Background: Caffeine consumption by young people has increased dramatically over the last decade through increased coffee consumption and "energy drinks." In higher amounts, caffeine causes many adverse effects that are cause for concern. Purpose: Purposes of this study were to determine: (1) the amount of caffeine consumed by a sample of college students, (2) beliefs regarding caffeine consumption, (3) reported perceived benefits and adverse effects of caffeine consumption, (4) reasons for consuming caffeine, and (5) predictors of caffeine consumption. Methods: An anonymous survey was administered 300 freshmen attending a southeastern university. Results: Eighty-three percent of the students reported having at least one sign/symptom of caffeine intoxication in the past; 51% reported having at least one sign/symptom of caffeine withdrawal. Students consumed three to five times the recommended amount of caffeine. Father's social index, participation in organized activity in college and three alertness items (concentration, keep awake, wake up) were significant predictors of caffeine consumption. Discussion: Students ingested caffeine at levels that could cause negative health effects and seemed unaware of the total amount of caffeine consumed. Translation to Health Education Practice: More information about caffeine should be incorporated into health education at all levels, so students can identify and avoid negative effects along with caffeine withdrawal and addiction.
