Background: The prevalence of sleep problems is approximately 40% among the general and health-care populations. Post-covid-19 sleep disturbances may persist for a long time and are often precursors of psychiatric disorders and expeditors of many systemic diseases. Studies on sleep quality in COVID-19 patients are considerable but in post-COVID-recovered subjects are scanty. There is no study on sleep quality of such patients in Eastern India.
Aims and Objectives: We hypothesize that both sleep disturbances and sleep quality may be affected in subjects in their post-COVID state. Therefore, we planned to study the prevalence of sleep disturbances, sleep quality, severity of insomnia, and the relationship of different parameters with respect to sleep quality.
Materials and Methods: Two hundred and fifty COVID-19-recovered patients were administered a pre-structured questionnaire including Pittsburgh sleep quality index and insomnia severity index containing various sleep parameters.
Results: Majority of the study participants had sleep disturbances in the form of change in sleep pattern (59.6%), poor sleep quality (77.6%), reduced sleep duration (29.6%), daytime sleepiness (20%), difficulty in sleep initiation (29.6%), and subthreshold insomnia (53.6%). Poor sleep quality was strongly associated with reinfection, change in sleep pattern after infection, sleep pattern alteration during pandemic, and those who felt tired during daytime.
Conclusion: This study concludes that a significant number of COVID-19-recovered subjects experienced sleep disturbances including poor sleep quality.
