Alcohol Involvement in Homicide Victimization in the United States

Integrated behavioral interventions for adults with alcohol use disorder: A systematic review

BACKGROUND

This systematic review synthesized evidence from randomized controlled trials (RCTs) on the effects of integrated behavioral interventions for adults with alcohol use disorder (AUD).

METHODS

A comprehensive search of three databases was conducted in 2022, utilizing terms related to alcohol/substance use disorders and integrated interventions. The sample included adults aged ≥18 years at low, moderate, or high risk for AUD, and had at least two other mental health conditions. Only RCTs were included and screened using Covidence. The quality of the study was evaluated using Cochrane risk of bias tool.

RESULTS

Across all 11 studies, the total AUD participants were 1543 aged 18 or older. Integrated intervention led to significant reductions in heavy drinking compared to usual care or other interventions. Measures included percent days of alcohol use, grams of alcohol consumed, and increased days of abstinence. Three studies compared integrated treatments with Twelve-Step Facilitation, indicating a better abstinence rate among participants in the integrated group at the end of treatment. Comparisons between delivery modes demonstrated more significant reductions in alcohol consumption with interventionists. Integrated interventions were also compared with various other treatments, including brief intervention, telephone and individual counseling, and psychological education. Participants in the integrated group showed greater improvement in alcohol consumption and depression compared to those in the standalone intervention group.

CONCLUSIONS

Integrated behavioral interventions effectively reduce alcohol consumption, decrease heavy drinking and promote alcohol abstinence. However, there is limited evidence to determine whether these interventions are more effective than usual care for individuals with AUD.

Were the scale of excitability a circle: Tracing the roots of the disease theory of alcoholism through Brunonian stimulus dependence

The disease theory of alcoholism, and by extension, of addiction, forms the theoretical basis of an expansive scientific industry, one which musters tremendous resources in the service of research, rehab clinics, and government programs. Revisiting the early work on the disease theory of alcoholism, this paper analyzes the apperance of the disease theory of alcoholism in the eighteenth/nineteenth century works of Rush, Trotter, and Brühl-Cramer as emergent of a theoretical tension within the Brunonian system of medicine, that of stimulus dependence. Establishing both the shared Brunonianism of these figures and the concept of stimulus dependence, I argue it is here that one finds the nascent formulation of the modern dependence model of addiction, pushing out alternative models, such as Hufeland's toxin theory.

The Impact of Aggregate Level Alcohol Consumption on Homicide Rates: A Time Series Analysis

Consumption of alcohol has an impact on violent crimes and homicides. The study examines the association between aggregate level consumption of spirit and homicide rates in the State of Kerala in India. Time-series analyses were conducted by building Autoregressive Moving Average with Exogenous Variables (ARMAX) models and OLS Regression models to explain the relationship between the monthly rate of consumption of alcoholic spirits and homicide rates. The study concludes that consumption of alcoholic spirits has a statistically significant impact on the total homicide rates and the male and female homicide rates. The study has significant policy implications being one of the first studies examining the relationship between alcohol consumption and homicide rates in India and suggesting methods to address challenges of adverse public health consequences associated with alcohol consumption.

The Cannabis Policy Scale: A New Research and Surveillance Tool for U.S. States

OBJECTIVE

Rapid shifts toward cannabis liberalization in the United States have created immense policy variability that is challenging to measure. We developed composite measures to characterize the restrictiveness of U.S. state cannabis policy environments.

METHOD

Nine panelists, consisting of four research team members and five expert policy consultants, nominated distinct cannabis policies pertaining to cannabis prohibition, medicalization, and legalization for recreational use. For each of the 17 nominated policies, panelists developed implementation ratings and rated each policy's relative efficacy for reducing excessive cannabis use by adults, youth use, and impaired driving. Cannabis Policy Scale scores were then calculated for each state-year for all 50 states from 1999 to 2019 by weighting policies by their efficacy and implementation ratings, and then summing over policies.

