RESUMEN

Importance: Upward mobility (via educational attainment) is highly valued, but longitudinal associations with mental and physical health among Black youths are less understood. Objective: To examine associations of childhood family disadvantage and college graduation with adult mental and physical health in Black youths followed up into adulthood. Design, Setting, and Participants: This longitudinal, prospective cohort study of Black youths from the state of Georgia who were studied for 20 years (ages 11 to 31 years) was conducted between 2001 and 2022. Participants for this study were drawn from the Strong African American Healthy Adults Program. Data analysis was conducted from April 2023 to January 2024. Exposures: Family economic disadvantage (measured during the adolescent years) and college graduation (indicating upward mobility). Main Outcomes and Measures: Primary outcomes included mental health, substance use, and physical health. Mental health included a composite of internalizing and disruptive problems (anxiety, depression, anger, aggressive behaviors, and emotional reactivity). Substance use included a composite of smoking, drinking, and drug use. Physical health included metabolic syndrome (MetS) and proinflammatory phenotypes (immune cells mounting exaggerated cytokine responses to bacterial challenge and being insensitive to inhibitory signals from glucocorticoids). Mental and physical health measures were taken at age 31 and during the adolescent years. Linear and logistic regression analyses, as well as mediated moderation analyses, were conducted. Results: The study population consisted of 329 Black youths (212 women [64%]; 117 men [36%]; mean [SD] age at follow-up, 31 [1] years). Compared with those who did not graduate college, those who graduated from college had 0.14 SD fewer mental health problems (b = -1.377; 95% CI, -2.529 to -0.226; ß = -0.137; P = .02) and 0.13 SD lower levels of substance use (b = -0.114; 95% CI, -0.210 to -0.018; ß = -0.131; P = .02). Residualized change scores revealed that college graduates showed greater decreases from age 16 to 31 years in mental health problems (b = -1.267; 95% CI, -2.360 to -0.174; ß = -0.133; P = .02) and substance use problems (b = -0.116; 95% CI, -0.211 to -0.021; ß = -0.136; P = .02). For physical health, significant interactions between childhood family disadvantage and college completion emerged in association with MetS (OR, 1.495; 95% CI, 1.111-2.012; P = .008) and proinflammatory phenotype (b = 0.051; 95% CI, 0.003 to 0.099; ß = 0.131; P = .04). Among youths growing up in disadvantaged households, college completion was associated with a 32.6% greater likelihood of MetS (OR, 3.947; 95% CI, 1.003-15.502; P = .049) and 0.59 SD more proinflammatory phenotype (mean difference, 0.249, 95% CI, 0.001 to 0.497; P = .049). Conversely, among those from economically advantaged backgrounds, college completion was correlated with lower MetS and less proinflammatory phenotype. Findings held after controlling for body mass index at age 19 years. Conclusions and Relevance: In this longitudinal cohort study of Black youths, graduating from college was associated with an adult profile of better mental health but poorer physical health among those from economic disadvantage. These findings suggest that developing interventions that foster healthy outcomes across multiple life domains may be important for ensuring that striving for upward mobility is not accompanied by unintended cardiometabolic risk.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Importance: Racial discrimination undermines the mental health of Black adolescents. Preventive interventions that can attenuate the effects of exposure to racial discrimination are needed. Objective: To investigate whether participation in the Strong African American Families (SAAF) program moderates Black adolescents' depressive symptoms associated with experience of racial discrimination. Design, Setting, and Participants: This secondary analysis used data from a community-based randomized clinical trial of SAAF (SAAF vs no treatment control). Participants were followed up at 10, 22, and 34 months after the baseline assessment. Assessment staff were blind to participant condition. Participants in this trial lived in 7 rural counties in Georgia. SAAF was delivered at local community centers. Eligible families had a child aged 11 to 12 years who self-identified as African American or Black. The joint influence of random assignment to SAAF and exposure to racial discrimination was investigated. Data were analyzed from September 2022 to March 2023. Intervention: SAAF is a 7-session (14 hours) family skills training intervention that occurs over 7 weeks. Small groups of caregivers and their adolescents participate in a structured curriculum targeting effective parenting behavior, adolescent self-regulation, and Black pride. Main Outcomes and Measures: The main outcome was adolescent-reported depressive symptoms, assessed at 34 months via the 20-item Center for Epidemiologic Studies Depression Scale for Children. Results: Of 825 families screened randomly from public school lists, 472 adolescents (mean [SD] age, 11.6 years; 240 [50.8%] female) were enrolled and randomized to SAAF (252 participants) or a no treatment control (220 participants). Exposure to racial discrimination at age 13 years was associated with increased depressive symptoms at age 14 years (ß = 0.23; 95% CI, 0.13 to 0.34; P < .001). Interaction analyses indicated that the experimental condition significantly moderated the association of racial discrimination with depressive symptoms: (ß = -0.27; 95% CI, -0.47 to -0.08; P = .005). Probing the interaction with simple slopes at ±SD revealed that for the control group, racial discrimination was significantly associated with depressive symptoms (ß = 0.39; 95% CI, 0.23 to 0.54; P < .001), while for the SAAF group, there was no association between racial discrimination and depressive symptoms (ß = 0.12; P = .09). Conclusions and Relevance: This randomized clinical trial found that the SAAF intervention reduced the incidence of racism-associated mental health symptoms among Black adolescents. SAAF is recommended for dissemination to health care practitioners working with rural Black adolescents. Trial Registration: ClinicalTrials.gov Identifier: NCT03590132.

