Caffeine Usage among Medical Students and Their Knowledge of Its Benefits and Side Effects

Abstract

Caffeine, known for its stimulating effects, is widely consumed by medical students to counteract stress, fatigue, and enhance alertness for academic performance. This study aimed to assess the prevalence, types, and motivations for caffeine consumption among medical students, as well as their knowledge of its benefits and potential side effects.

A cross-sectional online survey was conducted among first- to sixth-year medical students at Al-Iraqia University and Al-Mustansiriyah University. Data were collected via Google Forms, distributed through academic online platforms from Jan 23 to 30th, 2024, to investigate caffeine consumption patterns and general knowledge.

A total of 507 students participated, with 471 (93%) reporting caffeine consumption. The Majority were female (67.1%). The most commonly consumed caffeine product was Coffee (60.4%), followed by tea (56.2%). Daily caffeine consumption was reported by 61.3% of students, with most consuming 1-3 cups per day, while a minority (7%) consumed more than three cups. The primary reason for caffeine intake was to stay awake (60.6%). Additionally, 66.3% of students reported an increase in caffeine consumption upon entering medical school. While students exhibited limited general knowledge about caffeine, they demonstrated better awareness regarding side effects and withdrawal symptoms.

A significant proportion of medical students consume caffeine, predominantly in the form of Coffee, with increased intake observed during examination periods. Although consumption levels were generally within safe limits, the findings highlight the need for greater awareness regarding the long-term effects of excessive caffeine consumption.
