Maternal marijuana use does not increase the risk of adverse obstetrical outcomes or fetal anomalies, but does increase the risk for small for gestational age and neonatal intensive care unit admission.

Obese women receiving the same dose of misoprostol as non-obese women have higher rates of failure to achieve active labor, an effect not seen with mechanical ripening.

The absolute ΔEFW was lower in normal-weight women; however, the percentage error of the EFW was similar between women of varying BMI classifications, as was the rate of substantial error and the rate of underestimation of the EFW.

MP appears to have similar efficacy and safety when compared with other cervical ripening agents in pregnancies complicated by SGA.

Although DM alters the biometric measurements of the fetus with increasing thoracoabdominal size, there are no clinically significant alterations in the accuracy of sonography for FW prediction when performed near delivery. Sonography is highly specific for birth weight greater than 4000 g, which is helpful for delivery planning and management.
