[Paired-control study on the effect of vanadium on neurobehavioral functions].
OBJECTIVE
To investigate the change of neurobehavioral functions of workers with long term exposure to vanadium.


METHODS
A total of 106 workers with exposure to vanadium were paired with workers without exposure to vanadium. The WHO-NCTB was employed to assess the neurobehavioral functions.


RESULTS
The exposure group had lower scores in the domains measuring positive moods and higher scores in the domains measuring negative moods. The exposure group had poorer performance in Santa Ana dexterity, Benton visual retention and pursuit aiming II than the control group.


CONCLUSIONS
Exposure to vanadium can adversely affect neurobehavioral functions of workers. Workers exposed to vanadium may show mood disorders, decreased vision-memory, and declined motor speed and accuracy.
