WITHDRAWN: The Prevalence of Insomnia Symptoms and Its Association With Quality of Life Among Clinically Stable Older Patients With Psychiatric Disorders in China During the COVID-19 Outbreak

Abstract

Aims: The negative impact of the COVID-19 outbreak on sleep quality of clinically stable psychiatric patients is unknown. This study examined the prevalence of insomnia symptoms and its association with quality of life (QOL) in clinically stable older psychiatric patients during the COVID-19 outbreak. Methods: This multicenter, cross-sectional study involved older patients attending maintenance-treatment at the outpatient departments of four major psychiatric hospitals in China. Patients’ basic socio-demographic and clinical characteristics were collected. Insomnia symptoms, depressive symptoms, and QOL were assessed with the Insomnia Severity Index (ISI), Patient Health Questionnaire (PHQ-9), and two items of the World Health Organization Quality of Life-brief version (WHOQOL-BREF), respectively. Binary logistic regression analysis was conducted to examine the independent associations of socio-demographic and clinical variables with insomnia symptoms, while the association between insomnia symptoms and QOL was examined with analysis of covariance.Results: A total of 941 patients were recruited. The prevalence of insomnia symptoms was 57.1% (95% CI: 53.9-60.2%). Analysis of covariance revealed that QOL was significantly lower in patients with insomnia symptoms compared to those without them (P<0.01). Multivariate logistic regression analysis showed that insomnia symptoms were positively and independently associated with more severe depressive symptoms (P<0.01, OR=1.31, 95%CI: 1.26-1.37). Compared to patients with major depressive disorder, those with other psychiatric diagnoses had significantly higher prevalence of insomnia symptoms (P=0.03, OR=1.47, 95%CI: 1.02-2.12).Conclusions: Insomnia symptoms were common among clinically stable older psychiatric patients during the COVID-19 outbreak. Considering their negative impact on QOL, regular assessment and treatment of insomnia symptoms need to be addressed in this population.
