RESUMO
OBJECTIVE: Inequalities in alcohol-related harm may arise partly from differences in drinking practices between population groups. One under-researched practice associated with harm is consuming alcohol alone. We identify sociodemographic characteristics associated with drinking alone and the occasion-level characteristics associated with occasions when people drink alone. METHOD: A cross-sectional analysis of one-week drinking diaries collected between 2015 and 2019 was conducted using event-level data on 271,738 drinking occasions reported by 83,952 adult drinkers in Great Britain. Our two dependent variables were a binary indicator of reporting at least one solitary drinking occasion in the diary-week at the individual-level and a binary indicator of drinking alone at the occasion-level (event-level). RESULTS: Individual-level characteristics associated with solitary drinking were being a man (OR 1.88, 95%CI [1.80,1.96]), aged over 50 (OR 2.60, 95%CI [2.40,2.81]), not in a relationship (OR 3.39, 95%CI [3.20, 3.59]), living alone (OR 2.51, 95%CI [2.37, 2.66]), and a high-risk drinker (OR 1.54, 95%CI [1.52,1.59]). Occasion-level characteristics associated with solitary drinking were that they were more likely to occur in the off-trade (OR 3.08, 95%CI [2.95,3.21]), Monday-Thursday (OR 1.36, 95%CI [1.27,1.47]), and after 10pm (OR 1.36, 95%CI [1.27,1.47]) controlling for geographic region and the month the interview took place. CONCLUSIONS: Characteristics of solitary drinking largely align with characteristics we associated with drinking problems. Those who partake in at least one solitary drinking occasion are overall more likely to consume alcohol at risky levels, however, the number of drinks consumed in each occasion was lower during a solitary drinking occasion.
RESUMO
OBJECTIVE: Retailer licencing fees are a promising avenue to regulate tobacco availability. However, they face strong opposition from retailers and the tobacco industry, who argue significant financial impacts. This study compares the impacts of different forms of tobacco licence schemes on retailers' profits in Scotland. METHODS: We calculated gross profits from tobacco sales in 179 convenience stores across Scotland using 1 099 697 electronic point-of-sale records from 16 weeks between 2019 and 2022. We estimated different fees using universal, volumetric and separate urban/rural schemes. We identified the point at which 50% of retailers would no longer make a gross profit on tobacco sales for each scheme and modelled the financial impact of 10 incremental fee levels. The financial impact was assessed based on changes in retailers' tobacco gross profits. Differences by neighbourhood deprivation and urban/rural status were examined. RESULTS: The gross profit from tobacco per convenience store averaged £15 859/year. Profits were 2.29 times higher in urban (vs rural) areas and 1.59 times higher in high-deprivation (vs low-deprivation) areas, attributable to higher sales volumes. Tobacco gross profit decreased proportionally with increasing fee levels. Universal and urban/rural fees had greater gross profit reductions in rural and/or less deprived areas, where profits were lower, compared with volumetric fees. CONCLUSION: The introduction of tobacco licence fees offers a potential opportunity for reducing the availability of tobacco retailers. The likely impact of a tobacco licence fee is sensitive to the type of licence scheme implemented, the level at which fees are set and the retailers' location in relation to neighbourhood deprivation and rurality.
RESUMO
INTRODUCTION: Evidence shows that price is an important policy lever in reducing consumption of alcohol and tobacco. However, there is little evidence of the cross-price effect between alcohol and tobacco. METHODS: This paper uses an econometric model which estimates participation and consumption elasticities, on data from the UK Living Costs and Food Survey 2006-2017 and extends the literature by, for the first time, estimating joint price elasticities for disaggregated alcohol and tobacco products. This paper presents new price elasticities and compares them to the existing literature. RESULTS: The own-price elasticity estimates are all negative for both participation and consumption. There is no pattern to the estimates of cross-price elasticities. The elasticity estimates, when used in the Sheffield Tobacco and Alcohol Policy Model, produce bigger changes in consumption for the same change in price compared to other elasticity estimates in the existing literature. DISCUSSION AND CONCLUSIONS: Consumption of alcohol and tobacco are affected by the prices of one another. Policymakers should bear this in mind when devising alcohol or tobacco pricing policies.

