Why the study?
Does working as a city bus driver affect neuro-endocrine and cardiovascular reactivity compared to free days in drivers with different absence rates?

City bus drivers with different absence rates exhibit differential neuro-endocrine and cardiovascular reactivity to work.
Occupational assessments in bus drivers warrant caution; leaves open whether reactivity differences predict absence or cardiovascular outcomes.
Two groups of six city bus drivers whose absence rate differed during the previous year were studied. Catecholamine (adrenaline, noradrenaline and dopamine) excretion rates were measured from urine samples obtained at 3-5-hour intervals over 2 working days and, for control purposes, over the first and second consecutive free days. After 3-5-hour periods of work heart rate variability was studied in laboratory conditions. In addition self-assessed workload was measured. As a major result differential neuro-endocrine and cardiovascular reactivity was found.
