Abstract
Community violence exposure (CVE) and its health impact is a public health crisis. Violent crime has steadily increased over recent years and has disproportionately affected Black communities. Emerging adulthood (18-29 years old) is a vulnerable period of development and Black emerging adults may be at increased risk for negative physical and mental health consequences from CVE. This integrative review was conducted to evaluate available evidence on health outcomes in Black emerging adults exposed to CVE. This review appraised published studies (2012-2022) addressing physical and mental health outcomes of Black emerging adults with CVE. Articles were identified using structured search terms in several databases (CINAHL, PubMed, PsycInfo, and Web of Science), a gray literature search, and citation mining. A total of 177 studies were identified for screening and 19 studies met inclusion criteria and were included in the review. The majority of studies found a significant positive association between CVE and adverse mental (n = 12) and physical (n = 7) health outcomes. CVE appears to have both mental and physical health consequences for Black emerging adults. Given that violent crime disproportionately increased in Black communities and Black people are more likely to develop chronic health conditions at younger ages, more work is needed to elucidate the relationship between CVE and health outcomes.

Abstract
Racism-based experiences among Black African immigrants in the United States are a growing concern due to the prevalence of these events and risk for negative health (mental, behavioral, and physical) outcomes. This integrative review appraised published studies (2012-2023) addressing the relationship between racism-based experiences and adverse health for Black African immigrants. Articles were identified using structured search terms in several databases (APA PsycINFO, CINAHL, PubMed, Web of Science), Google Scholar, and citation mining. A total of fourteen studies met the inclusion criteria. Studies found a significant positive association between racism-based experiences and adverse mental (n = 9), behavioral (n = 3), and physical (n = 2) health outcomes. Racism-based experiences appear to have mental, behavioral, and physical health consequences for Black African immigrant adults. Given the growing population of Black African immigrants in the United States, more work is needed to elucidate the relationship between racism-based experiences and negative health outcomes.

Abstract
Despite custodial grandchildren's (CG) traumatic histories and risk for psychological difficulties, knowledge is scant regarding the frequencies, types, and consequences es of adverse childhood experiences (ACEs) they have encountered. We examined self-reported ACEs via online surveys with 342 CG (ages 12 to 18) who were recruited to participate in an RCT of a social intelligence training program. ACEs were assessed by 14 widely used items, and risk for internalizing (ID) and externalizing (ED) difficulties were measured using 80th percentile cut-offs on the Strengths and Difficulties Questionnaire. Classification and regression tree analyses included all 14 ACEs (along with CG gender and age) as predictors of ID and ED risk separately. Given possible comorbidity, analyses were run with and without the other risk type as a predictor. Less than 9% of CG self-reported no ACEs, 48.6% reported two to five ACEs, and 30.5 % reported ≥ 6. Irrespective of ED risk, bullying from peers strongly predicted ID risk. ED risk was peak among CG who also had risk for ID. Without ID risk as a predictor, ED risk was highest among CG who were emotionally abused, not lived with a substance abuser, and encountered neighborhood violence. The frequency and types of ACEs observed were alarmingly higher than those among the general population, suggesting that many CG have histories of trauma and household dysfunction. That a small number of ACEs among the 14 studied here were significant predictors of ID and ED risk challenges the widespread belief of a cumulative dose ACE effect.

Abstract
Structural racism inflicts a disproportionate burden of stress and trauma within Black communities, resulting in physical and mental health inequities that impact Black youth. Yet few multilevel interventions exist to address these deeply rooted inequities from a preventive standpoint, and even fewer are informed by the participatory input of the impacted communities. To bridge these gaps, we developed a community-based prevention strategy that promotes agency and active resistance to structural racism, Youth Empowered Advocating for Health (YEAH), and implemented it across various settings. We outline the development, implementation, and expansion of YEAH as a tool for promoting optimal health among Black communities. Lastly, we discuss lessons learned and offer a framework outlining key principles for prevention scientists to partner with Black youth and engage them in translational science to address structural racism. This framework is aimed at driving policies, practices, and procedures that promote equitable and sustainable change for and with Black communities.

