The impact of spatial and temporal availability of alcohol on its consumption and related harms: a critical review in the context of UK licensing policies

Does geographic availability of alcohol influence drinking in adolescents? A systematic review of literature associations

BACKGROUND

The role of alcohol geographic availability in influencing adolescent drinking has been debated. However, clear literature consensus has not been reached.

OBJECTIVE

To provide a systematic review of the associations between geographic availability of alcohol outlets measured through different methodologies and drinking outcomes in adolescents.

METHODS

We conducted a systematic search (PubMed/SCOPUS/Web of Science) for articles exploring associations between alcohol availability and adolescent drinking before 2023. Original articles written in English that evaluated adolescent populations (10-19 years old), included at least one quantitative alcohol consumption outcome and its relationship with geographic availability of alcohol, and declared no conflicts of interest were selected for the review. A quality assessment of the selected articles was made using the Newcastle-Ottawa Scale and descriptive analyses were carried out to summarize results.

RESULTS

Thirty-one articles were reviewed (19 cross-sectional and 12 longitudinal studies), which included a total of 507336 participants. Alcohol availability was positively related to drinking prevalence and risky patterns in 53.3% and 60.5% of associations, respectively. Individual-level covariates, the type of alcohol outlets measured and the different methodological approaches to measure outlet density were related to differences in the direction and magnitude of these associations.

CONCLUSION

Just over half of the studies in this review demonstrate a positive association between alcohol availability and adolescent alcohol consumption with no negative associations reported. The review highlights the mix of methodological approaches that are used, which made it difficult to conduct joint analyses. Additional research is needed to explore the appropriateness, effectiveness and reliability of these methods within various contexts.

Alcohol outlet density and adolescent drinking behaviors in Thailand, 2007-2017: A spatiotemporal mixed model analysis

This study aimed to explore the relationship between alcohol outlet density and the proportion of alcohol consumption among Thai adolescents. We utilized the alcohol consumption data from the 2007, 2011, and 2017 Tobacco and Alcohol Consumption Survey in Thailand. We analyzed the relationships between alcohol sales license figures and consumption behavior using a spatiotemporal mixed model. Our data had two levels. The upper (provincial) level featured alcohol sales license density (spatial effect), the years of survey (temporal effect), and the social deprivation index. The lower (individual) level included the demographic data of the adolescents. A total of 9,566 Thai adolescents participated in this study, based on surveys conducted in 2007 (n = 4,731), 2011 (n = 3,466), and 2017 (n = 1,369). The density of alcohol sales licenses increased the odds for the one-year current drinker category (odds ratio [OR] = 1.08, 95% confidence interval [CI], 1.04-1.45), especially in male adolescents (OR = 1.09, 95% CI, 1.04-1.14). Furthermore, it increased the odds for the heavy episodic drinker category for female adolescents (OR = 1.23, 95% CI, 1.05-1.44). Increased alcohol sales licenses are associated with higher alcohol consumption among Thai adolescents. This highlights the need for government organizations to develop and apply strategies to reduce the number of licenses for the sale of alcohol.

Is alcohol outlet availability associated with binge drinking in Canadian young adults? Findings from British Columbia and Quebec

OBJECTIVES

Alcohol availability is associated with alcohol consumption and related harms, but there is less evidence on associations with heavy episodic drinking (HED), a drinking pattern prevalent among young adults. This study aimed to assess the associations between alcohol availability and HED among young Canadians.

METHODS

We used a population-based sample of Canadian urban-dwelling young adult drinkers (18‒29 years) from the cross-sectional Canadian Community Health Survey (CCHS; cycles 2015‒2019). We linked data from CCHS respondents in British Columbia and Quebec with two measures of alcohol availability for both offsite and onsite outlets: density (AOD) and accessibility (SAI) within dissemination areas (N = 1,067,747). We used logistic regression to estimate the associations between alcohol availability and monthly HED, adjusting for covariates.

RESULTS

The associations between availability and HED differed by province, and availability measure. In British Columbia, offsite and onsite accessibility using SAI was inversely associated with HED. For example, living in neighbourhoods with medium alcohol accessibility (as compared to low) was significantly associated with reduced odds of HED (offsite OR = 0.33, 95% CI 0.17‒0.64; onsite OR = 0.49, 95% CI 0.27‒0.89). In Quebec, offsite availability was positively associated with HED using SAI (although not statistically significant) while no clear trend was seen for onsite availability.

CONCLUSION

Results were consistent with previous evidence. Restricting spatial availability of alcohol remains an important public health strategy for decreasing the ease/convenience of access. Understanding why patterns of availability and drinking differ across regions could inform regionally tailored policies.

Reducing alcohol harms whilst minimising impact on hospitality businesses: 'Sweetspot' policy options

BACKGROUND

During COVID-19, hospitality businesses (e.g. bars, restaurants) were closed/restricted whilst off-sales of alcohol increased, with health consequences. Post-covid, governments face lobbying to support such businesses, but many health services remain under pressure. We appraised 'sweetspot' policy options: those with potential to benefit public services and health, whilst avoiding or minimising negative impact on the hospitality sector.

METHODS

We conducted rapid non-systematic evidence reviews using index papers, citation searches and team knowledge to summarise the literature relating to four possible 'sweetspot' policy areas: pricing interventions (9 systematic reviews (SR); 14 papers/reports); regulation of online sales (1 SR; 1 paper); place-shaping (2 SRs; 18 papers/reports); and violence reduction initiatives (9 SRs; 24 papers/reports); and led two expert workshops (n = 11).

RESULTS

Interventions that raise the price of cheaper shop-bought alcohol appear promising as 'sweetspot' policies; any impact on hospitality is likely small and potentially positive. Restrictions on online sales such as speed or timing of delivery may reduce harm and diversion of consumption from on-trade to home settings. Place-shaping is not well-supported by evidence and experts were sceptical. Reduced late-night trading hours likely reduce violence; evidence of impact on hospitality is scant. Other violence reduction initiatives may modestly reduce harms whilst supporting hospitality, but require resources to deliver multiple measures simultaneously in partnership.

CONCLUSIONS

Available evidence and expert views point to regulation of pricing and online sales as having greatest potential as 'sweetspot' alcohol policies, reducing alcohol harm whilst minimising negative impact on hospitality businesses.

Evaluating the impact of local alcohol licensing decisions on outcomes for the community: a systematic review

Background

International evidence reviews suggest that reducing the availability of alcohol positively impacts both levels of alcohol consumption and associated harms. To understand the impact of recent changes to alcohol licensing and public health in the UK, this review aimed to identify and synthesise quantitative research evidence on the impact of local alcohol licensing decisions on the health and well-being of the community.

Methods

We searched peer-reviewed articles and grey literature for UK studies. We extracted and tabulated key data from the included papers and appraised study quality. We included topic expert and public consultation to confirm the scope of the evidence synthesis and suggest evidence for inclusion. We synthesised narratively and made recommendations based on our findings.

Results

We identified a small volume (seven papers) of evidence regarding the health (and related) impacts of local alcohol licensing decision undertaken in the UK local authorities. The evidence we identified did not demonstrate a consistent or sustained association between local interventions and health or crime outcomes downstream. This was despite relatively sophisticated study designs using a range of available data sources and some longer-term analysis.

Conclusion

Given that the impacts of local licensing decisions are currently limited, greater regulatory powers are needed if local licensing interventions are to be an effective public health interventions to reduce alcohol-related harms.

Factors influencing public health engagement in alcohol licensing in England and Scotland including legal and structural differences: comparative interview analysis

Background

Greater availability of alcohol is associated with higher consumption and harms. The legal systems, by which premises are licensed to sell alcohol in England and Scotland, differ in several ways. The 'Exploring the impact of alcohol licensing in England and Scotland' study measured public health team activity regarding alcohol licensing from 2012 to 2019 and identified seven differences between England and Scotland in the timing and type of activities undertaken.

Objectives

To qualitatively describe the seven previously identified differences between Scotland and England in public health approaches to alcohol licensing, and to examine, from the perspective of public health professionals, what factors may explain these differences.

