty and make the world more predictable. After assembling and presenting key concepts in the AIF, we describe an integrated neuro-bio-social model that prioritizes the microsociological assertion that the scene of action is the situation, wherein brains enculturate. Through such social dynamics, enculturated brains share models of the world with one another, enabling collective realities that disclose the actions afforded in those times and places. We conclude by discussing this neuro-bio-social model within the context of exemplar sociological research areas, including the sociology of stress and health, the sociology of emotions, and cognitive cultural sociology, all areas where the brain has received some degree of recognition and incorporation. In each case, sociological insights that do not fit naturally with the traditional brain model emerge intuitively from the predictive AIF model, further underscoring the interconnections and interdependencies between these areas, while also providing a foundation for a probabilistic sociology.

Black Americans suppress emotions when prejudice is believed to stem from shared ignorance

Past research examining lay theories of the origins of prejudice has focused on white Americans and has not considered how Black Americans' lay theories of prejudice may impact emotion regulation following discrimination. Across three samples of Black Americans (N = 419), the present research examined relationships between endorsement of two lay theories of prejudice origins (1, beliefs that prejudice stems from shared social ignorance and 2, that prejudice stems from malice). Stronger beliefs that prejudice stems from shared ignorance were associated with greater expression suppression following experiences of racial discrimination (studies 1b and 2), which was, in turn, associated with psychological distress (study 2). By centering the beliefs and experiences of Black Americans in response to discrimination events, the present research has implications for understanding how emotion regulation following racial discrimination is impacted by marginalized groups' conceptualizations of prejudice. Future research should investigate how these factors impact health disparities.

The Effects of the Flint water crisis on the educational outcomes of school-age children

In 2014, the municipal water source in Flint, Michigan was switched, causing lead from aging pipes to leach into the city's drinking water. While lead exposure in Flint children increased modestly on average, some children were exposed to high lead levels. Surveys of Flint residents show the water crisis was also associated with increased levels of stress, anxiety, and depression. We use Michigan's administrative education data and utilize synthetic control methods to examine the impact of the crisis on Flint's school-age children. We find decreases in math achievement and increases in special needs classification, even among children living in homes with copper (rather than lead) water service lines. Low socioeconomic status students and younger students experienced the largest effects on math achievement, and boys experienced the largest effects on special needs classification. Our results point toward the broad negative effects of the crisis on children and suggest that existing estimates may substantially underestimate the overall societal cost of the crisis.

Health Care Stereotype Threat and Sexual and Gender Minority Well-Being

Sexual and gender minorities (SGMs) have experienced progressive change over the last 50 years. However, this group still reports worse health and health care experiences. An innovative survey instrument that applies stereotype threat to the health care setting, health care stereotype threat (HCST), offers a new avenue to examine these disparities. We harmonized two national probability data sets of SGMs-Generations and TransPop-capturing 503 gay men, 297 lesbians, 467 bisexuals, and 221 trans people. Using these data, we, first, explored how HCST's association with self-rated health and psychological distress changed while considering more established constructs: discrimination and stigma. Second, we examined how HCST's association varied across SGM groups. Results suggest that HCST is a unique predictor net of the associations with discrimination and stigma. Furthermore, results highlight the more consequential associations for trans people on well-being compared to gay men. We discuss implications of these findings for future research and potential interventions.

A biobehavioural and social-structural model of inflammation and executive function in pediatric chronic health conditions

Evidence indicates that pediatric chronic health conditions (CHCs) often impair executive functioning (EF) and impaired EF undermines pediatric CHC management. This bidirectional relationship likely occurs due to biobehavioural and social-structural factors that serve to maintain this feedback loop. Specifically, biobehavioural research suggests that inflammation may sustain a feedback loop that links together increased CHC severity, challenges with EF, and lower engagement in health promoting behaviours. Experiencing social and environmental inequity also maintains pressure on this feedback loop as experiencing inequities is associated with greater inflammation, increased CHC severity, as well as challenges with EF and engagement in health promoting behaviours. Amidst this growing body of research, a model of biobehavioural and social-structural factors that centres inflammation and EF is warranted to better identify individual and structural targets to ameliorate the effects of CHCs on children, families, and society at large. This paper proposes this model, reviews relevant literature, and delineates actionable research and clinical implications.

