The risk of intrauterine growth retardation (IUGR) and preterm delivery, in the group of 551 females from the area of Lódź, was related to the amount of cigarettes smoked per day. In subjects smoking more than 20 cigarettes, the risk of IUGR and preterm delivery was five times as high as in the nonsmoking females. The average weight of the newborns was found to be 510 g lower in the group of the most heavy smokers as compared with the nonsmoking subjects. The study has not provided any clear evidence for the pre-pregnancy smoking and the passive smoking as the risk factors for the pathologies under study.
在罗兹地区的551名女性群体中，宫内生长受限（IUGR）和早产风险与每日吸烟量有关。在每天吸烟超过20支的女性中，IUGR和早产风险是非吸烟女性的五倍。研究发现，与非吸烟女性相比，吸烟量最大的女性群体中新生儿的平均体重低510克。该研究没有提供任何明确证据表明孕前吸烟和被动吸烟是所研究病症的风险因素。