Methods

Ninety-four interviews were conducted with 52 professionals from 14 English and 6 Scottish public health teams selected for diversity who had been actively engaging with alcohol licensing. Interviews focused primarily on the nature of their engagement (n = 66) and their rationale for the approaches taken (n = 28). Interview data were analysed thematically using NVivo. Findings were constructed by discussion across the research team, to describe and explain the differences in practice found.

Findings

Diverse legal, practical and other factors appeared to explain the seven differences. (1) Earlier engagement in licensing by Scottish public health teams in 2012-3 may have arisen from differences in the timing of legislative changes giving public health a statutory role and support from Alcohol Focus Scotland. (2) Public Health England provided significant support from 2014 in England, contributing to an increase in activity from that point. (3) Renewals of statements of licensing policy were required more frequently in Scotland and at the same time for all Licensing Boards, probably explaining greater focus on policy in Scotland. (4) Organisational structures in Scotland, with public health stakeholders spread across several organisations, likely explained greater involvement of senior leaders there. (5) Without a public health objective for licensing, English public health teams felt less confident about making objections to licence applications without other stakeholders such as the police, and instead commonly negotiated conditions on licences with applicants. In contrast, Scottish public health teams felt any direct contact with applicants was inappropriate due to conflicts of interest. (6) With the public health objective in Scotland, public health teams there were more active in making independent objections to licence applications. Further in Scotland, licensing committee meetings are held to consider all new applications regardless of whether objections have been submitted; unlike in England where there was a greater incentive to resolve objections, because then a meeting was not required. (7) Finally, Scottish public health teams involved the public more in licensing process, partly because of statutory licensing forums there.

Conclusions

The alcohol premises licensing systems in England and Scotland differ in important ways including and beyond the lack of a public health objective for licensing in England. These and other differences, including support of national and local bodies, have shaped opportunities for, and the nature of, public health engagement. Further research could examine the relative success of the approaches taken by public health teams and how temporary increases in availability are handled in the two licensing systems.

Public health engagement in alcohol licensing in England and Scotland: the ExILEnS mixed-method, natural experiment evaluation

Background

International systematic reviews suggest an association between alcohol availability and increased alcohol-related harms. Alcohol availability is regulated through separate locally administered licensing systems in England and Scotland, in which local public health teams have a statutory role. The system in Scotland includes a public health objective for licensing. Public health teams engage to varying degrees in licensing matters but no previous study has sought to objectively characterise and measure their activity, examine their effectiveness, or compare practices between Scotland and England.

Aim

To critically assess the impact and mechanisms of impact of public health team engagement in alcohol premises licensing on alcohol-related harms in England and Scotland.

Methods

We recruited 39 diverse public health teams in England (n = 27) and Scotland (n = 12). Public health teams more active in licensing were recruited first and then matched to lower-activity public health teams. Using structured interviews (n = 66), documentation analysis, and expert consultation, we developed and applied the Public Health Engagement In Alcohol Licensing (PHIAL) measure to quantify six-monthly activity levels from 2012 to 2019. Time series of PHIAL scores, and health and crime outcomes for each area, were analysed using multivariable negative binomial mixed-effects models to assess correlations between outcome and exposure, with 18-month average PHIAL score as the primary exposure metric. In-depth interviews (n = 53) and a workshop (n = 10) explored public health team approaches and potential mechanisms of impact of alcohol availability interventions with public health team members and licensing stakeholders (local authority licensing officers, managers and lawyers/clerks, police staff with a licensing remit, local elected representatives).

Findings

Nineteen public health team activity types were assessed in six categories: (1) staffing; (2) reviewing and (3) responding to licence applications; (4) data usage; (5) influencing licensing stakeholders/policy; and (6) public involvement. Usage and intensity of activities and overall approaches varied within and between areas over time, including between Scotland and England. The latter variation could be explained by legal, structural and philosophical differences, including Scotland's public health objective. This objective was felt to legitimise public health considerations and the use of public health data within licensing. Quantitative analysis showed no clear evidence of association between level of public health team activity and the health or crime outcomes examined, using the primary exposure or other metrics (neither change in, nor cumulative, PHIAL scores). Qualitative data suggested that public health team input was valued by many licensing stakeholders, and that alcohol availability may lead to harms by affecting the accessibility, visibility and norms of alcohol consumption, but that the licensing systems have limited power to act in the interests of public health.

Conclusions

This study provides no evidence that public health team engagement in local licensing matters was associated with measurable downstream reductions in crime or health harms, in the short term, or over a 7-year follow-up period. The extensive qualitative data suggest that public health team engagement is valued and appears to be slowly reorienting the licensing system to better address health (and other) harms, especially in Scotland, but this will take time. A rise in home drinking, alcohol deliveries, and the inherent inability of the licensing system to reduce - or in the case of online sales, to contain - availability, may explain the null findings and will continue to limit the potential of these licensing systems to address alcohol-related harms.

Future work

Further analysis could consider the relative success of different public health team approaches in terms of changing alcohol availability and retailing. A key gap relates to the nature and impact of online availability on alcohol consumption, harms and inequalities, alongside development and study of relevant policy options. A national approach to licensing data and oversight would greatly facilitate future studies and public health input to licensing.

Limitations

Our interview data and therefore PHIAL scores may be limited by recall bias where documentary evidence of public health activity was not available, and by possible variability in grading of such activity, though steps were taken to minimise both. The analyses would have benefited from additional data on licensing policies and environmental changes that might have affected availability or harms in the study areas.

The study was registered with the Research Registry (researchregistry6162) on 26 October 2020. The study protocol was published in BMC Medical Research Methodology on 6 November 2018.

"Availability is the poor cousin of marketing and pricing": qualitative study of stakeholders' views on policy priorities around tobacco and alcohol availability

Background

Reducing alcohol and tobacco availability is one potential way to reduce harm from these unhealthy commodities. This study explores key stakeholders' views in relation to policy priorities and considerations for both alcohol and tobacco availability.

Methods

We conducted semi-structured interviews with 14 stakeholders from alcohol and/or tobacco third sector organizations, government, public health and licensing in Scotland. Interviews explored their views on alcohol/tobacco availability, including its place in the policy landscape and experiences in gaining support for policies. Data were analyzed using thematic analysis.

Results

Stakeholders believed that alcohol and tobacco availability have not received as much policy attention as pricing and marketing. Stakeholders highlighted the importance of public support and having sufficient evidence to inform policy. Key considerations for future policies include: drawing on lessons from tobacco control policies to address alcohol availability, considering different aspects of availability (especially online availability), ensuring policies reflect their local context, considering the impact of policies on children, and managing retailers' involvement in the policy process.

Conclusion

This study highlights key considerations for policies to address alcohol and tobacco availability. There is a need for more research to consider retailers' views and provide greater detail on specific policy suggestions.

A statewide study of disparities in local policies and tobacco, vape, and cannabis retail environments

The current study: (1) assesses sociodemographic disparities in local policies related to tobacco and cannabis retail, and (2) examines the cross-sectional association between policy strength and retailer densities of tobacco, e-cigarette (vape), and cannabis retailers within California cities and county unincorporated areas (N = 539). We combined (a) American Community Survey data (2019 5-year estimates), (b) 2018 tobacco, vape, and cannabis retailer locations from a commercial data provider, (c) 2017 tobacco and vape retail environment policy data from American Lung Association, and (d) 2018 cannabis policy data from California Cannabis Local Laws Database. Conditional autoregressive models examined policy strength associations with sociodemographic composition and retailer density in California jurisdictions. Jurisdictions with larger percentages of Black and foreign-born residents had stronger tobacco and vape policies. For cannabis policy, only income had a small, significant positive association with policy strength. Contrary to hypothesis, tobacco/vape policies were not significantly associated with retailer density, but cannabis policy strength was associated with lower cannabis retailer density (relative rate = 0.58, 95% Uncertainty Interval 0.47-0.70)-this effect was completely driven by storefront bans. Thus, storefront cannabis bans were the only policy studied that was associated with lower cannabis retailer density. Further research is needed to understand policies and disparities in retail environments for tobacco, vape, and cannabis, including data on the prospective association between policy implementation and subsequent retailer density, and the role of enforcement.

