Neighborhood Racial and Economic Segregation and Disparities in Violence During the COVID-19 Pandemic

Effects of residential socioeconomic polarization on high blood pressure among nursing home residents

OBJECTIVE

Neighborhood concentration of racial, income, education, and housing deprivation is known to be associated with higher rates of hypertension. The objective of this study is to examine the association between tract-level spatial social polarization and hypertension in a cohort with relatively equal access to health care, a Veterans Affairs nursing home.

METHODS

41,973 long-term care residents aged ≥65 years were matched with tract-level Indices of Concentration at the Extremes across four socioeconomic domains. We modeled high blood pressure against these indices controlling for individual-level cardiovascular confounders.

RESULTS

We found participants who had resided in the most disadvantaged quintile had a 1.10 (95% 1.01, 1.19) relative risk of high blood pressure compared to those in the other quintiles for the joint measuring race/ethnicity and income domain.

CONCLUSIONS

We achieved our objective by demonstrating that concentrated deprivation is associated with worse cardiovascular outcomes even in a population with equal access to care. Measures that jointly consider economic and racial/ethnic polarization elucidate larger disparities than single domain measures.

Investigating the 2016 surge in firearm violence in Illinois, USA, through community-based organisations: a qualitative study

BACKGROUND

Illinois experienced a historic firearm violence surge in 2016 with a decline to baseline rates in 2018. This study aimed to understand this 2016 surge through the direct accounts of violence prevention community-based organisations (CBOs) in Illinois.

METHODS

We conducted semistructured interviews with 20 representatives from 13 CBOs from the south and west sides of greater Chicago metropolitan area. Interviews were audio recorded, coded and analysed thematically.

RESULTS

We identified lack of government-derived infrastructure and systemic poverty as the central themes of Illinois's 2016 firearm violence surge. Participants highlighted the Illinois Budget Impasse halted funding for violence prevention efforts, leading to 2016's violence. This occurred in the context of a strained relationship with the criminal justice system, where disengagement from police and mistrust in the justice system led victims and families to seek justice outside of the judicial system. Participants emphasised that systemic poverty and the obliteration of community support structures led to overwhelming desperation, which, in turn, increased risky behaviours perceived as necessary for survival. Participants disproportionately identified that this impacted the young people in their communities.

CONCLUSIONS

Lack of government-derived infrastructure and systemic poverty were the central themes of the 2016 firearm violence surge. The insights gained from the 2016 surge are applicable to understanding both current and future surges. CBOs focused on violence prevention offer insights into the context and conditions fuelling surges in the epidemic of violence.

The Effects of Interpersonal Violence on Sleep Following the COVID-19 Stay-at-Home Order

PURPOSE

Lack of sleep is a harm that can lead to chronic diseases ranging from diabetes to heart disease. We examined the exposure to interpersonal violence and its association with sleep, following the COVID-19 stay-at-home order.

DESIGN

Cross-sectional.

SETTING

Surveys were completed online and via paper-and-pencil in English and Spanish (N = 2049; RR = 68.4%).

SUBJECTS

Respondents were 18+ and residing in Chicago.

MEASURES

The Chicago Department of Public Health's "2022 Healthy Chicago Survey COVID-19 Social Impact Survey".

ANALYSIS

We developed two weighted models. Model 1 examined the effects of neighborhood violence on meeting the national sleep recommendation. Model 2 examined the effects of violence in the home among friends or family on meeting the sleep recommendation, incorporating additional predictors: victimization, stress, gender, race/ethnicity, household income, and general health. Odds ratios were estimated using multivariate logistic regression.

RESULTS

Exposure to neighborhood violence and sleep was not significant, but knowing a friend or family member who experienced violence or mistreatment in their home affected the odds of meeting the sleep recommendation (OR = .61, 95% CI = .44-.84). Non-Hispanic Blacks had 52% lower odds of meeting sleep recommendations (OR = .48, 95% CI = .37-.63).

CONCLUSION

Addressing the harms to sleep that followed COVID-19 should engage diverse stakeholders in implementing culturally responsive interventions to promote adequate sleep and prevent chronic disease.

Changes in Perceptions of the Near-Home Walking Environment Among US Adults-2015 and 2020 National Health Interview Survey

BACKGROUND

The built environments in which we work, live, and play can influence physical activity behaviors, and perceptions of these environments are associated with walking behavior. This study's objective is to compare national-level data on perceptions of the near-home walking environment from the 2015 and 2020 National Health Interview Survey.

