For consumers to follow drinking guidelines and limit their risk of negative consequences they need to track their ethanol consumption. This paper reviews published research on the ability of consumers to utilise information about the alcohol content of beverages when expressed in different forms, for example in standard drinks or units versus percentage alcohol content.
A review of the literature on standard drink definitions and consumer understanding of these, actual drink pouring, use of standard drinks in guidelines and consumer understanding and use of these.
Standard drink definitions vary across countries and typically contain less alcohol than actual drinks. Drinkers have difficulty defining and pouring standard drinks with over-pouring being the norm such that intake volume is typically underestimated. Drinkers have difficulty using percentage alcohol by volume and pour size information in calculating intake but can effectively utilise standard drink labelling to track intake. Standard drink labelling is an effective but little used strategy for enabling drinkers to track their alcohol intake and potentially conform to safe or low-risk drinking guidelines.
为了让消费者遵循饮酒指南并限制其负面后果的风险，他们需要跟踪自己的乙醇摄入量。本文综述了关于消费者在不同形式下（例如标准饮品或单位与酒精含量百分比）使用关于饮料中酒精含量的信息的能力的已发表研究。
对标准饮品定义以及消费者对这些定义的理解、实际饮品的倒出、指南中标准饮品的使用以及消费者对这些的理解和使用方面的文献进行了综述。
标准饮品的定义在各国之间存在差异，并且通常比实际饮品含有的酒精少。饮酒者在定义和倒出标准饮品方面存在困难，过度倒出是常态，因此摄入量通常被低估。饮酒者在使用体积百分比酒精和倒出量信息来计算摄入量方面存在困难，但可以有效地利用标准饮品标签来跟踪摄入量。标准饮品标签是一种有效的但使用较少的策略，可使饮酒者能够跟踪他们的饮酒量并有可能遵守安全或低风险的饮酒指南。
