ABSTRACT Objective To investigate how social and psychological characteristics differ between pregnant women who smoke and do not smoke. To explore associations between social and psychological features with changes of smoking habits by the end of pregnancy. Methods A case-control study was set up. Smokers cases were never-smokers and ex-smokers controls. Pregnant women (n=328) from public prenatal services were interviewed. Socio-demographic data and psychological variables – personality traits, anxiety, depression, perceived stress, maternal fetal-attachment - were measured. Saliva samples were collected to measure cotinine and to check self-informed smoking status. In addition, 66 smokers were also assessed regarding smoking habits by late pregnancy. Smoking status was defined as a dependent variable. Exposure factors were analyzed through odds ratios. Logistic models and contingency tables were employed according to the nature of variables. “Qualitative change in smoking” was defined as a dependent variable for the last evaluation, and a logistic regression model was built. Results Lower schooling, higher age, use of alcohol and drugs, living without a partner, and passive smoking showed associations with smoking. Anxiety, depression and perceived stress also exhibited positive association with smoking. Among personality traits, only Neuroticism was associated with smoking. None of the variables were associated with qualitative change in smoking by the end of pregnancy. Conclusion Smoking during pregnancy is associated with more unfavorable social conditions. Pregnant women who smoke exhibit more negative psychological states than nonsmokers, including a profile of accentuated Neuroticism. None of the investigated variables could predict changes in smoking during pregnancy.
