Medical Marijuana Dispensaries and Referrals for Child Maltreatment Investigations.

The changing legal status of marijuana in the United States has increased access to the drug through medical marijuana dispensaries. Limited research exists that examines the effects of these dispensaries on social problems including child maltreatment. The current study examines how medical marijuana dispensaries may affect referrals for child abuse and neglect investigations. Data are analyzed from 2,342 Census tracts in Los Angeles County, California. Locations of medical marijuana dispensaries were obtained through Weedmaps.com. Using conditionally autoregressive models, local and spatially lagged dispensaries show a positive relationship to rates of referrals in the unadjusted models. However, when we adjust for alcohol outlet density and measures of social disorganization, this relationship is no longer significant. Although this study does not find a relationship between medical marijuana dispensaries and referrals for investigations of child maltreatment, it should not be considered a definitive finding of this relationship. The increasing number of states that are allowing marijuana to be used for medical and recreational purposes is resulting in more people using the drug and the effects on parenting are still unknown.

Participatory Methodologies With Adolescents: A Research Approach Used to Explore Structural Factors Affecting Alcohol Use and Related Unsafe Sex in Tanzania.

Multiple methodological approaches have been used to explore adolescent alcohol use and related sexual behaviors, ranging from surveys to assessments of alcohol outlet density. Although surveys can capture the extent of alcohol use, they do not allow for a contextualized understanding of young people's voiced experiences with alcohol, including sociocultural, gendered and environmental pressures to consume, and related engagement in sex. The mapping of alcohol outlets provides physical density information, but infrequently from youths' perspectives. Traditional qualitative methods like in-depth interviews and focus group discussions do allow for a more nuanced understanding of adolescents' experiences, but they can be limited by the use of semi-structured guides that may negatively impact the fluidity of discussion. We seek to contribute to the methodological approaches utilized with adolescents by demonstrating how contextualized data were captured from Tanzanian adolescents' experiences of alcohol and sex, which are sensitive topics in many African countries. We collected data in secondary schools and youth centers across four sites in Dar es Salaam, the largest and most diverse city in Tanzania. As a complement to in-depth interviews, archival reviews, and a systematic mapping of alcohol availability, participatory methodologies such as photovoice, story writing, and drawing allowed Tanzanian youth to offer more honest, descriptions of lived experiences with their physical and social environment in relation to alcohol use and related sexual behavior patterns. Through participatory methods, study participants were able to discuss behaviors that are viewed as social transgressions, sensitive topics like violence in relation to sex, and views around their own self-agency. The use of a methodological toolkit including participatory methodologies enabled youth to trust the researchers and share sensitive information in a relatively short period of time, overcoming some of the challenges of traditional qualitative methods.

Association between state-level alcohol availability and taxation policies on the prevalence of alcohol-related harms to persons other than the drinker in the USA, 2000-2015.

Alcohol-related harms to others (AHTO) are consequences of alcohol use borne by persons other than the drinker. This study assessed whether the odds of experiencing AHTO are associated with alcohol availability and taxation policies. This study pooled data from four waves of the National Alcohol Survey (n = 20656 adults). We measured past-year AHTO exposure using three binary variables: physical (pushed/hit/assaulted or property damage by someone who had been drinking), family or financial (family/marital problems or financial harms by someone who had been drinking) and driving AHTO (riding in a vehicle with a drink-driver or being in a drink-driving crash). Policies included bar and off-premise alcohol outlet density (separately), alcohol retail hours, beer and spirits taxes (separately) and monopoly on retail/wholesale alcohol purchases. Monopolies were associated with 41.2% lower odds of physical harms [adjusted odds ratio (aOR) = 0.59, 95% confidence interval (CI) 0.45, 0.77, q < 0.001 correcting for multiple analyses], and a 10% increase in bar density was associated with a 1.2% increase in odds of driving-related harms ( e ln(1.1) * β =1.01, 95% CI 1.00, 1.02, q = 0.03). Among men, beer taxes were associated with lower odds of physical harms ( eln(1.1) * β =0.93, 95% CI 0.88, 0.98 q = 0.03) and monopolies were associated with lower odds of physical (aOR = 0.45, 95% CI 0.35, 0.59, q < 0.001) and driving harms (aOR = 0.66, 95% CI 1.00, 1.02, q = 0.03). Monopolies, taxes and outlet density are associated with odds of some AHTO. Future longitudinal research should test whether physical availability and taxation policies may be protective for bystanders as well as drinkers.

