Oral Health Related Quality of Life in Juvenile Idiopathic Arthritis
Objectives: To assess oral health-related quality of life (OHRQoL) in children and adolescents with and without Juvenile Idiopathic Arthritis (JIA).
Methods: This study uses baseline data from a Norwegian longitudinal multicentre case-cohort study. Children and adolescents with JIA (n=224) were matched with healthy controls (n=224) according to gender, age, and background characteristics. OHRQoL was measured using the Early Childhood Oral Health Impact Scale (ECOHIS) and the Child-Oral Impact on Daily Performance scale (C-OIDP) among 4-11- and 12-16-year olds, respectively. Data was missing from four individuals. Caries in molars at dentin level was recorded using the dmft/DMFT. Cross tabulation and Chi Square test were used to assess percentage of participants having ECOHIS and C-OIDP score above 1 and 0, respectively and according to caries status, separately in children and adolescents with and without JIA.
Results: Among 4-11-year olds, 15.5% presented with caries in molars at dentin level both in children with JIA (n=97) and without JIA (n=97. In children with JIA, 92.3% versus 50.6 % (p<0.001) with- and without caries in molars at dentin level, reported total ECOHIS scores >1. Corresponding figures in children without JIA were 53.3% versus 41.0%. Among children with and without JIA, 56.5% and 42.9% (p<0.05) had total ECOHIS scores >1. Among adolescents 12-16 years with JIA (n= 125), 17.9% and 25.0% with and without caries in molars reported C-OIDP>0. Corresponding among adolescents without JIA (n=125) were 25.0% and 18.6%. Among adolescents with and without JIA, 26.3% versus 21.1% presented with C-OIDP>0.
Conclusions: JIA status was statistically significantly associated with total ECOHIS impacts, but did not discriminate between C-OIDP impacts. Higher proportions of children with than without dentin caries in molars reported ECOHIS impact scores >1.
