Little is known about the motivational background of smoking after a period of nicotine abstinence during pregnancy. The study examines the intention to resume smoking (IRS) in the post-partum period and its predictive value for smoking within 12 months post-partum. In a sample of 301 women recruited from obstetric wards who reported having stopped smoking during pregnancy, data on IRS, sociodemographic variables, recent smoking behaviour and smoking in the social network were collected.

... status was assessed 6 and 12 months after pregnancy. Among all formerly smoking women, 39 (13%) intended to resume smoking and 262 (87%) intended to maintain abstinence. Women with IRS returned to smoking more often than women without IRS [77 versus 45%, odds ratio (OR) 5 4.1, 95% confidence interval (CI): 1.89-9.05]. In a logistic regression model, IRS (OR 5 3.7, 95% CI: 1.51-9.01) and number of months currently abstinent (OR 5 0.9, 95% CI: 0.76-0.96) attained statistical significance. IRS proved to be the main predictor for relapse; yet, women with no IRS are at risk to restart smoking again, too. IRS offers a cue for tailoring interventions.
