目的用因子分析评价钒化合物损害神经行为功能的效应特征。方法采用WHO推荐的神经行为测试组合(NCTB)测试钒接触人群(193人)和对照人群(273人)的神经行为功能。结果①提取了7个公因子,分别是消极情绪因子、注意力因子、短期视觉记忆因子、运动协调因子、运动速度和准确性因子、短期听觉记忆因子、积极情绪因子。②接钒组的运动协调、运动速度和准确性、短期听觉记忆、积极情绪低于对照组,消极情绪和短期视觉记忆高于对照组,差异均有统计学意义(P<0.05);两组注意力没有差异。结论钒化合物可增强接钒工人消极情绪和短期听觉记忆力,降低积极情绪、协调能力、短期视觉记忆力、运动速度及稳定性。
Objective To evaluate the effect of vanadium compounds on neurobehavioral function by factor analysis. Methods The neurobehavioral function of the Vanadium exposure group (193 persons) and the control group (273 persons) were tested using the Neurobehavioral Testing Combinations (NCTB) recommended by the WHO. Results ① Seven common factors were extracted, including negative emotion factor, attention factor, short-term visual memory factor, motor coordination factor, motor speed and accuracy factor, short-term auditory memory factor and positive emotion factor. (2) There was significant difference in motor coordination, speed and accuracy, short-term auditory memory and positive emotion in control group and negative emotion and short-term visual memory in control group (P <0.05) No difference in attention. Conclusion Vanadium compounds can enhance passive emotion and short-term auditory memory in vanadium-receiving workers, and reduce positive emotions, coordination ability, short-term visual memory, movement speed and stability.
