目的调查长时间海上航行人员睡眠状况,以探讨可能的影响因素。方法随机抽取参加执行远海航行任务人员120人,通过匹茨堡睡眠质量指数(PSQI)调查表,自我评价睡眠状况及环境改变对睡眠的影响和睡眠调整情况。结果被调查者平均PSQI积分为(6.79±0.28);39例PSQI积分≥8分(32.5%),主要表现为平均睡眠时间减少、睡眠效率降低、入睡时间延长;日间出现困倦感达52%。生活环境和作息习惯的改变及时间差调整是影响睡眠状态的主要因素。结论长时间海上航行人员存在睡眠障碍且发生比例较高,睡眠障碍一般持续1～3周,经自我调整可以改善或恢复。
Objective To investigate the long-term sleep conditions of the sea-going crew in order to explore the possible influencing factors. Methods A total of 120 participants participated in the task of far sea navigation were randomly selected. The PSQI questionnaire was used to evaluate the impact of sleep and environmental changes on sleep and sleep adjustment. Results The average PSQI score of the respondents was (6.79 ± 0.28), and the score of PSQI was ≥8 (32.5%) in 39 patients. The main symptoms were as follows: the average sleep time decreased, the sleep efficiency decreased and the sleep time prolonged; the sleepiness reached 52% . Changes in living environment and habits and habits and time adjustment is the main factor affecting sleep status. Conclusion For a long time there is a high incidence of sleep disorders in the sea-going crew. Sleep disorders usually last 1-3 weeks, and self-adjustment can improve or recover the sleep disorders.
