全身振动对卡车司机消化系统危害调查研究

Investigation an the Impairment of whole Body Vibration on the digestive systems of Truck Drivers

文章对８６名卡车司机接触全身振动对消化系统的影响进行了调查研究，发现当卡车ａｚ轴、ａｘ轴振动加速度值与世界标准化组织《全身振动评价标准》（ＩＳＯ—２６３１）相比有７３．５％和１６．６％超过ＩＳＯ—２６３１—１９７８年“疲劳——减效界限”；１１．７％和３．３％超过“暴露极限”标准时，卡车司机胃炎、胃及十二指肠溃汤的患病率明显高于对照组，差别有显著意义（Ｐ＜０．０５）。

The author investigated the impairment of digestive systems in 86 whole body vibration exposed truck drivers.Compared with “evaluation of human exposure to whole body vibration”(ISO26311978)when the vibration acceleration in Az direction and Ax direction exceeded the fatiguedecreased proficiency boundary by 75.5% and 16.6%,exceeded the exposure limit by 11.7% and 3.3% the prevalence rate of gastritis and gastric duodenal ulcer was higher than the control group statistically,there was significant difference between two groups,(P<0.05).
