[Influence of exposure to cigarette smoke on clinical course of bronchial asthma among Silesian children].
Bronchial asthma belongs to the group of illnesses of allergic and inflammatory origin. Despite numerous research divergent results are described in literature, that is the reason why a decision was made to conduct a careful study of the influence of various factors on induction and clinical course of bronchial asthma among children. The research included 5945 children of 10-11 from 86 primary schools of the Katowice province (presently Silesian province). The factor evaluated was the influence of the exposure to tobacco smoke on asthma induction and its clinical course. The data concerning the exposure were obtained from the children's parents. The dependence analyses were conducted with the use of statistical packets Statistica and BUGS. Smoking was declared in 3594 cases (68.5%), and non-smoking were 1637 people (31.2%). The probability of developing asthma is constant within the range of 0-40 cigarettes smoked daily; then it grows quite rapidly (R-0.794, p-0.011). The clinical course of asthma was evaluated on the basis of appearing wheezing respiration, pressure in chest, dyspnoea and cough. In the investigated population/group only the probability of pressure in chest incidence correlated with the number of cigarettes smoked (R-0.86, p = 0.014), in case of the remaining symptoms the correlation was statistically insignificant. The obtained results have proved a substantial influence of tobacco smoke on the development of asthma. This indicates the necessity of taking sanitary measures in the habitats, and especially elimination of tobacco smoke. The results of the research concerning the influence of tobacco smoke on clinical course of asthma were less unequivocal. This might be caused by the evaluation method of the exposure (purposeful underrating, smoking away from home, or in another room). This points to the necessity to employ a more unbiased method of evaluation of the exposure to tobacco smoke.
