School Shootings in the United States: 1997-2022.

OBJECTIVES: Gun violence in the United States is a public health crisis. In 2019, gun injury became the leading cause of death among children aged birth to 19 years. Moreover, the United States has had 57 times as many school shootings as all other major industrialized nations combined. The purpose of this study was to understand the frequency of school-related gun violence across a quarter century, considering both school shootings and school mass shootings. METHODS: We drew on 2 publicly available datasets whose data allowed us to tabulate the frequency of school shootings and school mass shootings. The databases contain complementary data that provide a longitudinal, comprehensive view of school-related gun violence over the past quarter century. RESULTS: Across the 1997-1998 to 2021-2022 school years, there were 1453 school shootings. The most recent 5 school years reflected a substantially higher number of school shootings than the prior 20 years. In contrast, US school mass shootings have not increased, although school mass shootings have become more deadly. CONCLUSIONS: School shootings have risen in frequency in the recent 25 years and are now at their highest recorded levels. School mass shootings, although not necessarily increasing in frequency, have become more deadly. This leads to detrimental outcomes for all the nation's youth, not just those who experience school-related gun violence firsthand. School-based interventions can be used to address this public health crisis, and effective approaches such as Multi-Tiered Systems of Supports and services should be used in support of students' mental health and academic and behavioral needs.

National Burden of Injury and Deaths From Shootings by Police in the United States, 2015‒2020.

Objectives. To describe all-outcome injurious shootings by police and compare characteristics of fatal versus nonfatal injurious shootings nationally. Methods. From July 2021 to April 2023, we manually reviewed publicly available records on all 2015-2020 injurious shootings by US police, identified from Gun Violence Archive. We estimated injury frequency, case fatality rates, and relative odds of death by incident and victim characteristics. Results. A total of 1769 people were injured annually in shootings by police, 55% fatally. When a shooting injury occurred, odds of fatality were 46% higher following dispatched responses than police-initiated responses. Injuries associated with physically threatening or threat-making behaviors, behavioral health needs, and well-being checks were most frequently fatal. Relative to White victims, Black victims were overrepresented but had 35% lower odds of fatal injury when shot. Conclusions. This first multiyear, nationwide analysis of injurious shootings by US police suggests that injury disparities are underestimated by fatal shootings alone. Nonpolicing responses to social needs may prevent future injuries. Public Health Implications. We call for enhanced reporting systems, comprehensive evaluation of emerging reforms, and targeted investment in social services for equitable injury prevention.

Firearm Access and Gun Violence Exposure Among American Indian or Alaska Native and Black Adults.

Importance: American Indian or Alaska Native and Black adults experience elevated rates of firearm injury and death, but both groups are severely underrepresented in research on firearm exposure and behaviors. Objective: To explore geodemographic differences in firearm behaviors and violence exposure among American Indian or Alaska Native and Black adults in the US. Design, Setting, and Participants: In this survey study, nationally representative samples of American Indian or Alaska Native and/or Black adults recruited from KnowledgePanel were surveyed cross-sectionally. Surveys were administered online between April 12 and May 4, 2023. Main Outcomes and Measures: Firearm access, storage, and carrying behaviors and lifetime firearm violence exposure were the primary outcomes. Demographic factors such as age, geographic location, and political affiliation were considered. Data were weighted to geodemographic distributions from the US Census Bureau's 2022 Current Population Survey. Results: Of 3542 participants, 527 (14.9%) were American Indian or Alaska Native (280 [53.1%] female) and 3015 (85.1%) were Black (1646 [54.6%] female). Both groups exhibited high firearm access rates (American Indian or Alaska Native adults: 238 [45.4%; 95% CI, 39.4%-51.7%]; Black adults: 909 [30.4%; 95% CI, 28.0%-32.9%]), predominantly owning handguns for home protection. The groups demonstrated similar firearm storage patterns, and a substantial proportion endorsed always or almost always carrying firearms outside the home (American Indian or Alaska Native adults: 18.9%; Black adults: 15.2%). Self-protection was a common reason for carrying a firearm (American Indian or Alaska Native adults: 104 [84.9%; 95% CI, 74.1%-91.7%]; Black adults: 350 [88.3%; 95% CI, 82.3%-92.4%]), and a minority of participants cited lack of faith in the police (American Indian or Alaska Native adults: 19 [15.2%; 95% CI, 8.2%-26.7%]; Black adults: 61 [15.4%; 95% CI, 10.3%-21.2%]), indicating potential shifts in public safety dynamics. Conclusions and Relevance: In this survey study of American Indian or Alaska Native and Black US adults, a substantial percentage of both groups reported living in homes with firearms, storing firearms loaded and unlocked, frequently carrying firearms outside the home, and having been exposed directly and indirectly to gun violence. These findings underscore the need for nuanced public health campaigns and policies and highlight challenges for law enforcement in contexts of racial disparities and changing legal frameworks.

