The effects of maternal smoking on infant health

Abstract

Maternal smoking has serious consequences for the developing fetus and infant, including a higher probability that the infant will be born prematurely and at low birth weight, will require admission to neonatal intensive care, and die during infancy. Data from Alabama birth certificates for births occurring between 1988 and 1991 were analyzed using log linear methods to calculate relative risks of adverse pregnancy outcomes and infant death. Smoking by mothers during pregnancy is associated with an elevated risk of infant death, low birth weight, and prematurity, controlling for mother's educational attainment, age, marital status, race, and trimester prenatal care was initiated. Smoking was also associated with a higher rate of admission to neonatal intensive care and to deaths from SIDS and respiratory causes. Reducing maternal smoking can contribute to a reduction of premature and low weight births and infant deaths. Because of the difficulty of stopping smoking, efforts need to be directed at preventing younger women from beginning to smoke.
