In order to determine asthma prevalence in 6-12 year old school-children in Istanbul, we issued 2350 questionnaires delivered in 6 different regions of the city to be filled at home by the parents. 2232 of the questionnaires were returned completed with an overall response rate of 94.9%. 2216 questionnaires were taken into consideration. In the epidemiological definition of asthma, self-reporting of diagnosed asthma by a physician confirmation was used. 218 cases were diagnosed as asthma. The prevalence of asthma was found to be 9.8%. The risk factors which could be responsible for asthma, gender, smoking at home, presence of domestic animals (cat, dog, bird), stuffed toys, home dampness and breast feeding were evaluated. On the other hand socio-economic status (annual family income, education of mother and father, being owner or occupant of the house, heating system, total number of rooms in the house, large family, sharing of bedroom) were scored for each condition as 1 point for bad and 2 points for good conditions. In conclusion, the prevalence of childhood asthma was not affected by any of these factors. Atopic family history, food allergy, eczema, frequent otitis media and sinusitis attacks were evaluated and found to be significantly effective in asthma prevalence. © 1997 Wiley-Liss, Inc.
