Malinauskas et al. (2007) examined caffeinated energy drink (ED) consumption patterns among college students. The researchers looked at the prevalence and frequency of ED consumption in six conditions, which were insufficient sleep, to increase general energy, usage while studying, driving for long periods of time, drinking with alcohol and drinking to treat a hangover. They also looked at the prevalence of adverse side effects and the effects of the dosage of EDs consumed. Malinauskas and colleagues utilized a questionnaire completed by 496 participants, aged 21.5 ? 3.7 years, who attended a large state university located in the Central Atlantic region of the United States. The researchers consulted with the university’s Institutional Review Board for Research with Human Subjects, and students that were informed of the study protocol and were willing to participate were administered the 2 minute questionnaire. Of the 496 individuals who completed the questionnaire, 51% of participants (n = 253) reported drinking greater than one energy drink each month in an average month for the current semester, 53% of them being female and 42% being male. In regards to the six situations of energy drink use among college ED users in an average month or the current semester, it was found that the most common reason to drink EDs was for insufficient sleep, as 67% of ED users indicated. Most ED users (65%) consumed EDs to increase their energy in general. It was also found that 50% of ED users drank the caffeinated beverages while studying or completing a major course project.
