[The effect of tobacco smoking on maternal weight gain and the neonatal results].
Our aim was to investigate the effects of smoking till term on maternal weight increase and on the foetus after delivery. The study is prospective and includes a group of 238 pregnant smokers consulted at the Antenatal clinics of the 3rd county polyclinic, Pleven. 115 of them smoked regularly until term at least 5 cigarettes weekly (48.32%), while 123 stopped smoking prenatally (45.9%). Utilizing a special test these two groups were compared based on their pre-delivery weight and the weight of their foetuses.


RESULTS
The women who stopped smoking increased in weight with 16.6 kgs (SD-14.5), while those who smoked till term thrived with 13.2 kgs (SD-11.7) (Pt 0.001). This greater increase in maternal weight is connected with a 3.1 times more frequent delivery of babies weighing more than 4000 gr. All neonates with LBW were in the group of smokers, as well as those with foetal demise (perinatal deaths = 12.76%.


CONCLUSIONS
In the studied group stoppage of smoking is connected with less risk of inadequate increase of weight, LBW and their foetuses more frequently weigh more than 4000 gr.
