Caffeine Consumption & Perception of Its Effects Amongst University Students

Abstract

Introduction: A variety of research studies have shown that caffeine usage is highly prevalent among university students and many of them have different perception of its effect on their mental and physical health. These perceptions can influence the intake of caffeine which may lead to its addiction, resulting in serious public health consequences.

Aims & Objectives: The objective of the study is to determine the frequency of caffeine consumption and the perception of its effects among university students.

Place and duration of study: This study was conducted within 6 months duration, from May 2018 to October 2019 among students of three private universities in Lahore, Pakistan.

Material & Methods: This was a descriptive cross-sectional study. A sample size of 670 university students was taken and the data were collected from three private universities of Lahore through convenience sampling technique. The perception of effects of caffeine was determined through a pre-validated questionnaire, Caffeine Expectancy Questionnaire (CaffEQ) from consumers and nonconsumers of caffeine.

Results: A total of 670 university students participated in the study, out of which, 278 (41.5%) were males and 392 (58.5%) were females. 506 (75.5%) participants were consumer of caffeine, while 164 (24.5%) were non consumer. The occurrence of caffeine consumption was more in males (79.9%) than in females (72.4%). Participants reported that they consume caffeine because it makes them feel more alert (83.4%), they experience caffeine withdrawal without caffeine (83%) and caffeine makes them feel more energetic (80.6%). The perceptions due to which participants don't consume caffeine were that they expect caffeine makes their heartbeat irregular (81.7%), they don't like the way caffeine makes them feel (80.5%) and caffeine makes them irritable (76.8%).

Conclusion: The study concludes that male students had more tendencies towards caffeine consumption than females. Perceptions for consuming caffeine were feeling of alertness, experiencing caffeine withdrawal symptoms, feeling of energy and ability to work over long periods of time after having caffeine. The perceptions for not consuming caffeine were irregular heartbeat, bad feelings, irritability, and sleep disturbances.
