RESUMEN

OBJECTIVE: To estimate the effect of geographic variation in historic slavery on perinatal outcomes [chronic hypertension, hypertensive disorders of pregnancy (HDP), very preterm birth (VPTB), or very low birth weight birth (VLBW)] among Black people living in states where slavery was legal in 1860 and test mediation by Black homeownership. METHODS: We linked data from the 1860 census (the proportion of enslaved residents) to natality data on outcomes (2013-2021) using resident county. The percent of Black residents in a county who owned their home was a potential mediator. We fit log binomial models to estimate risk ratios (RRs) representing total and controlled direct effects (accounting for Black homeownership) of proportion enslaved on outcomes, accounting for potential confounding using marginal structural models. RESULTS: Among 2,443,198 included births, 8.8% (213,829) experienced HDP, 4.1% (100,549) chronic hypertension, 3.3% (81,072) VPTB, and 2.6% (62,538) VLBW. There was an increase in chronic hypertension and VPTB risk, but not HDP or VLBW, in counties with a 10% greater proportion enslaved in 1860 [adjusted RR: 1.06, 95% CI: (1.02, 1.1); 1.02 (1.00, 1.05); 1.00 (0.98, 1.02); 1.01 (1.00, 1.03)]. There was not evidence of mediation by Black homeownership. CONCLUSIONS: Historic slavery remains relevant for perinatal health.

RESUMEN

Considerable racial/ethnic disparities persist in exposure to life stressors and socioeconomic resources that can directly affect threat neurocircuitry, particularly the amygdala, that partially mediates susceptibility to adverse posttraumatic outcomes. Limited work to date, however, has investigated potential racial/ethnic variability in amygdala reactivity or connectivity that may in turn be related to outcomes such as post-traumatic stress disorder (PTSD). Participants from the AURORA study (n = 283), a multisite longitudinal study of trauma outcomes, completed functional magnetic resonance imaging and psychophysiology within approximately two-weeks of trauma exposure. Seed-based amygdala connectivity and amygdala reactivity during passive viewing of fearful and neutral faces were assessed during fMRI. Physiological activity was assessed during Pavlovian threat conditioning. Participants also reported the severity of posttraumatic symptoms 3 and 6 months after trauma. Black individuals showed lower baseline skin conductance levels and startle compared to White individuals, but no differences were observed in physiological reactions to threat. Further, Hispanic and Black participants showed greater amygdala connectivity to regions including the dorsolateral prefrontal cortex (PFC), dorsal anterior cingulate cortex, insula, and cerebellum compared to White participants. No differences were observed in amygdala reactivity to threat. Amygdala connectivity was associated with 3-month PTSD symptoms, but the associations differed by racial/ethnic group and were partly driven by group differences in structural inequities. The present findings suggest variability in tonic neurophysiological arousal in the early aftermath of trauma between racial/ethnic groups, driven by structural inequality, impacts neural processes that mediate susceptibility to later PTSD symptoms.

RESUMEN

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.

RESUMEN

From its inception, development and psychopathology theorists have sought to uncover the earliest forms of risk for mental health challenges in children, to prevent the development of more severe, intractable manifestations of psychopathology. Large familial risk registries have advanced our understanding of early, potentially modifiable factors that could prevent or mitigate the expression of challenging symptoms of neurodevelopmental conditions, and similar registries have been proposed to advance understanding of ADHD and related phenotypes. Data from single-site studies, largely focused on perinatal exposure to maternal mood disorders, reveal that a robust predictor of child psychopathology is parental psychopathology. However, early developmental trajectories of psychopathology risk may be better captured using transdiagnostic approaches in pregnancy, capturing the full range of mental health symptoms. We describe here the need for a parental mental health registry that begins prenatally that includes deep behavioral phenotyping across a range of transdiagnostic indicators of mental health risk to prevent psychopathology in children. This registry has the potential to uncover pathways to psychopathology risk in childhood and support the discovery of novel mechanisms to be targeted for prevention and intervention.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Experiencing racism is linked to lower subjective social status (SSS), defined as one's perception of their position in society. SSS is influenced by power, prestige, and objective socioeconomic status (SES). Previous findings suggest that race-related stress may be related to adverse mental health outcomes through SSS in Black Americans, a population that has been deeply affected by continuing legacies of oppression. The current study examines the indirect association between race-related stress and posttraumatic stress disorder (PTSD) and depression symptoms through SSS in a community sample of largely trauma-exposed Black Americans (N = 173). Hierarchical regression analyses indicated that overall race-related stress significantly predicted lower SSS, higher PTSD symptoms, and higher depression symptoms. Analyses also revealed indirect effects of cultural race-related stress on PTSD and depression symptoms through SSS after controlling for SES. Results suggest that the experience of race-related stress, particularly cultural race-related stress, which involves the degradation and disparagement of one's culture and worldview, is associated with more severe PTSD and depression symptoms potentially due to these experiences decreasing Black Americans' SSS. Findings support the need for systemic intervention strategies to disrupt the cultural oppression of Black Americans and improve the societal value and mental health of this population.

