maternal intake of pesticide residues from fruits and vegetables in relation to fetal growth objectives to examine the associations of maternal intake of fruits and vegetables fvs considering pesticide residue levels with fetal growthmethods we studied 1777 mothers 1275 white 502 nonwhite and their infants from project viva a prospective prebirth cohort 19992002 we categorized fvs as containing high or low pesticide residues using data from the us department of agriculture we then used a food frequency questionnaire to estimate each participants intake of high and low pesticide residue fvs in the first and second trimester the primary outcomes were smallforgestationalage sga 10th percentile in birthweightforgestationalage largeforgestationalage lga 10th percentile in birthweightforgestationalage and preterm birth gestational age 37weeks we also evaluated whether the associations between high pesticide residue fv intake and birth outcomes were modified by raceethnicityresults 55 of newborns were sga 137 were lga and 73 were preterm intakes of high or low pesticide residue fvs regardless of pregnancy trimester were not associated with risks of sga lga or preterm birth in addition the associations of high pesticide fv intake with sga and lga were not modified by raceethnicity however we observed heterogeneity in the relationship between first trimester high pesticide fv intake and risk of preterm birth by raceethnicity p value for interaction001 although this relationship did not persist after correction for multiple comparisons bonferroni corrected level of significance p28103conclusions there were no clear associations between high or low pesticide fv intake during pregnancy with sga lga or preterm birth
