应用世界卫生组织推荐的神经行为核心测试组合 (WHO—NCTB)的方法对 199名噪声作业工人的神经行为功能进行测试 ,同时选择 52名在年龄、工龄、文化程度、经济状况、性别等相似的非噪声作业者为对照组。测试结果表明 ,随着噪声暴露水平的增强 ,作业工人各项负性情绪因子得分增多 ,正性情绪因子得分则减少 ,神经行为不良效应明显增多 ,其中超标暴露组紧张—焦虑、抑郁—沮丧、疲惫—惰性、慌乱—困惑、数字译码、数字广度、目标追踪、视觉保留、简单反应时得分与对照组比较差异显著 ;而且不同性别间比较 ,部分测试项目得分存在显著性差异。NCTB可以用作噪声危害早期临床前损害的检测方法。
The neurobehavioral functions of 199 noisy workers were tested using WHO-NCTB method. At the same time, 52 neurobehavioral workers with similar age, seniority, education, economic status and gender Non-noise workers as a control group. The test results show that with the increase of noise exposure, the negative scores of occupational workers increased, the scores of positive emotional factors decreased, and the neurological behavioral adverse effects increased significantly. Among them, the stress of excessive exposure group-anxiety, depression-depression, Fatigue, inertness, confusion, confusion, digital decoding, digital breadth, target tracking, visual retention, and simple response scores were significantly different from the control group; and scores of some test items were significantly different among different sexes. NCTB can be used as a method of detecting noise damage to early preclinical lesions.
