Abstract

Background

Sleep health is a broad concept that refers to a person’s ability to get enough quality, consistent sleep to engage in daily

activities with vigor and productivity. It covers not only the duration and quality of sleep but also many other factors, such

as sleep patterns, attitudes towards sleep, sleep environment conditions, and quality of recovery. This study aims to assess

the quality of sleep in medical students and determine whether it correlates with academic success.

Methods

A total of 136 medical students were included in the study, and their sleep quality was assessed using the Pittsburgh Sleep

Quality Index (PSQI). We also collected the participants’ 1st semester GPAs and analyzed the relationship between sleep

parameters and academic achievement.

Result

42% of participants had poor sleep quality on the PSQI, with a quarter taking longer than 30 minutes to fall asleep and

25% sleeping less than 6 hours per night. 92.6% of the students surveyed had a GPA below 3.0, and among them, poor

sleep quality was found to be a high percentage. Here, the highest percentage is 44.9%, and those who score “1.00” have

“normal” sleep. Then 3.7% gave a score of “3.00”, which means that they had very poor quality sleep. The mean PSQI of

students with a 2.0 GPA was 8.59±3.06, 8.40±3.32 of students with a 3.0 GPA, and 7.00±2.62 for students with a 4.0 GPA,

and no statistically significant difference was observed (p=0.376).

Compared to the level of the course studied, the average score of PSQI was 8.27±3.01 in the 1st course, 8.37±3.58 in the

2nd course, 10.00±4.24 in the 3rd course, and 9.50±4.95 in the 5th course. The difference between the channels was also

not statistically significant (p=0.921).

Conclusion

Poor sleep quality among medical students is directly related to their academic performance. Therefore, it is necessary to

implement support, training, and preventive measures based on students’ sleep patterns.
