The Relationship Between Energy Drink Consumption, Caffeine Content, and Nutritional Knowledge Among College Students.

Abstract

We sought to determine which demographic characteristics influence energy drink consumption habits and to examine whether caffeine content and knowledge of human nutrition affect college students' decisions to consume these beverages. We used an online survey to ask 265 college students, who did not participate in a varsity sport, to complete a survey consisting of demographic questions, the General Knowledge Questionnaire for adults, and questions about energy drink consumption habits. We found, overall, that 23.1% of our sample used energy drinks. When compared to non-consumers (76.9%), users had a significantly lower GPA, were older, and preferred drinks with a higher caffeine content. Users reported that they consumed these drinks because they wanted to feel more alert and they enjoyed the taste, even though they reported adverse effects such as trouble sleeping, shaking and tremors, and stomachaches. Knowledge of human nutrition did not affect users' choice to consume these drinks. Although the majority of college students do not consume energy drinks, room for improvement remains to curb the use of these caffeinated beverages amongst college students.
