- Abstract: Body position has a significant impact on sleep apnea （OSA）. The objective of this study was to compare the clinical features and PSG parameters between postural OSA （POSA） and non-postural OSA（NPOSA）.Methods A total of 403 OSA patients were enrolled in this study. Before examination，clinical data were collected and subjective scales（Epworth Sleep Scale，Berlin Questionnaire，and StopBANG questionnaire） were evaluated，and PSG parameters of 403 OSA patients were recorded in the sleep laboratory. The differences between POSA group and NPOSA group were compared. Results 170 subjects（42.2%） met the diagnostic criteria of POSA.The neck circumference and BMI of POSA patients are lower than those of NPOASA patients（P<0.05）.In POSA group，the time in N1 sleep stage is significantly shortened，but the time in N2，N3 and REM sleep stages are longer （P<0.05）.AHI，micro-arousal index，leg movement index and periodic leg movement index of POSA group are lower than those of NPOSA group，and the differences are showed statistically significant（P<0.05 or P<0.01）.In addition，the fastest heart rate in POSA group is lower than that in NPOSA group in both waking and sleeping periods（P<0.05）.Conclusions The results of POSA group and NPOSA group show different clinical characteristics.The POSA patients have better sleep structure，while the NPOSA patients have worse sleep structure and may bear more heart risks.
