  1. Lorry drivers'work stress evaluated by catecholamines excreted in urine.

    Article - En anglais

    Objectives-To evaluate lorry drivers'work stress by measurement of adrenaline and noradrenaline excreted in the urine, and to find out which factors in their working situation are related to the excretion rates of these catecholamines.

    Methods-The urinary excretion of adrenaline and noradrenaline of 32 lorry drivers, who also had loading and unloading activities to perform, was studied for one working day and one rest day.

    Each driver was asked to provide six urine samples on both days.

    Results

    For all samples, except the first (overnight) sample, the excretion rates of both catecholamines on the working day were higher than those on the rest day.

    Psychosocial job strain did not significantly contribute to the proportion of variance explained in the excretion rates of both catecholamines.

    Conclusions-The excretion rates of adrenaline and, especially, noradrenaline on the working day were higher than those found in earlier studies among professional drivers and insufficient recovery took place after the work was ended.

    The only association between excretion rate on the working day and work stressors was found for noradrenaline and physical workload.

    The drivers'sympathoadrenal medullary reactivity to everyday work demands shows the characteristics of sustained activation.