Can alcohol policy prevent harms to women and children from men's alcohol consumption? An overview of existing literature and suggested ways forward

The World Health Organization's list of cost-effective alcohol control policies is a widely-used resource that highlights strategies to address alcohol-related harms. However, there is more evidence on how recommended policies impact harms to people who drink alcohol-such as physical health problems caused by heavy alcohol use-than on secondhand harms inflicted on someone other than the person drinking alcohol, i.e., alcohol's harms to others. In this essay, we describe evidence of impacts of alcohol policy on harms to women and children resulting from men's alcohol consumption, as well as options for making policies more relevant for reducing intimate partner violence and child abuse. We begin with an overview of harms to women and children resulting from men's alcohol consumption and review cost-effective alcohol policies with potential to reduce these harms based on likely mechanisms of action. Next, we present a rapid review of reviews to describe existing evidence of impacts of these policies on the outcomes of physical violence, sexual violence, and child abuse and neglect. We found little evidence of systematic evaluation of impacts of these important alcohol policies on harms to women and children. Thus, we advocate for increased attention in evaluation research to the impacts of alcohol policies on harms experienced by women and children who are exposed to men who drink alcohol. We also argue for more consideration of a broader range of policies and interventions to reduce these specific types of harm. Finally, we present a conceptual model illustrating how alcohol policies may be supplemented with other interventions specifically tailored to reduce alcohol-related harms commonly experienced by women and children as a result of men's alcohol use.

Mechanisms of impact of alcohol availability interventions from the perspective of 63 diverse alcohol licensing stakeholders: a qualitative interview study

Aims

Interventions restricting temporal and spatial availability of alcohol are associated with reduced harm, but the pathways by which specific interventions have impact are poorly understood. We examined mechanisms of impact from the perspective of diverse licensing stakeholders.

Methods

Fifty-three in-depth interviews were conducted with licensing stakeholders (from public health teams [PHTs], police, local authority licensing teams and lawyers, and alcohol premises licensing committees) from 20 local government areas. Interviewees were recruited as part of the Exploring the impact of alcohol licensing in England and Scotland (ExILEnS) study. Data were analyzed thematically and preliminary themes/subthemes were discussed during online groups with a different sample of public health and licensing professionals (n = 10).

Findings

Most interviewees struggled to articulate how availability interventions might lead to changes in alcohol consumption or harms. Five overarching mechanisms were identified: access, visibility, premises and area-level norms, affordability, and management of the night-time economy, with specific pathways identified for certain subgroups/premises types. The mechanisms by which alcohol availability interventions may impact on alcohol consumption and harms are diverse, but were poorly understood.

Conclusions

These findings will inform licensing and availability policy and advocacy, highlighting the need for further scrutiny of the evidence underpinning identified mechanisms, and primary research to address knowledge gaps.

Reducing alcohol use through alcohol control policies in the general population and population subgroups: a systematic review and meta-analysis

We estimate the effects of alcohol taxation, minimum unit pricing (MUP), and restricted temporal availability on overall alcohol consumption and review their differential impact across sociodemographic groups. Web of Science, Medline, PsycInfo, Embase, and EconLit were searched on 08/12/2022 and 09/26/2022 for studies on newly introduced or changed alcohol policies published between 2000 and 2022 (Prospero registration: CRD42022339791). We combined data using random-effects meta-analyses. Risk of bias was assessed using the Newcastle-Ottawa Scale. Of 1887 reports, 36 were eligible. Doubling alcohol taxes or introducing MUP (Int$ 0.90/10 g of pure alcohol) reduced consumption by 10% (for taxation: 95% prediction intervals [PI]: -18.5%, -1.2%; for MUP: 95% PI: -28.2%, 5.8%), restricting alcohol sales by one day a week reduced consumption by 3.6% (95% PI: -7.2%, -0.1%). Substantial between-study heterogeneity contributes to high levels of uncertainty and must be considered in interpretation. Pricing policies resulted in greater consumption changes among low-income alcohol users, while results were inconclusive for other socioeconomic indicators, gender, and racial and ethnic groups. Research is needed on the differential impact of alcohol policies, particularly for groups bearing a disproportionate alcohol-attributable health burden.

Behavioral economics indices predict alcohol use and consequences in young men at 4-year follow-up

BACKGROUND AND AIMS

The alcohol purchase task (APT), which presents a scenario and asks participants how many drinks they would purchase and consume at different prices, generates indices of alcohol reward value that have shown robust associations with alcohol-related outcomes in numerous studies. The aim was to test its prospective validity at 4-year follow-up.

DESIGN

Prospective cohort study.

SETTING

General population sample of young Swiss men.

PARTICIPANTS

A total of 4594 Swiss young men (median age = 21, 25th - 75th quartiles = 20.5 - 21.5) completed baseline questionnaires; among those, 4214 (91.7%) were successfully followed-up 4 years later.

MEASUREMENTS

Alcohol reward value parameters (i.e. intensity, the planned consumption when drinks are free; breakpoint, the price at which consumption would be suppressed; O_max , the maximum alcohol expenditure; P_max , the price associated with O_max ; and elasticity, the relative change in alcohol consumption as a function of the relative change in price) were derived from the APT at baseline and used to predict self-reported weekly drinking amount, monthly binge drinking, alcohol-related consequences and DSM-5 alcohol use disorder criteria.

FINDINGS

Regression analyses, adjusting for the baseline alcohol measure, age, linguistic region and socio-economic indicators showed that intensity, breakpoint, O_max and elasticity significantly predicted all tested outcomes in the expected direction (e.g. standardized incidence rate ratio [95% confidence interval] = 1.11 [1.07-1.15], 1.07 [1.03-1.10], 1.08 [1.04-1.11], and 0.92 [0.89-0.95], respectively, for weekly drinking amount, all P < 0.001). P_max did not significantly predict any outcomes. Non-adjusted correlations, baseline adjusted regression and ancillary analyses using (1) latent alcohol variables, (2) multiple imputation for missing data and (3) replications in training and testing subsamples to evaluate predictive accuracy provided consistent findings.

CONCLUSIONS

The alcohol purchase task demand curve measures of alcohol reward value are useful in characterizing alcohol-related risk in young men and have long-term predictive utility.

Inequalities in children's exposure to alcohol outlets in Scotland: a GPS study

BACKGROUND

Alcohol use is a leading cause of harm in young people and increases the risk of alcohol dependence in adulthood. Alcohol use is also a key driver of rising health inequalities. Quantifying inequalities in exposure to alcohol outlets within the activity spaces of pre-adolescent children-a vulnerable, formative development stage-may help understand alcohol use in later life.

METHODS

GPS data were collected from a nationally representative sample of 10-and-11-year-old children (n = 688, 55% female). The proportion of children, and the proportion of each child's GPS, exposed to alcohol outlets was compared across area-level income-deprivation quintiles, along with the relative proportion of exposure occurring within 500 m of each child's home and school.

RESULTS

Off-sales alcohol outlets accounted for 47% of children's exposure, which was higher than expected given their availability (31% of alcohol outlets). The proportion of children exposed to alcohol outlets did not differ by area deprivation. However, the proportion of time children were exposed showed stark inequalities. Children living in the most deprived areas were almost five times more likely to be exposed to off-sales alcohol outlets than children in the least deprived areas (OR 4.83, 3.04-7.66; P < 0.001), and almost three times more likely to be exposed to on-sales alcohol outlets (OR 2.86, 1.11-7.43; P = 0.03). Children in deprived areas experienced 31% of their exposure to off-sales outlets within 500 m of their homes compared to 7% for children from less deprived areas. Children from all areas received 22-32% of their exposure within 500 m of schools, but the proportion of this from off-sales outlets increased with area deprivation.

CONCLUSIONS

Children have little control over what they are exposed to, so policies that reduce inequities in alcohol availability should be prioritised to ensure that all children have the opportunity to lead healthy lives.

