The results of a study on 68 VDT operators are hereby presented. Various biochemical indexes are evaluated as markers of stress. In particular, urinary catecholamines and their metabolites (E, NE, DA, HVA, VMA), ACTH, cortisol, NEFA and fructosamine have been tested by the Authors. Each assay has been performed both in basal conditions, and after the completion of subjects workshift, taking into account the normal hormonal biorhythms. The data which emerged have been analyzed by statistical method ("Student t" with coupled data). Each subject data was confronted before and after workshift. The number of hours of VDT exposure and the different types of duties have been considered and evaluated. The results show that, although the data are all included within the normal range, some of the tested parameters after workshift are significantly higher, compared with the same parameters referring to the basal condition. In particular, Epinephrine and Norepinephrine seem to be the most effective markers of stress. Analogous studies will be pursued in the future by the Authors on a larger number of VDT operators.
在此呈现一项针对68名VDT操作人员的研究结果。评估了各种生化指标作为压力的标志物。特别地，作者检测了尿儿茶酚胺及其代谢产物（E、NE、DA、HVA、VMA）、促肾上腺皮质激素、皮质醇、非酯化脂肪酸和果糖胺。每项检测均在基础条件下以及受试者轮班结束后进行，同时考虑到正常的激素生物节律。所出现的数据已通过统计方法（配对数据的“学生t检验”）进行分析。对每个受试者轮班前和轮班后的数据进行了对比。考虑并评估了VDT暴露的小时数和不同类型的工作任务。结果表明，尽管所有数据均在正常范围内，但与基础条件下的相同参数相比，轮班后的一些检测参数显著更高。特别是，肾上腺素和去甲肾上腺素似乎是最有效的压力标志物。作者未来将对更多的VDT操作人员进行类似研究。