Alcohol Outlet Density and Deprivation in Six Towns in Bergrivier Municipality before and after Legislative Restrictions.

Introduction. In 2016, after the Western Cape Liquor Act was enacted, alcohol outlets were mapped in the six towns from a previous 2008 study to determine: (1) alcohol outlet density; (2) the association between deprivation and alcohol outlet density; (3) geospatial trends of alcohol outlet densities; and (4) the impact of alcohol legislation. Methods. Latitude and longitude coordinates were collected of legal and illegal alcohol outlets, and alcohol outlet density was calculated for legal, illegal and total alcohol outlets by km2 and per 1000 persons. To determine the impact of legislation, t-tests and hot spot analyses were calculated for both 2008 and 2016 studies. Spearman coefficients estimated the relationship between alcohol outlet density and deprivation. Results. Although not statistically significant, the number of alcohol outlets and the density per 1000 population declined by about 12% and 34%, respectively. Illegal outlets were still more likely to be located in more deprived areas, and legal outlets in less deprived areas; and a reduction or addition of a few outlets can change a town’s hot spot status. Conclusions. Further studies with larger sample sizes might help to clarify the impacts of the Liquor Act, and the more recent 2017 Alcohol-Related Harms Reduction Policy on alcohol outlet density in the province.

Alcohol Advertising and Violence

Numerous studies have found associations between alcohol outlet density and violence, but it is unknown whether alcohol advertisements visible outside outlets are also associated with violent crime. Baltimore City, MD enacted restrictions on retail alcohol establishment advertising practices as of June 5, 2017. This study examines the association between alcohol advertisements visible outside off-premise alcohol outlets and violent crime before this restriction. Outlet observations (n=683) were conducted in summer 2015, and violent crime data (n=24,085) were from June 5, 2015, through June 4, 2017. The number of violent crimes per square mile within 1,000 feet of outlets was summed using kernel density estimation. In 2018-2019, authors used mixed models with a Simes-Benjamini-Hochberg correction for multiple testing. Roughly half (47%, n=267) of the outlets with complete data (n=572) had alcohol advertisements visible from the exterior. Outlets with alcohol advertisements had 15% more violent crimes per square mile within 1,000 feet (eβ=1.15, 95% CI=1.07, 1.25, q<0.001) after adjusting for neighborhood context. All associations between alcohol advertisements and specific types of violent crime were significant, with the association strongest for homicides (eβ=1.28, 95% CI=1.13, 1.46, q<0.001). There was no association between cigarette advertisements and violent crime (eB=1.08, 95% CI=0.92, 1.26, q=0.43). Alcohol advertisements visible outside off-premise outlets were associated with increased violent crime over and above the association between the outlets themselves and violent crime. Reducing alcohol advertising visible from the street may decrease risk of violent crime that is associated with alcohol outlets.

Trends in Total Binge Drinks per Adult Who Reported Binge Drinking - United States, 2011-2017.

Each year, excessive drinking accounts for one in 10 deaths among U.S. adults aged 20-64 years (1), and approximately 90% of adults who report excessive drinking* binge drink (i.e., consume five or more drinks for men or four or more drinks for women on a single occasion) (2). In 2015, 17.1% of U.S. adults aged ≥18 years reported binge drinking approximately once a week and consumed an average of seven drinks per binge drinking episode, resulting in 17.5 billion total binge drinks, or 467 total binge drinks per adult who reported binge drinking (3). CDC analyzed 2011-2017 Behavioral Risk Factor Surveillance System (BRFSS) data to assess trends in total annual binge drinks per adult who reported binge drinking in the United States overall and in the individual states. The age-adjusted† total annual number of binge drinks per adult who reported binge drinking increased significantly from 472 in 2011 to 529 in 2017. Total annual binge drinks per adult who reported binge drinking also increased significantly from 2011 to 2017 among those aged 35-44 years (26.7%, from 468 to 593) and 45-64 years (23.1%, from 428 to 527). The largest percentage increases in total binge drinks per adult who reported binge drinking during this period were observed among those without a high school diploma (45.8%) and those with household incomes <$25,000 (23.9%). Strategies recommended by the Community Preventive Services Task Force§ for reducing excessive drinking (e.g., regulating alcohol outlet density) might reduce binge drinking and related health risks.

Binge drinking, alcohol outlet density and associated factors: a multilevel analysis among adolescents in Belo Horizonte, Minas Gerais State, Brazil.

