“…We found that the prevalence of SWD among these workers was 62.8% in our sample, which is very high compared with the rates found by other studies using the same criteria for SWD [5,6,8]. The participants in the study conducted by Di Milia L et al [5] were drawn from the community and worked various types of shift, including some involving few nights, which may explain the low prevalence reported by that study.…”

“…The participants in the study conducted by Di Milia L et al [5] were drawn from the community and worked various types of shift, including some involving few nights, which may explain the low prevalence reported by that study. In contrast, the participants in a research conducted by Waage S et al [6] followed a slow rotation shift schedule. It is possible that rapidly rotating shift work tends to cause sleep disorders because of its association with a reduction in the total duration of sleep [17].…”

“…We used three questions to detect SWD according to the aforementioned ICSD-2 definition [6]: (1) Do you experience difficulties with sleeping or experience excessive sleepiness? (yes or no), (2) Is the sleep or sleepiness problem related to a work schedule that involves working when you would normally sleep?…”

“…The international classification of sleep disorders (ICSD-2) issued the following diagnostic criteria for SWD: 1) complaints of insomnia or excessive sleepiness that are temporally associated with a recurring work schedule that overlaps with the usual time for sleep, 2) symptoms must be associated with the shiftwork schedule over the course of at least 1 month, 3) circadian and sleep-time misalignment, as demonstrated by sleep logs or actigraphical monitoring for 7 days or more and 4) the sleep disturbance cannot be explained by another sleep disorder, a medical disorder, neurological disorder, mental disorder, or medication, or use of other substances. Several studies of the prevalence of SWD in shift workers have been conducted [4][5][6][7][8]. Drake CL et al [4] and Di Milia L et al [5] reported that the prevalence of SWD was 26.1% and 32.1%, respectively, in mixed samples of different types of shift work schedules.…”

Waage S et al [6] found that the prevalence of SWD was 23.3% in shift workers following a slow rotating shift-work schedule that involved repeatedly working in the same factory during either the day or the night every 1 or 2 weeks. In Japan, the prevalence of SWD among nurses working in shift was 24.4% [7].…”

: The aim of this study was to examine the relationship between shift-work disorder (SWD) and environmental and somatic factors related to falling asleep among rapidly rotating shift workers in a manufacturing industry. A total of 556 male workers were recruited to complete a self-administered questionnaire regarding age, shift work experience, lifestyle, and family structure; the Epworth sleepiness scale (ESS); the Pittsburgh sleep quality index (PSQI); and the Horne and Ostberg questionnaire, a questionnaire for environmental and somatic factors related to falling asleep. We classified workers according to having SWD or not, and compared workers with SWD with those without this disorder in terms of all items covered in the aforementioned questionnaires. A total of 208 workers (62.8%) working rapidly rotating shifts were diagnosed with SWD. The ESS and PSQI scores and scores for environmental and somatic factors were significantly higher in workers with SWD than in those without this disorder. The ESS scores and scores for environmental and somatic factors were also associated with SWD in the logistic regression analyses. We suggest that susceptibility to SWD in the manufacturing industry may be associated with environmental and somatic factors related to falling asleep.

“… and God divided the light from the darkness, and God called the light day , and the darkness He called night . And the evening and the morning were the first day” (Genesis 1:4–5, King James Version). So from the beginning, day/night periodicity has been an important environmental influence on life on earth. For diurnal species, like human beings, the sunlight portion of the day is the time for activity and the dark, nighttime for sleeping. Although we are under the influence of environmental rhythms, such as the daylight–night cycle, we are also under the physiological influence of our own internal biological clock. Normally synchronization of biological rhythms with each other and with environmental rhythms (external time cues) maximizes our waking and sleeping performance and promotes overall well‐being. Night work is opposed to the innate drive to sleep at night and work during the daytime and results in an unnatural mismatch of environmental and internal time cues. Shiftworkers are exposed to disruptive effects of schedule‐related time shifts on the normal synchronization of individual biological rhythms with each other as well as with the external time cues. This chapter reviews basic chronobiological principles as they relate to shiftworker safety and health. Studies dealing with the effects of time shifts on sleep, alertness, and performance rhythms are discussed. Research exploring the consequences of shiftwork on physical and mental health is reviewed. Countermeasures for minimizing adverse health and safety effects of sleep deprivation and biological rhythm disruption are presented. Industrial hygiene considerations related to control of worker exposure to potential toxins during extended and rotating shifts are considered. Finally, international and U.S. regulatory policy regarding shiftwork scheduling and special medical provisions for shiftworkers are reviewed.

Shift Work Disorder Among Oil Rig Workers in the North Sea

Abstract: The prevalence of SWD was relatively high among these shift workers. Individuals with SWD reported poorer sleep quality and more subjective health complaints in the non-work period than shift workers not having SWD.