RESUMEN

Background: This study examined how experiences with discrimination relate to inflammation, a key biological pathway in mental and physical illnesses, and whether associations are moderated by gender across two samples of adolescents of color. Methods: Study 1 was a longitudinal study of 419 African American adolescents assessed on discrimination (ages 19-20), with trajectories of biomarkers of low-grade inflammation (C-reactive protein and soluble urokinase plasminogen activator receptor) measured from ages 25 to 29. Study 2 was a cross-sectional study of 201 eighth graders of color assessed on discrimination and mechanistic indicators of a proinflammatory phenotype: 1) in vitro studies of immune cells' inflammatory cytokine responses to stimuli; 2) in vitro studies of cells' sensitivity to anti-inflammatory agents; 3) circulating numbers of classical monocytes, key cellular drivers of low-grade inflammation; and 4) a composite of six biomarkers of low-grade inflammation. Results: Interactions of discrimination by gender were found across both studies. In study 1, African American males experiencing high discrimination showed increasing trajectories of soluble urokinase plasminogen activator receptor over time (p < .001). In study 2, adolescent boys of color experiencing greater discrimination evinced a more proinflammatory phenotype: larger cytokine responses to stimuli (p = .003), lower sensitivity to anti-inflammatory agents (p = .003), higher numbers of classical monocytes (p = .008), and more low-grade inflammation (p = .003). No such associations were found in females. Conclusions: Discrimination is a pressing societal issue that will need to be addressed in efforts to promote health equity. This study suggests that adolescent males of color may be particularly vulnerable to its effects on mental health-relevant inflammatory processes.

RESUMEN

A large body of research demonstrates that inflammation is involved in physical health problems that cause substantial morbidity and early mortality. Given inflammation's role in the etiology of chronic diseases, pediatric scientists have begun to study childhood factors that presage elevation of inflammatory biomarkers later in life. The purpose of this study was to test hypotheses designed to determine whether early adolescent emotionally intense and low attention temperaments forecast (a) inflammation at ages 25 and 29 years and (b) worsening levels of inflammation between these two data points. Toward this end, 307 Black children from the rural southeastern United States participated in an 18-year longitudinal study (mean age at baseline, 11.2 years) to determine whether and how early adolescent's behavioral styles or emotionally intense and low attention temperaments may be associated with absolute and worsening levels of inflammation in young adulthood. When children were 11-13 years of age, different teachers at each age provided assessments of emotionally intense and low attention temperaments. Thus, multiple measures of the same temperament constructs were obtained across 3 years for each participant. At age 25, participants provided data on their self-regulation abilities. Peripheral blood was collected at ages 25 and 29 years from which inflammation was quantified, using soluble urokinase plasminogen activator (suPAR), the proinflammatory cytokines interleukin (IL) IL-6, IL-10, and tumor necrosis factor-alpha (TNF-α). Covariates associated with inflammation in prior studies were also assessed; these included socioeconomic risk, gender, cigarette smoking, body mass index (BMI), adverse childhood experiences (ACEs), depressive symptoms, and medication use. An early adolescent emotionally intense temperament was associated directly with higher suPAR and cytokine levels at age 29, and with worsening cytokine levels between ages 25 and 29. A low attention temperament was associated with suPAR levels at age 29. Collectively, these observations highlight pathways that could underlie health risks associated with early adolescent temperaments. The findings suggest that emotionally intense and low-attention early adolescent temperaments forecast higher and worsening inflammation levels across young adulthood.