RESUMEN

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.

RESUMEN

We expand upon prior work (Gibbons et al., ) relating childhood stressor effects, particularly harsh childhood environments, to risky behavior and ultimately physical health by adding longer-term outcomes - deoxyribonucleic acid (DNA) methylation-based measures of accelerated aging (DNAm-aging). Further, following work on the effects of early exposure to danger (McLaughlin et al., ), we also identify an additional pathway from harsh childhood environments to DNAm-aging that we label the danger/FKBP5 pathway, which includes early exposure to dangerous community conditions that are thought to impact glucocorticoid regulation and pro-inflammatory mechanisms. Because different DNAm-aging indices provide different windows on accelerated aging, we contrast effects on early indices of DNAm-aging based on chronological age with later indices that focused on predicting biological outcomes. We utilize data from Family and Community Health Study participants (N = 449) from age 10 to 29. We find that harshness influences parenting, which, in turn, influences accelerated DNAm-aging through the risky cognitions and substance use (i.e., behavioral) pathway outlined by Gibbons et al. (). Harshness is also associated with increased exposure to threat/danger, which, in turn, leads to accelerated DNAm-aging through effects on FKBP5 activity and enhanced pro-inflammatory tendencies (i.e., the danger/FKBP5 pathway).

RESUMEN

OBJECTIVE: Race-related lifetime stress exposure (LSE) including racial discrimination, trauma, and stressful life events have been shown to contribute to racial health disparities. However, little is known about associations between race-related stressors and premature biological aging that confer the risk of adverse health outcomes. Even less is known about the mechanisms through which race-related stressors may be associated with accelerated aging. Early evidence suggests psychological processes such as anger, and particularly the internalization of anger, may play a role. METHODS: In a community sample of predominantly low-income Black adults (n = 219; age = 45.91 [12.33] years; 64% female), the present study examined the association of race-related LSE (as defined by exposure to racial discrimination, trauma, and stressful life events) and epigenetic age acceleration through anger expression. RESULTS: Internalized and externalized anger expression were each significantly associated with LSE and age acceleration. Although LSE was not directly associated with age acceleration (ΔR2 = 0.001, p = .64), we found that greater LSE was indirectly associated with age acceleration through increases in internalized, but not externalized, anger (indirect effect: ß = 0.03, standard error = 0.02, 95% confidence interval = 0.003 to 0.08; total effect: ß = 0.02, 95% confidence interval = -0.25 to 0.31). CONCLUSIONS: These results suggest race-related LSE may elicit the internalization of anger, which, along with the externalization of anger, may initiate detrimental epigenetic alterations that confer the risk of adverse health outcomes. These findings lay the groundwork for longitudinal studies of the association between race-related stress and racial health disparities.

RESUMEN

OBJECTIVE: Sickle cell disease (SCD) is a group of inherited blood disorders. The central feature of this chronic condition is pain. Several identified risk factors exacerbate the impact of pain on quality of life (QOL) in SCD; however, there are relatively fewer investigations of strengths-based resilience variables that might buffer the influence of pain on living with SCD. The purpose of this study was to examine strength-based resilience processes in youth with SCD and their parents. Grounded in an ecological resilience-risk model, we evaluated whether adolescent and parent protective factors (pain acceptance, mindfulness, and psychological flexibility) moderated the relation between adolescent-reported pain burden and QOL. METHODS: Ninety-three 12- to 18-year-old adolescents with SCD and their parents participated. Adolescents completed assessments of pain characteristics, pain acceptance, mindfulness, and QOL. Parents completed instruments measuring demographic and disease variables and parent psychological flexibility. RESULTS: Pain variables were associated with protective factors in predicted directions. Adolescent acceptance and mindfulness were positively correlated with QOL. Parent psychological flexibility and adolescent QOL were not related. After controlling for demographic, pain, and disease variables, moderation analyses indicated that adolescent pain acceptance buffered the relation between SCD pain burden and QOL. Moderation analyses were not significant for adolescent mindfulness or parent psychological flexibility. CONCLUSIONS: Results suggest that strengths-based factors may play an important role for adolescents' QOL within the context of SCD pain. Interventions that enhance teenagers' ability to accept pain might be particularly useful to improve QOL in adolescents living with SCD pain.