How Education Shapes Indigenous Health Inequalities in the USA and Mexico

Indigenous peoples around the world face significant health disparities relative to the dominant groups in their countries, yet the magnitude and patterns of health disparities vary across countries. We use data from the National Health Interview Survey and Mexican Family Life Survey to examine the health of Indigenous peoples in Mexico and American Indians and Alaska Natives in the USA and to evaluate how they fare relative to the majority populations in their countries (non-Indigenous Mexicans and non-Hispanic Whites, respectively). We assess disparities in self-rated health and activity limitations, with a focus on how Indigenous health disparities intersect with educational gradients in health. Regression analyses reveal three primary findings. First, Indigenous health disparities are larger in the USA than in Mexico. Second, differences in educational attainment account for most of the differences between Indigenous and non-Indigenous populations in Mexico, but less than half in the USA. Third, in both countries, health is moderated by educational attainment such that between-group disparities are largest at the highest levels of education. However, for Indigenous Mexicans there is a "cross-over" in which Indigenous Mexicans report better health at the lowest level of education. Overall, this study finds a weak relationship between education and Indigenous health, and raises the question about the validity of using traditional measures of SES in Indigenous contexts.

Experiences of racial discrimination and adverse gene expression among black individuals in a level 1 trauma center sample

Up to 40 % of individuals who sustain traumatic injuries are at risk for posttraumatic stress disorder (PTSD) and the conditional risk for developing PTSD is even higher for Black individuals. Exposure to racial discrimination, including at both interpersonal and structural levels, helps explain this health inequity. Yet, the relationship between racial discrimination and biological processes in the context of traumatic injury has yet to be fully explored. The current study examined whether racial discrimination is associated with a cumulative measure of biological stress, the gene expression profile conserved transcriptional response to adversity (CTRA), in Black trauma survivors. Two-weeks (T1) and six-months (T2) post-injury, Black participants (N = 94) provided a blood specimen and completed assessments of lifetime racial discrimination and PTSD symptoms. Mixed effect linear models evaluated the relationship between change in CTRA gene expression and racial discrimination while adjusting for age, gender, body mass index (BMI), smoking history, heavy alcohol use history, and trauma-related variables (mechanism of injury, lifetime trauma). Results revealed that for individuals exposed to higher levels of lifetime racial discrimination, CTRA significantly increased between T1 and T2. Conversely, CTRA did not increase significantly over time in individuals exposed to lower levels of lifetime racial discrimination. Thus, racial discrimination appeared to lead to a more sensitized biological profile which was further amplified by the effects of a recent traumatic injury. These findings replicate and extend previous research elucidating the processes by which racial discrimination targets biological systems.

Social Support Buffers the Effects of Prenatal Depressed Mood: A Mixed-Methods Study

BACKGROUND: Women use various coping strategies to deal with stress and depression. These strategies are shaped by social contexts over the life course and may attenuate and/or exacerbate the physiologic effects of depression. AIMS: The purpose of this study was to determine whether coping strategies (active, disengaged, or social support coping) moderate depression-related diurnal cortisol dysregulation and to explore how social context influences women's use of coping. METHODS: This was a mixed-methods study of pregnant women (N = 65) during mid-pregnancy. Cortisol was measured in saliva collected during the waking hours of the day. Participants completed the Edinburgh Depression Scale and the Brief COPE. A subset of the sample participated in semistructured qualitative interviews (n = 20). RESULTS: Social support coping, but not active or disengaged coping, moderated end-of-day cortisol levels. Among depressed women, higher use of social support was associated with lower and more dynamic (i.e., less flat) diurnal cortisol rhythms. The qualitative findings revealed how complex social dynamics related to financial insecurity, lack of mutuality, and social identity affected women's use of and access to social support. CONCLUSION: These findings support theories of the stress-buffering effects of social support. Future research is needed to examine how social determinants affect access to social support, and how early life social experiences condition women's adaptive formation of social support coping strategies over the life course. Clinically, these findings underscore the value of relationship-centered nursing care for depressed women.

Patterns and Life Course Determinants of Black-White Disparities in Biological Age Acceleration: A Decomposition Analysis

Despite the prominence of the weathering hypothesis as a mechanism underlying racialized inequities in morbidity and mortality, the life course social and economic determinants of Black-White disparities in biological aging remain inadequately understood. This study uses data from the Health and Retirement Study (n = 6,782), multivariable regression, and Kitagawa-Blinder-Oaxaca decomposition to assess Black-White disparities across three measures of biological aging: PhenoAge, Klemera-Doubal biological age, and homeostatic dysregulation. It also examines the contributions of racial differences in life course socioeconomic and stress exposures and vulnerability to those exposures to Black-White disparities in biological aging. Across the outcomes, Black individuals exhibited accelerated biological aging relative to White individuals. Decomposition analyses showed that racial differences in life course socioeconomic exposures accounted for roughly 27% to 55% of the racial disparities across the biological aging measures, and racial disparities in psychosocial stress exposure explained 7% to 11%. We found less evidence that heterogeneity in the associations between social exposures and biological aging by race contributed substantially to Black-White disparities in biological aging. Our findings offer new evidence of the role of life course social exposures in generating disparities in biological aging, with implications for understanding age patterns of morbidity and mortality risks.

