Caffeine consumption among medical students: an exploratory study in a medical school in a sub–Himalayan state of India

Background Among the psychostimulants, caffeine is the most commonly used compound with beneficial effects in low to moderate intake. Medical students due to extended scholastic work do indulge in caffeine intake. The present study aimed to explore the prevalence, determinants and its positive and negative effects among medical students in a tertiary care teaching hospital in Jammu, India.

Methods The present cross sectional study was conducted in the month of December, 2023. Online questionnaire was shared with all the undergraduate MBBS students of the medical school and were directed to submit their responses. Data thus collected was entered into Excel spread sheet and analysed.

Results Prevalence of caffeine intake among the respondents was 85.7%. The most common caffeinated beverage consumed was tea followed by coffee while energy drinks were least consumed. Among the reasons for consumption, feeling refreshed and combating drowsiness were cited as two main reasons. Respondents reported gastritis (41%), insomnia (30%), anxiety (18%) and palpitation (18%) as major side effects post consumption.

Conclusions The frequency of caffeine use among the respondents was more on the regular days in contrast to stress related exam days as reported in other studies. Intake of caffeinated beverages favourable time was morning. More studies are recommended to study long term results of consumption of caffeinated beverages.
