Prevalence of chronic fatigue syndrome and its related factors in covid- 19 patients discharged from at northwest of Iran hospitals in 2022

Introduction: The COVID-19 pandemic has been a tragedy. It has devastated the health and financial well-being of many people around the world. Fatigue is one of the common symptoms and complications of covid-19, which can continue in patients for a long time after infection. The present study was also conducted with the aim of determining the prevalence of chronic fatigue syndrome and associated risk factors in covid-19 patients discharged from at northwest of Iran hospitals in 2022 Methods This cross-sectional study was performed between May 2021 and January 2022 at northwest of Iran. 422 patients who had been discharged from hospital with COVID-19 were enrolled in our study. Chalder fatigue Assessment Scale (FAS) was used to measure post-COVID-19 chronic fatigue syndrome. Central and dispersion indicators were used to describe clinical and sociodemographic characteristics of patients. The chi-square test and person correlation were used to examine the statistical association between the CFS score and other clinical and sociodemographic factors. Results in overall, 72% of patients were female. The mean ± SD of the CFS score was 21.2 ± 9.0. The prevalence of post-COVID-19 CFS among our studied sample was %12.64. The findings showed that the prevalence of chronic fatigue and fatigue scores were higher in women (%13) than in men (%12.3) and this difference was statistically significant (P < 0.04). The findings showed that the prevalence of chronic fatigue with history of previous disease (P = 0.04), history of drug use (P = 0.01), history of smoking (P = 0.04), history of mechanical ventilation (P = 0.05) and age (P = 0.001) has a significant relationship. Conclusion Post-COVID-19 fatigue is a major issue following the initial acute illness with COVID-19, with a prevalence of %12.64. Therefore, the implementation of standardized measures for the screening of chronic fatigue after covid-19 and planning by the health staff in order to help these patients especially among female patients Seems necessary.
