Federal Firearm Licensee Rates and Suicide in Maryland, 2014 to 2019

INTRODUCTION

Federal firearm licensee density is associated with interpersonal firearm violence. Yet the role of Federal firearm licensees in firearm suicide remains understudied, even though firearms are the method used in more than half of suicides. This study tested associations between the spatial distribution of federal firearm licensees and firearm suicides in Maryland.

METHODS

Kernel density estimation measured federal firearm licensee and suicide rates at the census tract level (n=1,397), and SaTScan detected clusters of licensees and suicides. Choropleth maps compared visual associations between federal firearm licensee, firearm, and non-firearm suicide rates and clusters. Generalized estimating equations tested associations between Federal firearm licensee rates and clusters and the odds of using a firearm as the lethal means overall and after stratifying by biological sex. Data were obtained in 2020 and analyzed in 2020-2024.

RESULTS

The federal firearm licensee rate was associated with greater odds of firearm suicide overall (aOR=1.29, 95% CI=1.21, 1.38, p<0.001), for men (aOR=1.29, 95% CI=1.20, 1.39, p<0.001), and for women (aOR=1.26, 95% CI=1.07, 1.49, p=0.007). Suicide decedents in a census tract located in a federal firearm licensee cluster (vs not) had higher odds of firearm use overall (aOR=1.70, 95% CI=1.28, 2.27, p<0.001) and for men (aOR=1.67, 95% CI=1.22, 2.27, p=0.001), but not for women (aOR=1.65, 95% CI=0.81, 3.34, p=0.168).

CONCLUSIONS

The federal firearm licensee rate and clusters were associated with firearm suicides and unrelated to the spatial distribution of non-firearm suicides. Prevention approaches that limit the number of these federal firearm licensees or alter their sales practices, such as federal firearm licensee zoning and land use provisions, advertising restrictions, or gun shop projects, may prevent firearm suicides.

Protocol for creating a dataset of U.S. state alcohol-related firearm laws 2000-2022

Firearms are a major source of preventable morbidity and mortality in the United States, contributing to over 48,000 deaths in 2022 and generating societal costs in excess of $500 billion. A body of work has examined the relationship between US state level firearm laws and health outcomes, generally finding that some firearm regulations are associated with lower firearm-related mortality. Alcohol has been identified as an additional risk factor for both homicides and suicide and stronger state alcohol laws have been associated with lower rates of suicide. To date, there are no empirical studies that have investigated the impact of laws over a long period of time that target the intersection of alcohol and firearm. One reason for this may be because there is no existing dataset that includes the range of these state laws over time. This study describes the protocol for collecting, coding and operationalizing these legal data.

Alcohol, Aggression, and Violence: From Public Health to Neuroscience

Alcohol has been associated with violent crimes and domestic violence across many nations. Various etiological factors were linked to chronic alcohol use and violence including psychiatric comorbidities of perpetrators such as personality disorders, mood disorders, and intermittent explosive disorders. Aggression is the precursor of violence and individuals prone to aggressive behaviors are more likely to commit impulsive violent crimes, especially under the influence of alcohol. Findings from brain studies indicate long-term alcohol consumption induced morphological changes in brain regions involved in self-control, decision-making, and emotional processing. In line with this, the inherent dopaminergic and serotonergic anomalies seen in aggressive individuals increase their susceptibility to commit violent crimes when alcohol present in their system. In relation to this, this article intends to investigate the influence of alcohol on aggression with sociopsychological and neuroscientific perspectives by looking into comorbidity of personality or mood disorders, state of the mind during alcohol consumption, types of beverages, environmental trigger, neurochemical changes, and gender differences that influence individual responses to alcohol intake and susceptibility to intoxicated aggression.

Alcohol Policy Scores and Alcohol-Attributable Homicide Rates in 150 Countries

INTRODUCTION

More comprehensive state-level alcohol policy environments are associated with lower alcohol-attributable homicide rates in the U.S., but few studies have explored this internationally. This study tests whether 3 national-level alcohol policy scores are associated with alcohol-attributable homicide rates.

METHODS

Data were from the 2016 WHO Global Survey on Alcohol and Health and the 2017 Global Burden of Disease Study (N=150 countries). In 2020, the authors calculated domain-specific alcohol policy scores for physical availability, marketing, and pricing policies. Higher scores represented more comprehensive/restrictive alcohol policy environments. Negative binomial regressions with Benjamini-Simes-Hochberg multiple testing correction measured the associations between policies and alcohol-attributable homicide rates. Authors stratified countries by World Bank income group to determine whether the associations differed among low- and middle-income countries.

RESULTS

A 10% increase in the alcohol policy score for pricing was associated with an 18% lower alcohol-attributable homicide rate among all the countries (incidence rate ratio=0.82, adjusted p-value or q<0.001) and with a 14% (incidence rate ratio=0.86, q=0.01) decrease among 107 low- and middle-income countries. More controls on days and times of retail sales (incidence rate ratio=0.96, q=0.01) and affordability of alcohol (incidence rate ratio=0.95, q=0.04) as well as adjusting excise taxes for inflation (incidence rate ratio=0.96, q<0.01) were associated with a 4%-5% lower alcohol-attributable homicide rate in the full sample.

CONCLUSIONS

Countries with policies that reduce alcohol's affordability or days/hours of sales tend to have fewer alcohol-attributable homicides, regardless of their income level. Alcohol-attributable homicide rates are highest in low- and middle-income countries; policies that raise alcohol-relative prices may hold promise for curbing these harms.
