Purpose
To examine the congruence between polysomnography obstructive apnea hypopnea index (OAHI) and parent-reported obstructive sleep apnea (OSA) symptoms in 6- to 11-year-old children with juvenile idiopathic arthritis (JIA) and controls; and to compare fatigue and quality of life in JIA and control children based on OAHI and OSA symptoms.
Methods
Sixty-eight children with JIA and 75 controls and a parent participated. Children underwent one night of polysomnography in a sleep laboratory. Parents completed the sleep-related breathing disorders scale—pediatric sleep questionnaire (PSQ), and both children and parents completed the Pediatric Quality of Life Generic Core Scale and the Multidimensional Fatigue Scale.
Results
In JIA, 86% who met the OAHI clinical criteria for OSA (≥1.5) were above the PSQ OSA symptom cut-off score with a sensitivity of 0.86 and a specificity of 0.28. In the control group, 63% who met the OAHI clinical criteria for OSA were above the PSQ OSA symptom cut-off score, with a sensitivity of 0.63 and a specificity of 0.42. All children above both the clinical criteria for OAHI and OSA symptom cut-off score had the most impaired quality of life and greater fatigue compared to those below both the clinical criteria for OAHI and the OSA symptom cut-off score.
Conclusion
Children who meet clinical criteria for OSA and also scored high on a parent-reported screening tool for OSA symptoms had the most impaired quality of life and more fatigue. The PSQ has potential to identify children at risk for OSA.
