目的研究职业对听力的影响，以及在调整噪声暴露、教育程度、收入和其他危险因素后是否仍然存在。方法对挪威普通成年人群样本（N= 49948）进行听力测量和暴露问卷调查。有关职业、教育和收入的资料来自人口普查登记册。结果职业对听力损失有显著影响。除了年龄导致的听力损失（10-19%）外，职业解释了45岁男性听力损失方差的2-3%。职业解释= 45年。在控制了休闲噪音、耳部感染和头部损伤后，职业的影响没有改变，在控制了教育和收入后，职业的影响略有降低。男性听力阈值最高的人群有：木工；矿工;敷设和电缆接头；建筑木匠和工人；海员;还有车间机械师。结论职业与听力损失存在中度相关性。对职业性听力损失的无偏估计可能有助于识别需要干预的高危职业，并识别听力损失个体。
Objectives We studied the effect of occupation on hearing and if it remained after adjustment for noise exposure, education, income, and other risk factors.Methods Audiometry and a questionnaire concerning exposure was administered to a general adult population sample in Norway (N=49 948). Information on occupation, education, and income was obtained from population census registers.Results Occupation had marked effects on hearing loss. Occupation explained 2-3% of the variance in hearing loss among men >= 45 years in addition to the hearing loss due to age (10-19%). Occupation explained = 45 years. Controlling for leisure-time noise, ear infections, and head injuries did not change the effect of occupation, which was slightly reduced after controlling for education and income. The most elevated hearing thresholds in men were observed among: wood workers; miners; linemen and cable jointers; construction carpenters and workers; seamen; and workshop mechanics.Conclusions There was a moderate association between occupation and hearing loss. Unbiased estimates of occupational hearing loss may help identify high-risk occupations, for which interventions are needed, and identify individuals with hearing loss.