Framings of risk and responsibility in newsprint media coverage of alcohol licensing regulations during the COVID-19 pandemic in England

INTRODUCTION

Licensing is recognised as a World Health Organization (WHO) 'best buy' for reducing alcohol harms. In response to the 2020 COVID-19 outbreak, many countries-imposed restrictions on outlets selling alcohol to reduce virus transmission. In England, while shops selling alcohol were deemed 'essential', multiple restrictions were imposed on licenced outlets such as pubs and bars. Media reporting of licensing restrictions during the pandemic might have shaped public discourses of alcohol risks and responsibilities.

METHODS

This study aimed to understand how alcohol licensing changes in England were framed in newsprint media. Two hundred and fifty-three relevant articles from UK newsprint publications were identified through the Nexis database, published within six time points between March and December 2020 reflecting key changes to licencing in England. Thematic analysis, drawing on framing theory, was conducted to identify 'problems' framed in the reporting of these changes.

RESULTS

Four dominant framings were identified: (i) licensed premises as 'risky' spaces; (ii) problematic drinking practices; (iii) problematic policy responses; and (iv) 'victimisation' of licensed premises. The presence of these framings shifted across the reporting period, but consistently, social disorder was constructed as a key risk relating to licensing changes over health harms from alcohol consumption.

DISCUSSION AND CONCLUSIONS

The analysis shows newsprint media reproduced narratives of 'inevitable' drinking culture and social disorder, but also emphasised expectations for evidence-based policy-making, in the context of licensing during the pandemic. Discourses of dissatisfaction with licensing decisions suggests potential for public health advocacy to push for licensing change to reduce alcohol health harms, in England and internationally.

Impact of public health team engagement in alcohol licensing on health and crime outcomes in England and Scotland: A comparative timeseries study between 2012 and 2019

Background

Public health teams (PHTs) in England and Scotland engage to varying degrees in local alcohol licensing systems to try to reduce alcohol-related harms. No previous quantitative evidence is available on the effectiveness of this engagement. We aimed to quantify the effects of PHT engagement in alcohol licensing on selected health and crime outcomes.

Methods

39 PHTs in England (n = 27) and Scotland (n = 12) were recruited (of 40 contacted) for diversity in licensing engagement level and region, with higher activity areas matched to lower activity areas. Each PHT's engagement in licensing for each 6 month period from April 2012 to March 2019 was quantified using a new measure (PHIAL) developed using structured interviews, documentary analyses, and expert consultation. Outcomes examined were ambulance callouts, alcohol-related hospital admissions, alcohol-related and alcohol-specific mortality and violent, sexual and public order offences. Timeseries were analysed using multivariable negative binomial mixed-effects models. Correlations were assessed between each outcome and 18-month average PHIAL score (primary metric), cumulative PHIAL scores and change in PHIAL scores. Additionally, 6-month lagged correlations were also assessed.

Findings

There was no clear evidence of any associations between the primary exposure metric and the public health or crime outcomes examined, nor between cumulative PHIAL scores or change in PHIAL score and any outcomes. There were no significant associations in England or Scotland when analysed separately or between outcomes and lagged exposure metrics.

Interpretation

There is no clear evidence that allocating PHT resources to engaging in alcohol licensing is associated with downstream reductions in alcohol-related health harms or crimes, in the short term or over a seven year follow-up period. Such engagement likely has benefits in shaping the licensing system to take account of health issues longer term, but as current systems cannot reduce alcohol availability or contain online sales, their potential benefits are somewhat constrained.

Addressing alcohol-related harms in the local night-time economy: a qualitative process evaluation from a complex systems perspective

OBJECTIVES

English local authorities (LAs) are interested in reducing alcohol-related harms and may use discretionary powers such as the Late Night Levy (LNL) to do so. This study aims to describe how system stakeholders hypothesise the levy may generate changes and to explore how the system, its actors and the intervention adapt and co-evolve over time.

DESIGN

A process evaluation from a complex systems perspective, using qualitative methods.

SETTING

A London LA with high densities of residential and commercial properties, which implemented the LNL in 2014.

PARTICIPANTS

Data were generated through interviews with LNL implementers and alcohol consumers, observations in bars and during LNL patrols and documentary review.

INTERVENTION

The LNL allows LAs to charge late-night alcohol retailers an annual fee (£299-£4440) to manage and police the night-time economy (NTE).

RESULTS

When the LNL was being considered, stakeholders from different interest groups advanced diverse opinions about its likely impacts while rarely referencing supporting research evidence. Proponents of the levy argued it could reduce crime and anti-social behaviour by providing additional funds to police and manage the NTE. Critics of the levy hypothesised adverse consequences linked to claims that the intervention would force venues to vary their hours or close, cluster closing times, reduce NTE diversity and undermine public-private partnerships. In the first 2 years, levy-funded patrols developed relationships with the licensed trade and the public. The LNL did not undermine public-private partnerships and while some premises varied their hours, these changes did not undermine the intervention's viability, nor significantly cluster venue closing times, nor obviously damage the area's reputation for having a diverse NTE.

CONCLUSIONS

This study applies a framework for process evaluation from a complex systems perspective. The evaluation could be extended to measure alcohol-related outcomes and to consider the interplay between the national and local systems.

How public health teams navigate their different roles in alcohol premises licensing: ExILEnS multistakeholder interview findings

Background

In England and Scotland, local governments regulate the sale of alcohol by awarding licences to premises to permit the sale of alcohol for consumption on or off the premises, under certain conditions; without such a licence, alcohol cannot be legally sold. In recent years, many local public health teams have become proactive in engaging with alcohol licensing, encouraging licensing authorities to act in ways intended to improve population health.

Objective

This research aimed to explore and understand the approaches and activities of public health stakeholders (i.e. NHS staff and other public health professionals) in seeking to influence local alcohol licensing policy and decisions, and the views of licensing stakeholders (i.e. licensing officers/managers, police staff with a licensing remit, elected members and licensing lawyers/clerks) on the acceptability and effectiveness of these approaches.

Participants

Local public health teams in England and Scotland were directly informed about this multisite study. Scoping calls were conducted with interested teams to explore their level of activity in alcohol licensing from 2012 across several categories. Twenty local authority areas with public health teams active in licensing matters were recruited purposively in England (n = 14) and Scotland (n = 6) to vary by region and rurality. Fifty-three in-depth telephone interviews (28 with public health stakeholders and 25 with licensing stakeholders outside health, such as local authority licensing teams/lawyers or police) were conducted. Interview transcripts were analysed thematically in NVivo 12 (QSR International, Warrington, UK) using inductive and deductive approaches.

Results

Public health stakeholders’ approaches to engagement varied, falling into three main (and sometimes overlapping) types. (1) Many public health stakeholders in England and all public health stakeholders in Scotland took a ‘challenging’ approach to influencing licensing decisions and policies. Reducing health harms was felt to necessitate a focus on reducing availability and generating longer-term culture change, citing international evidence on the links between availability and alcohol-related harms. Some of these stakeholders viewed this as being a narrow, ‘nanny state’ approach, whereas others welcomed public health expertise and its evidence-based approach and input. (2) Some public health stakeholders favoured a more passive, ‘supportive’ approach, with some reporting that reducing availability was unachievable. They reported that, within the constraints of current licensing systems, alcohol availability may be contained (at least in theory) but cannot be reduced, because existing businesses cannot be closed on availability grounds. In this ‘supportive’ approach, public health stakeholders supplied licensing teams with data on request or waited for guidance from licensing teams on when and how to get involved. Therefore, public health action supported the licensing team in their aim of promoting ‘safe’ and ‘responsible’ retailing of alcohol and/or focused on short-term outcomes other than health, such as crime. (3) Some public health stakeholders favoured a ‘collaborative’ approach in which they worked in close partnership with licensing teams; this could include a focus on containing availability or responsible retail of alcohol, or both.

Conclusions

In engaging with alcohol licensing, public health stakeholders adapted their approaches, sometimes resulting in a diminished focus on public health goals. Sampling did not include lower-activity areas, in which experiences might differ. The extent to which current licensing systems enable achievement of public health goals is questionable and the effectiveness of public health efforts merits quantitative evaluation.

