RESUMO
Although the biological embedding model of adversity proposes that stressful experiences in childhood create a durable proinflammatory phenotype in immune cells, research to date has relied on study designs that limit our ability to make conclusions about whether the phenotype is long-lasting. The present study leverages an ongoing 20-year investigation of African American youth to test research questions about the extent to which stressors measured in childhood forecast a proinflammatory phenotype in adulthood, as indicated by exaggerated cytokine responses to bacterial stimuli, monocyte insensitivity to inhibitory signals from hydrocortisone, and low-grade inflammation. Parents reported on their depressive symptoms and unsupportive parenting tendencies across youths' adolescence. At age 31, youth participants (now adults) completed a fasting blood draw. Samples were incubated with lipopolysaccharide and doses of hydrocortisone to evaluate proinflammatory processes. Additionally, blood samples were tested for indicators of low-grade inflammation, including IL-6, IL-8, IL-10, and TNF-α, and soluble urokinase plasminogen activator receptor. Analyses revealed that parental depression across youths' adolescence prospectively predicted indicators of proinflammatory phenotypes at age 31. Follow-up analyses suggested that unsupportive parenting mediated these associations. These findings suggest that exposure to parental depression in adolescence leaves an imprint on inflammatory activity that can be observed 20 years later.

Individuals with substance use problems show lower executive control and alterations in prefrontal brain systems supporting emotion regulation and impulse control. A separate literature suggests that heightened inflammation also increases risk for substance use, in part, through targeting brain systems involved in executive control. Research on neural and inflammatory signaling in substance use, however, has occurred in parallel. Drawing on recent neuroimmune network models, we used fMRI to examine the relationships between executive control-related brain activity (as elicited by an n-back working memory task), peripheral inflammation, as quantified by inflammatory cytokines and C-reactive protein (CRP), and substance use for the past month in 93 participants [mean age = 24.4 (SD = 0.6)]. We operationalized low executive control as a neural inefficiency during the n-back task to achieve normative performance, as reflected in higher working memory-related brain activity and lower activity in the default mode network (DMN). Consistent with prediction, individuals with low executive control and high inflammation reported more substance use over the past month, controlling for behavioral performance on the n-back, sex, time between assessments, body-mass-index (BMI), and personal socioeconomic status (SES) (interaction between inflammation and working memory-related brain activity, b = 0.210, p = 0.005; interaction between inflammation and DMN, b = -0.219, p < 0.001). Findings suggest that low executive control and high inflammation may be associated with higher substance use. This has implications for understanding psychological, neural, and immunological risk for substance use problems and the development of interventions to target each of these components.

Depression is a serious public health problem, and adolescence is an 'age of risk' for the onset of Major Depressive Disorder. Recently, we and others have proposed neuroimmune network models that highlight bidirectional communication between the brain and the immune system in both mental and physical health, including depression. These models draw on research indicating that the cellular actors (particularly monocytes) and signaling molecules (particularly cytokines) that orchestrate inflammation in the periphery can directly modulate the structure and function of the brain. In the brain, inflammatory activity heightens sensitivity to threats in the cortico-amygdala circuit, lowers sensitivity to rewards in the cortico-striatal circuit, and alters executive control and emotion regulation in the prefrontal cortex. When dysregulated, and particularly under conditions of chronic stress, inflammation can generate feelings of dysphoria, distress, and anhedonia. This is proposed to initiate unhealthy, self-medicating behaviors (e.g. substance use, poor diet) to manage the dysphoria, which further heighten inflammation. Over time, dysregulation in these brain circuits and the inflammatory response may compound each other to form a positive feedback loop, whereby dysregulation in one organ system exacerbates the other. We and others suggest that this neuroimmune dysregulation is a dynamic joint vulnerability for depression, particularly during adolescence. We have three goals for the present paper. First, we extend neuroimmune network models of mental and physical health to generate a developmental framework of risk for the onset of depression during adolescence. Second, we examine how a neuroimmune network perspective can help explain the high rates of comorbidity between depression and other psychiatric disorders across development, and multimorbidity between depression and stress-related medical illnesses. Finally, we consider how identifying neuroimmune pathways to depression can facilitate a 'next generation' of behavioral and biological interventions that target neuroimmune signaling to treat, and ideally prevent, depression in youth and adolescents.

