摘要目的 对长时问远洋单舰艇航行的我海军官兵不同时间点睡眠障碍情况进行调查分析.方法 在我海军某舰执行远洋任务期问,分别在第1、2、3、4个月,向150名官兵发放匹兹堡睡眠质量指数(Pittsburgh sleep quality index,PSQI)表,自我评价睡眠质量.结果 102名官兵完成调查问卷,第1～4个月的PSQI评分分别为4.09 ±2.23,5.87±2.09,7.26±3.32和7.71 ±3.87,各月问比较差异有统计学意义(P＜0.01);以评分＞7分为睡眠障碍的界点,4个月睡眠障碍所占人数比例分别为29.4％、34.3％、47.1％和48.0％,各月间比较差异有统计学意义(P＜0.01);睡眠质量、入睡时间、睡眠效率、睡眠障碍和日间功能障碍几个因素各月分值比较差异有统计学意义(P＜0.01);PSQI评分和年龄、文化程度、职位(军官或士兵)和服役时间无明显的相关性(P＞0.05).结论 该次单舰远洋航行任务中,官兵睡眠障碍发生比例较高;随着航行时间的延长,入睡时间延长,睡眠效率和睡眠质量下降,日间功能障碍程度加重.

abstractsObjective To investigate and analyze the sleep disorder at different time points among commissioned and enlisted shipboard navy personnel during prolonged single ship deployment at sea.Methods The Pittsburgh Sleep Quality Index (PSQI) questionnaires were issued to 150 commissioned and enlisted navy personnel at month 1,2,3 and 4 during deployment at sea for self-evaluation of sleep quality of the shipboard navy personnel.Results One hundred and two commissioned and enlisted navy personnel completed the questionnaire survey.The PSQI scores in the first,second,third and fourth months were 4.09 ± 2.23,5.87 ± 2.09,7.26 ± 3.32 and 7.71 ± 3.87 respectively.Statistical significance could be noted in the scores,when comparisons were made between months (P ＜ 0.01).With the scores ＞ 7 as the critical point of sleep disorder,the percentages of the people with sleep disorder at 4 different time points were respectively 29.4％ in the first month,34.3％ in the second month,47.1％ in the third month and 48.0％ in the fourth month,and statistical significance could be noted,when comparisons were made between groups (P ＜ 0.01).Statistical differences could be noticed in sleep quality,sleep latency,sleep efficiency and daytime dysfiunction,when comparisons were made between the months (P ＜ 0.01).There was no obvious correlation between PSQI scores and the age,educational background,position (officers or soldiers) and years of service (P ＞ 0.05).Conclusions During this prolonged single ship deployment at sea,the rate of sleep disorder occurred among navy personnel was relatively higher.With the extension of deployment at sea,sleep latency was prolonged,sleep efficiency and sleep quality were decreased and daytime dysfunction deteriorated.
