Kim YR 2019 UL http://www.jrheum.org/content/early/2019/11/25/jrheum.190644.abstract AB Objective To examine the risk of type 1 diabetes (T1D) associated with juvenile idiopathic arthritis (JIA). Methods Using IBM MarketScan database, we compared JIA patients with asthma patients and healthy individuals for the risk of incident T1D. Results We included 15,210 JIA, 76,050 asthma and 76,050 healthy individuals 1:5 matched on age, sex, and index date. After adjusting for confounders, multivariable hazard ratio (95% confidence interval) of T1D associated with JIA was 1.48 (0.86-2.56) versus asthma and 1.81 (1.03-3.17) versus healthy individuals. Conclusion JIA appears to be associated with an increased risk of T1D compared to asthma and healthy children.
