Violence across Latin America is an increasingly important factor influencing migration to the US. A particular form of violence that is experienced by many Latinx migrants is extortion. This research analyzes the extortion experiences of Latinx immigrant adults arriving at the US southern border and the impact these experiences have on mental health. We find that on average, participants paid $804 in extortion during their migration. The most common perpetrators of extortion in our study were police followed by immigration officials throughout Latin America. Pregnant participants were less likely to experience extortion and adults traveling with children were more likely to be extorted. Participants who were extorted for money reported significantly greater severity of post-traumatic stress disorder (PTSD) symptoms compared to those who were not extorted. This research is the first of its kind to analyze extortion experiences among Latinx immigrants to the US, quantifying the prevalence, amounts paid, countries where extortion occurs, and perpetrators of extortion. In addition, extortion experiences are associated with negative effects on the mental health of newly arrived Latinx immigrants to the US. Based upon these findings, we recommend that extortion should be considered a significant stressor in the migrant experience, particularly for those adults traveling with children.

Background: Incorporating post-discharge data into trauma registries would allow for better research on patient outcomes, including disparities in outcomes. This pilot study tested a follow-up data collection process to be incorporated into existing trauma care systems, prioritizing low-cost automated response modalities.

Methods: This investigation was part of a larger study that consisted of two protocols with two distinct cohorts of participants who experienced traumatic injury. Participants in both protocols were asked to provide phone, email, text, and mail contact information to complete follow-up surveys assessing patient-reported outcomes six months after injury. To increase follow-up response rates between protocol 1 and protocol 2, the study team modified the contact procedures for the protocol 2 cohort. Frequency distributions were utilized to report the frequency of follow-up response modalities and overall response rates in both protocols.

Results: A total of 178 individuals responded to the 6-month follow-up survey: 88 in protocol 1 and 90 in protocol 2. After implementing new follow-up contact procedures in protocol 2 that relied more heavily on the use of automated modalities (e.g., email and text messages), the response rate increased by 17.9 percentage points. The primary response modality shifted from phone (72.7%) in protocol 1 to the combination of email (47.8%) and text (14.4%) in protocol 2.

Conclusions: Results from this investigation suggest that follow-up data can feasibly be collected from trauma patients. Use of automated follow-up methods holds promise to expand longitudinal data in the national trauma registry and broaden the understanding of disparities in patient experiences.

Background: Data regarding rural youths' experience with firearms, including safety training, is highly limited despite their frequent presence in homes. Our objective was to investigate rural adolescents' use of firearms and whether they had received formal firearm training.

Methods: A convenience sample of 2021 National FFA (formerly Future Farmers of America) Convention & Expo attendees were given an anonymous survey at the University of Iowa Stead Family Children's Hospital injury prevention booth. The survey explored their use of rifles/shotguns and handguns and whether they had completed a certified firearm safety course. Descriptive and comparative analyses, including multivariable logistic regression analyses, were performed on compiled data.

Results: 3206 adolescents ages 13-18 years participated with 45% reporting they lived on a farm or ranch. The vast majority of participants (85%) had fired a rifle/shotgun; 43% reported firing them > 100 times. Of those that had fired rifles/shotguns, 41% had done so before 9 years old. Most had also fired a handgun (69%), with 23% having fired handguns > 100 times. Of those that had fired handguns, 44% had done so before 11 years. Average age for first firing rifles/shotguns was 9.5 (SD 3.1) years, and 11.1 (SD 3.0) years for handguns. Males, non-Hispanic Whites, and those living on farms or in the country had significantly greater percentages who had fired a rifle/shotgun or a handgun. Significant differences were also seen by U.S. census region. Over half (64%) reported having gone hunting. Of those that had used a firearm, 67% had completed a firearm safety training course. Overall, 23% were/had been members of a school or club shooting team and of these, 87% had taken a safety course.

