在过去的20年里，不列颠哥伦比亚省的最低酒精价格断断续续地进行了调整。本研究估计这些调整对酒精消费的影响。设计以价格和其他经济数据为自变量的总酒精消费量的时间序列和纵向模型。背景：加拿大不列颠哥伦比亚省。加拿大不列颠哥伦比亚省15岁以上的人口。不列颠哥伦比亚酒类分销分支提供了1989-2010年酒精价格和不同饮料销售的数据。家庭收入数据来自加拿大统计局。结果纵向估计表明，酒精饮料的最低价格增加10%，减少其消费相对于其他饮料的16.1%（P < 0.001）。时间序列估计表明，最低价格提高10%，烈酒和利口酒的消费量就会减少6.8（P = 0.004），葡萄酒8.9%（P = 0.033），含酒精苏打水和苹果酒13.9%（P = 0.067），啤酒1.5%（P = 0.043）和所有酒精饮料3.4%（P = 0.007）。结论：提高酒精饮料的最低价格可以大大减少酒精消费。
Aims Minimum alcohol prices in British Columbia have been adjusted intermittently over the past 20 years. The present study estimates impacts of these adjustments on alcohol consumption. Design Time-series and longitudinal models of aggregate alcohol consumption with price and other economic data as independent variables. Setting British Columbia (BC), Canada. Participants The population of British Columbia, Canada, aged 15 years and over. Measurements Data on alcohol prices and sales for different beverages were provided by the BC Liquor Distribution Branch for 1989-2010. Data on household income were sourced from Statistics Canada. Findings Longitudinal estimates suggest that a 10% increase in the minimum price of an alcoholic beverage reduced its consumption relative to other beverages by 16.1% (P < 0.001). Time- series estimates indicate that a 10% increase in minimum prices reduced consumption of spirits and liqueurs by 6.8% (P = 0.004), wine by 8.9% (P = 0.033), alcoholic sodas and ciders by 13.9% (P = 0.067), beer by 1.5% (P = 0.043) and all alcoholic drinks by 3.4% (P = 0.007). Conclusions Increases in minimum prices of alcoholic beverages can substantially reduce alcohol consumption.