Abstract
There is limited existing research on whether specific combinations of Adverse Childhood Experiences (ACEs) are associated with different psychiatric disorders among adolescents with ADHD. This study aimed to address this gap by identifying classes of ACEs and examining their association with behavioral problems, anxiety, and depression in adolescents with ADHD aged 11-17 (n = 1,806), using data from the 2018 National Survey of Children's Health (NSCH). A latent class analysis revealed a four-class solution: (1) low-risk ACEs (61.6%), (2) moderate-risk ACEs (25.2%), (3) high discrimination and neighborhood violence exposure (7.6%), and (4) high-risk ACEs (5.6%). The "high-risk ACEs" and the "high discrimination and neighborhood violence exposure" class showed a higher likelihood of behavioral problems and depression, and anxiety and depression respectively. These findings provide some insight into the ACE patterns that are more likely to be associated with mental health problems among adolescents with ADHD.

Abstract
Exposure to violence remains a significant issue for children in the United States. The COVID-19 pandemic exacerbated many of these exposures. Violence unequally impacts children of color and lesbian, gay, bisexual, transgender, and questioning youth. Pediatricians can and must continue to advocate and intervene to decrease pediatric violence exposure and its effects.

Abstract
African Americans have a higher prevalence of obesity and obesity-related diseases than other racial/ethnic groups; among persons with serious mental illness (SMI), African Americans fare worse as well. This qualitative study focused on the perceptions of African Americans with SMI in regard to 1) their experiences with diet and exercise behaviors post trauma and 2) how diet and exercise programming can address trauma. A community-based participatory research (CBPR) team developed the interview guide, research protocols, and conducted three focus groups. The team used thematic analysis to analyze the data. Participant (N = 27) responses on the experience of trauma were coded into the following themes: 1) emotional eating, 2) appetite loss, 3) hesitancy to exercise due to community violence, 4) staying home due to mental health symptoms, and 5) substance use. Themes around how programming can address trauma included: 1) support, 2) communication, 3) strategies to avoid trauma, and 4) engagement in programming. Findings suggest the need for human service professionals to infuse trauma-informed communications and practices throughout programming, incorporate peer-led services and address concerns related to community violence.

Abstract
Experiences of and exposures to violence impact older adolescents and young adults in a myriad of ways. While typically conceptualized as interpersonal, other forms of violence, namely, structural and symbolic, can be harmful to development for this population. This study utilized qualitative methodologies, including ethnographic field notes and interviews, to capture the ways in which 12 young persons aged 16 to 20 from Philadelphia experience and conceptualize multiple forms of violence across neighborhood contexts. In total, 85 interviews and over 100 hours of field observations were conducted and analyzed using thematic analysis. Findings from this study demonstrate that multiple forms of violence are experienced and impact how young adults make meaning of their life experiences. Importantly, our study explores how these forms of violence occur in tandem across contexts. Whereby, aspects of young adult development and well-being are shaped by violence across the micro, meso, and macro systems with which they interact. Implications of this work include adapting Bronfenbrenner’s Ecological Systems Theory to include multiple forms of violence so that practitioners and researchers can better understand how forms of violence are enacted and the associated impacts on young adults.

Abstract
In this study, academic researchers partnered with Black youth to engage in critical analysis of the intersection between racism and community violence to promote anti-racist social action that advances health equity. Through youth participatory action research, we examined perspectives and experiences of Black youth to develop a shared understanding of how to approach community violence prevention with an anti-racist lens. Thirteen youth from Kansas City and Atlanta who identified as Black or African American participated in a photovoice project to explore the intersection of racism and community violence. Youth generated photo assignments, took photos that reflected the assignment, shared their photos as a group, and chose one photo to explore in depth each week using a structured method to guide photo-discussion. Qualitative analysis of youth photo-discussions identified themes related to Black youth's experiences of racism at multiple levels and identified suggestions for anti-racist interventions, including promoting Black history knowledge and nurturing Black mentoring relationships. Grounded in these findings, we propose an anti-racist approach to community violence prevention among Black youth that engages Black youth as equitable partners to build from their expertise and strengths in developing comprehensive solutions.

