The effect of noise and vibration exposure on disturbed sleep has been investigated in the past. However, this study was carried out to investigate the relationship between workplace noise and vibration exposure with insomnia amongst representative Korean workers, both simultaneously and separately.
Our research analyzed an overall population of 30,837 workers aged 15 years or older using data derived from the 5th Korean Working Conditions Survey (KWCS) conducted in 2017. Chi-squared tests and logistic regression were performed to investigate baseline characteristics and to quantify the association between workplace exposure to noise and vibration with insomnia. Relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (S) were calculated to measure interactions between simultaneous noise and vibration exposure with insomnia.
The prevalence of those who reported insomnia was 18.3% of the general population. Among men and women, insomnia in those who were exposed to noise only was 13.9% and 18.3%, respectively, and in those who were exposed to vibration only, it was 23.9% in males and 26.4% in females. Insomnia in those who were exposed to both noise and vibration simultaneously was 20.5% and 41.2% in men and women, respectively. The odds ratio (OR) of insomnia due to noise exposure was 1.10 and 1.07 in men and women, respectively. OR of vibration exposure was 1.84 in men and 1.58 in women. For noise plus vibration exposure OR was 1.83 in men and 3.14 in female workers, where the synergistic effect of noise and vibration exposure could be seen. The association between the varying degree of simultaneous noise plus vibration exposure with insomnia showed a dose-response relationship. The interaction measures showed a synergistic effect of simultaneous exposure in women but not in men.
Our study revealed an association between occupational noise and vibration exposure and insomnia, both individually and simultaneously. Additional studies and research are required to further comprehend this relationship.
过去曾对噪声和振动暴露对睡眠障碍的影响进行过研究。然而，本研究旨在调查韩国代表性工人中工作场所噪声和振动暴露与失眠之间的关系，包括同时暴露和单独暴露的情况。
我们的研究分析了2017年进行的第五次韩国工作条件调查（KWCS）中15岁及以上的30837名工人的总体数据。进行卡方检验和逻辑回归以调查基线特征，并量化工作场所噪声和振动暴露与失眠之间的关联。计算交互作用的相对超额危险度（RERI）、归因比例（AP）和协同指数（S），以衡量噪声和振动同时暴露与失眠之间的交互作用。
报告失眠的人群患病率为总人口的18.3%。在男性和女性中，仅暴露于噪声的人群中失眠率分别为13.9%和18.3%，仅暴露于振动的人群中，男性为23.9%，女性为26.4%。同时暴露于噪声和振动的人群中，男性和女性的失眠率分别为20.5%和41.2%。男性因噪声暴露导致失眠的优势比（OR）分别为1.10和1.07。振动暴露的OR在男性中为1.84，在女性中为1.58。对于噪声加振动暴露，男性工人的OR为1.83，女性工人为3.14，可见噪声和振动暴露的协同效应。不同程度的噪声加振动同时暴露与失眠之间的关联呈现剂量反应关系。交互作用测量显示，同时暴露在女性中有协同效应，而在男性中则没有。
我们的研究揭示了职业噪声和振动暴露与失眠之间的关联，无论是单独暴露还是同时暴露。需要进一步的研究来进一步理解这种关系。
