IJCM_164A: Association between Sleep Quality and Short-Term memory among medical students in mangalore

Abstract

Background: Sleep plays a crucial role in maintaining cognitive functions, including memory, which is essential for academic performance. However, there is limited research exploring the relationship between sleep quality and short-term memory among medical students. Methodology: Fourth-semester MBBS students from Kasturba Medical College, Mangalore, were selected using non- random convenience sampling. A total of 195 students participated, completing a standardized sleep quality assessment (Pittsburgh Sleep Quality Index) and a semi-structured self-administered questionnaire-based short-term memory test. Data were analyzed using SPSS version 16, with correlation tested using Karl Pearson’s Coefficient of Correlation Test. Results: The majority (56.4%) of participants exhibited good sleep quality, with 69.1% of these achieving high scores in short-term memory assessment tasks. A negative correlation (r = -0.450, p < 0.001) was found between sleep quality and short-term memory scores. Students with good sleep quality were more likely to have higher short-term memory scores compared to those with poor sleep quality. Conclusion: The study suggests that good sleep quality is associated with better short-term memory performance among medical students. These findings underscore the importance of promoting good sleep habits to enhance cognitive function and academic performance in medical education.