Our study sought to evaluate the prevalence of binge drinking in adolescents and its association with density of alcohol outlets around schools. This cross-sectional study was conducted in Belo Horizonte, Minas Gerais State, Brazil, with 436 high-school students aged between 17 and 19 and enrolled in 18 public and private schools. The students completed the Alcohol Use Disorder Identification Test (AUDIT-C), consisting of questions about alcohol consumption by parents and siblings, and socioeconomic status (type of school, mother's education level). Data from geographic information systems were used to estimate the density of alcohol outlets around schools participating. The association between exploratory variables and binge drinking was investigated using multilevel logistic regression analysis (p < 0.05) with random intercepts and fixed slopes. A three-step sequential modeling strategy was adopted. The prevalence of binge drinking was 39.9%. The alcohol consumption among adolescents was lower for those studying in areas with low density of alcohol outlets around schools (OR = 0.32; 95%CI: 0.14; 0.73) and the consumption of alcohol by mothers was associated with binge drinking among adolescents (OR = 1.94; 95%CI: 1.14; 3.30). Our study concluded that binge drinking among adolescents was associated with density of alcohol outlets around the schools and mother's alcohol consumption.

Is alcohol outlet density in the residential area associated with alcohol consumption among adolescents?

To investigate the association between the alcohol outlet density in residential areas and the current and lifetime alcohol consumption, adjusted for individual and family factors. Information from a three-stage household stratified probabilistic cluster sampling survey (census tract, household, adult and adolescent), conducted in Belo Horizonte, Brazil ("Health in BH", 2008-2009) and data of the establishments were obtained from official sources and subsequently georeferenced. The outcome was the adolescents' report of current and lifetime alcohol consumption. The exposure variable was the alcohol outlet density, defined as the number of establishments within a 200-meter range from the adolescents' residence. The association was estimated by Poisson regression adjusted by individual and family variables. In total, 601 adolescents aged 14 to 17 years were included in this study. Of these, 53.3% were males and 71.0% lived in a family with income up to five minimum wages. The prevalence of lifetime alcohol consumption was 57.0% (95%CI 51.5 - 62.6) and the current was 11.9% (95%CI 8.7 - 15.0). The multivariate analysis showed a significant association between current alcohol consumption and density of snack bars (PR = 1.13; 95%CI 1.03 - 1.24), bars (PR = 1.21; 95CI% 1.05 - 1.38), and restaurants (PR = 1.11; 95%CI 1.02 - 1.21). Significant interactions between density of establishments with sex and age were found. Current alcohol consumption may be enhanced by the availability of some types of establishments located within a range of 200 meters from the adolescents' residence.

Restricting alcohol outlet density through cumulative impact provisions in planning law: Challenges and opportunities for local governments.

There is international interest in how to limit growth in alcohol availability in areas of high outlet density in order to reduce alcohol-related harms. Town planning legislation in Victoria, Australia, allows local government officers to refuse planning permits for new licensed premises on 'cumulative impact' grounds (impacts from existing alcohol outlet density). State guidelines (PN61) outline how local government planners should approach cumulative impact assessments. This paper explores officers' views and experience assessing cumulative impact in order to understand whether the legislation assists officers limit alcohol availability in areas of high outlet density. Interviews with 22 officers from 11 local governments who were recruited with purposive sampling to reflect a range of licensing environments. Interview transcripts were analysed inductively, and content categorized accordingly. Officers challenged the definition and relevance of the alcohol outlet density threshold provided in state guidelines. They faced problems securing relevant amenity data for assessing cumulative impact and pointed to the guidelines' inadequacy for assessing off-premise licences. They pointed to the limits of cumulative impact assessments as a tool for planning and were unconvinced they would lead to reductions in permits granted. A single state-wide density threshold to guide cumulative impact assessments is unlikely to be a relevant measure for several local governments. A greater orientation towards municipal variation and alcohol outlet characteristics is needed. Further research is needed to investigate whether cumulative impact assessments increase restrictions on liquor licence planning permits and whether the adoption of local planning policies strengthens restrictive permit decision-making. International implications of the research are noted.

Alcohol consumption and alcohol policy in Estonia 2000-2017 in the context of Baltic and Nordic countries.

