飛行員睡眠品質與認知功能之探討
The Sleep Quality and Cognitive Function of Aircrew in ROCAF
摘要
睡眠品質不佳可能會引起疲勞的現象，導致飛行員出現草率、怠慢、注意力不集中、以及影響認知功能，進而危害飛安。然而，造成睡眠品質不佳的因素有很多，例如工作壓力、輪班工作、以及工作時數過長等。 本研究之目的在探討飛行員之睡眠品質與認知功能，以三個空軍基地的120名飛行員為研究對象（34.4±7.0歲），採用匹堡堡睡眠品質指標(PSQI)設計評估問卷，以威斯康辛卡片分類測驗(WCST)評估認知的功能。 本研究的結果顯示：睡眠品質之平均總分為4.93±2.3分；若以5分為切點區分之，則有35%為睡眠品質不佳；睡眠品質良好與睡眠不佳兩組之間有50%的WCST次項分數呈顯著差異；且PSQI的總分與50%的WCST次項分數呈顯著的相關。因此，睡眠品質對飛行員的認知功能確有影響，必須予以適當的調節，以免影響到飛安。

Introduction: Insufficient sleep could induce fatigue and cause aircrew sloppy, inattentive, inefficient, and impaired cognitive function that would threat safety. The high work pressure, shift work, and long duty cycles could be the reasons of poor sleep quality. This study is to investigate the relationship between the sleep quality and cognitive function of aircrew. Methods: One hundred and twenty health pilots (34.4±7.0 ages) voluntarily participated this project. The quality of sleep was evaluated using Pittsburgh Sleep Quality Index (PSQI). Cognitive function was assessed using Wisconsin Card Sorting Test-computer version 3 (WCST-CV3). Results: The average PSQI global score was 4.93±2.3. There were 35% of subjective classified as poor sleeper whose scores were over the cutoff point of 5. Comparing the scores of WCST between good sleeper group and poor sleeper group, we found significant difference from 50% of sub-items. Besides, significant correlation existed between PSQI and 50% of sub-items of WCST. Totally, 70% of sub-items of BSRS were also affected by the sleep quality. Conclusion: Sleep quality could affect the cognitive task of aircrew to some extent. Appropriate countermeasures will be required to improve their sleep quality for flying safety.
