This study examined whether cognitive symptoms and health-related quality of life can be affected by welding fume exposure.
Participants consisted of welders (n = 40) and welder assistants (n = 25) from welding units as the exposed group, and office workers (n = 44) as the non-exposed group. All participants were studied using ambient air monitoring and two types of questionnaires: the Cognitive Failures Questionnaire (CFQ) and the 36-item Short Form Health Survey (SF-36).
Welders and welder assistants were exposed to higher concentrations of all airborne metals than office employees, except for aluminum and chromium (p < 0.05). Mean (95% confidence interval) CFQ score was higher in welders (26.42 (12.74)) compared with welder assistants (22.68 (14.37)) and the non-exposed group (21.38 (8.75)), although these differences were not statistically significant. Mean total score of the SF-36 significantly differed among the three groups (p < 0.05) and welders had the lowest score (M (SD) = 54.84 (17.88)). The relationships between total CFQ score and the measured concentration of nickel at peak work rate was significant for welders.
Cognitive symptoms and health-related quality of life were not related to the measures of welding fume exposure and further research should be performed to find other influencing factors.
本研究探讨了焊接烟尘暴露是否会影响认知症状和健康相关生活质量。
参与者包括来自焊接单位的焊工（n = 40）和焊接助手（n = 25）作为暴露组，以及办公室职员（n = 44）作为非暴露组。所有参与者均接受环境空气监测以及两种问卷调查：认知失误问卷（CFQ）和36项简明健康调查（SF - 36）。
除铝和铬外，焊工和焊接助手接触的所有空气中金属浓度均高于办公室职员（p < 0.05）。焊工的平均（95%置信区间）CFQ得分（26.42（12.74））高于焊接助手（22.68（14.37））和非暴露组（21.38（8.75）），尽管这些差异无统计学意义。SF - 36的平均总分在三组之间有显著差异（p < 0.05），焊工得分最低（M（SD）= 54.84（17.88））。焊工在工作峰值时CFQ总分与镍的测量浓度之间的关系显著。
认知症状和健康相关生活质量与焊接烟尘暴露指标无关，应进一步开展研究以寻找其他影响因素。
