Título Association of working hours with biological indices related to the cardiovascular system among engineers in a machinery manufacturing company
Información bibliográfica Oct. 1999, Vol.37, No.4, p.457-463. 17 ref.
Resumen A field survey of 278 engineers (20-59 years) in a machinery manufacturing company was conducted to investigate the association of working hours with biological indices related to the cardiovascular system (heart rate variability, blood pressure and serum levels of magnesium, dehydroepiandrosterone sulfate (DHEA-S) and cholesterol). Average working hours (defined as hours at workplace plus half of the commuting time) and sleeping hours in this study were 60.2 ± 6.3hr/week and 6.6 ± 0.8hr/day respectively. There was no significant relationship between working hours and biological indices related to the cardiovascular system, but sleeping hours had a strong negative correlation with working hours. Furthermore, the serum DHEA-S level was significantly related to sleeping hours positively. These two results indicate that long working hours might lower the serum DHEA-S level due to the reduction of sleeping hours.
