Stress-Related Risk Factors.
NIOSH 1982 Feb:137-148
The impact of stress upon job design and allocation of human resources was reviewed. Studies indicated that the highest stress encountered in the workplace was associated with tasks having a high demand and low decision latitude, while lowest stress levels were associated with tasks having lowest job demand and highest job decision latitude. Sinus arrhythmia was used as a measure of stress encountered in the workplace. When operators were asked to perform the same task at either machine paced or self paced levels, more stress was associated with the self paced work, presumably as a result of the additional responsibility of timing which had to be performed during self paced but not machine paced work. However, work performance was higher at the more stressful self paced work level. Changes in non work related movements occurred less frequently in self paced than in machine paced work, and were thought to possibly reflect changes in anxiety levels associated with task performance. No differences were observed between workers doing self paced versus machine paced work with respect to rate of breathing, blood pressure and heart rate when measured by unobtrusive physiological means over the course of a year. The author suggests that a need exists for research into the possible contribution of stress to work related accidents, and the ameliorating effects that enhanced physical fitness might have upon stress levels and stress associated accidents.
