PASSIVE Siv10K1i~IG <br /> Passive smoking is a cause of additional episodes and increased severity of symptoms <br /> in asthmatic children. Asthmatic children are up to 2.5 times more likely to Gave their condition <br /> worsened by passive smoking. In the United States alone it is estimated that <br /> 200 000 to one million asthmatic children have their condition worsened by passive smoking. <br /> Exposure to environmental tobacco smoke (ETS or "passive smoking") is a risk factor <br /> for new cases of asthma in children who have not previously displayed symptoms. <br /> The risk of lower respiratory tract diseases (such as croup, bronchitis and pneumonia) <br /> is estimated to be about 50-60% higher in children exposed to ETS during the first i-2 <br /> years of life, compared with unexposed children. About 10-15% of lower respiratory <br /> tract disease in young children under 18 months of age is attributable to passive <br /> smoking. <br /> 1n children, exposure to environmental tobacco smoke is causally associated with <br /> increased prevalence of fluid in the middle eaz, symptoms of upper respiratory tract <br /> irritation, and a small but significant reduction in lung function. <br /> Environmental tobacco smoke is a cause of lung cancer in lifelong non-smokers <br /> exposed to ETS. Epidemiological studies carried out in several countries suggest that <br /> <br /> the lung cancer risk is about 20-30% higher than for never smokers not exposed to <br /> <br /> ETS. <br /> <br />
