飞行人员飞行前夜睡眠变化及相关危险因素调查分析

目的调查飞行人员飞行前夜睡眠变化,分析影响睡眠变化的相关危险因素。方法采取整群抽样方法对1380名飞行人员进行问卷调查,对其中1285份有效问卷进行分析。通过单因素分析和多元Logistic回归方程对睡眠变化的相关因素进行统计,应用χ2检验比较平时和飞行前夜睡眠质量的差异。结果与平时相比,62.3%的飞行人员飞行前夜睡眠发生了不同形式、不同程度的变化。其中,存在1种、2种或3种及以上任何睡眠形式变化者分别为19.3%、15.8%和27.3%。最常见的睡眠变化为夜间睡眠时间减少(30.3%)、早晨醒来时间提前(26.9%)和入睡潜伏时间延长(23.1%)。飞行前夜各种睡眠变化的危险因素为平时睡眠质量差、平时入睡潜伏时间、平时易醒、年均飞行时间和专业构成(P0.05)。平时和飞行前夜睡眠质量好、一般、差的构成比分别为80.9%、16.6%、2.5%和65.9%、29.2%、4.9%,差异具有统计学意义(χ2=292.010,P0.05)。结论飞行前夜飞行人员可发生各种形式、各种程度的睡眠变化。关注平时睡眠状况和质量是预防及调整飞行前夜睡眠变化的基础。

Survey and analysis of the sleep change and associated risk factors of aviation personnel on flight eve

Objective To investigate the sleep change of aviation personnel on flight eve and analyze the associated risk fac-tors. Methods A cluster sampling survey was performed in 1380 aviation personnel of army,navy and air force. 1285 questionnaire were available for evaluation. Univariate and multivariate logistic regression were carried out to explore the correlation between sleep change on flight eve and its relevant factors. Results Compared with usual nights,on flight eve sleep was changed in different forms and degree. In general,changes were seen in one,two and three or more aspects in 19.3%,15.8% and 27.3% aviation personnel,respectively. The most common changes included decreased nocturnal sleep duration（30.3%）,advanced awakening time in the morning（26.9%） and increased sleep latency（23.1%）. The risk factors of sleep changes on flight eve included poor sleep quality of usual nights,habitual increased sleep latency,and habitual nocturnal awakening; it also affected average annual flight time and specialty（P〈0.05）. The proportions of sleep quality on usual nights were 80.9%（good）,16.6%（moderate） and 2.5%（poor）,respectively.Whereas the proportions of sleep quality on flight eve were 65.9%（good）,29.2%（moderate） and 4.9%（poor）,respectively. The differences were statistically significant（χ2= 292.010,P〈0.05）. Conclusion On flight eve, aviation personnel may have sleep changes in different forms and degree. Paying close attention to sleep habit and sleep quality is essential to preventing and adjusting sleep changes on flight eve.
