Sleep disturbance is associated with negative effects to workers' health and productivity; hence, it is important to find which population of workers are associated with sleep disturbance. This study aimed to investigate the association between physical risk factors (vibration, noise, high, and low temperatures) and sleep disturbance in the Korean working population.
We analyzed data on 29,213 paid workers from the 5th Korean Working Conditions Survey. Individual and occupational characteristics, physical risk factors exposure, and sleep disturbance were collected using self-reported questionnaires. To assess the association between physical risk factors and sleep disturbance, the chi-square test and multivariable logistic regression models were conducted. All statistical analyses were performed in sex-based subgroups.
We observed that all physical risk factors are associated with sleep disturbance. The adjusted odds ratios (95% confidence interval [CI]) of severe exposure to vibration, noise, high and low temperature were 1.69 (CI:1.47-1.94), 2.52 (CI:2.17-2.92), 3.09 (CI:2.69-3.56), and 1.96 (CI:1.68-2.28) in male workers and 2.27 (CI:1.89-2.72), 3.52 (CI:2.92-4.24), 3.30 (CI:2.81-3.87), and 2.87 (CI:2.44-3.38) in female workers, respectively. The prevalence of sleep disturbance increased with increased exposure to physical risk factors, indicating a dose-response relationship.
Physical risk factors exposure in the workplace was associated with sleep disturbance of workers, indicating a dose-response relationship. Given the impact of sleep disturbance on workers' health and efficiency, it may be important to control exposure to physical risk factors in the working environment with regards to sleep conditions.
睡眠障碍与工人的健康和生产力下降有关；因此，找出哪些工人群体与睡眠障碍有关是很重要的。本研究旨在调查韩国劳动人群中物理危险因素（振动、噪声、高温和低温）与睡眠障碍之间的关系。
我们分析了来自第 5 次韩国工作条件调查的 29213 名有酬工人的数据。个体和职业特征、物理危险因素暴露和睡眠障碍通过自报问卷收集。为了评估物理危险因素与睡眠障碍之间的关系，进行了卡方检验和多变量逻辑回归模型分析。所有的统计分析都是按性别分组进行的。
我们发现所有的物理危险因素都与睡眠障碍有关。严重接触振动、噪声、高温和低温的男性工人的调整后比值比（95%置信区间[CI]）分别为 1.69（CI：1.47-1.94）、2.52（CI：2.17-2.92）、3.09（CI：2.69-3.56）和 1.96（CI：1.68-2.28），女性工人分别为 2.27（CI：1.89-2.72）、3.52（CI：2.92-4.24）、3.30（CI：2.81-3.87）和 2.87（CI：2.44-3.38）。随着物理危险因素暴露的增加，睡眠障碍的发生率也随之增加，表明存在剂量反应关系。
工作场所物理危险因素的暴露与工人的睡眠障碍有关，表明存在剂量反应关系。鉴于睡眠障碍对工人健康和效率的影响，控制工作环境中物理危险因素的暴露以改善睡眠条件可能很重要。
