ABSTRACT

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease that substantially impairs health-related quality of life (HRQoL). Comorbid mental health conditions, particularly depression and anxiety, may further exacerbate this burden, yet evidence from large, population-based studies remains limited. Therefore, this study examined the association between comorbid depression and anxiety and HRQoL among adults with RA using nationally representative data from the United States. Methods: Data were drawn from the 2017–2022 Medical Expenditure Panel Survey. Adults aged ≥18 years with self-reported RA were included. HRQoL was assessed using the Veterans RAND 12-Item Health Survey (VR-12) physical (PCS) and mental (MCS) component summary scores. Multiple linear regression models were used to evaluate associations between depression, anxiety, and HRQoL, adjusting for sociodemographic, behavioral, and health-related covariates. Results: Comorbid depression and anxiety were significantly associated with lower HRQoL scores compared with RA alone. Participants with both conditions exhibited the poorest PCS and MCS scores, indicating a disease burden. Lower income, unemployment, and limited physical activity were also linked to poorer HRQoL, whereas better self-rated health and physical activity were positive predictors. Conclusions: Depression and anxiety independently and jointly contribute to poorer HRQoL among adults with RA, even after controlling for key confounders. These findings highlight the importance of integrated care models that address both psychological and physical health, alongside interventions promoting physical activity to enhance overall well-being.
