ABSTRACT

Importance: Racial discrimination is a psychosocial stressor associated with youths' risk for psychiatric symptoms. Scarce data exist on the moderating role of amygdalar activation patterns among Black youths in the US. Objective: To investigate the association between racial discrimination and risk for psychopathology moderated by neuroaffective processing. Design, Setting, and Participants: This cohort study used longitudinal self-report and functional magnetic resonance imaging (fMRI) data from Black youth participants in the US from the Adolescent Brain Cognitive Development (ABCD) study. Data were analyzed from January 2023 to May 2024. Exposures: At time 1 of the current study (12 months after baseline), youths self-reported on their experiences of interpersonal racial discrimination and their feelings of marginalization. Amygdalar response was measured during an emotionally valenced task that included blocks of faces expressing either neutral or negative emotion. Main Outcomes and Measures: At 24 and 36 months after baseline, youths reported their internalizing (anxiety and depressive symptoms) and externalizing symptoms (aggression and rule-breaking symptoms). Results: A total of 1596 youths were a mean (SD) age of 10.92 (0.63) years, and 803 were female (50.3%). Families in the study had a mean annual income range of $25 000 to $34 999. Two factors were derived from factor analysis: interpersonal racial discrimination and feelings of marginalization (FoM). Using structural equation modeling in a linear regression, standardized ß coefficients were obtained. Neural response to faces expressing negative emotion within the right amygdala significantly moderated the association between FoM and changes in internalizing symptoms (ß = -0.20; 95% CI, -0.32 to -0.07; P < .001). The response to negative facial emotion within the right amygdala significantly moderated the association between FoM and changes in externalizing symptoms (ß = 0.24; 95% CI, 0.04 to 0.43; P = .02). Left amygdala response to negative emotion significantly moderated the association between FoM and changes in externalizing symptoms (ß = -0.16; 95% CI, -0.32 to -0.01; P = .04). Conclusions and Relevance: In this cohort study of Black adolescents in the US, findings suggest that amygdala function in response to emotional stimuli can both protect and intensify the affective outcomes of feeling marginalized on risk for psychopathology, informing preventive interventions aimed at reducing the adverse effects of racism on internalizing and externalizing symptoms among Black youths.

ABSTRACT

Importance: Racial discrimination increases the risk of adverse brain health outcomes, potentially via neuroplastic changes in emotion processing networks. The involvement of deep brain regions (brainstem and midbrain) in these responses is unknown. Potential associations of racial discrimination with alterations in deep brain functional connectivity and accelerated epigenetic aging, a process that substantially increases vulnerability to health problems, are also unknown. Objective: To examine associations of racial discrimination with brainstem and midbrain resting-state functional connectivity (RSFC) and DNA methylation age acceleration (DMAA) among Black women in the US. Design, Setting, and Participants: This cohort study was conducted between January 1, 2012, and February 28, 2015, and included a community-based sample of Black women (aged ≥18 years) recruited as part of the Grady Trauma Project. Self-reported racial discrimination was examined in association with seed-to-voxel brain connectivity, including the locus coeruleus (LC), periaqueductal gray (PAG), and superior colliculus (SC); an index of DMAA (Horvath clock) was also evaluated. Posttraumatic stress disorder (PTSD), trauma exposure, and age were used as covariates in statistical models to isolate racial discrimination-related variance. Data analysis was conducted between January 10 and October 30, 2023. Exposure: Varying levels of racial discrimination exposure, other trauma exposure, and posttraumatic stress disorder (PTSD). Main Outcomes and Measures: Racial discrimination frequency was assessed with the Experiences of Discrimination Scale, other trauma exposure was evaluated with the Traumatic Events Inventory, and current PTSD was evaluated with the PTSD Symptom Scale. Seed-to-voxel functional connectivity analyses were conducted with LC, PAG, and SC seeds. To assess DMAA, the Methylation EPIC BeadChip assay (Illumina) was conducted with whole-blood samples from a subset of 49 participants. Results: This study included 90 Black women, with a mean (SD) age of 38.5 (11.3) years. Greater racial discrimination was associated with greater left LC RSFC to the bilateral precuneus (a region within the default mode network implicated in rumination and reliving of past events; cluster size k = 228; t85 = 4.78; P < .001, false discovery rate-corrected). Significant indirect effects were observed for the left LC-precuneus RSFC on the association between racial discrimination and DMAA (ß [SE] = 0.45 [0.16]; 95% CI, 0.12-0.77). Conclusions and Relevance: In this study, more frequent racial discrimination was associated with proportionately greater RSFC of the LC to the precuneus, and these connectivity alterations were associated with DMAA. These findings suggest that racial discrimination contributes to accelerated biological aging via altered connectivity between the LC and default mode network, increasing vulnerability for brain health problems.