Association between Bar Closing Time, Alcohol Use Disorders and Blood Alcohol Concentration: A Cross-Sectional Observational Study of Nightlife-Goers in Perth, Australia

Introduction and aims: Associations between bar trading hours, a government lever for controlling alcohol availability, nightlife-goer intoxication levels and their likelihood of alcohol use disorder (AUD) have not been explored. We investigated whether: (i) participant AUD was associated with blood alcohol concentration (BAC); and, (ii) any association between AUD and BAC was moderated by participant preferred bar (i.e., venue spent most time at) closing time. Design and methods: A cross-sectional observational study using a sample of nightlife-goers who went out drinking in Perth, Western Australia, on weekends in 2015-16. Participants who reported alcohol use that night and spent most time in a bar (n = 667) completed street intercept surveys including AUDIT-C (n = 459) and provided a breath sample to estimate BAC (n = 651). We used gender-specific multinomial logistic regression models to explore associations between participant AUDIT-C score (1−4, lower risk; 5−7, hazardous; 8−12, active AUD), preferred bar type (standard vs. late closing time based on absence or presence of an extended trading permit) and BAC (male: 0−0.049, 0.05−0.099, ≥0.1 g/100 mL; female: 0−0.049, 0.05−0.079, ≥0.08 g/100 mL). Results: Males with active AUD (RR = 3.31; 95% CI 1.30−8.42; p = 0.01) and females with hazardous/active AUD (RR = 9.75; 95% CI 2.78−34.21; p < 0.001) were both more likely to have high-range BAC than their counterparts typically drinking at lower risk. We also found preferred bar type moderated the association between AUDIT-C score and BAC for some males but no females. Males with active AUD and high-range BAC were less likely to prefer late closing bars than males usually drinking at lower risk and high-range BAC (RR = 0.12; 95% CI 0.02−0.96; p = 0.046). Discussion and conclusions: Our study provides evidence of positive associations between AUD and acute intoxication among nightlife-goers and on the moderating effect of bar closing times among males.

Exploring the implementation of public involvement in local alcohol availability policy: the case of alcohol licensing decision-making in England

BACKGROUND AND AIMS

In 2003, the UK government passed the Licensing Act for England and Wales. The Act provides a framework for regulating alcohol sale, including four licensing objectives with local governments having devolved responsibility for granting licences to sell alcohol. Members of the public can make representations of oppositions to licence applications. Applying the theories of the policy process, we explored the practices employed by licensing authorities when deciding on alcohol licences in situations of conflict between licence applicants and members of the public.

DESIGN

Qualitative study comprising a framework analysis of in-depth semi-structured interviews and application of the theories of institutionalism, the advocacy coalition framework and role of ideas.

SETTING

Eleven local authorities in five regions in England in 2019.

PARTICIPANTS

Purposive sample of 15 licensing officers, licensing subcommittee chairs, public health leads for licensing and police licensing officers.

MEASUREMENTS

The interview schedule included mechanisms of public involvement in licensing, parties involved, the subject of conflicts and how licensing authorities made decisions.

FINDINGS

When members of the public opposed licence applications, licensing authorities employed three key decision-making practices: procedural fairness, partnership working and framing. The normativity of procedural fairness was an important institutional structure within which conflicts were resolved. Licensing authorities also worked in partnership with the involved parties, who often appeared as advocacy coalitions that shared beliefs and advanced specific issues to determine mutually acceptable solutions. At times, licensing authorities framed issues through ideational processes to solve problems.

CONCLUSION

Licensing decision-making under the United Kingdom's Licensing Act for England and Wales appear in many cases to focus on resolution of conflicts between licence applicants and members of the public rather than on promotion of licensing objectives. This raises uncertainty regarding the impact of public involvement on reducing alcohol availability, but ultimately represents a pragmatic process that seeks to restore balance in powers, improve transparency in decision-making and empower communities.

Association between Nightlife Goers' Likelihood of an Alcohol Use Disorder and Their Preferred Bar's Closing Time: A Cross-Sectional Observational Study in Perth, Australia

Introduction and aims: Associations between longer-term alcohol-related conditions and licensed outlet trading hours are not well understood. We investigated the association between nightlife-goers’ likelihood of an alcohol use disorder (AUD) and their preference for bars with special permits to remain open ‘late’ (i.e., spent more time there compared to any other venue) until 2 a.m. or 3 a.m. (Friday; Saturday) or midnight (Sunday) compared to bars with ‘standard’ closing times of midnight (Friday; Saturday) or 10 p.m. (Sunday). Design and methods: A cross-sectional observational study was conducted in four major nightlife areas of Perth, Australia, in 2015–2016. We conducted weekend street intercept surveys outside bars between 8 p.m. and 3 a.m. and screened participants who reported alcohol use prior to the survey and spent more time in a bar than any other venue type (n = 667) regarding their past year drinking pattern using AUDIT-C (n = 459). We used gender-specific logistic regression models to estimate associations between AUDIT-C categories (1–4, low risk; 5–7, hazardous; 8–12, active AUD) and preference for bars with different closing times (late vs. standard). Results: A large proportion of participants were hazardous drinkers or had active AUD (83% males; 65% females), and over half preferred a late to a standard closing bar. We found evidence of a positive association between preference for late closing bars and hazardous drinking females (OR = 3.48; 95% CI 1.47–8.23; p = 0.01), but not for females with active AUD, male hazardous drinkers, nor males with active AUD. Discussion and conclusions: Our study adds new evidence on associations between likelihood of AUD among nightlife-goers and trading hours. With increasing international relaxation of trading hours, evidence that late closing bars may be preferred by hazardous drinking females will be of concern to policymakers wanting to curb alcohol-related harms in the community.

Evaluating the effects of the Licensing Act 2003 on the characteristics of drinking occasions in England and Wales: a theory of change-guided evaluation of a natural experiment

BACKGROUND AND AIMS

The Licensing Act 2003 deregulated trading hours in England and Wales. Previous evaluations have focused upon consumption and harm outcomes, finding mixed results. Several evaluations speculated on the reasons for their results, noting the role of changes in the characteristics of drinking occasions. This study aimed to test proposed mechanisms of effect for the Licensing Act 2003 by evaluating changes in characteristics of drinking occasions. Design, Setting and Participants Interrupted monthly time-series analysis of effects in England and Wales versus a Scottish control series, using 2001-08 data collected via 7-day drinking occasions diaries by the market research company Kantar (n = 89 192 adults aged 18+).

MEASUREMENTS

Outcomes were start- and end-time of each reported occasion; variation in finish time; prevalence of pre-loading, post-loading and late-night drinking; and alcohol consumption (in units).

FINDINGS

After the introduction of the Act, occasions shifted later at night in England and Wales [finish time +11.4 minutes; 95% confidence interval (CI) = 3.6-19.2]. More occasions involved pre-loading in England and Wales relative to Scotland (0.02% increase; 95% CI = 0.01-0.03). There was no evidence of changes in variation in finish time, post-loading, late-night drinking or alcohol consumption.

CONCLUSIONS

The Licensing Act 2003 in England and Wales appears to have had only limited effects on the characteristics of drinking occasions. This may help to explain its lack of substantial impacts on alcohol harms.

What on-line searches tell us about public interest and potential impact on behaviour in response to minimum unit pricing of alcohol in Scotland

AIMS

To investigate whether the introduction of minimum unit pricing (MUP) in Scotland on 1 May 2018 was reflected in changes in the likelihood of alcohol-related queries submitted to an internet search engine, and in particular whether there was any evidence of increased interest in purchasing of alcohol from outside Scotland.

DESIGN

Observational study in which individual queries to the internet Bing search engine for 2018 in Scotland and England were captured and analysed. Fluctuations over time in the likelihood of specific topic searches were examined. The patterns seen in Scotland were contrasted with those in England.

SETTING

Scotland and England.

PARTICIPANTS

People who used the Bing search engine during 2018.