BACKGROUND: Low socioeconomic status (SES) is a risk factor for poor outcomes across development. Recent evidence suggests that, although psychosocial resilience among youth living in low-SES households is common, such expressions of resilience may not extend to physical health. Questions remain about when these diverging mental and physical health trajectories emerge. The current study hypothesized that skin-deep resilience - a pattern wherein socioeconomic disadvantage is linked to better mental health but worse physical health for individuals with John Henryism high-effort coping - is already present in childhood. METHODS: Analyses focus on 165 Black and Latinx children (Mage = 11.5) who were free of chronic disease and able to complete study procedures. Guardians provided information about their SES. Children reported on their John Henryism high-effort coping behaviors. They also provided reports of their depressed and anxious mood, which were combined into a composite of internalizing symptoms. Children's cardiometabolic risk was captured as a composite reflecting high levels of systolic or diastolic blood pressure, waist circumference, HbA1c, triglycerides, and low high-density lipoprotein cholesterol. RESULTS: Among youth who reported using John Henryism high-effort coping, SES risk was unrelated to internalizing symptoms and was positively associated with cardiometabolic risk. In contrast, for youth who did not engage in high-effort coping, SES risk was positively associated with internalizing symptoms and was unrelated to cardiometabolic risk. CONCLUSIONS: For youth with high-effort coping tendencies, socioeconomic disadvantage is linked to cardiometabolic risk. Public health efforts to support at-risk youth must consider both mental and physical health consequences associated with striving in challenging contexts.

Skin-deep resilience, in which youth overcome adversity and achieve success in psychological and academic domains but at a cost to their physiological well-being, has been documented in late adolescence and adulthood. However, its potential to emerge at earlier developmental stages is unknown. To address this gap, secondary data analyses were executed using waves 1 and 2 of the Adolescent Brain Cognitive Development study (n = 7712; ages 9-10 years at baseline [mean: 9.92; SD = 0.63]; 47.1% female; 66.1% White, 13.4% Black, and 20.6% Hispanic). The results indicated high levels of executive functioning were associated with improved psychological and behavioral outcomes at one-year follow-up. However, for racial and ethnic minority (i.e., Black or Hispanic) youth from disadvantaged neighborhoods, high levels of executive functioning were also associated with accelerated pubertal development. No significant interaction was observed among White youth. The findings suggest the skin-deep resilience pattern may be evident in early adolescence.

Health disparities by socioeconomic status (SES) have been extensively documented, but less is known about the physical health implications of achieving upward mobility. This article critically reviews the evolving literature in this area, concluding that upward mobility is associated with a trade-off, whereby economic success and positive mental health in adulthood can come at the expense of physical health, a pattern termed skin-deep resilience. We consider explanations for this phenomenon, including prolonged high striving, competing demands between the environments upwardly mobile individuals seek to enter and their environments of origin, cultural mismatches between adaptive strategies from their childhood environments and those that are valued in higher-SES environments, and the sense of alienation, lack of belonging, and discrimination that upwardly mobile individuals face as they move into spaces set up by and for high-SES groups. These stressors are hypothesized to lead to unhealthy behaviors and a dysregulation of biological systems, with implications for cardiometabolic health.

The present study investigated developmental pathways that can contribute to chronic disease among rural African Americans. With a sample of 342 African American youth (59% female) from the southeastern United States followed for nearly two decades (2001-2019), we examined the prospective association between family poverty during adolescence (ages 11-18) and insulin resistance (IR) in young adulthood (ages 25-29) as well as underlying biological and psychosocial mechanisms. Results indicated family poverty during adolescence forecast higher levels of IR in young adulthood, with accelerated immune cell aging at age 20 partially mediating this association. Serial mediational models confirmed the hypothesized pathway linking family poverty, perceived life chances, cellular aging, and IR. Findings provide empirical support for theorized developmental precursors of chronic disease.

