Bronchiolitis is a major cause of hospitalization for infants and passive and active maternal TSE during pregnancy seems to be significant RFs that can be modified. According to the tendencies found in this study, the elimination of smoking during pregnancy and the avoidance of second-hand TSE in the environment where pregnant women live are mandatory in order to reduce morbidity of newborns and young infants, also in the presence of other non-modifiable RFs for bronchiolitis. Moreover, since women are more likely to quit smoking during pregnancy than at any other time, there are efforts to increase motivation and help women who are planning to conceive to stop smoking at the procreative phase of their life or during pregnancy. Finally, studies on respiratory tract infections in infants at a later age are necessary to examine the long-term effects of maternal TSE during and after pregnancy. The results of the present study will be used by the Italian Neonatology Society, that supported the study, to improve counselling to families and pregnant women to reduce tobacco smoke exposure.