MEASUREMENTS

Numbers of daily queries submitted to Bing in 2018 on eight alcohol-related topics expressed as a proportion of queries on that day on any topic. These daily likelihoods were smoothed using a 14-day moving average for Scotland and England separately.

FINDINGS

There were substantial peaks in queries about MUP itself, cheap sources of alcohol and online alcohol outlets at the time of introduction of MUP in May 2018 in Scotland, but not England. These were relatively short-lived. Queries related to intoxication and alcohol problems did not show a MUP peak, but were appreciably higher in Scotland than in England throughout 2018.

CONCLUSIONS

Analysis of internet search engine queries appears to show that a fraction of people in Scotland may have considered circumventing minimum unit pricing in 2018 by looking for on-line alcohol retailers. The overall higher levels of queries related to alcohol problems in Scotland compared with England mirrors the corresponding differences in alcohol consumption and harms between the countries.

Compliance with a law to reduce alcoholic beverage sales and service in Zacatecas, Mexico

BACKGROUND

Research on the effects of restricting bar opening hours and alcohol sales in middle-income countries is very limited. We assessed compliance with and possible effects of a law enacted in Zacatecas, Mexico on December 30, 2017 and implemented in 2018 and 2019 that established a 2 AM bar closing time and 10 PM cut-off for alcohol sales by off-premises stores.

METHODS

Monthly observations of bars and off-premises stores and alcohol mystery shopping visits from 2018 to early 2020 were conducted to assess compliance with the law. Breath tests were conducted in 2018 and 2019 with samples of pedestrians in the nighttime entertainment districts of Zacatecas and a comparison city (Aguascalientes). Surveys of bar owners/managers and staff, emergency medical personnel (EMP), and police officers were conducted in Zacatecas in 2018 and 2019 to assess awareness and support of the law and possible effects of the law on alcohol-related problems such as violence and injuries.

RESULTS

Monthly observations indicated that a substantial percentage of bars and off-premises package stores did not comply with the law. Pedestrian breath tests in 2018 and 2019 indicated significant reductions in blood alcohol concentration and heavy drinking among pedestrians in Zacatecas from 11 PM to 2 AM compared to Aguascalientes, but not after 2 AM. Surveys of bar owners/managers indicated that most were aware and supportive of the law. EMP surveys indicated reductions in incidents of physical fighting and drunk or injured customers during the annual September fair in Zacatecas.

CONCLUSIONS

This study suggests that restricting bar opening hours and alcohol sales may not result in full compliance by bars and off-premises stores, but may help to reduce excessive alcohol use and related harms in a middle-income country. A more rigorous evaluation with pre-intervention data is needed, however, to fully address this latter question.

A Spatial Analysis of Alcohol Outlet Density Type, Abandoned Properties, and Police Calls on Aggravated Assault Rates in a Northeastern U.S. City

Background: Community-based research and prevention scholarship has shown a growing interest in examining the impact of the ecological structure of neighborhoods on community violence. Ecological structures such as higher numbers of alcohol outlets and abandoned/vacant properties in geographically dense, poor, and socially isolated communities are critically important to consider. Further, disadvantaged urban communities are burdened by greater police presence with limited or no abatement in crime or violence. Purpose: Using Geographic Information Systems (GIS) mapping, spatial analysis techniques, and a negative binomial regression analyses, this study investigated the relationships between alcohol outlet density consisting of license C (i.e., combined on and off premises establishments) and license D (i.e., off premises establishments such as liquor stores), abandoned properties, and police calls to service on aggravated assault rates in a Northeastern United States urban city. Results: Negative binomial regression analysis results showed that license C alcohol outlet density count (IRR = 1.36, 95% CI = 1.08, 2.11), license D alcohol outlet density count (IRR = 1.13, 95% CI = 1.01, 1.30), abandoned property count (IRR = 1.28, 95% CI = 1.01, 2.01), and police call to service counts (IRR = 1.24, 95% CI = 1.01, 1.50) were positively associated with aggravated assault rates. Analyses controlled for census data characteristics. Conclusions: The link between alcohol outlet density and violent crime has been established in public health research. However, this study represents an important contribution in recognizing the unique relationships between license C and license D alcohol outlet density, abandoned properties, and police calls to service with aggravated assaults in an urban neighborhood. Conclusions are drawn for policy and practice.

Close proximity to alcohol outlets is associated with increased crime and hazardous drinking: Pooled nationally representative data from New Zealand

This nationwide study investigated the relationship between proximity to alcohol outlets (off-licence, on-licence, and other-licence) and two adverse outcomes; hazardous drinking and crime (common assault, non-aggravated sexual assault, aggravated sexual assault, and tobacco and liquor offences). After adjustment for important individual- and area-level factors, close proximity to alcohol outlets was associated with increased risk of hazardous drinking, with strong associations for on-licence outlets. Proximity alcohol outlets was also strongly associated with all crime outcomes, often with a dose-response relationship. Nationally representative New Zealand data showed that close proximity to alcohol outlets was associated with increased crime and hazardous drinking.

Looking Back and Moving Forward: The Evolution and Potential Opportunities for the Future of Alcohol Outlet Density Measurement

The literature consistently finds that areas with greater density of alcohol outlets (places that sell alcohol) tend to have higher levels of public health harms. However, conflicting findings arise when researchers drill down to identify the type(s) of alcohol outlets with the strongest associations with harms and the mechanisms that explain these associations. These disagreements could be a result of the outdated methods commonly used to quantify the alcohol environment: counts of the number of outlets in an area. This manuscript reviews the events and ideas that shaped the literature on the physical alcohol environment. It then defines the three main methods used to measure alcohol outlet density, conducts an exploratory factor analysis to explore the constructs underlying each method, and presents a novel conceptual framework that summarizes the three methods, their respective underlying constructs, and the setting(s) in which each may be most appropriate. The framework proposes that counts of alcohol outlets measure availability, proximity to the nearest outlet measures accessibility, and spatial access measures measure access, which comprises both availability and accessibility. We argue that researchers should consider using proximity and spatial access measures when possible and outline how doing so may present opportunities to advance theory and the design and implementation of alcohol outlet zoning regulations. Finally, this manuscript draws on research from other areas of the built environment to suggest opportunities to use novel methods to overcome common hurdles (e.g., separating subtypes of outlets, ecologic designs) and a new challenge on the horizon: home delivery.

Geographic gender differences in traumatic unintentional injury hospitalization and youth drinking

INTRODUCTION

Few studies have used both spatial and non-spatial techniques to the study of alcohol outcomes. The objectives of this study were to identify clusters of traumatic unintentional injury hospitalizations by gender and blood alcohol concentration (BAC), and to determine trends and correlates by BAC levels.

METHODS

State Trauma Registry data capturing unintentional injuries for those aged 10 to 24 hospitalized with negative and positive BAC levels (n = 6233) were analyzed from 2006 to 2015 for all Chicago block groups. Spatial clustering techniques were applied to detect spatial clusters and Generalized Estimating Equations to determine correlates and trends while controlling for correlation within block groups.

RESULTS

Regardless of BAC level, hospitalization rates decreased for all age groups between 2006 to 2010 and 2011 to 2015 from 94.41 to 67.69 per 100,000 population. The decline for males hospitalized with positive BAC was 1.4 times greater than the decline for their female counterparts. Risk factors included being male, black or of a minority race, having no private insurance and living in a disadvantaged neighborhood. Male hospitalization rates clustered among 33 census block groups located in three Chicago Community Areas. No clustering was detected for female patients. Motor vehicle accidents were the leading cause of hospitalization.

CONCLUSIONS

Hospitalizations are decreasing in Chicago, yet the risk is concentrated, with greater decreasing rates among males than females. Spatial approaches can be valuable tools in analyzing substance abuse outcomes, to identify high-risk areas and shifts in risk within a large geographic area.

