BPACB, creatinine based total BPA concentration. Beta coefficient represents the average decline/increase in SD score of fetal weight or fetal head circumference per gestational week. The adjusted model contains the following covariates: maternal age, educational level, ethnicity, fetal sex, weight before pregnancy, height at intake, smoking during pregnancy, alcohol use during pregnancy, folic acid use, and parity. *p < 0.05. |
