RESUMEN
COVID-19 patients may experience varying degrees of symptom severity, significantly impacting the health-related quality of life. As a result, the current study examines the impact of symptom severity on health-related quality of life among Saudi adult COVID- 19 patients. In this cross-sectional study 310 adult COVID-19 patients were recruited through a snowball technique in Saudi Arabia. We used a questionnaire (SF-12 RAND tool questionnaire) that included three parts: sociodemographic factors, perception of degree severity of COVID-19 symptoms, and health-related quality of life (HRQoL). Out of 310 COVID-19 adult patients, 200 (64.5%) were female, 110 (35.5%) were between 30-49 years old. The mean scores of the HRQoL, physical components summary (PCS), and mental components summary (MCS) were 58.11±17.02, 71.32±23.72, and 44.91±17.94, respectively. Patients with very severe symptoms had the lowest HRQoL mean rank (120.39, P=0.023). There was a strong positive correlation between HRQoL and PCS (0.852) and HRQoL and MCS (0.730). However, PCS and MCS had a weak positive correlation (0.292). The severity of COVID-19 symptoms had a significant impact on HRQoL. Thus, it is essential to enhance the uptake of vaccines to decrease the risk of infections and avoid impact on quality of life.
