A prospective study of 1004 consecutive deliveries was carried out to investigate the effect of passive smoking during pregnancy on a set of perinatal parameters. The data wet was a cooperative study involving 11 Italian cities, distributed nationally. The study group was divided in three categories according to the mother's cigarette smoke exposure during pregnancy, ie, not smokers, passive smokers, direct smokers. Potential confounders, including paternal characteristics, were adjusted for by multiple linear regression analysis. A mean reduction of 16 g (p <0.07) in birthweight and a decrease in birth length of 0.05 cm (p <0.08) were found for each hour of antenatal passive smoke exposure. No or slight effects were reported for the other perinatal parameters considered.
