Abstract

Background: Due to its long-term persistence in the environment and its ability to cross the placental barrier, prenatal p,p'-dichlorodiphenyldichloroethene (DDE) exposure continues to be a public health concern. This study aimed to evaluate the association between prenatal DDE exposure and child growth, at birth and during the first year of life.

Methods: 253 pregnant women were recruited between January 2001 and June 2005 in a prospective cohort in Morelos, Mexico. Serum levels of DDE were measured during each trimester of pregnancy by gas chromatography with an electron capture detector. Using the generalized mixed-effects models, the association between DDE and child growth parameters (weight-for-age, length-for-age, weight-for-length, BMI-for-age and head circumference-for-age Z-scores) from birth to 1 year of age was assessed. Maternal dietary intake was considered as covariable among others.

Results: DDE levels were 6.3±2.8 ng/mL (first trimester), 6.6±2.9 ng/mL (second trimester), and 7.6±2.9 ng/mL (third trimester). After adjusting for potential confounder variables, no significant associations were observed with prenatal DDE exposure and each of the selected parameters.

Conclusions: Our results show no evidence of an association between prenatal DDE exposure and child growth during the first year of life.
