振动与噪声对人体听觉系统、神经系统、心血管系统的危害研究已较清楚,但对消化系统的危害还有待进一步研究。本文通过对接触振动与噪声较强的拖拉机司机消化系统专项检查,并以小型轿车司机作对照,探讨了这一问题,报告如下。1 调查对象与方法1.1 调查对象 330名男性拖拉机司机,年龄20.5～51.7岁,平均30.2岁。工龄1～24年,平均7.1年。120名小型轿车司机,年龄18～55.5岁,平均27.4岁。工龄1～27年,平均9.5年。1.2 方法 在机动车驾驶员年度体检时,对调查组和对照组进行消化系统专项复检。项目包括问诊(职业史、胃肠道症状)、内 Vibration and noise on the human auditory system, nervous system, cardiovascular system hazards have been more clear, but the harm to the digestive system remains to be further studied. In this paper, the contact vibration and noise of the tractor driver digestive system special inspection, and a small car driver as a control, discussed the issue, the report is as follows.
