Abstract
BackgroundThe effect of caffeine on the human body, both short-term and long-term, has been studied in great depth, particularly its association with psychiatric disorders. This study aims to investigate whether there is a correlation between caffeine intake and anxiety and depression among college students.MethodologyA survey was administered to college students at Florida State University. Data regarding participant characteristics and caffeine intake were collected. Generalized Anxiety Disorder-7 and Patient Health Questionnaire-9 scores were used to assess symptoms of anxiety and depression, respectively.ResultsA total of 114 participants were included in the survey, consisting mainly of women (94 [82.5%]) and junior-level students (37 [32.5%]). The main source of caffeine was coffee (64.0%), and the main reasons for caffeine intake were pleasure (43.9%) and to study outside of class (29.8%); however, no association was found between sex or grade point average and number of cups of caffeine consumed. Upper levels of education (super senior or fifth-year students), depressive symptoms (poor appetite, overeating, sleep disorders, depressed mood), and anxiety were statistically associated with greater caffeine intake (P < 0.05).ConclusionsAs caffeine is commonly consumed and our study showed that its intake was associated with depressive symptoms and higher levels of anxiety in college students, further studies are needed to determine a possible causality, so that measures may be taken to educate these students about alternative methods for increasing energy and alertness.

Summary
Caffeine is widely used as a source of energy. Pills, soda, and energy drinks are some of the most popular sources of caffeine. Some of the benefits that have been attributed to moderate caffeine intake include increased attention, alertness, mood elevation, increased cognitive function and fewer cognitive failures, lower risk of suicide, and fewer depressive symptoms [1]. Caffeine use is extremely prevalent among college students. The college lifestyle, appears to lend itself to higher caffeine intake compared to the rest of the population [2]. College students use very high doses of caffeine, an average of over 800 mg/day, which is approximately double the recommended safe dosage [3]. This study aims to investigate whether there is a correlation between caffeine intake and anxiety and depression among college students
