Providing calorie information for alcoholic beverages is a potential public-health intervention which may serve to reduce alcohol use but also prevalence of overweight/obesity. Equivocal evidence has been found for the effectiveness of alcohol calorie information at reducing drinking intentions as well as purchasing and consumption. However, the extent at which calorie information 'on-trade' will impact consumer behaviour for both alcohol and food consumption has not been investigated.
(1) To examine the presence of alcohol calorie labelling for hypothetical purchasing of alcohol and food in typical UK restaurant scenarios. (2) To determine the characteristics of individuals who will be likely to choose to view alcohol calorie labels.
Two online randomised control trials using a hypothetical menu selection. In experiment one (N = 325) participants were randomised to the presence or absence of alcohol calorie labels. In experiment two (N = 1081) individuals were randomised to alcohol calorie labels absent or the choice to view alcohol calorie labels. The primary outcome for each study was calories ordered from alcoholic beverages.
There was no evidence that the presence of alcohol calorie information on restaurant menus impacted the number of calories ordered from alcoholic beverages or from food and soft drinks. Younger individuals and individuals who exhibit greater motives for good health were more likely to choose to view alcohol calorie labels.
In two online, hypothetical experiments there is no evidence for alcohol calorie labelling impacting consumer decisions to order alcohol or food. Given the choice, a self-selecting group of individuals who are more motivated by health concerns will view alcohol calorie labels, and in turn may be less likely to order alcohol.
提供酒精饮料的热量信息是一种潜在的公共卫生干预措施，可能有助于减少酒精使用量，同时也能降低超重/肥胖的患病率。有证据表明，酒精热量信息在减少饮酒意图以及购买和消费方面是有效的。然而，还没有研究过“贸易中”的热量信息会在多大程度上影响消费者对酒精和食物消费的行为。
（1）研究在典型的英国餐馆场景中，假设购买酒精和食物时是否存在酒精卡路里标签。（2）确定哪些人更有可能选择查看酒精卡路里标签。
使用假设菜单选择进行了两项在线随机对照试验。在实验一（N=325）中，参与者被随机分配到有或没有酒精卡路里标签的情况下。在实验二（N=1081）中，个体被随机分配到没有酒精卡路里标签或选择查看酒精卡路里标签的情况下。每个研究的主要结果是从酒精饮料中订购的卡路里。
没有证据表明餐馆菜单上是否有酒精卡路里信息会影响从酒精饮料或食物和软饮料中订购的卡路里数量。年轻人和更关注健康的个体更有可能选择查看酒精卡路里标签。
在两项在线假设性实验中，没有证据表明酒精卡路里标签会影响消费者点酒或点菜的决定。在有选择的情况下，一组更关注健康问题的个体将查看酒精卡路里标签，从而可能不太可能点酒。
