Two hundred fifty-six pregnant women who had quit smoking were classified i
nto the precontemplation (PC), contemplation (C), preparation (PA), or acti
on (A) stages of change for postpartum smoking cessation based on a 3-item
algorithm assessing personal goals, self-efficacy, and smoking behavior. Lo
gistic regression and event history analyses indicated group differences in
return to smoking at 6 weeks and 3, 6, and 12 months postpartum. The perce
ntage of women who returned to postpartum smoking was highest in the precon
templation stage and decreased with each subsequent stage, that is, at 6 we
eks 83% of PCs, 64% of Cs, 35% of PAs, and 24% of As had returned to smokin
g. Results lend support for the stages of change for postpartum smoking abs
tinence. Stage-based interventions may be developed to assist women in main
taining abstinence postpartum.
