^aAdjusted for maternal age, height, weight before pregnancy, parity, smoking and alcohol intake status during pregnancy, annual household income, gestational age, infant gender and blood sampling period in a multiple linear regression model. For head circumference, adjusted model also included delivery type
^bAdjusted for maternal age, height, weight before pregnancy, parity, smoking and alcohol intake status during pregnancy, annual household income, gestational age and blood sampling period in a multiple linear regression model. For head circumference, adjusted model also included delivery type
^cPartial regression coefficient represents the expected change in dependent variables as a result of a tenfold change in MEHP level, because MEHP level was log₁₀-transformed