Introduction and AimsAlcohol consumption has become a global health threat and there is need for an evidence‐based global alcohol policy. This study aimed to describe alcohol consumption in parallel with alcohol policy in 2000–2017 in Estonia in the context of Baltic and Nordic countries.Design and MethodsA review of routine statistics concerning alcohol consumption and the pertinent legislation in Estonia was performed. The measures used to assess the effects of alcohol policy were adult (15 and older) pure alcohol per capita consumption (APC) in litres, alcohol outlet densities and opening hours, taxes and the price of alcoholic beverages.ResultsAdult domestic APC in Estonia increased from 9.3 to 14.8 in 2000–2007 and thereafter decreased to 10.2 in 2016 (10.3 in 2017). Adult APC in Estonia was lower than that in Latvia and Lithuania but higher than that in Nordic countries. Since 2010, beer has been the most prevalent alcoholic beverage in Estonia. The density and opening hours of alcohol retail shops were much higher in Estonia and other Baltic countries than in Nordic countries. The alcohol retail price increased twice from 2006 to 2017 in Estonia, resulting in a double price difference with Latvia.Discussion and ConclusionsEvidence‐based comprehensive alcohol policy should continue in Estonia. Based on the example of Nordic countries, more attention should be paid to the physical availability of alcohol in Estonia. In terms of economic availability, it is important to focus on the cross‐border alcohol trade to achieve improvements in public health.

A Spatial Analysis of Alcohol Outlet Density and Abandoned Properties on Violent Crime in Paterson New Jersey.

Alcohol outlet density (AOD) and abandoned or vacant properties in under-served urban communities has received increased attention and has been linked to community violence. While previous research has examined the AOD and violent crime association, less research has investigated the relationship between abandoned properties and violent crime. Those studies that are present examining the AOD-abandoned properties-violent crime link have been plagued by flaws that include statistical weaknesses and aggregated datasets that investigated larger units such as states or countries. The present study, using Geographic Information Systems (GIS) mapping, spatial analysis techniques, and a regression-based approach examines the association between AOD and abandoned properties on violent crime, controlling for demographic characteristics, in Paterson, New Jersey. Results provide some evidence on the association between AOD and abandoned properties on violent crime, drawing conclusions for policy and practice.

Impact of Alcohol Outlet Density on Reported Cases of Child Maltreatment in Japan: Fixed Effects Analysis.

Background: Parental drinking habits or binge drinking are a known risk factor of child maltreatment. Though drinking habits are affected by alcohol outlet density, the direct association between alcohol outlet density and child maltreatment is still controversial.Purpose: This study aimed to examine the impact of off-premises alcohol outlet density on child maltreatment cases reported to Child Guidance Centers in Japan.Methods: A fixed effects model was used to investigate the association between a change in off-premises alcohol outlet density and a change in child maltreatment cases in each unit. Time-series of cross-sectional ecological data collected from across Japan over 16 years (2000 to 2015) was used, and maltreatment cases were further sub-grouped by type of maltreatment (physical, sexual, psychological abuse and neglect) and by perpetrators (father, stepfather, mother, and stepmother).Results: The association between alcohol outlet density and total cases of child maltreatment was not observed (coefficient = 0.98, 95% confidence interval: −6.30, 8.25). However, alcohol outlet density was shown to be positively associated with neglect (coefficient = 3.08, 95% confidence interval: 0.54, 5.62), which indicates that 1 alcohol outlet per 1,000 adults increase would lead to 3 more neglect cases per 10,000 children. Also, a negative association was observed between a change in the incidence of total child maltreatment by father and a change in alcohol outlet density (coefficient = −3.03, 95% confidence interval: −5.78, −0.28).Conclusion: The findings suggest that off-premises alcohol outlet density may have a causal effect on the increasing cases of neglect and decrease in maltreatment by father in Japan.

Proximity and Density of Alcohol Outlets as a Risk Factor of Alcohol Abuse Amongst the Youth: A Case Study of a Border Town in Northern Region of Namibia

The proximity and density of alcohol outlets are positively associated with drinking patterns and increase in alcohol consumption resulting in deviant behaviors such as excessive drinking, risky sexual behaviors, violent and crime in communities. This study was aimed at identifying and assessing the proximity, density of alcohol outlets as a risk factor to potential behavioral influence amongst the youth in a border town in the northern region of Namibia. The study was qualitative in nature and used ethnographic design in order to describe the proximity and density of alcohol outlets. Data was collected through unobtrusive observation method and analyzed by means of content analysis. The researchers used field notes to capture data observed. Eco-systems theory was used as a theoretical framework for this study. The study found out that there were quite a number of shebeens in close proximity of educational establishments, churches, public roads and residential areas which contribute to easy accessibility of alcohol by youth in and out of school. Various themes emerged from the study such as closeness of alcohol outlets to schools and churches and residential areas, mushrooming of shebeens, children and youth spending time at shebeens and Drunkenness. The study concluded that the closeness of alcohol establishments to residential areas, churches and schools influence drinking behaviors of people residing in these areas. Equally important, the more alcohol outlets in the environment, the higher the alcohol consumption which results in deviant behaviors and excessive drinking.

