Title: Analysis of subjective sleep quality in patients with obstructive sleep apnea syndrome
Abstract: Objective To study the subjective sleep quality in patients with obstructive sleep apnea syndrome(OSAS). Methods Two hundred and seventeen patients with OSAS confirmed by an all-night (7 hrs) polysomnogram(PSG) were evaluated by Pittsburgh Sleep Quality Index (PSQI). Results According to the testing results of PSQI, 88 subjects (40.5%) were identified as sleepers (4≤PSQI8.5), and another 88 subjects (40.5%) as very poor sleepers(PSQI≥8.5). The patients' scores with sub-scales (components I to VII) of PSQI were 1.6±0.9, 1.1±1.1, 1.1±1.1, 1.4±1.2, 0.8±0.6, 0.3±0.9 and 1.9±1.1, respectively (P0.01).There were weak negative correlations between Apnea/hypopnea Index and PSQI, and some sub-scales (component I, II, III, IV, VI)(r=-0.15~0.42, P0.05 or 0.01). Conclusion OSAS patients exhibit poor sleep quality, mainly consisting of day-time dysfunction, poor subjective sleep quality and reduced sleep efficiency. However, apnea/hypopnea itself is not the main factor that influences the subjective sleep quality of the patients.
