The effectiveness of limiting alcohol outlet density as a means of reducing excessive alcohol consumption and alcohol-related harms

Racial/ethnic differences in the etiology of alcohol use among urban adolescents

OBJECTIVE

We examined relations between neighborhood context, home and family management practices, deviant peer affiliations, beliefs favorable to use, and alcohol use among urban African American and Hispanic adolescents.

METHOD

The sample comprised 4,027 African American and Hispanic adolescents who were 50% boys and 75% low income. Participants completed surveys in 2002-2005 and 2008-2009. Structural equation modeling assessed direct and indirect relations between neighborhood context in 6th grade, home and family management practices in 7th grade, deviant peer affiliations and beliefs favorable to use in 8th grade, and alcohol use in 12th grade.

RESULTS

There was significant variation in structural models across race/ethnicity but not gender. Differences included the influence of neighborhood and school strength and, where similarities existed, differences in effect magnitude. Similarities included significant correlations among measurement components; the indirect influence of alcohol advertisement exposure, gender, area deprivation, and home alcohol access on alcohol use; direct influence of deviant peer affiliations and beliefs favorable to use on alcohol use; and indirect effects highlighting the importance of preventing home alcohol access, deviant peer affiliations, and beliefs favorable to use and promoting protective family management practices.

CONCLUSIONS

Neighborhood and school strength may be particularly important in preventing alcohol use among African Americans, whereas preventing early onset of alcohol use among Hispanics remains important. Preventive efforts may wish to focus on neighborhood deprivation, exposure to alcohol advertisements, and home risks and protective factors because they have direct and indirect effects on intrapersonal factors and alcohol use.

The manufacture of lifestyle: the role of corporations in unhealthy living

Recently, researchers have debated two views on the connection between lifestyle and health. In the first, health-related lifestyles including tobacco and alcohol use, diet, and physical activity are seen as primary influences on health. In the second, social stratification is the dominant influence with lifestyles simply markers of social status. Neither approach leads to interventions that can reverse the world's most serious health problems. This article proposes that corporate practices are a dominant influence on the lifestyles that shape patterns of health and disease. Modifying business practices that promote unhealthy lifestyles is a promising strategy for improving population health. Corporations shape lifestyles by producing and promoting healthy or unhealthy products, creating psychological desires and fears, providing health information, influencing social and physical environments, and advancing policies that favor their business goals. Public officials and health professionals can promote health by advocating policies to modify these corporate practices.

Alcohol outlet density and harm: comparing the impacts on violence and chronic harms

INTRODUCTION AND AIMS

A number of studies have previously identified relationships between the density of alcohol outlets and rates of violence, with different types of outlets related to violence in different locations. The previous work in Australia has been limited to studies based on police data, which are subject to numerous biases. This study extends the previous work by utilising hospital admissions as a less biased outcome measure, incorporating a 14 year longitudinal design and by developing comparative models for violence and rates of alcohol use disorders.

DESIGN AND METHODS

The study examines trends in postcode-level hospital admission data for assault and for alcohol use disorders over a 14 year period (n = 186) and their relationship with the density of three kinds of alcohol outlets. Fixed-effects models are developed to control for the differences between postcodes and for the overall trends in outlet density and morbidity rates.

RESULTS

The results of this study suggest that the density of alcohol outlets where the main activity is alcohol consumption (i.e. pubs) is positively related to rates of assault-related hospital admissions, while the density of off-premise alcohol outlets is related to the rate of alcohol use disorders.

DISCUSSION AND CONCLUSIONS

These findings have significant implications for alcohol policies in Victoria, in particular pointing to the significant contribution of packaged alcohol outlets to both acute and chronic alcohol-related harm.

The impact of retail practices on violence: the case of single serve alcohol beverage containers

INTRODUCTION AND AIMS

This paper examines the role that sales of single serve alcoholic beverages plays in violent crime in surrounding areas. Increasingly a target of regulatory measures, this is the first study to systematically assess the impact of single serve containers on neighbourhood violence.