Gun Violence Exposure and Suicide Among Black Adults.

Importance: Black individuals are disproportionately exposed to gun violence in the US. Suicide rates among Black US individuals have increased in recent years. Objective: To evaluate whether gun violence exposures (GVEs) are associated with suicidal ideation and behaviors among Black adults. Design, Setting, and Participants: This cross-sectional study used survey data collected from a nationally representative sample of self-identified Black or African American (hereafter, Black) adults in the US from April 12, 2023, through May 4, 2023. Exposures: Ever being shot, being threatened with a gun, knowing someone who has been shot, and witnessing or hearing about a shooting. Main Outcomes and Measures: Outcome variables were derived from the Self-Injurious Thoughts and Behaviors Interview, including suicidal ideation, suicide attempt preparation, and suicide attempt. A subsample of those exhibiting suicidal ideation was used to assess for suicidal behaviors. Results: The study sample included 3015 Black adults (1646 [55%] female; mean [SD] age, 46.34 [0.44] years [range, 18-94 years]). Most respondents were exposed to at least 1 type of gun violence (1693 [56%]), and 300 (12%) were exposed to at least 3 types of gun violence. Being threatened with a gun (odds ratio [OR], 1.44; 95% CI, 1.01-2.05) or knowing someone who has been shot (OR, 1.44; 95% CI, 1.05-1.97) was associated with reporting lifetime suicidal ideation. Being shot was associated with reporting ever planning a suicide (OR, 3.73; 95% CI, 1.10-12.64). Being threatened (OR, 2.41; 95% CI, 2.41-5.09) or knowing someone who has been shot (OR, 2.86; 95% CI, 1.42-5.74) was associated with reporting lifetime suicide attempts. Cumulative GVE was associated with reporting lifetime suicidal ideation (1 type: OR, 1.69 [95% CI, 1.19-2.39]; 2 types: OR, 1.69 [95% CI, 1.17-2.44]; ≥3 types: OR, 2.27 [95% CI, 1.48-3.48]), suicide attempt preparation (≥3 types; OR, 2.37; 95% CI, 2.37-5.63), and attempting suicide (2 types: OR, 4.78 [95% CI, 1.80-12.71]; ≥3 types: OR, 4.01 [95% CI, 1.41-11.44]). Conclusions and Relevance: In this cross-sectional study, GVE among Black adults in the US was significantly associated with lifetime suicidal ideation and behavior. Public health efforts to substantially reduce interpersonal gun violence may yield additional benefits by decreasing suicide among Black individuals in the US.

An Academic-Community Partnership to Address Gun Violence in the Roseland Neighborhood of Chicago.

BACKGROUND AND OBJECTIVES: Gun violence is the leading cause of death for youth. This study examined an academic-community partnership to address gun violence through a strength-based approach called Asset-Based Community Development. METHODS: We used a case study design. Participants were Black youth who encounter frequent gun violence (average age = 16.7 years; 72% male). Our partnership involved survey development/completion and semistructured discussions. We also interviewed community stakeholders to collect data on local assets. We interpreted data through a communitywide forum to guide social action to address gun violence. RESULTS: The majority of youth (76%) witnessed neighborhood violence in the last year. The top youth concerns related to gun violence included poverty, guns, and gangs. Community stakeholders saw local people and local organizations as primary community assets. A community forum to interpret these data led to social action in the form of an environmental strategy-cleaning up an unused commercial building for the development of a youth tech center. The majority of youth participants (89.5%) agreed or strongly agreed that they had a voice in the research process. CONCLUSION: Participatory research that takes an asset-based approach can enable relevant inquiry that engages youth and guides social action to address gun violence.

Urban Teen Perspectives on Gun Violence: a Mixed Methods Study.

