Abstract
A study of the biochemical and psychophysiological effects of stress in letter sorting machine (LSM) operators was conducted. The cohort consisted of 31 workers, 25 males, with 3 years of experience as LSM operators in the United States Postal Service and 21 LSM operators, 14 males, who had 2 years experience. The subjects completed a questionnaire that included items related to the work environment, job satisfaction, moods, health, and their perception of the extent to which their jobs were paced and the degree to which they would like to see their jobs paced. Blood pressure and heart rate were measured. Blood samples were collected and assayed for uric-acid, glucose, cholesterol, triglycerides, and creatinine. Twenty four hour urine samples were collected and analyzed for catecholamines. Job satisfaction decreased and boredom increased with increasing time of employment as an LSM operator. The difference between groups was not significant. The amount of machine pacing that the workers preferred in their jobs decreased with increasing years on the job. No consistent job related results were found on mood changes. No consistent trends that could be related to work were found in the biochemical parameters. The authors conclude that their findings should be regarded as preliminary. Job satisfaction gradually decreases with time of employment as an LSM operator. The biochemical data cannot be related to long term exposure to stress or job dissatisfaction. The biochemical data probably reflect variations in working conditions or situations.
