title: Determinants of lead level in umbilical cord blood.
abstract: Lead levels were measured by atomic absorption spectrophotometry in umbilical cord blood samples of 205 consecutively born neonates and venous blood in 62 of the mothers. The mean (+/- SD) cord blood lead level was 4.7 +/- 12.1 microg/dL. In the sub sample of 62 mother-baby pairs, the mean (+/- SD) cord blood lead levels were 1.6 +/- 2.5 microg/dL and 2.0 +/- 2.1 microg/dL, respectively. According to CDC risk categories, 92% babies were in Class I of which 87% had lead levels below 5 microg/dL. The mean (+/- SD) birthweight in <5 microg/dL category was 2640 +/- 445 grams as compared to 2617 +/- 408 grams in >5 microg/dL category. The mean (+/- SD) gestational ages were 39.1 +/- 2.0 weeks and 38.1 +/- 2.0 weeks, respectively in the two groups (P=0.014). On multivariate linear analysis, lower gestational age significantly correlated with higher cord blood lead level.
