Health improvement is a multidimensional process requiring attention to both health levels and equity. This study examined nationwide trends in both the levels and equality of health-related quality of life (HRQoL) of Chinese residents during the COVID-19 pandemic (2021-2023). Data were extracted from the Psychology and Behavior Investigation of Chinese Residents (PBICR) survey: 9,963 participants in 2021, 28,280 in 2022, and 45,003 in 2023. HRQoL was assessed using the EQ-5D-5 L. Changes in the weighted average EQ-5D-5L utility index (UI) and visual analogue scale (VAS) scores were assessed. OLS regression models were used to verify the changes in UI and VAS scores over time, controlling variations in other variables. The Erreygers Index (EI) was calculated to measure inequality in UI and VAS scores. RIF-EI-OLS models were employed to decompose contributors to EI scores. There was a slight decline in HRQoL over the study period, with 2021 showing the highest weighted average UI score (0. 9363 +/- 0. 1389), compared to 0. 9332 (SD = 0. 1524) in 2022 (β=-0. 0081, P