Cognitive-Affective-Behavioral Pathways Linking Adversity and Discrimination to Daily Pain in African-American Adults

The tendency to ruminate, magnify, and experience helplessness in the face of pain - known as pain catastrophizing - is a strong predictor of pain outcomes and is associated with adversity. The ability to maintain functioning despite adversity - referred to as resilience - also influences pain outcomes. Understanding the extent to which pain catastrophizing and resilience influence relations between adversity and daily pain in healthy African-American adults could improve pain risk assessment and mitigate racial disparities in the transition from acute to chronic pain. This study included 160 African-American adults (98 women). Outcome measures included daily pain intensity (sensory, affective) and pain impact on daily function (pain interference). Adversity measures included childhood trauma exposure, family adversity, chronic burden from recent stressors, and ongoing perceived stress. A measure of lifetime racial discrimination was also included. Composite scores were created to capture early-life adversity (childhood trauma, family adversity) versus recent-life adversity (perceived stress, chronic burden). Increased pain catastrophizing was correlated with increased adversity (early and recent), racial discrimination, pain intensity, and pain interference. Decreased pain resilience was correlated with increased recent-life adversity (not early-life adversity or racial discrimination) and correlated with increased pain intensity (not pain-related interference). Bootstrapped multiple mediation models revealed that relationships between all adversity/discrimination and pain outcomes were mediated by pain catastrophizing. Pain resilience, however, was not a significant mediator in these models. These findings highlight opportunities for early interventions to reduce cognitive-affective-behavioral risk factors for persisting daily pain among African-American adults with greater adversity exposure by targeting pain catastrophizing.

Discrimination during childbirth and postpartum care utilization among Black birthing people in California, United States

BACKGROUND

The purpose of this study was to investigate the relationship between discrimination during childbirth hospitalization and postpartum care utilization among Black birthing people in California, United States.

METHODS

This was a secondary analysis of data from the Listening to Mothers in California survey, a population-based survey of individuals with a singleton hospital-based birth in California in 2016. The primary outcome was number of postpartum care visits. The primary exposures were racial, language, and insurance discrimination. A multiple linear regression model was used to estimate associations between discrimination and postpartum care use, adjusting for sociodemographic covariates.

RESULTS

Black birthing people in the sample had an average of two postpartum visits. Almost 15% of the sample reported one or more forms of discrimination during hospital-based childbirth. In adjusted models, racial discrimination (β = 0.09, 95% CI = 0.04-0.14, p < 0.01) and language discrimination (β = 1.03, 95% CI = 0.98-1.07, p < 0.01) were associated with increased postpartum visits, while insurance discrimination was linked to decreased postpartum visits (β = -0.96, 95% CI = -1.04 to -0.89, p < 0.01).

CONCLUSION

Among Black birthing people in California, the drivers of postpartum care utilization after childbirth are complex. There are multiple negative drivers (e.g., experiencing racial and language discrimination and unmet needs), barriers (e.g., insurance discrimination), and positive drivers (e.g., clinician type and education) that affect postpartum care utilization among Black birthing people.

Racial and Ethnic Disparities in Delivery In-Hospital Mortality or Maternal End-Organ Injury: A Multistate Analysis, 2007-2020

Background: In the United States, Black maternal mortality is 2-4 × higher than that of White maternal mortality, with differences also present in severe maternal morbidity and other measures. However, limited research has comprehensively studied multilevel social determinants of health, and their confounding and effect modification on obstetrical outcomes. Materials and Methods: We performed a retrospective multistate analysis of adult inpatient delivery hospitalizations (Florida, Kentucky, Maryland, New Jersey, New York, North Carolina, and Washington) between 2007 and 2020. Multilevel multivariable models were used to test the confounder-adjusted association for race/ethnicity and the binary outcomes (1) in-hospital mortality or maternal end-organ injury and (2) in-hospital mortality only. Stratified analyses were performed to test effect modification. Results: The confounder-adjusted odds ratio showed that Black (1.33, 95% confidence interval [CI]: 1.30-1.36) and Hispanic (1.14, 95% CI: 1.11-1.18) as compared with White patients were more likely to die in-hospital or experience maternal end-organ injury. For Black and Hispanic patients, stratified analysis showed that findings remained significant in almost all homogeneous strata. After statistical adjustment, Black as compared with White patients were more likely to die in-hospital (1.49, 95% CI: 1.21-1.82). Conclusions: Black and Hispanic patients had higher adjusted odds of in-patient mortality and end-organ damage after birth than White patients. Race and ethnicity serve as strong predictors of health care inequality, and differences in outcomes may reflect broader structural racism and individual implicit bias. Proposed solutions require immense and multifaceted active efforts to restructure how obstetrical care is provided on the societal, hospital, and patient level.

