A recent study examines the relationship between postpartum depression (PPD) and cigarette smoking. The study sample consisted of 29,654 U.S. women who reported smoking in the 3 months prior to pregnancy and for whom data on PPD were available from the Pregnancy Risk Assessment Monitoring System (PRAMS).
A high proportion (47%–63%) of women who quit smoking during pregnancy relapse during the postpartum period.   Being able to identify those women at highest risk for relapse may help to devise strategies for preventing relapse.
While many women who smoke successfully quit smoking during pregnancy, most of these women return to smoking within 12 months of delivery. Several studies have suggested that certain factors may increase the risk of postpartum relapse, including unwanted pregnancy, multiparity, and stressful life events. Two recent studies indicate that postpartum depressive symptoms may also increase the risk of smoking relapse after delivery.