Public health policies and alcohol-related liver disease

Alcohol-related liver disease (ALD) represents a major public health problem worldwide. According to the World Health Organization, the highest levels of per capita alcohol consumption are observed in countries of the European Region. Alcohol consumption is also alarmingly increasing in developing countries. ALD is one of the main contributors to the burden of alcohol-attributable deaths and disability. In the United States, severe forms of ALD such alcoholic hepatitis have increased in the last decade and in the United Kingdom, three-quarters of liver-related mortality results from alcohol consumption. Besides genetic factors, there is strong evidence that the amount of alcohol consumed plays a major role in the development of advanced ALD. Establishing effective public health policies is therefore mandatory to reduce the burden of ALD. Since the 90s, major public health institutions and governments have developed a variety of policies in order to reduce the harm caused by excessive drinking. These policies encompass multiple factors, from pricing and taxation to advertising regulation. Measures focused on taxation and price regulation have been shown to be the most effective at reducing alcohol-related mortality. However, there are few studies focused on the effect of public policies on ALD. This review article summarises the factors influencing ALD burden and the role of different public health policies.

Access to cannabis retail stores across Canada 6 months following legalization: a descriptive study

BACKGROUND

On Oct. 17, 2018, Canada legalized recreational cannabis with the dual goals of reducing youth use and eliminating the illicit cannabis market. We examined factors associated with access to physical cannabis stores across Canada 6 months following legalization.

METHODS

We extracted the address and operating hours of all legal cannabis stores in Canada from online government and private listings. We conducted a descriptive study examining the association between private/hybrid (mixture of government and private stores) and government-only retail models with 4 measures of physical access to cannabis: store density, weekly hours of operation, median distance to the nearest school and relative availability of cannabis stores between low- and high-income neighbourhoods.

RESULTS

Six months after legalization, there were 260 cannabis retail stores across Canada: 181 privately run stores, 55 government-run stores and 24 stores in the hybrid retail system. Compared to jurisdictions with a government-run model, jurisdictions with a private/hybrid retail model had 49% (95% confidence interval 10%-200%) more stores per capita, retailers were open on average 9.2 more hours per week, and stores were located closer to schools (median 166.7 m). In both retail models, there was over twice the concentration of cannabis stores in neighbourhoods in the lowest income quintile compared to the highest income quintile.

INTERPRETATION

Marked differences in physical access to cannabis retail are emerging between jurisdictions with private/hybrid retail models and those with government-only retail models. Ongoing surveillance including monitoring differences in cannabis use and harms across jurisdictions is needed.

The association between alcohol access and alcohol-attributable emergency department visits in Ontario, Canada

BACKGROUND AND AIMS

The availability of alcohol through retail outlets is associated with alcohol-related harms, but few studies have demonstrated a causal relationship. We investigated the association between alcohol availability and alcohol-attributable emergency department (ED) visits in the province of Ontario during a period of deregulation of controls on the number of alcohol outlets.

DESIGN

Cross-sectional and pre-post design SETTING AND PARTICIPANTS: The study used data from two time-periods: pre-deregulation (2013-14) and post-deregulation (2016-17), to compare rates of ED visits for 513 defined geographic regions in Ontario Canada, called Forward Sortation Areas (FSAs).

MEASUREMENTS

The primary outcome was the age-standardized rates of alcohol-attributable ED visits. We compiled a list of all alcohol retail outlets in Ontario during 2014 and 2017 and matched them to their corresponding FSA. We fitted mixed-effects Poisson regression models to assess: (a) the cross-sectional association between number of outlets and hours of operation and ED visits; and (b) the impact of deregulation on ED visits using a difference-in-difference approach.

FINDINGS

Alcohol-attributed ED visits increased 17.8% over the study period: more than twice the rate of increase for all ED visits. Increased hours of operation and numbers of alcohol outlets within an FSA were positively associated with higher rates of alcohol-attributable ED visits. The increase in ED visits attributable to alcohol was 6% (incident rate ratio = 1.06; 95% confidence interval = 1.04-1.08) greater in FSAs that introduced alcohol sales in grocery stores following deregulation compared with FSAs that did not.

CONCLUSIONS

Deregulation of alcohol sales in Ontario, Canada in 2015 was associated with increased emergency department visits attributable to alcohol.

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

BACKGROUND

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Local Alcohol Policy Implementation in Scotland: Understanding the Role of Accountability within Licensing

Scotland has been ambitious in its policy and legislative efforts to tackle alcohol-related harm, efforts which include the innovative feature of a ‘public health objective’ within local alcohol licensing. However, the persistence of alcohol-related harms and inequalities requires further examination of both the overarching Scottish alcohol strategy and its specific implementation. A qualitative case study was undertaken to explore how alcohol policy is implemented locally in Scotland, with data generated from (i) documentary analysis of 12 relevant policies, legislation, and guidance documents; and (ii) a thematic analysis of semi-structured interviews with 54 alcohol policy implementers in three Scottish localities and nine national-level stakeholders. The data suggest there is a tension between the intentions of licensing legislation and the way it is enacted in practice, and that accountability emerges as an important factor for understanding why this occurs. In particular, there are a lack of accountability mechanisms acting upon Scottish Licensing Boards to ensure they contribute to the public health goals of the Scottish alcohol strategy. From a public health perspective, this has perpetuated a system in which Licensing Boards continue to act with autonomy from the rest of the alcohol policy implementation system, creating a challenge to the achievement of public health goals. Alcohol policy in Scotland is likely to fall short of intended goals as long as the tension between licensing legislation and enacted licensing practices remains.

Alcohol Availability Across Neighborhoods in Ontario Following Alcohol Sales Deregulation, 2013-2017

Objectives. To examine the association between neighborhood socioeconomic status (SES) and alcohol availability before and after deregulation in 2015 of the alcohol market in Ontario, Canada. Methods. We quantified alcohol access by number of alcohol outlets and hours of retail for all 19 964 neighborhoods in Ontario. We used mixed effects regression models to examine the associations between alcohol access and a validated SES index between 2013 and 2017. Results. Following deregulation, the number of alcohol outlets in Ontario increased by 15.0%. Low neighborhood SES was positively associated with increased alcohol access: lower-SES neighborhoods had more alcohol outlets within 1000 meters and were closer to the nearest alcohol outlets. Outlets located in low-SES neighborhoods kept longer hours of operation. Conclusions. We observed a substantial increase in alcohol access in Ontario following deregulation. Access to alcohol was greatest in low-SES neighborhoods and may contribute to established inequities in alcohol harms. Public Health Implications. Placing limits on number of alcohol outlets and the hours of operation in low-SES neighborhoods offers an opportunity to reduce alcohol-related health inequities.

Epidemiology of Alcohol Consumption and Societal Burden of Alcoholism and Alcoholic Liver Disease

Alcohol abuse is a major determinant of public health outcomes. Worldwide data from 2016 indicate that alcohol is the seventh leading risk factor in terms of disability-adjusted life years, an increase of more than 25% from 1990 to 2016. Understanding the epidemiology of alcoholic liver disease, including the regional variations in consumption and public policy, is an area of active research. In countries where the per capita consumption of alcohol decreases, there appears to be an associated decrease in disease burden. Given alcohol's health burden, an increased focus on alcohol control policies is needed.

Treating alcohol-related liver disease from a public health perspective

Herein, we describe the evolving landscape of alcohol-related liver disease (ALD) including the current global burden of disease and cost to working-aged people in terms of death and disability, in addition to the larger spectrum of alcohol-related heath complications and its wider impact on society. We further review the most effective and cost-effective public health policies at both a population and individual level. Currently, abstinence is the only effective treatment for ALD, and yet because the majority of ALD remains undetected in the community abstinence is initiated too late to prevent premature death in the majority of cases. We therefore hope that this review will help inform clinicians of the "public health treatment options" for ALD to encourage engagement with policy makers and promote community-based hepatology as a speciality, expanding our patient cohort to allow early detection, and thereby a reduction in the enormous morbidity and mortality associated with this disease.

Exploring the impact of public health teams on alcohol premises licensing in England and Scotland (ExILEnS): procotol for a mixed methods natural experiment evaluation

BACKGROUND

Recent regulatory changes in the system by which premises are licensed to sell alcohol, have given health representatives a formal role in the process in England and Scotland. The degree to which local public health teams engage with this process varies by locality in both nations, which have different licensing regimes. This study aims to critically assess the impact on alcohol-related harms - and mechanisms - of public health stakeholders' engagement in alcohol premises licensing from 2012 to 2018, comparing local areas with differing types and intensities of engagement, and examining practice in Scotland and England.