METHODS

Adults in 2015 (n = 30,811) and 2020 (n = 29,636) reported perceptions of walkable supports (roads, sidewalks, paths, or trails; sidewalks on most streets), destinations (shops, stores, or markets; bus or transit stops; movies, libraries, or churches; places that help you relax, clear your mind, and reduce stress), and barriers to walking (traffic; crime; animals). Age-adjusted prevalence estimates, prevalence differences, and 95% confidence intervals were calculated overall and by demographic characteristics.

RESULTS

The reported prevalence of roads, sidewalks, paths, or trails for walking increased overall (85.3% in 2015 to 88.0% in 2020) and for many subgroups. Perceived places to walk to for relaxation, to clear your mind, and to reduce stress increased overall (72.1% in 2015 to 77.1% in 2020) and for all subgroups. Perceptions of crime as a barrier to walking decreased overall (12.5% in 2015 to 11.2% in 2020) and for some subgroups. From 2015 to 2020, the proportion of adults perceiving roads, sidewalks, paths, or trails; places to relax; and crime as a barrier to walking improved.

CONCLUSIONS

Continuing to monitor perceptions of the walking environment could contribute to progress toward national walking and walkability goals in the United States.

Why did US urban homicide spike in 2020? A cross-sectional data analysis for the largest American cities

Working with data about homicide victims and perpetrators from 50 of America's largest cities, we investigate the explanatory power of some familiar explanations for why murder in those cities rose sharply in 2020. The analysis reveals that the distribution of risk by race was essentially the same in 2020 as in 2019. That empirical finding challenges some theories of how racial tensions after the death of George Floyd may have driven homicide increases. Similarly, homicide growth was not concentrated in those cities with the greatest availability in 2020 of new and older guns, or among the cities that suffered the most from the COVID-19 pandemic. At a minimum, the cross-city outcomes should reduce confidence that some combination of "race, guns, and COVID-19" explains all of the most important aspects of what happened in 2020.

Structural Racism and Well-Being Among Young People in the U.S

INTRODUCTION

Structural racism has clear and pernicious effects on population health. However, there is a limited understanding of how structural racism impacts young people's well-being. The objective of this ecologic cross-sectional study was to assess the relationship between structural racism and well-being for 2,009 U.S. counties from 2010 to 2019.

METHODS

Population-based data on demographics, health, and other variables related to young people's ability to thrive are used to construct a previously validated composite index that serves as a proxy of young people's well-being. The index is regressed on several forms of structural racism (segregation, economic, and educational) both independently and jointly while accounting for county-fixed effects, time trends, and state-specific trends as well as weighting for child population. Data were analyzed from November 2021 through March 2023.

RESULTS

Higher levels of structural racism are associated with lower well-being. A 1-SD increase in Black-White child poverty disparity is associated with a -0.034 (95% CI= -0.019, -0.050) SD change in index score. When accounting for multiple structural racism measures, associations remain statistically significant. In joint models, only estimates for economic racism measures remain significant when additionally controlling for demographic, socioeconomic, and adult health measures (β= -0.015; 95% CI= -0.001, -0.029). These negative associations are heavily concentrated in counties where Black and Latinx children are overrepresented.

CONCLUSIONS

Structural racism-particularly of the kind that produces racialized poverty outcomes-has a meaningful adverse association with child and adolescent well-being, which may produce lifelong effects. Studies of structural racism among adults should consider a lifecourse perspective.

Social Vulnerability and Firearm Violence: Geospatial Analysis of 5 US Cities

BACKGROUND

Firearm violence is now endemic to certain US neighborhoods. Understanding factors that impact a neighborhood's susceptibility to firearm violence is crucial for prevention. Using a nationally standardized measure to characterize community-level firearm violence risk has not been broadly studied but could enhance prevention efforts. Thus, we sought to examine the association between firearm violence and the social, structural, and geospatial determinants of health, as defined by the Social Vulnerability Index (SVI).

STUDY DESIGN

In this cross-sectional study, we merged 2018 SVI data on census tract with shooting incidents between 2015 and 2021 from Baltimore, Chicago, Los Angeles, New York City, and Philadelphia. We used negative binomial regression to associate the SVI with shooting incidents per 1,000 people in a census tract. Moran's I statistics and spatial lag models were used for geospatial analysis.