African American emerging adults face unique contextual risks that place them at heightened risk for poor psychosocial outcomes. The purpose of this study was to identify profiles of contextual risks among rural African American emerging adults and determine how risk profiles relate to psychosocial outcomes. Our representative sample included 667 fifth graders who live in the rural South and were followed from preadolescence into emerging adulthood. Contextual risks were assessed at ages 19-21 years via six indicators: perceived stress, daily stress, community disadvantage, parent-child conflict, racial discrimination, and childhood trauma. Four psychosocial variables were also assessed at ages 19-21 years: self-regulation, racial identity, parent support, and friend support. Psychosocial outcomes were assessed at age 25 years: education, substance use, future orientation, depressive symptoms, and externalizing behaviors. Latent profile analysis results indicated that the sample could be characterized by three patterns of contextual risk: low contextual risk, high contextual risk, and high contextual risk-childhood trauma. Risk profiles were associated with psychosocial outcomes, with the childhood trauma and high-risk profiles faring worse than the low-risk profile. Further, childhood trauma was particularly predictive of worse outcomes for emerging adults. Findings highlight the need for research and prevention programs that mitigate the effects of contextual risks on psychosocial outcomes for African American emerging adults in rural areas.

Attachment experiences are thought to contribute to physical health across the lifespan. Evidence suggests that attachment style may serve as a protective factor for individuals' physical health by mitigating the negative effects of social and environmental risk factors. In the present study, we evaluated how attachment styles may moderate the link between African American adolescents' exposure to neighborhood poverty and accelerated cellular aging in young adulthood. Analyses revealed that allostatic load at age 19 mediated the association between neighborhood poverty in adolescence and changes in cellular aging from age 20 to 27. Notably, attachment avoidance (but not attachment anxiety) moderated this association, such that allostatic load was only associated with faster cellular aging for individuals who were high in avoidance. These findings suggest that allostatic load may give rise to faster cellular aging, but these detrimental effects of allostatic load can be offset by young adults' effective use of attachment figures.

Biological aging is a common root for multiple diseases causing morbidity and mortality, and trajectories of aging may start early in life. This study was designed to examine whether a universal family-based substance use preventive intervention to enhance self-control and reduce substance use would also result in reductions in biological aging among Black youth from the rural South. The Adults in the Making (AIM) program is a randomized controlled trial with six 2-h sessions for Black youth. The 216 youths agreeing to provide blood at age 22 included 114 who had received the AIM intervention and 102 who assigned to the control group. We examined accelerated DNA methylation (DNAm)-based aging using a recently developed measure, "GrimAge," that has been shown to predict the risk of early mortality and that is known to be more strongly affected by substance use than other DNAm-based aging indices. Relative to those randomly assigned to the control group, those receiving the intervention demonstrated significantly enhanced self-control, slower increases in substance use, and reduced Grim aging at age 22. Using a bootstrapping method with 1000 replications, we found a significant indirect effect of AIM on reduced Grim aging through its effect on self-control and substance use. Sensitivity analyses examined effects using other indices of DNAm-based aging. These findings suggest that a family-based program designed to enhance rural Black youth's self-control can have beneficial effects on self-control, enhancing young adult health and health behavior, and ultimately decreased mortality risk.
El envejecimiento biológico es una causa común de varias enfermedades que causan morbilidad y mortalidad, y las trayectorias del envejecimiento pueden comenzar en las primeras etapas de la vida. Este estudio se diseñó para analizar si una intervención preventiva familiar y universal en el abuso de sustancias orientada a mejorar el autocontrol y a reducir el consumo de sustancias también tendría como resultado disminuciones del envejecimiento biológico entre jóvenes negros del sur rural. El programa Adults in the Making (AIM) es un ensayo controlado aleatorizado con seis sesiones de dos horas para jóvenes negros. Entre los 216 jóvenes que aceptaron dar sangre a los 22 años se encontraban 114 que habían recibido la intervención del AIM y 102 asignados al grupo de referencia. Analizamos el envejecimiento basado en la metilación acelerada del ADN (ADNm) usando un método de medición desarrollado recientemente que se llama "GrimAge", el cual, según se ha demostrado, predice el riesgo de mortalidad temprana y está más marcadamente afectado por el consumo de sustancias que otros índices de envejecimiento basados en el ADNm. En relación con las personas asignadas aleatoriamente al grupo de referencia, las que recibieron la intervención demostraron un autocontrol considerablemente mayor, aumentos más lentos de consumo de sustancias y un menor envejecimiento Grim a los 22 años. Utilizando un método de muestreo con reemplazamiento con 1000 reproducciones, hallamos un efecto indirecto significativo del AIM en un menor envejecimiento Grim mediante su efecto en el autocontrol y el consumo de sustancias. Los análisis de sensibilidad examinaron los efectos utilizando otros índices de envejecimiento basados en el ADNm. Estos resultados indican que un programa familiar diseñado para aumentar el autocontrol de los jóvenes negros de zonas rurales puede tener efectos beneficiosos en el autocontrol, mejorar la salud de los adultos jóvenes y su conducta con respecto a la salud y, finalmente, disminuir el riesgo de mortalidad.