Activity Spaces: Assessing Differences in Alcohol Exposures and Alcohol Use for Parents.

Parental alcohol use and alcohol outlet densities in residential areas are related to risk for child maltreatment. However, some parents spend significant time outside of their residential neighborhood. Thus, we may not be accurately assessing how alcohol environments are related to risks for problematic parenting. Here, we examine how residential environments and activity spaces are related to outlet density and whether drinking events in our sample of parents differ by location (e.g., routine vs. rare locations) and whether their children are present. We conducted semi-structured interviews with 60 parents living in four cities in the San Francisco Bay area who provided information on where they spent time, where they drank, and whether children were present. We constructed measures of activity spaces (e.g., convex hull polygons) and activity patterns (e.g., shortest network distance) and calculated outlet density in each. Density of alcohol outlets for residential Census tract was not related to density of the activity space and activity pattern measures. Alcohol use occurred more frequently (regardless of whether their children were present) inside activity spaces operationalized as convex hull polygons or two standard deviational ellipses. Measures that capture larger activity space areas (e.g., convex hull polygons, two standard deviational ellipses) may better model where people spend time, regardless of whether the location is routine or rare. By continuing to use activity spaces to explore relationships between outlet densities, drinking behaviors, and problems, we can start to ascertain those mechanisms by which outlets may affect local problems.

Societal determinants of violent death: The extent to which social, economic, and structural characteristics explain differences in violence across Australia, Canada, and the United States.

In this ecological study, we attempt to quantify the extent to which differences in homicide and suicide death rates between three countries, and among states/provinces within those countries, may be explained by differences in their social, economic, and structural characteristics. We examine the relationship between state/province level measures of societal risk factors and state/province level rates of violent death (homicide and suicide) across Australia, Canada, and the United States. Census and mortality data from each of these three countries were used. Rates of societal level characteristics were assessed and included residential instability, self-employment, income inequality, gender economic inequity, economic stress, alcohol outlet density, and employment opportunities). Residential instability, self-employment, and income inequality were associated with rates of both homicide and suicide and gender economic inequity was associated with rates of suicide only. This study opens lines of inquiry around what contributes to the overall burden of violence-related injuries in societies and provides preliminary findings on potential societal characteristics that are associated with differences in injury and violence rates across populations.

Neighbourhood context and binge drinking from adolescence into early adulthood in a US national cohort.

Underage binge drinking is a serious health concern that is likely influenced by the neighbourhood environment. However, longitudinal evidence has been limited and few studies have examined time-varying neighbourhood factors and demographic subgroup variation. We investigated neighbourhood influences and binge drinking in a national cohort of US 10th grade students at four times (2010-2014; n = 2745). We estimated odds ratios (OR) for past 30-day binge drinking associated with neighbourhood disadvantage, personal and property crime (quartiles), and number of liquor, beer and wine stores within 5 km, and then evaluated whether neighbourhood associations differ by age, sex and race/ethnicity. Neighbourhood disadvantage was associated with binge drinking before 18 [OR = 1.54; 95% confidence interval (1.14, 2.08)], but not after 18 years of age. Property crime in neighbourhoods was associated with a higher odds of binge drinking [OR = 1.54 (0.96, 2.45)], an association that was stronger in early adulthood [4th vs 1st quartile: OR = 1.77 (1.04, 3.03)] and among Whites [4th vs 1st quartile: OR = 2.46 (1.03, 5.90)]. Higher density of liquor stores predicted binge drinking among Blacks [1-10 stores vs none: OR = 4.31 (1.50, 12.36)] whereas higher density of beer/wine stores predicted binge drinking among Whites [one vs none for beer: OR = 2.21 (1.06, 4.60); for wine: OR = 2.04 (1.04, 4.03)]. Neighbourhood conditions, particularly those related to economic circumstances, crime and alcohol outlet density, were related to binge drinking among young adults, but associations varied across age and individual characteristics.

Methods for Evaluating the Association Between Alcohol Outlet Density and Violent Crime.

