To examine the association between mental health factors with smoking cessation during pregnancy and postpartum relapse. We used data from 1,416 women who participated in the Minnesota Pregnancy Risk Assessment Monitoring System survey in 2004-2006 and reported smoking immediately prior to pregnancy. Maternal mood during pregnancy, stressful life events and postpartum depression were the mental health variables. We used multivariate logistic regression to examine the association between these variables and two outcomes, smoking cessation during pregnancy and postpartum relapse. Stressful life events was associated with smoking cessation in multivariate regression models, however maternal mood was not. Smoking cessation was also associated with pre-conception smoking intensity, maternal education, and income. Maternal mood, stressful life events and postpartum depression were not associated with relapse in multivariate regression models. Breastfeeding at the time of the survey was the strongest correlate of relapse, with women who breast fed 60% less likely to resume smoking during the postpartum. Post-hoc analysis suggests that mental health variables may interact with other mitigating factors to influence smoking behavior during pregnancy. Mental health variables may be important to successful prenatal smoking cessation. Further research with larger sample sizes is needed to explore the possibility of interactive relationships between mental health variables and other co-factors on prenatal smoking cessation and postpartum relapse.
