Abstract

Background: Juvenile Idiopathic Arthritis (JIA) is a rare case in Asia, including Indonesia. Objective: Analyze the correlation between age, sex, and symptoms on the number of joint problems in children with JIA symptoms. Methods: This study used a retrospective design from January 2016 to December 2019. The data collecting in this study was included age, sex, symptoms, and the number of joint problems. The analysis used was multiple linear regression with p <0.05. Results: The correlation between sex (β = 0.015; 95% CI -0.002 -0.002; p = 0.916), age (β = 0.015; 95% CI -0.197 -0.291; p = 0.916) to the number of joint problems was not significant. While, the correlation between symptoms and the number of joints with problems was significant, which included swelling (β = 1.012; 95% CI 0.243 -1.782; p = 0.011), fever (β = 1.000; 95% CI 0.082 -1.918; p = 0.034), and pain. (β = 0.931; 95% CI 0.082 -1.918; p = 0.007). Conclusion:There is a significant relationship between symptoms and the number of problem joints while age and sex are not significant.
