Smoking and damages of reproduction: evidence of ELSPAC.
The international longitudinal prospective ELSPAC study also includes women from the Czech Republic: the results sum up data from 4530 women from City of Brno and District of Znojmo who had different exposure to active and passive smoking. Anamnestic data were collected by fulfilling the internationally unified questionnaires during pregnancy and at the 2nd month after delivery. Gynaecologists, obstetricians and pediatricians, using the unified procedures, were collecting objective data in the course of the pregnancy, delivery, monitoring health status of women and newborns. Significant differences were found between smoking and non-smoking women in the prevalence of alcohol and marihuana consumers both before and during pregnancy and after delivery. In personal health history, smoking women more often reported their self-perceived poor health, panic and loss of self-control during the delivery. In the current pregnancies, smoking women suffer more often with placenta praevia, placental abnormalities, fetal growth retardation and fetal malformations. On the other hand, the prevalence of preeclampsia was decreased among smokers. The children of mothers who were moderate/heavy smokers during pregnancy, had on average by 245 g lower birth weight, 1.22 cm shorter body length and by 0.66 cm smaller head circumference than those of non-smokers. These measures were on average also decreased in the groups of newborns whose mothers were light smokers or non-smokers heavy exposed to environmental tobacco smoke. On the contrary, the average gestational age was similar both in case of active smoking, passive smoking, and non-smoking women. In spite of the fact that most of smokers would give up smoking after getting pregnant, it is necessary to place the antismoking interventions and nutrition advisory service within the routine duty of physicians.
