Title: Abstracts: Pediatric Rheumatology – Clinical (0974–0979)

Session Type: Abstract Session

Session Time: 2:30PM-2:45PM

Background/Purpose: The impact of social determinants of health in juvenile idiopathic arthritis (JIA) remains poorly understood. Racial disparities exist in JIA, including increased pain and joint damage among Black and Latinx children. Adverse childhood events (ACEs) have been associated with increased odds of childhood arthritis, suggesting an association with chronic stress exposure. However, studies on the impact of poverty and insurance status have yielded mixed results. Data suggests social risk may have a cumulative impact on health, with recent analyses using combined scoring systems to measure social determinants of health. Our aim was to calculate a cumulative social risk score (including income, race/ethnicity, education, and ACE data) and assess its association with arthritis in the National Survey of Children’s Health (NSCH).

Methods: This is a cross-sectional analysis utilizing the 2017-2018 version of the NSCH, a federally administered survey focused on physical and emotional health of children 0-17 years of age in the US. Social risk score was generated, with a score of 1 given for each of the following domains: education (high school or less), income level (0-199% of Federal Poverty Level), insurance status (public or uninsured), and high ACE score (4). The cohort was dichotomized by the presence of currently reported arthritis and compared using descriptive statistics (Kruskal Wallis and Pearson’s chi-squared or Fisher’s exact tests, as appropriate). Univariate and multivariate logistic regression were used to measure the impact of social risk score on the odds of an arthritis diagnosis, controlling for age, sex, and race/ethnicity. An analogous method was used to investigate parent-reported severity of arthritis (moderate/severe versus mild) within the arthritis cohort.

Results: 146 children reported current arthritis, yielding a population estimate of 199,725 children using appropriate survey weights (Table 1). Families of children with arthritis reported lower income (40% vs 28%), lower education level (27% vs 15%), greater likelihood of having public insurance or being uninsured (40% vs 24%), and greater likelihood of having an ACE score ≥4 (16% vs 7%), as compared to children without arthritis (p-value < 0.001). In multivariate logistic regression, higher social risk score was predictive of an arthritis diagnosis (Table 2, p=0.009) with highest odds among those with a score of 3 (adjusted OR 3.93, p=0.002). Among the arthritis cohort, social risk score predicted increased parent-reported arthritis severity (Table 3), though this was not statistically significant (p=0.2).

Conclusion: In this nationally representative sample, children with arthritis were more likely to come from households with lower income and education level and were more likely to have public insurance or be uninsured, yielding higher social risk scores than their peers without arthritis. In adjusted analysis, social risk factors predicted increased odds of an arthritis diagnosis. There was a trend towards increased parent-reported severity of arthritis among children with more social risk, though this finding did not achieve statistical significance.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