OBJECTIVE: Field-based research on inflammation and health is typically limited to baseline measures of circulating cytokines or acute-phase proteins, whereas laboratory-based studies can pursue a more dynamic approach with ex vivo cell culture methods. The laboratory infrastructure required for culturing leukocytes limits application in community-based settings, which in turn limits scientific understandings of how psychosocial, behavioral, and contextual factors influence the regulation of inflammation. We aim to address this gap by validating two "field-friendly" cell culture protocols, one using a small volume of venous whole blood and another using finger-stick capillary whole blood. METHODS: We evaluated the performance of both protocols against a standard laboratory-based protocol using matched venous and capillary blood samples collected from young adults (n = 24). Samples were incubated with lipopolysaccharide and hydrocortisone, and the production of proinflammatory cytokines interleukin 1ß, interleukin 6, and tumor necrosis factor α was measured in response. RESULTS: Comparisons indicate a high level of agreement in responses across the protocols and culture conditions. The overall correlation in results was 0.88 between the standard and small-volume protocols and 0.86 between the standard and capillary blood protocols. Repeatability for the small-volume and capillary blood protocols was high, with mean coefficients of variation across five replicates of 6.2% and 5.4%, respectively. CONCLUSIONS: These results demonstrate the feasibility of culturing cells and quantifying the inflammatory response to challenge outside the laboratory, with a wide range of potential applications in biobehavioral research in community-based and remote field settings.

This study tested relationships between racial inequalities in the school system-specifically, the disproportionate punishment of Black students-and life outcomes for Black youths, along with moderating psychological factors. In an 18-year longitudinal study of 261 Black youths (ages 11-29), we investigated whether adult life outcomes varied as a function of adolescent self-control and academic achievement. We tested whether relationships were moderated by the racial climates of the high schools that youths attended, using administrative data on relative punishment rates of Black and White students. Among Black youths who attended schools that disproportionately punished Black students, high self-control in early adolescence presaged higher academic orientation in late adolescence, which in turn predicted higher educational attainment, higher income, and better mental health in adulthood. However, among these same youths, higher academic orientation forecasted higher adult insulin resistance, a key process in cardiometabolic disease. These findings suggest that achieving successes in life in the face of racial inequalities may come at a physical health cost for Black youths.

Although violent crime has declined in recent decades, it remains a recurring feature of daily life in some neighborhoods. Mounting evidence indicates that such violence has a long reach, which goes beyond family and friends of the victim and undermines the health of people in the surrounding community. However, like all forms of adversity, community violence elicits a heterogeneous response: Some remain healthy, but others deteriorate. Despite much scientific attention, the neural circuitries that contribute to differential adaptation remain poorly understood. Drawing on knowledge of the brain's intrinsic functional architecture, we predicted that individual differences in resting-state connectivity would explain variability in the strength of the association between neighborhood violence and cardiometabolic health. We enrolled 218 urban youth (age 12-14 years, 66% female; 65% black or Latino) and used geocoding to characterize their exposure to neighborhood murder over the past five years. Multiple aspects of cardiometabolic health were assessed, including obesity, insulin resistance, and metabolic syndrome. Functional MRI was used to quantify the connectivity of major intrinsic networks. Consistent with predictions, resting-state connectivity within the central executive network (CEN) emerged as a moderator of adaptation. Across six distinct outcomes, a higher neighborhood murder rate was associated with greater cardiometabolic risk, but this relationship was apparent only among youth who displayed lower CEN resting-state connectivity. By contrast, there was little evidence of moderation by the anterior salience and default mode networks. These findings advance basic and applied knowledge about adaptation by highlighting intrinsic CEN connectivity as a potential neurobiological contributor to resilience.

