ABSTRACT
Background: The current study aimed to evaluate the impact of coronavirus (COVID-19) pandemic on sleep quality, insomnia, mental health and memory in the United States. Method(s): This was a cross-sectional study using publicly available database taken from Boston College COVID-19 Sleep and Well-Being Dataset. Result(s): A total of 476 subjects were included in the analysis, with a mean (SD) age of 38.8 (17.8) years. The population had a mean (SD) score of Pittsburgh Sleep Quality Index (PSQI of 6 (3.2), with 65% having the prevalence of poor sleep quality (defined as PSQ >= 5;n=311). The mean (SD) score for Insomnia Severity Index (ISI) was 6.9 (5.2), with 55 subjects (11.5%) had clinical insomnia (defined as ISI >= 15);of whom 9% had clinical severe insomnia. There were positive correlations between PSQI and ISI (r=0.76, p < 0.001;Figure 1), PROMIS fatigue scale (r=0.53, p<0.001), Generalized Anxiety Disorder-7 (GAD-7) (r= 0.46, p<0.001), and Perceived Stress Scale (PSS) (r=0.44, p<0.001). PSQI was inversely correlated to John Henryism Active Coping Scale (JHACS) and memory scale. In the multivariate regression model, JHACS, ISI, fatigue, PSS, and GAD-7 were significant predictors for PSQI, and these variables accounted for 62% of the variance of PSQI. Conclusion(s): There was a high prevalence of poor sleep quality during the COVID-19 pandemic, and it was in association with insomnia and other mental and physical well-being. This finding highlights the need to prioritize policy and public health efforts to address sleep issues, which have substantial health and economic effects for both individuals and the population at large.
