The main aim of these studies was to explore the influence of volume information on glassware on the time taken to consume an alcoholic beverage.
In Study 1, male and female social alcohol consumers ( n = 159) were randomised to drink 12 fl oz of either low or standard strength lager, from either a curved glass marked with yellow tape at the midpoint or an unmarked curved glass, in a between-subjects design. In Study 2, male and female social alcohol consumers ( n = 160) were randomised to drink 12 fl oz of standard strength lager from either a curved glass marked with ¼, ½ and ¾ volume points or an unmarked curved glass, in a between-subjects design. The primary outcome measure for both studies was total drinking time of an alcoholic beverage.
In Study 1, after removing outliers, total drinking time was slower from the glass with midpoint volume marking [mean drinking times (min): 9.98 (marked) vs. 9.55 (unmarked), mean difference = 0.42, 95% CI: -0.90, 1.44]. In Study 2, after removing outliers, total drinking time was slower from the glass with multiple volume marks [mean drinking times: 10.34 (marked) vs. 9.11 (unmarked), mean difference = 1.24, 95% CI: -0.11, 2.59]. However, in both studies confidence intervals were wide and also consistent with faster consumption from marked glasses.
Consumption of an alcoholic beverage may be slower when served in glasses with volume information. Replication in larger studies is warranted.
这些研究的主要目的是探究玻璃器皿上的容量信息对饮用酒精饮料所用时间的影响。
在研究1中，将社交场合饮酒的男性和女性消费者（n = 159）采用组间设计随机分为两组，分别从带有黄色胶带标记中点的弧形玻璃杯或无标记的弧形玻璃杯中饮用12液量盎司的低强度或标准强度淡啤酒。在研究2中，将社交场合饮酒的男性和女性消费者（n = 160）采用组间设计随机分为两组，分别从带有1/4、1/2和3/4容量标记的弧形玻璃杯或无标记的弧形玻璃杯中饮用12液量盎司的标准强度淡啤酒。两项研究的主要结局指标均为酒精饮料的总饮用时间。
在研究1中，去除异常值后，带有中点容量标记的玻璃杯的总饮用时间较慢[平均饮用时间（分钟）：9.98（有标记）对9.55（无标记），平均差异 = 0.42，95%CI：-0.90，1.44]。在研究2中，去除异常值后，带有多个容量标记的玻璃杯的总饮用时间较慢[平均饮用时间：10.34（有标记）对9.11（无标记），平均差异 = 1.24，95%CI：-0.11，2.59]。然而，在两项研究中，置信区间都很宽，也与有标记玻璃杯饮用速度更快一致。
用带有容量信息的玻璃杯盛放酒精饮料时，饮用速度可能会较慢。有必要在更大规模的研究中进行重复验证。
