“…Regarding the subgroup analysis of occupational variables and noise and vibration exposure in individuals with insomnia, men and women who did not wear PPE when required and were exposed to vibration exposure only or both noise and vibration exposure, therefore eliminating a form of protection against the two exposures, had a significantly higher risk of insomnia supporting the findings of a prior study [9]. The implications of not wearing specialized PPE such as earplugs for noise exposure or anti-vibration gloves for vibration exposure can be severe; therefore, the World Health Organization (WHO) released guidelines regarding PPE use to lessen these harmful effects [40].…”

“…The rationale behind investigating the effect of both noise and vibration with insomnia is that, for instance, when handling large equipment or driving large vehicles, workers are often exposed to noise and vibration simultaneously in their work environments. A prior study carried out in Korea showed that combined noise and vibration exposure had a greater effect on the increased total of nervous system-related disorders, which included headache/eyestrain, fatigue, and sleep disturbance/insomnia [9]. Therefore, there is a need to investigate the combined effect of noise and vibration.…”

“…On the other hand, our study's main strong point is that, to the extent of our knowledge, this is the first study in South Korea and one of the few studies worldwide to focus on the simultaneous exposure of noise and vibration effects on insomnia. Other studies have previously investigated the effect of noise and vibration exposure on a variety of mental health problems [9,45]. However, those exposures were investigated individually, not simultaneously.…”

“…Exposure to environmental stressors such as noise and vibration and their detrimental effects on health and diseases have been explored frequently in other studies. Some of these effects include, but are not limited to, physiological conditions such as hearing loss [1], cardiac and vascular problems [2,3], and elevated blood pressure [4,5], as well as nervous system-related disorders such as stress, annoyance [6], headache/eye strain [7], fatigue [8], and perhaps the most prominent nervous system issue-insomnia/sleep disturbance [9][10][11].…”

Background: 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. Methods: 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. Results: 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. Conclusion: 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.

“…Additionally, although vibration exposure could be divided into whole-body vibration, motion sickness, and hand-transmitted vibration [35], the survey did not include this breakdown of vibration types, potentially introducing error. Previous studies have reported that workers who do not wear personal protection devices are more easily exposed to hazardous factors such as noise or vibration [36], but this study could not adjust for the use of personal protection devices. Additionally, we could not adjust for variables such as job stress or psychosocial work environment, which have also been suggested to ergonomic risk factors [37–39].…”

BackgroundIt is well known that ergonomic risk factors and back pain are related. However, few studies have examined the relationship between simultaneous exposure to these risk factors and back pain in a Korean population. We aimed to investigate the relationship between simultaneous exposure to ergonomic risk factors and work-related lower back pain (LBP) based on the fourth Korean Working Conditions Survey (KWCS).MethodThe fourth KWCS (2014) was used for this study. Chi-square tests and logistic regression were used to assess relationship between 5 ergonomic risk factors and work-related LBP. We also analyzed the relationship between simultaneous exposure to 2 risk factors and work-related LBP.ResultsAll 5 ergonomic risk factors (fatigue-inducing and painful posture; lifting or moving people; dragging, pushing, or moving heavy objects; standing posture; and repetitive hand or arm movements) were significantly correlated with work-related LBP in the severe exposure group (adjusted odd ratios [aOR] 5.09, 95% confidence interval [CI] 4.46–5.83; aOR 1.98, 95% CI 1.62–2.42; aOR 2.09, 95% CI 1.82–2.40; aOR 1.79, 95% CI 1.60–2.01; aOR 2.04, 95% CI 1.82–2.30, respectively). When exposed to 2 risk factors simultaneously, the relationship between exposure and work-related LBP was not greater than exposure to only 1 risk factor in our study (usually exposed to ‘fatigue-inducing or painful posture’ aOR 2.17, 95% CI 2.02–2.34; high exposure to both ‘fatigue-inducing or painful posture’ and ‘dragging, pushing, or moving heavy objects’ aOR 2.00, 95% CI 1.82–2.20).ConclusionsThere was a strong relationship between severe exposure to each ergonomic risk factor and work-related LBP. However, when exposed to 2 ergonomic risk factors simultaneously, the relationship between exposure and work-related LBP was not stronger than when exposed to only 1 risk factor in our study.
