Association of umbilical cord blood lead with neonatal behavior at varying levels of exposure.

ABSTRACT:

Background

In the light of the ongoing debate about lowering the cut-off for acceptable blood lead level to <5 microg/dL from the currently recommended level of <10 microg/dL, we considered whether prenatal exposure to varying levels of lead is associated with similar or disparate effects on neonatal behavior.

Methods

Using Brazelton's Neonatal Behavioral Assessment Scale (NBAS), an epidemiological approach and robust statistical techniques like multivariate linear regression, logistic regression, Poisson regression and structural equations modeling analyses we estimated the simultaneous indirect effects of umbilical cord blood lead (CBL) levels and other neonatal covariates on the NBAS clusters.

Results

We observed that when analyzed in all study subjects, the CBL le
