Association between Perceived Stress and Rhinitis-Related Quality of Life: A Multicenter, Cross-Sectional Study.

Abstract

Allergic rhinitis (AR), a common chronic disease, impairs patients’ quality of life (QoL). This study aimed to determine the effect of perceived stress on disease-related QoL in AR patients. There were 741 patients from eight medical centers of the Allergic Rhinitis Cohort (ARCO) study. Data on sociodemographics, chronic conditions, AR severity, perceived stress level and Rhinoconjunctivitis QoL Questionnaire (RQLQ) results, and laboratory test findings were collected. The relationship between perceived stress and total RQLQ was analyzed using multiple linear regression. Potential confounding variables were adjusted. A high perceived stress level was associated with a high total RQLQ, which reflected worsening disease-related QoL. The high stress level was associated with an increased total RQLQ of 1.210 (95% confidence interval, 0.831–1.589; p < 0.0001) compared with the very low level. In the final model, the multiple regression-adjusted R2 for RQLQ in AR participants was 0.5279, and perceived stress levels contributed 4.08% in additional explanatory power to RQLQ in AR patients. In conclusion, perceived stress is a potentially modifiable risk factor for decreased disease-related QoL in patients with AR, which may be improved with stress management.