Abstract
Firearm violence is a leading cause of morbidity and mortality among young adults. Identification of intervention targets is crucial to developing and implementing effective prevention efforts. Hospital Violence Intervention Programs (HVIPs) have used a multiprong social care approach to mediate the cycle of interpersonal violence. One struggle continually encountered is how to change the conversation around the future. Speech patterns have been associated with health outcomes and overall behavior modification. During violence prevention efforts, young victims of violence say things such as ‘I’m living on borrowed time’ and ‘why should I worry about getting an education when I’ll likely die soon anyway?’ Such speech patterns may contribute to the cycle of violence and increase the likelihood of reinjury. Presented is a narrative review of the impact language has on health outcomes and how psychotherapy may be able to change thought patterns, alter language structure, and ultimately reduce risk of reinjury. The biopsychosocial model of health posits that a person’s health is dictated by a combination of biological, psychological, and social factors. By understanding that language exists in the personal context, it can serve as both an indicator and a tool for targeted interventions. Cognitive–behavioral therapy (CBT) works by retraining thought and speech patterns to affect change in emotion, physiology, and behavior. It is proposed here that CBT could be used in the HVIPs’ multidisciplinary case management model by involving trained psychotherapists. Language is an important indicator of a patient’s psychological state and approach to life-changing decisions. As such, language alteration through CBT could potentially be used as a novel method of injury prevention. This concept has not before been explored in this setting and may be an effective supplement to HVIPs’ success.

Abstract
The purpose of this study was to evaluate the mutual impact of community and individual factors on youth's perceptions of community safety, using structural equation modeling (SEM) conceptualized by syndemic theory. This study used survey data collected from a county wide sample of middle and high school students (N=25,147) in West Central Florida in 2015. The outcome variable was youth's perceptions of community safety. Predictors were latent individual and community factors constructed from 14 observed variables including gun accessibility, substance use, depressive symptoms, and multiple neighborhood disadvantage questions. Three structural equation models were conceptualized based on syndemic theory and analyzed in Mplus 8 using weighted least squares (WLS) estimation. Each model's goodness of fit was assessed. Approximately seven percent of youth reported feeling unsafe in their community. After model modifications, the final model showed a good fit of the data and adhered to the theoretical assumption. In the final SEM model, an individual latent factor was implied by individual predictors measuring gun accessibility without adult's permission (β=0.70), sadness and hopelessness (β=0.52), alcohol use (β=0.79), marijuana use (β=0.94), and illegal drug use (β=0.77). Meanwhile, a community latent factor was indicated by multiple community problems including public drinking (β=0.88), drug addiction (β=0.96), drug selling (β=0.97), lack of money (β=0.83), gang activities (β=0.90), litter and trash (β=0.79), graffiti (β=0.91), deserted houses (β=0.86), and shootings (β=0.93). A second-order syndemic factor that represented the individual and community factors showed a very strong negative association with youth's safe perception (β=-0.98). This study indicates that individual risk factors and disadvantaged community conditions interacted with each other and mutually affected youth's perceptions of community safety. To reduce these co-occurring effects and improve safe perceptions among youth, researchers and practitioners should develop and implement comprehensive strategies targeting both individual and community factors.

Abstract
Community violence (CV) is a global public health problem due to its high frequency and severe consequences. Although CV is one of the leading causes of death among adolescents, little is known about the everyday CV situations that do not lead to death. This study aimed to estimate the frequency of exposure to and involvement in CV situations among adolescent students from public and private schools in the city of Rio de Janeiro, Brazil. This was a cross-sectional study of 693 individuals in their second year of high school selected through stratified multistage random sampling. Information about their exposure to and involvement in CV was collected through a self-completed multidimensional questionnaire in the classrooms. For approximately 30% of the adolescents, someone close to them had been murdered, and 40% had already seen the corpse of a victim of homicide. Seventeen percent reported having been directly involved in CV situations. Approximately 38%, 13%, and 25% had been victims of robberies, interpersonal aggression, and death threats to either themselves or their relatives, respectively. Many of these situations occurred more than once. In general, CV was more frequently reported by boys and by those who did not live with both parents. Adolescents from higher economic classes experienced more interpersonal aggression and felt a greater need to carry a gun. Those who belonged to the lower economic classes and studied in public schools were more exposed to lethal violence than other students. The results call attention to the very high percentage of adolescent students that are involved in CV situations as well as to the differences in violence rates among population subgroups. Such findings should be considered when planning CV prevention and management actions in schools and other socialization spaces for adolescents.