DESIGN AND METHODS

The relative proportion of shelf space in each liquor establishment in San Bernardino, CA devoted to single serve alcohol containers was surveyed. Assuming that this is a rough indicator of the amount of sales derived from single serve containers, we use this indicator as a measure of the impact of specific retail practice on violence around the outlet.

RESULTS

Results show that the average proportion of shelf space devoted to single serve containers in the unit of analysis, the US Census Bureau block group, was positively related to violent crime, net of overall retail availability of alcohol and relevant social and economic indicators often used to predict violent crime rates in such units.

DISCUSSION AND CONCLUSIONS

These findings suggest that if the city were to make the voluntary ban on single serve container sales mandatory, violence in the surrounding areas would decline, all other things being equal. This study provides a much more grounded and specific justification for enacting such policy changes and once again shows the utility of alcohol policy for the reduction of crime and violence.

Violence victimization of young men in heterosexual relationships: does alcohol outlet density influence outcomes?

This study examined whether alcohol outlet density is associated with male physical and sexual victimization by a female partner. Data were from the National Longitudinal Study of Adolescent Health (Add Health). A total of 3,179 young adult men identified a current heterosexual relationship and had complete intimate partner violence (IPV) victimization data. Almost 16% of this sample reported being the victim of physical only IPV in their relationship over the previous 12 months; an additional 6.4% were victims of sexual only or sexual and physical IPV. Multivariate analyses indicated high alcohol outlet density was associated with greater odds of experiencing physical IPV only (odds ratio [OR] = 2.07). Heavy drinkers experienced increased odds of physical and sexual IPV victimization. Alcohol outlet density should be addressed in prevention efforts.

Research gaps related to tobacco product marketing and sales in the Family Smoking Prevention and Tobacco Control Act

This paper is part of a collection that identifies research priorities that will help guide the efforts of the U.S. Food and Drug Administration (FDA) as it regulates tobacco products. This paper examines the major provisions related to tobacco product advertising, marketing, sales, and distribution included in Public Law 111-31, the "Family Smoking Prevention and Tobacco Control Act". This paper covers 5 areas related to (a) marketing regulations (e.g., ban on color and imagery in ads, ban on nontobacco gifts with purchase); (b) granting FDA authority over the sale, distribution, accessibility, advertising, and promotion of tobacco and lifting state preemption over advertising; (c) remote tobacco sales (mail order and Internet); (d) prevention of illicit and cross-border trade; and (e) noncompliant export products. Each of the 5 sections of this paper provides a description and brief history of regulation, what is known about this regulatory strategy, and research opportunities.

Levels of explanation in psychiatric and substance use disorders: implications for the development of an etiologically based nosology

The soft medical model for psychiatric illness, which was operationalized in DSM-III, defines psychiatric disorders as syndromes with shared symptoms, signs, course of illness and response to treatment. Many in our field want to move to a hard medical model based on etiological mechanisms. This essay explores the feasibility of this move and asks whether psychiatric disorders have the needed single clear level of explanation for an etiologically based nosology. I propose seven criteria for a good explanation: (i) strength, (ii) causal confidence, (iii) generalizability, (iv) specificity, (v) manipulability, (vi) proximity and (vii) generativity. Applying them to cystic fibrosis, a gene-level approach to etiology performs well across the board. By contrast, a detailed review of alcohol dependence and a briefer review of major depression suggests that psychiatric disorders have multiple explanatory perspectives no one of which can be privileged over others using scientific data alone. Therefore, a move toward an etiologically based diagnostic system cannot assume that one level of explanation will stand out as the obvious candidate on which to base the nosology. This leaves two options. Either a hard medical model will be implemented that will require a consensus about a preferred level of explanation which must reflect value judgments as well as science. To take this approach, we need to agree on what we most want from our explanations. Alternatively, we will need to move away from the traditional hard medical model that requires that we ground our diagnoses in single biological essences, and focus instead on fuzzy, cross-level mechanisms, which may more realistically capture the true nature of psychiatric disorders.

