Firearm-Related Lead Exposure and Child Lead Levels in the United States, 2012-2018.

OBJECTIVE: To determine if firearm ownership is positively related to elevated child lead levels at a state-level, even when accounting for other sources of lead. STUDY DESIGN: For this cross-sectional ecological study, we investigated whether household firearm ownership rates (a proxy for firearm-related lead exposure) was associated with the prevalence of elevated child blood lead levels in 44 US States between 2012 and 2018. To account for potential confounding, we adjusted for other known lead exposures, poverty rate, population density, race, and calendar year. To address missing data, we used multiple imputation by chained equations. RESULTS: Prevalence of elevated child blood lead positively correlated with household firearm ownership and established predictors of lead exposure. In fully adjusted negative binomial regression models, child blood lead was positively associated with household firearm ownership and older housing; each IQR (14%) increase in household firearm ownership rate was associated with a 41% higher prevalence of childhood elevated blood lead (prevalence ratio: 1.41, 95% CI: 1.11-1.79). CONCLUSION: These data provide state-level evidence that firearms may be an important source of child lead exposure. More research is needed to substantiate this relationship and identify modifiable pathways of exposure at the individual level.

Reducing fall injuries with better data.

BACKGROUND: Fall deaths in the USA almost tripled in the twenty-first century. While various interventions have been effective in reducing fall deaths, they have failed to make a substantial impact at a population level. MAIN BODY: An overarching factor that has been relatively neglected in fall injury prevention is the need for more and better data. We need better data on the causes and circumstances of older adult fall deaths. While there are excellent national surveillance systems on the circumstances of other injury deaths (e.g., motor vehicle crashes, suicides, and homicides), such a system is lacking for fall deaths. These other data systems have been instrumental in indicating and evaluating policies that will reduce injury. It is also important to provide consumers with better information concerning the many products that affect the likelihood of fall injury (e.g., flooring, hip protectors, footwear). Automotive buyers are provided with relevant up-to-date make-model safety information from crash tests and real-world performance. Such information not only helps protect buyers from purchasing dangerous products, but it provides producers with the incentive to make ever safer products over time. CONCLUSION: We believe that creation of a national surveillance system on the circumstances of fall deaths, and increased testing/certifying of fall-related products, are two steps that would help create the conditions for continuous reductions in fall fatalities. Fall prevention should apply some of the same basic strategies that have proved effective in addressing other injuries.

Projected Health Outcomes Associated With 3 US Supreme Court Decisions in 2022 on COVID-19 Workplace Protections, Handgun-Carry Restrictions, and Abortion Rights.

Importance: Several recent US Supreme Court rulings have drawn criticism from the medical community, but their health consequences have not been quantitatively evaluated. Objective: To model health outcomes associated with 3 Supreme Court rulings in 2022 that invalidated workplace COVID-19 vaccine or mask-and-test requirements, voided state handgun-carry restrictions, and revoked the constitutional right to abortion. Design, Setting, and Participants: This decision analytical modeling study estimated outcomes associated with 3 Supreme Court rulings in 2022: (1) National Federation of Independent Business v Department of Labor, Occupational Safety and Health Administration (OSHA), which invalidated COVID-19 workplace protections; (2) New York State Rifle and Pistol Association Inc v Bruen, Superintendent of New York State Police (Bruen), which voided state laws restricting handgun carry; and (3) Dobbs v Jackson Women's Health Organization (Dobbs), which revoked the constitutional right to abortion. Data analysis was performed from July 1, 2022, to April 7, 2023. Main Outcomes and Measures: For the OSHA ruling, multiple data sources were used to calculate deaths attributable to COVID-19 among unvaccinated workers from January 4 to May 28, 2022, and the share of these deaths that would have been prevented by the voided protections. To model the Bruen decision, published estimates of the consequences of right-to-carry laws were applied to 2020 firearm-related deaths (and injuries) in 7 affected jurisdictions. For the Dobbs ruling, the model assessed unwanted pregnancy continuations, resulting from the change in distance to the closest abortion facility, and then excess deaths (and peripartum complications) from forcing these unwanted pregnancies to term. Results: The decision model projected that the OSHA decision was associated with 1402 additional COVID-19 deaths (and 22 830 hospitalizations) in early 2022. In addition, the model projected that 152 additional firearm-related deaths (and 377 nonfatal injuries) annually will result from the Bruen decision. Finally, the model projected that 30 440 fewer abortions will occur annually due to current abortion bans stemming from Dobbs, with 76 612 fewer abortions if states at high risk for such bans also were to ban the procedure; these bans will be associated with an estimated 6 to 15 additional pregnancy-related deaths each year, respectively, and hundreds of additional cases of peripartum morbidity. Conclusions and Relevance: These findings suggest that outcomes from 3 Supreme Court decisions in 2022 could lead to substantial harms to public health, including nearly 3000 excess deaths (and possibly many more) over a decade.