We aimed to explore perspectives of teenagers on their exposure to gun violence (GV), their knowledge and attitudes towards firearm injury prevention (FIP) efforts, and how to counsel them about FIP. Teens from two single-sex Bronx Catholic high schools participated in videoconferencing focus groups. Participants completed an online survey collecting demographic information and Likert-scale scoring of attitudes towards GV. Quantitative data was analyzed with descriptive statistics. Focus group discussions were recorded and transcribed. Using Dedoose, two investigators independently coded data and achieved consensus using content analysis. Six focus groups (3 from each school, n = 28 participants) were held from October-November 2020. A total of 27 participants completed the survey. Eighty-one percent of respondents agreed "Doctors should talk to teens about gun safety." During focus groups, participants reported personal, community, and entertainment media exposure to GV. GV elicited many emotions, including fear and frustration. Teens identified factors contributing to GV that should be addressed, including poverty, racism, and mental illness. Most had not received prior FIP education and desired more information from trusted adults. They preferred discussions over written materials and information given over time. Teens were open to doctors counseling on FIP during healthcare visits and suggested including screening questions on surveys, conversations during healthcare maintenance visits, and classroom talks by physicians. Bronx teens are exposed to and distressed by community GV. They desired more FIP education, including physician counseling during healthcare visits. Next steps are to create and test FIP guidance for adolescents.

Individual and cumulative firearm violence exposure: Implications for sleep among Black and American Indian/Alaska Native adults.

PURPOSE: We investigated the relationship between various forms of firearm violence exposure and sleep problems among nationally representative samples of Black (N = 3015) and American Indian and Alaska Native (AI/AN) (N = 527) adults, focusing on difficulties falling asleep, staying asleep, and waking too early. Survey data were collected in April and May 2023. METHODS: We employed negative binomial regression models to analyze the associations between the different types of firearm violence exposure and sleep problems. We further examined associations between cumulative firearm violence exposure and sleep outcomes. RESULTS: A substantial proportion of Black (59%) and AI/AN (56%) adults reported experiencing some form of firearm violence exposure. Being threatened with a firearm emerged as a consistent factor associated with sleep problems for both racial groups. Witnessing or hearing about shootings was linked to sleep problems in the Black sample, while cumulative firearm violence exposure was associated with all sleep problems in both groups. CONCLUSIONS: Individual and cumulative firearm violence exposure is associated with increased sleep problems among Black and AI/AN adults.

Modeling the Relationship Between Firearm Restrictions, Medicaid Expansion, and Political Partisanship with Pediatric Firearm Mortality Costs.

INTRODUCTION: Firearms are now the leading cause of pediatric mortality in the U.S., but few studies have investigated the economic impact of these deaths. Thus, this study determined whether multiple different gun-related measures, political partisanship and Medicaid expansion were related to the costs of pediatric gun deaths. METHODS: Each states' medical costs, years of potential life lost (YPLL), and value of statistical life (VSL) lost due to pediatric gun deaths were extracted from the WISQARS database from 2015 to 2020. Seven firearm laws or restrictiveness measures (assault weapons bans, child access prevention laws, firearm registration and permit to purchase requirements, safe storage laws, Giffords Law Center ranking, and the number of firearm provisions), the Cook Partisan Voting Index (PVI), and Medicaid expansion status were determined across states. Unadjusted analyses compared each measure and (1) medical costs, (2) VSL, and (3) YPLL for each state. These were repeated using adjusted analyses, controlling for poverty, educational attainment, poor mental health, and race. RESULTS: Of the 9 variables assessed, unadjusted analyses revealed that 8 variables were significantly associated with increased medical costs, all 9 were associated with higher VSL and 8 were associated with higher YPLL due to pediatric firearm-related mortality. Multivariable analyses revealed that 7 variables were associated with medical costs, 7 were associated with VSL and 6 were associated with YPLL. CONCLUSION: States with fewer gun laws and those which have not adopted Medicaid expansion were more likely to experience a higher economic burden due to pediatric gun deaths. Quantifying the costs of these deaths can demonstrate the social toll of gun violence to policymakers and the general public. LEVEL OF EVIDENCE: III.

Need More Reasons to Curb Gun Violence?

This collection of images considers complex ethical, public health, and sociopolitical dimensions of firearm injuries. Since many firearm bullets contain lead, visual parallels are drawn between clinical and public health approaches to managing lead poisoning and efforts to reduce gun violence. Like lead toxicity from paint or water, gun violence and toxicity from retained ballistic fragments can adversely influence health and should be a source of concern to clinicians.

Modification of Firearm Law-Firearm Injury Association by Economic Disadvantage.