RESUMEN

Importance: School belonging has important implications for academic, psychological, and health outcomes, but the associations between racial disparities in school belonging and health have not been explored to date. Objective: To examine associations between school-level racial disparities in belonging and cardiometabolic health into adulthood in a national sample of Black and White children, adolescents, and young adults. Design, Setting, and Participants: Prospective cohort study of a US national sample of 4830 Black and White students (National Longitudinal Study of Adolescent Health) followed up for 13 years. The study was conducted from 1994 to 1995 for wave 1 and in 2008 for wave 4. Data were analyzed from June 14 to August 13, 2021. Main Outcomes and Measures: School-level racial disparities in belonging at baseline were calculated as the mean level of school belonging for Black students minus the mean level of school belonging for White students at the school that they attended when they were aged 12 to 20 years. Diabetes and metabolic syndrome were measured as outcomes for these same participants at 24 to 32 years of age. Results: The study included 4830 students. For wave 1, mean (SD) age was 16.1 (1.7) years, and for wave 4, 29.0 (1.7) years. A total of 2614 (54.1%) were female, 2219 were non-Hispanic Black (45.9%), and 2611 were non-Hispanic White (54.1%). Among Black students, attending a school with a greater Black-White disparity in school belonging (more negative scores) was associated with an increased risk for diabetes (odds ratio, 0.66 [95% CI, 0.46-0.95]) and more risk factors for metabolic syndrome (rate ratio, 0.95 [95% CI, 0.90-1.00]) in adulthood 13 years later. These associations persisted above individual-level controls (age, sex, and body mass index) and school-level controls (school size, percentage of Black students, and percentage of Black teachers) and were not explained by either an individual's own perception of school belonging or the mean level of belonging across the whole school. Conclusions and Relevance: In this prospective cohort study of US students, racial disparities in school belonging were associated with risks for diabetes and metabolic syndrome in Black students. Among students, fostering a more equal sense of school belonging across racial groups may have implications for health disparities in the cardiometabolic domain into adulthood.

RESUMEN

Childhood poverty is associated with elevated internalizing symptoms. Nevertheless, some children exposed to poverty evince remarkable resilience, demonstrating lower than expected levels of psychological distress. However, recent work suggests that coping with adversity can lead to undesirable physical health consequences. Specifically, successful adaptation in the context of early adversity, including socioeconomic disadvantage, appears to be associated with elevated chronic physiological stress and ill health. The current study adds to this emerging literature by examining in a longitudinal context whether low levels of internalizing symptoms in the face of childhood poverty is accompanied by elevated chronic physiological stress (allostatic load) during childhood, as well as over time from childhood to adulthood. Results (n = 341; M=9.2 years, 49 % female; 94 % Caucasian) show that childhood poverty was prospectively associated with higher allostatic load during adolescence, controlling for baseline allostatic load. Furthermore, greater duration of childhood poverty led to steeper, more elevated allostatic load trajectories from childhood to adulthood, for youth with lower levels of internalizing symptoms. Efforts to manage adverse sequelae of early adversity likely yield a complex array of benefits and costs.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

A scientific consensus is emerging that children reared in risky family climates are prone to chronic diseases and premature death later in life. Few prospective data, however, are available to inform the mechanisms of these relationships. In a prospective study involving 323 Black families, we sought to determine whether, and how, childhood risky family climates are linked to a potential risk factor for later-life disease: increases in cellular aging (indexed by epigenetic aging). As hypothesized, risky family climates were associated with greater outflows of the stress hormones epinephrine and norepinephrine at ages 19 and 20 years; this, in turn, led to increases in cellular aging across ages 20-27 years. If sustained, these tendencies may place children from risky family climates on a trajectory toward the chronic diseases of aging.