Abstract
OBJECTIVE Community violence exposure has been identified as a risk factor for Black youth suicide ideation. However, little is known about factors that protect community violence exposed youth against suicide ideation. The current study examined associations between knowledge of family member and peers' community violence exposure and Black youth's subsequent suicidal ideation, and investigated self-worth and social support as protective factors. METHOD Participants were a community sample of Black youth (N = 447, 47.4% female; Mage = 11.77, SD = 0.35) who reported about community violence exposure, self-worth, social support, and suicide ideation in grades 6 and 7. RESULTS Regression analyses revealed that grade 6 knowledge of family member and peers' community violence exposure was associated with increases in suicide ideation assessed in grade 7. Self-worth attenuated the association between knowledge of others' community violence exposure and suicide ideation for male adolescents. For female adolescents, social support attenuated the association between knowledge of others' community violence and suicide ideation. CONCLUSIONS Findings highlight the consequential impact of knowledge about community violence for Black youth's suicidal ideation. Enhancing protective factors for Black youth is an important target for intervening with exposure to violence and reducing suicide ideation.

Abstract
Introduction The exposome concept provides a framework to better incorporate the environment into the study of health and disease and has been defined by academics to encompass all lifetime exposures including toxicants, diet, and lifestyle choices. However, initial applications of the exposome concept have been less apt at measuring social determinants of health, focusing primarily on conventional environmental exposures and lifestyle choices that do not reflect the complex lived experience of many communities. To bring community voice into the exposome concept, the HERCULES Exposome Research Center and its Stakeholder Advisory Board co-developed the Exposome Roadshow. We present and discuss the resulting community-exposome definition to inform and improve exposome research. Materials and Methods Four communities from distinct areas across metro-Atlanta participated in separate 2-day Exposome Roadshow workshops with concept mapping. Aligned with a popular education approach in which community knowledge is used to work collectively for change, concept mapping provided a systematic method to collect and visualize community members' knowledge and create a shared understanding to take action. Community members brainstormed, sorted, and rated their responses to the prompt: "What in your environment is affecting your and your community's health?" Responses were analyzed and visually depicted by concept maps consisting of separate but interrelated clusters of ideas. Community members discussed and validated the maps, selecting a final map illustrating their community's exposome. Results A total of 118 community members completed concept mapping. On average communities identified 7 clusters to define their exposome. The resulting concept maps offer a community definition of the exposome. Five major themes arose across all four communities: conventional environmental concerns, built environment, social relationships, crime and safety, and individual health and behaviors. Discussion The resulting community-exposome definition demonstrates the importance of expanding the scope of exposures beyond traditional environmental influences to include the lived experience of individuals and communities. While newer exposome definitions align more closely with this community definition, traditional exposome methods do not routinely include these factors. To truly capture the totality of lifetime exposures and improve human health, researchers should incorporate community perspectives into exposome research.

Abstract
Exposure to interpersonal violence during childhood, a severe and often traumatic form of social stress, is an enduring problem that an emerging body of work suggests may be relevant to cardiometabolic health and the progression of cardiovascular disease (CVD) across the life course. Less is known about this association causally, and consequently, the biological mechanisms that may confer risk for, and resilience to, poor health outcomes in the aftermath of violence are not well understood. Drawing on recent theoretical insights and empirical research in both humans and non-human animal models, the current paper articulates a hypothesis for one way that childhood violence could get "under the skin" to influence CVD. Based on this emerging literature, one plausible way that childhood violence exposure could increase susceptibility to CVD in later life is by sensitizing stress-response neurobiology and immune processes that regulate and promote inflammation, which is a key pathogenic mechanism in CVD. This is inherently a developmental process that begins in early life and that unfolds across the life course, although less is known about the specific mechanisms through which this occurs. The goal of this paper is to articulate some of these plausible mechanisms and to suggest areas for future research that aims to reduce the burden of disease among individuals who are exposed to violence.