RESULTS

We evaluated 71,296 shooting incidents across 4,415 census tracts. Fifty-five percent of shootings occurred in 9.4% of census tracts. In all cities combined, a decile rise in SVI resulted in a 37% increase in shooting incidents (p < 0.001). A similar relationship existed in each city: 30% increase in Baltimore (p < 0.001), 50% in Chicago (p < 0.001), 28% in Los Angeles (p < 0.001), 34% in New York City (p < 0.001), and 41% in Philadelphia (p < 0.001). Shootings were highly clustered within the most vulnerable neighborhoods.

CONCLUSIONS

In 5 major US cities, firearm violence was concentrated in neighborhoods with high social vulnerability. A tool such as the SVI could be used to inform prevention efforts by directing resources to communities most in need and identifying factors on which to focus these programs and policies.

Quasi-experimental study finding no localised gun crime or call reduction after gun buybacks in Philadelphia

INTRODUCTION

Gun buyback programmes have been popular in the USA since the 1970s. Studies show that they have no effect on citywide gun crime rates, but more microlevel examinations around gun buyback locations have not been conducted. This study tests for local effects of 34 Philadelphia, PA buyback events at 30 locations between 2019 and 2021.

METHODS

We analysed all gun-related crime events and gun-related calls for service attended by the police from 2019 to 2021. Multilevel models with an autoregressive residual structure were estimated on weekly gun crime and call event intensity (inverse distance weighted) totals across a range of distances (4000-8000 feet). Impacts of a gun buyback event were estimated for 1-4 weeks postevent.

RESULTS

Statistically significant weekly increases in gun event intensity are associated with seasonality and after the murder of George Floyd. Gun event intensity was not significantly affected by gun buybacks. Across 20 sensitivity tests of different distances and time periods (4000-8000 feet and between 1 and 4 weeks), gun buybacks were not statistically associated with any localised reduction in the intensity of gun crimes and calls.

CONCLUSIONS

Extant research has failed to uncover any effect of gun buybacks on citywide gun crime rates. The current results now contribute a lack of evidence at the local level to this literature. While gun buybacks remain popular with politicians and the public, this study adds to the ongoing question of whether buyback funds could be better spent more effectively.

Exploring changes in violence across two waves of the COVID-19 pandemic in Richmond, VA

The first wave of the COVID-19 pandemic carried with it an increase in violence in the United States and abroad. The proportion of violence cases involving firearms also increased during this time, yet little research has examined these effects using data from the second wave of COVID infections. Explanations for these documented increases in gun violence put forward by scholars include increased firearm purchases, alcohol consumption, unemployment, and organized crime activity. The current work examined these trends in Richmond, VA. We collected data on patients (N = 1744) presenting with violent injuries from 2018 to 2022 from the emergency department of a Level-1 Trauma Center in Richmond, VA. Data were coded on the basis of whether they presented before the pandemic, during the first wave, or during the second wave. Logistic binomial regressions revealed that the risk of gunshot wounds increased by 32% during the first wave and 44% during the second wave, relative to the pre-COVID period, but that the increase between the first and second wave was not significant. These findings held after controlling for victim age, race, sex, and injury severity. Further analyses revealed that these effects were specific to violent injury, as we found no increase in firearm use among self-injury cases. The heightened violence reported during the COVID-19 pandemic was also observed in Richmond, VA. Gun violence in particular increased over time as other forms of violence (i.e., assaults, stabbings, and self-harm) decreased.

Study protocol for a hybrid 1 effectiveness-implementation trial of Brief Skills Training in Affective and Interpersonal Regulation (Brief STAIR) and web-administered STAIR (webSTAIR) for posttraumatic stress disorder in integrated primary care

BACKGROUND

Posttraumatic stress disorder (PTSD) disproportionally affects low-income, racial and ethnic minoritized communities, where prevalence is high, yet access to evidence-based treatments (EBTs) is low. As such, there is a need to identify effective, feasible, and scalable interventions for PTSD. Stepped care approaches that include brief, low-intensity treatments are one approach to improving access yet have not been developed for adults with PTSD. Our study aims to test the effectiveness of a step one PTSD treatment in primary care while gathering information on implementation to maximize sustainability in the setting.