The objective of this analysis was to compare measurement methods-counts, proximity, mean distance, and spatial access-of calculating alcohol outlet density and violent crime using data from Baltimore, Maryland. Violent crime data (n=11,815) were obtained from the Baltimore City Police Department and included homicides, aggravated assaults, rapes, and robberies in 2016. We calculated alcohol outlet density and violent crime at the census block (CB) level (n=13,016). We then weighted these CB-level measures to the census tract level (n=197) and conducted a series of regressions. Negative binomial regression was used for count outcomes and linear regression for proximity and spatial access outcomes. Choropleth maps, partial R2 , Akaike's Information Criterion, and root mean squared error guided determination of which models yielded lower error and better fit. The inference depended on the measurement methods used. Eight models that used a count of alcohol outlets and/or violent crimes failed to detect an association between outlets and crime, and 3 other count-based models detected an association in the opposite direction. Proximity, mean distance, and spatial access methods consistently detected an association between outlets and crime and produced comparable model fits. Proximity, mean distance, and spatial access methods yielded the best model fits and had the lowest levels of error in this urban setting. Spatial access methods may offer conceptual strengths over proximity and mean distance. Conflicting findings in the field may be in part due to error in the way that researchers measure alcohol outlet density.

The influence of alcohol outlet density and advertising on youth drinking in urban Tanzania.

Despite the detrimental effects of alcohol on adolescent health, high rates of alcohol use are reported among Tanzanian youth. We conducted systematic community mapping and participatory group activities with 177 adolescents in Dar es Salaam to explore how alcohol outlet density and advertising may contribute to adolescent drinking in urban Tanzania. Findings revealed a high density of alcohol-selling outlets and outdoor advertisements. The abundance of alcohol-related cues, including their close proximity to places where youth congregate, may facilitate and increase adolescent alcohol use in Tanzania. Participants recommended several changes to the alcohol environment to reduce adolescent drinking. Structural interventions that reduce adolescents' access and exposure to alcohol are needed in Tanzania.

Psychosocial and Demographic Factors That Compound Alcohol Abuse Amongst Youth: A Case Study of Musina High School

The risk factors that compound alcohol abuse by young people have significant effects of individuals. The sole purpose of social work is to enhance the social functioning of clients and in most cases, clients have impairments as the result of high density of alcohol outlets, affordability of alcohol, which later give birth to psychosocial challenges. The aim of this study is to describe psychosocial and demographic factors compounding alcohol abuse amongst youth. The study employed quantitative approach and descriptive case study design. Data was collected at Musina High School and 96 learners were sampled using stratified sampling to complete the questionnaire. Data was analysed descriptively with the aid of Statistical Package for the Social Science. The study revealed that psychosocial and environmental factors compound to alcohol abuse amongst youth in Musina High School. The study concludes that the context determines the excessive use of alcohol abuse by youth. Young people especially those who reside in rural areas are exposed to high density of alcohol outlets and they are left without guardianship. Due to lack of guardian or parental involvement they end up indulging in excessive use of alcohol.

Measuring Alcohol Outlet Density: An Overview of Strategies for Public Health Practitioners.

Excessive alcohol use is responsible for 88 000 deaths in the United States annually and cost the United States $249 billion in 2010. There is strong scientific evidence that regulating alcohol outlet density is an effective intervention for reducing excessive alcohol consumption and related harms, but there is no standard method for measuring this exposure. We overview the strategies available for measuring outlet density, discuss their advantages and disadvantages, and provide examples of how they can be applied in practice. The 3 main approaches for measuring density are container-based (eg, number of outlets in a county), distance-based (eg, average distance between a college and outlets), and spatial access-based (eg, weighted distance between town center and outlets). While container-based measures are the simplest to calculate and most intuitive, distance-based or spatial access-based measures are unconstrained by geopolitical boundaries and allow for assessment of clustering (an amplifier of certain alcohol-related harms). Spatial access-based measures can also be adjusted for population size/demographics but are the most resource-intensive to produce. Alcohol outlet density varies widely across and between locations and over time, which is why it is important to measure it. Routine public health surveillance of alcohol outlet density is important to identify problem areas and detect emerging ones. Distance- or spatial access-based measures of alcohol outlet density are more resource-intensive than container-based measures but provide a much more accurate assessment of exposure to alcohol outlets and can be used to assess clustering, which is particularly important when assessing the relationship between density and alcohol-related harms, such as violent crime.
