ABSTRACT
The aim of this work was to evaluate plasma Pb levels in pregnancy and their birth outcomes implications. For analysis (n = 396 pregnant women with 56 fetal-maternal clusters), plasma samples were diluted quantitatively with a matrix modifier solution and Pb levels were measured using an atomic absorption spectrophotometer (AA500FG). Compared to women with a normal Body Mass Index, underweight, overweight and obese women group had increased levels of plasma Pb (t-test, p=0.0395). Levels of plasma Pb were also observed in women with a family history of preeclampsia and diabetes mellitus (t-test, p=0.0050 and 0.0312, respectively). At delivery, plasma Pb levels were significantly higher in women as compared to prenatal period [means (±SD), 3.387 µg/L (± 0.965) in 37-42 weeks, 2.060 µg/L (± 0.980) in 20-36 weeks and 1.543 µg/L (± 0.709) in 10-19 weeks, ANOVA, p < 0.0001] and newborns showed higher plasma Pb levels than their mothers [means (±SD), 2.304 µg/L (± 0.644) versus 2.067 µg/L (± 1.067), t-test, p < 0.0001]. Globally, plasma Pb levels show no significant linear negative correlation to all of the birth outcomes (weight, height, ponderal index, Apgar score, gestational age, head circumference).