This study tested the skin-deep resilience hypothesis - that low socioeconomic status (SES) youth who are working hard to succeed in life experience good psychological and educational outcomes but at a cost to their physical health - in a sample of monozygotic (MZ) twins. The National Longitudinal Study of Adolescent Health (Add Health) contained a sample of 226 MZ twin pairs at Wave 1 (M age = 16 years), of whom 141 pairs completed the Wave 4 assessment 13 years later (M age = 29 years). Family SES was measured at Wave 1 via income, education, and occupation. Conscientiousness was measured at Wave 4 as an indicator of those who were working hard to succeed in life. Outcomes measured at Wave 4 included low-grade inflammation (C-reactive protein, CRP), mental health (depression, problematic alcohol use), and academic success (educational attainment). A co-twin control design was utilized which directly compared within-twin differences in the association between conscientiousness and life outcomes. Main effects of between-twin conscientiousness were found such that higher levels of conscientiousness were associated with higher educational attainment, fewer symptoms of depression, and less problematic alcohol use, across all SES groups. An interaction between family SES and within-twin difference in conscientiousness was found for CRP, such that, among twins growing up in lower SES households, the twin with higher levels of conscientiousness had higher levels of CRP. These patterns provide support for the phenomenon of skin-deep resilience using a twin methodology that reduces the possibility of confounding by shared genetic and environmental factors.

OBJECTIVE: Children with low self-control who grow up in poverty are at elevated risk for living in poverty when they are adults. The purpose of this study was to further understanding of the intergenerational continuity of poverty by (a) examining the likelihood that children with low levels of self-control at age 11 earn less employment income and are more likely to live in poverty 14 years later, at age 25; and (b) determining, via a preventive intervention, whether enhancing supportive parenting during childhood will ameliorate these associations. METHODS: Parents and their 11-year-old children from 381 families participated in the Strong African American Families (SAAF) program or a control condition. Teachers assessed children's self-control at 11 years; parents reported their use of supportive parenting when children were 11 and 13 years; emerging adults provided data on cognitive and emotional self-control at 19, 20, and 21 years; and young adults indicated their employment income at 25 years. RESULTS: Significant two-way interactions were detected between children's self-control and prevention condition for employment income (b = -183.18, 95% CI [-363.82, -2.53], p < .05) and poverty status (b = 0.257, 95% CI [0.018, 0.497], p < .05). Low self-control at age 11 forecast less employment income and a greater likelihood of living in poverty among children in the control condition, but not among low self-control SAAF participants. Mediated moderation analyses confirmed that enhanced supportive parenting accounted for SAAF's effects on employment income (indirect effect = 63.057, 95% BCA [19.385, 124.748]) and poverty status (indirect effect = -0.071, 95% BCA [-0.165, -0.016]). CONCLUSIONS: This study is unique in using a randomized controlled trial to show that preventive interventions designed to enhance parenting and strengthen families can buffer the long-term economic consequences of low self-control.

Current adolescent substance use risk models have inadequately predicted use for African Americans, offering limited knowledge about differential predictability as a function of developmental period. Among a sample of 500 African American youth (ages 11-21), four risk indices (i.e., social risk, attitudinal risk, intrapersonal risk, and racial discrimination risk) were examined in the prediction of alcohol, marijuana, and cigarette initiation during early (ages 11-13), mid (ages 16-18), and late (ages 19-21) adolescence. Results showed that when developmental periods were combined, racial discrimination was the only index that predicted initiation for all three substances. However, when risk models were stratified based on developmental period, variation was found within and across substance types. Results highlight the importance of racial discrimination in understanding substance use initiation among African American youth and the need for tailored interventions based on developmental stage.

