“…Our findings suggest that more than noise exposure, exposure to vibration had a prominent effect on insomnia. In addition, the prevalence of insomnia was higher in females than in males, which is consistent with previous findings that women are more vulnerable to mental health problems than men [25,26]. However, with the exception of simultaneous noise and vibration exposure, the OR of insomnia was higher in males than females.…”

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.

“…Insomnia is defined as a sleep dissatisfaction, either qualitatively or quantitatively [ 11 , 12 ]. It is the most common sleep disorder, occurring in 6–18% of the general population [ 13 ].…”

“…Insomnia is common in elderly adults [ 7 ] in particular, with an overall prevalence of 30–48% [ 14 , 15 ]. Insomnia symptoms, such as difficulty in initiating sleep, difficulty in maintaining sleep due to frequent awakening, or problems returning to sleep after awakening, and early-morning awakening with an inability to return to sleep [ 11 ], result in lesser sleep time and poorer sleep quality [ 12 ]. These insomnia symptoms may also be associated with mental disorders such as depression, anxiety [ 11 , 12 ], and cognitive function [ 11 , 16 ].…”

“…The previously reported significant factors related to insomnia include gender, age, socioeconomic status, and psychiatric comorbidities [ 15 ]. The number of menopausal elderly women suffering from sleep disturbances or insomnia is higher, compared to the number of elderly men of the same age, due to estrogen hormone deficiency [ 12 ]. Physical activity (PA) can reduce insomnia symptoms and enhance sleep quality [ 17 , 18 ]; however, menopausal elderly women have muscle weakness, which may lead to reduced PA [ 19 , 20 ].…”

This study investigates the gait characteristics of elderly women, aged more than 65 years, with subthreshold insomnia stage at various walking speeds. A total of 392 participants (insomnia: 202 and controls: 190) wearing shoe-type inertial measurement units completed walking tests on a treadmill for a duration of 1 min at slower, preferred, and faster speeds. The insomnia group indicated lower pace parameters (range of Cohen’s d: 0.283–0.499) and the single support phase (Cohen’s d: 0.237), greater gait variability (range of Cohen’s d: 0.217–0.506), and bilateral coordination (range of Cohen’s d: 0.254–0.319), compared with their age-matched controls; the coefficient of variance (CV) of the stance phase at the faster speed condition was a crucial variable for distinguishing between insomnia and control groups. In addition, the insomnia group demonstrated insufficient gait adaptation at the slower and preferred speeds, as indicated by the CVs of the stride length, stride time, and step time. In particular, participants with worsened insomnia symptoms or sleep problems showed that these worse gait patterns may increase the potential risk of falling in elderly women. Thus, elderly women with subthreshold insomnia stage need to improve their sleep quality to enhance their physical functions.

Objectives: We aimed to compare the quality of sleep, tongue diagnosis, oral microbiology differences in insomnia of Liver qi stagnation (LQS) and Non-Liver qi stagnation (NLQS). Methods: 56 patients were classified as LQS or NLSQ type insomnia through the insomnia differentiation questionnaire. The depression scores between the groups were compared through beck depression inventory (BDI), and the sleep quality was compared through Pittsburgh sleep quality index (PSQI) and Insomnia Severity Index (ISI). We analyzed the sleep efficiency, total sleep time, total awake frequency, total and average awake time through actigraph. For the tongue diagnosis, the distribution of tongue coating in six areas were measured through Winkel tongue coating index (WTCI). Linear discriminant analysis was performed to observe the differences in composition of microbial strains between the groups. Results: The scores of BDI, ISI and PSQI were significantly higher in LQS group. The total sleep time in LQS group was significantly less than that of NLQS group. Among the areas of tongue, according to the WTCI, the amount of tongue coating in zones A and C was significantly small. In oral microbial analysis, there was no significant difference between the groups at the phylum level. At the genus level, Prevotella, Veillonella, and Streptococcus were predominant in LQS group, whereas Prevotella, Neisseria, and Streptococcus in NLQS group. Conclusions: It was meaningful that insomnia was more likely in LQS group than in NLQS group, and the composition of oral microorganisms was significantly different, which could lead to the diseases caused by stress.
