The aim of the study was to evaluate the effectiveness of antismoking counseling for postpartum women. The study was conducted between 2004-2006 in Lodz district. The study population consisted of 199 women and among them 100 were included into the intervention group and 99 to control one. Antismoking intervention and control activities were conducted among the women who quit smoking during pregnancy and maintained smoking abstinence after delivery. There were no statistically significant differences regarding the socio-demographic characteristic between intervention and control group. The women who received antismoking advice relapsed into the smoking less frequently than the women from the control group (26% vs. 56%; OR = 0.25; 95% CI 0.15-0.51). The antismoking counseling for postpartum women is the effective tool to help them to maintain smoking abstinence.
