Abstract: (513 Views)
Background & Aims: Lead (Pb) may cause cognitive impairments in both recent acute and chronic exposures. In this study, the effect of Pb exposure on the relationship between neurobehavioral characteristics and productivity was evaluated among battery manufacturing workers.
Materials and Methods: In general, 179 production workers and 179 office workers participated in this cross-sectional study. Venous blood sampling was used to measure the level of Pb in the blood. Psychomotor performance and intellectual functioning were measured using the digit symbol substitution test and the Wechsler adult intelligence scale-revised, respectively. Finally, productivity was assessed using a health and work performance questionnaire.
Results: Exposed workers had a significantly higher level of Pb, while a lower level of intellectual functioning and psychomotor performance than non-exposed workers. The results of linear regression indicated that the increase in the blood level of Pb was accompanied by a significant decrease in the positive effects of intellectual functioning on productivity. However, exposure to Pb had no effect on the relationship between psychomotor performance and productivity.
Conclusion: Occupational exposure to Pb affected the relationship between psycho-diagnostic performance and productivity and could induce neurobehavioral dysfunction in the exposed workers. For the early detection of cognitive impairment, the neurobehavioral assessment is recommended to be implemented in work assessments.
