Energy Drink and Other Substance Use Among Adolescent and Young Adult Emergency Department Patients

Objective: This study aimed to understand current patterns of energy drink use and compare the extent of usage of energy drinks and other commonly used and misused substances between adolescent (13-17-years-old) and young adult (18-25-years-old) emergency department (ED) patients. Methods: During a 6-week period between June and August 2010, all patients presenting to an adult or pediatric ED were asked to complete a computer-based, anonymous questionnaire regarding use of energy drinks and other substances. Wilcoxon rank-sum, 2-sample tests of binomial proportions, Pearson chi(2) testing, and regression models were used to compare energy drink and substance use by age groups. Results: Past 30-day energy drink use was greater for young adults (57.9%) than adolescents (34.9%) (P < 0.03). Adolescents typically consumed a mean of 1.5 and young adults a mean of 2.6 energy drinks per day when using energy drinks and drank at most a mean of 2.4 and 2.6 drinks per day, respectively. Among adolescents, energy drink usage was more common than alcohol, "street" or illicit drugs, and tobacco usage, but less common than caffeine product usage. For young adults, energy drink usage was more common than "street" or illicit drugs, but less common than caffeine use, and similar to tobacco and alcohol usage. Young adult energy drink users were more likely than young adult non-energy drink users also to use tobacco and caffeine. Conclusions: Energy drink use is common among ED patients. Given the high prevalence of energy drink use observed, emergency physicians should consider the involvement of energy drinks in the presentations of young people.