The case against a smoker's license

Tobacco continues to kill millions of people around the world each year and its use is increasing in some countries, which makes the need for new, creative, and radical efforts to achieve the tobacco control endgame vitally important. One such effort is discussed in this PLOS Medicine Debate, where Simon Chapman presents his proposal for a "smoker's license" and Jeff Collin argues against. Chapman sets out a case for introducing a smart card license for smokers designed to limit access to tobacco products and encourage cessation. Key elements of the smoker's license include smokers setting daily limits, financial incentives for permanent license surrender, and a test of health risk knowledge for commencing smokers. Collin argues against the proposal, saying that it would shift focus away from the real vector of the epidemic--the tobacco industry--and that by focusing on individuals it would censure victims, increase stigmatization of smokers, and marginalize the poor.

Using a legal and regulatory framework to identify and evaluate priorities for cancer prevention

This paper presents a framework for identifying legal and regulatory interventions for the prevention of risk factors for cancer at the population level. The framework has wider application for behavioural risk factors for other non-communicable diseases. It is based on four different types of assessment: identifying the determinants of cancer and key settings for interventions; reviewing the key strategies that law can deploy; considering the most appropriate level for interventions within federal systems; and considering the role of law within a broader set of public health responses that includes voluntary standards, co-regulation, outcome-based regulation and more technical, prescriptive controls. The paper argues that law is an important tool for preventing the burden of disease from cancer. It then uses the framework to evaluate the current status of regulatory strategies for cancer prevention and to identify law reform priorities, taking Australia as a case study. The paper illustrates the application of the model at the country level by making extensive use of Australian evidence and published research. However, the methodology presented, the regulatory issues discussed, the evidence cited and the law reform priorities identified will be relevant to other countries with a substantial burden from cancer and non-communicable diseases.

Hospital admission rates for alcoholic intoxication after policy changes in the canton of Geneva, Switzerland

BACKGROUND

In February, 2005, the canton of Geneva in Switzerland prohibited the off-premise sale of alcoholic beverages between 9 pm and 7 am, and banned their sale in gas stations and video stores. The aim of this study is to assess the impact of this policy change on hospital admission rates for alcoholic intoxication.

METHODS

An interrupted time series analysis of this natural experiment was performed with data on hospitalisations for acute alcoholic intoxication during the 2002-2007 period. The canton of Geneva was treated as the experimental group, while all other Swiss cantons were used as the control group.

RESULTS

In the experimental site, the policy change was found to have a significant effect on admission rates among adolescents and young adults. Depending on the age group, hospitalisation rates for alcoholic intoxication fell by an estimated 25-40% as the result of restricted alcohol availability.

CONCLUSIONS

Modest restrictions on opening hours and the density of off-premise outlets were found to be of relevance for public health in the canton of Geneva. In light of this finding, policy makers should consider such action as a promising approach to alcohol prevention.

Creating nurturing environments: a science-based framework for promoting child health and development within high-poverty neighborhoods

Living in poverty and living in areas of concentrated poverty pose multiple risks for child development and for overall health and wellbeing. Poverty is a major risk factor for several mental, emotional, and behavioral disorders, as well as for other developmental challenges and physical health problems. In this paper, the Promise Neighborhoods Research Consortium describes a science-based framework for the promotion of child health and development within distressed high-poverty neighborhoods. We lay out a model of child and adolescent developmental outcomes and integrate knowledge of potent and malleable influences to define a comprehensive intervention framework to bring about a significant increase in the proportion of young people in high-poverty neighborhoods who will develop successfully. Based on a synthesis of research from diverse fields, we designed the Creating Nurturing Environments framework to guide community-wide efforts to improve child outcomes and reduce health and educational inequalities.

Effectiveness of public health programs for decreasing alcohol consumption

Excessive alcohol consumption and the associated negative consequences are a major public health concern in the United States and throughout the world. Historically, there have been numerous attempts to develop policies and prevention programs aimed at decreasing high-risk alcohol use. Policy initiatives have demonstrated considerable effectiveness and include changes in the minimum legal drinking age, reductions in acceptable legal limits for blood alcohol concentration while operating a motor vehicle, as well as decreasing availability and access to alcohol for underage individuals. Primary prevention programs that have used exclusively educational approaches have received mixed results. Increasing effectiveness has been associated with prevention programs that have utilized a multi-component approach and have included educational initiatives with environmental changes.

