According to a study conducted by a group of European researchers, men transmit significantly smoking to their sons, while women his daughters. The study throws the same way an interesting result: the fact that the mother smoke does not appear to affect the probability that the son smoke, or vice versa. This research is based on data from the survey Panel homes British 1944-2002. According to the researchers, that selected data source since it outlined in detail products consumed in households, including tobacco, allowing analysis of the intergenerational transmission of cigarette smoking. This research was conducted in households with both parents present, and single-parent households (those headed by mothers primarily). According to Maria Loureiro, co-author of the study, the results obtained show that in terms of smoking habits is concerned, and after having checked the socio-economic variables, tobacco prices and the location of the home, the daughters tend to imitate their mothers, and sons their fathers. In conclusion, the importance of these results from a point of view of design and public policy to combat smoking is clear. Those that successfully reduce smoking fathers and mothers will directly affect their descendants.