Conclusions: Most FFA member participants had fired both rifles/shotguns and handguns, many at very young ages. Significant differences in firearm use were noted by demographic factors including the home setting (i.e., farms and ranches) and their U.S. census region. Nearly one-third of adolescent firearm users had not received formal safety training. Promoting firearm safety should include advising families on when it is developmentally appropriate to introduce youth to firearms and on the importance of firearm safety training.

Background: Firearm purchasing records offer a potentially important administrative data source to identify individuals at elevated risk of perpetrating firearm violence. In this study, we describe individual, firearm, and transaction characteristics of purchasers in California who were arrested for a firearm-related violent crime (FRV) as compared to the general population of registered purchasers in the state.

Methods: Relying on a dataset of all individuals with transaction records in California (1996-2021), linked to criminal records (1980-2021), we enrolled a cohort of individuals for whom we could capture the legal firearm purchase history. We identified those arrested for FRV post purchase, and using incidence density sampling, gender-matched cases to ten purchasers (controls) who remained "at risk" at the time the case was arrested. We focused on the purchase closest in time prior to the arrest ("index" purchase). We implemented conditional logistic regression and included models with controls for individual- and community-level demographics, as well as interactions between firearm and purchasing characteristics and criminal history.

Results: The cohort included 1,212,144 individuals, of whom 6153 were arrested for FRV (0.5%). Cases were matched to 61,530 controls to form the study sample. The largest risk factor was a prior criminal history: purchasers had 5.84 times the risk of FRV if they had a prior arrest within three years of the index purchase (CI 5.44-6.27). Several transaction and firearm characteristics were also associated with FRV. For example, risk increased if the firearm was redeemed at a pawn shop (aIRR: 1.37, CI 1.05-1.77) and decreased if the transaction was a registered private party transfer (vs. retail purchase) (aIRR: 0.83, CI 0.76-0.90) or the firearm was a bolt action firearm (vs. semi-automatic) (aIRR: 0.64, CI 0.51-0.79). In the interaction models, most of the purchase and firearm features only remained significant among those with no criminal history.

Conclusions: Given limited data on firearm transactions, there has been little research on whether the type of firearm an individual purchases or the nature of the purchase might serve as indicators of risk for FRV. We found several transaction and firearm features were associated with risk of FRV. Notably, these features provided little evidence of additional risk for those with a prior criminal record.

Background: Firearm suicide is a leading cause of death in the United States. Suicide prevention experts have advocated for upstream interventions that can be implemented prior to the development of suicidal thoughts, particularly those that focus on lethal means safety (LMS; e.g., increasing secure firearm storage). To reach firearm owners with LMS messaging, researchers have developed suicide prevention training content which can be incorporated into firearm training courses. However, no study to date has evaluated impact of such training on firearm course students' subsequent knowledge, attitudes, and openness related to secure firearm storage. Thus, the current study sought to examine both the feasibility and acceptability of a LMS-focused suicide prevention training module among firearm course students, as well as the impact of this module on students' secure firearm storage-related knowledge, attitudes, and openness.

Methods: Firearm instructors (N = 6) and students in firearm classes (N = 83) were recruited to participate. Students were invited to complete voluntary, anonymous pre- and post-surveys during courses they attended that were led by these instructors. Instructors and students were also invited to complete a brief qualitative interview.

Results: Results indicated that firearm instructors and students in firearm courses found the module feasible and acceptable. Additionally, students' knowledge about the relationship between firearms and suicide, openness to changing firearm storage practices, and endorsement of the importance of discussing firearms and suicide with fellow firearm owners, as well as willingness and confidence to do so, all significantly increased after viewing the module.

Conclusions: These findings provide strong support for the use of such culturally competent LMS messaging as upstream suicide prevention in settings such as concealed carry courses.

Background: Surveys have found concerningly high levels of agreement that the United States will experience civil war soon. This study assesses variation in expectation of and perceived need for civil war with respondent sociopolitical characteristics, beliefs, firearm ownership, and willingness to engage in political violence.

