Factors associated with quality of life in long-COVID syndrome
该研究调查了53名长新冠患者，发现疲劳和心理困扰解释了生活质量42%的变异，而认知障碍与生活质量无关。
Approximately 10% of patients experience persistent symptoms following COVID-19, known as long-COVID syndrome. This cross-sectional study explored factors of quality of life (QoL) in 53 long-COVID patients. QoL was measured using the World Health Organization-Five Well-Being Index, fatigue with the Fatigue Visual Analogue Scale, and psychological health with the Depression-Anxiety-Stress-21 questionnaire. Six neuropsychological tests assessed information processing speed, verbal memory, visual memory, working memory, attention, language, fluency, recall, and visuospatial function with a composite score calculated by averaging z scores. Patients (76% female, mean age: 54.1 years) were assessed 8.7 months postinfection. Cognitive impairment, present in 49% of the sample, was not associated with QoL. In multiple linear regression, gender, fatigue, and psychological distress accounted for 42% of QoL variance, with fatigue and distress contributing 7% and 11%, respectively. Further studies are needed to determine if fatigue and psychological distress are causally related to QoL in long-COVID and could be treatment targets.