RESULTS

Median Cannabis Policy Scale scores remained stable until 2008, when they started declining (representing policy liberalization), with steeper declines after 2012. In 2019, state Cannabis Policy Scale scores targeting excessive use among the general population ranged from 29.6 to 66.7 for recreational cannabis legalization states, and from 72.4 to 93.4 for medical cannabis legalization states. Cannabis Policy Scale scores using youth-specific and driving-specific efficacy ratings showed similar trends.

CONCLUSIONS

The Cannabis Policy Scale reflects trends toward liberalization of cannabis policy in many U.S. states. Even within crude policy phenotypes (e.g., medical cannabis programs), Cannabis Policy Scale scores varied considerably between states and over time. The Cannabis Policy Scale is a new measure that can add nuance to cannabis policy research and help assess cannabis policy-outcome relationships.

Alcohol Consumption and 15 Causes of Fatal Injuries: A Systematic Review and Meta-Analysis

INTRODUCTION

The proportion of fatal nontraffic injuries that involve high levels of alcohol use or alcohol intoxication was assessed by cause of injury to generate alcohol-attributable fractions. Updated alcohol-attributable fractions can contribute to improved estimates of the public health impact of excessive alcohol use.

METHODS

Peer-reviewed and gray literature for 1995-2019 on 15 causes of fatal nontraffic injuries in the U.S., Canada, or Mexico were systematically reviewed, and state data systems were queried for available estimates of fatalities with recorded blood alcohol concentration levels and proportions of decedents with blood alcohol concentrations ≥0.10 g/dL by cause of injury. For each injury cause, alcohol-attributable fractions across studies were synthesized by meta-analysis of single proportions using generalized linear mixed models.

RESULTS

In total, 60 published studies and 40 additional population-level data points from 6 state data systems were included. The meta-analyzed alcohol-attributable fractions by cause of injury are as follows: air-space transport (0.03), aspiration (0.24), child maltreatment (0.09), drowning (0.31), fall injuries (0.37), fire injuries (0.34), firearm injuries (0.24), homicide (0.29), hypothermia (0.29), motor vehicle nontraffic crashes (0.42), occupational and machine injuries (0.08), other road vehicle crashes (railroad trespasser injuries) (0.63), poisoning (not alcohol) (0.20), suicide (0.21), and water transport (0.27), yielding an overall median alcohol-attributable fraction of 0.27.

DISCUSSION

Excessive alcohol use is associated with substantial proportions of violent and nonviolent injury deaths. These findings can improve the data used for estimating alcohol-attributable injury deaths and inform the planning and implementation of evidence-based strategies (e.g., increasing alcohol taxes, regulating alcohol outlet density) to prevent them.

Hazardous drinking and violence-related hospitalizations in the Danish general population: A historical cohort study

BACKGROUND

It is well documented by case-control and case-crossover studies that hazardous drinking and the risk of experiencing violence-related injuries are related. The present study investigated this relationship in a cohort of general population survey respondents in Denmark using subsequent hospital admissions for violence.

METHODS

The cohort consisted of participants in the 2011 Danish national survey on alcohol and drugs (N = 5126). Survey responses were used to identify those with hazardous alcohol use. Register data on the cohort's hospital admissions for violence from 2010 through 2018 served as the outcome. The relationship between respondents' hazardous drinking and counts of subsequent hospital admissions was investigated using a Poisson regression model.

RESULTS

After controlling for confounding, respondents with hazardous consumption (Alcohol Use Disorders Identification Test Consumption [AUDIT-C] cut off: 5 points) had an increased rate of hospital admissions for violence, with an incidence rate ratio (IRR) of 2.28 (95% CI: 1.16-4.50) compared to respondents without hazardous alcohol use. Each additional AUDIT-C point was associated with a 20% increase in the incidence rate for violence-related admission (IRR=1.20, 95% CI: 1.06-1.37). Furthermore, interaction analyses showed a significant interaction between gender and AUDIT-C score on hospital admissions for violence (IRR=0.69, 95% CI: 0.53-0.90).

CONCLUSIONS

Results provide evidence that hazardous alcohol use is associated with subsequent hospital admissions for violence in the Danish general population and that gender moderates this relationship.

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.

