Job stress did not have a significant overall effect on heart rate variability or urinary catecholamines in male manufacturing workers.

Does high job stress alter heart rate variability and urinary catecholamines in male manufacturing workers?
Heart rate variability may serve as a physiologic indicator of job stress in employees with a short duration of employment, despite no overall significant effect of stress on HRV or catecholamines.

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 employment.
Lee et al. (2010) conducted a cross-sectional in Job stress (n=140). Job stress vs. Low job strain was evaluated on Low-frequency power of heart rate variability (ln ms^2) (p=0.61). Job stress did not have a significant overall effect on heart rate variability or urinary catecholamines in male manufacturing workers.
