ObjectivesWe assessed whether smoking cessation improved among pregnant smokers who attended Women, Infants and Children (WIC) Supplemental Nutrition Program clinics trained to implement a brief smoking cessation counseling intervention, the 5As: ask, advise, assess, assist, arrange.MethodsIn Ohio, staff in 38 WIC clinics were trained to deliver the 5As from 2006 through 2010. Using 2005-2011 Pregnancy Nutrition Surveillance System data, we performed conditional logistic regression, stratified on clinic, to estimate the relationship between women's exposure to the 5As and the odds of self-reported quitting during pregnancy. Reporting bias for quitting was assessed by examining whether differences in infants' birth weight by quit status differed by clinic training status.ResultsOf 71,526 pregnant smokers at WIC enrollment, 23% quit. Odds of quitting were higher among women who attended a clinic after versus before clinic staff was trained (adjusted odds ratio, 1.16; 95% confidence interval, 1.04-1.29). The adjusted mean infant birth weight was, on average, 96 g higher among women who reported quitting (P<0.0001), regardless of clinic training status.ConclusionsTraining all Ohio WIC clinics to deliver the 5As may promote quitting among pregnant smokers, and thus is an important strategy to improve maternal and child health outcomes.Published by Elsevier Inc.
