IntroductionPrevious work has identified predictors of relapse to smoking postpartum among parenting people who quit during pregnancy, but less is known about the time course of postpartum relapse. The study goals were to document patterns and correlates of smoking resumption among people who quit smoking during pregnancy and were motivated to remain abstinent.Aims and MethodsWe conducted a secondary analysis among participants in a randomized controlled trial of postpartum-specific smoking relapse prevention interventions who self-reported no smoking since the quit date to delivery (n= 280). Participants provided expired air samples of carbon monoxide, and completed self-report measures of mood, perceived stress, and demographic and pregnancy-related information. Timeline follow-back interviews were conducted at the end of pregnancy and 12-, 24-, and 52-weeks postpartum.ResultsThe largest group (49.7% of participants) belonged to a trajectory reflecting abstinence across 1 year postpartum. Another 13% remained abstinent 5–6 months after delivery. However, one in five started to smoke consistently within 100 days after delivery, and 16% relapsed in a pattern that can be described as inconsistent smoking. Participants with more prior quit attempts and those who smoked more cigarettes prior to their quit attempt were more likely to relapse within 100 days of delivery.ConclusionsThe first 3 months postpartum represent a critical window for relapse prevention, given that most individuals who relapsed did so in the first 100 days or so after delivery. Assessing prior smoking history can help identify pregnant people who will need additional support in the early postpartum period.ImplicationsRelapse to smoking during the year after childbirth is common, but the time course of relapse after delivery is poorly understood. This study provides evidence for 4 distinct trajectories of relapse, and highlights variables linked to early relapse that may improve efforts to target and time intervention efforts. Specifically, assessing age at initiation, quantity of tobacco use prior to quit attempt, and number of previous quit attempts will identify pregnant people at greatest risk of early relapse. These findings also suggest that additional support early in the postpartum period is crucial for most people in the postpartum who will relapse.