RESUMEN

The NIMH Research Domain Criteria (RDoC) initiative aims to understand the mechanisms influencing psychopathology through a dimensional approach. Limited research thus far has considered potential racial/ethnic differences in RDoC constructs that are influenced by developmental and contextual processes. A growing body of research has demonstrated that racial trauma is a pervasive chronic stressor that impacts the health of Black Americans across the life course. In this review article, we examine the ways that an RDOC framework could allow us to better understand the biological embedding of racial trauma among Black Americans. We also specifically examine the Negative Valence System domain of RDoC to explore how racial trauma is informed by and can help expand our understanding of this domain. We end the review by providing some additional research considerations and future research directives in the area of racial trauma that build on the RDoC initiative.

RESUMEN

Identifying the mechanisms linking early experiences, genetic risk factors, and their interaction with later health consequences is central to the development of preventive interventions and identifying potential boundary conditions for their efficacy. In the current investigation of 412 African American adolescents followed across a 20-year period, we examined change in body mass index (BMI) across adolescence as one possible mechanism linking childhood adversity and adult health. We found associations of childhood adversity with objective indicators of young adult health, including a cardiometabolic risk index, a methylomic aging index, and a count of chronic health conditions. Childhood adversities were associated with objective indicators indirectly through their association with gains in BMI across adolescence and early adulthood. We also found evidence of an association of genetic risk with weight gain across adolescence and young adult health, as well as genetic moderation of childhood adversity's effect on gains in BMI, resulting in moderated mediation. These patterns indicated that genetic risk moderated the indirect pathways from childhood adversity to young adult health outcomes and childhood adversity moderated the indirect pathways from genetic risk to young adult health outcomes through effects on weight gain during adolescence and early adulthood.

RESUMEN

The current study investigated the relationship between trauma exposure and psychopathology in a sample of predominately African-American women of low socioeconomic status (SES). Women (N = 7430) were recruited from medical clinics at two large public hospitals in Atlanta, GA, from 2005 to 2017. Women were assessed for sociodemographics, life-course trauma burden, posttraumatic stress disorder (PTSD), and major depressive disorder (MDD) utilizing self-report and structured clinical interview assessments. The effects of trauma exposure on current and lifetime PTSD and MDD were examined. Ninety-one percent of women reported trauma exposure, 83% reported a monthly household income of less than $2000, and 41% reported a history of arrest. Regarding psychiatric diagnoses, 30.8% met the criteria for probable MDD, and 32.3% met the criteria for probable PTSD. History of childhood abuse and total lifetime trauma significantly increased PTSD and depressive symptoms with additional incremental trauma exposure. PTSD and depressive symptom scores (95% CI) increased from 5.5 (5.0-6.1) and 8.4 (7.9-9.0) in the no trauma group to 20.8 (20.1-21.5) and 20.4 (19.7-21.2), respectively, in those exposed to four or more types of trauma. These results show high rates of adult and childhood trauma exposure, PTSD, MDD, and an additive effect of lifetime trauma exposure on the development of PTSD and MDD in a sample of low SES African-American women. These findings bring light to the high psychiatric symptom burden in this population and call for increased availability of interventions to address symptoms as well as policies aimed at reducing trauma exposure across the lifespan.

RESUMEN

OBJECTIVES: Experiences of racial discrimination are common for Black Americans and have been associated with depression and sleep disturbance, factors likely involved in the insidious development of health disparities. The current study replicates these associations and examines longitudinal linkages. METHOD: Black American couples (men: N = 248, Mage = 40, SD = 9; women: N = 277, Mage = 37, SD = 7) and their children, aged 9 to 14 (N = 276, Mage = 11, SD = 1), completed measures of experiences of racial discrimination, depressive symptoms, and sleep problems at baseline and 8-month follow-up. In separate analyses for men, women, and youth, we examined concurrent and prospective associations of racial discrimination with depressive symptoms and sleep problems, then used longitudinal indirect effect models to examine whether depressive symptoms in response to racial discrimination led to increased sleep problems, or vice versa. RESULTS: Racial discrimination was associated concurrently with depressive symptoms and sleep problems for all family members. Prospective associations were also found with depressive symptoms and sleep problems in fathers and youth, and sleep problems in mothers. Longitudinal models showed significant indirect effects of racial discrimination on change in sleep problems through depressive symptoms for fathers and mothers, and a similar, but nonsignificant, pattern in youth. There were no indirect effects on change in depressive symptoms through sleep problems. CONCLUSIONS: Persistent associations of racial discrimination with depressive symptoms and sleep problems reflect a lasting impact of racial discrimination. Because discrimination's effects on depression may contribute to increased sleep problems over time, interventions that buffer the effects of discrimination on depressive symptoms may also reduce sleep problems.

