Abstract

OBJECTIVES
This study was carried out to assess psychosocial distress of lead workers and to examine the relationship between lead exposure indices and psychosocial distress.
METHODS
The study design was cross-sectional and research subjects were 234 lead workers in primary smelting industry. General characteristics, job characteristics and social support were obtained by self-administered questionnaire and history taking. Psychosocial distress was measured using PWI(Psychosocial Well-being Index), a 45-item self-administered instrument. Blood lead(PbB), zinc protoporphyrin(ZPP), -aminolevulinic acid in urine(ALAU) were selected as indicators of lead exposure.
RESULTS
There was significant difference in PWI according to lead exposure level and job characteristics. The results of correlation analysis showed that PWI was significantly correlated with PbB(r=0.203, P=0.002).
CONCLUSIONS
Our results supported the association between lead exposure and psychosocial distress. The inclusion of psychosocial distress measurement as a special health examination for lead workers was highly recommended for the effective health management.