Children growing up in poverty are vulnerable to negative changes in the developing brain; however, these outcomes vary widely. We tested the hypothesis that receipt of supportive parenting would offset the association between living in poverty during adolescence and the connectivity of neural networks that support cognition and emotion regulation during young adulthood. In a sample of African American youths (N = 119) living in the rural South, poverty status and receipt of supportive parenting were assessed when youths were 11 to 13 and 16 to 18 years old. At age 25, resting-state functional connectivity of the central-executive and emotion-regulation neural networks was assessed using functional MRI. The results revealed that more years spent living in poverty presaged less connectivity in both neural networks among young adults who received low levels of supportive parenting but not among those who received high levels of such parenting.

Emerging evidence in psychology suggests a paradox whereby high levels of self-control when striving for academic success among minority youth can have physical health costs. This study tested the skin-deep resilience hypothesis in asthma- whether minority youth who are striving hard to succeed academically experience good psychological outcomes but poor asthma outcomes. Youth physician-diagnosed with asthma (Nâ¯=â¯276, M ageâ¯=â¯12.99; 155â¯=â¯White, 121â¯=â¯Black/Latino) completed interviews about school stress and a self-control questionnaire. Outcomes included mental health (anxiety/depression) and ex-vivo immunologic processes relevant to asthma (lymphocyte Th-1 and Th-2 cytokine production, and sensitivity to glucocorticoid inhibition). Physician contacts were tracked over a one-year follow-up. For minority youth experiencing high levels of school stress, greater self-control was associated with fewer mental health symptoms (betaâ¯=â¯-0.20, pâ¯<â¯.05), but worse asthma inflammatory profiles (larger Th-1 and Th-2 cytokine responses, lower sensitivity to glucocorticoid inhibition), and more frequent physician contacts during the one-year follow-up (beta's ranging from 0.22 to 0.43, p'sâ¯<â¯.05). These patterns were not evident in White youth. In minority youth struggling with school, high levels of self-control are detrimental to asthma inflammatory profiles and clinical outcomes. This suggests the need for health monitoring to be incorporated into academic programs to ensure that 'overcoming the odds' does not lead to heightened health risks in minority youth.

OBJECTIVE: Lifestyle variables such as drug use and excessive weight gain contribute to adult morbidity and mortality. This study was designed to determine whether participation in a preventive intervention designed to enhance supportive parenting can reduce drug use and body mass index (BMI) in young Black adults from disadvantaged neighborhoods. METHOD: This study was conducted in the rural southeastern United States. Black parents and their 11-year-old children (517 families) were assigned randomly to the Strong African American Families (SAAF) prevention trial or a control condition. Data assessing neighborhood socioeconomic status and supportive parenting were obtained when the youths were ages 11 and 16. When youths were ages 19-21 and 25, drug use and BMI were measured. RESULTS: As hypothesized, significant three-way interactions were detected among neighborhood disadvantage, prevention condition, and gender for BMI (B = 3.341, p = .009, 95% CI [0.832, 5.849]) and substance use (B = -0.169, p = .049, 95% CI [-0.337, -0.001]). Living in a disadvantaged neighborhood during adolescence was associated with increased drug use among young men in the control group (simple-slope = 0.215, p < .003) but not among those in the SAAF condition (simple-slope = 0.030, p = .650). Neighborhood disadvantage was associated with elevated BMI among young women in the control group (simple-slope = 3.343, p < .001), but not in the SAAF condition (simple-slope = 0.204, p = .820). CONCLUSIONS: The results suggest that participation during childhood in a preventive intervention to enhance supportive parenting can ameliorate the effects of life in a disadvantaged neighborhood on men's drug use and women's BMI across ages 19-25 years. These findings suggest a possible role for parenting enhancement programs in narrowing health disparities.

The psychosocial consequences of living with a depressed parent have been well characterized. Less well known, however, is how this exposure is predictive of later physical health problems. The present study evaluated how parental depression across youths' adolescence (ages 11-18) was associated with youth metabolic syndrome at age 25 (n = 391). Youth self-regulation and health behaviors were considered as possible moderators of the link between parental depression and youth metabolic syndrome. Analyses revealed that parental depression in adolescence was associated with a composite score reflecting metabolic syndrome components in early adulthood. Furthermore, self-regulation and health behaviors moderated this link, such that links between parental depression and the metabolic syndrome existed only for youth with low self-regulation or unhealthy behaviors.
