BACKGROUND AND PURPOSE
Traffic noise <60 dB(A) has been associated with an increased risk of stroke. We investigated this relationship for 80 to 86 dB(A) occupational noise.
METHODS
We followed 116,568 industrial and 47,679 financial workers by linkage to Danish registries 2001 through 2007. Full-shift noise levels were estimated from subsets of workers at baseline and end of follow-up.
RESULTS
We identified 981 stroke patients and observed a 27% increased confounder-adjusted risk of stroke for industrial compared with financial workers. However, longer duration or higher noise level within the industrial workers were unrelated to the risk of stroke.
CONCLUSIONS
Our study did not support an association between occupational noise exposure and stroke, and the higher risk among industrial workers may reflect lifestyle differences.
背景与目的
交通噪声<60 分贝（A）与中风风险增加有关。我们研究了 80 至 86 分贝（A）职业噪声的这种关系。
方法
我们通过与丹麦登记处的联系，在 2001 年至 2007 年期间对 116568 名工业工人和 47679 名金融工人进行了随访。根据基线和随访结束时的工人子集，估算了全班噪声水平。
结果
我们确定了 981 例中风患者，与金融工人相比，工业工人中风的混杂因素调整风险增加了 27%。然而，在工业工人中，暴露时间更长或噪声水平更高与中风风险无关。
结论
我们的研究不支持职业噪声暴露与中风之间的关联，而工业工人的风险较高可能反映了生活方式的差异。