Short-term cortisol adaption to discrimination and Mexican-origin adolescents' mental and sleep health

Discrimination experiences are a salient contributor to the health disparities facing Latina/x/o youth. The biopsychosocial model of minority health posits that discrimination influences health through wear and tear on the biological stress responses, including the hypothalamic-pituitary-adrenal (HPA) axis, which is a primary stress response system in the body. Emerging evidence suggests that discrimination alters the secretion of cortisol, the end product of the HPA axis, yet, whether the daily processes between discrimination and diurnal cortisol response influence mental and sleep health remains unanswered. This study integrated daily diary and post-diary survey data to examine whether daily diurnal cortisol responses to discrimination influence adolescents' mental (depressive symptoms, anxiety) and sleep (sleep quality, duration) health in a sample of Mexican-origin youth (N = 282; M age = 17.10; 55% female). Results showed that adolescents who experienced more discrimination across the four-day diary period exhibited steeper diurnal cortisol slopes and lower evening cortisol; however, such physiological responses tended to be associated with poorer adolescents' mental and sleep health. The current study underscores the potential adaptation cost associated with short-term cortisol adaptation in the face of discrimination.

Clinical Framework for Dismantling Antiblack Racism in the Clinic Room

Children who identify as Black or multiracial report significantly higher exposure to adverse childhood experiences, which places them at greater risk for poor mental and physical health outcomes. These disparities and increasing awareness of racism as an adverse childhood experience has resulted in the American Academy of Pediatrics, American Psychological Association, and other groups declaring racism a public health crisis. To provide high-quality care, providers who engage with patients and families impacted by systemic racism must be aware of its role in health disparities. This requires clinicians to have the knowledge and skills to discuss racism with colleagues, patients, and families. To promote clinicians' competence to engage in these discussions, this article 1) sensitizes providers to historical and contextual factors that inform experiences with anti-Black racism and health disparities and 2) offers strategies to address anti-Black racism in clinical care.Embracing the process of brave, informed conversations about race represents a pathway for building trust between providers and patients, a key component of various health outcomes. Additionally, these foundational skills of reflection, cultural humility, and bias recognition will be needed to engage in allyship and advocacy both within and beyond the exam room.

The impact of perceived everyday discrimination and income on racial and ethnic disparities in PTSD, depression, and anxiety among veterans

OBJECTIVES

Black and Hispanic/Latinx individuals experience a greater burden of mental health symptoms as compared to White individuals in the general population. Examination of ethnoracial disparities and mechanisms explaining these disparities among veterans is still in its nascence. The current study examined perceived everyday discrimination and income as parallel mediators of the association between race/ethnicity and PTSD, depression, and general anxiety symptoms in a sample of White, Black, and Hispanic/Latinx veterans stratified by gender.

METHODS

A random sample of 3,060 veterans living across the U.S. (oversampled for veterans living in high crime communities) completed a mail-based survey. Veterans completed self-report measures of perceived discrimination via the Everyday Discrimination Scale, PTSD symptoms via the Posttraumatic Stress Disorder Checklist-5, depressive symptoms via the Patient Health Questionnaire, and anxiety symptoms via the Generalized Anxiety Disorder Questionnaire.

RESULTS

Models comparing Black vs. White veterans found that the significant effect of race on PTSD, depression, and anxiety symptoms was mediated by both perceived discrimination and income for both male and female veterans. Results were less consistent in models comparing Hispanic/Latinx vs. White veterans. Income, but not perceived discrimination, mediated the relationship between ethnicity/race and depression and anxiety symptoms, but only among women.

CONCLUSIONS

Results suggest that discrimination and socioeconomic status are important mechanisms through which marginalized social status negatively impacts mental health.

The social patterning of vicarious discrimination: Implications for health equity

BACKGROUND

Most research on discrimination and health operationalizes discrimination as direct individual experiences. Here, we examine the social patterning of vicarious discrimination, an important but largely overlooked dimension of discrimination.

METHODS

Drawing on community-based participatory research with a multi-stage probability sample (n = 178) of African Americans in Tallahassee, Florida, we measured vicarious discrimination, or exposure to discrimination through one's family and friends. We used chi-square tests to examine gender differences in the social domains and relational sources of vicarious discrimination. Negative binomial regression models were fit to identify predictors of exposure to vicarious discrimination.

RESULTS

Vicarious discrimination is more prevalent than direct experiences of discrimination (73 versus 61%) and more than 20% of participants report vicarious discrimination in the absence of direct discrimination. For women, vicarious discrimination most often involved the workplace; for men, police. However, gender differences are smaller for vicarious versus direct discrimination. Close friends and children were top relational sources of vicarious discrimination for men and women, respectively. Middle-aged participants reported the most vicarious discrimination.

