aNon-adjusted for potential confounders
bAdjusted for potential confounders
Model A: Adjusted on mother’s age at delivery, marital status, BMI at recruitment, infection, smoking status during pregnancy, ΣPCBs (CB-138, CB-153 and CB-180 expressed in ng/g of lipid), mothers total blood levels of lead (ng/ml)
Model B: Model A + previous pregnancies history (preterm infant and low birth weight infant) in multipara only (N = 234)
cTotal lipids were not taken into account in these models
