Is the Consumption of Energy Drinks Associated With Academic Achievement Among College Students?
Despite widely reported side effects, use of energy drinks has increased among college students, who report that they consume energy drinks to help them complete schoolwork. However, little is known about the association between energy drink use and academic performance. We explored the relationship between energy drink consumption and current academic grade point average (GPA) among first year undergraduate students. Participants included 844 first year undergraduates (58.1 female; 50.7 White) Students reported their health behaviors via an online survey. We measured energy drink consumption with two measures: past month consumption by number of drinks usually consumed in 1 month and number consumed during the last occasion of consumption. We used multiple linear regression modeling with energy drink consumption and current GPA, controlling for gender, race, weekend and weekday sleep duration, perceived stress, perceived stress management, media use, and past month alcohol use. We found that past month energy drink consumption quantity by frequency (p 0.001) and energy drinks consumed during the last occasion (p 0.001) were associated with a lower GPA. Energy drinks consumed during the last occasion of consumption (p 0.01) remained significantly associated with a lower GPA when controlling for alcohol use. While students report using energy drinks for school related reasons, our findings suggest that greater energy drink consumption is associated with a lower GPA, even after controlling for potential confounding variables. Longitudinal research is needed that addresses whether GPA declines after continued use of energy drinks or if students struggling academically turn to energy drinks to manage their schoolwork.
