This commentary discusses the paper by Rossheim and Thombs (Alcohol Clin Exp Res 35, 2011), which examined the relationship between type of alcohol mixer (regular caffeinated cola, diet caffeinated cola, energy drink, or no mixer) and breath alcohol readings in bar patrons.
The significance of the findings of this study and new unaddressed questions for the field are discussed.
Rossheim and Thombs (2011) reported that breath alcohol concentration readings were highest when patrons reported the consumption of caffeine mixers that were artificially sweetened (i.e., diet cola), after adjusting for potential confounds. Women were more likely to consume diet cola-caffeinated mixed drinks.
The findings from this field study raise several new interesting questions. Given the reported gender difference in consumption of diet cola-caffeinated mixed drinks, more research is needed regarding gender differences in gastric emptying time for alcoholic beverages mixed with artificially sweetened versus sucrose sweetened caffeinated drinks. In addition, the recent explosion in the energy drink market has resulted in the availability of sugar-free or diet versions of most energy drink products. The implications of mixing diet energy drinks with alcohol are unknown.
本文评论了 Rossheim 和 Thombs 发表于《酒精临床与实验研究》（Alcohol Clin Exp Res 35, 2011）的论文，该论文探讨了酒吧顾客饮用的酒精混合饮料类型（普通含咖啡因可乐、低卡含咖啡因可乐、能量饮料或不含混合饮料）与呼气酒精读数之间的关系。
讨论了该研究结果的意义以及该领域新出现的未解决的问题。
Rossheim 和 Thombs（2011）报告称，在调整了潜在混杂因素后，报告饮用人工甜味剂（即低卡可乐）咖啡因混合饮料的顾客的呼气酒精浓度读数最高。女性更有可能饮用含低卡可乐和咖啡因的混合饮料。
这项现场研究的结果提出了几个新的有趣问题。鉴于报告的女性饮用含低卡可乐和咖啡因混合饮料的性别差异，需要更多关于混合人工甜味剂与蔗糖甜味剂的含咖啡因饮料时，酒精在胃肠道排空时间方面的性别差异的研究。此外，能量饮料市场的爆炸式增长导致大多数能量饮料产品都有低糖或低卡版本。混合低糖能量饮料和酒精的影响尚不清楚。
