- Objectives: The objective of this study was to investigate the validity of the effort-reward imbalance (ERI) model in relation to disturbed sleep and fatigue. Methods: The study population derived from a subset of the WOLF (WOrk, Lipids, Fibrinogen) cohort study of cardiovascular risk in a working population who replied to the ERI-questionnaire comprising 789 men and 214 women. Cox regression analysis was used to calculate the prevalence ratio (PR) for sleep disorders and fatigue in relation to the components of ERI. Results: As sleep disturbances and fatigue, based on literature, were defined to be represented by the uppermost quintile, 14% of the men and 23% of the women were affected by sleep disturbances while 14 and 26%, respectively, were affected by fatigue. Higher levels of exposure for the ERI components were associated with increased prevalence of sleep disturbances and fatigue. For men, the strongest association was seen between high overcommitment and fatigue (PR 5.77, 95% confidence interval 2.89-11.5). For women, high effort and sleep disturbances (PR 4.04, CI 1.53-10.7), high effort/reward ratio and sleep disturbances (PR 4.13, CI 1.62-10.5), and between low reward and fatigue (PR 4.36, CI 1.79-10.6) yielded the most obvious associations. Conclusions: The present study adds sleep disturbances and fatigue to the list of adverse consequences of effort-reward imbalance.

Increased risk of ischemic heart disease in shift workers
- 1986
-
Ingår i: Lancet. - 0140-6736. ; 2:8498, s. 89-92
-
Tidskriftsartikel (refereegranskat)abstract
- 504 papermill workers were followed up for 15 years and the incidence of ischaemic heart disease (IHD) in shift workers was compared with that in day workers. The relative risk (RR) of IHD rose with increasing duration of reported exposure to shift work. A significant risk of IHD was associated with an exposure of 11 - 15 years (RR = 2.2, p less than 0.04) and of 16 to 20 years (RR = 2.8, p less than 0.03. The association was independent of age and smoking history. The RR of IHD fell sharply after 20 years of shift work. This was ascribed to the pronounced positive selection that had taken place in this group.

Prevalence of risk factors for coronary artery disease among day and shift workers
- 1988
-
Ingår i: Scandinavian journal of work, environment & health. - 0355-3140. ; 14:5, s. 317-321
-
Tidskriftsartikel (refereegranskat)abstract
- Several recent studies have indicated that shift work is associated with increased risk of coronary artery disease. In this cross-sectional study 361 shift workers were examined with respect to some major risk factors for coronary artery disease; 240 day workers constituted the reference group. A higher proportion of shift workers smoked (54 versus 39%). Shift workers also had significantly higher levels of serum triglycerides (1.61 versus 1.43 mmol/l). Body mass index and the blood pressure and total cholesterol levels did not differ between the groups. Multiple regression analyses demonstrated that shift work was significantly related to serum triglyceride levels also when age, smoking, body mass index, and other variables were controlled for. It was concluded that shift work is associated with several risk factors for coronary artery disease.

The healthy-worker effect : Self-selection among Swedish shift workers
- 1992

- This paper reports a study on the 'healthy-worker effect' related to shift work. The study sample comprised 53 male applicants for blue-collar jobs. The subjects who applied for shift work (m = 30) did not differ from those who applied for day work (n = 23) regarding previous illnesses or current symptoms. However, data on self-reported sleep behaviour indicated that a higher percentage of prospective shift workers had a less rigid sleep pattern than did prospective day workers. The results suggest that there might be a self-selection to shift work by individuals with specific sleep behaviours that might facilitate future coping with odd work hours.

Sleep on the night shift: 24-hour EEG monitoring of spontaneous sleep/wake behavior
- 1989

Ingår i: Psychophysiology. - : Wiley. - 0048-5772 .- 1469-8986. ; 26:3, s. 352-358

Tidskriftsartikel (refereegranskat)abstract
- The present study sought to objectively describe the spontaneous sleep/wakefulness pattern of shift workers during a 24-hour period. Portable Medilog tape-recorders were used for ambulatory EEG monitoring of 25 male papermill workers (25-55 years) during days with night and afternoon work. The results showed that sleep after night work was two hours shorter than after afternoon work. The sleep reduction affected mainly Stage 2 and REM sleep while slow wave sleep was unchanged. In connection with night work 28% of the workers took a nap in the afternoon. These naps contained a large proportion of slow wave sleep and were, apparently, caused by the sleep deficit after the short main sleep period. The EEG recordings also revealed that 20% of the participants had sleep episodes during night work. These naps were as long as the afternoon naps, were experienced as "dozing offs" rather than naps, occurred at the time of the trough of the circadian wakefulness rhythm, and were concomitant with extreme subjective sleepiness and low rated work load. It was concluded that not only the sleep of shift workers was disturbed, but also the wakefulness--to the extent that sleepiness during night work sometimes reached a level where reasonable wakefulness could not be maintained. The latter observation is probably of special importance in work situations demanding a great responsibility for human lives or for great economic values.

Shift work and cardiovascular disease
- 1984
-
Ingår i: Scandinavian Journal of Work, Health & Environment. - 0355-3140. ; 10:Spec.issue 1, s. 409-414
-
Tidskriftsartikel (refereegranskat)abstract
- This paper reviews a number of studies which have presented results on the association between shift work and cardiovascular disease. It is suggested that many of the early studies suffer from methodological flaws which render them difficult to interpret. In studies in which incidence of disease has been computed and related to exposure to shift work, the results indicate a higher risk for cardiovascular disease among shift workers as compared to day workers. The evidence cannot yet, however, be considered conclusive.
