    Abstract:
    OBJECTIVE: This study aimed to inspect the hypothesis that obstructive sleep apnea and hypopnea syndrome (OSAHS) was commonly worse in REM sleep than in NREM sleep stage, and also to analyze the relevance with the risk factors of OSAHS. METHOD: One hundred eighteen patients diagnosed as OSAHS by overnight polysomnography (PSG) were studied retrospectively. The severity of OSAHS in REM versus NREM sleep was compared. Then the patients were divided into two groups: AHI(REM) > or = AHI(NREM) group, and AHI(REM) < AHI(NREM) group, and the two groups were compared in age, sex, BMI, AHI, AHI supine, oxygen desaturation and duration of apnea. RESULT: There was no significant difference between AHI(REM) and AHI(NREM). AHI(REM)/AHI(NREM) was 1.0 +/- 0.5. A higher AHI NREM than AHI REM group was found in 55.9% of the 118 patients with OSAHS. There were no differences between the clinical and PSG founding of two groups. CONCLUSION: The severity of OSAHS is not greatly influenced by sleep stage.
