Factors Associated With Smoking Cessation in Pregnancy

Background: Smoking during pregnancy poses a major health risk to pregnant smokers and their children. Pregnancy could be an opportune moment for cessation. Yet many smokers do not quit during pregnancy. This study aims to explore potential influencing factors for successful smoking cessation in pregnancy. Methods: Cross-sectional data was collected in an anonymous online survey (n=358). Data of n=60 women between the 24th week of pregnancy and four months postpartum was analysed. Variables showing significant differences between women who successfully quit smoking during pregnancy (“ex-smokers”, n=40) and women who were still smoking at the time of the survey (“smokers”, n=20) were included in a logistic regression to identify potentially important influencing factors. Results: Ex-smokers showed higher education levels, were employed, had a planned pregnancy, abstained from alcohol during pregnancy, and scored lower on the Fagerström test for cigarette dependence. They showed greater satisfaction with life and higher scores on the personality trait “agreeableness”. In the regression model, a planned pregnancy, alcohol abstinence and higher agreeableness scores increased the odds of being an ex-smoker. Conclusions: Planned pregnancies could be particularly suitable for smoking cessation. Alcohol should be considered, as abstinence could contribute to smoking cessation. A personality characterised by high agreeableness could be beneficial at least in addition to other factors.
