Abstract
Objective
This study aims to examine the relationship between caffeine consumption and sleep quality among healthcare professionals.
Method
This cross-sectional study was conducted on 98 healthcare professionals working at Balıkesir Havran State Hospital. Participants' caffeine consumption levels were assessed using the Caffeine Consumption Frequency Questionnaire, and their sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). The data were analyzed using the SPSS 22.0 statistical software package. Descriptive statistics, student’s t-test, and linear regression analyses were performed, with a significance level set at p < 0.05.
Results
The average daily caffeine consumption among participants was found to be 279.12 ± 168.50 mg. Although the mean caffeine intake was slightly higher among females, this difference was not statistically significant. 57.1 % of the participants were evaluated as having poor sleep quality. According to the regression analysis, daily caffeine consumption was positively associated with sleep duration (p < 0.05), but no significant relationship was found with other components of sleep quality.
Conclusion
This study suggests that daily caffeine consumption among healthcare professionals may have a positive effect on sleep duration, but does not have a significant impact on overall sleep quality.