Abstract
This study examined the association between community violence exposure (CVE), sex without contraception, and adolescent pregnancy in Chicago. A self-administered, online survey was conducted among 15- to 19-year-old girls from the South and West sides of Chicago from October to March 2018. Participants were recruited via community organization partnerships and social media advertising. The survey included questions about CVE, sexual behaviors, and covariates that are known to contribute to sexual risk taking. CVE was measured via a validated index of seven questions that measured individual experiences with violence. Multivariable and logistic regression analyses were performed to examine the association between CVE, penile-vaginal intercourse without contraception, and ever being pregnant. The final sample included 644 girls. Levels of CVE were high: 62.87% of girls reported that a close friend or relative died because of violence and 41.60% were a victim of violence. Nearly half (48.69%) of girls had penile-vaginal intercourse and 6.01% had been pregnant. For each standard deviation increase in CVE score, the odds of penile-vaginal intercourse without contraception (odds ratio [OR] = 1.69, 95% confidence interval [CI] = [1.27, 2.25]) and the odds of ever being pregnant (OR = 1.87, 95% CI = [1.36, 2.57]) increased. These results remained significant when adjusting for demographic, psychosocial, institutional, and interpersonal factors. Findings suggest that girls in Chicago who are exposed to higher levels of community violence have an increased likelihood of experiencing penile-vaginal intercourse without contraception and teenage pregnancy, even when adjusting for other predictors to teenage pregnancy.

Abstract
Over 25% of U.S. children are witness to traumatic intrafamilial or community violence each year, and sleep medicine and developmental research jointly suggest that trauma-exposed youth experience more sleep disturbance than their non-exposed counterparts. Sleep medicine literature emphasizes physical and social environmental factors affecting sleep, and trauma literature underscores children's seeking out physically and emotionally safe and predictable environments during trauma recovery. This study employed a hermeneutic phenomenological framing to explore the lived experiences of 65 violence-exposed children and families, and to examine how youths' social and physical sleep environments facilitated or impeded sleep in the aftermath of trauma. Children's sleep experiences following violence exposure shared two primary essences of experience: a) navigating external threats that agitated sleep after trauma; and b) exercising agency over sleep and related environments to restabilize emotional security. Clinicians and social services coordinators working with children and families are uniquely positioned to indicate sleep assessments as part of treatment following trauma, and to also facilitate identification of tangible, sleep-supportive and changeable factors in sleep environments.

Resting-State Functional Connectivity of the Central Executive Network Moderates the Relationship Between Neighborhood Violence and Proinflammatory Phenotype in Children. Biol Psychiatry 2021; 90:165-172.

Abstract
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.

Non-fatal gun violence and community health behaviors: A neighborhood analysis in Philadelphia. J Behav Med 2021; 44:833-841.

Abstract
Research shows that community violence is associated with an array of negative health outcomes, yet no study has examined the specific association between different types of gun violence and collective health behaviors in local neighborhoods. Using data from neighborhoods in the city of Philadelphia, this study examines the association between total, fatal, and non-fatal gun violence and measures of physical inactivity, obesity, sleep, and smoking. We find the rate of non-fatal shootings is associated with a composite measure of health behaviors, net of all neighborhood-level covariates and general community violence. Ancillary analyses show that non-fatal shootings are particularly associated with physical inactivity and obesity. Notably, fatal shootings are not associated with any behavioral health measure after accounting for nonlethal shootings. The results support improved data collection efforts to measure non-fatal shootings across the U.S. and greater attention to the collective health consequences of gun violence in local communities.

