- The aim of this study was to evaluate the relationships between job stress and indicators
of autonomic nervous system activity in employees of the manufacturing industry. A total
of 140 employees from a company that manufactures consumer goods (i.e., diapers and paper
towels) were recruited for participation in this study. Job stress was assessed using Karasek’s
Job Content Questionnaire. Heart rate variability (HRV) was measured using a heart rate monitor,
and urinary catecholamines were measured by an HPLC-ECD. Information on demographic
characteristics, previous job history, smoking status and alcohol consumption was also collected.
Job stress did not have a significant effect on HRV or catecholamines. However, low-frequency
HRV was significantly higher in the high-strain group of subjects with a short duration of employment.
Low- and high-frequency HRV were higher in the high-strain group than in the low-strain
group, but these differences were not statistically significant. The results of the present study
indicate that low-frequency HRV was significantly higher in the high-strain group of subjects
with a short duration of employment. In addition, the results of this study show that HRV can
be used as a potential physiologic indicator of job stress in employees with a short duration of
