OBJECTIVE: Our purpose was to assess the effect of prenatal smoking cessation on maternal weight gain and infant birth weight in women who smoked at least five cigarettes per week.STUDY DESIGN: This prospective study followed up a sample of white, non-Hispanic pregnant smokers enrolled in three multispecialty clinics. By use of t tests, women quitting smoking before 28 weeks and continuing smokers were compared on total weight gain, Institute of Medicine weight gain categories, and infant birth weight.RESULTS: Quitters gained 36.6 pounds (SD 14.5) and smokers 28.9 pounds (SD 11.7) lo < 0.001). The relative risk of quitters gaining less than the Institute of Medicine minimum was 0.47 (95% confidence interval 0.27 to 0.81). Quitters also gained more than Institute of Medicine standards (relative risk 1.74, 95% confidence interval 1.21 to 2.51), and they were 3.1 times as likely to be delivered of infants weighing >4000 gm (95% confidence interval 1.18 to 7.97). The four low-birth-weight babies were born to smokers with low weight gain.CONCLUSION: In this population smoking cessation is associated with a lower risk of gaining too little by Institute of Medicine standards and also with higher risk of gaining more than the Institute of Medicine standard and having infants weighing >4000 gm. The clinical significance of these effects needs to be determined in further studies.
