Comparison of Biopsychosocial Characteristics of Children with Juvenile Idiopathic Arthritis According to Common Disease Subtypes.

OBJECTIVE

In this study, we assessed the functional and biopsychosocial characteristics of juvenile idiopathic arthritis (JIA) patients according to disease subtypes.

MATERIALS AND

METHODS

Child Health Assessment Questionnaire (CHAQ), Juvenile Arthritis Disease Activity Score-71 (JADAS-71), and Juvenile Arthritis Biopsychosocial Questionnaire (JAB-Q) scales were administered to 304 JIA patients, and the subscale of JAB-Q was administered to their families.

RESULTS

The median age of JIA patients at diagnosis was 7.9 (5.5-13) years (female/male = 1.3). Most patients were under treatment (68.7%) and had inactive disease (69.3%). While there was no significant difference between JADAS-71 scores according to the JIA subtypes, total CHAQ scores in polyarticular JIA patients were higher than in systemic JIA patients (P = .005). Enthesitis-related arthritis (ERA) patients had higher JAB-Q fatigue total scores compared to systemic JJIA patients (P = .001). Juvenile Arthritis Biopsychosocial Questionnaire-child psychosocial status scores were higher in polyarticular JIA patients than oligoarticular and systemic JIA patients (P = .004 and P = .003, respectively), and they had higher JAB-Q child form total scores than systemic JIA patients (P = .006). In addition, systemic JIA patients' parents had higher JAB-Q family total scores compared to oligoarticular JIA patients' parents (P = .03).

CONCLUSION

Our results suggest that polyarticular JIA patients had higher CHAQ, JAB-Q psychosocial status, and child form total scores, and the JAB-Q fatigue score was higher in ERA patients. Also, JAB-Q-parent scores were higher in systemic JIA patients' parents. Biopsychosocial characteristics should be evaluated in both JIA patients and their parents.
