Smoking during pregnancy adversely affects the health of both the mother and her baby. Maternal smoking can result in miscarriages, premature delivery, and sudden infant death syndrome. Smoking during pregnancy nearly doubles a woman’s risk of having a low birth weight baby, and low birth weight is a key predictor for infant mortality. In addition, smoking also increases the risk of preterm delivery. Low birth weight and premature babies face an increased risk of serious health problems during the infant period, as well as chronic lifelong disabilities such as cerebral palsy, mental retardation, and learning problems.
