Abstract
The association between tea consumption and the duration of COVID-19-related symptoms remains inconclusive. This cross-sectional study aims to investigate the potential mediating role of sleep quality in this association.
Methods We conducted a cross-sectional study using data from elderly individuals aged 50 and above in Weitang Town in 2023. Detailed information on tea consumption, duration of COVID-19-related symptoms, and sleep quality was collected using pre-designed questionnaires. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Spearman correlation analysis was employed to examine the relationships between variables. Mediation effect analysis utilized a mediation model with multi-category independent variables.
