title: [Respiratory risk among students in an industrialized area of Sardinia: role of smoking and air pollution].
abstract: Among 273 students (age 11-16 years) living in two small towns located respectively 2 (Portoscuso) and 15 kilometres (S. Antioco) far from the industrial area of Portovesme, the respiratory risk associated to cigarette smoking and environmental pollution was evaluated by the ISAAC questionnaire and standardized spirometry. The prevalence of parent's smoking was high in both groups (66.3% and 59.4%). Smoking during pregnancy was reported by 15% of mothers, without significant differences between the two schools. The prevalence of smokers among students was similar comparing the two groups (7% vs 6%). The prevalence of asthma in the whole population was significantly associated to skin positivity to common allergens, to the familiarity for asthma and to the environmental tobacco smoking, particularly if maternal. Spirometric values were significantly lower among students living in Portoscuso than among those of the S. Antioco school, with an evident interaction between the residential factor and the tobacco smoking, active and/or passive, in reducing the forced end- expiratory flows. Our results support the significant role of tobacco smoking, active and passive, particularly if derived from maternal smoking during pregnancy, in increasing the prevalence of respiratory disorders and lowering lung function in children. Living in Portoscuso, because of higher environmental exposure to airborne pollutants of industrial origin, has been shown as a relevant factor further lowering the lung function among the studied sample.
