Organophosphate (OP) pesticides may accumulate in pregnant agricultural workers, resulting in adverse effects on the growth and development of the fetus and neonates. This study aims to evaluate a possible association between prenatal urinary OP metabolite levels among pregnant agricultural workers and birth outcomes of infants. This study also investigated the factors associated with urinary OP metabolites among pregnant agricultural workers. The spot urine samples were collected and analyzed for six OP metabolite levels. Birth outcomes data were abstracted from medical records. Multiple regression analysis found that gestational age at childbirth was negatively associated with diethylphosphate (DEP) levels (β = −0.073; 95% CI, −0.121, −0.024). Apgar score at 1 and 5 min after birth were negatively associated with diethyldithiophosphate (DEDTP) levels (β = −0.036; 95% CI, −0.069, −0.003; and β = −0.034, 95% CI, −0.057, −0.011, respectively). In addition, DEDTP levels were negatively associated with maternal age (β = −0.181; 95% CI, −0.339, −0.023), and dimethylphosphate (DMP) levels were positively associated with frequency of agricultural work during pregnancy (β = 31.554; 95% CI, 0.194, 62.914). Our results indicate that prenatal OP exposure can cause adverse birth outcomes in babies. Therefore, it is necessary to develop an effective strategy for reducing prenatal exposure to OP pesticides.
