In recent years, the prominence given to the effects of environmental tobacco smoke or passive health has been in continuous growth, both through the development of scientific research and to the increased attention of public opinion, and were highlighted in particular the consequences that prolonged exposure to secondhand smoke causes in particular groups of the population such as the sick and children.
In the latter, different pathologies have been associated to secondhand smoke, including diseases chronic respiratory, cardiovascular, one lung development reduced, and even brain tumors.
II passive smoking determines in children an increase in respiratory illnesses and a doubling of hospital admissions for lung problems. Many studies also show an increase in the frequency and severityà of the attacks and asthma and retarded lung development in children exposed to secondhand smoke.
In the blood of the children of smokers have been found carcinogenic substances as well asé nicotine, a substance that can cause dependency.
A study conducted in North America has examined the association between exposure to environmental tobacco smoke and the episodes of acute asthma in children, both through the data collected by a questionnaire or by measuring cotinine (a metabolite specific to nicotine) in the urine.
II relative risk of acute crisis of asthma was increased to 80%, based on the information obtained from the questionnaire, and 70%, based on the measurement biological.
The results of this study are very important, because it; demonstrate and quantify the association between two serious lung diseases in children (bronchial asthma and reduced functionalityà pulmonary), and the smoke of their parents.
prevention through a correct and constant information is therefore a fundamental tool to obtain an awareness on the part of the parents of the potential harm caused by their behavior to themselves and to their children.