METHODS

This study will be conducted in integrated primary care in the largest safety net hospital in New England using a hybrid type 1 effectiveness-implementation design. Eligible trial participants are adult primary care patients who meet full or subthreshold criteria for PTSD. Interventions include Brief clinician-administered Skills Training in Affective and Interpersonal Regulation (Brief STAIR) versus web-administered STAIR (webSTAIR) during a 15-week active treatment period. Participants complete assessments at baseline (pre-treatment), 15 weeks (post-treatment), and 9 months (follow-up) post-randomization. We will assess feasibility and acceptability post-trial using surveys and interviews with patients, study therapists, and other key informants, and will assess the preliminary effectiveness of interventions in terms of PTSD symptom change and functioning.

CONCLUSION

This study will provide evidence for the feasibility, acceptability, and preliminary effectiveness of brief, low-intensity interventions in safety net integrated primary care, with the aim of including these interventions in a future stepped care approach to PTSD treatment.

Implications of the COVID-19 Pandemic on Interpersonal Violence Within Marginalized Communities: Toward a New Prevention Paradigm

During the COVID-19 pandemic, reports of domestic violence across the United States increased from 21% to 35%. Stay-at-home orders, designed to protect the public against the spread of COVID-19, along with heightened societal stressors as a result of the global pandemic, inadvertently increased rates of illicit drug and alcohol use, job loss, and isolation, resulting in increased stress and nonphysical (e.g., psychological, emotional, economic, technological) abuse that often escalated to physical violence. These processes were exacerbated in marginalized communities. These risks were heightened among Black women and Latinas, who experience high rates of domestic violence, long-standing distrust in law enforcement, and compromised self-reporting or anonymous reporting of abuse. We make recommendations for training key stakeholders (e.g., law enforcement, mental health clinicians, and public health care professionals) to facilitate the safety and well-being of domestic violence survivors and to better manage prevention or intervention efforts targeted at domestic violence. We make public health policy suggestions for individuals, communities, and governing structures. (Am J Public Health. 2023;113(S2):S149-S156. https://doi.org/10.2105/AJPH.2023.307289).

The New Crisis of Increasing All-Cause Mortality in US Children and Adolescents

This Viewpoint discusses increased rates in pediatric mortality by age and cause between 1999 and 2021.

Neighborhood Racial and Economic Privilege and Timing of Pubertal Onset in Girls

PURPOSE

Early puberty is associated with adverse health outcomes over the life course, and Black and Hispanic girls experience puberty earlier than girls of other racial/ethnic backgrounds. Neighborhood racial and economic privilege may contribute to these disparities by conferring differential exposure to mechanisms (e.g., stress, obesity, endocrine disruptors) underlying early puberty. We examined associations between neighborhood privilege, measured by the Index of Concentration at the Extremes (ICE), and age at pubic hair onset (pubarche) and breast development onset (thelarche) in a large multiethnic cohort.

METHODS

A cohort of 46,299 girls born 2005-2011 at Kaiser Permanente Northern California medical facilities were followed until 2021. Pubertal development was assessed routinely by pediatricians using the Sexual Maturity Rating scale. ICE quintiles for race/ethnicity, income, and income + race/ethnicity were calculated using American Community Survey 2010 5-year estimates and linked to census tract at birth. We fit multilevel Weibull regression models accommodating left, right, and interval censoring for all analyses.

RESULTS

ICE measures were monotonically associated with pubertal onset, with the strongest associations observed for ICE-race/ethnicity. Adjusting for maternal education, age at delivery, and parity, girls from the least versus most privileged ICE-race/ethnicity quintiles were at increased risk for earlier pubarche (hazard ratio: 1.30, 95% confidence interval: 1.21, 1.38) and thelarche (hazard ratio: 1.45, 95% confidence interval: 1.36, 1.54). These associations remained significant after adjusting for girls' race/ethnicity and childhood body mass index. Additionally, adjustment for ICE partially attenuated Black-White and Hispanic-White disparities in pubertal onset.

DISCUSSION

Neighborhood privilege may contribute to pubertal timing and related disparities.

Burden of firearm-related injuries as associated secondary diagnosis in the United States from National Inpatient Sample Dataset

