Determination of smoking prevalence within the representative sample of pregnant women in Vojvodina is facilitating insight into dispersion of the most frequent behavioral risk factor in one of the most vulnerable population categories, as well as consideration of influence of smoking to pregnancy outcome. The survey was performed on representative sample of three months cohort, 726 pregnant women in Vojvodina, by stratified two-stage random cluster sampling with an aim to assess: prevalence and intensity of smoking immediately before cognition of pregnancy, at each trimester during the pregnancy and at 3 and 6 months after delivery, exposure to environmental smoke at home, rate and reasons for smoking cessation up to 6 months after delivery and pregnancy outcome by infants` birth weight, body height and circumference of the head analysis. Three questionairres were used as survey instruments, composed with consideration of survey protocols used for attainment of smoking prevalence with... pregnant women in earlier studies, pilot-study results and form for transcript of variables from the Newborn Infant Record. It is determined that smoking prevalence during pregnancy is high (40.9 percents smoked at some point during the pregnancy), as well as exposure to tobacco smoke at home (56.2 percents lives in a home with at least one smoker whilst 83.5 percents allowes smoking at home). More than one third of pregnant women (39.2 percents) attemped to quit smoking after the delivery, majority immediately after the birth (85.3 percents), but over 55 percents continued to smoke afer only one week. Almost one quarter of pregnant women (24.4 percents) that quit smoking during the pregnancy is still abstaining three months after the birth, and nearly one fifth of examinees (19.3 percents) is successful even six months after giving birth which could be considered as definite efficacy of cessation. Smoking in pregnancy was significantly influential to infants` birth weight, body height and circumference of the head. Infants whose mothers smoked immediately before the pregnancy, and during the course of pregnancy, had lower birth weight compared to infants of nonsmoking mothers (for 95.3 g i.e. 86.3 g), while body height was smaller for 0.59 cm, i.e. 0.54 cm. Arrear in birth weight and birth height was more expressed in infants whose mothers smoked constantly during the course of pregnancy and more than 20 cigarettes per day in average than in mothers smoking less frequently and less intensively. Circumference of the newborns` head was affected by frequency and quantity of consumed cigarettes. Infants whose mothers smoked constantly during the pregnancy and more than 20 cigarettes per day in average had smaller circumference of the head for approximately 1 cm compared to infants delivered by mothers who smoked occasionally and less cigarettes. The results impose an obligation for establishing population-specific aims for decrement of smoking prevalence among pregnant and post-partum women. Vulnerability of this population group draws attention to urgency of action(s).