CONCLUSIONS

Overall, our data show that vicarious discrimination is more common than widely understood and associated with individual-level sociodemographic characteristics that index one's position in broader social systems. The prevalence of vicarious discrimination in the absence of direct discrimination suggests that standard approaches, which measure individual exposures in isolation, are subject to misclassification bias. Our results imply that existing research on discrimination and health, which already demonstrates substantial harm, underestimates African Americans' true exposures to salient aspects of discrimination.

Black-White differences in perceived lifetime discrimination by education and income in the MIDUS Study in the U.S

There is growing evidence on the negative effects of perceived discrimination on health outcomes and their interactions with indicators of socioeconomic status. However, less has been studied on whether income and education lead individuals of a different race to encounter different discriminatory experiences in their lifetime. Using data from the national survey of the Midlife Development in the United States-MIDUS 1 (1995-1996) and MIDUS Refresher (2011-2014)-on eight measures of perceived lifetime discrimination, this study compares discriminatory experiences of Black and White persons in two time periods. We applied generalized structural equation models and generalized linear models to test multiplicative effects of income and education by race on lifetime discrimination. In both periods, we find substantive disparities between White and Black people in all types of lifetime discrimination, with Black people reporting much higher levels of discrimination. Such disparities exacerbated in the top cohorts of society, yet these associations have changed in time, with White individuals reporting increasing levels of discrimination. Results show that, for Black people in the mid-1990s, perceived discrimination increased as education and income increased. This finding persisted for education by the early 2010s; income effects changed as now both, low- and high-income Black people, reported the highest levels of discrimination. These findings highlight a policy conundrum, given that increasing income and education represent a desirable course of action to improve overall discrimination and health outcomes. Yet, we show that they may unintendingly exacerbate racial disparities in discrimination. We also show that the U.S. is moving toward a stagnation period in health outcomes improvement, with racial disparities in discrimination shrinking at the expense of a deterioration of whites' lifetime discriminatory experiences. Our results highlight the need for a multi-systems policy approach to prevent all forms of discrimination including those due to historical, institutional, legal, and sociopolitical structures.

Incident racial discrimination predicts elevated C-Reactive protein in the Black Women's experiences Living with Lupus (BeWELL) study

INTRODUCTION

Racial discrimination is a distinct health threat that increases disease risk among Black Americans. Psychosocial stress may compromise health through inflammatory mechanisms. This study examines incident experiences of racial discrimination and changes in the inflammatory biomarker C-reactive protein (CRP) over a two-year period among Black women with systemic lupus erythematosus (SLE)-an inflammatory autoimmune disease sensitive to psychosocial stress and characterized by stark racial inequities in outcomes.

METHODS

Data are from the Black Women's Experiences Living with Lupus (BeWELL) Study. Participants (n = 380) from metropolitan Atlanta, Georgia were enrolled from April 2015 to May 2017. Incident racial discrimination was assessed bi-annually via self-report using the Experiences of Discrimination measure. CRP was assessed annually over a two-year period. Latent change score analyses modeled longitudinal within-person associations between incident racial discrimination and change in log-transformed CRP from baseline to Year 2.

RESULTS

Incident experiences of racial discrimination were associated with elevated log-CRP across the two-year study period (b = 0.039, SE = 0.017, 95% CI: 0.006, 0.071). For each domain of incident racial discrimination experienced, CRP increased 3.98%.

CONCLUSION

This study contributes to growing evidence on the biological consequences of racism and is the first to document an association between incident racial discrimination and changes in inflammation among Black women with SLE. Racial inequities in SLE outcomes and other diseases driven by inflammatory pathways may be explained in part through experiences of racial discrimination.

Institutional Racism and Health: a Framework for Conceptualization, Measurement, and Analysis

Despite growing interest in the health-related consequences of racially discriminatory institutional policies and practices, public health scholars have yet to reach a consensus on how to measure and analyze exposure to institutional racism. The purpose of this paper is to provide an overview of the conceptualization, measurement, and analysis of institutional racism in the context of quantitative research on minority health and health disparities in the United States. We begin by providing definitions of key concepts (e.g., racialization, racism, racial inequity) and describing linkages between these ideas. Next, we discuss the hypothesized mechanisms that link exposure to institutional racism with health. We then provide a framework to advance empirical research on institutional racism and health, informed by a literature review that summarizes measures and analytic approaches used in previous studies. The framework addresses six considerations: (1) policy identification, (2) population of interest, (3) exposure measurement, (4) outcome measurement, (5) study design, and (6) analytic approach. Research utilizing the proposed framework will help inform structural interventions to promote minority health and reduce racial and ethnic health disparities.

