Comorbidity patterns before and after juvenile idiopathic arthritis diagnosis

Abstract

Employing Oracle Real-World Data, this study examined demographic characteristics and comorbidity patterns in Juvenile Idiopathic Arthritis (JIA) patients before and after diagnosis. We found disparities in diagnosis age across racial groups. Pre-diagnostic indicators like musculoskeletal pain—especially alongside joint, abdominal, or respiratory symptoms—may serve as early clinical signs. Post-diagnosis, the comorbidity burden expanded to broader multi-system involvement, predominant in joint, skin, and respiratory conditions.
