title: [Use of lead-glazed ceramic as a source of exposure in children of marginalized indigenous zones of Oaxaca, Mexico].
abstract: OBJECTIVE
  To find out whether the use of lead-glazed ceramic (LGC) is associated with blood lead levels in indigenous schoolchildren from Oaxaca, México.
  
  
  METHODS
  We evaluated LGC use at home as a primary source of lead exposure in 387 indigenous schoolchildren in Oaxaca in May 2001.
  
  
  RESULTS
  We found an adjusted difference of 3.9μg/dl (p<0.01) in blood lead levels (BLL) among children reporting to use (82%) LGC at home vs those who didn't. BL levels greater or equal than 10 and 20 μg/dl were observed in 60 and 27% of children, respectively.
  
  
  CONCLUSIONS
  Lead poisoning from LGC use could remain a concern for public health in Mexico, where there is a need to provide care and further study to verify its effect on BLL.