There is little known about the differences, from the point of view of healthcare resource utilization, between non-fatal versus fatal firearm-related injuries. We undertook this research project utilizing the National Inpatient Sample (NIS) database to address this critical knowledge gap. Our aims for this study were to describe the patterns of FRI in the United States during the period of 2016-2019 and to evaluate the patient-centered outcomes in the survivor (non-fatal injuries) versus the non-survivor (fatal injuries) groups. We used the National Inpatient Sample (NIS) Database, 2016-2019 (5) (~ 20% of United States hospitalizations) to identify patients with an associated diagnosis of firearm-related injuries (FRI) [Gibson T et al (2016) in Agency for Healthcare Research and Quality 2016-02]. We found that the individuals from the lowest quartile of annual household income, males, young Americans, and racial minorities were disproportionally affected The non-survivor (fatal injuries) group had a shorter length of stay in the hospital by 5.1 days (95% CI - 5.64 to - 4.58, p value =  < 0.01), the higher median cost of hospitalization by $8903 (95% confidence interval $311.9 to $17,494.2, p value = 0.04), and a higher median cost of hospitalization per day by $41,576.74 (95% confidence interval $ 40,333.1 to $42,820.3, p value =  < 0.01). In conclusion, the individuals from the lowest quartile of annual household income, males, young Americans and racial minorities were disproportionally affected. Firearm-related injuries pose a persistent healthcare cost burden with the cumulative and per day cost of hospitalization for fatal injuries being significantly higher than the non-fatal injuries despite a shorter hospital LOS.

Analyzing Child Firearm Assault Injuries by Race and Ethnicity During the COVID-19 Pandemic in 4 Major US Cities

This cross-sectional study examines changes in rates and disparities of fatal and nonfatal firearm assaults among children in New York, Los Angeles, Chicago, and Philadelphia before and during the COVID-19 pandemic.

An intersectional analysis of historical and contemporary structural racism on non-fatal shootings in Baltimore, Maryland

Introduction Non-fatal shooting rates vary tremendously within cities in the USA. Factors related to structural racism (both historical and contemporary) could help explain differences in non-fatal shooting rates at the neighbourhood level. Most research assessing the relationship between structural racism and firearm violence only includes one dimension of structural racism. Our study uses an intersectional approach to examine how the interaction of two forms of structural racism is associated with spatial non-fatal shooting disparities in Baltimore, Maryland. Methods We present three additive interaction measures to describe the relationship between historical redlining and contemporary racialized economic segregation on neighbourhood-level non-fatal shootings. Results Our findings revealed that sustained disadvantage census tracts (tracts that experience contemporary socioeconomic disadvantage and were historically redlined) have the highest burden of non-fatal shootings. Sustained disadvantage tracts had on average 24 more non-fatal shootings a year per 10 000 residents compared with similarly populated sustained advantage tracts (tracts that experience contemporary socioeconomic advantage and were not historically redlined). Moreover, we found that between 2015 and 2019, the interaction between redlining and racialized economic segregation explained over one-third of non-fatal shootings (approximately 650 shootings) in sustained disadvantage tracts. Conclusion These findings suggest that the intersection of historical and contemporary structural racism is a fundamental cause of firearm violence inequities in Baltimore. Intersectionality can advance injury prevention research and practice by (1) serving as an analytical tool to expose inequities in injury-related outcomes and (2) informing the development and implementation of injury prevention interventions and policies that prioritise health equity and racial justice.

Relationships, resources, and political empowerment: community violence intervention strategies that contest the logics of policing and incarceration

Community violence-defined as unsanctioned violence between unrelated individuals in public places-has devastating physical, psychological, and emotional consequences on individuals, families, and communities. Immense investments in policing and incarceration in the United States have neither prevented community violence nor systemically served those who have been impacted by it, instead often inflicting further harm. However, the logics that uphold policing and incarceration as suitable or preventative responses to community violence are deeply ingrained in societal discourse, limiting our ability to respond differently. In this perspective, we draw from interviews with leading voices in the field of outreach-based community violence intervention and prevention to consider alternative ways to address community violence. We begin by demonstrating that policing and incarceration are distinguished by practices of retribution, isolation, and counterinsurgency that are counterproductive to the prevention of community violence. Then, we identify alternative practices of outreach-based community violence intervention and prevention that include (1) fostering safety nets through relationships among individuals, families, and neighborhoods, (2) fighting poverty and increasing access to resources, and (3) building political capacity among organizations to transform the broader systems in which they are embedded. They also include accountability practices that are preventative and responsive to the needs of those who are harmed. We conclude that elevating the language, narratives, and values of outreach-based community violence intervention and prevention can transform our responses to violence, interrupt cycles of harm, and foster safer communities.

