Caffeine is a stimulant that can be found in many sources of beverages such as coffee, tea, chocolate, matcha, soft drinks, and energy drinks. It has been consumed by people to gain benefits such as improving their alertness and staying awake. University students have been found to consume caffeine to get those benefits, especially during stressful situations. Therefore, this cross-sectional study is conducted to measure the frequency of caffeinated beverage consumption among undergraduate students in the USM health campus as well as to determine the sociodemographic factors, BMI, and sleep quality association with frequency of caffeine intake. A convenience sampling study was conducted with 162 (n = 43 males, n = 119 females) undergraduate students from year 1 until year 3 with the age range between 19 to 25 years old from the School of Health Sciences, School of Medical Sciences, and School of Dental Sciences. The survey questionnaire consisted of sociodemographic factors, Caffeine Consumption Patterns, and Pittsburgh Sleep Quality Index (PSQI) to collect data from the respondents and were assessed using SPSS (Version 29.0) to provide descriptive analysis and Fisher’s Exact Test. This study found no significant association between caffeinated beverages consumption with sociodemographic factors such as gender (p = 0.351), age (p = 0.353), school (p = 0.545), year of study (p = 0.646), BMI (p = 0.198), and sleep quality (p = 0.692) among undergraduate students. Nonetheless, a significant association has been found between scholarship status and frequency of caffeine intake (p = 0.002). This study indicates that scholarship students consumed higher frequency of caffeine compared to self-sponsored university students. However, further investigations are needed to…
