This study was conducted to test the hypothesis that breast-fed infants of smokers are smaller in size at 1 year of age than breast-fed infants of nonsmokers.
Three groups of infants were selected from all singletons born to women who were seen for prenatal care in their 6th month of pregnancy at a health maintenance organization in Seattle, Washington, between January 1982 and April 1983.
Breast-fed infants of smokers (n=74) were compared with breast-fed infants of nonsmokers (n=195) and with bottle-fed infants of smokers (n=64).
Mothers were interviewed at 1 and 3 months after delivery ; both the mother and the infant were seen at 1 year.
Among breast feeders, smokers'infants were twice as likely as nonsmokers'infants to have body mass more than 1 standard deviation above the mean (relative risk=2.04,95% confidence interval 1.15-3.61).
