ABSTRACT
Objectives: Due to the long-lasting pandemic measures, such as lockdown and stay-at-home orders, the COVID-19 pandemic has had a negative impact on higher education. In this study, we aimed to determine sleep quality, excessive daytime sleepiness, and sleep hygiene, and their association with anxiety, and their correlation in preclinical medical students during the COVID-19 pandemic. Materials and Methods: We included 101 medical students, aged between 17-20 years of both sex from a tertiary care medical institute. Standard questionnaires were used to assess sleep quality, sleep hygiene, daytime sleepiness, and anxiety among medical students. Results: Fifty-one percent of the medical students had good sleep quality, but 35% had borderline poor sleep quality, and 13% had poor sleep quality during the lockdown. Six percent of medical students had alarmingly high daytime sleepiness. The total Adolescent Sleep Hygiene Scale (ASHS) score was grouped into poor sleep hygiene (ASHS score ≤ 3.8) and good sleep hygiene (ASHS score ≥ 4.9). Overall, sleep hygiene of medical students was poor due to behavioral arousal and bedtime routine factors, and the scores for anxiety and sleep hygiene were significantly negatively correlated, whereas daytime sleepiness showed a significant positive correlation. Conclusion: Our study revealed a high prevalence of poor sleep quality among medical students during the lockdown. Poor sleep hygiene is an eye-opener for the mostly ignored aspect of altered sleep patterns.