INTRODUCTION: Firearm-related injuries in the U.S. have risen 37% since 2015. Understanding how the association between firearm incidents and state-level firearm restrictiveness is modified by community-level distress and economic connectedness (EC) may inform upstream injury prevention efforts. METHODS: A national cross-sectional study of firearm incidents (interpersonal and unintentional firearm events) occurring between 1/2015 and 12/2021 was performed using the Gun Violence Archive. The exposures were community distress (Distressed Communities Index, DCI), EC, and year-state-level firearm restrictiveness. The primary outcome was mean annual urban firearm incidence rate per ZIP Code Tabulation Area. Generalized linear mixed models were fit to evaluate the modification of the firearm law-firearm incident association by DCI and EC. Data analyses took place in 2022. RESULTS: About 266,020 firearm incidents were included. The mean rate was higher with each DCI tertile, with a RR of 3.18 (95% CI: 3.06, 3.30) in high versus low distress communities. Low EC was associated with over 1.8 times greater rate of firearm-related injury. The least restrictive firearm laws were associated with 1.20 times higher risk of firearm incidents (95% CI: 1.12, 1.28). The association between restrictive laws and lower incidence rates was strongest in low and medium distress and high EC communities. CONCLUSIONS: Stricter firearm laws are associated with lower rate of firearm incidents. The magnitude of this association is smallest for communities experiencing the greatest economic disadvantage.

Surveillance of Gun-Related Conversations on Twitter.

Gun violence in the USA is a documented public health crisis. Publicly accessible data from Twitter posts can be used to rapidly capture and describe the public's recent conversations about guns. Because these gun-related conversations change rapidly, it is important to provide regularly updated information on them. Twitter posts containing gun-related terms were obtained from January 1, 2022 to June 30, 2022. To understand topics of gun-related tweets (N = 449,492), topic modeling was performed with Top2Vec. Gun ownership control, concern about gun safety and its impact on children and schools, and the Second Amendment were major areas of the gun-related discourse on Twitter. Several identified topics in this study were a consequence of the study period, including "Discourse on Capitol Riots," and "Wartime and Military Use of Guns," with the latter topic containing conversations about the Russia-Ukraine War. Conversations around the influence of the National Rifle Association (NRA) on gun policies and pro-gun ownership perspectives were also part of the public discourse. The intersection between alcohol, substance use, and gun use was infrequently observed. Findings suggest that gun-related conversations in social media such as Twitter can inform public health researchers.

Characterizing Gun Violence by Time, Day of the Week, Holidays, and Month in 6 US Cities, 2015-2021.

Developing interventions to prevent firearm-related violence and to address its consequences requires an improved understanding of when these violent events are most likely to occur. We explored gunshot events in 6 of the most populated cities in the United States by time of day, day of week, holiday/non-holiday, and month using publicly available datasets. In some of these cities, gunshot events occurred most often at nighttime, on holidays and weekends, and during summer months, with significant interaction effects. There were also time-related changes in characteristics of the victims. Primary prevention efforts aimed at curbing firearm-related violence should consider these differential risks.

Firearm Mortality of Non-Hispanic Black Americans by Law Enforcement, 2011-2020.

Law enforcement officers in the U.S. are more likely to use lethal force against non-Hispanic Black citizens than on their non-Hispanic White counterparts. The purpose of this study was to assess estimates of the national prevalence of fatal firearm violence by law enforcement officers (LEOs) against non-Hispanic Black Americans. The Web-Based Injury Statistics Query and Reporting System (WISQARS) from the Centers for Disease Control and Prevention (CDC) were analyzed using descriptive statistics and joinpoint regression from 2011 to 2020. During the decade (2011-2020) LEOs fatally shot 5,073 citizens and 1,170 were non-Hispanic Black (23%). The vast majority (96%) were males and two-thirds (66%) of those killed were ages 20-39 years. The region with the highest number of LEO fatal shootings was the Western U.S. Firearm deaths of non-Hispanic Blacks were the dominant (82%) method of LEO-induced deaths. Non-Hispanic Black Americans experience LEO firearm-related injuries and deaths at a much higher rate than their non-Hispanic White counterparts. In the context of the racial disparities among people who die following LEO-related gunshot wounds, changes to police training systems and an examination of implicit biases among LEOs should be investigated as the next step in reducing the use of lethal force practices.

"We been dying, and you got me on a call helping you stay alive": Black and Latinx youth organizers' experiences of racism in gun violence prevention organizations.

