The families and friends of heavy drinkers: Caught in the cross-fire of policy change?

Is minimum unit pricing for alcohol having the intended effects on alcohol consumption in Scotland?

BACKGROUND AND AIMS

The Scottish Government introduced minimum unit pricing (MUP) for alcohol on 1 May 2018. This means retailers in Scotland cannot sell alcohol to consumers for less than £0.50 per unit (1 UK unit = 8 g ethanol). The Government intended the policy to increase the price of cheap alcohol, cut alcohol consumption overall and particularly among those drinking at hazardous or harmful levels, and ultimately reduce alcohol-related harm. This paper aims to summarise and assess the evidence to date evaluating the impact of MUP on alcohol consumption and related behaviours in Scotland.

ARGUMENT

Evidence from analyses of population-level sales data suggest, all else being equal, MUP reduced the volume of alcohol sold in Scotland by ~ 3.0% to 3.5%, with the largest reductions affecting cider and spirits sales. Analyses of two time series datasets on household-level alcohol purchasing and individual-level alcohol consumption suggest reductions in purchasing and consumption among those drinking at hazardous and harmful levels, but offer conflicting results for those drinking at the most harmful levels. These subgroup analyses are methodologically robust, but the underlying datasets have important limitations as they rely on non-random sampling strategies. Further studies identified no clear evidence of reduced alcohol consumption among those with alcohol dependence or those presenting to emergency departments and sexual health clinics, some evidence of increased financial strain among people with dependence and no evidence of wider negative outcomes arising from changes in alcohol consumption behaviours.

CONCLUSIONS

Minimum unit pricing for alcohol in Scotland has led to reduced consumption, including among heavier drinkers. However, there is uncertainty regarding its impact on those at greatest risk and some limited evidence of negative outcomes, specifically financial strain, among people with alcohol dependence.

Views on minimum unit pricing for alcohol before its introduction among people with alcohol dependence in Scotland: A qualitative interview study

INTRODUCTION

Scotland implemented a minimum price per unit of alcohol (MUP) of £0.50 in May 2018 (1 UK unit = 10 mL/8 g ethanol). Some stakeholders expressed concerns about the policy having potential negative consequences for people with alcohol dependence. This study aimed to investigate anticipated impacts of MUP on people presenting to alcohol treatment services in Scotland before policy implementation.

METHODS

Qualitative interviews were conducted with 21 people with alcohol dependence accessing alcohol treatment services in Scotland between November 2017 and April 2018. Interviews examined respondents' current and anticipated patterns of drinking and spending, effects on their personal life, and their views on potential policy impact. Interview data were thematically analysed using a constant comparison method.

RESULTS

Three key themes were identified: (i) strategies used to manage the cost of alcohol and anticipated responses to MUP; (ii) broader effects of MUP; and (iii) awareness and preparedness for MUP. Respondents expected to be impacted by MUP, particularly those on low incomes and those with more severe dependence symptoms. They anticipated using familiar strategies including borrowing and reprioritising spending to keep alcohol affordable. Some respondents anticipated negative consequences. Respondents were sceptical about the short-term benefits of MUP for current drinkers but felt it might prevent harm for future generations. Respondents had concerns about the capacity of treatment services to meet support needs.

DISCUSSION AND CONCLUSIONS

People with alcohol dependence identified immediate concerns alongside potential long-term benefits of MUP before its introduction. They also had concerns over the preparedness of service providers.

Evaluating the effects of minimum unit pricing in Scotland on the prevalence of harmful drinking: a controlled interrupted time series analysis

OBJECTIVES

In May 2018, the Scottish Government introduced a minimum unit price (MUP) for alcohol of £0.50 (1 UK unit = 8 g ethanol) to reduce alcohol consumption, particularly among people drinking at harmful levels. This study aimed to evaluate MUP's impact on the prevalence of harmful drinking among adults in Scotland.

STUDY DESIGN

This was a controlled interrupted monthly time series analysis of repeat cross-sectional data collected via 1-week drinking diaries from adult drinkers in Scotland (N = 38,674) and Northern England (N = 71,687) between January 2009 and February 2020.

METHODS

The primary outcome was the proportion of drinkers consuming at harmful levels (>50 [men] or >35 [women] units in diary week). The secondary outcomes included the proportion of drinkers consuming at hazardous (≥14-50 [men] or ≥14-35 [women] units) and moderate (<14 units) levels and measures of beverage preferences and drinking patterns. Analyses also examined the prevalence of harmful drinking in key subgroups.

RESULTS

There was no significant change in the proportion of drinkers consuming at harmful levels (β = +0.6 percentage points; 95% confidence interval [CI] = -1.1, +2.3) or moderate levels (β = +1.4 percentage points; 95% confidence interval = -1.1, +3.8) after the introduction of MUP. The proportion consuming at hazardous levels fell significantly by 3.5 percentage points (95% CI = -5.4, -1.7). There were no significant changes in other secondary outcomes or in the subgroup analyses after correction for multiple testing.

CONCLUSIONS

Introducing MUP in Scotland was not associated with reductions in the proportion of drinkers consuming at harmful levels but did reduce the prevalence of hazardous drinking. This adds to previous evidence that MUP reduced overall alcohol consumption in Scotland and consumption among those drinking above moderate levels.
