Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disease resulting in physical and psychological disability. This study aimed to measure the health-related quality of life (HRQOL) and identify factors influencing the HRQOL.
We conducted a cross-sectional study in Thai children with JIA and their parents between January and December 2015, using the Thai version of the Pediatrics Quality of Life (PedsQL) 4.0 generic core scale.
Sixty-five children (33 girls and 32 boys) were included. The median age of the children was 9.6 (interquartile range [IQR] 6.4-12.3) years and the median disease duration was 1.1 (IQR 0.2-2.2) years. The physical health subscale had the lowest score, with a median (range) of 78.1 (34.4-100). Twenty-five (45.4%) children were classified as having suboptimal HRQOL. The school functioning subscale had the lowest score, at 60 (25-100) reported by parents. High disease activity and a disease duration <1 year were significantly associated with suboptimal HRQOL reported by parents, with adjusted odds ratios (ORs) of 20.2 (95% confidence interval [CI] 1.4, 291.7) and 5.9 (95% CI 1.2, 33.3), respectively.
Almost half of Thai children with JIA had suboptimal HRQOL. The physical health score was the lowest subscale reported by the children. Early, effective management of disease activity could improve the HRQOL in children with JIA.