Alcohol testing and alcohol involvement among violent deaths by state, 2014-2016

Blood alcohol concentration (BAC) testing rates vary across states, potentially biasing estimates of alcohol involvement in violent deaths. The National Violent Death Reporting System (NVDRS) collects information on violent deaths, including decedents' BACs. This study assessed characteristics of violent deaths by BAC testing status, and the proportion of decedents with a positive BAC or BAC ≥ 0.08 g/dL. NVDRS data from 2014 to 2016 (2014: 18 states; 2015: 27 states; 2016: 32 states) were analyzed to assess BAC testing (tested, not tested, unknown/missing) by state, decedent characteristics, and death investigation system (e.g., state medical examiner, coroners), in 2019. The proportion of violent deaths with a BAC > 0.0 or ≥ 0.08 g/dL was also assessed. Among 95,390 violent death decedents, 57.1% had a BAC test (range: 9.5% in Georgia to 95.8% in Utah), 2.3% were not tested, and 40.6% had an unknown/missing BAC testing status (range: 1.3% in Alaska to 78.0% in Georgia). Decedents who were 21-44 years, American Indian/Alaska Native or Hispanic, died by poisoning, died by undetermined intent, or were investigated by a state medical examiner were most likely to receive BAC testing. Among the violent deaths with a reported BAC, 41.1% had a positive BAC and 27.7% had a BAC ≥ 0.08 g/dL. About 2 in 5 violent deaths were missing data on alcohol testing. Increased testing and reporting of alcohol among violent deaths could inform the development and use of evidence-based prevention strategies (e.g., increasing alcohol taxes, regulating alcohol outlet density) for reducing violent deaths.

Trauma trends during COVID-19 alcohol prohibition at a South African regional hospital

Introduction

The objective of this study was to examine the relationship between trauma volume and alcohol prohibition during the COVID‐19 lockdown in South Africa.

Methods

This was a retrospective analysis of trauma volume from Worcester Regional Hospital in South Africa from 1 January to 28 December 2020. We compared total volume and incidence rates during five calendar periods; one when alcohol sales were allowed as per normal and four when alcohol sales were completely or partially banned. Poisson regression was used to model differences between alcohol ban and non‐ban periods.

Results

During the first period (pre‐COVID‐19, no ban), the trauma admission rate was 95 per 100 days, compared to 39 during the second period (complete ban 1), 74 during the third period (partial ban 1), 40 during the fourth period (complete ban 2) and 105 during the fifth period (partial ban 2). There was a 59–69% decrease in trauma volume between the no ban and complete ban 1 periods. When alcohol sales were partially reinstated, trauma volume significantly increased by 83–90% then dropped again by 39–46% with complete ban 2. By the second half of 2020, when alcohol sales were partially allowed again (partial ban 2), trauma volume increased by 163–250%, thus returning to pre‐COVID‐19 levels.

Discussion and Conclusions

Our study demonstrates a clear trend of decreased trauma volume during periods of complete alcohol prohibition compared to non‐ and partial alcohol bans. This finding suggests that temporary alcohol bans can be used to decrease health facility traffic during national emergencies.

Bringing the commercial determinants of health out of the shadows: a review of how the commercial determinants are represented in conceptual frameworks

BACKGROUND

The term 'commercial determinants of health' (CDOH) is increasingly focussing attention upon the role of tobacco, alcohol and food and beverage companies and others-as important drivers of non-communicable diseases (NCDs). However, the CDOH do not seem to be clearly represented in the most common social determinants of health (SDOH) frameworks. We review a wide range of existing frameworks of the determinants of health to determine whether and how commercial determinants are incorporated into current SDOH thinking.

METHODS

We searched for papers and non-academic reports published in English since 2000 describing influences on population health outcomes. We included documents with a formal conceptual framework or diagram, showing the integration of the different determinants.

RESULTS

Forty-eight framework documents were identified. Only one explicitly included the CDOH in a conceptual diagram. Ten papers discussed the commercial determinants in some form in the text only and fourteen described negative impacts of commercial determinants in the text. Twelve discussed positive roles for the private sector in producing harmful commodities. Overall, descriptions of commercial determinants are frequently understated, not made explicit, or simply missing. The role of commercial actors as vectors of NCDs is largely absent or invisible in many of the most influential conceptual diagrams.