Extreme risk protection orders, race/ethnicity, and equity: Evidence from California

Extreme risk protection orders (ERPOs) provide a civil mechanism to temporarily remove firearm access from individuals at high risk of harming themselves or others. Evidence and theory suggest that ERPOs can prevent firearm-related harm, but the policy's impact on racial/ethnic equity is largely unknown. To examine potential inequities by race/ethnicity in public perceptions and use of California's ERPO law, we drew on two complementary data sources: 1) a 2020 state-representative survey of California adults, and 2) ERPO court documents for the first 3 years of policy implementation (2016-2018). Majorities (54-89%) of all racial/ethnic groups reported that ERPOs are at least sometimes appropriate, and 64-94% were willing to ask a judge for an ERPO for a family member. However, Black and Hispanic/Latinx survey participants less often perceived ERPOs as appropriate and were less willing to serve as petitioners, with Black participants citing lack of knowledge about ERPOs and not trusting the system to be fair as their top reasons for unwillingness. Similarly, review of ERPO court documents revealed that no family or household members served as petitioners for Black and Hispanic/Latinx ERPO respondents. Additionally, Black respondents were the least likely to have documented access to a firearm and legal representation in court. Racial/ethnic equity in ERPO use may be improved by reducing barriers to petitioning, incorporating non-law enforcement intervention professionals like behavioral health specialists into the ERPO process, providing legal assistance to respondents and petitioners, and investing in the social safety net.

Association between race, shooting hot spots, and the surge in gun violence during the COVID-19 pandemic in Philadelphia, New York and Los Angeles

Gun violence rates increased in U.S. cities in 2020 and into 2021. Gun violence rates in U.S. cities is typically concentrated in racially segregated neighborhoods with higher poverty levels. However, poverty levels and demographics alone do not explain the high concentration of violence or its relative change over time. In this paper, we examine the extent to which the increase in shooting victimization in Philadelphia, New York, and Los Angeles during the 2020-2021 pandemic was concentrated in gun violence hot spots, and how the increase impacted race and ethnic disparities in shooting victimization rates. We find that 36% (Philadelphia), 47% (New York), and 55% (Los Angeles) of the increase in shootings observed during the period 2020-2021 occurred in the top decile of census block groups, by aggregate number of shootings, and that the race/ethnicity of victims in these gun violence hot spots were disproportionately Black and Hispanic. We discuss the implications of these findings as they relate to racial disparities in victimization and place-based efforts to reduce gun violence.

Neighborhood segregation, tree cover and firearm violence in 6 U.S. cities, 2015-2020

Neighborhood segregation by race and income is a structural determinant of firearm violence. Addressing green space deficits in segregated neighborhoods is a promising prevention strategy. This study assessed the potential for reducing firearm violence disparities by increasing access to tree cover. Units of analysis were census tracts in six U.S. cities (Baltimore, MD; Philadelphia, PA; Richmond, VA; Syracuse, NY; Washington, DC; Wilmington, DE). We measured segregation using the index of concentration at the extremes (ICE) for race-income. We calculated proportion tree cover based on 2013-2014 imagery. Outcomes were 2015-2020 fatal and non-fatal shootings from the Gun Violence Archive. We modeled firearm violence as a function of ICE, tree cover, and covariates representing the social and built environment. Next, we simulated possible effects of "tree equity" programs, i.e., raising tract-level tree cover to a specified baseline level. In our fully-adjusted model, higher privilege on the ICE measure (1 standard deviation, SD) was associated with a 42% reduction in shootings (incidence rate ratio (IRR) = 0.58, 95% CI [0.54 0.62], p < 0.001). A 1-SD increase in tree cover was associated with a 9% reduction (IRR = 0.91, 95% CI [0.86, 0.97], p < 0.01). Simulated achievement of 40% baseline tree cover was associated with reductions in firearm violence, with the largest reductions in highly-deprived neighborhoods. Advancing tree equity would not disrupt the fundamental causes of racial disparities in firearm violence exposure, but may have the potential to help mitigate those disparities.

Disparities in traumatic brain injury-related deaths-United States, 2020

INTRODUCTION

Traumatic brain injury (TBI) affects how the brain functions and remains a prominent cause of death in the United States. Although preventable, anyone can experience a TBI and epidemiological research suggests some groups have worse health outcomes following the injury.

METHODS

We analyzed 2020 multiple-cause-of-death data from the National Vital Statistics System to describe TBI mortality by geography, sociodemographic characteristics, mechanism of injury (MOI), and injury intent. Deaths were included if they listed an injury International Classification of Diseases, Tenth Revision (ICD-10) underlying cause of death code and a TBI-related ICD-10 code in one of the multiple-cause-of-death fields.