METHODS

The study will recruit 20 local authority areas where public health stakeholders have actively engaged with the alcohol premises licensing system (the 'intervention') and match them to a group of 20 lower activity areas using genetic matching. Four work packages are included: (1) Structured interviews and documentary analysis will examine the type and level of intervention activity from 2012 to 2018, creating a novel composite measure of the intensity of such activity and will assess the local licensing system and potential confounding activities over the same period. In-depth interviews with public health, licensing, police and others will explore perceived mechanisms of change, acceptability, and impact. (2) Using longitudinal growth models and time series analyses, the study will evaluate the impact of high and low levels of activity on alcohol-related harms using routine data from baseline 2009 to 2018. (3) Intervention costs, estimated National Health Service cost savings and health gains will be evaluated using the Sheffield Alcohol Policy Model to estimate impact on alcohol consumption and health inequalities. (4) The study will engage public health teams to create a new theory of change for public health involvement in the licensing process using our data. We will share findings with local, national and international stakeholders.

DISCUSSION

This interdisciplinary study examines, for the first time, whether and how public health stakeholders' involvement in alcohol licensing impacts on alcohol harms. Using mixed methods and drawing on complex systems thinking, it will make an important contribution to an expanding literature evaluating interventions not suited to traditional epidemiological research.

Alcohol outlet density and alcohol related hospital admissions in England: a national small-area level ecological study

BACKGROUND AND AIMS

Excessive alcohol consumption has a substantial impact on public health services. A key element determining alcohol availability is alcohol outlet density. This study investigated the relationship between on-trade and off-trade outlets and hospital admission rates in local neighbourhoods.

DESIGN

National small-area level ecological study.

SETTING AND PARTICIPANTS

All 32 482 lower layer super output census areas (LSOAs) in England (42 227 108 million people aged 15+ years). Densities for six outlet categories (outlets within a 1-km radius of residential postcode centroids, averaged for all postcodes within each LSOA) were calculated.

MEASUREMENTS

Main outcome measures were admissions due to acute or chronic conditions wholly or partially attributable to alcohol consumption from 2002/03 to 2013/14.

FINDINGS

There were 1 007 137 admissions wholly, and 2 153 874 admissions partially, attributable to alcohol over 12 years. After adjustment for confounding, higher densities of on-trade outlets (pubs, bars and nightclubs; restaurants licensed to sell alcohol; other on-trade outlets) and convenience stores were associated with higher admission rate ratios for acute and chronic wholly attributable conditions. For acute wholly attributable conditions, admission rate ratios were 13% (95% confidence interval = 11-15%), 9% (7-10%), 12% (10-14%) and 10% (9-12%) higher, respectively, in the highest relative to the lowest density categories by quartile. For chronic wholly attributable conditions, rate ratios were 22% (21-24%), 9% (7-11%), 19% (17-21%) and 7% (6-9%) higher, respectively. Supermarket density was associated with modestly higher acute and chronic admissions but other off-trade outlet density was associated only with higher admissions for chronic wholly attributable conditions. For partially attributable conditions, there were no strong patterns of association with outlet densities.

CONCLUSIONS

In England, higher densities of several categories of alcohol outlets appear to be associated with higher hospital admission rates for conditions wholly attributable to alcohol consumption.

Increasing powers to reject licences to sell alcohol: Impacts on availability, sales and behavioural outcomes from a novel natural experiment evaluation

Excessive alcohol consumption leads to negative health and social impacts at individual and population levels. Interventions that aim to limit the density of alcohol retail premises (including cumulative impact policies (CIPs)) have been associated with decreases in alcohol-related crime and alcohol-related hospital admissions. We evaluated the quantitative impact of introducing a new alcohol licensing policy that included a comprehensive Cumulative Impact Policy (CIP) enforced in seven Cumulative Impact Zones (CIZs) in one English Local Authority in 2013. We used time series analysis to assess immediate and longer term impacts on licensing decisions and intermediate outcomes, including spatial and temporal alcohol availability, crime, alcohol-related ambulance call-outs and on-licence alcohol retail sales across the Local Authority and in CIZs and non-CIZs during the period 2008 to 2016. We found no impact on licence application rates but post-intervention applications involved fewer trading hours. Application approvals declined initially but not over the longer term. Longer term, small reductions in units of alcohol sold in bars (-2060, 95% confidence interval (CI) = -3033, -1087) were observed in areas with more intensive licensing policies ('Cumulative Impact Zones' (CIZs)). Significant initial declines in overall crime rates (CIZs = -12.2%, 95% CI = -18.0%, -6.1%; non-CIZs = -8.0%, 95% CI = -14.0%, -1.6%) were only partially reversed by small, longer term increases. Ambulance callout rates did not change significantly. The intervention was partially successful but a more intensive and sustained implementation may be necessary for longer term benefits.

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 Availability and Onset and Recurrence of Alcohol Use Disorder: Examination in a Longitudinal Cohort with Cosibling Analysis

BACKGROUND

Recent reviews of associations of alcohol availability with alcohol outcomes suggest findings are highly inconsistent and highlight a lack of longitudinal and causal evidence. Effect modification (moderation or statistical interaction), which could contribute to the inconsistent picture in the existing literature, has not been systematically assessed. We examined associations of alcohol availability with onset and recurrence of alcohol use disorder (AUD) using multilevel, longitudinal population data from Sweden and tested hypothesized effect modifiers to identify groups for whom increased alcohol availability may be particularly risky. We also employed cosibling models to assess potential causality for AUD onset by accounting for genetic and shared-environment confounders.

METHODS

Data come from all individuals born in Sweden between 1950 and 1975 who were registered in a residential neighborhood at the end of 2005 (N = 2,633,922). We used Cox proportional hazards models to investigate time to AUD onset and logistic regression to assess the odds of AUD recurrence over an 8-year period.

RESULTS

Living in a neighborhood with at least 1 alcohol outlet of any type was associated with a small increase in the likelihood of developing AUD, with an adjusted hazard ratio (HR) of 1.16 (95% CI: 1.13 to 1.19). Among people with a prior AUD registration, alcohol availability was not significantly associated with recurrence of AUD, with an adjusted odds ratio of 1.02 (95% CI: 1.00 to 1.05). Associations of alcohol availability with AUD onset varied according to sex, age, education, neighborhood deprivation, and urbanicity. HRs from the sibling models were similar to those in the general population models, with an adjusted HR = 1.19 (95% CI: 1.15 to 1.24).

CONCLUSIONS

Effects varied among neighborhood residents, but greater alcohol availability was a risk factor for AUD onset (but not relapse) in all groups examined except women. Cosibling models suggest there may be a causal relationship of greater alcohol availability with adult-onset AUD.

Is proximity to alcohol outlets associated with alcohol consumption and alcohol-related harm in Denmark?

BACKGROUND

This study examined the associations between distance from residence to the nearest alcohol outlet with alcohol consumption as well as with alcohol-related harm.

METHODS

Data on alcohol consumption, alcohol-related harm and sociodemographics were obtained from the 2011 Danish Drug and Alcohol Survey (n = 5133) with respondents aged 15-79 years. The information on distances from residence to the nearest alcohol outlets was obtained from Statistics Denmark. Multiple logistic and linear regressions were used to examine the association between distances to outlets and alcohol consumption whereas alcohol-related harm was analysed using negative binomial regression.

RESULTS

Among women it was found that those living closer to alcohol outlets were more likely to report alcohol-related harm (p < 0.05). This was not true for men. No association was found between distances to outlets and alcohol consumption (volume of drinking and risky single occasion drinking).

CONCLUSIONS

This study found some support for an association between closer distances between place of residence and alcohol outlets and alcohol-related harm for women. Future studies in the Nordic region should continue to examine the association between physical alcohol availability (nearest distance to an outlet and outlet densities) and alcohol consumption as well as alcohol-related problems using different outlet types.