A longitudinal analysis of alcohol outlet density and domestic violence

AIMS

A small number of studies have identified a positive relationship between alcohol outlet density and domestic violence. These studies have all been based on cross-sectional data and have been limited to the assessment of ecological correlations between outlet density and domestic violence rates. This study provides the first longitudinal examination of this relationship.

DESIGN

Cross-sectional time-series using aggregated data from small areas. The relationships between alcohol outlet density and domestic violence were assessed over time using a fixed-effects model. Controls for the spatial autocorrelation of the data were included in the model.

SETTING

The study uses data for 186 postcodes from within the metropolitan area of Melbourne, Australia for the years 1996 to 2005.

MEASURES

Alcohol outlet density measures for three different types of outlets (hotel/pub, packaged liquor, on-premise) were derived from liquor licensing records and domestic violence rates were calculated from police-recorded crime data, based on the victim's postcode.

FINDINGS

Alcohol outlet density was associated significantly with rates of domestic violence, over time. All three licence categories were positively associated with domestic violence rates, with small effects for general (pub) and on-premise licences and a large effect for packaged liquor licences.

CONCLUSIONS

In Melbourne, the density of liquor licences is positively associated with rates of domestic violence over time. The effects were particularly large for packaged liquor outlets, suggesting a need for licensing policies that pay more attention to o off-premise alcohol availability.

Impact of a new gender-specific definition for binge drinking on prevalence estimates for women

BACKGROUND

Binge drinking accounts for more than half of the 79,000 deaths due to excessive drinking in the U.S. each year. In 2006, the Behavioral Risk Factor Surveillance System (BRFSS) lowered the threshold for defining binge drinking among women from ≥5 drinks to ≥4 drinks per occasion, in accordance with national recommendations.

PURPOSE

To assess changes in binge-drinking prevalence among women.

METHODS

The relative and absolute change in binge drinking among U.S. adult women was assessed using pooled BRFSS data from the 2 years before (2004-2005) and after (2006-2007) the implementation of the new gender-specific definition. Analyses were conducted in 2008-2009.

RESULTS

Binge-drinking prevalence among women increased 2.6 percentage points (from 7.3% in 2004-2005 to 9.9% in 2006-2007), a 35.6% relative increase. The percentage of women who reported consuming exactly 4 drinks in 2006 (3.6%) was similar to the increase in the prevalence of binge drinking among women that was observed from 2005 to 2006 (absolute change=2.9 percentage points).

CONCLUSIONS

The new gender-specific definition of binge drinking significantly increased the identification of women drinking at dangerous levels. The change in prevalence among women was primarily due to the change in the definition and not to actual changes in drinking behavior. The new gender-specific definition of binge drinking can increase the usefulness of this measure for public health surveillance and support the planning and implementation of effective prevention strategies (e.g., increasing alcohol excise taxes).

The effect of tobacco outlet density and proximity on smoking cessation

OBJECTIVES

We examined the influence of tobacco outlet density and residential proximity to tobacco outlets on continuous smoking abstinence 6 months after a quit attempt.

METHODS

We used continuation ratio logit models to examine the relationships of tobacco outlet density and tobacco outlet proximity with biochemically verified continuous abstinence across weeks 1, 2, 4, and 26 after quitting among 414 adult smokers from Houston, Texas (33% non-Latino White, 34% non-Latino Black, and 33% Latino). Analyses controlled for age, race/ethnicity, partner status, education, gender, employment status, prequit smoking rate, and the number of years smoked.

RESULTS

Residential proximity to tobacco outlets, but not tobacco outlet density, provided unique information in the prediction of long-term, continuous abstinence from smoking during a specific quit attempt. Participants residing less than 250 meters (P = .01) or less than 500 meters (P = .04) from the closest tobacco outlet were less likely to be abstinent than were those living 250 meters or farther or 500 meters or farther, respectively, from outlets.

CONCLUSIONS

Because residential proximity to tobacco outlets influences smoking cessation, zoning restrictions to limit tobacco sales in residential areas may complement existing efforts to reduce tobacco use.
