Depressive symptom and correlative factors in patients with obstructive sleep apnea-hypopnea syndrom

Objective To investigate the depression and its influencing factors in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods The scales of the demographic data,Epworth sleepiness scale (ESS),Pittsburgh sleep quality index (PSQI),Beck depression inventory(BDI),and simplified coping style questionnaire (SCSQ) were tested in 114 patients with OSAHS. Results The BDI score was (8.29±6.46),and 32.5% of the patients had depression. The BDI score was related to the coping style,PSQI total score and the subjective sleep quality,sleep time,sleep efficiency,sleep disturbance,using hypnotic drugs,and day-time dysfunction. There were no correlations between the ESS,body mass index,apnea hyponea index(AHI),lowest oxygen saturation (LSaO2),mean oxygen saturation (MSaO2) and depression.Conclusion About 1/3 of the OSAHS patients have depressive symptoms. PSQI score,negative coping style,positive coping style,using hypnotic drugs,and time for falling asleep are influential factors in OSAHS patients.
