Which statement about smoking cessation during pregnancy best communicates the benefits?

• A. It will not reduce risk of neural tube defects.
• B. It will increase the oxygen supply to the fetus.
• C. It will reduce the risk of preterm labor and premature rupture of membranes.
• D. It will decrease the risk of intrauterine growth restriction and low birth weight.

Answer: (D)

Quitting smoking during pregnancy most clearly communicates a direct, meaningful benefit for the baby's growth. Tobacco exposure impairs placental blood flow and reduces fetal oxygen and nutrient delivery, so stopping eliminates much of that ongoing insult and allows the fetus to grow more normally. The resulting improvement in fetal growth translates into a lower risk of intrauterine growth restriction and low birth weight, outcomes that are precisely tracked in prenatal care and have clear implications for the infant’s immediate and long-term health. While stopping smoking can also improve oxygen delivery and may reduce other risks, the strongest, most reassuring message to emphasize is the decreased likelihood of growth restriction and low birth weight.
