Objectives: Nicotine addiction and the inability of a large part of pregnant smokers to quit is one of the main preventable causes of morbidity and mortality during the perinatal period. The aim of this study is to investigate nicotine dependence and overall smoking habits of pregnant smokers and to possibly correlate them with smokers' social and demographic characteristics. Materials and methods: One hundred and fourteen pregnant smokers answered an electronic questionnaire consisting of 59 questions, which was divided into six sections. The questionnaires were filled out by participants from many regions of Greece and Cyprus. Results:Before their pregnancy, women smoked 19 cigarettes per day on average, while during their pregnancy they dropped to eight cigarettes per day; 65.8% of respondents stated that their husband smoked, while 58.8% answered that they had been exposed to secondhand smoke; 13.2% of pregnant smokers stated that they had had depression at some point in their lives and 14.9% reported having undergone domestic violence; 55.3% of respondents acknowledged that smoking was responsible for a variety of adverse effects to the fetus; and 97.4% of pregnant women did not follow a smoking cessation counseling program, compared to just 2.6% who did. Conclusions:The pregnant smokers in our study did not have appropriate information about the available smoking cessation services, which were not generally considered to be useful for them, and consequently they did not utilize cessation assistance. The resistance towards quitting smoking, which was observed in the sample, may also be attributed to the lack of specialized smoking cessation services in maternity hospitals in Greece.
