Accuracy of Parental Perception of Nighttime Breathing in Children with Down Syndrome.

Objective In 2011, the American Academy of Pediatrics published a guideline for children with Down syndrome (DS), recommending a polysomnogram (PSG) by age 4 years regardless of symptoms. Their rationale was based on 2 publications with small cohorts, where at least 50% of the children had no obstructive sleep apnea (OSA) symptoms but their PSG results were abnormal. The American Academy of Otolaryngology-Head and Neck Surgery Foundation published a clinical practice guideline recommending PSG prior to adenotonsillectomy for these children. This study aimed to assess parents' accuracy of their children's breathing patterns as compared with PSGs in a larger cohort of children with DS. Study Design Case series with chart review. Setting Tertiary care academic pediatric hospital. Subjects and Methods Sleep intake forms assessing frequency of parent-observed apnea, snoring, and restless sleep were analyzed. None of the children had a previous tonsillectomy. Two groups were analyzed according to symptoms: infrequent (<3 nights per week on all questions answered) and frequent (≥6 nights per week on at least 1 question). OSA severity was categorized as follows: normal, <2 events per hour; mild, 2 to 4.9; moderate, 5 to 9.9; and severe, ≥10. Results A total of 113 children met inclusion criteria: 34% (n = 38) had infrequent symptoms, and 66% (n = 75) had frequent symptoms. Parents were unable to predict the presence or absence of OSA by nighttime symptoms ( P = .60). The risk of OSA for children with frequent symptoms versus those with infrequent symptoms was 1.04 (95% CI, 0.89-1.3). Conclusion Parents of DS children are unable to predict the presence or absence of OSA by nighttime symptoms, nor are they able to determine its severity.
