Sleep disturbance and its effect on academic performance among students of a medical college of Tripura

Abstract

Sleep deprivation is the condition of not having enough sleep; can be either chronic or acute. An average adult needs 7-9 hours of sleep each night, teenagers 9.5 hours and infants 16 hours per day. 3 College students are well known for keeping erratic sleep schedules. Sleep deprivation may have grave health consequences;ABSTRACT Background: Sleep deprivation may have grave health consequences; resulting in increasing disease morbidity and mortality. Sleep disturbance have also been affected academic performance of medical students. The objective of the study was to find out the prevalence of sleep disturbance and association between sleep disturbance and academic performance of medical students, if any. Methods: An institution based cross-sectional study was conducted in the month of March 2018 among 203 medical students of Tripura Medical College and Dr. B.R.A.M. Teaching Hospital. Probability Proportionate to Sample Size (PPS) was used to determine the number of students required from each semester. Students selected by simple random sampling from each semester were interviewed by a pre-designed, pre-tested interview schedule designed based on Pittsburgh Sleep Quality Index. Data was represented in percentages in tables, charts and Chi square test was applied. P<0.05 was considered statistically significant. Results: Mean age of the medical student was 21.36±1.96 years. Present study showed, 57% students were complaining of disturbed sleep. Students who felt sleepy during daytime (72.4%) were struggling more during exam compared to students not feeling sleepy (51.7%), which was statistically significant. Study revealed, students who got average mark in last semester exam were most affected with disturbed sleep (66.3%) followed by students who got good marks (53.5%) and poor marks (50%). Conclusions: Prevalence of sleep disturbance was very high among medical students. Male students were much more affected compared to female students. Sleep disturbance has also affected academic performance of students.

A comparative study of sleep quality in different phases of the medical course: A study from Haryana (North India)

“…The results for the sleep duration component revealed that the maximum (34.3%) participants were sleeping for 5-6 hours per night while 28% of participants were sleeping for less than 5 hours. Similarly, daily sleeping hours of 4-6 hours were reported by 69.38%[ 19 ] and 70.9%[ 20 ] participants in other studies. Also, 68.0% of the participants reported sleeping for 6-7 h per night in another study.…”

Nighttime Sleep Awakening Frequency and Its Consistency Predict Future Academic Performance in College Students

“…Velten-Schurian et al [80] found that in children diagnosed with insomnia, those with more parent-reported nighttime awakenings tend to exhibit more daytime sleepiness. It has been previously reported that college students' daytime sleepiness is associated with GPA [40,84] and exam struggling [85]. The current study revealed that college students who have more difficulties staying awake throughout the day tended to get lower current and future GPAs, indicating the predictive power of daytime sleepiness in concurrent and future academic performance.…”

Sleep Quality, Day Time Sleepiness and Academic Performance in First Year Medical Students

“…Study by Datta A et al revealed that students who got average mark in last semester exam were most affected with disturbed sleep (66.3%) followed by students who got good marks (53.5%) and poor marks (50%) which was statistically significant. [19] Lund HG et al reports that hyperarousal of autonomic nervous system and overactivation of hypothalamic-pituitary-adrenal axis can predispose; stressful events such as examinations and relationship problems can precipitate, and rumination and worry can perpetuate the sleep problems. [20] The present study, with 71 female and 67 male students revealed a significant association between gender and academic achievement, with the female students having better academic achievement, but no significant difference in level of sleep disturbance was found between female and male students.…”
