title: [Association between low blood lead exposure and nervous system symptoms].
abstract: OBJECTIVE
  To explore the association between low blood lead exposure and nervous system symptoms among the workers exposed to oil paint.
  
  
  METHODS
  Through cluster sampling, workers with occupational oil paint exposure in 2 factories were selected to conduct a questionnaire survey, biochemical detection and health examination. χ2 test and unconditional logistic regression analysis were performed for the determinants analysis.
  
  
  RESULTS
  A total of 525 oil paint workers completed the survey, in whom, 55 (10.5%) were blood lead positive, the mean of blood lead concentration was (0.0884±0.0539) mg/L, 278 (52.95%) had nervous system like symptoms and 69 (13.14%) had peripheral neuropathy symptoms. Multinomial logistic regression analysis showed that working age (OR=1.827), drinking (OR=1.607), health status (OR=3.862), blood lead (OR=1.983) were risk factors for nervous system like symptoms. Working age (OR=2.282), and drinking (OR=2.704) were risk factors for peripheral neuropathy.
  
  
  CONCLUSIONS
  Low blood lead exposure might be associated with nervous system like symptoms.
