Objective: to assess the prevalence of current smoking during pregnancy, its risk factors and consequences as well as to assess what intervention, if any, was offered. The results of the study may help to better target this specific group of smokers.
Methods: in this study, 318 pregnant women were interviewed in a Prague obstetrics center during 2004 and 2005 prior giving a birth. Mothers were questioned about their cigarette smoking, educational and social background and intervention provided by their primary gynecologist. Additional data were obtained from hospital records. To verify their responses about smoking, levels of expired carbon monoxide were measured with a Bedfont Micro Smokerlyser.
Results: the prevalence of current smoking during pregnancy was 12 %. None of the smokers had university degree. 72 % of smokers did not have even high school diploma compared to only 14 % of non-smokers without high school diploma. The study also confirmed a well known fact that smokers come from much poorer social backgrounds compared to non-smokers. Average length of gestation in smokers was 270 days, in non-smokers 279 days. Average birth weight of smoker's baby was 2913 g; of non-smoker's baby 3468 g. 23 % of infants born to smoking mothers were immature compared to 1 % of immature infants born to non-smokers. None of the smokers recieved appropriate intervention. 22 % of mothers were not asked about their smoking at all. Brief intervention should be incorporated into compulsory guidlines for prenatal care.
