OBJECTIVES The aim of this study was to compare the psychophysiological strain related to a conventional shift schedule and new ergonomically improved two- and three-shift schedules using heart rate variability (HRV) analysis. The specific aim was to determine whether the introduced ergonomic shift arrangement had any positive effects on the psychophysiological strain such as increased HRV or d...

OBJECTIVES To explore how metabolic risk factors for cardiovascular disease (CVD) differ between shift workers and day workers in a defined population. Shift work has been associated with an increased risk of CVD. Risk factors and causal pathways for this association are only partly known. METHODS A working population of 27,485 people from the Västerbotten intervention program (VIP) has been ...

BACKGROUND Nurses, as health care providers, are insurmountably obliged to the practice of shift work. Literature has reported shift working as one of the inducing factors of burnout. Despite numerous studies in this area, there are inconsistencies on the relationship between shift working and burnout among nurses, especially in those who work in critical care settings. OBJECTIVES The aim of ...

Editor—How doctors in training view the changes in their working pattern that will be required by the European working time directive is not known. By 2004 it will limit their continuous working to no more than 13 hours in 24. As work has been defined as being at the workplace on duty, even if sleeping, this will mean shift work for those who must be resident when on call. Some British doctors ...

a study was carried out to evaluate job satisfaction of employers in a prison in 1997. the populations of study were all of staff as officiary person; contracthal and mission people. the results showed that 62.5% of the study population has beenemployed in this work because of their interest. but in the study time, 79.2% of them liked to leave their work. 73% of employers' families were not sat...

BACKGROUND Previous studies have indicated an association between shift work and cardiovascular disease. There is also considerable epidemiological evidence that hyperhomocysteinemia is an independent risk factor for cardiovascular disorders. AIMS To analyse plasma homocysteine levels in shift work bus drivers, and to investigate possible relations with sleep parameters and other biochemical ...

I use data from the 1994 Consumer Expenditure Survey as well as other sources to measure the distributional impact of green tax reforms and consumption tax reforms using both annual income and lifetime income approaches to rank households. A modest tax reform in which environmental taxes equal to 10% of federal receipts are collected has a negligible impact on the income distribution when the f...

BACKGROUND Night shift work may disrupt the normal nocturnal rise in melatonin, resulting in increased breast cancer risk, possibly through increased reproductive hormone levels. We investigated whether night shift work is associated with decreased levels of urinary 6-sulfatoxymelatonin, the primary metabolite of melatonin, and increased urinary reproductive hormone levels. METHODS Participan...

conclusions according to the results of this study, it seems that shift work can be considered a risk factor for high blood pressure changes. it is recommended that workers who are working in shifts are more at risk and need more supervision. background several factors affect the emergence of high blood pressure, among which include environmental and occupational factors. shift work is currentl...

Shift work and night work in particular have been associated with sleep difficulties, general malaise, fatigue, peptic ulceration, ischaemic heart disease, cigarette smoking and adverse pregnancy outcome. The medical conditions previously regarded as making individuals unsuitable for shift work show wide ranging patho-physiological activity and there is no published evidence for any such condit...
