High levels of alcohol consumption and increases in heavy episodic drinking (binge drinking) are a growing public concern, due to their association with increased risk of personal and societal harm. Alcohol consumption has been shown to be sensitive to factors such as price and availability. The aim of this study was to explore the influence of glass shape on the rate of consumption of alcoholic and non-alcoholic beverages.
This was an experimental design with beverage (lager, soft drink), glass (straight, curved) and quantity (6 fl oz, 12 fl oz) as between-subjects factors. Social male and female alcohol consumers (n = 159) attended two experimental sessions, and were randomised to drink either lager or a soft drink from either a curved or straight-sided glass, and complete a computerised task identifying perceived midpoint of the two glasses (order counterbalanced). Ethical approval was granted by the Faculty of Science Research Ethics Committee at the University of Bristol. The primary outcome measures were total drinking time of an alcoholic or non-alcoholic beverage, and perceptual judgement of the half-way point of a straight and curved glass.
Participants were 60% slower to consume an alcoholic beverage from a straight glass compared to a curved glass. This effect was only observed for a full glass and not a half-full glass, and was not observed for a non-alcoholic beverage. Participants also misjudged the half-way point of a curved glass to a greater degree than that of a straight glass, and there was a trend towards a positive association between the degree of error and total drinking time.
Glass shape appears to influence the rate of drinking of alcoholic beverages. This may represent a modifiable target for public health interventions.
由于饮酒量高和重度饮酒（狂饮）的增加与个人和社会伤害风险增加有关，因此这是公众日益关注的问题。饮酒量对价格和供应等因素敏感。本研究旨在探讨玻璃形状对酒精和非酒精饮料消耗率的影响。
这是一项具有饮料（拉格啤酒，软饮料），玻璃杯（直壁，弯壁）和数量（6 液盎司，12 液盎司）为组间因素的实验设计。社交男性和女性酒精消费者（n = 159）参加了两个实验会议，并随机从弯壁或直壁玻璃杯饮用拉格啤酒或软饮料，并完成一项计算机化任务，以识别两个玻璃杯的中点（顺序平衡）。布里斯托大学科学研究伦理委员会批准了伦理。主要观察指标是饮用酒精或非酒精饮料的总时间，以及对直壁和弯壁玻璃杯中点的感知判断。
与弯壁玻璃杯相比，参与者从直壁玻璃杯饮用酒精饮料的速度慢 60％。这种效果仅在全玻璃杯中观察到，而在半满玻璃杯中则没有观察到，在非酒精饮料中也没有观察到。参与者还错误地判断了弯壁玻璃杯的中点程度大于直壁玻璃杯，并且错误程度与总饮酒时间之间存在正相关趋势。
玻璃形状似乎会影响酒精饮料的饮用速度。这可能是公共卫生干预措施的可改变目标。