Black Household gun ownership and black suicide rates across U.S. States.

INTRODUCTION: Ecologic studies have examined the relationship across states between levels of household gun ownership and suicide rates using household gun ownership data from the Behavioral Risk Factor Surveillance System (BFRSS) or proxies. However, no study has examined how race-specific survey-based or proxy measures of gun ownership are related to race-specific suicide rates. METHODS: We use cross-sectional state-level race-specific data to examine how well various proxies correlate with race-specific BRFSS gun ownership rates. We examine whether BRFSS measures of household gun ownership are correlated with firearm suicide, non-firearm suicide, and total suicide rates, for Black and for White adults, and repeat these assessments with select proxies. The core BRFSS only included gun questions in 2001, 2002, and 2004, but not since; mortality data are collapsed 2001-2010. RESULTS: Among a set of proxies, the race-specific fraction of suicides that are firearm suicides (FS/S) is the measure most highly correlated with BRFSS household gun ownership. Across states, White adult BFRSS household gun ownership levels are highly correlated with White adult firearm suicide rates (correlation coefficient .82) and moderately correlated with White overall suicide rates (.63). However, for Black adults, we find that while the state-level Black gun ownership levels are moderately correlated with Black firearm suicide rates (.67)-more strongly for older (.70) than for younger (.47) Black adults-Black BRFSS gun ownership levels are only weakly correlated with Black overall suicide rates (.17) owing to a moderate inverse correlation with Black non-firearm suicide rates (-.45). For Black adults, the relationship between FS/S and suicide is similar to the relation between BRFSS and suicide. CONCLUSION: For White adults, states with higher levels of measured household gun ownership have higher overall suicide rates. This relationship does not hold for Black adults, largely due to a more attenuated correlation between these measures of firearm availability and firearm suicide rates coupled with a more substantial countervailing (inverse) relationship between these measures and non-firearm suicide rates. Future efforts using individual level data might help determine why this puzzling difference exists, especially for young Black adults.

Firearm licensure, lead levels and suicides in Massachusetts.

Nationally, between 2011 and 2019, suicide was the second leading cause of injury death, and about half of all suicides were firearm related. An overlooked factor connecting firearms and suicide is lead exposure. Lead bullets and primers are used throughout the US and pose danger to adults and children. Most (not all) studies link lead to mental illness, while others link lead with suicide. Research has linked lead and firearm violence, but rarely examined the relationship among firearms, lead exposure, and suicide. We collected data for cities/towns in Massachusetts between 2011 and 2019 regarding the number of firearm licenses, suicides, prevalence of blood lead levels, and covariates. We hypothesized that; 1) towns with higher levels of licensure will have higher levels of firearm suicides but licensure will have little relationship with non-firearm suicide; 2) towns with higher levels of licensures would have higher rates of lead exposure; 3) higher lead levels would be associated with higher rates of suicide by all methods. Individuals living in towns with higher rates of licensure were significantly more likely to die in firearm suicides and all suicide types. They were not more or less likely to die from non-firearm suicides. Lead was a predictor of all suicide types. Our study appears to be the first to show the established firearm suicide relationships holds within municipalities in a single state. We provide evidence concerning the link between lead exposure and suicide, particularly from firearms, and provide a glimpse into the relationship between firearm prevalence and elevated blood lead levels.

Patterns of household gun ownership and firearm suicide among black men compared to white men.

Little is known about the patterns of household gun ownership among Black Americans, so little is known about the relationship between the patterns of Black household gun ownership and the patterns of Black firearm suicide. We analyze data from the 2001-2004 Behavioral Risk Factor Surveillance System, the first and last years for which a gun question was part of the core questions. We compare household gun ownership patterns for Black men compared to White men across geographic (region, urbanicity), demographic (age, education, married, children at home), and health-related characteristics (binge drinking, smoking), and find that the patterns are quite similar for all eight variables. However, when we compare these race-specific patterns to the race-specific firearm suicide patterns for 2001-2004, while the White firearm suicide patterns follow their gun ownership patterns, the Black patterns do not. While gun ownership increases with age, adult male Black firearm suicide rates are highest in the younger age group-an age group that also has a high proportion of suicides that are firearm suicides. Differences in unadjusted demographic patterns in firearm suicide between Black men and White men cannot be explained by differences in the self-reported patterns of household gun ownership.

Defensive gun use: What can we learn from news reports?

