Objectives: To use recent, national data to examine correlates of smoking before, during, and after pregnancy; quitting smoking during pregnancy; and relapsing by 24 months postpartum.
Methods: Multivariate logistic regression models used data from the Early Childhood Longitudinal Study-Birth Cohort and accounted for relevant socio-demographic, clinical, and contextual covariates.
Results: Although socio-demographic characteristics including education, income, race/ethnicity, and marital status were associated with smoking at all time points, contextual factors including alcohol consumption, breast-feeding, and living with other smokers were also strongly associated with smoking, quitting, and relapsing.
Conclusions: Results of this study may facilitate the creation of more targeted interventions focusing on women at highest risk for smoking during this critical period.
