Prevalence of asthma among preschool children in Edirne, Turkey.

ABSTRACT

Allergic diseases generally begin early during childhood, but a late diagnosis is common. This study aimed to evaluate the prevalence of asthma and asthma-related symptoms among kindergarten children in Edirne, Turkey. 873 subjects based on a modified ISAAC questionnaire were included. The prevalence of 'wheezing ever' and 'wheezing during the previous year' was 23.3% and 8.6%, respectively. Prior physician diagnoses existed for 36 of 873 (4.1%) children. The prevalence of children undiagnosed with asthma, but reporting asthma-related symptoms was 3.1%, 51.9% of which had previous beta-agonist prescriptions. However, none of these children received inhaled anti-inflammatory medications. In conclusion, it was found that a large population of preschool children had undiagnosed respiratory symptoms suggestive of asthma. Conducting simple surveys of young children is particularly important, as identification of asthma early in the disease course will facilitate effective prevention and treatment.