Racial-Ethnic Disparities in Dual-Function Life Expectancy

BACKGROUND

This study develops a new concept, dual functionality, that integrates physical and cognitive function. We use the concept to define a measure of dual-function life expectancy (2FLE) and assess racial-ethnic inequalities in aging.

METHODS

Drawing on data from the National Health Interview Survey Linked Mortality Files and the Health and Retirement Study, we define dual functionality as having no limitations in activities of daily living and being free of dementia. We use this measure and Sullivan life tables to estimate age-50 total life expectancy and age-50 2FLE for women and men across 4 racial-ethnic and nativity groups.

RESULTS

At ages 50-54, between 79.0% (95% CI: 73.5, 84.5) and 87.6% (95% CI: 84.0, 91.2) of (non-Hispanic) Black, foreign-born Hispanic, and U.S.-born Hispanic women and men remain dual functional as compared with 90.4% (95% CI: 89.3, 91.4) and 91.4% (95% CI: 90.2, 92.5) of (non-Hispanic) White women and men, respectively. These and corresponding racial-ethnic disparities in dual functionality through ages 85 and older translate into substantial inequalities in 2FLE. For instance, the Black-White gap in age-50 2FLE is 6.9 years (95% CI: -7.5, -6.4) for women and 6.0 years (95% CI: -6.6, -5.4) for men.

CONCLUSIONS

Black, foreign-born Hispanic, and U.S.-born Hispanic older adults are estimated to live a smaller percentage of their remaining years with dual functionality than White older adults. These results reveal stark racial-ethnic inequalities in aging that have significant implications for quality of life, caregiving, and health needs.

Everyday perceptions of safety and racial disparities in hair cortisol concentration

OBJECTIVE

Black-White disparities in physiological stress during adolescence are increasingly evident but remain incompletely understood. We examine the role of real-time perceptions of safety in the context of everyday routines to gain insight into the sources of observed adolescent racial differences in chronic stress as measured by hair cortisol concentration (HCC).

METHOD

We combined social survey, ecological momentary assessment (EMA), and hair cortisol data on 690 Black and White youth ages 11-17 from wave 1 of the Adolescent Health and Development in Context (AHDC) study to investigate racial differences in physiological stress. Individual-level, reliability-adjusted measures of perceived unsafety outside the home were drawn from a week-long smartphone-based EMA and tested for association with hair cortisol concentration.

RESULTS

We observed a statistically significant interaction (p < .05) between race and perceptions of unsafety. For Black youth, perceived unsafety was associated with higher HCC (p < .05). We observed no evidence of an association between perceptions of safety and expected HCC for White youth. For youth who perceive their out-of-home activity locations to be consistently safe, the racial difference in expected HCC was not statistically significant. At the high end of perceived unsafety, however, Black-White differences in HCC were pronounced (0.75 standard deviations at the 95th percentile on perceived unsafety; p < .001).

DISCUSSION

These findings call attention to the role of everyday perceptions of safety across non-home routine activity contexts in explaining race differences in chronic stress as assessed by hair cortisol concentrations. Future research may benefit from data on in situ experiences to capture disparities in psychological and physiological stress.

Perceived racial discrimination and polysubstance use among racial/ethnic minority adolescents in the United States

OBJECTIVE

Polysubstance use among adolescents is a significant public health concern, yet most studies on adolescent substance use focus on a singular substance. This study is one of the first to investigate the association between perceived racial discrimination (PRD) in school and polysubstance use among racial/ethnic minority adolescents using a nationally representative sample.

METHODS

Data was from the 2021 Adolescent Behaviors and Experiences Survey. The sample included 4145 racial/ethnic minority adolescents (52.8% female). Hierarchical binary logistic regression was used to examine the association between PRD in school and polysubstance use among racial/ethnic minority adolescents.

RESULTS

About 12% of racial/ethnic minority adolescents engaged in polysubstance use and 23.4% reported experiencing PRD in school sometimes/most of the time/always. Controlling for other factors, experiencing PRD in school sometimes/most of the time/always was associated with 1.52 times higher odds of polysubstance use when compared to adolescents who never experienced PRD in school (OR=1.52, p=.044, 95% CI=1.01-2.30). Cyberbullying victimization, symptoms of depression, and being emotionally abused by a parent during COVID-19 were also associated with polysubstance use.

CONCLUSION

Controlling for demographic characteristics and psychosocial stressors, PRD in school was significantly associated with higher odds of polysubstance use among racial/ethnic minority adolescents. The findings of this study could inform clinicians and policymakers of the association between PRD in school and polysubstance use, which could contribute to early identification of polysubstance use among racial/ethnic minority adolescents.