ABSTRACT

Centuries of systemic racism in the United States have led to Black Americans facing a disproportionate amount of life stressors. These stressors can have negative effects on mental and physical health, contributing to inequities throughout the lifespan. The current study used longitudinal data from 692 Black adults in the rural South to examine the ways in which neighborhood stress, financial strain, and interpersonal experiences of racial discrimination operate independently and in tandem to impact depressive symptoms and sleep problems over time. Findings provided strong support for univariate and additive stress effects and modest support for multiplicative stress effects. Results underscore how multiple stressors stemming from systemic racism can undermine health among Black Americans and highlight the need for further research on factors that promote well-being in the face of these stressors.

ABSTRACT

BACKGROUND: Race-related stress (RRS) is an unrecognized source of moral injury (MI)-or the emotional and/or spiritual suffering that may emerge after exposure to events that violate deeply held beliefs. Additionally, MI has not been explored as a mechanism of risk for post-traumatic stress disorder (PTSD) in trauma-exposed civilians. We examined relations among exposure to potentially morally injurious events (moral injury exposure, MIE), related distress (moral injury distress, MID), and RRS in Black Americans. Potential indirect associations between RRS and PTSD symptoms via MID were also examined. METHODS: Black Americans (n = 228; 90.4% female; Mage = 31.6 years. SDage = 12.8 years) recruited from an ongoing study of trauma completed measures assessing civilian MIE and MID, RRS, and PTSD. Bivariate correlations were conducted with MIE and MID, and mediation analysis with MID, to examine the role of MI in the relationship between RRS and PTSD symptom severity. RESULTS: MIE was significantly correlated with cultural (r = 0.27), individual (r = 0.29), and institutional (r = 0.25) RRS; MID also correlated with cultural (r = 0.31), individual (r = 0.31), and institutional (r = 0.26) RRS (ps < 0.001). We found an indirect effect of RRS on PTSD symptoms via MID (ß = 0.10, p < 0.005). CONCLUSIONS: All types of RRS were associated with facets of MI, which mediated the relationship between RRS and current PTSD symptoms. MI may be a potential mechanism through which RRS increases the risk for PTSD in Black individuals.

ABSTRACT

Racism-related stressors, from experiences of both implicit and explicit racial discrimination to systemic socioeconomic disadvantage, have a cumulative impact on Black Americans' health. The present narrative review synthesizes peripheral (neuroendocrine and inflammation markers), psychophysiological (heart-rate variability, skin conductance), and neuroimaging (structural and functional) findings that demonstrate unique associations with racism-related stress. Emerging evidence reveals how racism-related stressors contribute to differential physiological and neural responses and may have distinct impacts on regions involved with threat and social processing. Ultimately, the neurophysiological effects of racism-related stress may confer biological susceptibility to stress and trauma-related disorders. We note critical gaps in the literature on the neurophysiological impact of racism-related stress and outline additional research that is needed on the multifactorial interactions between racism and mental health. A clearer understanding of the interactions between racism-related stress, neurophysiology, and stress- and trauma-related disorders is critical for preventative efforts, biomarker discovery, and selection of effective clinical treatments for Black Americans.

