BackgroundRelapsing to smoking postpartum jeopardizes a woman's health and her infant's health. Our study estimated the proportion and identified characteristics associated with postpartum relapse using a large population-based sample.Materials And MethodsWe analyzed Pregnancy Risk Assessment Monitoring System data among women with live births. Relapse was defined as smoking at survey completion among those who quit by the last 3 months of pregnancy. We assessed linear trends for relapse during 2000-2011 in 40 sites overall and individually using logistic regression. Adjusted prevalence ratios (aPRs) were calculated to assess characteristics associated with relapse during 2009-2011 (n = 13,076).ResultsDuring 2000-2011, the proportion of women who relapsed postpartum remained unchanged overall (p = 0.84) and by site (p ≥ 0.05 for each), ranging in 2011 from 30.8% to 52.2% (Wyoming-Arkansas). Characteristics associated with relapse compared with reference groups were prepregnancy daily smoking (aPR = 1.80; 95% confidence interval (CI): 1.59-2.04); age <20 years (aPR = 1.51; 1.24-1.84), 20-24 years (aPR = 1.39; 1.17-1.65), or 25-34 years (aPR = 1.26; 1.07-1.48); not initiating breastfeeding (aPR = 1.34; 1.24-1.44); not having a complete home smoking ban (aPR = 1.27; 1.14-1.42); being black non-Hispanic (aPR = 1.25; 1.14-1.38); being multiparous (aPR = 1.20; 1.11-1.28); experiencing 3-5 stressors during pregnancy (aPR = 1.12; 1.01-1.24); having an unintended pregnancy (aPR = 1.11; 1.03-1.19); and having 12 years of education (aPR = 1.09; 1.01-1.17).ConclusionsThere was no change in the proportion of women relapsing postpartum during 2000-2011. In 2011, nearly half (42%) of women relapsed after quitting smoking during pregnancy. Disparities exist by site and by maternal characteristics. A comprehensive approach maximizing tobacco control efforts and developing effective clinical interventions delivered across sectors is necessary for long-term tobacco abstinence among women.