Abstract
Neighborhood violence is associated with a range of health consequences but little is known about the biological processes involved. Research in disease pathogenesis has identified low-grade inflammation as a process that, beginning in the first decades of life, is both induced by chronic stress and a contributor to multiple cardiometabolic diseases that present throughout the lifecourse. Previous research has examined whether neighborhood violence is associated with inflammatory biomarkers, but has been limited to cytokine indicators of inflammation. In a sample of adolescents (n = 203) residing in Chicago, we tested cross-sectional associations between neighborhood violence and cellular and cytokine indicators of inflammation. Neighborhood-level violence was measured in multiple ways (as murder rates of Census block groups and as the sum of homicides within 1 and ½ mile zones) in the areas surrounding where youth lived and attended school. At the individual level, violence exposure was measured by self-report (direct victimization, witnessing violence, and/or victimization of family or friends in the past year). Adolescents residing in high-violence neighborhoods evidenced higher numbers of pro-inflammatory classical (CD14++CD16-) monocytes relative to those in less violent neighborhoods. In contrast, neighborhood-level violence was not consistently associated with cytokine levels across different model specifications. Self-reported violence exposure was also not consistently associated with inflammatory biomarkers. Neighborhood-level violence and self-reported violence exposure interacted, such that the positive association between neighborhood-level violence and classical monocytes was observed only among adolescents who reported being exposed to violence. Associations were largely specific to the neighborhoods in which youth lived as opposed to those in which they attended school. Findings provide the first evidence that youth residing in high-violence neighborhoods show mobilization of classical monocytes, suggesting a pro-inflammatory mechanism through which contextual stressors such as neighborhood violence may compromise health.

Abstract
Experiencing violence has been associated with negative health outcomes. The objectives of this study were to determine whether experiencing violence is associated increased support service needs and suboptimal general health indicators. In addition, we explore the relationship between these and perceived social support among a select sample of urban predominantly male adults in Baltimore City. A cross-sectional survey was conducted among 187 adults being seen in one of seven urban partner agencies participating in a parent HIV prevention and treatment demonstration project. Associations were examined using a multivariable logistic regression model, adjusting for the clinic site at which the client was being seen as well as age and gender identity. There was a significant amount of violence experienced by this population; 131 (72%) reported having seen someone be physically assaulted, and 89 (49%) had been physically assaulted without a weapon. Direct victimization from violence was associated with a threefold increased odds of needing housing and mental health/substance use services. Exposure to violence was associated with a threefold increase in needing housing and mental health/substance use services, and with sub-optimal health status. Perceived social support was associated with 30% decreased reports of experiencing violence. In conclusion, our select sample of urban adults report having experienced high rates of violence, and this is associated with increased support service needs as well as suboptimal perceived health status. Incorporating care for the effects of experiencing violence as well as social service needs are important in optimizing the health of urban populations.

Abstract
BACKGROUND Exposure to violence, which is experienced at disproportionally higher levels by black versus white youth, is associated with disruptions in sleep and elevated cardiovascular risk. Further, poor sleep hygiene is associated with insulin resistance. However, research to date examining disruptions in sleep and cardiovascular risk in African-American adolescents has not taken the impact of exposure to violence into account, nor considered how gender might affect patterns of association. The present study addressed this gap by testing a path model linking exposure to community violence, sleep disruption, and insulin resistance in a sample of African-American adolescents and evaluating model fit across gender. METHOD African-American adolescents (N = 107; 56% female; Mage = 14.29, SD = 1.17) completed structured interviews at home and provided a blood sample after fasting overnight. RESULTS The model fit connecting exposure to violence with sleep disruption and insulin resistance, adjusting for depressive symptoms and body mass index z score, was excellent. Multiple group analysis indicated gender differences in model fit. Path analysis revealed significant positive associations between exposure to violence and sleep disruption and sleep disruption and insulin resistance for females but not males. CONCLUSION These data indicate that low-income, urban African-American female adolescents who witness violence and experience sleep disruptions may already be at elevated risk for health problems compared with their male counterparts. Additional research should attempt to replicate and explicate the underlying reasons for the gender differences observed here, with the goal of improving health and disrupting the path leading to health disparities.

Abstract
Housing is a major pathway through which health disparities emerge and are sustained over time. However, no existing unified conceptual model has comprehensively elucidated the relationship between housing and health equity with attention to the full range of harmful exposures, their cumulative burden and their historical production. We synthesized literature from a diverse array of disciplines to explore the varied aspects of the relationship between housing and health and developed an original conceptual model highlighting these complexities. This holistic conceptual model of the impact of housing on health disparities illustrates how structural inequalities shape unequal distribution of access to health-promoting housing factors, which span four pillars: 1) cost (housing affordability); 2) conditions (housing quality); 3) consistency (residential stability); and 4) context (neighborhood opportunity). We further demonstrate that these four pillars can lead to cumulative burden by interacting with one another and with other structurally-rooted inequalities to produce and reify health disparities. We conclude by offering a comprehensive vision for healthy housing that situates housing's impact on health through a historical and social justice lens, which can help to better design policies and interventions that use housing to promote health equity.