CONCLUSIONS

Our current public health models may risk framing public health problems and solutions in ways that obscure the role that the private sector, in particular large transnational companies, play in shaping the broader environment and individual behaviours, and thus population health outcomes.

Alcohol Policies and Motor Vehicle Crash Deaths Involving Blood Alcohol Concentrations Below 0.08

INTRODUCTION

Motor vehicle crashes are a leading cause of injury death in the U.S. Restrictive alcohol policies protect against crashes involving alcohol above the legal blood alcohol concentration of 0.08%. Characteristics of motor vehicle crash fatalities involving blood alcohol concentrations below the limit and their relationships to alcohol control policies have not been well characterized.

METHODS

Motor vehicle crash fatality data and crash and decedent characteristics from 2000 to 2015 came from the Fatality Analysis Reporting System and were analyzed in 2018-2019. Alcohol Policy Scale scores characterized alcohol policy environments by state-year. Generalized estimating equation alternating logistic regression models assessed these scores and the odds that a fatality involved alcohol below the legal threshold.

RESULTS

Of 612,030 motor vehicle crash fatalities, 223,471 (37%) died in alcohol-involved crashes, of which 33,965 (15% of alcohol-involved fatalities or 6% of all fatalities) had a blood alcohol concentration <0.08%. A 10 percentage point increase in Alcohol Policy Scale score, approximating the interquartile range among states, was associated with reduced odds of fatalities involving alcohol <0.08% vs 0.00% (AOR=0.91, 95% CI=0.89, 0.93). These findings held across multiple subgroup analyses by decedent and crash characteristics. Similar results were found for odds of alcohol involvement <0.05% vs 0.00% (AOR=0.90, 95% CI=0.88, 0.93), and ≥0.05% but <0.08% vs <0.05% (AOR=0.93, 95% CI=0.89, 0.96).

CONCLUSIONS

The number of lower blood alcohol concentration fatalities is substantial. States with more restrictive alcohol policies tend to have reduced odds of lower blood alcohol concentration motor vehicle crashes than states with weaker policies.

Alcohol Consumption and Violent Deaths in the City of Sao Paulo in 2015

Background: Excessive alcohol consumption is a serious public health issue, because drunkenness affects critical judgment and self-control, making people more vulnerable to violence and accidents, with thus a potential association between alcohol consumption and violent deaths. Objective: To assess the association between alcohol consumption and violent deaths in the city of Sao Paulo, Brazil, in 2015, and its relationship with gender, age, cause of death and blood alcohol concentration (BAC) of victims. Methods: A cross-sectional retrospective study was conducted by collection of data from 2,882 victims of violent deaths subjected to examination of BAC from the archives of the Institute of Legal Medicine of the State of Sao Paulo, Brazil. Results: Alcohol was detected in blood samples of 27.06% of the victims and mean BAC levels were 1.92 ± 1.24 g/L. The mean age of the victims was 33.49 ± 15.19 years. The majority of the victims were male (84.14%) and the prevalence of positive BAC was higher amongst men (28.74%) than women (18.16%). Homicide was the most prevalent cause of death in the sample (36.57%), but there were a higher proportion of traffic accidents victims with positive BAC (32.01%), as well as higher BAC levels in these victims (46.77% in the range of 1.6-2.5 g/L). Conclusions: The results obtained in this study support a potential association between alcohol consumption and violent deaths in the city of Sao Paulo, mainly in traffic accidents victims.

Alcohol Policies and Alcohol Involvement in Intimate Partner Homicide in the U.S

INTRODUCTION

Intimate partner violence (IPV) results in deaths of both primary and corollary (i.e., nonintimate partner) victims. Alcohol use is a known risk factor for IPV, yet the relationship between alcohol policies and IPV homicides is unclear. This repeated cross-sectional study characterizes alcohol involvement, and the relationship between alcohol policies and alcohol involvement, among victims of IPV homicides in the U.S.