BACKGROUND: Food diets are complex and a policy targeting one item of a person's diet does not affect their nutritional intake in a solely additive or subtractive manner. Policies tackling unhealthy diets are more likely to be adopted by governments if there is robust evidence to support them. To evaluate dietary policies, it is important to understand the correlations and interdependencies between food groups, as these can lead to unintended negative consequences. We aimed to see whether reductions in consumption of a particular group is related to a net improvement in nutritional intake, after taking into account patterns of consumption and substitution across food groups. METHODS: Detailed dietary data was collected using a 24-h online dietary assessment from the UK Biobank and Oxford Web Q (n = 185,611). We used panel data fixed effects methods to estimate changes in energy, saturated fat, total sugar, and fibre following a 100gram reduction across 44 food groups. We compare these estimates against the average nutritional value of that food group from the UK National Diet and Nutrition Survey. RESULTS: We find evidence of variation in whether a food is compensated between the main confectionery products. Crisps, savoury snacks, and sugar confectionery are less likely to be compensated, whereas chocolate confectionery, biscuits, and buns/cakes/pastries and pies are compensated. The result is particularly striking for chocolate confectionery which shows that while chocolate confectionery often has a high energy content, eating less chocolate confectionery is not associated with an equal reduction in energy. Instead, we find individuals switch or compensate for their reduction in chocolate confectionery consumption with other high energy food items. CONCLUSIONS: We find that sugar confectionery and crisps and savoury snacks are less likely to result in substitution than chocolate confectionery. This would suggest that food policies aiming to reduce the consumption of these food groups are more likely to result in overall lower consumption of unhealthy foods.

There is a growing but mixed literature on the health effects of minimum wages. If minimum wage changes have a statistically significant impact on health, this suggests health effects should be incorporated into cost-benefit analyses to capture wider policy impacts. Whilst most existing UK based literature examines the introduction of a minimum wage, this paper exploits the 2016, 2017 and 2018 UK National Minimum Wage (NMW) increases as natural experiments using a series of difference-in-differences models. Short Form-12 (SF-12) mental and physical component summary scores are used as dependent variables. In the base case and all sensitivity analyses, the estimated impact of NMW increases on mental and physical health are insignificant. The policy implication is that health effects should not be included in cost-benefit analyses examining the NMW.

BACKGROUND AND AIMS: Dual purchasers of alcohol and tobacco are at increased health risk from the interacting health impacts of alcohol and tobacco use. They are also at financial risk from exposure to the dual financial cost of policies that increase alcohol and tobacco prices. Understanding whose alcohol and tobacco use exposes them to these health and financial risks is important for understanding the inequality impacts of control policies. This study explores the extent to which household spending on alcohol and tobacco combined varies between socio-economic groups and compares this with results for households which purchase only one of the commodities. DESIGN: Cross-sectional analysis of household-level alcohol and tobacco purchasing data. SETTING: United Kingdom, 2012-17. PARTICIPANTS/CASES: A total of 26 021 households. MEASUREMENTS: We analysed transaction-level data from individual 14-day spending diaries in the Living Cost and Food Survey (LCFS). We used this to calculate expenditure, volumes of alcohol and tobacco purchased, and the price paid per unit of alcohol (1 unit = 8 g) and per stick of tobacco. This was compared with equivalized total expenditure and quintiles of equivalized household income. Prices were calibrated and pack sizes were imputed using empirical sales data from Nielsen/CGA to correct for reporting bias. FINDINGS: Dual purchasing households spent [95% confidence interval] more on alcohol and more on tobacco than their single-purchasing counterparts. In general, lower-income households spent less on both alcohol and tobacco than higher-income households. Furthermore, dual purchasing households in the lowest income group were most exposed to potential increases in price than were other income groups, with (CI = 12.41-13.15%) of their total household budget spent on alcohol and tobacco. CONCLUSIONS: Dual purchasers of alcohol and tobacco in the United Kingdom appear to be concentrated evenly among income groups. However, dual purchasers may experience particularly large effects from pricing policies, as they spend a substantially higher proportion of their overall household expenditure on alcohol and tobacco than do households that purchase only one of the commodities.

The effectiveness of alcohol duty increases relies on alcohol retailers passing the tax increase on to consumers. This study uses sales data from a market research company to investigate tax pass-through over 11 years for on-premise retailers in England and whether this varies across the price distribution, for different beverage categories and outlet types. Panel data quantile regression analysis is used to estimate the impact of 12 excise duty changes and 3 sales tax changes between 2007 and 2017 on prices. We use product-level quarterly panel data from for 777 alcoholic products. We undertake the regression at all outlets level separating products are analysed in seven broad beverage categories (Beer, Cider, RTDs, Spirits, Wine, Sparkling Wine, and Fortified Wine). We further test sensitivity by disaggregating outlets into seven outlet types. For all seven broad beverage categories, we find that there exists significant differences in tax pass-through across the price distribution. Retailers appear to "undershift" cheaper beverages (prices rise by less than the tax increase) and subsidise this loss in revenue with an "overshift" in the relatively more expensive products. Future modelling of tax change impacts on population subgroups could incorporate this evidence, and this is important because different socio-economic and drinker groups purchase alcohol at different points on the price distribution and hence are affected differently by tax changes. Governments could also potentially incorporate this evidence into future impact assessments.
