Although the literature claims that shift work is harmful, it overlooks the fact that that many shift workers are satisfied and stay healthy. There is little knowledge of the biological mechanisms mediating the differences in susceptibility. The present study compared satisfied and dissatisfied shift workers with respect to major anabolic and catabolic hormones. Forty-two male shift workers, wi...

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 ...

OBJECTIVES Endothelial dysfunction and alterations in heart rate variability (HRV) as well as sleep deprivation and shift work have been associated with cardiovascular disease. The aim of this study was to compare HRV and endothelial function among shift and matched non-shift workers in response to total sleep deprivation and recovery sleep under identical laboratory settings. METHODS Eleven ...

OBJECTIVES Night shift work has been linked to some chronic diseases. Modification of lifestyle by night work may partially contribute to the development of these diseases, nevertheless, so far epidemiological evidence is limited. The aim of the study was to explore association between night shift work and lifestyle factors using data from a cross-sectional study among blue-collar workers emplo...

Objective To review the published scientific literature for studies analysing the association between shift work and people’s daily health habits (as measured by diet, exercise, smoking or alcohol consumption) and adverse health outcomes such as obesity. Methods The following selection criteria were used to systematically search the literature: the studies were to be primary observational or an...

Objectives: This study aimed to evaluate and analyze the ergonomic behaviors order to select the best work shift group in an Iranian petrochemical Company, in 2010. Methods: The methodology was based on the Ergonomic Behavior Sampling (EBS), and performed using ELECTRE method. In this study 1147 behaviors were observed.

The aim of this study was to examine the relation between sleep difficulty and white blood cell (WBC) count in shift workers. This was a cross-sectional study in male Japanese workers at a synthetic fiber plant. The subjects were 212 male workers who underwent an annual workplace health checkup in April 2007. For the WBC count the blood test value from the health checkup was used. With regard t...

INTRODUCTION The reversal of the natural cycle of wakefulness and sleep may cause damage to the health of workers. However, there are few studies evaluating sleep, fatigue and quality of life of night shift workers considering the influence of small children on these variables. AIMS Evaluate the sleep time, fatigue and quality of life of night shift workers and verify the relationship between...

BACKGROUND Obesity is associated with productivity loss, but little is known about how obese workers function at work and also the role of working-time arrangements on this association is lacking. Therefore, the aim of this study was to examine the association of overweight and obesity with work functioning (WF), and to determine whether the associations differ between workers with different wo...
