Background: Secondhand smoke exposure increases an infant's risk of morbidity and mortality. We provide state-specific estimates for and characterize postpartum women with complete smoke-free home rules.

Methods: Data were analyzed from 26 states and New York City (n= 37,698) from the 2010 Pregnancy Risk Assessment Monitoring System, a population-based survey of women who recently delivered live-born infants. We calculated state-specific estimates of complete rules and assessed associations between complete rules and selected characteristics.

Results: Overall, 93.6% (95% CI: 93.1–94.1) of women with recent live births had complete smoke-free home rules (86.8% [West Virginia] to 98.6% [Utah]). Demographic groups with the lowest percentage of rules were women who smoked during pregnancy/postpartum (77.6%), were non-Hispanic Black (86.8%), never initiated breastfeeding (86.8%), <20 years of age (87.1%), <$15,000 annual income (87.6%), <12 years of education (88.6%), unmarried (88.6%), initiated prenatal care late/had no prenatal care (88.8%), had Medicaid coverage (89.7%), had an unintended pregnancy (90.3%), and enrolled in WIC (90.6%).

Conclusions: Prevalence of complete smoke-free home rules was high among women with recent live births; however, disparities exist by state and among certain sub-populations.Women, particularly smokers, should be educated during and after pregnancy about secondhand smoke and encouraged to maintain 100% smoke-free homes.