BACKGROUND: In the past decade, most people who buy and own guns are doing so for self-defense. Yet little is known about actual defensive gun use in the USA. METHODS: To discover what information newspaper articles and local news reports might add, we read the news reports of defensive use incidents assembled by the Gun Violence Archive. We examined a sample of more than a quarter of the incidents from 2019, the last year before the pandemic. We examined all cases from four months-January, April, July, and October. We created a typology of defensive gun use incidents. RESULTS: Of 418 incidents, in about half, the perpetrator was armed with a firearm. In almost 90% of the cases, the victim fired their firearm-315 perpetrators were shot and about half of them died. The average number of perpetrators shot per incident was 0.75; the average number of victims shot was 0.25. We estimate that in 2019 fewer than 600 potential perpetrators were killed in defensive gun use incidents that made the news. Among the thirteen categories of shooting were drug-related (4% of incidents), gang-like combat (6%), romantic partner disputes (11%), escalating arguments (13%), store robberies (9%), street robberies (5%), unoccupied vehicle theft (5%), unarmed burglaries (7%), home invasions (20%), and miscellaneous (6%). CONCLUSION: We believe the Gun Violence Archive dataset includes the large majority of news reports of defensive gun use-and especially those in which the perpetrator is shot and dies. Some of the strengths of using news reports as a data source are that we can be certain that the incident occurred, and the reports provide us with a story behind the incident, one usually vetted in part by the police with occasional input from the victims, perpetrator, family, witnesses, or neighbors. Defensive gun use situations are quite diverse, and among the various categories of defensive gun use, a higher percentage of incidents in some of the categories seemed far less likely to be socially beneficial (e.g., drug-related, gang-like, escalating arguments) than in others (e.g., home invasions).

Lesson from the continuing 21st century motor vehicle success.

In 1999, the Centers for Disease Control and Prevention proclaimed the reduction in motor vehicle fatalities to be one of the great public health achievements of the 20th century. That motor vehicle success story has had enormous intellectual impact on the injury prevention field, providing many guiding lessons. Can we learn any lessons from what has happened to motor vehicle safety in the 21st century? A key lesson may come from the fact that the great injury achievement of reducing the motor vehicle death rate did not stop in 2000-it continued. We believe that is largely due to the 20th century creation of the conditions that promote continuous declines in injury. By contrast, in the firearms area, these conditions do not exist, and rates of death have not fallen, but have increased. As the idea of continuous quality improvement has become a staple in medicine, we should similarly have a focus on how to continuously reduce injuries. An important lesson from the 21st century motor vehicle success story for the injury prevention field is that we should put more strategic emphasis on creating the conditions that will lead to continuous reductions in injuries. But first we need a much better understanding of what those conditions are.

Who owned the gun in firearm suicides of men, women, and youth in five US states?

One way to reduce firearm suicide is to keep household guns away from a person at risk for suicide. To learn who owned (and presumably controlled access to) the guns used in suicide and which broad gun type they were, we examined National Violent Death Reporting System (NVDRS) data from 2015 to 2017 for five US states that supplied information on gun owner in over 80% of firearm suicides (AK, IA, NH, UT, WI). For adult males, 88% used their own gun; for women, 52% used their own gun and 32% used their partner's gun; for youth ages 18-20, 42% used their own gun, 43% used a family member's, and 8% used a friend's; for children, 19% used their own gun (usually a long gun) and 79% used a family member's gun. Almost 3/4 of firearm suicides involved a handgun, ranging from 62% for youth to 92% for women. In times of suicide risk, interventions for a youth should address not only the parents' guns, but those of other family members and the youth's own rifle or shotgun. For a woman, interventions need to address her own and her partner's guns. For a man, locking guns alone will confer little protection if he controls the keys or combination. Storing firearms-or a critical component-away from home or having someone else control the locks may be safer. Five NVDRS states provided useful data on who owned the gun used in firearm suicides. More NVDRS states should follow suit.

Associations between having been threatened or injured with a weapon and substance use and mental health among high school students in the United States.

Being threatened or injured with a weapon is a serious form of physical bullying. Little is known about the effects of being threatened or injured with a weapon on substance use and mental health among adolescents. A secondary analysis of 2017 Youth Risk Behavior Survey data assessed the associations between having been threatened or injured with a weapon and substance use (binge drinking, marijuana, tobacco use, prescription medication misuse) and mental health (feeling sad or hopeless, considering suicide). Multiple logistic regression models with complex survey weights were used, controlling for potential confounders. Approximately 6.0% of students reported having been threatened/injured with a weapon. After adjusting for covariates, having been threatened/injured with a weapon was associated with binge drinking (AOR = 2.5; 95% CI: 1.9-3.4), marijuana (AOR = 2.1; 95% CI: 1.6-2.7), tobacco use (AOR = 2.6; 95% CI: 2.0-3.5), and misuse of prescription medication (AOR = 2.2; 95% CI: 1.6-3.0) compared with students who have not been threatened/injured. Having been threatened/injured with a weapon was associated with 1.6 times the odds (95% CI: 1.2-2.2) of feeling sad/hopeless and 1.7 times the odds (95% CI: 1.3-2.3) of considering suicide. Having been threatened or injured with a weapon is an important public health issue associated with negative mental health and substance use.