ABSTRACT

OBJECTIVES: Black older adults have a higher vascular burden compared to non-Hispanic White (NHW) older adults, which may put them at risk for a form of depression known as vascular depression (VaDep). The literature examining VaDep in Black older adults is sparse. The current study addressed this important gap by examining whether vascular burden was associated with depressive symptoms in Black older adults. METHODS: Participants included 113 Black older adults from the Healthy Brain Project, a substudy of the Health, Aging, and Body Composition Study. In multiple regression analyses, clinical vascular burden (sum of vascular conditions) and white matter hyperintensity (WMH) volume predicted depressive symptoms as measured by the Center for Epidemiologic Studies Depression Scale, controlling for demographic variables. Follow-up analyses compared the associations in the Black subsample and in 179 NHW older adults. RESULTS: Higher total WMH volume, but not clinically-defined vascular burden, predicted higher concurrent depressive symptoms and higher average depressive symptoms over 4 years. Similar associations were found between uncinate fasciculus (UF) WMHs and concurrent depressive symptoms and between superior longitudinal fasciculus WMHs and average depressive symptoms. The association between depressive symptoms and UF WMH was stronger in Black compared to NHW individuals. CONCLUSION: This research is consistent with the VaDep hypothesis and extends it to Black older adults, a group that has historically been underrepresented in the literature. Results highlight WMH in the UF as particularly relevant to depressive symptoms in Black older adults and suggest this group may be particularly vulnerable to the negative effects of WMH.

ABSTRACT

Prior research has shown that racial discrimination (RD) impacts activation in threat network regions, including the ventromedial prefrontal cortex (vmPFC) and middle occipital cortex during attention to threat-relevant stimuli. However, little is known about the biological mechanisms that may modulate these effects; inflammation may be a pathway linking RD and threat network activation. As such, the current study aimed to explore whether systemic inflammation, measured by C-reactive protein (CRP) levels, may moderate the relationship between RD and activation in the vmPFC and middle occipital cortex during attention to threat. Blood samples for inflammatory marker (CRP) assays were obtained from forty Black American women (mean [SD] age, 39.93 [9.97] years; range, 22-58 years) recruited from an ongoing trauma study; participants also viewed threat-relevant stimuli as part of an attention task during fMRI. We found that CRP moderated the relationship between RD and vmPFC activation during attention to threat, such that participants with relatively higher concentrations of CRP ( ≥ 23.97 mg/L) demonstrated significant positive associations between RD and vmPFC activation [ß = 0.18, CI (0.04, 0.32), t = 2.65, p = 0.01]. No significant associations were observed for participants who showed moderate (10.89 mg/L) or low (0.20 mg/L) CRP concentrations. CRP did not moderate the relationship between RD and middle occipital cortex activation. Our data present a mechanism through which RD may influence immune system activation and, in turn, threat network activation. Inflammation may contribute to brain health vulnerabilities in Black Americans via its effects on threat circuits; this merits further investigation in large-scale studies.

ABSTRACT

Although offspring of women exposed to childhood trauma exhibit elevated rates of psychopathology, many children demonstrate resilience to these intergenerational impacts. Among the variety of factors that likely contribute to resilience, epigenetic processes have been suggested to play an important role. The current study used a prospective design to test the novel hypothesis that offspring epigenetic aging - a measure of methylation differences that are associated with infant health outcomes - moderates the relationship between maternal exposure to childhood adversity and offspring symptomatology. Maternal childhood adversity was self-reported during pregnancy via the ACEs survey and the CTQ, which assessed total childhood trauma as well as maltreatment subtypes (i.e., emotional, physical, and sexual abuse). Offspring blood samples were collected at or shortly after birth and assayed on a DNA methylation microarray, and offspring symptomatology was assessed with the CBCL/1.5-5 when offspring were 2-4 years old. Results indicated that maternal childhood trauma, particularly sexual abuse, was predictive of offspring symptoms (ps = 0.003-0.03). However, the associations between maternal sexual abuse and offspring symptomatology were significantly attenuated in offspring with accelerated epigenetic aging. These findings further our understanding of how epigenetic processes may contribute to and attenuate the intergenerational link between stress and psychopathology.

ABSTRACT

This article serves as an introduction to the special section in the Journal of Traumatic Stress related to the 38th annual meeting of the International Society for Traumatic Stress Studies, held in Atlanta, Georgia (USA) in November 2022. The theme of this meeting, "Trauma as a Transdiagnostic Risk Factor Across the Lifespan," provided an opportunity to recognize the far-reaching impact of trauma and how traumatic experiences can become embedded into the mind, body, and societal spirit. This introductory article outlines the importance of harnessing multiple perspectives to address these wide-ranging sequelae of trauma and provides an overview of the series of contributions to the special section.

