Abstract

Caffeine is one of the famous organic compounds in most beverages, especially coffee, tea, and soft drinks. Considering the benefits of caffeine, consumption of caffeine among undergraduate students has been normalcy as caffeine improves alertness and daily performance. However, consuming too much caffeine (more than 400 mg) daily could promote adverse effects such as poor sleeping habits and insomnia. Objective: This quantitative survey study aimed to study the association of caffeine intake with sleeping habits and insomnia among undergraduate students in the Faculty of Medicine and Health Sciences, UPM. Methodology: A set of modified questionnaires from the Caffeine Consumption Questionnaire (CCQ), the Pittsburgh Sleeping Quality Index (PSQI), and the Insomnia Severity Index (ISI) were used in this study. The questionnaire consists of four parts; Part 1: Demographic section, Part 2: Caffeine Consumption, Part 3: Sleeping Habits Determination, and Part 4: Insomnia Severity Index. All 18 years old and above, active undergraduate students in the faculty were eligible while undergraduate students from other universities, foundation students, postgraduate students, and UPM staff were excluded from this study. Results: A total of 348 respondents were collected, whereby 337 (96.8%) of them provided a valid response. The majority of the respondents were female (73.3%), aged 23 years old (28.8%) with a mean age of 21.89 ± 1.270 years and Malay (73.9%). Most of the respondents consume caffeine in their daily life (n = 333, 98.8%; Median ± IQR = 333.50 ± 442.90 mg). Out of those who consumed caffeine, 138 (41.4%) fell into a high intake classification, 79 (23.7%) were classified as a moderate intake and the rest (34.8%) were classified as a low intake. The taste of the caffeine was the main reason influencing caffeine consumption among caffeine consumers (47.7%), followed by to help respondents feel more alert (44.1%) and keeping the respondents awake in the morning (43.2%). Most of the respondents exhibit a good sleeping habit (n = 319, 94.7%). Therefore, there was no significant association between caffeine consumption with sleeping habits, X2 = 1.822, p = 0.402. Among respondents, 141 (41.8%) experienced subthreshold insomnia, 54 (16%) with moderate clinical insomnia and 7 (2.1%) experienced severe clinical insomnia. A high caffeine consumption was likely to increase the severity of the insomnia. Even so, there is no significant association between caffeine consumption with the severity of insomnia, X2 = 8.069, p = 0.217. Conclusion: These findings expressed that there is no impact of caffeine consumption on poor sleeping habit that leads to an increase in the severity of the insomnia. The taste of the caffeine was the key that influenced caffeine consumption.
