Caffeinated beverages are a part of daily life. Caffeinated beverages such as coffee, tea, energy drinks, and soft drinks are easy to purchase and are frequently consumed by young college students. Moreover, smoking influences the consumption of caffeinated beverages. The concentration of caffeine in these products is an attractive factor for individuals that desire the effects of caffeine; however, abusing such products may lead to poor sleep quality. The motivations that drive caffeinated beverage consumption were investigated in this study through a survey. Self-reported questionnaires were distributed on campus to students enrolled at a university in Korea. The motivations of the students for consuming each caffeinated beverage and their sleep quality were investigated. The results of exploratory factor analysis showed the motivations for caffeinated beverage consumption were alertness, taste, mood, socialization, health benefits, and habit. The motivations for consuming each caffeinated beverage product were different. For instance, coffee consumption was motivated by a desire for alertness (B = .107, SE = .049, t = 2.181, < 0.05) and by habit (B = .345, SE = .046, t = 7.428, < 0.001), whereas tea consumption was influenced by socialization (B = .142, SE = .060, t = 2.357, < 0.05). Energy drink consumption was motivated by a desire for alertness (B = .100, SE = .034, t = 2.966, < 0.01) and health benefits (B = .120, SE = .051, t = 2.345, < 0.05), while the consumption of soft drinks was not motivated by any specific factors. Caffeinated beverage consumption did not show a significant relationship with sleep quality, although the general sleep quality of the respondents was poor. Smoking status showed significant differences in coffee and tea consumption as well as sleep quality. Smokers had a higher intake of coffee and a lower intake of tea than non-smokers. No interaction effect between smoking and coffee on sleep quality was found. Labeling detailing the amount of caffeine in products is necessary and a cautionary statement informing consumers that smoking cigarettes enhances the effects of caffeine should be included.
含咖啡因的饮料是日常生活的一部分。咖啡、茶、能量饮料和软饮料等含咖啡因的饮料购买方便，经常被年轻的大学生饮用。此外，吸烟会影响含咖啡因饮料的消费。本研究通过调查研究了饮用含咖啡因饮料的动机。在韩国的一所大学的校园里分发了自我报告的问卷，调查了学生饮用每种含咖啡因饮料的动机和睡眠质量。探索性因素分析的结果表明，饮用含咖啡因饮料的动机是提神、口味、情绪、社交、健康益处和习惯。饮用每种含咖啡因饮料的动机不同。例如，喝咖啡的动机是提神（B=.107，SE=.049，t=2.181， < 0.05）和习惯（B=.345，SE=.046，t=7.428， < 0.001），而喝茶则受到社交的影响（B=.142，SE=.060，t=2.357， < 0.05）。能量饮料的消费动机是提神（B=.100，SE=.034，t=2.966， < 0.01）和健康益处（B=.120，SE=.051，t=2.345， < 0.05），而软饮料的消费则没有受到任何特定因素的影响。尽管受访者的总体睡眠质量较差，但含咖啡因饮料的消费与睡眠质量没有显著关系。吸烟状况在咖啡和茶的消费以及睡眠质量方面显示出显著差异。吸烟者比不吸烟者摄入更多的咖啡和更少的茶。没有发现吸烟和咖啡对睡眠质量的交互作用。有必要在产品标签上详细说明咖啡因的含量，并告知消费者吸烟会增强咖啡因的作用。
