Abstract: Objective  To analyze the psychological status of patients with obstructive sleep apnea hypopnea syndrome(OSAHS).Methods  SCL90 psychological scale was used to evaluate 200 patients with OSAHS diagnosed by polysomnography(PSG) and met the inclusion and exclusion criteria. The correlation between the scores of anxiety and depression and PSG indicators was analyzed, and the relationship was discussed. Results  The overall psychological status of OSAHS patients was worse than that of normal people, and the scores of  somatization, obsessivecompulsive symptoms, interpersonal sensitivity, depression, anxiety, fear, paranoia and psychotic factors were higher than those of the domestic norm, with statistically significant differences(P<0.05).There were statistically significant differences in the psychological status of OSAHS patients with different illness degrees(P<0.05).OSAHS patients' anxiety and depression scores were positively correlated with apnea hypopnea index(AHI),microawakening index(MAI), and the time when blood oxygen saturation was less than 90% of total sleep time(TS90%)(P<0.05), and negatively correlated with LSaO2, proportion of rapid eye movement(REM) sleep and deep sleep(P<0.05).Conclusion  The overall psychological status of OSAHS patients is worse than that of normal people, and the psychological status of patients with different degrees of illness is also different. The scores of anxiety and depression were related to chronic nocturnal hypoxia, sleep fragmentation and sleep structure disorder.