Abstract
Adverse childhood experiences (ACEs) have historically included child maltreatment, household dysfunction, and other critical issues known to impact children negatively. Although youth experiences with violence are broadly captured in some ACE measures, youth exposure to violence involving a gun has not been included specifically in the operationalizing, and therefore scientific study, of ACEs. There are numerous implications of this omission, including limiting access to ACE interventions that are currently available and resources for individuals who have been exposed to gun violence. Thus, and given the persistent prevalence of gun violence in the US, we conducted a systematic review of the literature over the past two decades on the assessment of and response to ACEs and gun violence. Eighty-one journal articles across four search engines met our inclusion criteria. Our findings provide evidence that youth gun violence exposure should be classified as an ACE. In addition to increasing access to resources for youth affected by gun violence, these findings may improve the likelihood of funding and research into gun violence, with direct implications for prevention and intervention efforts.

Abstract
OBJECTIVE There is a well-documented link between child maltreatment and poor health across the lifespan. This provides a strong case for ongoing research with youth involved in the child welfare system to reduce negative outcomes and support resilience while being inclusive of youth voices. However, detailed inquiries about maltreatment history and health consequences may cause re-experiencing of events and psychological distress for study participants. Data that accounts for different contexts, such as severity of maltreatment history and current trauma symptomatology, have been limited in considering the question of potential harms to youth who participate in research-especially longitudinal studies. METHODS This study compared self-reported impact of research participation against maltreatment history and current post-traumatic stress symptomatology among a randomly selected group of adolescents (< 18 years old) in the child protection service (CPS) system. RESULTS Adolescents who report more serious child maltreatment and current trauma symptom severity reported higher scores on distress questions from pre- to post-assessment participation. Critically, participants who were more negatively impacted by study involvement also reported greater benefit from study involvement. CONCLUSION The increase in both negative and positive impact does not shift the risk/reward ratio for participation, as risks alone do not increase for this vulnerable group of CPS involved youth. These results are consistent with previous findings from studies involving non-CPS populations and underlies the importance of empirical data to address the question of change in the risk/reward ratio and what factors might play a role in any change. This information can inform inclusion/exclusion criteria for future research with these vulnerable populations, thereby reducing the risk of distress among study participants.

Abstract
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.

Abstract
PURPOSE OF REVIEW Multiple respiratory diseases, including asthma and chronic obstructive pulmonary disease (COPD), display significant socioeconomic and racial/ethnic disparities. The objective of this review is to evaluate the evidence supporting a link between disproportionate environmental exposures and these health disparities. RECENT FINDINGS Studies suggest that various co-occurring factors related to the home environment, neighborhood environment, non-modifiable individual factors, and individual behaviors and attributes can increase or modify the risk of adverse respiratory outcomes among socioeconomically-disadvantaged and racially/ethnically diverse populations. Pollutants in the home environment, including particulate matter, nitrogen dioxide, and pesticides, are elevated among lower socioeconomic status populations and have been implicated in the development or exacerbation of respiratory-related conditions. Neighborhood crime and green space are socioeconomically patterned and linked with asthma outcomes through psychosocial pathways. Non-modifiable individual factors such as genetic predisposition cannot explain environmental health disparities but can increase susceptibility to air pollution and other stressors. Individual behaviors and attributes, including obesity and physical activity, contribute to worse outcomes among those with asthma or COPD. SUMMARY The root causes of these multifactorial exposures are complex, but many likely stem from economic forces and racial/ethnic and economic segregation that influence the home environment, neighborhood environment, and access to healthy foods and consumer products. Critical research needs include investigations that characterize exposure to and health implications of numerous stressors simultaneously, both to guard against potential confounding in epidemiological investigations and to consider the cumulative impact of multiple elevated environmental exposures and sociodemographic stressors on health disparities.
