Examining the Association Between MIS-C and the Child Opportunity Index at a Single Center
OBJECTIVE: To describe associations between the Child Opportunity Index (COI) and multisystem inflammatory syndrome of childhood (MIS-C) diagnosis among hospitalized children. METHODS: We used a retrospective case control study design to examine children ≤21 years hospitalized at a single, tertiary care children's hospital between March 2020 and June 2021. Our study population included children diagnosed with MIS-C (n = 111) and a control group of children hospitalized for MIS-C evaluation who had an alternative diagnosis (n = 61). Census tract COI was the exposure variable, determined using the patient's home address mapped to the census tract. Our outcome measure was MIS-C diagnosis. Odds ratios measured associations between COI and MIS-C diagnosis. RESULTS: Our study population included 111 children diagnosed with MIS-C and 61 children evaluated but ruled out for MIS-C. The distribution of census tract overall COI differed significantly between children diagnosed with MIS-C compared with children with an alternate diagnosis (P = .03). Children residing in census tracts with very low to low overall COI (2.82, 95% confidence interval [CI]: 1.29-6.17) and very low to low health/environment COI (4.69, 95% CI 2.21-9.97) had significantly higher odds of being diagnosed with MIS-C compared with children living in moderate and high to very high COI census tracts, respectively. CONCLUSION: Census tract child opportunity is associated with MIS-C diagnosis among hospitalized children suggesting an important contribution of place-based determinants in the development of MIS-C.
