Introduction. Work of locomotive crew members (engine drivers and engine driver assistants) in railway transport is associated with exposure to complex of occupational hazards including psychoemotional stress and shiftwork (with night shifts) along with noise and vibration.Objective. To study influence of shift work (with irregular alternation of day and night shifts) on biorhythms disturbances in locomotive crew workers.Materials and methods. Polls, simulators of occupational activities with training complex «Cabin of engine driver EP1M», daily monitoring of blood pressure, statistic data processing by SPSS–20 software.Results. Findings are that 953 locomotive crew workers (94%) experienced sensations of temporary disorientation, slight dizziness, sleepiness, interpreted as monotony and sensor deprivation. 61% of the examinees demonstrated frustration signs, in 30% of the cases there were certain manifestations of mental ill-being — irritability, fatigue, weariness, absent-mindedness, anxiety; 27.2% of the testees experiences various sleep disorders; 13.8% of the workers complained of «light sleep», 2% of those — restless sleep, 0.6% — sleeplessness. In occupationally related biorhythms disturbance, the body undergoes occupational adaptation, with partial transformation for atypical schedule of sleep and wakefulness.Results. To preserve health, efforts should be aimed at adaptation to shifted occupational activities with safe adaptogenic medications, low-caloric diet for individuals working at irregular shifts, create conditions for adequate physical activity of the workers between shifts. Necessities also are individual norms for blood pressure parameters in engine drivers with night shiftwork, specification of antihypertensive treatment for patients with irregular shifted work.

Abstract Purpose We aimed to cross-sectionally investigate how work and sleep conditions could be associated with excessive fatigue symptoms as an early sign of Karoshi (overwork-related cerebrovascular and cardiovascular diseases; CCVDs). Methods We distributed a questionnaire regarding work, sleep, and excessive fatigue symptoms to 5410 truck drivers, as the riskiest occupation for overwork-related CCVDs, and collected 1992 total samples (response rate: 36.8%). The research team collected 1564 investigation reports required for compensation for Karoshi. Of them, 190 reports listed the prodromes of Karoshi, which were used to develop the new excessive fatigue symptoms inventory. Results One-way analyses of variance showed that the excessive fatigue symptoms differed significantly by monthly overtime hours (p < 0.001), daily working time (p < 0.001), work schedule (p = 0.025), waiting time on-site (p = 0.049), number of night shifts (p = 0.011), and sleep duration on workdays (p < 0.001). Multivariate mixed-model regression analyses revealed shorter sleep duration as the most effective parameter for predicting excessive fatigue symptoms. Multiple logistic regression analysis confirmed that the occurrences of CCVDs were significantly higher in the middle [adjusted ORs = 3.56 (1.28–9.94)] and high-score groups [3.55 (1.24–10.21)] than in the low-score group. Conclusion The findings suggested that shorter sleep duration was associated more closely with a marked increase in fatigue, as compared with the other work and sleep factors. Hence, ensuring sleep opportunities could be targeted for reducing the potential risks of Karoshi among truck drivers.

The study aimed to explore chronotype-specific effects of two versus four consecutive morning or night shifts on sleep-wake behavior. Sleep debt and social jetlag (a behavioral proxy of circadian misalignment) were estimated from sleep diary data collected for 5 weeks in a within-subject field study of 30 rotating night shift workers (29.9 ± 7.3 years, 60% female). Mixed models were used to examine whether effects of shift sequence length on sleep are dependent on chronotype, testing the interaction between sequence length (two vs. four) and chronotype (determined from sleep diaries). Analyses of two versus four morning shifts showed no significant interaction effects with chronotype. In contrast, increasing the number of night shifts from two to four increased sleep debt in early chronotypes, but decreased sleep debt in late types, with no change in intermediate ones. In early types, the higher sleep debt was due to accumulated sleep loss over four night shifts. In late types, sleep duration did not increase over the course of four night shifts, so that adaptation is unlikely to explain the observed lower sleep debt. Late types instead had increased sleep debt after two night shifts, which was carried over from two preceding morning shifts in this schedule. Including naps did not change the findings. Social jetlag was unaffected by the number of consecutive night shifts. Our results suggest that consecutive night shifts should be limited in early types. For other chronotypes, working four night shifts might be a beneficial alternative to working two morning and two night shifts. Studies should record shift sequences in rotating schedules.

Objective: This study aimed to examine the psychological work environments and associated factors among clinical nurses in a provincial tertiary hospital in the North of Vietnam in 2020. Methods: A cross-sectional survey was conducted among all nurses of 22 clinical wards who directly provided care to patients. 261/318 eligible nurses returned the self-reported survey questionnaires that consisted of the Vietnamese version of the Job Content Questionnaire 22 items and originally developed questions on personal characteristics and work conditions. Descriptive analysis, t-test, ANOVA, and multivariate linear regressions were applied to describe the current job demand, job control, and related factors at the significant level p less than 0.05. Results: The response rate of the current study was 82.1%. Nurses reported moderate job demand (29.39±3.64) and job control (66.86±5.79). Increased job control was significantly associated with more frequency of receiving support from superiors (p<0.001), a self-perceived opportunity of promotion (p = 0.011), and more night shifts per week (p=0.004). Less support from co-workers and more night shifts were associated with a higher job demand score among study participants (p = 0.041 and 0.002, respectively). Conclusions: Several nurses in the provincial hospital work in unfavorable work environments with high job demand and low job control, which could adversely affect nurses’ well-being. It is essential to promote social support at work to improve the psychological working conditions and performance of study participants.