RESULTS

During 2020, 64,362 TBI-related deaths occurred and age-adjusted rates, per 100,000 population, were highest among persons residing in the South (20.2). Older adults (≥75) displayed the highest number and rate of TBI-related deaths compared with other age groups and unintentional falls and suicide were the leading external causes among this older age group. The age-adjusted rate of TBI-related deaths in males was more than three times the rate of females (28.3 versus 8.4, respectively); further, males displayed higher numbers and age-adjusted rates compared with females for all the principal MOIs that contributed to a TBI-related death. American Indian or Alaska Native, Non-Hispanic (AI/AN) persons had the highest age-adjusted rate (29.0) of TBI-related deaths when compared with other racial and ethnic groups. Suicide was the leading external cause of injury contributing to a TBI-related death among AI/AN persons.

PRACTICAL APPLICATION

Prevention efforts targeting older adult falls and suicide are warranted to reduce disparities in TBI mortality among older adults and AI/AN persons. Effective strategies are described in CDC's Stopping Elderly Accidents, Deaths, & Injuries (STEADI) initiative to reduce older adult falls and CDC's Preventing Suicide: A Technical Package of Policy, Programs, and Practices for the best available evidence in suicide prevention.

Racial Disparities in Child Exposure to Firearm Violence Before and During COVID-19

INTRODUCTION

Childhood exposure to neighborhood firearm violence adversely affects mental and physical health across the life course. Study objectives were to (1) quantify racial disparities in these exposures across the U.S. and (2) assess changes during the COVID-19 pandemic, when firearm violence increased.

METHODS

The study used counts of children aged 5-17 years, disaggregated by U.S. Census racial category, for every census tract (N=73,056). Neighborhood firearm violence was the number of fatal shootings per census tract, based on 2015-2021 Gun Violence Archive data. Quasi-Poisson regressions were used to estimate baseline disparities and COVID-19‒related changes and examined differences across geographic regions.

RESULTS

Prepandemic exposure was lowest among White children and highest among Black children, who experienced 4.44 times more neighborhood firearm violence exposure (95% CI=4.33, 4.56, p<0.001) than White children. The pandemic increased exposure by 27% in the lowest risk group (i.e., White children; 95% CI=20%, 34%, p<0.001), but pandemic effects were even greater for children in nearly all non-White categories. Baseline violence levels and racial disparities varied considerably by region, with the highest levels in the South and the largest magnitude disparities observed in the Northeast and Midwest.

CONCLUSIONS

Large-scale racial disparities exist in child exposure to neighborhood firearm violence, and these disparities grew during the pandemic. Equitable access to trauma-informed programs, community-based prevention, and structural reforms are urgently needed.

Preventing Urban Firearm Homicides during COVID-19: Preliminary Results from Three Cities with the Advance Peace Program

The years 2020-2021 during the COVID-19 pandemic witnessed increases in firearm violence in many cities across the USA. We present data from Sacramento, Stockton, and Richmond, California that suggests firearm homicides during the pandemic did not increase in all communities or disproportionately burden the African American community. More specifically, we found that in these cities, there was a 5-52% decrease in gun homicides during the 2020/2021 period compared to the 2018/2019 period for neighborhoods with a gun violence prevention program operating there. We also found a 24-83% reduction in gun homicides in census tracts with > 20% Black populations in Sacramento and Stockton during the 2020/2021 period compared to the 2018/2019 period. In two cities, there was a 15-42% decrease in the number of African American men under 35 years old that were victims of a gun homicide in 2021 compared to 2018. We also found that the gun violence program operating in these cities called Advance Peace interrupted 202 street-level conflicts where guns were present across the three cities in 2020/2021 compared to 178 of the same conflicts in 2018/2019. These interruptions likely saved hundreds of lives and we estimate contributed to between US $65 and $494 million in savings. Advance Peace is a program that engages those at the center of gun violence, frequently young, Black men under 35 years old, and offers them the Peacemaker Fellowship, an intensive, 18-month program of 24/7 mentorship, social services, and life opportunities. The program is delivered by community resident "credible messengers," who conduct the mentorship and interrupt conflicts in the streets. While these findings are descriptive and preliminary, we know of no other program that was in operation before and during the pandemic in each of these cities that engaged the hard-to-reach but highly influential population at the center of gun violence.

