| 摘要: |
| 目的 了解北极特殊环境对科考队员睡眠质量的影响。方法 应用匹兹堡睡眠质量指数（PSQI）量表对参加我国第9次北极科学考察的科考队员（131人）在出行前、北极考察期间、考察结束后的睡眠情况进行调查，并记录队员的入睡时间点、晨起时间点、入睡时间、睡眠时间。结果 共发放问卷131份，回收有效问卷88份。88名队员中男77名、女11名，年龄为22~50（48.1±17.9）岁，包括船员18人、科考队员70人。考察期间队员的中位晨起时间点比出行前早180 min，入睡时间长于出行前及考察结束3个月后[（45.23±25.84） min vs （18.45±14.34） min、（19.50±12.57） min，P均<0.01]，夜晚睡眠时间短于出行前及考察结束3个月后[（6.83±2.24） h vs （8.36±1.45） h、（8.14±1.45） h，P均<0.01]。根据PSQI量表评分，考察期间队员的睡眠质量下降、入睡时间延长、睡眠时间缩短、睡眠效率下降、催眠药物使用增加，与出行前相比差异均有统计学意义（P均<0.01）。结论 极地极昼及低温环境显著影响北极科学考察时科考队员的睡眠节律，导致入睡时间延长、睡眠时间缩短、助眠药物使用增加，这可能影响到队员的工作状态。 |

| Abstract: |
| Objective To understand the influence of Arctic environment on sleep quality of expeditioners. Methods Pittsburgh sleep quality index (PSQI) scale was used to investigate the sleep statuses of the 131 expeditioners for the China's 9th Arctic research expedition before, during and after the expedition, and the sleep time point, morning rise time, sleep latency and actual sleep time were recorded. Results A total of 131 questionnaires were sent out, and 88 valid questionnaires were collected from 77 males and 11 females, aged 22-50 (48.1±17.9) years, including 18 crew members and 70 scientific research team members. During the expedition, the median morning rise time was 180 min earlier than that before the expedition, the sleep latency was longer than that before and 3 months after the expedition ([45.23±25.84] min vs[18.45±14.34] min and[19.50±12.57] min, both P<0.01), and the sleep time at night was shorter than that before and 3 months after the expedition ([6.83±2.24] h vs[8.36±1.45] h and[8.14±1.45] h, both P<0.01). According to the score of PSQI scale, the sleep quality was decreased, the sleep latency was prolonged, the sleep time was shortened, the sleep efficiency was decreased and the use of hypnotic drugs was increased during the expedition, with significant differences as compared with those before the expedition (all P<0.01). Conclusion Polar day and low temperature environment significantly affect the sleep rhythm of expeditioners, prolonging the sleep latency, shortening the sleep time and increasing the use of hypnotic drugs, which may affect the working state of expeditioners. |
