The study was aimed to investigate the occurence of allergy symptoms and atopy features among Łódź school children in relation to environmental conditions at home and school. The study population was randomized and included students of two different environments of city elementary schools. The single symptoms that might prove reversible bronchial obstruction, as: dyspnoe during infections, dyspnoe following exercise, wheezing, cough at daytime and nighttime or use of bronchodilatators was reported by 2-12% of children, wheras at least one of those symptoms was repoted by 47.1% of studied children. Rhinitis symptoms were confirmed by 30.6% of surveyed children; among those approximately 47.1% reported simultaneous conuctivitis symptoms. 4% children were under constant care of allergy specialist. As much as 70.6% of the children confirmed constant exposure to allergens of domestic pets, whereas 65.4% were exposed to cigarette smoke. The positive skin tests to at leat one of the atopic allergen were found in 40,2% children. Allergy incidence among school B students was twice of that among school A students. The differences among the schools were also related to the incidence of bronchitis, family status, place of living and the pet owning. There was a correlation between allergy to distinguished groups of allergens and the symptom incidence (wheezing, coughing, dyspnoe, number of infections) as well as environmental conditions (living place, smokers and pets at home). There was no correlation between having a brother or sister (including elder one) and the occurence of atopy features.
The results indicate that there is a high incidence of allergy to atopic allergens and lower airway symptoms among Łódź school children. The incidence of allergy and respiratory symptoms correlates with some environmental factors.
