Asthma is the most frequent chronic disease in childhood. Over recent years an increasing prevalence of asthma has been proved in many epidemiological studies.
In 1997 we conducted a survey among students of two secondary schools in Łódź. The study included 775 students aged 15-20 years. The applied questionnaire contained 70 detailed questions based on ISAAC.
The presence of at least one of asthma symptoms was reported by 10,1% (78/775) of students. Among them 5,4% (4//775) complained of unproductive night cough not associated with infection over last 12 months, 5,5% (43/775) of wheezing, 4,9 % (38/775) of wheezing episodes. In this group asthma diagnosis is highly probable, though it was earlier diagnosed only in 2,2% (17/775). Among asthmatic patients risk factors were more common than in other students: hypersensitivity to inhalant allergens-pollens (70,6% vs 9,6%), house-dust mites (58,8% vs 6,2%), domestic animals and pets (52,9% vs 5,3%), infections of the respiratory tract during the last 12 months (41,2% vs 14,2%), passive tobacco smoking (70,6% vs 48%), bad living conditions (41,2% vs 13,2%) and low birth weight (35,3% vs 11,5%).
In conclusion, asthma defined by the presence of clinical symptoms has been found in 10,1% adolescents in Łódź, but prior asthma diagnosis had been established only in 2,2% of the study population. The group of adolescents with asthma symptoms requires further medical observation.
