Effects of beverage preference, beverage type and subject gender on ad libitum consumption of alcoholic beverages in the laboratory were evaluated. Undergraduate social drinkers (18 male, 18 female), with equal numbers of each gender stating a preference for beer, wine or mixed drinks, were selected. Subjects participated in three separate 30-minute ad lib drinking sessions and were presented with one of the three types of alcoholic beverage at each session. Data on total volume of beverage and of absolute ethanol consumed as well as blood alcohol concentration (BAC) attained were collected in each session. Subjects preferring wine or mixed drinks drank more alcohol and reached higher BACs when imbibing their beverage of choice than when drinking non-preferred beverages. Subjects preferring beer, however, showed no differences on these drinking measures as a function of beverage type. Men's reports of routine alcohol use had a high positive correlation with actual alcohol consumption observed in the laboratory, whereas for female subjects the correlation was near zero. Implications for interpretation of past ad lib drinking studies and the planning of future ones are discussed.
评估了饮料偏好、饮料类型和受试者性别对实验室中酒精饮料随意摄入量的影响。选取了本科社交饮酒者（18名男性，18名女性），每种性别中表示偏好啤酒、葡萄酒或混合饮料的人数相等。受试者参加了三次单独的30分钟随意饮酒环节，每次环节提供三种酒精饮料中的一种。每次环节都收集了饮料总量、绝对乙醇摄入量以及达到的血液酒精浓度（BAC）的数据。偏好葡萄酒或混合饮料的受试者在饮用他们选择的饮料时比饮用非偏好饮料时摄入更多酒精，且血液酒精浓度更高。然而，偏好啤酒的受试者在这些饮酒指标上未表现出因饮料类型而产生的差异。男性关于日常饮酒的报告与实验室观察到的实际酒精摄入量高度正相关，而女性受试者的相关性接近零。讨论了对过去随意饮酒研究解读和未来研究规划的启示。
