To assess the immediate impact of the introduction of minimum unit pricing (MUP) in Scotland on alcohol consumption and whether the impact differed by sex, level of alcohol consumption, age, social grade and level of residential deprivation of respondents.
Primary controlled interrupted time series analysis and secondary before-and-after analysis of the impact of introducing MUP in Scotland using alcohol consumption data for England as control.
Data from Kantar Worldpanel's Alcovision survey, a continuous retrospective online timeline follow-back diary survey of the previous week's alcohol consumption.
53 347 women and 53 143 men.
Introduction of a minimum price of 50 pence per UK unit (6.25 pence/g) for the sale of alcohol in Scotland on 1 May 2018.
Number of grams of alcohol consumed per week, in total, in off-trade (eg, at home) and in on-trade (eg, in pubs, restaurants).
Primary interrupted time series analyses found that the introduction of MUP was associated with a drop in reported weekly total alcohol consumption of 5.94 g (95% CI 1.29 to 10.60), a drop in off-trade consumption of 3.27 g (95% CI -0.01 to 6.56) and a drop in on-trade consumption of 2.67 g (95% CI -1.48 to 6.82). Associated reductions were larger for women than for men and were greater among heavier drinkers than for lighter drinkers, except for the 5% of heaviest drinking men for whom an associated increase in consumption was found. Secondary before-and-after analyses found that reductions in consumption were greater among older respondents and those living in less deprived areas. The introduction of MUP was not associated with a reduction in consumption among younger men and men living in more deprived areas.
Greater policy attention needs to be addressed to the heaviest drinking men, to younger men and to men who live in more deprived areas.
评估苏格兰最低单位定价（MUP）制度的引入对酒精消费的即时影响，以及这种影响是否因性别、饮酒量、年龄、社会阶层和受访者居住贫困程度的不同而有所差异。
主要采用控制中断时间序列分析和次要的苏格兰 MUP 引入前后分析，使用英格兰的酒精消费数据作为对照。
来自 Kantar Worldpanel 的 Alcovision 调查的数据，这是一项针对前一周酒精消费的连续回顾性在线时间线追踪调查。
53347 名女性和 53143 名男性。
2018 年 5 月 1 日起，苏格兰每单位（6.25 便士/克）销售酒精的最低价格为 50 便士。
每周总饮酒量（包括非贸易和贸易渠道），以克为单位。
主要的中断时间序列分析发现，MUP 的引入与报告的每周总酒精消费量下降 5.94 克（95%CI 1.29 至 10.60）有关，非贸易渠道的消费量下降 3.27 克（95%CI -0.01 至 6.56），贸易渠道的消费量下降 2.67 克（95%CI -1.48 至 6.82）。女性的降幅大于男性，重度饮酒者的降幅大于轻度饮酒者，但在 5%的最重度饮酒男性中发现了消费增加的关联。次要的引入前后分析发现，消费的减少在年龄较大的受访者和生活在贫困程度较低地区的受访者中更为明显。MUP 的引入与年轻男性和生活在贫困程度较高地区的男性消费减少无关。
需要更加关注重度饮酒男性、年轻男性和生活在贫困程度较高地区的男性。
