OBJECTIVES ': 'This study examined the effects of psychosocial job strain on the excretion of neuroendocrine stress hormones (adrenaline, noradrenaline, and cortisol) on workdays and days off.

'

'

METHODS ': 'Japanese female health care providers (N=16) filled out Karasek`s job content questionnaire and had their neuroendocrine excretions (ie, urinary catecholamines and salivary cortisol) measured on a day off and on two workdays (one day shift and one night shift). After control for age and job experience as covariates, a repeated-measures analysis of variance was carried out.

'

'

RESULTS ': 'Noradrenaline excretion was significantly greater over time in the high-strain group than in the low-strain group, and that of the high-demand group was significantly greater over time than that of the low-demand group. Adrenaline excretion did not significantly differ between the groups. The group with high supervisory support had significantly higher adrenaline excretion than the group with low supervisory support. The concentration of salivary cortisol on a dayshift was significantly lower, but marginally, in the high-strain group than in the low-strain group.

'

'

CONCLUSIONS ': 'Psychosocial job strain is associated with greater noradrenaline excretion over time. This finding suggests unwinding sympathetic nervous activity. The low cortisol levels of the high-strain group may indicate circadian rhythm disturbance induced by job strain. Supervisory relationships may have a particular influence for the studied occupation because the participants had more administrative contact with supervisors than support at the worksite; therefore, supervisory support may increase adrenaline excretion.