METHODS

Homicide victim data from 17 states in the National Violent Death Reporting System from 2003 to 2012 were analyzed in 2017-2018. Alcohol Policy Scale scores characterized alcohol policies by state year and were used in generalized estimating equation logistic regression models to predict the odds of alcohol involvement among victims of IPV homicide.

RESULTS

Among victims of IPV homicide, 36.5% of primary and 41.1% of corollary victims had a blood alcohol concentration (BAC) >0.00%. Of the victims with a positive BAC, 67.6% had a BAC ≥0.08%. In adjusted models, a 10-percentage point increase in Alcohol Policy Scale score was associated with reduced odds of having a positive BAC (AOR=0.77, 95% CI=0.64, 0.93) and having a BAC ≥0.08% (AOR=0.82, 95% CI=0.68, 0.99) among all victims, primary victims (AOR=0.78, 95% CI=0.63, 0.98; AOR=0.82, 95% CI=0.65, 1.04), and corollary victims (AOR=0.61, 95% CI=0.42, 0.89; AOR=0.68, 95% CI=0.48, 0.97).

CONCLUSIONS

Alcohol use was prevalent among victims of IPV homicide, and more-restrictive alcohol policies were associated with reduced odds of alcohol involvement. Strengthening alcohol policies is a promising strategy to reduce alcohol-involved IPV homicide victimization.

Assessing the impact of alcohol taxation on rates of violent victimization in a large urban area: an agent-based modeling approach

AIMS

To use simulation to estimate the impact of alcohol taxation on drinking, non-fatal violent victimization and homicide in New York City (NYC). We simulate the heterogeneous effects of alcohol price elasticities by income, level of consumption and beverage preferences, and examine whether taxation can reduce income inequalities in alcohol-related violence.

DESIGN

Agent-based modeling simulation.

SETTING

NYC, USA.

PARTICIPANTS

Adult population aged 18-64 years in the year 2000 in the 59 community districts of NYC. The population of 256 500 agents approximates a 5% sample of the NYC population.

MEASUREMENTS

Agents were parameterized through a series of rules that governed alcohol consumption and engagement in violence. Six taxation interventions were implemented based on extensive reviews and meta-analyses, increasing universal alcohol tax by 1, 5 and 10%, and beer tax by 1, 5 and 10%.

FINDINGS

Under no tax increase, approximately 12.2% [95% credible interval (prediction interval, PI) = 12.1-12.3%] were heavy drinkers. Taxation decreased the proportion of heavy drinkers; a 10% tax decreased heavy drinking to 9.6% (95% PI = 9.4-9.8). Beer taxes had the strongest effect on population consumption. Taxation influenced those in the lowest income groups more than the highest income groups. Alcohol-related homicide decreased from 3.22 per 100 000 (95% PI = 2.50-3.73) to 2.40 per 100 000 under a 10% universal tax (95% PI = 1.92-2.94). This translates into an anticipated benefit of ~1200 lives/year.

CONCLUSION

Reductions in alcohol consumption in a large urban environment such as New York City can be sustained with modest increases in universal taxation. Alcohol tax increases also have a modest effect on alcohol-related violent victimization. Taxation policies reduce income inequalities in alcohol-related violence.

Alcohol in combination with illicit drugs among fatal injuries in Sao Paulo, Brazil: An epidemiological study on the association between acute substance use and injury

