Smoking and adolescent pregnancy outcome.
Birth weight, length of gestation, fetal/neonatal death, and admission to neonatal intensive care were examined for 265 adolescents who smoked during pregnancy and 510 nonsmokers. After adjusting for potential confounding variables, adolescent smokers had infants weighing 222 g less than nonsmokers. Smokers were also 3.1 times more likely to have a small-for-gestational-age infant compared to the nonsmokers. Smoking status had little effect on low birth weight (less than 2500 g), preterm delivery (less than 37 weeks gestation), fetal/neonatal death, or neonatal intensive care admission. Attributable risks suggested that small-for-gestational-age births to adolescents potentially could be reduced by up to 40% and adolescent low birth weight reduced by as much as 14.5% if smoking during pregnancy was stopped.
