Abstract: Both the sleep apnea scale of sleep disorders questionnaire (SA-SDQ) and the Epworth sleepiness scale (ESS) were used to evaluate 25 patients with snoring and 125 patients with obstructive sleep apnea hypoventilation syndrome ( OSAHS), and scores were calculated and compared to the results of polysomnography ( PSG). Results showed that there was significant difference in scores of ESS and SA-SDQ, apnea hyponea index (AHI) and the minimal saturation of blood oxygen (LSpO2) at night between patients with OSAHS and those with snoring (P ＜ 0.05). Score of both ESS and SA-SDQ significantly correlated with AHI ( r = 0. 78 and r = 0. 66, respectively, P ＜ 0. 01 ) , i. e. , more severe of the condition, higher the scores. Score of ESS is highly consistent with clinical presentations in patients with OSAHS and can be used as preliminary screening for its diagnosis, however, use of SA-SDQ score is limited in diagnosing OSAHS due to its lower consistency.
