“…The current study demonstrates that optimized sleep patterns may improve academic performance and learning ability; conversely, poor sleep quality is associated with low academic performance and learning ability. These findings agree with those of a study conducted on medical students demonstrating that 38.9% of students had poor sleep quality according to the PSQI (24). In the present study, sleep disturbance is very com-mon among medical students, as reported by 66.66% of the respondents.…”

Background: Medical students are exposed to a significant level of pressure because of their academic demands. Thus, they are at increased risk for sleep disorders. Objectives: This study was conducted to examine the prevalence of sleep disturbance among medical students and investigate any relationship between sleep disorder and academic performance. Materials and Methods:This work is a cross-sectional questionnaire-based study. Participants of this study consisted of first-, second-, and third-year medical students. The Pittsburgh sleep quality index (PSQI) was adopted to identify sleep disorder, and the grade point average of the students was recorded for academic performance. Results: A total of 177 respondents, with a response rate of 55%, were obtained. According to the PSQI score, 36.6% of participants were considered to have abnormal sleep habits, with a statistically significant increase in female students (P < 0.05). Abnormal PSQI scores were associated with lower academic achievement (P < 0.05). Marital status, habitat, smoking and physical activity were also associated with PSQI scores. Conclusions: A high prevalence of sleep disorder was found in this population, specifically among female students. Analysis of the relationship between sleep disorder and academic performance indicates a significant relationship of PSQI scores with marital status, habitat, smoking, physical activity, and academic performance.

“…This finding is consistent with Medeiros et al's research among medical students that found students who reported sleeping for longer durations obtained higher scores on examinations, as well as Veldi et al's study that found sleep behaviors to be associated with academic progression. 9,10 Moreover, congruent findings of decreased sleep duration associated with poor examination performance were found in Gruber et al's study on children's performance on IQ measures and Perez-Lloret et al's study on adolescents' performance on mathematics and literature coursework. [12][13] The causal relationship between sleep duration (cause) and academic performance (outcome) cannot be established because of the nature of the cross-sectional study.…”

“…Those studies that have, found sleep complaints were common in medical students and poor sleep habits were correlated with changes in academic performance. 9,10 However, studies that provide knowledge about sleep habits among student pharmacists have yet to be conducted in the United States. Research is needed to provide student pharmacists with tangible evidence they can use to make daily decisions regarding their sleep as it relates to their academic success.…”

Objective. To identify sleep patterns and frequency of daytime sleepiness and to assess the association between sleep duration and academic performance among student pharmacists. Methods. A cross-sectional design was used. An anonymous self-administered paper questionnaire was administered to first-year through third-year students at a pharmacy school. Results. Questionnaires were completed by 364 student pharmacists (79.4% response rate and 93.8% cooperation rate). More than half of student pharmacists obtained less than 7 hours of sleep at night during a typical school week (54.7%) and a large majority on the night prior to an examination (81.7%). Almost half (47.8%) felt daytime sleepiness almost every day. Longer sleep duration the night prior to an examination was associated with higher course grades and semester grade point averages (GPAs). Conclusion. A majority of student pharmacists had suboptimal durations of sleep, defined as fewer than 7 hours. Adequate sleep the night prior to an examination was positively associated with student course grades and semester GPAs.

“…A high correlation has been demonstrated between sleep duration and performance in some activities, as well as subjective alertness (4). The importance of sleep duration was also shown in our previous study, in which we demonstrated a correlation between sleep deprivation and academic performance in medical students (5).…”

The sleep-wake cycle of students is characterized by delayed onset, partial sleep deprivation and poor sleep quality. Like other circadian rhythms, the sleep-wake cycle is influenced by endogenous and environmental factors. The aim of the present study was to determine the effects of different class starting times on the sleep-wake pattern of 27 medical students. The data were collected during two medical school semesters having different class starting times. All subjects answered the Portuguese version of the Horne and Östberg Morningness/Eveningness Questionnaire, the Pittsburgh Sleep Quality Index (PSQI) and kept a sleep diary for two weeks during each semester. Better sleep quality (PSQI = 5.3 vs 3.4), delayed sleep onset (23:59 vs 0:54 h) and longer sleep duration (6 h and 55 min vs 7 h and 25 min) were observed with the late schedule. We also found reduced sleep durations during weekdays and extended sleep durations during weekends. This pattern was more pronounced during the semester with the early class schedule, indicating that the students were more sleep deprived when their classes began earlier in the morning. These results require further investigation regarding the temporal organization of our institutions. Correspondence
