A psychosocial and biomedical comparison between men in six contrasting service occupations

Abstract

A study of psychosocial job factors and physiological states was conducted using 150 men, aged between 25 and 60, working in six widely different occupations—freight handlers, aircraft mechanics, air traffic controllers, physicians, waiters and symphony musicians. The aim of the study was to characterize any differences in physiological parameters in relation to differences in psychosocial job characteristics. Analyses of variance were used to test differences between groups. The results indicated that waiters, the group reporting the most unfavourable working conditions, tended to have many cardiovascular risk factors. Physicians, who had relatively few cardiovascular risk factors, reported high decision latitude and many emotional reactions in their daily life and had relatively high cortisol and low prolactin levels in plasma.
