Influence of sleep posture to children with obstructive sleep apnea hypopnea syndrome / 解放军医学杂志

ABSTRACT

Objective To find out the differences of sleep posture between normal children and those with obstructive sleep apnea hypopnea syndrome(OSAHS),and assess the effects of sleep posture on the children with OSAHS.Methods The results of polysomnography(PSG) of 385 children diagnosed as OSAHS by polysomnography were compared with that of 161 children who matched the former in age and gender(Controls).The effects of different sleep posture on obstructive apnea,hypopnea index(AHI) and apnea index(AI) were analyzed.Results For the children with OSAHS when sleeping,the percentages of sleep time in different posture were 45.4%+36.3% in supine posture,39.5%+34.5% in side posture and 15.1%+32.6% in prone posture,respectively;while in control group,the correspond percentages were 32.8%+24.5%,54.7%+23.9% and 12.5%+17.2%,respectively.Comparing the two groups,significant differences existed on the sleep time in both supine and side posture(P0.05).Children with OSAHS spent more time in supine posture and less time in side posture than those children in control group(P0.05).For the children with OSAHS,the average AHI and obstructive AI in three sleep-related postures were 14.5 and 3.80,respectively.The values of both AHI and AI in supine posture were significantly greater than that in side or prone posture(P