Methods: Findings are from Wave 2 of a nationally representative annual longitudinal survey of members of the Ipsos KnowledgePanel, conducted May 18-June 8, 2023. All respondents to 2022's Wave 1 who remained in KnowledgePanel were invited to participate. Outcomes are expressed as weighted proportions and adjusted prevalence differences, with p-values adjusted for the false discovery rate and reported as q-values.

Results: The completion rate was 84.2%; there were 9385 respondents. After weighting, half the sample was female (50.7%, 95% CI 49.4%, 52.1%); the weighted mean (± standard deviation) age was 48.5 (25.9) years. Approximately 1 respondent in 20 (5.7%, 95% CI 5.1%, 6.4%) agreed strongly or very strongly that "in the next few years, there will be civil war in the United States." About 1 in 25 (3.8%, 95% CI 3.2%, 4.4%), and nearly 40% (38.4%, 95% CI 32.3%, 44.5%) of those who strongly or very strongly agreed that civil war was coming, also agreed strongly or very strongly that "the United States needs a civil war to set things right." Expectation of and perceived need for civil war were higher among subsets of respondents who in Wave 1 were more willing than others to commit political violence, including MAGA Republicans, persons in strong agreement with racist beliefs or statements of the potential need for violence to effect social change, persons who strongly approved of specified extreme right-wing political organizations and movements, firearm owners who purchased firearms in 2020 or later, and firearm owners who carried firearms in public all or nearly all the time.

Conclusions: In 2023, the expectation that civil war was likely and the belief that it was needed were uncommon but were higher among subsets of the population that had previously been associated with greater willingness to commit political violence. These findings can help guide prevention efforts.

Background: Handgun purchaser licensing (HPL) laws mandate individuals to obtain a license from law enforcement before buying a firearm. Research indicates these laws effectively reduce various forms of fatal firearm violence, including homicides, suicides, and mass shootings. Our study sought to assess the impact of HPL laws on non-fatal firearm violence.

Methods: Utilizing the augmented synthetic control method (ASCM), we estimated the average treatment effect on the treated (ATT) resulting from a full repeal of an HPL law in Missouri (2007), a partial repeal in Michigan (2012), and an adoption on HPL law in Maryland (2013) on firearm injury hospitalizations. We utilized RAND's healthcare cost and utilization project-based dataset from 2000 to 2016 for our outcome variable. We conducted in-time placebo testing and leave-one-out donor pool testing as sensitivity analyses.

Results: Maryland's adoption was associated with a statistically significant 32.3% reduction in firearm-related injury hospitalization (FIH) rates (ATT = - 0.497, standard error (SE) = 0.123); Missouri's repeal was associated with a statistically significant 35.7% increase in FIH rates (ASCM = 0.456, SE = 0.155); and Michigan's partial repeal showed no statistically significant associations with FIH rates (ATT = - 0.074, SE = 0.129). Sensitivity analyses confirm the robustness of the estimated HPL effects.

Discussion: HPL laws appear to be protective against hospitalizations for nonfatal firearm injuries. These findings align with prior research indicating that HPL laws are effective in reducing fatal firearm violence. States without such licensing systems ought to consider these robust policies as a means to address firearm violence.

Background: Describe trends in perpetrator characteristics and firearm use in pediatric homicides across the United States.

Methods: Multiply-imputed data from the Federal Bureau of Investigation's 1976-2020 Supplementary Homicide Reports were used to estimate perpetrator characteristics (sex, age, and relationship to victim) and firearm use in pediatric homicides. Descriptive analyses were stratified by victim age group, sex, race, and five-year time periods.

Results: Family members were the most common perpetrator of infant and toddler (ages 0-4) and child (ages 5-12) homicides, whereas acquaintances accounted for the majority of adolescent (ages 13-19) homicides. Perpetrator characteristics vary across victim sex and race, particularly among adolescents. Despite overall stability, there were changes in perpetrator characteristics from 1976 to 2020. There was a sustained increase in the proportion of homicides committed with a firearm. In 2016-2020, the proportion of firearm-involved homicides was an all-time high for infant and toddler (14.8%), child (53.1%), and adolescent victims (88.5%).

