Children may present sleep-disordered breathing (SDB) and suffer with adverse effects upon their quality of life.


This study assessed the quality of life of children with SDB, compared subjects with obstructive sleep apnea syndrome (OSAS) and primary snoring (PS), and identified which areas in the OSA-18 questionnaire are more affected.


This is a historical cohort cross-sectional study carried out on a consecutive sample of children with history of snoring and adenotonsillar hyperplasia. The subject's quality of life was assessed based on the answers their caregivers gave in the OSA-18 questionnaire and on diagnostic polysomnography tests.


A number of 59 children participated in this study with mean age of 6.7 ± 2.26 years. The mean score of the OSA-18 was 77.9 ± 13.22 and the area most affected were "caregiver concerns" (21.8 ± 4.25), "sleep disturbance" (18.8 ± 5.19), "physical suffering" (17.3 ± 5.0). The impact was low in 6 children (10.2%), moderate in 33 (55.9%) and high in 20 (33.9%). PS was found in 44 children (74.6%), OSAS in 15 (25.6%). OSAS had higher score on "physical suffering" area than PS (p = 0.04). The AI (r = 0.22; p = 0.08) and AHI (r = 0.14; p = 0.26) were not correlated with OSA-18.


Sleep disordered breathing in childhood cause impairment in quality of life and areas most affected the OSA-18 were: "caregiver concerns", "sleep disturbance" and "physical suffering". OSAS has the domain "physical suffering" more affected than primary snorers.