Social Isolation: An Unequally Distributed Health Hazard

Social isolation is a potent predictor of poor health, mortality, and dementia risk. A great deal of research across national contexts provides causal evidence for these linkages and identifies key explanatory mechanisms through which isolation affects health. Research on social isolation recognizes that some people are more likely than others to be isolated, but over the past several decades, researchers have focused primarily on the consequences of isolation for health rather than a systematic assessment of the social conditions that foster isolation over the life course. In this article, we review the available evidence on inequities in social isolation and develop a conceptual framework to guide future research on structural systems that fuel social isolation over the life course. Future work in this area has the potential to identify root causes of inequality in social isolation, as well as targeted policy levers to reduce isolation in vulnerable populations.

Attributions for Everyday Discrimination and All-Cause Mortality Risk Among Older Black Women: A Latent Class Analysis Approach

BACKGROUND AND OBJECTIVES

This study examined the relationship between number of attributed reasons for everyday discrimination and all-cause mortality risk, developed latent classes of discrimination attribution, and assessed whether these latent classes were related to all-cause mortality risk among U.S. older Black women.

RESEARCH DESIGN AND METHOD

Participants were from the 2006 and 2008 waves of the Health and Retirement Study (N = 1,133; 335 deaths). Vital status was collected through the National Death Index through 2013 and key informant reports through 2019. Latent class analyses were conducted on discrimination attributions. Weighted Cox proportional hazards model was used to predict all-cause mortality. Analyses controlled for demographic characteristics, socioeconomic status, and health.

RESULTS

Reporting greater attributions for everyday discrimination was associated with higher mortality risk (hazard ratio [HR] = 1.117; 95% confidence interval [CI]: 1.038-1.202; p < .01), controlling for demographic characteristics, socioeconomic status, and health as well as health behaviors. A 4-class solution of the latent class analysis specified the following attribution classes: No/Low Attribution; Ancestry/Gender/Race/Age; Age/Physical Disability; High on All Attributions. When compared to the No/Low Attribution class, membership in the High on All Attributions class was associated with greater mortality risk (HR = 2.809; CI: 1.458-5.412; p < .01).

DISCUSSION AND IMPLICATIONS

Findings underscore the importance of everyday discrimination experiences from multiple sources in shaping all-cause mortality risk among older Black women. Accordingly, this study problematizes the homogenization of Black women in aging research and suggests the need for health interventions that consider Black women's multiplicity of social statuses.

Lifetime vicarious experiences of major discrimination and depressive symptoms among middle-aged and older black adults

OBJECTIVES

Racial disparities in later-life depression among Americans are well-documented. Perceived discrimination has been linked to depressive symptoms among aging Black adults, but little research has considered how vicarious exposure to discrimination shapes the mental health of middle-aged and older Black adults.

METHODS

A subsample of Black adults aged 50-69 years (N = 273) were drawn from the Nashville Stress and Health Study. Lifetime vicarious exposures to major discrimination were assessed. Additionally, multivariate linear regression was employed to examine the association between vicarious experiences of major discrimination and depressive symptoms.

RESULTS

Once the Black adults in the sample had reached ages 50 and older, the most common discriminatory events that they had vicariously experienced in their lifetime occurred as a result of their loved ones' unfair interactions with law enforcement and the job market, respectively. Furthermore, our findings revealed that vicarious experiences of major discrimination were associated with higher levels of depressive symptoms among middle-aged and older Black adults.

CONCLUSION

Vicarious, as well as personal, exposures to discrimination shape the mental health of Black Americans over the lifespan. The secondhand effects of discrimination must be considered for interventions aimed at reducing the mental health consequences of racism-related adversity as Black adults age.

Racialized Health Inequities: Quantifying Socioeconomic and Stress Pathways Using Moderated Mediation

Racism drives population health inequities by shaping the unequal distribution of key social determinants of health, such as socioeconomic resources and exposure to stressors. Research on interrelationships among race, socioeconomic resources, stressors, and health has proceeded along two lines that have largely remained separate: one examining differential effects of socioeconomic resources and stressors on health across racialized groups (moderation processes), and the other examining the role of socioeconomic resources and stressors in contributing to racial inequities in health (mediation processes). We conceptually and analytically integrate these areas using race theory and a novel moderated mediation approach to path analysis to formally quantify the extent to which an array of socioeconomic resources and stressors-collectively and individually-mediate racialized health inequities among a sample of older adults from the Health and Retirement Study. Our results yield theoretical contributions by showing how the socioeconomic status-health gradient and stress processes are racialized (24% of associations examined varied by race), substantive contributions by quantifying the extent of moderated mediation of racial inequities (approximately 70%) and the relative importance of various social factors, and methodological contributions by showing how commonly used simple mediation approaches that ignore racialized moderation processes overestimate-by between 5% and 30%-the collective roles of socioeconomic status and stressors in accounting for racial inequities in health.

