高铁夜间作业人员睡眠状况分析

Analysis of Sleep Status of High-speed Rail Workers at Night

目的为了解高铁维修车间职工的睡眠状况,研究长期频繁的日夜倒班工作制对睡眠自然周期循环的影响,分析睡眠质量的影响因素,为进一步改进工作机制提供依据。方法选择高铁维修车间接触网工、桥隧工、线路工、信号工四个工种,采用调查问卷,具体内容包括基本信息和匹兹堡睡眠质量指数(PSQI)问卷,采用SPSS 17.0统计软件进行统计学分析。结果睡眠质量较差和很差者占63.2%,入睡时间≥2 h者占70.2%,睡眠时间≤7 h者占70.1%,睡眠质量与年龄、工龄、工作班制、工种、患有慢性病、吸烟、是否吃早餐等因素有关。结论高血压、糖尿病等慢性病与职业压力高度相关,不吃早餐,空腹时间长会严重影响睡眠质量。

Objective To understand the sleep status of workers in high-speed rail maintenance workshops,to study the effect of long-term frequent day and night shift work on the natural cycle of sleep,to analyze the influencing factors of sleep quality,and to provide a basis for further improvement of the working mechanism.Methods Four types of workers,including catenary worker,bridge and tunnel worker,line worker and signal worker were selected in the high-speed rail maintenance workshop,and questionnaires were used.The specific contents included basic information and Pittsburgh Sleep Quality Index(PSQI)questionnaire.SPSS 17.0 statistical software was used for statistical analysis.Results 63.2%had poor or very poor sleep quality,70.2%had a sleep time of 2 hours or more,and 70.1%had a sleep time of less than 7 hours.There are chronic diseases,smoking,whether to eat breakfast and other factors.Conclusion Chronic diseases such as hypertension and diabetes are highly correlated with occupational stress,skipping breakfast and long fasting time will seriously affect sleep quality.