Conclusions: Policy interventions that improve family stability and well-being may be most effective at preventing infant, toddler, and child homicides, whereas programs that target peer and community relationships, as well as policies that focus on firearm access, may be more crucial for preventing adolescent homicides.

Background: Administrative healthcare databases, such as Medicare, are increasingly used to identify groups at risk of a crash. However, they only contain information on crash-related injuries, not all crashes. If the driver characteristics associated with crash and crash-related injury differ, conflating the two may result in ineffective or imprecise policy interventions.

Methods: We linked 10 years (2008-2017) of Medicare claims to New Jersey police crash reports to compare the demographics, clinical diagnoses, and prescription drug dispensings for crash-involved drivers ≥ 68 years with a police-reported crash to those with a claim for a crash-related injury. We calculated standardized mean differences to compare characteristics between groups.

Results: Crash-involved drivers with a Medicare claim for an injury were more likely than those with a police-reported crash to be female (62.4% vs. 51.8%, standardized mean difference [SMD] = 0.30), had more clinical diagnoses including Alzheimer's disease and related dementias (13.0% vs. 9.2%, SMD = 0.20) and rheumatoid arthritis/osteoarthritis (69.5% vs 61.4%, SMD = 0.20), and a higher rate of dispensing for opioids (33.8% vs 27.6%, SMD = 0.18) and antiepileptics (12.9% vs 9.6%, SMD = 0.14) prior to the crash. Despite documented inconsistencies in coding practices, findings were robust when restricted to claims indicating the injured party was the driver or was left unspecified.

Conclusions: To identify effective mechanisms for reducing morbidity and mortality from crashes, researchers should consider augmenting administrative datasets with information from police crash reports, and vice versa. When those data are not available, we caution researchers and policymakers against the tendency to conflate crash and crash-related injury when interpreting their findings.

Background: Injurious falls represent a significant public health burden. Research and policies have primarily focused on falls occurring indoors despite evidence that outdoor falls account for 47-58% of all falls requiring some medical attention. This study described the clinical trauma severity of indoor versus outdoor injurious falls requiring Emergency Medical Services (EMS) response.

Methods: Using the 2019 National Emergency Medical Services Information System (NEMSIS) dataset, we identified the location of patients injured from falls that required EMS response. We classified injury severity using (1) the Revised Trauma Score for Triage (T-RTS): ≤ 11 indicated the need for transport to a Trauma Center; (2) Glasgow Coma Scale (GCS): ≤ 8 and 9-12 indicated severe and moderate neurologic injury; and (3) patient clinical acuity by EMS: Dead, Critical, Emergent, Low.

Results: Of 1,854,909 encounters for patients with injurious falls, the vast majority occurred indoors (n = 1,596,860) compared to outdoors (n = 152,994). For patients who fell indoors vs outdoors on streets or sidewalks, the proportions were comparable for moderate or severe GCS scores (3.0% vs 3.9%), T-RTS scores indicating need for transport to a Trauma Center (5.2% vs 5.9%) and EMS acuity rated as Emergent or Critical (27.7% vs 27.1%). Injurious falls were more severe among male patients compared to females and males injured by falling on streets or sidewalks had higher percentages for moderate or severe GCS scores (5.2% vs 1.9%) and T-RTS scores indicating the need for transport to a Trauma Center (7.3% vs 3.9%) compared to falling indoors. Young and middle-aged patients who fell on streets or sidewalks had higher proportions for a T-RTS score indicating the need for Trauma Center care compared to those in this subgroup who fell indoors. Yet older patients injured by falling indoors were more likely to have a T-RTS score indicating the need for transport to a Trauma Center than older patients who fell on streets or sidewalks.

Conclusions: There was a similar proportion of patients with severe injurious falls that occurred indoors and outdoors on streets or sidewalks. These findings suggest the need to determine outdoor environmental risks for outdoor falls to support location-specific interventions.
