Smokers physically "give" their children to the habit

Smokers physically Children begin to smoke not only in imitation of parents, but also because their lungs are "attached" to Smoking at home, say canadian researchers. They suggest that parents Smoking in front of children, causing more harm than you think. They not only set an example, but also acquaint the children with the taste of tobacco, increasing the likelihood that they will become smokers. The group of the Montreal Institute of chest, headed by Margaret Belak watched growing up about 200 children. When they were about nine years, scientists have measured the concentration cotinine in their saliva. Cotinine is a metabolic byproduct of nicotine that causes tobacco dependence. Inhalation of tobacco smoke nicotine turns into cotinine, and you can measure its concentration in blood and saliva. Scientists writing in the Canadian Medical Association Journal that the concentration cotinine children was different. Only one child at this stage revealed the level cotinine, leading to the idea that he already smokes. Re-examination of the scientists conducted when children were approximately 13 years. To this point, 80 % of them were high school students and 44% were smokers. Scientists have found that the level cotinine identified in the first stage, which is a fairly accurate indicator of whether children to smoke to the second stage. Especially those who started Smoking at an early age. Those whose level cotinine in nine years was a high chance that they will be Smoking, not having reached puberty, was twice as high. For those who have already entered puberty, kotinen not had such a large value, increasing the risk of only 20 %. Scientists emphasize that the number of participants was small and the findings should be interpreted with caution, but the results are nonetheless impressive. Meanwhile, the researchers found no relationship between the number of smokers in the family and the chances of the child to smoke in adolescence. The relationship between the level cotinine and subsequent Smoking persists after adjustment for socio-economic status of parents, number of smokers in the family and the number of house smoked cigarettes. Scientists have found a weak relationship between lung volume and susceptibility to Smoking. They write: "We believe that the size of the lungs increases the quantity of inhaled smoke, maximizes the impact of passive Smoking on children and encourages Smoking in adolescence". The commentary in the same journal canadian doctors Nicolas Anthonisen and Robert Murray writes that when the connection is confirmed, she will give a simple explanation of how Smoking is transmitted from generation to generation, and can become the basis for campaigns against Smoking. Ian Willmore from the Organization for the tobacco said: "first of All, children of Smoking parents imitate them, learn from their example. It is not surprising that the concentration cotinine in the blood and saliva of these children above the norm, because my parents smoke at home." "Secondly, can be found alarming evidence that nicotine, which appear in the saliva due to passive Smoking, can lead to physical dependence, and the study allows to draw such a conclusion". "It is important to draw the attention of parents to the fact that Smoking home, they harm the health of their children, and that if they smoke, the likelihood that children will be to smoke increases". Children begin to smoke not only in imitation of parents, but also because their lungs are "attached" to Smoking at home, say canadian researchers. They suggest that parents Smoking in front of children, causing more harm than you think. They not only set an example, but also acquaint the children with the taste of tobacco, increasing the likelihood that they will become smokers. The Times (Russian text Inopressa.Ru).