Childhood Gender Nonconformity and Intimate Partner Violence in Adolescence and Young Adulthood.

Childhood gender nonconformity has been associated with numerous adverse experiences, including peer bullying and homophobic violence. However, little is known about gender nonconformity in the context of intimate relationships, independent of sexual orientation. This study aimed to examine associations between childhood gender nonconformity and intimate partner violence (IPV) in adolescence and early adulthood. Using data from the 2007 wave of the U.S. Growing Up Today Study (N = 7,641, mean age = 22.8 years), we estimated risk ratios (RRs) for the association of gender nonconformity up to age 11 years and lifetime IPV victimization and perpetration. Models were adjusted for demographic characteristics, including sexual orientation identity. We assessed effect modification by gender and examined whether childhood abuse mediated the association between nonconformity and IPV. Males in the top decile of nonconformity were at elevated risk of IPV victimization (RR = 1.40, 95% confidence interval [CI] = [1.15, 1.71]) and IPV perpetration (RR = 2.34, 95% CI = 1.54, 3.56) compared with those below median nonconformity, adjusting for sexual orientation and demographic characteristics. There was no evidence of a similar association for females in the top decile of gender nonconformity. Childhood abuse did not mediate IPV disparities by gender nonconformity. We identify gender nonconformity as an important risk indicator for IPV victimization and perpetration among young adult males, independent of sexual orientation. Findings highlight the vulnerability of boys and men who do not conform to societal gender norms and the importance of studying gender expression as a determinant of violence. IPV prevention efforts may be improved with more explicit focus on socially constructed gender norms and support for diverse gender expressions. Further research into the pathways between nonconformity and IPV and in more diverse populations is needed to build a more comprehensive understanding of the unique experiences gender nonconforming youth face.

Firearm-related research articles in health sciences by funding status and type: A scoping review.

Federal funding for firearm-related research in the health sciences has incurred Congressional restrictions and executive actions. Little is known about the funding landscape for published scholarship in this field. This study's aim was to characterize the number and sources of funding, including federal and non-federal sources, for firearm-related research articles published in health sciences journals. We performed a scoping review of original, empirical, peer-reviewed articles related to firearms published in health science journals and indexed in PubMed between January 2000 and December 2019, using the PRISMA extension for Scoping Review checklist. Four reviewers independently screened each article twice for inclusion. Included articles were reviewed again to identify funding sources. Articles were characterized as having explicitly declared funding, explicitly declared no funding, or no explicit funding declaration. Among articles with funding, we examined proportions by funding source. 812 articles met the inclusion criteria. 119 (14.7%) of the articles declared not having received any funding, and 240 (29.6%) had no funding declaration. 453 (55.8%) of the articles declared at least one source of funding. Of those, 221 (48.8%) reported at least one federal grant, and 232 (51.2%) reported at least one philanthropic grant. The number of published articles increased by 328.6% between 2000 and 2019. While the volume increased during the study period, the proportion of articles with funding was lower in 2019 (55.6%) than it was in 2000 (87.5%; proportion difference: 31.9%; 95% CI: 16.7%-47.2%). This study highlights the continued funding limitations in this field despite a growing volume of research.

Suicides at Shooting Ranges.

Background: Some shooting ranges have adopted policies to prevent suicides at their facilities. Little data have been available to guide them. Aim: We aimed to describe the incidence and characteristics of suicides at public shooting ranges. Method: We conducted text searches of 63,710 firearm suicides in the 16 states participating in the National Violent Death Reporting System from 2004 to 2015 to identify those occurring at public shooting ranges. Results: A total of 118 (or 0.18%) occurred at a shooting range, or 0.12 per million population. If that rate held for the nation as a whole, there would have been roughly 35 shooting range suicides per year during the study period. In total, 88% of decedents arrived alone. When gun ownership was noted, 86% of guns were rented from the range. In some cases, people drove to the range and took their lives in the parking lot with their own gun. Limitations: Our search strategy may have missed cases, and the data may not be nationally representative. Conclusion: Suicides at shooting ranges are rare. Policies that some ranges have adopted - such as allowing rentals only if the person is not alone - are responsive to the actual characteristics of these deaths and could potentially prevent most.