RESUMEN

In the current study, we used a sample of predominantly African-American women with high rates of trauma exposure (N = 434) to examine psychometric properties of the Personality Inventory for DSM-5-Brief Form (PID-5-BF). We compared model fit between a model with five correlated latent factors and a higher-order model in which the five latent factors were used to estimate a single "general pathology" factor. Additionally, we computed estimates of internal consistency and domain interrelations and examined indices of convergent/discriminant validity of the PID-5-BF domains by examining their relations to relevant criterion variables. The expected five-factor structure demonstrated good fit indices in a confirmatory factor analysis, and the more parsimonious, higher-order model was retained. Within this higher-order model, the first-order factors accounted for more variance in the criterion variables than the general pathology factor in most instances. The PID-5-BF domains were highly interrelated (rs = .38 to .66), and convergent/discriminant validity of the domains varied: Negative Affectivity and Detachment generally showed the hypothesized pattern of relations with external criteria, while Antagonism and Disinhibition displayed less consistent and discriminant relations. Results are discussed in terms of the costs and benefits of using brief pathological trait measures in samples characterized by high levels of psychopathology.

RESUMEN

There is evidence that the more frequent, severe, and chronic posttraumatic stress disorder (PTSD) symptomatology experienced by Black compared to White individuals cannot be explained by disparities in socioeconomic status or trauma exposure. One factor that may be important to consider is racial discrimination, which is associated with numerous negative mental health outcomes yet has not been studied in the context of interpersonal traumas for Black women. This study aims to fill this gap by examining the independent and interactive roles of racial discrimination and interpersonal trauma in predicting PTSD symptoms in a community sample of trauma-exposed, Black women (n = 292). Consistent with the previous literature, we found that more frequent experiences of racial discrimination were associated with more severe PTSD symptoms overall (r = .34) and by symptom cluster. Furthermore, we found a significant interaction between experiences of racial discrimination and experiences of interpersonal trauma (b = .46, 95%CI[.04, .88], SE = .28; ΔR2 = .01, p = .03) such that the association between PTSD symptoms and interpersonal trauma was stronger at higher (+1 SD above the mean) levels of racial discrimination. This pattern was replicated for most PTSD symptom clusters. These results suggest that racial discrimination experiences exacerbate the association between interpersonal traumatic experiences and PTSD symptoms among Black women.

RESUMEN

BACKGROUND: Immune dysregulation has been widely observed in those with posttraumatic stress disorder (PTSD). An individual's immune response is shaped, in part, by the highly polymorphic Human Leukocyte Antigen (HLA) locus that is associated with major psychiatric disorders such as schizophrenia, major depression and bipolar disorder. The aim of the current study was to investigate the association between common HLA alleles and PTSD. METHODS: Genome-wide association data was used to predict alleles of 7 classical polymorphic HLA genes (A, B, C, DRB1, DQA1, DQB1, DPB1) in 403 lifetime PTSD cases and 369 trauma exposed controls of African ancestry. Association of HLA allelic variations with lifetime PTSD was analyzed using logistic regression, controlling for ancestry, sex and multiple comparisons. The effect of HLA alleles on gene expression was assessed by weighted correlation network analysis (WGCNA), using 353 subjects with available expression data. Enrichment analysis was performed using anRichment to identify associated pathways of each module. RESULTS: HLA-B*58:01 (p = 0.035), HLA-C*07:01 (p = 0.035), HLA-DQA1*01:01 (p = 0.003), HLA-DQB1*05:01 (p = 0.009) and HLA-DPB1*17:01 (p = 0.017) were more common in PTSD cases, while HLA-A*02:01 (p = 0.026), HLA-DQA1*05:05 (p = 0.011) and HLA-DRB1*11:01 (p < 0.001) were more frequent in controls. WGCNA was used to explore expression patterns of the PTSD related alleles. Gene expression modules of PTSD-related HLA alleles were enriched in various pathways, including pathways related to immune and neural activity. CONCLUSIONS: To the best of our knowledge, this is the first study to report an association of HLA alleles with PTSD. Altogether, our results support the link between the immune system, brain and PTSD.

RESUMEN

OBJECTIVES: Despite the abundance of research aimed at quantifying the impact of racism on the mental and physical health of African Americans, results remain inconclusive largely because of challenges with operationalization, as well as conflation with the concept of racial discrimination, which may be more readily assessed. The purpose of the current study was to: (a) determine whether racial discrimination had an impact on the degree of alcohol use and binge drinking among African American emerging adults, and if so, (b) determine whether perceived stress linked to racially discriminatory experiences moderated these associations. METHOD: We used a series of hierarchical regressions to examine associations among racial discrimination, perceived stress, and degree of alcohol consumption in a sample of African American emerging adults in the southeast (n = 235). RESULTS: We found that the association between racial discrimination and degree of alcohol consumption (alcohol use and binge drinking) was strongest among individuals who reported greater levels of perceived stress linked to racial discrimination experiences. This association, however, was not significant for individuals who reported lower levels of perceived stress in response to racial discrimination.
