Women who smoke and stop during pregnancy: Who are they?

Abstract

Objectives: to identify factors involved in not stopping smoking in spite of being pregnant. Methods: standardized interviews were applied to 486 pregnant women in the pre-natal clinics of four health centers in the city of Rio de Janeiro, Brazil, between April 2003 and February 2004. Every time a smoker was identified, an additional interview, which included the Edinburgh Postnatal Depression Scale, the Fagerströn scale for nicotine dependence, and the Screening Questionnaire for Adult Mental Disorders, was carried out. Results: the prevalence of smoking, in the initial stages of pregnancy was 21.1%. Most smokers presented a low level of nicotine dependence. Thirty-six percent of them stopped smoking by the first trimester of the present pregnancy without any specific medical intervention. Important differences between those who were able to stop and those who were not were alcohol intake and number of previous attempts at abstinence. Women who stopped smoking drank less during gestation. Conclusions: stopping smoking during pregnancy seems to be linked to a non-specific drive towards the well-being of the fetus. The number of previous attempts at abstinence was positively related to stopping at the beginning of pregnancy. In spite of the prevalence of the problem, there is still inadequate support for smokers in the prenatal services.
