BackgroundIn both adults and children obstructive sleep apnea (OSA) has significant adverse cardiovascular consequences. In adults, sleeping position has a marked effect on the severity of OSA, however the limited number of studies conducted in children have reported conflicting findings. We aimed to evaluate the effect of sleeping position on OSA severity and the cardiovascular consequences in preschool-aged children.MethodsThis was a retrospective analysis of children (3-5 y) diagnosed with OSA (n=75) and non-snoring controls (n=25). Sleeping position was classified as supine, semi-supine, left lateral, right lateral, prone and semi-prone using video recordings during one night of attended polysomnography. OSA severity and cardiovascular parameters were compared between positions.ResultsAll children spent significantly more sleep time supine than in any other position. The obstructive apnea hypopnea index was higher in the supine position compared with the other sleeping positions during NREM (p<0.05), and higher in the moderate/severe OSA group when sleeping supine compared with left and right lateral (p<0.05 for both), and prone (p=0.007) during REM. Sympathovagal balance was decreased in children with OSA when in the supine and lateral positions (p<0.05).ConclusionsThis study identified that preschool-aged children, whether non-snoring controls or children with OSA, sleep predominately in the supine position, and that OSA was more severe in the supine position. We suggest that to avoid the supine sleep position, positional therapy has the potential to ameliorate OSA severity and the known cardiovascular consequences.
