Scheme using which person starts smoking
A lot of people consider that usually teenagers adopt vicious habits, including smoking, from their age-mates. But it appeared that that's not true at all.
Scientists from Santiago-de-Compostela University have determined that most often teenagers adopt vicious habit from their parents. And boys adopt it from fathers but girls from mothers.
Such conclusions were made basing on examination of families in period from 1994 to 2002. Girls tend to imitate their mothers but boys - fathers. If both parents smoke probability that son will start smoking is 24 % and for daughter this probability is 23 %.
If nobody smokes in the family, children start smoking only in 12 % of cases. In single-parent families vicious habit was transmitted regardless of child's sex and parent.