Vital Signs: Changes in Firearm Homicide and Suicide Rates - United States, 2019-2020

INTRODUCTION

The majority of homicides (79%) and suicides (53%) in the United States involved a firearm in 2020. High firearm homicide and suicide rates and corresponding inequities by race and ethnicity and poverty level represent important public health concerns. This study examined changes in firearm homicide and firearm suicide rates coinciding with the emergence of the COVID-19 pandemic in 2020.

METHODS

National vital statistics and population data were integrated with urbanization and poverty measures at the county level. Population-based firearm homicide and suicide rates were examined by age, sex, race and ethnicity, geographic area, level of urbanization, and level of poverty.

RESULTS

From 2019 to 2020, the overall firearm homicide rate increased 34.6%, from 4.6 to 6.1 per 100,000 persons. The largest increases occurred among non-Hispanic Black or African American males aged 10-44 years and non-Hispanic American Indian or Alaska Native (AI/AN) males aged 25-44 years. Rates of firearm homicide were lowest and increased least at the lowest poverty level and were higher and showed larger increases at higher poverty levels. The overall firearm suicide rate remained relatively unchanged from 2019 to 2020 (7.9 to 8.1); however, in some populations, including AI/AN males aged 10-44 years, rates did increase.

CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE

During the COVID-19 pandemic, the firearm homicide rate in the United States reached its highest level since 1994, with substantial increases among several population subgroups. These increases have widened disparities in rates by race and ethnicity and poverty level. Several increases in firearm suicide rates were also observed. Implementation of comprehensive strategies employing proven approaches that address underlying economic, physical, and social conditions contributing to the risks for violence and suicide is urgently needed to reduce these rates and disparities.

Crime and deviance during the COVID-19 pandemic

The COVID-19 pandemic has fundamentally changed the world and inevitably influenced people's behaviors including the likelihood of crime and deviance. Emerging empirical evidence suggests a decline in certain crimes (e.g., theft, robbery, and assault) but also proliferation of different violent behaviors and cybercriminal activity during the pandemic. To explain those trends, we draw on existent theories and elaborate on how crime and violence have been affected by the changes in people's daily routines and accumulated stressful conditions. However, as recent crime trends appear to be largely inconsistent and vary across social groups and contexts, we argue that social scientists need to pay particular attention to the differential experiences related to crime and violence during this global crisis. Specifically, because of the disproportionate experience of violence by vulnerable groups including minorities and women as well as the unique cross-national variations in deviance, more nuanced approaches to understanding causes of crime are warranted. We also discuss the limitations of present research and provide recommendations for the development of comparative and multi-disciplinary studies on criminal and deviant behaviors that are influenced by human crisis situations.

Changing epidemiology of firearm injury: a cohort study of non-fatal firearm victimisation before and during the COVID-19 pandemic, Indianapolis, Indiana

OBJECTIVE

To examine victimisation rates, geographic patterns and neighbourhood characteristics associated with non-fatal firearm injury rates before and during the COVID-19 pandemic.

DESIGN

A retrospective cohort study.

SETTING

City of Indianapolis, Indiana, USA, 1 January 2017-30 June 2021.

PARTICIPANTS

Intentional non-fatal firearm injury victims from Indianapolis Metropolitan Police Department records. The study included information on 2578 non-fatal firearm injury victims between ages 0 and 77 years. Of these victims, 82.5% were male and 77.4% were black.

PRIMARY AND SECONDARY OUTCOME MEASURES

Rates of non-fatal firearm injuries per 100 000 population by victim age, race, sex and incident motive. Prepandemic and peripandemic non-fatal firearm injury rates.

RESULTS

Non-fatal shooting rates increased 8.60%, from 57.0 per 100 000 person-years in prepandemic years to 65.6 per 100 000 person-years during the pandemic (p<0.001). Rates of female victims (15.2 vs 23.8 per 100,000; p<0.001) and older victims (91.3 vs 120.4 per 100,000; p<0.001) increased significantly during the pandemic compared with the prepandemic period. Neighbourhoods with higher levels of structural disadvantage (IRR: 1.157, 95% CI 1.012 to 1.324) and prepandemic firearm injury rates (IRR: 1.001, 95% CI 1.001 to 1.002) was positively associated with higher rates of non-fatal firearm injuries during the pandemic, adjusting for neighbourhood characteristics.

CONCLUSIONS

Non-fatal firearm injuries increased significantly during the COVID-19 pandemic, particularly among female and older victims. Efforts are needed to expand and rethink current firearm prevention efforts that both address the diversification of victimisation and the larger societal trauma of firearm violence.