ABSTRACT

This study examines whether shift-and-persist coping, a coping strategy defined by accepting challenges and remaining hopeful for the future, is associated with psychosocial and physical health and/or moderates the effects of contextual stress (i.e., racial discrimination, financial strain) on health among African American adolescents living in the rural Southeastern United States. Participants (N = 299, 56% boys, Mage = 12.91) completed measures of shift-and-persist coping, contextual stress, and psychosocial and physical health. Shift-and-persist coping was generally associated with better health but did not buffer the effects of contextual stress. Results suggest that shift-and-persist coping may serve as a source of resilience among African American adolescents living in a context where many experience heightened contextual stress.

ABSTRACT

OBJECTIVE: Racism is a multifaceted system of oppression that disproportionately harms Black mothers and children across the lifespan. Despite reliable evidence that racism is associated with worse mental health outcomes (eg, increased depressive symptoms), less is known about potential intergenerational effects of Black mothers' experiences of racism on children's mental health, as well as how traumatic experiences influence these pathways. In this cross-sectional quantitative study, we aimed (1) to replicate the finding that maternal experiences of racism are associated with both maternal and child depression; (2) to identify whether maternal experiences of racism are indirectly associated with child depression via the effect of maternal depression; and (3) to test whether the indirect effect of racism on child depression via maternal depression is conditioned on maternal trauma. METHOD: Black mothers and their children (N = 148 dyads) were recruited from an urban hospital and were interviewed about their experiences of racism, trauma, and mental health symptoms. The mothers' average age was 35.16 years (SD = 8.75) and the children's average age was 10.03 years (SD = 1.51). RESULTS: First, we found that maternal experiences of racism were associated with more severe maternal depression (r = 0.37, p < .01) as well as more severe child depression (r = 0.19, p = .02). Second, we found that maternal experiences of racism were indirectly associated with child depression through the effect of maternal depression (ab = 0.76, 95% CI = 0.26, 1.37). Third, we found that maternal trauma exposure moderated this indirect effect such that, at relatively lower levels of maternal trauma exposure, the indirect effect of maternal experiences of racism on child depression was nonsignificant (ωlow = -0.05, 95% CI = -0.50, 0.45), whereas at relatively higher levels of maternal trauma exposure, the indirect effect of maternal experiences of racism on child depression was statistically significant (ωhigh= .65, 95% CI = 0.21, 1.15). CONCLUSION: These findings suggest that the indirect effect of maternal experiences of racism on child depression through the effect of maternal depression depends on the degree of maternal trauma exposure. This study advances the literature by shedding light on key processes that can explain the intergenerational effects of racism as well as contextual factors that can exacerbate racism's downstream consequences across generations.

ABSTRACT

The COVID-19 pandemic resulted in substantial hardship for Black Americans, leading to increased stress and mental health difficulties. We used longitudinal data from the Protecting Strong African American Families (ProSAAF) intervention study to test the hypothesis that improved couple functioning following ProSAAF participation would serve as a constructed resilience resource during the pandemic, buffering the impact of elevated pandemic-related stressors on change in depressive symptoms. We found that COVID-19-related stress predicted change in depressive symptoms from prepandemic to during the pandemic, that ProSAAF predicted improved couple functioning, and that positive change in couple functioning buffered the impact of pandemic stressors on change in depressive symptoms. These effects resulted in a significant indirect buffering effect of ProSAAF on the association between COVID-19-related stress and change in depressive symptoms through its effects on change in couple functioning. The results suggest that relationship intervention may increase resilience to unanticipated community-wide stress and promote mental health.

