The aim of this study was to determine the relationship between vibration and noise exposure in the workplace and certain nervous system related symptoms (NSRS) among Korean workers.
Using data from the fourth Korean Working Conditions Survey, we investigated the influence of vibration and noise with three categories; none, mild, and severe, on sleep disturbance, overall fatigue, and headache/eye strain using logistic regression analysis with stratification by personal protective equipment (PPE) wearing status.
Severe noise/vibration exposure was associated in a dose-response fashion with NSRS; the odds ratios (ORs) for sleep disturbance, headache/eyestrain, and overall fatigue were 1.48/1.06, 1.46/1.26, and 1.56/1.28 for severe and mild noise/vibration exposure, respectively, compared with no exposure. Workers who did not wear PPEs were the most affected.
Occupational exposures to vibration and noise are associated with NSRS. Additional longitudinal studies and tightened education and safety measures are warranted.
本研究旨在确定韩国工人工作场所的振动和噪声暴露与某些神经系统相关症状（NSRS）之间的关系。
利用第四次韩国工作条件调查的数据，我们通过个人防护设备（PPE）佩戴状况分层，使用逻辑回归分析，研究了无、轻度和重度三类振动和噪声对睡眠障碍、全身疲劳以及头痛/眼疲劳的影响。
严重的噪声/振动暴露与NSRS呈剂量反应关系；与无暴露相比，严重和轻度噪声/振动暴露导致睡眠障碍、头痛/眼疲劳和全身疲劳的优势比（OR）分别为1.48/1.06、1.46/1.26和1.56/1.28。未佩戴PPE的工人受影响最大。
职业性接触振动和噪声与NSRS有关。有必要进行更多的纵向研究，并加强教育和安全措施。