The Mediating Role of Systemic Inflammation and Moderating Role of Race/Ethnicity in Racialized Disparities in Incident Dementia: A Decomposition Analysis

Background

Exposure to systemic racism is linked to increased dementia burden. To assess systemic inflammation as a potential pathway linking exposure to racism and dementia disparities, we investigated the mediating role of C-reactive protein (CRP), a systemic inflammation marker, and the moderating role of race/ethnicity on racialized disparities in incident dementia.

Methods

In the US Health and Retirement Study (n=5,143), serum CRP was measured at baseline (2006, 2008 waves). Incident dementia was classified by cognitive tests over a six-year follow-up. Self-reported racialized categories were a proxy for exposure to the racialization process. We decomposed racialized disparities in dementia incidence (non-Hispanic Black and/or Hispanic vs. non-Hispanic White) into 1) the mediated effect of CRP, 2) the moderated portion attributable to the interaction between racialized group membership and CRP, and 3) the controlled direct effect (other pathways through which racism operates).

Results

The 6-year cumulative incidence of dementia was 15.5%. Among minoritized participants (i.e., non-Hispanic Black and/or Hispanic), high CRP levels (> 75th percentile or 4.57mcg/mL) was associated with 1.27 (95%CI: 1.01,1.59) times greater risk of incident dementia than low CRP (<4.57mcg/mL). Decomposition analysis comparing minoritized versus non-Hispanic White participants showed that the mediating effect of CRP accounted for 2% (95% CI: 0%, 6%) of the racial disparity, while the interaction effect between minoritized group status and high CRP accounted for 12% (95% CI: 2%, 22%) of the disparity. Findings were robust to potential violations of causal mediation assumptions.

Conclusions

Systemic inflammation mediates racialized disparities in incident dementia.

The Mediating Role of Systemic Inflammation and Moderating Role of Race/Ethnicity in Racialized Disparities in Incident Dementia: A Decomposition Analysis

Background

Exposure to systemic racism is linked to increased dementia burden. To assess systemic inflammation as a potential pathway linking exposure to racism and dementia disparities, we investigated the mediating role of C-reactive protein (CRP), a systemic inflammation marker, and the moderating role of race/ethnicity on racialized disparities in incident dementia.

Methods

In the US Health and Retirement Study (n=5,143), serum CRP was measured at baseline (2006, 2008 waves). Incident dementia was classified by cognitive tests over a six-year follow-up. Self-reported racialized categories were a proxy for exposure to the racialization process. We decomposed racialized disparities in dementia incidence (non-Hispanic Black and/or Hispanic vs. non-Hispanic White) into 1) the mediated effect of CRP, 2) the moderated portion attributable to the interaction between racialized group membership and CRP, and 3) the controlled direct effect (other pathways through which racism operates).

Results

The 6-year cumulative incidence of dementia was 15.5%. Among minoritized participants (i.e., non-Hispanic Black and/or Hispanic), high CRP levels (> 75th percentile or 4.57μg/mL) was associated with 1.27 (95%CI: 1.01,1.59) times greater risk of incident dementia than low CRP (≤4.57μg/mL). Decomposition analysis comparing minoritized versus non-Hispanic White participants showed that the mediating effect of CRP accounted for 2% (95% CI: 0%, 6%) of the racial disparity, while the interaction effect between minoritized group status and high CRP accounted for 12% (95% CI: 2%, 22%) of the disparity. Findings were robust to potential violations of causal mediation assumptions.

Conclusions

Systemic inflammation mediates racialized disparities in incident dementia.

Socially Stratified Epigenetic Profiles Are Associated With Cognitive Functioning in Children and Adolescents

Children's cognitive functioning and educational performance are socially stratified. Social inequality, including classism and racism, may operate partly via epigenetic mechanisms that modulate neurocognitive development. Following preregistered analyses of data from 1,183 participants, ages 8 to 19 years, from the Texas Twin Project, we found that children growing up in more socioeconomically disadvantaged families and neighborhoods and children from marginalized racial/ethnic groups exhibit DNA methylation profiles that, in previous studies of adults, were indicative of higher chronic inflammation, lower cognitive functioning, and a faster pace of biological aging. Furthermore, children's salivary DNA methylation profiles were associated with their performance on in-laboratory tests of cognitive and academic skills, including processing speed, general executive function, perceptual reasoning, verbal comprehension, reading, and math. Given that the DNA methylation measures that we examined were originally developed in adults, our results suggest that children show molecular signatures that reflect the early life social determinants of lifelong disparities in health and cognition.
