Abstract
Objective Coronavirus disease (COVID-19) pandemic has become a source of abrupt disruptions in regular sleep habits (circadian rhythms) secondary to the associated severe physical and mental health issues. However, there are no studies, to the best of our knowledge, providing evidence based information on sleep-related disorders among patients with COVID-19 from India till date. In the present cross sectional studies, we explored the prevalence of insomnia and its correlations in a COVID-19 patient population in South India. Methods A cross-sectional study was conducted among patients admitted with COVID-19 in a designated COVID-19 treatment centre. Sociodemographic and clinical details were collected according to a structured performa. Medical records were reviewed to collect information about medical background, overall medical parameters of COVID-19, laboratory values and treatment details. The insomnia was evaluated using the Insomnia Severity Index. Results The mean age of the participants was 51.59 years, and 73 (53.7%) participants were females. Twenty-three (16.9%) participants had subthreshold insomnia, and 3 (2.2%) participants had clinical insomnia. The white blood cell count was higher in the insomnia group (8.5Ã109/L) than in the non-insomnia group (6.4Ã109/L) (p=0.003). The lymphocyte count was significantly lower in the insomnia group (24.13%WB) compared with the non-insomnia group (31.41%WB) (p=0.008). The ALT, AST, and serum creatinine levels were significantly higher among the insomnia group. Conclusion Insomnia may occur among active patients with COVID-19 infection. It is important to keep in mind that there is a hidden danger of the transformation of acute insomnia into chronic insomnia among COVID-19 patients. It is important to disseminate sleep health education and sleep hygiene behavior interventions to the COVID-19 patient population while they are admitted in the hospital.
