Objective: To explore the factors that contribute to the anxiety and depression in obstructive sleep apnea hypopnea syndrome (OSAHS) patients in terms of excessive daytime sleepiness (EDS) and sleep quality. Methods: A total of 196 OSAHS patients, including 103 severe patients and 93 mild-moderate patients, were enrolled. Polysomnography was carried on at the sleep center of the First Hospital of China Medical University between May 2013 and November 2015. According to the Epworth sleepiness scale (ESS) and the subject daytime sleepiness symptom, all patients were divided into EDS group and non-EDS group. The patients' general information and subjective symptoms were recorded. Emotional states were assessed with self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Sleep quality was evaluated with Pittsburgh sleep quality index (PSQI). The anxiety and depression related factors were studied by regression analysis. Results: (1) In severe OSAHS group, the patients with EDS showed higher PSQI(6.22±2.57 vs. 4.05±3.72, P<0.01) and oxygen desaturation index(ODI)[(57.70±17.53) events/h vs. (48.23±22.01) events/h, P<0.05] when compared with those without EDS. (2) In both severe and mild-moderate OSAHS groups, the patients with EDS presented higher SAS scores (severe: 33.86±7.60 vs.28.95±4.71, mild-moderate: 37.46±10.68 vs. 33.40±11.07, P<0.05) and SDS scores (severe: 32.81±8.36 vs. 28.90±4.53, mild-moderate:36.98±12.77 vs. 31.70±10.94, P<0.05) when compared with those without EDS. (3) The multiple regression analysis showed that the SAS scores were related to ESS, PSQI, insomnia and nasal obstruction (R(2)=0.356, P<0.05), and the SDS scores were related to ESS, PSQI and insomnia(R(2)=0.344, P<0.05). Conclusions: The anxiety and depression of OSAHS patients are closely related to the severity of EDS and sleep quality. Both severe and mild-moderate OSAHS patients with EDS have worse anxiety and depression scores.
