Impact of Cumulative Social Disadvantage on Disease Severity in Juvenile Idiopathic Arthritis: Findings from a Childhood Arthritis and Rheumatology Research Alliance Registry Analysis
To assess the associations between individual, family, and community-level social determinants of health (SDOH) and disease activity in children with juvenile idiopathic arthritis (JIA).
Approach:
Study Design: A retrospective cohort study using data from the CARRA Registry, focusing on children with JIA in the United States.
Cumulative Social Disadvantage Score: Developed a score based on household SDOH, including insurance status, income level, and guardian education.
Neighborhood Deprivation: Analyzed neighborhood-level deprivation using the Area Deprivation Index (ADI) as a separate exposure.
Causal Mediation Analysis: Performed analysis to investigate neighborhood disadvantage as a mediator of the cumulative social disadvantage score's effect on disease activity.
Key Findings:
Cumulative social disadvantage was strongly associated with higher disease activity in children with JIA.
Neighborhood-level deprivation (ADI) was found to mediate the relationship between cumulative social disadvantage and disease activity.
Interpretation:
Limitations:
The study did not measure societal-level factors that could impact outcomes.
Changes in SDOH over time were not assessed as exposures were evaluated only at enrollment.