This study explored Black and Latinx youth organizers' experiences of racism within national gun violence prevention organizing spaces. Interview data were analyzed from 17 Black and/or Latinx youth (Mage = 20.17, 47% women) across the United States who organized against gun violence. The findings identified three forms of racism that Black and Latinx organizers experienced in national organizations: (1) being tokenized for their racial identities and experiences without having real decision making power; (2) feeling a burden to educate their white peers about the structural causes of gun violence and how to improve organizing spaces for other youth of color; and (3) being silenced in their racially conscious organizing efforts to address the structural causes of gun violence in their communities. This research highlights how Black and Latinx youth gun violence prevention organizers contend both with structural racism in their everyday lives and racism in organizing spaces.

Patterns in pro-gun beliefs and weapon carrying behaviors in rural White adolescent.

Weapon carrying among White rural populations is understudied although evidence suggests that rural White boys have high rates of carriage. This study delineated patterns of weapon use and pro-gun beliefs using a latent class analysis on a sample of 32,916 White rural adolescents. Five groups were identified (i.e., Low Gun Risk, Naïve, Social Contagion, Independent, Unsupervised) using pro-gun beliefs, peer risk factors, and weapon carrying items. Multinomial logistic regression analyses revealed that identifying as male, age, housing instability, and victimization consistently differentiated group membership between different classes. These results suggest that rural White adolescents vary in their belief systems about guns and weapon carrying behavior and that this heterogeneity can be differentiated by lived experiences of these adolescents.

Survivor's remorse.

ABSTRACT: In urban, large metropolitan trauma centers, we are accustomed to seeing the most gruesome morbidity and mortality in medicine. By far, the most devastating morbidity and mortality to observe are those inflicted on one human being to another. Gun violence is pervasive in this industrialized country, and it impacts us all. Staff, residents, and faculty in trauma centers bear the brunt of this trauma, second only to the families and communities that suffer the loss of loved ones. This burden is especially heavy for health care workers who share the same ethnic background of those who are disproportionately affected by interpersonal gun violence. Survivors of gun violence exist on a spectrum of chronic illness that ranges in physical and mental morbidity and social disruption in loss of wages and capabilities. This disease not only infects those wounded or killed but also transmits through communities and generations. Urban violence exists because of historic and systematic racism. It continues to persist because racism creates inequities in the quality of education, housing, and investment in urban environments, exacerbated by residential segregation. For two providers, a trainee and a faculty member of African descent, conscious of the determinants that create gun violence, it is overwhelming. We, as health care providers, must tell our stories and the stories of those whose voices are not empowered. We can hope that, by sharing these experiences, we stimulate action and change by raising the moral consciousness of those unaware of the tragedies we witness every day.

Disadvantaged Neighborhoods Continue to Bear the Burden of Gun Violence.

INTRODUCTION: Gun violence is a pervasive and dynamic public health crisis causing substantial burden on communities and healthcare systems in the United States. Risk factor and outcome analyses are crucial to develop effective interventions. The aim of this study was to assess firearm injury in a diverse community setting as it relates to neighborhood socioeconomic disadvantage and changes over time following large-scale local interventions. METHODS: All county residents with firearm injury presenting to a Level 1 Trauma Center from January 2012 to December 2021 were retrospectively reviewed. Area Deprivation Index (ADI) was used to measure neighborhood socioeconomic disadvantage based on a nine-digit zip code at patients' home address. Injuries were also stratified by 5-year time periods, 2012-2016 and 2017-2021. Demographics and clinical data were analyzed including injury severity, hospital course, and discharge location. Data were compared by ADI quintile and between time periods using chi-squared, one-way analysis of variance, and Cochran-Armitage test. RESULTS: A total of 1044 injuries were evaluated. Patients were 93% male with mean age of 29 y (standard deviation 10.2) and were concentrated in the most disadvantaged neighborhoods (74% ADI Q5). Black or African American race was greater in the most disadvantaged ADI groups (76% versus 47%-66%; P <0.001). Percentage of total injuries in the most disadvantaged ADI group rose from 71% to 78% over time (P = 0.006). Mortality occurred in 154 (15%) patients overall, while most (71%) were discharged to home. Mortality declined from 18% to 11% over time (P <0.001). Medicaid utilization rose from 42% to 77% alongside a decrease in self-pay status from 44% to 4% (P <0.001). There were no clinically significant group differences in injury severity or clinical characteristics. CONCLUSIONS: Firearm injury remains concentrated in the most socioeconomically disadvantaged neighborhoods, and this disparity is increasing over time. Medicaid utilization rose and mortality decreased in this population over time. This research presents a method to inform and monitor local gun violence interventions using ADI to address public health equity.