ABSTRACT

BACKGROUND: Racial discrimination is consistently associated with adverse health outcomes and has been linked to structural decrements in brain white matter. However, it is unclear whether discrimination-related neuroplastic changes could indirectly affect health outcomes. Our goal was to evaluate indirect associations of racial discrimination on health outcomes through white matter microstructure in a sample of trauma-exposed Black women. METHODS: A trauma study in an urban hospital setting recruited 79 Black women who received a history and physical examination to assess medical disorders (compiled into a summed total of disorder types). Participants reported on experiences of racial discrimination and underwent diffusion tensor imaging; fractional anisotropy values were extracted from white matter pathways previously linked to racial discrimination (corpus callosum, including the body and genu; anterior cingulum bundle; and superior longitudinal fasciculus) and entered into mediational models. RESULTS: Indirect effects of racial discrimination on medical disorders through left anterior cingulum bundle fractional anisotropy were significant (ß = 0.07, SE = 0.04, 95% CI [0.003, 0.14]) after accounting for trauma and economic disadvantage. Indirect effects of racial discrimination on medical disorders through corpus callosum genu fractional anisotropy were also significant (ß = 0.08, SE = 0.04, 95% CI [0.01, 0.16]). CONCLUSIONS: Racial discrimination may increase risk for medical disorders via neuroplastic effects on microstructural integrity of stress-sensitive prefrontal white matter tracts. Racial discrimination-related changes in these tracts may affect health behaviors, which, in turn, influence vulnerability for medical disorders. These data highlight the connections between racial discrimination, prefrontal white matter connections, and incidence of medical disorders in Black Americans.

ABSTRACT

INTRODUCTION: Posttraumatic stress disorder (PTSD) and depression are common in service members and veterans, and the response to currently available treatments is often modest at best. Recent studies suggest potential benefit with psychedelic-assisted therapies (PATs), particularly 3,4-methylenedioxymethamphetamine-assisted therapy for PTSD and psilocybin-assisted therapy for depression. This study examined beliefs and perceived barriers regarding PAT among service members and veterans to inform the delivery of these treatments if they are approved by the FDA. MATERIALS AND METHODS: Twenty-one service members and veterans (67% male, 81% White, and 43% active duty) with a history of traumatic brain injury and co-occurring cognitive and psychological symptoms completed a measure assessing baseline knowledge and views of PAT, read a brief psychoeducation regarding PAT, and then responded to questions related to their beliefs and perceived barriers to PAT. RESULTS: Before psychoeducation, participants reported a neutral view of psychedelic drugs (M = 2.76; range: 1-5), PAT (M = 3.33), and interest in PAT (M = 3.10). After psychoeducation, participants reported a significantly more positive view of psychedelic drugs (M = 3.24, P = .014) and interest in PAT (M = 3.67, P = .016). Overall, participants indicated that they would support PAT availability in medical settings if proven beneficial (M = 4.52; 5 = "agree strongly") and they would support a loved one engaging in PAT (M = 4.29). The most frequently reported health concerns were concern of long-term effects (43%), fear of losing their mind (33%), fear of personality changes (33%), and fear of traumatic brain injury complications (24%). The most frequently endorsed barriers were time commitment, transportation, financial concerns, work, and childcare (33%-19%), with 48% reporting no barriers. CONCLUSIONS: This is the first study to explore beliefs and perceived barriers regarding PAT among service members and veterans. These results indicate that military populations may be interested in PAT, particularly if psychoeducation and outreach regarding these treatments occurred. If FDA approved, it will be important to facilitate command support and address logistical barriers to ensure appropriate access within military contexts.

ABSTRACT

Experiences of racial discrimination are common among Black youth and predict worse mental health cross-sectionally and over time. Additional research is needed to address lingering questions regarding the direction of effect(s) underlying these patterns, differences in the magnitude of effects across adolescence, and gender differences. To address these gaps, the current study tested bidirectional linkages between racial discrimination and depressive symptoms at the between- (interpersonal) and within- (intrapersonal) level using 4 waves of data from 889 Black youth (54% female) from Georgia and Iowa. Participants reported experiences of racial discrimination and depressive symptoms at ages 10.6 years (Wave 1), 12.5 years (Wave 2), 15.7 years (Wave 3), and 18.8 years (Wave 4). The cross-lagged panel model (CLPM) was used to examine between-person associations over time, and the random intercept cross-lagged panel model (RI-CLPM) was used to examine within-person associations over time. Results were consistent across models, revealing significant concurrent associations between racial discrimination and depressive symptoms, significant lagged effects from racial discrimination to depressive symptoms, and no significant lagged effects from depressive symptoms to racial discrimination. Effects did not differ across adolescence, and there were few gender differences in the degree of association between racial discrimination and depressive symptoms. Findings provide rigorous evidence that experiencing greater racial discrimination is associated with increases in depressive symptoms throughout adolescence and add to a growing body of work showing that racial discrimination can undermine mental health and well-being among Black youth.

