摘      要：ABSTRACT:Antibiotic exposure during pregnancy may affect the neurodevelopment of children,but biomonitoring-based population studies on this class of new pollutants are *** conducted a prospective birth cohort study of 2860 mother−child pairs,measured the urinary concentrations of 41 antibiotics and their two metabolites over three trimesters,and assessed children’s autism spectrum disorder(ASD)symptoms at 3 years of *** examined the associations between prenatal antibiotic exposure and children’s ASD *** least absolute shrinkage and selection operator regression screened for Tetracycline and Ofloxacin as important predictors of ASD *** Poisson regression models revealed that maternal Tetracycline exposure throughout pregnancy increased the risk of ASD symptoms(RR:1.66,95%CI:1.14,2.40).Maternal Tetracycline exposure during the first(RR:1.74,95%CI:1.13,2.68)and third trimesters(RR:1.86,95%CI:1.16,3.00)increased the risk of ASD symptoms in boys,and Ofloxacin exposure during the first trimester(RR:1.47,95%CI:1.07,2.02)increased the risk of ASD symptoms in *** dose-dependent relationships between prenatal antibiotic exposure and ASD symptoms were validated by restricted cubic *** exposure to Tetracycline and Ofloxacin may increase the risk of ASD symptoms in children,and the first and third trimesters might be the key windows.
