Purpose : We investigated the influences of shift work---the imbalance of individual autonomic nervous function. the change of the adaptation process and the characters of the external factors about the diseord. Also we investigated the relation between the results of autonomic nervous system and subjective symptoms. considering the health practice of the worker. We also considered effective work schedules and lifestyle guidance based on this study.Subjects : We studied 124 men working at a steel pipe manufacturing plant.Results ＆ discussion :1. Measurement of heart rate variability and the automatic nervous functionSympathetic nerve system was superior between work-time while parasympathetic nerve system was superior between steep-time. Activity of sympathetic nervous system between sleep-time on the 2^<nd> night-work was significantly lower than that of the 3^<rd> day-work. Also the activity of sympathetic nervous system between sleep-time on the 4^<th> night-work elevated as high as … More day-work. We supposed there was an adaptation process in autonomic nervous function in shift workers.2. Questionnaire studyThere was no difference in subjective symptoms between work styles. Sleep improved in the 4^<th> night-work than in the 2^<nd> night-work. Also, shift workers were better in the mental and physical health than day-workers researched by General Health Questionnaire (GHQ). We considered that the factors, with may influence the GHQ score, are the custom to the shift-work and work environment during day and night-time. Day-worker had good health practice about their lifestyle shown by Health Practice Index (HPI) results. These was no difference between work styles shown by Work Stressor Check list (WSC) results.3. Retrospective study about the blood pressure of shift workerThere was no difference about Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) between work styles. We considered that these results might be a manifestation of healthy worker effect.4. Intervention studyThere was no difference about SBP and DBP between work styles. But subjective symptoms, sleep and health practice were improved significantly.Conclusion : We were able to classify the adaptation process about autonomic nervous systems in shift work and recovery from night work at the point of sleep. And we were able to improve in the subjective factors by our intervention. Less

目的：探讨轮班工作对个体自主神经功能的影响。适应过程的变化和疾病的外部因素的特点。并探讨了自主神经功能测定结果与主观症状的关系。考虑到工人的健康习惯。研究对象：本研究以一家钢管厂的124名男性员工为研究对象。心率变异性和自主神经功能的测量工作时间之间交感神经系统上级，而陡变时间之间副交感神经系统上级。夜间工作组睡眠时间之间的交感神经系统活性<nd>显著低于白天<rd>工作组。4、夜间工作的睡眠时间之间的交感神经系统活性升高<th>， ...更多信息 日工我们认为倒班工人的自主神经功能存在一个适应过程.问卷调查不同工作方式的患者主观症状无差异。睡眠改善在4^<th>夜间工作比2^<nd>夜间工作。一般健康问卷（GHQ）调查结果显示，倒班工人的身心健康状况优于白班工人。本研究认为，影响GHQ得分的因素有：轮班工作习惯和昼夜工作环境。健康实践指数（HPI）结果显示，日工对他们的生活方式有良好的健康实践。工作压力源检查表（WSC）结果显示，不同工作风格的学生在这些方面没有差异.倒班工人血压的回顾性研究不同工作方式之间的收缩压和舒张压无显著性差异。我们认为这些结果可能是健康工人效应的一种表现.干预研究不同工作方式之间SBP、DBP无差异。结论：我们可以从睡眠的角度对倒班和夜班后恢复的自主神经适应过程进行分类。通过我们的干预，我们能够改善主观因素。少