ABSTRACT

The current study examined concurrent and longitudinal associations between experiences of racial discrimination and private regard (i.e., feelings about being Black and other Black people) among 346 Black early adolescents who completed four assessments over two years. Between-person (interpersonal) and within-person (intrapersonal) effects were tested to provide a rigorous and comprehensive examination of these associations. There was minimal evidence of significant between-person effects in which youth experiencing varying levels of racial discrimination differed in their private regard. However, at the within-person level, there were significant negative concurrent associations between racial discrimination and private regard, indicating that youths' positive racial identity was undermined at times when they were encountering higher levels of racial discrimination than they typically did. Results highlight significant intrapersonal links between racial discrimination and private regard and underscore the continued need for interventions to eliminate racial discrimination and to support Black youth experiencing it.

ABSTRACT

In a sample of 685 late middle-aged Black adults (M age at 2019 = 57.17 years), we examined the effects of loneliness and per capita income on accelerated aging using a newly developed DNA-methylation based index: the DunedinPACE. First, using linear, mixed effects regression in a growth curve framework, we found that change in DunedinPACE was dependent on age, with a linear model best fitting the data (b = 0.004, p < 0.001), indicating that average pace of change increased among older participants. A quadratic effect was also tested, but was non-significant. Beyond the effect of age, both change in loneliness (b = 0.009, p < 0.05) and change in per capita income (b = -0.016, p < 0.001) were significantly associated with change in DunedinPACE across an 11-year period, accounting for significant between person variability observed in the unconditional model. Including non-self-report indices of smoking and alcohol use did not reduce the association of loneliness or per capita income with DunedinPACE. However, change in smoking was strongly associated with change in DunedinPACE such that those reducing their smoking aged less rapidly than those continuing to smoke. In addition, both loneliness and per capita income were associated with DunedinPACE after controlling for variation in cell-types.

ABSTRACT

Racial discrimination (RD) has been consistently linked to adverse brain health outcomes. These may be due in part to RD effects on neural networks involved with threat appraisal and regulation; RD has been linked to altered activity in the rostral anterior cingulate cortex (rACC) and structural decrements in the anterior cingulum bundle and hippocampus. In the present study, we examined associations of RD with cingulate, hippocampus and amygdala gray matter morphology in a sample of trauma-exposed Black women. Eighty-one Black women aged 19-62 years were recruited as part of an ongoing study of trauma. Participants completed assessments of RD, trauma exposure, and posttraumatic stress disorder (PTSD), and underwent T1-weighted anatomical imaging. Cortical thickness, surface area and gray matter volume were extracted from subregions of cingulate cortex, and gray matter volume was extracted from amygdala and hippocampus, and entered into partial correlation analyses that included RD and other socio-environmental variables. After correction for multiple comparisons and accounting for variance associated with other stressors and socio-environmental factors, participants with more RD exposure showed proportionally lower cortical thickness in the left rACC, caudal ACC, and posterior cingulate cortex (ps < = 0.01). These findings suggest that greater experiences of RD are linked to compromised cingulate gray matter thickness. In the context of earlier findings indicating that RD produces increased response in threat neurocircuitry, our data suggest that RD may increase vulnerability for brain health problems via cingulate cortex alterations. Further research is needed to elucidate biological mechanisms for these changes.

ABSTRACT

OBJECTIVE: The association between childhood adversity and adulthood health is well established, but few studies have examined potential effects of childhood adversity on partner health in couples. This study examined the long-term health impact of childhood adversity on individuals as well as their significant others. METHOD: The participants were 163 distinguishable dyads from the Family and Community Health Study. Health outcomes included both self-reported chronic illness and a messenger RNA index of accelerated aging. The actor-partner interdependence model with structural equation methods was used to test the hypothesis. RESULTS: Replicating prior research, childhood adversity was associated with more chronic illness and an accelerated speed of aging. Further, participants' health in adulthood was affected by both own and partner experiences of childhood adversity. There were no gender differences. CONCLUSION: Our findings replicate and extend prior research on the long-term impact of exposure to childhood adversity, suggesting that adverse childhood experiences are also harmful to romantic partners. Further studies are required to examine potential mechanisms. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
