Despite the minimum legal drinking age of 21, many underage persons regularly purchase alcohol from licensed alcohol establishments. The purpose of this study was to determine the establishment, geographic, and community economic and demographic characteristics that are associated with illegal sales of alcohol to underage persons in Georgia. Multivariate logistic regression analysis was used to determine factors that were associated with illegal sales of alcohol to underage persons of Georgia. Statistical adjustments were made for ownership type (e.g., corporate owned), region (e.g., southeast Georgia, metro-Atlanta), rural vs. urban area, and many community economic and demographic variables (e.g., unemployment rate, minority populations). Overall, underage subjects attempted to purchase alcohol in 2949 off-premise establishments from July of 2007 to June of 2008. Compared to corporate-owned establishments, institutions not owned by corporations were associated with increased odds of alcohol sale to underage persons, adjusting for other independent variables. Establishments that are located in counties with a high density of alcohol outlets were much more likely to sell alcohol to underage persons. To reduce underage drinking in Georgia, beverage law enforcement should increase monitoring of non-corporate owned establishments and areas with a high density of alcohol outlets. Overall, responsible beverage service training of both corporate and non-corporate employees may help in reducing alcohol sales to underage persons in Georgia.

Introduction: Adolescents in the United States use alcohol more than any other substance, including tobacco and marijuana. Continuing alcohol misuse has numerous adverse health effects and is linked to liver disease, cancer, cardiovascular disease and neurological damage. Furthermore, alcohol consumption is a significant risk factor for unsafe sexual behaviors, unintentional injuries, physical and sexual assaults, various types of illegal activities, and suicide (USDHHS, 2007). Aim: The purpose of this study is to compare the individual social indicators from 4 categories that have been identified within the literature as being particularly associated with alcohol consumption in general, and underage alcohol consumption in particular. The categories used were: drinking consequences, urbanicity, poverty, and alcohol outlet density. The social indicators in these categories will be compared in the 10 most-at-risk counties (MAR) and the 10 least-at-risk counties (LAR), and the 20 MAR counties and the 20 LAR counties, as they relate to underage alcohol consumption. Methods: The counties were identified in and data was obtained from Governor’s Cooperative Agreement State Incentive Planning and Development Grant: Social Indicator Study to Assess Substance Use Prevention Needs at the State and County Levels in Georgia. An independent 2-tailed t-test was conducted to compare the means of groups in both the 10 MAR/LAR counties and the 20 MAR/LAR counties. Results: Significant differences were observed in all of the individual indicators in the poverty and alcohol outlet density categories for both the 10 MAR/LAR counties and the 20 MAR/LAR counties. Discussion: There needs to be a more accurate, specific and efficient methods of data surveillance concerning underage drinking behavior. Further research should focus on urbanicity, poverty, and alcohol outlet density as they relate to underage alcohol consumption. There were differences observed between the MAR and LAR counties in all of the poverty alcohol outlet density indicators, and researchers and policy makers should pay special attention to these two areas when designing further research and prevention policies.

Increases in alcohol availability have caused crime rates to escalate across multiple regions around the world. As individuals consume alcohol they experience impaired judgment and a dose-response escalation in aggression that, for some, leads to criminal behaviour. By limiting alcohol availability it is possible to reduce crime; however, the literature remains mixed on the best practices for alcohol access restrictions. Variances in data quality and statistical methods have created an inconsistency in the reported effects of price, hour of sales, and alcohol outlet restrictions on crime. Most notably, the research findings are influenced by the different effects of alcohol establishments on crime. The objective of this PhD research was to develop novel quantitative approaches to establish the extent alcohol access (outlets) influences the frequency of crime (liquor, disorder, violent) at a fine level of spatial detail (x,y locations and block groups). Analyses were focused on British Columbia’s largest cities where policies are changing to allow greater alcohol access, but little is known about the crime-alcohol access relationship. Two reviews were conducted to summarize and contrast the effects of alcohol access restrictions (price, hours of sales, alcohol outlet density) on crime, and evaluate the state-of-the-art in statistical methods used to associate crime with alcohol availability. Results highlight key methodological limitations and fragmentation in alcohol policy effects on crime across multiple disciplines. Using a spatial data science approach, recommendations were made to increase spatial detail in modelling to limit the scale effects on crime-alcohol association. Providing guidelines for alcohol-associated crime reduction, kernel density space-time change detection methods were also applied to provide the first evaluation of active policing on alcohol-associated crime in the Granville St. entertainment district of Vancouver, British Columbia. Foot patrols were able to reduce the spatial density of crime, but hot spots of liquor and violent assaults remained within 60m proximity to bars (nightclubs). To estimate the association between alcohol establishment size, and type on disorder and violent crime reports in block groups across Victoria, British Columbia a Poisson Generalized Linear Model with spatial lag effects was applied. Estimates provided the factor increase (1.0009) expected in crime for every additional patron seat added to an establishment capacity, and indicated that establishments should be spaced greater than 300m a part to significantly reduce alcohol-associated crime. These results offer the first evaluation of seating capacity and establishment spacing on alcohol-associated crime for alcohol license decision making, and are pertinent at a time when alcohol policy reform is being prioritized by the British Columbia government. In summary, this dissertation contributes 1) cross-disciplinary policy and methodological reviews, 2) expands the application of spatial statistics to alcohol-attributable crime research, 3) advances knowledge on local scale of effects of different alcohol establishment types on crime, 4) and develops transferable models to estimate the effects of alcohol establishment seating capacity and proximity between establishments on the frequency of crime. / Graduate / 2018-02-27
