  1. Anthropometric measurements were made at birth (mean ± SD = 1.4 ± 1.2 days old). OPE metabolite concentrations were log2-transformed and multiple linear regression models were adjusted for maternal age at delivery, income, pre-pregnancy BMI, parity and infant sex. Overall effect estimates are presented since all exposure*sex interaction terms were non-significant. Gestational age at delivery is reported in weeks; Anthropometric measures include: weight (kg), length (cm), head circumference (cm), and abdominal circumference (cm)