Injury deaths have a major impact on public health systems, particularly in the Latin American region; however, little is known about how different drugs, in combination or not with alcohol, interact with each injury type. We tested an epidemiological protocol for investigating alcohol and other drug acute use among fatally injured victims taking into account the injury context for all injury causes in Sao Paulo, Brazil. Blood alcohol and drug content were fully screened and confirmed following a probability sample selection of decedents (n = 365) during 19 consecutive months (2014-2015). Drug concentrations, including benzodiazepines, cannabis, cocaine, and opioids were determined by gas chromatography-mass spectrometry (GC-MS) or liquid chromatography tandem mass spectrometry (LC-MS/MS). Toxicology data were interpreted in combination with injury context retrieved from police records regarding cause, place of injury, and victims' criminal history. More than half of all fatally injured victims studied were under the influence of at least one substance (55.3%). Alcohol was the leading substance consumed before a fatal injury event (30.1%), followed by cocaine (21.9%) and cannabis (14%). Illicit drug use (cocaine and cannabis) comprised more than two thirds of all drug-related deaths. Alcohol-positive deaths are over-represented among road traffic injuries, while drug-positive deaths are more prevalent among intentional injuries. Victims who had previous criminal convictions were significantly more likely to have used illicit drugs compared to those who did not have a criminal background. We estimated that one in every two fatal injuries in the city of Sao Paulo is associated with acute substance use by the victim. The health burden attributed to alcohol- and drug-related fatal injury events has reached significant higher levels in Latin American cities such as Sao Paulo compared globally.

Outlet Type, Access to Alcohol, and Violent Crime

BACKGROUND

While there are overwhelming data supporting the association between alcohol outlet density and violent crime, there remain conflicting findings about whether on- or off-premise outlets have a stronger association. This inconsistency may be in part a result of the methods used to calculate alcohol outlet density and violent crime. This analysis uses routine activity theory and spatial access methods to study the association between access to alcohol outlets and violent crime, including type of outlet and type of crime in Baltimore, MD.

METHODS

The data in this analysis include alcohol outlets from 2016 (n = 1,204), violent crimes from 2012 to 2016 (n = 51,006), and markers of social disorganization, including owner-occupied housing, median annual household income, drug arrests, and population density. The analysis used linear regression to determine the association between access to alcohol outlets and violent crime exposure.

RESULTS

Each 10% increase in alcohol outlet access was associated with a 4.2% increase in violent crime exposure (β = 0.43, 95% CI 0.33, 0.52, p < 0.001). A 10% increase in access to off-premise outlets (4.4%, β = 0.45, 95% CI 0.33, 0.57, p < 0.001) and LBD-7 outlets (combined off- and on-premise outlets; 4.2%, β = 0.43, 95% CI 0.33, 0.52, p < 0.001) had a greater association with violent crime than on-premise outlets (3.0%, β = 0.31, 95% CI 0.20, 0.41, p < 0.001).

CONCLUSIONS

Access to outlets that allow for off-site consumption had a greater association with violent crime than outlets that only permit on-site consumption. The lack of effective measures to keep order in and around off-premise outlets could attract or multiply violent crime.

Alcohol Policies and Alcohol-Involved Homicide Victimization in the United States

OBJECTIVE

The purpose of this study was to examine the associations between the alcohol policy environment and alcohol involvement in homicide victims in the United States, overall and by sociodemographic groups.

METHOD

To characterize the alcohol policy environment, the presence, efficacy, and degree of implementation of 29 alcohol policies were used to determine Alcohol Policy Scale (APS) scores by state and year. Data about homicide victims from 17 states from 2003 to 2012 were obtained from the National Violent Death Reporting System. APS scores were used as lagged exposure variables in generalized estimating equation logistic regression models to predict the individual-level odds of alcohol involvement (i.e., blood alcohol concentration [BAC] > 0.00% vs. = 0.00% and BAC ≥ 0.08% vs. ≤ 0.079%) among homicide victims.

RESULTS

A 10 percentage point increase in APS score (representing a more restrictive policy environment) was associated with reduced odds of alcohol-involved homicide with BAC greater than 0.00% (adjusted odds ratio [AOR] = 0.89, 95% CI [0.82, 0.99]) and BAC of 0.08% or more (AOR = 0.91, 95% CI [0.82, 1.02]). In stratified analyses of homicide victims, more restrictive policy environments were significantly protective of alcohol involvement at both BAC levels among those who were female, ages 21-29 years, Hispanic, unmarried, victims of firearm homicides, and victims of homicides related to intimate partner violence.

CONCLUSIONS

More restrictive alcohol policy environments were associated with reduced odds of alcohol-involved homicide victimization overall and among groups at high risk of homicide. Strengthening alcohol policies is a promising homicide prevention strategy.
