Introduction: Sleep quality has significant effects on cognitive
performance and is influenced by multiple factors such as daily habits, medication. Medical students, especially the
final year ones, suffer from poor sleep and stress at
times when heavy study workload is
required. This study examines the relationship between sleep quality and academic
performance of final year medical students.

Methods: We performed a cross-sectional questionnaire survey among 337 final year students in University of Medicine and
Pharmacy at Ho Chi Minh City (UMP). Students completed a survey regarding their subjective sleep quality (Pittsburgh sleep
quality index, PSQI), latest on-calls and sociodemographic factors, including age, sex, ethnic group, class
position. Academic grades were assessed based on the official public
transcripts of students. The data was examined
with one-tailed Spearman correlation analyses.

participants exhibited clinically relevant sleep disturbances (PSQI >5). The
average academic score and PSQI score of final year medical students in UMP

respectively. Academic performance was negative
correlated with sleep quality (rS = -0.11, p <0.05).

Conclusion: Poor sleep
quality are common among final year medical students. Those having lower sleep
qualities tends to have lower academic perfomance and vice versa. It is
necessary to raise awareness as well as devise detailed methods to improve both
sleep quality and academic performance.