RESUMEN

BACKGROUND: Neighborhood violence increases children's risk for a variety of health problems. Yet, little is known about biological pathways involved or neural mechanisms that might render children more or less vulnerable. Here, we address these questions by considering whether neighborhood violence is associated with the expression of a proinflammatory phenotype and whether this relationship is moderated by resting-state functional connectivity (rsFC) of the central executive network (CEN). METHODS: The study involved 217 children (13.9 years old; 66.4% female; 36.9% Black; 30.9% Latinx), enrolled in eighth grade and reassessed 2 years later. At time 1, geocoding was used to estimate murder frequency in children's neighborhoods, and functional magnetic resonance imaging was used to characterize CEN rsFC. At both visits, children gave antecubital blood for ex vivo studies, where leukocytes were incubated with stimulators and inhibitors of inflammation, and cytokine production was measured. RESULTS: Consistent with our hypotheses, the relationship between neighborhood murder and inflammatory activity was moderated by CEN rsFC. Among children with lower rsFC, neighborhood violence covaried with a proinflammatory phenotype, reflected in larger cytokine responses to triggering stimuli and lower sensitivity to inhibitory agents. These associations were generally not apparent for children with higher rsFC, although occasionally they ran in the opposite direction. The same patterns were apparent 2 years later. CONCLUSIONS: These results advance the understanding of neighborhood violence and its relationship with processes involved in the initiation and resolution of inflammation. They also deepen understanding of variability in children's immunologic responses to stress and suggest that the CEN may be a neurobiological contributor to resilience.

RESUMEN

Importance: Some Black adolescents who frequently experience racial discrimination develop mental health problems. Protective caregiving may buffer adolescents from the negative mental health outcomes associated with experiencing racial discrimination. Objective: To examine if participation in programs that enhance protective caregiving will attenuate the positive association between Black adolescents' encounters with discrimination and subsequent increases in mental health problems. Design, Setting, and Participants: This secondary analysis used data from 2 randomized clinical trials testing family-centered prevention programs: the Strong African American Families-Teen (SAAF-T) program and the Adults in the Making (AIM) program. The programs were implemented in community locations convenient for participants in 12 rural Georgia counties. For the SAAF-T trial, Black adolescents and their primary caregivers were recruited from 2007 to 2008. In the AIM trial Black adolescents and their primary caregivers were recruited from 2006 to 2007. Data for this study were analyzed from June to August 2020. Exposures: Adolescents provided data at baseline on the frequency of their encounters with racial discrimination. Treatment group participants in each trial took part in a family-centered prevention program designed to prevent substance use and mental health problems. SAAF-T is a 5-session, 10-hour psychosocial intervention for families with a Black adolescent aged 14 to 16 years. AIM is a 6-session, 12-hour psychosocial intervention for families with a Black youth who is a high school senior. Main Outcomes and Measures: The primary outcomes were mental health problems, including conduct problems and depression or anxiety symptoms. Results: The SAAF-T study included 502 Black adolescents (mean [SD] age, 16.0 [0.6] years; 281 [56.0%] girls), including 252 randomized to the intervention and 250 randomized to the control, and the AIM trial included 367 Black adolescents (mean [SD] age, 17.7 [0.8] years; 217 [59.1%] girls and women), including 187 randomized to the intervention and 180 randomized to the control. Adolescents assigned to the SAAF-T intervention group who frequently experienced discrimination at baseline evinced fewer subsequent increases in conduct problems (incident risk ratio, 0.530 [95% CI, 0.340 to 0.783]). Adolescents assigned to the AIM intervention group who frequently experienced discrimination at baseline evinced fewer subsequent increases in conduct problems (mean difference, -0.361 [95% CI, -0.577 to -0.144]) and fewer subsequent increases in depression or anxiety symptoms (mean difference, -0.220 [95% CI -0.402 to -0.038]). Moderated mediation analyses suggested that enhanced protective caregiving was partially responsible for all observed interaction effects (indirect effect: SAAF-T conduct problems, -0.063 [95% CI, -0.127 to -0.001]; AIM conduct problems, -0.048 [95% CI, -0.095 to -0.001]; AIM depression or anxious symptoms, -0.036 [95% CI, -0.074 to 0]). Conclusions and Relevance: This secondary analysis of 2 randomized clinical trials found that participation in family-centered preventive interventions attenuated the association between frequent exposure to discriminatory behaviors and subsequent mental health problems. Notably, all but 1 of the treatment and moderated-mediation findings were reproduced across the SAAF-T and AIM trials.

RESUMEN

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.
